the vehicle-mounted device includes: the method comprises the following steps: the system comprises a low-frequency signal transmitting module, a low-frequency signal receiving module, a signal transceiving module and a microprocessor, wherein the microprocessor is respectively and electrically connected with the low-frequency signal transmitting module, the low-frequency signal receiving module and the signal transceiving module;
the low-frequency signal transmitting module is used for transmitting a first excitation signal in a first preset channel according to a first time period;
after receiving the first excitation signal, the personnel card feeds the authentication information back to the microprocessor through the signal transceiver module in a third preset channel; the authentication information comprises personnel card identification information of the personnel card and holder information of the personnel card;
the bayonet equipment comprises an exciter and a reader-writer, wherein the exciter is also used for sending a second excitation signal according to a first preset channel;
and after the low-frequency signal receiving module of the vehicle-mounted equipment receives the second excitation signal, the collected second preset channel of the authentication information of the personnel card is sent to the card port equipment for authentication under the control of the microprocessor.
The gate device also comprises an authentication module, wherein the authentication module is used for judging whether the authentication information accords with the passing condition; if the authentication information accords with the passing condition, the authentication is successful; otherwise, the authentication is unsuccessful.
The card port equipment further comprises a control module used for opening the entrance guard after the card port equipment successfully authenticates the authentication information.
In the present application, the passing vehicle needs to be equipped with an on-board device, and the on-board device includes a low-frequency signal transmitter as shown in fig. 2, this embodiment may use 125K technology to transmit the first excitation signal, and the first period time may be freely set according to the requirement, for example, one transmission time in 3 minutes.
Each person who enters and exits needs to be equipped with a personnel card in advance, the information of the holder of the personnel card is written into the personnel card, and the identification information of the personnel card and the information of the holder of the personnel 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 personnel card to the vehicle-mounted equipment through 2.4G communication. Since there may be more than one person in a vehicle, authentication information sent by a plurality of person cards may be received on one vehicle-mounted device.
According to the method, the distribution of the passing time of people and vehicles generally accords with the Poisson distribution, the peak value is higher than the average distribution, 1097 vehicles are passed through at 1 hour at the peak of a certain park according to statistics, 1 vehicle is passed through at 3.28 seconds on average, 1276 people are passed through at the peak, 1 person is passed through at 2.82 seconds on average, the vehicle speed is calculated according to 36Km/H (namely 10 m/S), the walking speed of people is calculated according to 6Km/H (namely 1.67 m/S), the diameter range of 100 meters is within 10 vehicles per second, 60 people exist, and the total vehicles are 70 vehicles. If the card access devices receive data at the same frequency and each card within the range of 100 meters transmits data at the same time, the possibility that the reader-writer is blocked is higher.
Therefore, the channel data are attached when the bayonet equipment is arranged to send the second activation code, the bayonet equipment of each lane receives the channel discretization, so that the vehicle-mounted equipment can send the vehicle-mounted equipment and the personnel card number information according to the respective channel data, the vehicle-mounted equipment with at most 3 lanes is excited in the excitation range (<10m), if the vehicle is not excited by 3 vehicles at the same time, the reader-writer cannot be blocked, and if the vehicle is blocked, the vehicle-mounted equipment is properly arranged to wait for a certain random time (the length of a data packet is slot, and the number of the lanes is a random number range) and then send the data.
In this embodiment, sending the second activation code according to the first preset frequency channel allows the vehicle-mounted device to send information according to the second preset frequency channel, so that a blocking situation when the card port device receives the authentication information can be avoided, and data omission and potential blocking caused by receiving the authentication information by the card port device through frequency hopping can also be avoided.
Compared with the prior art that the authentication information sent by the personnel card is passively received, the personnel card in-out 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 immediately replies the authentication information after receiving the first excitation signal, so that the time for the vehicle-mounted equipment to receive the authentication information is greatly shortened, the energy consumption is reduced, and the battery consumption 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 necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
