Embodiment 1
[0022] Embodiment one: as attached figure 1 As shown, the Beidou vehicle-mounted terminal capable of automatically reading electronic license plates includes a processor module 1, an RFID reader 2, a storage module 3, a Beidou module 4, a GSM module 5, a power supply module 6 and an antenna 10, an RFID reader 2, a storage The module 3, the Beidou module 4, the GSM module 5 and the power supply module 6 are electrically connected to the processor module 1 respectively; the Beidou module 4 and the GSM module 5 are electrically connected to an antenna 10 capable of transmitting and receiving wireless signals. RFID is the abbreviation of Radio Frequency Identification, that is, radio frequency identification technology; compared with traditional magnetic card and IC card technology, it has the characteristics of non-contact, fast reading speed, and no wear and tear. Wireless radio frequency technology performs non-contact two-way data transmission between the reader and the rad...
Embodiment 2
[0030] Embodiment two: as attached figure 2 As shown, a method of using a Beidou vehicle-mounted terminal that can automatically read electronic license plates includes the following steps:
[0031] The first step is to start the power supply module 6, after the fault alarm module 7 and the processor module 1 are initialized in sequence, the RFID reader 2 is initialized and self-checks whether there is any abnormality, and if there is any abnormality, an error message is sent to the fault alarm module 7 and the program is terminated , if there is no abnormality, proceed to the next step;
[0032] In the second step, the processor module 1 sends a reading instruction to the RFID reader 2, and the RFID reader 2 executes the reading instruction, that is, starts to read the vehicle information stored in the RFID electronic license plate and judges whether the vehicle information is read, if not Read and then send error information to fault alarm module 7 and re-execute the...
