Method, device, storage medium and processor for reading tags

Abstract

The invention discloses a tag reading method, a device, a storage medium and a processor. The method comprises: by solving the minimum distance between the expected value space vector and the observedvalue space vector, the expected value space vector is the space vector composed of idle time slot, non-collision time slot and mathematical expected value of collision time slot in each frame, and the observed value space vector is the space vector composed of the observed value of idle time slot, non-collision time slot and collision time slot actually collected in each frame. Determining the number of time slots in each frame according to the relationship between the frame length of each frame and the number of unread tags; the total unread tag is allocated to each time slot according to the number of time slots for identifying and judging whether the number of unread tags exceeds a threshold value; if the threshold is exceeded, the unread tag is read using a slot random (SR) algorithm. The invention solves the technical problem of low identification efficiency caused by collision tags and empty tags generated in the radio frequency identification process of the prior art.

Description

technical field [0001] The present invention relates to the field of RFID identification, in particular to a tag reading method, device, storage medium and processor. Background technique [0002] With the development of the construction industry, the cost and time control of construction projects is becoming more and more strict. Lower costs and shorter construction periods are the goals pursued by various construction units. Due to the difficulty of construction of steel formwork and wood formwork, construction costs Relatively high, which makes the emerging aluminum formwork have a wide range of application prospects. [0003] In addition to the above advantages, another advantage that is conducive to the widespread popularization of aluminum formwork is that aluminum formwork can be reused repeatedly. With the continuous increase in reuse, the cost of using aluminum formwork will continue to decrease. The use of has brought great cost advantages. [0004] Due to the ph...
