Detailed description of the invention
Fig. 1 is the structural schematic diagram that system is monitored in first embodiment of the invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with drawings and the embodiments,
The present invention will be described in further detail.
In this specification, it should be noted that term " connection " shall be understood in a broad sense, such as can be a connection, can also
Being connected by intermediary, for the ordinary skill in the art, it can understand as the case may be and specifically contain
Justice.
With reference to Fig. 1, first embodiment of the invention provides a kind of water quantity monitoring system, for monitoring in water storage container 1
Water, the monitoring system include the light generating unit 2 set on 1 bottom of water storage container, and are set to 1 top of water storage container
Optical filter 3 and light receiving unit 4；The light receiving unit 4 is received by the smooth transmitting of generating unit 2 and through the optical filter
Electric current is generated after the light of 3 filterings.
When light is radiated on light receiving unit, light receiving unit can be made to generate electric current, can determine by size of current
The intensity of irradiation light；By the setting of light generating unit in water storage container bottom, when being equipped with water in water storage container, hydrone mainly exists
There is absorption wave crest to light at 1620nm and 3400nm, i.e. hydrone has absorption to light energy；Therefore, it is sent out by light generating unit
Different size of electric current can be inspired by penetrating and being radiated in light absorption units through the different amounts of light with absorption.The present invention passes through
The size of current generated by light receiving unit is monitored, real-time monitoring can be carried out to the water in water storage container.
Preferably, the smooth generating unit 2 is infrared light supply, the central wavelength of the optical filter is 1620nm.By setting
Optical filter is set, enables to monitor more acurrate.
It should be noted that in the present embodiment, since light received on light receiving unit only has certain area
Light beam, therefore volume V=S × h of the water of the beam energy is absorbed in water storage container；Wherein S is that light receiving unit receives light
Area, h be water storage container in water height.It can be directly determined in water storage container by the size of current that light receiving unit generates
The height of corresponding water, so that the volume of the water in water storage container may further be determined.
Monitoring system in the present invention is particularly suitable for being monitored the water in humidifier.Due in humidifier
What is be usually added into is pure water, and the impurity in water can ignore the reflection of spectrum, so that the monitoring of water is more acurrate.
Further, the monitoring system further includes processor 5 and storage unit (not shown), the processor 5
The light receiving unit 4 is connected, a plurality of instruction is stored in the storage unit, when described instruction is executed by the processor 5
The processor 5 is set to connect the current data that the generation of light receiving unit 4 is stated in acquisition.This programme can pass through processor automatic collection electricity
Flow data determines the water in water storage container.
It further, further include water-electric current calibration curve, the water-electric current calibration curve in the storage unit
It is to absorb the light that light generating unit emits through different amounts of pure water, then the light-receiving list is exposed to after optical filter filters
Member generates different electric currents, the relation curve of the water of pure water and its corresponding electric current.
This programme can directly establish the relationship between electric current and water by setting water-electric current calibration curve, use
The monitoring system of this programme only need to can calculate corresponding real-time water, so that monitoring knot by acquiring real-time current
Fruit is more intuitive, is easy to judge.
Further, the monitoring system further includes alarm unit (not shown), when real-time water is lower than preset value,
The alarm unit sounds an alarm, and reminds user into water storage container plus water；The real-time water is that the electric current of real-time monitoring exists
Corresponding water data in water-electric current calibration curve.It should be noted that the preset value of water have no it is specifically limited, can be with
It is set according to use demand.
Further, the light receiving unit is pyroelectric detector.This programme can accurately reflect after water absorbs
Light energy size, so as to accurately reflect water.
Second embodiment of the invention provides a kind of water quantity monitoring method, the water quantity monitoring system provided using first embodiment
System the monitoring method is monitored to the water in water storage container the following steps are included:
Emit and pass through the water in water storage container and optical filter by light generating unit using the light receiving unit real-time reception
Light obtains real-time current；
According to the real-time current, corresponding water value determines the water in the water storage container in water-electric current calibration curve
Amount；The water-electric current calibration curve is that the light of light generating unit transmitting is absorbed through different amounts of pure water, then through optical filter mistake
The light receiving unit is exposed to after filter and generates different electric currents, and the relationship between the water of pure water and its corresponding electric current is bent
Line.
