The control system of UAV flight control center power supply

The report examines the construction of the UAV flight control center power supply control system, which provides continuous operation of the center and minimizes the failure of center's expensive equipment.

The reliability of the smooth operation of the UAV flight control center directly depends on the configuration, composition and performance of the electricity system. In this regard, the power system can be compared with the system of climate maintaining, the proper functioning of which influences the continuity of the provision of related systems services. In addition, the climate and electro supply systems stand out among other engineering systems of the equipment by the level of complexity, the mutual influence of the individual subsystems and their components at each other. UAV flight control center power supply is classified in the international standard TIA-942 to the third and fourth level of reliability. Therefore, to achieve this level is necessary to ensure the smooth and / or secured power supply of a number of engineering systems. The power supply system must protect sensitive to input power network characteristics computers' power supply units from transients appearing due to the automatic distribution of the load between the primary and backup switching elements or as a result of the crash in one of the consumers of engineering systems. In addition, in the electrical system should be implemented the ability to transfer the load from the main equipment to the reserved and forth without any power surges. This problem is solved by a power supply control system.

In general, UAV flight control center power supply consists of:

-General power supply system;

-Uninterruptible power supply systems;

-Systems of guaranteed power supply;

-Supply, distribution and group networks;

-Grounding systems.

To ensure reliable operation of the control system of UAV flight control center power supply we need to have a control system, which should perform the following functions:

-Maintaining continuous control of the mains parameters (current, voltage, etc.) with data saving in case of emergency for subsequent analysis;

continuous monitoring of the switching devices position;

-Detection of emergency and pre-emergency situations in the supply and distribution networks by the output values ​​of monitored parameters exceeding the limits (dips and spikes, blackouts, high voltage spikes, noise, impulse noise, the deviations of frequency);

-Detection of emergency and pre-emergency situations and failures of equipment by change of position of switching and protection devices;

The automatic switching to a backup or stand-alone power supply in case of powered down or failure of the main power supply;

Remote-control of switching devices;

-Switching of electrical loads (electric drive, contactors) by dispetcher's command or by temporary program

Control of object's lighting system to the level of distribution boards;

-Control of exterior lighting, advertising lighting with photocell and magnetic starters state monitoring, providing arbitrary delays by switching on and off by the state of light sensors;

-Smooth adjustment of lighting depending on the time of day, the weather, the presence of people in the room;

-Lighting modes (Night, standby, emergency, workers, presence simulation);

-Issuance of an alarm in the control room.

Such system is based on the operational and information management systems.Modern hardware and technical base of all levels of the system is a solid foundation of the complex.

The flexibility of the system is achieved by using hardware and software solutions to expand the range of tasks and functions of the hardware and software components of the complex.

The scalability of the complex is achieved by cascading of systems, when the upper level of the subsystem is the next lower level of the hierarchy.

The modularity of systems and ability of components to work offline allows you to build exactly to the task system with maximum use of its resources.

Fig. 1 shows the structure of the control system of UAV flight control center power supply, which has all the above features.

On the lower level of the system as a basis for the integration of the equipment used by industrial PCs, PLCs, relay protection and automation - RZA. The basis for the construction of this level are microprocessor-based relay protection, automation, control and management of MRSA-05 connections of SE PA "Kievpribor." Combined to remote data collection stations and controlled remotely controlled items.

At the level of the collection and storage of data to ensure the required reliability data storage system as a hardware data collection stations, the central servers are used. Software station operates under the operating system Windows Server.

At the top level of the system are workstations (AWS) based on industrial computers and visual display (displays, mnemoshields, video walls, etc.).The main workstations:

- ARM Remote Control (TM) - the collection and processing of TM data, control equipment, system administration.

- Workstation Manager (TM) - displays the status of objects in the form of TM operational schemes, conducting reference and reporting documentation, mathematical and statistical processing of the data.

Conclusions. The proposed control system power management center UAV enables reliable operation of the flight control center and minimizes failures of expensive equipment.
