Embodiment 1

[0019] Embodiment 1. Railway Signal Dynamic Board Detector

[0020] The concrete structure of the railway signal dynamic plate detector of this example is by figure 1 shown in figure 1 There are: DC power supply 1, socket 3 of railway signal dynamic board, conversion relay 4, current sensor 5, voltage sensor 6, integrated circuit module 7, display 8, sampling resistor 9, etc. This railway signal dynamic board tester is a testing instrument for the dynamic performance of railway signal boards. It has an instrument housing and a power supply. The power supply adopts a DC power supply, such as a DC 24V power supply. The railway signal dynamic board detector in this example needs to generate various pulse signals, analog quantity detection, display, conversion control, network interconnection and other functions. Siemens integrated circuit module S7212 integrates 6 inputs, 8 outputs, 2 analog quantities, A PPi interface is a better integrated circuit module to realize the above ...

Abstract

The invention discloses a railway signal dynamic board detector which belongs to the technical field of railway automatic control. The railway signal dynamic board detector comprises a detector casing, a power supply source, a mechanism which carries out simulation loading on a railway signal board and includes a signal source inputting simulation dynamic parameter to the railway signal board, a combination hub of the railway signal board, an input circuit of a simulation dynamic parameter signal of the railway signal board and a conversion and control circuit thereof and a detection and display mechanism of railway signal board dynamic parameter and performance which includes a dynamic parameter and performance sampling circuit, a detection circuit, a display circuit, etc. The detector is not reported both at home and abroad at present, and the detector fills the gap in the aspect. The detector tests the dynamic board by an analog signal, can be inter-communicated with a computer to analyze the detection result and discovers the inferior inclination of the railway signal dynamic board in advance, and the detector is an important tool for realizing condition-based maintenance and can ensure that the railway operation is safer. The railway signal dynamic board detector has strong practicability and is worthy of applying and popularizing.

Description

1. Technical field [0001] The railway signal dynamic board detector disclosed by the invention belongs to the technical field of railway automatic control, and specifically relates to a railway signal dynamic board detector. 2. Background technology [0002] The railway signal dynamic board is the main equipment in the execution layer of the railway signal microcomputer interlocking interface circuit to ensure the safety of fault guidance, and it is the key link to ensure that the relay will not operate incorrectly when the execution circuit is short-circuited. Since there are no special testing instruments at home and abroad, the maintenance of dynamic board failures is generally carried out in the way of failure repair, resulting in zero failure times, long failure downtime, and out-of-control equipment management; in severe cases, it leads to vehicle side frontal collision accidents. The invention takes the Siemens plc as the core, tests the dynamic board through the anal...
