Embodiment 1

[0017] In the embodiment of the present invention, the star network communication method according to the present invention may include: when the central device sends the work order, the work order is sent to the sub-device through the sending module of the channel as the center sending channel; the sub-device receives the work order through the terminal module Work instructions; when the sub-device sends work information, set the channel of the terminal module as the central receiving channel; the sub-device sends the working information to the central device through the terminal module with the channel as the central receiving channel; the central device uses the channel as the central receiving channel The receiving module receives work information.

[0018] The purpose of the embodiments of the present invention is to solve the problem of low communication efficiency caused by frequent switching of the sending state or receiving state of the star network central equipment. ...

Embodiment 2

[0036] figure 2 A schematic structural diagram of a star network center device according to the present invention is shown.

[0037] Such as figure 2 As shown, in the embodiment of the present invention, a star network center device is proposed. The center device 1 includes: a sending module 101 with a channel as the center sending channel, which is used to send a work order to the device when the center module sends a work order The channel is the receiving module 102 of the central receiving channel, which is used to receive the work information sent by the sub-device when the sub-device sends the work information.

[0038] Different from the traditional star network, an additional wireless module is installed on the central device 1, in which the sending module 101 is dedicated to sending, and sends work instructions to the sub-device through the central sending channel; the receiving module 102 is dedicated to receiving, and receiving through the central receiving chann...

Embodiment 3

[0043] image 3 A schematic structural diagram of the star network sub-equipment according to the present invention is shown.

[0044] Such as image 3 As shown, in the embodiment of the present invention, a star network sub-device is proposed, and the sub-device 2 includes: a terminal module 201, which is used to receive a work order when the central device sends a work order; a first channel setting module 202, It is used to set the channel of the terminal module 201 as the central receiving channel when the sub-device 2 sends working information; the terminal module 201 is also used to send the working information to the central device through the terminal module 201 whose channel is the central receiving channel.

[0045] image 3 The solid line in the center represents the central sending channel, and the dotted line represents the central receiving channel, from image 3 It can be seen from the figure that the default state of the sub-device 2 is the waiting state, wa...

Abstract

The invention discloses a star network communication method, central equipment, sub-equipment and a communication system. The method includes the following steps: when the central equipment sends a working instruction, sending the working instruction to the sub-equipment through a sending module of which the channel is a central sending channel; enabling the sub-equipment to receive the working instruction through a terminal module; when the sub-equipment sends working information, setting the channel of the terminal module as a central receiving channel; enabling the sub-equipment to send theworking information to the central equipment through the terminal module of which the channel is the central receiving channel; and enabling the central equipment to receive the working information through a receiving module of which the channel is the central receiving channel. By adopting the star network communication method, the central equipment, the sub-equipment and the communication system, provided by the invention, the problem of packet loss caused by frequently switching the sending state or the receiving state of the central equipment can be solved, the number of nodes that can besimultaneously processed by the system for communication can also be increased, and the processing speed is also increased to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and in particular relates to a star network communication method, central equipment, sub-equipment and communication system. Background technique [0002] The structure of the star network is a center and a topology of multiple sub-nodes. It has simple structure, convenient connection, relatively easy management and maintenance, strong scalability, and small network delay time. In a star network, it is very easy to add and reduce devices without affecting the work of other devices in the system. Therefore, this topology is often used in popular smart home platforms. However, when designing and building smart home platforms It is found that wireless communication is limited, and there are fewer nodes that can process communication at the same time. When there are many nodes, the processing speed is slow, and even frequent packet loss directly. The reason is that in the existing star ne...
