Signal level Test and research of while drilling Print Circuit Board Based on CAN bus

To address accelerated failure and aging of key electronic circuits during drilling, a compact signal acquisition module has been designed for monitoring in limited underground space. Utilizing the dsPIC33EV128GM104 microprocessor and signal conditioning circuits, it processes measured signals and converts them with internal AD circuitry. The MCP2551 serves as the CAN transceiver for communication, allowing the module to transmit data to the host computer for real-time signal detection and status feedback, enhancing intelligent monitoring through high-speed and reliable data transmission.
