[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, each embodiment of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be understood by those skilled in the art that in each embodiment of the present invention, many technical details are provided 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 solutions claimed in this application can be implemented. The division of the following embodiments is for convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined with each other and referenced to each other under the premise that there is no contradiction.

[0027] One embodiment of the present invention relates to a communication network node control method that can be applied to a central device. In this embodiment, a central device and multiple peripheral devices form a one-to-many network topology. The method includes: broadcasting a synchronization data packet containing an operation code indicating the type of network update, as well as the current time slot number of the target peripheral device, the group number of the target time group to be jumped to, and the target time slot number; upon receiving a response packet from the target peripheral device, sending a response confirmation packet and updating network table information indicating the occupancy of each time slot within each time group by peripheral devices; wherein the position of the peripheral device is determined by the time group number and time slot number. By broadcasting a synchronization data packet containing the 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 achieves network synchronization and coordination. Upon receiving a response packet from the target peripheral device, the central device sends a response confirmation packet and updates network table information indicating the occupancy of each time slot within each time group by peripheral devices. The location of the peripheral device is determined by the time group number and time slot number, thereby achieving precise positioning and management of the peripheral device. By synchronizing data packets and accurately managing time slots, data conflicts and retransmissions are reduced, thereby improving overall communication efficiency. By updating 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 one-to-many network topology structures, enabling the central device to 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 and is not necessary for the implementation of this solution.

[0028] The communication network node control process applied to the central device of this embodiment is shown in FIG1 and includes:

[0029] Step 101: The central device starts the transceiver and sends a synchronization data packet.

[0030] The central device sends a synchronization data packet with a specific operation code to the peripheral device. The synchronization data packet contains the current time slot number of the target peripheral device, the group number of the time group to jump to, 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.

[0031] 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.

[0032] In one example, the number of synchronization packets sent is counted. When the number of synchronization packets sent reaches a preset value m, the process proceeds to the next step (S102). If the number of synchronization packets sent does not reach the preset value m, the process returns to S101 and continues sending synchronization packets until step 101' in the figure. The central device continuously sends more than m synchronization packets containing the same information, where m is greater than 1, to ensure that the peripheral device receives at least one synchronization packet.

[0033] 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.

[0034] 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, which is used to instruct the central device to receive the response packet of the peripheral device before the time of the first synchronization data packet of the target time group to be jumped. The central device continuously sends more than m synchronization data packets with the same information, where m is greater than 1, to ensure that the peripheral device can receive at least one synchronization data packet.

[0035] Step 103: When the timer expires, the transceiver is started to continuously receive response packets from the peripheral device.

[0036] Step 104: The central device sends a response confirmation packet and updates the network table information.

[0037] After the central device confirms the peripheral device's response, it sends a response confirmation packet and updates the network table information. As shown in Figure 2, the content of the updated network table information includes setting the current peripheral device's time slot number to idle and setting the peripheral device's new time group number and time slot number to active.

[0038] 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.

[0039] This embodiment achieves network synchronization and coordination by broadcasting a synchronization data packet 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. Upon receiving a response packet from the target peripheral device, the central device sends a response confirmation packet and updates the network table information, which indicates the occupancy status of the peripheral device in each time slot within each time group. The location of the peripheral device is determined by the time group number and time slot number, thereby achieving precise positioning and management of the peripheral device. Synchronization data packets and precise time slot management reduce data conflicts and retransmissions, thereby improving overall communication efficiency. By updating the network table information, the central device can better understand the occupancy status of each time slot, thereby optimizing the allocation and utilization of network resources.

[0040] Another embodiment of the present invention relates to a communication network node control method, which is applied to peripheral devices. A central device and multiple peripheral devices form a one-to-many network topology. The scheduling time is divided into multiple time groups, where each time group is used to correspond to at least two peripheral devices, including:

[0041] The communication network node control process applied to the peripheral device of this embodiment is shown in FIG3 , including:

[0042] Step 301: Start the transceiver, and the peripheral device receives the synchronization data packet broadcast by the central device.

[0043] In one example, the synchronization packet carries an operation code indicating a network update type, a current time slot number of the target peripheral device, a target time group number to jump to, and a 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.

[0044] 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;

[0045] Step 303: When the timer expires, the transceiver is started and the peripheral device sends a response packet to the central device.

[0046] In one example, the response packet carries an opcode indicating the multipoint data transmission type and response information. The peripheral device sends the response packet to the central device, which then sends a response confirmation packet and updates network table information indicating the occupancy of each time slot within each time group by the peripheral device. Updating the network table information includes setting the current peripheral device's time slot number to an idle state and simultaneously setting the peripheral device's new time group number and time slot number to an active state.

[0047] Step 304: The peripheral device receives the response confirmation packet sent by the central device, sets the time slot number of the current peripheral device to the idle state, and sets the new time group number and time slot number of the peripheral device to the active state, which is used to update the network position of the peripheral device and update multiple peripheral devices to the same time group.

[0048] In this embodiment, a one-to-many network topology enables stable and fast interactive communication between a central device and a large number of peripheral devices. In this one-to-many network, time is divided into multiple time groups, each containing multiple time slots. The central device and different peripheral devices conduct bidirectional communication within different time slots. Within a time group, the central device sends synchronization packets carrying data information and also indicates the receiving peripheral devices in the synchronization packets. To improve data transmission efficiency, before the central device sends data to multiple peripheral devices, it updates the network locations of these peripheral devices and places them in the same time group. The central device then sends synchronization packets within this time group, allowing multiple peripheral devices to synchronously receive data from the central device. The peripheral device's network location is determined by its time group number and time slot number, allowing the central device to smoothly control the network grouping of peripheral devices. This process is expected to improve network communication efficiency, reduce conflicts, and optimize network performance, providing a flexible and efficient management method for one-to-many network topologies.

[0049] Figure 4 illustrates the multi-device data transmission process using the communication network node control method in this embodiment. First, the central device sends a synchronization packet containing a network update opcode, along with the time group number N and time slot number M1 to which the device is to be redirected. This step serves as the trigger for the entire process. By sending synchronization packets to peripheral devices, the central device implements designated control and scheduling of these devices.

[0050] 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.

[0051] Next, peripheral device #1 sets a timer to the interval between the current time and the time of the first sync packet of the time group to be jumped. When the timer expires, peripheral device #1 begins receiving sync packets, completing the execution of the instruction and updating the network location.

[0052] 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 packet of the time group to be jumped to instruct the peripheral device to receive the synchronization packet before the jump time group.

[0053] The central device then follows the above steps to update the network locations of multiple peripheral devices to the same time group. This process enables efficient data transmission using multipoint data transmission. The central device sends a synchronization packet with a multipoint data transmission type opcode. This synchronization packet contains the current time slot number of the target peripheral device. Information is then transmitted to the target peripheral device in the time slot indicated by the target time slot number.

[0054] After receiving the synchronization data packet, the peripheral devices each transmit a response packet containing the multipoint data transmission type in their respective time slots. The response packet contains the response information. After receiving the response packet, the central device sends a response confirmation packet to the peripheral device to confirm the transmission, thus completing the multipoint data transmission process.

[0055] The steps of the above method are divided only for the purpose of clear description. During implementation, 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 or introducing insignificant designs to the algorithm or process without changing the core design of the algorithm and process are all within the scope of protection of this patent.

[0057] Processor 502 and processor 501 are connected using a bus. The bus may include any number of interconnected buses and bridges, connecting various circuits of one or more processors 501 and processor 502. The bus may also connect various other circuits such as peripheral devices, voltage regulators, and power management circuits. These are all well known in the art and, therefore, will not be described further herein. The bus interface provides an interface between the bus and the transceiver. The transceiver may be a single component or multiple components, such as multiple receivers and transmitters, providing a unit for communicating with various other devices over a transmission medium. Data processed by processor 501 is transmitted over a wireless medium via an antenna. Furthermore, the antenna receives data and transmits it to processor 501.

[0058] Processor 501 is responsible for managing the bus and general processing, and can also provide various functions, including timing, peripheral interfaces, voltage regulation, power management and other control functions. Processor 502 can be used to store data used by processor 501 when performing operations.
