In, since the fluctuation of water can cause the very big error of gyroscope 16 and acceleration transducer 14, when this example is constructed on the water
Reduce the data using or without using such sensor, also can effectively avoid the wrong vehicle brought because of the data of mistake
State.
As shown in Figure 4 and Figure 5, in step S3 described in this example, each sensor in the detection unit 1 is arranged in advance
Corresponding characteristic coefficient after the processing unit 2 receives information data, is weighed in conjunction with pre-set characteristic coefficient calculating parameter
Weight, so obtain vehicle-state, the vehicle-state include in fired state, flameout state, time, market and longitude and latitude at least
A kind of data.
This example preferably pre-sets different characteristic coefficients to different sensors, is carried out in conjunction with different operative scenarios
The COMPREHENSIVE CALCULATING of a variety of data, and then accurately and effectively fired state and the car status information of flameout state can be obtained, into
And obtain include a variety of data in fired state, flameout state, time, market and longitude and latitude vehicle-state so that acquisition
Vehicle-state accurate and effective.
To sum up, this example 2 work that can individually control each sensor in the detection unit 1 through the processing unit
And power supply, and signal detection setting and data feedback are carried out to sensor, in the case where meeting the enough use of signal data, to the greatest extent
The reduction electrical source consumption of amount, achievees the purpose that power saving, meanwhile, after the processing unit 2 receives the information data of detection unit 1,
It just can judge that vehicle is fired state or flameout state by data analysis, therefore, this example can easily detect vehicle
Fired state and flameout state, docked without the circuit with vehicle, do not have to vehicle on power supply, effectively reducing into
This while, installation are also very convenient；It on this basis, can also be by the multiple interfaces of the output unit 3 vehicle-state
Send, a variety of application platforms and equipment can be docked, vehicle management and vehicle location are inquired etc. play it is crucial and
Effective effect.
The specific implementation mode of the above is the better embodiment of the utility model, and it is new not to limit this practicality with this
The specific implementation range of type, the scope of the utility model includes being not limited to present embodiment, all according to the utility model
Shape, structure made by equivalence changes it is within the protection scope of the present utility model.
