Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
FIG. 1 is a schematic block diagram of a reliability testing system 100 for an in-vehicle smart antenna device 110 according to one embodiment of the present invention. Referring to fig. 1, a reliability test system 100 may include: a sleep wake-up Module 120, a vehicle mounted smart Antenna (TCAM) device 110, and a Personal Computer (PC) 130.
In this embodiment, the TCAM device 110 and the PC130 may be connected together via the hibernate wake-up module 120, that is, the hibernate wake-up module 120 is disposed between the TCAM device 110 and the PC 130. Specifically, the sleep wake-up module 120 may be connected to the TCAM device 110 and the PC130 via USB lines, respectively.
The sleep wake module 120 may be configured to periodically power down and up to wake up the TCAM device 110 in a timed sleep. Here, the power-down and power-up cycles may be performed according to a preset period. The preset period is the sum of a first preset time for continuously powering on and a second preset time for continuously powering off in each cycle period. The first predetermined period of time is preferably slightly greater than the second predetermined period of time. Specifically, the first preset time period may be set to be 3 minutes and the second preset time period may be set to be 30 seconds, for example, the TCAM device 110 and the PC130 are disconnected for 30 seconds and connected for 3 minutes, and the cycle is continued according to the period.
From a testing perspective, the TCAM device 110 may be the master device 110 or the slave device 110. In the process of performing the reliability test on the TCAM device 110, the reliability test may be performed on the master device 110 or the slave device 110, and a synchronous reliability test may be performed on the master device 110 and the slave device 110.
Various network modules may be integrated within the TCAM device 110. For example, the WIFI module 111, the 5G communication module 112, and/or the vehicle ethernet (PHY) module 113, and the like. Illustratively, when the WIFI modules 111, 5G communication module 112 and PHY module 113 are integrated in both the master device 110 and the slave device 110, the WIFI module 111 of the master device 110 and the WIFI module 111 of the slave device 110 may be connected through a 2.4G/5G WIFI link. The 5G communication module 112 of the master device 110 and the 5G communication module 112 of the slave device 110 may be connected to the 5G base station 200 through 5G communication links, respectively. The PHY module 113 of the master device 110 and the PHY module 113 of the slave device 110 may be connected by a physical twisted pair.
In addition, when the master device 110 and the slave device 110 are subjected to the master-slave synchronization reliability test, the master device 110 and the slave device 110 may be respectively connected in series to the PC130 through the sleep-wake module 120 through the USB cable. After the test is started, the PC130, the master device 110 and the slave device 110 are all configured to be powered on for a long time, the sleep wakeup module 120 is configured to be powered off and powered on periodically to disconnect and connect the USB of the master device 110 and the USB of the slave device 110 at regular time, so that the master device 110 and the slave device 110 are waken up after being in short sleep, after the master device 110 and the slave device 110 are waken up at the same time, the clocks are synchronized again, the 5G network is on the network again, and the drive of the WIFI and the PHY is loaded again, so that the automatic experiment foundation in a new round is not coupled with the test environment in the previous round, and the stability of the test process and the accuracy of the test result are improved.
To facilitate controlling the timed sleep and wake-up of the TCAM device 110, in some embodiments, the sleep wake-up module 120 may be configured as a relay. The relay is preferably a programmable relay. The programmable relay can conveniently control the dormancy awakening of the TCAM equipment 110, thereby simplifying the control logic and improving the control efficiency.
Further, the TCAM device 110 may include a controller. The controller may be used to perform the reliability testing method for the in-vehicle smart antenna apparatus 110 of any one or a combination of the embodiments described below.
Fig. 2 is a schematic flow chart of a reliability testing method for the vehicle-mounted smart antenna device 110 according to one embodiment of the present invention. The reliability test method of this embodiment can be applied to the reliability test system 100 in the foregoing embodiments. Referring to fig. 2, the reliability test method may include steps S202 to S208.
Step S202, after the TCAM device 110, the sleep wake-up module 120, and the PC130 are powered on, the reliability test script is started to run through the TCAM device 110, so as to execute a reliability test check item on the TCAM device 110.
Step S204, after the power is continuously turned on for the first preset time, the sleep wakeup module 120 is powered off to control the TCAM device 110 to be disconnected from the PC130, so that the TCAM device 110 enters a sleep state.
Step S206, after the power is continuously turned off for the second preset time, the sleep wakeup module 120 is powered on to control the TCAM device 110 and the PC130 to enter the connection state, so that the TCAM device 110 is woken up.
Step S208, taking the sum of the first preset duration and the second preset duration as a cycle period, periodically powering down and powering up the sleep/wake-up module 120 to periodically sleep and wake up the TCAM device 110. When the TCAM device 110 enters the sleep state each time, the reliability test check items are all reset to the initial state by the reliability test script, and the reliability test script starts to run again after the TCAM device 110 is awakened each time.
According to the embodiment of the invention, the TCAM device 110 is awakened through periodical power-off and power-on of the dormancy awakening module 120, so that an automatic test traversal cycle experiment is performed on the TCAM device 110, and the purpose of verifying the reliability of software and hardware functions of the TCAM device 110 is achieved. Moreover, after the TCAM device 110 is dormant each time, the reliability test items are all reset to the initial state by the reliability test script, and after the TCAM device 110 is awakened each time, the reliability test script starts to run again to re-execute the reliability test items, so that the new round of automated experiment foundation is not coupled with the previous round of test environment, and the stability of the test process and the accuracy of the test result are improved.
In some embodiments, the reliability test check items may include any one or more of data traffic dialing, network time synchronization, network mode checking, data traffic PING checking, WIFI service settings, PHY traffic PING checking, and the like.
In each cycle, when the TCAM device 110 enters the sleep state, the sleep wakeup flag bit may be printed in a kernel log of the TCAM device 110, and then after the TCAM device 110 is awakened, the printed sleep wakeup flag bit is obtained from the kernel log through the reliability test script, so as to check whether the sleep wakeup flag bit is recorded in a sleep wakeup flag bit configuration file of the TCAM device 110. If the sleep wakeup flag bit configuration file does not record the sleep wakeup flag bit, whether the TCAM device 110 is the master device 110 or the slave device 110 is determined based on the SD card path of the TCAM device 110, and if the TCAM device 110 is the master device 110, the master device 110 is controlled to run a master device logic so as to execute a reliability test check item on the master device 110, and after the execution is completed, the sleep wakeup flag bit is written into the sleep wakeup flag bit configuration file. If the TCAM device 110 is a slave device 110, the slave device 110 is controlled to run a slave device logic so as to execute a reliability test check item on the slave device 110, and after the execution is completed, write the sleep wakeup flag bit into the sleep wakeup flag bit configuration file. By adopting the embodiment, whether the current awakened TCAM device 110 is the master device 110 or the slave device 110 can be determined, and then the master device logic is executed on the master device 110, and the slave device logic is executed on the slave device 110, so that the pertinence of the reliability test is effectively improved, and the test error is avoided from affecting the accuracy of the test result.
Further, in a plurality of cycle periods, each time the TCAM device 110 enters the sleep state, a sleep wakeup flag bit may be printed in the kernel log of the TCAM device 110. That is to say, after the TCAM device 110 is awakened, when the TCAM device 110 is awakened next time, a new dormancy wakeup flag bit is printed in the kernel log, so that after the TCAM device 110 is awakened next time, the new dormancy wakeup flag bit will not appear in the dormancy wakeup flag bit configuration file necessarily, and the TCAM device 110 starts to execute the reliability check item again, so that the automatic cycle test on the TCAM device 110 can be implemented.
It should be noted that, when the master device 110 and the slave device 110 are both connected to the PC130, the master device 110 and the slave device 110 are simultaneously woken up to start running the same set of reliability test scripts.
In some embodiments, when determining whether TCAM device 110 is master device 110 or slave device 110 based on the SD card path of TCAM device 110, the reliability test script may make a binary determination with the slave device flag bit file or the master device flag bit file under the SD path of TCAM device 110. When the binary judgment is performed by using the slave device zone bit file, the reliability test script may check whether the slave device zone bit file exists in the SD card path of the TCAM device 110, and if the slave device zone bit file does not exist in the SD card path, the TCAM device 110 may be judged as the master device 110. On the contrary, if the slave device flag bit file exists in the SD card path, the TCAM device 110 may be determined to be the slave device 110.
In some further embodiments, when controlling the master device 110 to run the master device logic, the test program may be first called by the reliability test script, and during the running of the test program, the following reliability test check items are performed on the master device 110:
and carrying out data service dialing. In the process of dialing the data service, it may be checked whether the primary device 110 has registered the 5G network, and if the 5G network has been registered, the data service dialing may be directly performed, and the next action is performed after the data service dialing. If the 5G network is not registered, the master device 110 may cyclically check whether the 5G network is registered or not with a third preset time as a period, and perform the next action after the number of times of the cyclic check reaches the first preset number, that is, perform the next action regardless of whether the 5G network is registered or not after the number of times of the cyclic check reaches the second preset number. Therefore, the test can be ensured to continue to be carried out downwards, and the test stop caused by the abnormity is avoided. The third preset time and the first preset times can be preset according to the actual application requirements. For example, the third preset time period may be set to 0.5 seconds, and the first preset number may be set to 60 times.
And carrying out network time synchronization. During the network time synchronization, it may be checked whether the data service of the master device 110 is available, and if the data service is available, the network time synchronization is directly performed, and the next action is performed after the synchronization. Otherwise, if the data service is unavailable, the data service of the master device 110 is checked cyclically with the fourth preset duration as a period, and the next action is performed after the number of times of the cyclic check reaches the second preset number, that is, the next action is performed regardless of whether the data service is available or not after the number of times of the cyclic check reaches the second preset number. Therefore, the test can be continuously carried out downwards, the test abnormity caused by the abnormity of the data service is avoided, and the stability of the test and the accuracy of the test result are improved. The fourth preset time and the second preset times can be preset according to the actual application requirements. For example, the fourth preset time period may be set to 0.5 seconds, and the second preset number may be set to 60 times.
And performing network mode check, and recording a corresponding first test result to a first log file after adding a time stamp to the first test result. Specifically, the network mode registered by the current device can be acquired through a network interface (network interface), and is recorded to the first log file after being time-stamped.
And performing PING check on the data service, adding a time stamp to the corresponding second test result, and recording the result to a second log file. Specifically, the PING result is obtained through a PING external network address (such as 8.8.8.8), time stamped and recorded in a second log file.
And starting and setting the WIFI hotspot, adding a timestamp to a corresponding third test result, and recording the third test result to a third log file.
And (5) carrying out PHY service PING check, adding a time stamp to a corresponding fourth test result, and recording the result to a fourth log file. Specifically, the PING net result is obtained from the device 110PHY address (e.g., 198.18.32.16) via PING and time-stamped and recorded to the fourth log file.
In addition, when the above reliability test check items are performed, the first log file, the second log file, the third log file, and the fourth log file may all be stored in the SD path of the master device 110. After the reliability testing stage is performed or the reliability testing stage is completed as a whole, the first log file, the second log file, the third log file and the fourth log file stored in the master device 110SD may be checked, and further, the specific execution result of each service in each time period of the testing process may be confirmed by the timestamp and the service execution result.
In addition, for convenience of storage and subsequent check, each log file may be named using a designated character, for example, as a first log file name, a second log file name, a third log file name, and a fourth log file name, the first log file name, the second log file name, the third log file name, and the fourth log file name, the second log file name, the third log file name, and the fourth log file name, the third log file name, and the fourth log file name.
