Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the order of execution, and the order of execution of the processes should be determined by the functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

Referring to fig. 1, an embodiment of the present invention provides a method for power-on self-test, which is applied to an industrial system, and the method includes:

step 101: in the case of starting up an industrial system, detection parameters of each of a plurality of detection points in the industrial system are acquired.

It should be noted that, the starting operation is a precondition in the starting self-checking flow, and starting the industrial system is that the industrial system executes the starting operation. That is, the industrial system that is not started is powered up to operate normally. The industrial system is a system for industrial production, and the detection points are detection devices, such as a temperature detection device, a pressure detection device, a gas flow detection device, and the like, which are arranged at different positions of the industrial system and are used for detecting various parameters. The detection side parameter is a parameter detected by a detection point or a parameter after the detected parameter is subjected to preset processing. That is, the detection parameter is not necessarily a detection value obtained by the detection device, and may be a value obtained by processing the detection value. For example, the detecting device is a temperature detecting device, and the detecting parameter may be a detected temperature value or a temperature difference between the detected temperature value and a set temperature value. The determination mode of the detection parameters of the detection points is already preset, and only the detection parameters output by the detection points need to be obtained.

The starting-up detection process is a continuous process, and can be continuously carried out or the detection is carried out for a few times to obtain a detection parameter. Thus, for the same detection point, the detection parameters of the detection point are a series of detection parameters.

Step 102: and combining detection parameters of each detection point according to the detection point combination corresponding to each detection item in the preset self-detection information to obtain the parameter combination corresponding to each detection item.

It should be noted that the preset self-checking information is self-checking information preset in the industrial system. Here, in order to satisfy the power-on self-test requirement of the industrial system, a plurality of test items may be set based on the power-on self-test requirement of the industrial system, that is, which test items need to be tested, and a plurality of different test points (test point combinations) for determining whether the test item is abnormal may be set for each test item. Specifically, the detection point combination corresponding to the detection item includes a combination of a plurality of detection point compositions for determining whether the detection item is abnormal. One detection item is one detection item, and can also be a detection item. The different detection items in the starting-up self-test process are equivalent to different physical examination items in the physical examination process, and the difference is that the invention detects the industrial system and the specific content of the detection items is also different.

Of course, a test item may also be understood as requiring a test of a certain hardware device itself or its operating parameters in the industrial system. It is understood that the combination of detection points corresponding to the detection items may further include a combination of a plurality of detection point compositions for determining whether the target device is abnormal. The target device is a target device associated with the detection item in the industrial system.

The combination of the detection point combinations to which each parameter belongs in the parameter combination is the same as the detection point combination corresponding to the detection item of the corresponding parameter combination. For example, the combination of detection points corresponding to the first detection item includes a first detection point and a second detection point, where the detection parameter of the first detection point is a first detection parameter, and the detection parameter of the second detection point is a second detection parameter, and the obtained combination of parameters corresponding to the first detection item includes the first detection parameter and the second detection parameter.

Step 103: for each parameter combination, determining the detection result of the detection item of the corresponding parameter combination according to the parameter combination.

It should be noted that the number of parameter combinations is plural, so that a plurality of detection results can be obtained, where each detection result corresponds to one parameter combination, and the detection result is a detection result of a detection item corresponding to the parameter combination. Here, the detection result of the detection item may be whether the detection item is abnormal or whether a target device associated with the detection item is abnormal. Preferably, a detection result of abnormal bearing of the alarm information can be adopted, and if no abnormality is found in the detection item or the target equipment, the alarm information is not generated.

It may be appreciated that, when determining the detection result according to the parameter combination, a detection policy may be preset, and the detection result may be determined based on each detection parameter and the detection policy in the parameter combination. Specifically, each detection point combination in the preset self-detection information corresponds to two different detection results, namely a first detection result and a second detection result, and the different detection results correspond to different parameter conditions, namely a first parameter condition and a second parameter condition. When the parameter combination accords with the first parameter condition, the detection result of the detection item corresponding to the parameter combination is a first detection result; when the parameter combination accords with the second parameter condition, the detection result of the detection item corresponding to the parameter combination is a second detection result.

Step 104: and generating self-checking result information of the industrial system according to the detection results of the detection items.

It should be noted that, the detection results of each detection item are determined in the starting-up self-checking process of the industrial system, and the detection results are summarized to generate self-checking result information of the industrial system, so that a user can acquire each detection result when checking the self-checking result information.

under the condition that each functional subsystem of the industrial system is started, respective detection parameters of a plurality of detection points in each functional subsystem are acquired.

It should be noted that an industrial system may be functionally divided into a plurality of functional subsystems. Different functional subsystems have different functions in an industrial system, and the industrial system completes industrial production through mutual cooperation among a plurality of functional subsystems. Here, each detection point in the industrial system will be distributed in each functional subsystem according to the division of the functional subsystems. Thus, for each functional subsystem, detection points in the functional subsystem are used to detect various parameters of the functional subsystem.

It will be appreciated that in the case of an industrial system comprising a plurality of functional subsystems, the detection of the different functional subsystems may be accomplished by turning on the different functional subsystems through different actions (operations). As shown in fig. 2, a flowchart of some steps of a method for power-on self-test is shown, in which after an industrial system is powered on, different functional subsystems are turned on based on different action settings, and only the processing procedure after one functional subsystem is turned on is shown in fig. 2 because the processing procedure after the different functional subsystems are similar. The following describes the processing procedure after the function subsystem is turned on:

After the function subsystem is started, a parameter combination 1 is obtained based on detection point combinations corresponding to the first detection items in preset self-checking information, and then whether the first detection items are abnormal or not is judged by using the parameter combination 1. Based on the detection point combination corresponding to the performance detection 1 (second detection item) in the preset self-detection information, a parameter combination 2 (a combination of the detection parameter 1 and the parameter combination 1, not shown in fig. 2) is obtained, and then, whether the second detection item is abnormal is determined by using the parameter combination 2. Based on the detection point combination corresponding to the performance detection 2 (third detection item) in the preset self-detection information, a parameter combination 3 (a combination of the detection parameter 1, the detection parameter 2, and the parameter combination 1, not shown in fig. 2) is obtained, and then, whether the third detection item is abnormal is determined by using the parameter combination 3. It is to be understood that the detection items are not limited to the three detection items in fig. 2, and the detection process of each detection item may be performed simultaneously or sequentially from top to bottom.

Generating self-checking result information of the industrial system according to the detection result of each detection item, wherein the self-checking result information comprises:

and determining the self-checking result of each functional subsystem according to the detection result of each detection item.

It should be noted that the self-test result of the functional subsystem includes a test result determined based on a parameter combination of the test parameters of the test points in the functional subsystem. The detection results corresponding to the functional subsystem represent the operation condition of the functional subsystem, and whether and where the functional subsystem has problems can be determined through the detection results. The function subsystem to which the detection item belongs is the function subsystem to which each detection point in the detection point combination corresponding to the detection item belongs.

It should be noted that, the self-checking results of the respective functional subsystems are summarized together as self-checking result information of the industrial system. Therefore, when the user checks the self-checking result information, the user can know the self-checking result of each functional subsystem.

In the embodiment of the invention, the industrial system is divided into a plurality of functional subsystems according to functions, and then the self-checking result of each functional subsystem is determined based on the detection result of each detection item, and the self-checking result of each functional subsystem is summarized into the self-checking result information of the industrial system, so that the division of intermediate granularity is realized, and the detection result of each detection item is prevented from being directly used as the self-checking result information of the industrial system.

Optionally, where the industrial system is a crystal pulling system, the functional subsystem comprises an inert gas subsystem, the sensed parameter comprises: inert gas flow bias, inert gas pressure, and furnace pressure, wherein the inert gas flow bias comprises a difference between an inert gas flow set point and an inert gas flow detection value;

it should be noted that the crystal pulling system may be a system that uses the Czochralski method to pull single crystal silicon in a single crystal furnace. The inert gas refers to an inert gas, such as argon, that needs to be introduced into the furnace during operation of the crystal pulling system, but is not limited thereto. The inert gas pressure is the pressure of inert gas in the inert gas pipeline, and the furnace pressure is the furnace pressure of the single crystal furnace.

The detection item corresponding parameter combination comprises:

inert gas flow deviation and inert gas pressure corresponding to inert gas pipeline detection items;

inert gas flow deviation, inert gas pressure and furnace pressure corresponding to the furnace pressure detection items.

It can be understood that, when the detection point to which the inert gas flow deviation belongs is a first detection point, the detection point to which the inert gas pressure belongs is a second detection point, and the detection point to which the furnace pressure belongs is a third detection point, the detection point combination corresponding to the inert gas pipeline detection item in the preset self-detection information includes the first detection point and the second detection point; the detection point combination corresponding to the furnace pressure detection item comprises a first detection point, a second detection point and a third detection point. Thus, combinations of the above parameters can be obtained.

According to the parameter combination, determining a detection result of a detection item corresponding to the parameter combination, including:

and under the condition that the deviation of the inert gas flow is larger than a first threshold value and the condition that the inert gas pressure changes along with time does not accord with a first target change curve, the detection result of the inert gas pipeline detection item is that the inert gas pipeline is abnormal. Here, the first threshold value is a preset value, and when the deviation of the inert gas flow is larger than the first threshold value, the inert gas flow set value and the inert gas flow detection value are larger in difference, and the possibility of abnormality of the inert gas pipeline is indicated; when the condition of the inert gas pressure changing along the time does not accord with the first target change curve, the possibility of abnormality of the inert gas pipe is also indicated. Therefore, in the case where both are present, it can be regarded as an abnormality of the inert gas pipe. It is noted that the first target profile is a profile of inert gas pressure at normal start-up of the inert gas subsystem. The condition that the inert gas pressure changes with time can be understood as a curve generated based on the change of the inert gas pressure with time, the curve is compared with a first target change curve, and if the curve is inconsistent, the condition that the inert gas pressure changes with time does not accord with the first target change curve; if so, the pressure of the inert gas changes with time to conform to the first target change curve.

When the deviation of the inert gas flow is smaller than or equal to a first threshold value, the condition that the inert gas pressure changes along with time accords with a first target change curve, and the condition that the furnace pressure changes along with time does not accord with a second target change curve, the detection result of the furnace pressure detection item is that the flowmeter is abnormal. Here, if the inert gas flow deviation is equal to or less than the first threshold value and the inert gas pressure changes with time, the flow meter abnormality is described if the furnace pressure does not change with time, in accordance with the first target change curve. The second target change curve is a change curve of the furnace pressure when the inert gas subsystem is started normally.

An example is described below in which the inert gas is argon. Here, an argon flow (argon flow set value) is preset, the corresponding furnace pressure change is observed, analysis is performed based on the corresponding data collected in advance, and key data such as the furnace body size, the argon valve opening size, the pressure rising amplitude and the like are analyzed, so that whether the argon system is normal can be obtained. As shown in fig. 3, a flow chart of a step of a start-up self-test of the argon subsystem is shown, wherein after the start-up of the argon subsystem, a gas pressing valve is opened, a parameter combination 1 is obtained based on a detection point combination corresponding to an argon gas pipeline detection item in preset self-test information, and then whether the argon gas pipeline detection item is abnormal (whether a condition that a deviation exists between an argon gas flow set value and an argon gas flow detection value and the argon gas pressure is abnormal is met or not is judged by using the parameter combination 1). Based on the detection point combination corresponding to the furnace pressure detection item in the preset self-checking information, a parameter combination 2 (a combination consisting of the furnace pressure and the parameter combination 1, not shown in fig. 3) is obtained, and then, whether the furnace pressure detection item is abnormal or not is judged by using the parameter combination 2 (whether the condition of the change of the furnace pressure with time accords with a second target change curve or not is judged under the condition that the set value of the argon flow is not deviated from the detection value of the argon flow and the argon pressure is not abnormal).

In the embodiment of the invention, the inert gas subsystem is subjected to self-inspection in the crystal pulling system, and the running condition of the inert gas subsystem is accurately determined based on the parameter combination corresponding to the inert gas subsystem.

Optionally, where the industrial system is a crystal pulling system, the functional subsystem includes a heating subsystem, the sensed parameter includes: the power supply cabinet comprises heating power deviation, first operation information representing the operation condition of the power supply cabinet and furnace temperature, wherein the heating power deviation comprises a difference value between a heater power set value and a heater power detection value;

the detection item corresponding parameter combination comprises:

heating power deviation and first operation information corresponding to the power cabinet detection item;

heating power deviation, first operation information and furnace temperature corresponding to the heater detection items;

under the condition that the heating power deviation is larger than a second threshold value and the first operation information represents the abnormality of the power cabinet, the detection result of the power cabinet detection item is the abnormality of the power cabinet;

It should be noted that the third target profile is the profile of the furnace temperature at normal start-up of the inert gas subsystem. The process of determining the detection result of the heating subsystem in the embodiment of the present invention is similar to the process of determining the detection result of the inert gas subsystem in the foregoing embodiment, and the difference is that the targets aimed at by the two are different, that is, the two aimed at different functional subsystems have different detection parameters and parameter combinations, which are not repeated here. Referring to fig. 4, a flowchart of a step of power-on self-test of the heating subsystem is shown, in which after the heating subsystem is powered on, heating power is set, a parameter combination 1 is obtained based on a detection point combination corresponding to a power cabinet detection item in preset self-test information, and then whether the power cabinet detection item is abnormal (whether a condition that a power set value deviates from a power detection value and the power cabinet is abnormal is satisfied) is determined by using the parameter combination 1. Based on the detection point combination corresponding to the heater detection item in the preset self-checking information, a parameter combination 2 (a combination consisting of the furnace temperature and the parameter combination 1, not shown in fig. 4) is obtained, and then, whether the heater detection item is abnormal or not is judged by using the parameter combination 2 (whether the condition of the change of the furnace temperature along with time accords with a third target change curve or not is judged under the condition that the power set value and the power detection value are not deviated and the power cabinet is not abnormal or not).

In the embodiment of the invention, the heating subsystem is subjected to self-inspection in the crystal pulling system, and the running condition of the heating subsystem is accurately determined based on the parameter combination corresponding to the heating subsystem.

Optionally, where the industrial system is a crystal pulling system, the functional subsystem comprises a crystal lifting subsystem, the detection parameters include: the system comprises a crystal lifting speed deviation, communication information representing the crystal lifting communication condition and second operation information representing the operation condition of an encoder, wherein the crystal lifting speed deviation comprises a difference value between a crystal lifting speed set value and a crystal lifting speed detection value;

the detection item corresponding parameter combination comprises:

the crystal lifting motor detection item corresponds to the crystal lifting speed deviation and the communication information;

the encoder detects the crystal rise speed deviation, the communication information and the second operation information corresponding to the detection items;

It should be noted that, in the embodiment of the present invention, the process of determining the detection result of the crystal lifting subsystem is similar to the process of determining the detection result of the inert gas subsystem in the previous embodiment, and the difference is that the targets of the two are different, that is, the two are different for different functional subsystems, and have different detection parameters and parameter combinations, which are not repeated here. Referring to fig. 5, a flowchart of a step of performing a power-on self-test of the lift-off subsystem is shown, in which after the power-on of the lift-off subsystem is performed, the lift-off speed is set, a parameter combination 1 is obtained based on a detection point combination corresponding to a lift-off motor detection item in preset self-test information, and then whether the lift-off motor detection item is abnormal or not is determined by using the parameter combination 1 (whether a condition that a set value of the lift-off speed deviates from a detection value of the lift-off speed and the lift-off communication is abnormal is satisfied is determined). Based on the detection point combination corresponding to the encoder detection item in the preset self-checking information, a parameter combination 2 (a combination consisting of the encoder operation information and the parameter combination 1, not shown in fig. 5) is obtained, and then, whether the encoder detection item is abnormal or not is judged by using the parameter combination 2 (whether the position of the encoder is unchanged and the signal input is normal or not is judged under the condition that the set value of the crystal rise speed is not deviated from the detection value of the crystal rise speed and the crystal rise communication is not abnormal).

In the embodiment of the invention, the crystal lifting subsystem is subjected to self-inspection in the crystal pulling system, and the running condition of the crystal lifting subsystem is accurately determined based on the parameter combination corresponding to the crystal lifting subsystem.

Optionally, where the industrial system is a crystal pulling system, the functional subsystem comprises a dry pump subsystem, the sensed parameter comprises: the system comprises a dry pump frequency deviation, third operation information representing the operation condition of the dry pump and a furnace pressure, wherein the dry pump frequency deviation comprises a difference value between a dry pump operation frequency set value and a dry pump operation frequency detection value;

the detection item corresponding parameter combination comprises:

the dry pump detection item corresponds to dry pump frequency deviation and third operation information;

the furnace body detection item corresponds to the dry pump frequency deviation, the third operation information and the furnace pressure;

under the condition that the deviation of the frequency of the dry pump is larger than a fourth threshold value and the third operation information represents that the dry pump is abnormal, the detection result of the dry pump detection item is that the dry pump body is abnormal;

and under the conditions that the deviation of the dry pump frequency is smaller than or equal to a fourth threshold value, the third operation information represents that the dry pump is normal, and the change of the furnace pressure along with time does not accord with a second target change curve, the detection result of the furnace body detection item is abnormal.

It should be noted that, in the embodiment of the present invention, the process of determining the detection result of the dry pump subsystem is similar to the process of determining the detection result of the inert gas subsystem in the previous embodiment, and the difference is that the targets of the two are different, that is, the two are different for different functional subsystems, and have different detection parameters and parameter combinations, which are not repeated here. Referring to fig. 6, a flowchart of a step of a self-test of a dry pump subsystem is shown, in which after the dry pump subsystem is started, a dry pump frequency is set, a parameter combination 1 is obtained based on a detection point combination corresponding to a dry pump detection item in preset self-test information, and then whether the dry pump detection item is abnormal is determined by using the parameter combination 1 (whether a condition that a set value of the dry pump frequency deviates from a detection value of the dry pump frequency and the dry pump is abnormal is satisfied). Based on the detection point combination corresponding to the furnace body detection item in the preset self-detection information, a parameter combination 2 (a combination consisting of the furnace pressure and the parameter combination 1 is not shown in fig. 6) is obtained, and then, whether the furnace body leaks air or not is judged by using the parameter combination 2 (whether the condition of the change of the furnace pressure along time accords with a second target change curve or not is judged under the condition that the set value of the dry pump frequency does not deviate from the detection value of the dry pump frequency and the dry pump does not see abnormality).

In the embodiment of the invention, the self-checking of the dry pump subsystem is carried out in the crystal pulling system, and the running condition of the dry pump subsystem is accurately determined based on the parameter combination corresponding to the dry pump subsystem.

determining detection results corresponding to the functional subsystems based on detection items corresponding to the functional subsystems for each functional subsystem;

and aiming at each functional subsystem, determining the self-checking result of the functional subsystem according to the corresponding detection result combination of the functional subsystem.

It is understood that the combination of the detection results may be a simple combination and summary, or may be a result of further judgment based on a plurality of detection results.

In the embodiment of the invention, by combining the detection results in the functional subsystem, a more accurate self-checking result of the functional subsystem can be obtained.
