Abstract

The invention discloses an HA digital infrared correlation photoelectric switch sensor. The switch sensor comprises an infrared transmitter circuit and an infrared receiver circuit, the infrared transmitter circuit comprises a first power supply circuit, a first single-chip microcomputer and an infrared emission driving circuit, and the infrared receiver circuit comprises a second power supply circuit, a second single-chip microcomputer, an infrared receiving circuit and a signal output circuit; the first single-chip microcomputer U1 and the second single-chip microcomputer U1 both adopt STC15W104 single-chip microcomputers and are packaged by SOP8, and an internal crystal oscillator reaches 33MHz. Compared with an analog infrared correlation sensor, the temperature drift problem caused bylong-time operation of the analog sensor is solved, the circuit is simple, the number of circuit devices is small, the anti-interference capability is high, and the circuit is suitable for long-timeuninterrupted power operation of the underground coal mine all the year round.

Description

technical field [0001] The invention relates to an infrared sensor, in particular to an HA digital infrared through-beam photoelectric switch sensor. Background technique [0002] Most infrared photoelectric switch sensors on the market are analog, and the shortcomings of analog infrared switch sensors are temperature drift after long-term operation, resulting in product instability and damage, causing wrong input signals to the system, high maintenance costs, and anti-interference ability It is not strong, and the quality requirements of electronic components are very high. A slight discomfort (such as jittering due to unstable power supply, etc.) will damage the photoelectric switch sensor, which will affect the operation of equipment using infrared sensors. The infrared emission angle is 3-5 degrees smaller, especially not suitable for the underground environment of coal mines. The only way to maintain is to replace the new infrared sensor.
