Background

In recent years, wireless communication technologies have been rapidly developed, such as Wi-Fi, bluetooth, Long Range (Long Range), 125kHz Radio Frequency Identification (RFID) technology, and the like. Wi-Fi is a technology that allows electronic devices to connect to wireless local area networks, typically using the 2.4GHz or 5GHz radio frequency bands. Bluetooth is a wireless technology, can realize short-distance data exchange among fixed equipment, mobile equipment and a building personal area network, uses a 2.4GHz-2.485GHz ultrahigh frequency band, and is the same as the Bluetooth technology in Wi-Fi technology and belongs to short-distance wireless technology used in offices and families.

The LoRa is one of Low Power Wide Area internet of things (LPWAN for short) communication technology centers, and is an ultra-long distance wireless transmission scheme based on a spread spectrum technology, and the LoRa is commonly used in 470.3MHz-509.7MHz frequency bands in China at present. The 125kHz RFID works in an inductive coupling mode, is widely applied to the fields of animal identification, industrial and civil water meters and the like, is a long-distance wireless transmission scheme, and has the working frequency range of 100kHz-150kHz and the central frequency of 125 kHz.

The radio frequency Signal test mainly refers to testing the coverage condition of a radio frequency Signal, a Received Signal Strength value (RSSI), a Signal to Noise ratio (SNR), Noise interference of an environment and the like, wherein the coverage condition refers to detecting whether the environment interferes with the radio frequency Signal and the coverage condition when a radio Signal base station is installed at a certain position, the RSSI mainly detects the quality of a radio frequency link, and the environmental interference Noise refers to the influence of other devices with the same frequency or high power and different frequency on the radio Signal base station, and the Noise interference causes the problem of uplink reception of the base station so as to influence the radio Signal coverage.

At present, various terminals such as mobile phones, notebooks and the like have the functions of Wi-Fi and Bluetooth, so that various Wi-Fi and Bluetooth signal detection methods and detection software exist at present. However, currently, there is no general-purpose terminal with LoRa function or other non-general-purpose radio frequency signals such as 125kHz RFID, and currently, the methods for detecting such radio signals mainly include: before installing the wireless base station, a professional carries out frequency sweeping of signal interference by matching with a handheld frequency spectrograph, and after the wireless base station is installed, a wireless radio frequency terminal product is used for sending a data packet to the wireless base station and checking the signal condition on a service platform; or directly installing a wireless base station, arranging a data transceiver at the wireless base station, sending a data packet to the wireless base station by using a wireless radio frequency terminal product, and manually recording each test position and the RSSI and the SNR corresponding to the position.

However, in the first detection method, one hand-held spectrometer needs thousands of cells, which is high in detection cost, and a base station needs to transmit a data packet to a wireless radio frequency terminal, and then, the signal condition is checked on a service platform, which results in heavy operation.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic flow chart of a method for testing a radio frequency signal according to an embodiment of the present invention, as shown in fig. 1, the method includes:

step S11, receiving test configuration information of the wireless radio frequency signal;

specifically, when a certain wireless radio frequency signal needs to be tested, a tester firstly inputs or selects test configuration information of the wireless radio frequency signal on a mobile terminal, and after the mobile terminal receives the test configuration information, the mobile terminal connects a surveying device, for example, the mobile terminal turns on a bluetooth device, and connects the surveying device through bluetooth, wherein the surveying device refers to a device having a wireless radio frequency signal transceiving function. And then, the switch and the Bluetooth module of the first survey equipment are turned on, the Bluetooth of the first survey equipment automatically broadcasts, the mobile terminal turns on the Bluetooth, and the first survey equipment is connected after the Bluetooth broadcast of the first survey equipment is scanned. Taking 125kHz radio frequency signals as an example, when the coverage condition of the radio frequency signals needs to be tested, the test configuration information of the 125kHz radio frequency signals is firstly set, after the setting is completed, the mobile terminal acquires the test configuration information of the 125kHz radio frequency signals, and then the mobile terminal is connected with 125kHz radio frequency surveying equipment in a bluetooth mode.

Step S12, sending a test instruction to a first survey device according to the test configuration information, so that the first survey device tests the radio frequency signal according to the test instruction and obtains a test result;

specifically, after the mobile terminal determines the test configuration information of the wireless radio frequency signal, a test instruction of the wireless radio frequency signal is generated according to the test configuration information, the test instruction is sent to the first surveying equipment through the Bluetooth, after the first surveying equipment receives the test instruction, the wireless radio frequency signal is tested according to the test instruction, a test result is obtained, and then the test result is sent to the mobile terminal through the Bluetooth.

And S13, receiving the test result sent by the first survey equipment, and displaying the test result according to a preset display mode.

Specifically, the mobile terminal receives a test result sent by the first surveying device through bluetooth, and displays the test result according to a preset display mode, for example, the mobile terminal displays the received wireless radio frequency signal strength in a graphic mode, or the mobile terminal directly displays a wireless radio frequency signal strength value, and the like. Therefore, when a certain test point needs to be tested, the first surveying equipment is placed at the test point, the Bluetooth is turned on, the mobile terminal is connected, the test configuration information is input or selected at the mobile terminal, the mobile terminal sends a test instruction to the first surveying equipment, the wireless radio frequency signal test result corresponding to the test point can be checked from the mobile terminal, the operation is simple, convenient and quick, and the operation result is visual.

On the basis of the foregoing embodiment, further, the test configuration information includes: starting channel information and a first sweep interval;

Specifically, before the radio frequency signal base station is installed, the environmental noise needs to be tested, that is, at which frequencies there is interference, so that, firstly, the frequency domain frequency sweep test needs to be performed on the background noise of the radio frequency signal, that is, the frequency domain frequency sweep is performed on other background noise signals except the radio frequency signal in the spatial environment. Specifically, it is necessary to set the starting channel information and the first frequency sweeping interval at the mobile terminal, for example, 96 channels are uplink and 48 channels are downlink for the LoRa signal. Generally, 8 continuous uplink channels and 8 continuous downlink channels are used, and the frequency domain frequency sweeping is performed to test which channels are available and which channels have larger interference and are unavailable. After the initial channel and the first sweep interval are set, the mobile terminal generates a frequency domain sweep command according to the sweep configuration information, the frequency domain sweep command is sent to the first surveying equipment, the first surveying equipment sweeps all available channels from the initial channel, and obtains the received signal strength of each sweep, for example: the initial channel is 0, the first surveying equipment automatically configures a stop channel to be 9, scans 10 channels (including 8 continuous channels) each time, then automatically sets the initial channel to be 10 and the like, wherein the frequency scanning process is that the first surveying equipment continuously switches the frequency of a phase-locked loop (PLL) of a radio frequency chip in the surveying equipment according to a set first scanning interval, for example, 50kHz, so that the received signal strength of various signals in an environment space is received according to the first scanning interval, which is recorded as first received signal strength RSSI, and is abbreviated as RSSI-1, and the bottom noise received by the system of the first surveying equipment can be obtained according to the RSSI-1, and generally the range of the system bottom noise is between-105 dBm and-110 dBm. And then, the RSSI-1 is sent to the mobile terminal through the Bluetooth, and the mobile terminal displays the RSSI-1 according to a preset display mode. Fig. 2 is a schematic diagram of a frequency domain frequency sweeping result according to an embodiment of the present invention, as shown in fig. 2, the upper limit of the frequency sweeping is 473.3Mhz, the lower limit of the frequency sweeping is 475.1Mhz, the first frequency sweeping interval (also referred to as a step value) is 50kHz, the frequency fluctuation at the channel 8 is large, an interference signal affects reception, and when the frequency is switched to a frequency near the channel 8, the RSSI-1 value read out is larger than the system noise floor. Through testing, it can be known that the radio frequency signal cannot be transmitted and received through the channel 8 when in use, otherwise, interference can be caused.

According to the method for testing the wireless radio frequency signal, the mobile terminal and the surveying equipment are connected through the Bluetooth serial port, the mobile terminal receives the testing configuration information of the wireless radio frequency signal and sends a frequency domain frequency sweeping command to the surveying equipment, and the surveying equipment obtains the system noise according to the frequency domain frequency sweeping command.

On the basis of the foregoing embodiments, further, the test configuration information includes: frequency sweep frequency, frequency sweep times and a second frequency sweep interval;

Specifically, after the interference frequency is tested through frequency domain frequency sweeping, time domain frequency sweeping may be performed, where time domain frequency sweeping refers to testing the duration and the interference intensity of a certain interference frequency. When performing time domain frequency sweeping on a wireless radio frequency signal, frequency sweeping frequency, frequency sweeping times and a second frequency sweeping interval need to be set, then, every second frequency sweeping interval of the first surveying device receives a space signal with the same frequency as the frequency sweeping frequency, namely, receives the background noise of the wireless radio frequency signal with the same frequency sweeping frequency, obtains the received signal strength, which is denoted as second received signal strength RSSI, abbreviated as RSSI-2, and sends the RSSI-2 to a mobile terminal, fig. 3 is a schematic diagram of a time domain frequency sweeping result provided by an embodiment of the present invention, as shown in fig. 3, the frequency sweeping frequency is 470.3MHz, the frequency sweeping times is 30, and the second frequency sweeping interval is 100 ms. RSSI-2 was acquired every 100ms on the first survey equipment at a received spatial signal frequency of 470.3MHz, and as can be seen from fig. 3, there was discontinuous interference at 470.3MHz, each interference having a duration of about 300ms and an interference strength of-50 dBm. By means of frequency sweeping of the time domain and the frequency domain and combining with a strong display function of the mobile terminal, a tester can detect interference from the time domain and the frequency domain, accurately obtain information such as interference frequency, interference intensity, interference duration and the like, provide data support for subsequent installation of a base station or a wireless radio frequency signal terminal product, and enable subsequent planning and installation equipment to be more reasonable.

According to the method for testing the wireless radio frequency signal, the mobile terminal and the surveying equipment are connected through the Bluetooth serial port, the mobile terminal receives the testing configuration information of the wireless radio frequency signal and sends a time domain frequency sweeping command to the surveying equipment, and the surveying equipment obtains a time domain frequency sweeping result.

On the basis of the foregoing embodiments, further, the test configuration information includes: the PING packet configuration information and the test mode of the wireless radio frequency signal;

acquiring location information of the first survey equipment;

Specifically, when testing the radio frequency signal, besides testing the environmental interference signal strength, it is also necessary to test the information of the received signal strength, the signal to noise ratio, etc. of the radio frequency signal, therefore, in practical application, the PING packet configuration information and the testing mode of the radio frequency signal may be set at the mobile terminal, the testing mode is a testing mode selected according to the need, for example, before the radio frequency signal base station is erected, if the testing base station is erected at a certain position, the coverage condition of the radio frequency signal in the peripheral area, this testing mode may be recorded as a test before installation, or the radio frequency signal base station is already erected, the received strength of the radio frequency signal at a certain testing point is tested, and this testing mode may be recorded as a test after installation. In addition, the test mode may be a mode of dividing the test mode by regions.

After receiving the PING packet configuration information and the test mode, the mobile terminal sends a PING packet command to the first surveying equipment, the first surveying equipment selects a corresponding test end according to the test mode, for example, the test mode is a pre-installation test, the test end corresponding to the first surveying equipment is other surveying equipment and is marked as second surveying equipment, and if the test mode is a post-installation test, the test end corresponding to the first surveying equipment is a radio frequency signal base station due to the existence of the base station. And then performing PING packet test between the first survey equipment and the test end. Specifically, the first surveying equipment sends a radio frequency signal PING packet to the testing end, the testing end obtains the received signal strength and the signal to noise ratio SNR after receiving the uplink PING packet, the received signal strength and the signal to noise ratio SNR are recorded as a third received signal strength RSSI, abbreviated as RSSI-3, and sends a downlink PING packet, the RSSI-3 and the SNR to the first surveying equipment, and the first surveying equipment sends the testing results of the uplink PING packet and the downlink PING packet, including the RSSI-3 and the SNR, to the mobile terminal.

After the mobile terminal obtains the test result, the position information of the first surveying equipment is obtained, the position is used as a test point, the Bluetooth is in short-distance transmission, the mobile terminal can obtain the position information of the mobile terminal through a built-in Global Positioning System (GPS) module and is used as the position information of the first surveying equipment, then the position information and the test result corresponding to the position information are correlated according to the test mode, the position and the test result are displayed on the mobile terminal according to a preset display mode, and a tester can visually check the test result of each test point.

In practical application, the coverage condition of the radio frequency signal at a certain fixed position can be directly tested, the position of the test point can be preset, the position of the test point is added in the test configuration information, for example, the position of the test point is selected or input, then a tester places the first surveying equipment at the position of the test point, and then the mobile terminal and the first surveying equipment are connected through bluetooth, so that the signal coverage condition of each test point can be tested. Specifically, the mobile terminal generates a test instruction according to the test configuration information, the test instruction is sent to the first surveying equipment, after the first surveying equipment receives the test instruction, the wireless radio frequency signal PING packet is sent to the corresponding test end according to the sweep frequency configuration information, the test result of the PING packet is obtained, and the test result is sent to the mobile terminal.

The method for testing the wireless radio frequency signal provided by the embodiment of the invention has the advantages that the mobile terminal and the surveying equipment are connected through the Bluetooth serial port, the mobile terminal receives the test configuration information of the wireless radio frequency signal and sends a test instruction to the surveying equipment, the surveying equipment sends the wireless radio frequency signal PING packet to the test end at the position of the test point and calculates the test result of the PING packet.

On the basis of the above embodiments, further, the test method includes: indoor testing or outdoor testing;

Specifically, in order to facilitate the mobile terminal to display the test result of the wireless radio frequency signal, the test mode in the received test configuration information may include an indoor test or an outdoor test, the indoor test is to perform a signal test on a closed space such as a building, and since the base station is generally erected outdoors, when the indoor test is selected, the purpose is to test the coverage strength of each test point of the base station in a certain building, therefore, the test end of the PING packet with the surveying device may be the wireless radio frequency signal base station, and when the outdoor test is selected, the test end of the PING packet with the surveying device may be the wireless radio frequency signal base station or the second surveying device, where the second surveying device is mainly used to simulate the wireless radio frequency signal base station to receive and transmit the wireless radio frequency signal.

For example, the test mode that the mobile terminal receives the radio frequency signal is indoor test, the test point is indoor test point 1, a first survey device is placed on the test point 1, then the first survey device and the mobile terminal are connected through Bluetooth, a PING packet command is sent to the first survey device, the first survey device sends a radio frequency signal PING packet to a radio frequency signal base station, the base station obtains uplink RSSI-3 after receiving the uplink PING packet, sends downlink PING packet and RSSI-3 to the first survey device, the first survey device obtains downlink RSSI-3, a radio frequency signal test result is determined according to the uplink PING packet and the uplink RSSI-3, the test result is sent to the mobile terminal, and the mobile terminal displays the test point 1 and the corresponding test result.

For example, the test mode of the mobile terminal receiving the radio frequency signal is outdoor test, the test point is an outdoor test point 2, the first survey equipment is placed at the test point 2, the second survey equipment is placed at the location where the radio frequency signal base station is to be erected, acting as a radio frequency signal base station, then connecting the first surveying equipment and the mobile terminal through Bluetooth, sending a test instruction to the first surveying equipment, sending a radio frequency signal PING packet to the second surveying equipment by the first surveying equipment, acquiring uplink RSSI-3 after the second surveying equipment receives the uplink PING packet, sending a downlink PING packet to the first surveying equipment, acquiring downlink RSSI-3 by the first surveying equipment, and determining a wireless radio frequency signal test result according to the uplink and downlink PING packets and the uplink and downlink RSSI-3, sending the test result to the mobile terminal, and displaying the test point 2 and the corresponding test result by the mobile terminal. Through the mobile terminal, the tester can look over directly perceivedly and erect the base station in a certain position after, the test result of each test point to can predict base station erection position, because it is big to directly build base station work load, the base station is arranged and still need consider power, various network configuration etc. and the base station is heavy again and is difficult to carry, consequently uses two survey equipment point-to-point PING package tests, makes the operation simpler and more convenient, and can practice thrift a large amount of manpower, material resources.

Specifically, in order to view the test result of each test point more intuitively, the mobile terminal may further obtain a test map corresponding to the test mode, for example, when the test mode is an indoor test, the mobile terminal obtains the corresponding test map by importing a building picture or modeling an indoor building; when the test mode is outdoor test, the mobile terminal can directly acquire an outdoor GPS map and take the map as a test map.

Fig. 4 is a schematic diagram of a test map provided by an embodiment of the present invention, as shown in fig. 4, in practical application, a mobile terminal may first obtain the test map, and then a tester selects a test point through the test map, for example, 105 is used as the test point in fig. 4, and through building modeling, the tester may directly click or drag in the test map to implement a function of inputting the test point. And after the mobile terminal receives the test result, directly marking the test point on the test map and displaying the test result of the test point.
