The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

Fig. 1 is a schematic structural diagram of a testing system for a WIFI function provided in a first embodiment of the present invention, and as shown in fig. 1, the testing system for a WIFI function provided in the embodiment of the present invention includes acontrol device 1, awireless testing device 2, and a device undertest 3, where:

thecontrol device 1 is respectively connected with thewireless test device 2 and the testeddevice 3 in a communication mode, and the testeddevice 3 is connected with thewireless test device 2 in a wireless communication mode. Thewireless testing device 2 is used for performing a WIFI function test on the testeddevice 3 in an open airspace.

The WIFI function of the device undertest 3 is tested by testing each frequency band of each antenna of the device undertest 3, and when the test result of each frequency band of each antenna of the device undertest 3 is passed, the device undertest 3 passes the WIFI function test. The working process of the test system for the WIFI function provided in the embodiment of the present invention is described below by taking an example of setting that the device undertest 3 operates in an access point mode (AP mode for short) and testing one frequency band of one antenna of the device undertest 3. When the plurality of antennas of the device undertest 3 correspond to the same frequency band, only one frequency band of one currently tested antenna is enabled, and the other antennas of the same frequency band are turned off.

Thecontrol apparatus 1 sends a first control instruction to the device undertest 3, so that the device undertest 3 operates in the AP mode and configures a unique corresponding Service Set Identifier (SSID) for the device undertest 3. Isolation of the device undertest 3 in the open air is achieved by configuring the device undertest 3 with a unique SSID such that the SSID of each device undertest 3 in the open air is unique. The first control instruction is set according to actual needs, and the embodiment of the present invention is not limited.

Thecontrol device 1 sends a second control command to thewireless testing device 2 to enable thewireless testing device 2 to operate in a station mode (STA mode for short), and enable thewireless testing device 2 to access the set frequency band of the set antenna of the device under test. The second control instruction is set according to actual needs, and the embodiment of the present invention is not limited.

Thewireless test device 2 checks whether to establish a WIFI wireless communication connection with the set frequency band of the set antenna of the device undertest 3, and if the WIFI wireless communication connection is successfully established, returns information of successful connection to thecontrol device 1, and if the WIFI wireless communication connection cannot be established within a specified time, returns information of failed connection to thecontrol device 1.

If thecontrol device 1 receives the connection success information, it will send a third control instruction to the device undertest 3 to make the device undertest 3 send the test information to thewireless test device 2 by wireless communication. Thecontrol apparatus 1 may determine that the test for setting the antenna and setting the frequency band fails if the information of the connection failure is received. The test information may include management frames and control frames, etc., and complies with the ieee e802.11 protocol. The third control instruction is set according to actual needs, and the embodiment of the present invention is not limited.

After receiving the test information in the WIFI communication manner, thewireless test device 2 obtains a test result of the set frequency band of the set antenna of the device undertest 3 according to the test information, and then reports the test result of the set frequency band of the set antenna to thecontrol device 1. For example, thewireless test apparatus 2 may measure the received power of the test information and calculate an average value as the wireless power when receiving the test information, and may calculate and obtain an Error Vector Magnitude (EVM) and a negotiation rate according to a management frame and a control frame included in the test information.

Thecontrol device 1 may determine whether the set antenna and the set frequency band pass the test according to the test result of the set frequency band of the set antenna reported by thewireless test device 2. For example, the test result of setting the frequency band of the antenna received by thecontrol device 1 includes the wireless power, the EVM, and the negotiation rate, and if it is determined that the wireless power is in the corresponding designated range, the EVM is smaller than the designated threshold, and the negotiation rate is greater than or equal to the rate threshold, it is determined that the set antenna and the set frequency band pass the test.

Thecontrol device 1 sends a fourth control instruction to thewireless testing device 2 to make thewireless testing device 2 work in the AP mode and configure thewireless testing device 2 with a unique corresponding SSID. Isolation of thewireless test device 2 in the open air domain is achieved by configuring thewireless test device 2 with a unique SSID such that the SSID of thewireless test device 2 in the open air domain is unique.

Thewireless test device 2 checks whether to establish a WIFI wireless communication connection with the set frequency band of the set antenna of the device undertest 3, and if the WIFI wireless communication connection is successfully established, returns information of successful connection to thecontrol device 1, and if the WIFI wireless communication connection cannot be established within a specified time, returns information of failed connection to thecontrol device 1.

If thecontrol device 1 receives the connection success information, it will send a third control instruction to the device undertest 3 to make the device undertest 3 send the test information to thewireless test device 2 by wireless communication. Thecontrol apparatus 1 may determine that the test for setting the antenna and setting the frequency band fails if the information of the connection failure is received. The test information may include management frames and control frames, etc., and complies with the ieee e802.11 protocol. The third control instruction is set according to actual needs, and the embodiment of the present invention is not limited.

After receiving the test information in the WIFI communication manner, thewireless test device 2 obtains a test result of the set frequency band of the set antenna of the device undertest 3 according to the test information, and then reports the test result of the set frequency band of the set antenna to thecontrol device 1.

And step two, sending a second control instruction. And the control device sends a second control instruction to the wireless test device so as to set the wireless test device to work in an STA mode and enable the wireless test device to access the set frequency band of the set antenna of the tested device.

And thirdly, receiving the first connection state. The wireless test device checks whether WIFI communication connection is established with the tested device, namely whether the wireless test device is accessed to a set frequency band of a set antenna of the tested device is detected, a first connection state is obtained, and then the first connection state is reported to the control device.

And ninthly, prompting that the tested device fails in the test. If the control device knows that the first connection state is connection failure, it indicates that the wireless test device and the device under test cannot establish WIFI communication connection in the current frequency band of the current antenna, and can prompt that the WIFI function test of the device under test fails. And if the control device judges that the currently set antenna and the set frequency band cannot pass the test according to the first test result, the control device can prompt that the WIFI function test of the tested device does not pass.

The following describes a process of the WIFI function test by taking a test process of the device under test in the STA mode and for one frequency band of one antenna of the device under test as an example, as shown in fig. 7, the specific process is as follows:

and step one, sending a fourth control instruction. And the control device sends a fourth control instruction to the wireless test device so that the wireless test device works in the AP mode and configures a unique corresponding SSID for the wireless test device.

And step two, sending a fifth control instruction. And the control device sends a fifth control instruction to the tested device so as to set the tested device to work in an STA mode and enable the tested device and the wireless test device to establish communication connection through setting a set frequency band of the antenna.

And thirdly, receiving a second connection state. The wireless testing device can check whether WIFI communication connection is established with the tested device or not, namely, whether the wireless testing device is accessed to a set frequency band of a set antenna of the tested device or not is detected, a second connection state is obtained, and then the second connection state is reported to the control device. The control device receives the second connection status. The wireless testing device establishes WIFI communication connection with the tested device, and the second connection state is successful; the wireless testing device and the tested device can not establish WIFI communication connection, and the second connection state is connection failure.

And fourthly, judging whether to establish connection. The control device judges whether WIFI communication connection is established between the wireless test device and the tested equipment or not according to the received second connection state, if the second connection state is connection failure, no WIFI communication connection is established, and the ninth step is carried out; and if the second connection state is successful, establishing WIFI communication connection, and entering the fifth step.

And step five, sending a sixth control instruction. And the control device sends a sixth control instruction to the tested device, and the tested device sends test information to the wireless test device after receiving the sixth control instruction.

And sixthly, receiving a second test result. And the wireless test device receives the test information from the tested equipment, obtains a second test result according to the test information, and reports the second test result to the control device.

And seventhly, judging whether the test is passed or not. And the control device receives the second test result and determines whether the currently set antenna and the set frequency band pass the test or not according to the second test result. If the test is judged to pass, entering the eighth step; and if the test is judged not to be passed, the ninth step is carried out. For example, the second test result includes wireless power and negotiation rate, and if the wireless power is in a corresponding designated range and the negotiation rate is greater than or equal to a rate threshold, the currently set antenna and the set frequency band pass the test; and if the wireless power is not in the corresponding specified range or the negotiated rate is smaller than the rate threshold, the currently set antenna and the set frequency band cannot pass the test.

And eighthly, determining that the current test is passed. After the control device determines that the currently set antenna and the set frequency band pass the test, the antenna or the frequency band can be replaced, and the test is continued.

And ninthly, prompting that the tested device fails in the test. If the control device knows that the second connection state is a connection failure, it indicates that the wireless test device and the device under test cannot establish a WIFI communication connection in the current frequency band of the current antenna, and can prompt that the WIFI function test of the device under test fails. And if the control device judges that the currently set antenna and the set frequency band cannot pass the test according to the second test result, the control device can prompt that the WIFI function test of the tested device does not pass.
