The contact of pantograph and contact net, the data collected are turned by the amplification of data handling system progress signal, filtering, A/D
After the processing such as changing, form complete data report and send to designated terminal, be easy to follow-up work personnel carefully to be maked an inspection tour again
Investigation, improve the efficiency and precision of detection.
On the other hand, although in the past single acceleration detection can judge hard spot to provide foundation to a certain extent,
But it can not accurately judge and detect virtual value.The increased bow net contact tonometry of the present apparatus, phase when being run according to bow net
Mutual contact, the virtual value for judging that hard spot occurs is increasedd or decreased by contact moment, and two detection means coordinate
Using improving failure recall rate and accuracy of detection, and avoid using single parameter to be failed to judge when judging contact hard spot
Situation, reduce false drop rate.
And the present apparatus can be fit directly into operation rolling stock on, with operation locomotive operation, can whole day in real time detection connect
The contact situation touched net with pantograph, realize that operation is detectable on-line checking pattern, contact net hard spot can be found in time, had
Effect improves detection efficiency.
As preferred scheme of the present utility model, the pressure sensor is four.
As preferred scheme of the present utility model, the pressure is respectively installed in the bow both sides of the pantograph and passed
Sensor, it is favorably improved accuracy of detection.
As preferred scheme of the present utility model, the pressure sensor is arranged symmetrically relative to the bow midpoint, is had
Help improve accuracy of detection.
As preferred scheme of the present utility model, the data handling system is arranged on the locomotive on the left of the pantograph
On roof.
As preferred scheme of the present utility model, the data after the data handling system processing pass through optical fiber transmission mode
Send to designated terminal.By using optical fiber transmission mode, the network cable transmission signal mode generally used in the past is instead of, greatly
Improve transmission rate, ensure that the safety of roof high-pressure section.
As preferred scheme of the present utility model, the acceleration transducer is between operating temperature range is -20 ° -60 °
Wide temperature range type sensor.
As preferred scheme of the present utility model, the data handling system uses AT89C51 single-chip microcomputers.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
(1) in use, gathering the acceleration signal of pantograph by acceleration transducer, while adopted by pressure sensor
Collect the contact of pantograph and contact net, the data collected carry out signal amplification, filtering, A/D by data handling system
After the processing such as conversion, form complete data report and send to designated terminal, be easy to follow-up work personnel carefully to be patrolled again
Depending on investigation, the efficiency and precision of detection are improved.
(2) on the other hand, although in the past single acceleration detection to a certain extent hard spot can be judged to provide according to
According to, but can not accurately judge and detect virtual value.The increased bow net contact tonometry of the present apparatus, when being run according to bow net
Contacted with each other pressure, and the virtual value for judging that hard spot occurs is increasedd or decreased by contact moment, and two detection means are matched somebody with somebody
Close use and improve failure recall rate and accuracy of detection, and avoid using single parameter to be leaked when judging contact hard spot
Situation about sentencing, reduces false drop rate.
(3) and the present apparatus can be fit directly into operation locomotive on, with operation locomotive operation, can whole day in real time detection connect
The contact situation touched net with pantograph, realize that operation is detectable on-line checking pattern, contact net hard spot can be found in time, had
Effect improves detection efficiency.
(4) pressure sensor is arranged symmetrically relative to the bow midpoint, is favorably improved accuracy of detection；By adopting
With optical fiber transmission mode, the network cable transmission signal mode generally used in the past is instead of, greatly improves transmission rate, ensured
The safety of roof high-pressure section.
