[0017] Compared with the prior art, the present invention has the following technical effects:
[0018] This vehicle position recognition module innovatively adopts a core board plus a baseboard combination structure. This design rationally separates core functions such as data processing and logical judgment from basic functions such as power supply and communication, improving both the module's integration and reliability, and facilitating maintenance and upgrades. The core board focuses on data processing and logical judgment, using an STC microcontroller as its core, along with necessary peripheral circuits, clock circuits, reset circuits, etc., to ensure stable operation of the microcontroller and efficient execution of various instructions.

[0028] Example 1, please refer to Figure 1 The locomotive position recognition module includes a core board, a base plate, a wheel sensor pulse signal receiving unit, a bottom box door control unit, and an RS-485 communication unit. The core board uses an STC microcontroller as its core for data processing and logic judgment. The base plate is connected to the core board and has a power supply unit for powering the module. It uses a 12V power supply to power the entire module and is responsible for communication with external devices. The wheel sensor pulse signal receiving unit is located on the core board and is used to receive pulse signals emitted by the wheel sensors. The bottom box door control unit controls the opening and closing of the system bottom box door in real time and accurately based on the logic judgment results of the core board. The RS-485 communication unit is located on the base plate and is used to transmit the status of the magnets to the server in real time via RS-485 communication.
[0029] In this embodiment, the core board integrates a data cache unit, which is used to temporarily store the received wheel sensor pulse signals and data during the processing.
[0030] Data Processing and Logic Judgment: The STC microcontroller on the core board serves as the core processor, possessing powerful data processing capabilities. After receiving the pulse signals emitted by the wheel sensor through the wheel sensor pulse signal receiving unit, the microcontroller analyzes and processes these pulse signals according to preset algorithms and logic rules.
[0031] Data caching: To cope with data flow fluctuations during data processing, a data caching unit is integrated into the core board. This unit uses high-speed random access memory (RAM) to temporarily store received wheel sensor pulse signals and intermediate data generated during data processing. The existence of the data caching unit effectively avoids data loss caused by the data processing speed not keeping up with the data receiving speed, ensuring the continuity and stability of data processing.
[0032] In this embodiment, the base plate uses a 12V power supply to power the entire module and is responsible for enabling communication with external devices. The power supply unit on the base plate includes a voltage regulator circuit, which converts the 12V power supply into a stable voltage required by each component.
[0033] Power Supply Function: The baseboard plays a crucial role in providing a stable power supply to the entire module. The module uses a 12V power supply. The power supply unit on the baseboard first filters the received 12V power through a filtering circuit to remove noise and interference signals, ensuring power purity. Subsequently, a voltage regulator circuit converts the 12V power supply into different stable voltages required by various components within the module, such as providing a 5V operating voltage to the STC microcontroller on the core board and providing appropriate voltages to other peripheral circuits. This multi-stage power processing method ensures a stable and reliable power supply for the entire module under different operating conditions, guaranteeing its normal operation.
[0034] In this embodiment, the RS-485 communication unit has a data verification function to ensure the accuracy of the magnet status data transmitted to the server. Communication Function: The communication unit on the baseboard is mainly responsible for enabling communication between the module and external devices, with the RS-485 communication unit being the core component of the communication function. Through the RS-485 communication unit, the module can transmit the magnet status data processed by the core board to the server in real time according to a specific communication protocol.
[0035] In this embodiment, the bottom door control unit and the bottom door are electrically isolated from each other via a relay. Based on the logic judgment result of the core board, this unit drives the actuator of the bottom door through control signals, realizing the real-time and precise opening and closing of the bottom door. The bottom door control unit and the bottom door are electrically isolated from each other using a relay. The relay achieves electrical isolation between the control signal and the actuator through electromagnetic principles, effectively blocking electrical interference and ensuring the accuracy and reliability of the bottom door control.
[0036] Installation process
[0037] Core board and base plate assembly: On a clean, anti-static workbench, accurately insert the STC microcontroller core board into the corresponding slot on the base plate, ensuring the pins are in tight contact with the slots, without looseness or misalignment. Connect the base door control unit and actuator according to electrical specifications, and tidy up the protection control lines. Connect the RS-485 communication unit data line to the locomotive communication bus or server interface, controlling the line length. Correctly connect the 12V power supply, measure the voltage, and install overcurrent protection devices.
[0038] Running process
[0039] After connecting to a 12V power supply, the module's STC microcontroller performs self-tests and initialization. It checks the operational status of each hardware unit, such as whether the wheel sensor signal reception is normal, whether the storage unit is readable and writable, and whether the power supply voltage is stable. If an abnormality is detected, the microcontroller will issue an alarm signal via indicator lights or other means. When the locomotive passes the magnetic sensor, the wheel sensor continuously generates pulse signals, which are transmitted through the base plate to the wheel sensor pulse signal receiving unit on the core board. The receiving unit receives these signals in real time and filters them to remove noise interference. When the logic judgment unit determines that the locomotive has reached a specific position, the bottom box door control unit sends a control signal to the bottom box door motor through the control signal output interface of the base plate according to a preset control strategy. The drive module generates corresponding drive signals based on the locomotive position information, driving the bottom box door motor to achieve precise control of the bottom box door.
