A new bi-interlocking control device with plc 一种双闭锁控制装置的设计
Research of computer-interlocking control systematic fault diagnosis expert system based on neural network 基于神经网络联锁系统故障诊断专家系统的研究
Aimed at the needs of seamless rail production line, realized the interlocks control using plc, provided the plan of the system control and program design 摘要针对无缝钢轨生产线工艺流程的要求,利用plc实现了联锁控制,给出了系统控制方案及程序设计框图。
The interlock control of three-car coke oven is an essential component of the automatic control of the coke oven-transferring machine . it is also the major problem that coking enterprises should deal with in order to insure the security of production 焦炉三车的联锁控制是焦炉移动机车自动化控制的一个重要组成部分,是焦化企业生产安全保障的控制核心。
And then, we introduce the typical remote control software and its main functions . base on a detailed discussion of the designing requirements of remote control software and the effective ways to guarantee the system's reliability and security, we realize two remote control software on the c / s and b / s structure . in the last part, we develop an elementary remote diagnosis part of hj04a computer interlock control system on railway sianal combing with the computer-fault-diagnosing technology 本文首先介绍了远程控制的概念、原理和发展现状,以及常见的远程控制软件和所能实现的功能;然后在充分讨论通用远程控制软件的设计需求及如何保证远程控制可靠性、安全性的基础上,分别在cs、bs结构上实现了两种不同的远程控制软件;最后结合计算机故障诊断技术,初步实现了hj04a微机联锁控制系统中的远程诊断功能的开发。
As to the critical technological problems of the interlock control of three-car coke oven-oven number identification, accurate contraposition and data transmission, the author proposes solutions respectively-rfid, three-light positioning device, coke oven controller and radio transmission network . these solutions can ensure accurate identification of the oven number . for example, the deviation of the automatic parking position is within 10mm 针对三车联锁控制环节的关键技术:炉号识别、精确对正和数据通信,本系统采用了射频识别(rfid)装置、三灯位置检测装置、焦车控制器、无线通讯网络等解决方案,可实现无差错的炉号识别,自动停车定位误差在10mm以下,通信数据可靠等系统要求。
