There is also a possibility that the radioactivity diffusion situation around the road can be investigated by the probe information utilization system. A further topic of interest is the measurement of the cumulative amount of exposure by vehicle users. Even if radiation exposure on the human body is not a problem for a short period of time, there is a risk that it will be affected by prolonged exposure. Therefore, it is desirable not only to measure the radiation dose around the road, but also to store the history of exposure and cumulative exposure in association with the vehicle user.

  Non-Patent Document 2 discloses a technique for displaying a “passed road” at the time of an earthquake disaster using a probe information utilization system.

  Patent Document 1 discloses a technique for recording a radiation dose associated with accurate position information by a terminal that is mounted on a vehicle and includes a radiation detector and a GPS information receiving unit (GPS: Global Positioning System). Yes.

  Patent Document 2 discloses a slave unit that can detect radiation and transmit measurement data to the master unit, and has a separate identification number and name, and a master unit that collects radiation dose data from a plurality of slave units. It is disclosed that an individual's exposure is measured by the radiation measurement system.

  In Patent Document 3, a route candidate is extracted, an ultraviolet ray amount for each predetermined section is acquired, and an ultraviolet ray exposure amount in all intervals for each route candidate is calculated based on the obtained ultraviolet ray exposure amount for each interval. A method of displaying the total ultraviolet exposure amount in association with each route candidate is disclosed.

(First embodiment)
Next, a first embodiment of the radioactivity information utilization system 1000 of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a configuration of an embodiment of the present invention. The radioactivity information utilization system 1000 of this embodiment includes an in-vehicle information terminal 100 and a server 110. The in-vehicle information terminal 100 includes an in-vehicle control unit 101, an in-vehicle communication unit 102, an operator specifying unit 104, a radioactivity acquisition unit 105, and an operator exposure amount storage unit 106. The in-vehicle information terminal 100 may include an in-vehicle navigation unit 103 and a warning unit 120. The worker exposure amount storage unit 106 is also referred to as a worker cumulative exposure amount storage unit.

  The in-vehicle information terminal 100 is a terminal mounted on, for example, a business vehicle of a transportation company.

  The in-vehicle control unit 101 controls the in-vehicle navigation unit 103. In addition, the in-vehicle control unit 101 issues a radioactivity data acquisition instruction to the radioactivity acquisition unit 105. The radioactivity acquisition unit 105 acquires radioactivity data from the radioactivity measurement unit 107. The radioactivity measurement unit 107 is, for example, a Geiger counter attached to a car. Further, the in-vehicle control unit 101 outputs the worker ID output from the worker specifying unit 104 and the measurement result sent from the radioactivity acquisition unit 105 to the worker exposure amount storage unit 106. Further, the in-vehicle control unit 101 exchanges information with the server 110 via the in-vehicle communication unit 102.

  The in-vehicle communication unit 102 communicates with the server 110.

  The in-vehicle navigation unit 103 performs navigation such as a map display of the current location and a route display to the target location for the worker.

  As an example, the worker specifying unit 104 receives a worker's ID (Identification, hereinafter referred to as a worker ID)) by using a dedicated GUI (Graphical User Interface). The worker specifying unit 104 outputs the input ID to the in-vehicle control unit 101.

  The worker exposure amount storage unit 106 updates the cumulative radiation exposure amount (hereinafter referred to as worker cumulative exposure amount) for each worker based on the worker ID and the radioactivity measurement value output from the in-vehicle control unit 101. To do. FIG. 4 is an example of the contents stored in the worker exposure amount storage unit 106. The worker exposure amount storage unit 106 stores a worker accumulated exposure amount (unit: millisievert) in association with the worker ID.

  The server 110 includes a server control unit 111, a database 112, and a server communication unit 113. Server 110 communicates with a plurality of in-vehicle information terminals 100. The server control unit 111 of the server 110 adds the worker accumulated exposure amount corresponding to the worker ID transmitted from the in-vehicle communication unit 102 of the in-vehicle information terminal 100 to the server communication unit 113 to the database 112. Specifically, the server control unit 111 adds the transmitted worker cumulative exposure amount to the cumulative exposure amount corresponding to the worker ID stored in the database 112 at this time and registers it.

  The server communication unit 113 communicates with the in-vehicle information terminal 100. The server control unit 111 outputs the stored contents in the database 112 to the server communication unit 113 in accordance with the request sent to the server communication unit 113. The server communication unit 113 transmits the registration content of the database 112 to the in-vehicle communication unit 102 of the in-vehicle information terminal 100.

  Next, the operation of the radioactivity information utilization system 1000 according to the first embodiment of the present invention will be described. FIG. 5 is a flowchart for explaining specific processing in the radioactivity information utilization system 1000 according to the first embodiment of the present invention.

  The worker inputs, for example, an ID assigned in advance for each worker by the numeric keypad input or the like to the worker specifying unit 104 at the start of the work (S11).

  The worker specifying unit 104 outputs the input ID to the in-vehicle control unit 101.

  The vehicle-mounted control unit 101 issues a radioactivity data acquisition instruction to the radioactivity acquisition unit 105 (S12). Further, the in-vehicle control unit 101 issues a navigation start instruction to the in-vehicle navigation unit 103 (S13). The operator drives the vehicle and starts operation (S14). The measurement value of the radiation dose is accumulated and stored in the worker exposure dose storage unit 106 at predetermined time intervals (S15). The vehicle-mounted control unit 101 determines whether or not the operation has ended (S16).

  The end of the operation is determined by the driver's operation. For example, when the measurement end button is pressed, when the ignition key is removed, and when the parking brake is depressed, it is determined that the operation is finished. In addition to these, when the position data of the in-vehicle navigation unit 103 does not fluctuate for a certain period of time, the operation end may be determined.

  If the operation has not ended (S16 NO), S15 and S16 are repeated. If the operation has ended (S16 YES), the radioactivity acquisition unit 105 ends the acquisition of radioactivity data.

  The in-vehicle control unit 101 transmits the accumulated worker exposure amount stored in the worker exposure amount storage unit 106 to the server communication unit 113 of the server 110 in association with the worker ID via the communication unit 102 (S17). ).

  The server control unit 111 of the server 110 adds the ID sent to the server communication unit 113 and the worker's cumulative exposure amount related to this ID to the cumulative exposure amount stored in the database 112 so far. Save (S18).

  When the cumulative amount of exposure at the time of addition does not exceed a predetermined value by a company or organization operating this system (S19 YES), the server control unit 111 determines whether the in-vehicle information terminal 100 and the server 110 End communication. If exceeded (NO in S19), for example, the server control unit 111 transmits a warning to the in-vehicle information terminal 100 via the server communication unit 113. When the in-vehicle control unit 101 of the in-vehicle information terminal 100 receives this warning, the in-vehicle control unit 101 transfers the warning to the warning unit 120, and the warning unit 120 next takes the warning to the user, for example, by a predetermined sound or image. Guidance instructing the appropriate action is output (S20). As another example, a warning process for displaying a warning may be performed. Another example of the warning process is to transmit the worker ID and the cumulative exposure amount to a business management system or the like operated by a company or organization that operates the system.

  In addition to the warning process, the vehicle-mounted information terminal 100 takes various measures. For example, the in-vehicle control unit 101 automatically performs an operation of closing the window so that outside air is not taken in by the vehicle. In addition to these, it is possible to display guidance to that effect. Note that the warning unit 120 is not necessarily provided when the in-vehicle communication unit 102 has a warning function or when no warning is required.

FIG. 4 shows an example of the cumulative exposure amount stored in the database 112 in the server 110.

  For example, assume that the annual exposure limit is set to 1 mSv at companies and organizations that operate this system. When the worker with worker ID 1124 in FIG. 4 uses the above system, the cumulative exposure stored in the database 112 of the server 110 at the start of operation (S14) was 0.7 millisievert. It is assumed that the cumulative worker exposure amount transmitted to the server communication unit 113 after the operation is finished (S16) is 0.4 millisievert. In this case, the server control unit 111 of the server 110 adds 1.1 millisie to the database 112 by adding the current worker cumulative exposure amount 0.4 millisievert to the cumulative exposure amount 0.7 millisievert so far. The belt is stored as a cumulative exposure amount (S18). Since this value exceeds 1 millisievert, the annual exposure limit (NO in S19), the warning unit 120 performs a predetermined warning process (S20).

  In this embodiment, the cumulative exposure amount corresponding to the worker ID is temporarily accumulated in the worker exposure amount storage unit 106 of the in-vehicle information terminal 100 during one operation, and the database 112 of the server 110 after the operation ends. Has been added. That is, the database 112 stores the cumulative exposure amount for all operations. When the server 110 is not used, the cumulative exposure amount corresponding to the worker ID is added to the worker exposure amount storage unit 106 for all operations.

  In this embodiment, the example which performs a warning process at the time of the operation completion was described. When the stored content of the worker exposure amount storage unit 106 exceeds the preset reference value, the warning unit 120 may perform warning processing at that time.

  In-vehicle control unit 101, in-vehicle communication unit 102, in-vehicle navigation unit 103, worker identification unit 104, radioactivity acquisition unit 105, warning unit 120, server control unit 111, and server communication unit 113 are hardware that is a combination of logic elements. It may be configured by software executed by a computer. The worker exposure amount storage unit 106 and the database 112 are storage media such as a magnetic disk and a semiconductor memory.

  In the present embodiment, the in-vehicle control unit 101 and the in-vehicle communication unit 102 are provided independently. However, the worker exposure amount storage unit 106, the radioactivity acquisition unit 105, and the worker specification unit 104 can share the functions of the in-vehicle control unit 101 and the in-vehicle communication unit 102.

  In the present embodiment, the worker ID is used to identify the worker. However, not only the worker ID but any method that can identify the worker can be used instead of the worker ID. For example, fingerprint authentication, voice recognition, and pupil authentication can be used.

According to the present embodiment, the user can record his / her cumulative radiation dose by simply inputting an ID without wearing a sensor on his / her body. Therefore, the user can efficiently record the cumulative radiation dose with a small burden. .
(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIGS. The corresponding parts in FIGS. 2 and 3 are assumed to have the same functions as those of the first embodiment unless otherwise described. FIG. 2 shows a configuration of a radioactivity information utilization system 1000 that measures radioactivity on the road 400. The difference from the first embodiment is that the worker specifying unit 104 is not provided, and the road exposure amount storage unit 209 is provided instead of the worker exposure amount storage unit 106.

  The server 210 includes a server control unit 211, a database 212, and a server communication unit 213.

  In the first embodiment, the accumulated exposure amount is stored in the database 112 for each worker. In the second embodiment, the section cumulative exposure amount related to the road section 40 obtained by the in-vehicle navigation unit 203 is accumulated in the road exposure amount storage unit 209, and the section cumulative exposure amount is stored in the server 210 at the end of operation. It is transmitted and stored in the database 212 as the road section cumulative exposure amount. By operating the system of FIG. 2, data relating to each road and the amount of exposure that is expected to be accumulated on the workers by running the road is stored in the database 212.

  A specific measurement method will be described below. As shown in FIG. 6, the road 400 is divided into road sections 40 of a certain length, and the divided road sections 40-1, 40-2, 40-3, 40-3, 40-n are The vehicle navigation unit 203 is registered in association with the longitude and latitude range. The in-vehicle navigation unit 203 grasps the longitude and latitude of the position of the vehicle by GPS and specifies the section to which it belongs at that time.

  The in-vehicle control unit 201 associates the radioactivity measurement value acquired by the radioactivity acquisition unit 205 with the section recognized by the in-vehicle navigation unit 203 (hereinafter referred to as a section cumulative exposure amount). Is recorded in the road exposure amount storage unit 209. Further, the in-vehicle control unit 201 outputs the accumulated section exposure amount stored in the road exposure amount storage unit 209 to the in-vehicle communication unit 202. The in-vehicle communication unit 202 transmits this to the server communication unit 213 of the server 210, and the server control unit 211 associates this section cumulative exposure amount with the section and stores it in the database 212 as a road section cumulative exposure amount.

  FIG. 7 shows a flowchart for measuring the cumulative exposure amount due to running in each section. The worker inputs a measurement start instruction to the in-vehicle control unit 201 of the in-vehicle information terminal 100 at the start of operation, and the in-vehicle control unit 201 instructs the radioactivity acquisition unit 205 to start measurement (S110). The radioactivity acquisition unit 205 starts acquiring radioactivity data from the radioactivity measurement unit 207 (S120).

  The radioactivity measurement value represented by the radiation dose is stored as a section cumulative exposure dose in the road exposure dose storage unit 209 at regular time intervals.

  The vehicle-mounted control unit 201 issues a navigation start instruction to the vehicle-mounted navigation unit 203, and the vehicle-mounted navigation unit 203 starts a navigation operation (S130). The in-vehicle navigation unit 203 identifies the section 40 on the road 400 to which the current position of the vehicle belongs. The worker starts operation and starts operation (S140).

  The in-vehicle navigation unit 203 determines whether or not the vehicle position has entered the next section (S150). When it is not in the next section (S150 NO), the in-vehicle control unit 201 outputs the measurement result in S120 to the road exposure amount storage unit 209. The road exposure storage unit 209 accumulates the radiation dose measured in association with this section in the temporary storage area (S170).

  When it is in the next section (S150 YES), the in-vehicle control unit 201 reads the cumulative radiation dose of the previous section stored in the temporary storage area (S160). The vehicle-mounted control unit 201 updates the radiation dose of the previous section as the section cumulative exposure amount and registers it in the road exposure amount storage unit 209 (S180). The in-vehicle control unit 201 determines whether or not the operation has ended. The end of the operation is determined by the driver's operation such as pressing the operation end button or the position data of the in-vehicle navigation unit 103 (S190). If the service has not ended (NO in S190), S150 and S170 are repeated. When the operation is finished (YES in S190), the in-vehicle control unit 201 transmits the section cumulative exposure amount in the road exposure amount storage unit 209 to the server 210 via the in-vehicle communication unit 202 (S200).

  The server control unit 211 of the server 210 initially registers the section cumulative exposure amount sent to the server communication unit 213 in the database 212 for the first time. After the first time, the server control unit 211 overwrites and saves the accumulated cumulative amount of road sections that has been stored up to this point (S210). When the road section cumulative radiation dose is recorded for all sections constituting the specific road, it is possible to obtain the cumulative radiation dose associated with the specific road by taking the sum of these. The in-vehicle information terminal 200 may include a warning unit 220. The warning unit 220 issues a warning when the road section cumulative exposure amount exceeds a preset threshold value.

  FIG. 3 shows a configuration of the radioactivity information utilization system 1000 that uses data of the road section cumulative exposure amount acquired by the radioactivity information utilization system 1000 of FIG. The radioactivity acquisition unit 305 acquires data on the cumulative amount of road section exposure from the database 312 of the server 310 via the in-vehicle communication unit 302. The server 310 includes a server control unit 311, a database 312, and a server communication unit 313. The function of the server 310 is the same as the function of the server 210.

  FIG. 8 is a flowchart showing the operation of the radioactivity information utilization system 1000. The worker inputs the worker ID assigned in advance for each worker from the worker specifying unit 304 by using the numeric keypad or the like, for example, at the vehicle-mounted information terminal 300 at the start of business (S310). The worker specifying unit 304 outputs the input ID to the in-vehicle control unit 301. The vehicle-mounted control unit 301 issues a navigation start instruction to the vehicle-mounted navigation unit 303 (S320).

  The operator drives the vehicle and starts operation (S330). The in-vehicle control unit 301 outputs the number of the section 40 obtained from the in-vehicle navigation unit 303 to the in-vehicle communication unit 302 to the radioactivity acquisition unit 305. The radioactivity acquisition unit 305 transmits the number of the section 40 to the server control unit 311 via the in-vehicle communication unit 302 and the server communication unit 313 of the server 310.

  The server control unit 311 acquires the road section cumulative exposure amount data corresponding to the number of the section 40 from the database 312 and transmits the data to the radioactivity acquisition unit 305 via the server communication unit 313 and the in-vehicle communication unit 302 (S340). . The vehicle-mounted control unit 301 records the road section cumulative exposure amount acquired from the radioactivity acquisition unit 305 as the worker cumulative exposure amount in the worker exposure amount storage unit 306 in association with the worker ID (S350).

  The in-vehicle navigation unit 303 determines whether the position of the vehicle has entered the next section (S360). When it is not in the next section (S360 NO), the in-vehicle control unit 301 determines whether or not the operation has ended (S370). The end of the operation is determined by a driver's operation or position data of the in-vehicle navigation unit 103.

  When it is in the next section (S360 YES), S340 and S350 are repeated. When the vehicle-mounted control unit 301 determines in S370 that the vehicle is in operation, the processing from S360 is repeated. If the in-vehicle control unit 301 determines in S370 that the operation has ended, the in-vehicle control unit 301 recognizes the worker ID recorded in the worker exposure amount storage unit 306 and the worker accumulated exposure amount associated with the worker ID. Is transmitted to the server communication unit 313 via the in-vehicle communication unit 302 (S380).

  The server control unit 311 of the server 310 sets the ID sent to the server communication unit 313 and the worker accumulated exposure amount associated with this ID to the ID corresponding to this ID stored in the database 312 so far. It adds and preserve | saves to the accumulation exposure amount linked | related (S390).

  Similar to the first embodiment, the server 310 is not necessarily required. The worker accumulated exposure amount can also be stored in the worker exposure amount storage unit 106.

  In the above process, alarm processing by the warning unit 320 may be added as in the first embodiment. In this embodiment, when the next section is entered, the road section cumulative radiation dose of that section is acquired. On the other hand, the embodiment in which the road section cumulative radiation dose of the previous section is acquired at the time of entering the next section without acquiring the road section cumulative radiation dose of the section at the time of entering the section. May be taken.

  In addition, when it is determined that the operation has been completed without completing the acquired section, calculate the ratio of the distance traveled in the section to the distance of the entire section, and multiply the cumulative radiation dose in that section by the ratio The cumulative radiation dose may be acquired by

  In the present embodiment, as shown in FIG. 11, a route search unit 208 can be used together. In this case, the route to be operated is selected from the routes searched by the route search unit 208. The in-vehicle navigation unit 303 navigates the vehicle so as to operate the selected route. The route search unit 208 can acquire road section cumulative exposure dose data from the database 212 for a plurality of extracted routes, and can display them in the order of decreasing cumulative radiation dose.

  According to the present embodiment, for example, when an operator sets a route for operation (road route), the cumulative exposure amount after operation can be calculated without performing actual operation. Therefore, for example, when there are a plurality of route candidates, the cumulative exposure amount at the time of using each route can be calculated, so it is possible to present a route with a small cumulative exposure amount on the in-vehicle navigation unit 303. Alternatively, a plurality of routes may be presented in ascending order of cumulative exposure.

  In the system of the first embodiment, the warning is performed after the operation, but in the second embodiment, when the route is set, for example, when the annual exposure limit is exceeded, a predetermined warning process is performed. Can be done.

  Also, if it becomes clear that the annual exposure limit will be exceeded just by using a specific road, the in-vehicle navigation unit 303 registers the road as an unusable road to reduce search work, selection work, etc. It is also possible.

  In the above-described embodiment, the road section cumulative exposure amount data is acquired from the database 312. In contrast, the in-vehicle information terminal 300 includes a road exposure amount storage unit 309, and the radioactivity acquisition unit 305 acquires the data of the road section cumulative exposure amount from the road exposure amount storage unit 309. FIG. May be. In this case, the road exposure amount storage unit 309 stores road section cumulative exposure amount data in advance.

  Note that the database may be created individually for each vehicle. As described above, the above-described embodiment is a case where a vehicle that measures radioactivity and a vehicle that utilizes acquired radioactivity data are separate, but these are combined into one, It can be mounted on a vehicle.

The road exposure amount storage unit 509 is equal to the road exposure amount storage unit 209 of the in-vehicle information terminal 200, and the worker exposure amount storage unit 506 is equal to the worker exposure amount storage unit 106 of the in-vehicle information terminal 100. The radioactivity acquisition unit 505 has the functions of the radioactivity acquisition unit 205 in FIG. 2 and the radioactivity acquisition unit 305 in FIG. 3.

  The server 510 includes a server control unit 511, a database 512, and a server communication unit 513.
