Description
Technical field
The utility model relates to subway panalarm technical field, and especially a kind of novel subway platform is waited warning.
Background technology
Now, Construction of Urban Rail Traffic is greatly developed in all parts of the country, and urban track traffic relies on the distinguishing features such as its speed is fast, freight volume large, safety is punctual, protection of the environment, economize energy and land used to become the main travel modal of people gradually.But there is certain security risk in metro operation, the air pressure such as the produced during vehicle pull-in passenger that likely will wait is with people's track accidents caused, the reason of accident is the awareness of safety problem of passenger self on the one hand, is that some station does not arrange spacer assembly on the other hand." the subway platform safety system of unshielded door " just arises at the historic moment.It is a kind of by the most direct mode reminding passengers stopping hazardous act, sends the equipment of dangerous situation prompting to platform staff simultaneously.At the station of unshielded door, when passenger steps in safe yellow line, this system very first time gives a warning, and prevents trouble before it happens, thus ensures the inherently safe of passenger and the safe operation of train.
At present, do not have safety control in the subway line of shielded gate in urgent need to be improved at some.Therefore, design a can very first time reminding passengers and the safety-conscious system of platform staff particularly important.Therefore, be necessary to design a kind of good stability, the platform that accuracy of detection is high is waited warning.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of structure is simple, stability is high novel subway platform to wait warning.
To achieve these goals, the utility model adopts following technical scheme:
A kind of novel subway platform is waited warning, it comprises signal projector, signal receiver, signal processing module and alarm module, the optical signal that described signal projector is launched is through taking precautions against district's arriving signal receptor, described signal receiver sends signal processing module to after optical signal is converted to electric signal, and described signal processing module controls the action of alarm module according to the change of the signal received.
Preferably, described signal projector and signal receiver are located in the same horizontal plane and are symmetrical up and down.
Preferably, described signal projector and signal receiver are active infra-red sensor.
Preferably, described signal processing module comprises AT89C51 micro controller system.
Preferably, described alarm module comprises voice alarm module and LED lamplight alarm module.
Owing to have employed such scheme, the utility model adopts infrared pickoff to respond to as detection, and carries out signal transacting by AT89C51 micro controller system, to when having passenger's monitoring range, starts voice alarm module and LED lamplight alarm module is reported to the police; Infrared induction device can not cause radiation injury to human body, and structure is simply very easily installed, good stability, has very strong practicality.
Accompanying drawing explanation
Fig. 1 is the system architecture diagram of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, a kind of novel subway platform of the present embodiment is waited warning, it comprises signal projector 1, signal receiver 2, signal processing module 3 and alarm module 4, the optical signal that signal projector 1 is launched is through taking precautions against district's arriving signal receptor 2, signal receiver 2 sends signal processing module 3 to after optical signal is converted to electric signal, and signal processing module 3 controls the action of alarm module 4 according to the change of the signal received.
Signal projector 1 and signal receiver 2 are active infra-red sensor, and are symmetrical arranged up and down in same level.There is the factors such as curve platform according to the distance of reaction of infrared induction device and subway platform, this infrared induction device is vertical type sensing, below the yellow safety line bottom and top ceiling of unshielded door platform, lay corresponding infrared induction device respectively.The infrared ray launched by signal projector 1, through taking precautions against district's arriving signal receptor 2, constitutes a barrier line.When the passenger's body of waiting that platform is a bit of steps in safe yellow line zone, infrared beam is blocked, and signal receiver 2 receives the infrared signal of change and sent to signal processing module 3.Signal processing module 3 receives this electric signal, indicates the alerting signal that the alarm module 4 comprising voice alarm module and LED lamplight alarm module sends after amplifying and suitably processing.The prompting passenger that waits takes care, and notifies that station affair staff notices that the platform situation of responsible section prevents the generation of Peril Incident.
In metro operation process, before train comes to a complete stop and Train door close after circuit system close, system is in running order protects passenger safety; After train arrival comes to a complete stop, circuit disconnects automatically, and system is closed automatically.When system works, when there being people to enter the monitoring range of infrared pickoff, sensor can produce corresponding electric signal, is amplified, compare and after exclusive PCR, result be sent to alarm module 4 by AT89C51 system.Alarm module 4 is started working, and sound and light alarm prompting will continue ten seconds.If after this still have people in monitoring range, alerting signal will produce again, until passenger leaves hazardous location.
Signal processing module 3 is cores of the present embodiment IR alarm system, the minimum system that it is made up of AT89C51 micro controller system, reset circuit, crystal oscillator etc.Speech chip in voice alarm module adopts I SD4004 speech chip, after passenger crosses catch siding triggering alarm system, loudspeaker is by automatic speech prompting: " going back in catch siding ", this speech chip can truly, reproducing speech and effect sound naturally, avoid general solid recording circuit and quantize and compress the quantizing noise and metallic sound that cause.LED lamplight alarm module by 4 light-emitting diodes be fixed on banded FPC connects resistance after connect the pin of the RXD of micro controller system, and external VCC, after the RXD pin of micro controller system is set to low level, light-emitting diode is lit, and plays the effect of reminding passengers and terminal attendant.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
