[0002] During the testing of a certain product, both the product and the testing process system are at risk of leakage of toxic, harmful, flammable and explosive gases. Therefore, the testing environment is at risk of toxicity, corrosion, fire, explosion, high temperature and high pressure. Operators need to frequently perform inspections and maintenance in this environment. Therefore, it is necessary to diagnose test faults in real time and accurately to provide fault warnings to operators and ensure their safety.

[0003] At present, the conventional test safety monitoring method of test fault warning method mainly monitors a single indicator of test environment safety, which affects the accuracy of fault diagnosis, thereby making wrong fault warnings to operators and affecting the safety of operators. Summary of the invention

[0006] According to the alarm value scoring rules, the channel score of each monitoring indicator of each subsystem is counted, and the weighting coefficient of each subsystem is obtained. The score of each subsystem is weighted and superimposed according to the weighting coefficient of each subsystem to obtain the total score of each subsystem. It is determined whether the total score of each subsystem is within the test safety score range. If not, the fault type is determined according to the test safety score range, and an early warning is issued according to the fault type.

[0007] Preferably, the alarm value scoring rule is:

[0010] Rule 3: When multiple channels of the same subsystem alarm, and the indicators are related, the indicator scores are added together; if the indicators are not related, the alarm value is the maximum value of the indicator scores;

[0011] Rule 4: If channels of different subsystems alarm at the same time and the indicators are related, the subsystem score is the value of the superposition of the related indicators of different subsystems multiplied by the number of related indicators, and then added to the score of the related indicators within each subsystem, which is the alarm value of each subsystem; if the indicators are not related, the calculation method of the score of each subsystem refers to Rule 3.

[0012] Preferably, the subsystems include a product monitoring subsystem, a test environment monitoring subsystem, a process monitoring subsystem, a test support monitoring subsystem and a natural environment monitoring subsystem.

[0013] Preferably, the monitoring indicators of the product monitoring subsystem include the appearance of the test product, the product status and the internal microenvironment of the product; the monitoring indicators of the test environment monitoring subsystem include the test environment concentration, temperature and humidity, flame and smoke; the monitoring indicators of the process monitoring subsystem include process containers and pipelines and process valves and equipment; the monitoring indicators of the test support monitoring subsystem include water supply, power supply, heating and gas supply; the natural environment monitoring subsystem includes earthquakes, floods and fires.

[0017] The fault warning module is used to count the channel scores of each monitoring indicator of each subsystem according to the alarm value scoring rules, obtain the weighting coefficient of each subsystem, weight the scores of each subsystem according to the weighting coefficient of each subsystem, and superimpose them to obtain the total score of each subsystem, and determine whether the total score of each subsystem is within the test safety score range. If not, determine the fault type according to the test safety score range, and issue a warning based on the fault type.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention and implement it, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the scope of protection of the present invention.

[0028] Example

[0029] The present invention provides a test failure early warning method, specifically as follows Figure 1 As shown, the following steps are included:

[0030] Step 1: Divide the test safety monitoring system into multiple subsystems. Each subsystem includes multiple monitoring indicators, and each monitoring indicator is collected through multiple channels.

[0031] The test safety monitoring system adopts a hierarchical and progressive approach, such as Figure 2 As shown in the figure, the outermost part is the natural environment monitoring subsystem, the middle part is the test support monitoring subsystem, the process monitoring subsystem and the test environment monitoring subsystem, and the core is the product monitoring subsystem. This structure can fully cover the test environment safety monitoring, achieving both independent warning of any level and correlation analysis between multi-level indicators.

[0032] The detailed architecture of the test safety monitoring system of the present invention is shown in Figure 3 The test safety monitoring system consists of a product monitoring subsystem, a process monitoring subsystem, a test environment monitoring subsystem, a test guarantee monitoring subsystem and a natural environment monitoring subsystem. Among them, the product monitoring subsystem mainly realizes the monitoring of the test product appearance, product status and product internal microenvironment; product appearance monitoring mainly realizes the monitoring of appearance rust and cracks, the monitoring indicators of product status monitoring mainly include pressure, temperature and strain, and product microenvironment monitoring mainly includes product internal environment leakage monitoring. The test environment monitoring subsystem mainly realizes the monitoring of product test environment concentration, temperature and humidity, flame and smoke. The process monitoring subsystem includes process container and pipeline monitoring, process valve and equipment monitoring. The process container and pipeline monitoring mainly realizes the monitoring of pressure, temperature and other indicators of process containers and pipelines, and the process valve and equipment monitoring mainly realizes the monitoring of valve switch status and equipment operation status. The guarantee monitoring subsystem mainly includes the status monitoring of water, heating, electricity and other systems that provide guarantee for the test environment. Natural environment monitoring mainly includes earthquake, flood and fire monitoring.

[0033] The test safety monitoring system collects the sensor signals through the acquisition device. The test safety monitoring server conducts comprehensive diagnosis on the data of each subsystem, and then links the graded and classified alarm devices arranged on site to issue an alarm. Figure 4 shown.

[0034] Step 2: Formulate scoring rules for the alarm value of each monitoring indicator based on whether each monitoring indicator is alarmed.

[0035] The present invention assigns scores to various indicator alarms of a certain test safety monitoring system, as shown in Table 1:

[0036] Among them, the total number of channels in Table 1 refers to the number of channels for collecting a certain type of indicator. For example, if there are 4 channels for collecting product appearance at the same time, and 4 channels alarm at the same time, it means that the product appearance alarm (value is 1), so the score of each channel is 0.25; the related indicators of the same system refer to the related indicators in the same subsystem. Correlation means that when one indicator changes, another indicator will also change at the same time, which can be used as a comparison. Related system indicators mean that the subsystems are related. When one subsystem changes, the other subsystem will also change. Taking the product monitoring subsystem as an example, the temperature and pressure inside the subsystem are related indicators. When the product temperature changes, the pressure will also change. Some indicators of the product monitoring subsystem and the test environment monitoring subsystem are related, such as product concentration and environmental concentration. When the product leaks, the product concentration indicator will alarm, and when the leakage is large, it will cause an environmental concentration alarm; similarly, when the process pipeline leaks, the concentration indicator in the test environment monitoring subsystem will alarm, which may also cause the product concentration indicator to alarm.

[0037] Table 1 Score assignment for each indicator alarm of a test safety monitoring system

[0038]

[0039] Based on Table 1, the scoring rules for the alarm values ​​of each indicator of each subsystem are designed as follows:

[0040] Rule 1: If an alarm occurs in the channel, the indicator score is 1, and if it is normal, the indicator score is 0;

[0041] Rule 2: If an alarm occurs in one channel, emergency treatment is required, and the score of this indicator is 1; if an alarm occurs in two channels at the same time, it is considered an alarm, and the score of this indicator is 0.5; if an alarm occurs in n channels at the same time, it is confirmed as an alarm, and the score of this indicator is 1 / n;

[0042] Rule 3: When multiple channels of the same subsystem alarm, and the indicators are related, the indicator scores are added together; if the indicators are not related, the alarm value is the maximum value of the indicator scores;

[0043] Rule 4: If channels of different subsystems alarm at the same time and the indicators are related, the subsystem score is the value of the superposition of the related indicators of different subsystems multiplied by the number of related indicators, and then added to the score of the related indicators within each subsystem, which is the alarm value of each subsystem; if the indicators are not related, the calculation method of the score of each subsystem refers to Rule 3.

[0044] Step 3: Count the score of each subsystem according to the alarm value scoring rule, obtain the weighting coefficient of each subsystem, weight the score of each subsystem according to the weighting coefficient of each subsystem, and then superimpose them to obtain the test safety score range, and determine the fault type according to the test safety score range.

[0045] The weighting coefficient of each subsystem is shown in Table 2, specifically: the weighting coefficient of the product monitoring subsystem is 100, the weighting coefficient of the test environment monitoring subsystem is 10, the weighting coefficient of the process monitoring subsystem is 10, the weighting coefficient of the test assurance monitoring subsystem is 0.1, and the weighting coefficient of the natural environment monitoring subsystem is 0.01.

[0047] Subsystem Weighting coefficient Product Monitoring 100 Test environment monitoring 10 Process Monitoring Subsystem 10 Security system monitoring 0.1 Natural environment monitoring 0.01

[0048] When two faults occur, each subsystem executes its own alarm according to Table 3, each subsystem calculates its own score, and then executes different plans according to Table 4.

[0049] In order to facilitate understanding of the method of the present invention, the following case will be used for illustration:

[0050] Take a test environment product indicator monitoring subsystem and a test environment monitoring subsystem each with an alarm, and other subsystems without an alarm as an example for score calculation. The alarm signals are shown in Table 1. Two of the three product pressure channels generate an alarm, that is, a confirmed pressure alarm; one of the two channel concentrations confirms an alarm, and one channel of the test environment related indicators alarms. The calculation method for the total score A of the product monitoring subsystem is as follows (according to the method in Table 1):

[0051] Table 3 Classification of alarms and alarm cancellation methods

[0052]

[0053] Table 4 Score ranges and possible fault types

[0054]

[0055] (1) Calculate according to the "rules for assigning points to alarm values ​​for each subsystem indicator". Among the product indicators, the pressure has two channels for alarm, 0.5+0.5=1.0.

[0056] (2) When a concentration alarm occurs in one channel and a pressure alarm occurs due to related indicators, the rule “When indicators of multiple channels of the same subsystem alarm, if the indicators are related, the scores are added together” is used, +0.5.

[0057] (3) One channel alarm for concentration and one channel alarm for environmental related indicators, that is, "different subsystem indicators alarm at the same time, the indicators are related, then the subsystem score is the value of the superposition of the different subsystem related indicators multiplied by the number of related indicators", the concentration score is 0.5 + the environmental indicator score is 0.5, the number of related indicators is 2, so it is (0.5+0.5)×2.

[0058] Then the total score A of the product monitoring subsystem is: A=1.0+0.5+(0.5+0.5)×2=3.5.

[0059] At the same time, in the test environment indicators, if one of the two channel concentration sensors alarms, the calculation method of the total score B of the test environment monitoring subsystem is as follows (according to the method in Table 1):

[0060] (1) Environmental concentration 1 channel alarm, score 0.5.

[0061] (2) One channel alarm for the product concentration of the relevant subsystem, with a score of 0.5.

[0062] (3) There are two channels for related indicators, so the total score is (0.5+0.5)*2.

[0063] Then the total score B of the test environment monitoring subsystem is B=(0.5+0.5)×2=2.

[0064] The safety value of the test system is C=100A+10B=370.

[0065] The present invention also provides a test fault diagnosis system, comprising:

[0066] A data acquisition module is used to divide the test safety monitoring system into multiple subsystems, each subsystem includes multiple monitoring indicators, and each monitoring indicator is collected through multiple channels;

[0067] The fault warning module is used to count the channel scores of each monitoring indicator of each subsystem according to the alarm value scoring rules, obtain the weighting coefficient of each subsystem, weight the scores of each subsystem according to the weighting coefficient of each subsystem, and superimpose them to obtain the total score of each subsystem, and determine whether the total score of each subsystem is within the test safety score range. If not, determine the fault type according to the test safety score range, and issue a warning based on the fault type.

[0068] The present invention also provides a computer device, comprising a memory and a processor; the memory stores a computer program, and the processor is used to run the computer program in the memory to execute the test fault warning method described in the claims.
