Abstract
The invention discloses a pedestrian crossing safety device. When a signal lamp of a pedestrian crossing is green, a lock is opened, pedestrians crossing the pedestrian crossing take out a colored flag such as a green flag from a hole 3 of a lamp pole 2, and the pedestrians cross the pedestrian crossing with the flag in hand. When a driver of a turning car sees the pedestrians with the green flags in hand, the driver knows that the signal lamp is green and then parks. After the pedestrians cross the pedestrian crossing, the pedestrians insert the flags in a hole 3 of an opposite lamp pole 2. When the signal lamp of the pedestrian crossing is red, the flags are locked in the holes by the lock, pedestrians can not take the flags out of the holes, and therefore the pedestrians can not cross a street rashly.
Description
Technical field
The present invention relates to the cross walk safety device.
Background technology
Cross walk relies on traffic lights to guarantee traffic safety usually.But the situation that people's car passes through cross walk simultaneously still always occurs in practice, and often therefore cause dangerous situation.The technical scheme that solves the cross walk safety problem has a lot.ZL200820119094.4 Chinese utility model patent for example, it discloses a kind of Crosswalk warning board.The technical scheme that this patent adopts is to utilize flashing lamp to make the signal lamp at cross walk place more eye-catching.ZL201120155466.0 Chinese utility model patent and KR19980022414 korean patent application are warned the pedestrian who passes through cross walk violating the regulations by warning system.The scheme of No. 200420150519.X Chinese utility model of ZL is horizontal bar to be set at the cross walk place prevent that pedestrians disobeying traffic rule from walking.These schemes all lay particular emphasis on the management to the pedestrian.Yet we find, turning vehicle is a more serious problem and danger at the row of robbing at cross walk place.This turning vehicle rob row, part is to allow the traffic rules of keeping straight on because the driver has ignored to turn, and is that the position due to the traffic lights at cross walk place makes the driver be difficult to see on the other hand.
Summary of the invention
The present invention aims to provide a kind of cross walk safety device, it not only can reduce the possibility that pedestrians disobeying traffic rule passes through, simultaneously also can remind turning vehicle and dodge in the situation that cross walk gives a green light the pedestrian who normally passes through, thereby greatly reduce the danger at cross walk place.
Have the cross walk traffic lights according to cross walk safety device of the present invention, on the roadside by this cross walk, fixedly contents are set, when it can be red light at the traffic lights of cross walk, a kind of caution article are held within it with locking, and release when the traffic lights of cross walk are green light, make described caution article to take out, carry when walking cross walk for the pedestrian, thereby prompting vehicle driver, this moment, the cross walk green light was bright, the pedestrian has right of way, and vehicle should be dodged.
Carrying the caution article when crossing the street due to the pedestrian, the driver of turning vehicle learns that just the traffic lights of cross walk this moment are green light, dodges the pedestrian of right of way thereby stop.Moreover, and also easily judge the responsible party when traffic accident appears in cross walk.That is, the pedestrian who passes through on cross walk have the people hand-held during described caution article, if there is the Vehicular impact pedestrian, must be that vehicle driver's all responsibility is violating the regulations.Otherwise, if when vehicle bumps against the pedestrian, there is no the pedestrian of hand-held described caution article on cross walk, be probably pedestrian running red light.
Preferably, described cross walk safety device also are furnished with camera.This camera preferably can photograph whole cross walk simultaneously.The camera that such layout has been arranged, the situation of cross walk in the time of just can the judgement accident occurs after the traffic accident, namely, according to whether have on cross walk carry the caution article the pedestrian can find out that traffic lights at that time are red light or green light, thereby be conducive to analyze the responsibility of traffic accident.
Described fixedly contents can be a container in roadside, the caution article can only be put into when its lid is arranged to red light, can not take out, and can take out when green light.But preferably, described fixedly contents are arranged on the lamp stand of traffic lights, can save like this space-efficient and take.
Described caution article can have the selection of various ways, are for example club or pan, but in above-mentioned arbitrary scheme preferably, described caution article are the little flag with conspicuous color.Although supporting described fixedly contents can have multiple choices in this case, preferably, the traffic signals lamp stand is provided with the hole of the flagpole that can insert these little flags.
The lockset of the locking caution article in described fixedly contents can adopt various ways.For the traffic lights that timing is controlled, lockset can adopt the timing of synchronizeing with traffic lights to control, and also can be controlled by the changeover switch of traffic lights.
Preferably, described lockset is electromagnetic lock in above-mentioned arbitrary scheme.This is a scheme that relatively easily realizes.Yet the present invention does not get rid of any other applicable scheme, light-operated lock for example, the perhaps lockset of clock control etc.
If the caution article are little flag, preferably, to be with flutedly on the flagpole of described little flag, described lockset has the dead bolt that can extend in described groove.Preferably, the upper surface at least of described dead bolt is wedge shape in this scheme.More preferably, up and down two shows and is wedge shape.In this preferred version, the permission of dead bolt lengthwise movement and forbid that mechanism configures like this, it makes dead bolt can freely do lengthwise movement under green light phase, and under red light phase, only have when dead bolt top is under pressure, when namely inserting flagpole, dead bolt just can lengthwise movement, and when being under pressure below dead bolt, can not do lengthwise movement.So just, in the time of can forbidding red light, flagpole is pulled out, but at this moment flagpole still can insert hole.Skilled person in the art will appreciate that a lot of modes can realize this scheme.For example, be provided with a contact switch in the bottom of the root of the tongue annex of dead bolt, it controls the stop part of the lengthwise movement of dead bolt.Extract little flag when having the people to want at red light, the soffit of dead bolt is subject to power upwards, and by leverage, the dead bolt root is subject to downward power, and described contact switch is pressed, and described stop part backstop is lived dead bolt, makes it can not lengthwise movement.If but at this moment want to insert chess piece, and the upper surface of dead bolt is subject to downward pressure, and the root of dead bolt does not have downward pressure, and described contact switch does not stress, and dead bolt can lengthwise movement, thus little flag can insert hole.
A kind of easier replacement form of implementation is, the bottom of flagpole, and for example the bottom is provided with larger-diameter projection.In this form of implementation, dead bolt also can be simply, and needing only upper surface is wedge shape.
Described little flag can adopt any applicable mode to point out the driver, for example by text prompt, perhaps points out by pattern, for example the pattern of pedestrian's street crossing.
Preferably, described caution article are local with reflective or fluorescence at least in above-mentioned arbitrary scheme, thus daytime or all easily found by the driver night.
Preferably, described cross walk safety device are with control system; This system comprises host computer, slave computer, and realizes data communication between slave computer and host computer by the RS-232 serial communication interface.For example, when stop-light is green light, host computer sends synchronous indicating signal to slave computer, slave computer receives the described synchronous indicating signal that described host computer sends when green light after, to the power driving circuit output signal, this power driving circuit makes the normal open switch of relay closed then to the relay output drive signal, the resistance that calutron work, caution thing overcome calutron takes out from the hole on lamp stand.
When traffic lights were redness, host computer sent synchronous indicating signal to slave computer, after slave computer receives red signal, the relay normally open switch keeps, and calutron is not worked, at this moment, if the caution thing is arranged in the hole of lamp stand, this caution thing can not be extracted from hole; When not warning thing in hole, allow the caution thing to insert in hole.
When calutron is worked, collect the electric current that flows through calutron by sample circuit, and its sample rate current is converted to be input in comparator after voltage signal compares with reference voltage, when the sample rate current signal was normal, it is working properly to determine calutron to slave computer that comparator sends normal signal instruction (high level signal); When the sample rate current signal was undesired, comparator sent fault-signal (low level signal) to slave computer, after slave computer is received fault-signal, sends alarm signal by warning circuit.
