When the path identification card writing device and the path identification card reading device are powered on, after necessary initialization, a "beep" sound is issued, indicating that the path identification card writing device and the path identification card reading device are The device is already waiting to receive work. When the path identification card is swiped on the path identification card writing device and the path identification card reading device, the path identification card writing device and the path identification card reading device detect the swiping of the path identification card, Trigger the path identification card to enter the working state, and the path identification card sends the first set of data, which is used as contact information and useful data.

At this time, the described path identification card writing device and the path identification card reading device will keep the communication connection with the path identification card on the one hand, and keep the communication with the PC computer on the other hand. Communication links, and data is forwarded in real time, so bilateral communications must be strictly synchronized. In order to shorten the communication time and reduce the power loss of the path identification card, the communication speed takes the fastest communication speed of the path identification card as the communication speed of the whole communication. Depending on the working mode, the processing of the last set of data varies.

When the path identification card is powered on, the path identification card enters an intermittent working state, and the interval time is provided by a low-frequency and low-power clock. The transceiver modules are connected, and the wireless transceiver module transmits and receives signals through the antenna. The carrier detection control module detects whether there is a carrier signal. If there is a carrier signal, the wireless transceiver module continues to receive valid data for several times, then closes the receiving module, and then inputs the valid data into the 8051 Single-chip microcomputer, 8051 single-chip microcomputer evaluates the accuracy of the received data again. After it is accurate, it compares it with the most recently received data. After the current data is saved to the data memory, the 8051 MCU automatically enters the deep sleep state. If the wireless transceiver module does not receive valid data, the wireless transceiver module is also turned off, and the 8051 single-chip microcomputer automatically enters the sleep state. After a few seconds, the internal sleep wake-up control module wakes up the 8051 single-chip microcomputer and starts a new receiving process.

When the electronic road sign is powered on, the 8051 single-chip microcomputer in the main control chip loads the program data from the program data memory and starts to execute the program.
