Automatic Functions

The functions performed by acs include the information and control. For information functions include: – measuring (input, calculation) and analysis of the values of measured parameters and indicators of technological equipment – to display and register values of measured parameters and indicators of technological equipment; – detection, alarm, display and prompt registration of deviations of measured parameters, technological conditions and indicators of process equipment – the accumulation and storage of information about running processes and maintenance history of the process and product – Documentation current and consolidated information in the form of records and reports. Operative-technological information technology systems is the operator on the operator panel in a color graphic form (mimic trends in real time histograms, etc.) and alphanumeric form (in the form of messages). Warning and alarm is provided by the inclusion of an audio signal and a change in sign of the corresponding informational messages or mnemosimvola (eg, color change, background, flashing, etc.) to control functions include: – Automatic control of process parameters – program-logic control; – operation of locks and protection – manual remote control. Functional structure of acs depends on the amount of their functions, composition of the object management and location of its parts. The structure of acs is the principle of distributed control, according to which management tasks are divided between the programmable controllers, each of which serves a relatively self-object or group centered autonomous objects. Operational management and reporting is centralized in the dispatch room Control room. Configure controllers and control computers by engineers trc and the change in formulations together with technology of personal computers from the premises Engeneering room.

At the lower level (PLCs) perform functions that are directly related to the object of control: automated data collection and processing of measured parameters and status of equipment, automatic control parameters program-logic control, process blocking and defense. The composition functions of the lower level also includes a manual remote control of actuators, reserving control functions in case of failure of technical means of the upper level, as well as necessary during the commissioning and maintenance work. The structure features a top-level (personal computers) include operational management, centralized reporting of state technological systems. Configuration data, historical data, data provenance () product stored at the appropriate server stations in the server room (Server room). There is also a software software that performs a function with the level of plant management (ERP). Thus, the developed acs (to solve the problem of industrial automation thoughts of the object) on the structure are stacked multi-functional information management system.

To handle thicker sheets, and, if necessary, making several kinds of details appropriate to apply the bending machine with electric drive and opportunity to get a diverse profile. The most widely used bending equipment is harvested – locksmith operations: how in the manufacture of various boxes, covers, billboards and signage, additional elements and individual details, as well as directly in the production of stationary ventilation systems and roof pieces. In Russia, metal roofing has always been a sign of wealth and respectability. And that – not a fad: the climate here wet, a lot of days in the year are cold, often strong winds blow: Metal roofing has many advantages over wood or tile – high strength, resistance to ultraviolet radiation, and just a possibility, if necessary, easily be on the roof of his house. In addition, metal roofing lasts longer. We create for you the equipment that will allow you to make a variety of metal products and billets. Our bending equipment and bending machine (bending machine) will speed up your work and reduce the cost of manufacturing a variety of shapes and boxes of metal.

Detection And Elimination Of Forest Fires

In addition, the order of the state forest enterprises are obliged to fully control raise demands on companies, organizations, institutions and other businesses and individuals working or having different objects in forests, on the detection and elimination of its forces and means of fires occurring in their places of work or finding objects. In this work all these capabilities must be built so that every fire in area of forest fund could be detected at the beginning of his appearance, so that the message of the fire was immediately transmitted to the item, arrange fire and that the necessary forces and means of extinguishing timely return of the fire and ensured their elimination as soon as possible. Responsibility for the preparation and organization of all forces and means of detecting and extinguishing fires and for the timely liquidation of fires territories of forest enterprises responsible for forest owners and managers. Forest management authority in the Russian Federation will organize supervision of the owners of forest resources and forest managers to implement measures to ensure timely detection and fire suppression, and provide them with necessary assistance, bearing in mind that the forest fire protection is one of the most important state problems.

Motorized Adjusting

State power of Russia in recent years has improved, but lack of funding prevents the development of new technologies to improve the quality of the tpp, tpp and npp. Operation and development electricity sector is an important moment in the economy. Operation of energy facilities today is unthinkable without the use of technological schemes regulating valves. Flow Control working environment, its consumption in most cases is motorized gate valves. Response of the actuator to the changing processes or nonstandard (emergency) situation does not depend only on the valve and actuator, but also on the control command devices. At thermal and nuclear power plants in many cases necessary to use reverse contactors to control electric power up to 7,5 kW and above. When This flow chart of these devices, provides for work in the intermittent mode, with frequent launches.

The use of conventional electromagnetic actuators was not reliable here. Existing thyristor amplifiers or did not provide the necessary amount of power or do not have the necessary consumer protection functions of the electric overload on the shaft, breaking and phase imbalance, inrush current surge. An important requirement was the need to regulate the time of electrodynamic braking or turn it off. The presence of multiple electrical cables and electrical appliances, to impose similar devices Additional requirements for electromagnetic compatibility. Ensure maximum motorized actuator data functions and parameters is possible only with new circuit design and modern element base.
