Based on GPRS and Internet technology to realize the remote intelligent meter reading system, collection terminal of upward communication USES the ZigBee wireless sensor network technology, through the network and the data concentrator number. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the intelligent remote meter reading system based on GPRS technology design and research, the article details. Intelligent village is an important part of national information infrastructure. Based on GPRS and Internet technology to realize the remote intelligent meter reading system, collection terminal of upward communication USES the ZigBee wireless sensor network technology, through the network and the data concentrator interaction to achieve electric meter data remote transmission of data. System with the water, electricity, gas and other resources of the automatic metering and charging and real-time monitoring function, can accurately realize the user data collection, storage, display and transmission, reliable operation, has a certain application promotion value. Modern family water, electricity, gas meter, commonly known as & other; Three table & throughout; 。 Of the traditional meter reading not only brought inconvenience to the user, and take up a lot of human resources, cause, the difficulty of charge; Emerging IC card technology, relatively thoroughly solve the problem above, but for the user to buy & other; Water, electricity, gas & throughout; It's not very convenient, at the same time and the use of user information for real-time communication, so smart meters and security monitoring has become the developing direction of the industry. To smart meters and security monitoring must build the network of data transmission. Traditional data transmission are mainly digital radio set, dial, satellite communications and auxiliary line, etc. , these transport are in a small range of real-time performance, high investment and operating cost. GPRS technology and the development of Internet technology, Internet is industrial monitoring, telemetry remote data transmission and data in the field of network management has provided a broad platform. 1, the system builds system requires a connected to the Internet Internet data center, and & other; Three table & throughout; Or need to monitor the equipment of data collector and a built-in GPRS module connected to the microprocessor. Collector for data transmission to the microprocessor, the microprocessor through GPRS module landed on the GPRS network after CGSN gateway to transmit data to the Internet data center, and complete the data transmission. The system consists of the database server, data service center, terminal operation, concentrator and the collector of 5 parts, such as system structure is shown in figure 1. Collector information center is located in the residential quarters, customer & other; Three table & throughout; Using the data first by ZigBee technology to transmit data to the concentrator, located in the center of the village information concentrator through RS232 interface is connected with GPRS transparent data transmission terminal. Through GPRS transparent data transmission terminal built-in embedded processors to deal with data, protocol encapsulation backwardness to the GSM network, through the GPRS network transmits to the database server, implementation & other; Three table & throughout; Data and data center system of real-time online connection. 2, technical route based on the system function requirement, the hardware system should include: the user three table data acquisition module, display module, the unit circle data set of ZigBee wireless data transmission network, wireless data transceiver modules & other The client & throughout; With the wireless data transceiver module, RS - 232 serial interface circuit, superior management of computer & other; Data center & throughout; Two parts. “ The client & throughout; With & other; Data center & throughout; Through the wireless transceiver module of the wireless network to realize data exchange. 1 data acquisition display modules, data acquisition module includes: the user of electricity acquisition and acquisition and display circuit, display circuit, the user water user gas acquisition and display circuit three dosage forms. This system adopts the ADI's single chip power metering ADE7751 and special chip microprocessor designed to rate more than all electronic watt-hour meter to realize user power consumption data acquisition; The nanjing di thayer instrument mechanical and electrical equipment production of impulse type intelligent vortex flowmeter sensor and microprocessor designed digital meter and pulse type intelligent vortex flowmeter sensor and microprocessor designed digital gas meter for data collection, storage, calculation, display, transmission and other requirements. Unit 2 concentrator module to facilitate the function of the wireless set copy this design in each in each cell of the circle to join a unit concentrator. Unit concentrator with each data acquisition unit by ZigBee wireless data transmission network, is used to implement each customer & other; Three table & throughout; Timing data receiving and storage, it is & other; Three table & throughout; With a core part of the wireless transceiver module. The use of unit concentrator greatly simplify the complexity of the wireless data transmission network, reduces the system cost. System is mainly composed of main controller, GPRS module and ZigBee rf communication module of three parts, the structure diagram is shown in figure 2. Main controller USES the samsung ARM9 microprocessor S3C24 - 10 x, it has the function of peripheral extended module, can realize high speed processing. GPRS module adopts Siemens TC35 terminal, via a serial port connected to the CPU, with Internet connection. ZigBee rf transceiver module adopts ChipconAS company CC2420 chip, control within the collector has the ZigBee standard interface detection equipment.
