Abstract

The invention provides an inductive type human body approach warning controller. The inductive type human body approach warning controller is characterized by comprising a 12V direct current power source, a microwave induction and detection circuit, a monostability time-delay circuit, a direct current relay control and warning circuit and a status indication device. The model number adopted by a microwave induction controller IC1 in the microwave induction and detection circuit is TX982. The monostability time-delay circuit is composed of a time-base circuit IC2, a resistor R1 and an electrolytic capacitor C1, wherein the model number adopted by the time-base circuit IC2 is NE555. The status induction circuit is composed of a light-emitting diode (LED) and a resistor R2. All monitor devices can be divided into active detection and passive detection according to starting modes. The inductive type human body approach warning controller is a detection device using the active detection mode, is designed to overcome and compensate certain defects existing in certain monitoring devices, and solves the problem that selling price of all kinds of monitoring devices in market is high at the same time.

Description

technical field [0001] The invention belongs to the technical field of electronics and power-saving control, and relates to an inductive human body approach alarm controller. Background technique [0002] There are many types of alarms used for monitoring in the market, and the main ways to obtain alarm information are: first, the alarm with the largest market share, which uses an infrared sensor with a pyroelectric effect device and a Fresnel lens as the probe; The most representative is the anti-vibration, anti-prying, and anti-noise alarms made of vibration and displacement sensors; the third is a small number of alarms made of touch, induction probes, and microwave probes. The leading position and active role of these burglar alarms in many areas of prevention should be affirmed, but they do have some problems in actual use. For example: when the ambient temperature is high, installing and using the human body pyrolysis infrared monitoring device outdoors in summer does...
