Background technique

Usually, before equipment leaves the factory or is mass-produced, it is necessary to inspect the performance of the equipment, including reliability tests, to test the reliability of the equipment. A common implementation method for equipment reliability tests is to use third-party supervision, which means that during the reliability supervision test of the verified equipment, a third party sends a dedicated person to the equipment reliability test site to supervise the entire process of the reliability test of the verified equipment. This ensures the correctness and rationality of the equipment operation, testing, maintenance and other work during the equipment reliability test, and guarantees the accuracy of the reliability verification results.

In one embodiment, as shown in Figure 1, the present application provides a reliability testing equipment, including a testing device 102, a monitoring device 104 and a data processing device 106, the testing device 102 is connected to the verified device 100 and the data processing device 106, the monitoring device 104 is connected to the data processing device 106, and is arranged on the verified device 100.

The verified device 100 is a device that needs to undergo a reliability test. The reliability test is used to record, analyze and verify the reliability of the device, so as to adjust the design or process of the device, or to analyze whether the parameters of the device meet the requirements, such as the average failure interval, expected service life, expected scrap age or working stability of the device. Therefore, the device undergoing the reliability test is referred to as the verified device 100, and the type or specification of the verified device 100 is not limited in this application.

Specifically, the test device 102 is used to collect the reliability data of the verified device 100 and transmit it to the data processing device 106. The test device 102 is connected to the verified device 100, directly obtains the reliability data of the verified device 100, such as the working voltage, working frequency, etc., and then transmits the reliability data to the data processing device 106. According to the type and function of the verified device 100, the test device 102 can obtain different reliability data, and the reliability data can include the working parameters of the verified device 100, and can also include parameters such as the rated parameters of the verified device 100. In order to collect the reliability data of the verified device 100, the test device 102 will also use different devices according to the type and function of the verified device. That is, the test device 102 is determined according to the verified device 100. For example, when the verified device 100 is an electrical device, when it is necessary to test the electrical signal in the reliability test, the test device 102 can be an electric field sensor or an oscilloscope or other devices that can collect electrical signals. When the verified device 100 is a force transmission device and the magnitude of the force needs to be tested in a reliability test, the testing device 102 may be a pressure transmitter or the like.

Furthermore, the test device 102 may include a test chip in addition to the test instrument (such as an electric field sensor or a pressure transmitter). The test chip stores a pre-edited program that can adjust the collection of reliability data according to the test requirements. For example, the program running in the test chip can control the collection frequency of the reliability data by the test instrument, or control the test instrument to obtain reliability data at a set time. Further, the test device 102 may also include a test companion device for assisting the test instrument or the test chip, such as a power supply, a signal generator, and a standard sample.

The monitoring device 104 is used to monitor the reliability test process of the verified device 100, and send the generated monitoring data to the data processing device 106. The monitoring device 104 is set on the verified device 100, and can be set in a position near the verified device 100, or the verified device 100 can be placed in a reserved position set by the monitoring device 104. Depending on the different monitoring devices 104, there can be different settings, as long as the monitoring device 104 can monitor the reliability test process of the verified device 100. Exemplarily, when the monitoring device 104 is a camera, the verified device 100 is set in the shooting range of the camera. When the monitoring device 104 is an experimental monitoring table, the verified device 100 can be placed on the table of the experimental monitoring table. The monitoring device 104 generates monitoring data by monitoring the reliability test process of the verified device 100. The monitoring data includes the interaction record between the verified device 100 and the external environment, which is convenient for analyzing whether the verified device 100 is affected by the external environment during the reliability test.

In fact, the reliability test of the verified device 100 needs to last for a long time, and during this long verification process, unforeseen accidents may occur, such as human error, unexpected power failure, loose components or illegal operation, etc. These accidents will affect the reliability data of the verified device 100, resulting in large errors in the reliability verification results obtained when analyzing the verified device 100. In order to ensure the accuracy of the reliability verification results, a monitoring device 104 is set to monitor the reliability test process of the verified device 100, and the monitoring data obtained by monitoring is sent to the data processing device 106.

Furthermore, the monitoring device 104 may be an audio and video acquisition device, such as a camera, which can record the reliability test process of the verified device 100. It should be noted that the test device 102 may also be an audio and video acquisition device, but when the test device 102 uses an audio and video acquisition device, the audio and video acquisition device is used to acquire the working parameters or related functional performance of the verified device 100. For example, the verified device 100 may be photographed at regular intervals to obtain the readings of the verified device 100 in the form of images, and then converted into the working parameters of the verified device 100 through image processing. The audio and video acquisition device of the monitoring device 104 is used to record the environment of the verified device 100 or whether the verification process is abnormal, and is usually unrelated to the working parameters or performance of the verified device 100.

The data processing device 106 receives the reliability data sent by the test device 102 and the monitoring data sent by the monitoring device 104, and analyzes the reliability data and the monitoring data to obtain the reliability verification result of the verified device 100. Exemplarily, the data processing device 106 can be a computer terminal connected to the test device 102 and the monitoring device 104, wherein the connection mode can be a wired connection or a wireless connection.

In this embodiment, the reliability test equipment includes a test device 102, a monitoring device 104 and a data processing device 106. The test device 102 is connected to the verified device 100 and the data processing device 106. The monitoring device 104 is connected to the data processing device 106 and is set on the verified device 100. The test device 102 is used to collect the reliability data of the verified device 100 and transmit it to the data processing device 106. The monitoring device 104 is used to monitor the reliability test process of the verified device 100 and send the generated monitoring data to the data processing device 106. The data processing device 106 obtains the reliability verification result of the verified device 100 according to the reliability data and the monitoring data. By setting the test device 102 to obtain the reliability data of the verified device 100 during the reliability test, and setting the monitoring device 104 to monitor the reliability test process of the verified device 100, there is no need to set up manual supervision, which can improve the convenience of the reliability test. At the same time, the double verification of the verified device 100 is realized through the reliability data and the monitoring data, and the reliability verification result is also guaranteed to have sufficient accuracy.

In one embodiment, as shown in FIG. 2 , the data processing device 106 includes an edge computing unit 202 and a data analysis unit 204 , the edge computing unit 202 is connected to the monitoring device 104 and the data analysis unit 204 , and the data analysis unit 204 is connected to the testing device 102 .

Since the monitoring device 104 needs to monitor the reliability test process, as the reliability test progresses, the monitoring data may reach GB or even TB level. If the monitoring data is transmitted over long distances, it will consume more resources and will be affected by factors such as network bandwidth. It is easy to make errors, which will reduce the accuracy of the reliability verification results and make the convenience insufficient.

Specifically, in this embodiment, an edge computing unit 202 connected to the monitoring device 104 is provided. The edge computing unit 202 receives monitoring data and can perform operations on the monitoring data locally without transmitting the monitoring data over long distances. And when there are multiple monitoring devices 104, multiple monitoring devices 104 can be connected to the edge computing unit 202, and the edge computing unit 202 analyzes the reliability test process of the verified device 100 according to the monitoring data to obtain an environmental reliability analysis result. Furthermore, the edge computing unit 202 can use artificial intelligence algorithms and machine vision algorithms to analyze the monitoring data, judge and record whether there are any illegal operations or unexpected situations during the reliability test, and obtain an environmental reliability analysis result.

The data analysis unit 204 receives the reliability data and the environmental reliability analysis result, and obtains the reliability verification result according to the reliability data and the environmental reliability analysis result. The data analysis unit 204 receives the reliability data, analyzes the working parameters or functional performance of the verified device 100 according to the reliability data, and then obtains the reliability verification result by comprehensive analysis in combination with the environmental reliability analysis result.

Furthermore, in another embodiment, the edge computing unit 202 can also be connected to the test device 102 to obtain the reliability data collected by the test device 102. On the basis of obtaining the environmental reliability analysis results, the edge computing unit 202 can also perform preliminary processing on the reliability of the verified device 100 according to the reliability data, and then transmit the processed data to the data analysis unit 204. For example, the edge computing unit 202 marks the time period in which unexpected situations or illegal operations occur in the environmental reliability analysis results, and then removes the data of the corresponding time period in the reliability data, thereby obtaining processed reliability data, and transmits the processed reliability data to the data analysis unit 204.

The way in which the data analysis unit 204 combines the reliability data and the environmental reliability analysis results for analysis is not unique. In one embodiment, the data analysis unit 204 also obtains the device reliability analysis results based on the design parameters and reliability data of the verified device 100. The data analysis unit 204 stores the design parameters of the verified device 100, which represent the working parameters of the verified device 100 when working under ideal conditions, or the performance requirements that the verified device 100 is given to achieve when it is designed. The data analysis unit 204 determines the reliability data based on the design parameters of the verified device 100 to obtain the device reliability analysis results. For example, it determines whether the verified device 100 meets the design parameters in various dimensions, that is, whether the verified device 100 meets the performance requirements.

After obtaining the device reliability analysis result, the data analysis unit 204 adjusts the device reliability analysis result according to the environmental reliability analysis result to obtain the reliability verification result of the verified device 100. The data analysis unit 204 may re-analyze the data of the corresponding time period in the device reliability analysis result according to the time period when the unexpected situation or illegal operation occurs in the environmental reliability analysis result, or delete the data of the time period, and adjust the device reliability analysis results of the adjacent time periods to ensure the accuracy of the obtained reliability verification result.

In this embodiment, by setting up the edge computing unit 202 and the data analysis unit 204 to calculate the data separately, on the one hand, the load of data transmission is reduced, and on the other hand, by separately calculating the equipment reliability analysis results and the environmental reliability analysis results, and then obtaining the reliability verification results, the accuracy of the reliability verification results is improved.

In one embodiment, as shown in FIG. 2 , the data processing device 106 further includes a data transmission unit 206 , which connects the data analysis unit 204 , the edge computing unit 202 , and the testing device 102 .

Specifically, the data analysis unit 204 may not be set up at the reliability test site, and it can be connected to the edge computing unit 202 by wireless transmission or by wired transmission. In order to ensure the stability and accuracy of the transmission process, a data transmission unit 206 may be provided, which connects the data analysis unit 204, the edge computing unit 202 and the test device 102, and can receive the reliability data sent by the test device 102 and the environmental reliability analysis results sent by the edge computing unit 202, and send the reliability data and the environmental reliability analysis results to the data analysis unit 204. Optionally, the data transmission unit 206 can simultaneously receive the reliability data sent by multiple test devices 102 and the environmental reliability analysis results sent by multiple edge computing units 202.

In this embodiment, by providing a data transmission unit 206 between the data analysis unit 204 and the edge computing unit 202 for data transmission, the stability and accuracy of the data transmission process can be guaranteed, and the applicability of the reliability test equipment can be improved.

In one embodiment, as shown in FIG. 3 , the reliability test equipment further includes a storage device 108 , and the storage device 108 is connected to the test device 102 and the monitoring device 104 .

Specifically, in order to enable the staff to call the reliability data and monitoring data when conducting data review or inspection, a storage device 108 connected to the test device 102 and the monitoring device 104 is also provided to store the reliability data and monitoring data, and the staff can call them according to the needs. Exemplarily, the storage device 108 can be a memory card.

In this embodiment, by setting up a storage device 108 to save the reliability data collected by the testing device 102 and the monitoring data of the monitoring device 104, it is equivalent to saving the original data of the reliability test, which is convenient for the staff to check the reliability test process and improve the applicability of the reliability test equipment.

Based on the same technical concept, the present application also provides a reliability testing method. The reliability testing method provided in the embodiments of the present application can be applied to the reliability testing equipment recorded in the above embodiments. Specifically, in an exemplary embodiment, as shown in Figure 4, a reliability testing method is provided, and the method is applied to the data processing device 106 in the reliability testing device as an example for explanation, including the following steps 402 to 404.

Step 402, obtaining reliability data and monitoring data of the verified device.

Among them, the reliability data is collected by the test device, which is connected to the verified device, collects the reliability data of the verified device and transmits it to the data processing device. The monitoring data is obtained by the monitoring device monitoring the reliability test process of the verified device. The monitoring device is set in the verified device, generates monitoring data and sends it to the data processing device. Specifically, the data processing device obtains the reliability data through the test device and obtains the monitoring data through the monitoring device. The relevant content has been recorded in the above embodiments and will not be repeated here.

Step 404, obtaining the reliability verification result of the verified device according to the reliability data and the monitoring data.

Specifically, the data processing device analyzes the reliability data and the monitoring data to obtain the reliability verification result of the verified device. In one embodiment, as shown in FIG5 , step 404 includes steps 502 to 506 .

Step 502: Obtain environmental reliability analysis results based on monitoring data.

The data processing device can use artificial intelligence algorithms and machine vision algorithms to analyze the monitoring data, determine and record whether there are any illegal operations or unexpected situations during the reliability test, and obtain environmental reliability analysis results.

Step 504: Obtain equipment reliability analysis results based on the design parameters and reliability data of the equipment to be verified.

The design parameters are preset performance parameters of the verified device, which represent the working parameters of the verified device when it works under ideal conditions, or the performance requirements that the verified device is given to achieve during design.

Specifically, the data processing device also receives reliability data, analyzes the working parameters or functional performance of the verified device according to the reliability data, determines the reliability data according to the design parameters of the verified device, and obtains the device reliability analysis result.

Step 506: Adjust the equipment reliability analysis result according to the environmental reliability analysis result to obtain the reliability verification result of the verified equipment.

The equipment reliability analysis results are combined with the environmental reliability analysis results to obtain the reliability verification results through comprehensive analysis. For example, the data of the corresponding time period in the equipment reliability analysis results can be re-analyzed according to the time period when unexpected situations or illegal operations occur in the environmental reliability analysis results, or the data of the time period can be deleted and the equipment reliability analysis results of the adjacent time periods can be adjusted to ensure the accuracy of the obtained reliability verification results.

In one embodiment, step 504 includes steps 602 to 604 .

Step 602: Obtain test performance parameters of the device to be verified based on the reliability data.

The test performance parameter may be a working parameter of a certain aspect of the verified device. For example, if the verified device is a gas analyzer, the test performance parameter may be detection limit, indication error, repeatability, etc. Specifically, the data processing device can analyze based on the reliability data to obtain the test performance parameters such as detection limit, indication error, repeatability, etc.

Step 604, obtaining equipment reliability analysis results based on the design parameters and test performance parameters of the equipment to be verified.

Specifically, the data processing device compares and analyzes the corresponding test performance parameters based on the stored design parameters, that is, compares the test performance parameters with the corresponding design parameters, and obtains the equipment reliability analysis results based on the comparison results.

In one embodiment, step 604 includes steps 702 to 704 .

Step 702: Obtain a design parameter range according to the design parameters of the device to be verified and a preset deviation allowable value.

Specifically, the data processing device obtains the design parameter range for the design parameters of the verified device according to the preset deviation allowable value. Different design parameters may have different preset deviation allowable values, and correspondingly obtain different design parameter ranges. The preset deviation allowable value may be set by the staff, and the value of the value is related to the accuracy of the verified device.

Step 704, comparing the design parameter range with the test performance parameter to obtain equipment reliability analysis results.

Specifically, the data processing device compares the test performance parameter with the corresponding design parameter range. When the test performance parameter is within the design parameter range, it can be analyzed that the verified device meets the performance requirements in this performance aspect, and the verified device has not failed or failed. When the test performance parameter is not within the design parameter range, it can be analyzed that the verified device does not meet the performance requirements in this performance aspect, and the verified device is in a faulty or failed state.

In this embodiment, by comparing the reliability data with the design parameters and obtaining the equipment reliability analysis results, it is possible to accurately determine whether the performance of the verified equipment meets the requirements, analyze the reliability of the equipment, and improve the accuracy of the equipment reliability analysis results.

In order to better understand the above solution, in combination with the application scenario shown in FIG3 , a detailed explanation is given below in combination with a specific embodiment.

In one embodiment, the verified device is a gas analyzer of a certain model. In this embodiment, a reliability test is carried out on the gas analyzer to mainly verify whether its average failure interval meets the reliability index of not less than 1000 hours. According to the reliability test plan, a cumulative reliability test of 1204 hours is required, and no responsible failure is allowed to occur during the test.

Test device: The target gas analyzer needs to test and collect the performance indicators of the target gas analyzer every 4 hours during the reliability test. During the reliability test, standard gas and automatic sampler are used to complete sample injection and testing, and the test data of the target gas analyzer is output. At the same time, the test data of the target gas analyzer is output to the local storage server (storage device) through the data bus for storage, and is also output to the remote transmission module (data transmission unit) through the data bus.

The monitoring device uses a high-definition camera to monitor and record the reliability test process of the target gas analyzer. It can collect audio and video data of the target gas analyzer during operation, testing, maintenance, etc. in the reliability test, and output it to the local storage server (storage device) through the data bus for storage, and transmit it to the local edge computing unit through the data bus.

The edge computing unit uses artificial intelligence algorithms and machine vision algorithms to analyze whether the target gas analyzer is in normal working condition based on the audio and video data of the operation, testing, maintenance and other processes collected by the monitoring device during the reliability test of the target gas analyzer, and determines whether a fault or abnormality (such as shutdown, foreign object intrusion, etc.) has occurred, etc., and outputs the analysis results (environmental reliability analysis results) to the remote transmission module (data transmission unit) through the data bus.

The data transmission unit transmits the test data of the target gas analysis instrument performance indicators obtained by the test device and the target gas analysis instrument status analysis results obtained by the edge computing unit to a remote data analysis unit through the network, and the data analysis unit can be a host computer.

The data analysis unit obtains the test data of the target gas analyzer performance indicators input by the data transmission unit through data analysis, and obtains the test results of its detection limit, indication error, repeatability and other performance indicators (test performance parameters), and compares them with the preset performance indicator tolerance range (design parameter range), so as to determine whether the target analyzer is in normal working condition. The judgment result (equipment reliability analysis result) is compared with the analysis result (environmental reliability analysis result) obtained by the edge computing unit, and the status of the target gas analyzer is confirmed for the second time, and the test time of normal working condition is included in the cumulative effective working time. The cumulative effective working time and the number of responsible failures of the target gas analyzer during the reliability test are counted, and the reliability test of whether it has passed the mean failure interval time of not less than 1000 hours is analyzed and determined to obtain the reliability verification result.
