Vehicle-mounted GPS automatic alarm equipment

Abstract

The invention discloses vehicle-mounted GPS automatic alarm equipment, which comprises a cloud map information acquisition unit, a control core, an early warning unit, a wireless transceiving unit, aposition judgment unit and a measurement and calculation unit, and relates to the technical field of vehicle-mounted GPS equipment. In the vehicle-mounted GPS automatic alarm equipment, a position judgment module judges whether the vehicle is on an expressway, a provincial lane and a national lane or not; if yes, the control core starts the measurement and calculation unit and calculates movementspeed, when the quick-freezing measurement and calculation unit is moved to measure and calculate the speed for a period of time, an exception confirmation module confirms that exception occurs; an alarm information output module in the alarm unit controls a voice alarm module to give an alarm; and when the driver has an accident and does not respond, the traffic police bureau telephone to which the current road section belongs is quickly dialed through the wireless transceiving unit to give an alarm, so that accidents such as subsequent collision and the like caused by the fact that the vehicle is parked on the expressway and the national road can be prevented.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted GPS devices, in particular to a vehicle-mounted GPS automatic alarm device. Background technique [0002] GPS is the abbreviation of Global Positioning System, also known as Global Satellite Positioning System, which is a medium-distance circular orbit satellite navigation system. Military users located anywhere in the world or in near-Earth space need to continuously and accurately determine the three-dimensional position, three-dimensional motion and time. The system includes 24 GPS satellites in space; one master control station on the ground, three data injection stations and With 5 monitoring stations and GPS receivers as the user terminal, at least 3 of the satellites are needed to quickly determine the location and altitude of the user terminal on the earth; the more satellites that can be connected, the more decoded The location of the vehicle is more accurate. When a GPS position...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a vehicle-mounted GPS automatic alarm device, which solves the problem that when a vehicle fails on a road with fewer vehicles, such as an expressway or a national highway, the vehicle cannot be quickly stopped when the vehicle stops on the expressway or the national highway. When the vehicle is moved away, when the subsequent vehicles come and go, because of the high speed, collisions are likely to occur, resulting in accidents. The existing car GPS does not have a good means of alarming
