Description

Technical Field

[0001] This invention relates to the field of communication technology, specifically to a method for determining network access and deactivation, a computer device, and a computer-readable storage medium. Background Technology

[0002] Most communications involve network access and de-networking. In some wireless communication products, such as those based on Bluetooth and Wi-Fi, network access and de-networking management is particularly important. If a product is accidentally accessed or de-networked due to some special circumstances, at best some devices may become uncontrollable, and at worst the control unit may be affected, leading to the paralysis of the entire control system.

[0003] Currently, most grid connection and deactivation methods on the market are based on the configuration process. That is, the system performs grid connection and deactivation operations on each device during the system setup. Once the configuration is completed, it can be put into use. When the device cannot be controlled due to grid fluctuations or other reasons, the corresponding maintenance is performed. The final analysis may conclude that the device has been deactivated. At this time, the grid connection is re-entered. The above solution is not stable and reliable, has high maintenance costs, and has a poor user experience. Summary of the Invention

[0004] The primary objective of this invention is to provide a method for determining network access and deactivation that can ensure stable equipment operation and reduce maintenance costs.

[0005] A second objective of the present invention is to provide a computer device for implementing the above-described method for determining network entry and exit.

[0006] A third objective of this invention is to provide a computer-readable storage medium that implements the above-described network entry / exit determination method during runtime.

[0007] To achieve the aforementioned first objective, the present invention provides a method for determining network access and de-network access, comprising the following steps: recording the current power-on / off sequence of the controlled device, wherein the power-on / off sequence is the sequence of the power-off state and power-on state of the controlled device after accessing the network; determining whether the current power-on / off sequence matches a preset power-on / off sequence, and if so, controlling the controlled device to de-network access; wherein the preset power-on / off sequence includes at least two power-on / off cycles, and the duration of the power-off state and the duration of the power-on state in each power-on / off cycle are preset values.

[0008] As can be seen from the above scheme, the present invention, by pre-setting the power outage sequence, can determine that the controlled device meets the de-grid conditions only when the recorded current power outage sequence of the controlled device matches the pre-set power outage sequence. At this time, the controlled device is controlled to de-grid, thereby avoiding the phenomenon of abnormal de-grid of the controlled device due to grid fluctuations, reducing maintenance workload, and making the overall grid entry and exit scheme more stable and reliable.

[0009] A further solution is to determine whether the controlled device has joined other networks within a preset time period if the current power-on / off sequence matches the preset power-on / off sequence. If so, the controlled device information is deleted.

[0010] Therefore, it can be seen that, based on the above-mentioned preset power-on / off sequence, a timeout mechanism is introduced, which can further determine whether the currently controlled equipment needs to be disconnected from the network.

[0011] A further approach is to determine whether the controlled device has joined another network within a preset time period, including whether a heartbeat packet sent by the controlled device has been received.

[0012] A further solution is to update the network access configuration information to the controlled device if the current power-on / off sequence matches the preset power-on / off sequence and the controlled device has not joined other networks within the preset time.

[0013] This demonstrates that the controlled device can be guaranteed to be in a normal network access state.

[0014] A further option is that the duration of the power outage state in at least one power-on / off cycle is different from the duration of the power outage state in another power-on / off cycle; and / or the duration of the power-on state in at least one power-on / off cycle is different from the duration of the power-on state in another power-on / off cycle.

[0015] Therefore, it is evident that the differences in preset power-on and power-off sequences can be further increased, thereby more accurately determining whether the controlled equipment needs to be disconnected from the network.

[0016] A further approach is to record the preset device parameters of the controlled device before recording the current power-on / off sequence of the controlled device; obtain the current device parameters of the controlled device according to the preset time interval, and determine whether the current device parameters are consistent with the preset device parameters. If not, write the preset device parameters into the controlled device.

[0017] Therefore, it can be seen that when the controlled equipment is affected by interference and its parameters change and cannot be controlled, control over the controlled equipment can still be restored by writing the preset equipment parameters into the controlled equipment.

[0018] A further approach is to preset device parameters including the MAC address and network ID of the preset device.

[0019] To achieve the second objective mentioned above, the present invention provides a computer device, including a processor and a memory, wherein the memory stores a computer program, and when the computer program is executed by the processor, it implements the above-mentioned network entry / exit determination method.

[0020] To achieve the third objective mentioned above, the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program implements the above-mentioned network entry / exit judgment method when it is executed. Attached Figure Description

[0021] Figure 1 This is a flowchart of an embodiment of the network entry / exit judgment method of the present invention.

[0022] Figure 2 This is a schematic diagram of the preset power-off timing sequence in an embodiment of the grid entry / exit judgment method of the present invention.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0024] Example of network entry / exit judgment method:

[0025] Devices typically join a network in two ways: active and passive. Active joining involves adding the device to a specified network through its own logic, while passive joining involves adding the controlled device to a specified network through a master control device.

[0026] Device decommissioning from the network can generally be divided into two types: proactive and reactive. Proactive decommissioning refers to the device directly exiting the current network through a preset process. This process usually does not require external communication intervention and directly deletes the device's relevant information. Reactive decommissioning involves the master device interacting with the controlled device to inform the controlled device to exit the corresponding network.

[0027] This invention addresses the issue of abnormal network disconnection. By implementing power-on / off timing, a timeout mechanism, and periodic queries of preset device parameters, it can detect whether a device has abnormally disconnected from the network, reducing maintenance workload. This embodiment is applied to a master control device and a controlled device based on Bluetooth or Wi-Fi. The master control device controls the controlled device to enter or leave the network controlled by the master control device. For example, the master control device can be a network master controller. In a smart lighting network, the master control device can be a lighting controller or a smartphone, and the controlled devices are the various lighting fixtures connected to the network.

[0028] Specifically, the network entry / exit determination method of this embodiment is implemented through a computer program running on the main control device. See [link to relevant documentation]. Figure 1 First, step S1 is executed to record the network access configuration information and preset device parameters of the controlled device. Specifically, when the controlled device successfully joins the network controlled by the master device, the master device will record the network access configuration information and preset device parameters at this time. The network access configuration information indicates the settings required for the controlled device to successfully connect to the network controlled by the master device. That is, the controlled device sets up according to the network access configuration information so that it can connect to the network controlled by the master device. The preset device parameters are used to indicate the status of the preset device. The master device sends instructions to the controlled device according to the preset device parameters to control the controlled device. The preset device parameters include the MAC address and the network ID. The network ID is the identifier of the network joined by the controlled device.

[0029] Continue with step S2 to record the current power-on / off sequence of the controlled device. Specifically, after the controlled device successfully joins the network controlled by the master device, the master device will continuously record the power-on / off status of the controlled device, i.e., the current power-on / off sequence. The current power-on / off sequence is the sequence of the power-off and power-on states of the controlled device after it joins the network.

[0030] Then, step S3 is executed to determine whether the current power-on / off sequence matches the preset power-on / off sequence. The preset power-on / off sequence includes at least two power-on / off cycles, and the duration of the power-off state and the duration of the power-on state in each power-on / off cycle are preset values. See [link to relevant documentation]. Figure 2 The power-on / off sequence in this embodiment includes six power-on / off cycles. The power-on duration of the first power-on / off cycle can differ from the power-off duration of the second power-on / off cycle. When the controlled device experiences a power outage due to unstable power supply, and then regains power after the supply stabilizes, the controlled device will be removed from the network controlled by the master device, resulting in abnormal network disconnection. In this embodiment, the master device compares the recorded current power-on / off sequence with a preset power-on / off sequence. The current power-on / off sequence of the controlled device must satisfy the following conditions: there are six power-on / off cycles, and the power-off duration and power-on duration of each power-on / off cycle must be the same as the preset power-on / off sequence. Only then will the master device determine that the controlled device meets the network disconnection conditions and needs to be disconnected. In other embodiments, the preset power-on / off sequence may also allow the power-off duration within one power-on / off cycle to differ from the power-off duration within another power-on / off cycle.

[0031] If the result of step S3 is yes, it confirms that the current power-on / off sequence matches the preset power-on / off sequence. This eliminates the possibility of power outages and power-on failures caused by unstable power supply, and determines that the controlled device may need to be de-networked. The controlled device enters a pre-de-networking state, and further confirmation is needed regarding whether it needs to be de-networked. Step S11 is then executed to determine whether the controlled device has joined another network within a preset time. Specifically, the master control device can obtain the status flag bit of the controlled device through the protocol layer. The status flag bit has two states: 0 and 1. 0 indicates that the controlled device has joined another network, and 1 indicates that it has not joined another network. Therefore, the status flag bit can be used to determine whether the controlled device has joined another network. If the status flag bit is damaged and cannot be read due to interference such as static electricity, pulses, or surges, a heartbeat packet can be obtained from the controlled device to confirm whether it has joined another network. In this embodiment, if the controlled device joins another network within 5 minutes after satisfying the preset power-on / off sequence, it is determined that the controlled device needs to be de-networked, and step S12 is executed to control the controlled device to de-network. The master control device deletes the controlled device's information, completing the controlled device's de-networking. If step S11 results in no, meaning the controlled device hasn't joined another network within 5 minutes of meeting the above power-on / off sequence, the controlled device needs to return from the pre-de-networking state to the network-joining state. Specifically, step S21 is executed, where the master control device updates the network-joining configuration information to the controlled device. It should be noted that the pre-de-networking state indicates the controlled device may de-network, but it remains in the network-joining state; in this state, the controlled device is still powered on.

[0032] If the result of step S3 is negative, it is determined that the current power-on sequence does not match the preset power-off sequence. This may be due to unstable power supply or other reasons causing the controlled device to power off and on. In this case, the controlled device does not need to be disconnected from the network, and step S4 is executed.

[0033] Then, step S4 is executed to obtain the current device parameters of the controlled device. The current device parameters also include the network ID and MAC address.

[0034] Then, step S5 is executed to determine whether the current device parameters are consistent with the preset device parameters. When the controlled device is interfered with by factors such as static electricity, pulse, or surge during operation, the preset device parameters will change, causing the master control device to be unable to control the controlled device. Therefore, the master control device obtains the current device parameters of the controlled device according to a preset time interval and determines whether the current device parameters are consistent with the preset device parameters saved when the device successfully joined the network. For example, whether the network ID and / or MAC address are consistent. If they are consistent, it means that the controlled device is operating normally. If any parameter in the preset device parameters is inconsistent, step S6 needs to be executed to write the preset device parameters into the controlled device, thereby ensuring that the controlled device keeps the preset device parameters unchanged.
