Embodiment Construction

[0015] Such as Figure 1 to Figure 3 As shown, the regional logistics movement monitoring and positioning method of the present invention comprises the following steps:

[0016] (1) Set up a dual-frequency RFID tag with two frequencies of low frequency and high frequency. The dual-frequency RFID tag has two transponders and circuits of low frequency and high frequency, and can respond to signals of two types of readers at low frequency and high frequency at the same time. The dual-frequency RFID tag is a dual-frequency single-card RFID tag or a dual-frequency dual-card RFID composite tag;

[0017] (2) Establish a space Cartesian coordinate system with the ground surface in the logistics area (the O-O line in the figure is the ground surface) or a point on a space plane parallel to the ground surface as the origin, and the fixed objects and moving goods in the space of the logistics area The dual-frequency RFID tags are arranged separately on the logistics space, and the dual-...

Abstract

The invention, which relates to a logistics positioning method used in specific areas, discloses a regional logistics moving monitoring positioning method. The positioning method includes the following steps: arranging a double-frequency RFID tag possessing low frequency and high frequency; establishing a space rectangular coordinate system in logistics areas; arranging standard tags (S-Tags) andlocation tags (L-tags); arranging a monitoring robots which comprises a mobile carrying vehicle, two omnidirectional reader and witers which are fixed on the mobile carrying vehicle and share a same central axis, a reading and writing processing system and an emission system; disposing the S-Tags on the fixed constructions or machines in the logistics areas; disposing the L-tags on a mobile logistics pallet or a monitored article; monitoring and analyzing through the monitoring robots; monitoring concrete coordinate figures of the L-tags through defining and making the S-Tags so as to reach monitored positioning of the L-tags.

Description

technical field [0001] The invention relates to a logistics positioning method in a specific area, in particular to a method for precise positioning of logistics and personnel in a factory area by using a dual-frequency RFID card and a mobile monitoring robot. Background technique [0002] Logistics positioning refers to the location of specific items in geographic space. Monitoring and mapping this position to a computer program is one of the important technologies for logistics positioning. At present, the logistics positioning in the macro-geographical space adopts global satellite positioning GPS technology, electronic data exchange (EDI) technology, etc., and its position accuracy is generally within the range of 10 meters, which is obviously not suitable for the logistics positioning of the enterprise's internal factory area; The RFID positioning method used in the factory area usually adopts gate post positioning, global coverage positioning, etc. Gate-post positioni...
