Abstract
The invention discloses a method for preventing clamping during opening an inner swinging door of a passenger carriage. In the process of opening the inner swinging door of the passenger carriage, because a gap between a side edge of a door panel of the inner swinging door close to a doorframe and a door spindle is small, passengers may be injured under extreme conditions. The clamping preventing method comprises that: when a foreign body appears between the side edge of the door panel of the inner swinging door close to the doorframe and the door spindle, the inner swinging door cannot be normally opened, and has the following characteristics: 1, the pressure at the outlet end of a cylinder in a driving system is changed abnormally; 2, the closing time of the inner swinging door is overtime; and 3, the pressure in a weather strip of the door panel close to the edge of the doorframe is changed abnormally; signals are acquired by a sensor by utilizing the abnormal characteristics, and are fed back to a inner swinging door control system, or the inner swinging door control system directly acquires overtime signals; and after receiving the signals, the control system transmits the signals to a driving system and the driving system inversely drives the inner swinging door to close; therefore, the aim of preventing clamping is fulfilled. The clamping preventing method is safe and reliable, and effectively fills up the blank of the inner swinging door clamping preventing technology in the prior art.
Description
One, technical field
The present invention relates to a kind of method for preventing clamping during opening inner swinging door of passenger carriage.
Two, background technology
At present, the public transport inner swing door mechanism of Chinese city generally adopts anti-jamming device, prevents to crush the passenger under the situation of closing the door, and generally do not adopt anti-jamming device in the process of opening the door.Like this, very little in the process that inner swing door opens the door because in the door-plate near the gap of the side of doorframe and door-hinge, domestic the passenger appears crushing time and again, even the phenomenon of pinch off children arm, serious harm is to passenger's safety by bus.
Three, summary of the invention
1. goal of the invention
At the blank of present preventing clamping during opening inner swinging door of passenger carriage technical field, the invention provides a kind of safe and reliable inner swing door anti-pinch technology of opening the door.
2. technical scheme
Technical scheme of the present invention is as follows:
When foreign matter occurring between near the side of doorframe and door-hinge in the inner swinging door of passenger train door-plate, inner swing door can't be finished normal unlatching, and the inner swing door of this moment has following off-note: 1, the pressure of the cylinder outlet side in the drive system has ANOMALOUS VARIATIONS; 2, the inner swing door lockup is overtime; 3, door-plate is near doorframe limit adhesive tape internal pressure generation ANOMALOUS VARIATIONS, this anti-clamping method utilizes above-mentioned off-note by the sensor acquisition signal, feed back to the inner swing door control system, perhaps the inner swing door control system is directly gathered timeout signal, control system transmission signal is given drive system, drive systems inner swing door reverse drive is closed inner swing door, thereby reaches the purpose of anti-pinch.
3. beneficial effect:
The present invention has effectively filled up the blank of present preventing clamping during opening inner swinging door of passenger carriage technology, has improved the safety of passenger vehicle.
Four, specific embodiments
Specify the present invention by the following examples:
Embodiment 1:
In the adhesive tape of the close doorframe limit of inner swinging door of passenger train door-plate, pressure bladder is installed, when foreign matter occurring between near the side of doorframe and door-hinge in the inner swing door door-plate, producing pressure in the pressure bladder changes, this pressure changes by sensor acquisition, and the sensor feedback signal is given control system, and control system is given the drive system signal, the drive systems inner swing door is closed, thereby reaches the anti-pinch purpose.
Embodiment 2:
In the adhesive tape of the close doorframe limit of inner swinging door of passenger train door-plate, sensor installation, when foreign matter occurring between near the side of doorframe and door-hinge in the inner swing door door-plate, sensor acquisition is to the variation of pressure, the sensor feedback signal is given control system, control system is given the drive system signal, and the drive systems inner swing door is closed, thereby reaches the anti-pinch purpose.
Embodiment 3:
Cylinder outlet side sensor installation in drive system, when foreign matter occurring between near the side of doorframe and door-hinge in the inner swing door door-plate, the pressure of the cylinder outlet side in the drive system produces ANOMALOUS VARIATIONS, this signal of sensor acquisition, and give control system with this signal, control system is given the drive system signal, and the drive systems inner swing door is closed, thereby reaches the anti-pinch purpose.
Embodiment 4:
In the inner swinging door of passenger train control system, set the needed time range of the normal unlatching of inner swing door, when foreign matter occurring between near the side of doorframe and door-hinge in the inner swing door door-plate, inner swing door can't be finished normal unlatching, opening time surpasses the normal opening time of setting in the control system, control system detects this signal, thus the drive system of transmitting signals to, the drive system reverse drive, close inner swing door, thereby reach the anti-pinch purpose.
Claims (1)
1. method for preventing clamping during opening inner swinging door of passenger carriage, it is characterized in that utilizing sensor acquisition to the inner swing door off-note signal that opens the door and produce in the process, perhaps control system is directly gathered timeout signal, comes the control-driven system reverse drive by the inner swing door control system.
