Example one
Fig. 2 is a schematic flow chart illustrating an implementation process of a method for detecting a wireless network connection according to an embodiment of the present invention, as shown in fig. 2, the method for detecting a wireless network connection according to the present embodiment includes the following steps:
step 201: configuration information of the router is obtained, and at least one group of testing parameters is generated based on the configuration information.
Here, the configuration information includes, but is not limited to: SSID, password, supported wireless protocol standards, channel, authentication and encryption mode, etc., wherein the wireless protocol standards include but are not limited to: 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, as set by The Institute of Electrical and Electronics Engineers (IEEE).
Here, the test parameters include, but are not limited to: an SSID and a password of the router.
Further, the test parameters include, but are not limited to: the SSID and the password of the router, wherein the SSID and the password can be composed of one or more combinations of numbers, letters, special characters and the like with certain lengths, and the letters are distinguished by case, namely A and a are different letters; the special characters distinguish between Chinese and English, i.e., "? And? "are different special characters. For example, the test parameter may be the following SSID and password combination: SSID 7 digits "1234321", "HR 12321", "HR 1221? "," HR 1221? "or" MEIDIGS ", the corresponding combination may be" 1234567 "," HR12345 "," HR 1234? "," HR 1234? "or" MEIDIGS ", etc., and the number of such combinations can be up to 36 according to the permutation and combination theory. The above combinations of SSID and password are exemplary only and not exhaustive, including but not limited to the above combinations.
Specifically, after the detection device acquires the configuration information of the router, a plurality of sets of test parameters including parameters such as SSID and password are generated according to a preset algorithm, where the SSID is "meidi", and at this time, the password may be "1234567", "HR 12345", "HR 1234? "," HR 1234? Either "or" MEIDIGS "; or the SSID is "HR 12321", in which case the password may be "1234567", "HR 12345", "HR 1234? "," HR 1234? Or "MEIDIGS".
Step 202: selecting a first test parameter from the at least one group of test parameters, encapsulating the first test parameter in a first configuration instruction, and sending the first configuration instruction to the router; the first configuration instruction is used for instructing the router to perform network parameter configuration according to the first test parameter.
In the embodiment of the invention, the detection equipment selects a group of test parameters from the group of test parameters, assumes that the SSID is 'MEIDIGS' and the corresponding password is 'HR 12345', and then packages the SSID and the password into a first configuration instruction; and sending the first configuration instruction to the router, and after receiving the instruction, the router configures the network parameters according to the SSID and the password in the instruction.
Specifically, the sending the first configuration instruction to the router includes: and sending the first configuration instruction to the router through a UART. Here, the UART is used to replace a network cable transmission instruction, such as a first configuration instruction, in order to avoid the problem that the detection device cannot know the state of the router when the router is restarted; and when the network configuration of the router has a problem, the problem that the detection equipment cannot communicate with the router is avoided, so that the detection efficiency of the wireless network connection is improved.
Step 203: after receiving a network parameter configuration success message sent by the router, encapsulating the first test parameter in a first connection instruction, and sending the first connection instruction to a wireless network access module; the first network connection instruction is used for instructing the wireless network access module to access the router according to the first test parameter.
Here, the wireless access module may also be referred to as a WIFI module, and is applied to a household appliance, and is used as a module or a component in the household appliance to connect to a wireless router, so as to implement a corresponding interaction function, such as a mobile phone connected to a network and a certain household appliance, and a user controls the household appliance through the mobile phone. For example, after the air conditioner with the WIFI module is connected to the wireless router, the user can control the air conditioner through software on the mobile phone, for example, in summer, before the user goes home, the user wants to turn on the air conditioner to reduce the indoor temperature, at this time, the software on the mobile phone sends a turn-on command to the air conditioner to turn on the air conditioner and set the temperature of the air conditioner, and when the user goes home, the indoor temperature reaches the appropriate temperature.
Specifically, the sending the first connection instruction to the wireless network access module includes: and sending the first connecting instruction to a wireless network access module through a UART. The wireless network access module may have a certain error rate when monitoring the wireless broadcast information broadcast by the detection device and analyzing the corresponding SSID and password according to the wireless broadcast information, so that the UART is used for transmitting the first network connection instruction instead of the wireless broadcast transmission mode, thereby reducing the error rate and improving the detection effect of the wireless network connection.
Specifically, after the router successfully configures the network parameters according to the SSID and the password in the first test parameter, the router sends a network parameter configuration success message to the detection device, after the detection device receives the network parameter configuration success message sent by the router, the SSID and the password in the first test parameter are encapsulated into a first connection instruction, the first connection instruction is sent to the wireless network access module, and after the wireless network access module receives the first connection instruction, the router is connected according to the SSID and the password in the instruction.
Step 204: and detecting the network connection state of the wireless network access module and the router based on the first test parameter, and judging whether the wireless network access module is successfully accessed to the router based on the network connection state.
Specifically, after sending a first network connection instruction, the detection device sends a detection instruction to the wireless network access module, after receiving the detection instruction, the wireless network access module sends information of a network connection state based on the first test parameter to the detection device, and the detection device judges whether the wireless network access module successfully accesses the router according to the information of the network connection state; or after the wireless network access module is accessed to the router, broadcasting information of the network connection state based on the first test parameter to the detection equipment, and after the detection equipment receives the information, judging whether the wireless network access module is successfully accessed to the router based on the network connection state.
Further, when the wireless network access module is determined to be successfully accessed to the router, a network disconnection instruction is sent to the wireless network access module, and the network disconnection instruction is used for indicating the wireless network access module to disconnect the network connection with the router.
For example, assume that the SSID and password configured by the router are: "MEIDIGS" and "HR 12345" indicate that the test is successful after the wireless network access module is determined to successfully access the router of the SSID and password, the SSID and password need to be replaced for the next test, and before the next test, the connection between the wireless network access module and the router needs to be disconnected.
Further, after receiving the network disconnection state information sent by the wireless network access module, selecting a second test parameter from the at least one group of test parameters, encapsulating the second test parameter in a second configuration instruction, and sending the second configuration instruction to the router; the second test parameter is a parameter that is not selected from the at least one group of test parameters, and the second configuration instruction is used for instructing the router to perform network parameter configuration according to the second test parameter.
Specifically, the sending the second configuration instruction to the router includes: and sending the second configuration instruction to the router through a UART. Here, the UART is used instead of the network line transmission instruction, such as the first configuration instruction, in order to avoid the problem that the detection device cannot know the state of the router when the router is restarted, and to avoid the problem that the detection device cannot communicate with the router when the network configuration of the router is in problem, thereby improving the detection efficiency of the wireless network connection.
Specifically, after receiving the network disconnection status information sent by the wireless network access module, it indicates that the communication connection between the wireless network access module and the router has been disconnected, and the next wireless network connection detection may be performed, at this time, the detection device selects a test parameter that is not selected from the at least one group of test parameters, that is, the second configuration parameter in the embodiment of the present invention. For example, assuming that the number of combinations of the at least one set of test parameters is 6, combine one: "1234321" and "1234567"; combining two: "HR 12321" and "HR 12345"; combining three components: "hr 12321" and "hr 12345"; and (4) combining: "HR 1221? "and" HR 1234? "; and (5) combining: "HR 1221? "and" HR 1234? "; combining six: "MEIDIGS" and "MEIDIGS", wherein the former represents SSID and the latter represents password in the above combination. When the combination one, the combination two and the combination three are all selected and the detection result is successful, the next detection is performed by selecting the combination four, the combination five and the combination six, assuming that the selected combination is the combination four, then the SSID and the password parameter "HR 1221? "and" HR 1234? And encapsulating the configuration data in a second configuration instruction, and sending the second configuration instruction to the router.
Further, after receiving the network parameter configuration success message sent by the router, encapsulating the second test parameter in a second networking instruction, and sending the second networking instruction to a wireless network access module; and the second networking instruction is used for instructing the wireless network access module to access the router according to the second test parameter.
Specifically, the sending the second networking instruction to the wireless network access module includes: and sending the second networking instruction to a wireless network access module through a UART. The wireless network access module monitors the wireless broadcast information broadcast by the detection equipment and analyzes the corresponding SSID and password according to the wireless broadcast information, and a certain error rate is possibly achieved, so that the UART is used for replacing a transmission mode of wireless broadcast to transmit a second networking instruction, the error rate is reduced, and the detection effect of wireless network connection is improved.
And further, detecting the network connection state of the wireless network access module and the router based on the second test parameter, and judging whether the wireless network access module is successfully accessed to the router based on the network connection state. And when the wireless network access module is determined to be successfully accessed to the router, the test is successful by using the test parameters of the combination four, so that the next detection is carried out, and one group is selected from the combination five and the combination six for carrying out the next detection.
Further, when it is determined that the wireless network access module is not successfully connected with the router, a reconnection instruction is sent to the wireless network access module, and the reconnection instruction is used for instructing the wireless network access module to reconnect the router according to the first test parameter. Generally speaking, if a certain group of test parameters are used, if the combined five test is not successful, that is, if the wireless network access module does not successfully access the router with the configuration parameters of the combined five, the detection device sends a reconnection instruction to the wireless network access module after receiving the information that the test is unsuccessful, and instructs the wireless network access module to reconnect the router, and if the connection is still unsuccessful for three times, the detection device judges that the detection of the test parameters using the combination fails; if the connection is successful in three times, the next detection is continued, and if the combination from one to five is selected, the combination from six is selected as a test parameter for detection. It should be noted that the combinations of the detection parameters in the embodiments of the present invention are merely exemplary, and are not exhaustive, and include, but are not limited to, the above six combinations.
Further, after said determining that said wireless network access module successfully accesses said router and said determining that said wireless network access module successfully connects said router, said method further comprises: detecting whether the at least one group of test parameters have unselected parameters; and stopping the connection detection of the wireless network when the selected parameters in the at least one group of test parameters are determined.
Further, the sending a network disconnection command to the wireless network access module includes: and when the unselected parameters in the at least one group of test parameters are determined, sending a network disconnection instruction to the wireless network access module.
Specifically, when all SSID and password combinations are tested successfully, the wireless network connection detection of the round is completed. In the embodiment of the present invention, if the number of the at least one set of test parameters is 6, combine one: "1234321" and "1234567"; combining two: "HR 12321" and "HR 12345"; combining three components: "hr 12321" and "hr 12345"; and (4) combining: "HR 1221? "and" HR 1234? "; and (5) combining: "HR 1221? "and" HR 1234? "; combining six: "meidicgs" and "meidicgs" when these six combinations are selected and the detection is successful, the current round of wireless network connection detection is stopped. If the other parameters need to be tested, the tester modifies the corresponding test case and continues to test according to the method.

"," HR 1234? Either "or" MEIDIGS "; or the SSID is "HR 12321", in which case the password may be "1234567", "HR 12345", "HR 1234? "," HR 1234? Or "MEIDIGS".

Further, when it is determined that the wireless network access module successfully accesses the router, the second sending unit 309 sends a network disconnection instruction to the wireless network access module, where the network disconnection instruction is used to instruct the wireless network access module to disconnect the network connection with the router.
For example, assume that the SSID and password configured by the router are: "MEIDIGS" and "HR 12345" indicate that the test is successful after the wireless network access module is determined to successfully access the router of the SSID and password, the SSID and password need to be replaced for the next test, and before the next test, the connection between the wireless network access module and the router needs to be disconnected.

"; combining six: "MEIDIGS" and "MEIDIGS", wherein the former represents SSID and the latter represents password in the above combination. When the combination one, the combination two and the combination three are all selected and the detection result is successful, the next detection is performed by selecting the combination four, the combination five and the combination six, assuming that the selected combination is the combination four, then the SSID and the password parameter "HR 1221? "and" HR 1234? "is encapsulated in a second configuration instruction, and the second sending unit 309 sends the second configuration instruction to the router.

Further, the second detecting unit 312 detects a network connection status of the wireless network access module and the router based on the second test parameter, and the second determining unit 313 determines whether the wireless network access module successfully accesses the router based on the network connection status. And when the wireless network access module is determined to be successfully accessed to the router, the test is successful by using the test parameters of the combination four, so that the next detection is carried out, and one group is selected from the combination five and the combination six for carrying out the next detection.
Further, when it is determined that the wireless network access module is not successfully connected to the router, the third sending unit 314 sends a reconnection instruction to the wireless network access module, where the reconnection instruction is used to instruct the wireless network access module to reconnect to the router according to the first test parameter.
