Description

IC-card liquid crystal display automatic gauge water meter

The utility model belongs to a kind of self-measuring device.

At present, the even metering method that adopts stem-winder of device aspect water metering, its structure is installed water meter on water-filled pipe, advancing the no-load voltage ratio gear by water wheels and machinery ten in the water meter connects, water wheels are owing to the impulse force of current rotates, press 10: 1 no-load voltage ratio transmission of mechanical gear, this kind water meter structure is simple, and is easy to install, and reading is more directly perceived, but its weak point is to lack intelligent function, the statistics of need checking meter is from door to door brought very big inconvenience to management, on the other hand because physical construction, normal malfunctioning owing to stop up, cause very big difficulty to installation and maintenance.

For solving the deficiency of above mechanical water meter, the purpose of this utility model provides a kind of CI card liquid crystal display automatic gauge water meter, adopts circuit control, has intelligent function, and to reach the accurate automatic gauge of water, use and management is purpose easily.

The structure that the structural design of the utility model is achieved in that this metering water meter is made up of physical construction part and control circuit two parts, the mechanical part outside is a housing, both sides are the import and export of water, water sieve is equipped with in the inside at water inlet, the screen pack the inside is a movement main body, impeller is housed in the movement main body, the movement side is the movement water delivering orifice, it on the movement core upper cover, on the top of core upper cover pulse switch and pole plate are housed, switch connects with pole plate, pole plate and impeller are fixedly connected simultaneously, and the switch outside is added with the switch outer cover, and the opposite side of movement is equipped with automatic valve, the water inlet of valve is equipped with the valve screen pack, the outlet of valve is fixedlyed connected with water delivering orifice, and control circuit board and LCDs are equipped with for the table loam cake in the top of table above the loam cake, be the IC-card socket above the circuit, the top of socket is the compact lithium cell seal box; Central controller CPU is housed on control circuit board, and CPU output has the LCDs driving circuit, and driving circuit directly connects with display screen, and peripheral circuit has table pulsing circuit and reset circuit, and its output is joined with the CPU input end; In addition with the two-way IC-card interface circuit that is connected with of CPU, interface circuit and IC-card join, CPU output has valve driving circuit simultaneously, driving circuit connects valve, valve directly connects the water meter outlet, and valve joins with warning circuit simultaneously, and the CPU outside connects battery and directly powers, whole device is an integral body, can directly join with the tap water pipe line standard interface.

Advantage of the present utility model: simple in structure, easy to install, adopt IC-card to charge, charge accurately, convenient management, the circuit stable and reliable operation can extensively be promoted the use of.

The detailed structure of the utility model is provided by following examples and accompanying drawing.
