Background
The electronic tag has wide application field due to the application of radio frequency identification communication technology, relates to logistics and supply management, production manufacturing and assembly, luggage processing and road automatic charging, and also makes great contribution to the application of plastic trays and turnover baskets in storage.
For the current situation that a large amount of electronic tags are put into use, the existing electronic tag communication mechanism cannot well improve the battery utilization rate of the electronic tags, and the service life of the electronic tags is shortened. For storage management, road parking and logistics management applications, the electronic tag plays a great role, in order to save device cost, the electronic tag system in the prior art adopts a public awakening mode for communication, not only is the battery management mechanism of the electronic tag not perfect, but also the service life of the battery is greatly reduced, and the electronic tag does not accord with the environmental protection concept. Meanwhile, if the electronic tag is waken up for many times without purpose, the power supply of the electronic tag is abnormal, and the risk that the electronic tag is in a dead halt state is increased.
For the fields of station parking management, logistics, supply management and the like which relate to the field that electronic tags need to be traded, the electronic tags are waken up and powered up for many times without purpose, so that the electronic tags are easily interfered by human and non-human, and lawless persons are provided with the opportunity of destroying an electronic tag communication system to earn benefits from the electronic tags.
At present, the electronic tag needs to be in a sleep mode when being idle, the working current is less than 20 muA, the awakening sensitivity is extremely low, and the road side unit needs to send a strong signal to awaken the electronic tag. The conventional road side unit sends a radio frequency signal, a radio frequency receiving unit of the electronic tag receives the radio frequency wake-up signal and sends a trigger signal to a main control unit to wake up an internal circuit of the electronic tag, when an individual electronic tag needs to be woken up, the surrounding electronic tags can be woken up by the radio frequency signal at the same time, namely, the surrounding electronic tags which enter a sleep state and do not need to be woken up again are caused to be woken up again, the battery capacity of the surrounding electronic tags is wasted, the service time of a battery is shortened, and the service life of the surrounding electronic tags is also reduced. Meanwhile, the electronic tag is awakened for a plurality of times without purpose, so that the times of awakening and electrifying the electronic tag are increased, and the risk that a management mechanism of the electronic tag is interfered is increased. For the field of road parking and station parking management, a parking meter charging technical means is generally adopted for fixed-point communication, although a certain automatic function is provided for manual operation, the fixed-point communication is complicated, and normally, a car owner needs to operate the parking meter in a self-service manner, purchase a payment card, select a parking space, pay by swiping the card for timing and pay by swiping the card. Therefore, for car owners with poor intuition or car owners who forget to operate the parking meter by themselves, the car owners cannot charge the parking meter, but need to take hard punishment measures to charge the parking meter, and the social contradiction and the inconvenience of subsequent hard charging caused by the hard punishment are obvious. Meanwhile, the parking meter adopts manual card swiping for charging, the height of the parking meter arranged in the charging system is limited, the parking meter is generally limited at the position where a car owner can touch the card swiping, the parking meter is easily damaged by people, and the maintenance cost of the parking meter is greatly increased. For the handset to realize the charging function, the handset is also required to be manually adopted to photograph the vehicle to identify the license plate, or manually input the license plate or the parking space number or swipe the card to start the timing function; and the clock of each handset has errors and can be adjusted manually, so that the timing is inaccurate and serious human intervention problems exist. Electronic tags are not used in large quantities in this field because of their security problems and high cost.

(3) after the electronic tag is awakened, the main control unit controls the wireless data communication unit to send first vehicle related information to the field communication unit, and the field communication unit receives the first vehicle related information and verifies and registers the first vehicle related information.
19. Method of fixed point communication according to claim 16 or 17 or 18, characterized in that said step (6) comprises:
(1) after the second radio frequency communication module sends out a radio frequency wake-up signal, the low-frequency signal transmitting device is controlled by the monitoring management unit to transmit a temporary private wake-up signal;
(2) after the monitoring management unit confirms that the first vehicle related information sent by the electronic tag is not received, inquiring and registering second vehicle related information of the vehicle running out of the low-frequency communication region range;
(3) the electronic tag is awakened after receiving the radio frequency awakening signal and sends first vehicle related information to the fee deduction management unit;
(4) the fee deduction management unit verifies and registers the related information of the first vehicle, meanwhile, the monitoring management unit judges the consistency of the related information of the first vehicle and the related information of the second vehicle, and if the related information of the first vehicle and the related information of the second vehicle are judged to be consistent, the fee deduction management unit is controlled to deduct fees of the electronic tag;
(5) and simultaneously, the electronic tag restores the second awakening matching information into the first awakening matching information to carry out initialization operation.
20. The method of fixed-point communication according to claim 19, wherein the signal that the low-frequency communication geographical area is not occupied by the vehicle can be sent by manual key pressing of the vehicle owner or the inspector through the physical keyboard; or,
and automatically sensing a signal of which the low-frequency communication region range is not occupied by the vehicle through the vehicle sensing device, and reporting the signal to the monitoring management unit.
