Description

  The present invention relates to a technique capable of acquiring dynamic data of a work machine operating on the site at a remote location.

  Conventionally, for the convenience of users of work machines, a system for acquiring dynamic data of work machines operating at the work site from terminals such as remote maintenance centers and offices using a communication line has been proposed and operated. Has been. A system disclosed in Japanese Patent No. 30112256 (Patent Document 1) is one of them, as shown in FIG. 5, via a wireless communication line between a management unit 50 serving as a center and each work machine 51. In this system, the remote management unit 50 acquires the dynamic data of the work machine 51 at the site. Further, in this system, as shown in FIG. 6, it is possible to acquire the dynamic data by accessing the work machine 51 from the terminal 52 of the customer who is the owner of the work machine 51 or the portable terminal 53 of the service person of the store. It has become a thing.

In addition, by applying such remote management system data transfer, when the work machine moves outside the set area, the management unit sends an engine stop command to forcibly stop the work machine A system has also been proposed as Japanese Patent No. 3597772.
Patent No. 30112256 (0028 stage, FIG. 1, FIG. 7) Patent 35977772 (0008 steps)

  However, in the system of Patent Document 1, the controller for data transmission in each work machine is basically a mechanism that interlocks with the engine key switch. Therefore, while the engine of the work machine is stopped, a remote place is used. There was a problem that data could not be received. Although a mechanism that allows transmission during the timer start by holding the power supply for about 5 to 10 minutes after the engine key switch is turned off by a timer or the like is considered (see Patent Document 1, stage 0028), In many cases, the current position information and the latest dynamic data are desired even while the work machine is completely stopped, and such a recent request cannot be satisfied at all.

  Further, in the system of Patent Document 2, when the work machine engine is stopped and stolen outside the setting area (for example, transported to a truck or the like), warning data is not transmitted, so the management unit side Cannot detect the theft, and even if it is moved outside the setting area by driving the engine, if the engine is stopped outside the setting area, the work machine cannot receive a stop command from the management unit, preventing theft It may happen that the function of the above does not work.

  Furthermore, in the system of Patent Document 1, as shown in FIG. 6, data can be acquired by accessing the work machine from the customer terminal 52 or the serviceman terminal 53, so the work machine has an authentication mechanism for a plurality of connected persons. In addition to being complicated, the processing is complicated, and a plurality of accesses are allowed, and the security measures are also increased. Furthermore, the system mechanism becomes complicated and the operation becomes unstable, and the run cost burden also increases.

  The present invention was devised in view of the above problems of the conventional system, and can provide the latest data as much as possible when the user needs dynamic data, and the system mechanism is simple. In addition, it is intended to provide a technique that can prevent data leakage and can exchange data suitable for the convenience of the user.

For this reason, the work machine side dynamics data management device of the remote management system according to the present invention is the work machine side dynamics data management device of the remote management system in which the dynamic data of the work machine is acquired remotely by the communication means. after having to obtain power to operate the device from the battery directly to the storage unit of the communication means, to store the contact data management unit that can provide data to a plurality of users, and is transmitted from the management unit was saved any transmission start data, the control unit by checking the arbitrary transmission start data stored in the storage unit of the communication means, to the communication means, based on the contact data wherein It is characterized in that only the management unit transmits dynamic data.

Here, the dynamic data refers to all data related to the state of the work machine, such as operating state data (hereinafter also referred to as operating data), abnormal state data to be warned (hereinafter also referred to as warning data), and the like. The name is not particularly limited. The contact data refers to data of a communication connection destination that can transmit dynamic data such as a telephone number and a mail address of a management unit. Further, any transmission start data, the control unit, the data may be in any form as long as data can be confirmed that stored in the storage unit of the communication means.

  In the present invention, it is assumed that, for example, call instruction data from the management unit side is set as transmission start data, and that the data is stored in the storage unit of the communication means is set as a transmission start key. In that case, when the user intends to acquire the dynamic data of the work machine, if the management unit sends an acquisition request to the work machine side via the communication means, an acquisition request is sent to the management unit, In the dynamic data management apparatus according to the present invention, the command data is stored in the storage unit of the communication means, so that the control unit takes out the contact data from the storage unit to the communication unit using the storage of the data as a start key. After that, the management unit side is accessed and the requested dynamic data is transmitted. On the management unit side that has received the dynamic data, the received data is provided to the user who has requested the data by any means. Since the management apparatus according to the present invention obtains power directly from the battery, such data can be exchanged even while the work machine is stopped.

  In this invention, the dynamic data management device on the work machine side obtains power directly from the battery of the work machine, and even if the engine key switch is off, it operates as long as the main power is not turned off. Therefore, even when the work machine is not operating, when the user desires dynamic data, the data can be acquired through the management unit. Of course, since the work machine can voluntarily transmit the dynamic data to the management unit, it is possible to transmit various dynamic data while the work machine is stopped. This means that even if the thief transports the work machine with a truck, warning data (for example, position data outside the set area) can be sent from the work machine side to the management unit, preventing theft. Will also work effectively.

  In the management device according to the present invention, the destination of the dynamic data from the work machine side is only the management unit in which the contact address is set in advance. Therefore, the data is provided to the user from the management unit by an arbitrary means. If the configuration is adopted, data can be provided to a plurality of users by providing data only to the management unit. This means that compared to a system that receives direct access from multiple users and provides data to it, the system can be greatly simplified and the communication run cost can be kept very low, as the authentication mechanism is not required. Become.

  In addition, since data is exchanged only by a management unit for which a contact is determined in advance, the risk of information leakage is greatly reduced, and the construction cost required for security is extremely low.

  Specific embodiments of the present invention will be described with reference to the drawings.

The network line information processing unit 105 includes a Web server that manages a Web site, and exchanges data with the customer terminal 3 and the store terminal 4 through the Web site. In this embodiment, since the customer terminal 3 uses the Internet line network 6 and the store terminal 4 uses the intranet line network 7, the Web server is provided with a gate for each line to exchange data. The route is divided for each network 6,7. In addition, in order to make a request for obtaining predetermined data from the Web site, login with an ID and a password is a condition. For this reason, an ID and a password are given to a customer and a serviceman who are permitted to access.

  As shown in FIG. 3, the work machine 2 is provided with a dynamic management controller 20 that is a dynamic data management device that controls data exchange between the inside and outside of the machine. In the electrical system of this embodiment, a main power supply circuit directly connected to a battery (not shown) of the work machine 2 is formed, and the dynamic management controller 20 and the engine start circuit are connected to the main power supply circuit in parallel. Yes. Therefore, even if the engine key switch is turned off, the dynamic management controller 20 is in an operating state unless the main power switch (disconnect switch) is turned off. The above electric system may be in any other form as long as the dynamic management controller 20 is directly connected to the battery and the on / off of the controller 20 is not linked to the on / off of the engine key switch.

  The work machine 2 is also provided with a vehicle body controller 21 that controls various devices of the vehicle. Unlike the movement management controller 20, the vehicle body controller 21 is connected to an engine key switch circuit and interlocks with on / off of the key switch. The vehicle body controller 21 is connected to various devices 23 (engines, pumps, sensors, etc.), takes out predetermined operation data therefrom, and stores them in an internal storage unit. The behavior management controller 20 is connected to the vehicle body controller 21 via the in-vehicle network 22, and the operation data captured by the vehicle body controller 21 is captured by the behavior management controller 20 via the network 22 (specifically, Are taken in from the wired communication unit 202 described later and stored in the operation data storage unit 210). Depending on the model, there is a mode in which the vehicle body controller 21 is not installed. In this mode, the various devices 23 are connected to the dynamic management controller 20 (the input / output signal processing unit 207 in FIG. 3) to directly operate data. It may be imported.

  The activity management controller 20 includes an arithmetic processing unit 200 as a main control unit, a storage unit 201, a wired communication unit 202, a wireless communication unit 203, a position measurement unit 204, a date management unit 205, and a power control unit 206. And an input / output signal processing unit 207. The arithmetic processing unit 200 outputs a command to each of the constituent units 201 to 206 with respect to data exchange in the controller 20 or the like. The storage unit 201 stores operation data of the work machine, warning data, and setting data in which conditions serving as a command reference for the arithmetic processing unit are described. In this embodiment, a memory is assumed as the storage unit 201, but other storage means may be used. In the storage unit 201, the storage area is divided into three parts, that is, an operation data storage unit 210, a spontaneous transmission data storage unit 211, and a setting data storage unit 212 in accordance with data to be stored. The wired communication unit 202 performs data communication with another controller in the work machine (the vehicle body controller 21 in the present embodiment) via the in-vehicle wired network 22. The wireless communication unit 203 includes a wireless communication device that can use the mobile phone line network 5 and a memory, and performs data communication with the communication unit 101 of the management unit 1 via the mobile phone line network 5. In the memory, a telephone number (contact data) of the management unit 1 communication unit 101 is stored, and an area for storing a call e-mail from the communication unit 101 is set. The position measuring unit 204 includes a GPS receiver, receives a radio wave from the GPS satellite 8, and measures the current position. The date management unit 205 includes a clock means and a rechargeable battery, maintains date and time even when the main power is turned off, manages date and time data, and when the date / time set in advance by the arithmetic processing unit 200 is reached, the arithmetic processing unit 200 Output. The power supply control unit 206 controls on / off of the internal power supply.

  The storage of each data in the storage unit 201 is processed according to a command of the arithmetic processing unit 200, and the operation data is stored in the operation data storage unit 210 from the vehicle body controller 21 via the in-vehicle network 22. Also, if there is abnormal data that matches the conditions for issuing a warning in the operation data, it is also stored in the spontaneous transmission data storage unit 211 as warning data. When warning data is stored in the spontaneous transmission data 211, as will be described later, the arithmetic processing unit 200 transmits the warning data to the management unit 1 side regardless of the presence or absence of a call e-mail from the management unit 1. Command is output. These control instructions of the arithmetic processing unit 200 are based on the setting data stored in the setting data storage unit 212 of the storage unit 201, but the setting data to be updated are transmitted from the management unit 1 side, The data is stored in the data storage unit 212.

  Next, communication processing in the behavior management controller 20 will be described with reference to FIG.

  As long as the main power switch is turned on, the arithmetic processing unit 200 constantly checks whether the call e-mail from the management unit 1 communication unit 101 is received and stored in the memory (S1). ~ S8 loop). When the calling e-mail is transmitted, it is received by the wireless communication unit 203 and immediately stored in its own memory. When the checking processing unit 200 confirms the storage (S1), the wireless communication unit 203 retrieves the telephone number of the management unit 1 communication unit 101 from its own memory and makes a call to the management unit 1 side (S2). ). When the wireless communication unit 203 communicates with the management unit 1 communication unit 101, if there is setting data from the management unit 1 communication unit 101, the setting data is transmitted, and a transmission request of the desired work machine 2 is transmitted along with it. The arithmetic processing unit 200 first checks whether or not the setting data has been received (S3), and if received, saves the setting data in the setting data storage unit 212 of the storage unit 201 and updates it (S4), and the result of the completion of the update Is returned to the management unit 1 as data (S5). As described above, the setting data is a control command of the arithmetic processing unit 200, and after the update, control is performed based on the updated setting. Next, the arithmetic processing unit 200 confirms the operation data request (S6), extracts the operation data of the desired work machine 2 from the operation data storage unit 210, and transmits it from the wireless communication unit 203 to the management unit 1 communication unit 101. (S7: On the management unit 1 side that has received the operation data, the data is reflected on the Web site and information is provided to the user). Next, the arithmetic processing unit 200 confirms the presence or absence of warning data in the spontaneous transmission data storage unit 211 of the storage unit 201 (S10), and if there is warning data, retrieves the data and manages it from the wireless communication unit 203. 1 Transmit to the communication unit 101 (S11: On the management unit 1 side that received the warning data, the data is reflected on the website and the user's mobile phone 30, 40 registered on the management unit 1 side is warned. Send an email to the effect that data has been received). The arithmetic processing unit 200 forcibly disconnects the line when a predetermined time has elapsed after each data transmission (S12, S13). When there is no e-mail for calling from the management unit 1 communication unit 101, the arithmetic processing unit 200 always checks whether there is warning data in the spontaneous transmission data storage unit 211 of the storage unit 201 (S8), If there is data, the wireless communication unit 203 makes a call to the management unit 1 communication unit 101 (S9) and transmits warning data (S11). The subsequent processing is the same as above (S12, S13).

  It is assumed that the customer terminal 3 and the customer mobile phone 30 are both in an environment in which a Web site operated by the management unit 1 can be accessed via the Internet network 6. Further, the customer mobile phone 30 has a function of receiving and storing e-mails.

  It is assumed that the store terminal 4 and the service person mobile phone 40 are both in an environment in which a Web site operated by the management unit 1 can be accessed via the manufacturer-affiliated intranet network 7. Further, the customer mobile phone 40 has a function of receiving and storing e-mails.

  Next, an actual data flow including the user of the remote management system configured as described above will be described.

  When a customer or a dealer service person who is a user wants to know the current operating status of his / her work machine 2, the customer terminal 3 or the dealer terminal 4 from the customer terminal 3 or the dealer terminal 4 through the Internet network 6 or the intranet network 7 respectively. Then, after accessing the Web site operated by the management unit 1 and logging in with an ID and a password, a request is made to obtain operation data of a desired work machine 2. On the management unit 1 side, the requested access data to the desired work machine 2 is obtained from its own database 103, and on the basis of the data, a call e-mail is sent to the desired work machine 2 via the mobile phone network 5. Send. On the work machine 2 side, the call e-mail is received by the wireless communication unit 203 of the activity management controller 20. When the arithmetic processing unit 200 of the controller 20 confirms the saving of the calling e-mail, it outputs a call command to the wireless communication unit 203 and makes a call to the management unit 1 side via the mobile phone communication network 5. Upon receiving the call, the management unit 1 side outputs an operation data request signal, and in response to this, the work machine 2 side obtains desired operation data from the storage unit 201 in the controller 20 Then, this is output from the wireless communication unit 203. Upon receiving this data, the management unit 1 side temporarily stores it in its own database 103 and reflects it on its own Web site in a predetermined output format. Thereby, the desired operation data at that time is displayed on the customer terminal 3 or the store terminal 4.

  In this flow, since the dynamic management controller 20 of the work machine 2 is operating even when the engine key switch is off, it is in a posture to constantly monitor and respond to the call e-mail from the management unit 1 side. As long as the main power switch is not turned off, the customer or the store serviceman who is the user always requests and obtains real-time operational data about the desired work machine 2 through the website operated by the management unit 1 It is possible to do. In addition, if the warning data is stored in the spontaneous transmission data storage unit 211, it is immediately transmitted from the work machine 2 side to the management unit 1 side as long as the main power switch is on, and the customer and service are transmitted by e-mail. Because it is communicated to the man, it can be known in real time that the work machine 2 is abnormal. In particular, when the work machine 2 moves out of the assumed area using GPS position information, the position information is stored as warning data, so that the user can immediately determine whether or not the theft is at a remote location. It can also be done. In the case of dynamic data that can be assumed to have a high possibility of theft, if the start control mechanism such as shutting off the engine start circuit is provided by the dynamic management controller 20 itself, thief prevention can be thorough and more useful. It becomes the composition.

  In addition, all operation data requests from the customer terminal 3 or the dealer terminal 4 are routed through the management unit 1, so that the work machine 2 sends only the operation data to the management unit 1. Since the start of data transmission is limited to the presence or absence of a call e-mail from the management unit 1 side, the user authentication mechanism for passing data is completely unnecessary for the work machine 2, and when it is accessed Rather than passing data, the call is terminated by the call, and then it is a process of sending data from the work machine 2 side to the management unit 1 where the connection destination is set. Both 2 and the management unit 1 have no risk of data leakage for a simple system mechanism.

  In addition, since the management unit 1 performs batch exchange of data with the work machine 2 and reflects the received data on the website and provides it to the user, only the numerical value from the work machine 2 is generated. By processing and displaying data in a format desired by the user, the system is suitable for the convenience of the user.

  In addition, the management department 1 can exchange data in a batch, so that it is possible to sort out operational data that is necessary for maintenance management and that required by the customer, which is necessary for each customer and dealer serviceman. Can provide only the right data.

  Also, the management unit 1 side collects operation data of all work machines at a fixed time (instructs data request for all work machines on a regular basis) and reflects the data on the website. However, in such an aspect, the communication cost is significantly reduced.

  The present invention is a technique applicable to remotely managing the operating state of a work machine.
