Level sensor.
2. when flashboard is less than or equal to the gate water surface, measurement and control host computer collection level sensor data and lock level sensor number
According to, and fluidised form is judged according to its collection value, lock flow is calculated by correspondence formula；
When flashboard is higher than the gate water surface, lock level sensor is replaced to measure the gate cross-section of river, and root by gate level sensor
Judge fluidised form according to its collection value, lock flow is calculated by correspondence formula.
3. the data that can only have a collection in synchronization both the lock level sensor and gate level sensor are
Valid data, the numerical value of lock level sensor and gate level sensor is compared, and the small person of numerical value is valid data, using this
Valid data pass through correspondence formula and calculate lock flow.
The correspondence formula, is known in the art public computing formula, and lock flow is calculated by velocity_area method.Lock
Door amount water is, by measuring the gate cross-section of river and channel water level, and judge fluidised form according to its collection value, by correspondingly formula meter
Calculate lock flow.But, in actual applications, flashboard is frequently above gate water level, when flashboard bottom is along higher than the water surface, with flashboard
The lock level sensor for matching just cannot effectively measure the real cross-section of river, also cannot just measure real lockage stream
Amount.In this case, because the width of gate is, it is known that the present invention measures the replacement of gate water level by gate level sensor
Lock position, also can be obtained by the cross-section of river of gate, also can just calculate real lock flow.Therefore, no matter flashboard is
It is no in water, with lock level sensor and the low person of gate level sensor measured value as Effective Numerical, calculated, you can obtain lock
The cross-section of river in road, also can just calculate real lock flow.
The mechanism for opening/closing of the flashboard, is known mechanism, such as headstock gear.
The gate, flashboard, lock level sensor, gate level sensor, measurement and control host computer, single chip circuit, communication interface,
Power supply and level sensor are visible known technologies on the market, can voluntarily assemble as needed or buy.
Beneficial effects of the present invention：Using the present invention, the lock flow of agricultural irrigation channel is in the case of flashboard standard-sized sheet
Can realize gate flow measuring, no matter flashboard just, no matter whether flashboard in water, can realize that lock flow is monitored so that
Increase application of the gate flow measuring system in vast plains region, because in the agricultural irrigation channel of plains region, irrigation season lock
Plate is often opened completely.
