Description

Technical Field

[0001] The present invention belongs to the technical field of signal testing, and particularly relates to a device and method for quickly testing the output signal of equipment. Background Art

[0002] Due to the limitations of the existing product design and structural layout of a certain type of equipment, there are prominent problems in the test phase that some test signals cannot be effectively detected and some faulty functions are difficult to quickly verify. During the equipment test process, it is necessary to monitor and record the parameters of multiple groups of output signals in real time according to the requirements of the test items to evaluate whether they meet the preset indicators. Therefore, achieving fast and accurate signal testing is crucial for the effectiveness of the test. However, dedicated test interfaces are not set for several key output signals of the equipment control device, resulting in the inability to comprehensively obtain the signals required for the test, seriously affecting the test integrity and data reliability.

[0003] To address the problem of missing signal testing, the traditional approach is to use a dedicated tooling cable and manually weld the test line at the equipment plug to connect to an external measuring instrument. Since the number of signals to be measured is large, this method is time-consuming and has a cumbersome process, and is prone to wiring errors due to line confusion, introducing the risk of test data deviation or even equipment failure. In addition, when using the equipment cable for testing, since the test signal cannot be directly led out from the equipment cable, the output signal monitoring link is missing, making it difficult to effectively carry out product debugging and verification work.

[0004] In terms of detecting faulty functions, the existing methods also have problems of complex operation and low efficiency. Taking the fault detection of the firing cable, locking cable, front cable, and rear cable as an example, it is necessary to cut off the power supply of the 28V integrated power supply I and the 28V integrated power supply II successively, disconnect the corresponding firing cable plug and socket, fix and reliably place the disconnected plug, and ensure no overlap with the equipment, that is, isolation from the equipment is required; after re-powering on, observe whether the cable connection fault indicator light turns red through the upper computer interface to judge whether the fault injection is successful. When the indicator light shows red, the fault function of the firing cable can be checked for normal operation. After the detection is completed, it is necessary to cut off the power supply of the 28V integrated power supply I and the 28V integrated power supply II again, correctly plug in the firing cable, re-power on and confirm whether the cable connection fault indicator light returns to green (normal state indication) before it can be determined that the fault function is normal. The fault function tests of the locking cable, front cable, and rear cable all need to be carried out according to the above process, requiring repeated power on / off and cable plugging / unplugging. The operation steps are cumbersome and time-consuming, and frequent power on / off and mechanical plugging may affect the connection reliability and lifespan of the equipment.

[0005] Therefore, there is an urgent need for a systematic solution that can achieve non-invasive, rapid, and accurate test equipment output signals and support one-click fault detection, so as to improve test efficiency and data reliability, while reducing operational complexity and the risk of human error. Summary of the Invention

[0024] This invention also provides a method for rapid detection of equipment output signals, wherein the equipment is connected to the aforementioned rapid equipment output signal testing device via an equipment cable. The equipment cable includes at least four branches: firing, locking, front position, and rear position. Each branch has an independent plug at one end to connect to the corresponding functional test socket on the equipment, and the other end is integrated into a common plug to connect to the first connection socket JCXS01 on the rapid equipment output signal testing device. The detection method includes:

[0025] Step 1: Connect the first connection socket JCXS01 of the equipment output signal rapid test device to the function test socket of the equipment via the equipment cable, and connect the second connection socket JCXS02 to the control device via the adapter cable.

[0027] Step 3: Drive the equipment to operate and measure the equipment output signal transmitted to the corresponding signal test port via the first connection socket JCXS01 using a measuring instrument.

[0028] Furthermore, since the equipment output signal is an ignition output signal, the step of connecting the measuring instrument to the selected signal test port includes: connecting the measuring instrument to the ignition output signal test port FH and the ignition ground signal test port FHGND to measure the ignition output signal;

[0029] The equipment output signal is a lockout output signal.

Additionally, the equipment's functional test sockets include at least an ignition socket, a latching socket, a front position socket, and a rear position socket.

[0037] When the equipment cable branch is not connected to the corresponding functional test socket on the equipment, the ignition cable detection signal, the interlocking cable detection signal, the front cable detection signal and the rear cable detection signal are all at low level, which are used to report the cable connection fault status to the host computer.

[0038] Once the equipment cable branch is reliably connected to the corresponding functional test socket on the equipment, the ignition cable detection signal, the locking cable detection signal, the front cable detection signal, and the rear cable detection signal are at a high level, which is used to report the normal cable connection status to the host computer.

[0039] The present invention also provides a method for detecting the connection status of equipment cables, comprising the following steps:

[0040] Step S1: Operate the cable test switch on the equipment output signal rapid test device corresponding to the equipment cable branch, and switch it from the closed state to the open state;

[0042] Step S2: Operate the cable test switch to restore it from the open state to the closed state;

[0043] Observe whether the connection status indicator corresponding to the equipment cable branch in the host computer interface has changed from a state indicating a connection failure to a state indicating a normal connection.

[0044] Step S3: If the results of steps S1 and S2 are both yes, it indicates that the equipment cable branch is connected normally; otherwise, it indicates that the equipment cable branch connection is faulty and needs to be repaired.

[0045] Furthermore, a green indicator light indicates a normal connection, while a red indicator light indicates a connection failure.

[0046] The advantages of this invention are:

[0047] 1. This invention, through the design of a rapid equipment output signal testing device, introduces the required equipment output signal into the corresponding signal test port of the testing device. Testers can use multimeters, oscilloscopes, and other equipment to measure all test ports under power to check whether the equipment output signal output status is normal. This achieves rapid and accurate testing of equipment output signals during equipment testing, avoiding the time-consuming and labor-intensive problem of traditionally using tooling cables to weld out test leads for equipment output signal testing, thus improving testing efficiency. Traditional testing using tooling cables takes about 20 minutes, while testing using the rapid equipment output signal testing device designed in this invention only takes 5 minutes, improving work efficiency by 75%.

[0048] 2. In the rapid testing device for equipment output signals designed in this invention, corresponding cable test switches are designed for the corresponding output signal test cables. After connecting the testing equipment to the control device via the equipment cable and adapter cable, the connection status of the ignition cable, interlocking cable, front cable, and rear cable can be quickly and safely detected by opening and closing the corresponding cable test switches and observing the corresponding cable status display on the host computer. This avoids the cumbersome operations of traditional methods, such as repeatedly switching the integrated power supply, plugging and unplugging the fixed connectors, and connecting the connectors. The traditional method for detecting cable connection status takes approximately 30 minutes, while the method of this invention is simple to operate and can complete all cable connection status detection work in just 10 minutes, improving work efficiency by 67%.

[0065] Figure 3 In this configuration, the n, p, Z, Y, X, a, w, v, u, t, W, V, A, B, C, b, c, D, d core wire interfaces of the first connector JCXS01 correspond to the n, p, Z, Y, X, a, w, v, u, t, W, V, A, B, C, b, c, D, d core wire interfaces of the second connector JCXS02. The wiring relationship is one-to-one and is used to transmit motor signals to the second connector JCXS02. There is no experimental testing requirement for the motor signal, and it does not affect the testing of the ignition signal, lockout signal, front position signal, and rear position signal.

[0066] The rapid testing method for ignition output signal, latching output signal, front position output signal, and rear position output signal using the testing device provided in this embodiment is as follows:

[0067] First, connect the first connection socket JCXS01 of the equipment output signal rapid test device to the functional test socket of the equipment via the equipment cable. Each independent plug of the equipment cable is reliably plugged into the ignition socket, interlock socket, front socket and rear socket on the equipment. Then, reliably connect the second connection socket JCXS02 to the control device via the adapter cable.

[0068] Then, connect the measuring instrument to the selected signal test port on the equipment output signal rapid test device. If it is necessary to test the ignition output signal, connect the measuring instrument to the ignition output signal test port FH and the ignition ground signal test port FHGND to measure the ignition output signal; if it is necessary to test the lockout output signal, connect the measuring instrument to the lockout output signal test port BS and the lockout ground signal test port BSGND to measure the lockout output signal; if it is necessary to test the previous position output signal, connect the measuring instrument to the previous position output signal test port YD1 and the previous position ground signal test port YD1GND to measure the previous position output signal; if it is necessary to test the subsequent position output signal, connect the measuring instrument to the subsequent position output signal test port YD2 and the subsequent position ground signal test port YD2GND to measure the subsequent position output signal.

[0069] The measuring instruments mentioned can be conventional measuring instruments such as multimeters and oscilloscopes. Furthermore, users can simultaneously measure the output signals of one or more devices according to their actual measurement needs.

[0070] Finally, after the connection is completed, the equipment is controlled by the host computer. The corresponding signal output by the equipment is transmitted to the corresponding signal test port through the first connection socket JCXS01 of the test device of this invention. The operator uses the connected measuring instrument to measure the corresponding equipment output signal.

[0071] To detect the connection status of the equipment cable DL1, this invention short-circuit the ignition cable detection power signal core wire interface FHC28V of the ignition socket with the ignition cable detection signal core wire interface FHC; short-circuit the locking cable detection power signal core wire interface BSC28V of the locking socket with the locking cable detection signal core wire interface BSC; short-circuit the front cable detection power signal core wire interface YD1C28V of the front socket with the front cable detection signal core wire interface YD1C; and short-circuit the rear cable detection power signal core wire interface YD2C28V of the rear socket. The YD2C interface of the rear cable detection signal core wire is shorted, so that: when the equipment cable branch is not connected to the corresponding functional test socket on the equipment, the ignition cable detection signal, the interlocking cable detection signal, the front cable detection signal, and the rear cable detection signal are all at a low level, used to report the cable connection fault status to the host computer; when the equipment cable branch is reliably connected to the corresponding functional test socket on the equipment, the ignition cable detection signal, the interlocking cable detection signal, the front cable detection signal, and the rear cable detection signal are at a high level, used to report the cable connection normal status to the host computer. The specific equipment cable connection status detection process is as follows:

[0072] First, switch the cable test switch SA1 on the equipment output signal rapid test device, which corresponds to the equipment cable ignition branch, from the closed state to the open state. Under normal communication conditions, check the host computer display interface and observe whether the connection status indicator corresponding to the equipment cable ignition branch changes from a state indicating normal connection (green) to a state indicating connection failure (red).

[0073] Next, restore the cable test switch SA from the open state to the closed state, and observe whether the connection status indicator corresponding to the equipment cable ignition branch in the host computer interface changes from the state indicating connection failure (red) to the state indicating normal connection (green).

[0074] If both observations are positive, it indicates that the equipment cable ignition branch is properly connected; otherwise, it indicates that the equipment cable ignition branch is faulty and requires repair.

[0075] Based on the above process, operate the interlocking cable test switch SA2, the preceding cable test switch SA3, and the following cable test switch SA4 to determine the connection status of the interlocking branch, the preceding branch, and the following branch of the equipment cable. The connection status of the four branches of the equipment cable can be detected simultaneously in parallel or sequentially. This cable testing method is simple to operate; by simply opening and closing the corresponding cable test switches, the connection status of the corresponding equipment cable branch can be intuitively determined through the status display on the host computer interface. This effectively solves the problem of traditional cable testing methods involving repeated plugging and unplugging of cables, which is time-consuming and labor-intensive.

[0076] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the scope of the technology disclosed in the present invention, and such modifications or substitutions should all be covered within the scope of protection of the present invention.
