Problems solved by technology

Although RFID has high positioning accuracy, since RFID needs to be identified by induction to achieve positioning, it can only be applied to short-distance positioning, so its application range is greatly limited.
Furthermore, in precise positioning, whether it is RFID or other technologies, its power consumption is relatively high, and energy saving cannot be achieved.

Abstract

The invention provides an optical signal positioning device, a method and a system and belongs to the photoelectric signal technology field. The device comprises an optical signal sending module and an optical signal processing module. The optical signal sending module and the optical signal processing module form optical coupling. The optical signal sending module is installed on an object to bemeasured. The optical signal sending module is used for determining whether the moving speed of the object to be measured satisfies a preset condition. If the moving speed of the object to be measuredsatisfies the preset condition, through positioning a light source, positioning light is emitted, and through at least two light sources, flare light is emitted. The optical signal processing moduleis used for acquiring the positioning information of the object to be measured according to the collected poisoning light and determining the position change condition of the object to be measured according to the at least two paths of collected flare light and the positioning information. The optical signal sending module emits the flare light according to the moving speed so as to realize the control of power consumption. The optical signal processing module collects the flare light sent by the optical signal sending module on the object to be measured so that the object to be measured is accurately identified, positioned and tracked in middle and long distances.

Description

technical field [0001] The present invention relates to the field of photoelectric signal technology, in particular to an optical signal positioning device, method and system. Background technique [0002] With the development and progress of science and technology, the technology of positioning the object to be measured has been widely used in society. [0003] Currently, a GPS-installed object to be measured can be positioned through a GPS (Global Positioning System, Global Positioning System). Although GPS positioning can realize long-distance positioning, there is a technical problem that the positioning is not accurate enough. In addition, at present, RFID (Radio Frequency Identification, radio frequency identification) can also be used to locate the object under test installed with RFID. Although RFID has high positioning accuracy, it can only be applied to short-distance positioning because RFID needs to be identified by induction to achieve positioning, so its appl...
