Embodiment Construction

[0046] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] Since the GPS or RFID method is used, it is necessary to install a position detection module composed of a GPS module and an RFID module in the forklift, or to conduct additional network deployment. Therefore, the present invention utilizes the original camera in the warehouse without additional deployment. Through the camera The actual physical position of the target object (referred to as a forklift in this embodiment) can be identified from the collected video pictures.

[0048] UWB positioning technology is a kind of wireless positioning. Popular wireless positioning technologies include GPS positioning, Beidou positioning, Bluetooth positioning, WIFI positioning, RFID positioning, etc. Among them, GPS and Beidou positioning are mainly used for outdoor positioning, and Bluetooth positioning, WIFI positioning, RFID positioning, UWB ...

Abstract

The invention discloses a UWB and UTC timestamp synchronization combined positioning method and positioning system, based on UTC time correction, an MFCC algorithm is used to synchronize multiple paths of video streams to obtain UTC time with unified frame data, and UWB position information is combined to obtain a conversion matrix between the position of a target object in a picture and the actual physical position of the target object. On the basis of the technology, intelligent monitoring application such as forklift moving tracks, busy line states, action analysis and operation efficiencycan be conducted, a series of indexes with important significance are obtained, unified management and scheduling of managers are facilitated, the use efficiency of forklifts and the work efficiency of workers are effectively improved, idling and slowdown of workers are reduced, and the work efficiency of the workers is improved. And the overall economic output of storage is improved.

Description

technical field [0001] The invention relates to the field of warehouse intelligent management, in particular to a positioning method and a positioning system for synchronizing UWB and UTC time stamps. Background technique [0002] At present, the intelligent management technology of warehouse storage is constantly improving, and the forklift management strategy is getting more and more attention. The real-time location information and running track of forklifts are becoming more and more important for warehouse managers to grasp the overall situation. Through the statistics of forklifts in the storage target area, decision makers can timely grasp the number and operation status of forklifts in each area, facilitate the scheduling of forklifts, and greatly improve the use efficiency of forklifts. [0003] The methods of monitoring the running track of forklifts on the market use modules such as GPS or RFID to detect them. The two methods are as follows: [0004] 1) Realize f...
