Infrared obstacle distance detection circuit

The utility model discloses an infrared obstacle distance detection circuit, which comprises an infrared emission module, an infrared receiving module and an output signal adjusting module, and is characterized in that the infrared emission module generates first infrared rays for testing the obstacle distance according to current signals output by an input and output module; the infrared receiving module receives second infrared rays emitted by the first infrared rays passing through an obstacle, converts the second infrared rays into electric signals and outputs the electric signals to the input and output module; the output signal adjusting module controls the voltage value to be reduced to a preset voltage when the voltage value is greater than the preset voltage; or when the voltage value is smaller than the preset voltage, the voltage value is controlled to be increased to the preset voltage, and then the output signal adjusting module adjusts the signal intensity of the electricsignal converted from th
