Abstract

The utility model relates to an intelligent water meter capable of copying and reading prepayment in a wireless mode, which comprises a controller, wherein the controller is composed of a monolithic computer and is provided with a card reading circuit. The utility model is characterized in that a wireless signal receiving and transmitting device comprises one group of wireless signal transmitting and receiving modules which are installed in a hand-held set which has the function of a transcriber, and the other group of copying wireless signal receiving and transmitting modules which are arranged in the controller and are connected with a communication interface of the monolithic computer used as a control unit. When the utility model is used, the water supply management department can implement directly and comprehensively monitoring to the intelligent prepayment water meter which is installed indoors through the hand-held set outdoors so as to know the operational condition of the intelligent prepayment water meter. The utility model enhances management level and management quality of water supply, enhances work efficiency, and reduces labour intensity.

Description

Can wireless copy reading prepayment intelligent water meter

Technical field:

The utility model relates to water meter.A kind of prepayment intelligent water meter of more specifically saying so.

Background technology:

The cold-water meter that tradition is used has only function of measuring, can not carry out flow control, need be checked meter to the doorstep from door to door by water supply department during charge, then, provides the premium notice list, is paid the fees to appointment charge place by the user.This just water formerly, pay the fees after way to manage, make quite a few water rate receive not come up, manage extremely difficult.

Along with development of electronic technology, IC-card intelligence water meter has solved this difficult problem.This intellectual water meter has controller and control water valve, the user must hold purchase water after normal water.This control mode had both avoided water supply department to register one's residence checking meter difficult problem, had solved the problem of difficult charge again.But in a single day intellectual water meter packs in the user family, and water supply department just is difficult to monitoring to the operating position of water meter, and can't add up the user and work as water consumption per month.Water meter breaks down, even loses the pre-payment control function and all can't learn.Understand water meter ruuning situation and add up each user and work as water consumption per month, just must visit in every month to check, like this, not only water supply department work difficulty increase, and greatly hindered applying of prepayment intelligent water meter.

Summary of the invention:

Technical problem to be solved in the utility model is to avoid above-mentioned weak point of the prior art, provide a kind of can wireless copy reading prepayment intelligent water meter.So that administrative authority can directly implement overall monitor to the operating position and the water consumption of the indoor water meter of user out of doors.

The technical scheme that the utility model technical solution problem is adopted is:

The utility model comprises the controller with Card Reader circuit that is made of single-chip microcomputer.

Design feature of the present utility model is that wireless signal transceiver is set, comprise being installed in one group of wireless signal transmission, the receiver module that has in the hand-held set of making a copy of the instrument function, and another group is arranged in the controller, wireless signal receives, transmitter module with making a copy of of linking of microcontroller communication mouth as control module.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

Implement the utility model, water supply administrative authority can directly implement overall monitor to being installed in indoor prepayment intelligent water meter out of doors by hand-held set, understands water meter ruuning situation.Greatly improved water supply management level and management matter reason, increased work efficiency and reduce labor intensity.

Fig. 1 is the utility model structured flowchart.

Fig. 2 is the utility model circuit theory diagrams.

Embodiment:

Referring to Fig. 1, in the present embodiment, the controller that constitutes by single-chip microcomputer with Card Reader circuit, wireless signal transceiver is set, comprise being installed in one group of wireless signal transmission, the receiver module that has in the hand-held set of making a copy of the instrument function, and another group is arranged in the controller, wireless signal receives, transmitter module with making a copy of of linking of microcontroller communication mouth as control module.

During normal water supply, wireless receiving, transmitter module in the controller are in dormant state.In the time of need making a copy of, send one group of signal that comprises identification code and action code by hand-held set to the table internal controller, the radio receiving transmitting module received signal of controller send MCU to recognize by communication port identification code and action code.MCU is in advance with after confirming, the relevant information of the water meter internal memory that needs are sent is delivered to transmitter module by communication port, and carries out the emission of wireless signal on the control transceiver module.After hand-held set is received signal, related data is wherein handled, demonstrated the ruuning situation of intellectual water meter.For example, when water consumption per month, surplus water, last water time, valve state etc.And unusual water meter is carried out emphasis point out.

Hand-held set also can directly be transferred to the prepaid computer management system with relevant information data by interface, to the information data processing of classifying, to may pointing out by in-problem water meter, and finishes the monthly magazine etc. of water consumption by management system.

Referring to Fig. 2, in concrete the enforcement, wireless receiving, transmitter module adopt UHF radio transmitting and receiving chip NRF401, this chip is accepted the state control signal of single-chip microcomputer P1.2 with its 19th pin, accept the economize on electricity dormant control signal of single-chip microcomputer P1.1 port with its 18th pin, to microcontroller communication mouth S1, receive emission data with its 10th pin output data, and receive from the transmission frequency of single-chip microcomputer P1.3 port with its 12nd pin and to select signal from microcontroller communication mouth S0 with its 9th pin.

It is initial to power on, and the 19th pin of chip NRF401 is subjected to single-chip microcomputer transmitting-receiving control, and whole transmission circuit is in accepting state.In a period of time, fail to receive useful signal, then single-chip microcomputer electricity-saving control mouthful control transceiving chip the 18th pin enters the economize on electricity dormant state.After transmission circuit receives a series of data that hand-held set launches, deliver to microcontroller communication mouth S1 by the output of the 10th pin, after the process single-chip microcomputer is confirmed as valid data, single-chip microcomputer is then delivered to transceiving chip the 9th pin by the data that communication port S0 will need to launch, and selects the transmission frequency of regulation that data transmission is gone out by the 12nd pin of single-chip microcomputer channel control mouthful P1.3 control chip NRF401 simultaneously.Hand-held set is analyzed after receiving signal, demonstrate the present residing state of required data and water meter, after emission finishes, the controlled accepting state that enters of the 19th pin of chip NRF401, a period of time is interior as failing to receive new instruction, then single-chip microcomputer electricity-saving control mouthful control transceiving chip the 18th pin makes whole transmission circuit reenter dormant state.
