Illuminating device based on microwave radar induction

Abstract

The invention discloses a microwave radar induction lighting device. A microwave transceiver, a radar intermediate frequency amplification circuit, a signal processor and the like are integrated on a single chip at the same time, and the device has good consistency and ultrahigh cost performance. Due to the fact that a self-adaptive calibration algorithm is integrated on the chip, various interference problems can be effectively solved, and reliability and practicability of the sensor are greatly improved. An ultra-low power consumption framework is adopted, power consumption is low, and wide voltage is supported; a signal processor is integrated in the chip and can directly output an inductive control signal, and a complete microwave inductive sensor is formed by matching a small number of components on the periphery; manual control can be reduced, when a person enters the detection range of the device, the microwave detector works to light the lamp, and when the person leaves the detection range, the lamp is automatically turned off. The device has strong anti-interference capability and is not interfered by external environmental factors.

Description

technical field [0001] The present invention relates to the technical field of multimedia processing, in particular to a microwave radar sensing lighting device. Background technique [0002] The traditional lighting switch device is simple, effective and intuitive for lighting control, but it relies too much on the personal ability of the controller, the control is relatively scattered and cannot be effectively managed, and its real-time and automation degree is too low. The use of a microwave induction device is to solve the shortcomings of the traditional switch device, and the microwave induction device is not disturbed by external factors such as wind and heat. Microwave induction is non-directional, as long as someone or other objects move in the monitoring area of ​​the device, it can be controlled. This microwave radar induction device is an ideal replacement for traditional switching devices. [0003] The existing traditional lighting control methods are mostly man...

Problems solved by technology

Microwave sensor is an independent electronic component. It is a circuit module composed of circuit board and microwave devices. It has a large appearance and volume. When it is used, it needs to design active peripheral circuits to work. At present, most of them appear in the form of component products. In the market, due to the high frequency of microwave detection signals, the design circuit has certain technical requirements for object movement sensing signal processing, which limits the application of microwave sensors.
