Abstract
The utility model discloses a closed loop feedback signal device which comprises a scheduling system (1), a signal device controller (2), a signal lamp (3), a light ray detector (4) and a sensor (5). The scheduling system (1) is used for sending a scheduling signal to the signal device controller (2) through an optical fiber; the signal device controller (2) is used for controlling the igniting, flickering or extinguishing of the signal lamp (3) according to the scheduling signal; the light ray detector (4) is used for detecting the light rays of the signal lamp (3) and transmitting the light rays to the sensor (5) through an optical fiber; the sensor (5) is used for converting the intensity, color and flickering frequency of a colored optical signal into an electrical signal to form a fed-back scheduling instruction and inputting the fed-back scheduling instruction to the scheduling system (1); and the scheduling system (1) is further used for comparing the sent scheduling instruction and the fed-back scheduling instruction to judge that whether the closed loop feedback signal device works normally or not. In the utility model, the scheduling instruction is fed back in a closed loop, the timeliness is high, and the operation failure of the closed loop feedback signal device can be judged in time. In addition, because the signal transmission is the optical signal transmission, the interference can be avoided, and the reliability of the closed loop feedback signal device can be improved.
Description
Technical field
The utility model relates to a kind of teleseme that can carry out the fault detect of light feedback to signal lamp.
Background technology
One Chinese patent application CN201010107105.9 discloses a kind of testing system for optical feedback faults of signal lamp terminal, and it comprises: light collection unit, the light signal of acquired signal lamp output; The optical signal transmission unit, with the optical signal transmission that collects to photoelectric conversion module; Photoelectric conversion module converts the light signal that receives to electric signal, transfers to the judgement that the teleseme controller carries out the signal lamp running status.Photoelectric detecting technology is adopted in this patented claim; Light on and off situation according to signal lamp is judged the ruuning situation that signal lamp is current; To realize accurate, reliable detection, can overcome the traditional detection scheme thus because the erroneous judgement phenomenon that problems such as external circuit electric leakage cause to the signal lamp operation troubles.But because this testing system for optical feedback faults of signal lamp terminal detection signal lamp operation troubles and dispatch command are not synchronous respective operations, the detection of scheduling signals is ageing not high, can't in time judge the signal lamp operation troubles.In addition, because the electric signal transmission is vulnerable to interference, so the reliability of said system is also lower.
The utility model content
The utility model technical issues that need to address are to provide a kind of dispatch command to form close-loop feedback, can in time judge the signal lamp operation troubles, are difficult for being interfered the close-loop feedback teleseme that reliability is high.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: the close-loop feedback teleseme; Comprise dispatching system, teleseme controller, signal lamp, light detectors and sensor; Described dispatching system is sent scheduling signals through optical fiber and is given the teleseme controller; The teleseme controller comes lighting, glimmer or extinguishing of control signal lamp according to scheduling signals, the light situation of light detectors detectable signal lamp, and light is passed through Optical Fiber Transmission give sensor; Sensor converts coloured light signal intensity, color and flicker frequency to electric signal to form the dispatch command that feeds back and to input to dispatching system, and the dispatch command that dispatching system is relatively sent and the dispatch command of feedback are to judge whether teleseme is in proper working order.
Described light detectors is the coloured light detecting head that places the other band GRIN Lens of signal lamp filament.
Described light detectors is the camera that places the other band GRIN Lens of signal lamp filament.
Owing to adopted above-mentioned structure, the dispatch command that the dispatching system of the utility model can relatively be sent and the dispatch command of feedback are in the time-delay of regulation; If the dispatch command of dispatch command that sends and feedback is consistent, teleseme is in proper working order, otherwise early warning; Take the early warning scheme; Launch the space signal machine, send maintenance instructions, the generation of preventing accident.The dispatch command of the utility model forms close-loop feedback, and ageing height can in time be judged the signal lamp operation troubles.In addition,, can avoid being interfered, improve the reliability of teleseme because signals transmission has adopted above-mentioned light signal.
Description of drawings
Fig. 1 is the frame diagram of close-loop feedback teleseme.
Embodiment
Be described in further detail below in conjunction with the embodiment of accompanying drawing the utility model.As shown in Figure 1, the described close-loop feedback teleseme of the utility model comprises dispatching system 1, teleseme controller 2, signal lamp 3, light detectors 4 and sensor 5.Described dispatching system 1 transmits scheduling signals through optical fiber link and gives teleseme controller 2.Teleseme controller 2 comes lighting, glimmer or extinguishing of control signal lamp 3 according to scheduling signals.Described light detectors 4 is the coloured light detecting heads that place the other band GRIN Lens of signal lamp 3 filaments, and described light detectors 4 also can be the camera that places the other band GRIN Lens of signal lamp 3 filaments.The light situation of described light detectors 4 detectable signal lamps 3; And light is passed through Optical Fiber Transmission give sensor 5; Sensor 5 converts coloured light signal intensity, color and flicker frequency to electric signal to form the dispatch command that feeds back and to input to dispatching system 1, and the dispatch command that dispatching system 1 is relatively sent and the dispatch command of feedback are to judge whether teleseme is in proper working order.
When the utility model was specifically worked, the dispatch command that dispatching system 1 is sent sent teleseme controller 2 to through optical fiber link, and teleseme controller 2 is lighted, glimmered or extinguish according to dispatch command control signal lamp 3; In optical fiber, optical fiber imports coloured light the color sensor 5 of control room into to light detectors 4 with the coloured light signal focus, and color sensor 5 converts coloured light signal intensity, color and flicker frequency to electric signal in the control room; Converting digital signal into through A/D, digital signal converts logical signal to, converts the dispatch command of feedback again into; Input scheduling system 1, the dispatch command of the feedback that dispatch command that dispatching system 1 is relatively sent and teleseme feedback signal convert to is in the time-delay of regulation; If the dispatch command of dispatch command that sends and feedback is consistent, teleseme is in proper working order, otherwise early warning; Take the early warning scheme; Launch the space signal machine, send maintenance instructions, the generation of preventing accident.
The coloured light detecting head or the camera position of above-mentioned band GRIN Lens are fixed; Major-minor filament position in lamp is different, the diverse location of the focal plane of amasthenic lens of living in, and the light intensity after the focusing is different; Signal after conversions such as color sensor is different; Judge it is main filament or auxiliary filament work according to the light intensity signal of correspondence, if the teleseme maintenance instructions is sent in auxiliary filament work immediately.
In a word; The above-mentioned preferred implementation though the utility model has been given an example; But should explain; Though those skilled in the art can carry out various variations and remodeling,, otherwise all should be included in the protection domain of the utility model only if such variation and remodeling have departed from the scope of the utility model.
