It can be seen from the background technology that in the prior art, when troubleshooting a WLAN network through network management equipment and troubleshooting tools, now the network management equipment checks the faults in the detected area, and then engineers carry troubleshooting tools to go to the WLAN network. Perform on-site troubleshooting for failed terminals or equipment. It is also in the process of troubleshooting the WLAN network by adopting the method of the prior art.

Synchronization, so that it is impossible to determine the fault quickly or in the first time, and even cause the failure to be notified in time when the engineering personnel go to the site, which may easily lead to problems such as low troubleshooting efficiency.

Based on this, in the embodiment of the present invention, the mobile terminal on site accesses the wireless network through a certain AP on site, and the network management device locates the wireless network by using the received message reported by the AP in the wireless network The location information of the terminals and interference sources within the range, combined with the AP in the wireless network to generate the on-site 3D model; the mobile terminal obtains the on-site 3D model from the network management device, the area map of the area where it is located and the map of the area where it is located location information on . The mobile terminal determines its position on the 3D model of the site by sharing information with the network management equipment at the site, and then determines the detection area that can be covered by itself on the 3D model of the site, and then the AP that appears in the detection area, Quickly realize on-site fault detection for terminals and interference sources. The specific process is described in detail through the following embodiments of the present invention.

Embodiment one

As shown in Figure 1, it is a flowchart of a WLAN network fault detection method disclosed in Embodiment 1 of the present invention. The method is applied to a mobile terminal, and the method mainly includes the following steps:

Step S101, accessing a wireless network through an AP, where the wireless access point is any AP within the range of the wireless network;

In step S101, a mobile terminal accesses a current wireless network through an AP, and the mobile terminal is a mobile terminal held by an engineer. At the work site, the mobile terminal accesses the wireless network through a certain AP within the wireless network range of the site. There are multiple APs within the wireless network range of the work site, and their coverage areas may overlap or may be connected. The AP used by the mobile terminal is usually the closest AP to the mobile terminal.

Step S102, obtaining the location information of terminals and interference sources within the range of the wireless network calculated by the network management device based on the messages reported by the APs within the range of the wireless network, and according to the APs within the range of the wireless network, the terminals and The on-site 3D model generated by the location information of the interference source;

In step S102, the terminals within the range of the wireless network include the mobile terminal itself for fault detection and the target terminal to be detected.

Step S102 is executed, and the information obtained by the mobile terminal comes from the network management device. The network management device is mainly used to manage electronic devices such as APs and terminals within the range of the wireless network where the server it belongs to access the wireless network. In the process of executing step S101, the mobile terminal accesses the wireless network through a certain AP, and the AP uploads and synchronizes the terminal information of the accessed mobile terminal to the network management device, so that it can perform corresponding operations on the accessed mobile terminal. management.

Since most electronic devices access the wireless network through APs, the network management device performs positioning calculations based on the messages reported by multiple (at least one) APs within the range of the wireless network. The terminal accessing the wireless network and the interference source are positioned to obtain the location information of the terminal and the interference source within the range of the wireless network, and the terminal also includes the mobile terminal accessing the wireless network when performing step S101. Then use the location information of the positioned terminal and interference source, and the location information of each AP within the range of the wireless network to generate a corresponding on-site 3D model.

The location information of each AP within the range of the wireless network is known in advance by the network management device. Each AP located in the wireless network where the server to which the network management device belongs, including APs for accessing mobile terminals and APs for non-accessing mobile terminals, scans their surrounding terminals and interference sources according to preset scanning conditions or cycles The electronic device then reports the scanned message containing the information of the electronic device to the network management device, and the network management device performs related operations and management according to the reported message.

Among them, the operations carried out according to the message reported by the AP include: using the positioning algorithm to calculate the position of each electronic device, that is, the terminal (including the mobile terminal used to detect the fault) and the interference source in the wireless network; using the determined position of the terminal and the interference source, as well as information such as the location of each AP known in advance to generate a 3D model of the site.

Step S103, obtaining an area map of the area where the mobile terminal is located from the network management device according to the location information of the mobile terminal itself;

In step S103, the mobile terminal acquires an area map of the area where it is currently located from the network management device according to its own location information obtained by executing step S102. The area map is the background image of the area imported in advance by the network management device. That is to say, for the network management device, the background map of the area of the wireless network where the server it belongs to has been obtained in advance and stored in the network management device. It can form an information sharing relationship with the AP in the wireless network and the mobile terminal accessing the wireless network through the AP.

Step S104, according to the site 3D model, the area map and the location information of the mobile terminal itself, determine the position of the mobile terminal itself on the site 3D model, and calculate the position of the mobile terminal itself in the site The detection area that can be covered on the 3D model;

In step S104, after the mobile terminal calculates and superimposes the obtained on-site 3D model, the area map and its own location information, it can obtain its own location on the on-site 3D model, and then select the location that it can cover on the on-site 3D model. The area is the detection area.

It should be noted that the detection area displayed on the intercepted on-site 3D model of the mobile terminal can display the location information of the terminal located in the detection area, the interference source, and the AP. The location information of the terminal and the interference source is acquired through step S102.

Step S105, performing fault detection on the APs, terminals and interference sources determined to be located in the detection area.

In step S105, the mobile terminal performs fault detection on the APs, terminals and interference sources in the displayed detection area. If a certain AP, terminal or interference source is detected to be faulty, it can perform on-site troubleshooting according to the on-site detection results. Through the step S105, the fault can be found on site in real time, avoiding the problem in the prior art that the engineering personnel cannot know the fault at this time when they go to the site.

Embodiment 1 of the present invention is based on the wireless network of the server to which the network management device belongs and the AP in the wireless network. The mobile terminal accesses the wireless network through any AP in the wireless network, and the network management device accesses the wireless network through the AP in the wireless network. The reported message manages the terminals and interference sources within the range of the wireless network, and feeds back the information required by various mobile terminals to the mobile terminal, so that an information sharing relationship is formed between the network management device and the mobile terminal.

Based on this, the mobile terminal used to detect on-site faults calculates the location information of the terminals and interference sources within the range of the wireless network by obtaining the information in the message reported by the wireless access point in the wireless network by the network management device, and combines the The location of the wireless access point establishes the on-site 3D model, and the mobile terminal determines the detection area that can be covered by itself on the on-site 3D model through the on-site 3D model and the area map and position of the area where it is located, and then detects the wireless network located in the detection area. Access points, terminals, and interference sources are used for fault detection, so as to ensure that on-site faults can be found quickly, and then when faults are found in time, faults can be eliminated in a more timely manner to achieve the purpose of improving troubleshooting efficiency.

Embodiment two

Based on a WLAN network fault detection method disclosed in Embodiment 1 of the present invention, step S104 shown in FIG. Position on the 3D model of the scene, and calculate the detection area that can be covered by itself on the 3D model of the scene, its specific process is as shown in Figure 2, mainly includes the following steps:

Step S201, using the location information of the mobile terminal itself on the area map as the coordinate position of the mobile terminal itself in the on-site 3D model, using the compass and gyroscope of the mobile terminal to calculate The horizontal orientation and vertical orientation of the mobile terminal itself in the position;

In step S201, the location information of the mobile terminal itself can be obtained by step S102, and the map of the area where the mobile terminal is located can be obtained by executing step S103 through its own location information, and the location information of the mobile terminal itself can be used as the mobile terminal itself in the field 3D The coordinate location in the model. Since it is 3D, the mobile terminal can be at the coordinate position. Use your own compass and gyroscope to calculate your own horizontal and vertical orientation on the 3D model of the scene.

Step S202, superimposing the on-site 3D model and the area map to generate a superimposed image;

In step S202, it can be known from the description of step S103 in Embodiment 1 of the present invention that the area map refers to the background image of the area where the mobile terminal is located. After step S202 is executed, the area map used as the background image is superimposed with the on-site 3D model to generate an overlay image. In fact, the main body of the superimposed image is still the 3D model of the scene. As mentioned above, the area map is the background image of the scene. The purpose of this step S202 is to combine the on-site 3D model generated by executing step S102 with the on-site, so that the engineering personnel have a better sense of immersion when observing the display of the mobile terminal. Through this process, the on-site information acquired by the network management device is also shared with the mobile terminal.

Step S203, on the superimposed image, cut out a detection area from the superimposed on-site 3D model according to the horizontal orientation and vertical orientation, and the range covered by the camera equipment of the mobile terminal itself.

Execute step S203, the mobile terminal is on the superimposed image, actually on the 3D model of the scene with the added background, taking the horizontal direction and vertical direction obtained in step S202 as the direction reference, according to the range that the mobile terminal's own camera equipment can cover Select the corresponding area from the superimposed on-site 3D model, and use this area as the detection area.

That is to say, the direction when the mobile terminal intercepts is based on its own horizontal direction and vertical direction, and the area intercepted on the superimposed on-site 3D model is the area of the 3D model that can be seen by its own camera equipment, and This area is used as the area where the mobile terminal performs fault detection.

In addition, in step S104 shown in Figure 1, according to the site 3D model, the area map and the location information of the mobile terminal itself, determine its own position on the site 3D model, and calculate its position on the site The specific process of the detection area that can be covered on the on-site 3D model can also be shown in Figure 3, mainly including the following steps:

Step S301, using the location information of the mobile terminal itself on the area map as the coordinate position of the mobile terminal itself in the on-site 3D model, using the compass and gyroscope of the mobile terminal to calculate The horizontal orientation and vertical orientation of the mobile terminal itself in the position;

Step S302, superimposing the on-site 3D model and the regional map to generate a superimposed image;

Step S303, on the superimposed image, according to the horizontal orientation and vertical orientation, select a preset range from the superimposed on-site 3D model as a detection area.

The above-mentioned execution process and principle of step S301 and step S302 are the same as step S201 and step S202 disclosed in FIG. 2 , which can be referred to, and will not be repeated here. The content disclosed in FIG. 3 is different from that in FIG. 2 in that in step S303 , when the detection area is cut out from the superimposed on-site 3D model, the preset range is used as the basis for cutting out the detection range. The preset range can be set by engineering personnel. For example, the range that can be seen by the camera device on the mobile terminal is not the minimum range, but if you want to narrow the detection range, you can set it in advance. It should be noted that the preset range cannot exceed the range captured by the camera device on the mobile terminal.

In step S105 as shown in Figure 1, the wireless access point determined to be located in the detection area, the terminal and the interference source are detected for failure, as shown in Figure 4, mainly includes the following steps:

Step S401, calculating the horizontal distance and vertical distance between each AP, target terminal, interference source and the mobile terminal itself in the 3D model of the site;

In step S401, the calculated range is APs in the on-site 3D model (including APs accessed by the mobile terminal itself), target terminals (terminals located in the on-site 3D model except the mobile terminal used for fault detection), interference The distance between the source and the mobile terminal, the distance includes horizontal distance and vertical distance.

Step S402, selecting the AP whose horizontal distance and vertical distance are within the range of the detection area, the terminal and the interference source to perform fault detection, and the APs within the range of the detection area include the AP that the mobile terminal itself accesses;

In step S402, after executing step S401, the mobile terminal determines the positional relationship between itself and each AP in the on-site 3D model, the target terminal and the interference source, and then determines the calculated APs and target terminals according to the determined horizontal distance and vertical distance. Whether the terminal and the interference source are in the detection area determined by the mobile terminal, and then select the AP that meets the judgment conditions, the target terminal and the interference source for fault detection. The judgment is based on whether the appearance of each AP, target terminal and interference source in the detection area is complete or whether its position affects the fault detection. Among them, it can be completely displayed in the detection area and/or its location does not affect the fault detection. Judgment conditions.

During the fault detection process of step S402 performed by the mobile terminal, when it is detected that a fault occurs in a certain AP, target terminal and/or interference source located in the detection area, the engineering personnel can target the currently faulty AP, target terminal and/or Or interference sources to carry out targeted troubleshooting, avoiding the problem that the fault cannot be found in time.

Embodiment 2 of the present invention is also based on the information sharing between the network management device and the mobile terminal, and the mobile terminal determines the detection area for fault detection, so as to perform fault detection and troubleshooting in the detection area. Through the information sharing established between the network management device and the mobile terminal, faults can be found in real time, thereby guiding engineering personnel to troubleshoot, and achieving the purpose of improving troubleshooting efficiency.

Embodiment Three

Based on the WLAN network fault detection method disclosed in Embodiment 1 and Embodiment 2 of the present invention, step S105 as shown in FIG. 1 is executed, the terminal determines the wireless access point located in the detection area Carry out fault detection with the source of interference, as shown in Figure 5, in combination with the execution steps in the accompanying drawing 1, specifically include the following steps:

Step S1051, marking the position of the horizontal section at a preset height in the detection area;

When step S1051 is executed, the mobile terminal marks the horizontal section of the field strength to be acquired in the subsequent execution of step S1052 according to a preset height.

Step S1052, obtaining a field strength coverage simulation plan corresponding to the horizontal section from the network management device;

When step S1052 is executed, the mobile terminal obtains from the network management device the field intensity coverage simulation plan corresponding to the horizontal section marked in step S1051. The field strength in the field strength coverage simulation plan is actually the content contained in the message reported by the AP in the process of executing step S102, and the field strength of the AP, terminal and interference source in the wireless network obtained by the network management device Construct a field strength map. After step S104 is executed to determine the detection area, the position of the horizontal section within the detection area is marked according to the preset height by executing step S1051, and then step S1052 is executed to obtain the field corresponding to the horizontal section of the detection area from the network management device Strong coverage simulation floor plan.

Step S1053, superimposing the field strength coverage simulation plan and the horizontal section;

In step S1053, the horizontal section and the field strength coverage simulation plan acquired in the above steps S1051 and S1052 are superimposed. The superimposed schematic diagram is shown in Figure 6, which shows the scene captured by the PAD (a type of mobile terminal) camera, which is an office, where the hatched part is the field strength coverage simulation plan and the horizontal section The superimposed part is marked with A in Figure 6.

Step S1054, performing fault detection on at least one of the AP, the terminal and the interference source in the weak signal area displayed on the field strength coverage simulation plan.

Execute step S1054, the mobile terminal performs detection according to the displayed strong and weak areas on the field strength coverage simulation plan, because the places with weak field strength signals are often prone to faults, so focus on detecting APs in the displayed weak signal areas , terminals and/or interferers.
