Problems solved by technology

Since the pyroelectric sensor is sensitive to the temperature change of the air environment, and the air flow has a great influence on the sensor, the sensing products of the pyroelectric sensor are mainly used indoors. If they are used outdoors, the probability of malfunction is very high, or even impossible. Normal work, so that the use of the human sensor switch is limited

Embodiment Construction

[0016] The technical solution of the present invention will be described below in conjunction with specific embodiments.

[0017] Such as Figure 1-Figure 3 Shown:

[0018] The working principle of microwave induction switch:

[0019] When using AC power, input AC 110 / 220V voltage from power input terminals A and B. After switching power supply, 6V DC power is generated after rectification and stabilization, which is input to a low-power regulator; when using DC power, it is input from the power supply The terminals A and B input the DC 6-24V power supply to the low-power regulator, and the low-power regulator HT7550 outputs a 5V DC voltage for the microwave induction switch circuit to work. The microwave movement sensor M is controlled by Q1 driven by the single-chip HT46R47, which emits microwave signals regularly and directionally. When someone moves within the set sensing distance, the microwave movement sensor M senses the movement signal. This signal is amplified by a two-sta...

Abstract

The invention relates to a microwave inductive switch using a microwave moving sensor to detect the movement of a human body. The switch comprises a switch power supply circuit, a voltage regulator circuit, a microwave moving sensor, a signal amplifying circuit, a singlechip control circuit, a relay output circuit and the like. The switch works by using the 110v or 220v alternating current power supply or using 6 to 20v direct current supply. A standard power bottom box of 86 * 86 mm is used, thereby other switches can be conveniently installed and replaced. The microwave moving sensor has the working frequency of 10 to 12 Ghz, has the characters of reliable performance, low power consumption, convenient installation and wide voltage range and uses the alternating and the direct current power supplies. The switch can be used in the fields of security protection, electric appliance, passageway electricity saving illumination, automatic induction electricity saving illumination of underground car parks as well as indoor and outdoor device inductive control.

Description

Technical field [0001] The invention relates to the application technology of a microwave mobile sensor, in particular to a microwave induction switch. Background technique [0002] At present, human body automatic induction switches are mainly based on pyroelectric (PIR) sensors, which are mainly used for corridor power-saving lighting and indoor security. Because pyroelectric sensors are sensitive to changes in the air environment temperature, and air flow has a great influence on the sensor, pyroelectric sensor-like induction products are mainly used indoors. If used outdoors, the probability of malfunction is high, or even impossible Normal work restricts the use of the human body sensor switch. The microwave mobile sensor is a sensor that uses the Doppler principle to detect the movement of the human body. The sensor itself generates a signal with a fixed frequency, and the signal is emitted from the transmitting antenna. When a human body moves within the detection range, ...
