A device for performance testing of rfid chips

Abstract

An RFID (radio frequency identification) chip performance test device is characterized by comprising an air cannon (1); the mouth of the air cannon (1) is connected with a barrel (2); the air cannon (1) and the barrel (2) are arranged on a support (3); two sides of the barrel (2) are provided with speed sensors (4) which can sense the speed of movement of an RFID chip in the barrel (2); the read-write performance of the RFID chip at a high speed in the barrel can be captured by a read-write device (5). Shot launched by the air cannon of the test device disclosed by the invention is high in speed, and can reach 180km / h or higher speed, and thus, the shot can well simulate a high speed moving object such as a car running on a highway; meanwhile, the air cannon is safe to use, free from gunpowder and pollution-free, and only compressed air is used. No consumables are needed in the use process, and the daily use cost is low. In the whole use process, the site problem can be well solved, and the test cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things control equipment, and in particular relates to a device for testing the performance of an RFID chip, which can test the reading and writing performance of the RFID chip at a speed above 120km / h. Background technique [0002] RFID chips, commonly known as electronic tags, are transponders, or what we call transmitters or transponders. RFID technology was invented in 1969 and a patent was issued in 1973. RFID tags are actually microchips. It is always ready to receive wireless signals from transceivers or RFID readers. After the RFID chip receives a specific wireless signal, it will respond, that is, to send its own unique ID code back to the transceiver. Most RFID chips don't have their own batteries and always start working after a wireless signal wakes them up and asks for a response. [0003] Compared with existing barcode labels, RFID chips have many advantages. First of all, th...

Problems solved by technology

[0004] It is precisely because of the excellent performance of RFID chips that they are widely used, such as in high-speed environments, but the read-write performance of RFID chips in high-speed environments will be limited. Therefore, the read-write performance of RFID chips in high-speed environments has become its performance It is an important sign of good or bad. At present, the reading and writing performance of RFID chips in high-speed environments is basically based on outdoors, using large-scale venues, using cars or similar equipment for testing, but this traditional testing method is generally difficult to reach a speed of 120km / h. h, and the accuracy of the data obtained from the test is not high, and it is impossible to effectively judge the read and write performance of the RFID chip at a speed above 120km / h
