Wireless intelligent home control system scheme based on GPRS
introduction With the continuous development of network technology and communication technology and the continuous improvement of people's life requirements, the realization of remote control of family intelligence has become an inevitable trend. The Ministry of Construction's Housing Industrialization Promotion Center proposes that the residential community should meet six intelligent requirements, including the implementation of automatic monitoring and management of safety and security : automatic alarm for residential fires and leakage of harmful gases; anti-theft alarm system should be installed with infrared or microwave. Various types of alarm detectors; the system should be able to network with the computer security integrated management system; the computer system can centrally manage and control the anti-theft alarm system. However, due to the immature wireless communication technology and high operating costs, the smart home controller and external network wireless communication technology have become an important factor leading to low market acceptance, and the characteristics of the GPRS system can solve this problem well. The GPRS network communication service is a data transmission communication service launched by the communication company. In the coverage area of ​​the GPRS network, the transmission distance is not limited, the communication cost is relatively low, and the transmission rate is fast. This paper deals with the background of home intelligence system and GPRS technology, analyzes their basic characteristics and the basic functions to be realized, and proposes a total solution based on GPRS wireless home intelligent control system. Finally, the hardware and software implementation methods of the system core GPRS chip are summarized. System architecture The popularity of network applications and the generation of various information appliances have made access to the Internet within the home no longer limited to a single PC. Each family will face how to transmit Internet data within the home and how to connect various home appliances. The problem, based on this, the smart home network came into being. The smart home network is the basic unit of the information society. In the future family, various household appliances will form a home LAN and access the Internet through a smart home controller. The market potential of the smart home network is extremely impressive, and several major manufacturers Intel, IBM, Microsoft and Sony have already been involved. Smart home network refers to the establishment of a communication network in a home, connecting various household appliances to each other, enabling remote use and control of all household appliances on the smart home network and any required information exchange, such as music and television. Or data, etc. The architecture of the smart home network includes home internal network systems, smart home controllers, and data communication between the smart home network and the external Internet network. Among them, the smart home controller is an important part of the smart home network , which plays a core role in management, control and communication with external networks. It is a system that integrates various subsystems related to home life through the home management platform, and is also a physical interface connecting the internal and external networks of the home intelligence, and completes the data exchange function between the home and the external communication network, and is also responsible for Management and control of home equipment. On the one hand, the smart home controller needs to provide a communication interface for the home internal wiring, which can collect the information of the home device, and process, automatically control and adjust; on the other hand, the smart home controller acts as a home gateway and also provides a network interface for the external connection. The home internal network and the external Internet network enable users to access the home internal network through the network and other means to achieve monitoring and control. In addition, the smart home controller should also have automatic alarm and other functions, that is, when an alarm signal is found, such as: someone is maliciously intrusive, the temperature is too high, etc., the controller can immediately process and send an alarm signal to the user. As shown in Figure 1, the smart home controller is the core of the system. ARM embedded system design can be used to automatically run and process data, and manage and control each control terminal through RS485 bus. And the controller realizes the communication between the home system and the external network through the GPRS module, so that the user can realize the remote control of the home system through the short message and the Internet, and at the same time, the controller also provides the human-machine interface to the user through the keyboard and the display screen, which is convenient. The user implements local control. The control terminal is composed of a small number of small control systems for controlling various household devices, and these small control systems are formed into a network through a control bus, connected to the smart home controller, and controlled by the smart home controller.
