Problems solved by technology

The current roadside unit sends a radio frequency signal, and the radio frequency receiving unit of the electronic tag receives the radio frequency wake-up signal and sends a trigger signal to the main control unit to wake up the internal circuit of the electronic tag. When it is necessary to wake up individual electronic tags, the surrounding electronic tags will also At the same time, it is awakened by the radio frequency signal, that is, the surrounding electronic tags that have entered a dormant state and do not need to be awakened are awakened again, which wastes the battery capacity of the surrounding electronic tags, shortens the battery life, and also reduces the service life of the surrounding electronic tags. reduce
At the same time, multiple wake-ups for no purpose increase the number of wake-ups and power-ups of electronic tags, which increases the risk of interference with its management mechanism
For the field of road parking and station parking management, the technical means of meter charging is generally used for fixed-point communication. Although it has certain automatic functions compared with manual operation, it is also relatively cumbersome. Under normal circumstances, the owner needs to operate the meter by himself. , buy a payment card, choose the parking space by yourself, swipe the card to count the time, and swipe the card to pay the fee
Therefore, for car owners with poor self-consciousness or car owners who forget to self-operate the meter, they cannot collect fees, but take rigid punishment measures to collect fees. The social conflicts and inconvenience of subsequent rigid fees are also obvious.
At the same time, if the meter is charged by manual card swiping, the height of the meter arranged in the charging system will be limited. Generally, the height is limited to the position where the car owner can touch the card, and the meter is easy to be destroyed, and its maintenance cost is also high. will increase a lot
For the charging function of the handheld device, it is also necessary to artificially use the handheld device to take pictures of the vehicle to identify the license plate or artificially input the license plate or parking space number or swipe the card to start the timing function; and the clock of each handheld device will have errors and can be adjusted manually. , so the timing is not accurate, and there is also a serious problem of human intervention
Due to the security problems of electronic tags and the high cost, electronic tags have not been widely used in this field

Abstract

The invention provides a radio frequency identification (RFID), communication system and method having a fixed-point communication function. The RFID comprises a wireless awakening unit and a low frequency awakening antenna. The wireless awakening unit comprises a comparison unit and a storage unit which is provided with awakening matching information. The wireless awakening unit receives a low frequency awakening signal through the low frequency awakening antenna. The comparison unit compares the consistency of the low frequency awakening signal and the awakening matching information so as to obtain matching information and non-matching information. Based on the matching information, a main control unit sends a trigger signal so as to awaken the corresponding RFID to perform a fixed-point communication. Through the RFID, the communication system and the method of the invention, the problem that a plurality of RFID groups are awakened is effectively solved; the service life of the cell is effectively increased; the service life of the FRID is prolonged; the risk of interfering the FRID is reduced; and protection mechanism for preventing the FRID from interference is further improved.

Description

technical field [0001] The present invention relates to the field of electronic non-parking toll collection, storage management, parking lot, etc., and specifically relates to an electronic tag, a communication system and a communication method including the electronic tag. Background technique [0002] Due to the application of radio frequency identification communication technology, electronic tags have a wide range of applications based on this feature, involving logistics and supply management, manufacturing and assembly, luggage handling and automatic road toll collection, as well as the application of plastic pallets and turnover baskets in storage made a great contribution. [0003] For the current situation that a large number of electronic tags are put into use, the existing electronic tag communication mechanism can not improve the battery usage rate of the electronic tags very well, and shorten the service life of the electronic tags. For warehouse management, ro...
