When the signal that speed detector output reflection train speed is less than minimum speed is spent or mist detecting device output reflects cigarette
When mistiness degree is more than the signal of setting Cmax, central processing unit judges emergency occur, and controls Lighting control
Circuit 5 opens the lighting apparatus in tunnel.
Each manual switch 6 is connected in bus with central processing unit 4.This part composition manual-operated emergent part, referring to
Fig. 2.When manual switch is triggered, it exports trigger signal to bus.Central processing unit 4 is used for touching on bus is received
Illumination control circuit 5 is controlled to open the lighting apparatus 8 in tunnel during signalling, the control illumination control when being received again by trigger signal
Circuit 5 processed changes the state of the lighting apparatus 8 in tunnel, i.e., is when opening before, is closing now；Lighting apparatus is pass before
It is unlatching now during closed state.
In automatic emergency part：
Train speed detection device, mist detecting device are installed in tunnel.
Train speed detection device is used to detecting the form speed of train, mist detecting device be used to detect in tunnel whether
The dangerous situations such as generation fire.
Both transmit a signal to central processing unit；Central processing unit judges whether occur according to the signal received
Emergency, if then controlling the emergency set in tunnel to open.
More specifically, central processing unit exports reflection train speed less than minimum speed in train speed detection device
During signal or when mist detecting device output reflection smokescope is more than the signal of setting Cmax, central processing unit is sentenced
It is disconnected emergency occur.
Referring to Fig. 1, central processing unit 4 can be realized by intelligent chips such as microcontrollers, itself and the Lighting control in tunnel are electric
Road 5 is connected with signal, and illumination control circuit is lighting apparatus distribution box in the present embodiment, when being in an emergency, center
Processing unit control illumination control circuit opens the lighting apparatus in tunnel.
In other embodiments, the wind turbine in the also controllable tunnel of distribution box（For divulging information）And the switch of fire resistant doorsets, when
When central processing unit judges dangerous situation occur, distribution control box opens wind turbine and/or fire resistant doorsets.
The train speed detection device and mist detecting device of the present embodiment use is described in detail below.
Train speed detection device in the present embodiment is multigroup infrared shooting device, referring to Fig. 1, multigroup infrared emission dress
Put 2 radially to lay along tunnel 1, the length for being smaller than train of two adjacent groups.Every group of infrared shooting device includes infrared ray
Transmitting terminal 21 and infrared receiver end 22, infrared emitting end 21 are laid in the both sides with road with receiving terminal 22 respectively.During work
Infrared receiver end sends infrared ray, and receiving terminal exports high level " 1 " or low level " 0 " when detecting infrared ray, when both it
Between when having lighttight shelter, for example train crosses, and infrared receiver end output signal inverts, that is, exports low level
" 0 " or high level " 1 ".
Central processing unit 4 with every group of infrared shooting device 2 in train speed detection device there is signal to be connected, and receive
Its level exported.The time interval that a certain group of infrared shooting device level maintains inverted status is detected, this time interval is gone
Except the length of train vehicle body can obtain the speed of service of train, since train vehicle body is constant, will directly can be somebody's turn to do
Time interval and first kind time quantum（Equal to train length of wagon/minimum speed）Compare, such as larger than then think Train Stopping or
Person's velocity anomaly is slow, emergency occurs.
At the time of certain two groups adjacent infrared shooting device output levels reversions can also be detected in a further embodiment it
Between interval, by itself and the second class time quantum（Equal to distance/minimum speed between this two groups of infrared shooting devices）Compare, if
More than then thinking that Train Stopping or velocity anomaly are slow, there is emergency.
Mist detecting device in the present embodiment is other at least one set of infrared shooting device 3, mounting means and train
It is identical in speed detector.Central processing unit 4 connects with the infrared shooting device 3 in mist detecting device with signal
Connect.When infrared shooting device is blocked by the object of incomplete shading（Such as smog）, the level of infrared receiver end output can be in height
Between low level, and the density or concentration of level and shelter have relation.Central processing unit fills every group of infrared emission
The intensity of output signal is put compared with reflecting the signal strength of Cmax, when the output signal of certain group is less than（It is assuming that dense
Degree and level are in inverse ratio）Setting value, then judge that tunnel environment is in an emergency.
In manual-operated emergent part：
Referring to Fig. 3, manual switch 6 is distributed in multiple places in tunnel 1, and multiplying personnel when there is dangerous situation easy to row can be
Manual switch is found near oneself, opens lighting apparatus, emergency set is greatly shortened and starts the time, reduce infringement.Preferably
It is to be distributed in the both sides in tunnel, 6 away from 50 meters between the adjacent manual switch in the same side in tunnel 1.
Referring to Fig. 4, the manual switch includes voltage detecting circuit 61 and microcontroller 62 in a specific embodiment.
Voltage detecting circuit with microcontroller there is signal to be connected.
When manual switch is pressed, the voltage of voltage detecting circuit output changes, and microcontroller is in voltage detecting
During the voltage change of circuit output trigger signal is sent to bus.
More specifically, voltage detecting circuit include direct voltage source VCC, on ＆ off switch, resistance, on ＆ off switch it is in series with a resistor in
Between direct voltage source VCC and ground, the output terminal OUT of voltage detecting circuit is extracted out between on ＆ off switch and ground, referring to Fig. 5,
On ＆ off switch is selected can be automatically reset, and voltage detecting circuit exports low level when on ＆ off switch is not touched, when on ＆ off switch is pressed,
Voltage detecting circuit exports high level, and when on ＆ off switch resets, voltage detecting circuit exports low level, and one is occurred as soon as in such bus
A pulse signal.Microcontroller switches the state of bull switch after this pulse signal is detected.
As long as trigger signal as occurring in bus, the state of lighting apparatus will switch once, so any one
Manual switch can equality management and control lighting apparatus, the crash time is greatly saved.
In another embodiment, central processing unit timing is polled each manual switch definite each manual switch
Working status.Even if it was found that the manual switch to break down, and safeguarding, the reliability of system is improved.Specifically, each manual switch
With an address code for being different from other manual switches, central processing unit be used for by address code to each manual switch into
Row Roll-call polling, when occurring the signal identical with Self address code in bus, which sends a signal to bus,
Central processing unit thinks that the manual switch is normal after receiving this signal, continues to call the roll and detects next manual switch.In the middle
Central Processing Unit does not receive the answer signal for the manual switch called the roll within a certain period of time, then it is assumed that and the manual switch malfunctions,
And notify staff, such as send alarm and show address code.Staff needs what is overhauled according to address code energy fast positioning
Manual switch.
In a specific embodiment, the bull switch is relay.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
