[0025] To make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other without contradiction.

[0026] An embodiment of the present invention relates to a communication network node control method, which can be applied to a central device. In this embodiment, the central device and multiple peripheral devices form a one-to-many network topology structure, and the method includes: broadcasting a synchronization data packet, the synchronization data packet carries an operation code for indicating the network update type, and the current time slot number of the target peripheral device, the group number of the target time group to be jumped, and the target time slot number; after receiving the response packet of the target peripheral device, sending a response confirmation packet, and updating the network table information, the network table information is used to indicate the occupation of each time slot in each time group by the peripheral device; wherein the position of the peripheral device is determined by the time group group number and the time slot number. By broadcasting a synchronization data packet and carrying an operation code, the time slot number of the target peripheral device, the group number of the target time group, and the target time slot number, the present invention realizes the synchronization and coordination of the network. Once the response packet of the target peripheral device is received, the central device will send a response confirmation packet and update the network table information, which is used to indicate the occupation of each time slot in each time group by the peripheral device. The location of the peripheral device is determined by the time group number and the time slot number, thereby achieving accurate positioning and management of the peripheral device. By synchronizing data packets and accurate time slot management, data conflicts and retransmissions are reduced, thereby improving the overall communication efficiency. By updating the network table information, the central device can better understand the occupancy of each time slot, thereby optimizing the resource allocation and utilization of the network. The present invention provides a flexible and efficient management method for a one-to-many network topology structure, so that the central device can better coordinate and control multiple peripheral devices, thereby optimizing the performance and stability of the entire network. The implementation details of this embodiment are described in detail below. The following content is only for the convenience of understanding the implementation details provided, and is not necessary for the implementation of this solution.

[0027] This embodiment is applied to the communication network node control process of the central device, such as Figure 1 As shown, including:

[0028] Step 101: The central device starts the transceiver and sends a synchronization data packet.

[0029] The central device sends a synchronization data packet with a specific operation code to the peripheral device, and the synchronization data packet contains the current time slot number of the target peripheral device, the time group number to be jumped, and the time slot number. By sending the synchronization data packet to the peripheral device, the central device realizes the designated control and scheduling of the peripheral device.

[0030] In one example, the central device sends a synchronization data packet with a specific operation code to the peripheral device to instruct the peripheral device to change the data transmission position.

[0031] In one example, the number of synchronization packets sent needs to be calculated. When the number of synchronization packets sent reaches a preset value m, the next step (S102) is entered. If the number of synchronization packets sent does not reach the preset value m, the process returns to S101 and continues to send synchronization packets until step 101' in the figure. The central device continuously sends more than m synchronization packets with the same information, where m is greater than 1, to ensure that the peripheral device can receive at least one synchronization packet.

[0032] Step 102: When the central device sends more than m synchronization data packets, the timer is set to the time interval between the current time and the time of the first synchronization data packet of the target time group to be jumped.

[0033] The timer is set to the time interval between the current time and the first synchronization data packet time of the target time group to be jumped to indicate that the central device receives the response packet of the peripheral device before the first synchronization data packet time of the target time group to be jumped. The central device continuously sends more than m synchronization data packets with the same information, m is greater than 1, to ensure that the peripheral device can receive at least one synchronization data packet.

[0034] Step 103: When the timer expires, the transceiver is started to continuously receive the response packet from the peripheral device.

[0035] Step 104: The central device sends a response confirmation packet and updates the network table information.

[0036] After the central device confirms the response of the peripheral device, it will send a response confirmation packet and update the network table information. Figure 2 As shown, updating the network table information includes setting the time slot number of the current peripheral device to an idle state, and setting the new time group number and time slot number of the peripheral device to an active state.

[0037] In one example, the time slot number of the current peripheral device is set to an idle state, and the new time group number and time slot number of the peripheral device are set to an active state, which is used to update the network position of the peripheral device and update multiple peripheral devices to the same time group, so that the central device only needs to send a synchronization data packet in the time group, and multiple peripheral devices can synchronously receive data from the central device.

[0038] This embodiment achieves network synchronization and coordination by broadcasting a synchronization data packet and carrying an operation code, the time slot number of the target peripheral device, the group number of the target time group and the target time slot number. Once a response packet of the target peripheral device is received, the central device will send a response confirmation packet and update the network table information, which is used to indicate the occupancy of the peripheral device in each time slot in each time group. The location of the peripheral device is determined by the time group number and the time slot number, thereby achieving accurate positioning and management of the peripheral device. Through synchronization data packets and accurate time slot management, data conflicts and retransmissions are reduced, thereby improving the overall communication efficiency. By updating the network table information, the central device can better understand the occupancy of each time slot, thereby optimizing the resource allocation and utilization of the network.

[0039] Another embodiment of the present invention relates to a communication network node control method, which is applied to peripheral devices, wherein a central device and a plurality of the peripheral devices form a one-to-many network topology structure, and the scheduling time is divided into a plurality of time groups, wherein a time group is used to correspond to at least two peripheral devices, including:

[0040] This embodiment is applied to the communication network node control process of the peripheral device, such as Figure 3 As shown, including:

[0041] Step 301: Start the transceiver, and the peripheral device receives the synchronization data packet broadcasted by the central device.

[0042] In one example, the synchronization data packet carries an operation code for indicating the type of network update, as well as the current time slot number of the target peripheral device, the target time group number to be jumped to, and the target time slot number; within the current time slot number, the location of the peripheral device is determined by the time group number and the time slot number.

[0043] Step 302: Start a timer and set the timer to the time interval between the current time and the time of the first synchronization data packet of the target time group to be jumped;

[0044] Step 303: When the timer expires, the transceiver is started, and the peripheral device sends a response packet to the central device.

[0045] In one example, the response packet carries an operation code for indicating a multi-point data transmission type and response information. The peripheral device sends a response packet to the central device for the central device to send a response confirmation packet and update network table information, and the network table information is used to indicate the occupation of each time slot in each time group by the peripheral device. The content of updating the network table information includes setting the time slot number of the current peripheral device to an idle state, and setting the new time group number and time slot number of the peripheral device to an active state.

[0046] Step 304: The peripheral device receives the response confirmation packet sent by the central device, sets the current peripheral device's time slot number to an idle state, and sets the new time group number and time slot number of the peripheral device to an active state, which is used to update the peripheral device's network position and update multiple peripheral devices to the same time group.

[0047] In this embodiment, a one-to-many topology network is implemented to allow the central device and a large number of peripheral devices to maintain stable and fast interactive communication. In a one-to-many network structure, time is divided into multiple time groups, and a time group contains multiple time slots. The central device and different peripheral devices perform two-way communication in different time slots. In a time group, the central device sends a synchronization data packet to carry data information, and indicates the receiving peripheral device in the synchronization data packet. In order to improve the efficiency of data transmission, before the central device sends data to multiple peripheral devices, the network position of these peripheral devices is updated, and these peripheral devices are updated to the same time group. The central device sends a synchronization data packet in the time group, so that multiple peripheral devices can synchronously receive the data of the central device. The network position of the peripheral device is determined by the time group number and the time slot number, and the network grouping control process of the central device on the peripheral device is successfully completed. The implementation of this process is expected to improve the communication efficiency of the network, reduce conflicts and optimize network performance, and provide a flexible and efficient management method for the one-to-many network topology.

[0048] The multi-device data transmission process of the communication network node control method in this embodiment is as follows: Figure 4 As shown, first, the central device sends a synchronization data packet of the network update type operation code, carrying the time group number N and the time slot number M1 to be jumped. This step serves as the trigger point of the entire process. By sending synchronization data packets to peripheral devices, the central device realizes the designated control and scheduling of peripheral devices.

[0049] After receiving the synchronization data packet, peripheral device #1 will send a response packet to confirm that it is ready to perform subsequent operations. After receiving the response from the peripheral device, the central device sends a response confirmation packet to confirm.

[0050] Next, peripheral device #1 sets the timer to the time interval between the current time and the time of the first synchronization packet of the time group to be jumped. When the timer time arrives, peripheral device #1 starts to receive synchronization packets, completes the execution of instructions and updates the network position.

[0051] In one example, the peripheral device #1 sets the timer to the time interval between the current time and the time of the first synchronization data packet of the time group to be jumped to indicate that the peripheral device receives the synchronization data packet before the jump time group.

[0052] Subsequently, the central device updates the network locations of multiple peripheral devices to the same time group according to the above steps. Through this process, the central device can perform efficient data transmission through the multi-point data transmission method. The central device sends a synchronization data packet of a multi-point data transmission type operation code, and the synchronization data packet contains the current time slot number of the target peripheral device, and transmits information with the target peripheral device in the time slot indicated by the target time slot number.

[0053] After receiving the synchronization data packet, multiple peripheral devices send response packets with operation codes of multi-point data transmission type in their respective specific time slots, and the response packets contain response information. After receiving the response packet, the central device sends a response confirmation packet to the peripheral device for confirmation, thereby completing the multi-point data transmission process.

[0054] The steps of the above method are divided only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the scope of protection of this patent.

The bus can also connect various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein.
