Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The electronic controller working condition coupling test method based on the offshore atmospheric environment laboratory can be applied to an application environment shown in fig. 1. The upper computer 3 communicates with the electronic controller 2 and the electronic controller 4 through a network. Both electronic controllers 2, 4 may be powered by a regulated power supply 5, wherein the electronic controller 2 under test is arranged in the experimental setup 1. After receiving the adaptability test instruction, the upper computer 3 can determine a test rule based on the environmental information of the offshore area, configure a normal environment and a test environment for the experimental equipment, and obtain a working condition coupling test result of the electronic controller 2 by performing multiple tests on the electronic controller 2 under multiple environments, wherein the electronic controller 4 can be used as a control group for testing under the normal environment. The upper computer 3 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and the like.
In one embodiment, as shown in fig. 2, an electronic controller working condition coupling test method based on an offshore atmospheric environment laboratory is provided, and the method is applied to the upper computer in fig. 1 for illustration, and includes the following steps:
step S202, in response to an adaptability test instruction of the electronic controller to be tested in the offshore area, determining a vibration test rule, a damp-heat test rule and a salt spray test rule according to the environmental information of the offshore area.
The electronic controller is an important electronic product element, is a miniature computer management center, takes signal acquisition, calculation processing, analysis judgment and decision countermeasures as input, and then takes control instructions and command executors as output. The electronic controller to be tested may be an electronic controller provided in an offshore area, for example, an electronic controller provided in a south sea area. Because no test scheme for the electronic controller of the atmospheric environment of the south China sea exists at present, the upper computer can be pre-configured with various test rules for testing the performance of the electronic controller of the atmospheric environment of the south China sea, so that the atmospheric environment of the south China sea is simulated.
The host computer may first select the appropriate test object, including selecting based on the specification and number. The upper computer can select an electronic controller to be tested which meets the requirements from a plurality of electronic controllers. For example, in one embodiment, the host computer may obtain device specifications for a plurality of candidate electronic controllers. The equipment specifications comprise equipment-level specifications, material-level specifications and the like, and the upper computer can take the equipment specifications as candidate electronic controllers of the equipment level as electronic controllers to be tested. The electronic controller at the equipment level is adopted for testing, so that the functional performance can be verified to be complete after the electronic controller is subjected to environmental stress. And, the number of the electronic controllers to be tested may be at least two.
The associated tester may trigger an compliance test command that may be used to detect the operational compliance of the electronic controller to be tested in an offshore area. The upper computer can receive the adaptability test instruction of the electronic controller to be tested in the offshore area, and determines various test rules including vibration test rules, damp-heat test rules, salt spray test rules and the like according to the environmental information of the offshore area. The vibration test rule indicates a test for the electronic controller when generating vibration in the south sea atmospheric environment; the damp-heat test rule indicates the test of the electronic controller in the high-temperature high-humidity atmospheric environment of the south China sea; salt spray test rules represent tests for electronic controllers in a high salinity environment in south China sea. The upper computer can cut according to the environmental profile of the electronic controller to be tested, and each test rule is determined.
Step S204, receiving an installation signal of experimental equipment corresponding to the electronic controller to be tested in the offshore area, and detecting a first running state of equipment functions of the electronic controller to be tested in a normal temperature environment.
The experimental equipment can be a test container, and the upper computer can control the environment configuration in the experimental equipment. So that it meets the atmospheric environment of south China sea. Wherein, the experimental equipment can be a laboratory environment test platform. The upper computer can perform environmental stress application on experimental equipment based on atmospheric quantitative simulation and vibration test of the south China sea. The experimental equipment can be specifically a comprehensive environment test box and a vibration test bed. The comprehensive environment test box mainly realizes quantitative simulation of natural atmospheric environment factors such as temperature, humidity, salt fog, solar radiation and the like, and the vibration test bed mainly realizes working conditions such as vibration and the like.
The electronic controller to be tested can be mounted on experimental equipment, and when the electronic controller to be tested is mounted on the experimental equipment, a mounting signal can be generated, and when the upper computer receives the mounting signal of the experimental equipment corresponding to the electronic controller to be tested in the offshore area, the experimental equipment can be in a normal temperature state at this moment, and the upper computer can detect the first running state of the functions of the equipment under the normal temperature environment of the electronic controller to be tested. The upper computer can test each function of the electronic controller to be tested under the normal temperature environment to obtain a first running state of the electronic controller to be tested.
And S206, configuring the test environment of the experimental equipment according to the vibration test rule, the salt spray test rule and the damp-heat test rule, and detecting the second running state of the equipment function of the electronic controller to be tested under the test environment.
After the electronic controller to be tested is tested in the normal temperature environment, the upper computer can reconfigure the environment of the experimental equipment, for example, the upper computer can configure the testing environment of the experimental equipment according to the vibration testing rule, the salt spray testing rule and the damp-heat testing rule. The experimental equipment is in the testing environment, so that the upper computer can detect the second running state of the equipment function of the electronic controller to be tested in the testing environment. In some embodiments, the upper computer may configure the experimental device according to each test rule, and after each test rule is configured, detect a second running state of the electronic controller to be tested in a test environment configured by the test rule; in some embodiments, the upper computer may also detect the second operation state in a test environment configured with the plurality of test rules after the experimental device is configured according to the plurality of test rules.
And step S208, switching the test environment of the experimental equipment to a normal temperature environment, and returning to the step of detecting the first running state of the equipment function of the electronic controller to be tested in the normal temperature environment until the preset end condition is met, and obtaining the working condition coupling test result of the electronic controller to be tested according to the first running state and the second running state.
After the upper computer detects the second running state of the electronic controller to be tested, the testing environment of the experimental equipment can be switched to a normal temperature environment, and the step of detecting the first running state of the function of the electronic controller to be tested in the normal temperature environment is returned, so that the electronic controller to be tested is circularly detected in different environments. The electronic controller has a set planned use time, and in this time, the electronic controller can undergo multiple environmental changes, so the cycle detection is to detect the adaptability of the electronic controller to be tested to withstand multiple environmental changes in the planned use time.
The upper computer can obtain a plurality of first running states and a plurality of second running states through multiple times of detection, and when the upper computer detects that the test meets the preset end condition, the upper computer can obtain a working condition coupling test result of the electronic controller to be tested according to the first running states and the second running states. For example, the condition coupling test result may include a first operation state and a second operation state corresponding to each cycle, and an adaptability result of the electronic controller to be tested in the south sea atmospheric environment determined based on the plurality of first operation states and the plurality of second operation states.
The preset ending condition may be determined based on the service time of the electronic controller to be tested. For example, in one embodiment, the preset end condition may be that the number of cycles of the test for the electronic controller to be tested is greater than or equal to a planned cycle threshold corresponding to the electronic controller to be tested. Wherein the planned cycle threshold is determined based on a planned usage time of the electronic controller under test. Specifically, the planned use time of the electronic controller to be tested may be one year, and then the planned cycle number of the electronic controller to be tested may be 4 times according to the number of changes of the south sea atmosphere environment within one year. In some embodiments, the above-mentioned preset end condition may be that the damage degree of the electronic controller to be tested reaches a preset damage threshold. For example, when the electronic controller to be tested cannot realize the main function, it is determined to stop the test.
According to the electronic controller working condition coupling test method based on the offshore atmospheric environment laboratory, the vibration test rule, the damp-heat test rule and the salt spray test rule are determined according to the environmental information of the offshore area based on the adaptability test instruction, the first operation state of the electronic controller to be tested in the normal-temperature environment of the experimental equipment is detected, the test environment of the experimental equipment is configured based on the multiple rules, the second operation state of the electronic controller to be tested in the test environment is detected, the normal-temperature environment is switched, and the working condition coupling test result of the electronic controller is obtained when the operation state is repeatedly detected until the preset ending condition is met. Compared with the traditional test performed through the material-level sample, the experimental device simulates the environment of the offshore area, and tests the running state of the electronic controller under different environments for multiple times, so that the accuracy of the electronic controller working condition coupling test based on the offshore atmosphere environment laboratory is improved.
In one embodiment, determining vibration test rules, damp heat test rules, and salt spray test rules based on environmental information of the offshore area includes: determining test vibration frequency and test vibration level aiming at the electronic controller to be tested as vibration test rules according to the vibration level information and the planned use time of the electronic controller to be tested; according to the temperature and humidity information, determining the test temperature, the test humidity and the damp-heat test time aiming at the electronic controller to be tested as damp-heat test rules; according to the salt spray information, determining test salt spray environment information, test salt spray time, test drying environment information and test drying time aiming at the electronic controller to be tested as salt spray test rules.
In this embodiment, the upper computer may determine each test rule of the electronic controller to be tested according to a plurality of conditions. The host computer can acquire environmental information of an offshore area, such as environmental information of south China sea. The salt fog environment information, the temperature and humidity information, the vibration level information and the like can be specifically included. The upper computer can determine the test vibration frequency and the test vibration level aiming at the electronic controller to be tested according to the vibration level information and the planned use time of the electronic controller to be tested. Specifically, the upper computer can increase the vibration test according to the working condition of the electronic controller to be tested, the upper computer can determine the platform vibration magnitude of the electronic controller to be tested according to the atmospheric environment of the south China sea, namely the vibration level information, and analyze the time of the electronic controller to be tested, namely the test vibration frequency, according to the service time of the electronic controller to be tested, so as to obtain the vibration test rule. In addition, in order to match the natural environmental stress, such as the test time of temperature, humidity, salt fog and the like, the upper computer can also adjust the test speed by adjusting the vibration magnitude, such as an acceleration test and the like.
The upper computer can also determine the test temperature, the test humidity and the damp-heat test time aiming at the electronic controller to be tested according to the temperature and humidity information, and the damp-heat test rule is obtained. Specifically, the upper computer can determine the test temperature to be 60 ℃ and the test humidity to be 95% RH according to the temperature and humidity information in the year of south China sea, and maintain for 96 hours in each detection to obtain the damp-heat test rule.
In salt spray test, the upper computer can regularly spray salt spray through control experimental equipment, and the running state of the electronic controller to be tested is determined through multiple detection of salt spray environment and dry environment. In the configuration process, the upper computer can also determine the test salt spray environment information, the test salt spray time, the test drying environment information and the test drying time aiming at the electronic controller to be tested according to the salt spray information, so as to obtain a salt spray test rule. The test salt spray environment information may include various types of information, among others. For example, in one embodiment, the upper computer may determine the salt spray temperature, the salt solution ph and the salt spray settlement amount for the electronic controller to be tested as the test salt spray environment information according to the salt spray information. The test dry environment information may also include various types of environment information. For example, in one embodiment, the upper computer may determine the drying temperature and the drying humidity for the electronic controller to be tested as the test drying environment information according to the salt spray information. Wherein the drying temperature means a temperature in a drying environment, and the drying humidity means a humidity in the drying environment.
Specifically, in the salt spray test, the upper computer can set the test spraying salt spray time and the test drying time to be 24 hours. In the salt spray stage, setting the salt spray temperature to 35+/-2 ℃; setting the concentration of the salt solution to be 5+/-1%; setting the pH value of the salt solution to be 6.5-7.2; setting the salt fog settlement amount to be 1.0 ml-3.0 ml/80cm < 2 > h. The temperature is set to 25+/-2 ℃ in the drying stage; the relative humidity was set at 45% ± 2%. Thereby obtaining the salt spray test rule.
Through the embodiment, the upper computer can simulate various test environments for experimental equipment through the environmental information of the offshore area, and test the running states of the electronic controller under different environments for multiple times, so that the accuracy of the working condition coupling test of the electronic controller based on the offshore atmosphere environment laboratory is improved.
