As known from the background art, for a sensor having two communication modes of Long Range Radio (LoRa) and bluetooth, a manual test mode is generally used to test the function of the sensor. However, the manual test sensor requires a lot of labor and time, and has a long test cycle and high test cost.
Accordingly, an embodiment of the present utility model provides a sensor automation test system including: the system comprises a sensor to be tested, a Bluetooth test link, a LoRa test link and an upper computer. The upper computer can send a test instruction to the sensor to be tested through the Bluetooth test link and the LoRa test link to perform functional test, so that the test period can be shortened, and the test cost can be reduced.
Referring to fig. 1, fig. 1 shows a schematic structural diagram of a sensor automation testing system according to an embodiment of the present utility model, where the sensor automation testing system includes: sensor to be tested 100, bluetooth test link 200, loRa test link 300, host computer 400.
Specifically, a first end of the sensor 100 to be tested is connected to the upper computer 400 through the bluetooth test link 200, and a second end of the sensor 100 to be tested is connected to the upper computer 400 through the LoRa test link 300.
More specifically, the first end of the sensor 100 to be tested is connected to one end of the bluetooth test link 200 in a bluetooth connection manner, and the other end of the bluetooth test link 200 is connected to the host computer 400.
The second end of the sensor 100 to be tested is connected to one end of the LoRa test link 300 in a LoRa connection manner, and the other end of the LoRa test link 300 is connected to the host computer 400.
When the sensor 100 to be tested is tested, the upper computer 400 sends a first test instruction to the sensor 100 to be tested through the bluetooth test link 200 to perform a corresponding functional test, and the upper computer 400 sends a second test instruction to the sensor 100 to be tested through the LoRa test link 300 to perform a corresponding functional test.
It should be noted that, the first test instruction may be a configuration instruction or a read instruction; when the first test instruction is a read instruction, the signal parameters input to the sensor 100 to be tested are simulated in advance according to the technical protocol document of the sensor 100 to be tested and the signal source, so as to pre-determine the expected data finally uploaded by the sensor 100 to be tested (for example, pre-determine which range of values the uploaded message data should be). After the upper computer 400 sends the read instruction (i.e., the first test instruction) to the sensor 100 to be tested through the bluetooth test link 200, the sensor 100 to be tested sends uplink data to the upper computer 400, and the upper computer 400 determines whether the uplink data sent by the sensor 100 to be tested is desired data; if yes, the function test of the first test instruction sent at this time passes (corresponding to test pass), and if not, the function test of the first test instruction sent at this time does not pass (corresponding to test fail).
For example: after the upper computer 400 sends the read instruction to the sensor 100 to be tested through the bluetooth test link 200, the sensor 100 to be tested sends uplink data to the upper computer 400, and the upper computer 400 judges whether the value of the uplink data sent by the sensor 100 to be tested is within the range predicted; if the detected frequency is within the preset range, the pass is judged, and if the detected frequency is not within the preset range, the fail is judged.
The second test instruction may be a configuration instruction, after the upper computer 400 sends the configuration instruction to the sensor 100 to be tested through the LoRa test link 300, the sensor 100 to be tested will send uplink information to the upper computer 400 at a specified interval time, and the upper computer 400 determines whether the test is passed or not by judging the uplink information; the specific manner in which the upper computer 400 determines the uplink information can be referred to the above description about "whether the uplink data sent by the sensor 100 to be tested is the desired data" by the upper computer 400, which is not described herein.
In the embodiment of the present utility model, the upper computer 400 may send a test instruction to the sensor 100 to be tested through the bluetooth test link 200 and the LoRa test link 300 to perform a functional test, and may test the bluetooth test link 200 and the LoRa test link 300 at the same time, thereby shortening the test period and reducing the test cost.

When the upper computer 400 sends the first test instruction, the upper computer 400 sends the first test instruction to the bluetooth gateway 201 through the first server 202, and the bluetooth gateway 201 sends the first test instruction to the sensor 100 to be tested through bluetooth communication.
Similarly, when the sensor to be tested 100 transmits uplink data to the upper computer 400, the sensor to be tested 100 transmits the uplink data to the first server 202 through the bluetooth gateway 201, and the first server 202 transmits the uplink data to the upper computer 400.
In some embodiments, as a further structural schematic of a sensor automation test system provided in fig. 3, the LoRa test link 300 includes a LoRa gateway 301 and a second server 302.

The automated test tool 401 sends a first test instruction to the sensor 100 under test via the bluetooth test link 200 for performing a corresponding functional test, and the automated test tool 401 sends a second test instruction to the sensor 100 under test via the LoRa test link 300 for performing a corresponding functional test.
After the automated test tool 401 sends the test instruction to the sensor under test 100, the automated test tool 401 determines whether the test passes by the data uploaded by the sensor under test 100.
In some embodiments, as shown in fig. 5, a further structural schematic diagram of a sensor automation test system is provided, where the host computer 400 further includes a client 402;

The client 402 mainly has functions of monitoring and debugging, etc., and the client 402 can be used to determine whether the bluetooth test link 200 and the LoRa test link 300 are normal.
In some embodiments, as shown in FIG. 6, which provides a further structural schematic diagram of a sensor automation test system, the first server 202 may be an MQTT server, the second server 302 may be a LoRa server, and the client 402 may be an MQTT client.
It should be noted that MQTT is message queue telemetry transport (Message Queuing Telemetry Transport).
Fig. 6 includes a sensor 100 to be tested, a bluetooth gateway 201, an MQTT server (i.e., the first server 202 mentioned above), an automated test tool 401, an MQTT client (i.e., the client 402 mentioned above), a LoRa gateway 301, and a LoRa server (i.e., the second server 302 mentioned above);
specifically, a first end of the sensor 100 to be tested is connected with one end of the bluetooth gateway 201, the other end of the bluetooth gateway 201 is connected with one end of an MQTT server, and the other end of the MQTT server is respectively connected with the automated testing tool 401 and the MQTT client;
the second end of the sensor 100 to be tested is connected with one end of the LoRa gateway 301, the other end of the LoRa gateway 301 is connected with one end of the LoRa server, and the other end of the LoRa server is connected with the automated testing tool 401 and the MQTT client respectively.
To better explain how the sensor under test 100 is functionally tested, it is illustrated in connection with the following on the basis of fig. 6.
The sensor 100 to be tested has two communication modes, namely Bluetooth and LoRa, and the upper computer 400 comprises an automatic testing tool 401 and an MQTT client (namely the client 402); the automated test tool 401 is used as a main test execution unit to implement instruction issuing and reading, and the automated test tool 401 is connected to the MQTT server (i.e. the first server 202 mentioned above) and the LoRa server (i.e. the second server 302 mentioned above) respectively through an EtherNet (EtherNet) communication manner.
The automated test tool 401 adopts the mode of the MQTT protocol to subscribe and publish the theme, thereby realizing the transceiving of data.
The function of the MQTT client is mainly that the uplink data of the sensor 100 to be tested are debugged and monitored by a link, and the MQTT client is respectively connected to the MQTT server and the LoRa server in an ETH communication mode. The MQTT client terminal adopts the MQTT protocol to subscribe and publish the theme.
The bluetooth gateway 201 is used as a data transfer transmission tool for the communication between the sensor 100 to be tested and the MQTT server, one end of the bluetooth gateway 201 communicates with the sensor 100 to be tested in a bluetooth mode, and the other end of the bluetooth gateway 201 communicates with the MQTT server in an ETH mode.
The LoRa gateway 301 is used as a data transfer transmission tool for communication between the sensor 100 to be tested and the LoRa server, one end of the LoRa gateway 301 communicates with the sensor 100 to be tested in a LoRa mode, and the other end of the LoRa gateway 301 communicates with the LoRa server in an ETH mode.
At the beginning of the test of the sensor under test 100, the automated test tool 401 connects to the MQTT server and the LoRa server, respectively, as do the MQTT client. The bluetooth gateway 201 is automatically connected to the MQTT server after successful start-up, and the LoRa gateway 301 is automatically connected to the LoRa server after successful start-up.
In the process of testing the sensor to be tested 100, under the bluetooth test link 200, the MQTT client issues a connection instruction to the theme in the manner of MQTT protocol, and at this time, the connection instruction is sent to the MQTT server through an ETH message. Since the bluetooth gateway 201 subscribes to the theme, the MQTT server receives the connection instruction and the bluetooth gateway 201 also receives (or subscribes to) the connection instruction in the theme.
The bluetooth gateway 201 forwards the connection instruction to the sensor 100 to be tested in the bluetooth broadcast mode through bluetooth communication; the sensor to be tested 100 successfully connects to the bluetooth gateway 201 after receiving the connection instruction, and at this time, bluetooth of the sensor to be tested 100 is switched from the broadcast mode to the connection mode. After the bluetooth of the sensor to be tested 100 is switched to the connection mode, the sensor to be tested 100 can perform normal data interaction communication with the bluetooth gateway 201.
The automated test tool 401 issues a first test instruction (a configuration instruction or a read instruction) to the theme, the bluetooth gateway 201 acquires the first test instruction in the theme in the above-mentioned manner, and the bluetooth gateway 201 issues the first test instruction to the sensor 100 to be tested.
When the sensor 100 to be tested receives a reading instruction (when the first testing instruction is the reading instruction), the sensor 100 to be tested sends uplink data to the bluetooth gateway 201, and the bluetooth gateway 201 issues the received uplink data to the theme (can issue the uplink data to the theme through the MQTT server); since the automated test tool 401 also subscribes to the theme, after the bluetooth gateway 201 publishes the received uplink data to the theme, the automated test tool 401 may subscribe to the uplink data in the theme through the MQTT server; the automatic test tool 401 performs the judgment and the storage according to the subscribed uplink data, and the specific judgment process can refer to the above description about "whether the uplink data sent by the sensor 100 to be tested is the desired data" by the upper computer 400, which is not described herein.
Similarly, the MQTT client subscribes to the theme, and after the bluetooth gateway 201 publishes the received uplink data to the theme, the MQTT client may subscribe to the uplink data in the theme through the MQTT server; the MQTT client displays the subscribed uplink data to a specific window in real time.
It should be noted that, the connection mode of the sensor 100 to be tested and the LoRa gateway 301 is mainly that the sensor 100 to be tested has its own function; if the sensor 100 to be tested has an automatic connection function, the sensor 100 to be tested may be automatically connected to the LoRa gateway 301 after both the LoRa gateway 301 and the LoRa server are on-line. If the sensor 100 to be tested does not have the automatic connection function, the MQTT client is required to issue a connection instruction to connect the sensor 100 to be tested to the LoRa gateway 301, and in particular, how to issue a connection instruction to connect the sensor 100 to be tested to the LoRa gateway 301 can be referred to the above description of how to connect the sensor 100 to be tested to the bluetooth gateway 201, which is not repeated here.
Under the LoRa test link 300, the sensor to be tested 100 is connected to the LoRa gateway 301 after being started successfully, and the automated test tool 401 issues a second test instruction (such as a configuration instruction) to the theme by means of the MQTT protocol, where the second test instruction is sent to the LoRa server in the manner of an ETH message. After receiving the second test instruction in the theme, the LoRa server forwards the message of the second test instruction to the LoRa gateway 301 by means of TCP/IP protocol.
The LoRa gateway 301 forwards the second test instruction to the sensor 100 under test by means of LoRa. After the sensor to be tested 100 receives the second test instruction (such as the configuration instruction), the sensor to be tested 100 will send uplink information to the LoRa gateway 301 at a specified interval; the LoRa gateway 301 forwards the received uplink information to the LoRa server. The LoRa server publishes the received uplink information to the topic in the MQTT protocol. The automated test tools 401 subscribe to the uplink information in the topic; the automatic test tool may determine and store the uplink information according to the subscribed uplink information, and the specific determination process may refer to the above description about "the upper computer 400 determines whether the uplink data sent by the sensor 100 to be tested is the desired data" and will not be described herein.
Similarly, the MQTT client subscribes to the topic, and the MQTT client subscribes to the uplink information in the topic through the LoRa server; the MQTT client displays the subscribed uplink information to a specific window in real time.
The above is an exemplary illustration of functional testing of the sensor under test 100; the upper computer 400 may perform a functional test by transmitting a test instruction to the sensor 100 to be tested through the bluetooth test link 200 and the LoRa test link 300, and may simultaneously test the bluetooth test link 200 and the LoRa test link 300, thereby enabling to shorten a test period and reduce a test cost.
In summary, the embodiment of the present utility model provides an automatic sensor testing system, where the upper computer 400 may send a testing instruction to the sensor 100 to be tested through the bluetooth testing link 200 and the LoRa testing link 300 to perform a functional test, so as to shorten the testing period and reduce the testing cost.
