Abstract

The invention discloses an electric vehicle positioning device. The electric vehicle positioning device comprises a GPS module, a radio-frequency transmitter module and a power module. The GPS module comprises a GPS receiver, an SIM card, a smart phone terminal, a mobile communication data receiving and sending module and a short message receiving and sending module. The radio-frequency transmitter module comprises a radio-frequency signal source. The GPS module and the smart phone terminal are in wireless signal connection through the mobile communication data receiving and sending module. A signal emitted by the radio-frequency signal source is received by a handheld detector. The handheld detector is a yagi antenna. An emergency power supply and a charger module are further arranged in the power module. The electric vehicle positioning device is simple in structure and low in cost, by the adoption of the combined positioning technology of GPS positioning and radio-frequency positioning, the positioning accuracy is high, the mounting location cannot be affected by buildings and weather, and the vertical orientation of the radio-frequency signal source can be determined.

Description

technical field [0001] The invention relates to the field of anti-theft vehicle accessories, in particular to an electric vehicle positioning device. Background technique [0002] China is the world's largest producer and consumer of electric vehicles. At present, the annual production and sales volume of the Chinese market exceeds 40 million vehicles, more than 1,500 vehicle manufacturers, 150,000 dealers, and 160 million vehicles in the market.
