[Abstract]:With the development of science and technology and the continuous improvement of people's living standards, intelligent electrical equipment has been popularized to ordinary people's families, which brings great convenience to people's life. Smart home integrates advanced computer technology, carrier communication technology, wireless communication technology and network technology, which organically combines home life with intelligent equipment to make people's life more comfortable, efficient and convenient. Intelligent switch is the core component of smart home. According to the actual needs of the family, this paper studies and designs a power line carrier intelligent switch, which can monitor household appliances remotely and in real time. In the aspect of hardware design, the powerful function, complete configuration and low power consumption CMOS integrated chip PL3106 are selected as the main control chip. The single chip microcomputer is embedded in the spread spectrum communication modulation and demodulation circuit, which simplifies the design of the peripheral circuit and reduces the cost. The small power switching power supply is used as the power supply system, which has the advantages of small volume and high conversion efficiency. The relay switch uses magnetic holding relay, which can keep the switch closed or disconnected under the condition of coil power outage, save electric energy and improve the overall performance-price ratio of the system. Power-off detection circuit can quickly detect whether the power grid power down. In order to cut off the relay switch in time when the power grid is turned off, the system can effectively avoid the great waste of electric energy caused by the work of household appliances when they call. Touch button instead of traditional mechanical button to realize the standard operation of terminal equipment, remote operation, beautiful and generous, durable, convenient and practical. The infrared receiving function is the extension of the terminal panel. The remote infrared remote control is used to realize the standard operation of the terminal and the remote operation. The infrared receiving module adopts the integrated receiving probe HS0038, to simplify the hardware design and reduce the cost. The power line carrier communication with wide coverage, high efficiency and low cost is used to realize the data transmission between the terminal equipment. A set of real-time intelligent switch monitoring system is constructed to display the working state of household appliances in real time and ensure the safe and stable operation of electrical appliances. The system adopts hardware anti-jamming measures to improve the anti-jamming performance and enhance the stability of the system. In the aspect of software programming, an embedded real-time multitask operating system is built, which can arrange CPU time reasonably according to the priority of different tasks. The system adopts the modular programming idea, there is no delay, no cycle waiting in the module, and it is integrated into zero. the corresponding functional module is executed by the corresponding functional function scheduling mark, which simplifies the multi-task scheduling, and the program structure is clear and does not need to wait. Strong real-time. According to the design of the software and hardware of the system, the prototype is made, and the prototype is tested in the simulated working environment. The experimental results show that the power line carrier intelligent switch designed in this paper meets the design requirements, and the operation is stable and reliable, and the real-time performance is good.
