Embodiment
Below by drawings and Examples, the utility model is further elaborated.
As shown in Figure 1: a kind of motor vehicle running accident automatic alarm system, comprise GPS receiver module 1, processor 2, gsm communication module 3 and the sensor assembly 4 for collection vehicle attitude information data, GPS receiver module 1 is connected with processor 2 respectively with sensor assembly 4, and processor 2 is connected with gsm communication module 3.
Sensor assembly 4 comprises the accelerometer 41 for acceleration measurement, the gyroscope 42 for measured angular speed and the magnetometer 43 for taking measurement of an angle.
GPS receiver module 1 adopts and core star leads to UM220 module, its power consumption representative value is 350mw, normally can work, within positioning precision can reach 10m within the scope of-40 DEG C-+85 DEG C, and its data updating rate, reception data type can be set as required and start type, meet system requirements.This module also can directly be communicated with external device by UART interface simultaneously, simplifies system hardware structure design.
Processor 2 adopts MSP430 single-chip microcomputer.Gsm communication module 3 adopts Huawei GTM900-C module, and it supports the AT instruction of standard A T instruction and enhancing, supports short message and speech business, normally can work in the scope of-20 DEG C-+70 DEG C, low in energy consumption, meets system operation requirements.Meanwhile, this module can be communicated with the external world by UART interface, and supports the input and output of 3.0V level, makes it can complete communication with the single-chip microcomputer of MSP430 series more easily.
Gyroscope 42 is by measuring the angular velocity around gyrorotor Z-axis in three-dimensional system of coordinate, and integrable obtains angle.Differentiate that object is in three-dimensional motion state by angle and angular velocity.Accelerometer 41 and gyroscope 42 adopt MPU6050 module, and its inside is integrated with gyroscope 42 and accelerometer 41, directly read measured value from module by I2C agreement.
Magnetometer 43 can be used for test magnetic field intensity and direction, the orientation of positioning equipment, and the principle of magnetometer 43 is similar with compass principle, can measure the angle on current device and all directions four direction.Magnetometer 43 adopts HMC5883L, and its inside comprises three axle magnetoresistive transducers, also can read measurement data by I2C agreement.
In addition, native system also comprises respectively to the power supply 5 of GPS receiver module 1, processor 2, gsm communication module 3 and sensor assembly 4 power supply.
Below set forth emphatically the principle of work of lower the utility model motor vehicle running accident automatic alarm system:
GPS realizes vehicle location: the information that GPS receives has GGA, GSA, the polytypes such as GLL, this procedure Selection receives GGA, GSV, the information of RMC three types, comprise in output information under this Three models and be positioned with validity mark, longitude and latitude, date, time and other abundant informations, can meet system location requirement completely.
Vehicle-posture information gathers: the collection of vehicle-posture information is by gyroscope 42, and accelerometer 41 and magnetometer 43 complete.The MPU6050 adopted in native system its be built-in with gyroscope 42 and accelerometer 41, can directly obtain acceleration and angular velocity, eliminate after drift and error through data processing and can obtain acceleration and angular velocity accurately, coordinate magnetometer 43 to calculate via the fusion of hypercomplex number and Eulerian angle formula afterwards, the angle information of now vehicle can be calculated.
Traffic accident determination methods: adopt acceleration in program, angular velocity and angle combine judgement, reach the object judging that traffic accident occurs in several cases.The acceleration that sensor will gather, angular velocity is transferred to after in single-chip microcomputer, single-chip microcomputer judges accekeration in advance, when exceeding setting value, (threshold value of acceleration sets in advance in single-chip microcomputer, such as 15g) after determine that traffic accident occurs, if acceleration does not reach setting value, continue to judge angular velocity, judge whether angular velocity exceedes setting value (threshold value of angular velocity sets in advance in single-chip microcomputer).Angular velocity can be caused excessive when vehicle generation whipping or rolling, but, jolt and angular velocity also can be caused excessive, so now need the judgement of fit angle size just can avoid judging (threshold value of angle sets in advance in single-chip microcomputer, such as 30 °) by accident.If when magnitude of angular velocity and angle value have exceeded setting value simultaneously, can determine that traffic accident occurs.To sum up, by acceleration, angular velocity, angle combine judgement, can in collision, correct in time in the multiple fortuitous events such as overturnings judgement traffic accident generation.
