As will be described later, the responder 50 transmits a response signal from the UHF transmission circuit 58 on a trial basis according to the instructions of the test apparatus 80. Therefore, starting power is required regardless of whether the security gate 200 is actually used in the active type or the passive type.

The control device 30, the responder 50, and the test device 80 construct a communication establishment test system 10 in a broad sense. The broad sense refers to the system configuration including the responder 50. At this time, it can be said that the responder 50 and the test device 80 are combined to form the test device 150 with a responder. The control device 30 and the test device 80 construct a communication establishment test system 160 in a narrow sense.

Further, when viewed from the test device 80, it can be said that the interrogator 210 and the control device 30 are constructing the interrogator 170 with a control device. In any case, the communication establishment test is performed on the premise that the communication establishment test system 10, the responder 50, and the communication establishment test system 160 operate without any problem.

In FIG. 2, the processors 32, 52, 82, 212, the memories 34, 54, 84, 214, and the like are conceptually described as computer hardware. Each device may include a plurality of processors, a plurality of memories, and the like. In FIG. 2, the plurality of processors, the plurality of memories, and the like are grouped together, and conceptually, the processors 32, 52, 82, 212, and the memory 34 are provided. Note that it is expressed as, 54, 84, 214, and so on.

Subsequently, with reference to FIG. 3, the functional configuration constructed in each device will be described. The functions to be constructed include those related to the first test, that is, those related to the transmission of the authentication signal by the interrogator 210, and those related to the second test, that is, those related to the reception of the response signal by the interrogator 210. In the following, the configuration related to the first test may be named "first", and the function related to the second test may be named "second".

In the interrogator 210, a communication record sharing unit 230 and an authentication unit 232 are constructed 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 via communication by a wired connection.

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

The response signal receiving unit 236 is an example of the response signal receiving means, and the responder 50 placed in the authentication area 206 receives the response signal transmitted by the radio in the UHF band. The second test confirms the reception state of the response signal B18, which is experimentally transmitted by the responder 50 from the authentication area 206, in the response signal receiving unit 236. The authentication unit 232 is also an example of an authentication means, and has an authentication processing function of collating the ID included in the response signal B18 with the registered ID. However, the certification processing function is not tested in the first test and the second test.

In the control device 30, a second count unit 40 and a questioner control unit 42 are constructed by hardware and software. When the second test is carried out, 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. Typically, in the second test, reception of the response signal B18 is attempted a plurality of times, so that the second counting unit 40 counts the total number of receptions. The counted response signal reception number B24 is an example of reception status information in the interrogator 210, and is transmitted to the test apparatus 80 through communication using Wi-Fi.

The interrogator control unit 42 controls the interrogator 210 by receiving instructions from the test device 80 via Wi-Fi and transmitting the corresponding instructions to the interrogator 210 via wired communication, and controls the interrogator 210 for the first test and the second test. To be carried out. Specifically, the interrogator control unit 42 receives the first test start instruction A12 from the test device 80, and issues the authentication signal transmission instruction A14 to the authentication signal transmission unit 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 unit 42 receives the first test start instruction A12 from the test device 80 and issues the authentication signal transmission instruction A14 to the authentication signal transmission unit 234 each time. This facilitates synchronization of transmission and reception of the authentication signal A16. However, the interrogator control unit 42 collectively receives instructions regarding the number of transmissions of the authentication signal A16 and the time interval at the start of the first test, and issues the authentication signal transmission instruction A14 to the authentication signal transmission unit 234 each time according to the instructions. It is also possible.

Further, when the interrogator control unit 42 receives the second test start instruction B12 from the test device 80, the interrogator control unit 42 transmits the response signal reception instruction B14 to the response signal reception unit 236. Further, the interrogator control unit 42 acquires the response signal reception record B20 from the communication record sharing unit 230 after the set time has elapsed, and causes the second counting unit 40 to count the response signal reception record B20. At the end of the second test, the interrogator control unit 42 receives the second test result transmission instruction B22 from the test device 80. In this case, the interrogator control unit 42 instructs the second counting unit 40 to transmit the number of times the response record is received to the test apparatus 80.

The response device 50 is constructed with a first start button 70, an authentication signal reception unit 72, a response signal transmission unit 74, and a second start button 76 by hardware and software. The first start button 70 is constructed by using the physical operation button 60, and is used for the operator 300 to instruct the start of the first test. When the first start button 70 is pressed, the first start button pressing signal A10 is transmitted to the test device 80, and the test device 80 starts the first test.

The authentication signal receiving unit 72 receives the authentication signal transmitted by the LF band radio by the authentication signal transmitting unit 234 of the interrogator 210. In the first test, when the authentication signal receiving unit 72 receives the authentication signal A16 transmitted on a trial basis, the authentication signal receiving signal A18 is transmitted to the test device 80. In the normal case, the reception of the authentication signal is a trigger for transmitting the response signal. That is, when the responder 50 receives the authentication signal, the response signal transmission unit 74 transmits the response signal. In the first test, when the authentication signal A16 is received, the response signal may be transmitted from the response signal transmission unit 74, but it may not be transmitted. When transmitting the response signal in the first test, the responder 50 may transmit the response signal transmission signal indicating that the response signal has been transmitted to the test apparatus 80 instead of the authentication signal reception signal A18. ..

The response signal transmission unit 74 transmits a response signal by radio 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 apparatus 80.

The second start button 76 is constructed by using the physical operation button 60, and is used for the operator 300 to instruct the start of the second test. When the second start button 76 is pressed, the second start button pressing signal B10 is transmitted to the test device 80, and the test device 80 starts the second test.

Depending on the hardware and software, the test apparatus 80 includes a test setting unit 100, a first start instruction unit 102, a first count unit 104, a first determination unit 106, a display unit 108, a second start instruction unit 110, and a second. The determination unit 112 is constructed.

The test setting unit 100 performs a process for starting the first test and the second test based on the operation of the touch panel 86 application by the operator 300. Examples of the items to be set include the number of transmissions of the authentication signal A16 in the first test, the transmission interval, the determination reference value, the number of transmissions of the response signal B18 in the second test, the transmission interval, the determination reference value, and the like. Default values can be used for these items without any special settings. In addition, the test setting unit 100 performs preliminary communication with the control device 30 to confirm that the Wi-Fi communication is operating normally. When the test setting unit 100 is ready to start the first test, the test setting unit 100 sets a start flag for the first test and displays on the touch panel 86 that the preparation is complete. When the first test is completed, the completion flag of the first test is set and the touch panel 86 indicates the completion.

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

The first determination unit 106 is an example of the first determination means, and performs determination processing based on the result of the first test. The first determination unit 106 inputs the number of times the authentication signal transmission instruction A14 has been transmitted from the first start instruction unit 102, and also inputs the number of times the authentication signal A16 has been received from the first count unit 104. As a result, the first determination unit 106 calculates the ratio of the number of receptions to the number of transmissions, and compares the calculated ratio with the preset reference value. The first determination unit 106 determines that the communication establishment related to the authentication signal A16 has been successful when the calculated ratio is equal to or greater than the reference value, and determines that the communication establishment has failed if the calculated ratio is less than the reference value. The calculated ratio, the determination result, and the like are displayed on the display unit 108 using the touch panel 86, and are appropriately stored in the memory 84 of the test apparatus 80. The test apparatus 80 may record or display only the calculated ratio without performing the determination by the first determination unit 106, and entrust the determination work to the operator 300.

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

The second determination unit 112 is an example of the second determination means, and the number of times the response signal is transmitted is input from the second start instruction unit 110, and the number of times the response signal is received B24 is input from the second count unit 40 of the control device 30. To do. Then, the second determination unit 112 calculates the ratio of the number of receptions to the number of transmissions 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. The test apparatus 80 may record or display only the calculated ratio without performing the determination by the second determination unit 112, and entrust the determination work to the operator 300.

Subsequently, 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 signal flow in the test device 80, the control device 30, the interrogator 210, and the responder 50 along the downward time axis.

Prior to the test, the worker 300 connects the control device 30 to the interrogator 210 by wire. Further, the worker 300 connects the test device 80 to the response device 50 by wire, holds the response device 50 and the test device 80 in his / her hand, and stands at the measurement position. The measurement position may be, for example, one place in the assumed authentication area 206, or may be several places in the assumed authentication area 206. Further, the measurement position can be set outside the assumed authentication area 206.

The operator 300 operates the touch panel 86 of the test apparatus 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 responder 50 to the test device 80.

When the test apparatus 80 inputs the first start button pressing signal A10, the test apparatus 80 first executes the n = first process. Specifically, the first start instruction unit 102 transmits the first test start instruction A12 to the interrogator control unit 42 of the control device 30. Further, the first start instruction unit 102 increases the number of transmissions of the authentication signal A16 held as an internal variable by 1 from the initial value of zero (S14). The interrogator control unit 42 transmits the authentication signal transmission instruction A14 to the authentication signal transmission unit 234 of the interrogator 210. The authentication signal transmission unit 234 that has input the authentication signal transmission instruction A14 transmits the authentication signal A16 by radio 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 unit 72 of the responder 50 receives the authentication signal A16 and transmits the authentication signal receiving signal A18 to the first counting unit 104 of the test apparatus 80. .. On the other hand, when the strength of the authentication signal A16 is weak or the authentication signal A16 is not transmitted, the authentication signal receiving unit 72 cannot receive the authentication signal A16, and the first counting unit 104 receives the authentication signal reception signal. Do not send A16.

The first count unit 104 of the test apparatus 80 waits for the input of the authentication signal reception signal A18 until a predetermined time elapses after the first test start instruction A12 is issued. Then, when the authentication signal reception signal A18 is input, the first count unit 104 increments the working variable held inside by 1 from the initial value of zero, and the authentication signal reception signal A18 is not input. The working variable is left at zero, which is the initial value (S16). As a result, the n = first process is completed.

Similarly, the n = 2, 3, 4, ... th processing is performed, and the n = Nth processing, which is the finally set number of times, is completed (N is a positive integer). At this time, the transmission count N is input from the first start instruction unit 102 to the first determination unit 106 of the test apparatus 80, and the reception count L (L is a positive integer less than or equal to N) is input from the first count unit 104. Will be done. The first determination unit 106 calculates the L / N and makes a determination by comparing with the reference value (S18). If the L / N is equal to or higher than the reference value, the first determination unit 106 determines that the communication establishment of the authentication signal A16 by the LF band has been successful, and causes the display unit 108 to display the success. On the other hand, if the L / N is less than the reference value, it is determined that the communication establishment has failed, and the display unit 108 displays the fact of the failure.

Subsequently, the flow of the second test will be described with reference to FIG. FIG. 5 is a sequence diagram in the second test. FIG. 5 shows the signal flow in the test device 80, the control device 30, the interrogator 210, and the responder 50 along the downward time axis in the same manner as in FIG.

The second test is usually performed consecutively after the first test is performed. In the example shown in FIG. 5, the display unit 108 of the test apparatus 80 indicates 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 responder 50 to start the second test (S22). At this time, the second start button 76 transmits the second start button pressing signal B10 to the second start instruction unit 110 of the test apparatus 80.

When the second start button pressing signal B10 is input to the test apparatus 80, first, m = first processing is performed. Specifically, the second start instruction unit 110 transmits the second test start instruction B12 to the interrogator control unit 42 of the control device 30. The interrogator control unit 42 transmits the response signal reception instruction B14 to the response signal reception unit 236 of the interrogator 210.

The second start instruction unit 110 transmits the response signal transmission instruction B16, which is a transmission instruction of the experimental response signal B18, to the response signal transmission unit 74 of the response device 50. As a result, the response signal transmission unit 74 transmits the response signal B18 by radio in the UHF band. Further, the second start instruction unit 110 increases the number of transmissions, 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 receiving unit 236 is operating correctly. When the response signal reception unit 236 receives the response signal B18, the response signal reception record B20 is transmitted from the communication record sharing unit 230 to the second count unit 40 of the control device 30. In the second count unit 40, the internal variable is incremented by 1 from the initial value of zero (S26). On the other hand, if the response signal receiving unit 236 is not operating correctly, or if the responder 50 is outside the authentication area 206, the response signal receiving unit 236 cannot receive the response signal B18. Therefore, when the predetermined time has elapsed, the response signal reception record B20 indicating that the response signal is not received is input to the second count unit 40. The second count unit 40 maintains the initial value at zero. As a result, the m = first process is completed.

In the same manner, the m = 2, 3, 4, ... th processing is performed, and the m = M th processing, which is the finally set number of times, is completed (M is a positive integer). At this time, the second start instruction unit 110 of the test apparatus 80 transmits the second test result transmission instruction B22 to the interrogator control unit 42. Then, the response signal reception number B24 counted by the second count unit 40 of the control device 30 is transmitted to the second determination unit 112. The number of transmissions M is input from the second start instruction unit 110 to the second determination unit 112, and the number of receptions K (K is a positive integer less than or equal to M) is input from the second count unit 40. The second determination unit 112 calculates K / M and makes a determination by comparing with the reference value (S28). If the K / M is equal to or higher than the reference value, it is determined that the communication establishment of the response signal B18 by the UHF band has been successful, and the success is displayed on the display unit 108. On the other hand, if the K / M is less than the reference value, it is determined that the communication establishment has failed, and the display unit 108 displays the fact of the failure.

The worker 300, for example, conducts a test 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, the worker 300 can confirm the success or failure of the communication establishment of the authentication signal only by pressing the first start button 70, except for the preparatory work. Further, the worker 300 can confirm the success or failure of the communication establishment of the response signal only by pressing the second start button 76. In the first test and the second test, even when a large number of repetitions are performed, the time required for one process is very short, so that the worker 300 as a whole can set the communication establishment state in a short time. Can be grasped. Further, in general, the communication by Wi-Fi is longer than the transmission distance of the LF band radio and the UHF band radio transmission distance at the security gate 200. Therefore, even when the measurement position is set outside the authentication area 206, the first test and the second test can be easily performed.

In particular, since the security gate 200 is used by a plurality of users, it is assumed that the direction of approaching the security gate 200, the waiting position in front of the security gate 200, and the like differ depending on the user. Therefore, since there is a high possibility that the worker 300 will move to a plurality of measurement points and perform measurement, the confirmation work will be made more efficient by using the communication establishment test system 10.

The embodiment can be changed in various ways. For example, in the above description, the first start button 70 and the second start button 76 are constructed by using the physical operation button 60 included in the responder 50. However, the first start button 70 and the second start button 76 can be provided in the test apparatus 80 instead of the responder 50. For example, there is an example in which the first start button 70 and the second start button 76 are displayed on the touch panel 86 of the test apparatus 80.

The test device 150 with a response device may use an integrated device instead of connecting the response device 50 and the test device 80, which are made of different housings, by wire. As an example, there is an embodiment in which a tablet, a smartphone or the like capable of LF band wireless reception, UHF band wireless transmission and Wi-Fi wireless communication is used as the responder 50. In this case, an application for constructing a function as the test device 80 may be installed on the tablet or smartphone.
The control device 30 and the interrogator 210 can be set to be wirelessly connected instead of the wired connection. Further, the responder 50 and the test device 80 can be set to be wirelessly connected instead of the wired connection. In these cases, the wireless communication method used for the wireless connection is not particularly limited as long as the communication is surely established.

In the above description, the LF band wireless communication method is mentioned as the first wireless communication method, the UHF band wireless communication method is mentioned as the second wireless communication method, and the Wi-Fi wireless communication method is mentioned as the third communication method. .. However, the wireless communication method can be changed in various ways. The first wireless communication system, the second wireless communication system, and the third wireless communication system may have at least different communication standards, and may have overlapping frequency bands, for example. However, as the third wireless communication system, a system having a longer communication distance than the first wireless communication system and the second wireless communication system 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.

The establishment of wireless communication can be determined not by the ratio of the number of successful receptions but by other indicators. For example, there is an embodiment of confirming the degree of matching of information such as characters and numbers carried by an authentication signal or a response signal.
