Embodiment 1

[0056] like figure 1 As shown in the figure, this embodiment provides a transparent conductive film intelligent defogging system based on a single-chip microcomputer. The intelligent defogging system is used to prevent the window glass of the vehicle from fogging, including: a temperature sensor group, a humidity sensor 5, a transparent conductive film 7 , control switch 6 , microcontroller 10 , and memory 8 .

[0057] The temperature sensor group includes a first temperature sensor 1, a second temperature sensor 2, a third temperature sensor 3, and a fourth temperature sensor 4; the first temperature sensor 1 is used to measure the temperature T of the front windshield of the vehicle 1 ; The second temperature sensor 2 is used to measure the temperature T of the window glass on the left side of the vehicle near the rearview mirror 2 ; The third temperature sensor 3 is used to measure the temperature T of the window glass on the right side of the vehicle near the rearview mir...

Embodiment 2

[0105] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the intelligent defogging system also includes a dew condensation sensor group 9, and the dew condensation sensor group 9 includes a plurality of The window glass on the left side near the rearview mirror, and the dew condensation sensor on the right side of the vehicle near the rearview mirror, the condensation sensor is used to detect whether there is condensation on the glass. The single-chip microcomputer 10 is electrically connected, and the single-chip microcomputer 10 is also used for obtaining the detection result of the dew condensation sensor. The control circuit of the intelligent defogging system in this embodiment is as follows: Figure 5 shown.

[0106] Wherein, in step S3 of the control process of the single-chip microcomputer 10 in this embodiment, after it is determined that the current glass is not fogged, the single-chip microcomputer 10 cont...

Abstract

The invention belongs to the technical field of vehicle safety systems, in particular to a transparent conductive film intelligent defogging system based on a single chip microcomputer. The intelligent defogging system is used to prevent fogging of the window glass of the vehicle, and includes: a temperature sensor group, a humidity sensor, a transparent conductive film, a control switch, a single-chip microcomputer, and a memory. The temperature sensor group is used to measure the temperature of the window glass and the ambient temperature inside the vehicle. The humidity sensor is used to measure the ambient humidity of the vehicle; the transparent conductive film is used to heat the glass. The control switch is used to control the running state of the transparent conductive film. The single-chip microcomputer receives the detection results of the temperature sensor group and the humidity sensor, and automatically controls the transparent conductive film through the control switch according to the detection results. The memory is used to store various data of the system operation process. The system solves the hidden safety hazard that the window glass of the vehicle is easily fogged during the running process, and at the same time does not require manual intervention, and the power consumption of the device is low.

Description

technical field [0001] The invention belongs to the technical field of vehicle safety systems, in particular to a transparent conductive film intelligent defogging system based on a single chip microcomputer. Background technique [0002] During the driving process of the vehicle, the outdoor weather conditions and the respiration of the people inside the vehicle will affect the vehicle environment; among them, temperature and humidity are the factors that have the greatest impact on the vehicle interior environment. Under normal conditions, when the water vapor contacts the wall with a temperature lower than the dew point temperature, the water vapor will condense into a liquid on the wall. The temperature of the window glass is lower than the dew point temperature of the water vapor in the car, resulting in a supersaturated state of water vapor; this causes the water vapor to accumulate and condense on the inside of the window glass, thereby forming a water mist that block...
