Description

The invention relates to systems of security and fire alarms and automatic fire extinguishing, and in particular to systems of security and fire alarm and automatic fire extinguishing, adapted for use in rolling stock.

A known fire alarm system and fire extinguishing control in mobile vehicles (RU 67454 U1 (EPOTOS Limited Liability Company (EPOTOS LLC) (RU)), 10.27.2007), including a fire detector, fire extinguishing means and a button for starting them in manual mode, equipped with a protective device against unauthorized starting, a device for collecting information and monitoring fault lines, fire detector states, combined with the ability to perform the functions of a logical unit, which is directly connected to the detector, and the light device and the sound signal device are connected in series, and the manual start button is remotely connected to the corresponding fire extinguishing means, while the system is additionally equipped with an uninterruptible power supply unit, configured to transmit the onboard power voltage through the conversion module to the logic unit, and is also made with the ability to transmit a signal over communication channels in an amount of not more than two.

The disadvantages of this system include the lack of the ability to work with several sections, the inability to turn off the power supply of technological equipment before extinguishing a fire, and the lack of automatic fire extinguishing.

Closest to the technical nature of the claimed system includes a fire alarm and fire extinguishing control in mobile vehicles (UA 64293 (Kalashnik Alexander Anatolyevich, UA), 10.11.2011), containing control, indication and control units located in each section of the locomotive, combined through switching unit in a single system with heat and smoke detectors, sound and light annunciators, fire extinguishing actuators, backup power supply, remote controls, device you communication locomotives, having the ability to work in manual or automatic mode, as well as the ability to run the main and backup fire extinguishing agent.

This system also has a number of significant drawbacks, which include the lack of the ability to monitor the status of backup batteries, which is important when working in automatic mode when locomotives are in a cold sludge state, the absence of a security function, the absence of a system adapter with a motion parameter recorder (RPD) , in the memory of which, in accordance with the regulations, information is stored on the movement and condition of the locomotive, the lack of a shutdown function of technological equipment before starting com fire extinguishing systems.

The aim of the present invention is to expand the functionality of the system, which are:

- when the locomotive crew is in the locomotive in the registration of emergency situations (fire or system malfunction) in the internal memory; ensuring the transmission of appropriate messages to the driver, the duty depot (via the radio channel through the adapter of the radio station), as well as to the registrar of the train's automatic driving system with time synchronization; disconnecting traction collection circuits by lowering the pantograph and turning off electric locomotive fans or breaking traction collection circuits and stopping a diesel engine for diesel locomotives before starting fire extinguishing systems, transmitting information about all changes in the state of the system to the server of a unified monitoring system for the operation of on-board locomotive systems;

- when the locomotive is in a sludge state in the automatic notification of the duty officer on the depot about putting the locomotive under guard, about disarming the locomotive, about emergency situations (fire or system malfunction or unauthorized entry into the locomotive); monitoring the level of charge of the battery (battery) of the uninterruptible power supply with the function of generating and transmitting the corresponding voice message to the duty officer in the depot if the battery is discharged to a critical level; transfer of information about all changes in the state of the system to the server of a unified system for monitoring the operation of onboard systems of locomotives.

This goal is achieved by the fact that the claimed system additionally includes door status sensors, a system for monitoring the charge level of the uninterruptible power supply batteries, an adapter for the registrar of motion parameters and an adapter for the Russian Railways data network, which provides data on the system’s operation to the server of the unified monitoring system airborne locomotive systems.

A comparative analysis with an analogue and a prototype allows us to conclude that the hallmarks of the claimed object are the presence of door status sensors, a battery charge monitoring system for an uninterruptible power supply, an adapter for the registrar of traffic parameters and an adapter for the Russian Railways data network. Thus, the claimed object meets the criterion of "novelty."

Comparison of the claimed object with other technical solutions in this technical field did not allow to reveal in them the signs that distinguish the claimed solution from the prototype, which allows us to conclude that the criterion of "significant differences".

The system can function in three modes: “MANUAL”, “MANUAL WITH DELAY” and “AUTOMATIC”.

At all operating modes, the system stores information about the operation of the detectors in the fire alarm loops, malfunctions in the fire loops circuits, and in the start circuits of the fire extinguishing actuators in non-volatile memory. When the memory is full, the oldest entries are automatically deleted.

When the System is turned on, the “MANUAL” mode is automatically set, which is used when the locomotive brigade is in the locomotive and is used for emergency fire fighting in a section where there are no locomotive brigades.

The “MANUAL WITH DELAY” mode is used when the locomotive crew is in the locomotive and is the main mode of the System in motion. The time delay before the launch of the fire extinguishing actuators is necessary to enable the locomotive crew to evacuate. In this mode, the system allows you to track smoke and fires in controlled areas, alert the locomotive crew and the duty officer on the depot (via the radio adapter), send the appropriate messages to the train motion parameters recorder and transmit information about the change in the state of the system to the server of the unified system for monitoring the operation of onboard locomotive systems through the adapter of the data network of Russian Railways.

At the same time, the system ensures the manual start of the fire extinguishing actuators and the automatic shutdown of the locomotive’s processing equipment by lowering the pantograph and turning off the fans when used in electric locomotives or by breaking the traction and stopping circuits of a diesel engine when used in diesel locomotives before launching the extinguishing executive means.

The “AUTOMATIC” mode is used in the absence of a locomotive crew when the locomotive is in a state of sludge.

When this mode is activated by means of the adapter of the radio station, the duty officer on the depot is automatically sent a message about arming the locomotive. The system goes into automatic mode, during which the status of the detectors, the battery level of the uninterruptible power supply battery, the condition of the doors of the locomotive and unauthorized interference with the system are monitored. Any changes in the state of the system are recorded in the system’s memory and transferred to the server of the unified system for monitoring the operation of on-board locomotive systems using the adapter of the Russian Railways data network.

When the locomotive is in the lag on duty, the duty station sends messages about the detection of a fire situation, about arming and disarming, about unauthorized entry into the locomotive or unauthorized interference with the system, about a critical discharge of the uninterruptible power supply battery via a radio channel through the train radio station locomotive numbers.

When the detectors are triggered, the system extinguishes automatically.

This system allows you to significantly expand the functionality of the system by early automatic detection of a fire by smoke or by raising the temperature in protected areas, its quick registration with the issuance of information about both the fire and the system malfunction, indicating the appropriate location in the locomotive, extinguishing the fire in automatic or manual control mode, as well as timely notification of the duty officer on the depot about the detection of an emergency with an indication of the locomotive number. Thus the objective of the invention is achieved.
