For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.

Referring to fig. 1, the LORA frequency band testing apparatus includes a control unit 21, a master unit 22, and at least one slave unit 23, where the master unit 22 and the slave unit 23 are installed in the same testing area.

A control unit 21, configured to configure test parameters for the host unit 22; the master unit 22 is configured to receive a registration request of the slave unit 23 after the test is started, perform registration of the slave unit 23, communicate with the registered slave unit 23 through the LORA frequency band according to the test parameters until the test is completed, and record test data corresponding to the LORA frequency band; and the slave unit 23 is used for sending a registration request to the master unit 22 and communicating with the master unit 22 until the test is finished.

It should be noted that the number of the master units 22 is one, the master unit 22 is installed in the center of the test area, the number of the slave units 23 in all the drawings is only schematic, the slave units 23 select the installation number and the installation position according to the distribution area topology, and the principle of installing the slave units 23 is to cover the test area as wide as possible under the condition that the installation number is as small as possible, and to ensure that the distance between two adjacent slave units 23 does not exceed the farthest distance of single-point transmission of the LORA signal.

In a specific embodiment, the control unit 21 comprises a microcontroller, an RS485 communication, a liquid crystal display unit, and a 4 × 4 keyboard, the master unit 22 comprises a microcontroller, a memory, a clock, a standard LORA communication module, an RS485 communication, and a USB interface, and the slave unit 23 comprises a microcontroller, a memory, a clock, and a standard LORA communication module. The control unit 21 communicates with the master unit 22 via RS485, and the master unit 22 communicates with the slave units via LORA. It should be understood that the LORA communication technology has different transmission frequency bands, such as 433MHz, 868MHz, 915MHz, etc., so that different frequency bands can be tested by replacing different types of LORA modules in the master unit 22 and the slave unit 23.

In a specific embodiment, the control unit 21 is further configured to send a export instruction to the host unit 22, the export instruction being configured to export the test data. Specifically, the control unit 21 derives test data from the USB interface of the host unit 22.

In a specific embodiment, the control unit 21 configures the test parameters for the host unit 22, sets the test parameters such as the number of the tested platform area and the test period, and can start the test after configuring the test parameters. The test period is longer than 24 hours, and for the situation that the number of the slave units 23 in the larger area is relatively large, the test period can be increased according to the actual situation, so as to ensure that all the slave units 23 are communicated with the master unit 22 in each period of the test period.

In a specific embodiment, the control unit 21 not only configures the test parameters for the host unit 22, but also the control unit 21 can send a command to the host unit 22 to end the test in advance if the test needs to be ended in advance during the test process; in addition, the control unit 21 may also view the routing information of the slave unit 23, and may also obtain a brief real-time test result.

Referring to fig. 2, in a specific embodiment, the LORA frequency band testing apparatus further includes an analysis unit 24, where the analysis unit 24 is configured to analyze the test data and generate an analysis report, so that the test result is more accurate and intuitive.

Referring to fig. 3, in one embodiment, in order to expand the test area, the LORA frequency band test apparatus supports maximum two-level relay communication, and the slave unit 23 may include a slave 0-level relay 231, a slave 1-level relay 232, and a slave 2-level relay 233. The relay registration procedure is as follows: the master unit 22 reads the neighbor table of the registered slave 0-stage relay 231, and after finding that there is a slave 1-stage relay 232 that has not yet been registered, it will send a registration frame using the slave 0-stage relay 231 as a relay, and after receiving the registration frame, the slave 0-stage relay 231 will forward to the slave 1-stage relay 232, and after receiving the registration frame, the slave 1-stage relay 232 returns a response frame to the slave 0-stage relay 231, and after receiving the response frame, the slave 0-stage relay 231 forwards to the master unit 22, thereby completing registration of the primary route. All communications thereafter from slave level 1 relay 232 to master unit 22 require forwarding from slave level 0 relay 231. After the slave 1 relay 232 is successfully registered, the master unit 22 reads the neighbor table of the slave 1 relay 232, and when finding that there is an unregistered slave 2 relay 233, sends a registration frame to the slave 0 relay 231, the slave 0 relay 231 forwards the registration frame to the slave 1 relay 232, the slave 1 relay 232 forwards the registration frame to the slave 2 relay 233, the slave 2 relay 233 receives the registration frame and returns a response frame to the slave 1 relay 232, and the slave 1 relay 232 forwards the response frame to the slave 0 relay 231, thereby completing the registration of the two relays, and then the communication between the slave 2 relay 233 and the master unit 22 needs to be forwarded by the slave 0 relay 231 and the slave 1 relay 232.

The present application further provides a method for testing an LORA frequency band, referring to fig. 4, the method includes the steps of:

s10, acquiring test parameters and starting a test;

step S20, after the test is started, responding to the registration request of the slave unit, and registering the slave unit;

and S30, communicating with the registered slave units through the LORA frequency band according to the test parameters until the test is finished, and obtaining test data corresponding to the LORA frequency band.

These steps are explained in detail below.

In step S10, test parameters are acquired, and a test is started.

In a specific embodiment, the control unit 21 sets the host unit 22, sets parameters such as the area code to be tested, the test period, and the clock, and starts the test.

In step S20, after the test is started, the slave unit is registered in response to a registration request from the slave unit.

In a specific embodiment, after the test is started, networking is performed first, the slave unit 23 sends a registration request to the master unit 22, the master unit 22 returns a registration frame to the slave unit 23 after receiving the registration request, and the slave unit 23 returns a response frame after receiving the registration frame sent by the master unit 22, that is, the registration is successful.

Continuing to refer to fig. 4, in step S30, the slave unit registered is communicated with the LORA frequency band according to the test parameters until the test is finished, and test data corresponding to the LORA frequency band is obtained.

After the slave unit 23 is registered in step S20, the master unit 22 starts to communicate with the registered slave unit through the LORA frequency band according to the test parameters, and obtains test data corresponding to the LORA frequency band.

In a specific embodiment, the master unit 22 performs a cyclic reading operation on the slave unit 23, and the reading operation includes long packet data and short packet data, each of which includes uplink and downlink signal strengths and a signal-to-noise ratio.

In a specific embodiment, the center frequency of the signal transmitted by the host unit 22 is 433MHz, and it is understood that different frequency bands can be tested by replacing different types of LORA modules in the host unit 22. On the basis of the central frequency point, five different channels are divided, and each channel is tested, so that the noise condition of each time period of the five channels in the 433MHz frequency band in the test period can be tested. The master unit 22 finishes one round of test by reading the slave unit 23 once, and starts the next round of test after the one round of test is finished until the test is finished. The master unit 22 will record and count the communication success rate and real-time signal strength and noise ratio of each slave unit 23 at various time intervals. The noise intensity can be calculated by the signal-to-noise ratio and the signal intensity.

According to the technical scheme, the communication quality conditions of different channels of the test area in different time periods can be reflected more visually by counting the communication success rate of each slave unit 23 in each time period.

Referring to fig. 5, step S30 is preceded by:

step S21, reading a neighbor table of the registered slave unit, and if an unregistered slave unit exists in the neighbor table, sending a registration frame to the registered slave unit so that the registered slave unit forwards the registration frame to the unregistered slave unit;

and step S22, registering the unregistered slave unit according to a response frame returned by the unregistered slave unit.

In this embodiment, in order to expand the test area, the LORA band test apparatus supports relay communication of two levels at maximum, and therefore the slave unit 23 may include a slave 0-level relay 231, a slave 1-level relay 232, and a slave 2-level relay 233. The relay registration process is as follows: the master unit 22 reads the neighbor table of the slave 0-stage relay 231 that has been registered, and after finding that there is a slave 1-stage relay 232 that has not yet been registered, it will send a registration frame with the slave 0-stage relay 231 as a relay, and after receiving the registration frame, the slave 0-stage relay 231 will forward to the slave 1-stage relay 232, and after receiving the registration frame, the slave 1-stage relay 232 returns a response frame to the slave 0-stage relay 231, and after receiving the response frame, the slave 0-stage relay 231 forwards to the master unit 22, and completes the registration of the primary route. All communications thereafter from slave level 1 relay 232 to master unit 22 require the forwarding of slave level 0 relay 231. After the slave 1-stage relay 232 is successfully registered, the master unit 22 reads the neighbor table of the slave 1-stage relay 232, and after finding that there is an unregistered slave 2-stage relay 233, sends a registration frame to the slave 0-stage relay 231, the slave 0-stage relay 231 forwards the registration frame to the slave 1-stage relay 232, the slave 1-stage relay 232 forwards the registration frame to the slave 2-stage relay 233, the slave 2-stage relay 233 receives the registration frame and returns a response frame to the slave 1-stage relay 232, the slave 1-stage relay 232 forwards the response frame to the slave 0-stage relay 231, registration of the two-stage relays is completed, and then communication between the slave 2-stage relay 233 and the master unit 22 needs to be forwarded by the slave 0-stage relay 231 and the slave 1-stage relay 232.

According to the technical scheme, after the control unit configures the test parameters for the host unit and the slave unit registers the host unit, the host unit communicates with the registered slave unit through the LORA frequency band according to the test parameters until the test is finished, and records the test data corresponding to the LORA frequency band, so that the influence of noise on the LORA communication can be accurately reflected; the communication quality is quantitatively evaluated through different angles such as signal strength, noise, communication success rate and the like, so that the test result is more accurate and visual, the test method is convenient and fast, and manual intervention is not needed in the test process.
