4）Laser detector enters stand-by operation state, waits next train to arrive.
The mode of operation of the system
High ferro platform security mask door barrier laser detection and alarm system possesses two kinds of mode of operations：Normal mode of operation, every
From mode of operation.
In normal mode of operation, the controlled output reality of high ferro platform security mask door barrier laser detection and alarm system
When access safe door safety circuit；When " isolation " pattern is switched to, " isolation " display lamp is bright.Now, high ferro platform protective screen
Cover a barrier laser detection and alarm system because cut off safety door close the door locking signal input quit work, but do not affect row
Car normally runs and safety door system normal work.
Under normal circumstances, high ferro platform security mask door barrier laser detection and alarm system is in normal mode of operation.
When abnormal conditions or overhaul of the equipments occurs in system, system can be made to be switched to isolation mode.The switching of isolation mode is by operative position
The switching key switch of control main frame is realized on the PSL and car control room IBP disks.
Two working conditions of laser detector under normal mode of operation
In the normal mode of operation, laser detector is divided into stand-by operation state and detection operations state.
Holding state：When control main frame does not receive shield door " door in place and lock signal ", control main frame not closed laser
The power supply of detector, laser detector are in dead electricity holding state.
Detection operations state：When train passenger input is completed up and down, and shield door is closed and after locking, PSC systems are given
Laser detector sends shield door and cuts out and lock；Control main frame receives this side shield door and closes and lock, and visits to this group of laser
Survey device to be powered, and the barrier between all columns in the side is detected, send after 200 milliseconds of barrier is persistently detected
Alarm signal, barrier recover normal condition after excluding 200 milliseconds.
Under detection operations state, when laser acquisition continues not detect for 5 seconds object, laser detector will be into treating
Machine state, wait are circulated next time.As there is around here obstruction warning, or fault detect occurs extremely and causing trouble warning,
Laser acquisition can persistently detect and send relative alarm, until barrier removing or troubleshooting continue to visit for 5 seconds after finishing again
Survey, after confirming normally, enter holding state, wait is circulated next time.

Source 220VAC；
1.4 security controls are exported（Dry contact）
There is one group of security control output relay contact in the control main frame of system.It is when laser is to detection of obstacles, such as accessible
Thing blocks the laser then closing of contact；Laser is blocked if any barrier, and then contact disconnects.The relay contact of security control output, leads to
The terminal block for crossing the control main frame of system is drawn.
1.5 obstruction warnings are exported（1 road output port）Export with device failure alert（1 road output port）
Obstruction warning can be directly sent when having barrier to block laser, obstruction warning output port disconnects 24VDC, sends out to PSL
Go out alarm signal.The relay contact of security control output disconnects.
Obstruction warning is directed to during laser detector itself fail, failure includes that the power supply of emitter is damaged, sent out
Penetrate plate quit work, laser tube damage, and receptor power supply damage, receiver board quit work and opto-electronic receiver part damage,
When there is one failure of any of which, all can be oriented at once and sending obstruction warning.Now, obstruction warning output and fault alarm
Output port can disconnect 24VDC, send alarm signal to PSL.Meanwhile, the relay contact of security control output disconnects.
When the control main frame of system is powered to laser detector, and laser detector is reported to the police to the control main frame of system
Transmission line occur abnormal, fault detect warning, and synchronization steering obstruction warning will be sent.Now, obstruction warning output and
Fault alarm output port can disconnect 24VDC, send alarm signal to PSL.Meanwhile, the relay contact of security control output
Disconnect.
1.6 laser acquisitions are exported（1 road output port）
When laser detector is in detection operations state, signal is enabled to PSL output 12VDC detectors；When quitting work, cut-out
12VDC is exported.
2. display lamp on system control main frame panel
System control main frame panel ledss include：Power supply lamp, isolation lamp, control input lamp, laser acquisition lamp, failure inspection
Survey lamp and obstruction warning lamp.
2.1 power supply lamps（White lamps）
Brilliant white lamp during electricity in control main frame, during power failure, lamp goes out.
2.2 isolation lamps（Red colored lamp）
Key switch above PSL was operated to after " isolation ", control main frame receives the isolated instructions from PSL, control master
Machine cutting-off controlling input port, into isolation mode of operation, isolates when red.
2.3 bypass lamps（Amber light）
Key switch above PSL was operated to after " isolation ", laser controlling main frame enters isolation mode of operation, simultaneity factor
Into bypass mode, bypass amber light is bright.
After isolation is released, bypass mode is also released simultaneously, and bypass amber light goes out.
2.4 control input lamps（Green light）
After accessing safety door closing locking signal, on control main frame panel, control input lamp gives a green light.When safety door is opened, control
System input lamp goes out.
2.5 laser acquisition lamps（Green light）
When laser detector is in detection operations state, the laser acquisition lamp on the control main frame panel of system gives a green light.
2.6 fault detect lamps（Red green bi-colour light）
, to control main frame to each laser detector electric power thus supplied, and laser detector is to the warning transmission line of control main frame for system
Road broken string situation is detected.When detecting normal, the fault detect lamp on the control main frame panel of system gives a green light；And detect different
Chang Shi, fault detect lamp report to the police and send out a warning.
While above-mentioned fault detect occurs to report to the police, synchronization steering obstruction warning, obstruction warning lamp are sent out a warning simultaneously.
2.7 obstruction warning lamps（Red green bi-colour light）
To detection of obstacles, during clear, obstruction warning lamp gives a green light laser；When having barrier, obstruction warning lamp sends out a warning.
The installation of 3.1 main frames
