Wireless meter reading system based on Ad Hoc

Abstract

The invention discloses a wireless meter reading system based on Ad Hoc, belonging to the technical field of wireless communication. The wireless meter reading system comprises terminal acquirers, a central node and a host computer meter reading center, wherein the terminal acquirers are in charge of acquiring data on meters and transmitting the acquired data to the central node; an Ad Hoc network is formed by the terminal acquirers, the central node and the terminal acquirers; the central node is in charge of distributing network addresses, receiving the data acquired by the terminal acquirers, establishing wireless communication connection with the host computer meter reading center through a GSM (Global System for Mobile Communication) module, and transmitting or receiving the data and control signals; and the host computer meter reading center is in charge of receiving and managing data transmitted from the central node, and transmitting control signals to the central node. The wireless meter reading system can automatically alarm and prompt wrong nodes when the nodes have faults, and simultaneously has the advantages of low construction and maintenance expense, high reliability, low power consumption, easiness in implementation and the like.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to an Ad Hoc-based wireless meter reading system. Background technique [0002] With the continuous development and progress of society, more and more automation technologies have been introduced into people's production and life, and this tendency is also reflected in the aspect of automation instruments. With the increasing application of various instruments in different occasions, the collection and management of instrument data has become an issue that people are more and more concerned about. [0003] The early meter reading methods were manual meter reading on site. The meter reading staff had to go to the user to read the data, and then manually re-enter the data into the computer for processing. This method of meter reading works well when the number of meters is relatively small and the location of the meters is relatively concentrated, but for the situation w...

AI Technical Summary

Problems solved by technology

Since the power line is a non-communication line, its interference and attenuation are very large, so the reliability of power line carrier data transmission is very low, and the bit error rate is high.

[0010] ZigBee network meter reading system: ZigBee is a network working at 2.4GHz. Although it has many advantages such as high transmission rate and rich communication protocols, ZigBee has the same frequency interference with WiFi and Bluetooth, as well as relatively low penetration and sensitivity. Poor, unsatisfactory distance, difficult to adapt to actual requirements

[0011] To sum up, the existing wireless meter reading system mainly has the following disadvantages: in the process of data transmission, due to uncertain factors such as co-channel interference, transmission distance, and physical properties of penetrating objects, the final data will be lost or incorrect. Accurate; the transmission data rate and communication range are small, not suitable for carrying large data services, and service expansion is not considered; whether it is the initial capital investment or the later transformation investment, the cost is high

If there are too many nodes, the capital investment will be more, which is not conducive to practical application
