The device in the embodiments of the present application is provided with multiple detection interfaces, and the detection control system is integrated with multiple detection sub-modules corresponding to the detection interfaces, which can perform parameter full-coverage detection on the device, improve the detection efficiency and the fault detection accuracy.

[0042] Please refer to Figure 1 , Figure 1 which is the frame schematic diagram of the detection control system for the device provided by the embodiments of the present application.

[0043] The device includes multiple modules 110 to be tested and multiple detection interfaces 120. Among them, the device in the embodiments of the present application can be a device for controlling the movement of a controller such as a galvanometer control card, a laser welder, or a laser cutter.

[0044] In some embodiments, the detection control system of the device includes a detection module 200 and a control module 300. The following is a detailed description of these two modules.

[0045] The detection module 200 includes a digital processing module 210 and detection sub-modules 220 that correspond one-to-one with the detection interfaces 120. The detection sub-modules 220 are used to receive the detection signals corresponding to the detection interfaces 120. That is, the detection sub-modules 220 are connected to the modules under test 110 of the device through the detection interfaces 120, further realizing the detection of the working states of all the modules under test 110. The digital processing module 210 is connected to all the detection sub-modules 220 to preprocess the detection signals, convert the analog signals into digital signals, and be able to remove the noise and unnecessary signal components in the signals, obtaining multiple level signals, realizing the efficient processing of the signals, and improving the signal quality.

[0046] It should be noted that the digital processing module 210 in the embodiment of the present application is an FPGA (Field Programmable Gate Array) digital processing module 210. During the process of the digital processing module 210 preprocessing the detection signals, the FPGA first converts the external analog signals into digital signals, and then performs filtering processing on the converted detection signals to ensure that the signals will not generate phase distortion after filtering processing, so as to be able to reduce the noise and improve the signal quality. And the parallel processing ability of the FPGA enables it to process multiple signal streams simultaneously, greatly improving the speed and efficiency of signal processing.

[0047] The control module 300 is communicatively connected to the detection module 200. The control module 300 is used to receive all the level signals sent by the digital processing module 210. Among them, the level signals correspond to the modules under test 110, which is convenient for subsequently determining the working states of the modules under test 110 connected to the detection sub-modules 220 by analyzing the level signals, realizing the full-coverage detection of the modules under test 110 of the device, and then performing logical judgment on all the level signals to judge whether the functions of the device under test are normal, determining the target module under test 110 with abnormal signals in the logical judgment, and determining the target module under test 110 as a faulty module, realizing the accurate judgment of the faulty module, and avoiding the situation of insufficient coverage or fuzzy fault location.

[0048] It can be understood that the control module 300 in the embodiment of the present application includes an MCU (Micro Controller Unit) microprocessor 310.

[0049] It should be noted that after determining the target module under test 110 as a faulty module, the embodiment of the present application will also perform module positioning on the faulty module to determine the specific position of the module under test 110 with a fault in the device, realizing the accurate positioning of the faulty module, facilitating the subsequent maintenance by the staff, and reducing the maintenance cost.

[0050] In some embodiments, the detection and control system further includes a display module 400. The control module 300 includes a static storage interface, where the static storage interface is an FSMC (Flexible Static Memory Controller) interface. The display module 400 can be directly connected to the control module 300 through the static storage interface to display the logical judgment result. The entire process does not require an additional image processing chip, omits the intermediate driver chip in the traditional display module 400, and realizes the real-time display of the logical judgment result, improving the display stability.

[0051] It should be noted that the display module 400 in the embodiments of the present application includes a TFT LCD (Thin Film Transistor Liquid Crystal Display). The TFT LCD is directly connected to the control module 300 through the FSMC interface, and an independent backlight drive circuit is designed to ensure the display stability.

[0052] It can be understood that the existing control cards use segment displays or OLED (Organic Light-Emitting Diode) screens, which only support simple status indication. However, the embodiments of the present application achieve visualization through a high-resolution display and hardware direct connection detection, and do not require an additional image processing chip to reduce power consumption and cost.

[0053] In some embodiments, the module 110 to be tested includes a laser module, a galvanometer module, an I / O module, and an encoder module. Among them, the laser module is responsible for turning on and off the laser, ensuring that the laser beam is emitted according to a predetermined time and pattern. The galvanometer module is used to adjust the rotation angle of the galvanometer to adjust the position of the laser beam on the workbench. The I / O module is used to provide various input and output interfaces for communication with other devices. The encoder module is used to provide a feedback signal of the galvanometer position to achieve closed-loop control. The detection interface 120 includes a laser detection interface 120, a galvanometer detection interface 120, an I / O detection interface 120, and an encoder detection interface 120. The detection sub-module 220 includes a laser detection module 200, a galvanometer detection module 200, an I / O detection module 200, and an encoder detection module 200. The laser module is connected to the laser detection module 200 through the laser detection interface 120 to detect the working state of the laser module through the laser detection module 200. The galvanometer module is connected to the galvanometer detection module 200 through the galvanometer detection interface 120 to detect the working state of the galvanometer module through the galvanometer detection module 200. The I / O module is connected to the I / O detection module 200 through the I / O detection interface 120 to detect the working state of the I / O module through the I / O detection module 200. The encoder module is connected to the encoder detection module 200 through the encoder detection interface 120 to detect the working state of the encoder module through the encoder detection module 200, so as to achieve a comprehensive detection of each module 110 to be tested of the device.

[0054] Specifically, the module 110 to be tested further includes a power output module. The power output module is used to provide a stable power supply for the device to ensure that each module 110 to be tested in the device can work normally. The detection interface 120 further includes a power output interface. The detection sub-module 220 further includes a power detection module 200. The power output module is connected to the power detection module 200 through the detection interface 120 to detect the power supply of the device through the power detection module 200, ensuring that the device can operate stably and efficiently.

[0055] In some embodiments, the detection module 200 further includes a clock module 230. The clock module 230 is used to generate a clock signal. The clock module 230 is connected to the digital processing module 210 to distribute the clock signal. Through the clock module 230, the frequency and phase of the clock signal can be dynamically adjusted to ensure the stability and synchronization of the clock signal, so as to provide a stable working timing for the digital processing module 210.

[0056] It should be noted that the detection module 200 in the embodiments of the present application further includes a Flash module. The Flash module is used to store the configuration data and program code of the FPGA to achieve the storage of user data and avoid data loss after power off.

[0057] In some embodiments, the detection and control system further includes a power protection module 500. The power protection module 500 includes a first power protection sub-module 510 and a second power protection sub-module 520. The first power protection sub-module 510 is connected to the digital processing module 210 to provide a first power voltage, so as to be able to provide a stable voltage for the digital processing module 210, realize over-voltage protection and over-current protection for the digital processing module 210, and avoid damage caused by voltage fluctuations. The second power protection sub-module 520 is connected to the control module 300 to provide a second power voltage, realize over-voltage protection and over-current protection for the control module 300, and achieve protection for the control module 300.

[0058] In some embodiments, the detection interface 120 further includes a communication interface and a network interface. Among them, the communication interface can be an RS422 interface, an RS485 interface, a synchronous serial communication interface, etc., and the network interface can be an Ethernet interface, an optical fiber interface, etc. The embodiments of the present application do not make specific limitations.

[0059] The device is connected to the control module 300 through the communication interface for communication, so as to be able to effectively resist interference signals from the outside world, realize long-distance transmission between the device and the control module 300, and improve data transmission efficiency. And the device is connected to the control module 300 through the network interface for data transmission, so as to realize high-speed data transmission between devices.

[0060] It should be noted that taking the device as a galvanometer control card as an example, the galvanometer control card in the embodiments of the present application integrates an RS422 interface and an Ethernet interface, can automatically identify the host computer communication protocol and switch to the corresponding channel, and realize data interaction with the host computer.

[0061] It can be understood that traditional control cards rely more on a single interface, and there are problems of low speed and poor compatibility. However, the galvanometer control card in the embodiments of the present application supports multi-threaded data interaction through a dual physical channel and protocol adaptive design.

[0062] In some embodiments, the control module 300 further includes an MCU clock module 320 and a reset module 330. Among them, the MCU clock module 320 is used to provide timing signals for the processor in the control module 300, ensure that each logic unit and module in the processor can run synchronously, so as to provide a stable clock signal to ensure the stability and reliability of the clock signal. The reset module 330 is used to initialize the processor to a known initial state to ensure that the processor can operate normally when starting up or when an error occurs.

[0063] Please refer to Figure 2 , Figure 2 is a flowchart of the specific method of the detection and control method of the device provided by an embodiment of the present application. Apply but not limited to the aboveFigure 1 The control module 300 in the detection and control system of the device shown. In some embodiments, the detection and control method of the device includes but is not limited to steps S101 to S103.

[0064] Step S101: Receive all the level signals sent by the digital processing module 210, where the level signals correspond to the module under test 110.

[0065] Step S102: Perform a logical judgment on all the level signals to obtain a logical judgment result.

[0066] Step S103: Determine the target module under test 110 for which the logical judgment is an abnormal signal according to the logical judgment result, and determine the target module under test 110 as a faulty module.

[0067] In steps S101 to S103 of some embodiments, in the embodiments of the present application, all the level signals sent by the digital processing module 210 are received first, where the level signals correspond to the module under test 110, which is convenient for subsequently judging the working state of the module under test 110 through the level signals. After receiving all the level signals, a logical judgment is performed on all the level signals. Specifically, it is judged whether the module under test 110 is normal by detecting the presence, absence, high or low of the level input to each module under test 110, so as to determine the target module under test 110 with an abnormal signal in the logical judgment, and determine the target module under test 110 as a faulty module, ensuring comprehensive coverage detection of the device, realizing accurate judgment of abnormal signals, and facilitating subsequent positioning of the faulty module.

[0068] It can be understood that in the embodiments of the present application, by detecting the high, low, presence or absence of the level, it is possible to quickly judge whether there is a fault in the I / O interface, and the device and system in the embodiments of the present application can quickly complete the detection of a large number of I / Os by integrating multiple interfaces, improving the detection efficiency and reducing the time for troubleshooting problems.

[0069] In some embodiments, after determining the target module under test 110 as a faulty module, the control module 300 also sends the logical judgment result to the display module 400 for display through the display module 400, realizing visual display of the entire process of logical judgment.

[0070] Please refer to Figure 3 , Figure 3 is a flowchart of a specific method for performing a logical judgment on all level signals provided in an embodiment of the present application. The method includes but is not limited to steps S201 to S206.

[0071] It should be noted that the detection and control system further includes a data storage module, and the data storage module stores the preset level signals for each module under test 110.

[0072] Step S201: For each target module to be tested 110, determine whether there is a target level signal corresponding to the target module to be tested 110 in the level signal.

[0073] Step S202: When there is a target level signal corresponding to the target module to be tested 110 in the level signal, determine the target preset level signal corresponding to the target level signal in the data storage module.

[0074] Step S203: Compare the target level signal with the target preset level signal.

[0075] Step S204: When the target level signal is inconsistent with the target preset level signal, determine the target level signal as an abnormal signal.

[0076] Step S205: When the target level signal is consistent with the target preset level signal, determine the target level signal as a normal signal.

[0077] Step S206: Obtain a logical judgment result according to the signal judgment result of each target module to be tested 110.

[0078] In steps S201 to S206 of some embodiments, for each target module to be tested 110, this application embodiment will determine whether there is a target level signal corresponding to the target module to be tested 110 in the level signal. When there is a target level signal corresponding to the target module to be tested 110 in the level signal, it indicates that the control module 300 has received the target level signal corresponding to the target module to be tested 110, that is, the target module to be tested 110 has a level input. At this time, determine the target preset level signal corresponding to the target level signal in the data storage module, and then compare the target level signal with the target preset level signal to determine whether the target level signal is consistent with the preset level signal. When the target level signal is inconsistent with the target preset level signal, it indicates that the target level signal does not match the expectation, then determine the target level signal as an abnormal signal to achieve accurate judgment of the abnormal signal and facilitate subsequent positioning of the faulty module. When the target level signal is consistent with the target preset level signal, it indicates that the target level signal is consistent with the expectation, and the target level signal can be directly determined as a normal signal. Finally, according to the signal judgment result of each target module to be tested 110, that is, according to whether the signal corresponding to each target module to be tested 110 is an abnormal signal or a normal signal, generate a logical judgment result to achieve the collection of normal signals and abnormal signals and facilitate subsequent positioning of the faulty module.

[0079] Please refer to Figure 4 , Figure 4 which is the flowchart of the detection control method provided by another embodiment of this application. The method includes but is not limited to step S301.

[0080] It should be noted that step S301 occurs after determining whether there is a target level signal corresponding to the target DUT 110 in the level signals.

[0081] Step S301: When there is no target level signal corresponding to the target DUT 110 in all the level signals, the target DUT 110 is determined as the target DUT 110.

[0082] In step S301 of some embodiments, after determining whether there is a target level signal corresponding to the target DUT 110 in the level signals, when there is no target level signal corresponding to the target DUT 110 in all the level signals, it indicates that the control module 300 has not received the level signal sent by the target DUT 110, that is, the target DUT 110 has no level input. At this time, the target DUT 110 is directly determined as the target DUT 110.

[0083] It should be noted that in the process of logically judging all the level signals in the embodiments of the present application, it is determined whether the DUT 110 is normal by detecting the presence, absence, high level, and low level of the levels input by each DUT 110. Specifically, the control module 300 first detects whether each DUT 110 has a level input, and determines the DUT 110 without level input as a faulty module. For the DUT 110 with level input, it is detected whether the level signal corresponding to the DUT 110 is consistent with the preset level signal. If the detected level signal is consistent with the preset level signal, for example, after setting a high level, a high level is detected; after setting a low level, a low level is detected, then it is determined that the working state of the DUT 110 is normal. If the detected level signal does not match the preset level signal, for example, after setting a high level, a low level is detected, then it is determined that the working state of the DUT 110 is abnormal, so that all the DUTs 110 of the testing device can be tested synchronously, ensuring a comprehensive coverage detection of the device.
