There is no limit to creativity, and instrumentation is invented. In view of the above situation, in order to overcome the shortcomings of the existing technology, today [instrumental invention] introduces a utility model patented invention authorized by the state—a wireless remote water meter.
The water meter was invented by Hunan Sanyi Science and Technology Co., Ltd. and was granted a utility model patent announcement on July 30, 2014. It includes a water meter body, a controller, a flow sensor, a micro power wireless communication module, a backup battery, a water meter body internal installation controller, a controller connection flow sensor, a micro power wireless communication module, a backup battery, and a water control valve The controller includes a single-chip microcomputer and peripheral circuits, an RF radio module and an alarm circuit. The single-chip microcomputer connects an RF radio module and an alarm circuit. The controller controls the micro-power wireless communication module to use a mobile network to send data, and the controller controls the water valve to open and close. The utility model has a passive wireless remote water meter which can save electricity, has simple structure, low cost, simple operation, convenient maintenance, low power consumption, stable data transmission, water valve control and alarm.
The technical problem to be solved by the invention is to overcome the above-mentioned defects in the prior art and provide a passive structure that is simple in structure, low in cost, simple in operation, convenient in maintenance, low in power consumption, stable in data transmission, capable of controlling a water valve, and capable of alarming. Wireless remote water meter.
The technical solution adopted by the invention to solve the technical problems is: a wireless remote water meter including a water meter body, a controller, a flow sensor, a micro power wireless communication module, a backup battery, a water meter body internal installation controller, and a controller connection The flow sensor, the micro-power wireless communication module, and the backup battery are characterized in that they also include a water control valve, the controller includes a single-chip microcomputer and a peripheral circuit, an RF radio module and an alarm circuit, the single-chip microcomputer connects an RF radio module and an alarm circuit, and the controller controls micro The power consumption wireless communication module uses the mobile network to send data, and the controller controls the water control valve to open and close.
Further, the water control valve adopts an electric floating ball valve, which has reliable operation and low pressure loss.
Further, the alarm circuit is composed of a patch transistor and a micro-buzzer.
Further, the backup battery uses a large-capacity lithium ion polymer backup battery of 2000 mA or more.
The working principle is: the external power supply is used for power supply. In normal use, only the flow sensor works, the controller and the micro power wireless communication module are in the standby state, waiting for the wireless command or RF card; when the wireless meter reading instruction is received, it is activated. The controller and the micro power wireless communication module work to read the flow sensor count value; when receiving the wireless control water valve instruction, the water control valve is closed or opened; when an RF radio frequency card is detected, the controller and the micro power consumption are activated. The wireless communication module works. The RF module reads and writes the RF card, and the backup battery provides backup power.
Compared with the prior art, the utility model has the advantages of simple structure, simple operation, power saving, low cost, convenient maintenance, low power consumption, stable data transmission, and capable of controlling the water valve and the passive wireless remote water meter capable of alarming.

[Invention of Instrumentation] Wireless Remote Water Meter
The application of wireless transmission technology makes life convenient and time-saving; current water meters are divided into mechanical and electronic types. Mechanical water meters have been familiar and used by the people in the past decades. The development of electronic technology, water meters are not Is a single form of structure, not a single function, the improvement of living standards, people are more concerned about the ease and convenience of services; the popularity of remote meter reading meter, making remote meter reading becomes a reality; while the meter is still using manual meter reading, time-consuming Effortlessly, the rotating plate is easily adsorbed by other objects to stop metering; existing electronic water meters are self-propelled, long-distance transmission power consumption, spare battery supply time is short, it is not convenient for later maintenance, data transmission is unstable, and the water valve cannot be controlled. How to make use of existing communication technologies and network platforms to complete meter readings more easily and become R&D personnel R&D. Specific instructions:
