Abstract

The invention discloses a positioning system based on a laser beam-to-ray detector array, and relates to the application field of the Internet of Things. The sensors and their arrays deployed in the environment include multiple laser beam detectors composed of transmitters and receivers. The transmitters and receivers of multiple laser beam detectors are placed opposite to each other at equal distances. Multiple laser beam detectors Detectors are laid out in horizontal and vertical directions to form a detector network; among the sensors and their arrays laid out in the environment, the receiving end of the laser beam detector is connected to the signal acquisition circuit, and the signal acquisition circuit is connected to the microcomputer through the SPI serial interface. The processor circuit is connected; the human-machine interface circuit includes a PC computer and an RS485 interface chip connected to each other, and the microprocessor circuit is connected to the PC computer through the RS485 interface chip. The system does not require the person or object to be positioned to hold some kind of positioning device, and is an active positioning technology. And the laser has high reliability and anti-interference characteristics.

Description

technical field [0001] The invention relates to the application field of the Internet of Things, in particular to a positioning system based on a laser beam detector array. Background technique [0002] Positioning technology is the basis for the application of Internet of Things systems such as intelligent security in indoor and outdoor spaces in large public places, smart homes, and smart communities, and has very broad application prospects. [0003] The current common positioning technologies in a specific area are mainly based on Bluetooth, WLAN, ultrasonic, GPS systems, etc. A common feature of these technologies is that they need to have a signal source and a signal receiver. At the same time, these positioning technologies require the person or object to be positioned to hold some kind of positioning device, so they are passive positioning technologies. In order to obtain positioning-related services in such a positioning system, it is necessary to carry a positioni...
