It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.
Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts steps as a sequential process, many of the steps may be implemented in parallel, concurrently, or with other steps. Furthermore, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example 1
Fig. 1 is a flowchart of a method for testing a transponder according to an embodiment of the present application. The embodiment of the application can be suitable for the condition of verifying and testing the stability and the reliability of the transponder. The method may be performed by a transponder testing device, which may be implemented in software and/or hardware, and which is specifically configured in an electronic device, which may be a mobile terminal or a stationary terminal.
Referring to fig. 1, a method for testing a transponder according to an embodiment of the present application includes:
s110, acquiring a test strategy of a transponder to be tested; the testing strategy comprises sensitive environmental stress, an activation mode and an acceleration test time.
The transponder to be tested is the transponder to be tested.
When the transponder to be tested actually works, some environmental factors may exist, so that the transponder to be tested cannot work normally, for example, the environmental factors may be temperature, humidity, vibration and the like.
The activation mode refers to the activation frequency of the transponder to be tested being activated, the transponder to be tested is in a dormant state in normal times, and when the transponder to be tested is activated and started, the transponder to be tested enters a working state and transmits data to the outside. Wherein the activation mode belongs to sensitive working stress of the transponder to be tested.
The acceleration test refers to that under the premise of ensuring that the failure mechanism of the transponder to be tested is not changed, the transponder to be tested is accelerated to fail through strengthening test conditions so as to obtain necessary information in a short time, and the reliability of the transponder to be tested under normal conditions is evaluated. Wherein the time required for the acceleration test is the acceleration test time.
Optionally, the testing strategy of the to-be-tested transponder may be determined according to the type of the to-be-tested transponder, that is, different types of to-be-tested transponders may correspond to different testing strategies, for example, different sensitive environmental stresses of different types of to-be-tested transponders, different activation manners of different types of to-be-tested transponders, or different acceleration test times of different types of to-be-tested transponders may be used.
Optionally, the sensitive environmental stress includes a temperature cycling mode and/or a vibration mode.
In this embodiment, the actual situation may be combined, and according to the pre-analysis and the on-site use situation of the transponder to be tested, it is determined that the most sensitive main environmental factors of the transponder to be tested are temperature and vibration, and according to this, the temperature circulation mode of applying the temperature stress and the vibration mode of applying the vibration stress are determined.
Specifically, the sensitive environmental stress may include only the temperature-cycling mode, or the sensitive environmental stress may include only the vibration mode, or the sensitive environmental stress may include both the temperature-cycling mode and the vibration mode.
It will be appreciated that the selection test may be based on one sensitive environmental stress or two or more sensitive environmental stresses.
Typically, the sensitive environmental stresses include temperature cycling modes and vibration modes.
It can be appreciated that, considering that when the transponder to be tested actually works, a plurality of environmental factors are commonly present, the simultaneous test can be performed based on more than two kinds of sensitive environmental stresses, so that the test is more scientific and effective.
Alternatively, in order to determine the individual test results of the transponders to be tested for each sensitive environmental stress separately, it is also possible to test individually based on different sensitive environmental stresses separately.
In some embodiments, the sensitive environmental stress may also include humidity changes.
Alternatively, the warm-cycling mode may be determined according to the following: standard working condition information of the transponder to be tested is obtained; determining the temperature circulation mode according to the standard working condition information; the temperature cycling mode is applied to the transponder to be tested in a mode of periodically cycling a set temperature curve.
In this embodiment, standard working condition information of the transponder to be tested may be obtained by querying the product technical specification of the transponder to be tested.
Specifically, according to standard working condition information of the transponder to be tested, the working temperature condition of the transponder to be tested, such as average temperature condition, high temperature condition, low temperature condition, cooling rate, heating rate and the like, can be determined; and determining the temperature circulation mode of the transponder to be tested according to the working temperature condition of the transponder to be tested.
See a schematic diagram of a warm-cycling regime, as exemplified in fig. 2, wherein the temperature profile is set, i.e. one complete cycle in fig. 2. A complete cycle firstly carries out cooling from a high-temperature set value Tu according to a set cooling rate until the temperature is reduced to a low-temperature set value Tl; then, controlling the temperature to be kept unchanged at a low-temperature set value Tl in a first preset time period until the first preset time period is over; then, the temperature is raised from the low temperature set value Tl according to the set temperature raising rate until the temperature is raised to the high temperature set value Tu; and then the temperature is controlled to be kept at the high-temperature set value Tu within a second preset time period until the second preset time period is over.
Wherein, the set cooling rate and the set heating rate can be the same or different, for example, can be 8 ℃/min; the first preset time period and the second preset time period may be the same or different, such as may both be 25 minutes.
In the actual test, for convenience of implementation, the temperature cycle may be performed starting from the room temperature Tr.
In this embodiment, a continuous temperature cycle may be performed according to the set temperature profile exemplarily shown in fig. 2 throughout the transponder testing process.
It will be appreciated that the set temperature profile may take different forms based on different design requirements, and that the set temperature profile given by way of example in fig. 2 should not constitute the sole definition of the set temperature profile according to the application.
Alternatively, the vibration mode may be determined according to the following manner: standard working condition information of the transponder to be tested is obtained; and determining the vibration mode according to the standard working condition information.
Specifically, according to standard working condition information of the transponder to be tested, the working vibration condition of the transponder to be tested, such as vibration time, vibration force, vibration direction and the like, can be determined; and determining the vibration mode of the transponder to be tested according to the working vibration condition of the transponder to be tested.
Optionally, the vibration mode includes: respectively controlling the vibration of the transponder to be tested in each preset vibration direction; wherein the vibration processes of the preset vibration directions are not overlapped.
In this embodiment, for convenience of implementation, the preset vibration directions may be three directions of a horizontal axis, a vertical axis and a vertical axis, and the vibration of the transponder to be tested may be controlled in the three directions of the horizontal axis, the vertical axis and the vertical axis respectively, and the vibration time of each preset vibration direction may be the same or different, which may be specifically determined according to the actual situation.
Of course, for convenience of implementation, the vibration time of each preset vibration direction may be determined as the same vibration time, and the vibration time may be a fixed vibration time preset according to the vibration condition of the transponder to be tested.
For example, if the train speed is not less than 200 km/h, calculated as 500 m length of the whole train of long marshalling trains, then the time for the train to pass the transponder under test is not more than 9 seconds, and it can be approximately considered that the transponder under test is subjected to vibration for about 9 seconds during each activation. Taking line R as an example, a single-day train of line R is 41 columns, and the transponder to be tested is subjected to vibration for about 6 minutes in total in a cumulative way every day through calculation. Assuming an acceleration test time of 48 hours, the transponder to be tested has a vibration accumulation time of about 12 minutes.
It should be noted that, in the process of determining the sensitive environmental stress, the sensitive environmental stress cannot exceed the stress working limit of the transponder to be tested, so as to meet objective reality, and make the test scientific and effective.
In this embodiment, the acceleration test time may be determined according to the following manner: standard working condition information and site working condition information of the transponder to be tested are obtained; determining an acceleration factor based on a preset acceleration model according to the standard working condition information and the field working condition information; and determining the acceleration test time according to the acceleration factor, the average fault interval time, the failure times and the preset confidence level.
The field working condition information refers to the field working condition of the transponder to be tested, such as the temperature change condition, the activation condition and the like of the transponder to be tested in the actual field.
The average fault interval time is used for reflecting the time quality of the transponder to be tested, and the average fault interval time can embody one capability of the transponder to be tested for maintaining the function in the specified time.
The failure times refer to the failure times in the test process, and the preset confidence level refers to the confidence level of the failure times, for example, the test accepted failure times are 0, and the confidence level can be 90%.
In this embodiment, the average fault interval time may be predetermined according to the test requirement, for example, the average fault interval time may be selected to be 1 year for testing.
As shown in table 1 below, table 1 is one example of standard operating condition information and field operating condition information for a transponder. The field working condition information may include working condition information of a plurality of different sites.
Table 1:
in table 1, example data of field operation condition information and standard operation condition information are not limited to this embodiment, and specific field operation condition information and standard operation condition information may be determined according to actual situations.
Alternatively, different acceleration factors may be determined based on different preset acceleration models. For example, a warm-up acceleration factor may be determined based on a set warm-up acceleration model; and determining an activated acceleration factor based on the set activated acceleration model.
The temperature-cycling acceleration model comprises an inverse power law model, a cofin-Manson model, a deformation model thereof and the like, and can be used as a set temperature-cycling acceleration model by combining with an actual selection of a proper temperature-cycling acceleration model.
In this embodiment, a Norris-Landzberg modified Conffin-Manson model (a deformation model) may be selected as the set temperature-cycle acceleration model, so as to improve the calculation accuracy; the acceleration frequency belongs to an event compression test, and the activation acceleration factor is an event compression coefficient, so that an activation acceleration model, namely a ratio model, is set.
Specifically, the temperature and vibration field working stress level and the acceleration stress level can be respectively determined according to the field working condition information and the standard working condition information, and the acceleration factors of the stresses can be calculated according to the temperature and vibration field working stress level and the acceleration stress level.
For example, with continued reference to Table 1, the annual average minimum air temperature in City A and annual average maximum air temperature in City B may be used as the conditions for the on-site operation temperature change, with a temperature in the range of-15.6 to 28.7℃and an acceleration test in the range of-40 to 70 ℃. After the on-site and acceleration temperature ranges are determined, the on-site and acceleration temperature ranges can be substituted into a set temperature-cycle acceleration model, and a temperature-cycle acceleration factor is calculated.
For activating the acceleration factor, the acceleration factor and the field activation condition can be directly determined by adopting a ratio mode. For example, in the field operation of the transponder to be tested, the shortest 13 minutes of activation is performed once, namely 110 times/day, and in the acceleration test, the activation is performed once every 3 minutes, namely 480 times/day, so that the activation acceleration factor is calculated to be 4.36.
In this embodiment, the product life of the transponder to be tested is considered to obey the exponential distribution, so that the acceleration test time can be calculated according to an acceleration test time calculation formula of the exponential distribution product acceleration test, so as to improve the accuracy of the acceleration test time calculation.
It should be noted that, since the vibration magnitude is not accelerated in practice, only the temperature-cycling acceleration factor and the activation acceleration factor are considered in calculating the acceleration factor so as to meet the practice, so that the test is more scientific and effective.
And S120, controlling the comprehensive test box to provide a test environment for the transponder to be tested by adopting sensitive environmental stress in the acceleration test time, and controlling the transmission module to send an activation signal to the transponder to be tested by adopting an activation mode so as to enable the transponder to be tested to respond to the activation signal and output uplink information.
The activation signal may be a 27.095MHz radio frequency activation energy signal generated by the transmission module.
In this embodiment, the temperature and vibration test of the integrated stress test of the transponder to be tested is performed in an integrated test chamber. The comprehensive test box is a test box with comprehensive temperature and vibration functions, has the functions of rapid temperature change rate, providing comprehensive test environments for temperature, vibration and the like, namely, in the comprehensive test box, sensitive environmental stress can be applied to a transponder to be tested according to a temperature circulation mode and/or a vibration mode.
The transmission module, i.e. transponder transmission module (Balise Transmission Module, BTM), is adapted to receive uplink information of the transponder to be tested.
S130, determining a test result of the transponder to be tested according to the uplink information received in the acceleration test time.
Specifically, in the acceleration test process, the uplink information output by the transponder to be tested is multiple, the application can count the number of uplink information transmitted by the transponder to be tested, and the test result of the transponder to be tested is determined according to whether the received uplink information is correct or not.
For example, when the number of uplink information strips is wrong, it can be determined that the transponder to be tested fails the stability test; or when the uplink information is wrong, the transponder to be tested can be determined to not pass the stability test.
The embodiment of the application obtains the testing strategy of the transponder to be tested; the testing strategy comprises sensitive environmental stress, an activation mode and acceleration test time; in the acceleration test time, controlling the comprehensive test box to provide a test environment for the transponder to be tested by adopting sensitive environmental stress, and controlling the transmission module to send an activation signal to the transponder to be tested by adopting an activation mode so that the transponder to be tested responds to the activation signal and outputs uplink information; and determining the test result of the transponder to be tested according to the uplink information received in the acceleration test time. According to the technical scheme, on the basis that the failure mechanism of the transponder to be tested is unchanged, the life characteristics under the acceleration stress level are utilized to extrapolate or evaluate the life characteristics under the normal stress level, the reasonable-design acceleration test of the transponder to be tested is carried out by searching the physical-chemical relationship between the service life of the product and the stress, the working state of the transponder to be tested is monitored in real time in the test process, the performance of the transponder to be tested is tested and judged according to the test result, the stability and the reliability of the transponder are fully verified and tested, and the test accuracy is improved.
Example two
Fig. 3 is a flowchart of a method for testing a transponder according to a second embodiment of the present application, where the method is optimized based on the foregoing embodiment.
Further, the operation of determining the test result of the transponder to be tested according to the uplink information received in the acceleration test time is subdivided into analysis of each uplink information received in the acceleration test time to obtain a corresponding test message; and determining the test result according to each test message and the corresponding standard message so as to determine the determination process of the test result.
Wherein the same or corresponding terms as those of the above-described embodiments are not explained in detail herein.
Referring to fig. 3, the method for testing a transponder provided in this embodiment includes:
s210, acquiring a test strategy of a transponder to be tested; the testing strategy comprises sensitive environmental stress, an activation mode and an acceleration test time.
In this embodiment, the method for testing the transponder provided by the application can be controlled and executed by the upper computer system.
S220, controlling the comprehensive test box to provide a test environment for the transponder to be tested by adopting sensitive environmental stress in the acceleration test time, and controlling the transmission module to send an activation signal to the transponder to be tested by adopting an activation mode so that the transponder to be tested responds to the activation signal and outputs uplink information.
In the embodiment, a test mode of acceleration stress superposition is considered, and in acceleration test time, the comprehensive test box is controlled to be applied to the transponder to be tested in a temperature circulation mode, and meanwhile, the comprehensive test box is controlled to be applied to the transponder to be tested in a vibration mode; in the process of jointly superposing the temperature stress and the vibration stress, an activation signal is sent to the transponder to be tested in an activation mode, so that the transponder to be tested responds to the activation signal and outputs uplink information, and whether the transponder to be tested can normally work or not is determined under an acceleration environment.
In some embodiments, a single environmental stress test is also performed. Specifically, the comprehensive test box can be controlled to be applied to the transponder to be tested in the acceleration test time in a temperature circulation mode to provide a temperature test environment for the transponder to be tested, and meanwhile, the control transmission module is controlled to send an activation signal to the transponder to be tested in an activation mode to enable the transponder to be tested to respond to the activation signal and output uplink information, so that a first test result corresponding to temperature stress is obtained. And after the acceleration test time is over, the comprehensive test box is controlled to be applied to the transponder to be tested in a vibration mode, a vibration test environment is provided for the transponder to be tested, and meanwhile, the control transmission module is controlled to transmit an activation signal to the transponder to be tested in an activation mode, so that the transponder to be tested responds to the activation signal and outputs uplink information, and a first test result corresponding to the vibration stress is obtained. And combining the first test result and the second test result to obtain all uplink information.
In an alternative embodiment, before the test on the transponder to be tested is started in the acceleration test time, the transponder to be tested may be operated for a period of time, for example, 30 minutes, and after the transponder to be tested works stably, the acceleration stress test is performed on the transponder to be tested.
And S230, analyzing the uplink information received in the acceleration test time to obtain a corresponding test message.
In this embodiment, after the to-be-tested transponder responds to the activation signal, uplink information may be output to the transmission module, and then the transmission module sends the uplink information to the upper computer system, and the upper computer system analyzes each uplink information received in the acceleration test time to obtain the corresponding test message.
In this embodiment, there may be multiple test messages in the acceleration test time.
Optionally, the parsed test message may be visually displayed, for example, the message number, the message content, and the like may be displayed in a digital screen of the upper computer system.
S240, determining a test result according to each test message and the corresponding standard message.
The standard message refers to a correct message that the transponder to be tested needs to transmit to the outside. It should be understood that the standard messages correspond to the test messages.
Optionally, if the to-be-tested transponder belongs to a passive type to-be-tested transponder, the standard message is a default message preset in the to-be-tested transponder; and if the to-be-tested transponder belongs to the active type to-be-tested transponder, the standard message is a forwarding message correspondingly obtained from the ground electronic unit.
The default message is the message information which is unchanged by default, and for the passive type transponder to be tested, the passive type transponder to be tested can only transmit fixed message information to the outside.
In this embodiment, the ground electronic unit, i.e. the trackside electronic unit (Lineside Electronic Unit, LEU), is configured to provide variable message data to the active type transponder to be tested, and to provide an interface between the train control center device and the transponder to be tested. The LEU can receive the transponder message sent by the train control center equipment and continuously transmit the transponder message to the transponder to be tested, so that variable information can be sent to the outside such as train equipment; when the input channel fails or the LEU fails internally, the LEU sends a pre-stored setting message to the transponder to be tested, and the setting message can be failure information.
Therefore, for the active type transponder to be tested, the active type transponder to be tested can transmit variable message information to the outside, wherein the message information is a forwarding message obtained by the transponder to be tested from the ground electronic unit correspondingly.
Optionally, the determining the test result according to each test message and the corresponding standard message includes: each test message is respectively matched with a corresponding standard message, and the matching times are determined; and if the matching times are consistent with the test times, determining that the transponder to be tested passes the test.
The matching times are the times of successful matching of the test message and the corresponding standard message.
In this embodiment, if the matching times are inconsistent with the test times, it is determined that the transponder to be tested fails the test, that is, in the acceleration test process, the transponder to be tested has a working error, for example, the transponder to be tested has a message loss or a message transmission error, which indicates that the transponder to be tested cannot be in a normal working state all the time, and the transponder to be tested cannot work stably and reliably.
It can be appreciated that if the transponder to be tested cannot work stably and reliably, potential safety hazards may be brought to normal operation of the train.
In some embodiments, from the standpoint of practicality, a transponder to be tested may be randomly extracted from a batch of transponders for testing, without having to perform an accelerated stress test on each transponder in the batch, thereby improving testing efficiency.
In an alternative embodiment, at least two transponders to be tested can be randomly extracted from a batch of transponders to perform an acceleration stress test, so that the acceleration test time of a single transponder to be tested is reduced, and the test efficiency is improved.
For example, in an acceleration test simulating a 1 year operating period, if there are 4 transponders to be tested, the total acceleration test time is expected to be 312 hours, and the acceleration test time of a single transponder to be tested is 78 hours. For another example, in an acceleration test simulating a 2-year operating period, if there are 4 transponders to be tested, the total acceleration test time is expected to be 624 hours, and the acceleration test time of a single transponder to be tested is 156 hours.
On the basis of the embodiment, the embodiment of the application makes clear the determination process of the test result, analyzes the uplink information received in the acceleration test time to obtain the corresponding test message, and determines the test result according to the test message and the corresponding standard message. According to the technical scheme, on the basis that the failure mechanism of the transponder to be tested is unchanged, the life characteristics under the acceleration stress level are utilized to extrapolate or evaluate the life characteristics under the normal stress level, and the reasonable-design acceleration test of the transponder to be tested is carried out by searching the physical-chemical relationship between the life of the product and the stress, so that the working state of the transponder to be tested can be monitored in real time in the test process, the performance of the transponder to be tested is tested and judged, the stability and the reliability of the transponder are fully verified and tested, and the test accuracy is improved.
