Technical Field

The utility model relates to a fill electric pile technical field, specifically be a fill electric pile private network centralized management equipment based on CAN bus communication.

Background

Most of the currently used R485 communication technologies mainly have the following disadvantages:

the RS485 is a half-duplex communication technology, and is divided into a single master-slave structure, namely, only one host can be arranged on one bus, communication is initiated by the host, no command is sent, other nodes cannot send information, the host can inquire the next node after the answer is sent, otherwise, a plurality of nodes send data to the bus, the data of the bus is easy to be disordered, and the bus utilization rate is extremely low.

2, RS485 communication has no perfect error detection mechanism, because it only defines the physical layer and has no data link layer, so he cannot identify the error, which easily causes a node to be damaged, sends data to the bus by party, causes the bus to be paralyzed, and the most common problem is that the whole bus is paralyzed when a node is damaged, commonly called as "deadlock".
