Abstract
The utility model relates to an uninsulated pilot frequency type railway crossing automatic alarm, which comprises a signal generator, a crossing host computer and an alarm mechanism, wherein the crossing host computer comprises a signal receiving module, a control module and an alarm trigger module, and the signal receiving module and the alarm trigger module are both connected with the control module. Voltage with different frequencies generated by a signal generating module can be fed into a track circuit for facilitating the track circuit and the signal generator to form a return circuit, the state information of the track circuit is fed into the control module, the control module can send the information to the signal receiving module of the crossing host computer through a signal emitting module, a crossing host computer receiving module can transmit the signal to the control module, and the control module can drive the crossing alarm device to send out audible and visible alarm or no-alarm state through the alarm trigger module. The automatic alarm has the advantages that the alarm can realize the automatic monitoring and alarming, has high reliability and strong interference resistance capability, and can realize the overall monitoring, crossing railing interlocked control and intelligent management.
Description
Technical field
The utility model relates to a kind of autoalarm of level crossing, particularly a kind of naked alien frequencies sections way mouth autoalarm.
Background technology
The warning problem of level crossing mouth is a great problem of traffic safety always, especially smelter railway complexity, the crossing is many, this just gives and transports the hidden danger of bringing more eventful event safely, in order to guarantee safety, numerous level crossings all is provided with panalarm, as crossing gate or signal lamp, audible alarm etc., but traditional panalarm needs each road junction to set up a cover warning, and does not have monitoring, judgement on the whole, the function of execution.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, can realize automatic monitoring, warning, reliability height, jamproof naked alien frequencies sections way mouth autoalarm.
The utility model is achieved through the following technical solutions:
Naked alien frequencies sections way mouth autoalarm, this device is made up of signal generator, road junction main frame, alarm mechanism, signal generator is made of control module, signal emission module, signal generating module, the signal generating module link control module, and control module connects signal emission module; The road junction main frame is made up of signal receiving module, control module, alarm triggering module, and signal receiving module all is connected with control module with alarm triggering module;
The voltage that signal generating module is sent different frequency is sent into track circuit makes track circuit and signal generator form the loop, the status information of track circuit is sent into control module, and control module is sent to road junction host signal receiver module with this information by signal emission module; Road junction main frame receiver module passes to control module with this signal, and control module drives crossing alarm device by alarm triggering module and sends sound and light alarm or non-alarm condition.
The ranging coverage of described signal generator is 15-25m.
Compared with prior art, the utility model has the advantages that: can realize that automatic monitoring, warning, reliability height, antijamming capability are strong, can realize conduct monitoring at all levels, can realize crossing gate interlocked control and intelligent management.
Description of drawings
Fig. 1 is the structured flowchart of road junction main frame.
Fig. 2 is the structured flowchart of signal generator.
The specific embodiment
See Fig. 1, Fig. 2, naked alien frequencies sections way mouth autoalarm, this device is made up of signal generator, road junction main frame, alarm mechanism, see Fig. 2, signal generator is made of control module, signal emission module, signal generating module, the signal generating module link control module, control module connects signal emission module; See Fig. 1, the road junction main frame is made up of signal receiving module, control module, alarm triggering module, and signal receiving module all is connected with control module with alarm triggering module;
The voltage that signal generating module is sent different frequency is sent into track circuit makes track circuit and signal generator form the loop, the status information of track circuit (taking or idle condition) is sent into control module, and control module is sent to road junction host signal receiver module with this information by signal emission module; Road junction main frame receiver module passes to control module with this signal, and control module drives crossing alarm device by alarm triggering module and sends sound and light alarm or non-alarm condition.
The ranging coverage of signal generator is 15-25m.Signal generator sends the electric signal of different frequency to track, when train through out-of-date train wheel to causing the track circuit short circuit, the signal generating module of signal generator is sent signal and is given control module, and control module drive signal transmitter module is given the signal receiving module of road junction main frame.After the signal receiving module received signal of road junction main frame, pass to the road junction host computer control module, control module control alarm triggering module is sent sound and light alarm, and red light is flicker alternately.
When no train through out-of-date, when track circuit was idle, signal generator formed the loop with the whole rail circuit, at this moment, the road junction main frame receives the track circuit idle signal, control module is controlled alarm triggering module and is sent not alarm state information, Bai Dengliang.
