The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a circuit block diagram of the present utility model;
Fig. 2 is the installation site synoptic diagram of the utility model sensor, and wherein 1 is the stagger sensor, and 2 is vibration impact transducer, and 3 are contact wire, and 4 is pantograph.
Embodiment
Referring to Fig. 1, Fig. 2, design and installation is in the various electric locomotive of operation at present.Its major function comprises: the 1. automatic detection that the contact wire stagger is transfinited; 2. the suffered hard spot of pantograph is impacted the automatic detection of transfiniting; 3. realize real time monitoring to the bow net state.When surpassing, the contact wire stagger sets the limit, or the suffered hard spot impact acceleration of pantograph surpasses when setting the limit, bow net system state monitoring device will write down and the storage failure dot information automatically, and in the electric locomotive operational process, the bow net state is monitored in real time, pinpoint the problems and can in time take measures, the accident that prevents further enlarges.Stagger sensor 1 and the vibratory impulse detecting sensor 2 that transfinites is installed on the pantograph collector head, and the receiver of infrared camera, height voltage isolation signal transmitting apparatus is positioned at the low voltage side of roof; Image acquisition circuit is installed near the interior main frame that carries out the electric part fault diagnosis of locomotive.When sensor when contact wire stagger or hard spot transfinite, fault-signal is converted to modulated light signal through the transmitter of signal transmission passage and outwards launches, the receiver that is positioned at low voltage side is converted to corresponding electric signal again with the light signal that receives, by the pantograph and catenary fault information acquisition in the cab and diagnostic device record and storage failure dot information.Consider also can observe in real time bow net picture clearly when locomotive travels in night and tunnel, camera is selected infrared camera for use.The video output signals of camera is delivered to indoor monitor of trainman and main frame simultaneously.
Stagger sensor 1 adopts infrared type diffusion reflection pattern optoelectronic switch, optical source wavelength λ=880nm, working current 30mA, response time 3ms, when contact wire from the distance (left and right) at pantograph pan center when transfiniting, stagger sensor 1 will provide the stagger signal that transfinites, error＜0.5%.Vibration impact transducer 2 adopts magnetosensitive strain-type structures, and when hard spot impact acceleration during greater than limit value, vibration impact transducer 2 will provide and impact the signal that transfinites, and error is ± 3%.Stagger and vibration impact transducer are in light weight, and antijamming capability is strong, do not influence the operate as normal of pantograph.
