Description
Technical field
The invention belongs to gate safety detection technology fields, and in particular to the telescopic laser scanning suitable for gate
Detection system and its control method.
Background technique
With the continuous quickening of urbanization process, the application of rail traffic is also more and more common.It is handed over compared to other cities
For way system, the freight volume of rail traffic is big, punctuality rate is high, can greatly facilitate the trip of people, and rail traffic is often not
There is very obvious action in the road surface running vehicle space for occupying automobile, public transport for improving urban congestion problem.
During the operation of rail traffic, generally platform door system can be set on its platform, be used for platform and rail
Row distinguishes, and realizes getting on or off the bus for passenger.Due to consideration that the train limit in train travelling process, platform door system are set
It sets to generally require to meet and has certain spacing between the train that stops, so that there are one between platform door system and the train that stops
The gap of fixed width degree, causes platform door system to there is some potential safety problems in the process of running.In recent years, rail traffic passenger
The accident being sandwiched between the gate of closing and train door is commonplace, and this accident is particularly susceptible generation in gate and column
Passenger still wants to situation crowded when the situation for squeezing into vehicle by force or upper Train when car door will close.
Obviously, the safety to promote rail transportation operation, it is necessary first to which passenger improves awareness of safety；Secondly, it is also desirable to
Relevant improvement is carried out to existing rail traffic station, to promote the safety of station operation.Therefore, much operation department is in-orbit
Be additionally arranged anti-pinch safety measure in road traffic platform, existing anti-pinch safety measure generally there are several types of: 1, be arranged AT STATION
Correlation active infrared line detection system, generally includes the infrared transmitting tube for being divided into platform two sides and infrared electro receives
Pipe, emits infrared signal into the space between gate and train from infrared transmitting tube, and by infrared electro reception pipe pair
It is received.When there is barrier between gate and train, infrared receiving tube cannot receive the infrared light of opposite sending
Signal and issue alarm；2, correlation laser detection system is set AT STATION, Laser emission is respectively set by both ends AT STATION
Machine and terminal receiver emit laser signal, then the modulation that will be received by receiver from laser transmitter to terminal receiver
Optical signal is converted into corresponding electric signal, when light beam is interdicted, then alarm signal is issued to control host, to ensure gate
The safety of system operation.
Although above two system can lift station operation to a certain extent safety, reduce passenger and be sandwiched in platform
The case where before door and car body, generates.But corresponding limitation is also individually present in two kinds of systems, such as infra-red detection
For system, due to infrared transmitting tube issue light beam the angle of divergence and hot spot it is often larger, power density decaying is big when transmission,
Narrow gap is easy to appear irregular reference phenomenon when transmitting and fails to report alert or disorderly alarm, causes accuracy poor；And for swashing
For optical detection system, due to the rectilinear propagation of laser transfer, cause laser in parallel to penetrating there are certain check frequency, detection
Accuracy, which is unable to get, to be fully ensured that；Meanwhile above two system generally requires intrusion train limit in setting, is to detection
The setting stability of system and the safety in operation of train there are certain influence, be unable to fully to meet detection system on platform
Setting requirements；In addition, above two detection system is in the long-term use, it will usually because the vibration of environment generates position
It moves, causes detection process deviation occur and report an error, need often artificially to be overhauled and safeguarded, increase the operation cost at station,
Cause great inconvenience.
