As shown in fig. 6, the present application provides a test apparatus 10, the test apparatus 10 comprising a first controller 101 and a first wireless communication module 102, the first controller 101 and the first wireless communication module 102 being connected, wherein:

the first wireless communication module 102 is configured to transmit a target communication signal between the first wireless communication module and at least one second wireless communication module of a target device to be tested, where the target communication signal is used to determine whether a first wireless communication connection between the first wireless communication module and the at least one second wireless communication module is a direct connection;

The first controller 101 is configured to transmit test-related data between the target device under test and the first wireless communication connection through the first wireless communication connection in a case where the first wireless communication connection is determined to be a direct connection.

The target communication signal is used to determine whether the first wireless communication connection between the first wireless communication module and the at least one second wireless communication module is a direct connection, and for example, the target communication signal may include a bidirectional ranging signal carrying a timestamp, that is, a ranging signal from a transmitting end to a receiving end and a ranging signal from a receiving end to a transmitting end, specifically, a time of flight may be calculated based on the timestamps carried by the bidirectional ranging signals, and a distance between the test device and the target device to be tested may be calculated based on the time of flight, and if the distance is less than a preset value, the first wireless communication connection between the first wireless communication module and the second wireless communication module is determined to be a direct connection, otherwise, the first wireless communication connection between the first wireless communication module and the second wireless communication module is determined not to be a direct connection.

It can be understood that in actual situations, the distance between the test equipment and the target equipment to be tested is often relatively close under the condition that the test equipment is used for testing the equipment to be tested, and the distance calculated based on the flight time can relatively accurately reflect the actual distance between the test equipment and the target equipment to be tested, so that under the condition that the distance is smaller than a preset value, the actual distance between the test equipment and the target equipment to be tested is relatively close, that is, the equipment to be tested is relatively more likely to be located within the effective test distance of the test equipment, and relay attack is relatively more likely not to occur; and under the condition that the distance is larger than or equal to the preset value, the true distance between the test equipment and the target equipment to be tested is longer, namely the equipment to be tested is more likely to be located outside the effective test distance of the test equipment, and relay attack is more likely to occur.

The first controller is configured to transmit, when it is determined that the first wireless communication connection is a direct connection, test related data between the first wireless communication connection and the target device to be tested, where the test related data may include at least one of a test request sent by the device to be tested to the test device, a test instruction sent by the test device to the device to be tested, response information returned by the device to be tested to the test instruction, and the like, for example, the test device sends, to the device to be tested, via the first wireless communication connection, a test instruction for indicating reading of state information of the device to be tested, and the device to be tested may send, based on the test instruction, state information of the device to be tested to the test device via the first wireless communication connection.

In addition, in the case that the first wireless communication connection is determined to be a direct connection, the first controller does not transmit test-related data between the target device to be tested through the first wireless communication connection.

The test equipment provided by the embodiment of the application comprises a first controller and a first wireless communication module, wherein the first controller is connected with the first wireless communication module, and the test equipment comprises the following components: the first wireless communication module is used for transmitting a target communication signal with at least one second wireless communication module of a target device to be tested, and the target communication signal is used for determining whether a first wireless communication connection between the first wireless communication module and the at least one second wireless communication module is a direct connection or not; the first controller is configured to transmit test related data between the first wireless communication connection and the target device to be tested through the first wireless communication connection under the condition that the first wireless communication connection is determined to be a direct connection, that is, in the present application, the test device tests the target device to be tested based on the first wireless communication connection only under the condition that the first wireless communication connection is determined to be a direct connection, so that relay attack can be effectively resisted, further, test safety can be improved, and in addition, the test device to be tested is tested through the first wireless communication connection between the test device and the device to be tested, and test operation convenience can be improved.

Optionally, the first wireless communication module is specifically configured to: receiving a first target communication signal sent by at least one second wireless communication module of the target device to be tested, and sending a second target communication signal to the at least one second wireless communication module of the target device to be tested; the first target communication signal carries a first time stamp, the second target communication signal carries a second time stamp, and the second controller of the target device to be tested is used for determining whether a first wireless communication connection between the first wireless communication module and the at least one second wireless communication module is a direct connection or not based on the first time stamp and the second time stamp;

or,

The first controller is further configured to determine whether a first wireless communication connection between the first wireless communication module and the at least one second wireless communication module is a direct connection based on the third timestamp and the fourth timestamp.

In an embodiment, it may be determined by the target device to be tested whether the first wireless communication connection is a direct connection. The first timestamp may include a timestamp of the target device to be tested sending the first target communication signal, and the second timestamp may include a timestamp of the test device receiving the first target communication signal and a timestamp of the test device sending the second target communication signal. In this way, the target device to be tested can calculate the flight time based on the timestamp of the first target communication signal sent by the target device to be tested, the timestamp of the first target communication signal received by the test device, the timestamp of the second target communication signal sent by the test device and the timestamp of the second target communication signal received by the target device to be tested, and if the flight time is smaller than the preset duration, the first wireless communication connection is determined to be a direct connection, otherwise, the first wireless communication connection is determined not to be a direct connection; or, the distance between the test device and the target device to be tested may be further calculated based on the time of flight, and in the case that the distance is smaller than a preset value, the first wireless communication connection is determined to be a direct connection, otherwise, the first wireless communication connection is determined not to be a direct connection. Because the distance calculated based on the flight time can more accurately reflect the real distance between the test equipment and the target equipment to be tested, whether the first wireless communication connection is a direct connection or not can be accurately identified based on the judgment mode.

In some alternative embodiments, the target device to be tested may feed back the determination result to the test device (i.e. the first wireless communication connection is a direct connection or not), so that the test device may determine whether to transmit the test instruction to the target device to be tested through the first wireless communication connection based on the determination result. Or, the target device to be tested may send a test request to the test device through the first wireless communication connection under the condition that the first wireless communication connection is determined to be a direct connection, so that the test device may send a test instruction to the target device to be tested through the first wireless communication connection in response to the test request.

The third timestamp may include a timestamp of the test device sending the third target communication signal, and the fourth timestamp may include a timestamp of the target device to be tested receiving the third target communication signal and a timestamp of the target device to be tested sending the fourth target communication signal. In this way, the test device may calculate a time of flight based on the time stamp of the test device sending the third target communication signal, the time stamp of the target device to be tested receiving the third target communication signal, the time stamp of the target device to be tested sending the fourth target communication signal, and the time stamp of the test device receiving the fourth target communication signal, and determine that the first wireless communication connection is a direct connection if the time of flight is less than a preset duration, or determine that the first wireless communication connection is not a direct connection if the time of flight is not less than the preset duration; or, the distance between the test device and the target device to be tested may be further calculated based on the time of flight, and in the case that the distance is smaller than a preset value, the first wireless communication connection is determined to be a direct connection, otherwise, the first wireless communication connection is determined not to be a direct connection. Because the distance calculated based on the flight time can more accurately reflect the real distance between the test equipment and the target equipment to be tested, whether the first wireless communication connection is a direct connection or not can be accurately identified based on the judgment mode.

Optionally, the first wireless communication module is specifically configured to: transmitting a target communication signal between the target device to be tested and at least one second wireless communication module of the target device to be tested before sending a test instruction to the target device to be tested each time, wherein the target communication signal is used for determining whether a first wireless communication connection between the first wireless communication module and the at least one second wireless communication module is a direct connection or not;

the first controller is specifically configured to: under the condition that the first wireless communication connection is determined to be direct connection at each time, respectively acquiring effective time corresponding to a test instruction to be sent currently, and transmitting test related data between the first wireless communication connection and the target device to be tested in the effective time, wherein the test related data comprises the test instruction.

In this embodiment, the valid time corresponding to each type of test instruction may be preset. The type of the test instruction may be set reasonably according to actual requirements, for example, may include a read instruction, a write instruction, and the like. The valid time is used for indicating the time for carrying out the safety communication based on the first wireless communication connection when the corresponding test instruction is executed, and for example, the valid time corresponding to each type of test instruction can be determined based on the statistical result of the time length required by the historical execution of the type of test instruction, so that the safety of the test can be improved while the execution of the test instruction is ensured.

Specifically, before each time a test instruction is sent to the target device to be tested, the test device may determine whether the first wireless communication connection is a direct connection, so as to ensure that the first wireless communication connection is a trusted communication connection, obtain an effective time corresponding to the test instruction to be executed when the first wireless communication connection is determined to be a direct connection, execute the test instruction based on the first wireless communication connection within the effective time, and stop executing the test instruction based on the first wireless communication connection when the effective time is exceeded, so that the security of the test may be further improved.

The first wireless communication module may detect, in real time, whether the device to be tested exists within a preset distance range of the test device, and if the first wireless communication module detects that only one device to be tested exists within the preset distance range of the test device, take the device to be tested as the target device to be tested; when the first wireless communication module detects that M devices to be tested exist in a preset distance range of the test device, the first controller may determine, from among the M devices to be tested, the target device to be tested based on target information of the M devices to be tested, for example, the first controller may use a device to be tested closest to the test device among the M devices to be tested as the target device to be tested, or may determine, according to identity information of the device to be tested, a test priority of the M devices to be tested, and use a device to be tested with the highest priority as the target device to be tested, or the first controller may control the display module to display target information of the M devices to be tested for a tester to check, and may determine, based on a selection input of the tester, the target device to be tested from among the M devices to be tested.

In some optional embodiments, the confirmation information may carry identity authentication information of the second wireless communication module, and the first wireless communication module may authenticate the identity authentication information of the second wireless communication module, and if the identity authentication passes, it indicates that the establishment of the first wireless communication connection between the first wireless communication module and the second wireless communication module is completed.

In the embodiment of the application, the first controller determines the target equipment to be tested from the M pieces of equipment to be tested according to the target information of the M pieces of equipment to be tested under the condition that the M pieces of equipment to be tested exist in the preset distance range of the testing equipment, so that the equipment to be tested needing to be tested with priority can be determined flexibly and reasonably under the condition that a plurality of pieces of equipment to be tested exist close to the testing equipment.

In another embodiment, at least one of identity information and status information of each of the M devices to be tested may be obtained through a first bluetooth module of the test device.
