Description
Technical field
The utility model relates to Big Dipper positioning system and the system combined application of inertia attitude algorithm, belongs to a part for car networking.
Background technology
Big Dipper positioning system more and more obtains promotion and application widely on oversize vehicle, aspect the networking monitoring of vehicle and location, playing more and more important effect, but at some extreme environments, especially when Vehicle Driving Cycle is at high mountain, thick forest, valley, culvert, or travel in the place that has higher buildings thing to stop, often Big Dipper signal can not receive, and causes the malfunctioning situation of simple dependence Big Dipper location assisting navigation; Also have a kind of renewal of situation Big Dipper navigation information not prompt enough, cause navigation data not in time, in the situation that some key crossings need to be known navigation position information especially, can not get on the contrary effective navigation position information.
Inertia attitude algorithm system is the posture monitoring of a kind of course and the system of adjusting based on gyroscope, electronic compass, Gravity accelerometer, it is a kind of navigational system among a small circle, especially along with the development of MEMS gyroscope fibre optic gyroscope, its volume is more and more microminiaturized, and integrate the appearance of the nine multifunctional integrated axle gyro sensors of three kinds of sensors, for new vitality has been injected in the development of inertial navigation system.
Summary of the invention
The present invention is intended to provide the Position Fixing Navigation System of a kind of combination Big Dipper positioning system and inertia attitude algorithm system doubling advantage to address the above problem for travelling at above-mentioned extreme environment vehicle.The utility model adopts ARM M3 series monolithic and DSP digital signal processor, can be arranged on and travel on the vehicle of extreme environment.
The utility model adopts following technical scheme:
Comprise following nextport hardware component NextPort: DSP data processor, MCU micro-control unit, nine axle gyroscope acceleration magnetometer sensors, the Big Dipper 2 generation locating module, data memory module, display screen, mobile communication module, voice module, power module.
Described MCU micro-control unit is ARM M3 kernel high-speed low-power-consumption single-chip microcomputer, be connected by bus with other module, be responsible for receiving from the Big Dipper 2 generation locating module the locating information such as latitude, longitude, speed, course that comes from satellite, gather three-axle magnetic field intensity, three axis angular rates, 3-axis acceleration component from nine axle gyroscope acceleration magnetometer sensors, and reportedly pass dsp processor nine numbers, further information is corrected in locating information demonstration, course and offer driver by display screen or voice module.
Described DSP data processor is that special digital signal is processed CPU, mainly complete axle gyroscope acceleration magnetometer sensor collection three-axle magnetic field intensity, three axis angular rates, the 3-axis acceleration component that measurement is returned to MCU and carry out filtering algorithm analysis, to obtain the optimum correction of course, for Big Dipper signal do not receive or invalidating signal during the navigation of travelling reference is provided.
The standard that described mobile communication module adopts is GPRS/CDMA.
The beneficial effects of the utility model are:
1,the parameter that the place not receiving at Big Dipper signal relies on nine axle gyroscope acceleration magnetometer sensors to provide still can provide lasting homing capability within the specific limits.
2,the location aware information timely and effectively at the crossing of running at high speed, overcomes the Big Dipper and upgrades travelling of causing not in time and exceed phenomenon.
