Through the process, the purpose that the collected distributed data are combined to monitor the abnormal condition of the oil level through mechanical state data and oil pressure data is achieved, the linkage effect of a plurality of devices such as a mechanical state monitoring device, an oil pressure data collecting device and an oil level abnormal monitoring device is achieved, and therefore the abnormal condition of the oil level can be avoided being reported in a wrong mode or being reported in a missing mode.
As a preferred implementation manner of the embodiment of the present application, as shown in fig. 2, the preset state variance threshold further includes a static state variance threshold, and the step of performing vibration variance processing on the time domain signal segments and comparing the variance value corresponding to each time domain signal segment with the preset state variance threshold respectively to determine the mechanical state according to the comparison result includes the following steps S201 to S202:

Step S202, if the variance value corresponding to the time domain signal segment is smaller than the variance threshold value of the static state and the duration time reaches a first preset time, setting the mechanical state as the static state.
In specific implementation, as shown in fig. 3, assuming that the machine is in an operating state in the last period of time, when the variance value SD corresponding to each time domain signal segment is compared with the preset static state variance threshold value E1, if the currently obtained variance value SD of each time domain signal segment is smaller than the static threshold value E1 and lasts for more than the preset time T1, it indicates that the machine enters a static state from the operating state, and at this time, an oil level abnormal state arming indication is sent to the oil level abnormal monitoring end to perform abnormal oil level monitoring. And after receiving the response of the oil level abnormal monitoring end to the defense deployment indication, the machine enters a defense deployment state, in the state, the oil level abnormal event is continuously monitored, the three-axis sensor is set to be in a trigger state, and once the oil level abnormal monitoring end moves obviously or vibrates, the abnormal vibration event is pushed to give an alarm.

In specific implementation, as shown in fig. 3, assuming that the machine is in a static state in the last period of time, when the variance value SD corresponding to each time domain signal segment is compared with the preset operating state variance threshold value E2, if the currently obtained variance value SD of each time domain signal segment is greater than the static threshold value E2 and lasts for more than the preset time T2, it indicates that the machine enters the operating state from the static state, and at this time, an oil level abnormal state disarming instruction is sent to the oil level abnormal monitoring end to stop monitoring the oil level abnormality. In the disarmed state, the mechanical vehicle is described as being in motion, and the oil level abnormality monitoring may be temporarily stopped at this time.
Alternatively, as shown in fig. 3, when the machine is in a stationary state or is shifted from the stationary state to a moving state in the last period of time, and when the variance value SD corresponding to each current time-domain signal segment is compared with the preset operating state variance threshold value E2, if the variance value SD of each current time-domain signal segment is greater than the stationary threshold value E2 and lasts for more than the preset time T3, at this time, the preset time T3 may be less than the above-mentioned time T2, which indicates that the machine is suspected to enter the operating state from the stationary state, and at this time, the suspected disarming indication of the abnormal oil level state is sent to the abnormal oil level monitoring end. In this suspected disarming state, it indicates that the mechanical vehicle may be in a transition from a stationary state to a moving state or an operating state, and of course, may be subjected to transient vibration caused by external disturbance, and the determination criterion of the oil level abnormality characteristic in this state will be raised.

switch to [ suspected disarmed state ]: and receiving a suspected disarming instruction of the mechanical state monitoring end, and switching to a suspected disarming state.

During specific implementation, if the machine enters a static state, the oil level abnormal state monitoring indication is determined to be sent, namely the machine enters a defense deployment state, the oil level abnormal monitoring end continuously monitors an abnormal event through the three-axis sensor, and once obvious movement or vibration occurs, an abnormal vibration event alarm is pushed, so that whether a request for networking and uploading oil level abnormal data sent by the oil level abnormal monitoring end can be obtained or not is judged through continuous monitoring.
Step S502, if the request for networking and uploading the oil level abnormal data can be received, the mechanical state is set to be a networking state, and the oil level abnormal data are received.
During specific implementation, if an indication that the oil level abnormal data are uploaded and networked by an abnormal monitoring end is received, the machine enters a networking state, and the oil level abnormal monitoring data are networked and received.
And step S503, if the machine state cannot be received, setting the machine state as a disconnected network state.
In specific implementation, if the indication of networking of an abnormal monitoring end and uploading of abnormal oil level data cannot be received within a certain period of time, the mechanical state is kept in a disconnected state. Alternatively, if the machine is in the networking state, when the time for which no data is sent exceeds the preset time T4, the machine enters the disconnection state from the networking state.
