Forklift location monitoring method based on RFID

Abstract

The invention discloses a forklift location monitoring method based on RFID. Forklift RFID tags are arranged on forklifts in a one-to-one correspondence mode, and an RFID reader-writer is arranged in a plant area to collect information of all the forklift RFID tags. During work, integrity verification is conducted on the collected information, and positions of the forklift RFID tags in the plant area are calculated after incomplete data of the collected information are filtered out; the positions of the forklift RFID tags are then marked on a map of the plant area. Abnormal data are recorded when the forklifts pull out of working areas or residence time exceeds a preset time threshold value, and monitoring personnel is informed of the abnormal data. According to the method, indoor location accuracy is high, the positions of the forklifts can be visually displayed, the forklifts can be prevented from pulling out of the working areas, and demotivation of staff can be avoided.

Description

technical field [0001] The invention relates to the field of forklift monitoring, in particular to an RFID-based forklift positioning monitoring method. Background technique [0002] RFID is the abbreviation of Radio Frequency Identification, that is, radio frequency identification, which is a non-contact automatic identification technology. It automatically identifies the target object through radio frequency signals, and can quickly track items and exchange data. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is fast and convenient. RFID technology was born during World War II. It is the successor of traditional barcode technology, also known as "electronic tag". [0003] In the specific application process of the RFID system, the composition of the RFID system will be different according to di...

Problems solved by technology

[0009] The patent can locate forklifts through GSM module satellite positioning. Since forklifts are generally used indoors, electromagnetic wave shielding makes their accuracy low and cannot meet the needs of many operations.

At the same time, the system cannot remind the decision-maker whether the forklift has crossed its work area according to the state of the forklift, nor can it remind the decision-maker that the forklift operator is passively slowing down
