Description

A kind of wireless long-distance meter-reading system based on ad hoc multihop network

Technical field

The utility model relates to electric field, is specifically related to a kind of wireless long-distance meter-reading system based on ad hoc multihop network.

Background technology

Traditional Man is checked meter has to the doorstep increased the handling cost of department, nowadays can adopt the remote meter reading technology.

At present the wireless communication technology that adopts of radio meter register mainly is the point-to-point or point-to-multipoint such as (bluetooth, 802.11), and without routing function, zigbee has routing function, but the zigbee transmission range is too short, and performance through walls is too poor, coverage is little.

The utility model content

A kind of wireless long-distance meter-reading system based on ad hoc multihop network of the present utility model can provide real-time, efficient, reliably data transmission communication, realizes that the robotization of ammeter, water meter, gas meter, hotlist data is copied and accepted and monitored.

Concrete technical scheme is as follows:

A kind of wireless long-distance meter-reading system based on ad hoc multihop network, described wireless long-distance meter-reading system comprises at least one data collection station and a data concentrator, and data collection station comprises the governor circuit module and metering detection module, ad hoc network communication module, the LCD display module that is connected with governor circuit respectively and the power module that is connected with each several part; Data concentrator comprises that single-chip microcomputer reaches storer, ad hoc network communication module, GPRS or the cdma network communication module that is connected with single-chip microcomputer and the power module that links to each other with each module.

Wherein, described governor circuit is central control processor, comprises single-chip microcomputer and data-carrier store FLASH and RAM.

Described metering detection module links to each other with the serial ports of governor circuit by 485 buses; Ad hoc network communication module, LCD display module reach with power module and are connected governor circuit by data bus, address bus and control bus separately respectively.

Described power module, its input end are the 220V alternating current of electric system, are low-voltage DC by transformation, filtering, rectification, become the final power supply source of data collection station and data concentrator.

Described LCD display module is directly driven by single-chip microcomputer, is used for showing parameters and the meter reading data of gauging table.

Described ad hoc network communication module has autonomous networking and routing function, the network that can automatically form the mesh structure, as long as enter in effective areal coverage of ad hoc network with the meter-copy device of ad hoc communication module, can finish data acquisition and wireless transmission to meter-copy device in the areal coverage by the routed path of mesh structural network.

Described GPRS or cdma wireless communication module, an end is connected to the serial data interface of single-chip microcomputer, and the other end carries out exchanges data with these administration and supervision authorities of server and workstation on upper strata and communicates by letter.

The beneficial effects of the utility model are:

The utility model adopts Ad Hoc network to carry out the terminal networking, has both rejected this link of loaded down with trivial details wiring, provides cost savings again, and maintainability strengthens greatly simultaneously.Ad Hoc does not rely on default infrastructure and sets up, and mobile node utilizes the wireless transmitting-receiving equipments exchange message of self in the network, when each other not in communication range each other, can realize multi-hop communication by other intermediate node relayings.Because Ad Hoc network characteristic can be added in network and the deletion data collection station easily.
