The invention provides a vehicle-mounted navigation system. The vehicle-mounted navigation system comprises a vehicle-mounted GPS (Global Positioning System) antenna, a camera, an AR (Augmented Reality) head-up display and a vehicle-mounted navigation host, wherein the vehicle-mounted GPS antenna is used for locating and obtaining a world coordinate system; the camera is used for carrying out real-time image collection on a road condition ahead; the vehicle-mounted navigation host comprises a coordinate system conversion unit which is used for carrying out image recognition and analysis on a road condition image collected by the camera and converting the world coordinate system to a camera image coordinate system, a model generating unit which is used for generating a 3D (Three-dimension) model of a marching road according to the camera image coordinate system, a virtual navigation information generating unit which is used for generating virtual navigation indicating information according to the 3D model of the marching road and an output unit which is used for outputting the virtual navigation indicating information to the AR head-up display; the AR head-up display is used for projecting the virtual navigation indicating information to a windshield and realizing the effect of overlaying the virtual navigation indicating information to an actual road.

The invention discloses a multi-antenna mobile terminal, which comprises a first machine body, a second machine body, a rotating shaft, a first elastic piece, a second elastic piece, a plurality of radio frequency modules, a first radiator and a second radiator, wherein the first and second machine bodies are connected with each other by the rotating shaft; the first elastic piece and the first radiator are arranged at the first machine body; the second elastic piece, the second radiator and the plurality of radio frequency modules are arranged at the second machine body; at least one of the first radiator, the first elastic piece, the rotating shaft, the second elastic piece, the second radiator and the plurality of radio frequency modules is electrically connected in turn; and the first and second radiators are Bluetooth antennae, wireless fidelity (WIFI) antennae or global positioning system (GPS) antennae. The multi-antenna mobile terminal adopts a way of electrically connecting the elastic pieces and the rotating shaft to ensure radio frequency current between the machine bodies, and adopts the way of connecting a plurality of radiators and the plurality of radio frequency modules to realize the function of multi-antenna and reduce an assembly space to a certain extent.

The invention discloses a multifunctional field infrared camera device. The device comprises a shell front cover, a shell rear cover, an outer box bottom cover, a GPS antenna, a WIFI antenna, a radiofrequency antenna, a COMS circuit board, a first optical lens, a second optical lens, a mainboard, a power panel, a front battery groove, a first lithium battery, a second lithium battery, a battery partition plate, a first solar cell panel, a second solar cell panel and a third solar cell panel. The camera device is provided with a space for installing the solar panel, the lithium batteries and amicrostrip antenna, an independent power panel is installed, and a solar panel assisted lithium battery power supply scheme is supported. The lithium batteries can be repeatedly used, so the camera is more environment-friendly; structures such as a glue stick antenna which is easily damaged are prevented from being mounted outside the camera, and the structure is stable; the single endurance timeof the camera is longer, and the use cost is lower; wireless communication is supported, and the timeliness of data is improved; and a special structure is arranged for accommodating the sensor, so the acquired environmental information is richer.

An antenna device includes an antenna body, a ground terminal, and a feed point. A matching circuit is arranged on the path of the feed point, the feed point is electrically connected to the antenna body via the matching circuit, the ground terminal is electrically connected to the antenna body, and the ground terminal and the feed point are grounded via a printed circuit board. The invention alsoprovides a terminal. The antenna device and the terminal provided by the invention simultaneously realize the functions of the GPS antenna, WiFi-2.4G antenna and the WiFi-5G antenna by arranging a matching circuit at the feed point and can reduce the demand for antenna length.
