Abstract
The utility model belongs to field of vehicles, disclose a kind of screen door in rail transit obstacle detection system, comprise controller, piezo-resistance testing circuit, manual pull station, manual control panel are all connected with controller, and controller is also connected with train door with shield door by drive circuit.The piezo-resistance of described piezo-resistance testing circuit, be installed on continuously the back side of shield door, train door front apart from ground 500 ~ 1500 millimeters between region.Described manual pull station is installed on front, the reverse side of train door and shield door.The utility model is detected whether there being passenger between train and shield door by a kind of novel detection method, and can with other existing detection methods with the use of, effectively reduce the possibility that security incident occurs.
Description
Technical field
The utility model relates to a kind of screen door in rail transit obstacle detection system, belongs to technical field of transportation means.
Background technology
Along with the fast development in economy and city, the effect of track traffic in urban public transport system is increasing.In order to prevent personnel and article from falling into track, and reduce the operation energy consumption of air conditioner ventilating system in station, shield door installed by most of subway station.Although shield door serves in the subway station that passenger flow is larger avoid passenger because the crowded event falling rail occurs, but meanwhile because part passenger is about to rob when closing grab at train door, often cause and be sandwiched between shield door and subway train door, if be not found in time, subway train is once start, and passenger's life will not be protected.Although installation infrared line induction installation in subway system, similar event has occurred a lot of in Beijing and Shanghai subway, is extremely necessary to further improve subway shield door, to improve the security of subway shield door.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of screen door in rail transit obstacle detection system, avoids causing casualties because passenger is clipped between shield door and train door by shield door.
The purpose of this utility model is achieved through the following technical solutions:
Screen door in rail transit obstacle detection system, comprises controller, and piezo-resistance testing circuit, manual pull station, manual control panel are all connected with controller, and controller is also connected with train door with shield door by drive circuit.
Also comprise voltage-stabilized power supply, voltage-stabilized power supply is to system power supply.
The piezo-resistance of described piezo-resistance testing circuit, be installed on continuously the back side of shield door, train door front apart from ground 500-1500 millimeters between region, be the figure place of " cuboid adds fork " in Fig. 2 and Fig. 3.
Described manual pull station is installed on front, the reverse side of train door and shield door, is the figure place of " circle adds fork " in Fig. 2 and Fig. 3.
This system also comprises host computer, and controller is connected with host computer by communication interface, realizes being connected with other parts of subway communication system.
The utility model arranges piezo-resistance testing circuit, by piezo-resistance detected pressures, and the mechanical quantity of pressure is converted to electrical quantities, and is sent among controller.The spacing of general Train door and shield door is less, if someone is pressed from both sides wherein, shield door and car door can be subject to certain pressure, and had its natural reaction can push and shove train and shield door by folder passenger, more strengthen this pressure, we will detect altitude location 500mm---and 1500mm, effectively can detect by folder passenger, guarantee personal safety.
All manual pull station is installed additional at car door and shield door positive and negative, can button press by folder passenger, the passenger being in train or waiting hall also can button press, effectively increases system reliability.
Under normal circumstances, train normally runs; When piezo-resistance testing circuit being detected, because be subject to the extruding of passenger, two resistance values become large, when testing circuit electric current increases, this information is passed to controller, and controller judges whether this value is greater than setting threshold value, if be greater than, stop subway train operation, Train door reopens.When passenger pushes for emergency button, equally this information is passed to controller, Train door reopens.If generation systems false alarm, more then can by manual control panel's control system after confirming unmanned folder.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is shield door front schematic view, namely observes the schematic diagram of shield door from platform direction.
Fig. 3 is shield door reverse side schematic diagram, namely observes the schematic diagram of shield door from orbital direction.
Fig. 2, in 3, " square frame adds fork " place represents piezo-resistance, and " circle adds fork ", place represented manual pull station.In figure, solid line represents the article that side, place, visual angle shield door is installed, and dotted line is the article that visual angle offside shield door is installed.
Detailed description of the invention
As shown in Figure 1, screen door in rail transit obstacle detection system of the present utility model, comprise controller, piezo-resistance testing circuit, manual pull station, manual control panel are all connected with controller, and controller is also connected with train door with shield door by drive circuit.
Also comprise voltage-stabilized power supply, voltage-stabilized power supply is to system power supply.
This system also comprises host computer, and controller is connected with host computer by communication interface, realizes being connected with other parts of subway communication system.
Piezo-resistance testing circuit comprises the piezo-resistance of a series of continuous distributed, be installed on continuously the back side of shield door, train door front apart from ground 500-1500 millimeters between region.Manual pull station is installed on Train door and shield door front, reverse side.
As accompanying drawing 2, shown in 3, wherein piezo-resistance is installed on 500mm-1500mm place, guarantee can effectively detect by folder passenger, guarantees personal safety.
All manual pull station is installed additional at door outside and shield door positive and negative, can button press by folder passenger, the passenger being in train or waiting hall also can button press, effectively increases system reliability.
Under normal circumstances, train normally runs.
When piezo-resistance testing circuit being detected, because be subject to the extruding of passenger, two resistance values become large, when testing circuit electric current increases, this information is passed to controller, and controller judges whether this value is greater than setting threshold value, if be greater than, stop subway train operation, Train door reopens.
When passenger pushes for emergency button, equally this information is passed to controller, Train door reopens.
If generation systems false alarm, more then can by manual control panel's control system after confirming unmanned folder.
The related data of system can be uploaded to host computer by controller, is planned as a whole the carrying out practically state of adjustment System by host computer further.
