Description

The invention relates to the field of operation, maintenance, operation monitoring, repair and creation of complex technical systems, in particular, to automated control systems for technological processes and service and repair resources of complex technical systems (STS), for example, in power equipment.

A well-known automated process control system for repairing complex technical systems using mobile repair and diagnostic systems (see RF patent No. 2420777, pr. 23.10.2008, publ. 27.04.2010, IPC G05B 15/00), containing the central computer of the system with in his memory, a database of reference data on serviced technical systems, a catalog database on the components of serviced technical systems, a database of spare property, materials and accessories (spare parts) as part of repair and diagnostic one set (RDK) and complexes serviced products; and a remote terminal of an automated workstation (ARM) for monitoring and diagnosing components of serviced systems, while before leaving RDK to conduct a specific type of work on a specific technical system, documents on the profile of this system are loaded into the database of the automated process control system (APCS), upon arrival at the place of deployment of the serviced technical system, the remote terminal is located at the place of work directly at the serviced component and products, and the remote terminal is equipped with measuring modules and modules for generating stimulating effects that are connected to the corresponding points of the controlled components of the serviced and repaired technical system, characterized in that it includes sets of automated workstations for managing technological operations for the repair of replaceable structural elements as part of the RDK, structurally combined with technological jobs by type of work as part of the technological percent The repair process, connected through the interface line to the central computer of the system with the formation of a common control system local area network, each set of the workstation contains a computer, a monitor, a barcode reader and a manipulator for interactive feedback of the repairman and the workstation computer, in A PCS central computer database introduced graphic images of structures of repaired component parts with the possibility of highlighting fragments of structures that are objects of repair actions, objects of repair, laying of spare parts, and technological tools are identified by the corresponding barcodes.

The disadvantages of the analogue are the insufficient effectiveness of information support for the actions of repair personnel due to the insufficient visibility of prompts for disassembling, repairing, assembling, and monitoring the performance of the STS and its midrange and the inefficiency of identifying the components of the STS and the technological equipment of the RC using barcode labels for the repair of STS Long service life. During long-term operation, barcode tags may be dirty, damaged and not suitable for reading the identification data of the MF of the serviced STS and the technological equipment of the RO used for maintenance and repair work. This reduces the efficiency of work, the effectiveness of information support for work (work management) from the ACS PR and leads to higher requirements for repair personnel.

The closest in technical essence is the repair management system of complex technical systems (US Pat. RF No. 2450304, IPC G05B 15/00, dated May 10, 2011, published May 10, 2012), consisting of a repair and diagnostic complex that contains a central computer and an automated workstation for managing technological operations, combined with a central computer using an interface line to a local area network. Automated workstations for managing technological operations are structurally combined with the corresponding technological workstations. When carrying out work, a remote terminal and an additional external automated workstation are connected to the repair and diagnostic complex during work. All automated workstations are equipped with radio frequency readers, which allow reading information from radio frequency identifiers installed on removable technological equipment and tools that are part of the repair and diagnostic complex. The central computer for process control is connected to the workstation by direct and feedback using control software. When performing a closed technological cycle of repairing the components of a complex technical system being serviced with the help of a manipulator included in the automated workstation, the operator of each technological workstation, in response to instructions on performing operations on the monitor screen of the automated workstation, implements feedback from the automated workplace to confirm completion given from the workstation of technological operations. The composition of the automated workplace and the technological workplace is determined by the type of work within the framework of a closed repair repair cycle implemented as part of an automated repair body. Each workstation includes RFID readers. Radio frequency identifiers are applied to each object of technological equipment, tools and property as part of the repair body. By displaying the corresponding automated workstation on the monitors screen, instructions are given to the operator of the technological workplace, including the type and location of the repair body, using the RFID reader, an accelerated search for the specified technological equipment required to perform the specified operation is performed and accelerated return of the used tool to a regular place in the repair body. When performing technological operations from a central computer, the image is transferred at an automated workstation where the objects of repair are visually displayed, the technological equipment (tools) used, as well as the sequence of technological operations of maintenance and repair of a complex technical system.

A disadvantage of the known technical solution is the insufficient functionality of the process and resource management system of complex technical systems.

This system is intended only for technological operations associated with the repair of a complex technical system, which is insufficient for a comprehensive solution of all the required tasks to ensure a safety system when working on power equipment.

The system operates only within the repair and diagnostic complex, which is conditionally mobile. This system cannot be divided into components and spaced them at a distance greater than the remote information channel of the system. Accordingly, this analogue is not suitable for distributed technological work at objects spaced over long distances.

The control software of the closest analogue is not suitable for processing information on work and generating reports on various criteria of work carried out on power equipment.

The objective of the proposed technical solution is to develop a security system and control of work on complex technical circuits, for example, power equipment, increased security, information content and ease of use.

The technical result of the proposed technical solution is to expand the functionality of the control systems for repair, maintenance, creation and operation of complex technical systems (STS).

The technical result is achieved due to the fact that in a comprehensive security system and work control on complex technical systems, containing a central processor connected to each other to ensure control of technological processes, a portable processor, while the processors are equipped with monitors, radio frequency identifiers installed on the controlled objects, and RFID readers, capable of transmitting data to processors, central process Op for process control is linked with a portable processor and direct feedback in radio frequency identifiers previously entered identification controlled object,

introduced a mobile reader of identification data from radio frequency identifiers associated with a portable processor, while an identification data reader and a portable processor are rigidly fixed relative to each other with the formation of a mobile hardware complex, which is equipped with audio-visual fixation with the ability to output recorded information to the processor monitors, the central processor is connected with a portable processor via a digital communication channel, radio frequency identifier mounted on the fixed and mobile controlled objects, stationary readers identification data are installed in the locations of stationary objects under control to ensure constant monitoring of the state of the object.

Radio frequency identifiers are fixed on stationary equipment, tools, personnel clothing, vehicles.

The mobile hardware complex is equipped with global navigation positioning.

The central processor is additionally designed to provide external information systems containing background information on equipment, on technological processes and internal information processes of the company.

The introduction of a mobile reader of identification data from radio frequency identifiers, rigidly connected with a portable processor, forming a mobile hardware complex (IAC), which is equipped with audiovisual fixation and location tools with the ability to output recorded information to processor monitors, provides comprehensive information support for technological operations. On the screen of the mobile hardware complex an object is displayed on which to perform an operation, the tool used and the nature of the actions to perform a given technological operation can reduce the qualification requirements of personnel involved in carrying out work on complex technical systems, such as power equipment.

The creation of a single database of the entire array of information received from the mobile hardware complex during the execution of work allows to increase the effectiveness of control over work on complex technical systems, such as power equipment, and to provide the ability to control the actions of personnel, due to the use of movement and location monitoring tools personnel, which increases the safety of work.

The use of digital communication channels, differing both in the medium of data transfer and in the types of protocols, between the central processor and the mobile hardware complex (IAC) instead of communication via the interface bus will increase the efficiency of information exchange, reliability of information transfer, and increase service mobility.

The presence of digital channels and software modules that are part of the control software of the central processor ensures interaction with external information systems, which increases the information content of the system and, consequently, the safety of the work performed.

Due to the use of a strictly prescribed sequence of technological operations in electronic forms, the possibility of erroneous operation of equipment of a technological object, for example, an energy object, is eliminated.

The installation of radio frequency identifiers on all controlled equipment allows you to control a wide range of technological operations on the equipment, such as manipulating the equipment, preparing the workplace and access to work, inspecting the equipment.

The introduction of global navigation positioning tools into the mobile hardware complex, for example, the GPS or GLONASS module, makes it possible to monitor the movement of personnel between objects and objects that have a large territory, when the size of the territory does not allow a reliable exchange of information between readers and tags , which increases the information content.

The ability to connect to external information systems, which contain reference information on the equipment and internal processes of the company, provides additional functionality when generating reports on the work performed, and also provides the most complete integration of the system into the electronic document management systems already existing at the enterprise.

The installation of additional stationary readers of radio frequency identifiers along the perimeter of the room and on the equipment parts and marking of the radio frequency identifiers of the overalls of personnel and vehicles allows controlling the movement of personnel, equipment, vehicles inside objects of a technological system, for example, an energy system, increasing the safety of work.

The drawing shows a diagram of an integrated security system and control of work on complex technical systems.

The automated integrated system includes:

1 - central processing unit;

2 - stationary processor of a workstation;

3 - wire and digital communication channels;

4 - mobile hardware complex (IAC);

5 - tablet processor;

6 - mobile reader of the radio frequency identifier;

7 - radio frequency identifier;

8 - stationary radio frequency reader.

The system contains a central processor 1, which is the core of the system. It runs management software, all current and archived databases are located. With the central processor 1, through wired or wireless digital communication channels 3, to exchange information, communicate: mobile hardware complex 4, stationary processor 2. Also, through digital communication channels 3, the central processor 1, communicates with external information systems. The mobile hardware complex 4 consists of a tablet processor 5 and a mobile reader of the radio frequency identifier 6, which is designed to write and read information from the radio frequency identifier 7. A stationary reader of the radio frequency identifier 8 is connected to the stationary processor 2, for reading information from the radio frequency identifier 7.

When performing technological operations, for example, on power equipment, such as operational switching, equipment inspections, workplace preparation, personnel use a mobile hardware complex 4.

On the mobile hardware complex 4, for each specific type of operation, the corresponding electronic form is launched for execution. An electronic form is a pre-recorded sequence of technological operations that must be performed on equipment. Depending on the type of work of the electronic form, there are several types:

- electronic switching form;

- electronic equipment inspection form;

- An electronic form for preparing a workplace for work.

Electronic forms are contained in the database of the central processor 1. Their creation and editing is carried out from a stationary computer by means of control software operating on a stationary processor 2, and control software operating on a central processor 1. A typical electronic form is created before starting work on the equipment , must be loaded into the memory of the mobile hardware complex 4. Several methods are possible:

1) from the central processor 1, through digital communication channels 3, to the mobile hardware complex 4, a typical electronic form is loaded to perform a specific technological operation;

2) using the built-in software 4 in the mobile hardware complex, you can create a new switching form. An electronic form created in this operating mode must be approved in advance. For this, the mobile hardware complex 4, using digital communication channels 3, is connected to the central processor 1, where, using the control software, the form is registered and a request for approval is sent to the stationary processor 2, which is located at the personnel authorized to approve the electronic form. If the mobile hardware complex 4 is outside the coverage area of digital communication channels 3, personnel performing technological operations are vested with the rights of independent approval of the electronic form. To implement the various operating modes of the mobile hardware complex 4, the function of delimiting access rights is implemented in its control software.

An integrated security system and control of work on complex technical systems works as follows.

Upon arrival of the personnel to the place of work, on the mobile hardware complex 4, the electronic form is launched. In accordance with the sequence of technological operations, the screen of the mobile hardware complex 4 displays the name of the required operation, a description of it and information about the location of the equipment at the power facility over which the operation is performed. The personnel performing the work to fulfill the item of the electronic form, using the mobile reader of the radio-frequency identifier 6, which is part of the mobile hardware complex 4, and the radio-frequency identifiers 7 installed on the equipment, identifies the equipment. If the equipment is correctly identified, the service information is recorded on the identifier of the last read date, the type of work being carried out, and the particular contractor who performed the work. After identification of the equipment, visual and sound confirmation takes place, and the staff performs the necessary technological operations, in accordance with the description of this item in the electronic form. Upon the execution of operations, the staff confirms the operation, after which the control software of the mobile hardware complex 4 makes the transition to the next paragraph of the electronic form.

In the event that an emergency occurs during the performance of work or additional information is required from the dispatcher, personnel can suspend the electronic form and contact the dispatcher via digital communication channels 3. To do this, on the mobile hardware complex 4 there are means for audiovisual interaction, such as a microphone and a video camera.

When monitoring the technical condition of equipment at technological facilities, such as power facilities, an electronic equipment inspection form is loaded into the mobile hardware complex 4, which regulates the sequence of actions of personnel during work. For each item on the electronic form, information is given on the name of the equipment, its location at the facility, and the values of the monitored parameters of the equipment being inspected. The staff identifies the equipment using a mobile reader of the radio frequency identifier 6, which is part of the mobile hardware complex 4, and the radio frequency identifier 7 installed on the equipment. After identifying the equipment, the staff inspects the equipment and enters the mobile hardware complex 4, using the means of manual input of information, the values of the monitored parameters. If during the operation a photo-video recording of the equipment status is required, then using the video camera integrated in the mobile hardware complex 4, this shooting is performed and the recorded file is assigned to this item of the electronic form. After completion of the current operation, a confirmation of completion is entered into the mobile hardware complex 4, and the control software of the mobile hardware complex 4 is transferred to the next paragraph of the electronic form.

After completion of all technological operations included in the electronic form, the procedure for closing the form is formed. The personnel performing work on power equipment confirms the completion of work on the mobile hardware complex 4 by entering an individual digital signature.

The status of the form is marked as “Completed”, all information on the mobile hardware complex 4, obtained in the process of performing technological operations, is archived and transmitted via digital communication channels 3 to the central processor 1. If the mobile hardware complex 4 is outside the range of the digital communication channels 3, sending information does not occur. The repeated procedure for transmitting archive information is performed after the mobile hardware complex 4 is in the coverage area of digital communication channels 3.

The entire tool used by personnel when working on power equipment is equipped with radio frequency identifiers 7. In carrying out specific technological operations that require the use of a tool, personnel, in accordance with a request for electronic form, use a mobile reader of radio frequency identifier 6 connected to mobile hardware complex 4 to produce reading information from a tag. After the successful identification of the tool, the electronic form executed on the mobile hardware complex 4 goes to the point where the personnel must perform the technological operation using this tool. When this item is executed, the reverse timing of the operation is started. If the operation was not performed after a specified time, the control software of the mobile hardware complex 4, in accordance with the information in the electronic form, returns to the item identification tool.

During the execution of any electronic form on the mobile hardware complex 4, the audio / video fixation is automatically started, which stops after the personnel confirm the completion of work. Received audio / video recordings, along with the rest of the information received during the execution of the electronic form, are sent to the central processor 1.

Geographic tools, for example, the GPS-GLONASS module, are designed to determine the location of personnel and record the route of personnel movements during work on power equipment in the mobile hardware complex 4. If the mobile hardware complex 4 is located in the coverage area of digital communication channels 3, it is possible to directly control the movement of personnel from any computer connected to the central processor 1 through digital communication channels 3. For this, it is necessary to indicate in the control software installed on the computer the identifier of the mobile hardware complex 4, the movements of which must be controlled, and its current position, superimposed on the map of the area and premises, will be displayed on the screen.

Information is entered into the memory of the central computer that displays the position of the corresponding component of the complex technical system at the facility and the sequence of technological operations and the tools used in each technological operation in the sequence of technological processes when performing work on a complex technical system, and before starting work on complex technical system digital information on technological operations under the control of a central mpyutera transferred from the central computer memory in the computer's memory a workstation, the operator workstation, in response to an indication of the procedures on the screen workstation implements feedback portable workstation to a central computer.

The control software operating on the central processor 1, through digital communication channels, provides the exchange of information with the mobile hardware complex 4 stationary processors 2 and external information systems. Based on the information received, on the central processor 1, a database is formed to perform technological operations on the equipment and the condition of the equipment itself. The receipt of information from the database of the central processor 1 in the form of reports is based on requests received from the stationary processors 2. The order of access to the information of the central processor 1 is regulated by the system of differentiation of rights.

Functioning control software on the central processor allows you to perform the entire scope of tasks related to the functioning of an integrated security system during work, for example, on power equipment, including processing and archiving all received information about ongoing technological operations on equipment and personnel transfer, generating reports on the work performed and the issuance of the required information on given requests, interaction with external systems of the enterprise, which uses An automated system for controlling technological processes and monitoring objects on complex technical systems.
