3, the scene that overcomes check meter difficulty problem, reduce the labor intensity of staff, save manpower and materials.

4, improve the accurate of meter reading data and promptness.

5, by after unified for data arrangement, it is simple to Running-water Company carries out pipeline analysis and managing power consumption.

Accompanying drawing explanation

With detailed description of the invention, the application is described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is the modular structure schematic diagram of a kind of GPRS remote transmission water meter collector of the application.

Detailed description of the invention

Those skilled in the art understands for convenience, and below in conjunction with embodiment, the present invention will be further described. Embodiment is only the illustration to this invention, is not limitation of the invention, does not makees the step illustrated in embodiment It is all prior art, is not described in detail at this.

Embodiment one

A kind of GPRS remote transmission water meter collector as shown in Figure 1, connects including foreign current power supply function module, internal dc source Mouth, low-power dissipation power supply process functional module, external power source output interface, MCU(master controller Master Control Unit) merit Can module, GPRS(general packet radio service technology General Packet Radio Service) communication function module, logical Letter interface 1, communication interface 2, user interface, pulse collection interface 1, pulse collection interface 2.

It is MCU that external dc power functional module, internal dc source interface process functional module by low-power dissipation power supply Functional module and GPRS communication function module for power supply, external power source output interface and low-power dissipation power supply process functional module and are connected, Circuit outside harvester can be powered.

The GPRS remote transmission water meter collector of the application has three kinds of powering modes: one is to be supplied by external dc power functional module Electricity, i.e. by outside mains-supplied, is suitable for the situation having power supply around water meter；Two is to be powered by internal dc source interface, i.e. by Mounted internal dry cell power supply, when being suitable for not having suitable external power source around water meter；Three is mixed model, when outside is straight When stream power supply function module power-down stops supplying, it is rapidly switched to internal dc source interface by power supply switch circuit and powers, when outward Can be switched to again mains-supplied when portion's DC source functional module restores electricity, this pattern can ensure that terminal long-time stable Run, and do not affected by mains failure.

GPRS communication module, in dialing and data transmission procedure, has the requirement (3.9V, 2A) that comparison is special to power supply. The heavy current impact of moment makes the supplying cell of the product of a lot of low-power consumption cannot meet its technology requirement.The collection of the application Device mainboard has carried out thorough optimization to GPRS prime function of supplying power module, changes conventional power supply plan so that the power supply of battery Minimum 3.0V still can meet the requirement of communication.Extend the service life of battery.Then the blood pressure lowering of scheme in the past exports improvement Scheme uses boosting output, through DC/DC(Direct Current/ Direct Current) transducer boosting, the confession of battery Piezoelectric voltage scope is exaggerated, and is more suitable for the operating of GPRS communication module.

Field apparatus is that common water meter copies and accepts frequency requirement not quite, and battery can be used to power.For copy and accept frequency big and The user that water consumption is big can use external power source to power, real-time data transmission, zero-lag.Under battery electric power thus supplied, harvester Each transmission time can control within 1 minute, quiescent dissipation 11uA, the theoretical use time of battery > 5 years.

Communication interface 1 is RS232 port, and communication interface 2 is RS485 port.When water meter is intellectual water meter, GPRS Remote transmission water meter collector can be connected with intellectual water meter by communication interface 1 or communication interface 2, simultaneously communication interface 1 or communication Interface 2 can also connect with user computer, is transferred to use by the data of water meter collected by communication interface 1 or communication interface 2 On the computer of family.

Pulse collection interface 1 is direct impulse acquisition interface, and pulse collection interface 2 is reverse impulse acquisition interface, works as water When table is pulse water meter, GPRS remote transmission water meter collector can pass through pulse collection interface 1 or pulse collection interface 2 with corresponding Water meter is connected.

Communication interface variation, direct impulse, reverse impulse, RS232 port, RS485 port etc. are adapted to mesh Front market all terminals table meter product.

Arranging harvester for the convenience of the user, harvester is additionally provided with user interface, and user can be connect by user operation Mouth manually wakes up harvester up, it is also possible to arranges transmission means and is timing transmission, interval transmission or manually wakes up transmission up.

MCU functional module is that data process relevant core processing module, the ammeter data that MCU functional module will collect Passed on remote terminal by GPRS communication function module.Staff directly just can receive water at a distance in office Table data, greatly reduce because the manpower and materials spent by manual metering, also improve the accuracy of meter reading data.

Design and the manufacture of the GPRS remote transmission water meter collector of the application use in the industry in strict accordance with technical grade standard, PCB Top FR-4A level (military) sheet material.Components and parts used are satisfied by the temperature range of-40 DEG C to+80 DEG C.Degree of protection is IP65.

In city, the GPRS remote transmission water meter collector being respectively mounted the application at water meter is set at large diameter pipeline, from the beginning Waters corporation can carry out pipeline analysis and managing power consumption by the data that transmission receives, it is possible to omnibearing faster easily That grasps city uses regimen condition, simultaneously according to data of water meter, can find whether water meter stopwatch, bad table occurs in time, convenient real-time Monitor whole water supply pipe the most properly functioning.

The above is embodiments herein.The application is not limited to above-mentioned embodiment, and anyone should learn The structure change made under the enlightenment of the application, every have same or like technical scheme with the application, each falls within this Within the protection domain of application.
