【摘要】：煤矿矿井生产的机械化、自动化水准在不断提高,工作面规模也在不断扩大,这样就对井下供电安全提出了更高的要求。此外,在煤炭价格大幅下降的新形势下,如何以最低的造价,充分利用现有高(低)爆开关内置的各种品牌的综合保护器和通讯线路构建响应快速、安全可靠、可覆盖所有通讯协议的煤矿供电监控系统,既能减员增效,又可确保供电安全,现实和经济意义重大。为了进一步提升煤矿的自动化程度,达到安全生产、减员增效的目标,本文以安徽省科技项目“高速智能可编程串口交换机(控制器)技术研究”为背景,依托于淮北矿业集团公司祁南煤矿供电监控系统的设计项目为试验平台,搭建了一套基于PSC (Programmable Serial Controller,可编程串口控制器)技术的煤矿井下供电监控系统,可以覆盖现场种类和通讯协议繁多的综合保护器,实时读取开关运行状态和运行参数,控制开关分合,调整开关整定值,从而实现了对供电系统的遥测、遥信、遥控、遥调、遥视的“五遥”功能,并通过井下环网无缝接入矿井自动化平台。本系统在硬件配置方面,下位机采用广东罗尔科技有限公司研究开发的可编程串口控制器(PSC),通过配套的Rstep编程软件实现现场数据的采集、转换及现场综合保护设备的控制等功能。上位机选用组态王监控组态软件,开发组态画面,实现供电系统的远程实时监控、参数调取、参数修改、报警指示及历史数据的存储和打印等功能。完成整个系统的硬件配置,软件组态,上、下位机之间及下位机、现场设备之间的通讯和程序开发。经过多次现场试验和井下试验,系统运行稳定,实现了控制要求,解决了现场串口总线通讯在中、大规模应用中速率低、延迟时间长的问题,同时还能够兼容现场具有不同种类通讯协议的智能设备,减少了软硬件成本的投入。
[Abstract]:The mechanization of coal mine production, the level of automation and the scale of the working face are constantly improving, which puts forward higher requirements for underground power supply safety. In addition, under the new situation of coal price falling sharply, How to make full use of all kinds of integrated protectors and communication lines built in by the existing high (low) exploding switches at the lowest cost to build a coal mine power supply monitoring system that can respond quickly, safely and reliably, and can cover all communication protocols. In order to further enhance the automation of coal mines and achieve the goal of safe production and efficiency reduction, it is of great practical and economic significance to reduce staff and increase efficiency. Based on the technology research of high speed intelligent programmable serial port switch (controller) of Anhui province science and technology project, this paper bases on the design project of Qinan Coal Mine Power supply Monitoring system of Huaibei Mining Group Company as the experimental platform. A coal mine underground power supply monitoring system based on PSC programmable Serial controller (programmable serial port controller) technology is set up. It can cover the comprehensive protector of various kinds of field and communication protocol, and read the operation state and parameters of switch in real time. Controlling the switch splicing, adjusting the switch setting value, thus realizing the "five remote" functions of the power supply system, such as telemetry, remote communication, remote control, remote adjustment and remote viewing. And through the underground ring network seamless access to the mine automation platform. This system in the hardware configuration, The lower computer adopts the programmable serial port controller developed by Guangdong Luo er Science and Technology Co., Ltd., and realizes the collection of field data through the matching Rstep programming software. The upper computer selects configuration software to develop configuration picture, realizes remote real-time monitoring of power supply system, parameter adjustment, parameter modification, and so on. Alarm indication and historical data storage and printing functions. Complete the hardware configuration of the whole system, software configuration, communication and program development between upper, lower and lower computers, and field equipment. After many field tests and underground tests, The system runs stably, realizes the control requirement, solves the problem of low speed and long delay time in the field serial bus communication, and can also be compatible with the intelligent equipment with different communication protocols in the field. The cost of hardware and software is reduced.
