Water level detecting is applied to groundwater level detection, river water level detection, reservoir level detection, water level in water pool detection
Deng water-level observation can be close with sensed water level multidate information water level prediction and human society life and the relations of production, is water conservancy work
Planning, design, construction and the management of journey provide foundation.In flood-control and drought relief, water level prediction is even more important, and it is hydrologic forecast and water
The foundation of literary information.In present water level detecting system, most of is all to use manually to be periodically detected, not only efficiency
It is low, and easily produce measurement error.
Utility model content
The purpose of this utility model is to overcome drawbacks described above existing for existing water level detecting system, it is proposed that a kind of water tank
With water level detecting system, automatic water level detection and the function that auto-controlled water-pumping machine works are realized.
The utility model is realized using following technical scheme：
A kind of water tank water level detecting system, including water level detection circuit, LED circuit, reset circuit and single-chip microcomputer, it is described
Circuit is connected with single-chip microcomputer, and two input ports of single-chip microcomputer are connected with water level detection circuit, described water level detection circuit
It is made up of high water level detecting electrode a-d, resistor Rl-R4, ungated integrated circuit Dl, D3, D5, the ungated integrated circuit Dl, D3,
D5 input is in series with resistance, and the reset pin of single-chip microcomputer is connected by switching with power supply, and switch control reset pin obtains
Resetted to high level so as to realize.
Further, described LED circuit is by the integrated electricity of color-changing light-emitting diode VLl-VL3, resistor R5-R7 and NOT gate
Road D2, D4, D6 composition.
Further, described high water level detecting electrode is more than or equal to the 4mm copper insulated electric conductor system of holocentric by sectional area
Into.
Further, described resistance uses 1/4W carbon film resistors or metal film resistor.
The beneficial effects of the utility model are：
Using single-chip microcomputer as core, after measuring water level by the high water level detecting electrode in water tank, single-chip microcomputer control
Water pumper starts or stopped, and realizes that automatic water level detects and the function of auto-controlled water-pumping machine work, practicality are stronger.
Brief description of the drawings
Fig. 1 is the schematic diagram of water level detection circuit of the present utility model.
Fig. 2 is hardware connection block diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of water tank water level detecting system described in the utility model, including water level detection circuit, LED
Circuit, reset circuit and single-chip microcomputer, the circuit are connected with single-chip microcomputer, two input ports and the water level detecting electricity of single-chip microcomputer
Road is connected, and described water level detection circuit is by high water level detecting electrode a-d, resistor Rl-R4, ungated integrated circuit Dl, D3, D5
Composition, described ungated integrated circuit Dl, D3, D5 input are in series with resistance, the reset pin of single-chip microcomputer by switch with
Power supply is connected, and switch control reset pin obtains high level and resetted so as to realize, LED circuit is by color-changing light-emitting diode VLl-
VL3, resistor R5-R7 and ungated integrated circuit D2, D4, D6 composition, high water level detecting electrode is by sectional area more than or equal to 4mm's
The copper insulated electric conductor of holocentric is made, and resistance uses 1/4W carbon film resistors or metal film resistor.
It is of the present utility model as described below using process：
As shown in figure 1, at different height in water tank, installation high water level detecting electrode a-d is reflecting SEA LEVEL VARIATION
Situation, when high water level detecting electrode d is in water, due to the electric action of water, power supply connects with electrode d, makes NOT gate Dl input
End is in high level, and its output end is changed into low level, and D2 output end is high level, now the red light emitting diodes inside VLl
Do not work, green LED lights.When water level is down to below electrode d, Dl input is changed into low level, and output end is changed into
High level, D2 output end are changed into low level, light the red light emitting diodes inside VLl, and green LED extinguishes,
The operation principle of remaining each road water level indicating circuit is identical with this.
VLl and VL3 is respectively intended to indicate low water level and high water level, when cistern water level is less than level electrode d, VLl-VL3
Equal burn red, now single-chip microcomputer detect high level so as to controlled motor rotate, drive water pump Tank Injection Water；It is in pond
During 1/2 water level, VLl, VL2 glow green, VL3 burn reds, maintain both stateful；When water level reaches high water level electrode b,
The equal glow greens of VLl-VL3, now single-chip microcomputer detect that low level stops operating so as to controlled motor, water pump stops water filling.
Certainly, the above is only preferred embodiment of the present utility model, it is impossible to is considered as being used to limit to this practicality newly
The scope of embodiments of type.The utility model is also not limited to the example above, and those skilled in the art are in this reality
With equivalent change and improvement made in new essential scope etc., patent covering scope of the present utility model all should be belonged to
It is interior.
