Below this fire alarm and automatic fire extinguishing system are described in further detail:
1, detection and warning.
The fire alarm control unit main frame is used to receive the alarm signal that temp.-sensing wire sends under power distribution cabinet and interior cigarette sense probe of drivers' cab and the car, writes down warning message simultaneously, and the CANopen interface by communicating by letter with TCMS, and warning message is uploaded to the TCMS system.When the condition of a fire takes place, system will send audible and visible alarm at driver's cabin, and can pass through the DDU query-related information.
2, fault alarm.
When faults such as the line between fire alarm control unit main frame and the smoke detector is opened a way, short circuit, the fire alarm control unit main frame sends sound, the light fault-signal that obvious difference is arranged with fire alarm.And, showing fault message by drivers' cab DDU display screen to TCMS transmission fault-signal, malfunction indicator lamp should be able to keep before fault is got rid of.After fault was got rid of, malfunction indicator lamp can be extinguished automatically.
Event of failure comprises that temp.-sensing wire does not connect, point type smoke detector open circuit, short circuit, pollution etc.
3, drivers' cab sound and light alarm and noise reduction.
When fire takes place, the fire alarm control unit main frame sends the sound and light alarm signal by hard signal, the drivers' cab acoustic-optic alarm that activates will be triggered, and send the fire alarm sound simultaneously, and " fire alarm " indicator lamp is bright, the prompting driver has fire alarm to take place, the driver can turn down the fire alarm sound or the fire alarm sound is closed by switch, and fire lamp continues to light, and eliminates up to fire, press SR on the controller, the alarm of fire signal is eliminated.
4, the function of putting out a fire, cut off the electricity supply.
System adds manual intervention mode for moving automatically, when system is automatic mode, when system detects fire the information of reporting a fire takes place.When temp.-sensing wire was reported a fire under the car body, system started relevant fire extinguishing device jet fire-fighting powder automatically, put out burning things which may cause a fire disaster and cut off train AC380V power supply automatically.
Press the hand push button that is positioned on the guest room power distribution cabinet and can manually boot extinguishing device,, over cap (adding lead sealing) is installed on the hand push button in order to prevent maloperation; in emergency circumstances; destroy over cap, press the button and manually boot extinguishing device, fire under the 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 the heat detection line to carry out detection; and the ultra-fine dry powder fire suppression bottle is installed around the diesel engine; system reports to the police automatically and triggers extinguishing device simultaneously automatically and extinguish burning things which may cause a fire disaster rapidly, the safety of protection personnel and vehicle when having around the diesel engine fire to take place.
