Technical Field

The invention belongs to the technical field of application of the Internet of things, and particularly relates to a wheel chock system based on a sensor and an RFID technology and a wheel chock data generation method.

Background

The wheel-up and wheel-down time of the airplane is a key index for measuring the normal rate of flights, and a piece of complete wheel-up and wheel-down data comprises wheel information, flight information, operators, position information and wheel-up (wheel-down) time. The traditional round of data uploading and removing needs manual recording of workers, telephone reporting or handheld device reporting, so that the problems of untimely reporting time, inaccurate recording and even missing recording exist, and extra workload is brought to the workers. The Chinese patent with the application number of 201811543844.5 discloses a system and a method for automatically recording the time of loading and unloading a wheel gear, which comprises a wheel position label arranged on the airport ground and positioned at the position of an airplane tire in a parking space, an airplane electronic wheel gear used for triggering when a wheel gear pull rope is straightened and stressed and identifying the wheel position label, reporting the reported information containing the triggering time and a radio frequency identification result, receiving the reported information of the airplane electronic wheel gear, and a server used for generating the time of loading and unloading the wheel gear according to the triggering time and the radio frequency identification result and recording the time of loading and unloading the wheel gear. The defect is that the information of the operator who moves up and down the gear can not be obtained, and misjudgment is sometimes caused in the judgment of the gear moving up and down.
