RFID is a non-contact automatic identification technology that automatically identifies target objects and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can be used in harsh environments. The RFID automatic bus stop announcer system consists of a voice module, an infrared module, a temperature and humidity module, a single-chip microcomputer and an RFID module. First, collect and confirm the location information of the bus, and can also measure the temperature and humidity in the car and the number of passengers in the car; thus realize the automation of intelligent station announcement, which not only reduces the work intensity of the driver, but also improves the safety of the vehicle operation. RFID bus automatic stop announcer management realizes paperless bus dispatch.

Utilize RFID technology to provide information collection function for urban bus dispatching system. Realize the automatic, accurate, long-distance, non-stop collection of bus entry and exit information, and realize the paperless bus dispatching, so that the bus dispatch system can accurately grasp the real-time dynamic information of the bus in and out of the bus parking lot, and can also use wireless in time The method of data transmission transmits the driving information to the control center of the bus station in time, and can grasp the driving status of the bus in time. In addition, some important data can be connected to the settlement center through the station dispatch center to exchange data. .
In the current unmanned ticketing vehicle system, the bus station announcement requires the driver to manually control the station announcement button, which often causes false alarms, omissions or even non-reporting, which brings great inconvenience to passengers. Manual stop reporting is of low intelligence and complex buttons. It not only requires the driver to operate the stop reporting device proficiently, but also brings potential risks to the safety of the bus because it is still driving the vehicle. In order to solve this problem, the single-chip microcomputer, voice chip, and RFID module are combined to propose a design scheme for a bus station announcement system. Design and realize the function of automatic bus stop announcer, that is, according to the RFID recognition result, the single-chip microcomputer controls the voice chip to announce the station according to the stored station name, and realizes the automatic station announcement when the bus enters and exits, the intelligent processing of vehicles getting on and off the bus, and sending in the car Air information function, so as to truly realize the intelligence of bus stop announcement.

The overall design plan consists of a voice module, a single-chip microcomputer and an RFID module. The system uses RFID to determine the location of the vehicle, and transmits the signal to the microcontroller through the wireless module, and then the voice module reports the station.

The RFID station identification module realizes the functions of RFID electronic tag identification and acquisition of relevant information at the bus station. Register with the electronic tag of each bus station. Due to the uniqueness of the RFID electronic tag, the system can only identify the station accurately and report the station. Through the identification of the electronic tag code, the station information is obtained, and finally sent to the RFID station reporting module.

After the RFID station announcement module receives the information sent by the bus station, it compares whether the station is a station in the bus route, obtains the relevant station information from the system, and sends a signal to the voice broadcast system after confirmation, and the voice module plays the sound.

The RFID-based intelligent bus station interaction system includes a vehicle end and a platform end. The vehicle end is wirelessly connected to the platform end. The station reader reads the train number information stored in the RFID of the station vehicle, and the vehicle reader reads the platform RFID electronics The station name stored in the tag obtains station information. Using RFID technology, by installing RFID readers on electronic stop signs and installing RFID electronic tags on vehicles, when buses pass the station, the station actively recognizes the bus RFID electronic tag data and transmits it to the control center as basic data for functions such as station reporting .
