Laser navigation sensor unit without reflective plate and method thereof

Abstract

The invention discloses a laser navigation sensor unit without a reflective plate and a method thereof, belonging to the field of the mechanical and electronic information technology. The unit comprises a laser transmitter, a laser receiver, a wireless sensor and a main controller. The basic method comprises the steps: the laser receiver encodes sensor protocol constraints; the main controller stores encoding and position information; the laser transmitter rotates real-timely to transmit laser signals; the laser receiver receives the signals and wirelessly transmits position information; and the main controller receives and processes the wireless signals. In the unit, a 'angle view' concept is introduced to improve the validity of signals by means of the self-defined encoding method and protocol rules; the position information of the laser transmitter is solved accurately according to the least square method, and the accurate position information is provided to the efficient running of the AGV (Angle View). On the premise of satisfying high-precision requirement, the whole unit is strong in system robustness and high in cost performance and has stronger engineering application value.

Description

technical field [0001] The invention relates to a laser navigation sensor device and method, belonging to the technical field of mechanical and electronic information, in particular to a laser navigation sensor device and method without a reflection plate. Background technique [0002] With the rapid development of the logistics system, the application range of AGV is also expanding. AGV (automated guided vehicle) is an automatic guided vehicle. According to the definition of the American Logistics Association, AGV refers to a transport trolley equipped with electromagnetic or optical automatic guidance devices, capable of driving along a prescribed guidance path, with trolley programming and parking selection devices, safety protection, and various loading functions. The research and development of AGV involves many disciplines such as computer, automatic control, information communication, mechanical design and electronic technology. It is a high-tech integrating light, e...

AI Technical Summary

Problems solved by technology

Among them, the advantages of laser navigation AGV: AGV positioning is accurate; no other positioning facilities are required on the ground; the driving path can be flexible and changeable, and can be suitable for various on-site environments. Restrictive measures such as high cost, technology mastered abroad, technology blockade, etc.

[0010] Laser navigation AGV is the most intelligent and advanced type of AGV. It is used in large quantities in European and American countries. Due to the confidentiality of foreign technologies and high prices, there is no large-scale application in China.
