The observation information of each place is acquired by the sensors 20 of the terminals 1a, 1b, 1c,... Distributed, and the acquired observation information is transmitted and received between the terminals via the network 3 in a peer-to-peer manner. As described above, the observation information of each terminal 1a, 1b, 1c,... Is independently observed by the terminals 1a, 1b, 1c,. can get.

  As shown in FIG. 3, the terminals 1 a, 1 b, 1 c,... Have a communication unit 11, a control unit 12, a sensor profile database 13, a sensor usage status database 14, and an observation target information database 15. Yes.

  The communication unit 11 is for transmitting and receiving data via the network 3, and can communicate with each other in a peer-to-peer manner. The control unit 12 performs overall control. An observation program 16 is installed in the control unit 12.

  A sensor 20 is connected to the controller 12 via an interface 19. The sensor 20 is one or a plurality of sensors for acquiring observation information. The sensor 20 is, for example, a weather observation sensor, and examples thereof include a temperature sensor, a humidity sensor, and a seismic intensity sensor.

  The observation program 16 includes a sensing signal processing application program 17 and an observation data editing application program 18. The sensing signal processing application program 17 is an application program for acquiring sensing information from the sensor 20. The observation data editing application program 18 edits and processes the sensing signal from the sensor 20 to provide observation information for earthquake prediction, discomfort measurement, temperature distribution measurement, humidity distribution measurement, volcano prediction, vibration investigation, and the like. To get.

  The sensor profile database 13 indicates what type of sensor 20 is connected to the terminal, and is created according to the sensor type of the sensor 20 connected to each terminal 1a, 1b, 1c,. The In the sensor profile database 13, as shown in FIG. 4, the sensor ID, the sensor type, and the accuracy are described. Here, an accuracy item is provided in the sensor profile database 13, but this is an example, and the accuracy item is not essential. Further, other items such as the sensor manufacturer and the date and time when the sensor was attached may be provided in the sensor profile database 13.

  The sensor usage status database 14 indicates the current usage status of each sensor connected to the terminal, and is rewritten sequentially each time each sensor is used. As shown in FIG. 5, the sensor usage status database 14 describes sensor IDs, usage statuses, terminal IDs of requesting terminals, observation target IDs, and priorities.

  The observation target information database 15 indicates the relationship between the sensor type necessary for realizing the requested observation target and the observation program type, and is created in advance. As shown in FIG. 6, the observation target information database 15 describes the correspondence between the observation target ID, the sensor type, and the observation program type (observation data editing application program and sensing signal processing application program).

  In FIG. 1, the center server 2 includes a terminal profile management server 4 and an observation application management server 5.

  The terminal profile management server 4 is a server that provides profile information of each terminal 1a, 1b, 1c,... On the network 3, and has a terminal profile database 41. In the terminal profile database 41, as shown in FIG. 7, the terminal ID, the location of the terminal, the operation status, and the address (IP address) of the terminal on the network are described. For example, each terminal 1a, 1b, 1c,... Is registered in the terminal profile database 41 when connected to the network 3.

  The observation application management server 5 provides observation programs (observation data editing application program and sensing signal processing application program) necessary for observation. The observation application management server 5 is provided with an observation application database 42 in which a large number of observation data editing application programs and sensing signal processing application programs corresponding to each observation target and each sensor are accumulated.

  The operation of the observation system according to the first embodiment of the present invention configured as described above will be described with reference to the functional block diagram of FIG.

  8, each terminal 1a, 1b, 1c,... Registers the profile of the terminal in advance by the terminal profile registration unit 51. The profile of each terminal is stored in the terminal profile database 41 by the terminal profile creation unit 52 of the terminal profile management server 4. Thereby, the terminal profile database 41 as shown in FIG. 7 is generated in the terminal profile management server 4.

  The observation target determining unit 53 of the observation request source terminal (here, the observation request source terminal is the terminal 1a) inquires of the terminal profile search unit 54 of the terminal profile management server 4 about the observation request destination terminal. The inquiry of the observation request destination terminal uses, for example, the terminal arrangement destination as a key. The terminal profile search unit 54 of the terminal profile management server 4 refers to the terminal profile database 41 and searches for a request destination terminal for information corresponding to the request. Then, the search result of the corresponding request destination terminal is transmitted to the observation target determination unit 53.

  The observation target determination unit 53 of the terminal 1a determines a request destination terminal that requests observation information based on a search result from the terminal profile management server 4. Here, it is assumed that the terminal 1b is determined as the observation request destination terminal. When the observation request destination terminal is determined, the observation processing request transmission unit 55 of the terminal 1a transmits observation processing request data to the request destination terminal 1b. As shown in FIG. 9, the observation process request data includes an observation request destination terminal ID, an observation request source terminal ID, an observation target ID, and a priority.

  When the observation processing request receiving unit 56 receives the observation processing request data, the observation processing request receiving unit 56 sends the observation processing request data to the observation method determining unit 57. The observation method determination unit 57 refers to the observation target information database 15 and determines the sensor type and observation program required for the observation processing request.

  That is, as shown in FIG. 6, the observation target information database 15 describes the correspondence relationship between the observation target ID, the sensor type, and the observation program type (observation editing application program and sensing signal processing application program). ing. Further, the observation processing request data includes an observation target ID as shown in FIG. Accordingly, the sensor type corresponding to the observation processing request and the observation program can be determined with reference to the observation target information database 15. For example, if the requested observation target is earthquake prediction, referring to the observation target information database 15 shown in FIG. 6, the necessary sensor type is a seismic intensity sensor, and the necessary observation program is an earthquake survey application program, It can be seen that this is a seismic intensity sensing application program.

  When the sensor type required for the observation processing request and the observation program are determined, the observation method determination unit 57 refers to the sensor profile database 13 shown in FIG. 4 and determines the type of sensor connected to the terminal. Search for. Then, the observation processing availability determination unit 58 refers to the search result from the observation method determination unit 57 and the sensor usage database 14 to determine whether observation is possible.

  In the sensor profile database 13, sensor profile data is registered by the sensor profile registration unit 59, for example, every time a new sensor is connected. The sensor usage status database 14 registers sensor usage status information each time the sensor usage status is switched by the sensor usage status registration unit 60.

  If a sensor to be used in the requested observation target is not searched, the observation process availability determination unit 58 determines that observation is not possible, and sends observation process availability data that is not observable to the observation process availability transmission unit 64. That is, if the observation target is earthquake prediction, it is searched whether or not a seismic intensity sensor for measuring seismic intensity is connected as the sensor 20. If the seismic intensity sensor is not searched, observation is impossible.

  If the sensor to be used for the requested observation is not in use, it is determined whether there is an observation program to be used for the requested observation. If there is no observation program, the observation application download unit 61 To download the observation program to be used in the requested observation. Based on this, the observation application download unit 61 sends an observation program download request to the observation application management unit 62 of the observation application management server 5. The observation application management unit 62 sends the requested observation program to the observation application download unit 61 and downloads the observation program. When the observation application download unit 61 downloads the observation application, the observation application download unit 61 stores the downloaded observation application in the application database 63.

  If the sensor to be used for the requested observation is in use, the sensor usage status database 14 is referenced to compare the observation target being used with the observation target sent in the observation processing request data. If the observation target being used matches the observation target sent in the observation processing request data, the output of the sensor is continued.

  That is, the terminal that requests the terminal 1b for observation is not limited to the terminal 1a. It is assumed that the other terminal requests observation from the terminal 1b, or the terminal 1b performs observation at its own terminal, and the requested sensor is in use. However, even if the sensor is in use, the observation result can be used as it is if the observation object matches.

  For example, if the observation target in use is earthquake prediction, and the observation target requested by the terminal 1a is also earthquake prediction, the sensor used is the same as the seismic intensity sensor, and the observation data editing application program is also used for earthquake surveys. The application program is the same, and the sensing signal processing application program is the same in the seismic intensity sensing application program. In this case, the observation result from the sensor currently in use can be continued as it is and sent to the terminal 1a that has newly requested the observation.

  If the observation target of the sensor in use does not match the requested observation target, compare the priority in use with the requested priority and decide whether or not to observe. Yes.

  That is, for example, earthquake prediction, volcanic prediction, and vibration survey are all observed using sensing information from seismic intensity sensors (see FIG. 6). In this way, the priority is set on the assumption that the same sensor is used for different observation targets. The priority is set corresponding to the observation target. For example, earthquake predictions and volcanic predictions are set higher in priority because damage is more serious than vibration investigations such as construction. The priority of the sensor currently in use is described in the sensor usage database 14 shown in FIG. Further, the priority is added to the observation processing request data as shown in FIG. The priority of the current sensor described in the sensor usage database 14 is compared with the priority added to the observation process request data, and accordingly, whether or not observation is possible is determined. That is, observation is possible when the requested priority is higher than the priority in use, and observation is not possible when the requested priority is lower than the priority in use.

  In FIG. 8, the observation process availability determination unit 58 determines the observation availability as described above, and sends the observation availability information to the observation process availability transmission unit 64. The observation process propriety transmission unit 64 transmits observation process propriety data to the terminal 1a. As shown in FIG. 10, the observation processing availability data includes an observation request destination terminal ID, an observation request source terminal ID, an observation availability result, and the reason. The observation process availability data transmitted from the observation process availability transmission unit 64 of the terminal 1b is received by the observation process availability reception unit 65 of the terminal 1a.

  In addition, the sensing signal processing unit 66 acquires a sensing signal of the sensor 20. This sensing signal is transmitted from the sensing information transmitting unit 67, received by the sensing information receiving unit 68, and sent to the observation data editing unit 69. The observation data editing unit 69 edits and processes the sensing data to generate observation data. This observation data is sent to the observation data transmission unit 70, and the observation data transmission unit 70 transmits this observation data to the terminal 1a. The observation data receiving unit 71 of the terminal 1a receives this observation process availability data.

  Next, processing according to the first embodiment of the present invention will be described with reference to FIGS. 11 and 12.

  FIG. 11 is a sequence diagram illustrating a process according to the first embodiment of this invention. As shown in FIG. 11, the terminals 1a, 1b, 1c,... Send profile data of each terminal to the terminal profile management server 4 when connected to a network, for example (steps S1a, S1b,...). The terminal profile management server 4 registers the profile data sent from each terminal in the terminal profile database 41 (steps S2a, S2b,...).

  For example, if the terminal 1a is an observation request source terminal, the observation request source terminal 1a inquires of the terminal profile management server 4 about the profile of the terminal (step S3). Upon receiving this inquiry, the terminal profile management server 4 searches the terminal profile database 41 and transmits the search result to the terminal 1a (step S5).

  The terminal 1a receives the search result from the terminal profile management server 4 and determines a request destination terminal (step S6). Here, assuming that the terminal 1b is determined as the observation request destination terminal, the terminal 1a transmits observation processing request data to the terminal 1b (step S7).

  Upon receiving the observation process request data, the terminal 1b refers to the observation target information database 15 and determines a sensor and an observation program (step S8). Then, with reference to the sensor profile database 13 and the sensor usage status database 14, it is determined whether or not observation is possible (step S9).

  Here, if it is determined that the observation is impossible, the observation processing propriety data indicating that the observation is impossible is transmitted to the terminal 1a (step S10).

  If observation is possible, it is determined whether there is an observation program (step S11). If there is no observation program, a download request is made to the observation application management server 5 (step S12), and the observation program is downloaded. (Step S13). Then, observation process availability data indicating that observation is possible is transmitted to the terminal 1a (step S14), and observation data is transmitted (step S15).

  FIG. 12 is a flowchart showing the details of the observability determination process in steps S8 to S15 described above.

  In FIG. 12, it is determined whether observation process request data has been received (step S21). When the observation processing request data is received, based on the observation target ID, the observation target information database 15 is referred to (step S22), and the required sensor type and the required observation program are determined (step S23). ). Then, referring to the sensor profile database 13 (step S24), it is determined whether there is a sensor of the required sensor type (step S25). If there is no sensor of the required sensor type, it is determined that observation is not possible, and observation processing availability data indicating that observation processing is not possible is transmitted (step S26).

  If it is determined in step S25 that there is a sensor of the required sensor type, the sensor usage status is acquired with reference to the sensor usage status database 14 (step S27). Then, it is determined whether the sensor is in use (step S28).

  If the sensor is not in use at step S28, it is determined whether there is a required observation program (step S29). If there is a required observation program, it is determined that observation is possible, and observation processing availability data indicating that observation processing is possible is transmitted (step S30). Then, observation data obtained from the sensing information of the sensor is transmitted (step S31). Then, the sensor usage status database 14 is updated according to the new sensor usage information (step S32).

 If it is determined in step S29 that there is no requested observation program, a request for downloading the requested observation program is transmitted to the observation application management server 5 (step S33), and the observation program is downloaded. (Step S34). Then, it is determined that observation is possible, and observation processing availability data indicating that observation processing is possible is transmitted (step S30). Then, observation data obtained from the sensing information of the sensor is transmitted (step S31). Then, the sensor usage status database 14 is updated according to the new sensor usage information (step S32).
