In the present embodiment, a diameter of 30mm of floating ball, the spacing between adjacent hall switched sensor are
10mm。
Hall switched sensor is all based on the work of Hall effect principle as linear Hall piece.Hall switch
There are two types of states, i.e. high level and low level for the output of formula sensor.Hall switched sensor model number is used herein as OH3144.
OH3144 hall switcheds sensor uses the magnetosensitive circuit of semiconductor integration technology manufacture, it is adjusted by voltage
Phase, Hall voltage generator, difference amplifier, Schmidt trigger and open collector the magnetosensitive of triode composition pass
Inductive circuit is as shown in Figure 1.When magnetic fields are when on Hall plate, according to Hall effect, Hall element output Hall voltage UH should
Voltage is sent into schmidt shaping circuit after amplifier amplifies, and when amplified UH voltages are more than threshold voltage Uth, applies
Close spy's circuit is overturn, and exports high level, transistor is connected；When field weakening, the electricity of Hall element output
UH very littles are pressed, when amplified UH voltages are less than threshold voltage Uth, Schmidt circuit is cut-off state by conducting state overturning,
It exports as low level, triode is caused to end.Since the Integrated electrode of hall switched sensor internal is opened a way, so during work
It must additional pull-up resistor.
In present embodiment, testing principle is：
The height of water level is judged using the position of the floating ball swum on water level, which is vertically placed to geothermal well
In, when the water level in geothermal well changes, corresponding floating ball also rises or falls therewith, thus triggers hall switched and passes
Sensor exports low level, due to the distance between hall switched sensor it is known that base position is it is known that pass through ARM microcontrollers
The level signal of acquisition process hall switched sensor output, you can learn the height of water level, can finally be shown by display module
Show current level height or water level information is transmitted to ground monitoring system.
In present embodiment, the top of water-level detecting device can be mounted on according to the communication distance of geothermal well in geothermal well
Portion, can also be close to ground.
According to level gauging principle it is found that the distance between Hall plate is smaller, then the resolution ratio of level gauging will be bigger；
Conversely, resolution ratio can be smaller, when hall switched working sensor, ARM microcontrollers are sentenced according to prior designed program
Which hall switched sensing of breaking is sensed.
In present embodiment, the diameter selection 30mm of floating ball, the spacing selection 10mm of hall switched sensing, circuit
Overall output is more stable, and when the basic face Hall plate in the center of floating ball, the Hall plate of face is sensed at this time, exports low electricity
Flat, the output of remaining Hall plate is high level, is understood according to theory experiment：When the center of floating ball is located among two Hall plates
When, and when Hall plate spacing is more than 18mm, adjacent at this time two Hall plates will not sense, and output is all for high level, when suddenly
When your piece is smaller than 15mm, adjacent at this time two Hall plates are sensed simultaneously, are exported as low level；When Hall plate spacing is small
When 4mm, continuous 3 or 4 Hall plates can all be sensed simultaneously, cause the unstable of output level.So present embodiment
Select 10mm.It can accurately detect the location information of floating ball.
In the present embodiment, balance water level open tubular column chamber is sensed using heat safe material, and in hall switched
The surface of device, which installs one, has water-proof function and the protective case of heatproof.
The present invention installs the pipeline of a high temperature-proof over long distances in geothermal well, is sensed in pipeline using hall switched
The effect of kicker magnet carrys out timing sensed water level information in device and floating ball, can realize the geothermal well water level detecting of long range, not need to
Periodically adjust its installation site；The information of detection directly by internal wire transmission to control section, and by detection device
Top be mounted on geothermal well interior energy realize with ground signal transmission position, can effectively solve the problem that in the prior art underground transmission
The problem of signal difference.
It is obvious to a person skilled in the art that the present invention is not limited to the details of above-mentioned exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
