Embodiment

See also shown in Figure 1, the utility model includes cavity 6, electrically operated valve 5, flowmeter 4, watermeter shell 3, control module 1 and LCD S1, wherein, flowmeter 4 is installed in the cavity 6, flow through the fluid flow of cavity 6 with measurement, electrically operated valve 5 is located in the cavity 6, to control the logical of cavity 6 and to close, LCD S1 is located at watermeter shell 3 surfaces, to show various data, control module 1 and electrically operated valve 5, flowmeter 4 is sealed in the watermeter shell 3, flowmeter 4 and control module 1 line are to input to flow signal control module 1, electrically operated valve 5 and control module 1 line, 1 control of controlled unit, LCD S1 and control module 1 line.See also Fig. 2 and shown in Figure 3, wherein, control module 1 includes PIC16F84 microprocessor U4, wireless remote transmission module J 1, clock circuit 11, under-voltage testing circuit 12, valve controling circuit 13 and battery 14, wherein, wireless remote transmission module J 1 is connected to 2 of microprocessor U4,3, on 11 pins, the pin 1 of microprocessor U4,18 are connected with LCD S1, flowmeter 4 is connected on 6 pins of microprocessor U4,5 of X1203 integrated package U5 in the clock circuit 11,12 of 6 pins and microprocessor U4,17 pins connect, valve controling circuit 13 and 9 of microprocessor U4,10 pins connect, this valve controling circuit 13 is connected with electrically operated valve 5, under-voltage testing circuit 12 mainly is by 2 TLV2211 comparer U1, U2 and TPS76033 regulator block U3 and relevant components and parts are formed, 7 of the U4 of this under-voltage testing circuit 12 and microprocessor, 8,13 pins join; Clock circuit 11 is made up of X1203 integrated package U5 and crystal oscillating circuit.

Principle of work of the present utility model and process are as follows:

After the user buys the water word, data are passed through wireless remote transmission module J 1 input information of the meter-copy device of property department to water meter, be stored in after the identification among the microprocessor U4, the meter-copy device of property department can send personal code work to the user, purchases the water yield, water rate and control information, and accept information such as this user's water information that transmits from user's water meter and water meter duty, detect so that effectively carry out water, in time carry out after sale service; Flowmeter 4 is passed to microprocessor U4 with flow number, handles the back and shows by LCD S1; Under-voltage testing circuit 12 detects the voltage of battery 14 in real time, when the capacity of battery 14 is not enough, import under-voltage information into microprocessor U4, microprocessor is controlled LCD S1 on the one hand, display message " is changed battery " and is informed the user, on the other hand with information stores in microprocessor U4, by wireless remote transmission module J 1 under-voltage information is notified to administration departments by meter-copy device.The time of the clock circuit 11 real time record waters that are connected with microprocessor U4, when user's water consumption overfulfiled the quota, water meter can be realized the function that excess is partly raised the price, i.e. staged metering water price.

As shown in Figure 4, the concrete workflow of remote transmitting water meter is as follows:

At first open an account and clock, after water meter detects under-voltage, if under-voltage then report to the police, if under-voltage then detect meter-copy device whether calling is arranged not, if calling arranged then carry out information interchange with property, if do not call out then detect whether flow signal is arranged, if flow signal is arranged then detain water treatment, if do not have flow signal then be returned to beginning, detect water consumption after the button water treatment and whether surpass a month quota, if surpass, then charge, if do not surpass with the metering method that exceeds the quata, then take with normal metering method note, at this moment, LCD S1 demonstration residue is purchased the status information of the water yield and water meter, if the last water yield of purchasing is less than zero, then report to the police, continue feedwater,, reach 10m such as owing the water yield when owing the water yield when reaching some ³, then close valve and cut off the water supply, if be not less than zero, then continuing opens an account clock feedwater, so repetition.

Radio remote transmitting water meter of the present utility model adopts the wireless remote transmission module to mediate, and realizes the information interchange between user and the charge department, needn't assist and establish cable, can save the engineering spending, meter reader can be checked meter at any time, in real time monitoring, prevent stolen water, can in time change battery, make things convenient for after sale service.Introduce clock circuit in the circuit design, can realize by time staged metering water price, effectively conserve water resource.
