Abstract

The invention discloses an electric car charging pile data acquisition system based on a WiFi radio over fiber (RoF) technology. The system comprises proximal units (100), distal units (110) communicating with the proximal units (100) through optical fiber links (105), sink node charging pile modules (120) communicating with the distal units (110) through radio signals, and terminal charging modules (130) communicating with the sink node charging pile modules (120) through radio signals. The system provided by the invention is reliable in operation and flexible in design.

Description

【Technical field】 [0001] The present invention relates to the field of wireless network communication, in particular to a wireless switching system, and more particularly to an electric vehicle charging pile data collection system based on WiFi optical wireless technology. 【Background technique】 [0002] As we all know, electric vehicle charging piles for charging electric vehicles can be seen everywhere in real life. Electric vehicle charging piles have the characteristics of large number, many distribution points, small amount of communication data between charging piles and the main control system, and high requirements for operational reliability. [0003] The main control system usually needs to collect the data of electric vehicle charging piles in order to control these electric vehicle charging piles in a targeted manner. The existing electric vehicle charging pile data acquisition system has the disadvantages of unstable operation and poor structural design flexibi...
