An infrared radiation device

Abstract

The invention discloses an active infrared intrusion detector. The active infrared intrusion detector mainly comprises an infrared emitting circuit, an infrared receiving circuit, a radio frequency circuit, a vibration sensor, microswitches and a mechanical telescopic arm. A radio frequency module, the vibration sensor and the infrared receiving circuit are installed on an infrared receiving circuit board. The microswitches and the mechanical telescopic arm and mechanical telescopic arms are installed outside an infrared emitting circuit board / the infrared receiving circuit. Compared with the prior art, a low-voltage battery is used for supplying power, an efficient power supply management method is used, power consumption is greatly reduced, and an external power source is not needed; meanwhile, the radio frequency module is used for sending feedback signals, no connecting line between the radio frequency module and a master controller of the active infrared intrusion detector is needed, and installation and usage are greatly facilitated.

Description

technical field [0001] The invention relates to an infrared directing device, in particular to an infrared directing device applied to an electric rolling door. Background technique [0002] At present, the infrared radiation devices on the market consume a lot of power and require an external power supply. They are not suitable for applications with extremely low power consumption requirements. For example, when they are applied to electric rolling door machines, the main controller needs to provide power. It makes the wiring very inconvenient, and makes the power consumption of the system too large. At the same time, the signal feedback of the existing infrared radiation device also adopts wired connection, which also brings inconvenience to the wiring. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides an infrared directing device. The infrared radiation device has extremely low power consumption and does not ...
