Embodiment Construction

[0010] The implementation process of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] like figure 1 The shown railway signal waveform display system based on the Android platform includes a UART data frame reorganization algorithm module, an original waveform display algorithm module, a waveform amplitude display algorithm module, and a waveform frequency display algorithm module.

[0012] When the railway signal detection device equipped with this system obtains the detection data, the UART data frame reorganization algorithm module reorganizes the received UART data with a specific algorithm to facilitate the processing and analysis of the subsequent algorithm module.

[0013] The original waveform display algorithm module processes the received recombined data frame with a specific algorithm, and then figure 1 The data is displayed as waveforms on the LCD display shown.

[0014] The waveform amplitude display ...

Abstract

The invention discloses a railway signal waveform recording / display system based on Android platform. The railway signal waveform recording / display system comprises a UART (Universal Asynchronous Receiver / Transmitter) data frame reorganization algorithm module, an original waveform display algorithm module, a waveform amplitude display algorithm module and a waveform frequency display algorithm module; due to the adoption of a portable detection device installed with the system, signals in a fault area ca be detected quickly, and looked up and diagnosed, and signal failure can be analyzed and processed conveniently and quickly.

Description

technical field [0001] The invention relates to a railway signal detection technology, in particular to a railway signal waveform recording and display system based on an Android intelligent platform. Background technique [0002] In recent years, with the implementation of the sixth phase of the railway speed-up project, especially the opening and operation of the Beijing-Tianjin intercity, Beijing-Shanghai high-speed railway, and Beijing-Guangzhou high-speed railway, a large number of signal equipment with high technical content such as microcomputer interlocking, ZPW-2000 and speed-up turnouts have been launched. For track use, due to the increase of train speed, unexplained failures such as instant loss of turnout indication, short-term red light band of track circuit or fluctuation of voltage curve often occur. Due to the short occurrence time of this kind of fault, the fault will recover naturally before the maintenance personnel arrive at the scene. It is very diffic...
