Abstract

The utility model provides a GPRS (general packet radio service) remote data acquisition terminal. Meters supporting communication are arranged at an instrument terminal; all the meters exchange data with the GPRS remote data acquisition terminal by communication; the GPRS remote data acquisition terminal is in communication with a meter reading centre server by a GPRS mobile public network; a clock module provides a hardware calendar clock and a software self-programming clock run by the terminal; a storage module stores all the set parameters of terminal and the read data of the meters; a power module charges for supplying power for the terminal to run; an RS485 module is in communication with the meters and used for reading required data of the meters; a GPRS module sends the read data to the meter reading centre server; and a remote signal/remote pulse acquisition module, a remote detecting and acquisition module and a remote control output module are arranged on the terminal and used for expanding functions. The GPRS remote data collecting terminal has the advantages of being low in cost, simple in installation, convenient in use and the like.

Description

A kind of GPRS distant place data collection station

Affiliated technical field:

The utility model relates to the wireless data acquisition terminal of water, electricity, heat, gas industry, a kind of specifically GPRS distant place data collection station.

Background technology:

Current, along with the development of Internet of Things is promoted, the intelligent meter data recording field realizes that by wireless network data transmission, information processing use ubiquitous, being starved of the wireless network that a customer group covers extensively, communication is reliable, efficiently friendly helps to realize copying and accepting the information data that needs from the client instrument, China Mobile's GPRS network is apparent in the advantage of communication field, can satisfy its requirement.

At present, the mode that remote auto meter reading system both domestic and external generally adopts is: after terminal is copied and got instrumented data, data are sent data by low pressure carrier wave, RS485 interface or short-distance wireless sending module to concentrator, and concentrator sends data by telephone network, note, GPRS/CDMA etc. to the central server of checking meter again.This long-distance meter-reading system cost height, low, the complex structure of reliability, and can not satisfy instrument distribute do not concentrate, multi-point and wide-ranging, as the demand of mountain area, small towns, running environment occasion such as trans-regional.

The utility model content:

The purpose of this utility model is the problem at the field existence of checking meter at present, has designed a kind of distant place data collection station that directly by GPRS network copying data is sent to the central server of checking meter.

The technical scheme that the utility model adopted is: a kind of GPRS distant place data collection station, comprise CPU module, power module, RS485 communication module, GPRS communication module, the instrument terminal is for supporting the instrument of communication, each instrumented data is by communication and GPRS distant place data collection station swap data, and GPRS distant place data collection station moves public network by GPRS and is connected with the central server communication of checking meter.

Also comprise clock module, memory module, remote signalling/distant arteries and veins acquisition module, telemetry-acquisition module, remote control output module.

The CPU module is data, information processing control center, other module of management and running; Clock module provides the hardware calendar clock of terminal operating and software from programming clock; Memory module storage terminal every is provided with parameter and copies and accepts the instrumented data of returning; Power module is responsible for the terminal operating power supply; The RS485 module realizes and the instrument communication, copies and accepts the instrumented data that needs; The GPRS module sends to the central server of checking meter with the data of copying and accepting; Remote signalling/distant arteries and veins acquisition module, telemetry-acquisition module, remote control output module are installed on terminal and are used for the function expansion.

The utility model compared with prior art mainly contains following some positive effect:

(1) application broadness, the gauging table in fields such as water, electricity, heat, gas all can be copied and get, and especially can be widely used in the remote meter reading field of power industry;

(2) terminal directly sends to meter reading data on the central server of checking meter by GPRS network, no longer passes through the concentrator transfer, and simplified structure reduces the communication apparatus input cost, and the multi-point and wide-ranging occasion of checking meter of suitable instrument distribution;

(3) press flow charging, this is the another big feature of the GPRS communication of China Mobile, and it makes the operation cost of data transmission very cheap;

(4) the terminal installation is simple, convenient, as long as the place that has the GPRS signal to cover just can directly be installed, has removed the wiring of wired mode and the base station construction of wireless mode from;

(5) terminal has extendible remote signalling, remote measurement, distant arteries and veins, remote control port, and functional diversities can customize according to the actual requirements.

Fig. 2 is the utility model functional block diagram.

Among the figure: 1 is instrument, and 2 are communication, and 3 is GPRS distant place data collection station, and 4 for GPRS moves public network, and 5 are the central server of checking meter.

Embodiment:

Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing.

A kind of GPRS distant place data collection station, comprise CPU module, power module, RS485 communication module, GPRS communication module, the instrument terminal is for supporting the instrument 1 of communication 2, each instrument 1 data is by communication 2 and GPRS distant place data collection station 3 swap datas, and GPRS distant place data collection station 3 moves public network 4 by GPRS and is connected with central server 5 communications of checking meter.

The CPU module is data, information processing control center, other module of management and running; Clock module provides the hardware calendar clock of terminal operating and software from programming clock; Memory module storage terminal every is provided with parameter and copies and accepts instrument 1 data of returning; Power module is responsible for the terminal operating power supply; The RS485 module realizes and instrument 1 communication, copies and accepts instrument 1 data that need; The GPRS module sends to the central server 5 of checking meter with the data of copying and accepting; Remote signalling/distant arteries and veins acquisition module, telemetry-acquisition module, remote control output module are installed on terminal and are used for the function expansion.
