Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Alternatively, the light emitting module 10 may be an infrared light emitting module, an LED light emitting module, a fluorescent lamp, or other light source; preferably, the light emitting module 10 is an infrared light emitting module, and the corresponding light receiving module 20 is an infrared light receiving module. The light emitting module 10 and the light receiving module 20 are located outside the transparent dirt suction pipe 40, the transparent dirt suction pipe 40 is used for absorbing and transporting cleaning objects generated after the surfaces of the objects are cleaned, and the transparent dirt suction pipe 40 is made of a light-transmitting material and can transmit and reflect light emitted by the light emitting module 10. Alternatively, the transparent soil pick-up tube 40 is a circular tube.
The working principle of the object surface dirt degree detection device is as follows: the processor 30 controls the light emitting module 10 to emit the emitting light with the preset illumination intensity, the emitting light is emitted into the light receiving module 20 through the transparent dirt suction pipe 40, and the emitting light is attenuated after being absorbed and reflected by the transparent dirt suction pipe 40 and the cleaning objects inside the transparent dirt suction pipe. The light receiving module 20 sends the intensity of the received light to the processor 30, and the processor 30 searches for the contamination degree corresponding to the intensity of the received light according to the light intensity and the contamination degree comparison table. The comparison table of the light intensity and the dirt degree is a corresponding relationship between the intensity of received light and the dirt degree on the surface of the object, that is, each intensity of received light has a corresponding dirt degree, and if the intensity of received light is smaller, the absorption and reflection of the transparent dirt suction pipe 40 and the cleaning object inside the transparent dirt suction pipe to the emitted light are larger, and the dirt degree on the surface of the object is larger; if the intensity of the received light is larger, the absorption and reflection of the emitted light by the transparent soil suction pipe 40 and the cleaning object inside the transparent soil suction pipe are smaller, and the degree of the surface of the object is smaller. Alternatively, the light intensity and stain level look-up table is stored in the processor 30, or the light intensity and stain level look-up table is stored in a memory communicatively connected to the processor 30.
It can be understood that the light intensity and contamination degree comparison table is related to the preset illumination intensity and the distance between the light emitting module 10 and the light receiving module 20, and different distances correspond to different light intensity and contamination degree comparison tables under the same preset illumination intensity; when the distances are the same, different preset illumination intensities correspond to different light intensity and dirty degree comparison tables. In the actual use process, the corresponding preset illumination intensity and distance can be selected after the light intensity and the pollution degree comparison table is selected; the light intensity and contamination level comparison table may be prepared according to the preset light intensity and distance after the light emitting module 10 and the light receiving module 20 are installed.

For example, referring to fig. 2b, the transparent soil pick-up pipe 40 is a circular pipe, the transparent soil pick-up pipe 40 is located between the light emitting module 10 and the light receiving module 20, the light emitting module 10 and the light receiving module 20 are located on the same vertical section of the transparent soil pick-up pipe 40, and a connection line between the light emitting module 10 and the light receiving module 20 passes through the axis of the transparent soil pick-up pipe 40.
In the object surface contamination degree detection apparatus according to some embodiments, referring to fig. 3a, the transparent contamination suction pipe 40 is not located on the transmission light path of the light emitting module 10 and the light receiving module 20, the light receiving module 20 is located on the light path after the emission light is reflected by the transparent contamination suction pipe 40, and the emission light is reflected by the transparent contamination suction pipe 40 and then enters the light receiving module 20. For example, referring to fig. 3b, the transparent soil pick-up tube 40 is a circular tube, the light emitting module 10 and the light receiving module 20 are located on the same vertical section of the transparent soil pick-up tube 40, and a line connecting the centers of the light emitting module 10 and the light receiving module 20 and the vertical section of the transparent soil pick-up tube 40 forms an included angle of 90 °.
In a preferred embodiment, the device for detecting the degree of contamination on the surface of an object of the present embodiment comprises a light emitting module 10, a light receiving module 20, a voltage dividing module 50 and a processor 30, wherein the light emitting module 10 and the light receiving module 20 are located outside a transparent dirt suction pipe 40, and the transparent dirt suction pipe 40 is used for absorbing cleaning objects generated after the surface of the object is cleaned. Alternatively, the voltage dividing module 50 is a voltage dividing resistor. The processor 30 is connected to the light emitting module 10, the light receiving module 20 is connected to the voltage dividing module 50 in series, one end of the light receiving module 20 connected to the voltage dividing module 50 in series is connected to the voltage supply terminal (VDD), and the other end is grounded. Alternatively, there are two ways of connecting the light receiving module 20 and the voltage dividing module 50 in series:
the first series mode: referring to fig. 4a, the voltage dividing module 50 is connected to the voltage supply terminal (VDD), the light receiving module 20 is grounded, and the connection point of the light receiving module 20 and the voltage dividing module 50 is connected to the processor 30, so that the processor 30 collects the divided voltage on the light receiving module 20.
The second series connection mode: referring to fig. 4b, the light receiving module 20 is connected to a voltage supply terminal (VDD), the voltage dividing module 50 is grounded, and a connection point of the light receiving module 20 and the voltage dividing module 50 is connected to the processor 30, so that the processor 30 collects the divided voltage on the voltage dividing module 50.
In the present embodiment, a first series connection manner is taken as an example for principle explanation, and a second series connection manner can be referred to for implementation. The operating principle of the device for detecting the surface contamination degree of the object in the first series connection mode is as follows:
the processor 30 controls the light emitting module 10 to emit the emitting light with the preset illumination intensity, and the emitting light is emitted into the light receiving module 20 through the transparent dirt suction pipe 40. The resistance of the light receiving module 20 is different under different illumination conditions, and the resistance of the light receiving module 20 may be inversely proportional to the received light intensity, i.e. the larger the received light intensity is, the smaller the resistance of the light receiving module 20 is; the smaller the received light intensity is, the larger the resistance value of the light receiving module 20 is. The resistance value of the light receiving module 20 may also be proportional to the received light intensity, i.e. the greater the received light intensity, the greater the resistance value of the light receiving module 20; the smaller the received light intensity is, the smaller the resistance value of the light receiving module 20 is.
The light receiving module 20 and the voltage dividing module 50 are connected in series, and according to the principle of serial voltage division, when the resistance of the light receiving module 20 changes, the divided voltage of the light receiving module 20 and the voltage dividing module 50 changes correspondingly, so that the change of the intensity of the received light on the light receiving module 20 can be reflected by collecting the divided voltage of the light receiving module 20, and further the influence of the transparent soil pick-up tube 40 on the emitted light can be reflected. The processor 30 collects the divided voltage of the light receiving module 20, and searches for the contamination degree corresponding to the divided voltage according to the voltage and contamination degree comparison table. Alternatively, the processor 30 may collect the divided voltage of the light receiving module 20 through a voltage sampling circuit. The voltage and dirt degree comparison table is a corresponding relation between a divided voltage and the dirt degree of the surface of an object, namely, each received voltage has a corresponding dirt degree, and the voltage and dirt degree comparison table is described in two cases as follows:
in the first case: when the resistance value of the light receiving module 20 is inversely proportional to the intensity of the received light, if the divided voltage of the light receiving module 20 is smaller, it indicates that the intensity of the received light of the light receiving module 20 is larger, and further indicates that the degree of contamination is smaller; if the divided voltage of the light receiving module 20 is larger, it indicates that the intensity of the received light of the light receiving module 20 is smaller, and further indicates that the degree of contamination is larger.
In the second case: when the resistance value of the light receiving module 20 is proportional to the intensity of the received light, if the divided voltage of the light receiving module 20 is smaller, it indicates that the intensity of the received light of the light receiving module 20 is smaller, and further indicates that the degree of contamination is larger; if the divided voltage of the light receiving module 20 is larger, it indicates that the intensity of the received light of the light receiving module 20 is larger, and further indicates that the degree of contamination is smaller.
It can be understood that the voltage and contamination level comparison table is related to the preset illumination intensity and the distance between the light emitting module 10 and the light receiving module 20, and different distances correspond to different voltage and contamination level comparison tables under the same preset illumination intensity; when the distances are the same, different preset illumination intensities correspond to different voltage and pollution degree comparison tables. In the actual use process, the corresponding preset illumination intensity and distance can be selected after the voltage and the pollution degree comparison table is selected; alternatively, after the light emitting module 10 and the light receiving module 20 are mounted, a voltage and contamination level comparison table may be prepared according to the preset illumination intensity and distance. Alternatively, the voltage to soil comparison table is stored in the processor 30, or the voltage to soil comparison table is stored in a memory communicatively coupled to the processor 30.
This embodiment utilizes the light to propagate the principle and establishes ties the partial pressure principle, changes light receiving module 20's resistance value through the influence that transparent soil pick-up pipe propagated to light, and then detects the dirty degree in object surface by establishing ties the partial pressure, realizes the automated inspection of the dirty degree in object surface.
In a preferred embodiment, referring to fig. 5, in this embodiment, the light emitting module 10 includes a resistor R1 and an infrared emitting tube LED1, the light receiving module 20 is an infrared receiving tube LED2, and the voltage dividing module 50 is a resistor R2. The first end of the resistor R1 is connected with a voltage supply terminal (VDD), the second end of the resistor R1 is grounded through the infrared emitting tube LED1, and the infrared emitting tube LED1 is used for emitting infrared light. The first end of the resistor R2 is connected with a voltage supply end (VDD), the second end of the resistor R2 is connected with the processor 30, the second end of the resistor R2 is grounded through the infrared receiving tube LED2, the infrared receiving tube LED2 is used for receiving infrared light, and the resistance value of the infrared receiving tube LED2 changes along with the change of the infrared light. The infrared transmitting tube LED1 and the infrared receiving tube LED2 are installed as shown in fig. 2 b. The voltage of the voltage supply terminal (VDD) is 5V.
The working principle of the object surface contamination degree detection circuit is as follows:
if the transparent dirt suction pipe 40 has a small amount of cleaned objects, and when the amount of cleaned objects is close to the amount of cleaned objects, the infrared light emitted by the infrared emission tube LED1 directly passes through the transparent dirt suction pipe 40 to reach the infrared receiving tube LED2, and basically no loss exists, at this time, the resistance of the infrared receiving tube LED2 is small, and the voltage collected by the processor 30 tends to zero. That is, if the voltage collected by the processor 30 goes to zero, it indicates that the clear soil in the transparent soil pipe 40 is particularly low, and thus indicates that the surface of the object is less soiled.
If the number of the cleaning objects in the transparent dirt suction pipe 40 is large, the infrared light emitted by the infrared emitting tube LED1 is substantially absorbed by the cleaning objects, almost no infrared light can pass through the transparent dirt suction pipe 40 to reach the infrared receiving tube LED2, at this time, the resistance of the infrared receiving tube LED2 is large, and the voltage collected by the processor 30 tends to the voltage supply terminal (VDD), which is about 5V. That is, if the voltage collected by the processor 30 is approximately equal to 5V, it indicates that there is a particularly large amount of cleaning material in the transparent soil suction pipe 40, and thus indicates that the surface of the object is stained to a greater degree.
If the cleaning in the transparent soil suction pipe 40 is between a particularly small and a particularly large amount, the voltage collected by the processor 30 is between 0V and 5V. That is, if the voltage collected by the processor 30 is between 0V and 5V, the degree of contamination of the surface of the object can be obtained according to the voltage and contamination level look-up table.
In a preferred embodiment, referring to fig. 6, the apparatus for detecting the degree of contamination on the surface of an object of the present embodiment includes a light emitting module 10, a light receiving module 20, a current limiting module 60, and a processor 30, wherein the processor 30 is connected to the light emitting module 10, the light receiving module 20 and the current limiting module 60 are connected in series, and after the series connection, one end is connected to a voltage supply terminal (VDD), and the other end is connected to the processor 30. In the present embodiment, the current limiting module 60 is connected to the voltage supply terminal (VDD), and the light receiving module 20 is connected to the processor 30 for illustration; the case where the light receiving module 20 is connected to the voltage supply terminal (VDD), and the current limiting module 60 is connected to the processor 30 can be implemented with reference to the present embodiment. The light emitting module 10 and the light receiving module 20 are located outside the transparent soil suction pipe 40, and the transparent soil suction pipe 40 is used for absorbing cleaning objects generated after the surfaces of the objects are cleaned. Alternatively, current limiting module 60 is a current limiting resistor.
The working principle of the object surface dirt degree detection device is as follows: the processor 30 controls the light emitting module 10 to emit the emitting light with the preset illumination intensity, and the emitting light is emitted into the light receiving module 20 through the transparent dirt suction pipe 40. The resistance of the light receiving module 20 is different under different illumination conditions, and the resistance of the light receiving module 20 may be inversely proportional to the received light intensity, i.e. the larger the received light intensity is, the smaller the resistance of the light receiving module 20 is; the smaller the received light intensity is, the larger the resistance value of the light receiving module 20 is. The resistance value of the light receiving module 20 may also be proportional to the received light intensity, i.e. the greater the received light intensity, the greater the resistance value of the light receiving module 20; the smaller the received light intensity is, the smaller the resistance value of the light receiving module 20 is.
The light receiving module 20 has different resistance values under different lighting conditions, and on the premise that the voltage supply terminal (VDD) is not changed, the change of the light receiving module 20 may cause the change of the series current flowing through the series circuit of the light receiving module 20 and the current limiting module 60. The processor 30 collects the series current of the series circuit of the light receiving module 20 and the current limiting module 60, and looks up the contamination degree corresponding to the series current according to a current and contamination degree comparison table, wherein the current and contamination degree comparison table is the corresponding relationship between the series current and the contamination degree of the object surface, and the current and contamination degree comparison table is described in two cases as follows:
in the first case: when the resistance value of the light receiving module 20 is inversely proportional to the received light intensity, if the series current of the series circuit of the light receiving module 20 and the current limiting module 60 is smaller, the resistance of the light receiving module 20 is larger, and further the received light intensity of the light receiving module 20 is smaller, and further the degree of contamination is larger; if the series current of the series circuit of the light receiving module 20 and the current limiting module 60 is larger, it means that the resistance of the light receiving module 20 is smaller, and further means that the intensity of the received light of the light receiving module 20 is larger, and further means that the degree of contamination is smaller.
In the second case: when the resistance value of the light receiving module 20 is proportional to the intensity of the received light, if the series current of the series circuit of the light receiving module 20 and the current limiting module 60 is smaller, it indicates that the resistance of the light receiving module 20 is larger, and further indicates that the intensity of the received light of the light receiving module 20 is larger, and further indicates that the degree of contamination is smaller; if the series current of the series circuit of the light receiving module 20 and the current limiting module 60 is larger, it means that the resistance of the light receiving module 20 is smaller, and further means that the intensity of the received light of the light receiving module 20 is smaller, and further means that the degree of contamination is larger.
Alternatively, the processor 30 may collect the series current of the light receiving module 20 through a current sampling circuit. The current and dirt degree comparison table is the corresponding relation between the series current and the dirt degree of the surface of the object, namely each series current has the corresponding dirt degree. The current and pollution degree comparison table is related to the preset illumination intensity and the distance between the light emitting module 10 and the light receiving module 20, and different distances correspond to different current and pollution degree comparison tables under the same preset illumination intensity; when the distances are the same, different preset illumination intensities correspond to different current and pollution degree comparison tables. In the actual use process, the corresponding preset illumination intensity and distance can be selected after the current and pollution degree comparison table is selected; it is also possible to prepare a current and contamination level comparison table according to the preset illumination intensity and distance after the light emitting module 10 and the light receiving module 20 are installed.
