In this embodiment, the value range of the identification factor may be 0-1.

When the method described in Step1-Step6 is applied, the global identification factor is determined based on the state identification report and the interaction list, and the state identification report and the interaction list can be determined by the first intelligent device and the second intelligent device corresponding to the interactive production data, and when the first intelligent device and the second intelligent device are identified according to the global identification factor, the interactive production data are not directly subjected to characteristic analysis and processing, so that when the interactive production data are overlarge, the state identification report and the interaction list can be analyzed to realize indirect identification of states of different intelligent devices corresponding to the interactive production data, and the time cost can be effectively controlled. Under the working conditions with strict timeliness requirements, the state of the intelligent equipment can be rapidly and accurately identified through the method.

In a more specific embodiment, the determining the device states of the first smart device and the second smart device based on the relative position relationship between the third global identification factor and the first identification interval and the second identification interval described in Step6 further includes the following steps.

When the contents described in Step611-Step613 are applied, the overlapping condition of the first identification interval and the second identification interval can be determined first, so that the device states of the first smart device and the second smart device can be determined according to different overlapping determination results. Therefore, different device states of the first intelligent device and the second intelligent device can be identified based on different relative position relations between the third global identification factor and the first identification interval and between the third global identification factor and the second identification interval, and comprehensiveness of device state identification is improved.

In one possible embodiment, only the first status identification report and the first interaction list of the first smart device sending the interactive production data are obtained in Step2, since the first status identification report and the first interaction list are obtained in a similar manner as the second status identification report and the second interaction list.

Further, the first status identification report of the first smart device may be determined by the following sub-steps.

It will be appreciated that the state identification thread is only started in the following two cases.

(1) And starting the intelligent equipment when the intelligent equipment is in an idle working condition.

(2) The method is started when the identification result sending request of the third party state identification equipment is identified.

It will be appreciated that in both cases, the state identification requires less time-efficiency, which may allow for greater time costs. However, under some working conditions with higher requirements on timeliness, the state identification technology provided by the scheme needs to be adopted.

Accordingly, the device state recognition results in the two cases can be used as the recognition basis of the scheme. Therefore, the historical state recognition result can be directly analyzed, so that the time cost is greatly saved, and the timeliness of equipment state recognition is improved.

In this way, the first state recognition report can be completely and accurately determined based on the plurality of state recognition results.

Optionally, the first interaction list of the first smart device may be specifically determined by the following sub-steps.

Through Step221-Step223, the communication protocol information of the first intelligent device can be analyzed, so that the first interaction list of the first intelligent device can be completely and accurately determined. The first interactive list comprises the object identification information and the interactive time period information of the communication interactive object, and can provide accurate identification basis and data basis for subsequent state identification.

In an alternative embodiment, the determining of the first state identification factor of the first smart device according to the first state identification report and the determining of the second state identification factor of the first smart device according to the first interaction list described in Step3 may specifically include the following sub-steps.

Step312, determining a time weight value of each generation time relative to the state identification duration; wherein the time weight value corresponding to the generation time closer to the current time is larger.

And Step313, determining the proportion of the target state identification result used for representing the abnormal state of the first intelligent device in all the state identification results.

Step314, weighting the time weight value corresponding to each target state identification result according to the occupation ratio to obtain a target weight value; and carrying out weighted summation on the target weight values to obtain a first state identification factor of the first intelligent equipment.

In Step314, the first state identification factor may be understood as a direct state identification factor of the first smart device.

And Step315, determining a target state identification factor of a third intelligent device interacting with the first intelligent device in a state identification time period corresponding to the state identification duration from the first interaction list, wherein the target state identification factor is determined according to the Step corresponding to the first state identification factor.

Step324, weighting the first state identification factor and the second state identification factor by respectively adopting the proportion value and the target proportion value to obtain a first global identification factor of the first intelligent device; wherein a sum of the proportional value and the target proportional value is one.

When the steps described in steps 321 to 324 are applied, the scale values for weighting the first state recognition factor and the second state recognition factor can be determined at the target generation time corresponding to the target state recognition result, taking into account the timeliness of the state recognition of the first smart device.
