Description of the drawings
Fig. 1 is the structure diagram of infrared ray stool and urine detection device.
Fig. 2 is the operating diagram of infrared ray stool and urine detection device.
Fig. 3 is the circuit diagram of infrared ray stool and urine detection device.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
In the embodiment of the present invention, a kind of infrared ray stool and urine detection device, including multiple infrared transmitting devices and multiple
Infrared receiver passes through the arrival of multiple infrared transmitting devices and multiple infrared receivers detection stool.
Distance is less than 27mm between the multiple infrared transmitting device.
Distance is less than 27mm between the multiple infrared receiver.
One infrared transmitting device only corresponds to an infrared receiver.
One infrared transmitting device and infrared receiver are smaller than 75mm.
Referring to Fig. 1, IR1~IR6 is infrared transmitting device, PT1~PT6 is infrared receiver, it can be seen that
When IR3 emits, if there is foreign matter appear in IR2, IR3 and IR4 composition triangle in the range of, then this object can lead to
It crosses：The signal that blocking light receives PT3 generates variation；Reflection light makes the signal intensity that PT2 and PT4 are received.Exactly
Detect that the variation of this signal has determined that object enters detection range.
Referring to Fig. 2, it can be seen that pass through in the range of the receiving of PT3, made by the effect respectively of IR3 and IR2, IR4 whole
The signal all standing in a region.That is the object occurred in the range of the triangle that PT2, PT3 and PT4 are formed can pass through IR3
It is fed back on PT3 with the signal that IR2, IR4 are sent out.
In fig. 1 and 2 it may be seen that transmitting signal covers all areas；All faces can also be covered by receiving signal
Product.Namely our mode has covered the region for needing to detect, and has accomplished comprehensive covering.
The circuit that we design：IR1, IR3, IR5 are one group, and IR2, IR4, IR6 are two groups.Emission state is three kinds of moulds
Formula：Mode A：One group of power supply, two groups are not powered；B-mode：Two groups of power supplies, one group is not powered；C mode：First, it does not power for two groups；
Three models are detected with the speed of 256Hz, and A, C, B, C, A cycle are gone down.
Detection state：PT1-PT6 six is detected respectively under Three models.Detection obtains one group of data under mode A,
One group of data is detected under C mode, one group of data is obtained under B-mode.C mode data are the data of environment in this way, pass through A-C
Pattern obtains the data of a removal environmental disturbances；Similary B-C patterns can obtain the data of a removal environmental disturbances；This two
The parameter of a removal environmental data is referred to as scene, is foreign matter intrusion once data deviate.
As shown in figure 3, this part is allocated as four parts by topology requirement, three dotted line frames are respectively the circuit part of the present invention
A part of other are a part.In three dotted line frames is all the element of transmitting and reception, electricity of the signal processing outside dotted line frame
Road.
Infrared transmitting circuit is controlled by Q7, Q8.Q7, Q8 are controlled by microcontroller, light two groups of transmittings of D135 and D246 respectively
Infrared ray.
PT1-PT6 is coupled with each reception pipe, and wherein resistance R69, R70, R71 provides bias voltage for reception pipe；
R80, R81, R82 and C72, C62, C61 are filtering, reduce (another group of interference signal：R74, R75, R76 are provided partially for reception pipe
Put voltage；R77, R78, R79 and C73, C74, C75 are filtering, reduce interference signal)；
The ADC interface that PT1-PT6 is sent into microcontroller carries out level measurement.
The flow of microcontroller：
Control Q7, Q8 are not turned on, and measure the voltage of PT1-PT6, each to receive when this voltage is reflected in all not luminous
The intensity for the light that pipe receives.Reflect influence of the ambient light to measurement.
Control Q7 conductings, Q8 are not turned on, and measure the voltage of PT1-PT6, this voltage is reflected in transmitting tube D2, D4, D6 hair
Light time, the intensity for the light that each reception pipe receives, react be intensity in environment and the coefficient light of luminous tube, such as
Fruit removes the influence of ambient light, means that practical light intensity distributions.
Control Q7 is not turned on, Q8 conductings, measures the voltage of PT1-PT6, this voltage is reflected in transmitting tube D1, D3, D5 hair
Light time, the intensity for the light that each reception pipe receives, react be intensity in environment and the coefficient light of luminous tube, such as
Fruit removes the influence of ambient light, means that practical light intensity distributions.
The measurement of these three intensity is 256 times per second.Once the intensity for measuring light change mean light path by
Interference represents that foreign matter enters measurement range, starts intelligence control system at this time.
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
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Profit requirement rather than above description limit, it is intended that all by what is fallen within the meaning and scope of the equivalent requirements of the claims
Variation is included within the present invention.Any reference numeral in claim should not be considered as to the involved claim of limitation.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in each embodiment can also be properly combined, forms those skilled in the art
The other embodiment being appreciated that.
