Embodiment Construction

[0024] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The invention provides a communication method based on the CAN protocol.

[0026] refer to figure 1 , figure 1 It is a schematic flow chart of the first embodiment of the communication method based on the CAN protocol.

[0027] In this embodiment, the communication method has the following steps:

[0028] Step S10, the first chip continuously transmits communication data to the second chip through the CAN protocol;

[0029] In this embodiment, the communication data in the CAN protocol includes at least state data, which stores the state information of the chip at a certain moment, and the state of the corresponding chip at that moment can be known according to the state data at a certain moment. The communication method based on the CAN bus communication protocol is applied to the welding system. The weldi...

Abstract

The invention discloses a CAN protocol based communication method. Data in the CAN protocol at least comprise state type data. The communication method comprises the following steps: a first chip continuously transmits communication data to a second chip through the CAN protocol; if the second chip receives the communication data transmitted by the first chip for at least one time within a first preset time, the second chip determines the state of the first chip based on the current state type data of the first chip in the received communication data; and if the second chip does not receive any communication data within the first preset time, the second chip determines transmission between the first chip and the second chip is abnormal and enters an alarm state. The invention also discloses a CAN protocol based communication system. According to the CAN protocol based communication method and system, information interaction of the system is realized based on the CAN protocol, the link connection is simplified, and stability and security of the system are improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication method and system based on the CAN protocol. Background technique [0002] Tri_arc welding system is a digital welding system with high efficiency and low heat input. The system consists of a digital power supply composed of three inverters, two wire feeders, a hand-held controller, welding process monitoring and welding data management PC host computer interface and automatic Composition of welding plane. The working current during the welding process is 500 to 1000A, and the three inverters will generate strong pulse interference during the inverter process, which will affect the normal operation of the entire welding system. In order to reduce the adverse effects caused by pulse interference, the welding system currently uses traditional parallel communication, and its anti-interference ability will be stronger than CAN communication. However, the wirin...
