Description

The technical solution relates to the field of means of collecting, accumulating and storing information and can be used in various fields of technology to manage information about controlled processes with increased requirements for the temporary coordination of information received.

An automated information system with time synchronization (AIS BC) can serve as the basis for building decision support systems and automated control systems (ACS).

Time synchronization is necessary for accurate timing and analysis of controlled processes. Temporal coordination is ensured by synchronizing the time scales of the AIS aircraft components and external interfaced systems and devices by introducing a time synchronization station (CER) into the AIS aircraft.

In general, the AIS aircraft solves the following tasks:

- input and storage of process execution plans;

- data collection and calculation of parameters of controlled processes;

- display of operational information about controlled processes and the dynamics of the implementation of plans;

- generation and archiving of reports on controlled processes and implementation of plan items;

- the formation of alarm notifications in the event that the controlled parameters exceed the permissible limits or the untimely completion of the plan items;

- synchronization of procedures within the framework of process control and implementation of plans;

- synchronization of time scales of the AIS aircraft components and external consumers;

- execution of countdowns for the current points of the plans.

As an analogue of the developed technical solution, an automated system can be used (RU, application 2000132776) for transmitting and receiving information on the state of controlled objects, containing primary measuring devices connected to client nodes, whose functions include collecting, pre-processing and storing information received from primary measuring devices, monitoring the integrity of communication lines with meters and the health of meters and transmitting information to input-output devices - or directly either, or through the corresponding information transfer nodes. An input-output device equipped with a computer accumulates, processes, and transfers information to its consumers, including to the system’s control and management unit via a radio channel, wire communication lines, or a telephone line through a modem. The control node (for example, a remote information collection point) manages the operation of the system as a whole, accumulates and analyzes the information received and / or presents the results to consumers of information. The registrars communicate with the input-output device via a wire line.

The main disadvantage of the known system should be recognized as the lack of the ability to synchronize data over time.

- information input devices;

- information output devices;

- data input / output modules;

- I / O expansion modules;

- extension modules for interfaces and protocols;

- mid-level control device;

- top level control device;

- time synchronization station.

The distribution of information management procedures across several levels (circuits) allows you to increase the speed and flexibility of the system.

The modularity of the scheme makes it easy to supplement and modify the existing system in accordance with the requirements arising in solving new problems, without stopping the system and altering its structure, limiting itself to the addition of hardware and software modules.

Data exchange in the system is organized through the information circuits of the lower, middle and upper levels.

The task of the lower level information circuits is to control the input and output of information. This level includes input and output devices, input / output modules, input / output expansion modules, and interface / protocol extension modules.

The middle-level information loop provides scheduling of data collection and management of information channels. The basis of these circuits are middle-level control devices.

The upper level of control (circuit) performs the orderly processing of information on the progress of the controlled process in various departments of the enterprise, provides quality management, and is also a real-time source of information for the highest level of decision-making.

Data transmission at all internal levels of the system and the level of interaction with external means can be performed in duplex, simplex or half duplex modes.

As input devices can be used, depending on the type of information:

- Measuring information input devices (analog and digital sensors, measuring devices, etc.);

- input devices for discrete information about the state of objects or processes (switches, buttons, relay contact groups, triggers, etc.);

- text input devices (keyboard, tablet, etc.);

- graphic information input devices (scanner, camera, graphic tablet, etc.);

- video input devices (video camera, webcam, video capture card, etc.);

- audio input devices (microphone, voice recorder, modem, etc.);

- pointing coordinate devices (joystick, trackball, graphic tablet, etc.).

Information can be entered without and with the participation of personnel in automatic, semi-automatic and manual modes.

The displayed information is divided into operational information and information for archiving.

Operational information displays the current characteristics and dynamics of the development of controlled processes, the correspondence of current processes to their implementation plans, the exact current time, duration and countdown time for the current plan items.

To output operational information can be used:

- data visualization tools (monitors, electronic display boards, projectors, light indicators, secondary clocks, etc.);

- acoustic devices (loudspeakers, headphones, etc.).

The output of information for archiving can be carried out using printing means, recording devices on magnetic and optical media.

Information input and output devices in various combinations can be combined in a management console to create automated workstations (AWP) for operators and system administrator.

I / O modules are designed for matching I / O circuits and pairing / converting data formats. I / O modules interact with a mid-level control device and information input and output devices.

External I / O modules are installed on remote sites, and they are connected to the top-level control device through communication channels.

I / O expansion modules are designed to increase the number of I / O modules connected to each information port of a mid-level control device. Thus, several serial channels can be connected to one serial port. I / O expansion modules contain at least one control device that performs the task of channel polling (multichannel switch), and are implemented on the basis of microcontrollers and programmable logic integrated circuits (FPGAs).

Extension modules for interfaces and protocols allow connecting devices that do not support the standard of the corresponding system port to the system. Interface and protocol expansion modules contain interface and protocol converters or network gateways and can interact with middle and upper level control devices, input / output modules, input and output devices. As an additional option for these modules, an I / O extension function can be implemented.

The mid-level control device is implemented on the basis of industrial controllers, namely built-in controllers or programmable logic controllers (PLCs) or industrial computers. To the control device of the middle level, devices of the lower information circuit can be connected. Control devices based on an industrial computer allow you to connect the operator’s console.

The top-level control device is based on an industrial computer. The middle-level control devices, input and output devices, external input / output modules, and an operator console can be connected to the control device of the upper level.

The AIS aircraft may additionally include equipment that solves communication problems: buffering and packetizing data, converting non-standard protocols, intermediate data conversion, channel multiplexing, etc.

The synchronization of information loops is provided by the time synchronization station, which is part of the aircraft AIS under consideration.

CER solves the following tasks:

- the formation, storage and display of the internal time scale; Correction of the CER internal time scale in relation to the UTC coordinated time scale;

- synchronization of the AIS aircraft information management circuits;

- providing information on the exact current time to all structural components of the AIS aircraft;

- issuance of synchronization signals to mating systems;

- issuing time signals in the formats “hours-minutes-seconds” and “day-month-year” on electronic display boards and / or secondary clock hands.

Correction of the internal time scale is carried out on the basis of the reception and processing of external reference signals of high accuracy - reference signals of frequency and time (ESCW).

The following signals can serve as an ESCW:

- formed on the basis of the national coordinated time scale of Russia UTC (SU) and transmitted via channels:
