[0101] Perform unit testing and integration testing according to code units and execution order;

[0102] If the test results of the unit test and the test results of the integration test are both passed, the conversion code is determined based on the writing information.

[0131] Based on digital twin technology, digital twins are displayed synchronously according to the device status physical model and the remote control physical model.

[0133] This application determines the device state object model based on the acquired real-time operating status, and determines the remote control object model based on the control instructions of the sender who subscribes to the device control and the device state object model. Based on the digital twin technology, the digital twin is synchronously displayed according to the device state object model and the remote control object model, which improves the suitability of the digital twin synchronous display.

[0134] The embodiment of the present invention provides a method for synchronously displaying a digital twin of an IoT device's operating status transmitted in real time, and further includes:

[0137] The working principle and beneficial effects of the above technical solution are:

[0138] This application determines the warning information of the Internet of Things equipment and dispatches warning personnel according to the real-time operating status, thereby improving the timeliness of the warning.

[0139] In one embodiment, obtaining early warning information of the IoT device according to the real-time operating status includes:

[0140] According to the real-time operation status, the warning devices to be verified are determined; the warning devices to be verified are: IoT devices for which the IoT platform issues abnormal reminders but has not been checked to see whether the warning conditions have been met;

[0141] Obtaining device information of the warning device to be verified; wherein the device information is: attribute information of the warning device to be verified, such as: device type, number, and location;

[0142] Determine the environmental information acquisition channel based on the device information; the environmental information acquisition channel is: a way to obtain the environmental information of the warning device to be verified, such as: a camera that can capture the warning device to be verified, the operation record of the warning device to be verified, etc.;

[0144] Obtain the to-be-verified warning items of the to-be-verified warning equipment; wherein the to-be-verified warning items are: abnormal states that the to-be-verified warning equipment needs to verify, such as: exhaust fan stops rotating;

[0146] Determine search results according to the search template and the environment variables; wherein the search results are: the warning conditions of the warning items to be verified are searched for and the warning conditions of the warning items to be verified are not searched for;

[0147] According to the search results, the warning information is determined. The warning information is: if the warning condition of the warning item to be verified is searched, the warning information is the warning of the warning item to be verified of the warning device to be verified, otherwise, no warning is issued.

[0148] The working principle and beneficial effects of the above technical solution are:

[0149] When an abnormality occurs in the real-time operating status of an IoT device, it is not necessarily an actual warning situation. For example, the abnormal status caused by shutdown and maintenance does not involve the dispatch of warning personnel. Therefore, this application determines the IoT devices for which the IoT platform has issued a warning but has not been inspected, and determines the environmental information acquisition channel based on the device information of the warning device to be verified. Determine the environmental variables based on the environmental information acquisition channel. Obtain the search template for the warning item to be verified of the warning device to be verified, and determine the search result based on the search template and the environmental variables. If the warning condition of the warning item to be verified is found, the warning information is the warning of the warning item to be verified of the warning device to be verified. Otherwise, no warning is issued, thereby improving the accuracy of the warning.

[0150] In one embodiment, determining the environmental variables of the warning device to be verified according to the environmental information acquisition channel includes:

[0151] Acquire trigger information of the environmental information acquisition channel; wherein the trigger information is: the trigger time and trigger duration of the environmental information acquisition channel;

[0152] According to the trigger information, the channel information of the environmental information acquisition channel is expanded in chronological order to obtain a channel information timeline; wherein the channel information is information obtained by the environmental information acquisition channel, such as: shooting video, and also: maintenance log;

[0153] Obtaining a preset variable acquisition time interval; wherein the preset variable acquisition time interval is manually preset;

[0154] Determine the variable acquisition time node according to the variable acquisition time interval and the channel information time axis; wherein the variable acquisition time node is marked on the channel information time axis, and starting from the starting point of the channel information time axis, a variable acquisition time node is determined every variable acquisition time interval;

[0155] Determine whether the environmental information acquisition channel corresponding to the channel information of the adjacent variable acquisition time node has changed;

[0156] If not, the channel information corresponding to the time node is obtained according to the adjacent variables to determine the environment variables; if the channel has not changed, the environment variables can be obtained by directly comparing the adjacent variables to obtain the channel information corresponding to the time node;

[0157] If so, the channel relationship information of the channel and the channel information corresponding to the adjacent variable acquisition time node are obtained according to the changed environmental information to determine the environmental variables. Among them, if the channel type changes, the environmental variables are determined according to the channel relationship information (correlation information of the channel type, such as: camera A and camera B, the channel changes, but is still related, and another example: camera A and maintenance log, the channel changes, and is not related). When determining the environmental variables according to the channel relationship information, if the channel relationship is related, the channel information corresponding to the variable acquisition time node is converted into a correlation before determining the environmental variables. If it is not related, there is no need to obtain the environmental variables, and the environmental variables are determined according to the next pair of adjacent variable acquisition time nodes.

[0158] The working principle and beneficial effects of the above technical solution are:

[0159] This application expands the information acquired by the environmental information acquisition channel in chronological order according to the trigger time and trigger duration of the environmental information acquisition channel to obtain the channel information timeline. Introduce the variable acquisition time interval to determine the variable acquisition time node on the channel information timeline. Determine whether the environmental information acquisition channel of the channel information corresponding to the adjacent variable acquisition time node has changed, and determine the environmental variables separately according to the different judgment results. While scheduling multiple environmental information acquisition channels to improve the comprehensiveness of environmental information acquisition, it can also obtain environmental variables in a timely and accurate manner, thereby improving the reliability of the basis for early warning judgment.
