These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a schematic flow chart of a wireless signal acquisition method provided in an embodiment of the present application, including a plurality of pieces of public facility equipment, on which wireless signal acquisition devices are respectively installed, the method being applied to the public facility equipment, and the method including steps S201 to S204.
First, the structure of the wireless signal acquisition device provided in the embodiment of the present application is explained in detail. Fig. 3 is a schematic structural diagram of a wireless signal acquisition device in an embodiment of the present application, and as shown in fig. 3, the wireless signal acquisition device may include a power supply module 31, a wireless signal acquisition module 32, a GPS (Global Positioning System) Positioning module 33, a CPU (central processing unit) processor 34, a data storage module 35, a signal sorting module 36, a wake-up control unit 37, and a signal transmission module 38. It is understood that the above modules are only exemplary embodiments of the wireless signal acquisition device of the present application, and are not limited to the wireless signal acquisition device, and the above modules may be increased or decreased according to the actual needs of the user.
Wherein, power module 31 can contain battery and power two parts for supply power to wireless signal collection system, for example when installing wireless signal collection system on solar street lamp, usable solar energy supplies power, and in some embodiments, wireless signal collection system can be supplied power by the power function power of communal facility equipment self-carrying, for example when installing wireless signal collection system on the camera, the power module that usable camera self is connected supplies power.
The wireless signal acquisition module 32 is responsible for acquiring wireless signals of a 3G (3rd Generation, third Generation mobile communication technology), a 4G (4th Generation, fourth Generation mobile communication technology), and a 5G (5th Generation, fifth Generation mobile communication technology) network.
The GPS positioning module 33 confirms the specific position of the public facility device by using the GPS positioning function, outputs the longitude and latitude of the signal acquired correspondingly, and encapsulates the longitude and latitude data and the wireless signal and transmits the encapsulated longitude and latitude data and the wireless signal to the intelligent public facility server for analysis. In some embodiments, the wireless signal acquisition device may be located by a location function that is self-contained by the utility equipment.
The CPU processor 34 completes the cooperation function of each module in the wireless signal acquisition device, including matching the longitude and latitude where the wireless signal acquired by the wireless signal acquisition module and the GPS positioning module determine the acquired signal, and completing the one-to-one correspondence function, it can be understood that, when the public facility equipment is not intelligent equipment, the wireless signal acquisition device needs to integrate a plurality of modules, and the CPU processor 34 is needed to cooperate among the modules.
And the data storage module 35 is used for storing the acquired data so as to analyze the signal quality condition in the following process. In some embodiments, because both the camera and the street lamp are powered by the power source or by solar energy, there is no power supply trouble compared to a shared bicycle. Therefore, data storage can be carried out at the camera and the street lamp device end, and data storage can not be carried out at the shared bicycle device end, namely, the data storage module is not installed at the shared bicycle device end, so that the power use speed is reduced, and the use time of the whole device is prolonged. Meanwhile, in some embodiments, the utility server may provide a dedicated data storage function, and the utility device may transmit the collected data to the utility server in real time for storage and analysis.
And the signal sorting module 36 is used for sorting the collected signals in the device and transmitting the screened signals to the public facility server. This module is suitable for situations where the intelligent utility server does not have a signal cleansing function, and in some embodiments the utility server provides a dedicated signal cleansing function, so that the signal conditioning module 36 may not be needed at this time.
And a signal transmission module 38, which is responsible for transmitting the acquired signals to the public facility server, and can be internally provided with a WIFI receiver or other network transmission equipment for performing a network transmission function. In some embodiments, the signal transmission function of the public facility equipment can be utilized to complete the signal transmission.
Next, a wireless signal acquisition method provided in the embodiment of the present application is described in detail with reference to fig. 3.
Step S201, collecting first wireless signal data in a preset area based on the wireless signal collecting device.
In this embodiment, the wireless signal acquisition module 22 in the wireless signal acquisition device is responsible for acquiring wireless signals of networks such as 3G, 4G, and 5G, where the wireless signal data includes network data such as signal quality, signal uplink level value, and signal downlink level value, and these network data can be used to test the quality and strength of the wireless signal.
Step S202, acquiring the position information of the acquired first wireless signal data.
In this embodiment, the GPS positioning module 23 in the wireless signal acquisition device can position the public facility device, and then output the position information, such as longitude and latitude and other information, of the first wireless signal data acquired correspondingly. In some embodiments, the location information of the first wireless signal data collected may also be obtained by using a GPS positioning module of the public facility device.
Step S203, encapsulating the position information and the first wireless signal data into second wireless signal data.
It can be understood that the process of encapsulating the first wireless signal Data and the position information may be implemented by using simple Data Encapsulation (Data Encapsulation), where the Data Encapsulation may map multiple service Data into a payload of a certain Encapsulation protocol, and then fill a packet header of a corresponding protocol to form a Data packet of the Encapsulation protocol.
Step S204, the second wireless signal data are sent to a public facility server, so that the public facility server analyzes the wireless network in the preset area according to the second wireless signal data.
Compared with the prior art, in which a tester holds a signal acquisition device by hand to a specific position to perform wireless signal acquisition and testing, in the embodiment, the wireless signal acquisition device is added in the public facility equipment, a plurality of public facility equipment are used for acquiring wireless signal data in different areas, and meanwhile, the position information of the acquired wireless signal data is encapsulated, that is, each wireless signal data corresponds to a specific position information, so that the public facility server analyzes the wireless signal data and the wireless network of the preset area according to the position.
It should be noted that, a person skilled in the art can adaptively set the range of the preset region in combination with the actual application.
Referring to fig. 4, fig. 4 is a schematic flow chart of another wireless signal acquisition method according to an embodiment of the present disclosure, based on the above embodiment, the present embodiment reduces power consumption of a wireless signal acquisition device by flexibly switching a sleep state and an operating state of the wireless signal acquisition device, and specifically, a default state of the wireless signal acquisition device is a sleep state, except for the above steps S201 to SS204, before acquiring first wireless signal data (step S201) in a preset area based on the wireless signal acquisition device, the present embodiment further includes step S401 and step S402.
Step S401, judging whether the public facility equipment enters the preset area, if so, executing step S402, otherwise, ending the process.
Step S402, awakening the wireless signal acquisition device from a sleep state to a working state.
In one embodiment, for example, a wireless signal acquisition device disposed on a non-fixed public facility device such as a sharing bicycle sets a preset area, wherein the preset area is also called an acquisition area, when the sharing bicycle runs to an area set in advance, a GPS positioning module built in the wireless signal acquisition device is matched with a GPS longitude and latitude of the set acquisition area, and after the longitude and latitude matching is successful, a wake-up control unit is triggered, a wireless signal acquisition instruction is issued through a CPU processor, and the wireless signal acquisition module starts to operate to acquire a wireless signal. Similarly, when the sharing bicycle drives away from the preset area, the built-in GPS positioning module of the wireless signal acquisition device is matched with the GPS longitude and latitude of the set acquisition area, and after the longitude and latitude matching is unsuccessful, the wireless signal acquisition device triggers the awakening control unit, issues a wireless signal acquisition stopping instruction through the CPU processor, and the wireless signal acquisition module stops working and does not acquire wireless signals any more.
Referring to fig. 5, fig. 5 is a schematic flow chart of another wireless signal acquisition method according to an embodiment of the present disclosure, based on the previous embodiment, in this embodiment, a wireless signal data acquisition cycle is set, wireless signal data is acquired within a certain time range, and frequent acquisition of wireless signals is avoided, so as to further reduce power consumption of a wireless signal acquisition device, specifically, in addition to the above steps S201 to S204, before step S201, the method further includes step S501, and step S201 is further divided into step S201 a.
Step S501, presetting an acquisition cycle for acquiring wireless signal data by the wireless signal acquisition device;
in step S201a, first wireless signal data in a preset area is acquired based on the wireless signal acquisition device in an acquisition period.
In one embodiment, taking the wireless signal acquisition device disposed on the public facility equipment at the position of the camera, the street lamp, etc. as an example, the acquisition period is set to be weekly, monthly, quarterly, etc. according to the user's demand and the actual network situation inside the device. After the collection period is set and the set time is reached, the awakening control unit 37 is triggered, a wireless signal collection instruction is issued through the CPU 34, the wireless signal collection module 32 starts to work to collect wireless signals, and the wireless signal collection device can be in a dormant state within the non-collection period time so as to effectively reduce the power consumption of the wireless collection device.
Based on the same technical concept, an embodiment of the present application provides another wireless signal acquisition method, as shown in fig. 6, including a plurality of pieces of public facility equipment, on which wireless signal acquisition devices are respectively installed, and the method is applied to a public facility server, and includes steps S601-S604.
Step S601, obtaining second wireless signal data sent by each piece of public facility equipment, where the second wireless signal data is obtained by acquiring, by each piece of public facility equipment based on a respective wireless signal acquisition device, first wireless signal data in a respective preset area and then encapsulating position information of the first wireless signal data and the first wireless signal data.
Specifically, a data receiving module is arranged in the public facility server, and the data receiving module is used for receiving first wireless signal data acquired by the wireless signal acquisition device and second wireless signal data packaged by position data. In the data transmission module 38 of the docking wireless signal acquisition device, since the sensor has a bus interface (such as RS-232), and the computer can directly read the signal acquired by the data transmission module through the corresponding bus, in some embodiments, after acquiring the second wireless signal data, the computer can store the acquired original wireless signal data (the first wireless signal data) in the back-end data storage module, thereby completing the metadata management.
Step S602, analyzing the wireless network in the preset area according to the second wireless signal data to obtain an analysis result.
In one embodiment, the second wireless signal data is first subjected to data processing, wherein the data processing may include extracting the first wireless signal data and the GPS location information from the second wireless signal data, then effectively integrating the first wireless signal data and the GPS location information, and further performing data cleaning, filtering, deleting invalid data, and the like. The data acquisition unit acquires data obtained by preprocessing the data in the data processing module. After data processing, wireless network analysis is performed on the first wireless signal data and the position information thereof, specifically, according to the wireless signal data and the position information after data processing, the conditions of signal intensity, signal quality and the like of each area are determined, and the conditions of each area are analyzed by combining a neural network algorithm and machine learning, so that more accurate signal conditions of each area wireless network can be obtained.
Further, a network optimization scheme can be obtained by combining with an operator network optimization task table. The data report unit automatically forms a report according to the preprocessed network quality condition and the network analysis condition, and stores and displays the report integrated with other network data tables to realize report visualization.
Step S603, obtaining area information corresponding to the wireless signal data to be operated and maintained based on the analysis result.
In one embodiment, the area information corresponding to the wireless signal data to be operated and maintained is obtained by acquiring the operation and maintenance management information and then integrating the operation and maintenance management information and the analysis result. It is understood that the operation and maintenance management information may include a signal strength threshold state, a signal quality threshold state, etc., and once a certain area is lower than the threshold state, the operation and maintenance of the wireless network of the area are required.
