Description

A kind of bus controllable safety window automatically turns on method
Technical field
The present invention relates to public transport field, more particularly, to a kind of bus controllable safety window automatically turns on method.
Background technology
Hinged bus (mounting bus): some buses can increase length and handling capacity of passengers with two section vehicle bodies, and saves car two Telescopic bonding station (part of plugging between similar train car card) is added with assisted diversion between body.These buses are referred to as hanging Connect bus, rather prevailing in North America various places.China's Mainland claims " articulator ", " passage car " or " giant dragon (car) ".In BeiJing, China Etc. ground once very common, but this is rarer in Taiwan.20th century the mid-80, Shenyang Passenger Automobile Factory produced the whole of China First " double hinged bus ", trade mark is China's dragon board, long 23 meters, and has carried out volume production, once in Shenyang, a plurality of public bus network in Dalian Upper life-time service.European Producers more produced " double mounting bus ", " double-deck mounting bus " etc. in recent years;Whole world bar the longest Scholar -- in Brazil's walking, long 26.8 meters of Volvo (Hong Kong " Volvo " is called " rich and powerful people ") b12m bus, it is one pair Mounting bus.
Low land platform bus (accessible people with disability's bus): start low land platform bus prevailing, compartment ground in latter stage in 20th century Platform and does not set step than old money bus closer to road surface.Full car low land platform be referred to as low-floor bus, and later half compartment has Two or three steps and first half compartment low-floor be referred to as low entry bus.These buses are equipped with facility to facilitate handicapped taking advantage of Objective (such as taking advantage of wheelchair-bound personage), and fall the required time on shortening.In Hong Kong, low land platform bus is very common.Hong Kong Nine bars take the lead in introducing low land platform bus.With the increase in demand to accessible transport for Hong Kong society, add that new airport enables, government Require Ge Jian bus firms with low land platform bus server field wire.Since then, so Hong Kong bus firms all only can purchase ring Protect low land platform bus.And in China's Mainland, the accessible bus of low-floor is still more rare.
Personal safety in order to protect passenger on public transport is inviolable, and property is not suffered a loss, and the safety door of buses is usual There are built-in lock device or bolt device, in bus running or in Public Transit Bus Stopping, built-in lock device or bolt device closed, Avoid offender to pull open safety door entrance vehicle from car and carry out criminal behavior, and when danger, passenger on public transport can With manual unlocking built-in lock device or bolt device, thus opening safety door escape.
Typically, however, passenger on public transport is without special safety training, and do not know about the safety door of buses and also have There are built-in lock device or bolt device, at this moment, if buses there occurs fire disaster accident, passenger is because built-in lock dress cannot be opened Put or bolt device and safety door cannot be opened, can only be gathered in around safety door, delay the escape time of passenger, easily make Become to cause the accident of excessive passenger's injures and deaths.
Meanwhile, buses safety protection equipment automatization level of the prior art is not high, and such as vehicle window is difficult to quickly beat Open, Security mechanism work efficiency is low, and the precision of vehicle equipment for danger detection, quantity and type are all Can not meet the demand of passenger's escape, cause buses class of safety protection to maintain a relatively low horizontal line position.
Accordingly, it would be desirable to a kind of new buses security protection scheme, can in the case of finding more suspect, The built-in lock device of self-closing safety door or bolt device, can automatically open up peace in the case of finding vehicle abnormality state The built-in lock device of air cock or bolt device, are also upgraded to the security protection system of vehicle and have been transformed.
Content of the invention
In order to solve the above problems, the invention provides a kind of bus controllable safety window automatic opening system, to security window Carry out structure updating can quickly open when ensureing and danger occurring, introduce car outer suspect's testing equipment and car external environment is carried out Detection, determines whether built-in lock device or the bolt device of self-closing safety door, the people of protection occupant based on testing result Body safety, also optimizes safety protective system for vehicle simultaneously, to automatically open up the dark of safety door when finding vehicle abnormality state Locking device or bolt device, prevent the situation that passenger cannot escape because of being difficult to open safety door from occurring.
