Description
Technical field
The present invention relates to a kind of subway safe door self checking method, and in particular to after a kind of subway safe door is locked it is secondary from
Detecting method.
Background technology
Traditional subway safe door can only install a kind of safety shutdown self-inspection facility, its for some than relatively thin medium, than
Sensing capability such as to clothing or hair is inadequate, or without sensing capability.When the clothing or hair of Metro Passenger are by subway
Door is when clamp, and passenger has to can just be rescued when waiting next stop enabling, and such case is likely to cause more serious
Accident occurs.
In order to preferably ensure the personal safety of Metro Passenger, can prevent ground by installing multiple laser sensors
Iron safety door clamp people's event, but when subway safe door completely close and it is locked when, current this safety measure is substantially just
Through failing.
In consideration of it, proposing a kind of subway safe door self checking method, two can be carried out in closing process to subway safe door
Secondary detection is the problem to be studied of the invention.
The content of the invention
Regarding to the issue above, it is an object of the invention to provide a kind of subway safe door self checking method, it is intended to solve due to
Current subway safe door can not detect the frivolous objects such as clothing, the hair clamped, and jeopardize the problem of passenger's personal safety.
To achieve these goals, the present invention uses following technical scheme：A kind of subway safe door self checking method, takes in advance
A self-inspection platform is built, the self-inspection platform includes laser emitting module, laser detection module, laser mirror, microprocessor, number
According to sending module and data reception module；The laser emitting module, laser detection module, data transmission blocks, data connect
Receive module to be connected with microprocessor respectively, the laser mirror is installed on the door of the fan door of subway safe door two along upper, the door
Along the relative edge of as subway safe door two fan door；The laser emitting module is installed on the upper end on subway safety door edge,
The laser detection module is installed on the lower end on the door edge of subway safe door；
When in use, during subway safe door normal switching-off, the laser that laser emitting module is launched can be by being installed on
Subway safety door is reached in laser detection module along after upper laser mirror M secondary reflections, and M depends on being installed on metro safety
Angle a, metro safeties of the Men Men along the direction and subway safety door of upper laser emitting module transmitting laser between
The height H and metro safety of door are installed on two fan safety doors door along the distance between upper laser mirror W when closing, wherein
Relation between four meets formula (M+1) * W=H*tana；
When subway safety door latch is dead, before subway will start, the vehicle control syetem of subway sends instructions to data
Receiver module, data reception module sends an instruction to microprocessor, subway safe door is initially entered secondary self-inspection flow；It is micro-
Processor control laser emitting module transmitting beam of laser, laser detection module starts simultaneously at detection laser, and by testing result
It is sent to microprocessor；Whether microprocessor judges there is foreign matter between subway safe door according to the testing result, and will sentence
The vehicle control syetem that result is sent to subway by data transmission blocks is determined, so that it carries out postorder control action.
As a further improvement on the present invention, the safety door self checking method has self error detection capability again, local
Before iron is stopped transport or started shipment, self error detection is carried out by sending instructions to microprocessor, make the subway safe door certainly
Detecting method it is determined that in the case of there is no foreign matter between subway safe door run, if the subway safe door self checking method detect
To there is foreign matter, then microprocessor sends out the information for itself having broken down by data transmission blocks.
As a further improvement on the present invention, the laser mirror has minute surface protection device, is in subway safe door
During open mode, minute surface protection device can cover laser mirror, in case the minute surface of laser mirror is damaged, cause describedly
The situation that detection mistake occurs in iron safety door self checking method occurs；When metro safety will be closed, minute surface protection device can be certainly
It is dynamic to open, enable laser mirror regular reflection laser.
As a further improvement on the present invention, between the angle value of a is spent 0 to 90, and the bigger M values of a values are also more
Greatly, the safety door can be detected foreign matter size also just it is smaller.
As a further improvement on the present invention, the laser that the laser emitting module is launched has certain switching frequency
F, when the switching frequency that laser detection module is detected is the laser of f, is just judged to have been detected by laser.
As a further improvement on the present invention, the subway safe door self checking method also includes a kind of by particular design
Subway safe door, the door edge of the subway safe door by particular design is concave structure, and the laser mirror is installed on
In the middle of the concave structure, when subway safe door is closed, can be kept at a distance between the laser mirror that two fans door can be made
W。
As a further improvement on the present invention, the laser that the laser emitting module is launched is the shorter laser of wavelength,
Such as violet laser or ultraviolet laser, this kind of laser can not penetrate tulle or some other translucent medium.
As a further improvement on the present invention, the subway safe door self checking method also includes alarm module, the alarm
Module is connected with microprocessor, when there is foreign matter between the subway safe door self checking method detects safety door, mould of alarming
Block first sends alarm sound, and remind near safety door has foreign matter and wait the of short duration time to make passenger voluntarily locate in passenger safety door
Reason；If the stand-by period terminates, the subway safe door self checking method judges foreign matter is still present in safety door, then sends out and sentences
Determine result.
As a further improvement on the present invention, the concave structure is built with a kind of photo-sensitive cell, the photo-sensitive cell with
Microprocessor is connected, and when subway safe door is closed, the outside intensity signal that photo-sensitive cell starts to sense is sent to micro- place
Reason device, microprocessor judges whether metro safety can close closely according to intensity signal.
Operation principle of the present invention and effect are as follows：
The present invention relates to a kind of subway safe door self checking method, a self-inspection platform is built in advance, including laser emitting module,
Laser detection module, laser mirror, microprocessor, data transmission blocks and data reception module；Laser mirror is installed
