The central processing unit is also associated with alarm module.
In the present invention, several described vibrating sensors are separately positioned on the portion for needing to be detected on agricultural machinery
Position, such as engine, gearbox, transmission shaft, differential mechanism position, obtained real-time Vibration Condition information.
As shown in Fig. 2, the operation principle of the utility model is：Multiple vibrating sensors acquire different components on agricultural machinery respectively
Vibration information, the vibration signal that vibrating sensor will be perceived（Including acceleration, displacement）, put by charge amplifier
Greatly, analog electric signal is obtained, the analog electric signal of gained can pass to the microcontroller being respectively correspondingly connected with, i.e. data are adopted
Truck, the analog electric signal that microcontroller will come transmitted by vibrating sensor show that set of number is believed by conversion process
Number, this group of digital signal is passed to central processing unit by microcontroller again, and central processing unit can be according to the working condition of agricultural machinery（Turn
Speed and load）After selecting, the digital signal of perception gained and bottom are vibrated for the bottom data type compared required for determining
Frequency spectrum data is compared, and the result obtained is same degree of shaking, and corresponding visual by display module and storage module progress
Change display and record, when same degree of shaking is then normal to be considered as in the range of setting, whole system continues to run with, if the data obtained is super
The range of setting is crossed, alarm module will start.
Central processing unit is preset with bottom rumble spectrum, bottom rumble spectrum set process as：It is adopted by vibrating sensor
Collect bottom rumble spectrum figure of the agricultural equipment under different rotating speeds and different load, the principle vibrated using multifrequency chooses agricultural machinery
The rumble spectrum of different operating modes under optimum Working is bottom, and classification is set, and Planning goes out best bottom spectrogram.
