Detection system and method and wave beam emitter

Abstract

The invention discloses a detection system and method and a wave beam emitter. The detection method comprises the steps that one or more detection areas are formed in an environment by one or more detection wave beams; the detection wave beams, responded to by one or more detected objects, in the detection areas are received; according to the received detection wave beams, action signals of the detected objects in the environment are obtained; based on the action signals of the detected objects in the environment, action modes of the detected objects in the environment are detected, motion actions and micro-motion actions of the detected objects in the environment can be obtained through the detection method accordingly, and electrical equipment arranged in the environment can be accurately controlled later.

Description

technical field [0001] The invention relates to the detection field, in particular to a detection system, a detection method and a beam transmitter for detecting the action mode of a detected object in the environment. Background technique [0002] An intelligent control system that controls lamps based on user actions is an important means to reduce energy consumption. For example, the intelligent control system can control the way of lighting installed in an environment according to whether a user enters the environment, which is expected to facilitate users and reduce power consumption, so as to achieve the purpose of energy saving and emission reduction. The control process of the intelligent control system in the prior art is: when a detector detects the user's action of entering the environment from the outside, it can generate a control signal to subsequently control the state of the lamp according to the control signal. Although the intelligent control system in the...

Problems solved by technology

Although this intelligent control system of the prior art can bring a certain degree of convenience to users, its defects are also very obvious.

Specifically, the detector of the intelligent control system in the prior art can only detect the movement action of the user in the environment, such as walking action, that is, the large-scale movement action of the user in the environment can be detected by the detector However, tiny movements cannot be detected by the detector of the intelligent control system, which can easily lead to the undesirable phenomenon that the intelligent control system performs misplaced control of the lamp

For example, when the detector detects that the user enters the environment from the outside, the intelligent control system can control the lamps installed in the environment to be turned on. At this time, because the user's movement range is small, the detector cannot detect that the user is in the environment. At this time, the intelligent control system will turn off the lamp for the purpose of saving energy. Obviously, this is not expected by the user. , and once this phenomenon occurs, it will not only cause trouble to the user, but also bring a bad user experience
