摘 要 ：本文分析了地鐵車輛司機(jī)控制器的工作原理，指出了司機(jī)控制器性能檢測的必要性。根據(jù)司機(jī)控制器操作的邏輯關(guān)系，設(shè)計(jì)出檢測裝置硬件部分和測試軟件，并詳細(xì)地闡述了檢測方法，從而對司機(jī)控制器性能做出評價(jià)。司機(jī)控制器的測試臺就由此誕生了，該測試臺是測試司機(jī)控制器性能參數(shù)的工具。
測試臺的研制使用到了兩個(gè)主要的軟件是 STEP7 和 WinCC.
本文設(shè)計(jì)的是基于西門子 S7-300 系列 PLC 的司控器測試臺，本文詳細(xì)介紹了該測試臺的工作原理、系統(tǒng)構(gòu)成和測試結(jié)果。該系統(tǒng)設(shè)計(jì)了三種工作模式，包括手動測試和自動測試兩種選擇。本系統(tǒng)設(shè)計(jì)包括硬件設(shè)計(jì)和軟件設(shè)計(jì)兩部分，硬件設(shè)計(jì)部分包括硬件的選型和配置，軟件設(shè)計(jì)包括流程圖繪制和程序編寫。最后指出了系統(tǒng)設(shè)計(jì)過程中存在的問題，并給出相關(guān)解決的方法。
系統(tǒng)的仿真是通過WinCC完成的，通過該軟件我們可以對于測試臺進(jìn)行直觀的仿真控制。
該測試臺的性能良好，硬件模塊工作穩(wěn)定、可靠，能夠使用三種方式準(zhǔn)確的為我們提供該司機(jī)控制器的性能參數(shù)。并且在測試完成后可以將測試結(jié)果測試日期記錄到excel表格中，供以后查找。

The Test Board of Master Controller Based
on PLC
Abstract:This paper analyzes the working principle of the master controller of subway vehicle and points out the necessity of performance testing of the master controller. According to the logical relationship of the master controller operation, testing device of hardware and testing software are designed and testing methods are reviewed in detail, thus ,the eva luation on the performance of the master controller is made. The test board of master controller is thus born and it is the tool for testing the performance and parameters of master controller.
In the process of developing test board, two software, STEP7 and WinCC are mainly used.
Based on Siemens S7-300 series PLC, this paper designs the test board for master controller. In this paper, the working principle, system constitution and the testing results of the test board are introduced in detail. In this system three working modes are designed and two choices, manual testing and automatic testing are included.The design of the system includes two parts: hardware design and software design. Hardware design includes hardware selection and configuration while software design includes flowcharts drawn and programs written. Finally the problems in the process of the system design are pointed out and the relevant methods of resolving the problems are provided.
System monitoring is done through the WinCC and through the software we can intuitively control the test board.
The performance of the test board is good and its hardware module works stably and reliably. It can accurately provide us the performance and parameters of the master controller using three kinds of test methods. Test date and test results can be recorded after the test to excel table for future lookups.
