Method and application of the method for providing a data processing arrangement for condition monitoring of electronically monitored installations

The present invention is in the technical field of condition monitoring electronically monitored systems and relates in particular to a method and its application for the provision of a data processing arrangement for condition monitoring electronically monitored systems.

To monitor the status of electronically monitored equipment such as disconnectors, circuit breakers or transformers during operation, systems are used to collect and evaluate data about the condition of the electronically monitored equipment. The data may be measurement data such as electrical measurements or temperatures, pressures, etc., but may also include maintenance information or the like. In order to be able to centrally evaluate a large number of different electronically monitored systems, systems must be used that can record and evaluate different data in different data formats. Siemens AG's SIPLUS CMS4000 X-Tools User Manual Release 2011-02 (page 21) recognizes the X-Tools software, which is installed on a central data processing system and receives and displays measurement data from a large number of different SIMATIC control devices. An experienced technician can, after installation and configuration of the software, make measurements on the state of connected electronically monitored equipment. The experienced technician can use his expert knowledge to decide which actions, such as alarms or planned maintenance work, are required.

It is the object of the invention to provide a method for providing a data processing arrangement for a state machine. To provide monitoring electronically monitored systems, in particular to provide a method that is easily adaptable to different electronically monitored systems. The invention achieves this object by a method for providing a data processing arrangement for condition monitoring of electronically monitored installations with a data storage arrangement, in which rules are respectively defined in the data storage arrangement in at least one calculation rule file for the calculation of output data from input data, and in at least one definition file Input channels for the input data and output channels for the output data are specified, and in a customization file for each electronically monitored system references to the specific input channels and specific output channels in the definition file that can be assigned to the respective electronically monitored system and references to the specific input channels and specific output channels corresponding rules are generated in the calculation specification file, and in at least one condition monitoring file a date n structure is provided to provide output data for each electronically monitored system using the adjustment file based on the rules from input data.

Under a data processing arrangement according to the invention, for example, a computer or a part of a computer network is understood; however, it may also be a network consisting of spatially separated data processing devices, the parts of which are connected via data links, such as internet connections. Another example is a cloud that can be used as a data processing device. Accordingly, the data storage arrangement may comprise a single data store in which all files are stored centrally. However, the data storage device may also include several over a network such as the Internet connected data stores that are spatially separated. This allows the data used to be stored in different locations in different data stores. Another example is cloud-based data storage facilities.

Any combination of output data and input data can be defined in the rules of the calculation rule file. In particular in connection with electronically monitored systems, it is advantageous to store general expert knowledge of electronically monitored equipment in the form of machine-translatable formulas, comparisons or instructions. The expert knowledge includes, for example, the maximum and the minimum operating temperature, the maximum and the minimum outside temperature, the date of the next scheduled maintenance and the like.

The definition file contains general information about the input and output channels. This achieves an adaptation to different data formats as well as communication protocols and types such as powerline communication, Internet connections and the like. This is advantageous because the method can be easily adapted to different electronically monitored systems with correspondingly different input and output channels.

Input data in the sense of the invention are, for example, signals by means of a "Supervisory Control and Data

Acquisition (SCADA) "System transmitted data about the state of a disconnector, such as a signal about opening and / or closing the disconnector, or an error message.

Output data in the sense of the invention are, for example, system state data such as information on the current or future estimated functionality of the electronically monitored system, the period since the last Maintenance of the system to be electronically monitored, the number of alarms since the last warning or similar.

The modular acquisition of information in the at least one calculation rule file and the at least one definition file achieves a strict separation between the acquisition of expert knowledge and knowledge of the condition of the connected equipment. This is advantageous because thus both kinds of knowledge in the respective file can be changed separately, which simplifies the adaptation by a technician.

By using a customization file for each electrical equipment to be monitored, it is easy to select and apply, from the general knowledge stored in the definition file and the calculation rule file, the knowledge needed for the condition monitoring of a particular installation. This is advantageous because in a particularly simple manner by a technician, a new installed system can be monitored for their condition.

By means of the condition monitoring file, it is achieved that all information required for condition monitoring of an electronically monitored installation is centrally summarized information about input channels, output channels and condition monitoring rules. This is advantageous because the condition monitoring file contains the expert knowledge for condition monitoring of a specific electronically monitored installation in a simple, clear and machine-implementable manner.

A further advantage of the invention is that even technicians with comparatively less experience can successfully perform condition monitoring through the automated application of expert knowledge.

In a preferred embodiment of the method according to the invention, the electronically monitored installations comprise electrical installations, in particular electrical installations of a power grid. This is advantageous because electrical systems, such as disconnectors or circuit breakers, often have different production times and manufacturers in a given energy network, so that the data transmitted by them is present, for example, in different data formats. The inventive method makes it possible to automatically monitor such different systems centrally and to include in a particularly simple way new in the energy grid added electrical installations in the monitoring.

In another preferred embodiment of the method according to the invention, a table is generated in the at least one state monitoring file with one line for each input channel and / or output channel defined in the definition file. This is advantageous because a variety of different input and output channels depending on the type of electronically monitored systems is used.

In a development of the abovementioned embodiment of the method according to the invention, a column is generated in the table for each reference to a rule defined in the adaptation file. This is advantageous because it allows an easy way of monitoring many different electronically monitored installations via the input channels with the same expert knowledge defined in the rules. It is also possible to use a table in which columns and rows are reversed: in such cases, the columns contain information about input and output channels.

In a further preferred embodiment of the method according to the invention, the at least one calculation template file is generated from a calculation rule file template by means of querying expert knowledge. This offers the advantage that the expert knowledge available, for example, in external databases or by a user about the status monitoring can be stored in electronically controlled systems in a machine-convertible form in the calculation rule file. In a preferred embodiment of the abovementioned embodiment of the method according to the invention, status information and / or triggering information and / or additional information are requested as expert knowledge. This is advantageous because in this way a variety of different types of information can be queried and stored clearly separated. This clear separation makes it easier to recognize in a later change of the stored information in which area the change should be made.

In another preferred embodiment of the method according to the invention, measurement data and / or authorization results are used as status information. This is advantageous because it allows e.g. the data collected by sensors in the electronically monitored equipment can be evaluated.

In a further preferred embodiment of the method according to the invention, alarms and events are used as triggering information. This is advantageous because alarms and events allow an experienced technician and / or operators of the electronically-monitored equipment to immediately detect and initiate appropriate actions in the operation of the electronically-monitored equipment. Such actions may include, for example, the emergency shutdown of an electronically monitored system or its maintenance.

In a development of the abovementioned embodiment of the method according to the invention, stages of the Integrated Substation Condition Monitoring (ISCM) standard are used for the events. This is an advantage because the ISCM standard provides the user with easy to understand events as triggers. be defined, which makes it even easier to immediately initiate the necessary actions.

In another preferred embodiment of the method according to the invention, as additional information, parameters for calculations and / or internal variables with intermediate storage of intermediate results are used. This is advantageous because, as additional information, a multiplicity of further components of the expert knowledge can be detected and thus an even better adaptation of the method for providing a data processing arrangement to the respective conditions of the electronically monitored systems to be monitored is made possible. In a further preferred embodiment of the method according to the invention, it is determined for each of the status information and / or triggering information and / or the additional information whether the respective information is measurement data, a calculation result, an alarm, a parameter or an event. This definition is advantageous because the clear classification of the information stored as expert knowledge makes it easier to store the expert knowledge in a machine-implementable manner and to update the corresponding stored expert knowledge later, for example when introducing a new generation of equipment.

In a further preferred embodiment of the method according to the invention, it is determined for each status information and / or triggering information and / or additional information whether the respective information is input data and / or output data. This definition is advantageous because the clear assignment of input data and output data is a prerequisite for machine-implementable storage of the expert knowledge.

In a further preferred embodiment of the method according to the invention, data records with properties for types are electronically monitored in an instance database Plants filed. This is advantageous because, for example, for a particular type of electrical system in an energy supply system, the expert knowledge for this type of plant is stored and does not need to be re-recorded for each specific system.

In a development of the abovementioned embodiment of the method according to the invention, a supplementary instance file for each electrical system is generated in the instance database from a data set with properties of one type of electronically monitored systems by means of a supplementary adaptation file. This means that from the general expert knowledge stored in the instance database about the properties of one type of electronically monitored equipment, it is easy to create subtypes or special files with the properties of individual electronically monitored equipment to be monitored. This type of hierarchical storage and processing of information is called object-oriented programming in the field of data processing methods and is advantageous here because the definition of general objects or data records with properties of the types of electronically monitored systems requires that these data be stored only once. Thus, storage space is saved. It also makes it easier to add supplemental instance files to newly added electronically-monitored assets because not all of the required data has to be recaptured.

In a further preferred embodiment of the method according to the invention, input data are received into the input channels (11, 12) by means of different communication protocols and / or from different electronically monitored systems and output data from the output channels (12, 13) by means of different communication protocols and / or to different ones Evaluation facilities transmitted. This is particularly advantageous because data from a variety of electronically monitored systems can be merged and evaluated in the simplest way. WEI terhin, it is advantageous that the evaluated data can be transmitted via a variety of different output channels to corresponding evaluation devices. This facilitates the centralized processing and monitoring of the condition of numerous electronically monitored installations, for example in a widely branched power grid.

In another preferred embodiment of the method according to the invention, XML files are used as adaptation files and stored in the data storage arrangement. This is advantageous because XML files represent a widely used file format and saving the files in the data storage arrangement makes it possible to preserve the already made settings in the customization files even when the data processing device crashes and to retrieve them when the system is rebooted.

Another object of the present invention is to apply the method provided.

The invention solves this problem by providing an application to a data processing arrangement provided according to the method of any one of the preceding claims, wherein a data storage access device in a data processing area of the data processing device applies the rules to the input data received from the electronically monitored facilities and provides output data provides. This application of the method according to the invention is advantageous because a particularly simple and clear condition monitoring is made possible by the use of the expert knowledge provided for in the method according to the invention for the condition monitoring of the respective electronically monitored installations; In particular, the user (eg a technician) requires comparatively less expert knowledge in order to draw conclusions from the data provided to necessary actions. In a preferred embodiment of the application according to the invention, an evaluation device evaluates on the basis of the output data whether an action signal is output. The use of the evaluation device is advantageous because the evaluation device provides the user with a particularly clear decision-making aid in the form of action signals for the output data calculated by the rules in the data structure, which characterize the electronically monitored systems to be monitored. An action signal may be, for example, a warning on a display device, which advises an immediate shutdown of an electrical system. In a further preferred embodiment of the application according to the invention, at least one "supervisory control and data acquisition (SCADA)" system and / or a database and / or a web server are used as evaluation devices, which is advantageous because the evaluation devices mentioned are widespread technical examples of In another preferred embodiment of the application according to the invention, the data memory access device makes the output data available again after the creation of a supplementary instance file a new instance of the generally defined electronically monitored system now another electronically monitored system can be monitored for their condition.

In a further preferred embodiment of the inventive application, the production is complementary

Instance files during operation of the application of the method. This is an advantage, because thus also during the current condition monitoring of a plurality of electronically monitoring systems in addition to another monitored electronically monitored system during operation, the condition monitoring of the new system can be included. Therefore, it is not necessary to cancel the current state monitoring and resume after appropriate configuration of a new system, which increases the reliability and saves costs.

Furthermore, the subject matter of the present invention relates to a computer program for the application of the method according to one of the preceding claims. This is an advantage because in a computer program the individual process steps can be stored in machine-convertible form. Furthermore, a storage medium with the aforementioned computer program is also part of the subject of the invention.

An embodiment of the application of the method according to the invention is shown in FIG.

The data processing arrangement 1 for condition monitoring of one or more electronically monitored installations (not shown) comprises in a conventional computer system 2 a data storage arrangement 3, which may be for example a main memory or a hard disk. Furthermore, the data processing arrangement 1 comprises a data processing area 4. The data processing area 4 is e.g. a processor unit that can perform calculations. Furthermore, there is an instance database 30 in which

Data records with properties for types of electronically monitored installations 31 are stored. In the instance database 30, supplementary instance files 32 to 34 generated by means of a supplementary adaptation file are stored for each electronically monitored installation from a data record with properties of one type of electronically monitored equipment 31. Within the data processing device 2 is in the data storage device 3, a calculation rule file 5 with Rules 6 to 9 are stored for the calculation of output data for input data. The rules contain expert knowledge about condition monitoring of electronically monitored equipment. Output and input data are not shown explicitly in FIG.

Furthermore, a definition file 10 is determined which input channels 11, 12 are used for input data and output channels 13, 14 for the output data. Input and output channels are not shown explicitly. The input and output channels may be corresponding channels having different data formats or different communication links. In each case an adaptation file 15 for each system to be monitored electronically, references 16 to 19 to the specific input channels 11, 12 assignable to the respective electronically monitored installation and specific output channels 13, 14 in the definition file 10 as well as references 16 to 19 to the specific input channels 11 , 12 and specific output channels 13, 14 corresponding rules 6 to 9 created in the calculation rule file 5. The adaptation file 15 thus includes all the required information in machine-implementable form. For example, it is defined in the adaptation file 15 that a monitored electrical installation (not shown), such as a disconnector, supplies as input data temperature values of a temperature sensor to the data processing arrangement 1 via a so-called power line communication input channel. The temperature values in degrees Celsius are indicated by a temperature sensor. For example, a rule stipulates that a temperature value in degrees Celsius be converted into a temperature value in Kelvin and provided as output data. The output channel for the output data is an Internet connection in the example.

In the data memory 3, a condition monitoring file 50 is provided, which provides a data structure for condition monitoring. To generate the condition monitoring file 50 the adaptation file 15 is evaluated such that in the condition monitoring file 50 a table with a line 51 to 54 is generated for each input channel and output channel defined in the definition file 10. The columns of the tables 61 to 63 are generated for each reference to a rule 6 to 9 specified in the adaptation file 15. This results in a table in which fields 61 to 63, for example, three electrical installations or instances 32 to 34 are provided. In lines 51 to 54, for example, in line 51, the said conversion from degrees Celsius to Kelvin can be made, while in the remaining lines other input data can be converted to other output data. In the application of the data processing arrangement 1, a data storage access device 20 is used, which applies in the data processing area 4 the said rules 6 to 9 to the input data generated by the electronically monitored installations and thus makes the output data available.

The data storage access device 20 writes the output data into the individual fields of the table. These output data are available to an evaluation device 21 in the data processing area 4, which evaluates whether an action signal is to be output. The action signal is e.g. a specific action instruction for a user of the data processing arrangement 1. An action signal can be, for example, a warning or a request for the emergency shutdown of the state-monitored installations.
