Abstract

The invention relates to an automation control system based on CAN buses. The automation control system is composed of a microcontroller, at least one CAN controller and a USB module. Each CAN controller is connected to each CAN bus. Data are transmitted between the microcontroller and a PC through a USB bus so that CAN message receiving and transmission can be achieved. An automation service program is executed on the PC, and an automation client terminal based on the PC can receive and transmit a message through an automation server so that the target CAN bus can be controlled.

Description

technical field [0001] The invention relates to automation in the field of electronic technology, in particular to an automation control system based on CAN bus. Background technique [0002] As the communication interface between various microcontrollers, the CAN bus is widely used in automobiles and industries; in the application process based on the CAN bus, it is necessary to receive and send specific messages through the CAN bus, so as to realize the control of a certain device. automated operation. [0003] The automation control based on CAN bus usually writes a specific application program on the PC, and connects the hardware with CAN interface through the USB to CAN interface card, so as to realize the control of the lower computer through the application program on the PC side. The disadvantages of this method are: 1. The scalability is not strong. If you need to add new functions, you need to modify the current application program or develop another application p...
