Problems solved by technology

[0003] At present, in the prior art, the counting method of the water meter is to install a magnet on the pointer of the water meter, and then install a sensor on the casing for induction counting. One-piece molding, the disadvantage of this is that the sensor is easy to cover the dial and affect the reading. On the other hand, the installation of the sensor is difficult, and the assembly time of the worker is longer

Embodiment Construction

[0013] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. Such as Figure 1-Figure 5 As shown, a smart water meter includes a water meter body 1, a water meter inner shell 2, and a water meter outer shell 3. The water meter inner shell is placed inside the water meter outer shell and fixed on the water meter body together. The water meter inner shell The upper part is provided with a mounting groove 4, and the lower part of the inner casing of the water meter is used for installing a motor 5. The side of the mounting groove close to the dial is provided with a sensor fixing groove 6, and the sensor is fixed in the sensor fixing groove. The supporting columns 7 are installed at the four included corners, and the circuit board 8 and the display screen 9 are installed on the supporting columns, so that the structure is divided into two layers, making the structure m...

Abstract

The invention relates to the field of water meter devices, in particular to a smart water meter. The smart water meter comprises a water meter body, a water meter inner shell and a water meter outer shell. The water meter inner shell is arranged in the water meter outer shell, and the water meter inner shell and the water meter outer shell are commonly fixed to the water meter body. An installinggroove is formed in the upper portion of the water meter inner shell, the lower portion of the water meter inner shell is used for installation of a motor, a sensor fixing groove is formed in the side, close to a meter disc, of the installing groove, and a sensor is fixed into the sensor fixing groove. Supporting columns are installed in the four corners of the installing groove, and a circuit board and a display screen are installed on the supporting columns. The water meter is compact in structure and convenient to assemble, the sensor is assembled on the water meter inner shell, the water meter inner shell and the water meter outer shell can be independently assembled, the water meter inner shell and the water meter outer shell are installed on the water meter body after being assembled, assembly by a worker is very convenient, and the sensor is placed on the side face of the meter disc, so that read numbers are not shielded.

Description

technical field [0001] The invention relates to the field of water meter devices, in particular to an intelligent water meter. Background technique [0002] With the continuous promotion of smart card technology, contactless smart cards have been widely used in small payment applications such as public transportation, taxis, and oil due to their convenience and safety. In the intelligent water fee charging application where the water meter and the smart card reader are integrated, the user deposits a certain amount of money in the smart card in advance, and the user only needs to use the smart card when paying. According to the data of water resource use, the corresponding amount is deducted from the money stored in the smart card, and the payment process of the water fee is completed. [0003] At present, in the prior art, the counting method of the water meter is to install a magnet on the pointer of the water meter, and then install a sensor on the casing for induction c...
