[0002] With the upgrading of industrial automation and the advancement of intelligent manufacturing systems, equipment status perception has become a core link in ensuring production continuity and operational safety. As a fundamental component for sensing the operating status of equipment, the performance stability of start / stop sensors directly determines the reliability of industrial equipment status monitoring networks. In large-scale industrial scenarios, whether it's the quality verification of newly manufactured sensors or the periodic performance calibration of in-service sensors, professional testing methods are required to verify their signal output accuracy and operational condition adaptability. This requirement has become a key component of quality control in the industrial sensing layer.

[0003] Currently, there are still obvious industry-specific limitations in the testing solutions for start-stop sensors in the industrial field: on the one hand, traditional testing methods rely on a combination of distributed equipment and lack a unified integrated carrier, which not only increases the deployment complexity of on-site testing, but also easily leads to testing errors due to insufficient coordination between modules, making it difficult to meet the needs of efficient and standardized testing in industrial scenarios.

[0037] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0038] The start-stop test fixture of this utility model embodiment will be described below with reference to the accompanying drawings.

[0039] like Figures 1-5 As shown, the start-stop test fixture of this utility model embodiment includes an equipment frame 1, an electrical measurement module, an adjustment module, and a sensing module;

[0040] The electrical measurement module and the adjustment module are both fixedly mounted on the equipment frame 1, and the sensing module, the adjustment module, and the electrical measurement module form a closed detection loop;

[0041] The electrical measurement module includes ammeter 4 and voltmeter 5;

[0042] The adjustment module includes an adjustable resistor 13, a voltage converter 14, and a working cable 3. The working cable 3 is mounted on the equipment frame 1 and is connected to the adjustable resistor 13 and the voltage converter 14.

[0043] The sensing module includes an on / off sensor 8, a sensor output device, and a detection module.

[0044] Specifically, when the tooling is working, the adjustment module first sets up an adaptation to the test conditions: the adjustable resistor 13 adjusts the circuit resistance, the voltage converter 14 adapts the working voltage, and the two form a stable test environment through the working cable 3.

[0045] Subsequently, the sensing module starts detection: the start / stop sensor 8 senses the start / stop related signals of the target device, and the sensor output device transmits the signals to the detection module for processing;

[0046] Simultaneously, the electrical measurement module works in sync: ammeter 4 collects the current of the detection loop in real time, and voltmeter 5 monitors the voltage of the loop to help judge the stability of the operating conditions.

[0047] The entire process relies on a closed detection loop formed by the sensing module, the regulation module, and the electrical measurement module to complete the testing and signal processing of the equipment's start-up and shutdown status.

[0048] In one embodiment of this utility model, the detection module includes a signal shaping module, a motherboard chip, and a sensor output device;

[0049] The output terminal of the start / stop sensor 8 is electrically connected to the signal shaping module;

[0050] The signal shaping module is used to amplify and shape the leakage magnetic signal. The output of the signal shaping module 802 is connected to the motherboard chip.

[0051] The motherboard chip is used for logical judgment and outputs switch signals, and the signal output terminal is connected to the detection circuit.

[0052] When the start-stop test fixture is working, the start-stop sensor 8 first collects the leakage magnetic signal of the target device. After the signal is transmitted to the detection module, it is first processed by the signal shaping module. In view of the possible weakness and interference of the original leakage magnetic signal, the signal shaping module amplifies and enhances the signal strength, and at the same time optimizes the signal waveform by shaping to ensure that the signal meets the requirements of subsequent processing.

[0053] The processed signal is transmitted to the motherboard chip, which performs logical analysis and judgment on the signal to identify the start / stop status of the target device, and then generates and outputs the corresponding switch signal. Finally, the switch signal output by the motherboard chip is branched into the detection circuit, providing the core basis for judging the start / stop status of the device for the entire tooling detection process, and assisting in completing the test of the device's start / stop performance.

[0054] In one embodiment of the present invention, the sensor output device is a wireless device, and the signal input terminal of the wireless device is electrically connected to the signal output terminal of the start / stop sensor 8 to receive the detection signal output by the start / stop sensor 8.

[0055] The detection module includes a wireless receiver module for receiving signals from wireless devices.

[0056] Specifically, during the tooling inspection process, the sensor output device participates in signal transmission in the form of a wireless device: after the start / stop sensor 8 generates a detection signal, the wireless device directly acquires the signal and then transmits the signal wirelessly to the outside, realizing non-contact transmission of the detection signal.

[0057] Meanwhile, the wireless receiving module in the detection module is also in the signal receiving state. When it receives the signal sent by the wireless device, it will transmit the signal to the main board chip of the detection module. The main board chip combines the magnetic flux leakage signal processed by the signal shaping module previously, further completes logical judgment, and finally outputs the corresponding digital signal to the detection circuit to ensure the complete detection process of the tooling for the start / stop state of the equipment.

[0058] In an embodiment of the present utility model, the sensor output device includes a sensor adapter joint 9, a connecting wire 10, and a connecting end 11. The detection module includes a connection port 12, and the connection port 12 is arranged on the panel of the equipment rack 1. The sensor adapter joint 9 is adapted to the signal output joint of the start / stop sensor 8. The sensor adapter joint 9 is connected to the connecting end 11 through the connecting wire 10, and the connecting end 11 can be connected to the connection port 12.

[0059] When the start / stop sensor 8 outputs a signal, the signal is first led out through the sensor adapter joint 9, which is adapted to the signal output joint of the start / stop sensor 8.

[0060] Subsequently, the connecting wire 10 receives the signal led out by the sensor adapter joint 9 and transmits the signal stably to the connecting end 11. The connecting end 11 is docked with the connection port 12 on the panel of the equipment rack 1 by means of plugging and unplugging, completing the transfer of the signal from the sensor output device to the detection module.

[0061] In an embodiment of the present utility model, the ammeter 4 and the voltmeter 5 are arranged on the panel rack of the equipment rack 1.

[0062] Specifically, when the tooling starts and enters the detection state, the current and voltage signals in the detection circuit will be synchronously fed back to these two instruments: the ammeter 4 displays the change of the circuit current in real time, helping the operator judge whether the current circuit load is stable and whether it matches the working current requirement of the start / stop sensor 8; the voltmeter 5 synchronously presents the circuit voltage value to assist in confirming whether the voltage is within the adaptation range for the normal operation of the sensor.

[0063] In an embodiment of the present utility model, it further includes a plurality of cable fixing brackets 2 for fixing the working cable 3;

[0064] The plurality of cable fixing brackets 2 are arranged at intervals along the length direction of the detection table of the equipment rack 1. Each cable fixing bracket 2 includes a fixing column 201, a bolt column 202, a compression frame 203, and a fixing nut 204;

[0065] The fixing column 201 is vertically and fixedly connected to the tabletop of the detection table of the equipment rack 1. The compression frame 203 is of a "U" - shaped structure. The bolt column 202 penetrates through the top cross beam of the compression frame 203 in the vertical direction, and the lower end of the bolt column 202 is threadedly connected to the top end of the fixing column 201;

[0066] The fixing nut 204 is fitted onto the upper end of the bolt 202, and the lower surface of the fixing nut 204 abuts against the top crossbeam of the compression frame 203.

[0067] Specifically, before the tooling is put into operation, the working cable 3 is laid along the length of the testing table of the equipment frame 1 and inserted into the "U"-shaped compression frame 203 of the cable fixing frame 2 at intervals. Then, the bolt 202 is rotated, and with the help of its threaded engagement with the fixing column 201, the compression frame 203 is moved downward in the vertical direction until the inner wall of the compression frame 203 and the testing table surface clamp the working cable 3 together. Finally, the fixing nut 204 fitted on the upper end of the bolt 201 is tightened, and the clamping position of the compression frame 203 is locked by the contact between the lower surface of the fixing nut 204 and the top crossbeam of the compression frame 203.

[0068] In one embodiment of the present invention, a cable end 16 is provided at the end of the working cable 3, and the cable end 16 is equipped with a cable connector 15 adapted thereto.

[0069] Specifically, when the tooling is used to set up the detection circuit, the cable connector 15 that is compatible with the cable end 16 is connected to it, so that the working cable 3 can be connected to the corresponding connection position of the tooling through the cooperation of these two components.

[0070] In one embodiment of this utility model, the connection terminal of the adjustable resistor 13 is integrated into the mounting panel of the equipment frame 1, and the adjustment knob of the adjustable resistor 13 is exposed on the mounting panel. Specifically, rotating the knob changes the resistance value of the adjustable resistor 13, thereby adjusting the resistance parameters of the detection circuit in real time to adapt to the requirements of the circuit load under different test scenarios and ensure that the test conditions are consistent with the actual needs.

[0071] In one embodiment of this utility model, it further includes a resistance regulating box 6 and a voltage regulating box 7. The openings of the resistance regulating box 6 and the voltage regulating box 7 are both hinged with doors. An adjustable resistor 13 is disposed inside the resistance regulating box 6, and a voltage converter 14 is disposed inside the voltage regulating box 7.

[0072] Specifically, during the test, the adjustable resistor 13 in the resistance regulating box 6 maintains the corresponding resistance value according to the previous setting, providing a stable resistance environment for the detection circuit; the voltage converter 14 in the voltage regulating box 7 runs continuously, converting the input voltage into a voltage value that meets the detection standard, ensuring stable power supply to the circuit.

[0073] In actual use,

[0074] After preparation, the appropriate testing conditions are set up by adjusting the module: the operator adjusts its resistance value to set the appropriate load for the testing circuit; at the same time, the voltage converter 14 in the voltage regulating box 7 is started to convert the input voltage into a voltage value that meets the testing standard; the working cable 3 connects the resistance parameter of the adjustable resistor 13 with the appropriate voltage of the voltage converter 14 to form the test conditions in the fixture.

[0075] Sensing and detection initiate signal acquisition and transmission. Once the operating conditions stabilize, the sensing module initiates detection, starting and stopping sensor 8 to acquire the leakage magnetic signal from the target device. The signal can then be transmitted in two ways:

[0076] Wireless transmission: The wireless device in the sensor output device directly acquires the leakage magnetic signal and transmits it wirelessly; the wireless receiving module of the detection module synchronously receives the signal and transmits it to the main board chip of the detection module.

[0077] Wired connection: The sensor adapter 9 of the sensor output device is adapted to the signal output connector of the start / stop sensor 8. After the signal is led out, it is transmitted to the connection terminal 11 via the connection cable 10. The connection terminal 11 is connected to the connection port 12 on the panel of the equipment frame 1 to complete the transfer of the signal to the detection module.

[0078] Signal processing generates a judgment signal. After receiving the signal, the detection module performs step-by-step processing: First, the signal shaping module amplifies and enhances the weak signal and shapes and optimizes the interference waveform of the original leakage magnetic signal. The processed signal is then transmitted to the motherboard chip. The motherboard chip performs logical analysis on the signal, identifies the start / stop status of the target device, generates and outputs the corresponding switch signal, and this signal is branched into the detection circuit to provide the core judgment basis for testing.

[0079] In summary, the start-stop test fixture of this utility model integrates three major modules—electrical measurement, adjustment, and sensing—to form a closed-loop detection system. The adjustment module can adjust the loop parameters through adjustable resistors and voltage converters to adapt to the testing requirements of different equipment.
