[Abstract]:Internet of things terminal equipment is the core component of Internet of things perception, and it is very important to the development of Internet of things. Most of the current Internet of things terminals are developed for the application of a particular field. The poor universality and compatibility restrict the use and promotion of the Internet of things terminal equipment. Based on this, the purpose of this paper is to develop a flexible interface and a certain universality of the Internet of things embedded terminal equipment, and to study its key technologies. The main contents are as follows: (1) in order to meet the requirements of multi-sensor access, the flexible configuration method of Internet of things embedded terminal supporting multi-sensor access is studied, and the corresponding hardware interface and communication protocol are designed. Middleware and application layer configuration tools, developed the Internet of things embedded terminal equipment, to achieve terminal interaction, configuration and other functions; (2) based on ZigBee protocol, using the task scheduling and message passing mechanism of Z-Stack, this paper studies the networking method of Internet of things node, and realizes the networking and wireless transmission function of Internet of things terminal equipment based on embedded system architecture; (3) the power consumption, parameters and performance of embedded Internet of things terminal device are analyzed in detail, and the power supply and working mode management mechanism of embedded terminal device are studied, and the low power consumption strategy of Z-Stack is combined. The energy efficiency management function of embedded devices is optimized. (4) according to the security requirement of Internet of things, this paper studies the isolation mechanism of Internet of things based on physical isolation, designs the corresponding operation mechanism and communication protocol, and develops the gateway equipment of Internet of things with physical isolation function. Under the background of cold chain logistics, the function of the system is tested and verified, and the features of ad hoc network, flexible sensor access, low power consumption and network security isolation are realized. The whole system has strong expansibility and is practical.
