Background technique
In rural area, many place urbanite water consumptions cannot unify central water supply, hydraulic pressure very little, and majority is the mountain spring attracted self
Water needs that water is delivered in the water tower on roof by pump.Since water tower is placed in roof, people wants to know that water level just needs to climb to
Roof goes to see the position of water, quite inconvenient.So sometimes not having water (minimum water until the water in water tower is used up just discovery
Position), water cannot be replenished in time.Sometimes usually wait until that water overflows (peak level) and just found water tower again toward water tower conveying water
Through full.In this way, one brings inconvenience to life, two waste many water resources.Also often there is this in agricultural irrigation
Class problem.
To prevent the water of water storage device from overflowing, existing several technical solutions are as follows:
1. float-ball type valve-closing, the program only need to install the valve with floating ball additional in water storage device water outlet, float after water is full
Ball, which floats to certain position, will drive valve pass.
2. sensor detects, this scheme is to install water sensor additional in peak level and lowest water level to carry out the spy to water level
Survey, when water level reach highest or it is minimum when can trigger alarm or carry out linkage with pump to turning off or on pump.
1 disadvantage of above scheme: valve is small, and water outlet is small, has very big hindering factor for water pump, it is complete that water expires late gate
It closes, in the case where pump cannot cut off the power in time, pump is also just completely plugged, easily damage pump.
2 disadvantage of above scheme: can only know two limiting water levels of water storage device, increase number of sensors and increase equipment
Complexity, therefore the real time position of water cannot be grasped in real time, this has many inconvenience for agricultural production.

Fixed pulley at high water level；Float follows water level decreasing when water level decreasing, by rope band movable pulley to drive encoder just
To rotation, when water level rises, float is lifted by the buoyancy of water, and sinker descent tape movable pulley is to drive encoder to reversely rotate；
The encoder same direction rotates a circle the pulse that can send certain number to coding-decoding circuit, passes through encoding and decoding
Circuit carries out counting union and is converted into corresponding SEA LEVEL VARIATION and calculates current water level to pulse；The coding-decoding circuit handle
Current water level signal sends terminal to by communication interface.
In a preferred embodiment: the encoder same direction rotate a circle can send 24 subpulses to encoding and decoding electricity
Road.
In a preferred embodiment: the calculating process of the current water level is as follows:
Definition: water depth H, diameter of pulley D, pulley circumference L are then L=π D.
