Abstract

The invention belongs to the technical field of a communication system, and specifically relates to a CAN bus accurate timing and assembly line testing communication system and method which can achieve high-reliability, high-precision, assembly line type and hot plug type communication with a servo driver. The system comprises an actuator A, an actuator B, an actuator C, a driver A, a driver B, a driver C, a ground control power supply module A, a CAN bus communication interface card, a CAN bus timing communication system, a ground power power-supply module B and a CAN bus. The ground power power-supply module B is connected with the actuator A, the actuator B and the actuator C. The ground control power supply module A is connected with the driver A, the driver B and the driver C. The CAN bus is connected with the driver A, the driver B and the driver C. The actuator A is connected with the driver C, the actuator B is connected with the driver B, and the actuator C is connected with the driver A.

Description

technical field [0001] The invention belongs to the technical field of communication systems, and in particular relates to a communication system and method for CAN bus precise timing and pipeline testing Background technique [0002] The servo drive is a power device that drives the actuator of the servo mechanism. It is mainly used to receive the CAN bus command sent by the front-end device-the controller, and to drive the back-end device by converting the CAN command signal into a high-power drive signal in real time. actuator movement. And transmit CAN bus data to the controller in real time to complete command transmission and information feedback. It is one of the core components of the high-precision and high-speed operation of the servo mechanism. [0003] The CAN bus command signal sent and received by the servo drive has a command timing accuracy of millisecond level and a data transmission accuracy of microsecond level. How to test it with high precision has bec...
