Problems solved by technology

[0002] At present, once the TCP link of the wireless module is disconnected during data interaction with the background server using the wireless module of the existing charging pile, the data uploaded to the server by the charging pile will be temporarily stored in the built-in cache of the wireless module chip. When the link is disconnected When the network signal is not good, and no new link is established for a long time, the cache space of the chip will gradually fill up, and the previously cached data will have to be cleared

Embodiment Construction

[0021] To make the present invention easier to understand, specific embodiments of the present invention will be further described below.

[0022] Such as figure 1 As shown, a charging pile wireless communication system includes a charging pile 100, a wireless module 200, and a server 300. The wireless module 200 includes a main control unit 210, a 2G wireless chip 220 and an SD card connected to the main control unit 210. Unit 230, 485 chip 240, the wireless module 200 performs data transmission with the charging pile 100 and the server 300 through the 485 chip 240 and the 2G wireless chip 220, respectively; the main control unit 210 includes a FAT file system connected in sequence The message queue processing unit 211, the message queue processing unit 212, the data upload and issuance unit 213, and the link detection unit 214. The message queue processing unit 212 is connected with a logic sequence processing unit 215, and the main control unit 210 uses the FAT file The syste...

Abstract

The invention relates to a wireless communication system for a charging pile. The system comprises the charging pile, a wireless module and a server, wherein the wireless module comprises a main control unit as well as a 2G wireless chip, an SD card unit and a 485 chip connected with the main control unit, and the wireless module transmits data with the charging pile and the server via the 485 chip and the 2G wireless chip respectively; the main control unit comprises an FAT file system unit, a message queue processing unit, a data uploading and transmission unit and a link detection unit communicating with each other in sequence, the message queue processing unit is connected with a logic time series processing unit, and the main control unit is connected with the SD card via the FAT filesystem unit and connected with the 2G wireless chip via the link detection unit. The system can ensure the integrity of data interaction between the charging pile and the remote server, and is smoother in data transmission and low in processing difficulty of an application layer of the server.

Description

Technical field [0001] The invention relates to the field of background data interaction between a charging pile and a server, and in particular to a charging pile wireless communication system and a communication method. Background technique [0002] At present, when the existing charging pile uses the wireless module to interact with the background server, once the TCP link of the wireless module is disconnected, the data uploaded by the pile to the server will be temporarily stored in the wireless module chip's own buffer. When the link is disconnected When the network signal is not good, a new link is not established for a long time, then the cache space of the chip will gradually become full and the previously cached data has to be cleared to store the current data, so that the charging pile can not be guaranteed. Upload the complete charging bill data to the server, resulting in incomplete bills and affecting profitability. And when the wireless link is restored, the tradi...
