Data transfer system based on electronic information technology

Abstract

The invention discloses a data transfer system based on an electronic information technology. The data transfer system comprises a master station, a concentrator, a collector and a Zigbee wireless sensor module, wherein the master station is in communication connection with the concentrator by means of a GPRS wireless module, the concentrator is connected with the Zigbee wireless sensor module and a router, and the collector is connected with the other end of the router, the other end of the Zigbee wireless sensor module and a plurality of wireless transmission modules. According to the data transfer system based on the electronic information technology, a communication distance of the data transfer system can be up to 500 m in the non-routing case by using the Zigbee wireless sensor module and adopting an application-free 2.4GHz communication frequency band, a network protocol adopted by the data transfer system has functions of automatic network organization, automatic routing, network self-healing and the like, the communication problem between the concentrator and the collector can be solved, the electromagnetic compatibility problem of hardware and the anti-interference problem of the system are fully considered in design, the stability of system operation is significantly improved, and the data transfer system is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a data transmission system based on electronic information technology. Background technique [0002] The traditional manual meter reading method is time-consuming, laborious and requires remote automatic meter reading system. The centralized meter reading system for residential users has been developed for more than ten years in China, but it has not yet been widely applied. The main reasons are as follows: [0003] (1) The use of wired RS-485 bus or field bus has disadvantages such as inconvenient wiring, easy to be affected by natural and human factors, and heavy maintenance workload; (2) The power line carrier communication method is used between the concentrator and the collector. The extensive use of linear loads has a negative impact on the power line carrier, especially the spread spectrum power line carrier signal, making its data transmission unstable; (3) The traditional ...

[0003] (1) The use of wired RS-485 bus or field bus has disadvantages such as inconvenient wiring, easy to be affected by natural and human factors, and heavy maintenance workload; (2) The power line carrier communication method is used between the concentrator and the collector. The extensive use of linear loads has a negative impact on the power line carrier, especially the spread spectrum power line carrier signal, making its data transmission unstable; (3) The traditional 430MHz wireless communication scheme is used between the concentrator and the collector, and the software is compiled by itself to realize network routing And the communication protocol of the network organization, its stability and reliability cannot be guaranteed
