毕业设计（论文）-化工设备手持式巡检器的设计.doc

摘要
在化工生产中,对于重要生产过程的大型关键设备的巡检,往往采用在线监测仪器仪表系统,其体积庞大不便携带,手持式化工设备巡检器就应运而生。手持式巡检器能够解决巡检人员的巡检不到位、伪造记录、不按制度落实巡检计划等问题,加强对巡检人员的巡检工作的有效管理。
本设计给出了化工设备手持式巡检器的设计方案。以单片机应用系统为控制核心,应用单片机技术、电子电路技术和EDA技术,设计了手持式巡检器,实现对化工设备的定人、定时、定点、定量巡检。通过系统的预先设置巡检计划来限定特定特定人员、特定时间、特定地点及设备参数的巡检范围,可满足各种场合的设备巡检,方便记录人员到达巡检地点的时间及状态信息。该巡检器主要由STC89C52单片机及外围电路、非接触式IC卡读卡模块、液晶显示模块、时钟及键盘模块组成。能够方便的实现对生产设备的数据采集和数据上传的功能。
本文设计的手持式化工设备巡检器体积小,携带方便,操作简单,可存储多条巡检记录,并且可以通过串行接口与计算机系统实现数据交换,可广泛应用于其他重要生产设备的巡检。

Abstract
In the chemical production, on-line monitoring instrumentation systems are often used to inspect the important large key equipments, but thess are inconvenient to carry the sheer volume, hand-held chemical inspecting devices emerge as the times require. A hand-held inspecting device can solve the problem of strengthening the inspection personnel and effective patrol inspection; falsify records, inspection not in place, not by the implementation of the system.
This design gives a solution of hand-held inspecting device of chemical equipment. The system adopts the single puter application system as the control core, the single-chip technology, electronic circuit technology and EDA technology are used to design a scanning device to realize the inspection of chemical equipment. The special equipment, special time, special place, and special personnel of the inspection system through the predetermined range, can meet a variety of occasions special inspection, convenient recording personnel arrived at the polling place on time and state information. The inspection device is posed of STC89C52 MCU and its peripheral circuit, non-contact IC card reader module, LCD display module, the clock and the keyboard blocks, to facilitate the realization of the production equipment for data collection and data uploading function.
The inspecting device has the advantages of small size and easy to carry, simple to operation, it can exchange data with puter system through the serial interface, and ca
