The principle of action of the present invention is described below.
First, a signal generation process is described. Electric locomotives, motor cars, and urban rail vehicles all have various forms of power supplies that can provide electrical signals. In the invention, the electrical signal is converted into the optical signal, and the optical transmitter of the direct modulation method with direct current input is selected to directly control the semiconductor light source to emit light by the electrical modulation signal and couple the light into the optical fiber for transmission in consideration of only the on-off signal of the optical fiber to be transmitted.
Next, a signal transmission process is described. The pantograph 1 and the pantograph slide 110 serve as current-guiding members for obtaining electric energy from the power transmission network, the pantograph 1 is a high-voltage conductor as a whole in a working state, a high-frequency electromagnetic field exists between the pantograph 1 and the power transmission network, and the temperature of a contact part between the pantograph slide 110 and the power transmission network is rapidly raised locally. The optical fiber has the characteristics of high insulating property, electromagnetic interference resistance, high sensitivity, environmental corrosion resistance, long transmission distance, flexible structure and the like, the optical fiber is used for transmitting signals without being influenced by high voltage and high temperature rise of the pantograph 1 and the pantograph slide plate 110, the structure and the arrangement mode of the optical fiber are flexible, and the structural property and the electrifying property of the pantograph slide plate 110 cannot be influenced.
Since the plurality of optical fibers are pre-buried inside the pantograph pan 110, the pantograph pan 110 may be divided into a plurality of areas. Thus, when the pantograph pan 110 wears to a limit and has cracks or chipping, the optical fiber is damaged and broken to cause a change in light transmission performance. The fault region of the pantograph pan 110 can be determined by the change of the optical signal.
Next, the signal reception and processing procedure is described. The optical fiber transceiver 6 (photoelectric converter) is a device similar to a baseband MODEM (digital MODEM), and can convert an input optical signal into a fast ethernet data output, transmit the data to a micro-cabinet central processing unit through a wiring system, and the central processing unit outputs pantograph slider abrasion information in a graphic or text manner after programming on-off signals of each optical fiber.
The pantograph slide plate abrasion monitoring method and the pantograph have the following characteristics and advantages.
Strong anti-electromagnetic interference
Electromagnetic radiation of electric locomotives and motor cars during running is mainly caused by connection of a pantograph and a lead, contact resistance exists between the pantograph and the lead, and the pantograph and a power grid during running cannot be in tight contact. The equivalent circuit model of the contact surface cannot be a simple resistance model, but a model formed by a resistor, a capacitor and an inductor. Meanwhile, in the running process, the tightness degree of the contact surface of the pantograph and the conducting wire is changed continuously, and the equivalent circuit model parameters between the pantograph and the conducting wire are also changed continuously, so that the current flowing through the locomotive generates high-frequency harmonic current and high-frequency electromagnetic harmonic waves to the outside. The optical fiber transmission signal in the pantograph pan abrasion monitoring method is not influenced by an electromagnetic field, the signal attenuation speed is low, and the optical fiber transmission signal is stable and safe.
High sensitivity, real-time monitoring
The existing pantograph slide plate is limited by the strength and the arrangement position of an air pipe when the abrasion of a pantograph is limited to a limiting device (namely, a rapid pantograph lowering device), and the air pipe leaks air to enable a rapid pantograph lowering valve to act to lower the pantograph only when the abrasion of the pantograph is limited to the minimum limit. Limited by the action pressure range of the rapid pantograph-lowering valve, a small amount of air leakage caused by small cracks of the carbon strips of the sliding plate and the surface defects of the sliding plate cannot be detected, and the air leakage and the surface defects of the sliding plate can be possibly found only when workers visually inspect the pantograph. According to the pantograph slide plate abrasion monitoring method, the pantograph slide plate is divided into a plurality of areas in the height direction and the width direction by two optical fibers, when the slide plate is abraded to a limit and has cracks or blocks, the optical fibers are damaged, the light transmission performance is lost, the central processing unit processes signals and transmits the signals to the display terminal of the cab console, and operators of electric locomotives and motor cars can timely know the fault state of the pantograph slide plate.
Stable performance and strong weatherability
The optical fiber is preset in the pantograph carbon slide plate die before the pantograph carbon slide plate is formed, and the mechanical strength and the conductivity of the carbon slide plate are not influenced by the addition of the optical fiber; when the optical fiber is transmitted, the optical fiber is placed in the hose, a waterproof plug is adopted at the joint and protected by a heat-shrinkable sleeve, the direction and the fixing mode are the same as those of a pantograph gas circuit pipeline, the optical fiber passes through the plane of the top cover and enters a mechanical room, the optical fiber passes through the waterproof wire passing sealing piece, the optical fiber cannot be broken due to the action of the pantograph, and the ultraviolet resistance and the environmental corrosion resistance are strong; the pantograph-raising valve plate, the optical transmitter and the optical fiber transceiver are protected by a cold-proof temperature-self-control electric heating jacket, and can be heated to more than 0 ℃ within 5 minutes at the temperature of-30 ℃ so as to ensure that the pantograph-raising valve plate, the optical transmitter and the optical fiber transceiver can still normally work under the extremely cold condition.
Flexible structure and low cost
The optical transmitter, the optical fiber transceiver and the pantograph lifting valve plate are all arranged on the valve plate mounting seat, so that the structure is compact; the driving voltages of the optical transmitter and the optical fiber transceiver are DC 12-48V, the optical fiber transceiver converts the on-off signals of light into Ethernet signals and transmits the Ethernet signals to the central processing unit of the micro cabinet, and the system circuit is simple; the system output is Ethernet data, accords with the common Ethernet communication protocol, does not need to add other signal processing equipment, and the central processing of the micro cabinet can display the fault information of the pantograph slide plate on the display terminal of the cab console, so the cost is low, the structure is flexible, and the operation is easy.
