Track traffic signal fault calibration package
Technical field
The present invention relates to a kind of track traffic signal fault calibration package, the emergency communication adopting while being specifically related to a kind of track signal fault, location, correction, gate control system.
Background technology
Along with the fast-developing phase of urban track traffic, improving constantly of the running velocity of train, the continuous increase of passenger capacity, the kilometer of operation constantly extends, constantly a key factor that causes track traffic accident to take place frequently in this while train signal fault, and never have a set of complete calibration package in constantly increasing Rail Transit System stability aspect, also et out of order likely of stable system again, can not be by people's life in the accident as for any generation, in order to reduce the incidence of train accident, improving expeditious measures is the key issue of the good development of train.
Summary of the invention
Goal of the invention: a kind of track traffic signal fault calibration package is provided, to reduce the threat of signal fault to passenger's life, promotes the optimum fast development of track traffic.
Technical scheme: the present invention has taked following technical scheme:
Utilize Big Dipper positioning communication system to locate in real time train, the running distance between calculated column vehicle speed and any two cars.
Emergent traffic lights is a kind of light source warning cannot connect time of system signal et out of order and wireless signal, can provide necessary light source for tunnel, thereby guarantee being emotionally stable of passenger, avoids occurring that some are unnecessary flurried.
Utilize infrared tube that train stopping position is monitored and proofreaied and correct, guarantee that the relative position of Train door and platform is within error limit.
Increase the opening ways to Train door by circuit parallel, guarantee can evacuate passenger by timely opening car door after train has an accident, avoid the event of causing casualties.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
Train driving situation when holding on the whole signal fault generation source and occurring, locates train by the dipper system that utilizes China's independent research, in conjunction with Fig. 1, thereby grasps accurately train present position, and root
Go out the safety traffic distance between train average velociity and any two cars according to longitude and latitude and employing Time Calculation, once train generation signal accident causes control center cannot send corresponding order or successfully sends in the order situation that train crews cannot be received afterwards, understand in time the situation such as speed, position, relative distance of train driving by emergent Big Dipper positioning communication system, for the sufficient information of providing of accident is provided.
In tunnel, tend to occur the no signal situation of (comprising movable signal), in the time of system signal fault, cannot get in touch by wireless signal and train crews, the blindness operation of train can cause traffic accident, therefore the emergent traffic guidance system that distributes in tunnel is necessary, just at train ENTRANCE, traffic lights is not installed, be easy to like this cause train can not check in time car, thereby cause the generation of car accident.
Because huge passengers quantity is generally being born in track traffic, if the stop position of train has larger dislocation, can cause the crowded accident of trampling that easily causes of this station passenger getting on/off, also affect the normal operation of train.Proofread and correct necessary foundation is provided for train automatic train stop position at the infrared tube of train and installation location, track place use for this reason, in conjunction with Fig. 2, after train automatic train stop, train door allows to have certain error between station platform safety door, as shown in the figure, but exceed the state of connecting and closing according to infrared tube after the error of regulation and judge the stop position of train, groundly infraredly carry out communication by infrared on wireless mode and train.
The general mode of automatically opening that adopts of car door of train, the phenomenon that cannot open the door causing for anti-stop signal or fault, at gating circuit place, emergency circuit in parallel is independent of system signal, in the time of system signal et out of order, also there will not be the phenomenon that can only open Door by Hand or cannot open the door, provide safeguard for evacuating in time passenger.
Track train signal fault calibration package as shown in Figure 3, comprises Big Dipper positioning communication system, the emergent guiding of traffic lamp system in tunnel, parking locating calibration system, emergent door control system.
