EC20 based multi-node charging complex communication system

Abstract

The invention discloses an EC20 based multi-node charging complex communication system which comprises a transmission module, a special telephone module, an official communication module, a video monitoring module, a wireless alarm communication module, a user charging information module, a communication module and a broadcast module, wherein the transmission module is used for providing an encryption service, a decryption service and a content verification service for data transmission in one or more of the telephone module, the official communication module, the video monitoring module, a clock module, the wireless alarm communication module, the user charging information module, the wireless communication module and the broadcast module; the special telephone module is used for providing service contact, command routing and conference initiation services between senior executives in a charging complex operator. According to the EC20 based multi-node charging complex communication system disclosed by the invention, by integrating all information and mobile departments, comprehensive management of the charging complex and uniform arrangement are realized, the mobile time is shortened, the intermediate links are reduced, and the loss is lowered.

Description

technical field [0001] The invention relates to the field of charging communication, in particular to an EC20-based multi-node charging pile communication system. Background technique [0002] Charging pile, its function is similar to the fuel dispenser in the gas station, can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) Levels charge various models of electric vehicles. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. However, the power of the charging pile is fixed, so the compatibility is poor, and it is impossible to charge vehicles with different power requirements. Secondly, the charging pile has poor adaptability and cannot meet the needs of the rapid development of battery technology, which may easily lead to the unsustainable use of the charging equipment invested. In order to c...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that in the prior art, each communication channel of the charging stack is designed separately, and its compatibility is poor, and when the charging stack has problems such as failure, fire, theft, etc., the response time is too long , the loss is increasing, the purpose is to provide a multi-node charging pile communication system based on EC20, link the various communications related to the charging pile through one system, and ensure that problems such as faults, fires, and theft are notified to various departments at the same time. Perform their duties, shorten reaction time and reduce losses
