2. PROJECT OVERVIEW
Human impact on the environment is boundless. Although we can’t abandon
dangerous industries, we can reduce the risks of man-made accidents to acceptable
minimum, and in many cases even prevent them.
In accordance with the Law On Environmental Protection in Ukraine, every hazardous
plant must have a plan of actions to minimize the threat of industrial emergencies by
automating the control of key production parameters and execution emergency
response plan in case of an accident. For this purpose the GTS hardware-software
complex was developed.

5. GTS SYSTEM OVERVIEW
GTS hardware-software complex consists of three main components.
1) Servers of GTS complex include:
• GTS Server – gathers information about the objects and execute actions
to contain the accident
• Weather Server – controls external weather station
• Log Server – records all operator actions, management nodes and
system events for further analysis
• Database Server – stores data that come from the server
2) GTS Client is the client interface used for:
• Monitoring the situation on the plant – Industrial Zone Workspace
• Displaying detailed information about each object beyond the plant –
Map Workspace.
• Displaying execution and providing users the opportunity to control the
process of the emergency response plan in case of an accident –
Emergency Response Actions Workspace
• Configuration of the GTS System
3) Industrial Zone includes: Management Nodes (MN), Executive
Mechanisms (EM) and Hubs (HUB), with attached Sensors (S) and Network.

6. GTS SERVER
GTS Server software is implemented with Finite state machine
technology.
GTS Server functions:
• Gathers information about potentially hazardous factors with the
help of sensors, connected with Management Node (MN)
• Forecast hazards based on data received from Sensors and data
stored in Database.
• If the accident occurs, it can generate a list of necessary actions
using data from the Weather Server.
• Performs actions according to emergency response plan with the
help of Executive Mechanisms, connected with the Management
Node (MN). In an emergency, it alerts the staff of the plant by
loudspeaker and calls to emergency services and nearby
municipal institutions.
• With the help of GTS client, it reports data to the operator,
receives commands from the operator, and if there is no response
from the operator, independently performs the set of actions.

7. GTS SERVER
The following cards are the components of the computer with GTS Server
installed:
• RS-485 Card is used for connection to the management nodes (MN)
located in the industrial area
• Voice Card is used to alert the workers at the plant by loudspeaker
(Voice Alarm System)
• PSTN Card is used for automatic notification via telephone lines about
an emergency situation beyond the enterprise
Expert system of GTS Serves assesses the situation at the plant and reveals the
threat of man-made disasters. Each time it assigns the current state of safety
level:
• Normal – all systems are working normally. Operator’s intervention is
not required.
• Test Alarm – this level of safety is assigned by the operator in manual
mode and is designed for a scheduled inspection of the system
• Increased Attention – set in case of failure of any node of the system
and requires a mandatory intervention.
• Accident – set under the threat of an accident or immediately on the
occurrence of emergency. Depending on the cause of the "Accident"
status, the system can work out a few different scripts.

8. GTS CLIENT
Management of the GTS complex is realized from the workplace of the
operator. For this purposes special software «GTS client» was
developed and implemented.
In GTS complex, the role-based access control model is applied. It
allows flexible share of the access rights to the nodes of the complex.
Currently, the following roles are realized:
• Observer
• Operator
• Administrator of the System Configuration
• Administrator of the Security System
The system operator can monitor and control all system nodes in a
single interface. With the help of software, he can initialize or
terminate the work of any script, use additional safety and conduct
self-test of the nodes.
GTS can be integrated with other safety systems due to the presence of
API. It greatly simplifies the implementation of the system. GTS client
has three workspaces.

12. INDUSTRIAL ZONE HARDWARE
Management Node is the autonomous system with its own set of
plug-executive mechanisms, which can make independent
decisions and resolve problems based on the data received from
other Sensors and other Management Nodes. It provides high
fault tolerance of the system, even in the case of loss of access to
the GTS server. Сommunication protocol for data exchange
between the GTS server and Management Nodes was designed by
our engineers according to the specifications. It is running over the
GTS Application Protocol for RS-485.
Executive Mechanisms represents any external system that needs
to be managed. This may be an emergency removal of gas, electric
locks on the doors, alarm systems etc.
Sensors are attached to the Hub

13. INDUSTRIAL ZONE NETWORK
We have chosen IEA/TIA-485 network for several reasons :
• Long range communication distance – 1200 m over the lines
• It can contain up to 256 devices
• Simple organization of lines, type of network connection is bus
• Balanced transmission line
GTS Network Layers
Standard IEA/TIA-485 has physical and data link layers. Existing data
link layer protocols did not suit us, so our team designed own data
communication protocol – GTS Application Protocol for RS-485.
It was optimized corresponding to the specifications, in order to
GTS Application Frame
increase the line capacity and reduce the device response time. Error
control system was used for maintaining data integrity. Network was
implemented utilizing the master-slave arrangement.
