The data packet is composed of measurement data and an ID (for example, a unique ID) as a data identifier. As described above, the measurement data is data representing the result of radiation measurement (dose rate, etc.), temperature data, measurement time data, position data, and the like. The ID is a common ID for the radiation measuring apparatus 10 and the host apparatus 12.

Hereinafter, the measurement data correspondence table (correspondence table) will be described in detail with reference to FIG. In the measurement data correspondence table, information indicating the type of measurement data and an ID (for example, a unique ID) as a data identifier representing the measurement data are associated with each other. For example, the ID of “dose rate A” as the measurement data is “000”, the ID of “dose rate B” as the measurement data is “001”, and the ID of “temperature” as the measurement data is “002”. The ID of “measurement time” as the measurement data is “003”. The data table corresponding to the measurement data is stored in, for example, the radiation measurement device 10 and the host device 12.

In this measurement data correspondence table, even if the types of measurement data are the same, different data identifiers (for example, unique IDs) are associated with each other according to the state (status, state) of the measurement data. ing. For example, when the dose rate A as the measurement data is data representing the dose rate itself, the ID “A01” is given to the dose rate A. When the dose rate A is data representing a spectrum, the ID “B01” is given to the dose rate A. When the dose rate A is time-corrected data, the ID “C01” is assigned to the dose rate A. Thus, even if the dose rate A is the same, different IDs are assigned according to the state. This measurement data correspondence table is stored in, for example, the radiation measurement device 10 and the host device 12.

In the present embodiment, in the detectors 16 and 18 and the measuring unit 20, an ID may be given to each measurement data according to the measurement data correspondence table shown in FIG. 4, or the measurement data shown in FIG. An ID may be assigned to each measurement data according to the correspondence table.

Hereinafter, the data file configuration definition file will be described in detail with reference to FIG. FIG. 6 shows an example of the data file configuration definition file. For example, a data file configuration definition file is created in advance for each data file. In the example shown in FIG. 6, a data file configuration definition file for generating a data file having the format of data file A, a data file configuration definition file for generating a data file having the format of data file B, and data A data file configuration definition file for generating a data file having the format of file C is created in advance. The data file generation unit 36 generates a data file having a data format defined by the data file configuration definition file according to one data file configuration definition file among the plurality of data file configuration definition files. For example, a data file configuration definition file may be created in advance for each type of measurement data, or a data file configuration definition file may be created in advance for each combination of multiple types of measurement data. Of course, one data file configuration definition file may be created in advance, and the data file generation unit 36 may generate the data file according to the data file configuration definition file.

In the data file configuration definition file, IDs as a plurality of data identifiers are listed. Here, the data file configuration definition file for generating a data file having the format of the data file A will be described in detail. The data file configuration definition file is, for example, a definition file for generating a text data file. Specifically, in the first line of the data file configuration definition file, the character string "data1" is described after the space (blank) for one character, and the character ":" is added after the character string "data1". (Colon)" is described. In the second line, “ID:000” as a data identifier is described after the space for two characters. The data file generation unit 36 is scheduled to input the measurement data having the ID “000” to the area where the data identifier “ID:000” is described. The third line has the same data structure as the first line. That is, the character string “data2” is described after the space for one character, and the symbol “: (colon)” is described after the character string “data2”. The fourth line has the same data structure as the second line. That is, “ID:001” as a data identifier is described after the space for two characters. The data file generation unit 36 is scheduled to input the measurement data having the ID “001” to the area where the data identifier “ID:001” is described. The same applies to the subsequent lines.

The data file configuration definition file is stored in, for example, the storage unit 40 of the external transmission unit 22. Of course, the data file configuration definition file may also be stored in the host device 12. The ID as the data identifier is, for example, a unique ID that can be recognized by another device such as the host device 12. In addition, the definition content of the data file configuration definition file (for example, the format of data defined by the data file configuration definition file, the type of data included in the data file configuration definition file, etc.) is changed in response to a request from the host device 12. It is possible to do. For example, even if the data format defined by the data file configuration definition file is a text format, the specifications of the data description (for example, the data arrangement order, the presence/absence of spaces (blanks), etc.) It may be different for each request of the administrator to use). For example, one user requests a data file in which each measurement data is described in the order of the measurement data A, B, and C, and another user measures the measurement data A even if the same measurement data type is used. , C, B may be requested in the order of the data file in which each measurement data is described. Also, the requested measurement data may differ for each user. For example, one user may be requesting a data file in which the measurement data A and B are described, and another user may be requesting a data file in which the measurement data A and C are described. In order to meet such a request, the definition contents of the data file configuration definition file can be changed. The control unit 42 of the external transmission unit 22 changes the definition content of the data file configuration definition file in response to the request.

Hereinafter, the communication medium (transmission method) definition file will be described in detail with reference to FIG. 7. FIG. 7 shows an example of the communication medium definition file. In the communication medium definition file, a name of the communication medium and an ID (for example, a unique ID) as a communication medium identifier for identifying the communication medium are associated with each other. In the example shown in FIG. 7, the communication medium X is associated with ID “00X”, the communication medium Y is associated with ID “00Y”, and the communication medium Z is associated with ID “00Z”. It is attached. For example, the communication medium X is a communication medium that can be used in urban areas but cannot be used in the mountains (for example, wireless LAN). The communication medium Y is a communication medium (for example, satellite communication) that can be used both in the city and in the mountains. The external communication unit 38 corresponds to, for example, the communication media X, Y, Z, and has a function of transmitting a data file to the host device 12 according to the communication media X, Y, Z. For example, the external communication unit 38 transmits the data file to the host device 12 according to one communication medium among the plurality of communication media. Of course, one communication medium is defined in the communication medium definition file, and the external communication unit 38 may transmit the data file to the host device 12 according to the communication medium.

The communication medium definition file is stored in the storage unit 40 of the external transmission unit 22, for example. Of course, the communication medium definition file may also be stored in the host device 12. The ID as the communication medium identifier is a common ID between the radiation measuring apparatus 10 and the host apparatus 12, that is, an ID shared by the radiation measuring apparatus 10 and the host apparatus 12, and can be recognized by the radiation measuring apparatus 10 and the host apparatus 12. It is a unique ID. Further, the definition content of the communication medium definition file (that is, the communication medium used) can be changed in response to a request from the host device 12. For example, when the radiation measuring apparatus 10 is installed in an environment (for example, an urban area) where a wireless LAN can be used, a user may request a communication medium (for example, the communication medium X, Y) corresponding to the wireless LAN. is assumed. Further, when the radiation measuring apparatus 10 is installed in an environment where a wireless LAN cannot be used (for example, in the mountains), it is assumed that a user requests a communication medium (for example, communication medium Y) compatible with satellite communication. .. In order to meet such a request, the definition content of the communication medium definition file can be changed. For example, when only the communication medium X is defined in the communication medium definition file, if the communication medium X cannot transmit/receive the data file and the communication medium Y can transmit/receive the data file, It is envisioned that a change (eg, change from communication medium X to communication medium Y) is requested by the user. In this case, the control unit 42 of the external transmission unit 22 changes the communication medium defined by the communication medium definition file from the communication medium X to the communication medium Y in response to the request, and the external communication unit 38 sets the communication medium Y to the communication medium Y. According to the above, the data file is transmitted to the host device 12.

Hereinafter, the communication protocol definition file will be described in detail with reference to FIG. FIG. 8 shows an example of the communication protocol definition file. In the communication protocol definition file, a name of the communication protocol and an ID (for example, a unique ID) as a communication protocol identifier for identifying the communication protocol are associated with each other. In the example shown in FIG. 8, the communication protocol a is associated with the ID “00a”, and the communication protocol b is associated with the ID “00b”. For example, the communication protocol a is a protocol that sends a data file to the host device 12 once a day, and the communication protocol b is a protocol that sends a data file to the host device 12 once a hour. Is. In addition, a communication protocol that defines the Push system, a communication protocol that defines the Pull system, and the like may be defined in the communication protocol definition file. The external communication unit 38 transmits the data file to the host device 12 according to one communication protocol among the plurality of communication protocols. Of course, one communication protocol is defined in the communication protocol definition file, and the external communication unit 38 may transmit the data file to the host device 12 according to the communication protocol.

The communication protocol definition file is stored in the storage unit 40 of the external transmission unit 22, for example. Of course, the communication protocol definition file may be stored in the host device 12. The ID as the communication protocol identifier is a common ID between the radiation measuring apparatus 10 and the host apparatus 12, that is, an ID shared by the radiation measuring apparatus 10 and the host apparatus 12, and can be recognized by the radiation measuring apparatus 10 and the host apparatus 12. It is a unique ID. Further, the definition content of the communication protocol definition file (that is, the communication protocol used) can be changed in response to a request from the host device 12. For example, it is assumed that a change in the number of times the data file is transmitted or a change in the transmission/reception method is required due to a change in the situation on the user side. In order to meet such a request, the definition contents of the communication protocol definition file can be changed. For example, when only the communication protocol a is defined in the communication protocol definition file and another communication protocol b is requested, the control unit 42 of the external transmission unit 22 responds to the request by the communication protocol definition file. The communication protocol defined by is changed from the communication protocol a to the communication protocol b, and the external communication unit 38 transmits the data file to the host device 12 according to the communication protocol b.

Hereinafter, the data file generation process by the data file generation unit 36 will be described in detail with reference to FIG. 9. FIG. 9 is a diagram for explaining the processing.

The measurement data group 44 includes a plurality of measurement data obtained by the detectors 16, 18 and the temperature sensor. In the measurement data group 44, the ID as a data identifier and the content (data entity) of the measurement data are associated with each other for each measurement data. This correspondence is performed by the detectors 16 and 18 and the measurement unit 20 according to the measurement data correspondence table shown in FIGS. 4 and 5, for example. The measurement data group 44 is transmitted from the measurement unit 20 to the external transmission unit 22 as a data packet.

In the external transmission unit 22, the data file generation unit 36 uses the measurement data (data entity) in the measurement data group 44 as a data packet as a file element according to the data file configuration definition file stored in the storage unit 40. Generate a data file that In the example shown in FIG. 9, the data file configuration definition file 46 is specified by the user, and the external transmission unit 22 generates the data file 48 according to the data file configuration definition file 46. Specifically, the data file generation unit 36 maintains the format of the data defined by the data file configuration definition file 46, and the character string of the ID as the data identifier described in the data file configuration definition file 46, It is replaced with the measurement data corresponding to the ID in the measurement data group 44. For example, since the measurement data (data entity) corresponding to the ID “000” in the measurement data group 44 is “999”, the data file generation unit 36 causes the data file configuration definition file 46 to store the character string (ID “ 000”) is replaced with a character string “999” representing the measurement data corresponding to the ID “000”. The same applies to other IDs. As a result, the character string of the ID in the data file configuration definition file 46 is converted into a character string representing the measurement data, and as a result, the data file 48 is generated. The data file 48 is transmitted to the host device 12 according to the communication medium defined by the communication medium definition file and the communication protocol defined by the communication protocol definition file.

Hereinafter, the operation of the radiation measurement system according to the present embodiment will be described with reference to FIG. 10. FIG. 10 is a sequence diagram showing the operation.

First, the external transmission unit 22 of the radiation measurement apparatus 10 transmits the default data file configuration definition file to the host apparatus 12 via the communication path 14 (S01). The default data file configuration definition file is a definition file previously stored in the storage unit 40 of the external transmission unit 22. For example, when the host device 12 requests a definition file from the radiation measuring apparatus 10, the external transmission unit 22 sends a default data file configuration definition file to the host device 12 in response to the request. The request for the definition file may be made in response to a user's instruction, or may be automatically made at a preset timing. The external transmission unit 22 transmits the data file configuration definition file to the host device 12 using a communication medium that can be used by the host device 12 (a communication medium that the host device 12 supports). The communication medium (transmission method) is a preset communication medium, for example, the communication medium used when the definition file is transmitted from the radiation measurement apparatus 10 to the host apparatus 12.

When the data file configuration definition file is sent from the radiation measuring apparatus 10 to the host device 12, the user of the host device 12 refers to the data file configuration definition file and determines whether or not the data file configuration definition file has been changed ( S02). For example, the data file configuration definition file is displayed on the display device (for example, a liquid crystal display) of the host device 12, and the user determines whether or not the data file configuration definition file is changed based on the display content. When the data file configuration definition file does not define the format (output format) of the data file requested by the user, the user requests modification of the data file configuration definition file. On the other hand, when the data file configuration definition file defines the format of the data file requested by the user, the user does not request the modification of the data file configuration definition file. For example, the user uses an input device (for example, a keyboard or an operation panel) of the host device 12 to instruct whether or not there is a request for changing the data file configuration definition file.

Of course, the host device 12 may automatically determine whether or not the data file configuration definition file is changed. For example, the host device 12 stores a data file configuration definition file that defines the content according to the user's request, and stores the data file configuration definition file and the data file configuration definition file transmitted from the radiation measurement apparatus 10. By comparing, it is determined whether the definition file has been changed. For example, when the difference between both definition files is equal to or greater than a preset threshold value, the host device 12 determines to change the data file configuration definition file. On the other hand, when the difference between both definition files is less than the threshold value, the host device 12 determines not to change the data file configuration definition file.

The host device 12 transmits information indicating the presence/absence of a request to change the data file configuration definition file to the radiation measuring apparatus 10 using a communication medium that can be used by the host device 12 (S03). When the change of the data file configuration definition file is requested, the host device 12 determines whether the changed data file configuration definition file itself or data representing the definition content of the changed data file configuration definition file (for example, as a data identifier). Data in which the IDs are listed) are transmitted to the radiation measuring apparatus 10. The changed data file configuration definition file itself or the data representing the content of the changed data file configuration definition file is, for example, data designated or created by the user of the host device 12.

When the external transmission unit 22 of the radiation measuring apparatus 10 receives the information indicating the presence/absence of the request for changing the data file configuration definition file from the host apparatus 12, the external transmission section 22 uses the communication medium available to the host apparatus 12 and indicates that the reception has been completed. The reply is transmitted to the host device 12 (S04).

When the change of the data file configuration definition file is requested, the control unit 42 of the radiation measurement apparatus 10 changes the definition content of the data file configuration definition file according to the change request from the host device 12. For example, when the changed data file configuration definition file itself is transmitted from the host device 12 to the radiation measurement apparatus 10, the control unit 42 changes the default data file configuration definition file stored in the storage unit 40 to the changed data file configuration definition file. Replace with the data file configuration definition file of. When data representing the definition content of the changed data file configuration definition file (for example, data in which IDs as data identifiers are listed) is transmitted from the host device 12 to the radiation measurement apparatus 10, the control unit 42 causes the storage unit to The definition content of the default data file configuration definition file stored in 40 is changed to the definition content of the changed data file configuration definition file. When the change of the data file configuration definition file is not requested, the definition content of the default data file configuration definition file stored in the storage unit 40 is maintained without being changed.

Next, the external transmission unit 22 of the radiation measuring apparatus 10 uses the communication medium that can be used by the host device 12 to store the default communication medium definition file or the communication medium defined in the communication medium definition file. The ID is transmitted to the host device 12 (S05). The default communication medium definition file is a definition file previously stored in the storage unit 40 of the external transmission unit 22.

When the radiation measuring apparatus 10 sends the communication medium definition file or the ID of the communication medium to the host apparatus 12, the user of the host apparatus 12 refers to the communication medium definition file or the ID of the communication medium to refer to the communication medium definition file. Whether or not there is a change is determined (S06). For example, the communication medium definition file or the ID of the communication medium is displayed on the display device of the host device 12, and the user determines whether or not the communication medium definition file has been changed based on the display content. If the communication medium definition file does not define a communication medium that can be used by the host device 12 (a communication medium that the host device 12 supports), or if the ID of the communication medium is the communication that the host device 12 can use. If the media is not represented, the user requests modification of the communication media definition file. On the other hand, if the communication medium definition file defines a communication medium that can be used by the host device 12, or if the ID of the communication medium represents a communication medium that can be used by the host device 12, the user: Does not request to change the communication medium definition file. Of course, even if the communication medium definition file defines a communication medium that can be used by the host device 12, if the communication medium definition file does not define the communication medium requested by the user, May request modification of the communication media definition file. Similarly, even if the ID of the communication medium represents a communication medium available to the host device 12, if the ID of the communication medium does not represent the communication medium requested by the user, the user The communication medium definition file may be requested to be changed. For example, the communication medium defined by the communication medium definition file may be different from the communication medium requested by the user, depending on conditions such as the communication charge and the communication speed. In such a case, it is assumed that the user requests the change of the communication medium. For example, the user uses the input device of the host device 12 to instruct whether there is a change request for the communication medium definition file.

Of course, the host device 12 may automatically determine whether or not the communication medium definition file has been changed. For example, if the communication medium definition file does not define a communication medium that can be used by the host device 12, the host device 12 determines to change the communication medium definition file. On the other hand, when the communication medium definition file defines a communication medium that can be used by the host device 12, the host device 12 determines not to change the communication medium definition file. The host device 12 may also store information indicating the communication medium designated by the user. In this case, when the communication medium defined in the communication medium definition file is different from the communication medium specified by the user, the host device 12 determines to change the communication medium definition file. On the other hand, when the communication medium defined in the communication medium definition file is the same as the communication medium specified by the user, the host device 12 determines not to change the communication medium definition file.

The host device 12 transmits the information indicating the presence/absence of the request for changing the communication medium definition file to the radiation measuring apparatus 10 by using the communication medium that can be used by the host device 12 (S07). When the change of the communication medium definition file is requested, the host device 12 measures the changed communication medium definition file itself or the data representing the changed communication medium (for example, ID as a communication medium identifier) for radiation measurement. Send to device 10. The changed communication medium definition file itself or data representing the changed communication medium is, for example, data designated or created by the user of the host device 12. For example, when the ID of the default communication medium is "00X", and the host device 12 does not support the communication medium of ID "00X" but the communication medium of ID "00Y". The host device 12 transmits the character string “00Y” as the ID of the communication medium to the radiation measuring apparatus 10.

When the external transmission unit 22 of the radiation measuring apparatus 10 receives the information indicating the presence/absence of the request for changing the communication medium definition file from the host apparatus 12, the external transmission section 22 uses the communication medium available to the host apparatus 12 and returns a response indicating that the communication apparatus has received the information. Is transmitted to the host device 12 (S08).

When the change of the communication medium definition file is requested, the control unit 42 of the radiation measurement apparatus 10 changes the definition content of the communication medium definition file according to the change request from the host device 12. For example, when the changed communication medium definition file itself is transmitted from the host device 12 to the radiation measurement apparatus 10, the control unit 42 sets the default communication medium definition file stored in the storage unit 40 to the changed communication medium. Replace with the media definition file. When the data representing the changed communication medium (for example, an ID as a communication medium identifier) is transmitted from the host device 12 to the radiation measuring apparatus 10, the control unit 42 causes the control unit 42 to store the default communication medium. Change the definition contents of the definition file to the changed communication medium. When the change of the communication medium definition file is not requested, the definition content of the default communication medium definition file stored in the storage unit 40 is maintained without being changed.

Next, the external transmission unit 22 of the radiation measurement apparatus 10 uses a communication medium that can be used by the host apparatus 12 to store the default communication protocol definition file or the communication protocol defined in the communication protocol definition file. The ID is transmitted to the host device 12 (S09). The default communication protocol definition file is a definition file previously stored in the storage unit 40 of the external transmission unit 22.

When the communication protocol definition file or the communication protocol ID is sent from the radiation measuring apparatus 10 to the host device 12, the user of the host device 12 refers to the communication protocol definition file or the communication protocol ID to refer to the communication protocol definition file. Whether or not there is a change is determined (S10). For example, the communication protocol definition file or the ID of the communication protocol is displayed on the display device of the host device 12, and the user determines whether or not the communication protocol definition file has been changed based on the display content. If the communication protocol definition file does not define a communication protocol that the host device 12 can use (a communication protocol that the host device 12 supports), or if the communication protocol ID is a communication that the host device 12 can use. If the protocol is not represented, the user requests modification of the communication protocol definition file. On the other hand, if the communication protocol definition file defines a communication protocol that the host device 12 can use, or if the communication protocol ID indicates a communication protocol that the host device 12 can use, the user: Do not request to change the communication protocol definition file. Of course, even if the communication protocol definition file defines the communication protocol that can be used by the host device 12, if the communication protocol definition file does not define the communication protocol requested by the user, May request modification of the communication protocol definition file. Similarly, even if the communication protocol ID represents a communication protocol that can be used by the host device 12, if the communication protocol ID does not represent the communication protocol requested by the user, the user Alternatively, the modification of the communication protocol definition file may be requested. For example, the communication protocol defined by the communication protocol definition file may be different from the communication protocol requested by the user, depending on conditions such as the transmission frequency of the data file. In such a case, it is assumed that the user requests the change of the communication protocol. For example, the user uses the input device of the host device 12 to instruct whether or not there is a communication protocol change request.

Of course, the host device 12 may automatically determine whether or not the communication protocol definition file has been changed. For example, when the communication protocol definition file does not define a communication protocol that can be used by the host device 12, the host device 12 determines to change the communication protocol definition file. On the other hand, when the communication protocol definition file defines a communication protocol that can be used by the host device 12, the host device 12 determines not to change the communication protocol definition file. Further, the host device 12 may store information indicating the communication protocol designated by the user. In this case, when the communication protocol defined in the communication protocol definition file is different from the communication protocol specified by the user, the host device 12 determines to change the communication protocol definition file. On the other hand, when the communication protocol defined in the communication protocol definition file is the same as the communication protocol specified by the user, the host device 12 determines to change the communication protocol definition file.

The host device 12 transmits information indicating the presence/absence of a request to change the communication protocol definition file to the radiation measuring apparatus 10 using a communication medium that can be used by the host device 12 (S11). When the change of the communication protocol definition file is requested, the host device 12 performs radiation measurement on the changed communication protocol definition file itself or the data representing the changed communication protocol (for example, ID as a communication protocol identifier). Send to device 10. The changed communication protocol definition file itself or the data representing the changed communication protocol is, for example, data designated or created by the user of the host device 12. For example, when the default communication protocol ID is “00a” and the host device 12 does not support the communication protocol of ID “00a” but the communication protocol of ID “00b”. The host device 12 transmits the character string “00b” as the ID of the communication protocol to the radiation measuring apparatus 10.

When the external transmission unit 22 of the radiation measuring apparatus 10 receives the information indicating the presence/absence of the request for changing the communication protocol definition file from the host apparatus 12, the external transmission section 22 uses the communication medium that the host apparatus 12 can use and sends a reply indicating that the request has been received. Is transmitted to the host device 12 (S12).

When the change of the communication protocol definition file is requested, the control unit 42 of the radiation measurement apparatus 10 changes the definition content of the communication protocol definition file in response to the change request from the host device 12. For example, when the changed communication protocol definition file itself is transmitted from the host device 12 to the radiation measurement apparatus 10, the control unit 42 sets the default communication protocol definition file stored in the storage unit 40 to the changed communication Replace with the protocol definition file. When data representing the content of the changed communication protocol (for example, an ID as a communication protocol identifier) is transmitted from the host apparatus 12 to the radiation measuring apparatus 10, the control unit 42 causes the communication stored in the storage unit 40. Change the definition contents of the protocol definition file to the changed communication protocol. When the change of the communication protocol definition file is not requested, the definition content of the default communication protocol definition file stored in the storage unit 40 is maintained without being changed.

In the above example, the data file configuration definition file, the communication medium definition file, and the communication protocol definition file are separately transmitted from the radiation measurement device 10 to the host device 12. However, the data file configuration definition file, the communication Definition files including the medium definition file and the communication protocol definition file may be transmitted from the radiation measurement apparatus 10 to the host apparatus 12 at once.

Next, the measurement unit 20 transmits a data packet including the measurement data and the ID as the data identifier to the external transmission unit 22 (S13).

The data file generation unit 36 of the external transmission unit 22 generates a data file having the measurement data (data entity) in the data packet transmitted from the measurement unit 20 as a file element according to the data file configuration definition file (S14). .. When the default data file configuration definition file is maintained, the data file generation unit 36 generates a data file according to the default data file configuration definition file. When the default data file configuration definition file is changed and the changed data file configuration definition file is stored in the storage unit 40, the data file generation unit 36 creates the data file according to the changed data file configuration definition file. To generate.

The external communication unit 38 of the external transmission unit 22 uses the communication medium defined in the communication medium definition file to transmit the data file to the host device 12 according to the communication protocol defined in the communication protocol definition file ( S15). When the default communication medium definition file is maintained, the external communication unit 38 transmits the data file to the host device 12 using the default communication medium. When the default communication medium definition file is changed and the changed communication medium definition file is stored in the storage unit 40, the external communication unit 38 uses the changed communication medium to copy the data file to the host device 12. Send to. When the default communication protocol definition file is maintained, the external communication unit 38 transmits the data file to the host device 12 according to the default communication protocol. When the default communication protocol definition file is changed and the changed communication protocol definition file is stored in the storage unit 40, the external communication unit 38 transmits the data file to the host device 12 according to the changed communication protocol. ..

As described above, according to the present embodiment, the definition files (data file configuration definition file, communication medium definition file, communication protocol definition file) are changed in response to a change request from the host device 12, and the changed definition file A data file is generated according to the above, and the data file is transmitted to the host device 12. As described above, according to this embodiment, it is possible to flexibly meet the request of the host device 12. For example, the format of the data file, the communication medium, and the communication protocol may be changed for the convenience of operation of the radiation measurement system. According to this embodiment, it is possible to flexibly deal with the change. For example, an ID as a data identifier, an ID as a communication medium identifier, and an ID as a communication protocol identifier are used as common IDs in the radiation measurement apparatus 10 and the host apparatus 12, and in response to a request from the host apparatus 12. , The definition file is changed dynamically.

Further, according to the present embodiment, since the radiation measurement apparatus 10 and the host apparatus 12 use a common ID, by referring to the ID when the radiation measurement apparatus 10 fails, the investigation time and maintenance time can be shortened. Can be expected.

Further, according to the present embodiment, the definition file stored in the radiation measuring apparatus 10 can be rewritten by remote operation from the host device 12. Thereby, it becomes possible to rewrite the definition files stored in the plurality of radiation measuring apparatuses 10 set in various places by remote operation from the host apparatus 12. Therefore, the time required for the rewriting can be shortened. In addition, it becomes possible for the operator to rewrite the definition file by remote operation without actually going to the radiation measurement site where human intervention is not desired.

In the embodiment described above, the control unit 42 of the external transmission unit 22 may prohibit modification of the definition content of the definition file in an emergency. In an emergency, for example, the measured radiation value (for example, dose rate) becomes equal to or higher than a preset threshold value. For example, even if the host device 12 requests the modification of the definition file, the control unit 42 prohibits modification of the definition content of the definition file.

In an emergency, the data file generation unit 36 of the external transmission unit 22 may generate a data file according to a preset emergency data file configuration definition file. The data file configuration definition file for emergency is a definition file that is created in advance and stored in the storage unit 40, and the modification of the definition content is prohibited. For example, even if the definition content of the default data file configuration definition file is changed, in an emergency, the data file generation unit 36 does not use the changed data file configuration definition file and Generate a data file according to the data file configuration definition file. As a result, a data file including measurement data for determining the situation in an emergency is generated, and the data file is transmitted to the host device 12.

In an emergency, the external communication unit 38 of the external transmission unit 22 transmits the data file to the host device 12 using the communication medium defined in the communication medium definition file for emergency set in advance. Good. The communication medium definition file for emergency is a definition file that is created in advance and stored in the storage unit 40, and the modification of the definition content is prohibited. For example, even if the definition content of the default communication medium definition file is changed, in an emergency, the external communication unit 38 does not use the changed communication medium but uses the emergency communication medium. Then, the data file is transmitted to the host device 12. The emergency communication medium is, for example, a communication medium capable of more reliable communication, and specifically, satellite communication or the like. For example, even if the changed communication medium is a wireless LAN, in an emergency, the data file is transmitted to the host device 12 using satellite communication. Thereby, in an emergency, the data file is transmitted to the host device 12 more reliably.

In an emergency, the external communication unit 38 of the external transmission unit 22 may transmit the data file to the host device 12 according to the communication protocol defined in the communication protocol definition file for emergency set in advance. The communication protocol definition file for emergencies is a definition file that is created in advance and stored in the storage unit 40, and the modification of the definition content is prohibited. For example, even when the definition content of the default communication protocol definition file is changed, in an emergency, the external communication unit 38 does not follow the changed communication protocol but the data file according to the emergency communication protocol. Is transmitted to the host device 12. The emergency communication protocol is, for example, a protocol in which the transmission frequency of the data file is maximized, and specifically, a protocol in which the data file is transmitted once per minute. As another example, when the data transmission frequency according to the communication protocol currently adopted is lower than the data transmission frequency according to the emergency communication protocol, the external communication unit 38 causes the emergency communication to be performed during the emergency. The data file may be transmitted to the host device 12 according to the protocol. On the other hand, when the frequency of data transmission by the communication protocol adopted at present is higher than the frequency of data transmission by the communication protocol for emergency, the external communication unit 38 is currently adopted even in emergency. The data file may be transmitted to the host device 12 according to the communication protocol. As a result, in an emergency, more data files are transmitted to the host device 12 to determine the situation.
