Signal monitoring lightning protection distribution cabinet and its signal acquisition system

Abstract

The invention discloses a collection module used for signal monitoring anti-thunder distribution cabinet. The collection module comprises a circuit board; one side of the circuit board is provided with an interface unit which is used for connecting to a collection leading terminal of a corresponding distribution seat; the circuit board is provided with a voltage signal distribution terminal comprising a wire inlet terminal and a wire outlet terminal, a voltage signal processing circuit, a current signal processing circuit, and a data processing unit, wherein the wire inlet terminal is correspondingly connected to the terminal introducing voltage signals on an interface unit, and the wire outlet terminal can be arranged; the voltage signal processing circuit performs collection processing on introduced voltage signals and outputs the voltage signals, the current signal processing circuit performs filtering on introduced current signals and outputs the current signals after amplification processing, the data processing unit is used for receiving and processing current signals and voltage signals to obtain practical voltage and current data of a device to be detected, and the data processing unit transmits the practical current and voltage to the outside. The invention also relates to signal monitoring anti-thunder distribution cabinet plugging the collection module.

Description

technical field [0001] The invention relates to the field of railway signal monitoring and processing, in particular to a signal monitoring lightning protection distribution cabinet and a signal acquisition system thereof. Background technique [0002] At present, the branching, protection and monitoring collection of railway signals and their equipment are scattered in different places, without centralized monitoring and collection, the location of the collection sensors is scattered, the collection of analog information is single, the wiring construction is complicated and chaotic, and the signal lines may be indoors. Mutual interference occurs, resulting in inaccurate monitoring fault information, which is not conducive to timely and accurate fault handling by on-site maintenance personnel. Since the existing railway signal equipment mainly includes three categories: switch machine, signal machine, and track circuit, plus other scattered equipment for a pair of lines, the...

[0002] At present, the branching, protection and monitoring collection of railway signals and their equipment are scattered in different places, without centralized monitoring and collection, the location of the collection sensors is scattered, the collection of analog information is single, the wiring construction is complicated and chaotic, and the signal lines may be indoors. Mutual interference occurs, resulting in inaccurate monitoring fault information, which is not conducive to timely and accurate fault handling by on-site maintenance personnel

Since the existing railway signal equipment mainly includes three categories of switch machines, signal machines, and track circuits, plus other scattered equipment for a pair of lines, the parameters that need to be collected by different types of signal equipment, the range and accuracy range are not completely consistent.
