Monitoring system for electric vehicle charging and converting station

Abstract

The invention discloses a monitoring system for an electric vehicle charging and converting station. The monitoring system comprises a background monitoring layer, an in-situ monitoring management unit and a charging and converting device layer. An in-situ monitoring intelligent terminal is connected with a monitoring background through the Ethernet, data information of monitoring devices corresponding to charging devices are integrated and uploaded to the monitoring background, and the in-situ monitoring management unit is responsible for completing information integration of the charging devices and data interaction between the charging devices and the monitoring background. According to the monitoring system for the electric vehicle charging and converting station, the in-situ monitoring management unit is adopted to be responsible for and manage data exchange between the monitoring devices of the charging devices and converting devices and the monitoring background, and information exchange is conducted with the monitoring background according to the packed data transferring rule. Due to the fact that the monitoring devices share one in-situ monitoring management unit, the communication connection management between the monitoring background and the monitoring devices is greatly reduced, the reliability of the monitoring system is improved, and the number of the monitoring devices is increased.

Description

technical field [0001] The invention belongs to the technical field of computer network communication, and in particular relates to a monitoring system for an electric vehicle charging and replacing station. Background technique [0002] The charging and swapping station monitoring system is a "layered distributed" network structure, and its backbone network is Ethernet, which is interconnected through CAN bus, serial bus, wireless network (WIFI), RFID radio frequency identification and other communication networks distributed in different work sites. Construct. [0003] The overall network structure of the existing charging and swapping station monitoring system is as follows: figure 1 shown, from figure 1 It can be seen that the monitoring equipment of the charging and swapping station monitoring system generally includes sub-box chargers, vehicle chargers, battery swapping equipment, power distribution equipment, and vehicle sensing equipment, etc., and each device is i...

AI Technical Summary

Problems solved by technology

Each different sub-box charger has different communication configuration information. In the face of thousands of charging equipment, if these electrical quantities are implemented in the form of traditional measurement points, there will be configuration quantities in the specific project implementation process. Large, error-prone, difficult to manage, etc. If the configuration information of the charger is changed, the workload of the engineering staff will be doubled and disastrous

In addition, the monitoring background is the center of the entire equipment monitoring. If there is a temporary failure in the monitoring background, it will face the situation that the entire station equipment cannot be monitored and operated.
