[Chinese instrument network meter patent] creative limit, instrumentation invention. Today we introduced a national invention-issued patent - a remote meter reading system based on a pulsed water meter. The patent was applied by Tianjin Fanhua Qingyuan Water Technology Development Co., Ltd., and was authorized to be announced on June 13, 2017.
Content Description
The utility model belongs to the technical field of remote water meter application, and in particular relates to a remote meter reading system based on a pulse water meter.
Background of the invention
The remote water meter is composed of an ordinary mechanical water meter and an electronic collection and transmission module. The electronic collection and transmission module completes signal acquisition, data processing, storage and uploads the data to a repeater or a handheld meter reading device through a communication line. The body is designed in one piece, which can record and save the user's water consumption in real time or directly read the current cumulative number. Each meter has a unique code. When the smart meter receives the meter reading instruction, it can instantly upload the meter data to the management system. . Current smart remote water meters include many types, such as pulsed water meters, video cameras, etc. They are versatile and have different structures. However, in terms of performance and cost, pulsed water meters have been popularized by the industry, but pulsed water meters are currently used. Remote meter reading measures need to be further improved.
Summary of the Invention
The purpose of the utility model is to solve the above technical problems and provide a remote meter reading system based on pulse water meter which can greatly improve the accuracy of the flow meter.
To achieve the above objective, the present invention adopts the following technical solution: a remote meter reading system based on a pulse water meter, including a pulse water meter and a meter reading unit connected to the pulse water meter, the meter reading unit connecting users through a wireless network Terminal, the pulse water meter includes a first dry reed pipe and a second dry reed pipe for sending pulse signals by closing, and the first dry reed pipe and the second dry reed pipe are relatively parallel to the magnetic needle of the pulse water meter. On both sides, the meter reading unit includes a single-chip microcomputer and a wireless module connected to the single-chip microcomputer, a water card reader, a key module, and a display module; the first dry reed pipe, the second dry reed pipe and the single-chip microcomputer The pulse signal receiving end is connected.

The single-chip computer is connected with an alarm through an alarm circuit, and the alarm is a buzzer and/or a warning light. The microcontroller is connected to the battery module through a power supply circuit. The user terminal is a mobile phone.
The utility model comprises a pulse water meter and a meter reading unit connected with the pulse water meter. The meter reading unit is connected to the user terminal through a wireless network. The pulse water meter includes a first dry signal for sending a pulse signal through closing. The reed pipe and the second reed pipe, the first reed pipe and the second reed pipe are relatively disposed on both sides of the magnetic needle of the pulse water meter, and the meter reading unit includes a single chip microcomputer and a wireless module connected to the single chip microcomputer. a water card reader, a button module, and a display module; the first dry reed pipe and the second dry reed pipe are connected to the pulse signal receiving end of the single-chip microcomputer and can pass through the first dry reed pipe and the first part of the pulse water meter. Two reed switches send two signals to the single-chip microcomputer of the meter reading unit, and the single-chip computer counts according to two signals to improve the accuracy of the counting, and can send water consumption information or data to the user terminal through the meter reading unit, so that the user can Keep abreast of your water use, and recharge or pay in time.
