Embedded-system-based charging facility data acquisition terminal

Abstract

The invention provides an embedded-system-based and modularly-designed charging facility data acquisition terminal, which takes combination of various wired communications and wireless communications into consideration, supports a 5.8G wireless ad hoc networking technology with strong penetrating power, is configured with a special security module, supports automatic updating of programs and remote configuration, realizes intellectualization of operation management, and achieves secure data interaction among an electric vehicle, a charging facility and a smart power grid. The data acquisition terminal supports automatic alarm, automatic record generation, accident judgment and handling and the like, further has strong functions of on-line self-diagnosis, self-healing, self-adaption and task timing, and realizes the intellectualization of operation management.

Description

technical field [0001] The invention relates to a charging facility data collection terminal based on an embedded system design, which is suitable for intelligently interacting charging facility data collection among power grids, charging facilities, and electric vehicles, and belongs to the technical field of electric vehicle charging facilities. Background technique [0002] The development of electric vehicles has been generally established by countries around the world as an important way to ensure energy security and transition to a low-carbon economy. my country has listed electric vehicles as a strategic emerging industry and vigorously promoted its industrial application. In 25 domestic cities, my country has carried out pilot projects of demonstration, popularization and application of energy-saving and new energy vehicles in 25 cities, and carried out pilot projects of subsidies for private purchase of new energy vehicles in 6 cities. The Ministry of Science and Te...

Problems solved by technology

[0005] The existing charging facility data acquisition terminal technical solutions have the following problems: 1. The real-time, safe and high-speed information interaction requirements of electric vehicle charging services under the orderly charging requirements are not considered

Failure to meet the requirements for secure transmission, storage, and access of data

2. The communication environment where the charging facility is located is not considered. The charging facility is often located in a location where the wireless public network cannot cover, and the support for various communication combinations is not enough, especially the technical support for wireless automatic networking with strong penetration Not enough, did not realize the convenience, economy and operability of wireless ad hoc network

3. Most of the communication interfaces use private communication protocols, which have poor compatibility and do not meet the requirements of interconnection and interoperability

4. It cannot support automatic alarm, automatic record generation, accident identification and processing, online self-diagnosis, self-healing, self-adaptation, automatic program update, remote configuration configuration, and scheduled task functions at the same time, and the operation management is not intelligent enough
