Charging pile with fingerprint recognition and payment system

Abstract

The invention discloses a charging pile with a fingerprint recognition and payment system. The charging pile comprises a fingerprint image collecting module, an image processing module, a control module, a communication module, a local data storage module, a back-end server and a MCU. Firstly, the image processing module preprocesses fingerprint images collected by the fingerprint image collectingmodule to make the images more clear, then the fingerprint images are subjected to feature extraction through a fingerprint feature point extraction algorithm based on binary images, extracted feature information is compared with fingerprint information preset in the local data storage module or the back-end server, a successful comparison signal or a failed comparison signal is output, and a control circuit triggers or closes a charging circuit of the charging pile according to the comparison results. Compared with the prior art, the charging pile has the beneficial effects that in the process of using the charging pile by a user, an electric vehicle can be charged easily and conveniently without carrying secret keys such as an RFID card, and meanwhile, safety and reliability in the using process are also improved.

Description

technical field [0001] The invention belongs to the technical field of charging pile control, and in particular relates to a charging pile with a fingerprint identification and payment system. Background technique [0002] At present, electric vehicles are becoming more and more popular, and the supporting charging piles are also widely appearing in various places. Most charging piles on the market use RFID cards for charging operations. RFID cards are the only proof of identification of users. If it is lost, the electric vehicle cannot be charged, and the balance in the RFID card is very likely to be stolen by others, and the procedures for replacement are more complicated, which will bring money loss and inconvenience to users. [0003] The RFID card itself also has some defects. If it is often in contact with magnetic objects such as mobile phones, the RFID card will fail due to degaussing; it cannot be bent, and it is easy to cause problems such as surface silk screen we...

[0002] At present, electric vehicles are becoming more and more popular, and the supporting charging piles are also widely appearing in various places. Most charging piles on the market use RFID cards for charging operations. RFID cards are the only proof of identification of users. If it is lost, the electric car cannot be charged, and the balance in the RFID card is very likely to be stolen by others, and the procedures for replacement are more complicated, which will bring money loss and inconvenience to users

[0003] The RFID card itself also has some defects. If it is often in contact with magnetic objects such as mobile phones, the RFID card will fail due to degaussing; it cannot be bent, and it is easy to cause problems such as surface silk screen wear due to wear and tear.

[0004] In modern society, everyone will have multiple cards, such as ID cards, bank cards, membership cards, etc. There are many types of cards, which are inconvenient to manage and easy to lose
