System and method for obtaining of real-time state of charging pile

Abstract

The present invention discloses a system and a method for obtaining of a real-time state of a charging pile. The system comprises a state monitoring module, a TCP module, a collection front server, aRedis memory database and an application program. The state monitoring module is configured to monitor the state of each charging pile in real time. The TCP module is configured to upload the state message of the current charging pile when the state monitoring module monitors the change of the state of the charging pile. The collection front server is configured to receive the charging pile statemessage uploaded by the TCP module and is configured to convert the charging pile state message to a charging pile state message in a JSON format and upload the charging pile state message through a WebSocket communication mode. The Redis memory database is configured to store the charging pile state message in the JSON format. The system and a method for obtaining of the real-time state of the charging pile employ the WebSocket communication mechanism to achieve more efficient and real-time update of the charging pile state.

Description

technical field [0001] The invention relates to the fields of charging piles and mobile communications, in particular to a system and method for acquiring real-time status of charging piles. Background technique [0002] With the rapid development of charging pile technology and the popularization of mobile communication, it has become a trend to use APP (application program) to control charging piles to charge electric vehicles. At present, the APP of the charging pile mainly uses the map point method to display the charging pile. The coordinates of the point indicate the location of the charging pile, and the color of the point indicates the status of the charging pile (such as charging, idle, fault, etc.). When looking for charging piles on the map, users can find available charging piles according to the color of the point. [0003] The current mainstream charging pile APP is based on the HTTP polling (Polling) mechanism. The charging pile APP creates a timer, regularly...

Problems solved by technology

[0005] First, the scope is limited: when the number of charging piles in the entire system reaches 1000, 10,000 or even 100,000 levels, the status of all charging piles will be updated at one time, and the transmission data will be large and take a long time. Therefore, the system can only use a partial update method to update the range specified by the user. This has certain limitations. When the user moves the map to find a charging pile outside the specified range, the status of the charging pile obtained is not real-time, which makes the charging pile found by the user based on this query information unavailable. use

[0006] Second, waste of resources: each HTTP request and response has complete HTTP header information. In the case of a small amount of single update data, the overhead of HTTP header information is relatively large

Moreover, the APP sends requests to the server regularly, and the status of the charging pile on the server side may not be updated, which will bring a lot of unnecessary network transmission and occupy CPU resources.
