Abstract

The utility model provides a GPRS (general packet radio service) remote data acquisition terminal device, which comprises a CPU (central processing unit) module, a power module U3, an RS485 communication module TX and a GPRS communication module TX1. Client instruments support communication signals 2, data information on each instrument is transmitted to a GPRS remote data acquisition terminal through the communication signals 2, the GPRS remote data acquisition terminal transmits the received signals to a meter reading central server for storage through a GPRS mobile public network, and the GPRS remote data acquisition terminal comprises a clock module, a storage module, a remote signaling/pulse acquisition module, a remote metering acquisition module and a remote control output module port. The GPRS remote data acquisition terminal device is capable of directly realizing transmission of the data information read from the client instruments to the meter reading central server through the GPRS network instead of employing a concentrator for transfer, and has the advantage of lower invested cost of communication equipment.

Description

A kind of GPRS remote data acquisition end device

Technical field

The utility model relates to the liquid meter acquisition terminal, is a kind of GPRS remote data acquisition end device.

Background technology

Realize that by wireless network the application of data transmission and information processing is very efficient and convenient at present, but the acquisition mode of existing remote auto meter reading system is to send data by low pressure carrier wave or short-distance wireless sending module to concentrator with copying the data of getting, concentrator sends data message by telephone network, GPRS/CDMA etc. to the center of checking meter again, this long-distance meter-reading system complex structure, system applies cost height, poor reliability and the defective that exists dispersion shape environment multi-point and wide-ranging, that usable range is not concentrated to use.

The utility model content

The purpose of this utility model provides a kind of GPRS remote data acquisition end device, it can directly realize that by GPRS network copying and accepting data message from the client instrument sends to the central server of checking meter, no longer pass through the concentrator transfer, have the advantages that to reduce the communication apparatus input cost.

The utility model for achieving the above object, be achieved through the following technical solutions: a kind of GPRS remote data acquisition end device, comprise CPU module, power module U3, RS485 communication module TX and GPRS communication module TX1, the client instrument is for supporting the instrument of communication signal, to GPRS remote data acquisition terminal emission data message, GPRS remote data acquisition terminal moves public network with the signal that receives by GPRS and is sent to the central server storage of checking meter data on each instrument by communication signal; GPRS remote data acquisition terminal is provided with clock module, memory module, remote signalling/distant arteries and veins acquisition module, telemetry-acquisition module, remote control output port module.

Advantage of the present utility model is: realize copying and accepting the method that data message sends to the remote data acquisition terminal of the central server of checking meter from the client instrument by GPRS network owing to adopt directly, can be applicable to water,, heating power, the metrical information in fields such as vapour is copied and is got, need not pass through the concentrator transfer, and suitable measuring instrument disperses the multi-point and wide-ranging environment of shape to use, the structure of simplifying reduces the system data transmission cost significantly, the utility model can directly be installed and used in the area that the GPRS signal is arranged, do not need the wiring of line method and the construction of wireless base station, reduce the communication apparatus input cost.
