[0002] Existing intelligent sensors, such as programmable controllers, use process-oriented programming modes such as ladder diagrams / function blocks, and adopt a passive polling method to query and control the device status of the terminal control devices. After the status of the terminal devices changes, no status messages are sent outwards. When the superior device / platform needs to obtain the status of the terminal devices, it has to query the corresponding programmable controller, resulting in low working efficiency of the superior device / platform and a large waste of information processing capabilities; in order for the superior device / platform to quickly obtain the working status of the terminal devices, it needs to quickly send out query instructions, which greatly occupies network resources and leads to heavy network loads.

[0027] Figure 2 is a flowchart of the method for active detection and reporting of the working status of the intelligent controller of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use.

[0029] Figure 1 shows the structure of the active detection and reporting system for the working status of the intelligent controller of the present invention. As Figure 1As shown in the figure, the working state active detection and reporting system of the intelligent controller of the present invention is used to detect and report the current state information of one or more terminal devices 60. The system includes: a superior device / service platform 50, an edge gateway 40, and multiple types of intelligent controllers 10, 20, 30.

[0030] The intelligent controllers 10, 20, 30 are used to collect the states of the terminal devices 60 and control the actions of the terminal devices 60; the terminal devices 60 controlled by the intelligent controllers 10, 20, 30 include sensors and execution devices (such as fans, lamps, etc.). Among them,

[0031] The superior device / service platform 50 is used for:

[0032] Obtain multiple types of terminal device models and their model configuration information; send the obtained multiple types of terminal device models and their model configuration information to the edge gateway 40;

[0033] Receive the current state update messages of one or more terminal devices 60 reported by the edge gateway 40, and perform relevant logical processing based on the received current state update messages;

[0034] The model configuration information includes: the operation logic of the terminal device, the time interval for detecting the operation state, control instructions, and query instructions.

[0035] Specifically, the superior device / service platform 50 can obtain multiple types of terminal device models and their model configuration information in different ways, including: (1) On the superior device / service platform 50, the user programs multiple different types of intelligent controllers 10, 20, 30 and the terminal devices 60 controlled by them to establish multiple types of terminal device models and configure the terminal device models; or, (2) Multiple types of terminal device models and their model configuration information are established in advance and stored in the database. The superior device / service platform 50 can obtain the required type of terminal device models and their model configuration information by calling according to needs.

[0036] The edge gateway 40 is used for:

[0037] Receive multiple types of terminal device models and their model configuration information sent by the superior device / service platform 50, establish a terminal device information table corresponding to multiple types of terminal device models, and send the corresponding type of terminal device models and their model configuration information to the corresponding type of intelligent controllers 10, 20, 30;

[0038] Based on the current status update messages of the terminal devices 60 controlled by one or more intelligent controllers 10, 20, 30 actively reported, the edge gateway 40 updates the current status information of these one or more terminal devices 60 in the terminal device information table it manages internally, and reports the current status update messages (including fault messages and working status) of these one or more terminal devices 60 to the upper-level device / service platform 50;

[0039] After receiving multiple types of terminal device models and their model configuration information sent by the upper-level device / service platform 50, the edge gateway 40 can return response information to the upper-level device / service platform 50 to confirm that the data sent by the upper-level device / service platform 50 has been reliably delivered.

[0040] The edge gateway 40 also supports fault detection of the intelligent controllers 10, 20, 30. When one or more intelligent controllers 10, 20, 30 fail, the edge gateway 40 immediately sends alarm information about the failure of these one or more intelligent controllers 10, 20, 30 to the upper-level device / service platform 50.

[0041] The intelligent controllers 10, 20, 30 are used for:

[0042] Save the corresponding type of terminal device model and its model configuration information received from the edge gateway 40, and establish a terminal device status table according to the corresponding type of terminal device model and its model configuration information;

[0043] Query the current status of the terminal devices 60 controlled by it according to the model configuration information. When the current status of the terminal devices 60 controlled by it changes, update the current status data of the terminal devices 60 it controls in the terminal device status table; and send the current status update messages (including fault messages and working status) of the terminal devices 60 controlled by it to the edge gateway 40.

[0044] When the intelligent controllers 10, 20, 30 of the present invention detect that the current working status of the terminal devices 60 controlled by them changes, they update the current status data of the terminal devices 60 controlled by them in the terminal device status table; and actively report the current status update messages of the terminal devices 60 controlled by them to the edge gateway 40. The edge gateway 40 updates the terminal device information table of this terminal device 60 and sends the current status update message of this terminal device to the upper-level device / service platform 50, so that the upper-level device / service platform 50 does not need to poll the current status of this terminal device 60, greatly reducing the communication load of the upper-level device / service platform 50.

[0045] After receiving the corresponding type of end - device models and their model configurations sent by the edge gateway 40, the intelligent controllers 10, 20, and 30 can return response information to the edge gateway 40 to confirm that the data sent by the edge gateway 40 has been reliably delivered.

[0046] The types of the intelligent controllers 10, 20, and 30 include, but are not limited to: programmable controllers 10, serial - port control devices 20, and data collectors 30.

[0047] When the upper - level device / service platform 50 needs to actively query the current status of one or more end - devices 60, it sends a command to the edge gateway 40 to query the current status of the one or more end - devices 60. After receiving the command to query the current status of the one or more end - devices 60, the edge gateway 40 looks up the status values of the one or more end - devices 60 from the end - device information table it manages internally, and sends the current status messages of the one or more end - devices 60 to the upper - level device / service platform 50.

[0048] When the upper - level device / service platform 50 of the present invention performs initialization work, it needs to query the working status of all end - devices 60 to establish a working environment. After receiving the query command, the edge gateway 40 retrieves the current status values of all end - devices 60 from multiple end - device information tables it manages internally and returns them to the upper - level device / service platform 50, reducing the link of querying the working status of end - devices 60 and greatly improving the processing efficiency.

[0059] Step 7, the upper-level device / service platform 50 performs relevant logic processing based on the received status update messages of the one or more terminal devices 60 reported by the edge gateway 40.
