CAN card and server SOCKET data transmission algorithm

Abstract

The invention discloses a CAN card and server SOCKET data transmission algorithm, comprising the following steps: step 1, judging whether a communication system or a network is available; step 2, a CAN card sending data to a transmission terminal CAS, and verifying the data according to a CAN receiving protocol; step 3, the transmission terminal CAS sending data to a server SOCKET, and verifying the data according to a SOCKET transmitting protocol; step 4, the server SOCKET transmitting data to the transmission terminal CAS, and verifying the data according to a SOCKET receiving protocol; and step 5, the transmission terminal CAS transmitting data to the CAN card, and simultaneously verifying the data according to a CAN transmitting protocol. The data transmission algorithm effectively solves the problem that most abnormal charging equipment in the present market cannot be used; and by adopting a distributed structure, the problems that a server wastes resources and the efficiency is low are solved, and the advantages, brought to the whole service logic, of distributed development are sufficiently reflected.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a SOCKET data transmission algorithm between a CAN card end and a server end. Background technique [0002] During the charging process of electric vehicles, the data information of the charging gun needs to be uploaded to the server through the transmission end, and at the same time, the client also needs to send the command information to the server to complete the control or monitoring of the charging process. , There are the following problems in the communication algorithm between the CAN data information of the client or the charging gun and the SOCKET of the server: 1. Some exceptions have not been resolved, and even some programs cannot operate normally; 2. Some programs do not have relevant algorithms, and It is to directly hand over the relevant calculation logic to the server, resulting in waste of server resources, low efficiency, and abnormal server data; 3. Fo...
