Abstract
The invention discloses a vehicle-searching system and belongs to the field of wireless communication. The system comprises a vehicle-mounted positioning device, a moveable receiving device and a terminal device, wherein the vehicle-mounted positioning device comprises a radio frequency communication unit I, a satellite positioning unit, a control unit and a power supply unit; the moveable receiving device comprises a radio frequency communication unit II and a transmission unit I; the terminal device comprises a display unit and a transmission unit II; the satellite positioning unit is used for acquiring position information of the vehicle; the radio frequency communication unit I is used for sending the position information of the vehicle to a space; the radio frequency communication unit II is used for receiving the position information of the vehicle; the transmission unit I is connected with the transmission unit II so as to transmit the position information of the vehicle to the terminal device; the position information of the vehicle is displayed by the display unit. The vehicle-searching system can solve the problem of poor vehicle-searching user experience caused by ultra-short Bluetooth transmission information distance and serious signal attenuation of the present vehicle-searching device.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a car-finding system. Background technique [0002] With the process of economic modernization, living standards are getting higher and higher, and the number of residents' car ownership is increasing day by day. However, it is difficult and time-consuming to find a car when the parking lot is too large, when the light is poor at night, or when it is raining. These are the pain points of many driving users. The existing car-finding devices basically transmit information through Bluetooth. Since the transmission distance of Bluetooth is very short, and the attenuation of the frequency band 2.4GHz where Bluetooth is located is particularly large in space, the user's car-finding experience is poor. Contents of the invention [0003] In order to solve the problem that the existing car-finding equipment has poor car-finding experience due to the very short distance of informat...
