Today I will introduce to you a national invention authorized patent-a new type of water meter control system. The patent was applied by Tianjin Chuangzhan Tongcheng Technology Development Co., Ltd., and was authorized to be announced on April 24, 2018.
Description of contentThe invention belongs to the field of water meter design, and particularly relates to a new type of water meter control system.
Background of the inventionIn life, the detection of water consumption of residents is done through water meters. In order to reduce manual water consumption, smart water meters have become popular. The water meters are completed by setting water consumption in advance. The shortcomings of this water meter require users to frequently check water consumption. Its water consumption and remaining water volume are monitored in real time.
Summary of the inventionIn view of the existing problems, the present invention provides a new water meter control system to solve the problem that the water consumption of the existing water meters cannot be monitored in real time.
The schematic diagram of the present invention
In order to achieve the purpose of real-time monitoring of water volume, the technical solution adopted by the present invention is: a new type of water meter control system, including a water meter, a flow monitor, a control valve and a control box, the flow monitor is set on the water meter inlet pipe, the control valve It is installed on the water outlet pipe of the water meter; the water meter includes the water meter wireless module and the water meter MCU set inside, the water meter wireless module and the water meter MCU are electrically connected; the valve stem of the control valve is fixedly connected to the motor, and the motor is provided with the motor MCU; the control box There is a controller CPU inside; the flow monitor, water meter MCU, and motor MCU are electrically connected to the controller CPU respectively, and the water meter wireless module is wirelessly connected with a display device.
The display device shown is a smartphone. The connection between the water meter wireless module and the display device is a Bluetooth connection. The control valve is a ball valve. The flow monitor and the controller CPU, the water meter MCU and the controller CPU, and the motor MCU and the controller CPU are connected through UART wired serial communication.
Compared with the prior art, a novel water meter control system of the present invention has the following advantages: In a novel water meter control system of the present invention, the water meter wireless module and its wireless connection with a display device are implemented to detect the user's water consumption, and at the same time through the controller CPU Collect the value of the flow monitor and compare it with the set value of the water meter. Through the data comparison, the controller CPU controls the motor MCU, and then controls the motor spindle action, thereby controlling the opening or closing of the control valve, thereby controlling the user and the external The water source is connected or disconnected.
