Description
Technical field
The present invention relates to safety door control field, particularly relate to a kind of safety door for bus automatic control platform.
Background technology
Safety hammer is typically mounted at vehicle window side.During use, the toe of safety hammer to be used, center of glass of fiercelying attack position, when
When glass is pounded out a duck eye, glass a little will ftracture to surrounding from being tapped.At this moment passenger needs to catch arm supports in car
Health, and firmly the broken glass driven is kicked out outside car with sole, then escaping from window.Safety hammer is used to draw " ten " word on glass
After pound again, window efficiency can be improved brokenly.
It addition, sunroofs also can emergency escape.After bus is on fire, the natural reaction of passenger is to escape from car door, but
Accident generation tail gate is likely to cannot be normally-open, and sunroofs is the another important channel that passenger escapes.
Being furnished with fire extinguisher in bus, position is typically in the middle of driver's seat rear portion and vehicle body.When bus is on fire, first
See condition of a fire size.If degree on fire is the lowest, driver and conductor should use vehicle-mounted fire extinguisher to extinguish the blaze immediately.If the intensity of a fire is relatively
Greatly, when driver and conductor can not solve, PLEASE CALL US IMMEDIATELY ON the emergency of fire-fighting rescue platform phone.
Having manual rotary switch near car door, after general bus door is fastened, driver does not opens the door, and passenger cannot get off,
Running into fire occurs the rotary valve of twisting " door bag manual rotary switch ", cannot open the door once driver, and passenger is rotatable to open
Close, firmly push and can open car door.
Each car has emergency button, and some is by driver's seat, and some is at car door top, and shape is mostly as the shelves of electric fan
Bit switch, this switch mainly cuts off gas circuit.And the mode opened is the most different, concrete operations are typically by emergency button
It is illustrated.
General bus roof has two emergency exits, and a lot of people are easily considered vent its mistake.Escape window
There is button above, whole for vehicle window toward extrapolation after rotation.Especially vehicle rollover when, this escape window is highly useful.
But, for being loaded with the bus of full passenger, existing vehicle sensory equipment and emergency reaction equipment
Quantity and type can not meet the demand of passenger, current emergency reaction equipment remains a need for too much artificial participation process, nothing
Method is reacted voluntarily according to vehicle concrete condition, this substantially prolongs the emergency reaction time of passenger, causes the safety of vehicle
The significantly decline of degree of protection, easily causes the generation of major casualties.
Accordingly, it would be desirable to a kind of new bus protectiving scheme, it is possible to existing vehicle structure is transformed, to existing
Emergency reaction equipment carry out automatic updating, the most also number of sensors and kind to vehicle abnormality state-detection and increase
Many such that it is able to the abnormalities such as fire to be detected in time and make a response rapidly, it is to avoid loss extension.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of safety door for bus automatic control platform, introduce multiple

Accompanying drawing explanation
Below with reference to accompanying drawing, embodiment of the present invention are described, wherein:
Fig. 1 is the block diagram according to the safety door for bus automatic control platform shown in embodiment of the present invention.
Reference: 1AVR32 chip；2 emergency speech playback equipments；3 pump control apparatus
Detailed description of the invention
Below with reference to accompanying drawings the embodiment of the safety door for bus automatic control platform of the present invention is carried out in detail
Explanation.
Bus is huge to social influence, and urban development plays most basic impetus.Bus makes city
The people experience the most unprecedented close, also shorten the distance between city and neighbouring villages and small towns, contact frequently.
The origin of public transport at least can trace back to 1826.Retired officer was at the Nan Te of the France northwestward at that time
(Nantes) flour milling mill is founded in suburbs, and the hot water discharged by steam engine is had a bath for people and built public outdoor bathing place, and provides the city that plugs into
The carriage service at center.When he finds that people on the way can use his stage carriage, just found hotel of shuttling back and forth
Between passenger vehicle route, allow passenger and mail in the most freely using.
Paris is the leading city of bus, and London is followed by.On July 4th, 1829, Englishman George
The bus (Omnibus) of Shillibeer comes across street corner, London, comes and goes Bai Ding along newly-built " new road " (New Road)
Paddington and bank area, stop over Yorkshire Yorkshire Stingo, every day 4 classes of each direction.Less than 10 years, this
One service France, Britain and each big city of U.S.'s east bank (such as Paris, Lyons, London, New York) are popularized.
Bus is that the people of trip provide many convenient, is the walking-replacing tools commonly used of people, but he carries for us
While convenient, the most under cover " murderous intention ".Recently, there are the relevant informations such as much, spontaneous combustions the most on fire about bus, blast
Report, these people increasingly pay close attention to the safety problem on bus, except helping the escape that bus rider association is correct
Outside self-rescue method, in addition it is also necessary to transform existing bus arrangement, increase more safety protection equipment, improve existing tightly
First aid protection mechanism, thus save oneself the more aid of offer and passway for escaping for the escape of passenger.
In prior art, the highest for the sensor device precision of vehicle-state abnormality detection in bus, type and
Negligible amounts, the safety protection equipment kind of bus is few, it is impossible to meets passenger under full state and sets security protection
Standby demand, safety protection equipment remains a need for passenger's naked eyes and finds its position, and the operation of safety protection equipment needs completely
Passenger is accomplished manually, and its automatization level is low, and work efficiency is low, and to reflecting the requirement of speed very when bus meets accident
Height, accident casualty quantity is often depending on the speed that enables of safety protection equipment, and safety protection equipment of the prior art is the brightest
Aobvious be unable to reach it is intended that work efficiency.
In order to overcome above-mentioned deficiency, the present invention has built a kind of safety door for bus automatic control platform, by increasing capacitance it is possible to increase
For the type of sensor device and the quantity of vehicle-state abnormality detection, increase simultaneously vehicle safety equipment type and
Quantity, additionally it is possible to substitute existing manual operation pattern with automatic operation mode, accelerates the reflection speed of vehicle safety equipment
Degree, thus facilitate the fast-escape of passenger inside the vehicle.
