Section insulator is a kind of insulator arrangement that contact net adopts when carrying out electric segmentation.The annual event that the timely repairing of a lot of section insulators damages all can occur and affect the normal operation of railway on electrification railway contact net.Fault can take a large amount of manpower and materials and go to rush to repair after occuring, and has a strong impact on the transportation safety of electric railway.Based on this problem, native system provides a kind of device of on-line monitoring of contact net section insulator.To the section insulator Real-Time Monitoring, have the functions such as life-span early warning, fault alarm when this system has realized that train is passing, improved greatly the section insulator Operation safety.
The present domestic monitoring equipment of studying section insulator, up to the present all that the monitoring of section insulator is thoroughly imperfect, substantially all be that artificial scene is gone to overhaul, yet this maintenance often can not solve the loss that the sudden damage of section insulator causes, and this maintenance waste of manpower is larger, and some potential safety hazards may appear, the person is threatened, the words that break down at complete rear equipment of time between overhauls(TBO) simultaneously are difficult to again maintenance, have caused massive losses on this railway.
Both at home and abroad also proposed the methods such as sonar detection and infrared acquisition in the research to the section insulator monitoring, sonar requires higher to surrounding environment, produces vibrating noise etc. around train and can have influence on its effect; Infrared also higher to environmental requirement, the variation of temperature than very fast, makes Infrared survey be very restricted throughout the year, and the performance of infrared monitoring section insulator is not widely used yet for this reason.
Based on above problem, the on-line monitoring of contact net section insulator has been carried out large quantity research, and be eager to change into contact net section insulator on-line monitoring system product.
Summary of the invention
For solving above technical matters, the purpose of this invention is to provide a kind of contact net section insulator on-line monitoring system, this system is conducive to the passing number of times situation of train Real Time Monitoring record and higher limit can be set, and will send warning when exceeding specified number of times when train is passing from the section insulator; Equipment set carries out Real-Time Monitoring with the video software analysis to section insulator, and it is multiple abnormal on-the-spot that video can analyze fracture of occurring on the arcing phenomenon of equipment and section insulator etc.
for realizing goal of the invention, the technical solution used in the present invention is to provide contact net section insulator on-line monitoring system, and wherein: this system includes video camera, solar electric power supply system, 3G video server, control box casing, accumulator, lightning protection device, solar panel, erecting frame, terminal device, NodeB, railway internal router, supply line, 3G WLAN (wireless local area network), communication data line, described control box casing, solar panel is located in described solar electric power supply system, be provided with interconnective photovoltaic controller in the control box casing, the 3G video server, accumulator, lightning protection device, solar panel is connected with accumulator by cable, accumulator is connected by cable with video camera by supply line, for camera power supply is provided, video camera is connected with the 3G video server by cable, video camera through the communication data line with video data transmitting to the 3G video server, the 3G video server is transferred to NodeB with vision signal by the 3G WLAN (wireless local area network), the railway internal router is by 3G WLAN (wireless local area network) acknowledge(ment) signal, and transfer to control terminal, terminal device carries out on-line analysis to the fact of case of video segmentation insulator.
Effect of the present invention be this application of installation in the contact net section insulator, electric locomotive by the time, the video in the time of can effectively contacting with section insulator according to the train pantograph judges whether section insulator has obvious arcing phenomenon.
Can also count the number of times that train crosses from the section insulator granting, the number of times that can bear the train process as section insulator generally is 5000 times, and the passing number of times of train will be reported to the police greater than 5000 times so.Thereby reach the purpose of defence maintenance in advance, effectively solved the accident problem that breaks down and produce because of section insulator.Use sun power to power and to continue to use 15 days under rainy weather.This system is the 24V direct current, wherein solar storage battery depth of discharge coefficient is 0.7, and inversion efficiency is 85%, and the total load of equipment is the 12W(3G video server), 36W(video camera peak power) worked every day 24 hours, according to 10 days calculated capacities of continuous rainy weather:
（12W+36W）×10×24/24V×0.7×0.85=11520/14.28≈807Ah
Consider the decay of follow-up life of storage battery capacity, select three, the accumulator of 600Ah/12V.Wherein the capacity of solar panel calculated according to average peak in 6 hours on duty for the day, and system's absorptivity gets 90%, and the power of required solar components is:
48W×6×90％=1152/5.4≈259W
Consider the cloudy weather that wait to disturb, solar panels are selected, four of 95W.
So just can normally move by assurance equipment, the fact of case that detects section insulator that integral body can be contactless if any extremely just sending alerting signal, is guaranteed the operation that contact net is safe and reliable.This device can analyze occur under the section insulator fact of case abnormal and exceeds the phenomenon such as setting value as fracture, arcing, the passing number of times of train and send alerting signal.
This system can embody following advantage in the primacy on technical pattern and the economy on price:
1, can carry out non-contacting monitoring to section insulator;
2, product 3G wireless technology is carried out data transmission, remote monitoring;
3, can the number of times of passing train be added up, can analyze the size of train arcing degree when passing, can analyze section insulator and fracture whether occurs and report to the police.
