Next, with reference to FIG. 3, the functional configuration constructed in each device will be described. The functions to be constructed relate to the first test, ie the transmission of the authentication signal by the Interrogator 210, and the second test, ie the reception of the response signal by the Interrogator 210. Hereinafter, the configuration related to the first test may be named "first", and the function related to the second test may be named "second".

A communication record sharing unit 230 and an authentication unit 232 are constructed in the interrogator 210 by hardware and software. The communication record sharing unit 230 records the communication performed by the interrogator 210 and transmits the record to the external device. The communication record sharing unit 230 can share records with, for example, a building management system. In the second test, the communication record sharing unit 230 shares the response signal reception record B20 with the control device 30 through wired communication.

The authentication unit 232 performs authentication processing in the security gate 200 . The authentication section 232 is provided with an authentication signal transmission section 234 and a response signal reception section 236 . The authentication signal transmission unit 234 is an example of authentication signal transmission means, and periodically transmits an authentication signal according to a predetermined protocol using LF band radio. The transmitted authentication signal is received by transponder 50 located in authentication area 206 . In the first test, a test authentication signal A16 is transmitted from the authentication signal transmitting section 234 to confirm whether or not it can actually be received in the authentication area 206 .

The response signal receiving unit 236 is an example of response signal receiving means, and receives a response signal transmitted wirelessly in the UHF band from the transponder 50 placed in the authentication area 206 . In the second test, the response signal B18 transmitted from the authentication area 206 by the transponder 50 on a trial basis is checked by the response signal receiving section 236 for receiving the response signal B18. Note that the authentication unit 232 is also an example of authentication means, and has an authentication processing function of matching the ID included in the response signal B18 with the registered ID. However, the authentication processing function is not tested in the first test and the second test.

A second counting section 40 and an interrogator control section 42 are constructed in the control device 30 by hardware and software. The second counting unit 40 receives the response signal reception record B20 from the communication record sharing unit 230 of the interrogator 210 and counts the number of receptions when conducting the second test. Typically, the second test attempts to receive the response signal B18 a plurality of times, so the second counting unit 40 counts the total number of receptions. The counted response signal reception count B24 is an example of reception status information in the interrogator 210, and is transmitted to the test device 80 through communication using Wi-Fi.

The interrogator control unit 42 receives an instruction from the test device 80 via Wi-Fi, and controls the interrogator 210 by transmitting a corresponding instruction to the interrogator 210 through wired communication. be implemented. Specifically, the interrogator control section 42 receives the first test start instruction A12 from the test device 80 and issues an authentication signal transmission instruction A14 to the authentication signal transmission section 234 . In the first test, the test authentication signal A16 is typically transmitted multiple times. In the embodiment, it is assumed that the interrogator control section 42 receives the first test start instruction A12 from the test device 80 each time, and issues an authentication signal transmission instruction A14 to the authentication signal transmission section 234 . This facilitates synchronization of transmission and reception of the authentication signal A16. However, the interrogator control unit 42 collectively receives an instruction regarding the number of transmissions of the authentication signal A16 and the time interval at the start of the first test, and according to the instruction, issues an authentication signal transmission instruction A14 to the authentication signal transmission unit 234 each time. is also possible.

Further, when the interrogator control section 42 receives the second test start instruction B12 from the test device 80, the interrogator control section 42 transmits a response signal reception instruction B14 to the response signal reception section 236. FIG. After the set time has passed, the interrogator control section 42 acquires the response signal reception record B20 from the communication record sharing section 230 and causes the second counting section 40 to count. At the end of the second test, the interrogator control section 42 receives a second test result transmission instruction B22 from the test device 80. FIG. In this case, the interrogator control section 42 instructs the second counting section 40 to transmit the response record reception frequency to the testing apparatus 80 .

A first start button 70, an authentication signal receiver 72, a response signal transmitter 74, and a second start button 76 are constructed in the transponder 50 by hardware and software. The first start button 70 is constructed using the physical operation button 60 and is used by the operator 300 to instruct the start of the first test. When the first start button 70 is pressed, a first start button pressing signal A10 is transmitted to the testing device 80, and the testing device 80 starts the first test.

The authentication signal receiving section 72 receives the authentication signal transmitted wirelessly in the LF band by the authentication signal transmitting section 234 of the interrogator 210 . In the first test, the authentication signal receiving section 72 transmits an authentication signal reception signal A18 to the test device 80 when receiving the authentication signal A16 transmitted on a trial basis. Note that reception of the authentication signal usually triggers transmission of the response signal. That is, when the responder 50 receives the authentication signal, the response signal transmitting section 74 transmits the response signal. In the first test, when the authentication signal A16 is received, the response signal transmitting section 74 may transmit a response signal, but it does not have to be transmitted. When transmitting a response signal in the first test, the responder 50 may transmit a response signal transmission signal indicating that the response signal has been transmitted to the test device 80 instead of the authentication signal reception signal A18. .

The response signal transmission unit 74 transmits a response signal wirelessly in the UHF band. In the second test, the response signal B18 is transmitted each time the response signal transmission instruction B16 is received from the test device 80. FIG.

A second start button 76 is constructed using the physical operation button 60 and is used by the operator 300 to indicate the start of the second test. When the second start button 76 is pressed, a second start button press signal B10 is sent to the testing device 80, and the testing device 80 starts the second test.

The test apparatus 80 includes a test setting section 100, a first start instructing section 102, a first counting section 104, a first determining section 106, a display section 108, a second start instructing section 110, a second A determination unit 112 is constructed.

The test setting unit 100 performs processing for starting the first test and the second test based on the operation of the application on the touch panel 86 by the operator 300 . Items to be set include, for example, the number of transmissions of the authentication signal A16 in the first test, the transmission interval, and the criterion value, and the number of transmissions of the response signal B18 in the second test, the transmission interval, and the criterion value. Default values can also be used for these items without any particular setting. In addition, the test setting section 100 performs preliminary communication with the control device 30 to confirm that Wi-Fi communication is operating normally. When the preparation for starting the first test is completed, the test setting unit 100 sets the start flag for the first test and displays the completion of the preparation on the touch panel 86 . Further, when the first test is completed, the completion flag of the first test is set and the completion is displayed on the touch panel 86 .

The first start instructing unit 102, the first counting unit 104, and the first determining unit 106 are examples of first testing means, and perform processing related to the first test. The first start instructing section 102 instructs the start of the first test according to the setting in the test setting section 100 when the first start button pressing signal A10 is received from the transponder 50 . Specifically, the first start instruction section 102 transmits the first test start instruction A12 to the interrogator control section 42 of the control device 30 each time according to the set number of times of transmission and time interval. When the first counting section 104 receives the authentication signal reception signal A18 from the authentication signal receiving section 72 of the transponder 50 within a predetermined period of time after the first start instruction section 102 issues the first test start instruction A12, to count. That is, the first counting section 104 counts the total number of receptions of the authentication signal A16 during the first test period. The counted number of receptions is an example of reception status information of the authentication signal in the transponder 50 .

The first determination unit 106 is an example of first determination means, and performs determination processing based on the result of the first test. The first determination unit 106 receives from the first start instructing unit 102 the number of transmissions of the authentication signal transmission instruction A14 and also receives from the first counting unit 104 the number of receptions of the authentication signal A16. Accordingly, the first determination unit 106 calculates the ratio of the number of times of reception to the number of times of transmission, and compares the calculated ratio with a preset reference value. The first determination unit 106 determines that the communication establishment related to the authentication signal A16 has succeeded when the calculated ratio is equal to or greater than the reference value, and determines that the communication establishment has failed when the calculated ratio is less than the reference value. The calculated ratio, the determined result, and the like are displayed on the display unit 108 using the touch panel 86 and are also stored in the memory 84 of the test apparatus 80 as appropriate. Note that the test apparatus 80 may record or display only the calculated ratio without performing the determination by the first determination unit 106 , and leave the determination work to the operator 300 .

The second start instruction unit 110 and the second determination unit 112 are examples of second testing means, and perform processing related to the second test. The second start instructing section 110 instructs the start of the second test according to the setting in the test setting section 100 when the second start button pressing signal B10 is received from the transponder 50 . Specifically, the second test start instruction B12 is transmitted to the interrogator control section 42 of the control device 30 each time according to the set number of transmissions and time interval. Also, the second start instructing section 110 transmits a response signal transmission instruction B16 for instructing transmission of a test response signal B18 to the response signal transmission section 74 of the transponder 50 each time. Furthermore, the second start instruction section 110 issues a second test result transmission instruction B22 to the interrogator control section 42 when the series of the second tests is completed.

The second determination unit 112 is an example of second determination means, and receives the number of transmissions of the response signal from the second start instructing unit 110 and the number of times B24 of response signal reception from the second counting unit 40 of the control device 30. do. Then, the second determination unit 112 calculates the ratio of the number of times of reception to the number of times of transmission, and compares it with a preset reference value. The second determination unit 112 determines that the communication establishment related to the response signal B18 has succeeded when the calculated ratio is equal to or greater than the reference value, and determines that the communication establishment has failed when the calculated ratio is smaller than the reference value. The ratio, determination result, etc. are displayed on the display unit 108 using the touch panel 86 . Note that the test apparatus 80 may record or display only the calculated ratio without performing the determination by the second determination unit 112, and leave the determination work to the operator 300. FIG.

Next, the flow of the first test will be described with reference to FIG. FIG. 4 is a sequence diagram in the first test. FIG. 4 shows the flow of signals in the test device 80, the control device 30, the interrogator 210, and the transponder 50 along the downward time axis.

Prior to the test, the operator 300 connects the control device 30 to the interrogator 210 by wire. Also, the operator 300 connects the test device 80 to the responder 50 by wire, holds the responder 50 and the test device 80 in his hand, and stands at the measurement position. The measurement position may be, for example, one point within the assumed authentication area 206 or may be several points within the assumed authentication area 206 . Also, the outside of the assumed authentication area 206 can be set as the measurement position.

The operator 300 operates the touch panel 86 of the test device 80 to confirm that the start flag of the first test is set on the display unit 108 (S10). Then, the worker 300 presses the first start button 70 provided on the responder 50 (S12). As a result, the first start button pressing signal A10 is input from the transponder 50 to the test apparatus 80. FIG.

When the test apparatus 80 receives the first start button pressing signal A10, it first executes the n=1st process. Specifically, the first start instruction section 102 transmits a first test start instruction A12 to the interrogator control section 42 of the control device 30 . Further, the first start instructing unit 102 increases the number of transmissions of the authentication signal A16 held as an internal variable by one from the initial value of zero (S14). The interrogator control unit 42 transmits an authentication signal transmission instruction A14 to the authentication signal transmission unit 234 of the interrogator 210 . After receiving the authentication signal transmission instruction A14, the authentication signal transmission unit 234 transmits an authentication signal A16 wirelessly in the LF band. However, if there is a problem with the interrogator 210, or if the interrogator 210 is not installed properly, the authentication signal A16 may not be transmitted, or may not be transmitted in an appropriate strength or direction.

When the authentication signal A16 is transmitted with sufficient strength, the authentication signal receiving section 72 of the responder 50 receives the authentication signal A16 and transmits the authentication signal reception signal A18 to the first counting section 104 of the test apparatus 80. . On the other hand, when the strength of the authentication signal A16 is weak or when the authentication signal A16 is not transmitted, the authentication signal receiving section 72 cannot receive the authentication signal A16, and the first counting section 104 outputs the authentication signal reception signal. Do not send A16.

The first counting section 104 of the test apparatus 80 waits for the input of the authentication signal reception signal A18 until a predetermined time has passed since the first test start instruction A12 was issued. Then, when the authentication signal reception signal A18 is input, the first counting unit 104 increases the internally held working variable by 1 from the initial value of zero, and when the authentication signal reception signal A18 is not input, , the working variable is left at the initial value of zero (S16). This completes the n=1th process.

Similarly, n=2, 3, 4, . . . , processes are performed, and finally, the set number of times, n=N, is completed (N is a positive integer). At this time, the number of transmissions N from the first start instructing section 102 and the number of receptions L (L is a positive integer equal to or less than N) from the first counting section 104 are input to the first determination section 106 of the test apparatus 80. be done. The first determination unit 106 calculates L/N and performs determination by comparison with a reference value (S18). If L/N is equal to or greater than the reference value, first determination section 106 determines that the communication establishment of authentication signal A16 in the LF band has succeeded, and causes display section 108 to display the success. On the other hand, when the L/N is less than the reference value, it is determined that communication establishment has failed, and the failure is displayed on the display unit 108 .

Next, the flow of the second test will be described with reference to FIG. FIG. 5 is a sequence diagram in the second test. As in FIG. 4, FIG. 5 shows the flow of signals in the test device 80, control device 30, interrogator 210, and responder 50 along the downward time axis.

A second test is usually performed in succession after the first test is performed. In the example shown in FIG. 5, the display unit 108 of the test device 80 displays that the first test completion flag has been set (S20). The first test completion flag also serves as the second test start flag. The operator 300 presses the second start button 76 of the transponder 50 to start the second test (S22). At this time, the second start button depression signal B10 is transmitted from the second start button 76 to the second start instructing section 110 of the test apparatus 80 .

When the test apparatus 80 receives the second start button pressing signal B10, it first performs m=1 processing. Specifically, the second start instruction section 110 transmits a second test start instruction B12 to the interrogator control section 42 of the control device 30 . The interrogator control section 42 transmits a response signal reception instruction B14 to the response signal reception section 236 of the interrogator 210 .

The second start instruction section 110 transmits a response signal transmission instruction B16, which is an instruction to transmit a test response signal B18, to the response signal transmission section 74 of the transponder 50. FIG. Accordingly, the response signal transmission unit 74 transmits the response signal B18 wirelessly in the UHF band. Also, the second start instructing unit 110 increases the number of times of transmission, which is an internal variable, from zero to one (S24).

The interrogator 210 can receive the response signal B18 from within the authentication area 206 when the response signal receiver 236 is operating correctly. When the response signal receiving section 236 receives the response signal B18, the response signal reception record B20 is transmitted from the communication record sharing section 230 to the second counting section 40 of the control device 30. FIG. The second counting unit 40 increments the internal variable by 1 from the initial value of zero (S26). On the other hand, if the response signal receiver 236 does not operate properly, or if the transponder 50 is outside the authentication area 206, the response signal receiver 236 cannot receive the response signal B18. Therefore, after a predetermined time has passed, the response signal reception record B20 indicating that the response signal has not been received is input to the second counting section 40 . The second counting unit 40 maintains an initial value of zero. This completes the m=1st processing.

Similarly, m=2, 3, 4, . . . , processing is performed, and finally the set number of times, m=M, is completed (M is a positive integer). At this time, the second start instruction section 110 of the test device 80 transmits a second test result transmission instruction B22 to the interrogator control section 42 . Then, the response signal reception count B<b>24 counted by the second counting unit 40 of the control device 30 is transmitted to the second determining unit 112 . Second determination section 112 receives transmission count M from second start instructing section 110 and reception count K (K is a positive integer equal to or less than M) from second counting section 40 . The second determination unit 112 calculates K/M and performs determination by comparison with a reference value (S28). If K/M is equal to or greater than the reference value, it is determined that communication establishment of the response signal B18 in the UHF band has succeeded, and the effect of the success is displayed on the display unit 108 . On the other hand, if K/M is less than the reference value, it is determined that the communication establishment has failed, and the failure is displayed on the display unit 108 .

The worker 300, for example, performs tests at a plurality of measurement positions inside and outside the authentication area 206 to grasp the communication establishment state. Then, when the communication is established as expected, the worker 300 removes the control device 30 from the interrogator 210 .

In this way, operator 300 can confirm success or failure of communication establishment of the authentication signal simply by pressing first start button 70, except for preparatory work. Further, the operator 300 can confirm success or failure of establishment of the communication of the response signal only by pressing the second start button 76 . In the first test and the second test, even if a large number of repetitions are performed, the time required for one process is very short. can grasp. In general, Wi-Fi communication is longer than the LF band wireless transmission distance and the UHF band wireless transmission distance at the security gate 200 . Therefore, even when the measurement position is set outside the authentication area 206, it is possible to easily perform the first test and the second test.

In particular, since the security gate 200 is used by a plurality of users, it is assumed that the direction in which the security gate 200 is approached, the waiting position in front of the security gate 200, etc. differ depending on the user. Therefore, the operator 300 is highly likely to move to a plurality of measurement locations and perform measurements, so the use of the communication establishment test system 10 makes the confirmation work more efficient.

Various implementations are possible. For example, in the above description, the first start button 70 and the second start button 76 were constructed using the physical operation buttons 60 provided on the transponder 50 . However, the first start button 70 and the second start button 76 can be provided on the test device 80 instead of the transponder 50 . For example, a first start button 70 and a second start button 76 are displayed on the touch panel 86 of the test device 80 .

The transponder-equipped test apparatus 150 may use an integrated device instead of connecting the transponder 50 and the test apparatus 80, which are separate housings, by wire. One example is a mode in which a tablet, a smartphone, or the like capable of wireless reception in the LF band, wireless transmission in the UHF band, and Wi-Fi wireless communication are used as the transponder 50 . In this case, an application that builds the functions of the test device 80 should be installed on the tablet or smartphone.
Control device 30 and interrogator 210 can be set to be wirelessly connected instead of wired. Also, the transponder 50 and the testing apparatus 80 can be set to be wirelessly connected instead of wired. In these cases, the wireless communication method used for wireless connection is not particularly limited as long as communication can be reliably established.

In the above description, the first wireless communication method is the LF band wireless communication method, the second wireless communication method is the UHF band wireless communication method, and the third wireless communication method is the Wi-Fi wireless communication method. . However, the wireless communication method can be changed in various ways. The first wireless communication method, the second wireless communication method, and the third wireless communication method may have at least different communication standards, and may overlap in frequency bands, for example. However, as the third wireless communication method, one having a longer communication distance than the first wireless communication method and the second wireless communication method is used. This makes it possible to test the establishment of communication even outside the authentication area 206 formed by the first wireless communication system and the second wireless communication system.

Establishment of wireless communication can also be determined by another index instead of the ratio of the number of successful receptions. For example, there is a mode of confirming the degree of matching of information such as alphanumeric characters carried by the authentication signal or the response signal.
