Embodiments for Carrying Out the Invention

[0010] Embodiments for carrying out the present disclosure will be described with reference to the accompanying drawings. In each figure, the same or corresponding parts are denoted by the same reference numerals. Redundant descriptions of such parts will be simplified or omitted as appropriate.

[0011] Embodiment 1. FIG. 1 is a block diagram of the control panel test system in Embodiment 1.

[0012] In FIG. 1, a control panel 10 of an elevator to be the subject of an operation test is shown. For example, the control panel 10 is provided in a test room of a building (not shown). The control panel 10 includes an overall control unit 11 and a motor control unit 12.

[0013] The overall control unit 11 is provided so as to be able to control the overall operation in the elevator system. Specifically, the overall control unit 11 is provided so as to be able to detect that operation buttons such as buttons provided at the elevator landing and buttons provided in the elevator car are pressed. The overall control unit 11 is provided so as to be able to control the overall operation of the elevator, such as the ascending and descending operation of the car and the opening and closing operation of the door provided in the car.

[0014] The motor control unit 12 is provided so as to be able to control the elevator motor. Specifically, the motor control unit 12 is provided so as to be able to output a motor input signal for controlling the operation of the hoist motor of the elevator based on a control command from the overall control unit 11. For example, the motor control unit 12 includes a drive unit (not shown) such as a drive circuit for driving the motor. The motor control unit 12 is provided so as to be electrically connected to the motor.

[0015] The control panel test system 20 is provided in the same test room as the control panel 10. The control panel test system 20 is provided so as to be able to conduct an operation test of the control panel 10. The control panel test system 20 includes a motor simulation device 21, an operation simulation device 22, a storage device 23, a display device 24, a test device 25, and an automatic operation device 26.

[0016] The motor simulation device 21 is electrically connected to the motor control unit 12 of the control panel 10. The motor simulation device 21 is provided so as to be able to simulate the electrical response of the elevator motor based on a model such as a motor model.

[0017] Specifically, the motor simulation device 21 includes an AD conversion circuit (not shown), a computing device, and a DA conversion circuit. The AD conversion circuit can receive the input of the voltage of the motor input signal from the motor control unit 12. The AD conversion circuit can convert the voltage of the motor input signal, which is an analog signal, into a digital input signal. For example, the computing device includes devices such as a personal computer, a microcontroller board, an FPGA board, etc. The computing device can perform operations that simulate the response of the motor on the digital input signal converted by the AD conversion circuit. The computing device can generate a digital output signal indicating the operation result that simulates the response of the motor. The DA conversion circuit can convert the digital output signal from the computing device into an analog signal. The DA conversion circuit can generate a motor output signal, which is an analog signal indicating the digital output signal. The DA conversion circuit can output the motor output signal to the motor control unit 12.

[0018] The operation simulation device 22 is provided so as to be able to output signals output from operation panels such as the landing operation panel and the car operation panel of the elevator. Specifically, the operation simulation device 22 is provided so as to be able to receive an input that simulates the operation performed on the operation panel. The operation simulation device 22 is provided so as to be able to output an operation simulation signal corresponding to the received input.

[0019] The storage device 23 stores the model information of the control panel 10, the test information about the operation test of the control panel 10, and the result information of the operation test.

[0020] For example, the display device 24 is a liquid crystal display device. The display device 24 is provided so as to be able to display information.

[0021] For example, the test device 25 is composed of computing devices such as a PLC (Programmable Logic Controller), a personal computer, a microcontroller board, an FPGA board, etc. The test device 25 is electrically connected to the overall control unit 11 of the control panel 10. The test device 25 is connected to the motor simulation device 21, the operation simulation device 22, the storage device 23, and the display device 24 in the control panel test system 20. For example, the test device 25 can automatically determine whether there are manufacturing defects such as functional defects of each device constituting the control panel 10 and assembly defects of the control panel 10 according to the specified judgment criteria based on the procedure of the operation test.

[0022] For example, the automatic operation device 26 is composed of a computing device. The automatic operation device 26 is connected to the operation simulation device 22 and the test device 25.

[0023] The automatic operation device 26 conducts an operation test by sending commands to the operation simulation device 22 and the test device 25 based on the procedure of the operation test.

[0024] Specifically, for example, the automatic operation device 26 conducts an operation test on the landing operation panel of the elevator. When an operator performs an operation to conduct the operation test on the test device 25, the automatic operation device 26 starts the operation test. In the operation test, the automatic operation device 26 sends a command to the operation simulation device 22 to simulate the input operation of a specific button on the landing operation panel. The operation simulation device 22 outputs an operation simulation signal simulating the signal output by the landing operation panel when the specific button is pressed. The test device 25 receives the operation simulation signal output by the operation simulation device 22 and outputs a control signal corresponding to the specific button to the control panel 10.

[0025] When the control panel 10 receives a control signal from the test device 25, it performs an operation to allocate the elevator car corresponding to the signal. The control panel 10 outputs a motor input signal for driving the motor to the motor simulation device 21 based on the operation of allocating the car. The motor simulation device 21 performs an operation to simulate the operation of the motor based on the motor input signal, and transmits the motor output signal to the control panel 10 and the test device 25.

[0026] The test device 25 acquires signals related to the operation from the motor simulation device 21, the operation simulation device 22, and the control panel 10. In the operation test, the test device 25 monitors the operation of the control panel 10 based on the acquired signals. The test device 25 determines whether the operation of the control panel 10 satisfies the specified judgment criteria, that is, whether the operation test is qualified or unqualified.

[0027] When the test device 25 completes one operation test, the automatic operation device 26 ends the automatic operation of the operation test.

[0028] After that, for example, when there are items that fail in the operation test, the operator investigates the cause of the failure.

[0029] Next, with reference to FIGS. 2 and 3, information about the operation test will be described. FIG. 2 is a diagram showing information stored in the storage device of the control panel test system in Embodiment 1. FIG. 3 is a block diagram of the storage device of the control panel test system in Embodiment 1.

[0030] As shown in FIG. 2, the storage device 23 stores a model information DB 23a, a procedure information DB 23b, and a result information DB 23c (DB: DataBase).

[0031] The model information DB 23a is a database in which model information is stored. The model information is information in which information on "model number", information on "model function", information on "number of floors", and information on "rated speed" are associated.

[0032] The information of "model number" is the information for identifying the control panel 10 to be tested. The information of "model function" is the information indicating the functions provided for the elevator in which the control panel 10 is to be installed. The information of "model function" is the information indicating different functions for each building where the elevator is installed. Specifically, for example, the information of "model function" is the specification information of the earthquake detection device provided for the elevator. The information of "number of floors" is the information indicating the number of floors of the building where the elevator is installed. The information of "rated speed" is the information indicating the rated speed of the car set for the elevator.

[0033] The procedure information DB23b is a database storing test information. The test information is the information in which the information of "model number", the information of "test item", and the information of "test procedure for each item" are associated.

[0034] The information of "test item" is the information indicating individual items for which tests are conducted in the operation test. In one operation test, one or more test items are set. The information of "test procedure for each item" is the information indicating the procedure for conducting the test of the individual item in the operation test. For example, the information of "test procedure for each item" is the information such as the content of the work instruction that the operator should perform and the content of the operation to be input to the operation simulation device 22 when conducting a certain individual item test. In one test item, one or more test procedures are set.

[0035] The result information DB23c is a database storing test result information indicating the results of the operation test. The test result information is the information in which the information of "model number", the information of "test device number", the information of "test time", the information of "test pass / fail", and the information of "detailed test result" are associated.

[0036] The information of "test device number" indicates the device number for identifying the test device 25 on which the operation test was performed. The information of "test time" indicates the date and time when the operation test was conducted. The information of "test pass / fail" indicates whether the control panel 10 passed or failed the operation test. The information of "test result details" indicates the detailed results of the operation test.

[0037] Figure 3 shows an overview of the information exchange between the storage device 23, the test device 25, and the automatic operation device 26.

[0038] When starting the operation test, the operator activates the test device 25. The test device 25 starts the initial settings.

[0039] In the initial settings, the test device 25 obtains the model number information from the control panel 10. The test device 25 obtains the test condition information corresponding to the model number information from the storage device 23. Specifically, when obtaining the test condition information, first the test device 25 obtains the model information corresponding to the model number of the control panel 10 from the storage device 23 as the first test condition information. Then, the test device 25 obtains the test information corresponding to the model information from the storage device 23 as the second test condition information. The test device 25 sets the test procedure based on the obtained test information. For example, the test procedure is the procedure such as the timing and order in which specific inputs should be given to the operation simulation device 22 in the test items of the operation test. When the test device 25 sets the test procedure, it ends the initial settings.

[0040] The automatic operation device 26 detects that the test device 25 has completed the initial settings. In this case, the automatic operation device 26 obtains the model information and the set test procedure information from the test device 25.

[0041] Based on the model information and the test procedure information, the automatic operation device 26 determines whether to perform each of one or more test items defined for one operation test. When the automatic operation device 26 determines to perform a test item, it sends a command to the operation simulation device 22 or the test device 25 to output a specific signal for each test procedure so that the input defined by the test procedure included in the test item is performed.

[0042] When the automatic operation device 26 determines not to perform a test item, or when the implementation of a certain test item is completed, it determines whether to perform the next test item. When the automatic operation device 26 determines whether to perform or not perform all the test items defined for one operation test, it ends the operation test.

[0043] Next, with reference to FIG. 4, the content displayed on the display device 24 will be described. FIG. 4 is a diagram showing the content displayed on the display device of the control panel test system in the first embodiment.

[0044] The test device 25 causes the display device 24 to display content related to the operation test.

[0045] As shown in FIG. 4, on the display device 24, a car state display section 24a, a landing state display section 24b, a button operation display section 24c, and a test information display section 24d are displayed.

[0046] In the car state display section 24a, information indicating the operation state of the car simulatedly calculated by the control panel 10 in the operation test is displayed. Specifically, in the car state display section 24a, information indicating the position of the car in the simulated up and down directions, the speed of the simulated car, the content displayed on the internal indicator of the simulated car, etc. is displayed.

[0047] In the landing status display section 24b, information indicating the operating status of the landing simulated by the control panel 10 in the operation test is displayed. Specifically, in the landing status display section 24b, information indicating the simulated opening / closing status of the landing door, the content displayed on the simulated landing indicator, etc. is displayed.

[0048] In the button operation display section 24c, information corresponding the operation simulation signal output by the operation simulator 22 to the actual device is displayed. Specifically, for example, in the test of the landing operation panel, in the button operation display section 24c, it is displayed which button on which landing operation panel the operation simulator 22 is simulating to output a signal.

[0049] In the test information display section 24d, information indicating the content of the operation test is displayed. Specifically, in the test information display section 24d, information indicating the test items, the procedures for each item, the pass / fail within the test items, etc. is displayed.

[0050] Next, the operation test will be described with reference to FIG. 5. FIG. 5 is a flowchart for explaining the outline of the operation test performed by the control panel test system in the first embodiment.

[0051] As shown in FIG. 5, by starting the test device 25 connected to the control panel 10, the operator starts the operation test.

[0052] In step S01, the test device 25 acquires the information of the model number of the control panel 10 from the control panel 10.

[0053] Thereafter, the operation of step S02 is performed. In step S02, the test device 25 acquires the information of the test conditions corresponding to the model number, the information of the test items corresponding to the model number, and the information of the test procedures for each item corresponding to the test item from the storage device 23. The test device 25 sets the test procedures based on the received information of the test procedures for each item.

[0054] After that, the operation of step S03 is performed. In step S03, after the operator confirms from the content displayed on the display device 24 that the test conditions have been set, the control panel 10 and the motor simulation device 21 are connected with a test cable.

[0055] After that, the operation of step S04 is performed. In step S04, the automatic operation device 26 acquires the model information and the information of the set test procedure from the test device 25. The automatic operation device 26 starts the automatic operation by sending an input command to the operation simulation device 22.

[0056] After that, the operation of loop 1 from step S05 to step S08 is performed. In step S05, the automatic operation device 26 determines the number of test items based on the information of the test items. The automatic operation device 26 calculates the number of times n that loop 1 has been executed. For example, in the operation test, when the test item is executed for the first time, the automatic operation device 26 performs an operation where the number of times n that loop 1 has been executed is 1. If the automatic operation device 26 determines that the value of n is less than or equal to the number of test items, loop 1 is executed.

[0057] As loop 1, the operation of step S06 is performed. In step S06, the automatic operation device 26 determines whether it is necessary to execute the nth test item, which has the same value as the value n calculated in the previous step S05, based on the information of the model function and the information of the procedure for each item.

[0058] If, in step S06, the automatic operation device 26 determines that it is necessary to execute the nth test item, as loop 1, the operation of step S07 is performed. In step S07, the automatic operation device 26 causes the operation simulation device 22 and the test device 25 to execute the test item.

[0059] After the operation in step S07 is completed, or when it is determined in step S06 that the automatic operation device 26 does not need to execute the nth test item, as loop 1, the operation in step S08 is performed. In step S08, the automatic operation device 26 determines whether all the set test items have been executed or do not need to be executed, that is, whether the number of loop iterations n is greater than or equal to the number of test items.

[0060] If it is determined in step S08 that the number of loop iterations n is less than the number of test items, the automatic operation device 26 adds 1 to the number of loop iterations. Then, the automatic operation device 26 performs the operations after step S05 which is loop 1.

[0061] If it is determined in step S08 that the number of loop iterations n is greater than or equal to the number of test items, the operation in step S09 is performed. In step S09, the automatic operation device 26 ends the automatic operation as an operation to end loop 1. The test device 25 causes the display device 24 to display information indicating that the automatic operation has ended.

[0062] After that, the operation in step S10 is performed. In step S10, the operator removes the test cables connected to the control panel 10 and the motor simulation device 21, and the test cables connected to the control panel 10 and the test device 25.

[0063] After that, the operation in step S11 is performed. In step S11, the test device 25 stores the test result information in the storage device 23.

[0064] After that, the operation test ends.

[0065] According to the first embodiment described above, the control panel test system 20 includes an operation simulation device 22, a test device 25, and an automatic operation device 26. The automatic operation device 26 outputs a signal to the operation simulation device 22 based on a defined operation test procedure. The test device 25 performs an operation test on the control panel 10 based on the signal input by the operation simulation device 22 to the control panel 10. Therefore, in the operation test, the work of the operator to operate the operation simulation device 22 based on the test procedure can be omitted. As a result, the efficiency of the test can be improved.

[0066] In addition, the control panel test system 20 includes a motor simulation device 21. The motor simulation device 21 outputs to the control panel 10 the result of simulating the operation of the motor connected to the control panel 10. Therefore, in the operation test, the operator can omit the work of preparing the actual motor corresponding to the control panel 10. As a result, the efficiency of the test can be improved.

[0067] In addition, the control panel test system 20 includes a storage device 23 and a display device 24. The storage device 23 stores the information necessary for the operation test. The display device 24 displays the information related to the operation test. Therefore, in the operation test, the operator can recognize the test information.

[0068] In addition, in the control panel test system 20, the model information, the test information, and the test result information are stored. The test device 25 sets a test procedure corresponding to the control panel 10 based on the model information and the test information. The test device 25 stores the result of the operation test in the storage device 23 as the test result information. Therefore, the test device 25 can automatically set a test procedure corresponding to the conditions under which the control panel 10 is installed. The test device 25 can leave the test result.

[0069] In addition, on the display device 24 of the control panel test system 20, a car state display portion 24a, a landing state display portion 24b, a button operation display portion 24c, and a test information display portion 24d are displayed. Therefore, the control panel test system 20 can inform the operator of the state of the operation being simulated in the operation test. The operator can proceed with the work while checking the current situation of the operation test.

[0070] Note that the operation simulation device 22 may be composed of a personal computer, a display, a keyboard, and a mouse. The display may display information simulating the operation panel.

[0071] Note that the test device 25 may be a device that performs sequence control.

[0072] Note that during the operation test, before the test device 25 is started, the control panel 10 and the motor simulation device 21 may be connected by a test cable. In this case, in the flowchart shown in FIG. 5, the operation in step S03 may be omitted.

[0073] Note that in the operation test, the operator may manually perform the test procedure that the automatic operation device 26 causes the operation simulation device 22 and the test device 25 to execute without using the automatic operation device 26. In this case, the operator operates the operation simulation device 22 while checking the screen of the display device 24.

[0074] Next, with reference to FIG. 6, an example of the hardware constituting the test device 25 will be described in detail. FIG. 6 is a hardware configuration diagram of the test device of the control panel test system in Embodiment 1.

[0075] Each function of the test device 25 can be realized by a processing circuit. For example, the processing circuit includes at least one processor 100a and at least one memory 100b. For example, the processing circuit includes at least one dedicated hardware 200.

[0076] When the processing circuit includes at least one processor 100a and at least one memory 100b, each function of the test apparatus 25 is realized by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is described as a program. At least one of the software and the firmware is stored in at least one memory 100b. The at least one processor 100a realizes each function of the test apparatus 25 by reading and executing the program stored in the at least one memory 100b. The at least one processor 100a is also referred to as a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, or a DSP. For example, the at least one memory 100b is a non-volatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, or a DVD.

[0077] When the processing circuit includes at least one dedicated hardware 200, the processing circuit is realized by, for example, a single circuit, a composite circuit, a programmed processor, a parallel-programmed processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the test apparatus 25 is realized by the processing circuit respectively. For example, each function of the test apparatus 25 is realized by the processing circuit collectively.

[0078] Regarding each function of the test apparatus 25, a part may be realized by the dedicated hardware 200 and the other part may be realized by software or firmware. For example, the function of storing the test result information in the storage device 23 is realized by a processing circuit as the dedicated hardware 200, and the functions other than the function of storing the test result information in the storage device 23 may be realized by the at least one processor 100a reading and executing the program stored in the at least one memory 100b.

[0079] In this way, the processing circuit realizes each function of the test device 25 in hardware 200, software, firmware, or a combination thereof.

[0080] Although not shown, each function of the motor simulation device 21, each function of the operation simulation device 22, each function of the storage device 23, and each function of the automatic operation device 26 are also realized by a processing circuit equivalent to the processing circuit that realizes each function of the test device 25.

[0081] Embodiment 2. FIG. 7 is a block diagram of the main part of the control panel test system in Embodiment 2. In addition, the same reference numerals are given to the same or corresponding parts as those in Embodiment 1. The description of that part is omitted.

[0082] In Embodiment 2, the control panel test system 20 includes an analysis device 27.

[0083] For example, the analysis device 27 is composed of a computing device such as a personal computer and a display device. The analysis device 27 is connected to the storage device 23.

[0084] The analysis device 27 acquires test result information regarding one or more operation tests out of the most recent operation test and past operation tests from the result information DB 23c of the storage device 23. The analysis device 27 analyzes the acquired test result information and displays the analyzed result on the display device.

[0085] The analysis device 27 analyzes the test result information using a plurality of methods and displays the analyzed result in a plurality of ways.

[0086] Specifically, for example, the analysis device 27 analyzes and calculates the average value, median value, etc. of the time required for the tests of the test items implemented on a certain day, based on the information on the time elapsed until the completion of the test for each test item included in the test result information. After that, the analysis device 27 creates a graph in which the values such as the average value and median value of the analyzed elapsed time are taken on the vertical axis and the date on which the test was implemented is taken on the horizontal axis. The analysis device 27 displays the graph on the display device.

[0087] For example, the analysis device 27 compares the results of analyzing and calculating two pieces of corresponding test result information for two operation tests implemented by a certain test device 25 (not shown) and another test device 25 (not shown), to determine whether an abnormality has occurred in any of the test devices 25. When the analysis device 27 determines that an abnormality has occurred in any of the test devices 25, it displays the determination result on the display device.

[0088] According to the second embodiment described above, the control panel test system 20 includes the analysis device 27. The analysis device 27 compares the current operation test with past operation tests based on the past test result information stored in the storage device 23. The analysis device 27 displays the analyzed content of the comparison on the screen. For this reason, the control panel test system 20 can visualize the results regarding the operation test. The control panel test system 20 can compare the past operation test with the current operation test. As a result, the operator can early detect that an abnormality has occurred in the control panel test system 20, the environment of the operation test, etc. Specifically, the operator can early detect an abnormality such as a high failure occurrence ratio in a specific operation test, an abnormality such as an increase in the time required to execute a specific operation test, etc. Further, since the content of the abnormality is visualized, the operator can take appropriate measures against the abnormality.

[0089] Note that the analysis device 27 may determine whether an abnormality has occurred not only for two test devices 25 but also for one or three or more test devices 25.

[0090] Although not shown, each function of the analysis device 27 may also be realized by a processing circuit equivalent to the processing circuit that realizes each function of the test device 25.

[0091] The analysis device 27 may cause the display device 24 to display the result of analyzing the test result information.

[0092] The analysis device 27 may create graphs classified by model number, operator identification number, etc. Thus, abnormalities occurring during the operation test, trends regarding the operation test, etc. can be analyzed in more detail.

[0093] The analysis device 27 may create a graph having a horizontal axis organized by month or year instead of by date. Thus, trends regarding operation tests that change over a longer time interval can be observed.

[0094] The analysis device 27 may create a graph showing the number of times a test item failed instead of the time required for the test. Thus, information such as test items with a large number of failures, test devices with failures, model numbers of the control panels 10 with failures, etc. can be identified. Also, when the cause of the failure of the test item does not result from a defect in the control panel 10, the cause of the failure can be analyzed. Also, countermeasures can be taken against the cause of the failure. As a result, the occurrence of failures not due to defects in the control panel 10 in the test can be suppressed, the efficiency of the operation test can be improved. Also, the defect detection accuracy in the operation test can be improved. Also, the test time in the operation test can be shortened.

[0095] The analysis device 27 may create a table arranging in order the test items with a large number of failures for each test device 25 or for each model number of the control panel 10. The analysis device 27 may display the table on the display device. Thus, countermeasures can be taken in the order of the number of failures.

[0097] In Embodiment 3, the control panel test system 20 includes a power cable 30 and a repeater 31.

[0098] The power cable 30 is connected to the control panel 10 and the test device 25. The power cable 30 is provided so as to be able to supply power serving as power from the test device 25 to the control panel 10. For example, the power cable 30 is a cable used for a three-phase AC power supply, a three-phase motor, etc.

[0099] The repeater 31 is provided so as to be able to transmit signals between the control panel 10 and the test device 25 as a test cable. The repeater 31 has a plurality of branch cables 32, a first connector 33, and a plurality of second connectors 34.

[0100] The plurality of branch cables 32 are cables for transmitting signals. Each of the plurality of branch cables 32 has connection pins at both ends.

[0101] The shape of the first connector 33 is formed to correspond to the connection portion 25a of the test device 25. The first connector 33 is provided at one end of the plurality of branch cables 32. The first connector 33 gathers a plurality of connection pins in the plurality of branch cables 32 into one. The first connector 33 is connected to the connection portion 25a of the test device 25.

[0102] The shapes of the plurality of second connectors 34 are formed to correspond to the plurality of connection parts 10a of the control panel 10 respectively. Each of the plurality of second connectors 34 is provided at the other end of the plurality of branch cables 32. Each of the plurality of second connectors 34 bundles together a number of branch cables 32 equal to the number of pins of the connection part 10a of the corresponding control panel 10 among the plurality of branch cables 32. Each of the plurality of second connectors 34 bundles together the connection pins of the corresponding number of branch cables 32 into one. The plurality of second connectors 34 are respectively connected to the corresponding connection parts 10a in the control panel 10.

[0103] Next, with reference to FIG. 9, a conventional repeater when compared with the repeater 31 will be described. FIG. 9 is a diagram showing an example of a conventional repeater connected to the control panel test system in Embodiment 3.

[0104] As shown in FIG. 9, in the conventional example, as the power cable 30, a cable similar to the power cable in Embodiment 3 can be applied. In the conventional example, the plurality of conventional repeaters 35 are connected to the control panel 10 and the conventional test device 25. The plurality of conventional repeaters 35 each have a number of branch cables corresponding to the shape and the number of pins of the plurality of connection parts 10a of the control panel 10. Each of the plurality of conventional repeaters 35 has a number of connection pins equal to the number of branch cables at both ends.

[0105] In the conventional example, the conventional test device 25 includes a plurality of connection parts 25b corresponding to the plurality of conventional repeaters 35. Therefore, conventionally, it has been necessary to prepare the plurality of conventional repeaters 35 and the conventional test device 25 corresponding to the shape and the number of pins of the connection part 10a of the control panel 10. Also, conventionally, an operator has had to connect each of the plurality of conventional repeaters 35 to the conventional test device 25 while checking the connector name printed on the connector of the conventional repeater 35 and the connector name printed on the connection part 25b of the conventional test device 25. On the other hand, the repeater 31 not shown in FIG. 9 of Embodiment 3 is connected to the test device 25 by connecting the first connector 33 to one connection part 25a of the test device 25.

[0106] According to the third embodiment described above, the control panel test system 20 includes a repeater 31. In the repeater 31, a plurality of second connectors 34 correspond to the connection part 10a of the control panel 10. By manufacturing various repeaters 31 corresponding to control panels 10 of various models, an operation test can be performed on the control panels 10 of various models using one test device 25. As a result, the test device 25 can be standardized regardless of the model of the control panel 10.
