Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] In existing technologies, the performance testing and factory testing of compressor bodies are usually carried out separately by two testing systems. However, this separate testing method has many inconveniences in actual operation, such as the need to frequently change the circuit, which increases the complexity and time cost of testing.

[0040] The original compressor body performance test and the factory batch production control cabinet test need to be separated, which is troublesome to modify the wiring; at the same time, the test monitor is next to the compressor, which is noisy during the test and poses a safety hazard.

[0041] Based on this, the present invention provides a hydrogen compressor testing system that selectively connects the high-frequency acquisition cabinet used for performance testing and the control cabinet used for factory testing via a multi-core cable plug. Simultaneously, the test data display screen is displayed remotely in the testing room via an HDMI remote transmission transceiver. Furthermore, the touchscreen of the mass-produced control cabinet is remotely monitored in the testing room via a network cable. This solves the problem of cumbersome replacement of the original testing system, improves testing efficiency, reduces testing costs, and ensures the safety of testing personnel.

[0042] To facilitate understanding of this embodiment, a detailed description of a hydrogen compressor testing system disclosed in this utility model embodiment will be provided first.

[0043] Example 1

[0044] This utility model provides a hydrogen compressor testing system. Figure 1 This is a structural diagram of a hydrogen compressor testing system provided in an embodiment of the present invention. Figure 1 As shown, the hydrogen compressor testing system may include the following structure: hydrogen compressor 110, high-frequency acquisition cabinet 120, control cabinet 130 and testing machine 140;

[0045] The hydrogen compressor 110 is equipped with a multi-core male plug, which is adapted to connect with the first multi-core female socket on the high-frequency acquisition cabinet 120. The hydrogen compressor 110 can be connected to the high-frequency acquisition cabinet 120, and the high-frequency acquisition cabinet 120 can perform high-frequency data acquisition from multiple sensors in the hydrogen compressor 110.

[0046] The hydrogen compressor 110 is connected to the second multi-pin female socket on the control cabinet 130 via the multi-pin male plug. The hydrogen compressor 110 can be connected to the control cabinet 130, and the control cabinet 130 can perform low-frequency data acquisition from multiple sensors in the hydrogen compressor 110.

[0047] The testing machine 140 is remotely connected to the high-frequency acquisition cabinet 120 and the control cabinet 130 respectively. The testing machine 140 can receive high-frequency data collected by the high-frequency acquisition cabinet 120 to perform performance testing on the hydrogen compressor 110 and obtain performance test results, and receive low-frequency data collected by the control cabinet 130 to perform factory testing on the hydrogen compressor 110 and obtain factory test results.

[0048] Furthermore, the hydrogen compressor 110 includes an analog sensor junction box 111, and the multi-pin male plug is disposed on the analog sensor junction box 111.

[0049] Furthermore, the hydrogen compressor 110 also includes a valve and alarm switch junction box 112 and a motor junction box 113; the valve and alarm switch junction box 112 is connected to the control cabinet 130, and the control cabinet 130 can control the valves in the valve and alarm switch junction box 112 and receive alarm signals fed back from the alarm switches connected to the alarm switch junction box; the motor junction box 113 is connected to the control cabinet 130, and the control cabinet 130 can control the opening and closing of the motor in the hydrogen compressor 110.

[0050] Specifically, the hydrogen compressor 110 includes an analog sensor junction box 111, a valve and alarm switch junction box 112, and a motor junction box 113. It can be understood that the hydrogen compressor 110 can be equipped with multiple analog sensors to acquire performance parameters such as temperature, gas pressure, and oil pressure of various components during operation. Each analog sensor in the hydrogen compressor 110 can be connected through the analog sensor junction box 111 to transmit the collected performance parameters. The analog sensor junction box 111 includes multiple connection ports, each corresponding to one analog sensor. A multi-pin male connector refers to a connector with multiple conductive pins. Each connection port in the analog sensor junction box 111 can be connected to one conductive pin of the multi-pin male connector, allowing one conductive pin to transmit the performance parameter collected by one analog sensor. The correspondence between conductive pins and analog sensors can be recorded in tabular form. Similarly, the hydrogen compressor 110 is equipped with multiple valves and at least one alarm switch. Each valve and alarm switch is connected to the control cabinet 130 via a valve and alarm switch junction box 112. In the junction box 112, each connection port corresponds to either a valve or an alarm switch. Understandably, when a connection port in the junction box 112 corresponds to a valve, the control cabinet 130 can control the opening and closing of the valve through the connection port; when a connection port corresponds to an alarm switch, the control cabinet 130 can receive alarm signals sent by the alarm switch through the connection port. For each valve, one valve can correspond to one alarm switch. The alarm signal sent by the alarm switch to the control cabinet 130 can indicate a malfunction in the valve corresponding to the alarm switch, allowing relevant personnel to handle the fault. The motor junction box 113 provides connection ports for the motor in the hydrogen compressor 110.

[0051] The first and second multi-pin female sockets are used for mating with multi-pin male plugs. Specifically, one pin in the first multi-pin female socket corresponds to one conductive pin in the multi-pin male plug, and vice versa. The first and second multi-pin female sockets cannot be mated with the multi-pin male plug simultaneously.

[0052] The test machine 140 can be set up in a remote test room, which is far away from the hydrogen compressor 110. This can reduce the impact of the hydrogen compressor 110 on the test personnel during the test and protect their safety.

[0053] The high-frequency data acquisition cabinet 120 uses the LANVIEW system to acquire high-frequency data from multiple sensors in the hydrogen compressor 110. High-frequency acquisition refers to short acquisition intervals; for example, for each sensor in the hydrogen compressor 110, high-frequency data could be acquired from 100 sensors within one second. The high-frequency data acquisition cabinet 120 is connected to the testing machine 140. The high-frequency data acquired by the cabinet 120 can be sent to the testing machine 140, where testing personnel can view the high-frequency data. The testing machine 140 can pre-set the abnormal range for the high-frequency data corresponding to each sensor. If at least one data point in the acquired high-frequency data meets the abnormal range, it indicates an abnormal high-frequency data, meaning the sensor's performance test result is abnormal. Testing personnel can then take appropriate measures to repair the hydrogen compressor 110 based on the abnormal high-frequency data. If all acquired high-frequency data does not meet the abnormal range, it indicates normal high-frequency data, meaning the sensor's performance test result is normal.

[0054] Control cabinet 130 uses a PLC system to perform low-frequency data acquisition from multiple sensors in hydrogen compressor 110. Low-frequency acquisition refers to long acquisition intervals; for example, for each sensor in hydrogen compressor 110, low-frequency data could be data from five sensors acquired within one second. Control cabinet 130 is connected to testing machine 140. The low-frequency data acquired by control cabinet 130 can be sent to testing machine 140, where testing personnel can view the low-frequency data. Testing machine 140 can also perform statistical analysis on the low-frequency data of each sensor, such as calculating the average value, to obtain the factory test results for each sensor.

[0055] Generally, high-frequency data is used by testers for internal testing of the hydrogen compressor 110 to ensure that its performance meets factory requirements. Low-frequency data is used by testers to demonstrate the performance of the hydrogen compressor 110, providing performance data to users and ensuring that its performance meets their needs.

[0056] This utility model provides a hydrogen compressor testing system that selectively connects the high-frequency acquisition cabinet used for performance testing and the control cabinet used for factory testing via a multi-core cable plug. Simultaneously, the test data display screen is displayed remotely in the testing room via an HDMI remote transmission transceiver. Furthermore, the touchscreen of the batch production control cabinet is remotely monitored from the testing room via a network cable. This system solves the problem of cumbersome replacement of existing testing systems, improves testing efficiency, reduces testing costs, and ensures the safety of testing personnel.

[0057] Example 2

[0058] This utility model embodiment also provides another hydrogen compressor testing system; this hydrogen compressor testing system is implemented based on the hydrogen compressor testing system of the above embodiment.

[0059] Figure 2 A structural diagram of another hydrogen compressor testing system provided in an embodiment of this utility model. (See diagram below.) Figure 2 As shown, the control cabinet 130 includes a PLC control cabinet 131 and a starter cabinet 132;

[0060] The PLC control cabinet 131 is connected to the valve and alarm switch junction box 112. The PLC control cabinet 131 can control the valve and receive alarm signals fed back by the alarm switch connected to the alarm switch junction box.

[0061] The starter cabinet 132 is connected to the motor junction box 113, and the starter cabinet 132 can control the start and stop of the motor in the hydrogen compressor 110;

[0062] The PLC control cabinet 131 is connected to the starter cabinet 132. The PLC control cabinet 131 can send control commands to the starter cabinet 132. The control commands are used to instruct the starter cabinet 132 to control the motor in the hydrogen compressor 110 to start and stop.

[0063] Furthermore, the high-frequency acquisition cabinet 120 includes an industrial control computer 121 and a transmitter 123;

[0064] The industrial control computer 121 is connected to the transmitter 123, and the industrial control computer 121 can send the collected high-frequency data to the test machine 140 through the transmitter 123;

[0065] The industrial control computer 121 is equipped with the first multi-core female socket, which is adapted to and connected to the multi-core male plug of the hydrogen compressor 110.

[0066] Furthermore, the industrial control computer 121 is equipped with a data acquisition board 122, which is used to acquire high-frequency data from multiple sensors in the hydrogen compressor 110. There is at least one data acquisition board 122. Specifically, the number can be determined based on the number of sensors in the hydrogen compressor 110. For example, one data acquisition board 122 can acquire high-frequency data from 42 sensors. When the number of sensors in the compressor is 68, two data acquisition boards 122 can be used; when the number of sensors in the compressor is 42, one data acquisition board 122 can be used. In this embodiment of the invention, the industrial control computer 121 can be an Advantech 610L industrial control computer, and the data acquisition board 122 can be an Advantech PCI 1713U high-frequency data acquisition card.

[0067] Furthermore, the test machine 140 includes a receiver 141, a display 142, and a touch screen 143;

[0068] The receiver 141 is connected to the transmitter 123, and the receiver 141 is capable of receiving high-frequency data sent by the transmitter 123;

[0069] The display 142 is connected to the receiver 141, and the display 142 is capable of displaying high-frequency data received by the receiver 141;

[0070] The touch screen 143 is connected to the PLC control cabinet 131. The touch screen 143 is used to send switch commands to the PLC control cabinet 131. The switch commands are used to instruct the PLC control cabinet 131 to control the opening and closing of the valve, and to instruct the PLC control cabinet 131 to control the starter cabinet 132 to start and stop the motor.

[0071] Furthermore, the testing machine 140 also includes an input device;

[0072] The input device is connected to the receiver 141. The input device is used to input attribute parameters of high-frequency data. The attribute parameters are used to perform performance analysis on the high-frequency data to obtain performance test results.

[0073] Furthermore, the industrial computer 121 is connected to the PLC control cabinet 131;

[0074] The input device is also used to input modification information of the PLC control program, which is used to modify the PLC control program in the PLC control cabinet 131 through the industrial computer 121.

[0075] Furthermore, the PLC control cabinet 131 has an automatic mode and a manual mode; the manual mode refers to the individual control of each valve and the motor in the valve and alarm switch group via the touch screen 143; the automatic mode refers to the one-button automatic start and stop operation of each valve and the motor in the valve and alarm switch group via the touch screen 143; when the multi-pin male plug of the hydrogen compressor 110 is connected to the first multi-pin female socket of the high-frequency acquisition cabinet 120, the PLC control cabinet 131 is controlled in manual mode; when the multi-pin male plug of the hydrogen compressor 110 is connected to the second multi-pin female socket of the control cabinet 130, the PLC control cabinet 131 is controlled in both manual and automatic modes respectively.

[0076] Specifically, during performance testing, the multi-pin male connector of the analog sensor junction box 111 of the hydrogen compressor 110 is connected to the PCI 1713U high-frequency acquisition card in the high-frequency acquisition cabinet 120. All analog operating parameters, i.e., the high-frequency data from each sensor, can be acquired and displayed at high frequency through the monitor 142 in the test room. When the control cabinet 130 is in manual mode, the touchscreen 143 debugging interface allows manual opening or closing of any one or more valves and alarm switches within the hydrogen compressor 110, as well as manual opening or closing of the motor. At this time, the touchscreen 143 sends switch commands to the PLC control cabinet 131, instructing it to control the opening and closing of the valves and to control the starter cabinet 132 to open and close the motor. It is understood that when the PLC control cabinet 131 controls the opening and closing of the valves, it can simultaneously control the opening and closing of the corresponding alarm switches. When an alarm switch is on, it can send an alarm signal to the PLC control cabinet 131 in case of a valve malfunction; conversely, it cannot send an alarm signal when the corresponding valve is off. The program in the PLC control cabinet 131 can be modified via the industrial computer 121. It is understood that the PLC control program can also be displayed on the monitor 142. Input devices can include a keyboard 144 and a mouse 145, through which modification information for the PLC control program can be input. This modification information refers to the content that needs to be modified in the PLC control program, such as parameters involved in the PLC control program. The modified PLC control program can be directly modified using this information, and then sent to the PLC control cabinet 131 via the industrial computer 121. When the hydrogen compressor 110 is running, the PLC control program in the PLC control cabinet 131 has been configured with relevant safety interlocks for shutdown. In the event of an abnormal operation, the abnormal signal can be transmitted to the PLC control cabinet 131 via OPC communication for an interlock shutdown, protecting equipment and personnel safety. The industrial computer 121 can determine whether the high-frequency data is normal by analyzing the attribute parameters of the high-frequency data input from the input device. If the high-frequency data meets the attribute parameters, it indicates that the high-frequency data is normal and the performance test result is normal. If the high-frequency data does not meet the attribute parameters, it indicates that the high-frequency data is abnormal and the performance test result is abnormal. In this case, the industrial computer 121 will issue an alarm signal, which will be transmitted from the transmitter 123 to the receiver 141 and displayed on the monitor 142. At the same time, the alarm signal will be sent to the PLC control cabinet 131, which will control the hydrogen compressor 110 to stop running, protecting the equipment and personnel safety. During performance testing, the PLC control cabinet 131 generally only uses manual mode to test the performance of valves, alarm switches, and motors one by one.

[0077] The attribute parameters of the high-frequency data are used to indicate whether the high-frequency data is normal. The attribute parameters are pre-set parameters stored in a table. The tester can use the keyboard 144 and mouse 145 to input the attribute parameters into the industrial control computer 121 according to the table and display them on the monitor 142. For example, if the collected high-frequency data is temperature data, the attribute parameter can be 50 degrees, indicating that the temperature data is abnormal when it is greater than 50 degrees and normal when it is less than or equal to 50 degrees. If the collected high-frequency data is air pressure data, the attribute parameter can be 1000Pa, indicating that the air pressure data is abnormal when it is greater than 1000Pa and normal when it is less than or equal to 1000Pa.

[0078] During factory testing, high-frequency data collection is not required. Therefore, the multi-pin male connector of the analog sensor junction box 111 inside the hydrogen compressor 110 is connected to the PLC control cabinet 131. The PLC control cabinet 131 then collects data from all analog sensors in the hydrogen compressor 110. Other connections remain unchanged. At this time, all data acquisition and control are performed by the PLC control cabinet 131 within the control cabinet 130. When the PLC control cabinet 131 is in manual mode, all valves and motors inside the hydrogen compressor 110 can be manually switched on and off via the touchscreen 143 debugging interface in the test room. During compressor operation, the PLC program within the PLC control cabinet 131 has been configured with relevant safety interlock shutdown mechanisms. In case of operational abnormalities, the system can promptly shut down, protecting equipment and personnel safety. When the PLC control cabinet 131 is in automatic mode, the hydrogen compressor 110 can be started and stopped with a single button via the main interface of the touch screen 143 in the test room. This means performing one-button automatic start and stop operations on the valves, alarm switches, and motors, simultaneously opening or closing all valves, alarm switches, and motors to verify the compressor's automatic start and stop function. During compressor operation, the PLC program within the PLC control cabinet 131 has pre-set safety interlock shutdown procedures. In case of malfunction, the system can promptly shut down the compressor to protect equipment and personnel safety. In this embodiment of the invention, the safety interlock shutdown is a pre-set shutdown program in the PLC program, used to shut down the motor, valves, and alarm switches when the hydrogen compressor 110 malfunctions.

[0079] This utility model provides a hydrogen compressor testing system that selectively connects the high-frequency acquisition cabinet used for performance testing and the control cabinet used for factory testing via a multi-core cable connector. Simultaneously, the test data display screen is displayed remotely in the testing room via an HDMI remote transmission transceiver. The touchscreen 143 of the batch production control cabinet is remotely monitored from the testing room via a network cable. This solves the problem of cumbersome replacement of existing testing systems, improves testing efficiency, reduces testing costs, and ensures the safety of testing personnel. The units described as separate components may or may not be physically separate. The components displayed as units may or may not be physical units; they may be located in one place or distributed across multiple network units.
