Project Background

The intelligent upgrade of construction machinery, agricultural equipment, and special-purpose vehicles requires an information gateway device capable of long-term stable operation in harsh electromagnetic environments with strong vibration. This project aims to design an industrial-grade gateway controller PCBA for special-purpose vehicles, enabling real-time equipment status collection, remote monitoring, and data upload.

Key Hardware Requirements:

• Multi-Protocol Communication: Support for multi-channel CAN (including CAN FD), RS232/RS485, K-Line, and general-purpose I/O to interface with various vehicle sensors and control units

• Industrial-Grade Reliability: Wide operating temperature range (-40°C to +85°C), vibration resistance, and electromagnetic interference (EMI) protection

• Remote Data Transmission: Integration of 2G/4G, Wi-Fi, or Bluetooth modules for cloud data upload and mobile device configuration

• Data Acquisition: Support for analog/digital input and output for connecting temperature, pressure, speed sensors, etc.

• Power Supply Adaptability: Wide input voltage range (9-30V) to accommodate vehicle power fluctuations
