In this application, vehicle-mounted equipment is required to be installed on a passing vehicle, and the vehicle-mounted equipment is shown in fig. 2 and includes a low-frequency signal transmitter, and the embodiment can adopt 125K technology to transmit the first excitation signal, and the first period time can be freely set according to the requirement, for example, the first period time is transmitted once in 3 minutes.
Each person entering and exiting needs to be provided with a person card in advance, the information of the holder of the person card is written into the person card, and the person card identification information of the person card and the information of the holder of the person card are bound to form authentication information. After receiving the first excitation signal sent by the vehicle-mounted equipment, the personnel card sends the authentication information stored in the first excitation signal to the vehicle-mounted equipment through 2.4G communication. Since there may be more than one person on one vehicle, authentication information transmitted from a plurality of person cards may be received on one vehicle-mounted device.
The method and the device consider that the traffic time distribution of people and vehicles generally accords with poisson distribution, the peak value is higher than average distribution, and according to statistics, the peak value of a certain park passes through 1097 vehicles at 1 hour, the average of 3.28 seconds is 1, the peak value of the peak value passes through 1276 people, the average of 2.82 seconds is 1, the vehicle speed is calculated according to 36Km/H, namely 10m/S, the walking speed of the people is calculated according to 6Km/H, namely 1.67m/S, 10 vehicles exist per second, 60 people exist in a 100-meter diameter range, and the total people and vehicles are 70 people and vehicles. If the bayonet devices are all receiving at the same frequency, each card within the range of 100 meters simultaneously transmits data, so that the possibility that the reader-writer is blocked is high.
Therefore, the invention sets the bayonet device to send the second activation code with channel data, and the bayonet device of each lane receives the discretization of the channel, so that the vehicle-mounted device can send the vehicle-mounted device and personnel card number information according to the respective channel data, and in the excitation range (< 10 m), the vehicle-mounted device of at most 3 lanes is excited, and if the vehicle-mounted device is not excited at the same time, the reader-writer is not blocked, if the vehicle-mounted device is blocked, the vehicle-mounted device is properly set to wait for a certain random time (taking the data packet length as slot and the number of lanes as random number range) and then send.
In this embodiment, the second activation code is sent according to the first preset channel, so that the vehicle-mounted device sends information according to the second preset channel, which can avoid blocking when the bayonet device receives the authentication information, and also can avoid data omission and potential blocking caused by receiving the authentication information by frequency hopping of the bayonet device.
Compared with the passive receiving of the authentication information sent by the personnel card in the prior art, the personnel access management method based on the vehicle-mounted equipment provided by the invention has the advantages that the vehicle-mounted equipment actively sends the first excitation signal according to the first time period, and the personnel card can immediately reply the authentication information after receiving the first excitation signal, so that the time for receiving the authentication information by the vehicle-mounted equipment is greatly reduced, the energy consumption is reduced, and the consumption of a battery is reduced. The battery power is calculated according to 400mAh, the vehicle-mounted equipment consumes 1.21mAh every day, and the service life reaches 329 days.
It should be noted that the above embodiments can be freely combined as needed. The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
