The accessory system of a kind of station platform safety door and the interval safety of car door and its implementation

Technical field

The present invention relates to safety of urban transit field, relate to accessory system and its implementation of monitoring region security between rail traffic station platform safety door (shield door) and Train door based on the one of image recognition technology specifically.

Background technology

At present, city underground, the rail traffic platforms such as light rail are in order to energy-conservation and safety, security consideration in China mainly in order to prevent passenger from entering arbitrarily Gui Hang district, each city flower huge sum of money uses (overall height or half height) safety door (shield door) to be system ﹙ PSD ﹚ on rail traffic platform, the barrier shield of its system is arranged continuously around platform apart from the place of edge about 30CM, waited by platform district and rail travelling crane separates out, barrier shield is provided with safety door (shield door) passage of the upper Train of passenger, the Train door one_to_one corresponding that safety door (shield door) and track are stopped, safety door (shield door) is in closedown and locking states at ordinary times, it is by the door device of train itself, signal system and the common cooperation of safety door (shield door) control system realize safety door (shield door) and train door and synchronously open and close, thus avoid passenger to enter tunnel from platform causing danger.(shield door) Xi Tong ﹙ PSD ﹚ sets up the linked system of car-ground bidirectional data communication to signal ATC system (vehicle-mounted and trackside subsystem) based on Radio Transmission Technology with station platform safety door, form safety door (reciprocal interlocking relation between shield door) Xi Tong ﹙ PSD ﹚ and signal ATC system, when train once enter through the car-ground communication unit overlay area being arranged on platform terminal appropriate location, at once by trackside subsystem (signal trackside equipment) " catching ", and then set up based on the master-slave mode half-duplex high-speed data communication link of trackside subsystem exchange information, to be detected that by Precise Position System train speed is zero and in parking window when signal is vehicle-mounted, and be applied with anti-slip braking, then show that train has possessed to open, to cut-off the condition of car door and station platform safety door (shield door), just permission door open command is sent, no matter adopt automatic door opening management mode, still open Door by Hand management mode, it sends door open command and is passed to Car's door controlling device and trackside subsystem (signal trackside equipment) respectively subsequently, door open command is delivered to safety door (shield door) Xi Tong ﹙ PSD ﹚ by trackside subsystem again, realize completing car door and safety door (shield door) unlatching respectively, when passenger is complete up and down, no matter adopt automatic door-closing management mode, still manually to close the door management mode, it sends instruction of closing the door and is passed to Car's door controlling device and trackside subsystem (signal trackside equipment) respectively, the instruction of closing the door again of trackside subsystem is delivered to safety door (shield door) Xi Tong ﹙ PSD ﹚, complete car door and safety door (shield door) closedown also locking respectively, it is vehicle-mounted that car door open/close state information is directly passed to signal, it is vehicle-mounted that safety door (shield door) open/close state information is passed to signal by trackside subsystem, receive " safety door (shield door) close and locking " state and " closing of the door locking " status information when signal is vehicle-mounted after simultaneously, just allow that train sets out.Those skilled in the art are known: when passenger is complete up and down, car door and safety door (shield door) all close and locking after, region clear between car door and safety door (shield door), then between car door with safety door (shield door) physical state in region and train enter the station come to a complete stop tail gate and safety door (shield door) when all not opening physical state identical.

That (the common cooperation of shield door) Xi Tong ﹙ PSD ﹚ realizes by the Car's door controlling device system of signal ATC system, train itself and safety door because safety door (shield door) and train door synchronously open and close, due to the otherness of each system signal transmission and execution, use time delay, can only accomplish synchronous in principle.Current, safety door (shield door) is provided with Train door with the opening sequence of Train door and first opens, and and then safety door (shield door) is opened; Or safety door (shield door) is first opened, and then Train door is opened, and safety door (shield door) and Train door are almost opened simultaneously in a word, and surrounding time difference only has several wonderful; Treat passenger loading, send and close after gate signal, the closing the door to be sequentially set with of safety door (shield door) and Train door first closes Train door, and then closes safety door (shield door); Or first close safety door (shield door), and then close Train door, safety door (shield door) and Train door are almost closed simultaneously in a word, and surrounding time difference only has several wonderful.Well-known: when safety door (shield door) and Train door are opened, to adopt Complete Synchronization or order different modes, do not exist by folder problem between safety door (shield door) and Train door, but when safety door (shield door) and Train door are closed, no matter take Complete Synchronization or order different modes all to exist between safety door (shield door) and Train door by the potential safety hazard of pressing from both sides.So all installed the safety device of anti-pinch additional in existing safety door (shield door) system, have respectively by each city screen door extensively adopt at anti-station, sliding door bottom design inclined-plane people's baffle plate, to stop the subjective passive type physics mode remained between slip every body and train door of passenger, and on safety door (shield door), design metal baffle (anti-clamping plate) carry out detecting obstacles thing, the closedown of sliding door can be hindered when running into obstruction, coordinate the detection system of door control unit, greatly can improve the active physics mode of the safety of safety door (shield door).But whether only rely on the mode of physics to detect between shield door and train has the existence of obstruction still to have significant limitation, in addition because attractive in appearance and vehicle gauge considered by needs, also unlikely sniffer is physically done very large, be full of whole gap space.So also there is the potential safety hazard of pressing from both sides people when the rail traffic station platform safety door (shield door) being only provided with passive type physics mode and the protection of active physics mode is closed with Train door, in recent years occur folder people event frequently be seen in media, as when 2007 07 month 15 day afternoon 3 34 points, Shanghai Rail Transit Line 1 Shanghai Gymnasium station is toward on the platform in shen village direction, the man of more than 20 year old gets on the bus by force when buzzer rings and shield door light stroboscopic, be stuck in the middle of train and safety door (shield door), and the tunnel that falls of being squeezed after launch train is dead, and for example 2014 on November 6, evening 7 time about, the Foundation of Beijing Metro Line 5 Hui Xin West Street Nan Kou woman that stands is sandwiched in the middle of safety door (shield door) and train, and dead by squeezing after launch train.So each urban rail traffic platform part part sets up contactless detection mode, the mode of the good infrared laser detecting of antijamming capability is generally selected to close to detect safety door (shield door) and Train door the safety device whether its gap rear has obstruction.As Shanghai Underground after in July, 2007 adopts at subway shield door installation infrared linear light curtain survey meter, the probe (transmitter and receiver) of infrared ray curtain survey meter is arranged on the left and right sides in car door and safety door (shield door) gap respectively, after Train door and station platform safety door (shield door) are closed completely, the infrared ray curtain survey meter that probe is arranged on both sides can launch infrared rays automatically, form one light curtain barrier, receiver can receive radiative signal and then represent normal, can dispatch a car, if accompany foreign matter blocking light curtain (passenger is pressed from both sides) between two fan doors, survey meter will send a warning in the very first time, stop outbound signaling, the driver in notice front does not start train, can allow to start train by stop alarm when obstruction is removed, to ensure passenger and vehicle borne safety.But adopt the mode of non-contact laser detection to come when protection safety door (shield door) and Train door are closed its interval by the problem of pressing from both sides, there is Installation and Debugging difficulty, not real-time advanced self-checking function, along with the passing of service time, ageing equipment or local damage, there will be wrong report, as transmitter damage or receiver puncture.Also document is had to record, as: " microcomputer application " the 3rd phase in 2011, " platform shield door intelligent control system based on image recognition technology " of 26-28 page, number of patent application be 200710045171.6 platform screen door intelligence system and application number be 200710045172.0 platform screen door intelligent control methods, be and use image recognition technology to replace in existing safety door (shield door) system region anti-pinch checkout gear between safety door (shield door) and Train door, form new safety door (shield door) system, because pre-depositing image template, As time goes on the heavy knot of camera lens dust, the problems such as the aging or damage of imageing sensor occur causing rate of false alarm will be more and more higher, and the environment such as light along with the passing of time also can change, the appearance of rate of false alarm can be increased the weight of, although i.e. anti-pinch, but when occurring there is no foreign matter, the problem by pressing from both sides can be reported to occur, and there is no video detecting unit self-checking function.And for example: number of patent application is the subway door safety monitoring system based on video light curtain of 20130284929.7, it is a kind of problem solving the rear anti-pinch of subway door closedown based on video image identification technology, its duty mentioning subway door video light curtain device is simply controlled, but how to control not relate at all, those skilled in the art record according to its manual and are interpreted as: receive when closing gate signal and start monitoring and identify, stop monitoring and identify after train starting.When foreign matter having been detected, having sent and stopping pass gate signal, prompting driver can not force to close the door and drives or automatically lock subway start up system; Foreign matter disappears, and receives door and shut signal, just can start train.When recognize there is foreign matter time, also the video image containing foreign matter can be sent display screen show, provide driver vigorously to examine and reference.But there is subway door video light curtain device and there is no self-checking function in this invention, can not recognition be to subway door video light curtain plant failure problem in advance, as aging or damage and there is the insecure problem of degradation under sensitivity in having dust, imageing sensor when camera lens in camera.

Because of unique passage that safety door (shield door) on the barrier shield of safety door on rail traffic platform (shield door) system is the upper Train of passenger, in order to ensure the Train door stopped just to safety door (shield door), facilitate passenger through the upper Train of safety door (shield door), the Kuan Du ﹙ clean Kai Du ﹚ of safety door (shield door) all arranges the width being greater than Train door, the wide degree ﹙ of safety door (shield door) only degree of opening ﹚ adopts with train stopping accuracy on track as benchmark, Kuan Du ﹙ clean Kai Du ﹚ is traditionally arranged to be the parking worst error that Train door width adds 2 times, if Train door width is 1.3 meters, when Train Stopping precision is positive and negative 30CM, the Kuan Du ﹙ clean Kai Du ﹚ of safety door (shield door) is set to 1.9 meters.Simultaneously well-known: on barrier shield, the height of safety door is generally, the height 2.8 ~ 3.2 meters of enclosed shielding every body, l.2 open type shield door height is generally ~ l.5 rice.The train of city underground, light rail often saves car length and is greater than 10 meters.
