Abstract

The utility model relates to an on-line monitor of insulation resistance of electrified railway optical fiber against ground. At the part of the optical joint box, the insulation value of the armoredcable of the optical fiber against the ground is used according to ohm's law. The communication is performed through single optical fiber and solar energy is adopted for supplying power. The digital on-line monitor provided by the utility model can simply measure the insulation of the armored cable of the optical fiber against ground and can on-line return the measuring result to a machine room administrator. The digital on-line monitor is convenient and quick, and the manpower and material resource of filed monitoring are saved.

Description

The digitizing on-Line Monitor Device of electric railway optical cable insulation against ground along the line resistance
Technical field
The utility model relates to the on-Line Monitor Device of a kind of electric railway optical cable insulation against ground along the line resistance.
Technical background
In safeguarding the process of optical cable, regularly carry out the method that the insulation against ground of each section cable armor is measured with the maintainer usually, judge the situation of optical cable; Other has, the LMS optical cable detection system of Radiodetection Limited, and its measurement pattern is: power supply and signal all transmit by cable armor.The former has caused certain waste on manpower and materials; The latter, its drawback is---measurement point and host computer control end are far away more, and the cable armor of its perforation is just long more, and the longitudinal electromotive force that causes armouring to be responded under electric train voltage power transmission line is also just big more, has caused certain danger.
The utility model content
In order to overcome the drawback of traditional on-line monitoring technique, the purpose of this utility model is to provide a kind of on-Line Monitor Device easily and efficiently.
The utility model is achieved in that mainly to be made up of MCU, two photoelectric conversion modules, voltage modules, and MCU is connected with voltage module with photoelectric conversion module respectively.Two photoelectric conversion modules are sentenced the mode of relay and are carried out the transmission of information at cable splice closure; Adopt the voltage module of 0～5V control, 0～300V output, carry out stepless insulation values and measure; The power supply of employing sun-generated electric power.
The utility model adopts the optical cable information of carrying out to transmit, adopt sun power to power, its beneficial effect is, can be easily and efficiently with the insulation against ground value of each section cable armor in real time, online acquisition is to machine room server place, so that managerial personnel in time grasp the optical cable situation.
Description of drawings
Fig. 1 is the circuit structure schematic diagram of the utility model integral body.
Fig. 2 is the insulation values instrumentation plan.
Among the figure, 1 is MCU, 2 is solar electric power supply system, 3 is voltage module, 4,5 photoelectric conversion modules, and 6,7 is the single telecommunication optical fiber on light connector box both sides, 8,9 is the voltage module power output end, 10 is the output voltage source of voltage module, and 11 is the testing current module, and 12 is the insulation resistance between cable armor and the earth.
Specific implementation method
Below, for the utility model is described further, narrate an embodiment in conjunction with the accompanying drawings.
Fig. 1 shows whole circuit structure.Be made up of MCU (1), two photoelectric conversion modules, voltage modules (3), MCU (1) is connected with voltage module (3) with photoelectric conversion module respectively; Adopt solar powered.
Solar electric power supply system (2) places the on-site ground of light connector box, utilizes sun power to power for system.Remainder is installed in the instrument box for communication and measure portion, and communication adopts simple optical fiber to carry out; When host side sends to optical-electric module L (4) by optical cable (6) with order, MCU (1) obtains information by optical-electric module L (4), and analyze, judge that order is to need continuation transmission or oneself to carry out: if continue to transmit, MCU (1) will send signal on the optical cable (7) by optical-electric module (R); If order is to allow this device oneself carry out the measurement of insulation values, so, MCU (1) will trigger voltage module (3) measure institute's photometry cable armouring, MCU (1) is by the control voltage of control terminal output 0～5V, the voltage that voltage module (3) output 0～300V is increased progressively, MCU (1) measures the electric current in the power lead (9) simultaneously.
Fig. 2 shows the insulation values survey sheet.The voltage that voltage module output voltage source (10) output increases progressively is to armouring and on the ground big, and the insulation resistance between cable armor and the earth (12) formation loop, measures current in loop by testing current module (11).When electric current reaches 500 μ A or voltage and reaches maximum, carry out voltage stabilizing and measure, adopt Ohm law to calculate measurement result, MCU (1) with measurement result again by optical-electric module L (4)---optical cable (6) passes back to host side successively.The direction of the back information and the information of transmission is opposite, and logic is identical.

Claims (2)

1. the digitizing on-Line Monitor Device of electric railway optical cable insulation against ground along the line resistance, it is characterized in that: be made up of MCU (1), two photoelectric conversion modules, voltage modules (3), MCU (1) is connected with voltage module (3) with photoelectric conversion module respectively; Adopt solar powered.
2. according to the said on-Line Monitor Device of claim 1, it is characterized in that: said voltage module (3), with the output of 0～5V control, 0～300V voltage, stepless measurement cable armor insulation values.
