Embedded Wireless Concentrated Heat Meter Management System Design And Implementation

Our country's rapid economic development,making significantly improve people's living standards,centralized heating supply has become a trend,the Government has been part of our country at the beginning of the promotion of urban and rural areas.Centralized approach is no doubt that the heating to save energy and reduce environmental pollution of the atmosphere,but also can improve the livelihood of the people.But for ordinary heating users,by building housing area or by heating the effective area to calculate the cost of heat is not cost-effective,and is currently an urgent need for our country in accordance with the actual use of heat to the management fee.Based on the current status of the case,we propose the design of a centralized management system tables are hot very much in line with actual demand.Large-scale multi-user hot table centralized management required for high-load data processing,general industrial grade single-chip hard to be able to achieve the ability to deal with this.With the progressive development of embedded systems mature,with high processing speed of the embedded chip can do to focus on the hot meter management ability to handle high data volume requirements.This thesis is the study of similar products at home and abroad under the premise of a focus on embedded wireless hot table management system,the system combines the latest technology in today's hot technologies,including embedded Linux systems,GPRS wireless communications and remote ZIGBEE close range wireless communication technologies.Hot form for the application of industry-specific environmental requirements,the system uses the current market more popular ARM9 embedded processor S3C2440A and embedded Linux systems,the formation of a complete set of hardware and software combination of information collection system.User-friendly information for inquiries and to pay the cost of hot form,the system uses radio frequency RFID technology,each user has a non-contact RF card,the user's information hot table is stored in on this card.ZIGBEE the system through the wireless network will be hot in the region to copy table data on access to the terminal equipment,embedded systems,after the classification of data collation,and ultimately long-range wireless communications through the GPRS network will handle data sent to the information server,the server on Analysis of running database management software,after a powerful information will eventually deal with the user information after the Web browser to display the form to the user.This thesis mainly in the following aspects in detail and to do research work:First of all,for embedded Linux system,from the system and cross-platform build environment set up to compile the kernel and file system transplantation Construction,the paper formed a complete set of its own development platform.Innovation in science and technclogy,the system combines the most advanced wireless communications technology,will be the perfect ZIGBEE technology and GPRS technology together to solve a short distance and long-distance wireless communication problem.RFID radio frequency technology at the same time integrated into the system,the more enhanced the scientific and technological content of the system.Innovation in the software,the system uses a modular design,while the use of multi-threading and network programming in.perfect integration,the implementation of the information of the long-range multi-channel high-speed transmission.
