[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the first aspect, an embodiment of the present invention provides a method for detecting smart home appliances on an assembly line. The method is implemented based on a detection device, the detection device includes a test computer, a code scanning device connected to the test computer, an infrared module connected to the test computer, and an infrared probe connected to the infrared module; the method is executed by an electric control module on the smart home appliance, see Figure 1 and Figure 2 , the method includes S110 to S130:

[0025] S110, after the smart home appliance is powered on, detecting whether the communication serial port between the electric control module and the WIFI module in the smart home appliance is normal and whether the radio frequency performance of the WIFI module is normal;

[0026] S120, if the communication serial port is normal and the radio frequency performance is normal, then receive the infrared signal emitted by the infrared probe, extract the SN information from the infrared signal, and write the SN information into the WIFI module; wherein the barcode scanning device is used to obtain the SN information under the scanning operation of the SN barcode label of the smart home appliance by the personnel, and send the SN information to the test computer; the test computer is used to: after obtaining the SN information, send the SN information to the infrared module through the serial port, so that the infrared module converts the SN information into an infrared signal, and transmits the infrared signal to the electric control module of the smart home appliance through the infrared probe;

[0027] S130: After the writing operation is performed, the smart home appliance is controlled to start up, and the detection result is displayed on the display panel of the smart home appliance.

[0028] It is understandable that multiple smart home appliances are tested one by one on the assembly line, and a set of testing equipment is configured for one assembly line, including a test computer, a code scanning device, an infrared module, and an infrared probe. Among them, the code scanning device and the infrared module are both connected to the test computer, and the infrared module is connected to the test computer through a serial port, and the infrared probe is connected to the infrared module.

[0029] Among them, the SN information is the serial number.

[0030] In actual scenarios, when a smart home appliance passes through the assembly line and reaches the staff's inspection station, it starts to power on. After the smart home appliance is powered on, it will perform a self-test. The self-test items mainly include: checking whether the communication serial port between the electric control module and the WIFI module in the smart home appliance is normal, and whether the radio frequency performance of the WIFI module is normal. Only after the self-test items are passed will the subsequent SN information writing operation be performed. If the self-test items pass, even if the write operation is performed, there is a high probability that the write will fail.

[0031] At the same time, when a smart home appliance passes through the assembly line and reaches the staff's inspection station, the staff also uses a barcode scanning device to scan the SN barcode label of the smart home appliance. After the barcode scanning device obtains the SN information in the SN barcode label, it sends the SN information to the test computer. The test computer sends the SN information to the infrared module through the serial port. The infrared module converts the SN information into an infrared signal, and the infrared signal is emitted through the infrared probe. Since the position of the infrared probe is just aimed at the electronic control module of the smart home appliance, the electronic control module will obtain the infrared signal.

[0032] When the electronic control module obtains the infrared signal, it analyzes the infrared signal, extracts the SN information in the infrared signal, and then writes the SN information into the WIFI module. After the write operation is completed, the smart home appliance is turned on. At this time, the display panel of the smart home appliance is lit, and the corresponding detection result can be displayed on the display panel according to the success or failure of the write operation.

[0033] In one embodiment, the detecting whether the communication serial port between the electric control module and the WIFI module in the smart home appliance is normal may specifically include:

[0034] Whether the communication serial port between the electric control module and the WIFI module in the smart home appliance is normal is detected by means of heartbeat communication.

[0035] Among them, heartbeat communication means that the electronic control module sends a data packet to the WIFI module at regular intervals, and judges whether the communication serial ports of the two are normal by the reply of the WIFI module. It is a very reliable and convenient detection method to judge whether the communication serial ports between the two are normal by heartbeat communication.

[0036] In one embodiment, in order to facilitate the detection of whether the radio frequency performance of the WIFI module is normal, the detection device also includes a test router. Correspondingly, the detection of whether the radio frequency performance of the WIFI module is normal may specifically include:

[0037] Obtaining the signal strength value and router name of the test router to which the WIFI module is connected; wherein the WIFI module automatically searches for and connects to the test router in the environment after being powered on;

[0038] If the signal strength value is greater than the signal threshold in the router name, it is determined that the radio frequency performance of the WIFI module is normal.

[0039] That is to say, when powered on, the WIFI module will automatically search for the test router in the environment and connect to the test router with the strongest signal strength. The electronic control module will obtain the router name and signal strength value of the test router to which the WIFI module is connected from the WIFI module. The signal threshold will be pre-configured in the router name. If the signal strength value is greater than the signal threshold, it means that the RF performance of the WIFI module is normal. If the signal strength value is less than or equal to the signal threshold, it means that the RF performance of the WIFI module is abnormal. It can be seen that this method can quickly detect whether the RF performance of the WIFI module is normal.

[0040] In one embodiment, the test computer is installed with host computer detection software, and the test computer is also used to: after sending the SN information to the infrared module, display whether the SN information is generated successfully through the host computer detection software.

[0041] That is to say, the host computer detection software is installed on the test computer, and the host computer detection software sends the SN information to the infrared module through the serial port of the computer, and then displays whether the SN signal is successfully sent to the infrared module. That is, the test computer does not display the final test result, but only displays whether the SN signal is successfully sent to the infrared module. After the test computer sends the SN information to the infrared module, the process of the host computer ends here, which makes the processing process of the host computer detection software short in time and high in stability.

[0042] If the information displayed on the test computer is "SN signal sent to infrared module successfully", the staff at the testing station will not intercept the smart home appliance. When the smart home appliance detection is completed, the test results will be displayed on the display panel. At this time, the smart home appliance will dynamically flow to another testing station. After the staff at the station sees the test results from the display panel, if the test passes, the smart home appliance will continue to flow. If the test is abnormal, different treatments will be carried out according to different abnormal situations.

[0043] In one embodiment, extracting the SN information from the infrared signal and writing the SN information into the WIFI module may specifically include:

[0044] Extract SN information from the infrared signal and write the SN information into the flash memory in the electric control module; send the SN information in the flash memory in the electric control module to the WIFI module through the communication serial port between the electric control module and the WIFI module, so that the WIFI module writes the received SN information into the flash memory in the WIFI module.

[0045] That is to say, the extracted SN signal is first written into the flash memory of the electric control module, and then the SN information is sent to the WIFI module through the serial port between the electric control module and the WIFI module, and the WIFI module writes the SN information into the flash memory of the WIFI module. In this way, when writing to the flash memory of the WIFI module fails, the SN information can be obtained again from the flash memory of the electric control module and written into the flash memory of the WIFI module again. After multiple failures in writing to the flash memory of the WIFI module, the writing is stopped, and it is considered that the operation of writing to the flash memory of the WIFI module has failed.

[0046] In one embodiment, displaying the detection result on the display panel of the smart home appliance may specifically include at least one of the following:

[0047] (1) If the SN information is not successfully written into the flash memory in the electronic control module, the detection result displayed on the display panel is "the SN information fails to be written into the electronic control module";

[0048] That is to say, if the step of writing the SN information into the flash memory of the electronic control module fails, the detection result displayed on the display panel is that the writing of the SN information into the electronic control module fails, so the staff will know that the writing failure is caused by factors of the electronic control module itself.

[0049] (2) If the SN information is not successfully written into the flash memory in the WIFI module, the detection result displayed on the display panel is "the SN information fails to be written into the WIFI module";

[0050] That is to say, if the step of writing the SN information into the flash memory of the WIFI module fails, the detection result displayed on the display panel is that the SN information fails to be written into the WIFI module, so the staff will know that the writing failure is caused by factors of the WIFI module itself.

[0051] (3) If the SN information is successfully written into the flash memory in the WIFI module, the detection result displayed on the display panel is "the detection of the WIFI module is successful".

[0052] That is to say, if the SN information is successfully written into the flash memory of the WIFI module, it means that the previous operations are also successfully executed. At this time, the entire detection process for the WIFI module is successful, so the detection result displayed on the display panel is that the detection of the WIFI module is successful.

[0053] It can be seen that different test results are displayed on the display panel, which makes it easier for staff to locate the cause of the abnormality and then take different measures.

[0054] In one embodiment, the method provided by the embodiment of the present invention may further include:

[0055] If it is determined that the communication serial port between the electric control module and the WIFI module in the smart home appliance is abnormal, the smart home appliance is controlled to start up, and a detection result is displayed on the display panel of the smart home appliance as "the communication serial port between the electric control module and the WIFI module is abnormal";

[0056] Alternatively, if it is determined that the radio frequency performance of the WIFI module is abnormal, the smart home appliance is controlled to start up, and the detection result "the radio frequency performance of the WIFI module is abnormal" is displayed on the display panel of the smart home appliance.

[0057] That is to say, when the communication serial port between the electronic control module and the WIFI module is abnormal or the radio frequency performance of the WIFI module is abnormal, although the operation of writing SN information to the WIFI module will not be executed, the smart home appliances will be turned on, which makes it easier to display the test results on the display panel, so that the staff can know the cause of the abnormality.

[0058] It can be seen that five types of detection results can be displayed on the display panel: successful detection of the WIFI module, failure to write the SN information to the electric control module, failure to write the SN information to the WIFI module, abnormality of the communication serial port between the electric control module and the WIFI module, and abnormality of the radio frequency performance of the WIFI module. In this way, the staff can screen out the smart home appliances that have failed or are abnormal in detection according to the detection results displayed on the display panel and take relevant measures.

[0059] The smart home appliance in the embodiment of the present invention includes a display panel, an electric control module and a WIFI module, and the electric control module is the MCU of the smart home appliance.

[0060] Among them, the SN tag is a material in the equipment assembly process. Before the test, the SN information corresponding to the SN tag has not been written into the WiFi module. After successfully writing into the WiFi module, the SN information will be used as the unique identifier of the smart home appliance. The host computer detection software obtains the SN information corresponding to the SN tag through the code scanning device, and sends the SN information to the infrared module through the serial port. After receiving the SN information, the infrared module returns the receiving result to the host computer detection software, and the host computer detection software displays this result. At this point, the process of testing the computer ends. It can be seen that the process of testing the computer is short in time and highly stable.

[0061] Among them, after receiving the SN information sent by the host computer detection software, the infrared module converts the SN information into an infrared signal, and sends the infrared signal to the electric control module of the smart home appliance through the infrared probe. At this time, please note: the staff only needs to aim the infrared probe at the smart home appliance, and the process of sending the infrared signal point-to-point to the electric control module of the smart home appliance is also reliable.

[0062] Among them, smart home appliances enter the self-test phase from the moment they are powered on. After the self-test is successful, they receive point-to-point infrared signals, perform the SN information writing operation, obtain the test results, turn on the power, and synchronize the test results to the display panel in a timely manner.

[0063] In the prior art, in order to detect the smart home appliances on the assembly line, a test computer and a test router are configured, and the test computer is installed with host computer detection software and a wireless network card. The wireless network card is connected to the test router, and the WIFI module is connected to the test router after the smart home appliance is powered on. At this time, the test computer and the WIFI module are in the same local area network. The SN label and MAC label of the smart home appliance are scanned and uploaded to the host computer detection software through a code scanning device. The host computer detection software packages UDP data, which contains SN and MAC information, and then broadcasts the UDP data. The WiFi modules of each smart home appliance in the same local area network can receive the UDP data. The WIFI module of a smart home appliance matches the SN information corresponding to its own MAC information, and then performs the SN information write operation. The host computer detection software then displays the test results.

[0064] It can be seen that in the prior art, a wireless network card needs to be installed on the test computer, so that the test computer, the test router and the WIFI module of the smart home appliance are all in the same local area network, and the SN information corresponding to each MAC tag is broadcast through the local area network. In the embodiment of the present invention, an infrared module and an infrared probe are added, and the infrared module is connected to the test computer through a serial port. The SN information is converted into an infrared signal through the infrared module, and the infrared signal is transmitted to the corresponding electronic control module of the smart home appliance. It can be seen that in the embodiment of the present invention, the test computer does not need to establish a connection relationship with the test router, so there is no need to install a wireless network card on the test computer, and the serial port communication method is more reliable than the local area network method, because serial port data communication is much more reliable than UDP network data communication. UDP network data communication is easily affected by the network environment and packet loss occurs, while serial port data communication does not have this phenomenon. Since the method provided by the embodiment of the present invention does not require the installation of a wireless network card in the test computer, nor does it require the acquisition of the MAC tag of the smart home appliance, the overall detection efficiency is also improved.

[0065] That is to say, in the embodiment of the present invention, the smart home appliance is mobile, and the host computer detection software on the test computer sends the SN information to the infrared module through the serial port, so that the infrared module can obtain the SN information in real time. Since the communication is through the serial port, this method is not affected by the network environment, and the problem of the detection rhythm of the entire assembly line being disrupted due to network delay is avoided. For the staff working on the detection, they can scan the code while aiming the infrared probe at the smart home appliance point by point.

[0066] In the prior art, the final test results need to be displayed on the host computer detection software, which is time-consuming and easily affected by network delays. In the embodiment of the present invention, the test results of the host computer detection software only reflect whether the SN signal is successfully sent to the infrared module, so that the host computer detection software takes less time to display the results, has high stability, and can meet the normal production rhythm.

[0067] In an embodiment of the present invention, various test results are displayed on the display panel. When the smart home appliance flows to a certain test station, the staff at the station can see the test results, allowing the staff to analyze the cause of the abnormality, which is conducive to the staff to perform different processing according to different test results, which is flexible and convenient.
