Today, I will introduce a national invention authorized patent-a smart water meter with water quality detection function. The patent was applied for by Chengdu Sanyu Instrument Technology Development Co., Ltd., and the authorization was announced on February 8, 2017.
Content descriptionThe utility model relates to the technical field of water meters, in particular to an intelligent water meter with a water quality detection function.
Background of the inventionSmart water meter is a new type of water meter that uses modern microelectronics technology, modern sensor technology, and smart IC card technology to measure water consumption, transmit water data and settle transactions. Compared with traditional water meters that generally only have the functions of flow collection and mechanical pointer display of water consumption, this is a great improvement. In addition to recording and electronically displaying the water consumption, the smart water meter can also control the water consumption according to the agreement, and automatically complete the calculation of the water fee of the step water price. At the same time, it can perform the function of water data storage.
However, when the existing smart water meter is in use, because there is no regular monitoring function, the water flow in the water meter is continuously monitored in real time, which consumes a lot of electric energy. For the smart water meter with a built-in power supply, it needs to be replaced frequently. Batteries bring unchanged to users. For this reason, we have proposed a smart water meter.
Summary of the inventionThe purpose of the present utility model is to provide an intelligent water meter with water quality detection function to solve the problem of high energy consumption of traditional water meters proposed in the background art.
In order to achieve the above objective, the present utility model provides the following technical solutions: an intelligent water meter with water quality detection function, including a water meter housing, the left and right sides of the water meter housing are symmetrically installed with connecting water pipes, and the top and bottom of the connecting water pipe on the left side are symmetrical There is a mounting slot, the outer wall of the connecting water pipe on the left side is provided with an embedded slot, the surface of the water meter housing is provided with an LCD display screen, the LCD display screen is connected to a micro processor for electrical input, and the micro processor is electrically connected to each other. The data exchange unit, the clock unit and the storage module are connected in two ways. The storage module is electrically connected to the user input query unit, and the micro-processor is electrically connected to the valve control unit and the alarm prompt circuit. The alarm prompt circuit is electrically connected to the valve control unit and the alarm prompt circuit. The electrical output is connected to a buzzer alarm, the micro processor is electrically connected to the power supply circuit, the turbidity sensor and the metering sensor, and the turbidity sensor and the metering sensor are both electrically connected to the timing module.
Preferably, the left and right ends of the connecting water pipe are provided with detachable bayonet, and the end of the detachable bayonet is covered with a sealing ring. The embedding groove is located on the vertical line between the two sets of installation grooves, and the position of the groove of the embedding groove is a U-shaped opening groove. An external communication interface is provided inside the data exchange unit. The storage module is provided with multi-group hierarchical storage units, and a conversion interface is provided between the two groups of hierarchical storage units.
Compared with the prior art, the beneficial effect of the utility model is: the sensor adopts timing control, the power consumption is very low, and it can fully meet the needs of the water meter using the built-in power supply, and the slot module is installed at the meter end of the water meter. After improvement, multiple modes of using one module for multiple meters and one module for single meters can be realized. The turbidity and flow rate of the water quality in the water pipe can be monitored. When the water quality, flow rate and valve are abnormal, the buzzer can alarm in time. Remind users to pay attention.
