JP 2005-80403 A JP2012-220397

With the development of wireless communication technology and sensor technology, various measuring devices will be installed and spread rapidly in the future, and the participation of private companies in the agricultural field will be promoted. It is predicted that many measurement systems, mainly private businesses, will be popularized from closed measurement systems, and the measurement information service business that handles measurement information and business measurement information are shared among businesses, providing higher added value. Businesses that provide information services will be activated.

  In the present invention, measurement information is centrally managed, various measurement information is analyzed, and a high-value-added measurement information service can be provided, and a new information service business is developed by mutual exchange of analysis information. To make it easier. In addition, a measurement device that can be driven by a battery is provided to facilitate installation of the measurement device.

  Information from measurement devices is centrally managed by the server, and analysis software for measurement is executed on the server. On the server, various analysis and management software corresponding to the measurement purpose runs and provides analysis and management results to measurement operators and users.

  To the measurement device, a code indicating a measurement type indicating what measurement is to be performed is provided after being classified into a classification system, and at the same time, a code indicating a business owner that owns the measurement device is provided after being classified into a classification system.

  By using the PHS communication method as the wireless communication method of the measuring device, the battery life can withstand the use of 1 year at the shortest and 10 years at the longest. Of course, the communication method is not limited to PHS, and 3G, 4G mobile phones and Wi-Fi can also be used, and may be wired (such as USB).

The degree of freedom of the installation location of the measuring device is increased, and the communication method can be selected while judging whether the location where the commercial power source can be used, the location where it cannot be used, or the location where it is difficult to frequently visit the location. Measurement information analysis and management is performed by software of the measurement data center (server), and the measurement information itself or processing information information service that analyzes and manages measurement information, as well as multiple measurement device information and multiple analysis software Software, sharing of multiple analysis results, and comparative analysis with past measurement data are facilitated, and it becomes easy to provide high value-added information services.

It is a figure which shows the whole block diagram of this invention. It is a figure which shows the internal structure of a measurement device. The signal structure of a communication signal is shown. It shows the classification of measurement sensors.

  The present invention will be described below with reference to the drawings.

  FIG. 1 is an overall configuration diagram of the present invention. 81, 82, 83, and 84 are measuring devices that measure information such as rainfall, air volume, temperature, atmospheric pressure, and radiation dose.

  As shown in FIG. 2, the measurement device includes a measurement sensor 101, a signal generation unit 102, a wireless communication unit 103, an overall control unit 104, a GPS sensor 105, a clock 106, and a battery 107. The output information of the measurement device is measurement data including measurement sensor information and information associated with the measurement sensor described later. The wireless method of the measurement device should be selected considering whether the environment where the measurement device is installed can use a commercial power supply, can be powered by USB from a PC, has a WiFi environment, or can use Bluetooth. However, the public wireless communication network is highly versatile. In the case of a public wireless communication network, the battery life is improved by using a PHS having a low output power, and there is an example in which a battery life of 10 years is possible with a commercial measuring device.

  Referring to FIG. 1, measurement data is sent to a measurement data center 90 via a public wireless communication network 60 such as 3G, 4G, or PHS. The measurement data center 90 includes a measurement data accumulation unit 50, and all measurement data is collected here. The measurement information discriminating unit 51 discriminates what kind of measurement information (rainfall amount, radiation dose, etc.), information of a measurement operator, and the like from the accumulated measurement data. Some measurement operators perform their own information analysis as long as they receive measurement data. For this reason, the measurement information discriminating unit 51 can extract information on the business operator, and can distribute only the extracted information, that is, measurement data owned by the business operator to the business operator. The data center function of the business that performs information analysis by itself is shown in the self business server 91, and the self business server 91 is composed of the information analysis software 30 and the user information creation unit 20. ing. In the measurement data center 90, measurement data is processed by various data processing software 31, 32, 33 that performs data analysis / analysis and tabulation management based on the measurement data, and a desired measurement result is obtained.

  Take, for example, rainfall measurement. Currently, meteorological observations by the Japan Meteorological Agency are installed at 1300 locations nationwide with meteorological radars, which perform weather forecasts and disaster forecasts using a system called AMeDAS that observes meteorological data such as rainfall. Even though AMeDAS, which is installed at 1,300 locations nationwide, it is desirable to install a greater number of landslide disasters caused by heavy rain today.

  In the present invention, an example of facilitating further installation and observation will be shown.

  A measurement device 81 for measuring rainfall is installed at a necessary location, and rainfall data is collected in the measurement data accumulation unit 50. The rainfall information analysis / aggregation management software 31 is based on GPS information and rainfall information included in the measurement data. The rainfall information between the adjacent measurement points where the measurement device is not installed is estimated and calculated, and rainfall information is created, and the result is passed to the operator 21. For example, if the user is requested by the user to request rainfall data for only a certain village, the measurement operator 21 supplies the user with data for that village. The measurement period of measurement data may be set by setting period information in the measurement device and automatically transmitting measurement results from the measurement device for each measurement period. Let's take it too. Furthermore, there is also a method of automatically transmitting only when the measurement result changes more than a predetermined value. The method to be selected may be selected in consideration of the entire traffic based on the processing capacity of the measurement data accumulation unit 50 and the number of measurement devices. In addition, when the measurement operator wants to change the rainfall measurement cycle, the changed cycle is communicated to the rainfall information analysis / aggregation management software described above, and the rainfall information analysis / aggregation management software communicates to the measurement device. At the same time, the operation parameters of its own analysis work are changed.

  In particular, from the viewpoint of disaster prevention due to heavy rain, when a heavy rain forecast is issued, a rain measurement device is temporarily installed in a mountainous area adjacent to a landslide hazard area, and if the rainfall exceeds a certain value. A method of automatically issuing evacuation instructions to residents is also possible. This system is effective in preventing disasters in the Hiroshima area that occurred in August 2014. In such a case, the demand for rainfall measuring devices will be temporary, so the rental business will be activated.

  Some of the measurement data includes camera information that measures traffic, but software that is used to extract a car for traffic measurement from the camera information, that is, image processing that determines a car from a video signal. Since it is difficult to discriminate in real time only by processing, the image processing is performed by the image analysis engine 40. The measurement information discriminating unit 51 determines whether or not the information requires image processing. The information determined to be necessary is sent to the image analysis engine 40 and then processed by the traffic volume grasping management software 33. For example, camera information taken at an intersection, in FIG. 1, the signal of the measurement device 83 is analyzed by the image analysis engine 40, and there are three four-wheeled vehicles, four two-wheeled vehicles, and one bus. Output. Using this output, the traffic volume management software 33 combined with GPS information, at a certain intersection, at a certain time, three 4-wheeled vehicles, four two-wheeled vehicles, and one bus passed. And report the results. The measurement company 22 provides and distributes traffic information of intersections to users in each region. The image analysis engine 40 can also analyze and determine a four-wheeled vehicle as a taxi from the shape of the roof of the vehicle, and can also analyze the traveling speed of the vehicle.

  Since the rainfall information analysis does not require processing by the image analysis engine 40, the rainfall data of the measurement device 81 is guided to the rainfall information analysis / aggregation management software 31 as it is. When the measurement device 82 is an audio signal for noise or abnormal sound analysis, the spectrum of the signal from the measurement device 82 is analyzed by the spectrum analysis software 32. The analysis result is sent to the measurement business operator 22 that needs the analysis.

  The measurement operators 21, 22, and 23 are based on the processing result information by the data processing software 31, 32, and 33 that performs analysis, analysis, aggregation, and management of measurement data. The information is processed into necessary information for a user using a peripheral device and distributed to each user's device (mostly a personal computer or tablet) 10, 11, 12, 13, 14 via the Internet communication network 70. Some measurement operators may request information processing for users from a measurement data center operator. At this time, information processing for the user is performed in the measurement data center 90 and information is directly distributed from the measurement data center 90 to the user device.

  Each user or business operator may request the measurement device to change the measurement parameter while viewing the result information. In that case, the communication procedure (not described here) is defined separately. Therefore, a parameter change request signal is generated from the user's or operator's equipment. This request signal is sent from the measurement data accumulation unit 50 to the corresponding measurement device.

  For example, a request for changing the shooting angle or zoom ratio of the camera is sent to the measurement device 83, or information for changing the microphone sensitivity is sent to the measurement device 82.

  When a measurement provider provides wave height information to surfing enthusiasts, the measurement device 84 measures the wave height data of the surfing spot, and from the camera information, shows how many surfers are currently enjoying surfing at that spot. Based on the result of analysis by the analysis engine 40, GPS information and the like are added and sent from the measurement data center 90 to the operator. The operator distributes the information to the user. At that time, video can be taken at a surfing spot, and the video information can be attached by the operator's equipment to increase the added value to the measurement information.

  The wireless communication unit 103 in FIG. 2 not only transmits measurement sensor information but also receives a signal from the measurement data accumulation unit 50 in order to accept a change request from a user or a business operator, and receives the reception result from the overall control unit 104. , The overall control unit 104 changes the operation parameter of the measurement sensor 101 and also transmits the changed parameter value to the signal generation unit 102 to create a communication signal to be sent to the center.

  FIG. 3 shows a frame structure of a communication signal between the measurement devices 81, 82, 83, 84 and the measurement data center 90.

  The measurement center code is a code given to a business operator who operates the measurement data center 90. Similarly, the measurement company code is a code given to a rainfall measurement company or a traffic measurement company that provides measurement information services.

  The measurement company code is a country code (a code corresponding to the country name of the company), a domestic company classification code, a code corresponding to the company name, and a measurement managed by the company with the device manufacturer for measurement. It consists of the device model code (code corresponding to the product name) and serial number (measurement device serial number). The reason why the country code is provided is that this system can be used regardless of the country and is expected to spread all over the world. A system like AMeDAS of the Japan Meteorological Agency is used in Japan for weather forecasting, but in countries that do not have a system like AMeDAS, a weather forecasting system like the present invention is constructed and operated as a weather forecasting system. It is also possible to go.

  As will be described later, the measurement type code is a signal that systematically classifies the measurement target and indicates what measurement data.

  As described above, the sensor parameter is an operation parameter unique to the measurement sensor.

  GPS information and measurement time indicate the location and time at which measurement data is generated.

  Note that the measurement center code, measurement company code, and measurement type code are created, maintained, and managed by the code management unit 52, and the code information for all measurement devices is measured before the measurement device starts operation. It is distributed from the data accumulation unit 50. Of the communication signals between the measurement data center 90 and the measurement device, the measurement center code, the operator code, and the measurement type code are created by the code management unit 52, and the measurement cycle and the sensor parameters are the measurement operator, Created from a measurement result user or data processing software, the measurement data accumulation unit 50 formats the communication signal shown in FIG. On the other hand, GPS information, clock information, and measurement data are created by a measurement device, and a communication signal is formed by a signal forming unit of the measurement device.

  The measurement cycle is set to 1 hour, 12 hours, 1 day, 1 week, and the data measured in that cycle is automatically transmitted from the measurement device to the measurement data accumulation unit 50. As described above, the measurement data accumulation unit When data collection from 50 to the measuring device is performed by the polling method, the measurement cycle value is set to “0”. In addition, when automatic transmission is performed from the measuring device only when the measurement result is greater than or equal to a certain value, certain values are set to “#N” and a numerical value N beginning with # based on the request of the operator or user. This is done by sending it to the device.

  As the present invention becomes widespread, there are cases where the number of measurement operators increases and the code system of the operators is reviewed, or the measurement business is started, but the business is stopped for some reason and the measurement device is transferred to another operator possible. In such a case, the operator code needs to be rewritten to the measuring device. At that time, the code management unit 52 generates change information, sends a change signal from the measurement data accumulation unit 50 to the measurement device, and the measurement device rewrites the data of the signal generation unit 102 from the received change signal. Although not shown, the signal generation unit 102 has a flash memory, in which a measurement operator code, a measurement data center operator code, measurement type information, and sensor parameters are stored, and can be rewritten whenever necessary. It is.

  FIG. 4 shows an example of the type classification of the measurement sensor. Airflow and rainfall can be measured with a single measurement sensor, but traffic volume, human movement, etc. are measured by image analysis of camera information. In the above-described measurement type code assigned to the measurement device for measuring rainfall, the major classification is set as weather, and the minor classification is set as rainfall. In the centralized measurement system according to the present invention, as the demand expands, the number of types of measurement devices increases, and it is fully possible that measurement devices that were not assumed at the beginning of the business will appear. A review is required. In FIG. 4, only examples of major classification and minor classification are shown, but the classification system will be reconsidered with a three-layer structure of major classification, middle classification, and minor classification. With the reconsidered classification system, even if the measurement type code is changed, the code management unit 52 can send new measurement type information to each measurement device and rewrite the code of the measurement device.

  In FIG. 1, four types of measurement devices are described as examples. Actually, since various sensors shown in FIG. 4 and many of the same sensors are installed, actually, much more sensor information includes measurement data. Information is terminated in the accumulation unit 50. Information of the measurement data accumulation unit 50 is stored in the measurement data history management unit 53 every time data is generated as shown in FIG. The stored data becomes an enormous database, and is used not only for history management but also for analyzing the difference between the current measurement data and past data together with the history search / analysis software 54. The supply itself may be required by businesses and users. For example, provision of rainfall data at a certain point in the past can be a business.

  It is also used for failure diagnosis of measuring devices. The failure diagnosis of the measurement device is performed by the failure diagnosis software 55. When measurement data cannot be taken from the measurement device (cannot communicate with the measurement device), the signal generator 102 is requested to rewrite the data. When the request is not reflected in the measurement data read by the measurement data accumulation unit 50, a failure is diagnosed, but when the measurement data itself seems abnormal, the data history management unit 53, history search / analysis software While referring to the past data history together with the wear 54, whether or not the data has occurred in the past will be judged to determine the anomaly of the data. By managing the failure diagnosis result of such a measurement device also by the measurement data history management unit 53, statistical management data such as which device of which operator has many failures can be created, which is useful for failure prediction. . In this case, the serial number included in the measurement company code will be useful information for the manufacturer of the measurement device.

  1 shows three examples 21, 22, and 23, but in reality, many operators deliver information to users based on the measurement information as shown in FIG. 4.

  Depending on the measurement provider, it is also possible to use a plurality of application result information to provide a composite measurement information service. For example, the information accuracy of the weather information provider can be improved by linking the wave height information provided by the surfing information provider with the information on the rainfall and wind volume owned by the weather information provider.

  For golf enthusiasts, the golf course wind information is useful, and the golf course installs an air flow meter for each hole and measures the current wind strength and direction. By linking rainfall information to this information, it becomes possible to provide more useful information to golf enthusiasts.

  Also, link rainfall information and traffic information to analyze the relationship between rain and traffic, so that at certain intersections, you can see the causal relationship that traffic in this direction increases in this direction during rainy weather. If it becomes, control, such as changing the period of a traffic signal according to it, will also become possible.

  Although only three examples of the data processing software in FIG. 1 are shown, actually, data processing software is prepared for each measurement target in FIG. In addition, software for analyzing and creating new information using analysis results of a plurality of software is also prepared.

  The present invention also contributes to improving the convenience of the electronic measuring instrument. It is inconvenient to transport a measuring instrument that weighs more than 10 kilograms. However, if the probe function of the measuring instrument is used as a measuring device and the main unit function is implemented as analysis software in the measurement data center 90, the user of the measuring instrument Just carry the probe, and a user-owned personal computer acts as the control panel of the measuring instrument.

By centrally managing measurement devices, it is possible to provide high-quality information required by users based on the accumulated measurement device information, and the measurement business is activated. Business models that provide only measurement device information, business that processes information based on measurement device information and distributes high-quality information, business that provides measurement databases from measurement devices, and development of measurement devices A business to sell, a business to install measurement devices, etc. were created,
Industrial applicability is extremely large.
