Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
The structural representation of the vehicle wheel speed measurement apparatus that Fig. 1 provides for this utility model one embodiment.
Reference Fig. 1, a kind of vehicle wheel speed measurement apparatus that this utility model one embodiment provides, including: it is used for measuring car
The micro-mechanical gyroscope 12 (MEMS gyroscope) of angular speed of wheel, radio communication device 13 and for for described micromechanics top
Power supply 11, described micro-mechanical gyroscope 12 that spiral shell instrument 12 and described radio communication device 13 are powered are the microcomputer at least including two axles
Tool gyroscope；
Described micro-mechanical gyroscope 12 is connected with described radio communication device 13, described power supply 11 and described micromechanical gyro
Instrument 12 and described radio communication device 13 connect.
It is understood that this utility model embodiment can first pass through micro-mechanical gyroscope 12 measures angular speed of wheel, then
Angular speed of wheel is transferred to described radio communication device 13, and radio communication device 13 can with the radio communication device of host computer even
Connecing, angular speed of wheel is transferred to the radio communication device of host computer, the radio communication device of host computer is again by angular speed of wheel
The computing unit being transferred to host computer calculates, and then calculates wheel of vehicle rotating speed, finally according to wheel of vehicle tachometer
Calculate car speed.Host computer is the most not shown.
This utility model embodiment can directly be measured the angular velocity mode of wheel by micro-mechanical gyroscope 12 and measure vehicle
Vehicle wheel rotational speed so that obtain vehicle speed.This utility model embodiment is due to only one of which measurement apparatus, it is not necessary to other
Part conjunction measuring, therefore solves the problem installing inconvenience, by using the communication solution of radio communication device 13
The problem that wire communication of having determined is inconvenient.
