Unexamined Japanese Patent Publication No. 2018-59706

Communication based on LPWA (Low Power Wide Area) is generally known to consume less power than 4G or 5G.

The invention of the present application aims to further suppress power consumption in a system that controls communication means using LPWA, which generally consumes less power than communication using 4G or 5G, for example. Furthermore, the present invention is not limited to this, and the object is to provide a system that is superior to the conventional system.

The purpose of the invention of the present application is not limited to this, and we intend to acquire rights through divisional applications, amendments, etc. for structures that aim to obtain effects from the parts of the structure disclosed in this specification, drawings, etc. . For example, the present specification discloses a problem in which the phrase ``can be done'' is replaced with ``the problem is.'' Each issue is described as an independent entity, and we intend to acquire rights to the structure for solving each issue individually through divisional applications, amendments, etc. Even if the problem is implicitly understood from the description of the specification, the present applicant has the intention to claim a part of the structure described in the specification in an amendment or divisional application. The company also discloses a structure that solves a problem that combines these independent problems, and has the intention to acquire the rights to it.

(1) A system for controlling communication means using LPWA (Low Power Wide Area),
The system may include a power consumption suppressing means for controlling the communication means so as to suppress the power consumed.

Power consumption is suppressed compared to the case without the power consumption suppressing means.
For example, it is preferable to use LPWA that realizes long-distance data communication with lower power consumption than communication systems such as 4G and 5G. LPWA may use, for example, a 920 MHz band. For example, LPWA may be capable of long-distance transmission of several kilometers with low power consumption. For example, it is preferable to use LPWA with a low bit rate and a limit on the amount of transmission per period.

Examples of LPWA include "ELTRES", "LoRa", "LoRaWAN", "LTE-MTC", "NB-IoT", "NB-Fi Protocol", "RPMA", "GreenOFDM", "DASH7", "RPMA", "Wi-SUN", "EnOcean". It is preferable to use at least one of "Long Range", "Weightless-P", "SIGFOX", "LTE Cat.0", "LTE Cat.M1", etc.
In particular, the system may be configured as a battery-powered device.
As a method of controlling to suppress power consumption, for example, methods exemplified in (2) to (22) described later may be used. In particular, the data sent in this way may be stored in a database on the receiving system, but it is extremely preferable to store it in a blockchain.

(2) The power consumption suppressing means may be a system that causes the communication means to transmit a specific type of data that has a smaller amount of data than other types of data.

It sends less data than systems that send other types of data.
The content of the control for controlling the communication means to suppress power consumption is such that the power consumption suppression means causes the communication means to transmit a specific type of data that has a smaller amount of data than other types of data. Good to control.
For example, a taxi calling device equipped with an LPWA communication function, a taxi calling button, and a display is installed in a facility such as a pub. Taxis will be equipped with GPS and LPWA communication functions, as well as vacancy notification devices with vacancy buttons and display devices that can be operated by taxi drivers. The taxi calling device stores a different facility ID for each device, and when a press of the taxi call button is detected, the stored facility ID is wirelessly transmitted to the server using the LPWA communication function. The taxi's vacancy notification device has a button that is held when the vacancy button is pressed and when it is not pressed. The taxi ID, which is different for each taxi, is associated with the current location information from the GPS and sent to the server every minute (the server also has an LPWA communication function). The server stores the facility ID in association with the facility's location information, facility name, etc., and when the facility ID is sent to the server, the taxi company will be able to respond to the application running on the installed tablet. Then, the system sends a push notification of the location information of the facility, the facility name, the location information of a taxi that is within a predetermined range from the location of the facility, and that has transmitted location information within a predetermined period of time, and the taxi ID. When the tablet app receives this push notification, it displays the location of the taxi, the time the current location information was received, the location of the facility, and the time the facility ID was received on a map. The dispatcher at the taxi company looks at the displayed positions of the taxis, the locations of the facilities, and the respective reception times, and touches the taxi to be dispatched from among the displayed plurality of taxis. The tablet sends the taxi ID of the touched taxi to the server as the taxi ID to be dispatched together with the corresponding facility ID of the dispatch destination. The server uses the LPWA communication function to send the facility name and facility location information of the destination facility ID to the vacancy notification device of the taxi ID, and also sends the location information of the taxi with the taxi ID to the taxi calling device. Information on the expected arrival time calculated from the route and the location information of the destination facility is transmitted. When the taxi calling device receives this, it displays on the display the fact that the taxi is being dispatched and the expected arrival time. The vacant vehicle notification device of the taxi ID that receives the facility name and facility location information of the facility ID of the destination uses the received information to display the route to the facility of the destination on the display device, and also indicates that the vehicle is vacant. Releases the button from being held down.
In this way, a taxi requester can call a taxi with a single button. Facilities such as stores can simply install a simple device, which is smaller than a smartphone and does not require charging, near the cash register or waiting area. The taxi company will be able to learn about taxis near the customer and be able to deliver the taxi to the requested location.
It should be noted that the taxi calling device may be provided with a taxi recall button to similarly transmit a notification to the server that there has been a taxi recall. In addition, the taxi calling device has a function to input the number of taxis you wish to dispatch, and the information on this number is also sent.The server side sends a push notification to the app along with the information on the number of taxis, and the app also sends the information on the number of taxis. Alternatively, the number of taxis may be displayed on a map and the number of taxis corresponding to that number may be selected from the map. Furthermore, a function may be provided to display a list of press times of call buttons and to cancel a call button pressed by mistake. In this case, the information about the cancellation, the number of the cancellation target on the list, and the facility ID are sent to the server side, and the server side displays the cancellation on the map display based on this information. At the same time, if a taxi has already been dispatched, cancellation information is distributed to the taxi calling device and vacancy notification device. In response to this, each device should display a message to the effect of cancellation, and return the empty car button to the state in which it is pressed. Further, the server may be a blockchain server, particularly a blockchain that is shared by tablet apps of multiple taxi companies.
For example, a so-called golf navigation system may be equipped with an LPWA communication function, and may have a function of transmitting information on the user's ball hitting position to the server side using the LPWA communication function. For example, on a golf course, a golf navigation has a function that notifies the user of the distance from the current position measured by GPS etc. to the pre-stored position of the pin of the hole on the course currently being played, and It is particularly preferable to have a configuration in which a location registration button is provided that is pressed by the user, and location information of the location where the location registration button is pressed is transmitted to the server using the LPWA communication function. Furthermore, it is preferable that at least one of the following functions is provided, and preferably all of the following functions are provided. It would be good to have a function to memorize the location registered using the location registration button. It would be good to have a function to memorize the location registered using the location registration button. It is preferable to send information about the location where the point registration button is pressed, which is transmitted using LPWA, in association with time information about the time at which the button was pressed. Transmission by LPWA may be performed immediately when the point registration button is pressed, but it may be possible to send the cup-in by a button for inputting a cup-in instruction from the user, or by detecting the cup-in by GPS. The position of the location registration button on the hole that was being played before the movement based on at least one of the following: the current position has been moved to the position of another pre-stored hole, or movement has been started It is particularly good to send the information history all at once to the server side using the LPWA communication function. Furthermore, it is preferable to have a function to transfer the memorized position to another device such as a PC after playing, or a function to display the position on the hole corresponding to the memorized position together with a schematic diagram of the golf course.
Further, it is preferable that a so-called radar detector is equipped with an LPWA communication function, and has a function of transmitting witness information such as enforcement from the user to the server side using the LPWA communication function. It is preferable to send the location information from the user where the post button was pressed to the server side along with the time information when the button was pressed using the LPWA communication function.

(2-1) When the other types of data are, for example, unprocessed data (for example, so-called raw data), the specific type of data may be data after these processes.

It is preferable to perform a process of converting the data before processing into the data after processing.
The data before processing may be, for example, data detected or measured by a sensor, a measuring device, etc., or data indicating an entity.
The data before processing may be, for example, text data, while the data after processing may be binary data.

The processed data may be, for example, data obtained by subjecting the unprocessed data to reversible compression, irreversible compression processing, etc. focusing on redundancy, etc.

In addition, the processed data may be representative values or statistical values such as arithmetic mean values, geometric mean values, median values, mode values, etc., obtained by performing statistical processing on multiple unprocessed data, for example. It is preferable to use data that shows. The processed data can be, for example, statistical values obtained by statistically processing the sample data of accident data, learning model data generated by performing machine learning on the sample data, and the input and output of the learning model data. It is preferable to use distillation model data etc. generated by Machine learning may be used, for example, to predict equipment failure.

In addition, in artificial intelligence, especially artificial intelligence that performs deep learning, trained model data is equivalent to statistical information compression of the data used for learning, so the amount of data is smaller than the data used for learning. small. Therefore, it is preferable that the data before processing be used for the above-described learning, and the data after processing be used as trained model data used in artificial intelligence. In particular, the processed data may include, for example, the number of layers of a neural network, the number and configuration of neurons in each layer, the network connection configuration between each layer and its weight, a firing function and its threshold value, etc. In particular, it is preferable that the processed data include only the portions that change due to learning. In particular, the processed data may be weighted data. In this way, a particularly excellent effect can be achieved in normal learning in which the static configuration of the neural network is not dynamically changed. It is preferable to use a format for the processed data that can be exported from multiple frameworks and is relatively small in size. In particular, it may be NNEF, but it is better to use ONNX (Open Neural Network Exchange Format).

In this system, for example, when identifying a sign or a vehicle by image recognition using learned model data, the initial model is stored in the drive recorder when shipped from the factory. If there is an error in image recognition, it is preferable to have the user press an operator such as a button as an input for correction. It is preferable that this system performs supervised learning to correct this error by the user on the edge side (in this example, the drive recorder). As a result, a derived model is created on the edge side of the initial model. Furthermore, multiple derived models are created simultaneously using the drive recorders of multiple vehicles. The edge side in this system preferably transmits this derived model to the server at a predetermined timing. The predetermined timing may be the timing when the vehicle travel distance reaches a predetermined distance, or the timing when it is detected that the amount of change in the model has increased, but it is possible to improve the evaluation results based on the evaluation image data on the edge side. It is especially good to choose the timing when this is seen. The improvement of the evaluation result may be determined, for example, by comparing a numerical value included in the evaluation result and serving as an evaluation index with a threshold value.

This system records the information used for learning on the edge side on removable media such as an SD card, and when connected via a communication means other than LPWA, this information is sent to the server along with information that associates it with the learning data. It's a good idea to send it.

On the server side, the evaluation images are used to evaluate the model data sent by this system from each vehicle's drive recorder, and the best one is distributed all at once from the server to drive recorders that have not yet been trained. This is especially good since it seems that a significant number of users do not press the button even if they make a mistake, that is, they do not cooperate with the learning process and use the default settings.

On the other hand, it is preferable that this system not distribute information to drive recorders that have progressed in individual learning. In addition, this system distributes data individually to drive recorders that are progressing in learning, and determines which has higher performance, the model data delivered on the edge side or the data that has already been learned by that drive recorder. It is a good idea to evaluate and hire the best one. This is because the content of the video changes depending on the method of mounting the drive recorder, etc., so model data that is highly evaluated on the server side is not necessarily the best model data for the video of that drive recorder. Note that if there are multiple edge sides (drive recorders, etc.) that have not yet been trained, the server may send the best model data to each of those edge sides on a one-to-one basis, but as described above, LPWA It is best to broadcast all at once using connectionless communication.

When a derived model is sent to a server, etc., this system blocks the hash value of the model data along with the ID of the edge device that generated the derived model, the ID of the owner of the edge device, and preferably both IDs. It is better to write it in the chain. In this way, the right holder of the derived model can be easily identified.

Further, the processed data may be, for example, data extracted from the unprocessed data by satisfying a predetermined condition.

The processed data may be, for example, data extracted for calculating insurance premiums from data obtained by measuring driving behavior.

Further, when the data before processing is, for example, POI (Point of Interest) data before change, the data after processing may be the difference between the POI data before and after the change.

Further, the processed data may be data extracted at a certain point in time from among a plurality of unprocessed data whose values may vary over time.

For example, when the unprocessed data is entity data that represents an object that represents an entity, the processed data may be data that indicates the results of a judgment made by a machine or a human on this entity data. . The data after processing may be, for example, a comparison result between the data before processing and a threshold value.

Processed data includes, for example, image data representing the image itself, data representing the result of recognizing the image, information representing whether the measured value of impact exceeds a threshold, and user behavior itself. Information that labels the behavior for data that shows the behavior, data that shows the result of the user's recognition of the CAPTCHA for images for CAPTCHA, etc., and whether or not the measured value of alcohol intake exceeds the threshold. It is preferable to use data showing the results of a judgment on the danger of drunk driving, etc., or the results of an inspection of a measured value of a vehicle or the like subject to maintenance inspection.
On the receiving side, it is preferable to write the received processed data to the blockchain.

(2-2) When the other types of data are, for example, a plurality of pieces of data, the specific type of data may be identification information or the like assigned to identify the data.

The specific type of data may be, for example, information regarding a vehicle detected at the timing of imaging, recording, or audio recording of each data such as an image of the surroundings of the vehicle, a recorded video, and recorded audio. For example, if the drive recorder included in this system communicates information about the vehicle as a specific type of data, it will not be able to send a video, but it will be able to communicate that an event such as an accident has occurred and its location data.

The specific type of data may be, for example, identification information used to identify the game item with respect to image, video, and audio data indicating the game item itself.

Further, the specific type of data may be, for example, a URI (Uniform Resource Identifier) used to identify each piece of web content data. For example, it may be a URL. In particular, it is best to generate a URL by processing (converting) the actual URL into a URL for a shortened URL service.

The specific type of data may be, for example, detection data indicating that a machine has detected an object, or report data indicating that a user has found an object.

Specific types of data include, for example, detection data indicating that a radio wave detector has detected radio waves (radar waves) output by automatic speed enforcement devices, radio waves of a specific frequency used by police radio, etc. It is good to say.

In addition, certain types of data can be obtained, for example, by analyzing images taken on the road, recognizing traffic riot police officers, police officers, or their vehicles (police cars and motorcycles) in the images, and indicating that they have been detected. It is preferable to use the detection data as shown.

Further, the specific type of data may be, for example, report data in which the user reports that he or she has found an automatic speed enforcement device or a traffic police officer by visual inspection or the like.

This system is equipped with a detection device that measures the position of the detection device itself using the Global Navigation Satellite System (GNSS), etc., and a report button for an automatic speed enforcement device inside the vehicle, and outside the vehicle. It is preferable that the detection device is configured to include a server, and when the user presses this notification button, the detection device sends coordinate values indicating its own position to the server. This allows the system to collect big data from speed enforcement conducted in real time. Further, the server in this system preferably acquires traffic congestion information in addition to coordinate values.

For example, this system is equipped with a detection device in the user's home or car to detect abnormal situations such as intrusion or fire, and when such an abnormal situation occurs while the user is away and is detected by the detection device. In addition, it is preferable to notify the user by e-mail or the like of a specific type of data, such as a notification that an abnormal situation has been detected.

In particular, the present system may also include an imaging device, and when the detection device detects the occurrence of the above-mentioned abnormal situation, the image captured by the imaging device may be sent. When an abnormal situation occurs, each abnormal situation includes, for example, a 20-byte command header, 16-byte data indicating the date and time, and 4-byte data indicating the type of abnormal situation. A total of 40 bytes of data are sent to the server. Further, in addition to the 40 bytes of data described above, 327×252 (82404 pixels) image data is added, and a total of about 40 kilobytes of data is preferably sent to the server.

If a total of approximately 40 kilobytes of data is sent to the server each time an abnormal situation occurs, for example, if 10 abnormal situations are detected in a month, a total of 400 kilobytes of data will be sent per month. is sent. The email used for transmitting data is preferably sent to a server, and from the server, for example, to a mobile terminal such as a user's smartphone (hereinafter also referred to as "smartphone"). In this case, it is possible to reduce the amount of data at the server compared to when the data does not go through the server. The above email may be sent directly to the user's smartphone or the like via free email or the like.

When the other types of data are, for example, image data representing images or audio data representing sounds, the specific type of data may be character data representing characters.

SNS data such as Twitter and Instagram mainly consists of text data, image data, and video data. It is preferable for this system to send only character data, and to send image data and video data using communication means other than LPWA. This system may be configured so that information is added to and sent to each of text data, image data, etc. in order to link them, and the server side links and processes the correspondence between the two.

For example, when other types of data are data that exceeds the amount that humans can recognize, memorize, input, etc. at one time, a specific type of data is data that does not exceed this amount. good.

The specific type of data, for example, character data, may be character data within the optimal number of characters to convey a coherent meaning.

As an example of the optimal number of characters to convey a comprehensive meaning, it is recommended to use the typical number of characters that can be written on a postcard, for example. Further, as an example of the optimum number of characters to convey a comprehensive meaning, it is preferable to use, for example, 70 full-width characters or 160 half-width alphanumeric characters, which are used in short message service (SMS).

In particular, the specific type of data may be character data, for example, character data within the number of characters that humans can memorize at one time using short-term memory.

An example of the number of characters that a human being can memorize at one time using short-term memory is, for example, about 3 to 9 characters.

Due to the nature of the specific type of data, it is preferable that the amount of data is smaller than other types of data.

Specific types of data include, for example, information for authentication, credentials consisting of a user ID and password, information such as the driver's name, date of birth, and permanent address written on a driver's license or stored electronically; Identification information, vehicle information, data indicating roll call, data on detecting an intruder indoors when you are not home, hash value for blockchain, etc., data generated by one transaction in blockchain, timestamp, Ethereum Scripts and source code of contract-oriented languages such as Solidity used in blockchain platforms such as ``Solidity'', hashtags used in SNS, etc., identification information such as stamps and emojis used in SNS, contact input data, count results It is preferable to use data indicating opening/closing detection data such as thumb turn, permission information given by the user when downloading or executing an application program (referred to as an application), data on weight measurement of stored items, etc. The system may use certain types of data, for example as evidence.

The above-mentioned information for authentication may be, for example, the result of checking the user's (driver's) license or drinking condition by a driver's license reading device installed in the car or an alcohol checker. A device installed in the car sends the results of these checks to the server before the start of operation. In particular, it is preferable to send information in which information for identifying the driver (for example, driver ID, etc.) is associated with information on the check results.

For example, the data sent in one trip is a total of 36 bytes, including a 20 byte command header, 12 bytes of data indicating the driver's license number, and 4 bytes of data indicating the alcohol measurement result. . In this case, the amount of communication will be approximately 1 kilobyte per month, assuming once a day. The server preferably manages the history.

The hash value for the blockchain etc. described above is preferably a hash value recorded when a user who uses the distributed database of the blockchain updates this distributed database. Although the block itself increases each time it is updated, the hash value of the block at a certain point in time is smaller than the block itself, so the amount of data sent is suppressed. Furthermore, the contents of the publicly available distributed database can be referenced and updated by participants in the blockchain, and since the next block contains the hash value of the previous block, it is virtually impossible to tamper with the information in the block. Therefore, it is extremely useful for data accumulation and distribution between parties with conflicting interests. Due to these characteristics, blockchain is widely used not only for virtual currency but also for distribution, for example. This system transmits a hash value that indicates which vendor currently handed over the cargo to which vendor as a specific type of data, and records it on the blockchain to trace items between parties participating in the supply chain. It is good to make it complete and easy. Further, this system may be used, for example, between the person who purchased the advertising space (advertising company) and the company that sells the advertising space (advertising agency, etc.). Furthermore, this system may transmit a hash value indicating the fulfillment status of all contracts in which there is a conflict of interest as a specific type of data and record it on the blockchain. Furthermore, this system may transmit a script as a specific type of data and record it on the blockchain so that the next contract or factual action is automatically performed programmatically in response to the execution of the contract.

Furthermore, the above-mentioned "data generated in one transaction in the blockchain" is data generated each time the distributed database of the blockchain is updated. For example, in the case of virtual currency, the amount of this data is limited to the amount of information transferred from whom to whom. Therefore, the present system preferably transmits this data as a specific type of data.

Further, the present system may be configured to execute the smart contract when it is detected that the sensor is in a specific state or that a specific operation is performed by the user.
For example, when signing an insurance contract, this system sets the smart contract conditions to execute a contract that increases the insurance premium by 0.1% if acceleration equivalent to dangerous driving is detected. In addition, this system sets the conditions of the smart contract to execute a contract that reduces insurance premiums by 0.1% if, for example, conditions corresponding to safe driving continue for a predetermined period of time. When these conditions are met depending on the driving situation, the system automatically transmits the detection results as a specific type of data and writes it to the blockchain. These contracts are hereby enforced.

In addition, this system can be constructed with a model in which, for example, the unit price is charged high while the amount of usage is small, the unit price is reduced when the amount of usage increases, and after that the usage is unlimited after the amount of usage exceeds a certain amount. good. In this system, the use of the car navigation system is contracted by smart contract, for example, 2 yen per km for the first 5,000 km, 1 yen per km from 5,000 km to 20,000 km, and free for 20,000 km or more. Furthermore, when the user operates the car navigation system and presses a map update purchase instruction button, the present system preferably executes a map update purchase smart contract. Here, since the amount of map update data is large, update it by communication means other than LPWA, SD distribution, etc. After that, in addition to the above navigation fee, 2 yen for the first 2,500 km after map update, 10,000 km. It would be a good idea to execute a smart contract and charge the fee, such as charging 1 yen up to that point and free after that.

Furthermore, when transmitting the above-mentioned game item identification information as a specific type of data, this system is capable of transmitting so-called items such as weapons, armor, and medicine used in the game, as well as, for example, gacha execution, crystal It is a good idea to record on the blockchain the identification information of rights that are granted purchase, time-to-event reduction, and other advantageous conditions.

In addition, this system preferably records information regarding input of user authentication information and consent to access right information on the blockchain. For example, this system may send authentication information consisting of a user ID and password, and record information regarding the validity of the authentication result in the blockchain. Further, for example, information on whether or not permission has been given to access the hardware/software resources of an application may be recorded on the blockchain together with information identifying the application and the details of the permission.

In addition, in so-called private lodging, where tourists stay in ordinary private houses, it is difficult to hand over the keys. It is preferable that this system sends key information indicating the key of the private lodging house, opening/closing information indicating the opening/closing of the door, etc. to the server etc. using LPWA. Since the amount of specific types of data such as key information and opening/closing information is smaller than other types of data such as video data, this system reduces power consumption when sending data to servers etc. using LPWA. Suppressed compared to sending other types of data. In this system, instead of sending the key information itself to the server, it is preferable to generate a hash value of the key information and send it.

Further, when the server or the like receives key information, a hash value of the key information, opening/closing information, etc., it is preferable to write these to the blockchain together with information on the time of reception. Blockchain is robust against tampering, so it can be used as proof of lodging records at private lodging facilities.

Furthermore, the server or the like may be linked to the thumb turn that opens and closes the door, or may communicate with the device that drives the thumb turn using LPWA. The server or the like may authenticate the key information received from this system, and when the authentication is successful, instruct the device that drives the thumb turn to open the key. Since power consumption is suppressed by LPWA, the reduced power is used to drive the thumb turn, resulting in a relatively long battery life.

In addition, the power consumption suppressing means transmits data indicating the result determined by edge computing in association with the contact input described above to the communication means as a specific type of data regarding a large amount of information output in time series. It is recommended that you send it to Examples of large amounts of information output in time series include outputs from various sensors such as microwave sensors, audio, video, and the like. Edge computing includes, for example, processing that recognizes only large amounts of information that are output in chronological order while the contact state is on. In other words, for example, if the above-mentioned "large amount of information" is a video, this system recognizes the object included in the video through a deep learning model, and uses the probability vector that is the result of recognizing the object, etc. It is preferable to have the communication means transmit the time information along with the time information.

The data indicating the above-mentioned count results indicates, for example, the traffic volume that is counted manually or mechanically in traffic surveys conducted throughout the country for new road construction and other urban planning purposes. Examples include data. Counting traffic requires one person to operate four to eight counters in order to record what types of moving objects have moved from which direction to which direction. In addition, at intersections where many people and cars come and go, 4 to 10 observation points are required for each intersection, and an observer is required for each observation point, so this work requires a rotation of observers. Including personnel, it is necessary to secure around 8 to 20 people. Therefore, there are problems in that labor costs are high, it is difficult to secure human resources, and measurement accuracy is also poor.

Therefore, it is preferable that this system counts the traffic volume using a camera and image recognition, and transmits the count result to a communication means. Since it is sufficient to send the count results for one day, the communication amount of the communication means in this system is sufficient to be about several tens of bytes per day.

The contacts and the like that generate the above-mentioned contact inputs may be attached to the delivery box, for example. In this system, when a courier company or a participant who participates in the sharing economy as a service provider puts a package into a delivery box, it is preferable to have the communication means described above send a package delivery completion signal. In addition, this system installs a weight scale such as an electronic balance or a spring scale in the delivery box, and measures the weight of the items stored in the delivery box.The system transmits the weight measurement data obtained by using the above-mentioned communication method. It is recommended that you send it to
It is preferable to record specific types of data in a distributed ledger such as a blockchain, while recording other types of data in a predetermined server of a general database (such as a relational database, NoSQL database, etc.).

(2-3) When the other type of data is, for example, data that has already been transmitted by a communication means other than LPWA, the specific type of data may be data other than the transmitted data.

Specific types of data include data that can be sent by LPWA communication means controlled by this system, other than data that has already been sent by other communication means other than LPWA, such as smartphones, proximity communication, 4G, 5G, etc. It is preferable to select one from among the following.
In particular, the system should not transmit data that has already been transmitted by a communication means other than LPWA.

(3) The power consumption suppressing means may be a system that does not cause the communication means to transmit data indicating images.

The amount of data to be transmitted is smaller than when transmitting video.
As the content of the control for controlling the communication means so as to suppress the power consumption, it is preferable that the power consumption suppressing means controls the communication means not to transmit data indicating an image. Further, as the content of this control, it is preferable to control the communication means so as not to transmit data indicating an image, and to transmit a specific type of data, for example, as shown in (2).

(4) The power consumption suppressing means may be a system that does not allow the communication means to transmit the data under certain circumstances even if there is data to be transmitted.

Power consumption due to data transmission is suppressed under certain conditions.
The data to be transmitted may be, for example, the specific type of data shown in (2).

The predetermined situation may be a situation in which the environment of this system satisfies or does not meet predetermined conditions. The environment of this system may include, for example, time, elapsed time, location such as latitude, longitude, and altitude, communication environment, available power amount, whether information or signals are acquired, and combinations thereof.

In particular, the determined conditions may be a combination of a plurality of conditions. The determined conditions may be predetermined rules, patterns, combinations thereof, or the like.

For example, when a system that sends data related to the detection of a certain object detects the object under certain conditions, the detection itself may be incorrect. For example, when the system detects radio waves in a predetermined band output by an automatic speed enforcement device or the like, the same radio waves may also be used by automatic doors of various stores such as convenience stores. In this system, if a detection device controlled by this system enters within a certain distance from these stores during business hours, it may detect radio waves emitted by an automatic door or the like that is not intended for the purpose.

This system measures the location of the detection device using, for example, GNSS, identifies the current time and the location of the detection device, and determines whether the detection device is present at a predetermined time and location. . Then, when this system determines that a detection device is present at that time and place, it is preferable not to transmit detection data indicating that detection has been performed. As a result, unnecessary data transmission is suppressed under determined circumstances, specific types of data to be transmitted are further thinned out, and power consumption due to data transmission is suppressed.

(5) The power consumption suppression means may be a system that transmits the acquired data at adjusted intervals.

The amount of data to be sent is less than if the acquired data were to be sent at uncoordinated intervals.

An adjusted interval is defined as an interval that is at least longer than the interval at which the acquired data is acquired, so that the number of times data is transmitted is less than the number of times the acquired data is acquired during a predetermined period of time, such as a day or a week. good.

The adjusted interval may be, for example, an integral multiple of the interval at which acquired data is acquired (however, the integer here is a positive integer excluding 1). If the adjusted interval is, for example, N times the interval at which the acquired data is acquired (N is an integer of 2 or more), the data will be transmitted only once every time the acquired data is acquired N times.

For example, this system stores data indicating the start date and time and end date and time (16 bytes each = 32 bytes), and data of vehicle coordinate values recorded at 5 minute intervals over 8 hours (20 bytes x 96 times = 1920 bytes). ) is transmitted by the transmitting means. This 5-minute interval is an integral multiple of the interval at which the acquired data is acquired.

Additionally, when an event occurs, this system provides a 4-byte measurement value related to the event (for example, a G-sensor value), a 16-byte data indicating the date and time of the event, and a location where the event occurred. 20 bytes of data are temporarily recorded and sent to the transmitting means. The amount of event-related data that is temporarily recorded is 400 bytes, which is the sum of (4+16+20) bytes x 10 times, assuming that the event occurs 10 times a day. In addition, these reports contain 20 bytes of data in total, each representing five types of data: driver ID, driving time, average speed, maximum speed, and mileage, each representing bibliographic information. Included as data shown. Therefore, the system may send, for example, 32+1920+400+20=2372 bytes once a day. The monthly communication volume of this system is approximately 71 kilobytes. Since this system sends reports all at once at the end of a job, it is possible to reduce the amount of data for so-called command headers such as command type and sender information.

Further, the adjusted interval may not be constant. The adjusted interval may be, for example, an indefinite interval determined as a result of transmission at a timing that satisfies a predetermined condition. The timing at which the predetermined condition is satisfied may be the timing at which the system acquires a signal indicating a change in the work content of the person being monitored by the system. For example, if the person to be monitored is engaged in delivery work, this system should send the acquired data all at once when the person to be monitored completes a series of tasks from taking care of one package to sending it to the destination. . The timing at which the delivery task is completed may be determined, for example, by the timing at which a barcode reading device reads a barcode written on a slip handed to the delivery destination at the time of delivery.

Additionally, this timing includes a signal indicating that the system monitoring target has reached a predetermined position, a signal indicating that the moving distance of the monitoring target has reached a threshold, a signal indicating that the moving speed of the monitoring target has exceeded the threshold, It is preferable to use the timing at which the system acquires various signals related to the monitoring target, such as a signal indicating that the value has fallen below the target. Further, this timing is preferably the timing when a taxi or the like gets on or off a passenger. Further, this timing is preferably the timing at which a truck or the like loads or unloads the cargo.

Further, this timing may be the timing when the engine is started or turned off, the timing when the lights are turned on or off, and the timing when the person appearing opens or closes the door.

Further, this timing may be the timing at which the system receives a control signal corresponding to the user's operation from a server device, smartphone, etc. that has accepted the user's operation.

Examples of the above-mentioned predetermined conditions include conditions such as whether or not the engine is stopped. For example, LTE-M has a function to adjust the radio wave transmission interval like eDRX. In the present system, when the engine of a vehicle is stopped, it is preferable to control the transmission interval of radio waves to be longer than when the engine is started.

(6) The power consumption suppression means may be a system that causes the communication means to transmit the acquired data at intervals adjusted based on information indicating the user's LPWA contract details.

The degree to which the amount of data to be transmitted is reduced varies depending on the user's contract details. Information indicating the contents of the LPWA contract is stored in storage means such as a cloud or a server device, and the system preferably acquires information indicating the contents of the LPWA contract from these storage means. The system may adjust the interval at which data is sent based on this information obtained. For example, when a user presses a report button on the above-mentioned automatic speed enforcement device, it is preferable to reduce the amount of communication by making the interval at which detected coordinate values are transmitted longer than the interval between detections.

For example, if the above-mentioned coordinate values are sent at 5-minute intervals, the amount of data per month is, for example, 115 kilobytes. Furthermore, each time the user presses the above-mentioned report button, the detection device detects the sum of, for example, 16 bytes of data indicating the date and time, 20 bytes of data indicating coordinate values, and 20 bytes of data indicating a command header. Sends 56 bytes of data. Note that the reason why the data indicating the date and time is transmitted is because it is necessary to resend the data if the transmission fails. Assuming that reports are sent once a week, this system will send 224 bytes of data in one month. Furthermore, if reported information is received 10 times in one month, the system will receive 560 bytes of data in one month. Adding these together, the amount of data per month is, for example, 116 kilobytes.

(7) The power consumption suppressing means may process the acquired data so that the amount of data to be transmitted is smaller than the acquired data, and transmit the processed data.

The amount of data to be transmitted is smaller than when the acquired data is transmitted without being processed. This acquired data may be made to correspond to the other types of data mentioned above, and the processed data may be made to correspond to the specific type of data shown in (2).

For example, if the data before processing is text data that includes one or more messages or rows that are composed of one or more fields or columns, the data after processing can be created by specifying a specific message or row from this text data. It is recommended that the data be extracted from only a specific field or column.

For example, when the unprocessed data is text data generated in accordance with standards such as NMEA0183 (hereinafter simply referred to as "NMEA"), which is defined and managed by the National Marine Electronics Association. The processed data may be data obtained by extracting only some types of messages, such as RMC messages and GGA messages, for example. When a user presses the report button of the above-mentioned automatic speed enforcement device, it is preferable to send only coordinate values from GNSS or the like to the server instead of sending so-called raw data such as NMEA.

(8) The power consumption suppression means processes the acquired data so that the amount of data to be transmitted is smaller than the acquired data, and causes the communication means to transmit the processed data, and the acquired data It is preferable that the system has a function of transmitting the information as it is to the communication means.

It is possible to send not only processed data but also unprocessed data.
On the data receiving side, the received processed data is recorded on the blockchain, while the received acquired data is processed to be recorded on a predetermined server of a general database (relational database, etc., NoSQL database, etc.). good.

(9) The power consumption suppression means may be a system that processes acquired data acquired under a predetermined situation so that the amount of data to be transmitted is smaller than the acquired data, and transmits the processed data. .

Power consumption due to data transmission is suppressed under certain conditions.
The determined situation is preferably the situation shown in (4).

(10) The power consumption suppression means processes and processes the acquired data so that the amount of data to be transmitted is smaller than the acquired data, depending on the degree of the event detected in the target target device. It would be good to have a system that sends the subsequent data.

The degree to which the amount of data to be transmitted is reduced varies depending on the degree of the event detected in the target device.

The target device may be, for example, a vehicle, and the detected events may be the attitude, orientation, and position of the vehicle, an impact applied to the vehicle, pressure applied to the vehicle, temperature of the vehicle, and the like.

For example, when the system detects that the vehicle is in a predetermined attitude, such as upside down, the system processes the acquired data to the first level to reduce the amount of data and sends it. When it is detected that there is, it is preferable to process the acquired data to a second level, which has an even smaller amount of data than the first level, and transmit the processed data.

(11) The power consumption suppression means may be a system that transmits data corresponding to the acquired data when one or more events detected in the target device satisfy a predetermined condition.

Transmission of data according to acquired data is determined depending on whether an event detected in the target device satisfies a predetermined condition.

The target device is, for example, a vehicle and the driver of the vehicle, and the detected events include the posture, direction, and position of the vehicle, the impact applied to the vehicle, the pressure applied to the vehicle, the temperature of the vehicle, and the driver's alertness level. , eye open state, degree of opening of the eyes, number and speed of blinking, breathing rate, heart rate, etc.

For example, when the driver is determined to be drowsy as a result of detecting the driver's alertness level and an impact of more than a threshold value is applied to the vehicle, the system does not process the acquired data or After processing the data to a standard level, the acquired data itself or the processed data processed from the acquired data, that is, the data corresponding to the acquired data, is transmitted. For example, when the driver is detected to be falling asleep, looking away or looking aside, and the vehicle is subjected to an impact greater than a threshold, the system acquires a second level of data that is even smaller in amount than the first level. It is better to send the processed data after processing the data.
(12) The power consumption suppression means processes the acquired data based on information indicating the contract details of the LPWA of the user so that the amount of data to be transmitted is smaller than the acquired data, and It would be good to have a system that sends data.

The degree to which the amount of data to be transmitted is reduced varies depending on the user's LPWA contract details.

Information indicating the details of the LPWA contract may be stored and obtained, for example, in the manner shown in (6). The system may acquire information indicating the details of the LPWA contract and process the information so that, for example, the smaller the amount of data that can be communicated is restricted, the smaller the amount of data to be transmitted becomes.

(13) The power consumption suppression means transmits the acquired data so that the amount of data to be transmitted is smaller than the acquired data, the amount of remaining data that the user is permitted to transmit based on the contract details of the LPWA. It would be better to create a system that processes the data accordingly and sends the processed data.

The degree to which the amount of data to be transmitted is reduced varies depending on the remaining amount of data that the user is permitted to transmit based on the LPWA contract details.

Information indicating the details of the LPWA contract may be stored and obtained, for example, in the manner shown in (6). The remaining amount of data that the user is permitted to transmit based on the LPWA contract may be, for example, the remaining amount of data that the user is allowed to transmit based on the LPWA contract.

For example, if a user has an LPWA contract that allows a predetermined amount of communication on each monthly renewal date, the amount of data communicated up to that renewal date will be subtracted from the contracted monthly data amount. As the update date approaches, the amount of remaining data decreases. With this configuration, for example, when the remaining amount of data is low before the update date, the amount of data is processed so that it is smaller than when there is a surplus of remaining data. This makes it less likely that the remaining amount of data will run out compared to a system that does not have this configuration.

(14) The power consumption suppression means may be a system that adjusts an interval for searching for a transmission destination.

Power consumption is reduced compared to the case where the interval for searching for transmission destinations is not adjusted.

The communication means controlled by this system preferably has a function of searching for a transmission destination, and further preferably has a function of being able to adjust the search interval from the outside. Further, it is preferable that this system has a function of searching for a destination. Furthermore, it is particularly preferable that both the present system and the communication means controlled by the present system have the function of searching for a destination.
In particular, the power consumption suppressing means of the present system may adjust the interval at which the communication means searches for a destination.

It is preferable that the system has means for accepting instructions from the user, and forcibly restarts the search for the destination when the instruction from the user is received during the interval for searching for the destination.

(15) The power consumption suppression means may be a system that adjusts a time interval for stopping the search for a destination.

Power consumption is reduced compared to the case where the time interval for stopping the search for the destination is not adjusted.
The communication means controlled by this system preferably has the function shown in (14).
In particular, the power consumption suppressing means of the present system may adjust the time interval at which the communication means stops searching for a destination.

It is preferable that the time interval at which the communication means stops searching for a destination is the interval between timings that satisfy a predetermined condition. Examples of the above-mentioned predetermined conditions include conditions such as whether or not the engine is stopped. For example, LTE-M has a power saving mode (PSM). In the present system, when the engine of a vehicle is stopped, the radio wave search stop interval is preferably controlled to be longer than when the engine is started.

If you set the maximum time to stop the radio wave search, the radio wave search will start again after the maximum time has elapsed. Therefore, it is preferable that the present system has a function of stopping the radio wave search again at the maximum time if a base station is not found in the radio wave search after the maximum time has elapsed.

This system sets the radio wave transmission interval relatively short immediately after restarting the radio wave search after stopping the radio wave search for a predetermined period of time, and then increases the transmission interval as time passes. It is a good idea to perform such control.

(16) It is preferable that the system controls a communication means using a different communication method from the communication means.

Power consumption is reduced compared to when the communication means and the specific method communication means are operated at the same time. In particular, the power consumption suppressing means preferably has a function of switching between the communication means and the other type communication means.

Other communication methods include 3G, LTE, 4G, 5G, Wi-Fi, Bluetooth (registered trademark), DSRC (Dedicated Short Range Communications), Electronic Toll Collection System (ETC), and other non-LPWA communication methods. It is preferable to use a communication means that adopts this method.

Moreover, module replacement in basic technology edge computing Some edge-side devices for edge computing can have communication modules replaced. Therefore, it is preferable that the communication means of other systems be constructed so that they can be replaced with this system. This system has a function of detecting whether or not a replaceable communication method using another method is available, and the power consumption reduction means of this system determines whether or not a replaceable communication method using another method is available. It is preferable to have a function to switch between the means and the means. That is, this system preferably detects the type of communication module plugged into the edge-side device, and selects the communication destination and communication data according to the type of communication module. For example, if the communication method is not connected and the Wi-Fi module is connected as another communication method, this system will perform all communication including images and videos using the Wi-Fi module. In a state where no other type of communication means is connected and an LPWA module is inserted as a communication means, images and videos are preferably stored in local storage without being communicated. The system may transfer the stored information by the Wi-Fi module, for example, when the Wi-Fi module is connected.

Also, for example, when both an LPWA module and a Wi-Fi module are connected, while LPWA communicates information other than images and videos (data exceeding a certain amount of data), images and videos, etc. It is best to communicate using a Wi-Fi module.

Furthermore, for example, when using LPWA for on-vehicle equipment (car security, door locks, etc.), it may become completely unusable outside the service area. In particular, a situation may occur where the door could be locked when getting off the vehicle, but when getting on the vehicle, the connection is interrupted and the door cannot be unlocked, or even when the on-vehicle device is unable to send out-of-service notification to the user's handheld device (smartphone).

In order to prevent the system from falling into the above-mentioned state, it is preferable to provide a backup means of communication with the user's terminal (smartphone) using Bluetooth or the like. In other words, in the case of out-of-range/outage of LPWA, this system should use a backup communication means to notify the user of out-of-range/outage to the terminal held by the user, and ensure minimum use of functions. Here, the functions to be guaranteed may be limited to, for example, only door locking and unlocking among the plurality of functions that the backup communication means has. It is desirable that the establishment of communication using the backup communication means be transparent to the user.

Further, the present system may read out settings for a user to use other communication means from a server using a communication means based on LPWA, and supply the settings to the user's terminal, for example. In this system, by directly connecting the user's terminal to the Internet (server) via the LPWA base station, it is preferable that the terminal itself independently prepares the usage environment. As a result, the user does not need to configure connection settings for network-based products with complex functions, and the complexity of using the product is reduced.

(17) The communication means may be a system including a first communication means that communicates with a server device that stores data, and a second communication means that does not communicate with the server device.

Power consumption is suppressed compared to the case where the first communication means and the second communication means are operated at the same time. In particular, the power consumption suppressing means preferably has a function of switching between the first communication means and the second communication means.

As a server device that accumulates data, it is preferable to use a server device included in a cloud provided by, for example, SIGFOX.
The first communication means for communicating with the server device may be, for example, SIGFOX.
The second communication means that does not interact with the server device may be, for example, LoRa. It is preferable that the second communication means does not directly communicate with the server device using the LPWA communication method. The second communication means is connected to another network indirectly, for example, via a gateway device or the like that is included in the network formed by the second communication means and is connected to the other network using a communication method other than LPWA. It is preferable to include those that interact with the server device.

This system has a first communication means that communicates with the server device and a second communication means that does not interact with the server device, and includes, for example, a communication function between LoRa and cellular LPWA (for example, LTE-M), LoRa and Wi-Fi It has a combination of communication functions, etc.
Then, the present system acquires data from another device through communication using the second communication means, and transfers the data to a server on the Internet using the first communication means.

In this system, for example, a drive recorder equipped with a communication means using Wi-Fi is provided with a function such as remote control operation using LoRa, and the operation contents of the LoRa remote control are transmitted when connected to Wi-Fi. In this case, there will be a delay when Wi-Fi is not connected. Therefore, if real-time operation is required, it is preferable to use cellular LPWA instead of Wi-Fi. It is preferable that the LoRa communication device communicates with various sensors installed in LoRa in addition to the LoRa remote control, and transfers the acquired information to the server using a network connection function such as cellular LPWA.

(18) The communication means may be a system including a third communication means capable of handover communication and a fourth communication means not capable of handover communication.

Power consumption is suppressed compared to the case where the third communication means and the fourth communication means are operated at the same time. In particular, the power consumption suppression means preferably has a function of switching between the third communication means and the fourth communication means.

As the handover communication, for example, communication in which the base station communicating with the mobile station is switched while the mobile station is moving may be used.
The third communication means capable of handover communication may be, for example, LTE-M.
The fourth communication means that is not capable of handover communication may be, for example, LoRaWAN, SIGFOX, or the like.

The usage fee for the third communication means that is capable of a handover function tends to be higher than that of the fourth communication means that is not capable of handover communication. Therefore, this system determines whether the situation is such that there is a high possibility that a handover is not necessary, and when there is a high possibility that a handover is not necessary, the system uses the fourth communication means to When the probability is high, the third communication means is used.

It is preferable to determine whether the situation is such that there is a high possibility that handover is not necessary by detecting whether the position of the mobile object is moving. The present system may determine that the situation is such that, for example, when the position of the mobile object remains within a specific range, there is a low possibility that handover is necessary (that is, there is a high possibility that handover is not necessary). The specific range may be, for example, a radius of several tens of meters.

This system has a function that allows the user to recognize whether communication is being performed using a third communication means that allows handover or a fourth communication means that does not allow handover. Good.
The communication means includes a mobile communication capable communication means capable of communicating even when the vehicle is moving at a speed exceeding a predetermined speed, and a communication means capable of communication while the vehicle is moving at a speed exceeding a predetermined speed. It is recommended that the system be equipped with a communication means that cannot communicate with mobile communication.
In this way, it is possible to communicate while moving at high speed or while the vehicle is parked, and the amount of communication can be distributed to both communication means, so there is no limit to the amount of communication depending on the fee. It becomes possible to use LPWA services efficiently. The communication means capable of mobile communication may be, for example, ELTRES, and the communication means with difficult mobile communication may be, for example, SIGFOX.
The communication means may be a system comprising a GPS-required communication means that requires the use of GPS time information for communication, and a GPS-unnecessary communication means that does not require the use of GPS time information for communication.
In this way, it is possible to communicate indoors where GPS cannot be received, and also outdoors where GPS can be received, and the amount of communication can be distributed to both communication methods, so communication can be done according to the charge. It becomes possible to efficiently use LPWA services that have a limited amount. The communication means capable of mobile communication may be, for example, ELTRES, and the communication means with difficult mobile communication may be, for example, SIGFOX.
In addition, if a configuration is adopted in which communication is possible by switching between different communication methods, it is recommended that the server side record which communication method the data was received by associating it with the received data. If such recording is performed when recording data on a computer, it becomes easier to verify the reliability of the data and identify the origin of the data.

(19) The communication means may be a system having a function of using a SIM that is detachable from the communication means and a function of using a SIM provided within the communication means.

It is possible to control the SIM that is removably attached to the communication means and the SIM provided within the communication means according to their respective uses. In particular, the power consumption suppressing means preferably has a function of switching between a SIM that is removable from the communication means and a SIM provided within the communication means. Power consumption is reduced compared to when these SIMs are operated at the same time.

SIMs used in LPWA include a regular card-shaped SIM that is inserted into a slot, and a chip-type SIM that is soldered to a board. In addition to incorporating a chip-type SIM, this system may also be provided with a regular card-type SIM slot. This system uses a chip-type SIM for communication when no SIM is inserted in a regular SIM slot, while communicating using a chip-type SIM when a SIM is inserted in a regular SIM slot. It is preferable to give priority to the SIM inserted in the slot.

In addition, the above-mentioned ``function of switching between the SIM that is removable to the communication means and the SIM installed in the communication means'' is performed depending on whether the engine of the vehicle is running or not, or whether the vehicle is running. It is preferable that the switching destination is determined depending on the status or not. The state of the vehicle's engine and the running state of the vehicle may be estimated by detecting the occurrence of vibration and based on its degree. For example, this system may use a chip-type SIM when it is determined that vibrations occur, and use a normal SIM when it is determined that vibrations do not occur.

In addition, it is preferable that the above-mentioned function determines the switching destination depending on the temperature. For example, this system determines whether the temperature is high based on the measurement results of a thermometer, and uses a chip-type SIM when the temperature is high, and uses a regular SIM when the temperature is not high. .

Further, it is preferable that the switching destination of the above-mentioned functions is determined depending on the location of the communication means. This system may automatically switch which SIM to use depending on the location of the communication means specified by a positioning system such as GNSS, for example.

(20) having a first positioning means for measuring the position;
The communication means may include a second positioning means different from the first positioning means.

Information that cannot be obtained by the first positioning means can be obtained from the second positioning means. In particular, the power consumption suppression means preferably has a function of switching between the first positioning means and the second positioning means. Power consumption is suppressed compared to the case where the first positioning means and the second positioning means are operated at the same time. The second positioning means may provide information necessary for the communication means to communicate.

The first positioning means may be, for example, a positioning device using GNSS or the like built into a drive recorder, and the second positioning means may be, for example, a positioning device included in LTE-M, ELTRES, or the like.

For example, LTE-M has a positioning function. Therefore, it is preferable for this system to provide a positioning function other than this positioning function, and to have a function of selecting one of the two pieces of information as the information to be used. It is preferable that this system has a function that allows the user to set which positioning function to select by accepting operations, but it also has a function that automatically selects which positioning function to use by comparing the output data of both. It's good to be prepared.

(21) It is preferable that the system performs control to notify the user of the status of the communication means from the notification means.

The user can know the status of the communication means changing in the system.

The contents to be notified to the user include, for example, the last transmission time by the communication means that performed the intermittent transmission, information indicating the search state of the destination shown in (14) and (15), and the first information shown in (16). A system having a communication means and a second communication means, information indicating which one is used, and a system having a third communication means and a fourth communication means shown in (17), It is preferable to use information indicating which one is used.

The present system preferably has a function of informing the user whether or not the radio wave search is stopped so that the user can recognize it.
The present system preferably has a function of notifying information regarding the radio wave search interval in a way that the user can recognize.

The present system preferably has a function of notifying information regarding the transmission interval in a way that the user can recognize.

The present system preferably has a function of informing the user whether a chip SIM or a regular SIM is being used so that the user can recognize it.

(22) The communication means is a communication means attached to a mobile body that communicates with a fixed communication means that does not move, and the system transmits data received from the fixed communication means at a destination where the mobile body moves. good.

Power consumption is reduced compared to when data is transmitted using communication means other than LPWA.

Fixed communication means include, for example, LoRa, NB-IoT, and SIGFOX, which are fixedly connected to measuring instruments such as thermometers and hygrometers, acquire measured values from the measuring instruments, and transmit signals indicating the measured values using LPWA. The moving object may be, for example, a car (truck, taxi, motorcycle) used in the transportation industry such as rail transport, automobile transport, ship transport, air transport, etc., a railway, a ship, an aircraft, or the like.

In the system, for example, a communication means using LPWA may be attached to a mobile object such as a truck of a delivery company or a taxi of a taxi company. When a mobile object enters a predetermined range centered around the above-mentioned fixed communication means, the system causes the communication means attached to the mobile object to receive a signal transmitted from the fixed communication means, and the signal indicates It is preferable to store the data in a storage device. When a moving object such as a truck or taxi mentioned above enters a facility such as a business office or a rest area of a delivery company or taxi operator, the data stored in the storage device is transferred to a server device installed at that facility. You can transfer it to etc. With this configuration, for example, when a mobile object moves to an area where communication is difficult, measurement results from measuring instruments installed in that area can be collected.

To obtain information from IoT devices in areas with poor communication conditions, there are two ways to obtain information from IoT devices: the edge device and base station device communicate and the base station device connects to the Internet, and the base station device is not connected to the Internet and the edge device and base station device communicate with each other. There are devices that communicate with base stations and acquire data using base station equipment. Either device must be able to communicate between the two devices. However, for example, in mountainous areas, there are mountains and valleys that may prevent communication.

In this system, the above-mentioned LPWA communication means attached to the mobile body communicates with LPWA devices in areas with poor radio wave conditions or areas where base stations are not installed, acquires and stores information, and connects to the base station. It is preferable to transmit these pieces of information stored at the time of the call to a server or the like via the base station.

(23) A second system that transmits information to the system according to any one of (1) to (22),
a second power consumption suppression means for generating data so as to suppress power consumed by the communication means when the communication means receives data transmitted from the second system side to the system side; It is better to have two systems.

The power consumption when the communication means of the system according to any one of (1) to (22) receives data from the second system is lower than when the second system does not have the second power consumption suppression means. It becomes less.

As a method of controlling to suppress the power consumption, it is preferable to use a method equivalent to the methods exemplified in (2) to (22) performed by the power consumption suppressing means in the above-mentioned system.

Further, it is preferable that the second power consumption suppressing means generates a specific type of data whose amount of data to be transmitted is smaller than other types of data. The data generated by the second power consumption suppression means may be, for example, data for remotely controlling the system.

That is, the second power consumption suppression means of the second system is, for example, air conditioning equipment such as air conditioners, heaters, humidifiers, and air purifiers for residences and vehicles, vehicle starting devices such as vehicle engine starters, It is recommended to generate control signals as the data described above to remotely control control targets such as car security devices such as keyless entry systems, recording devices such as drive recorders, and various devices installed in residences, vehicles, etc. . When this second system is applied to a user's smartphone, this smartphone functions as a so-called remote controller.

The second system may be, for example, an on-vehicle device such as a drive recorder or a car navigation system provided in a moving body, and may be a system that transmits information to a system that controls communication means using LPWA.

When the second system periodically distributes POI data to a communication means controlled by this system, the second system does not transmit all of the POI data by LPWA, but rather, for example, transmits POI data posted by the user. It is preferable to distribute only the POI data based on LPWA using LPWA, and distribute other POI data using the above-mentioned other communication means that employs a communication method other than LPWA (such as Wi-Fi).

Further, the second system may select only POI data that satisfies predetermined conditions, such as POI data indicating the location of an automatic speed enforcement device, a traffic police officer, etc., and distribute it using LPWA.

Further, the second power consumption suppressing means preferably generates a control signal indicating the occurrence of an opportunity/trigger for starting or stopping driving in a controlled object such as a drive recorder, a surveillance camera, or an in-vehicle security system, as the above-mentioned data. .

(24) The second power consumption suppressing means may be a second system that generates data indicating a determination result of determining whether or not the target device can operate, based on the status of access from the system.

The communication means of the system according to any one of (1) to (22) receives less data than when receiving information other than the determination result.

For example, the second system may transmit the determination result to the second transmitting means as a control signal for the target device. The target device may be controlled by the system to prevent the target device from operating, regardless of the user's operation, when the communication means receives a signal indicating a determination result that the operation of the target device is prohibited.

The target device may be a mobile device that carries luggage or people, such as a car or motorcycle used by a taxi or delivery company.

In this second system, it is preferable that the target device accesses the server and performs procedures upon startup, and does not operate unless authentication is passed for a certain period of time. Furthermore, in the second system, if the server detects that the target device has been stolen, it is preferable that the authentication is not passed.

(25) The second power consumption suppression means may be a second system that generates data indicating a warning to a user attempting to operate the target device.

The amount of data to be transmitted is smaller than when transmitting data other than data indicating a warning.

The target device and the operation of the target device may be as shown in (23). The second system causes the user who intends to drive the vehicle to transmit identification information, such as data such as an image, character string, and voice, indicating a message prohibiting driving, or an index thereof, to the second communication means. Good.

(26) The second power consumption suppression means may be a second system that causes the communication means to transmit position data indicating the position of the target device, and generates the data based on the position data.

The amount of data to be transmitted is smaller than in the case of transmitting measurement data measured at the position of the target device for specifying the position.

The target device is preferably as shown in (24). Preferably, the second system stores the position data indicating the position of each vehicle, which is received by the second communication means, in a management device provided in a management center or the like to manage the positions of the vehicles.

A target device such as a drive recorder mounted on a vehicle acquires position data indicating the position of the device, measured by GNSS etc., in the above-mentioned NMEA format, but the position data is sent to the server in NMEA format. Then, for example, even if you limit the commands to GPMRC and GPGGA, it will take up a large amount of space in one hour. Therefore, it is preferable that the system communicating with the second system send only the coordinate values to the server instead of sending raw NMEA data, and it is particularly preferable to reduce the amount of communication by increasing the transmission interval of the coordinate values.

For example, when this second system, which includes a server that manages the dispatch of taxis, etc., receives a new dispatch arrangement that includes location data indicating the location of the smartphone from the smartphone of a customer seeking a taxi, it It is best to send the next destination to the target device (drive recorder, navigation system, etc.) of a nearby vehicle and instruct it to dispatch the vehicle. In addition to being used for taxis, this second system may be applied to bus operation management operations by bus companies, operation management operations for pizza delivery businesses, transportation industries, etc., police patrol operations using patrol cars, and the like.

With this system, for example, users can check where their vehicle is using a map app on their smartphone. This system does not always send coordinate values indicating the vehicle's position, but only when requested by an external device such as a smartphone or server. This saves communication traffic.

(27) The second power consumption suppressing means may be a second system that generates instruction data that instructs the surroundings of the target device to drive a notification device that notifies the existence of the target device. .

In order to make a user who has lost the location of a target device find the target device, the amount of data to be transmitted is smaller than when sending other than instruction data.

The target device may be, for example, a vehicle parked in a parking lot. The second system may cause the second communication means to transmit the instruction data, and when the communication means receives the instruction data, the system may drive a notification device that alerts the surroundings of the vehicle to the presence of the vehicle. As the notification device, for example, a lighting device such as a headlight, a tail lamp, or a fog lamp provided on the vehicle may be used. When the notification device controls a lighting device for the purpose of notifying people around the vehicle of the presence of the vehicle, it is preferable that the lighting device blinks in a predetermined pattern.

With this second system, for example, when a user loses track of where they parked their vehicle in a parking lot, they can make a request from their smartphone and the car's lights and sounds will be activated. This second system does not send coordinate values indicating the location of the vehicle to the smartphone, but rather drives the notification device. This saves communication traffic. By applying this second system, for example, if a mobile phone is not found, the user will be able to know the location of the vehicle etc. by calling the mobile phone and hearing the ring tone.

(28) It is preferable that firmware for operating the system and location data indicating one of the locations be transmitted as a second system separately from other data so that the fee is cheaper than other data.

Compared to the case where location data is not transmitted under the same fee structure as firmware, the charges incurred by transmitting location data are suppressed.

Systems such as in-vehicle equipment require "firmware" which is the basic software to operate themselves, and when the firmware is updated, the second system needs to send the updated firmware to each system. be. When sending firmware, the fee structure is often set so that it is cheaper (including free) than other data. When managing firmware update data communication, which is communication when updating firmware, and normal communication using different fee structures, the second system may include, for example, location information such as POI data in firmware update data. It is only necessary to include or attach the indicated position data and transmit it by LPWA in data communication for firmware update.

<Drive recorder functions>
The functions of the drive recorder 1, which is an example of the first system, will be described below.
The controller 11 of the drive recorder 1 functions as a "power consumption suppressing means" that controls the LPWA communication device 13 so as to suppress the power consumed.

As described above, the camera 18 captures an image of the driver's seat and outputs a video signal representing this image, and the controller 11 converts this video signal into video data and records it on the SSD 12. The controller 11 processes this video data as "unprocessed data".

Specifically, the controller 11 analyzes this video data and recognizes the positions and movements of the driver's neck, face, torso, arms, and other parts shown in the image. The system then determines the danger of the driver's driving based on the recognized positions and movements of each part of the driver.

For example, if it is recognized as a result of analyzing video data that the driver's neck is moving periodically depending on the timing of breathing, or that the eyelids are closing at a rate that exceeds a threshold, the controller 11 It is determined that the driver is drowsy at the wheel. Further, when 10 seconds have passed since the driver closed his eyes, the controller 11 determines that driving is dangerous.

When the controller 11 analyzes the above-mentioned video data and determines the danger of driving by the driver, it generates data indicating the determined result (determination result data) as "processed data", and the generated determination result. The data is transmitted to the server 2 by the LPWA communication device 13.

This judgment result data is data that indicates the result of comprehensive judgment by analyzing the content of the video data and comparing the movement and position of each part of the driver with predetermined patterns and thresholds, etc. The amount of information is smaller than the amount of information of video data.

Therefore, with the above-described configuration, the power consumed when the drive recorder 1 transmits data to the server 2 is suppressed compared to when the drive recorder 1 transmits unprocessed video data as it is. .

That is, the controller 11 processes the acquired data so that the amount of data to be transmitted is smaller than the acquired data, and transmits the processed data through the LPWA communication device 13, thereby implementing the "power consumption reduction means". ”.

As described above, the controller 11 of the drive recorder 1 functions as a "power consumption suppression means" that controls the LPWA communication device 13 so as to suppress power consumption. Therefore, the drive recorder 1 can further suppress power consumption in a system that controls communication means using LPWA, which generally consumes less power than communication using 4G or 5G.

<Modified example>
The above is the description of the embodiment, but the content of this embodiment can be modified as follows. Further, the following modifications may be combined.

<Modification 1>
The controller 11 of the drive recorder 1 described above processes the acquired data to reduce the amount of data before transmitting it, but by selecting the type of data to be transmitted from among the acquired data, the amount of data can be reduced. It may be possible to reduce the number of times.

That is, the controller 11 may suppress power consumption by causing the LPWA communication device 13 to transmit a specific type of data that requires a smaller amount of data to be transmitted than other types of data. In this case, the drive recorder 1 does not need to process the acquired data.

For example, when the drive recorder 1 acquires two types of data: continuous time-series data with a large amount of information and contact input (trigger information), the controller 11 selects the contact input without selecting the time-series data. It is preferable to transmit only the above information using LPWA. Contact input has a relatively small amount of information compared to time series data. The drive recorder 1 suppresses power consumption in communication by not sending time-series data with a large amount of information.

Further, the controller 11 may cause the LPWA communication device 13 to transmit identification information for identifying each data assigned to each of the plurality of data groups. Since the amount of identification information for each piece of data is smaller than each piece of data itself, this configuration suppresses the power consumed by LPWA communication.

Further, if there is data already transmitted by a communication means different from the LPWA communication device 13, such as the short-range communication device 10, the controller 11 transmits data other than the transmitted data to the LPWA communication device 13. You may let them.

<Modification 2>
The controller 11 may suppress power consumption by not causing the LPWA communication device 13 to transmit data indicating the video.

That is, the controller 11 may select character string data, contact input data, etc., and transmit the selected data using LPWA, without selecting video data. Video data representing images and videos (which may include audio) generally has a larger amount of data than other data representing character strings, contact inputs, judgment results, and the like. The controller 11 suppresses power consumption for communication using the LPWA communication device 13 by excluding it from transmission by the LPWA communication device 13 .

The data other than the video data may be, for example, data indicating the connection state between the drive recorder 1 and the smartphone 3, in addition to data indicating character strings, contact inputs, judgment results, etc. Moreover, data other than video data may be data that the drive recorder 1 receives from the smartphone 3 when the drive recorder 1 and the smartphone 3 are connected.

Note that the video data may be recorded on the SSD 12 and collected at a later date. Further, the video data may be sent to the server 2 via the communication line 6 from the smartphone 3 connected by short-range communication.

<Modification 3>
Even if there is data to be transmitted, the controller 11 may suppress power consumption by not causing the LPWA communication device 13 to transmit the data under certain circumstances.

For example, the drive recorder 1 described above includes a detection device that detects an object, and when the detection device detects an object, it causes the LPWA communication device 13 to transmit detection data indicating that the object has been detected. In other words, when the detection device detects an object is when there is data to be transmitted.

On the other hand, the drive recorder 1 described above, for example, uses the GNSS receiver 19 to measure its own position, that is, the position of the drive recorder 1 including itself, and specifies the current time and the position of the drive recorder 1. There is.

Only when the drive recorder 1 determines that the drive recorder 1 itself exists at a predetermined time and place, even if the detection device detects an object, the drive recorder 1 transmits the above-mentioned detection data to the LPWA communication device. 13 should not be sent. That is, under a predetermined situation in which the drive recorder 1 itself is present at a predetermined time and place, even if there is data to be transmitted, the data is not transmitted by the LPWA communication device 13.

<Modification 4>
The controller 11 may suppress power consumption by transmitting the acquired data at adjusted intervals. For example, the controller 11 may cause the LPWA communication device 13 to transmit position data indicating the position of the drive recorder 1 acquired from the GNSS receiver 19 at adjusted intervals.

The adjusted interval is an interval in which the number of times data is transmitted is smaller than the number of times the GNSS receiver 19 outputs data and the controller 11 acquires it. That is, the controller 11 adjusts the interval at which the LPWA communication device 13 transmits position data so that it is longer than at least the interval at which the controller 11 acquires position data from the GNSS receiver 19. The adjusted interval may not be constant.

<Modification 5>
The controller 11 may cause the LPWA communication device 13 to transmit the acquired data at intervals adjusted based on information indicating the user's LPWA contract details.

In this case, the SSD 12 stores information indicating the contract details of the user of the drive recorder 1. The controller 11 causes the LPWA communication device 13 to transmit the position data acquired from the GNSS receiver 19 at intervals adjusted based on the information indicating the contract details stored in the SSD 12. As a result, for example, compared to the case where all position data is transmitted, the power consumption is suppressed, and the degree to which the power is suppressed depends on the contents of the user's contract.

<Modification 6>
The above-mentioned controller 11 acquires and analyzes video data showing the image of the driver's seat captured by the camera 18 and stored in the SSD 12, and generates judgment result data indicating the result of judging the danger of driving by the driver. Then, this was sent to the LPWA communication device 13.

In other words, although the controller 11 processed the video data into judgment result data and sent it to the LPWA communication device 13, the amount of data to be transmitted is smaller than that obtained by using other methods. It is also possible to process the data as follows and send the processed data.

For example, the controller 11 may process the position data acquired from the GNSS receiver 19 so that the amount of data is reduced, and cause the LPWA communication device 13 to transmit the processed data.

For example, when the position data acquired from the GNSS receiver 19 is text data generated in accordance with standards such as NMEA0183 defined and managed by the National Marine Electronics Association, the controller 11 The data may be processed by extracting only some types of messages from this location data. Here, some types of messages include, for example, RMC messages and GGA messages.

Note that a configuration other than the controller 11 may perform the processing of processing the acquired position data so that the amount of data is reduced. For example, the controller 11 may entrust this processing to the controller 41 or the ECU 71. The controller 11 may receive the processed data generated on behalf of the user and cause the LPWA communication device 13 to transmit the processed data.

Furthermore, the danger of driving is not limited to what is determined based on the results of analyzing the video of the driver. The drive recorder 1 according to the present invention may include, for example, a device that detects in real time the tension of a belt or rope that tightens cargo on a truck. The controller 11 may predict the collapse of the load or the like based on the detected tension and judge the danger of driving.

Furthermore, the subject of judgment is not limited to the danger of driving. The object of judgment may be, for example, the safety of cargo based on temperature, humidity, illuminance, etc. during the delivery of refrigerated goods or animals.

Further, for example, the controller 11 acquires and analyzes video data representing a road video imaged by the camera 18 and stored in the SSD 12, generates judgment result data representing the analyzed results, and sends the data to the LPWA communication device 13. You may also send it. As a result of analyzing the video data, the controller 11 may determine, for example, the presence or absence of contact, deformation, or damage to the vehicle on the road, and the degree of such damage.

In this case, the subject of judgment is the presence or absence of a vehicle contact accident and its severity. Based on the acquired video data, the controller 11 extracts, for example, the contours of the car 7 and other vehicles, and specifies their respective positions in the video. Then, the controller 11 may recognize whether an accident has occurred by determining whether or not these vehicles are in contact with each other.

Further, the controller 11 may specify the type of event that has occurred based on the video data, and may transmit only identification information identifying the type of event to the server 2 using LPWA.

Furthermore, when an event such as an accident occurs, the controller 11 may cause the LPWA communication device 13 to transmit information regarding the occurrence of the event in addition to a code indicating the type of the event, without transmitting the video data. . Information related to the occurrence of an event is information that starts measurement when the event occurs, information that is extracted based on the occurrence of the event, and information that is analyzed based on the information that has been measured or extracted. Examples include information indicating results.

For example, the controller 11 may cause the LPWA communication device 13 to transmit behavior information indicating the driver's behavior measured for 20 seconds before and after the collision occurred. The behavioral information includes, for example, the direction of the driver's face, the direction of his line of sight, the open/closed state of his eyelids, and the amount of data is smaller than video data.

Further, the controller 11 may cause the LPWA communication device 13 to transmit information such as the acceleration detected by the acceleration sensor and the speed measured by the tachometer 74 at the time when the collision occurred.

Further, the controller 11 may cause the LPWA communication device 13 to transmit information indicating the position of the automobile 7 determined by GNSS or the like, vehicle behavior information indicating the behavior of the vehicle, and the like.

That is, the drive recorder 1 sends only "the fact that an accident has occurred", "the type code of the event that occurred", and "information regarding the occurrence of the event" together with the identification information of the drive recorder 1 to the server 2 by LPWA. Therefore, the drive recorder 1 suppresses the amount of communication compared to the case where video data or audio data itself is sent, and also suppresses the power consumption during communication.

<Modification 7>
The controller 11 has a function of processing the obtained data so that the amount of data to be transmitted is smaller than the obtained data, and transmitting the processed data to the LPWA communication device 13, and a function of transmitting the obtained data as it is to the LPWA communication device. 13 may also be provided.

For example, the controller 11 processes the position data acquired from the GNSS receiver 19 so that the amount of data is reduced. The controller 11 may have a function of transmitting the processed data to the LPWA communication device 13 and a function of transmitting the acquired position data as is to the LPWA communication device 13.

<Modification 8>
The controller 11 may process acquired data acquired under a predetermined situation so that the amount of data is reduced, and cause the LPWA communication device 13 to transmit the processed data.

Here, the determined situation may be a situation determined according to the degree of an event detected in the target device. For example, when the automobile 7 receives an external impact due to a traffic accident, the acceleration sensor 17 detects this impact.

Further, for example, when the automobile 7 rolls over or reverses due to an accident or the like, the acceleration sensor 17 detects the attitude of the automobile 7. For example, the controller 11 processes the position data acquired from the GNSS receiver 19 to reduce the amount of data, depending on the degree of the event such as an impact or posture detected in the automobile 7, and processes the processed data. It may also be transmitted by the LPWA communication device 13. In this case, the car 7 is an example of the target device.

Furthermore, when the degree of the accident is extremely large, the controller 11 may cause the LPWA communication device 13 to transmit video data. In other words, this controller 11 does not transmit large amounts of data such as video data in normal cases where the degree of the accident is not extremely large, and therefore the controller 11 transmits video data regardless of the degree of the accident. Reduce power consumption for communication.

Further, if the degree of the accident is greater than the threshold value, it may be clear that the automobile 7 is unable to drive and no further communication will take place. In this case, since there is no point in leaving a data amount that can be communicated by the LPWA communication device 13, the drive recorder 1 may transmit data with a large amount of data, such as video data, using the LPWA communication device 13.

By transmitting the video data, the user of the server 2 can easily determine whether an event such as an accident has actually occurred based on the video data. By making it easier to determine whether an event has actually occurred, it becomes easier to accurately determine subsequent arrangements.

This arrangement includes, for example, calling an ambulance, calling the police, etc. Furthermore, it may be known from the video data that the car 7 has fallen into water such as a dam. In this case, for example, the user of the server 2 can summon divers who have undergone underwater search training as a countermeasure.

Although the acceleration sensor 17 is a sensor that measures acceleration using a MEMS method, it may be a gyro sensor that measures the rotational angular velocity of the automobile 7, or a combination thereof.

Further, if the degree of the accident is extremely large, the controller 11 may increase the amount of data transmitted to the server 2 by the LPWA communication device 13.

Further, when the degree of the accident is extremely large, the controller 11 may transmit data to the server 2 via the communication line 6 from the smartphone 3 connected by short-range communication. Video data having a relatively large amount of data may be selected as the data transmitted from the smartphone 3 via the communication line 6. The smartphone 3 may connect to the drive recorder 1 by operating the short-range communication device 30 in the background, for example. For example, the smartphone 3 has a so-called tethering function that connects the drive recorder 1 to the communication line 6 such as the Internet by connecting to the drive recorder 1 using the short-range communication device 30 and connecting to the communication line 6 using the communication device 37. may have.

The smartphone 3 may include an acceleration sensor (not shown). The controller 31 of the smartphone 3 may start tethering and connect to the drive recorder 1 based on the impact detected by the acceleration sensor described above. The smartphone 3 connected to the drive recorder 1 may acquire video data and transmit the video data to the server 2 via the communication line 6.

<Modification 9>
The controller 11 may cause the LPWA communication device 13 to transmit data corresponding to the acquired data when one or more events detected in the vehicle 7 satisfy a predetermined condition.

For example, as a result of analyzing the first video of the driver, it was found that the driver was falling asleep with a probability of over 70%, and the measured impact force exceeds a threshold such as 5G. Suppose that the condition is satisfied. This impact force is measured by, for example, an impact force measurement device (not shown) provided in the drive recorder 1.

In this case, the controller 11 may cause the LPWA communication device 13 to transmit data corresponding to the acquired data. The data corresponding to the acquired data includes data indicating the analysis result of video data, data indicating behavior information of the driver, and the like.

As a result, for example, if there is a simple impact, data would be transmitted even if you just go over a step, but by transmitting data according to the combination of condition judgments of multiple events mentioned above, collisions can be more easily avoided. Data is sent only when there is a high probability that an event has occurred.

For example, when the drive recorder 1 acquires both detection data indicating that an automatic speed enforcement device or a traffic police officer has been detected by the machine, and report data indicating that the user has detected it, the drive recorder 1 receives the data. may also be sent. This increases the accuracy of detection by automatic speed enforcement devices and traffic police officers.

The drive recorder 1 according to this modification determines whether or not to transmit data by determining whether or not conditions are satisfied for one or more detected events. In comparison, transmission opportunities are narrowed down and power consumption for communication is suppressed.

<Modification 10>
The controller 11 may process the acquired data based on information indicating the user's LPWA contract details so that the amount of data to be transmitted is smaller than the acquired data, and may cause the processed data to be transmitted. .

For example, the controller 11 processes the position data acquired from the GNSS receiver 19 based on the information indicating the user's contract details (described above) stored in the SSD 12 so as to reduce the amount of data, and processes the processed data. It may also be caused to be transmitted by the LPWA communication device 13.

For example, the user may determine the type of data to be sent and the conditions for sending data, depending on the contracted amount of data that can be communicated per month.

<Modification 11>
The controller 11 processes and processes the acquired data according to the remaining amount of data that the user is permitted to transmit based on the LPWA contract details so that the amount of data to be transmitted is smaller than the acquired data. Later data may be transmitted.

For example, the controller 11 processes the position data acquired from the GNSS receiver 19 so that the amount of data is reduced according to the remaining amount of data that the user is permitted to transmit based on the above-mentioned contract details. The subsequent data may be transmitted to the LPWA communication device 13.

For example, in the case of a monthly contract, the remaining amount of data allowed for communication is maximum at the beginning of the month, decreases depending on the communication performance, and reaches the minimum at the end of the month. The conditions under which data is sent change according to the fluctuations in the amount of remaining data mentioned above, so for example, data that is sent when there is a lot of remaining data may not be sent when there is little remaining data. It may disappear.

<Modification 12>
The controller 11 may adjust the interval at which the LPWA communication device 13 searches for a destination to send data.

The LPWA communication device 13 controlled by the controller 11 of the drive recorder 1 preferably has a function of searching for a transmission destination, and further preferably has a function of being able to adjust the search interval from the outside. Further, it is preferable that the controller 11 has the function of searching for a destination. Furthermore, it is particularly preferable that both the controller 11 and the LPWA communication device 13 have the function of searching for a destination.
In particular, the controller 11, which is the power consumption suppressing means of this system, may adjust the interval at which the LPWA communication device 13 searches for a transmission destination.

It is preferable that the drive recorder 1 has means for accepting instructions from the user, and forcibly restarts the search for the destination when the instruction from the user is received during the interval for searching for the destination.

<Modification 13>
The controller 11 may adjust the time interval at which the LPWA communication device 13 stops searching for a destination to send data.

The time interval at which the search for a transmission destination of the LPWA communication device 13 is stopped may be an interval between timings that satisfy a predetermined condition. The controller 11 of the drive recorder 1 receives notification from the ECU 71 of the result of monitoring the state of the engine 72 of the automobile 7, for example. When the controller 11 receives a notification that the engine 72 has stopped, it is preferable to control the radio wave search stop interval to be longer than when the engine 72 is started.

The controller 11 may have a function of stopping the radio wave search again at the maximum time if a base station is not found in the radio wave search after the maximum time has elapsed.

Immediately after restarting the radio wave search after stopping the radio wave search for a predetermined period of time, the controller 11 sets the radio wave transmission interval to be relatively short, and thereafter increases the transmission interval as time passes. It is a good idea to perform such control.

<Modification 14>
The controller 11 described above controls the LPWA communication device 13 as well as the short-range communication device 10 whose communication method is different from that of the LPWA communication device 13. It is preferable to switch between the communication device 10 and the communication device 10.

This switching may be determined, for example, depending on the communication status of the LPWA communication device 13 and the short-range communication device 10, depending on the time zone, or depending on the size of data to be transmitted. It's okay to be hit.

In the above-described embodiment, the short-range communication device 10, which is an example of "other communication means", uses Bluetooth, but other communication means include 3G, LTE, 4G, 5G, and Wi-Fi. -Fi, DSRC, electronic toll collection system, etc. can be adopted.

Further, the short-range communication device 10 may be configured to be replaceable with the drive recorder 1. The drive recorder 1 has a function of detecting whether or not the replaceable short-range communication device 10 is available, and the controller 11 connects the LPWA communication device 13 and the short-range communication device according to the detection result. It is preferable to have a function to switch between 10 and 10.

For example, in a state where the LPWA communication device 13 is not connected to the drive recorder 1 and a Wi-Fi module is connected as the short-range communication device 10, all communications including images and videos can be sent via Wi-Fi. -Performed by Fi module.

On the other hand, when the short-range communication device 10 is not connected to the drive recorder 1 and the LPWA communication device 13 is connected, the drive recorder 1 does not communicate images and videos and stores them in the local storage SSD 12. It's a good idea to leave it there. It is preferable that the drive recorder 1 transfers the information stored in the SSD 12 using the short-range communication device 10, which is a Wi-Fi module, when the short-range communication device 10 is connected.

In addition, for example, when both the LPWA communication device 13 and the short-range communication device 10 are connected, the drive recorder 1 cannot communicate information other than images, videos, etc. (data exceeding a certain amount) using LPWA. On the other hand, images, videos, etc. may be communicated using the short-range communication device 10.

<Modification 15>
The LPWA communication device 13 of the drive recorder 1 described above may include a first communication means that communicates with the server 2 that stores data, and a second communication means that does not communicate with the server 2. In particular, the controller 11 of the drive recorder 1 preferably has a function of switching between the first communication means and the second communication means of the LPWA communication device 13. The first communication means for communicating with the server 2 may be, for example, SIGFOX. The second communication means that does not interact with the server 2 may be, for example, LoRa. The second communication means preferably has a function of communicating with the server 2 via the communication line 6.

<Modification 16>
Furthermore, the LPWA communication device 13 may include a third communication means that is capable of handover communication, and a fourth communication means that is not capable of handover communication. As the handover communication, for example, communication in which the base station communicating with the mobile station is switched while the mobile station is moving may be used. The third communication means capable of handover communication may be, for example, LTE-M. The fourth communication means that is not capable of handover communication may be, for example, LoRaWAN, SIGFOX, or the like.

<Modification 17>
The LPWA communication device 13 of the drive recorder 1 described above has a function of using a SIM that is removable from the device and a function of using a SIM installed in the device. may not be provided. That is, the LPWA communication device 13 does not need to have the on-chip SIM 133 shown by the broken line in FIG. In this case, the LPWA communication device 13 only needs to use a removable SIM.

<Modification 18>
Further, the LPWA communication device 13 does not need to be provided with a removable SIM inside itself. In this case, the LPWA communication device 13 only needs to use the on-chip SIM 133.

<Modification 19>
The drive recorder 1 described above had the GNSS receiver 19 as a first positioning means for measuring the position. Although the LPWA communication device 13 had a built-in GNSS receiver 131 as a second positioning means different from the GNSS receiver 19, the drive recorder 1 does not need to have the GNSS receiver 19. Further, the LPWA communication device 13 does not need to have the built-in GNSS receiver 131.

<Modification 20>
The controller 11 may perform control to notify the user of the status of the LPWA communication device 13 through notification means such as the display 15.

For example, the controller 11 determines the time when the LPWA communication device 13 last transmitted data, the search state of the destination, the reception strength of radio waves, and which one is in use when it has multiple communication methods. The display 15 may display information indicating each of the above. Further, the drive recorder 1 may notify the user of this notification by sound, light emission from an LED, or the like. Pictograms may be used for display.

<Modification 21>
The LPWA communication device 13 of the drive recorder 1 may communicate with fixed communication means that does not move. In this case, the controller 11 receives data when the vehicle 7 approaches the above-mentioned fixed communication means, and transmits the received data to the LPWA communication device 13 when the vehicle 7 approaches the server 2 after moving. The server 2 may also transmit the information. The fixed communication means mentioned above is, for example, LoRa, NB, which acquires measured values from measuring instruments such as thermometers, hygrometers, anemometers, rain gauges, seismic intensity meters, and illumination meters, and transmits signals indicating the measured values by LPWA. -It is recommended to use IoT, SIGFOX, etc.

As long as the drive recorder 1 is a moving object, it may be mounted on a truck, taxi, bus, etc. used in the transportation industry, in addition to the automobile 7, or may be mounted on a motorcycle, a motorized bicycle, a bicycle, etc. Further, the drive recorder 1 may be mounted on a railway, a ship, an aircraft, etc. used in the transportation industry such as railway transportation, ship transportation, and air transportation.

<Modification 22>
The communication line 6 may be, for example, a LAN (Local Area Network), a WAN (Wide Area Network), a combination of these, or a combination of these and the Internet.
Further, the communication line 6 may include a public switched telephone network (PSTN), an integrated services digital network (ISDN), or the like.

<Modification 23>
The drive recorder 1 and the car navigation system 4 may be connected to be able to communicate wirelessly.

<Modification 24>
In the embodiment described above, the drive recorder 1 and the smartphone 3 were communicably connected by Bluetooth (registered trademark), but for example, 3G, LTE, 4G, 5G, Wi-Fi, DSRC (Dedicated Short Range Communications) , an electronic toll collection system (ETC), or other communication means (other method communication means) that uses a method different from LPWA.

<Modification 25>
The above-mentioned LPWA communication device 13 can be used in addition to the above-mentioned “ELTRES” as well as “LoRa”, “LoRaWAN”, and “LTE-MTC” as long as it is a communication device that follows the LPWA method that performs relatively long-distance communication with low power consumption. ” “NB-IoT” “NB-Fi Protocol” “RPMA” “GreenOFDM” “DASH7” “RPMA” “Wi-SUN” “EnOcean Long Range” “Weightless-P” “SIGFOX” “LTE Cat.0” “LTE Cat.M1" etc. may be used.

<Modification 26>
Instead of or in addition to the SSD 12, the drive recorder 1 may have an insertion slot into which a removable medium such as an SD card for permanently storing data is inserted.

<Modification 27>
Although the video signal output from the camera 18 was recorded on the SSD 12, it may also be recorded on a removable medium such as an SD card. Further, the video data converted from the video signal may be sent to the server 2 when the drive recorder 1 and the server 2 are connected using a method other than LPWA, such as LTE or Wi-fi. In this case, the drive recorder 1 may send video data to the server 2 via the smartphone 3. The controller 11 of the drive recorder 1 preferably monitors the status of the camera 18 and sends information indicating this status to the server 2 via LPWA. The status of the camera 18 includes information such as temperature, exposure amount, whether or not the camera 18 is moving, and whether it is normal or not.

<Modification 28>
The short-range communication device 10 described above communicates using Bluetooth (registered trademark). That is, the above-described short-range communication device 10 is a communication means based on IEEE802.15.1, but is compatible with other standards such as wireless LAN system (IEEE802.11), ultra-wideband wireless system (IEEE802.15.3a). ), ZigBee (IEEE802.15.4), and close proximity wireless communication (ISO/IEC 10536, ISO/IEC 14443, ISO/IEC 15693, ISO/IEC 18092, ISO/IEC 21481, etc., and combinations thereof). It may be a device.

<Modification 29>
Instead of or in addition to the SSD 42, the car navigation system 4 may have an insertion slot into which a removable medium such as an SD card for permanently storing data is inserted.

<Modification 30>
The controller 11 of the drive recorder 1 described above functions as a "power consumption suppression means" that controls the LPWA communication device 13 to exchange information with the server 2 so as to suppress power consumption. In addition to or in place of this, the controller 21 of the server 2 suppresses the power consumed by the LPWA communication device 13 when the LPWA communication device 13 receives data transmitted from the server 2 side to the drive recorder 1 side. It may function as a "second power consumption suppressing means" that generates this data so as to do so.

In this case, the server 2 is a second system that sends information to the drive recorder 1. The controller 21 may use a method similar to the method by which the controller 11 of the drive recorder 1 described above functions as a power consumption suppressing means.

<Modification 31>
The system in the present invention is not limited to the drive recorder 1 as a monitoring system in a vehicle, but may be other devices. For example, in place of the drive recorder 1, the system according to the present invention may be a monitoring system for a vending machine, a gas meter, a water meter, or the like.

Further, for example, the system according to the present invention may be a home monitoring system that monitors a home. This home surveillance system uses a camera to photograph the door, and a controller analyzes the video to determine whether the door has been opened. Furthermore, the controller of this home monitoring system analyzes the above-mentioned video and determines whether or not the person who entered through the open door is a member of a previously registered family. Then, the home monitoring system preferably transmits these determination results to the server 2 using LPWA.

The server 2 may comprehensively judge these judgment results and send the judgment result to the house monitoring system using LPWA, such as "the risk of thief is 70%." Communication from the home monitoring system to server 2 and communication from server 2 to the home monitoring system are both performed by LPWA, and rather than sending the acquired data as is, the data is processed and selected before being sent. This reduces the power consumption required for communication.

<Modification 32>
The controller 21 of the server 2 may generate data indicating the determination result of whether or not the target device is operable based on the access status from the drive recorder 1.

For example, when the drive recorder 1 analyzes the video data and determines the danger of driving, it transmits judgment result data indicating the judgment result to the server 2 via the LPWA communication device 13. The server 2 may cause the LPWA communication device 23 to transmit a control signal for the vehicle 7 according to the acquired judgment result data.

For example, when the risk of driving exceeds a threshold value, the server 2 may transmit a control signal for prohibiting driving of the car 7 to the drive recorder 1 via the LPWA communication device 23. When the drive recorder 1 receives a control signal prohibiting this driving from the server 2 through the LPWA communication device 13, it is preferable that the drive recorder 1 transmits this control signal to the ECU 71 of the automobile 7 via the above-mentioned car navigation system 4, for example.

When the ECU 71 of the automobile 7 receives a control signal that prohibits driving, it is preferable to control the engine 72 and the transmission 73 to control each part of the automobile 7 so as to prevent the automobile 7 from driving regardless of the user's operation.

It is preferable that the drive recorder 1 accesses the server 2 and performs procedures at the time of startup, and instructs the ECU 71 to instruct the user not to operate the automobile 7 if the authentication does not pass for a certain period of time. Further, if the server 2 detects that the automobile 7 has been stolen, it is preferable that the authentication is not passed.

The car 7 may be a car used by a taxi, a delivery company, or the like, or another moving body that carries luggage or people, such as a motorcycle, a motorized bicycle, or a bicycle.

Further, if the determined driving risk does not exceed a threshold value, the drive recorder 1 may record the content of the determination or the information used for the determination in the SSD 12. This record may be used by the user as a so-called life log. In other words, by recording on the drive recorder 1 the content of judgments regarding the danger of driving or the information used for such judgments, the user can reflect on the content of driving, grasp one's own driving tendencies, and It can increase your motivation to drive safely.

<Modification 33>
The controller 21 of the server 2 may generate data indicating a warning to a user attempting to operate the target device.

For example, the control signal for prohibiting the driving of the car 7 that the server 2 sends to the drive recorder 1 may include data that instructs the user who is about to drive the car 7 to be warned. When the controller 11 of the drive recorder 1 receives this control signal, it performs control to prohibit driving of the automobile 7 and may display a warning on the display 15 to the person attempting to drive the automobile 7.

<Modification 34>
The controller 21 of the server 2 may cause the communication means to transmit position data indicating the position of the target device, and generate the data based on the position data.

For example, when managing taxi dispatch, the server 2 receives a new dispatch arrangement including location data indicating the location of the smartphone 3 from a smartphone 3 of a customer seeking a taxi. Then, the server 2 may transmit the next destination to the drive recorder 1 of the car 7 or the car navigation system 4 close to the location indicated by the location data, and instruct the vehicle to be dispatched.

Further, when the server 2 receives a request for position information indicating the position of the automobile 7 from the user's smartphone 3, the server 2 may send this request to the drive recorder 1 using the LPWA communication device 23. The LPWA communication device 13 of the drive recorder 1 receives this request from the server 2 and sends the position information indicating the position of the own device measured by the GNSS receiver 19 to the server 2 using the LPWA communication device 13.

The server 2 sends the position information acquired from the drive recorder 1 to the smartphone 3 via the communication device 27 and the communication line 6. The smartphone 3 then displays the position of the drive recorder 1, that is, the position of the automobile 7 equipped with the drive recorder 1, on the display 35 based on the sent position information.

Thereby, the user can check where his/her car 7 is located using the map app on the smartphone 3. In this system, the drive recorder 1 does not always send the coordinate values indicating the position of the car 7, but only sends the coordinate values when there is a request from an external device such as the smartphone 3 or the server 2, which saves on communication traffic. This reduces power consumption for communication.

<Modification 35>
The controller 21 of the server 2 may generate instruction data that instructs the surroundings of the target device to drive a notification device that notifies the existence of the target device.

For example, upon receiving this instruction data from the server 2, the controller 11 of the drive recorder 1 communicates with the ECU 71 of the automobile 7 via the car navigation system 4. Then, the controller 11 may instruct the ECU 71 of the automobile 7 to drive the lamp 75 to notify the presence of the automobile 7 in accordance with this instruction data. In this case, the car 7 is an example of the target device, and the lamp 75 is an example of the notification device.

<Modification 36>
The controller 21 of the server 2 controls the LPWA communication device 23 and transfers firmware for operating the drive recorder 1 and position data indicating one of the positions to another so that the fee is cheaper than other data. It may be transmitted separately from the data.

<Modification 37>
The program executed by the controller 11 of the drive recorder 1 is stored in a computer readable recording medium such as a magnetic recording medium such as a magnetic tape and a magnetic disk, an optical recording medium such as an optical disk, a magneto-optical recording medium, or a semiconductor memory. It may be provided in a stored state. Further, this program may be downloaded via a communication line such as the Internet. Note that various devices other than the CPU may be used as the control means exemplified by the controller 11 described above, and for example, a dedicated processor or the like may be used.

<Modification 38>
Further, the program executed by the controller 21 of the server 2 is executed on a computer-readable recording medium such as a magnetic recording medium such as a magnetic tape and a magnetic disk, an optical recording medium such as an optical disk, a magneto-optical recording medium, or a semiconductor memory. It can be provided in a state stored in . Further, this program may be downloaded via a communication line such as the Internet. Note that various devices other than the CPU may be used as the control means exemplified by the controller 21 described above, and for example, a dedicated processor or the like may be used.
<Another example 1>
For example, a taxi calling device equipped with an LPWA communication function, a taxi calling button, and a display is installed in a facility such as a pub. Taxis will be equipped with GPS and LPWA communication functions, as well as vacancy notification devices with vacancy buttons and display devices that can be operated by taxi drivers. The taxi calling device stores a different facility ID for each device, and when a press of the taxi call button is detected, the stored facility ID is wirelessly transmitted to the server using the LPWA communication function. The taxi's vacancy notification device has a button that is held when the vacancy button is pressed and when it is not pressed. The taxi ID, which is different for each taxi, is associated with the current location information from the GPS and sent to the server every minute (the server also has an LPWA communication function). The server stores the facility ID in association with the facility's location information, facility name, etc., and when the facility ID is sent to the server, the taxi company will be able to respond to the application running on the installed tablet. Then, the system sends a push notification of the location information of the facility, the facility name, the location information of a taxi that is within a predetermined range from the location of the facility, and that has transmitted location information within a predetermined period of time, and the taxi ID. When the tablet app receives this push notification, it displays the location of the taxi, the time the current location information was received, the location of the facility, and the time the facility ID was received on a map. The dispatcher at the taxi company looks at the displayed positions of the taxis, the locations of the facilities, and the respective reception times, and touches the taxi to be dispatched from among the displayed plurality of taxis. The tablet sends the taxi ID of the touched taxi to the server as the taxi ID to be dispatched together with the corresponding facility ID of the dispatch destination. The server uses the LPWA communication function to send the facility name and facility location information of the destination facility ID to the vacancy notification device of the taxi ID, and also sends the location information of the taxi with the taxi ID to the taxi calling device. Information on the expected arrival time calculated from the route and the location information of the destination facility is transmitted. When the taxi calling device receives this, it displays on the display the fact that the taxi is being dispatched and the expected arrival time. The vacant vehicle notification device of the taxi ID that receives the facility name and facility location information of the facility ID of the destination uses the received information to display the route to the facility of the destination on the display device, and also indicates that the vehicle is vacant. Releases the button from being held down.
In this way, a taxi requester can call a taxi with a single button. Facilities such as stores can simply install a simple device, which is smaller than a smartphone and does not require charging, near the cash register or waiting area. The taxi company will be able to learn about taxis near the customer and be able to deliver the taxi to the requested location.
It should be noted that the taxi calling device may be provided with a taxi recall button to similarly transmit a notification to the server that there has been a taxi recall. In addition, the taxi calling device has a function to input the number of taxis you wish to dispatch, and the information on this number is also sent.The server side sends a push notification to the app along with the information on the number of taxis, and the app also sends the information on the number of taxis. Alternatively, the number of taxis may be displayed on a map and the number of taxis corresponding to that number may be selected from the map. Furthermore, a function may be provided to display a list of press times of call buttons and to cancel a call button pressed by mistake. In this case, the information about the cancellation, the number of the cancellation target on the list, and the facility ID are sent to the server side, and the server side displays the cancellation on the map display based on this information. At the same time, if a taxi has already been dispatched, cancellation information is distributed to the taxi calling device and vacancy notification device. In response to this, each device should display a message to the effect of cancellation, and return the empty car button to the state in which it is pressed. Further, the server may be a blockchain server, particularly a blockchain that is shared by tablet apps of multiple taxi companies.
The LPWA communication function of the empty vehicle communication device installed in taxis is equipped with both an ELTRES communication module and a SIGFOX communication module, and it determines whether or not GPS can be received in an underground parking lot, etc., and selects either one depending on the situation. It is a good idea to perform a process to switch whether to communicate to the server side using the communication module.If you are in a situation where GPS cannot be received, use the SIGFOX communication module, and if you are in a situation where GPS can be received, use the ELTRES communication module to communicate. good.
For example, a so-called golf navigation system may be equipped with an LPWA communication function, and may have a function of transmitting information on the user's ball hitting position to the server side using the LPWA communication function. For example, on a golf course, a golf navigation has a function that notifies the user of the distance from the current position measured by GPS etc. to the pre-stored position of the pin of the hole on the course currently being played, and It is particularly preferable to have a configuration in which a location registration button is provided that is pressed by the user, and location information of the location where the location registration button is pressed is transmitted to the server using the LPWA communication function. Furthermore, it is preferable that at least one of the following functions is provided, and preferably all of the following functions are provided. It would be good to have a function to memorize the location registered using the location registration button. It would be good to have a function to memorize the location registered using the location registration button. It is preferable to send information about the location where the point registration button is pressed, which is transmitted using LPWA, in association with time information about the time at which the button was pressed. Transmission by LPWA may be performed immediately upon pressing the point registration button, but it may also be possible to send a cup-in by a button for inputting a cup-in instruction from the user, or by GPS. The position of the location registration button on the hole that was being played before the movement based on at least one of the following: the current position has been moved to the position of another pre-stored hole, or movement has been started It is especially good to send the information history all at once to the server side using the LPWA communication function. Furthermore, it is preferable to have a function of transferring the memorized position to another device such as a PC after playing, or a function of displaying the position on the hole corresponding to the memorized position along with a schematic diagram of the golf course.
Furthermore, it is preferable that a so-called radar detector is equipped with an LPWA communication function, and has a function of transmitting witness information such as enforcement from the user to the server side using the LPWA communication function. It is preferable to send the location information from the user where the post button was pressed to the server side along with the time information when the button was pressed using the LPWA communication function.
