Description

Technical field [0001] The invention relates to an intelligent microwave induction system, in particular to a microwave sensor (Microwave Det) that can break through the barriers of glass, cement, wood and other building materials to sense the movement of objects in a specific range of three-dimensional space It is an intelligent microwave induction system for controlling the triggering of passive electrical devices, and according to the detected signals, for remote synchronous operation. Background technique [0002] Currently, the commonly used sensing systems on the market mainly use an active infrared device, including an infrared transmitter and an infrared sensor to detect the movement of objects in a specific range. The detection method is to sense the movement of the object through the infrared beam emitted by the infrared transmitter itself. When the surrounding moving objects touch the infrared beam emitted by the infrared sensor, the infrared beam is shielded and canno...

AI Technical Summary

Problems solved by technology

[0003] However, the usual constructions as described above imply a number of manufacturing and usage disadvantages:

[0004] 1. The detection range of the active infrared device is limited to a straight line and cannot cover the entire space

[0005] 2. The active infrared device needs to be equipped with an infrared emitter and an infrared sensor at both ends of a space for cooperation. The equipment and lines are often too long to be concentrated.

[0008] However, although the above-mentioned common structure can improve the situation that the aforementioned active infrared device can only detect in a straight line and cannot cover the entire space, its structure still has many manufacturing and use disadvantages:

[0009] 1. When the heat source on the surface of the object detected by the passive infrared sensor is transmitted to the passive infrared sensor, if the surrounding atmospheric conditions are not good, such as rain, mist, water vapor or near an unstable heat source, the passive infrared ray will The detection sensitivity of the sensor will be seriously disturbed and misjudgment will easily occur

[0010] 2. The passive infrared sensor is susceptible to interference from the external natural environment. Although its detection range can be expanded to three-dimensional space, it cannot break through the barriers of building materials such as glass, cement, and wood, so that its detection range can only be limited to specific indoor spaces. greatly reduces its usefulness

[0011] 3. The passive infrared sensor only detects the surface of objects with heat sources, and cannot detect objects without heat sources
