Example IV
The structure and working principle of detection circuit 1 of the invention are described further below.
As shown in fig. 6, for according to the structure chart of the detection circuit 1 of fourth embodiment of the invention.
Detection circuit 1 includes：Driver 12, signal amplifier 13 and MCU (Microcontroller Unit, microcontroller
Unit) 14.
Driver 12 connects infrared transmitter 2；Signal amplifier 13 is separately connected infrared remote receiver 3 and MCU14.Further
Ground, infrared remote receiver 3 be also connected with MCU14 perhaps 12 MCU14 of driver or driver 12 control infrared remote receiver 3 receive it is red
UV light.In other words, infrared remote receiver 3, signal amplifier 13 and MCU14 are connected with each other, alternatively, driver 12, infrared connecing
Device 3, signal amplifier 13 and MCU14 is received to be sequentially connected with.Fig. 5 shows infrared remote receiver 3, signal amplifier 13 and MCU14 phase
It connects.It is of course also possible to which individual controller is arranged in detection circuit 1, controller control infrared remote receiver 3 receives red
UV light.
Driver 12 emits infrared light with driving of preset pulse period infrared transmitter 2.
The light intensity value for the infrared light that infrared remote receiver 3 receives is converted to light intensity voltage by signal amplifier 13
Value, and light intensity voltage value is passed into MCU14.
The light intensity voltage value that MCU14 receiving signal amplifier 13 transmits, and it is stifled according to light intensity voltage value to determine that filter screen is stained with
Degree.
In the present embodiment, MCU14 counts being averaged for the light intensity voltage value that signal amplifier 13 transmits in preset time period
Value, and determine that filter screen is stained with stifled degree according to the average value of light intensity voltage value.
In the present embodiment, the workflow of 1 all parts of detection circuit is as follows：
Step S1, driver 12 drive infrared transmitter 2 to send infrared light to filter screen 4 according to the predetermined pulse period.
Step S2, MCU14 control the infrared light that infrared remote receiver 3 receives the reflection of filter screen 4.
The infrared light that infrared transmitter 2 is sent passes through module shell 5 and reaches filter screen 4, due to having accumulated on filter screen 4
Dust, so infrared light will be reflected by dust, the infrared light of reflection passes through module shell 5 in whole or in part, red
Outer receiver 3 receives.
Step S3, signal amplifier 13 sample the light intensity of the received infrared light of infrared remote receiver 3, and will
Sampled value is converted to light intensity voltage value.
The reflected infrared light of filter screen is more, and the intensity of infrared light is stronger, and light intensity voltage value is bigger, illustrates to filter
It is higher that net is stained with stifled degree.
The reflected infrared light of filter screen is fewer, and the intensity of infrared light is smaller, and light intensity voltage value is smaller, illustrates to filter
It is lower that net is stained with stifled degree.
Light intensity voltage value is passed to MCU14 by step S4, signal amplifier 13.
Light intensity voltage value directly can be passed to MCU14 by signal amplifier 13, or light intensity voltage value is converted through A/D
MCU14 is passed to after (analog-to-digital conversion).
Step S5, MCU14 count the average value for the light intensity voltage value that signal amplifier 13 transmits in preset time period.
Such as：Air processor be switched on every time detection filter screen be stained with stifled degree, in this way, MCU14 is in air processor
It can receive one or more light intensity voltage value of the transmitting of signal amplifier 13 after booting every time, MCU14 is counted at air
Reason device is continuously switched on 10 all light intensity voltage values received, and calculates being averaged for this 10 all light intensity voltage values
Value.
Step S6, MCU14 calculates the average value and the preset ratio for being stained with stifled saturation threshold of light intensity voltage value, by the ratio
Stifled degree is stained with as strainer.
If MCU14 does not receive a light intensity voltage value without statistics, then calculates the light intensity voltage value and preset
It is stained with the ratio of stifled saturation threshold, is stained with stifled degree for the ratio as filter screen.
