Description
Technical field
The present utility model relates to railway monitoring equipment technical field, particularly a kind of for interval orbit circuit synthesis monitoring system off-premises station acquisition terminal.
Background technology
Frequency shift modulated track circuit is the important component part of railway signals equipment, is also one of key equipment affecting safety of railway traffic.Frequency shift modulated track circuit outdoor equipment because quantity is many, have a very wide distribution, and away from signal work area, it is patrolled and examined to tour and will spend the plenty of time and be used on road, once generation equipment failure, often the processing time long, cause fault time delay longer, very large on conevying efficiency impact.
The centralized signal supervision system that upper track has been used is at present less to the Contents for Monitoring of interval frequency shift modulated track circuit, and be all to test indoor, lack the monitoring to outdoor trackside equipment electrical characteristics, be difficult to comprehensively the fully true utilization state of reflection Block signaling equipment.While breaking down, signal personnel just can find out device type or the position of breaking down after often only having the interval scene of arrival, if do not carry enough instrument and meters, instrument and standby redundancy in advance, be often difficult to timely prosthetic appliance, to fault handling, bring difficulty.Special on the high iron wire and Line for Passenger Transportation of China, problem is particularly outstanding, because the Block signaling equipment quantity of administering is many, maintenance personal is few, skylight point is nervous, faces larger pressure in physical device maintenance work.
Utility model content
Technical problem to be solved in the utility model is, overcome problems of the prior art, a kind of railway section track circuit comprehensive monitor system off-premises station acquisition terminal is provided, utilization state that can Real-Time Monitoring frequency shift modulated track circuit, it can repair for frequency shift modulated track circuit equipment enforcement state and provide in detail, necessary and device status data accurately, for realizing the state of frequency shift modulated track circuit outdoor equipment, repair and provide strong support, the effectively generation of prevention apparatus fault.Once generation equipment failure, also can realize trouble spot location, on-call maintenance, the time delay of shortening fault fast, and can effectively reduce signalman's labour intensity, improves its work efficiency.
In order to address the above problem the technical solution of the utility model, be such:
A railway section track circuit comprehensive monitor system off-premises station acquisition terminal, comprises the isolation voltage sensor of some voltage samples and the isolation current sensor of some current samples; Isolation voltage sensor connects the CPU module that can carry out A/D sample conversion by shaping amplifier; Isolation current sensor connects described CPU module by voltage transformation module.
Described CPU module connects a sense terminals by 485 buses.
Beneficial effect, this terminal is carried out Real-time Collection to the electric current of tuning matching unit ladle copper cash by root, and object is the reliability of installing in order to detect ladle copper cash.System can be found the ladle copper cash loose contact fault such as even break in time.To rail level magnitude of voltage, cable side voltage carries out Real-time Collection, can provide data supporting to the variation of equipment rail surface voltage in service and cable side voltage.The utmost point impedance of tuning matching unit, zero impedance have been carried out to vector calculating.The operating mode that can fully show resonance matching unit.Carry out seamless link with microcomputer monitoring, thereby the network channel of shared microcomputer monitoring has reached the object economizing on resources.Early warning information and warning message are accurately provided.Combine with microcomputer monitoring, the closed loop that has realized track circuit equipment detects, and for state, repaiies reliable data supporting is provided, and to trouble spot, can locate comparatively accurately.
