Example one
In order to reduce interference caused by excessive alarm information of an refining device to judgment of operators, improve accuracy of operation risk early warning of the refining device and further ensure safety of a production process of the refining device, as shown in fig. 1, an embodiment of the invention provides an operation risk early warning method of the refining device, which comprises the following steps:
s11, acquiring alarm information data of each monitoring variable through a DCS;
the inventor finds that in the prior art, operators often need to face a great amount of alarm information data to indicate which monitoring variables are abnormal currently; at this time, on one hand, operators are required to judge the risk degree of the indexes corresponding to each monitoring variable, and on the other hand, the current operation risk of the refining device is required to be evaluated according to the generation frequency and the quantity of the alarm information data; the requirement on the judgment capability of operators is high, so that misjudgment is easy to occur; in addition, when the alarm information data corresponding to some important monitoring variables are ignored or omitted, the operation accidents of the high refining device are likely to be caused directly.
For the above reasons, in the present application, the alarm information data of each monitored variable is specifically processed, and first, the alarm information data of each monitored variable needs to be acquired through the DCS.
In practical application, a specific way of acquiring the alarm information data of each monitoring variable through a DCS operator station or an engineer station may be as follows: and setting configuration at a DCS operator station or an engineer station, setting a real-time alarm printing mode according to a printer driver, and outputting the alarm information data through a serial port interface. And then, after the data connection with the RS232 interface of the DCS operator station, the real-time alarm information data sent by the DCS operator station can be received in real time.
S12, constructing alarm information records of all monitoring variables according to the alarm information data; the field of the alarm information record comprises one of the bit number, description, real-time value, alarm state, time, alarm type, alarm mark and priority of the monitoring variable and any combination thereof;
in practical applications, microsoft SQL Server database may be deployed on a Server of the operational risk early warning software system of the refinery apparatus to manage alarm information records. An alarm information record analysis model is established by inserting a trigger into the alarm information record data table to carry out complete alarm information record combination and store the complete alarm information record combination into a standard alarm information record data table. A complete alarm information record may include: bit number, description, real-time value, alarm status, alarm type, priority, start time, acknowledgement time, end time, etc.
S13, determining a working condition risk result of the refining device according to a preset algorithm by taking the alarm information record as a parameter; the preset algorithm comprises the following steps: setting a quantity threshold value for generating the alarm information records in a preset time length, and/or setting a duration threshold value for generating the alarm information records in the preset time length.
The inventor finds that the number of alarm information records generated within a preset time period and the duration of the alarm information records generated within the preset time period are important basis for judging the current working condition risk of the refining device, and if the number of the alarm information records generated within a preset time period is large or the duration of the alarm information records generated within a preset time period is long, the current working condition risk of the refining device is very high, and timely alarming and processing are needed. It should be noted that the preset time period in the embodiment of the present invention may be set by a person skilled in the art according to actual needs or obtained through a limited number of experiments, and is not limited specifically herein.
In addition, in the invention, because the alarm information record also comprises the bit number, description, real-time value, alarm state, time, alarm type, alarm mark and priority of the corresponding monitoring variable, the working section mark or equipment mark corresponding to the monitoring variable with high working condition risk can be included in the working condition risk generation result, thereby realizing the rapid positioning of the specific working section or equipment with high working condition risk and further improving the efficiency and effect of risk or fault investigation.
Sometimes, a plurality of alarm information data are continuously generated by the same monitoring variable within a short time, (the time interval between the ending time of the first alarm and the starting time of the second alarm is small), and as the alarm information data are generally abnormal aiming at the same parameter, the plurality of alarm information data which are too frequent are counted into one to meet the statistical requirement. Therefore, further, in the embodiment, the misjudgment of the working condition risk judgment of the refining device caused by repeated alarm can be reduced by carrying out delay processing on a large number of repeated alarms generated by the DCS; it should be noted that, the specific setting of the time interval between the alarm information data and the setting of the number of the alarm information data to be combined may be determined by those skilled in the art according to actual situations or limited experiments, and the specific setting is not limited herein.
In summary, in the present invention, the alarm information data is processed again; firstly, generating an alarm information record which can be stored in a database according to the alarm information data; then, the alarm information record is used as a parameter to generate a working condition risk result of the refining device according to a preset rule, so that an operator can directly obtain a judgment result of the current working condition risk of the refining device; by the aid of the method and the device, the possibility of misjudgment caused by manual judgment of operators when the refining device generates a large amount of alarm information can be avoided, the accuracy of running risk early warning of the refining device is improved, and safety of the refining device in the production process is ensured.
Example two:
on the basis of the first embodiment, in the embodiment of the present invention, the method may further include the steps of:
s121, judging whether alarm information data of each monitoring variable belongs to key alarm or not according to a preset judgment rule; the preset judgment rule comprises a preset condition; the preset conditions comprise that SIL rating of related monitoring variables of the interlocking loop is larger than SIL0, and/or risk level in HAZOP analysis report is larger than 3;
s122, grouping the monitoring variables by taking workshop sections and equipment as units; and according to the alarm information record corresponding to each workshop section or the equipment, constructing an alarm information record set of each workshop section or the equipment.
In practical applications, as shown in fig. 2, the specific steps in the embodiment of the present invention may be as follows:
s11, acquiring alarm information data of each monitoring variable through a DCS operator station;
in the application, the alarm information data of each monitoring variable is specifically processed, and firstly, the alarm information data of each monitoring variable needs to be acquired through a DCS operator station.
In practical application, the specific way of obtaining the alarm information data of each monitoring variable through the DCS operator station may be: and setting configuration in a DCS operator station, setting a real-time alarm printing mode according to a printer driving program, and outputting alarm information data through a serial port interface. And then, after the data connection with the RS232 interface of the DCS operator station, the real-time alarm information data sent by the DCS operator station can be received in real time.
S12, constructing alarm information records of all the monitoring variables according to the alarm information data; the field of the alarm information record comprises one of the bit number, description, real-time value, alarm state, time, alarm type, alarm mark and priority of the monitoring variable and any combination thereof;
in practical application, a microsoft SQL Server database may be deployed on a Server running the risk early warning software system of the refinery device to manage alarm information records. A complete alarm information record may include: bit number, description, real-time value, alarm status, alarm type, priority, start time, acknowledgement time, end time, etc.
S121, judging whether alarm information data of each monitoring variable belongs to key alarm or not according to a preset judgment rule; the preset judgment rule comprises a preset condition; the preset conditions comprise that SIL rating of related monitoring variables of the interlocking loop is larger than SIL0, and/or risk level in HAZOP analysis report is larger than 3;
in practical application, the types and the number of monitoring variables related to the DCS are numerous, and the influence weights of different monitoring variables on the judgment of the current working condition risk of the refining device are different, namely, some monitoring variables have higher weights, and some monitoring variables have little influence on the current working condition risk level of the refining device; therefore, in the embodiment of the invention, the alarm information data of each monitoring variable is correspondingly judged to determine the key alarm which has larger influence on the current working condition risk level of the refining device.
The preset judgment rule in the embodiment of the invention can comprise some preset conditions for screening, so that the alarm information data corresponding to the monitoring variables meeting the corresponding conditions are determined as key alarms; specifically, the preset condition may be that the SIL rating of the monitored variable associated with the interlock loop is greater than SIL0, and/or the risk level in the HAZOP analysis report is greater than 3; in addition, other preset conditions may be included in the determination rule according to experience or knowledge of those skilled in the art.
S122, grouping the monitoring variables by taking the workshop sections and the equipment as units; and according to all the monitoring variables corresponding to each workshop section or equipment, constructing an alarm information record set of each workshop section or equipment;
in the prior art, alarm information data of each monitoring variable are independent and cannot reflect the incidence relation among a plurality of monitoring variables on each work section or equipment, and the inventor finds that the work condition risk in the refining plant is often in units of work sections or equipment, namely, before an accident or a fault occurs in a certain work section or equipment or when the accident or the fault occurs, certain statistical characteristics of the alarm information data of a plurality of monitoring variables of the work section or equipment can reflect the work condition risk. Determining the number of centralized monitoring variables of alarm information records of a workshop section or equipment by registering each monitoring variable of the workshop section or the equipment; therefore, each alarm information record generated in real time can have a corresponding relation with the workshop section or equipment to which the alarm information record belongs, and further, the corresponding statistical calculation can be conveniently carried out on the alarm information record of each workshop section or equipment generated in real time.
In the embodiment of the present invention, the statistical characteristics of the alarm information data capable of reflecting the working condition risk of the working section or the equipment include: when the alarm information records of a certain working section or equipment are centralized, if the number of alarms is too large or the alarm duration is too long, the working condition risk of the working section or equipment is too high, and a warning needs to be sent out by generating a working condition risk result; in addition, when the proportion of a critical alarm in a certain workshop section or equipment is too high, the workshop section or equipment has too high working condition risk, and a warning needs to be sent by generating a working condition risk result.
S13, determining a working condition risk result of the refining device according to a preset algorithm by taking the alarm information record as a parameter; the preset algorithm comprises the following steps: setting a quantity threshold value for generating the alarm information records in a preset time length, and/or setting a duration threshold value for generating the alarm information records in the preset time length.
Based on the statistical characteristics of the alarm information data capable of reflecting the working condition risks of the working sections or the equipment, the preset algorithm in the embodiment of the invention may include:
setting a quantity threshold value of corresponding alarm information records in a preset time length for each work section or equipment, and generating corresponding working condition risk warning to prompt that the work section or equipment needs to be subjected to working condition risk control after the alarm quantity of a certain work section or equipment exceeds the quantity threshold value corresponding to the work section or equipment;
setting a duration time threshold of alarm of corresponding alarm information record in a preset duration for each work section or equipment, and generating corresponding working condition risk warning to prompt that the work section or equipment needs to be subjected to working condition risk control after the alarm quantity of a certain work section or equipment exceeds the duration time threshold corresponding to the work section or equipment;
in addition, in the embodiment of the invention, the proportion threshold of the key alarm in the corresponding alarm information record is set for each workshop section or equipment, and when the proportion threshold of the key alarm of a certain workshop section or equipment exceeds a preset value, a corresponding working condition risk warning is generated to prompt that the workshop section or equipment needs to be subjected to working condition risk control; therefore, the preset algorithm may further include a duty threshold for key alarms in the alarm information record set.
In summary, in the embodiment of the present invention, it is considered that the alarm information of a single monitoring variable can only provide an abnormal condition of one point, and the reason for generating the alarm information includes multiple situations with different risk levels, such as overrun alarm, deactivation, and instrument failure, and therefore, the alarm information of a single monitoring variable cannot accurately reflect the risk of the refining apparatus. Therefore, further, in the invention, monitoring variables can be grouped by taking the workshop sections and the equipment as units, so that the grouping of alarm information records is realized, and each workshop section and equipment correspond to a corresponding alarm information record set; then, the invention respectively obtains the working condition risk results of each workshop section and equipment by judging the key alarm proportion of the corresponding alarm information record set of each workshop section and equipment; therefore, the sensitivity of key alarm in alarm information recording is increased, potential safety hazards caused by possible neglect of key alarm (namely important risk alarm) of operators can be avoided, and the accuracy and effectiveness of the refinery device operation risk early warning are further improved.
