Description
Technical Field
The invention relates to the field of subway shielding door shielding anti-pinch devices, in particular to an intelligent shielding door shielding anti-pinch device applicable to an unmanned subway.
Background
The subway shielding door is used as a safety device in the urban rail transit system, not only builds a safe and comfortable waiting environment for passengers, but also has the advantages of energy conservation, environmental protection, waiting area increase and the like. But the screen doors also conceal a non-negligible risk, passengers may become trapped in the platform gap between the screen doors and the train due to subway train envelope and equipment confinement limitations. Such pinch accidents occur occasionally throughout the country, which can delay train operation and also cause serious injury to passengers. In recent years, full-automatic driving and system control of rail transit are rapidly developing, unmanned subways and full-automatic line operation are becoming a trend, and the problems of subway congestion and supersaturated transportation are becoming serious. Especially during peak early and late hours, the maximum full load rate of many train sections exceeds 120%, which increases the incidence of accidents in the platform gap.
The current mainstream anti-pinch device is mainly divided into two main types of physical anti-pinch detection and optical detection. The physical anti-pinch detection class mainly comprises an anti-pinch baffle installed on a shielding door and an anti-standing slope installed on a dock. The anti-pinch baffle is arranged on the shielding door, so that the cross section of the shielding door is increased, the contact area between the shielding door and a human body is larger, and when the door is closed, the human body prevents the resistance of the door from being transmitted through the baffle when the door is closed, so that the anti-pinch device is more sensitive. The anti-standing slope is used for preventing people from standing in the gap. The optical anti-pinch detection device mainly comprises three facilities, namely an infrared light curtain, a laser light curtain and an artificial lookout lamp strip. The infrared light curtain detection technology utilizes the infrared light beams emitted by the emitting end to sweep the gap of the platform, and if a certain infrared light beam is blocked at the receiving end, the foreign matters or people exist in the gap of the platform. Laser curtain detection systems similarly use multiple sets of laser transmit and receive devices to sweep the gap between stations. The manual observation lamp strip is a vertical lamp tube arranged on the platform, is usually arranged at the tail part of the platform, and judges whether a gap between the shielding door and the vehicle door is invaded by foreign matters or people according to the fact that whether a driver observes the lamp strip completely or not.
The prior art has the following problems:
because the train door and the shielding door are not linked systems, and the train door and the shielding door have anti-clamping functions, if the shielding door is closed and the train door is not closed, passengers can be extruded out of the train to enter a platform gap; if the train door is closed and the screen door is not closed, the passenger may not be able to get back to the platform and remain in the platform gap after the passenger is on the bus. When the shielding door is re-opened, the safety baffle originally used for enlarging the contact area is very likely to push the person out of the moving door area, and the standing slope is prevented so that the person can stand unstably, and the possibility that the person falls down the platform is increased.
The infrared light curtain detection technology is limited by detection distance, belongs to multi-section detection equipment, and needs to arrange multiple groups of equipment for joint detection. The technology is easy to be interfered by dust, insects and train vibration and refraction and reflection of complex light, and is easy to generate false detection. The laser light curtain detection technology is difficult to maintain and calibrate, and the workload is extremely high. The detection requirement of a train of subways can be met only by a plurality of groups of equipment, and the detection is also easy to be influenced by diffuse reflection, dust, train vibration and wind pressure, and has low accuracy. The manual lookout lamp strip has the problems of large blind area, unreliable equipment and the like, and is easy to be influenced by natural stray light and fatigue of a driver due to the naked eye visual judgment process of the driver, and is not suitable for an unmanned environment.

The inner side of the platform is provided with a tunnel foundation 10, and a track 9 is arranged on the tunnel foundation 10; the train body 6 is mounted on a rail 9 via train wheels 8.
The blocking detection system 25 is always in the active state; when the train door 7 and the shielding door are closed, and an object blocks the closing of the shielding door or the train door 7, the unit controller terminal 21 judges from the information obtained at the automatic train control system 19 and the door machine controller 23 that the door blocked by the object is the shielding door, the train door 7 or both of them have been blocked;
when the object is judged to obstruct the closing of the shielding door and the blocking detection system 25 does not reach the triggering condition, the situation that a person or the object invades the gap of the platform is not reported, the normal secondary opening of the shielding door is not interfered, and the shielding door is closed after the object is taken out;
when judging that the clamped object only blocks the train door 7, the train automatic control system 19 prohibits train starting, the unit controller terminal 21 transmits a signal to the door machine controller 23, and the door machine controller 23 instructs the transmission telescopic system 24 to push the blocking detection system 25 out to a specified position in the train direction and lock the blocking detection system on the envelope line of the train after confirming that the local control box 22 is in an automatic position; if the blocking detection system 25 touches an obstacle in the running process, the blocking detection system 25 is triggered, a trigger signal is transmitted to the door machine controller 23, and the door machine controller 23 instructs the blocking detection system 25 to be locked at the current position, so that the injury to a human body caused by secondary extrusion is prevented, and meanwhile, the effect of preventing the human body from entering a platform gap can be also achieved; after stopping locking completely, the blocking bar feeds back locking information to the door machine controller 23, the door machine controller is processed and transferred by the unit controller terminal 21, the train automatic control system 19 indicates the train door 7 to open for the second time, and meanwhile, an alarm is sent to the hand-held terminal of a platform worker, and after an object is taken out, the train door 7 is closed again and locked; the automatic train control system 19 informs the unit controller terminal 21 of the information of the locking of the train door 7, the unit controller terminal 21 informs the door machine controller 23 to instruct the transmission telescopic system 24 to reset the blocking detection system 25 after the train door 7 is normally locked, and then the automatic train control system 19 releases a train, and the train can be started to play a role in preventing the human body from being squeezed into a gap between the train and a platform.
When the shielding door and the train door 7 are locked and objects or people invade the platform gap, the people can contact with the blocking detection system 25 on the shielding door to trigger the bar-shaped micro switch 16, so that the blocking detection system 25 reports abnormal conditions to the door machine controller 23 and the unit controller terminal 21 step by step; the door machine controller 23 unlocks the shielding door and forces the local control box 22 to enter a reset mode after receiving the signal of the abnormal condition, and the unit controller terminal 21 informs the train automatic control system 19 to prohibit the train from starting and sends the information to the handheld terminal of the platform staff to give an alarm so as to ensure the safety of the operation of the staff and the train; after the clamped person or object leaves the platform gap, the door controller 23 confirms that the bar micro switch 16 of the blocking detection system 25 is not triggered any more, and the on-site control box 22 is switched from reset to automatic position by using a key after the manual confirmation of a station operator; after the local control box 22 is switched to the automatic position, the door machine controller 23 is informed to command the transmission telescopic system 24 to reset the blocking detection system 25, and after the blocking detection system 25 is reset, the shielding door is closed and locked again; the door machine controller 23 informs the unit controller terminal 21 of the information of the locking of the shielding door step by step; the unit controller terminal 21 then notifies the train automatic control system 19 to let go of the train, and the train can be started.
In this embodiment, the unit controller terminal 21 controls and monitors the operation of the whole subway shield door shield detection system, so that the exchange and the collection of the internal information of the system can be realized to realize the information exchange with other collaborative systems. The system can inquire the state of each sub-control unit, and control the on-site controller to command the system to operate according to the set conditions when the corresponding abnormal conditions occur, and the monitoring system operation condition receives feedback. It can store corresponding operation data at the same time, and has the functions of monitoring and diagnosis.
The control state of the single door can be switched by the local control box 22 (LCB), the control level and the control mode of the single door can be switched by a key switch, and when the system cannot automatically reset and remove obstacles, the local control box 22 can be switched to manual control to isolate the door system for manual treatment, so that other systems can be ensured to operate. The control strategy with new design can prevent the misoperation of a station operator from causing the wrong isolation of the unit to cause the confusion of a signal system. Common LCBs have automatic, manual on, manual off, and isolated four key positions. The automatic position allows the door machine controller 23 (Door Control Unit, DCU) to receive the command of the central control panel; the isolation position isolates the whole shielding door unit from the system, the power supply of the unit is cut off, so that the unit is convenient to maintain, and the safety loop of the unit is bypassed at the moment; the manual on and off commands do not execute the central control panel command but do, at which point the unit safety loop is bypassed. The LCB designed by the system is additionally provided with a reset key position. In the system strategy, when the shielding door unit is clamped or the blocking detection system judges that the shielding door unit is abnormal, the safety circuit is disconnected when the shielding door unit is switched from the automatic position to the manual opening position, and when the shielding door unit is switched from the manual closing position to the automatic position, the reset position is required to be switched firstly, the safety circuit is communicated and then is switched to the automatic position, so that a station operator is prevented from cutting off signals by mistake. If the manual operation is necessary, the emergency stop button on the platform must be pressed first to switch to the manual key position under the condition that the system is not reset.
The transmission telescopic system 24 is responsible for the operation of the blocking strip, and can utilize a right-angle worm gear motor arranged on the inner side of the shielding door frame to drive a crank to push the blocking strip to approach the train under the set condition, and lock the position of the blocking strip 15 when the blocking detection system 25 touches an object or a person.
The blocking detection system 25 is divided into a blocking bar and a detection system. The blocking strip is embedded in the shielding door frame at ordinary times, and is pushed out through the transmission telescopic system 24 under the set condition, so that personnel in the train can be limited to block the personnel from entering the platform gap. The detection system is arranged on the blocking strip, and adopts a bar switch (safe touch edge) with higher sensitivity and simpler structural design to carry out touch detection, so that larger foreign matters and human bodies in a platform gap can be detected, and the maximum transmission distance of the blocking strip can also be detected.

when judging that the clamped object only blocks the train door (7), the automatic train control system (19) prohibits train starting, the unit controller terminal (21) transmits a signal to the door machine controller (23), and the door machine controller (23) confirms that the local control box (22) is in an automatic position and then instructs the transmission telescopic system (24) to push the blocking detection system (25) to a specified position in the train direction and lock the blocking detection system on an envelope line of the train; if the blocking detection system (25) touches an obstacle in the running process, the blocking detection system (25) is triggered, a trigger signal is transmitted to the door machine controller (23), and the door machine controller (23) indicates that the blocking detection system (25) is locked at the current position; after the blocking bar is completely stopped and locked, locking information is fed back to the door machine controller (23), the train door (7) is instructed to be opened for the second time by the train automatic control system (19) after being processed and transferred by the unit controller terminal (21), meanwhile, an alarm is sent to a handheld terminal of a platform worker, and after the object is taken out, the train door (7) is closed and locked again; the automatic train control system (19) informs the unit controller terminal (21) of the information of locking the train door (7), the unit controller terminal (21) further informs the door machine controller (23) to instruct the transmission telescopic system (24) to reset the blocking detection system (25) after the train door (7) is normally locked, and then the automatic train control system (19) releases a train;
when the shielding door and the train door (7) are both locked but the object or the person invades a platform gap, the person can contact with the blocking detection system (25) on the shielding door to trigger the bar-shaped micro switch (16), so that the blocking detection system (25) reports abnormal conditions step by step to the door machine controller (23) and the unit controller terminal (21); the door machine controller (23) unlocks the shielding door and forces the local control box (22) to enter a reset mode after receiving the signal of the abnormal condition, and the unit controller terminal (21) informs the train automatic control system (19) to prohibit the train from starting and sends the information to a handheld terminal of a platform staff for warning after receiving the signal; after the person or the object to be clamped leaves the platform gap, the door machine controller (23) confirms that the bar-shaped micro-switch (16) of the blocking detection system (25) is not triggered any more,
switching the in-situ control box (22) from a reset to an automatic position using a key after manual confirmation by a station operator; after the local control box (22) is switched to an automatic position, the door machine controller (23) is informed to command the transmission telescopic system (24) to reset the blocking detection system (25), and after the blocking detection system (25) is reset, the shielding door is closed and locked again; the door machine controller (23) informs the unit controller terminal (21) of the information of locking the shielding door step by step; the unit controller terminal (21) then notifies the train automatic control system (19) to let go of the train.
