This bus information display system is managed by Moxa's V468 x86-based embedded computer. The V468 handles bus timetables, bus routes, and a GPS time synchronization clock for system mapping. Both the V468 embedded computer and buses are equipped with USB Bluetooth for communication. Within 10 meters, the embedded computer can sense which bus is coming via the Bluetooth connection, and displays the real-time information on the panel. If the bus is late, the remote control center can inform the embedded computer over the GPRS modem to notify waiting passengers. Some bus stops may have temperature and humidity sensors (PT-100 protocol) that connect to an ioLogic active Ethernet I/O device and are managed by the embedded computer over the Ethernet LAN. The V468 features 8+8 DI/DOs for controlling station lights. The bus station uses solar energy to charge the V468's 9 to 36 VDC batteries. |
