Further, this diesel rail motor car fire alarm fire extinguishing system, also comprises:
DDU display screen---be arranged in each car drivers' cab, be connected with Train Control and management system.
Below this fire alarm and automatic fire extinguishing system are described in further detail:
1, detection and warning.
Fire alarm control unit main frame, for receiving the alarm signal that under the interior Smoke Detector of power distribution cabinet and drivers' cab and car, temp.-sensing wire sends, records warning message simultaneously, and by the CANopen interface of communicating by letter with TCMS, warning message is uploaded to TCMS system.In the time there is the condition of a fire, system will be sent audible and visible alarm at driver's cabin, and can pass through DDU query-related information.
2, fault alarm.
In the time of the faults such as the line between fire alarm control unit main frame and smoke detector is opened a way, short circuit, fire alarm control unit main frame sends the sound, the light fault-signal that there are obvious difference with fire alarm.And send fault-signal to TCMS, and showing fault message by drivers' cab DDU display screen, malfunction indicator lamp should be able to keep before fault is got rid of.After fault is got rid of, malfunction indicator lamp energy automatic distinguishing.
Event of failure comprises that temp.-sensing wire does not connect, Point-type fire detectors open circuit, short circuit, pollution etc.
3, drivers' cab sound and light alarm and noise reduction.
In the time having fire to occur, fire alarm control unit main frame sends sound and light alarm signal by hard signal, the drivers' cab acoustic-optic alarm activating will be triggered, and send fire alarm sound simultaneously, and " fire alarm " indicator lamp is bright, prompting driver has fire alarm to occur, driver can be turned down fire alarm sound or fire alarm sound is closed by switch, and fire lamp continues to light, until fire is eliminated, press SR on controller, alarm of fire signal is eliminated.
4, the function of putting out a fire, cut off the electricity supply.
For automatically moving and add manual intervention mode, when system is automatic mode, there is the information of reporting a fire when system detects fire in system.In the time that under car body, temp.-sensing wire is reported a fire, system starts relevant fire extinguishing device jet fire-fighting powder automatically, puts out burning things which may cause a fire disaster and automatically cuts off train AC380V power supply.
Press the hand push button being positioned on guest room power distribution cabinet and can manually boot extinguishing device, in order to prevent maloperation, over cap (adding lead sealing) is installed on hand push button; in emergency circumstances; destroy over cap, press the button and manually boot extinguishing device, fire under car is sued and laboured.
This fire alarm and automatic fire extinguishing system aim at the design of DMU Diesel Multiple Unit; native system adopts heat detection line to carry out detection; and ultra-fine dry powder fire suppression bottle is installed around diesel engine; in the time that diesel engine has fire to occur around, system automatic triggering of automatic alarm while extinguishing device extinguishes rapidly burning things which may cause a fire disaster, the safety of protection personnel and vehicle.
