Features and exemplary embodiments of various aspects of the invention will be described in detail below. The following description covers numerous specific details in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is only to provide a clearer understanding of the present invention by showing examples of the present invention. The present invention is by no means limited to any specific configuration set forth below, but covers any modifications, substitutions and improvements of related features, structures, operations, etc. without departing from the spirit of the present invention.

The present invention is applicable to various networks, for example, a star network, a tree network, a wireless mesh network, and the like. The star network, the tree network and the wireless mesh network are described below with reference to FIG. 1 , FIG. 2 and FIG. 3 respectively.

FIG. 1 shows a schematic diagram of a star network 100 in which the present invention can be implemented according to an embodiment of the present invention. A star network is a centralized control network. As shown in Figure 1, node A is the central node of the star network and serves as the master control node, and nodes B, C, D, E, F, and G are all controlled nodes. The master control node A can directly control the controlled nodes B, C, D, E, F, and G, and the controlled nodes B, C, D, E, F, and G can perform corresponding actions according to the control of the master control node A . In the star network 100, the positions of the controlled nodes B, C, D, E, F, and G in the network may be the same, but they may receive the same or different control instructions from the master control node A, thereby executing same or different actions.

FIG. 2 shows a schematic diagram of a tree network 200 in which the present invention can be implemented according to an embodiment of the present invention. A tree network is a hierarchical centralized control network. As shown in Figure 2, node A is the central node of the tree network and can be used as the main control node. Nodes B, C and nodes D, E, F, and G are at different levels. On the one hand, as shown in Figure 2, nodes B and C can be controlled nodes relative to node A, while on the other hand, nodes B and C can be controlled nodes relative to the next-level nodes D, E, F and G as the master node. Therefore, in FIG. 2 , master control node A can directly control nodes B and C, and nodes B and C can perform corresponding actions according to the control of master control node A. In addition, nodes B and C can control nodes D, E, F, and G respectively, and nodes D, E, F, and G can perform corresponding actions according to the control of nodes B, C, respectively. It should be noted that in FIG. 2, although nodes D, E, F, and G are controlled by nodes B and C respectively, they are all indirectly controlled by master control node A.

Fig. 4 shows a flowchart 400 of a method for implementing network node control according to an embodiment of the present invention.

As shown in FIG. 4, a method 400 for implementing network node control may include the following steps:

Step 401: The master control node sends the first counter value to the controlled node when the controlled node accesses the network of the master control node, and the first counter value indicates the preset action until the controlled node accesses the network of the master control node the number of times it was executed;

Step 402: the controlled node receives the first counter value sent from the master control node;

Step 403: the master control node sends the counter value updated according to the execution of preset actions to the controlled node at predetermined time intervals;

Step 404: the controlled node receives the updated counter value sent from the master control node;

Step 405: The controlled node compares the received first counter value with the updated counter value, so as to perform corresponding actions according to the comparison result.

In one embodiment, the master control node may send the updated counter value to the controlled node by sending a packet containing the updated counter value to the controlled node.

In an embodiment, there may be multiple controlled nodes, and wherein, the master control node may respectively send the associated updated counter values to the controlled nodes in a unicast manner.

In an embodiment, there may be multiple controlled nodes, and the master control node may send the associated updated counter value to the multiple controlled nodes in a broadcast manner.

In an embodiment, there may be multiple controlled nodes, and the master control node may send the associated updated counter value to the multiple controlled nodes in a multicast manner.

In one embodiment, the preset action may include the operation of releasing the network address and connection of the controlled node.

In one embodiment, the preset action may include an operation of powering on or powering off the controlled node.

According to the method shown in FIG. 4 , network node control can be realized, for example, enabling the network node to perform self-recovery or automatically complete certain preset actions. In addition, the above-mentioned method is simple and efficient, so it is particularly suitable for low-cost equipment.

The method for implementing network node control according to the present invention will be described in more detail below from the sides of the master control node and the controlled node respectively with reference to FIGS. 5-8 .

Fig. 5 shows a flowchart of a method 500 for implementing network node control at the master control node side according to an embodiment of the present invention.

As shown in FIG. 5, a method 500 for implementing network node control at the master control node side according to an embodiment of the present invention may include the following steps:

Step 501: The master control node sends a first counter value to the controlled node when the controlled node accesses the network of the master control node, and the first counter value indicates that until the controlled node accesses the network of the controlled node The number of times the preset action is executed when the network of the master control node is described;

Step 502: The master control node sends a counter value updated according to execution of preset actions to the controlled node at predetermined time intervals.

In this way, since the master node provides the controlled node with the counter value when the controlled node accesses the network of the master node and the updated counter value transmitted at predetermined time intervals, the controlled node will be able to Compare the results to perform the corresponding action.

The method for implementing network node control at the master control node side will be described in more detail below with reference to FIG. 6 .

Fig. 6 shows a flowchart of a method 600 for implementing network node control at the master control node side according to an embodiment of the present invention.

As shown in FIG. 6, in step 601, the master control node is powered on. In step 602, the master control node acquires an initial counter value, and the initial counter value may indicate the number of times the preset action was executed before the last power-off of the master control node. In one embodiment, the initial counter value may be stored in a storage device of the master control node. In one embodiment, the storage device may be a non-volatile storage medium, such as a flash memory. In an embodiment, the preset action may be an operation of releasing the network address and connection of the controlled node, that is, a clearing operation. However, those skilled in the art can foresee that the preset action here may be any possible operation in the Internet of Things, for example, an operation of enabling a device to be powered on or an operation of enabling a device to be powered off. It should be understood that the counter that counts the counter value can be integrated with the master control node or independent of the master control node, and whenever a preset action is performed, an arithmetic operation is performed on the counter value, for example, incrementing or decrementing the counter value .

Next, in step 603, the master control node starts a timer and sets a timing T. The timer can be used by the master control node to count time, so as to then send updated counter values to the controlled nodes at predetermined time intervals, which will be described in detail below. After that, the method continues, once the preset action is executed, the counter value is changed, and the counter value is correspondingly updated to the memory of the master control node, as shown in steps 604-606. Of course, if no preset action is performed, the counter value does not change and is updated. Afterwards, when the master control node finds that the controlled node accesses the network of the master control node, that is, the judgment in step 607 is "Yes", the master control node will indicate the counter value when the controlled node accesses the network of the master control node , that is, the first counter value N1 is sent to the controlled node, as shown in step 608 .

Next, the master control node judges in step 609 whether the timing T expires. If the timing T has not yet expired, the master control node still updates the counter value according to the execution of the preset action, and when the timing T expires, in step 610, the newly updated counter value, that is, the second counter value N2, is sent to to the controlled node. If the master control node determines that the timing T has expired in step 609, the master control node directly sends the latest updated counter value, that is, the second counter value N2, to the controlled node. In one embodiment, the master control node may notify the controlled node of the counter value by including the counter value in a data packet, eg a heartbeat packet. In an embodiment, when the number of controlled nodes may be multiple, the master control node may respectively send the associated counter values to the controlled nodes in a unicast manner. In an embodiment, when the number of controlled nodes may be multiple, the master control node may send the associated counter value to the multiple controlled nodes in a broadcast manner. In an embodiment, when there are multiple controlled nodes, the master control node may send the associated counter value to the multiple controlled nodes in a multicast manner.

In one embodiment, since different controlled nodes may perform different times of preset actions when they access the network of the master control node, the first counter value for different controlled nodes may also be different. In yet another embodiment, the second counter values for different controlled nodes may be different. For example, in unicast mode, if the master control node executes the action of releasing the network address and connection of one of the controlled nodes, then the second counter value for this controlled node will change, while the first counter value for other controlled nodes will change. Second, the counter value may not change. The case of multicast and broadcast is similar to that of unicast.

Next, in step 611 , the master control node resets the timing T for updating the counter value and sending the counter value to the controlled node according to the execution of preset actions at the next time interval.

According to the method described in Figure 6, the active node sends the counter value of the preset action performed when the controlled node accesses the network of the master control node to the controlled node, and sends the latest updated counter to the controlled node at a predetermined time interval value, so that the controlled node takes corresponding actions according to the comparison of these counter values. In addition, as described above, the updated counter value for the controlled node may not change compared with the previous counter value, and the controlled node does not perform any action at this time.

Fig. 7 shows a flowchart of a method 700 for implementing network node control at the controlled node side according to an embodiment of the present invention.

As shown in FIG. 7, a method 700 for implementing network node control on the controlled node side includes the following steps:

Step 701: The controlled node receives a first counter value from the master control node when accessing the network of the master control node, wherein the first counter value indicates that until the controlled node accesses the master control node The number of times the preset action is executed during the node's network;

Step 702: the controlled node receives a counter value updated according to the execution of a preset action from the master control node at predetermined time intervals; and

Step 703: The controlled node compares the first counter value received from the master control node with the updated counter value, so as to perform corresponding actions according to the comparison result.

As such, by receiving from the master node its counter value indicating the number of times preset actions are performed when accessing the network of the master node and the latest updated counter value received at predetermined time intervals, the controlled node can Corresponding actions are taken based on the comparison of these counter values.

The method for implementing network node control at the controlled node side will be described in more detail below with reference to FIG. 8 .

Fig. 8 shows a flowchart of a method 800 for implementing network node control at the controlled node side according to an embodiment of the present invention.

In step 801, the controlled node is powered on, and then accesses the network of the master control node. In step 802, after being powered on, the controlled node may receive the first counter value N1 sent by the master control node at this time indicating the number of times the preset actions are executed. In an embodiment, the first counter value N1 may be stored in a storage device of the controlled node itself. In an embodiment, the first counter value N1 may also be stored in an independent storage device separate from the controlled node.

Afterwards, in step 803, the controlled node receives the updated counter value, ie, the second counter value N2, sent from the master control node at predetermined time intervals. Likewise, the second counter value N2 may also be saved in a storage device of the controlled node itself, or in an independent storage device separate from the controlled node. It should be understood that the second counter value N2 is always updated at different time intervals.

Next, in step 804, the controlled node compares the received counter value N1 with the counter value N2, so as to perform corresponding actions according to the comparison result.

In one embodiment, if the counter value N1 is equal to the counter value N2, the controlled node performs the first action, otherwise, the controlled node performs the second action, as shown in steps 805 and 806 respectively. In one embodiment, the first action may be that the controlled node does not perform any action. In one embodiment, the second action may be that the controlled node exits the network of the master control node. In another embodiment, the second action may be that the controlled node exits the network of the master control node and restores factory settings. In yet another embodiment, the second action can be that the controlled node changes its operating state, for example, when the controlled node is a lighting device such as an LED lamp or contains such a lighting device, the lighting device can switch its lighting color at this time Or adjust its lighting brightness.

In an embodiment, the controlled node may also perform different actions according to the difference between the received counter value N1 and the counter value N2. In the example of the LED light mentioned above, if the difference is within the first difference range, the LED light can switch to the first color, for example, red, and when the difference is within the second difference range, The LED light can be switched to a second color, eg green. However, it should be understood that more ranges can be set for the difference, in order to finer tune adjustments such as the color and brightness of the lighting device, for example.

As such, by receiving from the master node its counter value indicating the number of times preset actions are performed when accessing the network of the master node and the latest updated counter value received at predetermined time intervals, the controlled node can Corresponding actions are taken based on the comparison of these counter values. It should be noted that the predetermined time interval at which the controlled node receives the updated counter value actually depends on the predetermined time interval at which the master control node sends the updated counter value to the controlled node. It should be understood that the predetermined time interval is not specifically limited, but those skilled in the art can set an appropriate specific predetermined time interval according to the teaching of the present invention.

As above, the method for implementing network node control according to the present invention is described. According to the invention of the present invention, the network node can be made to perform self-recovery or automatically complete certain preset actions. In addition, the method proposed by the present invention is simple and efficient, and thus is particularly suitable for low-cost equipment.
