Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
A kind of train fire detecting and alarm device, comprise fire detector and fire controller, fire detector adopts smog and temperature complex probe technology, the fire controller is provided with warning boom unit and detector's status pilot lamp, the standard configuration in every joint compartment is 6 fire detectors and 1 fire controller, wherein the fire controller is installed on the regulator cubicle on limit, steward rest room, every joint compartment, 6 smoke detectors are installed in passenger carriage two ends, toilet, washing room, switchgear building and electric panel room respectively, also can adjust according to the concrete needs of train.During operate as normal, 6 smoke detectors can be monitored the fire variable in real time, have judged whether fire alarm; The pyrotechnics controller then mainly is responsible for handling the fire alarm that is sent by detector, when there is fire alarm in system, warning buzzing buzzing, status lamp becomes redness, to remind train crews and passenger, and send alerting signal to train control unit (VCU), and Train Control and monitoring system (TCMS) obtain the state of car load fire alarm system by train bus-line (WTB), and its system architecture is as shown in Figure 1.
Described fire detector adopts the PIC series monolithic as control chip, carry out the intelligent detecting device of data interaction by serial communication module and host computer, it can find fire quickly, also in time generation is reported to the police, its susceptibility is increased dramatically, and reduced system's rate of false alarm effectively, have that instruction set is succinct, rich interface, low in energy consumption, volume is little, antijamming capability is strong, advantage such as cheap, easy to learn, be widely used in the detection field, the basic composition of fire detector as shown in Figure 2.
Described fire alarm control unit control No. six detectors state demonstration, hummer, send fault diagnosis signal and send alerting signal to VCU to detector, controller can be divided into five functional modules, as shown in Figure 3:
Processor online programming circuit module: single-chip microcomputer normally moves needed support circuit, as online programming interface, electrify restoration circuit etc.
Power converting circuit: in view of the superiority of digital signal opposing neighbourhood noise, almost all expensive voltage transitions chip is no longer adopted in the design of the controller of processing digital signal, but adopts electronic components such as triode, stabilivolt to build the cost performance height.
LED indicates logical circuit: for increasing system response time, the LED lamp module that is used for demonstration fire detector duty is directly controlled by the signal of detector, rather than is controlled by the MCU on the control panel.Have 6 tunnel totally 18 LED lamps on the controller, every Lu Youhuang, red, green three kinds of colors, wherein amber light represents fault, red light represents fire alarm, the normal operation of green light representative.
Buzzer drive circuit: consider that the one-chip machine port carrying load ability is limited, design class B push-pull power amplification circuit, and adopt rectangular wave drive hummer form, buzzing is ear-piercing more loud when making fire alarm.
The VCU control circuit: when detector was found fire alarm, fire alarm control unit was to the VCU output alarm signal, and this alerting signal can be sent to Train Control and central monitoring position by train bus-line, adopted the mode of Single-chip Controlling relay contact to realize.
A kind of train fire detecting and alarm device, adopt 9 core cylindrical connectors as the signaling interface between fire detector and fire controller, its signal has corresponding relation, and use 24V voltage as the high level of digital signal, 0V voltage is as the low level of digital signal, can effectively suppress electromagnetic interference (EMI) complicated on the motor train unit, improve signal transmission reliability between fire controller and fire detector.The fire controller links to each other with train control unit with No. 6 fire detectors by 48 pin Europlugs of standard.The intelligent detecting device when receiving the test signal that is produced by controller, is then carried out failure detection operations according to state output fire alarm/normal signal and the diagnostic signal of fire sensor.In case breaking out of fire, when the fire controller receives any one road detector alarm signal, just produce the sound and light alarm alarm, and to this joint compartment the train control unit output alarm signal, and train control unit is transferred to Train Control and monitoring system by train bus-line, and whole alarm flow as shown in Figure 4.
