DETAILED DESCRIPTION

[0050] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0051] See also Figures 1 to 7 The present invention provides a 5.8 GHz radio frequency wireless communication device for an underground pipe gallery, specifically comprising:

[0052] The network detection module 1 is used to collect communication channel data, and perform data monitoring and analysis to obtain low-intensity channels;

[0053] Specifically include:

[0054] The data acquisition submodule 101 is used to collect communication signal data of each channel using a communication sensor, where the communication signal data includes network delay and network fluctuation;

[0055] By collecting network delay and network fluctuation data, we can lay the foundation for subsequent data analysis.

[0056] The data analysis submodule 102 is used to analyze the communication signal data.

[0057] Specifically include:

[0058] The network delay analysis unit 1021 is used to compare the collected network status data with a preset standard or threshold to determine whether the network delay is within an acceptable range and whether the packet loss rate remains at a low level;

[0059] By having the staff preset the standard value of the network status in advance, the system can then determine whether the collected network data is qualified; this helps in the subsequent analysis of network trends, thereby improving the quality of network trend analysis.

[0060] The network fluctuation analysis unit 1022 is used to process the data using statistical methods to calculate the average value, standard deviation, maximum value and minimum value indicators to understand the fluctuation of the network status and the overall performance;

[0061] In the network status data, the average value can be used to represent the average level of indicators such as network delay and throughput, the standard deviation can be used to measure the degree of fluctuation of indicators such as network delay and packet loss rate, and the maximum and minimum values ​​are used to represent the maximum and minimum possible values ​​of indicators such as network delay and throughput, so as to understand the extreme performance of the network; thus, combining these data, we can understand the fluctuation of the network.

[0062] The network trend analysis unit 1023 is used to identify the change trend of all the above network states through a time series analysis method, determine whether the signal strength therein is gradually increasing or decreasing, whether the network load presents periodic changes, select the ones with weakened signal strength, and obtain the low-intensity channel.

[0063] Apply the time series decomposition method (additive model or multiplicative model) to decompose the network status data into trend, seasonal and periodic components. By observing the trend component, identify the long-term upward or downward trend of the network status indicators; use the fast Fourier transform (FFT) spectrum analysis method to identify the periodic components in the network status data; determine whether there is a periodic change in the network load based on the frequency and amplitude of the periodic components; based on the results of trend identification, select the channels whose signal strength shows a weakening trend, and then further identify the low-intensity channels by setting thresholds or comparing with other channels.

[0064] The regional signal identification module 2 is used to identify the specific location of the weak signal area based on the low-intensity channel;

[0065] Specifically include:

[0066] The camera graphics acquisition submodule 201 is used to capture graphics of the underground pipe gallery through a camera;

[0067] By taking a large number of images of the underground pipeline corridor, a three-dimensional model can be constructed later.

[0068] The underground pipe gallery model building submodule 202 is used to generate a three-dimensional model based on the captured images;

[0069] By setting up cameras in the underground tunnel to collect images of the underground tunnel, and then integrating and processing the images through 3D modeling technology to construct a 3D model, the weak signal areas can be marked on the 3D model later, so that the staff can check the weak signal areas at any time.

[0070] The communication signal threshold setting submodule 203 is used to set the threshold of the communication signal in each area of ​​the underground pipe gallery;

[0071] Set a threshold for the signal strength so that it can be marked later when the channel strength is lower than the threshold.

[0072] The map annotation submodule 204 is used to generate a annotation point in the three-dimensional model after the low-intensity channel is lower than a threshold;

[0073] After marking the marked points on the three-dimensional model, they can also be displayed in a highlighted flashing manner so that the staff can pay attention and observe the low-intensity channels in the underground pipe gallery at any time, thereby facilitating timely processing and ensuring stable network coverage.

[0074] The blind area identification submodule 205 is used to connect multiple marked points to form the weak signal area, indicating that the communication signal in this area is weak.

[0075] When a large number of marked points appear, these marked points can be connected and finally an area is produced, which is the weak signal area. The staff can check and maintain the underground pipeline corridor according to the weak signal area to improve the work efficiency of the staff.

[0076] The dynamic channel allocation module 3 is used to select the best channel from all channels and apply it to the weak signal area;

[0077] Specifically include:

[0078] The optimal channel selection submodule 301 is used to select the best channel among all current channels;

[0079] Specifically include:

[0080] The channel statistics unit 3011 is used to record all channel data, including the frequency, bandwidth, and modulation mode of the channel;

[0081] The channel data is recorded to facilitate subsequent search for the optimal channel.

[0082] The channel database unit 3012 is used to establish a channel storage database based on all channels to store and manage channel information;

[0083] All channels are recorded and stored to avoid channel data loss and facilitate subsequent channel sorting.

[0084] The channel sorting unit 3013 is used to sort the channels in the channel storage database, and arrange the channels with good data from top to bottom;

[0085] The high-intensity signals and the low-intensity signals are sorted from top to bottom and displayed in the upper control center so that the staff can observe the best channel and the worst channel at any time. The staff can then replace the worst channel with the best channel in time, and then go to check the worst channel (the low-intensity channel) based on its position on the three-dimensional model.

[0086] The channel selection unit 3014 is used to select a channel with the best data sorting and apply it in the weak signal area.

[0087] The best channel will replace the worst channel in time to ensure the stability of network coverage in the underground tunnel.

[0088] The channel multiplexing submodule 302 is used to ensure that adjacent areas use channels of different frequencies.

[0089] Specifically include:

[0090] The channel detection unit 3021 is used to detect all channels;

[0091] The frequencies of all channels are detected, and the information is then displayed in the upper control center for staff to observe. After the channel frequencies are detected, the channel adjustment unit 3022 can be performed later.

[0092] The channel adjustment unit 3022 is used to make adjustments when detecting that adjacent channels are the same, to ensure that adjacent areas use channels of different frequencies to reduce spectrum overlap and interference;

[0093] In a 5.8GHz radio frequency wireless communication network, if adjacent wireless access points (APs) use the same channel, their signals may overlap, resulting in signal interference. This interference will reduce network performance and affect the speed and stability of data transmission. By detecting that adjacent channels are the same and making adjustments to ensure that adjacent areas use channels of different frequencies, this signal interference can be effectively reduced and the overall performance of the network can be improved.

[0094] The interference control unit 3023 is used to reduce the interference level and improve the communication quality by adopting power control technology.

[0095] In the 5.8 GHz radio frequency, according to the change of the input power on the 5.8 GHz radio frequency path, the corresponding attenuation value is automatically adjusted to keep its output power constant, thereby avoiding the influence of power fluctuation, reducing the interference level, and improving the communication quality.

[0096] The resource optimization module 4 is used to allocate the resources and bandwidth of the channel and enhance the low-intensity channel.

[0097] Specifically, it includes:

[0098] The dynamic resource allocation sub-module 401 is used to allocate the communication resources and bandwidth of other high-intensity channels in the underground pipe gallery to the low-intensity channel;

[0099] When allocating the resources and bandwidth of high-intensity channels, the unused high-intensity channels are preferentially allocated. After all the unused channels are allocated, the allocation starts from the high-intensity channel with the lowest utilization rate, avoiding affecting the channels that are in use and have a high utilization rate. When all the high-intensity channels with a utilization rate below 60% are allocated, the dynamic allocation of high-intensity channels stops; at this time, the subsequent load balancing operation is performed.

[0100] The load balancing sub-module 402 is used to adopt load balancing technology to disperse the traffic in high-load areas to low-load areas to improve the overall network performance;

[0101] Load balancing technology distributes requests to multiple servers, enabling the system to handle more concurrent requests, thereby improving the overall processing capacity and performance. This helps ensure that the system can still maintain a stable response speed during high-traffic periods; when one of the servers fails or becomes unavailable, the load balancer can automatically forward requests to other available servers. This failover mechanism helps reduce the risk of single-point failures, improve the reliability and fault tolerance of the system, and thus rely on load balancing technology to improve the stability and performance of the network.

[0102] The resource reservation sub-module 403 is used to reserve 5% of the communication resources and bandwidth when allocating resources to all channels. When there are no extra communication resources and bandwidth available for high-intensity communication, the reserved resources are used to allocate to the low-intensity channel.

[0103] By reserving resource bandwidth, when all the high-intensity channels with a utilization rate below 60% are allocated, the reserved 5% communication resources and bandwidth can be used for emergency, further ensuring the coverage stability of the 5.8 GHz radio frequency wireless communication network.

[0104] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
