Technical field
The present invention relates to a kind of servicing unit of monitor of the railway signal, particularly a kind of portable track switch action current curve harvester.
Background technology
At present, the monitoring method of the track switch action current curve of railway signal centralized monitoring system is: the electric current of direct-current point machine is chosen action current loop line from noseplate or combination and obtained signal through DC current sensor punching sampling, the electric current exchanging goat samples from phase failure protector output terminal, thus isolation gathers track switch action current, the harvester of railway signal Centralizing inspection is by sampled signal operation amplifier, precision rectifying, operation amplifier again, signal condition, then the collection plate of track switch harvester is sent into, then deliver to CPU and carry out A/D conversion, collection plate again by the data temporary storage of Switch current curve after conversion in track switch harvester storer, then station machine is sent to store and display.Therefore, the monitoring technology of this track switch action current curve has the following disadvantages: current sensor is fixed on the rear of combined bay, when station machine is given an order and asked for data, a complete Switch current curve data is sent to station machine display, will check when railway electrical personnel overhaul that track switch action current curve can only be had access to by slave station machine, this is unfavorable for the outdoor upkeep operation of electric business personnel and improves the efficiency of fault handling.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of portable track switch action current curve harvester, so that the efficiency of the outdoor upkeep operation of electric business personnel and raising fault handling.
The technical scheme solved the problems of the technologies described above is: a kind of portable track switch action current curve harvester, comprises jaw type noncontact direct current and exchange acquisition module, Signal-regulated kinase, main control module, display module, power module; Described jaw type noncontact direct current with exchange acquisition module pincers in the action loop line of switch control circuit, this jaw type noncontact direct current is connected with the input end of Signal-regulated kinase with the interchange output terminal of acquisition module, the output terminal of Signal-regulated kinase is connected with the input end of main control module, the output terminal of main control module is connected with display module, and the output terminal of described power module is connected with the input end of main control module.
Further technical scheme of the present invention is: described jaw type noncontact direct current with exchange acquisition module and comprise direct current, AC current sensor.
Further technical scheme of the present invention is: described Signal-regulated kinase comprises the one-level operational amplifier, rectifier, the two-level operating amplifier that are connected successively.
Further technical scheme of the present invention is: described main control module comprises arm processor.
Further technical scheme more of the present invention is: described display module comprises the true color screen of TFT.
Due to adopt said structure, the present invention compared with portable track switch action current curve harvester prior art, there is following beneficial effect:
1. can be convenient to the outdoor upkeep operation of electric business personnel:
