Features and exemplary embodiments of various aspects of the invention are described in detail below. The following description covers many specific details in order to provide a However, it will be apparent to those skilled in the art that the present invention may be practiced without some of these details. The following description of the embodiments is merely intended to provide a further understanding of the invention. The present invention is in no way limited to any specific configuration as set forth below, but without departing from the spirit and scope of the invention.

First, the application scenario of the smart device according to the present disclosure will be briefly described below. More specifically, the smart device according to the present disclosure can access various networks, such as 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.

Figure 1 shows a schematic diagram of a star network 100 that a smart device can access in accordance with one 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 acts as the master node. Nodes B, C, D, E, F, and G are all controlled nodes. The master node A can directly control the controlled nodes B, C, D, E, F, G, and the controlled nodes B, C, D, E, F, G can perform corresponding actions according to the control of the master node A. . In the star network 100, the controlled nodes B, C, D, E, F, G may have the same status in the network, but they may receive the same or different control commands from the master node A. Thereby performing the same or different actions.

Figure 2 shows a schematic diagram of a tree network 200 that a smart device can access in accordance with one embodiment of the present invention. A tree network is a hierarchical centralized control network. As shown in Fig. 2, node A is the central node of the tree network and can be used as the master node. Nodes B and C are at different levels from nodes D, E, F, and G. In one aspect, as shown in FIG. 2, nodes B, C may act as controlled nodes with respect to node A, while in another aspect, nodes B, C may be relative to lower-level nodes D, E, F, G. As the master node. Therefore, in FIG. 2, the master node A can directly control the nodes B and C, and the nodes B and C can perform corresponding actions according to the control of the master node A. In addition, the nodes B and C can respectively control the nodes D, E, F, and G, and the nodes D, E, and F, and G can perform corresponding actions according to the control of the nodes B and C, respectively. It should be noted that in Fig. 2, although nodes D, E, F, and G are controlled by nodes B, C, respectively, they may be indirectly controlled by master node A.

Figure 3 shows a schematic diagram of a wireless mesh network 300 that a smart device can access in accordance with one embodiment of the present invention. A wireless mesh network is a wireless multi-hop network. As shown in Figure 3, node A is the central node of the wireless mesh network and can serve as the master node. Nodes B, C, and G can communicate directly with the master node A. Therefore, the master node A Nodes B, C, and G can be directly controlled; nodes D, E, and F can communicate with master node A indirectly through nodes B, C, and G. Thus, master node A can indirectly control nodes D, E, and F. In addition, as shown in FIG. 3, all nodes in the wireless mesh network can communicate directly or indirectly, and control of one node to another node can be implemented in one or more manners, and a fault occurs in a certain node. In this case, an alternative path can be used to achieve control. For example, for node E, master node A can directly control the node via node C, or master node A can pass nodes G and F or G and C (A→G→F→E; A→G→C →E) to control node E, or alternatively, master node A can control node E via nodes G, C, B, and D (A→G→C→B→D→E). Thus, even if the node C fails, the master node A can control the node E by, for example, A→G→F→E.

It should be noted that the above FIG. 1 to FIG. 3 are only examples of application scenarios of the present invention. The application scenario of the present invention is not limited to the network topology shown in the above FIG. 1, FIG. 2, and FIG. 3, and the number of access nodes is not limited to those shown in FIG. 1, FIG. 2, and FIG. The number can be applied to any network with any suitable number of nodes. In addition, the smart device according to the present disclosure can be implemented as the controlled node in FIGS. 1 to 3 described above.

A method of implementing an instant state transition of a smart device and a smart device enabling such instant state transition according to the present disclosure will be specifically described below.

Figure 4 illustrates a flow diagram of a method 400 of implementing an instant change in state of a smart device in accordance with one embodiment of the present invention. As shown in FIG. 4, the method 400 includes: in step 401, repeatedly powering on and off the smart device.

In step 402, the time of each power-on and power-off is counted, wherein the time between power-on and power-off needs to meet the preset time condition.

In step 403, each time the smart device is powered on, the number of previous power-on and power-off times is determined, and the smart device performs a corresponding action according to the previously executed power-on and power-off times.

In the present disclosure, the smart device is powered on first, and then after the time that meets the preset time condition, the smart device is powered off (ie, powered down), so that the power-on and power-off are called once. Power up and down once. It should be understood that although the power is turned on and off each time in the present disclosure, those skilled in the art should understand that after the smart device is powered on, the number of times of powering up and down each time can be counted first.

In the present disclosure, the time between powering up the smart device and the smart device to powering down needs to meet the preset time condition. In one embodiment, the preset time condition may be that the time between each power-on and power-off is less than a preset time threshold, such as less than T1 seconds. In another embodiment, the preset time condition may be that the time between each power-on and power-off is greater than a preset time threshold, for example, greater than T2 seconds. In still another embodiment, the preset time condition may be that the time between each power-on and power-off is within a preset time threshold range, for example, between T3 seconds and T4 seconds. It should be understood that although T1-T4 is used herein to represent time, this is merely an example, and T1-T4 may be any time set as appropriate, and T1-T4 may be the same or different except T4>T3.

In the present disclosure, the smart device performs a corresponding action according to the number of power-on and power-offs that have been performed each time the power is turned on. That is to say, different power-on and power-off times correspond to different actions. For example, the number of times of power-on and power-off N1 corresponds to action A; the number of times of power-on and power-off N2 corresponds to action B, ..., and the number of times of power-on and power-off Nn-1 corresponds to action C. It should be understood that the smart device can be programmed to implement multiple actions corresponding to multiple different times, as desired. In one embodiment, the action to be performed may be that the smart device exits the network. It should be understood that "exiting the network" may include exiting networks of various different topologies such as those shown in Figures 1 through 3, among other things. In another embodiment, the action to be performed may be that the smart device returns to the factory setting state. In still another embodiment, when the smart device includes a lighting device, the action to be performed may be changing the brightness, color or color temperature of the smart lighting device, and the like.

In one embodiment, after the corresponding action is performed, if the preset timing has not expired, the smart device is powered off, and the number of power-on and power-off is increased.

In an embodiment, the method may further include sensing a power supply voltage of the smart device during power-on of the smart device, and after the corresponding action is performed, if the preset voltage is not expired, the power supply voltage is dropped to Below the threshold voltage, the number of power-on and power-off times is increased without the smart device being powered off.

In one embodiment, the method further includes: after the corresponding action is performed, if the preset time period is full, the power-on and power-off times are restored to the initial value. In one embodiment, the initial value can be the minimum value of the counter.

According to the foregoing method 400 for realizing the instantaneous change of the state of the smart device, the state change of the smart device can be implemented simply and instantaneously, and the smart device can be caused to perform different actions according to the number of times of power-on and power-off.

The specific process of the method for realizing the instantaneous change of the state of the smart device in the present disclosure will be described in more detail below with reference to FIG.

Figure 5 illustrates a flow diagram of a method 500 of implementing an instant change in state of a smart device in accordance with one embodiment of the present invention. As shown in FIG. 5, the method 500 for implementing an immediate change in state of a smart device includes steps 501-515. Specifically, in step 501, the smart device is powered on. It should be understood that this step can be omitted when the smart device is already powered.

Next, in step 502, after the smart device is powered on, a counter value indicating the number of previous power-on and power-off times is read from the memory. It should be understood that the memory can be integrated with the smart device or connected to the smart device through a wired or wireless connection. Thereafter, at step 503, a timer is started to begin timing.

Next, in steps 504-509, it is judged which preset value the read counter value is equal to, and an action corresponding to the preset value is performed according to the judgment result. For example, as shown in Fig. 5, it is first determined whether the counter value is equal to the first preset value (N1) (step 504). In one embodiment, the first preset value N1 may be the initial value of the counter, ie the minimum value. If the counter value is equal to the first preset value N1, the process proceeds to step 505 to perform the corresponding action X. If the counter value is not equal to the first preset value N1, the process proceeds to step 506 to determine whether the counter value is equal to the second preset value (N2). Similarly, if the counter value is equal to the second preset value N2, the process proceeds to step 507 to perform the corresponding action Y. If the counter value is not equal to the second preset value, the process proceeds to step 508 to determine whether the counter value is equal to the n-1th preset value (Nn-1). Similarly, if the counter value is equal to the n-1th preset value Nn-1, the process proceeds to step 509 to perform the corresponding action Z.

In the above, only three preset values (N1, N2, and Nn-1) and corresponding actions (X, Y, Z) are described, but it should be understood that fewer or more preset thresholds and phases can be set. The corresponding action is to give the smart device different ability to change state according to actual needs. It should also be understood that these preset thresholds may be pre-cured in the program of the smart device, or may be pre-stored in the memory, or may be pre-set by the third party through communication or the like. It should also be understood that although the above determinations for the respective preset values are sequential, parallel determinations may also be performed for each of the preset values.

In one embodiment, the action (X, Y, Z) to be performed may be that the smart device exits the network or the smart device returns to the factory setting state. In still another embodiment, when the smart device includes a lighting device, the action (X, Y, Z) to be performed may be changing the brightness, color or color temperature of the smart lighting device, and the like. For example, action X will change the illumination device to red, action Y will cause the illumination device to change to green, and action Z will cause the illumination device to change to blue.

When an action is performed or when the counter value is determined to be not equal to any of the preset values, the process proceeds to step 510. At step 510, it is determined whether the timer has reached the preset timing T. If the timer has reached the preset timing T, the process proceeds to step 514. At step 514, the counter value is restored to the initial value. As described above, in one embodiment, the initial value of the counter may be equal to the first preset value N1. Then, at step 515, the initial value of the counter recovery is updated to the storage device, and then the process ends.

On the other hand, when it is determined in step 510 that the timer has not reached the preset timing T, the process proceeds to step 511, at which time the smart device is powered off, and then in step 512 the counter value is incremented by one to indicate that the power is turned on and off. carried out. Then at step 513, it is determined whether the incremented counter value has reached the preset maximum counter value Nn. If the incremented counter value is equal to Nn, the process proceeds to step 514 to restore the counter value to the initial value, and then the process proceeds to step 515. If the incremented counter value has not reached the maximum counter value Nn, the process proceeds directly to step 515 to update the counter value to the memory. Then the process ends. It should be understood that after the above process is completed, the smart device can be powered up again to repeat the above process, thereby performing the corresponding action according to the updated counter value.

As described above, according to the foregoing method 500 for realizing the state change of the smart device, the smart device can be switched to the certain device by controlling the power supply condition of the smart device to repeatedly power on and off the smart device for a specific time and when the number of times of powering on and off meets a specific requirement. A preset state to achieve a change in the state of the smart device.

In the foregoing method 500 for realizing the instantaneous change of the state of the smart device, when the preset timing of the timer has not expired, the smart device is powered off at step 511 to complete the power-on and power-off.

In other embodiments, the smart device may not be powered off at this time, but when the power supply voltage of the smart device falls below a predetermined threshold, the counter value indicating the number of power-on and power-off is directly incremented. In particular, FIG. 6 illustrates a flow chart of a drop-out measurement process 600 in accordance with one embodiment of the present invention. As shown in FIG. 6, during the power-on of the smart device and before the timer reaches the preset timing T, it is sensed whether the supply voltage drops below the threshold voltage (step 601). If the supply voltage drops below the threshold voltage, then at step 602 the counter value is incremented by one and the smart device is not powered down. Then, in steps 603-605, as in steps 513-515 in FIG. 5, the process can then jump to step 502 in FIG. 5 to repeat the above-described flow. According to the method provided in this embodiment, it is possible to effectively improve the short circuit of the smart device due to the large capacitance value of the smart device, thereby causing the trigger switching state to be slow, so that the device can also perform normal switching when the device is powered on and off quickly. equipment status.
