Design And Study Of Mobile Multifunctional Intelligent Controller

The article introduces a design and a study about household appliance control, based on the embedded controller single chip PIC16F877 made by Microchip Corp. It can control over lighting system in room, TV, security system, Fan system used in Chinese kitchen. The design for the embedded real time controller has been given in detail.In hardware part of system, the article introduces several parts as follows: the design of hardware in main module and subordinate module, remote controller. In the part of software, the introduction has been included the design and flow of not only main module but also subordinate module, infrared remote controller. Some classic programs has been analyzed. Coinstantaneous communication has been realized between main module and subordinate module based on the study for infrared communication protocol. A method of software decode based on ispLSI1032E has been put forward. It can let products to be upgraded easily. It also has some value to be popularized on market because of the reduction on cost.The fundamentals in embedded system are based on the principles of the design of hardware for this embedded multiple controller system. The fundamentals in modularize programmed thinking are used in the design of software. So, both the software and hardware are perfectly matched in this system. Thus, the state for whole system has been tested on stable running and convenient for maintenance. The function of surveillance , infrared remote controller , remote control online , are running very well . The data for temperature and voltage are disposed correctly. The expected object mentioned before has been achieved.
