Problems solved by technology

Due to the invisibility of wireless electromagnetic waves, it is impossible for network deployment personnel to obtain real-time transmission performance of the deployed network in the current environment while deploying network nodes
In addition, while deploying the network, the construction personnel generally do not have a wealth of wireless communication knowledge. They only deploy the wireless multi-hop network based on simple construction experience. Often after the network deployment is completed, the network connectivity is not high, and the network The transmission performance is low, the information transmission path is unstable and frequently replaced, and the generation of isolated nodes prevents certain areas of information from being uploaded to the client, etc.

Embodiment 1

[0051] This embodiment provides an auxiliary device for wireless network deployment, figure 1 is a schematic diagram of the auxiliary device, such as figure 1 As shown, the auxiliary device 100 includes: a sending unit 101 , a collecting unit 102 , a first determining unit 103 , a second determining unit 104 , and a third determining unit 105 .

[0052] In this embodiment, the sending unit 101 is used for broadcasting a link detection request, and the collecting unit 102 is used for collecting link detection responses received within a predetermined time. The sending unit 101 and the collecting unit 102 can be realized by the wireless communication module as mentioned above.

[0053] In this embodiment, after the link detection response is collected by the sending unit 101 and the collection unit 102, the first determination unit 103 may use the node that sent the link detection response as the reference node of the device 100 to determine the For the target reference node a...

Embodiment 2

[0175] This embodiment also provides a portable terminal, Figure 14 is a schematic diagram of the portable terminal, such as Figure 14 As shown, the portable terminal 1400 includes the auxiliary device 100 described in Embodiment 1. Since the auxiliary device 100 has been described in detail in Embodiment 1, its content is incorporated here, and will not be repeated here.

[0176] Figure 15 It is a schematic block diagram of the system configuration of the portable terminal in this embodiment, as Figure 15 As shown, the portable terminal 1500 may include a central processing unit 1501 and a memory 1502; the memory 1502 is coupled to the central processing unit 1504. It is worth noting that this figure is exemplary; other types of structures may also be used in addition to or instead of this structure to implement telecommunications functions or other functions.

[0177] In one implementation, the functions of the auxiliary device 100 described in Embodiment 1 can be in...

Embodiment 3

[0189] The embodiment of the present invention also provides a wireless network deployment method. Since the problem-solving principle of this method is similar to that of the device in Embodiment 1, its specific implementation can refer to the implementation of the device in Embodiment 1, and the same content is not repeated. Repeat instructions.

[0190] Figure 16 is a flowchart of an embodiment of the method, such as Figure 16 As shown, the method includes:

[0191] Step 1601: broadcast link detection request;

[0192] Step 1602: Collect link detection responses received within a predetermined time;

[0193] Step 1603: Using the node sending the link detection response as a reference node, determine a target reference node and a non-target reference node of the device;

[0194] Step 1604: Determine the link connection status of the device relative to each reference node according to the received link detection response;

[0195] Step 1605: Determine the moving direct...
