In view of the deficiency of traditional entrance guard control, a more convenient intelligent entrance guard control system suitable for home remote control is designed. WeChat small program development is adopted at the front end of the system，and the management control center is built by cloud server, and the hardware controller is designed with Raspberry Pi,which is an embedded development board with low power consumption and high performance. The functions of user management, device management and unlocked control are realized. The response performance and safety performance of the system are optimized and the response time is reduced.

Introduction

In recent years, the wave of themes of smart cities, smart life, and smart homes has constantly impacted the traditional access control system, resulting in the constant enlargement of traditional access control deficiencies.For password lock,it is cumbersome,the password is easy to leak, the security is low and we got less using scene.For magnetic card, it is prone to the phenomenon that the key is forgotten.Also, the magnetic card has the disadvantages of being easily damaged and demagnetized.For biometric access control, the cost is high. It also has a high requirement for users and the using environment, because the users’ characteristics change will lead to unrecognized phenomenon[1]. With the widespread use of WeChat, it is of great significance to develop a convenient access control management system based on mobile devices with excellent security performance and compatible performance using small programs born in the WeChat ecosystem.
