Description
Technical field
The utility model relates to condensate tank of dehumidifier, particularly a kind of the water level measurement control system adopting light lotus root and field effect transistor.
Background technology
It is go to check water tank without the need to people to the capacity check of water in water tank that cistern water level detects.If what in water tank, the number of water opened that water tank just sees always arrives, that will be a very loaded down with trivial details thing with losing time, by the detection to cistern water level, testing result is presented on LCD, we can know the water level conditions in water tank intuitively, the situation to water level in water tank that more can control Intelligent Single-Chip Based controls, and such Based Intelligent Control will facilitate our daily life.
Have several to the detection of water level at present, electrode slice sensed water level, hydraulic pressure sensor sensed water level, dry-reed type water level detecting etc.Dry-reed type water level detecting adopts tongue tube to carry out water level detecting, principle buries tongue tube underground according to certain size requirement branch in a measuring stick, the float with permanent magnet of each tongue tube subsection setup ring-type, tongue tube is positioned at every section of top, and restriction float only moves up and down in this section, attract tongue tube action when buoyancy of water lifts float to permanent magnet during the top of segmentation.The float of tongue tube is when moving up and down, and its reliability is low, so method is not promoted.Adopt hydraulic pressure sensor sensed water level, pressure transducer is arranged on water tank bottom, determines water level by measuring hydraulic pressure.But can sensor be damaged during water tank water temperature over-high, thus require too high to water temperature, general little the method; Adopt electrode slice sensed water level, principle is the electric conductivity utilizing water, and electrode slice on an insulation rod, forms measuring stick according to certain dimensional requirement branch, comes in and goes out from tank top, when water touches electrode slice and conducting.As long as the problem of this circuit is the formation of incrustation scale, the detection impact on water level is larger.
Utility model content
The purpose of this utility model is to provide a kind of the water level measurement control system adopting light lotus root and field effect transistor.
The purpose of this utility model is achieved through the following channels: a kind of the water level measurement control system adopting light lotus root and field effect transistor, some wires that tail height is different are placed with in water tank, electric wire connects the input cathode of light lotus root, the input anode of light lotus root connects the 12V power supply of field effect transistor connection control, the output head anode of light lotus root meets VCC, the negative pole of output end of light lotus root receives the analog input I/O port of MCU, and described MCU is by driving relay water pump or solenoid valve; Described water tank ground wire.
As the further optimization of this programme, described tank top installs the patch bay of a wound wire.
As the further optimization of this programme, described electric wire afterbody is connected to the thing that heavily hangs down.
A kind of the water level measurement control system adopting light lotus root and field effect transistor of the utility model.System realizes can intelligentized control method entirely, when MCU reads the height of water level, by driving the peripheral hardware feed-tank that relay connects to add water or draining, going to observe control, use more convenient without the need to people.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model scheme of installation
In figure, water tank 1, electric wire 2, light lotus root 3, field effect transistor 4, power supply 5, VCC6, MCU7, patch bay 8, ground wire 9, heavily vertical thing 10.
Embodiment
As shown in Figure 1 and Figure 2, a kind of the water level measurement control system adopting light lotus root and field effect transistor of the utility model, it is the patch bay 8 installing a wound wire 2 at water tank 1 top, some wires 2 that tail height is different are placed with in water tank 1, the length of choose reasonable line, to detect the water level of differing heights, electric wire 2 afterbody is connected to the thing 10 that heavily hangs down of stainless steel, make wire stretching, as electrode.Electric wire 2 connects the input cathode of light lotus root 3, the input anode of light lotus root 3 connects the 12V power supply 5 of field effect transistor 4 connection control, the output head anode of light lotus root 3 meets VCC6, the negative pole of output end of light lotus root 3 receives the analog input I/O port of MCU7, MCU7 selects the STM32 control chip of ST company, and described MCU7 is by driving relay water pump or solenoid valve; Described water tank 1 ground wire 9.
During work, the input anode of light lotus root connects the 12V power supply of field effect transistor control, and negative pole receives the different heights of water level of water tank, and the bottom of water tank is placed and held altogether; The output head anode joint VCC of light lotus root, negative pole receives the analog input I/O port of MCU, when there being water in water tank, due to the electric conductivity of water, will make the light lotus root conducting of corresponding water level, I/O port corresponding during the conducting of light lotus root just can read high level, reads the high level of I/O port and represents that water level is to this height.When IO control mouth is high level, triode conducting, drives relay closes, thus makes solenoid valve or water pump action.Actual use procedure, also can establish multiple relay, can control startup and the stopping of water solenoid valve, ebullator, supercharge pump and air energy heat pump.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change can expected without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
