Example Embodiment
[0055] Examples:
[0056] This embodiment uses the technical scheme of the present invention to construct a bus passenger flow information collection system. The dual-core RFID bus card is used as a citizen public transportation bus card, and a vehicle information collection subsystem is installed on each bus of the bus system. .
[0057] In the system, the dual-core RFID travel card includes a passive RFID tag, a wake-up circuit and an active RFID tag that are electrically connected in sequence. Passive RFID tags are obtained from commercially available mature products. The working frequency of the RFID chip in the passive RFID tags is 13.56MHz and follows the ISO14443 protocol. The active RFID tag is developed and obtained by using the commercially available wireless transmission control chip CC2510 as the core. The CC2510 chip contains an 8-bit MCU (ie 8051), a 2.4GHz radio frequency transceiver (its data transmission and reception rate is 250kbps), and a 32 KB Programmable ...
