Description
Technical field
The utility model belongs to a kind of level flow measuring equipment device, relates in particular to a kind of open canal water level flow mensuring instrument capable of radio operatied.
Background technology
Level flow measuring equipment of open channel mainly contains four kinds at present: 1, being is principle with the ultrasound wave, measures water level earlier, and then carries out flow rate conversion.This method is subjected to such environmental effects such as temperature, air pressure and air quality big, and its precision is relatively poor.2, be to adopt stream drive impeller and linkage counter to constitute, utilize the close fit of flow and product specification to carry out level measuring.This method is not easy to the mutual conversion between the range, and floating thing also can have a strong impact on measurement effect in the canal.3, be the pressure reduction that utilizes the water level height that the water channel bottom is produced, thereby realize the measurement of flow.This kind method (as reservoir: tens meters) effect when wide range is better, and the journey time error is bigger in a small amount.Though 4, level flow measuring equipment of open channel has overcome the shortcoming on above-mentioned three kinds of measuring instrument principles, will dismantle protecting crust in data acquisition and parameter setting up procedure, is not easy to field work.
In the open open channel in the irrigated area of water conservancy and association area, particularly in the measuring process of trunk canal, branch canal low discharge, open canal water level flow mensuring instrument capable of radio operatied does not have this type of special measurement instrument through inquiry.
Summary of the invention
The level flow measuring equipment of open channel device that the utility model provides a kind of and convenient open-air used, can realize by radio operation.

Sensor body comprises sensor outer housing and the panel that is fixed on the sensor outer housing front, panel is made up of circuit board, electrode slice and insulation course, be attached with the electrode slice that shape is identical, area equates, equidistantly arranges on the circuit board, cover insulation course on the electrode slice, irritating between sensor outer housing and the panel has fluid sealant.
The external pole plate of charger is equipped with in the electrical box upper surface.Circuit board, battery case are housed in the electrical box, are fixed with LCDs, singlechip chip, memory circuitry, real time clock circuit, printed antenna, charger control circuit, radio transmitting and receiving chip, reset button, relay indicating light, malfunction indicator lamp on the circuit board.
Aforesaid sensor body can be connected by many sensors, link to each other by joint between the adjacent sensors, fix by coupling bolt between the joint, also be fixed with connector on the joint, the upper end of sensor body links to each other with attachment screw with electrical box, end cap is equipped with in the lower end of sensor body, and irritating between sensor outer housing and the panel has fluid sealant.
Open canal water level flow mensuring instrument capable of radio operatied when work, with water in the tested canal as public pole plate.When the water in the canal did not flood a certain monomer electrode slice, this electrode slice was with very little as the formed capacitance of the water in the canal of public pole plate, and testing circuit detects less than water level information.When the water logging in the canal was less than this monomer electrode slice, owing to there is insulation course to make dielectric, the water in the canal and this electrode slice formed parallel plate capacitor, and its electric capacity will increase than the electric capacity before flooding, and this electric capacity can be detected.When measuring, testing circuit detects each electrode slice, testing result is sent into single-chip microcomputer with digital signal form, pass through after data computing, the storage, the liquor charging crystal display screen shows, LCDs can be set to show water level or flow, also can be set to show in an alternating manner water level and flow.The measuring accuracy of sensor body is only relevant with monomer electrode slice arrangement pitches and single-chip microcomputer handling procedure on sensor, and irrelevant with factors such as ambient temperature, humidity, pressure and sensor lengths.Internal rechargeable batteries provides electric flux for measuring instrument work, when electric weight is not enough by the LCDs information.When battery electric quantity was not enough, the external pole plate of charger that be equipped with connection electrical box upper surface and the metal shell of sensor can charge to battery by charger control circuit, and above-mentioned two electrodes have anti-short circuit and anti-reverse characteristics.
Can write down unloading and parameter setting operation with wireless mode to it with a hand-held supplementary instrument, and not need instrument is uncapped, also needn't use any wiring.The sealing and the soundness of instrument are improved, more convenient use, operation and open-air the use.
Advantage of the present utility model is as follows:
1. sensor body precision height, resolution reaches 2 millimeters, and measuring accuracy reaches 4 millimeters.
2. measure range continued access as required, measuring accuracy is not influenced by range.
3. be furnished with real-time clock, can write down real-time streamflow regime.
4. mass storage satisfies the storage of long-time bulk information.
5. can measure or record by water level or flow.
6. can be applicable in any channel during by level measuring.
7. can directly select for use the 36 kinds of grooves, the weir that meet the water conservancy standard to set during by flow measurement, water level is converted into flow by numbering.Also can select for use self-defined mode to carry out multistage water level-flow restrains (mark) fixed back and is converted into flow by water level.
8. operation need not be uncapped, the open-air use of being more convenient for.
9. can write down unloading and parameter setting by wireless mode.
10. be with charging road and rechargeable battery, long-term use does not need to change battery.
11. the external pole plate of charger has anti-short circuit and anti-reverse characteristics.
12. integral sealing, good waterproof performance.
