Description

Technical Field

[0001] This application relates to the field of sensor detection technology, and in particular to a detection system and vehicle using a Hall effect sensor. Background Technology

[0002] In automotive window motor control systems, Hall effect sensors are used to detect motor speed and position, and are key components for enabling window raising and lowering and anti-pinch functions. To ensure their reliability, Hall effect modules must undergo rigorous testing during the manufacturing process.

[0003] In related technologies, commonly used static parameter testing methods typically require installing the Hall module under test into the actual motor cavity and connecting a dedicated wiring harness for power supply and signal acquisition. After testing, the module must be disassembled and the wiring harness disconnected, making the process cumbersome and time-consuming, which is difficult to meet the needs of efficient mass production. Furthermore, existing testing methods mostly rely on oscilloscopes to observe the output waveform, only able to determine the presence and basic quality of the waveform, but unable to accurately count Hall pulse signals, thus making it difficult to effectively identify critical faults such as signal loss or pulse absence. Simultaneously, the entire testing process lacks automatic triggering, intelligent judgment, and abnormal alarm mechanisms, and also lacks monitoring of external factors such as power supply voltage fluctuations, making the test results susceptible to human factors and environmental interference, resulting in insufficient overall testing accuracy and consistency. Therefore, there is an urgent need for a testing system with a reasonable structure, simple operation, high degree of automation, and the ability to accurately determine the integrity of Hall signals to improve the factory quality and testing efficiency of Hall modules.

Examples of the embodiments 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 this application, and should not be construed as limiting this application.

[0020] The detection system and vehicle of the Hall module sensor according to embodiments of this application are described below with reference to the accompanying drawings.

[0021] Specifically, Figure 1 This is a block diagram of the detection system of the Hall module sensor according to an embodiment of this application.

[0022] like Figure 1 As shown, the detection system 10 of the Hall module sensor includes: device body 100, test module 200, magnetic field simulation module 300, sensing module 400 and control module 500.

[0023] The test module 200, magnetic field simulation module 300, sensing module 400, and control module 500 are disposed within the device body 100. The test module 200 is used to detachably accommodate the Hall module to be tested, power the Hall module, and collect the Hall pulse signals generated by the Hall module. The magnetic field simulation module 300 is used to provide a rotating magnetic field to the Hall sensor in the Hall module when the Hall module is placed in the test module. The sensing module 400 is disposed at the target position of the test module and is used to generate a corresponding trigger signal when the Hall module is placed in position. The control module 500 is electrically connected to the test module 200, magnetic field simulation module 300, and sensing module 400. It is used to respond to the trigger signal of the sensing module 400, control the operation of the magnetic field simulation module 300 to provide a rotating magnetic field signal, and use the test module 200 to collect the Hall pulse signals generated by the Hall module, count the number of Hall pulse signals to generate a counting result, and generate a detection conclusion based on the counting result and a preset pulse count range.

[0024] The main body of the equipment is the main housing 10.

[0025] The preset number of pulses can be set according to actual needs, without any specific limitation.

[0026] It is understood that the embodiments of this application can achieve rapid clamping and automatic testing of Hall modules by integrating the test module, magnetic field simulation module, sensing module and control module into the device body, without the need to assemble it into the motor cavity or connect it to an external wiring harness; when the Hall module is placed into the test module and in place, the sensing module immediately triggers the control module to start the magnetic field simulation module, generating a rotating magnetic field to excite the Hall sensor to output pulse signals. The control module synchronously collects and accurately counts the number of Hall pulses, and automatically judges whether the module performance is qualified by combining the preset range, effectively identifying defects such as signal loss, and significantly improving the automation level, efficiency and accuracy of the test.

[0027] In this embodiment of the application, the test module 200 includes: a probe, a light-transmitting hole, and a probe-type cavity 1.

[0028] The probe is electrically connected to the plug-in terminal of the Hall module. The Hall module is placed in the probe-type cavity 1. The light-transmitting hole is opened at the bottom of the probe-type cavity and is located on the sensing path of the sensing module.

[0029] It is understood that in this embodiment of the application, the test module is set with a probe-type cavity for positioning and placing the Hall module. The probe and the plug-in terminal of the Hall module are reliably electrically connected to supply power and collect signals. At the same time, a light-transmitting hole is set in the probe-type cavity corresponding to the position of the sensing module, so that the sensing module can accurately detect whether the Hall module is installed in place, thereby ensuring the timely generation of the trigger signal and the automatic start of the subsequent detection process, improving the clamping stability, signal contact reliability and overall detection consistency and efficiency.

[0030] In the embodiments of this application, such as Figure 2 As shown, the sensing module 400 is a photoelectric sensor 2.

[0031] The photoelectric sensor 2 is located below the light-transmitting hole. It is used to block the photoelectric emission source located below the light-transmitting hole when the Hall module is placed in the probe-type cavity 1. The photoelectric sensor 2 detects the placement position of the Hall module and generates a corresponding trigger signal.

[0032] It is understood that in this embodiment, the sensing module uses a photoelectric sensor, which is located below the light-transmitting hole. When the Hall module is placed into the cavity containing the probe, it blocks the light-transmitting hole. The photoelectric sensor accurately identifies that the module has been placed in place because the light is blocked, and generates a trigger signal in time. This ensures that the detection process starts automatically after the module is correctly installed, thereby improving the reliability, response speed and automation of the detection.

[0033] In the embodiments of this application, such as Figure 2 As shown, the magnetic field simulation module 300 is a miniature DC motor 3, which is used to drive the magnetic ring 4 to rotate according to the control command issued by the control module, and provide a rotating magnetic field signal to the Hall sensor in the Hall module.

[0034] It is understood that the magnetic field simulation module in this application embodiment uses a miniature DC motor to drive the magnetic ring to rotate according to the instructions of the control module, thereby stably providing a rotating magnetic field signal consistent with the actual motor operating state during the test, effectively exciting the Hall sensor in the Hall module to output corresponding pulses, ensuring that the detection environment is close to the real working conditions, and improving the accuracy and reliability of the detection results.

[0035] In the embodiments of this application, such as Figure 2 As shown, the control module 500 includes: controller 5, relay, and Hall signal acquisition circuit.

[0036] The controller responds to the trigger signal from the sensing module, controls the magnetic field simulation module to operate and provide a rotating magnetic field signal, and uses the test module to collect the Hall pulse signals generated by the Hall module, counts the number of Hall pulse signals to generate a counting result, and generates a detection conclusion based on the counting result and a preset pulse count range; the relay is connected to the controller and is used to control the power supply of the Hall module under test and the magnetic field simulation module according to the controller's control instructions; the Hall signal acquisition circuit is connected between the signal output terminals of the controller and the Hall module under test and is used to acquire Hall pulse signals.

[0037] It is understood that in the embodiments of this application, the control module achieves automatic control and accurate judgment of the detection process through the coordinated operation of the controller, relay and Hall signal acquisition circuit. After receiving the trigger signal from the sensing module, the controller controls the power supply of the Hall module and the magnetic field simulation module through the relay, and drives the magnetic field simulation module to generate a rotating magnetic field. At the same time, the Hall pulse signal is acquired in real time through the Hall signal acquisition circuit, the number of pulses is accurately counted and compared with a preset range, and the detection conclusion is automatically generated, which effectively improves the automation level, detection accuracy and operational safety of the system.

[0038] In the embodiments of this application, such as Figure 2 As shown, the control module 500 also includes a power supply voltage acquisition circuit.

[0039] The power supply voltage acquisition circuit is used to monitor the system's operating voltage in real time, and drives the alarm to sound an alarm when the operating voltage deviates from the target voltage value.

[0040] It is understood that, in the embodiments of this application, the control module, through the integrated power supply voltage acquisition circuit, can monitor the system operating voltage in real time. When the voltage deviates from the target value, it immediately drives the alarm to issue an alarm, effectively preventing misjudgment or equipment damage caused by abnormal power supply, and ensuring the stability and reliability of the detection results.

[0041] In this embodiment of the application, a screen driving circuit is also included.

[0042] The screen driving circuit is connected to the controller 5 and is used to drive the external display screen to display the number of Hall pulses and / or the current alarm code according to the control instructions of the controller 5.

[0043] It is understood that, in this embodiment of the application, the control module, by adding a screen driving circuit, can drive the external display screen in real time to intuitively display the number of Hall pulses or the current alarm code according to the controller's instructions, so that the detection results and abnormal information are clear at a glance, making it easy for operators to quickly grasp the test status and handle faults in a timely manner, significantly improving the efficiency of human-computer interaction and system maintainability.

[0044] In the embodiments of this application, such as Figure 2 As shown, the detection system 10 of the Hall module sensor also includes: a pass indicator light 8 and an alarm 9.

[0045] Among them, the qualified indicator light 8 is used to light up according to the control command of the control module 500 when the identification count result is within the preset pulse number range, and the alarm 9 is used to issue an alarm according to the control command issued by the control module 500 when the identification count result exceeds the preset pulse number range.

[0046] It is understood that, in the embodiments of this application, after the control module completes the counting of Hall pulse signals, it can automatically determine the qualified status of the Hall module based on whether the counting result is within the preset pulse quantity range. If the result meets the requirements, it drives the qualified indicator light to light up to indicate that it has passed. If the result exceeds the range, it is determined to be unqualified and simultaneously triggers an audible and visual alarm and outputs the corresponding alarm code on the external display screen. This facilitates operators to quickly identify abnormal situations and significantly improves the intuitiveness, response efficiency, and fault traceability of the detection process.

[0047] In the embodiments of this application, such as Figure 2 As shown, the detection system 10 of the Hall module sensor also includes an oscilloscope signal acquisition port.

[0048] The oscilloscope signal acquisition port is used to provide Hall signals to the oscilloscope.

[0049] It is understood that the system in this application embodiment is equipped with an oscilloscope signal acquisition port, which can directly output the raw signal from the Hall module for observation by an external oscilloscope. This facilitates technicians to conduct in-depth analysis and verification of signal waveforms, timing and abnormal details, and provides auxiliary diagnostic means on the basis of automated judgment, thereby further improving the comprehensiveness and reliability of the detection.

[0050] In the embodiments of this application, such as Figure 2As shown, the Hall module sensor detection system 10 also includes a power interface 11 for connecting an external power source to provide power to the test module 200, magnetic field simulation module 300, sensing module 400 and control module 500 in the Hall module sensor detection system 10.

[0051] It is understood that the embodiments of this application connect to an external power source through a power interface, providing stable power to the test module, magnetic field simulation module, induction module, and control module, ensuring the reliable and coordinated operation of each functional unit, simplifying the power supply structure, and improving the system integration and ease of on-site deployment.

[0052] The detection system for the Hall module sensor proposed in this application realizes rapid detection without the need for installation in the motor cavity or wiring harness by detachably placing the Hall module in the test module, combining it with the magnetic field simulation module to provide a rotating magnetic field, and having the sensing module automatically identify the module's placement status. After receiving a trigger signal, the control module automatically drives the magnetic field simulation module to run and collect Hall pulse signals. By accurately counting the number of pulses and comparing them with a preset range, it effectively determines whether there is signal loss, significantly improving detection efficiency, automation level and detection accuracy.

[0053] The following will combine Figure 2 The detection system of the Hall module sensor in this application is described in detail below: The detection system of the Hall module sensor in this application includes a probe-type cavity 1, a photoelectric sensor 2, a miniature DC motor 3, a magnetic ring 4, a controller 5, a display screen 6, an oscilloscope signal acquisition port 7, a pass indicator light 8, an alarm 9, a main housing 10, and a power interface 11.

[0054] The probe-type cavity 1 includes: a probe, a light-transmitting aperture, and a product Hall module placed within it. The Hall module's plug-in terminals contact the probe for powering the Hall module and acquiring / transmitting Hall signals. When the Hall module is placed in the probe-type cavity 1 and blocks the photoelectric sensor located below the light-transmitting aperture, the photoelectric sensor 2 inputs a product detection placement signal. The probe-type cavity is customized according to the shape of the Hall product to be inspected and is removable and replaceable.

[0055] Photoelectric sensor 2 is used to detect whether the product to be inspected is placed in the correct position. The miniature DC motor 3 is controlled by the main controller. When the miniature DC motor 3 rotates, it drives the magnetic ring 4 to rotate, providing a rotating magnetic field signal to the Hall sensor in the Hall module. The control module includes: controller 5, relay, Hall signal acquisition circuit, power supply voltage acquisition circuit, and LCD screen driving circuit. When the photoelectric signal is input, the MCU controller relay activates, controlling the motor to rotate for 1 second at the rated 13.5V voltage, acquiring the number of Hall pulses, and comparing it with the accurate value. If the error is within a reasonable range, the qualified indicator light illuminates; otherwise, the alarm sounds. If the MCU detects that the power supply voltage is not 13.5V, the alarm will sound directly after the product to be inspected is placed in the Hall module.

[0056] Display screen 6 is an LCD (Liquid Crystal Display) screen used to display the number of Hall pulses and the current alarm code, such as a product malfunction error code or a power supply voltage malfunction error code. Oscilloscope signal acquisition port 7 provides a Hall signal acquisition port for an external oscilloscope. Pass indicator light 8 indicates that the Hall pulse count is within acceptable limits. Alarm 9 displays alarm information. Main housing 10 provides physical support for all system components. Power interface 11 is used to connect an external power supply.

[0057] The Hall module in this application does not need to be inserted into the motor cavity. The Hall module is placed in a probe-type cavity 1, with the plug-in terminals of the Hall module contacting the probes for power supply and Hall signal acquisition. When the Hall module is placed in the cavity and blocks the photoelectric sensor located below the light-transmitting hole, the photoelectric sensor sends a product placement signal to the controller. The probe-type cavity 1 is customized according to the shape of the Hall product to be tested and is removable and replaceable. After the photoelectric signal is input, the controller and relay activate, controlling the motor to rotate for 1 second at a rated voltage of 13.5V, collecting the number of Hall pulses, and comparing it with the accurate value. If the error is within a reasonable range, a pass indicator light illuminates; otherwise, an alarm is triggered. If the controller detects that the power supply voltage is not 13.5V, an alarm is triggered directly after the Hall module to be tested is placed in the cavity.

[0058] It can quickly and automatically detect signals without needing to insert into the motor cavity or connect wiring harnesses. It can identify whether there is a lost Hall signal and has an alarm function. It uses a miniature motor instead of a real motor, which is more energy-efficient, making the Hall module detection more efficient, energy-saving and accurate.
