Embodiment Construction

[0023] see figure 1 , The microwave infrared induction control device of the present invention includes an infrared sensor group 10 and a microwave sensor 20 . The infrared sensor group 10 includes a first infrared sensor 12 , a second infrared sensor 14 and a third infrared sensor 16 . In the physical installation position, the second infrared sensor 14 is arranged on the axis of symmetry between the first infrared sensor 12 and the third infrared sensor 16, so that the detection angle of the infrared sensor group 10 is enlarged to 270°. The detection direction of the microwave sensor 20 is consistent with the detection direction of the second infrared sensor 14 , and is arranged above or below the second infrared sensor 14 . Each infrared sensor and microwave sensor is respectively connected to an independent amplifier (not shown in the figure), thereby suppressing signal interference among the sensors. Each infrared sensor and microwave sensor 12 is connected to a main c...

Abstract

The invention relates to a microwave infrared sensing control device and a signal processing method thereof. The microwave infrared sensing control device comprises a microwave sensor, a first infrared sensor, a second infrared sensor, a third infrared sensor, a signal amplifier and a main control module. The second infrared sensor is arranged at the position of the symmetric axis between the first infrared sensor and the third infrared sensor. The microwave sensor is arranged above or below the second infrared sensor and in the detection direction of the second infrared sensor. The main control module comprises a singlechip for processing signals and a relay, and the microwave sensor and the infrared sensors are connected to the main control module through respective signal amplifiers. Compared with the prior art, the microwave infrared sensing control device of the invention has the advantages that: the transverse and longitudinal sensitivity is improved; meanwhile, as the three infrared sensors are arranged, the range of an effective detection angle is improved and an obvious anti-interference effect is achieved.

Description

technical field [0001] The invention relates to an induction control device, in particular to a microwave infrared induction control device and a signal processing method thereof. Background technique [0002] In the field of lighting control, most of the more commonly used light control human body sensors are single sound control sensor and single infrared sensor. Among them, voice-activated sensing is mainly to control the lights by sensing sounds; infrared sensing is to control the lights to turn on and off by sensing people's walking through infrared sensors. In addition, microwave induction can also be used for sensing, which is that the signal generated by the microwave signal source is reflected by the object. According to the Doppler effect, when the body is far away, the frequency of the reflected wave decreases. When the body moves towards each other, the frequency of the reflected wave The frequency of the object increases, so the movement information of the obje...
