FLEET-DEQ (Monitoring Control and Rescue System)
1. Features and Capacities of the System
The System is intended for the tracking of the group of vessels, belonging to the company.
The System allows to:
If the user doesn't have the chart of any region, the so-called Synthetic chart, made on basis of the heights of the earth's surface with a step of 30 seconds, is given to the user.
DBMS (Data Base Managment System) PostgreSQL is used for storing of communication and information about the vessels, which makes possible for user to develop and to use its own programs for processing of this information.
The System is built according to the configuration of the final customer - WEB server. Any WEB - browser, which supports standards DHTML and CSS, particularly Internet Explorer 6.0, Netscape 7.0, Mozilla working under the control of the operating systems Linux and Windows, can appear as a client. The System does not require the installation of any specialized programs at the customer work sites. Work sites can be territorially spread; it is also possible to work with the system through the global Internet network. Server - computer is under the control of the operating system Linux. In case of obtaining communications about the vessel's position by e-mail, the server must have capabilities for the connection to the Internet network for obtaining the mail communication. Client place can work under OC Windows control (the most common OC at the given moment) and under the OC Linux control. The customer system, who works under the OC Linux control, is reliably protected from the virus attacks and the attempts of the unsanctioned access.
The System users are divided into the classes according to the right of access to the system. The system administrator assigns one or several roles for each user, on basis of which he can carry out in the system these or other actions.
Typical roles:
The roles quantity and the users rights in each role can be invidually disposed for the concrete system installation. Besides roles, the groups can also be determinate for the users. The user can just manage the vessels of his group.
4. Reception of communications about the vessel position
The System can receive communication about the vessel position using electronic mail (the protocol - SMTP). For that, the user will find
a mailbox in the server of the system, into which must come the communications from company's vessels. The work is also possible when
communications enter into another (external) mailbox). The System can ask periodically this mailbox (by the protocol POP3) and take
communications about position away from there. The regime of taking communications without their removal from the mailbox is also possible;
it allows using this system with another monitoring system. The sources of communications - air terminals Inmarsat C, AIS (in that case this
one requires the installation of the sub-system of transfer of communications AIS) or formatted e-mail communications. In the future, the
reception of communications will also be possible from other sources - SMS, air terminals Thuraya and so on.

On the chart, there is:
Current position indicator
Vessels symbols  
Date and time
The selected vessel is noted as
With the scale change, the vessels symbols change too and new elements appear.
In the information window, are also located buttons for the monitoring of the route construction and also switching on/switching off
the position indicator and the distance calculator.

6. The Hide function - Hides the information window
The point is
intended to turn the information window into an icon with purpose to maximize the chart space.
A click on the icon opens the information window again.

7. The Chart function - control of the chart
The point is intended for the chart mapping control. Here, it is possible to change the scale of the reflected chart, using Zoom+ and
Zoom- buttons and/or using the list of scale selection. The N-W, N, N-E, W, E, S-W, S, S-E buttons are intended for moving the reflected
region to the appropriate direction, the C button - for centering the chart according to the current position. The Undo and Redo buttons
serve to cancel the last according to the change of reflect. The Undo and Redo buttons also act for the control of changes in the reflected
regions produced using the keyboard or the mouse.

The system can show the ARCS and BSB formats charts; in the nearest future it will be able to support charts of other sizes. The charts collection for the region which interests the user must be acquired by the system user. The synthetic chart, made on basis of the chart of heights of the earth's surface with a step of 30 seconds, is delivered with the system. The minimum of necessary objects (ports, geographical names, depth) is located on the synthetic chart for the tasks of vessels monitoring. The synthetic chart can also be recommended for the work place, connected with the server by means of the low speed line of communications - substantially, it has a smaller size than the chart of other formats.
In case of the presence of several charts for this region, the user has a possibility to select the necessary collection of charts.
11. To switch on/off the position indicator
The button switches on/off the mapping of
the geographical coordinates of the mouse cursor.
The button
switches on/switches off the distance calculator - the distance mapping (on the loxodromic) and the course,
from the position indicator to the mouse cursor.
Route consists of turning points. Turning
point is shown on the chart by flag with the label, in which are written the distance on the loxodromic and the course, for the motion to
the following turning point. One of the turning points is a current point for the route edition. This point is designated by a red flag.
The selection of the current point is done by the mouse. On pressing the Enter button, a turning point is put after the current point and
all points are renumbered. On pressing the DEL button the current point is moved away. The turning point can also be added/moved away with
the calculator buttons. The current route length is shown in the left lower angle of the screen.

14. Vessel function - information about the selected vessel
This point serves for mapping and correction of the information about the selected vessel (when the user has the appropriated privileges). The vessel is selected with the given list or by the mouse clicking on the image of the vessel on the chart.
The sub-paragraph Info of this point, serves for changing the vessel's data, which determine its view on the chart (Type determines the vessels silhouette, Color, respectively, its colour). After data's editing, it is necessary to press the "OK" key to fix the changes.
"Find" button serves for searching the selected vessel and for centering the chart relatively to it.
The sub-paragraph Status - to enter the communication about the emergency or about the vessel's status change (Normal/Shipyard).
The sub-paragraph Add. Info - the control (oversee)/the addition of the short notes about the vessel, and also, of the text communications came from the vessel.
The sub-paragraph Messages - the control (oversee) and (with presence of rights) the correction about the vessel position. Here, it's also possible to add new communication about the position with the button:
It's necessary to press the Ref num field of the appropriate communication for the correction
of the communication about the position.
In this case, the position of the current
transmission will appear on the chart and the form for the transmission editing - in the information window. The new coordinates can be
removed from the chart using the current position indicator.
"OK" button - fixes changes,
"Cancel" - cancels editing,
"Reset" - returns the communication to the initial state,
"Delete" - moves away the given communication.

15. Group function - information about all company's vessels
The vessel's name and code, the time of the last transmission, the distance to the selected vessel in miles (on the loxodromic) and the vessel's state are represented in the table.
Pressing the appropriate inscription of title, the table is sorted on this column. Thus, in order to find all vessels the most nearest to the selected vessel, it is necessary to press the Distance title.
Furthermore, in the table are also present manager buttons:
Serves for the search of the vessel (analogous with the "Find" button in point Vessel).
Draws a line
from the given vessel to the selected one.

18. Options function - options of the layout of the chart and selection of the time zone
The point is used to select the mode of the optimum layout for the given working place. Here, it is possible to select the time zone,
the pallet, the type of reflected chart - Synthetic or Navigation, the mode of layout of the ports (for the Synthetic chart), of the vessels
and the size of the police for the inscriptions on the chart.
19. Logoff function - to disconnect the system
After having achieved the work with the system on a given working place, it's necessary to be disconnected from the server. If it is not done (for example, only to close the browser window) so with the following connection to the system, it is the session of the same user under the same name which will be continued. The user's session is safeguarded approximately 10-15 minutes, and, if another user uses your computer during this time, he will have the possibility to continue work with the system having your rights. To avoid it, it is necessary to be always disconnected from the server when you are leaving the work place. Also, Logoff makes possible to the user to enter in the system under another name and another password, for example, in order to increase its privileges in the system.
