[0045] Embodiment 1:

[0046] Reference Figure 1 In an embodiment of the present invention, the driver detection system includes a host computer, a signal controller and a signal adapter board; wherein the host computer is connected to the signal controller and the driver to be tested respectively, the signal controller is connected to the signal adapter board, and the signal adapter board is connected to the driver to be tested. In an embodiment of the present invention, the driver detection system provides three detection paths for detecting the driver to be tested, specifically including:

[0047] 1. The host computer sends a detection command to the signal controller. The signal controller sends the detection command to the corresponding input port of the driver to be tested through the signal adapter board according to the detection command. After the input port of the driver to be tested receives the detection command, it responds to the detection command to obtain a response result, and the driver to be tested sends the response result to the host computer to complete the detection process.

[0048] 2. The host computer sends a detection command to the driver under test. The driver under test responds to the detection command and obtains a response result. The driver sends the response result to the corresponding input of the signal controller through the signal adapter board. The signal controller feeds back the response result to the host computer to complete the detection process.

[0049] 3. The host computer sends a detection command to the driver under test. After the driver under test responds to the detection command and obtains a response result, the driver under test directly feeds back the response result to the host computer.

[0050] In the embodiment of the present invention, the driver detection system is provided with the above-mentioned three driver detection paths, providing a transmission path for the host computer to issue different detection instructions with corresponding detection instructions, and a feedback path for the driver to be tested to respond to the detection instruction and obtain a response result. Since the hardware performance detection of the driver usually includes multiple parameter detections of hardware performance, the manual detection method inevitably has the problems of low efficiency and high error rate. In the driver detection system of the embodiment of the present invention, the host computer directly sends the detection instruction to the driver to be tested or forwards it to the driver to be tested by the signal controller and the signal adapter board. After the driver to be tested responds to the detection instruction and obtains a response result, it is fed back to the host computer by the driver to be tested or by the signal controller and the signal adapter board, which solves the technical problems of low driver detection efficiency and high error rate in the prior art, and provides an efficient and accurate driver detection system.

[0051] Embodiment 2:

[0052] Reference Figure 2 In an embodiment of the present invention, the driver detection system further includes a signal conversion socket, the output end of the signal adapter board is connected to the input end of the signal conversion socket, and the output end of the signal conversion socket is connected to the input end of the signal controller. In this embodiment, the signal conversion socket is used to convert the differential pulse signal output by the signal adapter board (the differential pulse signal output by the driver to be tested to the signal conversion socket) into a common-pole pulse signal, and transmit the common-pole pulse signal to the signal controller.

[0053] In the embodiment of the present invention, if the detection instruction sent by the host computer is a detection instruction for the output of a differential pulse signal by the driver to be tested, the host computer directly sends a differential pulse signal detection instruction to the driver to be tested, and the driver to be tested responds to the received differential pulse signal detection instruction and outputs a differential pulse signal (response result), and the differential pulse signal is transmitted to the signal conversion socket via the signal adapter board, and the signal conversion socket converts the differential pulse signal into a common-pole pulse signal and outputs it to the signal controller, and the signal controller feeds the received common-pole pulse signal back to the host computer. The embodiment of the present invention realizes the detection of the function of the driver outputting a differential pulse signal by providing a signal conversion socket. In this embodiment, after the driver to be tested outputs a differential pulse signal in response to the differential pulse signal detection instruction, it sends a response action completion message to the host computer, and at this time, the host computer monitors the corresponding input points of the signal controller to complete the detection of the function of the driver to be tested outputting a differential pulse signal. Since the output differential pulse signal may be a function jointly realized by multiple hardware in the driver to be tested, the detection of these hardware is completed by detecting the performance of the driver to be tested outputting a differential pulse signal.

[0054] Embodiment three:

[0055] Reference Figure 3In the embodiment of the present invention, the host computer includes an HMI (human-machine interface), the signal controller includes a PLC, and the signal adapter board includes an IO adapter board. In the present embodiment, the HMI is a touch screen interface, and the detection instructions of each driver to be tested can be issued by the HMI, and data information is transmitted between the HMI and the driver to be tested through the modbus communication protocol, and data information is transmitted between the HMI and the PLC through the RS232 serial port communication protocol. In the present embodiment, after the HMI receives the response result (the response result can be directly transmitted to the HMI by the driver to be tested, or indirectly through the IO adapter board and the PLC, and then fed back to the HMI by the PLC), the response result is compared with the preset reference value, and it is obtained whether the hardware of the driver to be tested detected by the detection instruction has a fault, and the detection result is displayed. For example, if there is a fault, the detection item corresponding to the detection instruction is displayed in red, otherwise it is displayed in green. In addition, the HMI can collect and save the detection results, and save the detection results in the fault record database. The data information in the fault record database can be used as reference data for the development and detection of the driver, which is conducive to improving the performance of the driver.

[0056] In some embodiments, the signal controller also includes an analog output expansion module, one end of the analog output expansion module is connected to the PLC, and the other end is connected to the IO adapter board. The analog output expansion module can expand the number of IO ports of the PLC, thereby improving the detection efficiency of the driver detection system in this embodiment.

[0057] In combination with the above three embodiments, the working process principle of the driver detection system is explained below through the hardware detection of a specific driver to be tested:

[0058] 1. The IO output port detection command is used to detect the IO output port of the drive to be tested:

[0059] Reference Figure 4 , the HMI touch screen sends the IO output port detection instruction to the driver under test through the modbus communication protocol. After receiving the IO output port detection instruction, the driver under test outputs a signal "1" (response action) to the IO output port of the driver under test, indicating that the IO output port of the driver under test has a signal output. The IO output port of the driver under test is connected to the input point of the PLC through the IO adapter board. When the driver under test completes the response action of the IO output port detection instruction, it sends a response action completion message to the HMI. The HMI touch screen detects the corresponding input point of the PLC. If the signal of the corresponding input point changes from "0" to "1", it indicates that the corresponding IO output port of the driver under test is normal. If the signal of the corresponding input point is always "0", it indicates that the IO output port of the driver under test is damaged.

[0060] 2. The IO input port detection command is used to detect the IO input port of the drive to be tested:

[0061] Reference Figure 5 , the HMI touch screen sends the IO input port detection command to the PLC through the RS232 serial port communication protocol. After receiving the IO input port detection command, the PLC sends a signal "1" to the corresponding input port of the drive to be tested through the IO adapter board. At this time, the HMI touch screen obtains the data information of the corresponding input port of the drive to be tested through the modbus communication protocol. If the signal of the corresponding IO input port of the drive to be tested changes from "0" to "1" (response action), it indicates that the corresponding IO input port of the drive to be tested is normal. If the signal of the corresponding IO input port of the drive to be tested is always "0", it indicates that the IO input port of the drive to be tested is damaged.

[0062] 3. The driver differential pulse signal detection instruction is used to detect the differential pulse signal output of the driver to be tested:

[0063] Reference Figure 6 , the HMI touch screen sends the differential pulse signal detection instruction to the driver under test through the modbus communication protocol. After the driver under test receives the differential pulse signal detection instruction, the driver under test outputs the differential pulse signal to the IO adapter board (response action). The differential pulse signal output by the IO adapter board is converted into a common-pole pulse signal by the signal conversion socket and then transmitted to the corresponding input point of the PLC. When the driver under test completes the response action of the differential pulse signal detection instruction, it sends a completion message of the response action to the HMI. The HMI touch screen detects the corresponding input point of the PLC. If the common-pole pulse signal of the corresponding input point of the PLC detected by the HMI meets the preset reference value, it indicates that the differential pulse signal output of the driver under test is normal (the relevant hardware of the driver output pulse signal is normal), otherwise it indicates that the relevant hardware of the output pulse signal of the driver under test is faulty.

[0064] 4. The fourth type of detection instructions:

[0065] The fourth category of detection instructions does not include any of the IO output port detection instructions, IO input port detection instructions, and differential pulse signal detection instructions.

[0066] Reference Figure 7 The HMI touch screen sends the fourth type of detection instruction to the driver under test through the modbus communication protocol. After receiving the fourth type of detection instruction, the driver under test responds to the fourth type of detection instruction to obtain a response result. The driver under test feeds back the response result to the HMI touch screen through the modbus communication protocol. The HMI touch screen determines whether the response result meets the preset reference value and completes the detection process.

[0067] For example, for the detection of the driver bus voltage, the HMI touch screen sends the driver bus voltage detection instruction to the driver under test through the modbus communication protocol. After the driver under test receives the driver bus voltage detection instruction, the driver under test runs (response action) and feeds back the driver bus voltage to the HMI touch screen through the modbus communication protocol. The HMI touch screen determines whether the received driver bus voltage meets the preset reference value and obtains the detection result.

[0068] In some embodiments, it is apparent that the encoder status, regeneration resistance, etc. of the driver to be tested can be detected by the above-mentioned driver detection system.

[0069] In summary, a driver detection system in an embodiment of the present invention is provided with a host computer respectively connected to a signal controller and a driver to be tested, and the signal controller is connected to a signal adapter board and then connected to the driver to be tested; when performing detection, a detection instruction is directly sent to the driver to be tested by the host computer or forwarded to the driver to be tested by the signal controller and the signal adapter board. After the driver to be tested responds to the detection instruction and obtains a response result, the response result is fed back to the host computer by the driver to be tested or by the signal controller and the signal adapter board, thereby solving the technical problems of low driver detection efficiency and high error rate in the prior art, and providing an efficient and accurate driver detection system.

[0073] S200, the driver to be tested responds to the detection instruction to obtain a response result;

[0077] In some embodiments, if the detection instruction is an IO input port detection instruction of the driver to be tested,

[0078] The host computer sends a detection instruction to the signal controller, and the signal controller sends the detection instruction to the corresponding input port of the driver to be tested through the signal adapter board according to the detection instruction; the driver to be tested responds to the detection instruction to obtain a response result, and feeds the response result back to the host computer.

[0079] In some embodiments, if the detection instruction is a differential pulse signal detection instruction,

[0080] The driver under test directly receives the differential pulse signal detection instruction from the host computer, and the driver under test responds to the differential pulse signal detection instruction to obtain a response result, and transmits the response result to the signal conversion socket through the signal adapter board for signal conversion, and then sends the response result after signal conversion to the corresponding input port of the signal controller, and the signal controller feeds back the response result to the host computer.

[0081] In some embodiments, if the detection instruction is a fourth type of detection instruction, wherein the fourth type of detection instruction does not include any one of an IO output port detection instruction, an IO input port detection instruction, and a differential pulse signal detection instruction;
