[Chinese instrument network meter patent] creative limit, instrumentation invention. Today, we introduce a national patent for invention invention - a smart card control water meter. The patent was applied for by Zhengzhou Leyuan Electronic Technology Co., Ltd., and obtained the authorization announcement on January 9, 2018.
Content Description
The invention relates to the field of card application technology, in particular to a smart card control water meter.
Background of the invention
A water meter is an instrument used to measure the flow of water. Most of the cumulative flow measurement of water. It is generally divided into two types: volume type water meter and speed type water meter. With the development of society and economy, traditional water meters have been replaced by smart water meters, but there are still some problems in the use of smart water meters in the market. The existing smart water meter can only alert the water quantity and the function is too single. Therefore, a water meter needs to be designed to solve the above problems.
Summary of the Invention
The purpose of the present invention is to provide a smart card control water meter that overcomes the above-mentioned technical disadvantages and is easy to use through a smart card control.
The figure is a schematic structural view of the present invention
The technical solution adopted by the present invention to solve the technical problem is: a smart card control water meter including a housing, a card body slot, a water inlet pipe, and a dial; a card body slot is disposed on an edge of an upper surface of the housing; There is an inlet pipe, a dial is arranged on the upper part of the upper surface of the casing, a touch screen is arranged in the middle of the upper surface of the casing, a power switch is arranged on the middle edge of the upper surface of the casing, and an operation indicator is arranged on the central edge of the upper surface of the casing. A charging interface is arranged, a charging indicator is arranged on the side of the housing, a cover is arranged at the lower end of the housing, an alarm is arranged on the cover, and a water outlet pipe is arranged on the cover. In the above structure, the water meter has a pre-paid function, a stepped water price function, a hoarding quota function, a refund function, and an early warning function. The card body slot can insert a water and electricity card, and the alarm device can alarm in an abnormal situation, and the user can operate through the operation. Touch screen to achieve the above functions.
The card body slot is embedded in the edge of the upper surface of the shell, the water inlet pipe is fastened in the middle of the upper surface of the shell by screws, and the dial plate is embedded in the upper part of the upper surface of the shell. The touch screen is embedded in the middle of the upper surface of the shell, the power switch is embedded in the middle edge of the upper surface of the shell, and the working indicator is embedded in the middle edge of the upper surface of the shell. The charging interface is inlaid on the side of the housing, the charging indicator lamp is mounted on the side of the housing, and the cover is fastened to the lower end of the housing by screws. The alarm is connected to the cover by screws, and the outlet pipe is fastened to the cover by screws.
The invention has the beneficial effects that the structure of the invention is reasonable in design, convenient in use, complete in function and higher in intelligence, and worthy of being popularized and used.
