FIG. 2 is a schematic flowchart of a device state monitoring method provided by an embodiment of the present application. As shown in FIG. 2 , a device state monitoring method provided by an embodiment of the present application includes the following steps:

S201: Acquire, from the server, multiple operation indicators corresponding to the operation of the device to be monitored at multiple different times in the first time period, where the multiple operation indicators include digital signals corresponding to various types of sensors and on-site process parameters information;

S202: For each operation index, determine the change trend of the operation index of the equipment to be monitored according to the operation index at multiple different times in the first time period;

S203: Determine the operating state of the device to be monitored in the first time period according to the change trend of each operating index and the operating index threshold of the device to be monitored in each operating index; The operational metric thresholds determined by the operational status of .

The above is a device state monitoring method provided by an embodiment of the present application. In a device state monitoring method provided by an embodiment of the present application, by installing a variety of different types of sensors on the device to be monitored, and collecting signals generated by the device to be monitored at different times when the device to be monitored is running through a variety of different types of sensors, These signals and on-site process parameter information will be stored in the server as operational indicators. In this embodiment of the present application, after acquiring from the server multiple operation indicators corresponding to the operation of the device to be monitored at multiple different times within the first time period, the operation index changes of the device to be monitored are determined for each operation indicator Finally, according to the change trend of each operation index and the operation index threshold of each operation index of the device to be monitored, the operation state of the device to be monitored in the first time period is determined.

In this way, when determining the operating state of the device to be monitored, the present application considers multiple operating indicators of the device, so compared to using a single indicator detection technology, the accuracy of device state monitoring is improved. In addition, when determining the equipment status, it is determined according to the change trend of the equipment's operating indicators within a period of time and the operating index threshold determined according to the operating status within a period of time, and the change trend within a period of time can exclude abnormal situations at individual time points. , and also improve the accuracy of equipment status monitoring.

In addition, the embodiment of the present application obtains a plurality of operation indicators corresponding to the operation of the equipment to be monitored at multiple different times in the first time period by obtaining the signals generated during the operation of the equipment collected in real time. Real-time monitoring of running status. Thereby reducing a lot of manpower and material resources for regular inspection and reducing maintenance costs.

In S201, a communication connection is established between the processor and the server, and the processor obtains, from the server, multiple operation indicators corresponding to the operation of the device to be monitored at multiple different moments in the first time period. In one example, The processor can also display an interface with multiple device identifiers to be monitored and/or there is an input box for the user to input the device identifier to be monitored, the user can select the required device identifier to be monitored in the interface and/or input the device identifier to be monitored in the input box. Monitoring the device identification, after the processor detects the user's operation, the processor obtains, from the server in response to the operation, multiple running indicators corresponding to the running time at multiple different times corresponding to the to-be-monitored device identification.

For example, the user selects and/or inputs the identifier of the device to be monitored as A, and the processor obtains from the server a plurality of operating indicators corresponding to the operating time of the device A at various times.

In S202, the first period of time may be any period of time from the thirtieth day to one hundred and eighty days of operation of the device to be monitored. The processor integrates the data of each operation index according to the operation index data at multiple different moments in the first time period in each operation index, and forms the change trend of the operation index of the equipment to be monitored according to time. . It should be noted that, after data integration of an operation indicator data, a corresponding change trend of an operation indicator is obtained.

For example, the processor performs data integration according to the temperature information data of device A within the fortieth day of operation, and forms the change trend of the operating index corresponding to the temperature information of the device to be monitored according to the temperature information data corresponding to each moment; The vibration information data within the 40th day of operation is integrated, and the change trend of the operation index corresponding to the vibration information of the equipment to be monitored is formed according to the vibration information data corresponding to each moment.

In S203, the second period of time may be any period from the thirtieth day to one hundred and eighty days of the operation of the device to be monitored. In one example, the threshold is determined by the processor according to the operating state of the device to be monitored after the second period of time. For example, under the condition that the operation status of the equipment to be monitored in the 30th to 40th days is normal, according to the operation indicators and change trends corresponding to the ultrasonic signals of the equipment to be monitored in the 30th to 40th days , the operation index threshold corresponding to the ultrasonic signal is obtained as X. It should be noted that the operation index and change trend corresponding to the ultrasonic signal in the above time period are both lower than the operation index threshold X. Similarly, the corresponding operating index threshold may be determined according to other operating indexes and change trends in the above-mentioned time period.

In an example, the processor determines the running state of the device to be monitored in the first time period according to the change trend of each running index and the running index threshold of the device to be monitored in each running index. It should be noted that, since it is necessary to ensure the comprehensiveness and accuracy of equipment status monitoring and reduce the false alarm rate of equipment status, it is necessary to obtain the equipment operating status according to the change trend of multiple operating indicators and the comparison results of corresponding operating indicator thresholds. For example, the processor obtains the ultrasonic signal, temperature information and vibration signal change trend of the equipment to be monitored from the 50th day to the 60th day of operation, as well as their corresponding operating index thresholds. When the change trend is always lower than the corresponding operating index threshold, the operating state of the equipment to be monitored is determined to be healthy; when the ultrasonic signal and vibration signal change trend is always lower than the corresponding operating index threshold, but the temperature information change trend is higher than the operating state When the indicator threshold is reached, the operating state of the equipment to be monitored is determined to be abnormal; when the change trends of the ultrasonic signal, temperature information and vibration signal are all higher than the corresponding operating indicator thresholds, the operating state of the equipment to be monitored is determined to be seriously abnormal.

In an example, the processor displays different colors on the provided interface according to the operating state of the device to be monitored. For example, green represents the normal operating state of the device, yellow represents the abnormal operating state of the device, and red represents the operating state of the device is seriously abnormal.

With the continuous operation of the equipment to be monitored, some operating indicators of the equipment may change due to equipment wear and other environmental factors. The accuracy of the operation index threshold value of the operation index reduces the false alarm rate of the device, and the embodiment of the present application also provides another implementation manner of the device state monitoring method.

As shown in FIG. 3, on the basis of the above embodiment, the following steps may be included after S203:

S301: According to the operating state of the device to be monitored in the first time period and the plurality of operating indicators corresponding to the operation time at multiple different times in the first time period, update the operating indicator thresholds of the device to be monitored in each operating indicator .

In a device state monitoring method provided by an embodiment of the present application, the processor is based on the operating state of the device to be monitored in a first time period and a plurality of corresponding operating times at multiple different times in the first time period Operation index, update the operation index threshold of monitoring equipment in each operation index, so, with the increase of operation index data, the operation index threshold of the equipment to be monitored can judge the equipment status more accurately and reasonably, and reduce the false alarm rate.

In S301, according to the operation state of the device to be monitored in the first time period and the plurality of operation indicators corresponding to the operation time of the device to be monitored, the operation indicator thresholds of each operation indicator of the device to be monitored are updated.

For example, from the 70th day to the 80th day of operation of the equipment to be monitored, when the equipment operation status is normal, and the change trend of the ultrasonic signal and vibration signal is always lower than the corresponding operating index threshold, the original temperature information will run. The index threshold is Z, but there is a value M higher than the original temperature information operation index threshold Z in the temperature information operation index trend in the above time period. Since the equipment operation status in the above time period is normal, in order to reduce the false alarm rate, the operation The indicator threshold is more reasonable. At this time, the temperature information operation indicator threshold is updated to M.

Due to the large amount of data in the multiple operation indicators corresponding to the operation of the equipment to be monitored at multiple times, it is not easy for the user to compare and analyze the status to be monitored according to the data. For the efficiency of real-time monitoring of the state of the device to be monitored, the embodiment of the present application also provides another implementation manner of the device state monitoring method.

As shown in FIG. 4, on the basis of the foregoing embodiment, between S202 and S203, the following steps may be further included:

S401: Display the change trend of different operation indicators of the equipment to be monitored in the form of a chart.

In a device state monitoring method provided by an embodiment of the present application, after determining the change trends of multiple operation indicators of the device to be monitored, the processor displays the change trends of different operation indicators of the device to be monitored in the form of a graph. It intuitively represents the relationship between the changing trends of multiple different operating indicators of the equipment to be monitored, and can customize reasonable and accurate operating indicator thresholds for the equipment according to multiple operating indicators, improving the efficiency of real-time monitoring of the status of the equipment to be monitored.

In S401, the processor displays, in the form of a chart, the changing trends of different operating indicators of the device to be monitored.

In an example, the processor can display the specific values of different operating indicators in the form of a time axis, and can select any period of time and any type of operating indicators for comparison and display on the same page, and can also display the equipment to be monitored within any period of time. The changing trends of many different types of running indicators are compared and displayed in the same graph. For example, according to the time axis, the vibration signal data, temperature information data and equipment load data of the equipment to be monitored can be compared and displayed on the same page within the 60th day of operation, and the vibration signal of the equipment to be monitored within the 60th day of operation can also be displayed. The change trend and the change trend of temperature information are displayed in the same graph.

In an example, after selecting and/or inputting a device identifier, the user may also input a required time parameter, and after detecting the user operation, the processor may respond to the user operation and display the device corresponding to the device identifier at that time. Multiple operation indicators, according to the multiple operation indicators, the corresponding multiple operation index trends can be obtained.

In one example, after the processor displays multiple operating indicators of the device to be monitored on the same page, the user can select the required analysis function and/or statistical function, and the processor responds to the user's operation according to the function selected by the user Appropriate processing of multiple operational indicators. The analysis function may include at least one of frequency domain analysis and time domain analysis, and the statistical function may include comparative statistics on operating index data, for example, statistics on the interval where the vibration information of the equipment to be monitored is mainly located during operation.
