Auto body attitude security protection detecting device
Technical field
The utility model relates to a kind of detecting device, and especially a kind of auto body attitude security protection detecting device specifically is used for the detecting device of automobile security protection and driving safety.
Background technology
Automobile has become the vehicle indispensable in popular life.But along with the increase of vehicle, it is complicated that urban traffic situation becomes, and makes driving safety, and the demand of vehicle anti-theft becomes increasingly conspicuous.Traditional automobile burglar needs to install to 4S, and stolen when vehicle, can not in time notify the car owner, and perhaps vehicle is dragged away and can't be monitored.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of auto body attitude security protection detecting device is provided, and it is simple and compact for structure, can be used for the automobile security protection and detect, and accuracy of detection is high, wide accommodation, and use cost is low, and is safe and reliable.
The technical scheme that provides according to the utility model, described auto body attitude security protection detecting device, comprise the 3 axis MEMS acceleration pick-up for detection of the auto body attitude, described 3 axis MEMS acceleration pick-up is connected with controller, and described controller is connected with wireless communication module.
Described wireless communication module comprises the 3G communication module.Described wireless communication module adopts the UART interface to be connected with controller.
Described 3 axis MEMS acceleration pick-up adopts the I2C Interface and Controler to connect.The power end of described 3 axis MEMS acceleration pick-up, controller and wireless communication module all is connected with power module; Be connected with memory device on controller.
Advantage of the present utility model: detect the vehicle body state by the 3 axis MEMS acceleration pick-up, controller according to the 3 axis MEMS acceleration pick-up judge vehicle stop or the motion in body gesture, to point out accordingly according to corresponding body gesture, can effectively detect the 3 d pose of vehicle, application cost is low, accuracy of data acquisition is high, adopt 3G communication, thereby promptness and the reliability of monitoring and warning have been guaranteed, improve safe driving and vehicle anti-theft warning function, have higher practicality and advance.

Description of reference numerals: 1-3 axis MEMS acceleration pick-up, 2-controller, 3-memory device, 4-wireless communication module and 5-power module.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1: in order to detect the auto body attitude, reach the purpose of automobile security protection and driving safety, the utility model comprises the 3 axis MEMS acceleration pick-up 1 for detection of the auto body attitude, described 3 axis MEMS acceleration pick-up 1 is connected with controller 2, and described controller 2 is connected with wireless communication module 4.
Particularly, 3 axis MEMS (Micro-Electro-Mechanical Systems) acceleration pick-up 1 adopts ADXL345, has ± test area of 16g, and 13 resolution datas that are need not additionally to install other any equipment, and cost is low, and data precision is high.3 axis MEMS acceleration pick-up 1 is installed on automobile, and can be for detection of body gesture.When locked or running state occurs than great fluctuation process when vehicle, controller 2 can send relevant information to the car owner by wireless communication module 4, described information can preset, the car owner judges according to the information that receives whether automobile is in perch, in driving procedure, whether dangerous situation appears perhaps.
Described wireless communication module 4 adopts 3G(3rd-generation, 3G) communication module, described 3G communication module comprises CDMA(Code Division Multiple Access) communication module.Power module 5 provides the working power of 3 axis MEMS acceleration pick-up 1, controller 2 and wireless communication module 4.Be connected with memory device 3 on controller 2, utilize the memory device 3 relevant presupposed informations of storage.Wireless communication module 4 adopts UART(Universal Asynchronous Receiver/Transmitter) Interface and Controler 2 connections, 3 axis MEMS acceleration pick-up 1 utilizes I2C(Inter-Integrated Circuit) Interface and Controler 2 connections.
During use, when vehicle is in flame-out situation, 3 axis MEMS acceleration pick-up 1 is waken up by controller 2 every 1S, and then controller 2 goes to obtain the data of 3 axis MEMS acceleration pick-up 1, by calculating the body gesture of vehicle, judge that vehicle is whether stolen or dragged.When vehicle by falling object from high altitude hit or lawless person pound the car stealing, the vibrations of vehicle body surpass the vibrations threshold values of 3 axis MEMS acceleration pick-up 1, controller 2 can be waken up, and utilizes the built-in wireless communication module of car-mounted terminal 4 to notify the car owner.
In the situation of ignition trigger, the data of controller 2 Real-time Obtaining 3 axis MEMS acceleration pick-ups 1 are obtained body gesture by calculating, and are excessive when the leaning angle of vehicle, point out by LCD and the voice of car-mounted terminal immediately when vehicle; Excessive when the turning speed of vehicle, also can remind driver's assurance safety of slowing down.
The utility model detects the vehicle body state by 3 axis MEMS acceleration pick-up 1, controller 2 according to 3 axis MEMS acceleration pick-up 1 judge vehicle stop or the motion in body gesture, to point out accordingly according to corresponding body gesture, can effectively detect the 3 d pose of vehicle, application cost is low, accuracy of data acquisition is high, adopt 3G communication, thereby promptness and the reliability of monitoring and warning have been guaranteed, improve safe driving and vehicle anti-theft warning function, have higher practicality and advance.
