Mornsun Electric Vehicle Power Supply Design Reference

The difference between electric vehicles and traditional fuel vehicles lies in the power part, which is also the core part of electric vehicles. Pure electric vehicle systems usually include three systems, namely the electric drive subsystem, the main energy subsystem and the auxiliary control subsystem. Among them, the electric drive subsystem consists of an electronic controller, a power converter, an electric motor, a mechanical transmission device and drive wheels; the main energy subsystem consists of a main power supply, an energy management system and a charging system; the auxiliary control subsystem has functions such as power steering, temperature control and auxiliary power supply.

Thermometer based on face recognition

This work is a thermometer based on face recognition. The appearance of the work is a temperature measuring gun. The work is mainly composed of the K210 kit provided by Sipeed, Hetai HT32F52352 chip, WIFI communication module, cloud server, IC card reader module and LDO power module. etc., the K210 is controlled by the HT32 chip to collect images in real time, and the collected images are processed locally. If there is facial information in the collected images, the facial features are extracted based on the face model, and then compared with the person in the image library. Compare the feature values ​​of the face, and return the recognition results to the HT32 chip and the host computer for us to view the temperature measurement results. The following is a physical picture of the overall work and an introduction to its functions.

Contactless face recognition access control system

In the epidemic environment, people don't want to touch things outside, so we create a face recognition access control system that does not require contact. When it is detected that a person is approaching the door, the face recognition device is awakened to save power consumption. When the face recognition passes, the door is controlled to open.
