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.

Embodiment Construction

[0021] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as Figure 2 ~ Figure 3 Shown is a structural diagram of an embodiment of the monitoring system for electric vehicle charging and swapping stations of the present invention. The entire system is divided into three layers, the background monitoring layer, the on-site monitoring management unit and the charging and swapping equipment layer. Each monitoring device of the whole station is connected to the on-site monitoring intelligent terminal through the Can port or serial port, and the on-site monitoring intelligent terminal is connected to the monitoring background through Ethernet. The communication protocol adopts the IEC104 message header, and the ASDU entity part of the message is sent in the form of a service package of the charging and swapping station.

[0023] The background monitoring layer is composed of servers, worksta...
