Today I will introduce you to a national invention authorized patent-a smart water meter. The patent was applied by Tianjin Chuangzhan Tongcheng Technology Development Co., Ltd., and was authorized to be announced on May 8, 2018.
Description of contentThe invention belongs to the field of flow measurement, and particularly relates to an intelligent water meter.
Background of the inventionWith the development of smart meters, the automatic billing function of electric meters is gradually popularized, but due to the mechanical structure of water meters, it is still generally based on manual reading billing, which is not only inefficient, but also a waste of labor, sometimes users go out and forget to turn off the faucet Not only caused damage to the family, but also wasted water resources.
Summary of the inventionIn view of the existing problems, the present invention provides an intelligent water meter to solve the problem of manual reading, which is not only inefficient, but also wastes labor, and the user cannot check the status of the water meter in time.
Figure is a schematic diagram of the structure of the present invention
In order to achieve the above object, the technical solution adopted by the present invention is: an intelligent water meter is installed on a water pipe, and the water pipe is also installed with a static water tank, the intelligent water meter includes a microcontroller and a photoelectric direct reading device connected to the microcontroller, wireless data Communication device, water quality detector, LCD display screen, the signal output port of the photoelectric direct reading device is connected to the signal input port of the microcontroller, the signal output port of the water quality detector is connected to the signal input port of the microcontroller, and the signal output of the microcontroller The terminal is connected to the signal input terminal of the LCD screen, and the probe end of the water quality detector is embedded in the static water tank and fixed by a nut.
The static water tank is a hollow cylinder with a diameter larger than the diameter of the water pipe, and water outlet holes with the diameter of the water pipe are left at both ends. An IC card reading device is also installed on the surface of the smart water meter, and the signal output terminal of the IC card reading device is connected to the signal input terminal of the microcontroller. A solenoid valve is also installed inside the smart water meter, and the solenoid valve is connected with the microcontroller. The wireless data communication device is a WiFi communication device. The microcontroller performs data transmission with mobile phones and computers via wireless data communication devices. A relay is also connected between the microcontroller and the photoelectric direct reading device, and the microcontroller controls the relay by sending control signals.
Compared with the prior art, the smart water meter of the present invention has the following advantages: (1) The smart water meter of the present invention can log in to the client through a mobile phone or computer to check the usage and water quality of the water meter. If you forget to turn off the faucet when you go out, you can also remotely control the electromagnetic Valve, thereby closing the faucet and preventing water wastage. (2) The smart water meter of the present invention can help the water company to realize remote intelligent management of the water system, and the user can recharge the water by himself, which not only improves the efficiency of the water company, but also facilitates the user.
