These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0039] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0040] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0041] First, the terms involved in this application are explained:

[0042] LoRa (Long Range Radio) is a low-power, long-distance wireless communication technology.

[0043] LoRaWAN (Long Range Wide Area Network) is a low-power wide area network standard built based on LoRa technology, which defines a complete network architecture; LoRaWAN systems often include nodes, gateways, network servers and other auxiliary equipment; between nodes and gateways, data is transmitted in the form of LoRa signals.

[0044] Node, also known as LoRa node, is a device that collects and sends data through the LoRa wireless module. It is the data source of LoRaWAN and is used to collect and read data.

[0045] The gateway is a radio device equipped with a LoRa module. When used, it is responsible for receiving data packets from nodes and converting these data into a format suitable for transmission on the Internet, and then sending the data to the cloud server. During field testing, the gateway is used to receive data packets from field test equipment.

[0046] The site test equipment is used to test the LoRa signal quality at various locations in the site, so as to facilitate the subsequent deployment of nodes at locations with stronger LoRa signal quality. It can also be used to determine the comprehensive signal quality of gateways deployed at different locations by comprehensively evaluating the signal quality to determine the optimal gateway deployment location. Signal quality can be any one or more of the following parameters: packet loss rate, signal strength, signal-to-noise ratio, transmission rate, etc.

[0047] When deploying a LoRaWAN network, field testing is required to determine the locations of gateways and nodes so that the deployed gateways can cover more site areas and that the signal quality of the nodes at the locations selected in each area of ​​interest within the covered area is better; in related technologies, the gateway usually uploads test data to a server (the server can be a cloud server or a built-in server in the gateway). After the server calculates the test results, it sends the test results to the user end through other communication means other than LoRa technology (for example, it is sent to an app on the user's mobile phone specifically for viewing signal quality data). The test results are viewed through the user end, which results in low test efficiency and is extremely dependent on the signal quality of other communication means.

[0048] The signal testing method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the field test device 102 communicates with the gateway 104 via the LoRaWAN network.

[0049] The field test device 102 can respond to the test instruction and send an uplink test message to the gateway at the current test location; the gateway 104 can obtain the uplink signal quality data based on the uplink test message from the server (the server can be a cloud server or a built-in server in the gateway), and return it to the field device 102. The field test device 102 can obtain the signal quality data of the field test device at the current test location based on the information received from the gateway 104; the signal quality data includes uplink signal quality data, and the uplink signal quality data can be any one or more of the following parameters of the uplink: packet loss rate, signal strength, signal-to-noise ratio, transmission rate, etc.; the field test device 102 can also respond to the first result display instruction and display the first signal test result based on the signal quality data of the current test location.

[0050] The signal testing method provided in the embodiment of the present application implements signal testing only through the interaction between the field test equipment and the gateway, and the test results are viewed on the field test equipment. There is no need to interact with the server and the user end using communication technologies other than the LoRa technology, which reduces the dependence on other communication technologies and reduces the communication overhead of the signal test, and can realize instant viewing of the test results; and, to view the test results through the user end, it is necessary to transmit data through the mobile network, and in the scenario of the node to be deployed, the mobile network may be poor; the field test equipment and the gateway of the present application interact through the LoRa signal. Compared with the mobile network, the LoRa signal has a wide coverage range and strong anti-interference ability. The LoRa signal is used for interaction throughout the entire process of the signal test, which effectively improves the data transmission efficiency.

[0051] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0052] In some embodiments, Figure 2 As shown, a signal testing method is provided, which is applied to Figure 1 Taking the field test equipment in the example as an example, the above method includes:

[0053] S202, in response to the test instruction, sending an uplink test message to the gateway at the current test location, so that the gateway determines uplink signal quality data based on the uplink test message, and sends a downlink message carrying the uplink signal quality data to the field test equipment.

[0054] The test instruction is used to instruct the start of the test; in actual applications, the tester operates the field test equipment and triggers the test instruction through the UI (human-computer interaction) interface of the field test equipment.

[0055] It is understandable that the field test equipment includes a display component, such as a display screen, which can be a touch screen or a non-touch screen; the display component can be used to display a UI interface, and the tester can trigger the test command through the UI interface.

[0056] The current test position is the current location of the field test equipment. During the test, the field test equipment can change its test position in the area to be deployed, perform tests at each test position, and obtain test results at each test position. Subsequently, based on the test results of each test position, a test position with good signal quality can be selected in the area to be deployed to deploy nodes in the area to be deployed.

[0057] The uplink test message is a test message sent by the field test equipment to the gateway. The signal quality of the uplink (the field test equipment sends data to the gateway) can be determined through the uplink test message. The uplink signal quality data is used to indicate the signal quality of the uplink. In practical applications, the uplink signal quality data may include at least one of: uplink packet loss rate, uplink signal strength, or uplink signal-to-noise ratio.

[0058] Specifically, when the field test equipment is in the current test position, the tester triggers a test command on the field test equipment, the field test equipment responds to the test command, encapsulates the data to be sent into an uplink test message, and sends an uplink test message to the gateway. The gateway receives the uplink test message, determines the uplink signal quality data based on the uplink test message, encapsulates the uplink signal quality data into a downlink message sent to the field test equipment, and sends the downlink message to the field test equipment.

[0059] After receiving the uplink test message, the gateway can send the uplink test message to the server, which can be a cloud server or a built-in server of the gateway. The server determines the uplink packet loss rate and / or the signal strength and uplink signal-to-noise ratio based on the number of data packets included in the uplink test message sent by the gateway to obtain uplink signal quality data. The gateway is configured with a data acquisition plug-in, which enables the gateway to obtain data from the server, and then the gateway can obtain uplink signal quality data from the server.

[0060] It should be noted that the number of uplink test messages can be one or more. When the field test equipment is in the current test position, multiple uplink test messages can be sent to the gateway in sequence. Each of the multiple uplink test messages will carry sequence number information, so that the gateway or server can calculate the uplink packet loss rate based on the sequence number information of the received uplink test message. The uplink signal quality data can be the packet loss rate or other common signal quality parameters in the LoRa field.

[0061] In one implementation, a preset number of messages can be set. For ease of description, the preset number of messages is recorded as N. When the number of uplink test messages received by the gateway is less than or equal to N, the current uplink packet loss rate is calculated based on the uplink test messages less than or equal to N; when the number of uplink test messages received by the gateway exceeds N, the real-time uplink packet loss rate can be calculated based on the latest N test messages received; for example, when the Nth uplink test message is received, the current uplink packet loss rate is calculated based on the 1st to Nth uplink test messages, and when the N+1th uplink test message is received, the current uplink packet loss rate is calculated based on the 2nd to N+1th uplink test messages. The preset number of messages can be set according to actual needs, for example, N can be 50, and this is not limited in the embodiments of the present application.

[0062] In another implementation, the gateway can calculate the current uplink packet loss rate in real time based on all uplink test messages currently received. For example, when the mth uplink test message is received, the current uplink packet loss rate is calculated based on the 1st to mth uplink test messages. When the m+1th uplink test message is received, the current uplink packet loss rate is calculated based on the 1st to m+1st uplink test messages.

[0063] In another implementation, the field test device may send multiple uplink test messages to the gateway in sequence until the number of uplink test messages sent reaches a message number threshold and stops sending. After the field test device stops sending uplink test messages, the gateway calculates the uplink packet loss rate based on the received uplink test messages.

[0064] S204, based on the downlink message sent by the gateway, obtaining uplink signal quality data of the field test equipment at the current test location.

[0065] Specifically, the gateway encapsulates the uplink signal quality data into a downlink message, and after receiving the downlink message, the field test equipment extracts the uplink signal quality data from the downlink message.

[0066] That is to say, the gateway can calculate the uplink signal quality data based on the built-in server, or obtain the uplink signal quality data calculated by the cloud server, encapsulate the uplink signal quality data into the downlink message, and send the downlink message to the field test equipment to send the uplink signal quality data to the field test equipment. Since the gateway and the field test equipment communicate through LoRa signals, the field test equipment does not need to rely on other communication means to obtain the uplink signal quality data (for example, through WIFI, 4G, 5G and other technologies to communicate with the server to obtain the uplink signal quality data calculated by the server). Compared with other communication means, LoRa signals have a wide coverage range and strong anti-interference ability. LoRa signals are used for interaction throughout the entire process of signal testing, which effectively improves data transmission efficiency and reduces the requirements for environmental communication signals.

[0067] In some embodiments, the downlink signal quality data of the downlink can also be calculated; for example, the field test device sends a quality for testing the downlink signal quality to the gateway, and through the interaction between the gateway and the server, the gateway sends a downlink test message to the field test device, so that the field test device calculates the downlink signal quality data based on the received downlink test message. Calculating both the uplink signal quality data and the downlink signal quality data can more comprehensively reflect the signal transmission quality between the field test device and the gateway.

[0068] S206: In response to the first result display instruction, display the first signal test result based on the uplink signal quality data of the current test position.

[0069] The first result display instruction is used to instruct to display the first signal test result; in actual applications, the tester can initiate the first result display instruction through the UI interface of the field test equipment.

[0070] The number of signal quality data can be one or more; when the number of signal quality data is one, the first signal test result is used to visualize the signal quality data; when the number of signal quality data is multiple, the first signal test result is used to reflect the change of the signal quality quantity during the test period.

[0071] In actual applications, the uplink test message sent by the field test equipment to the gateway at the current test position may include multiple rounds of uplink test messages. Accordingly, the field test equipment can receive multiple rounds of downlink messages, and thus obtain multiple rounds of uplink signal quality data; the time period from the start time to the end time corresponding to the multiple rounds is the test time period of the current test position; that is, when the field test equipment is at the current test position, it can send multiple uplink test messages to the gateway in sequence within the test time period, and thus obtain multiple uplink signal quality data.

[0072] In one possible implementation, the amount of uplink signal quality data is one, and the first signal test result is detailed information of the uplink signal quality data; the field test equipment responds to the first result display instruction to display the detailed information of the uplink signal quality data based on the uplink signal quality data of the current test location.

[0073] In another possible implementation, the number of uplink signal quality data is multiple, and the first signal test result is a signal quality line graph representing the changes of multiple uplink signal quality data over time; the field test equipment responds to the first result display instruction to display the uplink signal quality line graph based on the multiple uplink signal quality data of the current test location.

[0074] In the signal testing method provided in the embodiment of the present application, the field test equipment sends an uplink test message to the gateway, and the gateway determines the uplink signal quality data according to the uplink test message. The field test equipment receives the downlink message sent by the gateway, and obtains the uplink signal quality data of the field test equipment at the current test position according to the downlink message. The field test equipment responds to the first result display instruction and displays the first signal test result based on the uplink signal quality data of the current test position.

[0075] In the related art, nodes and gateways are required to send test data to the server, which calculates the test results and sends them to the user end, and the test personnel view the test results through the user end; in the present application, signal testing is achieved only through the interaction between the field test equipment and the gateway, and the test results are viewed on the field test equipment, without the need to interact with the server and the user end, thereby reducing the communication overhead of the signal test and enabling instant viewing of the test results; and viewing the test results through the user end requires data to be transmitted through the mobile network, which is poor in the scenario of the nodes to be deployed; the field test equipment of the present application obtains the uplink signal quality data directly from the gateway through the LoRa technology, rather than using other communication means such as 4G and other communication technologies to obtain the uplink signal quality data from the server. Compared with methods using other communication means, the LoRa signal has a wide coverage range and strong anti-interference ability, and the LoRa signal is used for interaction throughout the entire process of the signal test, which effectively improves the data transmission efficiency and reduces the requirements for the communication signal of the environment.

[0076] In some embodiments, after obtaining the uplink signal quality data of the field test equipment at the current test location, it also includes: obtaining a label of the current test location; saving the signal quality data of the current test location and the label in association; the signal quality data includes one or more of the following: uplink signal quality data, downlink signal quality data; the type of signal quality data includes one or more of the following: packet loss rate, signal strength, signal-to-noise ratio and transmission rate; based on the signal quality data of the current test location, displaying a first signal test result, including: obtaining a label associated with the signal quality data of the current test location; based on the signal quality data and the label of the current test location, displaying the first signal test result.

[0077] The signal quality data may include uplink signal quality data and / or downlink signal quality data; and the first signal test result may include a signal test result corresponding to the uplink signal quality data and / or downlink signal quality data. Exemplarily, the signal quality data may include uplink signal quality data and downlink signal quality data, and the first signal test result includes an uplink signal quality line graph and a downlink signal quality line graph.

[0078] In a possible manner, before responding to the test instruction, the tag of the current test location may be obtained, and after determining the signal quality data of the field test equipment at the current test location, the signal quality data of the current test location and the tag may be associated and saved.

[0079] Among them, the label represents the location information of the current test location; in actual applications, the label can be set by the tester through the field test equipment. For example, before starting the test at the current test location, the tester inputs the test period and location information through the UI interface of the field test equipment. This location information is the label of the current test location. The label can also be automatically obtained by the field test equipment. For example, the field test equipment is equipped with a GPS (Global Positioning System) module, and the GPRS module can obtain the current location information of the field test equipment. The location information obtained by the GPRS positioning module can be used as the label of the current test location.

[0080] Specifically, the field test equipment obtains the label of the current test location. After obtaining the signal quality data of the current test location, the field test equipment associates and saves the signal quality data of the current test location with the label. In the case where there are multiple signal quality data, the signal quality data can be associated and saved with the label after each signal quality data is obtained.

[0081] Accordingly, the field testing equipment responds to the first result display instruction, obtains the label associated with the signal quality data of the current test location, generates and displays the first signal test result based on the signal quality data and the label of the current test location; that is, the displayed first signal test result includes the location information of the current test location; it can be understood that the signal quality data obtained from the signal test is associated with the test period of the signal test, and the generated first test result can also include the associated test period.

[0082] In one possible manner, the field testing equipment can perform multiple signal tests on the current test location. For each signal test, the signal quality data obtained from the signal test is associated with the signal test period. When the current test location includes signal quality data under multiple test periods, multiple test periods can be displayed. After selecting any test period, the first result display instruction is triggered, and then the field testing equipment responds to the first result display instruction, obtains the test period carried by the first result display instruction (any selected test period), obtains the signal quality data of the current test location under the test period, and generates and displays the first signal test result based on the signal quality data of the current test location under the test period.

[0083] Specifically, the first signal test result can be a signal quality line graph; there are multiple signal quality data, and the multiple signal quality data have their own test moments (each moment within the test period associated with the signal quality data). The first coordinate axis is determined in order from front to back of the test moments, and the second coordinate axis is determined according to the signal quality data, and then a signal quality line graph of the signal quality data that changes with the test moments within the test period is generated and displayed.

[0084] In the case where the signal quality data includes uplink signal quality data, the uplink signal quality data includes at least one of an uplink packet loss rate, an uplink signal strength, or an uplink signal-to-noise ratio, and the signal quality line graph may include at least one of a line graph whose second coordinate axis is a line graph of uplink packet loss rate, a line graph whose second coordinate axis is a line graph of uplink signal strength, or a line graph whose second coordinate axis is an uplink signal-to-noise ratio.

[0085] When the signal quality data also includes downlink signal quality data, the downlink signal quality data includes at least one of a downlink packet loss rate, a downlink signal strength, or a downlink signal-to-noise ratio, and the signal quality line graph may also include at least one of a line graph whose second coordinate axis is a downlink packet loss rate, a line graph whose second coordinate axis is a downlink signal strength, or a line graph whose second coordinate axis is a downlink signal-to-noise ratio.

[0086] In the above embodiment, the field test equipment responds to the first result display instruction and displays the first signal test result according to the signal quality data and label of the current test location, so that the tester can directly view the first signal test result through the field test equipment at the test site, so that the tester can perform subsequent tests based on the first signal test result, and there is no need to view the first signal test result through the user terminal, thereby improving the test efficiency; and the signal quality data includes uplink signal quality data and / or downlink signal quality data, which can more comprehensively reflect the signal transmission quality between the field test equipment and the gateway.

[0087] In some embodiments, the signal testing method further includes: in response to a second result display instruction, obtaining signal quality data of the field testing equipment at one or more test locations; obtaining labels respectively associated with the signal quality data of the one or more test locations; and displaying a second signal test result based on the signal quality data and labels of multiple test locations.

[0088] The second result display instruction is used to instruct to display the second signal test result. In actual applications, the tester can initiate the second result display instruction through the UI interface of the field test equipment.

[0089] Similarly, before conducting a test at a certain test location, or after obtaining the signal quality data of a certain test location, the label of the test location can be obtained, and the label of the test location and the signal quality data can be associated and saved. In this way, the associated labels can be obtained respectively according to the signal quality data of multiple test locations, and the signal quality data of multiple test locations can be obtained respectively according to multiple labels.

[0090] The second signal test result can reflect the signal quality data of one or more test locations. The difference in signal quality data of one or more test locations can be intuitively understood through the second signal test result, which is convenient for determining the location of the deployed node in multiple test locations.

[0091] Specifically, a second result display instruction is triggered on the UI interface of the field testing equipment. The field testing equipment responds to the second result display instruction and displays a signal quality data selection page. The tester selects signal quality data of multiple test locations on the page. The field testing equipment obtains labels associated with the signal quality data of the multiple test locations, and displays the second signal test result based on the signal quality data and labels of the multiple test locations.

[0092] In one possible manner, labels of multiple test locations are displayed on the UI interface of the field testing equipment. After the tester selects a label through the UI interface of the field testing equipment, a second result display instruction is triggered. The field testing equipment responds to the second result display instruction, obtains one or more labels carried by the second result display instruction, obtains signal quality data of one or more associated test locations based on the multiple labels, and displays the second signal test result based on the signal quality data and labels of the one or more test locations.

[0093] In the above embodiment, the second signal test result can be displayed based on the signal quality data and labels of one or more test locations. The difference in signal quality data of one or more test locations can be intuitively understood through the second signal test result, which facilitates determining the location of the deployed node in multiple test locations.

[0094] In some embodiments, multiple test locations belong to the area to be deployed; the label includes location information; the second signal test result includes a signal quality heat map; based on the signal quality data and labels of the multiple test locations, the second signal test result is displayed, including: obtaining a map of the area to be deployed; based on the map, the location information and signal quality data of the multiple test locations, the signal quality heat map is displayed.

[0095] Among them, the area to be deployed can be a building, park, industrial scene and other areas; multiple test locations belong to the area to be deployed, and the test site tests the signal quality data of the equipment at multiple test locations to facilitate determining the location of the deployment node in multiple test locations.

[0096] Specifically, the label includes location information, which can be obtained through the GPS module of the field test equipment; the field test equipment obtains a map of the area to be deployed, determines the multiple location points on the map corresponding to the location information of multiple test locations, and draws a signal quality heat map based on the multiple location points on the map and the signal quality data of the multiple test locations; in the signal quality heat map, the better the signal quality of the location point, the darker the color, and the worse the signal quality of the location point, the lighter the color. The signal quality heat map can be used to intuitively understand the difference in signal quality of multiple test locations in the area to be deployed.

[0097] It should be noted that for each test location, there may be multiple signal quality data. The multiple signal quality data of the test location can be averaged to obtain the average signal quality data of the test location; then, a signal quality heat map can be displayed based on the map, the average signal quality data of multiple test locations and the location information.

[0098] In one possible manner, when a map of the area to be deployed is not obtained, the field test equipment can display a signal quality scatter plot based on the location information and signal quality data of multiple test locations; the signal quality scatter plot is used to reflect the difference in signal quality of signal quality data of different location information; unlike the signal quality heat map, the signal quality scatter plot does not display a map of the area to be deployed.

[0099] In the above embodiment, a signal quality heat map can be displayed based on the location information (labels), signal quality data and maps of multiple test locations. The signal quality heat map can be used to intuitively understand the difference in signal quality of multiple test locations in the area to be deployed, thereby improving the efficiency of signal testing and the diversity of signal test result display.

[0100] In some embodiments, the signal testing method further includes: sending an instruction for testing the downlink signal quality to the gateway so that the gateway captures the instruction for testing the downlink signal quality from the server to send a downlink test message to the field test equipment; and calculating the downlink signal quality data based on the received downlink test message.

[0101] Specifically, the field test device sends an instruction for testing the downlink signal quality to the gateway, the gateway sends the instruction for testing the downlink signal quality to the server, the gateway captures the instruction for testing the downlink signal quality from the server, and sends a downlink test message to the field test device, and the field test device calculates the downlink signal quality data based on the downlink test message.

[0102] The downlink signal quality data may include at least one of downlink signal strength, downlink signal-to-noise ratio, or downlink packet loss rate.

[0103] In one possible manner, after the field test equipment obtains the downlink signal quality data, it can encapsulate the downlink signal quality data into the uplink test message sent to the gateway in the next round, that is, the uplink test message of the current round encapsulates the downlink signal quality data of the previous round; in this way, the gateway can obtain the downlink signal quality data of the current round based on the uplink test message of the next round. Since the uplink signal quality data of the current round is determined by the gateway, the gateway can obtain the uplink signal quality data and the downlink signal quality data of the current round. The gateway stores the uplink signal quality data and the downlink signal quality data so that the uplink signal quality data and the downlink signal quality data of each test location can be viewed through the gateway later.

[0104] In actual applications, there is a situation where the gateway sends data to the field test equipment. Therefore, when testing the signal, adding the test of the downlink signal quality data can improve the comprehensiveness and accuracy of the signal test. In the above embodiment, the uplink signal quality data and the downlink signal quality data can fully reflect the signal quality of the link between the gateway and the field test equipment, thereby improving the accuracy of the signal test.

[0105] For example, Figure 3 As shown, the tester triggers a test instruction through the field test equipment, and the field test equipment responds to the test instruction and sends an uplink test message to the gateway at the current test position. The gateway determines the uplink signal quality data according to the uplink test message, and encapsulates the uplink signal quality data into the downlink message. The gateway sends a downlink message to the field test equipment, and the field test equipment extracts the uplink signal quality data from the downlink message; the tester triggers an instruction for testing the downlink signal quality through the field test equipment, and the field test equipment sends the instruction to the gateway. The gateway sends the instruction for testing the downlink signal quality to the server, and the gateway grabs the instruction for testing the downlink signal quality from the server, sends the downlink test message to the field test equipment, and the field test equipment calculates the downlink signal quality data according to the downlink test message; the field test equipment triggers a first result display instruction, and the field test equipment responds to the first result display instruction to display the first signal test result based on the uplink signal quality data and the downlink signal quality data of the current test position.

[0106] In some embodiments, the signal testing method further includes: in response to a report generation instruction, obtaining signal quality data of multiple test locations, and generating a report based on the signal quality data of the multiple test locations; in response to a report export instruction, exporting the generated report in an export method corresponding to the report export instruction.

[0107] Among them, the export method can be to store the report to an external storage medium, wherein the external storage medium includes but is not limited to a USB flash drive, an external hard drive and an SD card; the export method can also be to generate a graphic code corresponding to the report, and the report can be viewed by scanning the graphic code later, and the graphic code can be a QR code; the export method can also be to generate a download link for the report, and the report can be obtained through the download link; the export method can also be other methods.

[0108] In the signal testing method provided in the embodiment of the present application, the field test equipment sends an uplink test message to the gateway, and the gateway determines the uplink signal quality data according to the uplink test message. The field test equipment receives the downlink message sent by the gateway, and obtains the signal quality data of the field test equipment at the current test position according to the downlink message. The field test equipment responds to the first result display instruction and displays the first signal test result based on the signal quality data of the current test position.

[0109] In the related art, nodes and gateways are required to send test data to the server, which calculates the test results and sends them to the user end, and the test personnel view the test results through the user end; in the present application, signal testing is achieved only through the interaction between the field test equipment and the gateway, and the test results are viewed on the field test equipment. There is no need to interact with the server and the user end, which reduces the communication overhead of the signal test and enables instant viewing of the test results; and viewing the test results through the user end requires data to be transmitted through the mobile network, but in the scenario of the nodes to be deployed, the mobile network is poor; the field test equipment of the present application obtains signal quality data directly from the gateway through the LoRa technology, rather than using other communication means such as 4G and other communication technologies to obtain signal quality data from the server. Compared with other communication means, the LoRa signal has a wide coverage range and strong anti-interference ability. LoRa signals are used for interaction throughout the entire process of signal testing, which effectively improves data transmission efficiency and reduces the requirements for environmental communication signals.

[0110] In some embodiments, Figure 4 As shown, a signal testing method is provided, which is applied to Figure 1 Taking the gateway in as an example, the above method includes:

[0111] S402, receiving an uplink test message sent by a field test device; the uplink test message is sent by the field test device to the gateway at the current test location in response to a test instruction.

[0112] Specifically, when the field test device is at the current test position, the tester triggers a test instruction on the field test device, and the field test device responds to the test instruction and sends an uplink test message to the gateway at the current test position; the gateway receives the uplink test message sent by the field test device.

[0113] S404, sending the received uplink test message to a server; the server is a cloud server or a built-in server of a gateway;

[0114] Specifically, the gateway determines uplink signal quality data according to the received uplink test message, where the uplink signal quality data includes at least one of an uplink packet loss rate, an uplink signal strength, or an uplink signal-to-noise ratio.

[0115] After receiving the uplink test message, the gateway may send the uplink test message to a server, which may be a cloud server or a built-in server of the gateway.

[0116] The gateway is configured with a data acquisition plug-in, which enables the gateway to have the ability to obtain data from the server, and then the gateway can obtain uplink signal quality data from the server.

[0117] S406, capturing an uplink test message transmitted uplink to the server from the server, and determining uplink signal quality data according to the captured uplink test message.

[0118] The gateway may capture the uplink test message that is uplinked to the server from the server, and calculate the uplink signal quality data based on the captured uplink test message.

[0119] It should be noted that the number of uplink test messages can be one or more. When the field test equipment is in the current test position, multiple uplink test messages can be sent to the gateway in sequence. Each of the multiple uplink test messages will carry sequence number information, so that the gateway or server can calculate the uplink packet loss rate based on the sequence number information of the received uplink test message. The uplink signal quality data can be the packet loss rate or other common signal quality parameters in the LoRa field.

[0120] In one implementation, a preset number of messages can be set. For ease of description, the preset number of messages is recorded as N. When the number of uplink test messages received by the gateway is less than or equal to N, the current uplink packet loss rate is calculated based on the uplink test messages less than or equal to N; when the number of uplink test messages received by the gateway exceeds N, the real-time uplink packet loss rate can be calculated based on the most recently received N test messages.

[0121] In another implementation, the gateway may calculate the current uplink packet loss rate in real time based on all uplink test messages currently received.

[0122] In another implementation, the field test device may send multiple uplink test messages to the gateway in sequence until the number of uplink test messages sent reaches a message number threshold and stops sending. After the field test device stops sending uplink test messages, the gateway calculates the uplink packet loss rate based on the received uplink test messages.

[0123] S408, encapsulate the uplink signal quality data into a downlink message, and send the downlink message to the field test equipment, so that the field test equipment obtains the uplink signal quality data of the field test equipment at the current test position based on the downlink message sent by the gateway, and displays the first signal test result based on the signal quality data of the current test position in response to the first result display instruction; the signal quality data includes uplink signal quality data.

[0124] Specifically, the gateway encapsulates the uplink signal quality data into a downlink message, sends the downlink message to the field test equipment, and the field test equipment receives the downlink message and extracts the uplink signal quality data through the downlink message.

[0125] The field test equipment displays the first signal test result according to the signal quality data of the current test location in response to the first result display instruction.

[0126] In some embodiments, the field testing device may also obtain signal quality data of the field testing device at multiple test locations in response to a second result display instruction; obtain labels associated with the signal quality data of the multiple test locations respectively; and display a second signal test result based on the signal quality data and labels of the multiple test locations.

[0127] In some embodiments, the signal testing method also includes receiving instructions for testing downlink signal quality sent by the field test equipment, and sending the instructions for testing downlink signal quality to the server; capturing instructions for testing downlink signal quality from the server, and then, based on the instructions for testing downlink signal quality, the gateway sends a downlink test message to the field test equipment, so that the field test equipment calculates the downlink signal quality data based on the received downlink test message.

[0128] Specifically, the field test equipment sends an instruction for testing the downlink signal quality to the gateway, the gateway receives the instruction for testing the downlink signal quality sent by the field test equipment, and sends the instruction for testing the downlink signal quality to the server. The gateway captures the instruction for testing the downlink signal quality from the server, and sends a downlink test message to the field test equipment. The field test equipment calculates the downlink signal quality data according to the downlink test message.

[0129] The downlink signal quality data may include at least one of downlink signal strength, downlink signal-to-noise ratio, or downlink packet loss rate.

[0130] In one possible manner, the uplink test message sent by the field test equipment is encapsulated with the downlink signal quality data of the previous round, and the gateway can extract the downlink signal quality data of the previous round based on the received uplink test message; accordingly, after the field test equipment determines the downlink signal quality data of the current round, the downlink signal quality data of the current round can also be sent to the gateway through the uplink test message, and then the gateway can obtain the uplink signal quality data and downlink signal quality data of the current round, so that the uplink signal quality data and downlink signal quality data of each test location can be viewed through the gateway later.

[0131] In actual applications, there is a situation where the gateway sends data to the field test equipment. Therefore, when testing the signal, adding the test of the downlink signal quality data can improve the comprehensiveness and accuracy of the signal test. In the above embodiment, the uplink signal quality data and the downlink signal quality data can fully reflect the signal quality of the link between the gateway and the field test equipment, thereby improving the accuracy of the signal test.

[0132] In the above embodiment, after receiving the uplink test message, the gateway can calculate the uplink signal quality data according to the built-in server, or obtain the uplink signal quality data calculated by the cloud server, encapsulate the uplink signal quality data into the downlink message, and send the downlink message to the field test equipment to send the uplink signal quality data to the field test equipment. Since the gateway and the field test equipment communicate through the LoRa signal, the field test equipment does not need to rely on other communication means to obtain the uplink signal quality data (for example, communicate with the server through WIFI, 4G, 5G and other technologies to obtain the uplink signal quality data calculated by the server). Compared with other communication means, the LoRa signal has a wide coverage range and strong anti-interference ability. The LoRa signal is used for interaction throughout the entire process of signal testing, which effectively improves the data transmission efficiency and reduces the requirements for environmental communication signals.

[0133] It should be noted that, in the signal testing method, the specific process performed by the field testing device and the process of interaction between the field testing device and the gateway can refer to the description of the embodiment of the above-mentioned signal testing method applied to the field testing device.

[0134] In the signal testing method provided in the embodiment of the present application, the field test equipment sends an uplink test message to the gateway, and the gateway determines the uplink signal quality data according to the uplink test message. The field test equipment receives the downlink message sent by the gateway, and obtains the uplink signal quality data of the field test equipment at the current test position according to the downlink message. The field test equipment responds to the first result display instruction and displays the first signal test result based on the uplink signal quality data of the current test position.

[0135] In the related art, nodes and gateways are required to send test data to the server, which calculates the test results and sends them to the user end, and the test personnel view the test results through the user end; in the present application, signal testing is achieved only through the interaction between the field test equipment and the gateway, and the test results are viewed on the field test equipment. There is no need to interact with the server and the user end, which reduces the communication overhead of the signal test and enables instant viewing of the test results; and viewing the test results through the user end requires data to be transmitted through the mobile network, but in the scenario of the nodes to be deployed, the mobile network is poor; the field test equipment of the present application obtains signal quality data directly from the gateway through the LoRa technology, rather than using other communication means such as 4G and other communication technologies to obtain signal quality data from the server. Compared with other communication means, the LoRa signal has a wide coverage range and strong anti-interference ability. LoRa signals are used for interaction throughout the entire process of signal testing, which effectively improves data transmission efficiency and reduces the requirements for environmental communication signals.

[0136] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0137] In some embodiments, Figure 5 As shown, a signal testing system is provided, including: a field testing device 501 and a gateway 502;

[0138] The field test device 501 is used to send an uplink test message to the gateway at the current test location in response to the test instruction;

[0139] The gateway 502 is used to receive the uplink test message sent by the field test equipment, and send the received uplink test message to the server; the server is a cloud server or a built-in server of the gateway;

[0140] The gateway 502 is used to capture the uplink test message from the server to the server, determine the uplink signal quality data according to the captured uplink test message, encapsulate the uplink signal quality data into the downlink message, and send the downlink message to the site test equipment;

[0141] The field test device 501 is also used to obtain the uplink signal quality data of the field test device at the current test position based on the downlink message sent by the gateway, and to display the first signal test result based on the uplink signal quality data of the current test position in response to the first result display instruction.

[0142] Among them, the field test equipment can execute the above-mentioned signal test method, and the gateway can also execute the above-mentioned signal test method. The specific process executed by the field test equipment can refer to the implementation example of the above-mentioned signal test method; the specific process executed by the gateway can also refer to the implementation example of the above-mentioned signal test method, which will not be repeated here.

[0143] In one possible embodiment, the gateway includes a first LoRa communication unit, a second LoRa communication unit and a computing unit, the first LoRa communication unit is used to receive a LoRa signal from a field test device, and the second LoRa communication unit is used to send a LoRa signal to the field test device; it should be noted that both the uplink test message and the downlink message are sent in the form of a LoRa signal.

[0144] The calculation unit is used to determine the uplink signal quality; in actual applications, the calculation module can also calculate the distance between the test distance where the field test equipment is located and the gateway, which can be used as a reference for adjusting the relative distance between the gateway and the field test equipment; the calculation module can also be used to save signal quality data and associated tags, and can also provide a function for downloading signal quality data.

[0145] The field test equipment may include a communication unit, a device processing unit and a device storage unit; the communication unit is used to receive LoRa signals from the gateway, and can also be used to send LoRa signals to the gateway, for example, it can be used to send uplink test messages to the gateway, and can receive downlink messages sent by the gateway or downlink test messages sent by the gateway.

[0146] The device processing unit can be used to obtain the received downlink message from the communication unit and obtain the uplink signal quality data according to the downlink message; it can also be used to obtain the received downlink test message from the communication unit to determine the downlink signal quality data. For the obtained uplink or downlink signal quality data, the device processing unit can also calculate the average value of multiple quality data, and can also perform data screening and cleaning, etc., and can also modify the configuration of the field test equipment, such as modifying the LoRa radio frequency parameters, wireless connection mode, etc.

[0147] The device storage unit is used to store data, such as data calculated by the device processor, such as uplink signal quality data and downlink signal quality data, as well as labels, calculated average values, and configuration parameters, such as LoRa radio frequency parameters, wireless connection methods, etc.

[0148] The field testing equipment may be provided with an interactive unit, which is used to interact with the tester, such as displaying a UI interface through an interactive module. The tester may use the UI interface to browse the test results and trigger instructions through the UI interface, such as test instructions, first result display instructions, second result display instructions, etc. The first signal test results and the second signal test results may also be displayed through the UI interface. The configuration parameters of the field testing equipment may also be displayed through the interactive module.

[0149] In some embodiments, a signal testing system may be used to implement the above signal testing method, including:

[0150] When the field test equipment is in the current test position, the field test equipment can be configured with input and output components and / or display components. The input and output components and / or display components can be a touch screen. A UI interface is displayed on the touch screen, and the tester can trigger the test instructions through the UI interface. The field test equipment can also be configured with physical buttons, and the tester can trigger the test instructions through the physical buttons.

[0151] The field testing equipment responds to the test instruction and obtains the label corresponding to the current test location, and the label may include location information; specifically, the field testing equipment can obtain the location information of the current test location through the GPS module, and use the location information as the label. When the field testing equipment cannot obtain the location information of the current test location through the GPS module, the location information of the current test location can also be input, such as inputting: Conference Room 001, that is, Conference Room 001 is the label of the current test location; the longitude and latitude of the current test location can also be obtained through other means, and the longitude and latitude can be used as the label of the current test location.

[0152] It should be noted that if the current test location has already undergone a signal test (this is not the first time a signal test has been performed on the current test location), there may be a historical tag for the current test location in the site test equipment (the tag set during the previous test). The historical tag of the current test location can be used as the tag for this signal test. There is no need to obtain the location information of the current test location through the GPS module, or to enter the location information.

[0153] After determining the tag of the current test location, the field test device sends an uplink test message to the gateway. Specifically, the uplink test message may include multiple test data packets, and the time interval between two adjacent test data packets sent may be a preset interval; the number of test data packets included in the uplink test message may be set according to actual needs, such as 50, or there may be no limit on the number, and the message is sent to the field test device to receive the user-input stop test instruction; the preset interval may be set according to actual needs, such as the preset interval may be a time interval selected from 6s to 3600s.

[0154] After receiving the uplink test message sent by the field test equipment each time, the gateway sends the received uplink test message to the server; the server is a cloud server or a built-in server of the gateway; then, the gateway captures the uplink test message from the server to the server, and determines the uplink signal quality data based on the captured uplink test message. The uplink signal quality data may include one or more of the following uplink packet loss rate, uplink signal strength and uplink signal-to-noise ratio, etc. The uplink signal quality data is encapsulated into a downlink message, and the downlink message is sent to the field test equipment.

[0155] The field test equipment receives the downlink message and can extract the uplink signal quality data, so as to display the uplink signal quality data according to the instruction input by the user.

[0156] The field test device can also receive a user-input instruction for testing downlink signal quality data, so that the field test device sends the instruction for testing downlink signal quality data to the gateway, so that the gateway sends a downlink test message to the field test device based on the instruction for testing downlink signal quality data.

[0157] The gateway sends a downlink test message to the field test equipment based on the instruction for testing the downlink signal quality data. The gateway sends the instruction to the server, which can be a cloud server or a server built into the gateway. The gateway captures the instruction for testing the downlink signal quality data from the server, and sends the downlink test message to the field test equipment based on the instruction, so that the field test equipment can determine the downlink signal quality data based on the received downlink test message. The downlink signal quality data may include one or more of the following: downlink packet loss rate, downlink signal strength, downlink signal-to-noise ratio, etc.

[0158] After completing the signal test at the current test location, the tester can trigger the first result display instruction through the UI interface of the field test equipment. The field test equipment responds to the first result display instruction and displays the signal quality line chart according to the signal quality data and label of the current test location.

[0159] It can be understood that the signal quality data of the current test location includes the signal quality data corresponding to each of the multiple test moments, and the signal quality data corresponding to each of the multiple test moments are obtained sequentially during the test process. Therefore, the signal quality line graph can be displayed in real time during the test process, that is, the field test equipment obtains the uplink signal quality data and downlink signal quality data of the field test equipment at the current test location based on the received downlink message, and displays the signal quality line graph in real time during the process of receiving the downlink message; in this way, the tester can intuitively understand the signal quality of the current test location during the test and improve the test efficiency.

[0160] The tester can also trigger a second result display instruction through the UI interface of the field test equipment. The field test equipment responds to the second result display instruction, obtains a map of the area to be deployed, and displays a signal quality heat map based on the labels and signal quality data of multiple test locations.

[0161] In practical applications, when a map is not obtained, a signal quality scatter plot can be generated based on the labels and signal quality data of multiple test locations.

[0162] In the signal testing system provided in the embodiment of the present application, the field test equipment sends an uplink test message to the gateway, and the gateway determines the uplink signal quality data according to the uplink test message. The field test equipment receives the downlink message sent by the gateway, and obtains the signal quality data of the field test equipment at the current test position according to the downlink message. The field test equipment responds to the first result display instruction and displays the first signal test result based on the signal quality data of the current test position.

[0163] In the related art, nodes and gateways are required to send test data to the server, which calculates the test results and sends them to the user end, and the test personnel view the test results through the user end; in the present application, signal testing is achieved only through the interaction between the field test equipment and the gateway, and the test results are viewed on the field test equipment. There is no need to interact with the server and the user end, which reduces the communication overhead of the signal test and enables instant viewing of the test results; and, in order to view the test results through the user end, it is necessary to transmit data through the mobile network, and in the scenario of the nodes to be deployed, the mobile network may be poor; the field test equipment and the gateway of the present application interact through the LoRa signal. Compared with the mobile network, the LoRa signal has a wide coverage range and strong anti-interference ability. In the process of displaying signal quality data, except for the communication between the gateway and the cloud server, no other communication means are required. The field test equipment can also obtain signal quality data based on the LoRa technology, which reduces the dependence on other communication means and effectively improves the data transmission efficiency.

[0164] Based on the same inventive concept, an embodiment of the present application also provides a field testing device. The implementation solution for solving the problem provided by the field testing device is similar to the implementation solution recorded in the above method. Therefore, the specific limitations in the field testing device embodiment provided below can refer to the limitations on the signal testing method above, and will not be repeated here.

[0165] In some embodiments, Figure 6 As shown, a field test device 60 is provided, comprising: a first sending module 601, a first processing module 602 and a result display module 603, wherein:

[0166] The first sending module 601 is used to send an uplink test message to the gateway at the current test location in response to the test instruction, so that the gateway determines the uplink signal quality data based on the uplink test message, and sends the downlink message carrying the uplink signal quality data to the site test equipment;

[0167] The first processing module 602 is used to obtain uplink signal quality data of the field test equipment at the current test location based on the downlink message sent by the gateway;

[0168] The result display module 603 is used to display the first signal test result based on the uplink signal quality data of the current test position in response to the first result display instruction.

[0169] In some embodiments, the field testing equipment also includes: a label processing module, used to obtain a label of the current test location; saving the signal quality data of the current test location and the label in association; the signal quality data includes one or more of the following: uplink signal quality data, downlink signal quality data; the type of signal quality data includes one or more of the following: packet loss rate, signal strength, signal-to-noise ratio and transmission rate; the result display module 603 is also used to obtain a label associated with the signal quality data of the current test location; based on the signal quality data and the label of the current test location, display the first signal test result.

[0170] In some embodiments, the result display module 603 is also used to obtain signal quality data of the field test equipment at one or more test locations in response to a second result display instruction; obtain labels associated with the signal quality data of one or more test locations respectively; and display the second signal test result based on the signal quality data and labels of one or more test locations.
