The input may be a parameter reflecting the operating state of the vertical separator, i.e. a parameter that needs to be monitored. And matching the parameters to be monitored with the data stored in the acquisition server and the relational database in a calculation module, and then sequentially verifying the types of the data matched with the parameters to be monitored. According to the physical characteristics of the vertical separator and the calculation requirements of the mathematical model, the normal state numerical value of each parameter to be monitored is limited in the numerical range, and meanwhile, the calculation unit of the parameter to be monitored is limited. And calculating the matched data of the parameters which need to be monitored and are limited by the checksum based on the related mathematical model, and outputting the calculation result through a calculation output module.
A checking module: the system comprises a test input module and a test output module, and the test module also internally contains values of normal states of all parameters to be monitored and analysis information of some abnormal values. The calculation result of the parameters needing to be monitored from the calculation module is input through the inspection input module, the calculation result is compared with the numerical values of the normal states corresponding to the parameters needing to be monitored and judged, the calculation result is displayed to be normal or abnormal, and when the calculation result is displayed to be abnormal, the reason of the abnormal is displayed at the same time. All the inspection results can be output to the alarm module through the inspection output module.
An alarm module: the alarm input module inputs the inspection result, classifies the inspection result and alarms in different modes according to different classifications.
It should be noted that there is a checking process before the calculation result is output, that is, it is determined whether there is an error in the calculation result, and then the calculation result is divided into two calculation results, i.e., an error and an error. Further, when the checking result shows that no error exists, the next monitoring period is directly started. And when the checking result shows that an error exists, outputting the calculation result with the error to a checking module, and further checking the calculation result, namely comparing and judging the calculation result with the value of the normal state corresponding to the parameter to be monitored. And when the judgment result is normal, directly entering the next monitoring period. When the judgment result is abnormal, analyzing the reason of the abnormality, and outputting the abnormal calculation result and the abnormal reason to an alarm module for classification and arrangement; specifically, according to the reason analysis of the abnormal calculation results, the abnormal calculation results with the same analysis result are divided into the 1 st class, the abnormal calculation results with different analysis results are divided into the 2 nd, 3 rd, … rd class and the n class, wherein n is larger than or equal to 2.
According to different classifications, the monitoring system can send different alarm prompts and display corresponding alarm information, wherein the alarm information comprises a calculation result and a corresponding analysis result, and the calculation result and the corresponding analysis result are abnormal.
In an optional embodiment of the present disclosure, as shown in fig. 2, the real-time monitoring system is adopted to monitor the operation state of the vertical separator in real time, and the monitoring method includes the following steps:

Checking the parameter types: the type of the data matched with the parameters to be monitored is checked in sequence, for example, whether the data is of a String type or a Number type, for example, the type of the designed ingress device should be the String type.
Parameter definition: according to the physical characteristics of the vertical separator and the calculation requirements of the mathematical model, the normal state numerical value of each parameter to be monitored is limited in the numerical range, and meanwhile, the calculation unit of the parameter to be monitored is limited. For example, a design margin factor, which defines a range of (0, 2), unitless.
Parameter matching, parameter type checking and parameter limiting are all completed in the computing module. If the data matched with the parameters to be monitored are not in accordance with the limited numerical range or the types of the parameters to be monitored are not matched, the results are output to the alarm module through the calculation module, and an alarm prompt is given to a user.
2) And (3) parameter calculation: and calculating the matched data of the parameters to be monitored based on the mathematical model, and checking whether the calculation result has errors. And according to the checking result, dividing the calculation result into two situations of error existence and error nonexistence. And when the checking result shows that no error exists, directly entering the next monitoring period. And when the checking result shows that an error exists, outputting the calculation result to a checking module, and further checking the calculation result, namely comparing and judging the calculation result with the value of the normal state of the corresponding monitoring parameter. When the judgment result is normal, directly entering the next monitoring period; and when the judgment result is abnormal, the inspection module starts to analyze the reason of the abnormality, then the inspection result is output to the alarm module, and the inspection result is further classified and sorted according to the reason of the abnormality in the alarm module.
3) And (4) checking and calculating results: some abnormal operating conditions of the vertical separator are judged by checking (whether normal or reasonable) the calculation results. And comparing the calculation result with the value of the normal state of each parameter to be monitored contained in the inspection module, and judging whether the calculation result is normal or abnormal. For example, in a series of parameters to be monitored, such as the inner diameter of an inlet nozzle, the inner diameter of a gas outlet nozzle, the diameter of a cylinder and the like of the vertical separator, which need to be judged whether the parameters are reasonable or not, the normal state value of the inner diameter of the inlet nozzle should be 0.31, the result calculated by the calculation module is 0.29, and if the value is smaller than the normal value, the inspection module displays that the result is an abnormal calculation result.
Analyzing an abnormal calculation result: and analyzing the abnormal calculation result according to the analysis information of some abnormal values contained in the inspection module, and outputting the analysis result and the abnormal calculation result to the alarm module. For example, if the reason why the analysis of the abnormal calculation result of the inner diameter of the inlet nozzle to obtain the error of the parameter to be monitored is related to the maximum gas volume flow rate and the maximum liquid volume flow rate may be related, the analysis result and the corresponding calculation result are output to the alarm module together.
And when the abnormal value does not exist in the test result, directly entering the next monitoring period.
4) And classifying the abnormal calculation results, and alarming in different modes according to different classifications.
In the alarm module, according to the analysis of the reasons of the abnormal calculation results, the abnormal calculation results with the same analysis results are divided into the 1 st class, the abnormal calculation results with different analysis results are divided into the 2 nd, 3 rd and … rd class, n is larger than or equal to 2.
