[Chinese instrument network meter patent] creative limit, instrumentation invention. Today we introduce a national patent for invention—an IC smart water meter. The patent was applied by Ningbo Jinquan Intelligent Water Meter Co., Ltd., and it was authorized to be announced on February 8, 2017.
Description of the Invention The utility model relates to the technical field of smart water meters, in particular to an intelligent water meter for IC cards.
Background of the Invention The smart meter of IC card is a smart meter developed on the basis of traditional water meter that can realize the opening and closing of water meter through prepayment. It has been widely promoted to the dormitories of universities, apartments and enterprises and institutions. . However, the existing smart meter of the IC card generally follows the integral structure of the traditional water meter. Therefore, the chip and the circuit module in the IC card can only be replaced when the circuit module is damaged. Therefore, the cost is high.
SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide an intelligent water meter for an IC card, which is easy to maintain, and does not need to be scrapped when the parts of the water meter are damaged, thereby saving costs.
The figure is a schematic diagram of the structure of an intelligent water meter for IC cards of the present invention The technical solution adopted by the utility model is: providing an intelligent water meter for an IC card, which includes a base watch whose both ends are connected with an inlet end and an outlet end of a water pipe. The base watch is provided with a first housing containing a measuring component. The utility model is used for detecting the water flow in a base watch, which is characterized in that a detachable second housing is arranged above the first housing, a chip mounting cavity is arranged in the second housing, and the chip mounting cavity is slid A chip mounting substrate is matched, an opening for inserting the chip mounting substrate into the chip mounting cavity is disposed on a sidewall of the second housing, and an end of the chip mounting substrate is slid when the chip mounting substrate is slid into the chip mounting cavity to an extreme position The opening is sealed, and an electronic display screen is disposed on the second housing. An IC card sensing area is disposed on the sidewall of the first housing, and the IC card sensing area is connected to the chip signal in the second housing.
The second housing is provided with an observation port, and a double transparent glass is embedded in the observation port, which is used for directly observing the degree value of the code disk display in the detection unit. The double-layer transparent glass and the inner wall of the second housing form a perimeter. In the vacuum chamber, the vacuum chamber is filled with water-fillable filler.
The vacuum chamber incorporates a luminous body for illuminating the upper value of the dial in a dark external environment. The luminous body is a ring structure, and an annular luminous body is attached to the inner wall of the vacuum chamber and fixed.
After adopting the above structure, the intelligent water meter of the IC card of the utility model has the following advantages compared with the prior art: Firstly, the maintenance of the chip can be completed without the disassembly of the housing of the water meter through the extraction of the chip mounting substrate. Convenient and quick, the sealing of the water meter housing is good, and secondly, when the base meter is damaged or needs to be replaced when the service life is reached, the electronic components in the second housing can be disassembled and used continuously, and secondly, when part of the electronic components in the second housing are When it is damaged, it can be directly replaced by the application of calibration to the original set value, thereby reducing the maintenance cost of the smart meter.
