Comprehensively considering such problems that the highly cost to guide the whole journey with icons, the partly guidance is not clearly expressed and the twice car navigational tracking is hardly to achieve, the program which transmit data to mobile equipment via the Internet of things to realize the whole navigation is designed. The system includes hardware, software, collects parking data for PC and uses Base Station number segment identification technology transmitting the data to drivers' phone, so the driver can do the whole navigation in the parking lot and take his car when they are back with the data. According to the hardware, software and debug experiment, data can be sent to drivers' phone reliably and the driver can link to Baidu map with the data to achieve location, navigation and twice car navigational tracking in the parking lot easier. This system can be embedded into every parking lot system in any city easily. So it has wide application potential.
