【Abstract】 Based on the characteristics of shield-driven tunneling, the functionality and realization of a controller area network bus(CAN)-bus-based monitoring system is first proposed in this study. The 87C52X2 and SJA1000 chips are accordingly utilized as sub-nodes of the monitoring system, which comprises hardware and software components. Finally, it is revealed that, during shield-driven tunneling, this system possesses such high performances as real-time monitoring, data transmission, anti-disturbance, simple structure configuration and complex model processing.更多还原
