[0002] The alarm module of the controller refers to a module unit that sends an alarm response signal in response to an abnormal situation when an abnormality occurs in the device connected to the controller or the controller itself. Usually, when an abnormality occurs in the device connected to the controller, the device itself or the sensor used to detect the operating status of the device will send an alarm signal to the alarm module in the controller. After receiving the alarm signal, the alarm module will send an alarm response signal to the warning unit according to the alarm type signal, so that the warning unit will issue an alarm through sound and light.

[0024] As mentioned above, since the alarm module usually only sends an alarm response signal when the device or controller connected to the controller has an abnormality, and in some cases artificially causing the device or controller to have an abnormality will cause great losses, a new test device is urgently needed to test the alarm module.

[0026] It should be noted that the various drawings in the specification of this application are only used to facilitate the explanation and understanding of this embodiment, and are not intended to be any limitation to this application. They are not necessarily drawn according to the actual scale.
[0027] The test equipment provided in the embodiments of the application is primarily used to test the alarm module of a controller in electrical equipment. For example, the alarm module can be tested during the production process of the electrical equipment, during on-site installation and commissioning of the electrical equipment, or after an on-site upgrade of the electrical equipment. The controller may include a processing unit such as a PLC (Programmable Logic Controller) or a CPU (Central Processing Unit).
[0028] The test equipment provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0029] like Figure 1 As shown, the alarm module 100 of the controller 10 includes an alarm input unit 110 and an alarm output unit 120. The alarm input unit 110 includes a signal input terminal 111, and the alarm output unit 120 includes a power supply terminal 121 and a signal output terminal 122. The first connection port 130 of the controller 10 includes a first terminal 131, a second terminal 132, and a third terminal 133. The signal input terminal 111 of the alarm input unit 110 is connected to the first terminal 131 of the first connection port 130, so that the alarm input unit 110 receives an external analog test signal provided via the first terminal 131 through the signal input terminal 111. The power supply terminal 121 of the alarm output unit 120 is connected to the second terminal 132 of the first connection port 130, so that the power supply terminal 121 supplies power to the second terminal 132. The power supply terminal 121 can be used as a redundant power supply for the alarm output unit 120. The signal output terminal 122 of the alarm output unit 120 is connected to the third connection terminal 133 of the first connection port 130 , so that the signal output terminal 122 can provide an alarm response signal to the third connection terminal 133 .
[0030] In some optional embodiments, the controller of the test equipment provided in the application embodiments may be the controller of a T2000AP (automation processor) cabinet. The alarm input unit 110 may be the SIM421 module in the T2000AP cabinet, and the alarm output unit 120 may be the SIM422 module in the T2000AP cabinet. The specific structures of the T2000AP cabinet, SIM421 module, and SIM422 module can be referenced in related art and will not be further described here. By using the controller of a T2000AP cabinet in the application embodiments, the alarm module of the T2000AP cabinet controller can be tested to detect any abnormalities in the alarm module of the T2000AP cabinet controller.
[0031] The test device 200 provided in an embodiment of the present application includes: a signal simulation circuit 210, an alarm simulation circuit 220, and a second connection port 230 for detachably connecting to the first connection port 130. The second connection port 230 includes a fourth connection terminal 231 connected to the output end of the signal simulation circuit 210, a fifth connection terminal 232 connected to the input end of the signal simulation circuit 210, and a sixth connection terminal 233 connected to the alarm simulation circuit 220.
[0032] When testing the alarm module 100 using the test device 200, the second connection port 230 is connected to the first connection port 130. Specifically, the fourth terminal 231 of the second connection port 230 is connected to the first terminal 131 of the first connection port 130, and the fifth terminal 232 of the second connection port 230 is connected to the second terminal 132 of the first connection port 130. As a result, the power supply terminal 121 supplies power to the signal simulation circuit 210 via the second terminal 132 and the fifth terminal 232. The signal simulation circuit 210 outputs an analog alarm signal to the first terminal 131 via the fourth terminal 231, triggering the alarm module 100 to output an alarm response signal from the signal output terminal 122. The sixth terminal 233 of the second connection port 230 is connected to the third terminal 133 of the first connection port 130. The power supply terminal 121 can supply 24V, thereby providing a 24V power supply to the signal simulation circuit 210.
[0033] If the alarm simulation circuit 220 receives an alarm response signal from the signal output end 122 output by the third terminal 133 through the sixth terminal 233, the analog module included in the alarm simulation circuit 220 presents a first state to indicate that the alarm module 100 is working normally; if the alarm simulation circuit 220 does not receive the alarm response signal, the analog module included in the alarm simulation circuit 220 presents a second state to indicate that there is an abnormality in the alarm module 100.
[0034] It should be noted that there are many situations in which the alarm simulation circuit 220 does not receive the alarm response signal. One is that the signal output terminal 122 does not output the alarm response signal. At this time, the alarm module 100 may have an abnormality, or there is an abnormality in the connection between the signal input terminal 111 of the alarm input unit 110 and the first terminal 131 of the first connection port 130. In addition, if the signal simulation circuit 210 does not receive power, the alarm simulation circuit 220 will not receive the alarm response signal; the second is that the signal output terminal 122 outputs the alarm response signal, but the alarm simulation circuit 220 does not receive the alarm response signal. At this time, there may be an abnormality in the connection between the signal output terminal 122 of the alarm output unit 120 and the third terminal 133 of the first connection port 130.
[0035] As a feasible implementation, the input end of the alarm simulation circuit 220 can be connected to the third terminal 133 through the sixth terminal 233, and the output end of the alarm simulation circuit 220 can be connected to a 0V voltage end having a voltage of 0V or to a grounded voltage end. The 0V voltage end or the grounded voltage end to which the output end of the alarm simulation circuit 220 is connected can be a circuit element of the test device 200 itself, or a circuit element in the controller 10 that is connected to a terminal of the first connection port 130. It should be understood that when the 0V voltage end or the grounded voltage end is a circuit element in the controller 10 that is connected to a terminal of the first connection port 130, the output end of the alarm simulation circuit 220 can be connected to the ground terminal corresponding to the 0V voltage end or the grounded voltage end in the first connection port 130 through the ground terminal of the second connection port 230.
[0036] The first state presented by the analog module may be a state such as sounding or emitting light, and the second state presented may be a state such as no sounding or no light. Alternatively, the first state presented by the analog module may be a state such as no sounding or no light, and the second state presented may be a state such as sounding or light. As a feasible implementation, the analog module may be an oscilloscope, and the first state presented by the analog module corresponds to a state in which the oscilloscope detects an alarm response signal, and the second state presented by the analog module corresponds to a state in which the oscilloscope does not detect an alarm response signal. It should be understood that this application does not limit the specific forms of the first state and the second state, as long as the first state and the second state are different.
[0037] The simulated alarm signal generated by the signal simulation circuit 210 can simulate an alarm condition without having to artificially create an alarm condition that triggers the alarm module 100 to output an alarm response signal, thereby avoiding losses caused by abnormalities in the electrical equipment or controller 10. It should be understood that the "alarm condition" in the embodiments of the present application refers to an abnormal condition that can trigger the alarm module 100 to output an alarm response signal, such as an electrical equipment trip or excessive temperature.
[0038] In the prior art, after receiving an alarm signal, the alarm module 100 can generate a corresponding alarm response signal based on the alarm signal, and output the alarm response signal through the signal output terminal 122. The alarm response signal can enable the alarm unit connected to the controller 10 to give an alarm through sound, light, etc. However, during the production or debugging of the controller 10, the alarm module 100 of the controller 10 may not be connected to the alarm unit in some cases. In this case, it is impossible to judge whether the alarm unit can normally output the alarm response signal based on the alarm status of the alarm unit. The signal simulation circuit 210 of the embodiment of the present application can output an alarm simulation signal consistent with the alarm signal, the alarm simulation circuit 220 can receive the alarm response signal, and the simulation module included in the alarm simulation circuit 220 can present a first state and a second state respectively when the alarm response signal is received and when the alarm response signal is not received, so that the user can judge whether the alarm module 100 has an abnormality based on the state presented by the simulation module.
[0039] In addition, in order to test whether a power outage or tripping can normally trigger the alarm module 100 to output an alarm response signal in the prior art, it is usually necessary to power off the electrical equipment to which the controller 10 belongs. However, frequent power on and off can easily cause damage or failure to the components in the electrical equipment. The test device 200 provided in the embodiment of the present application can generate a simulated alarm signal corresponding to a power outage or tripping through the signal simulation circuit 210, and output the simulated alarm signal to the first terminal 131 connected to the signal input terminal 111 of the alarm module 100, so that when the signal input terminal 111 of the alarm module 100 receives the simulated alarm signal, the alarm module 100 can be triggered to output an alarm response signal without having to power off the electrical equipment to which the controller 10 belongs, thereby avoiding damage or failure to the electrical equipment. In addition, the test device 200 of the embodiment of the present application can be used for on-site testing after upgrading and modification of electrical equipment, during which the alarm situation is simulated by the simulated alarm signal, and the test of the alarm module 100 of the controller 10 can be completed without affecting the normal operation of the electrical equipment, which can effectively improve the efficiency of the test and save the time used for on-site testing.
[0040] In an embodiment of the present application, the test device 200 includes a signal simulation circuit 210, an alarm simulation circuit 220, and a second connection port 230 for detachably connecting to the first connection port 130; the second connection port 230 includes a fourth connection terminal 231 connected to the output end of the signal simulation circuit 210, a fifth connection terminal 232 connected to the input end of the signal simulation circuit 210, and a sixth connection terminal 233 connected to the alarm simulation circuit 220. When the alarm module 100 is tested using the test device 200, the fourth terminal 231 of the second connection port 230 is connected to the first terminal 131 of the first connection port 130, and the fifth terminal 232 of the second connection port 230 is connected to the second terminal 132 of the first connection port 130, so that the power supply terminal 121 supplies power to the signal simulation circuit 210 through the second terminal 132 via the fifth terminal 232, and the signal simulation circuit 210 outputs a simulated alarm signal to the first terminal 131 through the fourth terminal 231, which is used to trigger the alarm module 100 to output an alarm response signal from the signal output terminal 122, thereby simulating the occurrence of an alarm situation, so as to trigger the alarm module 100 to output an alarm response signal through the signal output terminal 122, and judge whether the alarm module 100 has an abnormality by the state presented by the simulation module included in the alarm simulation circuit 220, without having to artificially cause the device connected to the controller 10 or the controller 10 to have an abnormal situation corresponding to the alarm situation, thereby avoiding the loss caused by the abnormal situation.
[0041] like Figure 2 As shown, in some optional embodiments, the alarm input unit 110 includes multiple signal input terminals 111, and one signal input terminal 111 among the multiple signal input terminals 111 is used to receive an alarm signal triggered by one of multiple alarm situations, that is, each signal input terminal 111 only corresponds to receiving an alarm signal triggered by one alarm situation, and the alarm module 100 can determine the type of alarm situation that triggered the alarm signal based on the signal input terminal 111 that receives the alarm signal.
[0042] Various alarm conditions may include damage to the cooling fan of electrical equipment, excessive temperature, insufficient power supply voltage, etc. Different alarm conditions can be detected by different detection circuits. A signal input terminal 111 can be provided for each alarm condition, and the signal input terminal 111 is connected to the detection circuit for detecting the alarm condition. The above-mentioned multiple signal input terminals 111 can be connected to different detection circuits. When each detection circuit detects an alarm condition, it can output an alarm signal to the signal input terminal 111 connected to the detection circuit to trigger the alarm module 100 to output an alarm response signal.
[0043] The first connection port 130 may include a plurality of first connection terminals 131 , and one of the plurality of signal input terminals 111 is connected to one of the plurality of first connection terminals 131 .
[0044] The signal simulation circuit 210 may include multiple analog sub-circuits 211, and the second connection port 230 may include multiple fourth connection terminals 231, one of the multiple fourth connection terminals 231 is connected to one of the multiple analog sub-circuits 211. The input end of the signal simulation circuit 210 may include the input end of the analog sub-circuit 211, and the output end of the signal simulation circuit 210 may include the output end of the analog sub-circuit 211. The amplification structure of the first connection port 130 and the second connection port 230 can be seen in FIG. Figure 3 .
[0045] When the alarm module 100 is tested using the test equipment 200, one of the plurality of fourth terminals 231 is connected to one of the plurality of first terminals 131, and at least one of the plurality of analog sub-circuits 211 outputs an analog alarm signal to the first terminal 131 via the fourth terminal 231. Furthermore, the analog alarm signal output by one of the plurality of analog sub-circuits 211 is the same as the alarm signal triggered by one of the plurality of alarm conditions, so that the analog alarm signal output by the analog sub-circuit 211 simulates the occurrence of an alarm condition.
[0046] It should be understood that the alarm simulation signal output to the first terminal 131 can be consistent with the alarm signal output to the signal input terminal 111 connected to the first terminal 131, thereby simulating the alarm condition detected by the detection circuit connected to the signal input terminal.
[0047] In an embodiment of the present application, the signal simulation circuit 210 may include multiple analog sub-circuits 211, and the second connection port 230 includes multiple fourth terminals 231, one of the multiple fourth terminals 231 is connected to one of the multiple analog sub-circuits 211, and when the alarm module 100 is tested using the test equipment 200, one of the multiple fourth terminals 231 is connected to one of the multiple first terminals 131, and each analog sub-circuit 211 can output an analog alarm signal to each first terminal 131 through the connected fourth terminal 231. By using multiple analog sub-circuits 211 to output analog alarm signals, multiple alarm situations can be simulated, so that the test equipment 200 can test the response of the alarm module 100 when various alarm situations occur, thereby more comprehensively testing the performance of the alarm module 100.
[0048] like Figure 4 As shown, in some optional embodiments, the analog sub-circuit 211 includes an analog switch 212; Figure 5 and 6As shown, when the alarm module 100 is tested using the test equipment 200 , the analog switches 212 included in the multiple analog sub-circuits 211 are in a closed state, and the analog alarm signal is output to the first terminal 131 through the connected fourth terminal 231 .
[0049] In the embodiment of the present application, the analog sub-circuit 211 may include an analog switch 212. When the alarm module 100 is tested using the test equipment 200, the analog switch 212 may be closed or opened to control whether the analog sub-circuit 211 including the analog switch 212 outputs an analog alarm signal to the first terminal 131 via the fourth terminal 231.
[0050] The analog sub-circuits 211 can be controlled more flexibly, and the response of the alarm module 100 to various alarm situations can be tested through the analog sub-circuits 211 .
[0051] In some optional embodiments, when the alarm module 100 is tested using the test device 200 , one analog sub-circuit 211 among the plurality of analog sub-circuits 211 outputs an analog alarm signal to the first connection terminal 131 through the second connection port 230 .
[0052] As a feasible implementation, by closing only the analog switch 212 of one analog sub-circuit 211, only the analog sub-circuit 211 can output the analog alarm signal to the first connection terminal 131 through the second connection port 230, such as Figure 5 As shown, only the analog switch 212 of the topmost analog sub-circuit 211 may be closed.
[0053] When only one analog sub-circuit 211 outputs an analog alarm signal to the first connection terminal 131 through the second connection port 230 , the response of the alarm module 100 when only one alarm condition occurs can be tested, thereby improving the pertinence of the test on the alarm module 100 .
[0054] In some optional embodiments, when the alarm module 100 is tested using the test device 200 , two or more analog sub-circuits 211 among the plurality of analog sub-circuits 211 output analog alarm signals to the first connection terminal 131 through the second connection port 230 .
[0055] As a feasible implementation, by closing the analog switches 212 of two or more analog sub-circuits 211 at the same time, the two or more analog sub-circuits 211 can output analog alarm signals to the first connection terminal 131 through the second connection port 230, such as Figure 6 As shown, the analog switches 212 of the top five analog sub-circuits 211 can be closed simultaneously.
[0056] When two or more analog sub-circuits 211 output analog alarm signals to the first terminal 131 through the second connection port 230, the reaction of the alarm module 100 when multiple alarm conditions occur simultaneously can be tested by the test equipment 200, so that a comprehensive judgment can be made on whether there is an abnormality in the alarm module 100 by combining multiple alarm conditions.
[0057] The alarm signals triggered by various alarm situations may be the same, that is, the analog alarm signals output by multiple analog sub-circuits 211 may be the same. In this case, the structure of the analog sub-circuit 211 may be as described in the following embodiment.
[0058] like Figure 4-6 As shown, in some optional embodiments, the first end of the analog switch 212 of the analog sub-circuit 211 is connected to the fourth terminal 231 of the second connection port, and the second end of the analog switch 212 is connected to the fifth terminal 232 of the second connection port. In this case, the output end of the analog sub-circuit 211 can be the first end of the analog switch 212, and the input end of the analog sub-circuit 211 can be the second end of the analog switch 212.
[0059] The analog alarm signal output by the analog subcircuit 211 is an electrical signal output by the first terminal of the analog switch 212 when the analog switch 212 is closed. That is, the analog alarm signal in the embodiment of the present application can be a voltage signal and / or a current signal output by the first terminal of the analog switch 212.
[0060] In an embodiment of the present application, the first end of the analog switch 212 of the analog sub-circuit 211 is connected to the fourth terminal 231 of the second connection port, and the second end of the analog switch 212 is connected to the fifth terminal 232 of the second connection port. The electrical signal output by the first end of the analog switch 212 when the analog switch 212 is closed can be directly used as an analog alarm signal without the need to set up additional equipment for generating the analog alarm signal, which can simplify the circuit structure of the analog sub-circuit 211.
[0061] In some optional embodiments, the simulation module includes an alarm indicator light. When the simulation module is in a first state, the alarm indicator light is in a light-emitting state; when the simulation module is in a second state, the alarm indicator light is in a non-light-emitting state.
[0062] It should be understood that the alarm response signal outputted by the signal output terminal 122 of the alarm module 100 is an electrical signal, and the alarm indicator light is an indicator light that can emit light when driven by the electrical signal.
[0063] In this embodiment of the present application, the simulation module includes an alarm indicator light. When the simulation module is in a first state, the alarm indicator light is illuminated; when the simulation module is in a second state, the alarm indicator light is not illuminated. Thus, when the signal output terminal 122 outputs an alarm response signal, the alarm indicator light illuminates to indicate the state of the simulation module, thereby visualizing the alarm response signal and enabling the user to easily and conveniently determine whether the signal output terminal 122 has output an alarm response signal.
[0064] As a feasible implementation method, the simulation module may also include a sound-emitting device such as a buzzer. When the simulation module is in the first state, the buzzer is in a sounding state; when the simulation module is in the second state, the buzzer is in a silent state. Therefore, when an alarm response signal is received, it is possible to determine whether the signal output terminal 122 has output an alarm response signal by whether the sound-emitting device makes a sound.
[0065] In some optional embodiments, the test device 200 provided in the present application may further include a third connection port for connecting to a power source other than the power terminal 121 , and the third connection port is connected to an input terminal of the signal simulation circuit 210 .
[0066] The third connection port and the second connection port 230 can supply power to the signal simulation circuit 210 together. Alternatively, the test device 200 may further include a power selection switch, which is used to select one of the third connection port and the fifth connection terminal 232 of the second connection port 230 to be connected to the input end of the signal simulation circuit 210, thereby selectively supplying power to the signal simulation circuit 210 through the third connection port or the second connection port 230.
[0067] In an embodiment of the present application, the test device 200 may also include a third connection port for connecting to a power source other than the power supply terminal 121, and the third connection port is connected to the input terminal of the signal simulation circuit 210, so that when there is an abnormality in the power supply of the power supply terminal 121, other power sources can be connected through the third connection port to power the signal simulation circuit 210, which can better ensure the normal operation of the test device 200.
