【摘要】：本文从对制造完成后的预制梁需要养护的机理出发,提出了将传统的人工养护工作改成智能自动并具有远程监控的方法,研制了一套由PLC、3G网络和组态元件组成的梁场喷淋养护远程控制系统。减少了原有人工养护所带来的失误和不可监控现象得发生,通过现场触摸屏和PC监控中心的在线改变梁场运行参数,实现了实时监控梁场和事后记录查询的目的,对提高预制梁质量提供了新途径。该应用系统总体设计包括基于GSM网络的PC远程控制上位机监控平台软硬件设计、多个梁厂的数据融合,梁厂操作控制操作工业触摸屏控制系统、多路喷淋控制PLC、现场工业布线,无线数传模块DTU等系统硬件组网和软件设计。PC远程监测上位机是以力控Force/Control软件为开发平台,软件内容包括:用户操作权限设定,在线显示梁场的运行状态,设定参数监测;使用数据库SQL2000对梁场运行参数进行保存,在线对梁场进行实时监测的同时,对梁场的喷淋参数进行生成报表,细化到每具体个桥梁单元整个养护过程数据记录,为质量事故的分析提供重要依据。为了满足道路建设的移动特征,便于在工地变更时随时组网,中央控制计算机与预制梁厂的数据交换是通过DTU的3G网络。梁场控制操作选用工业触摸屏,通过RS232总线与PLC连接完成对梁场运行状态与参数进行改变,利用触摸屏控制操作方便,它有多个串行数据接口,它在完成本站数字图形化监控的同时与PLC控制器连接。根据梁场面积大的特点,从节约导线和提高可靠性方面进行了优化布线。PLC下位机主要是实现对现场数十个电磁阀的控制,它能在现场恶劣的环境下可靠工作,并能直接驱动电流冲击大且容易发生电路等故障的电磁水阀和水源大功率水泵的工作,通过其RS485串行接口与无线数传模块DTU通讯,用DTU接受远程上位机指令,完成回传数据的操作。系统优点还在于当上位机停止运行时,PLC自身的操作程序可以独立工作。论文对从现场控制柜到多路通水电磁阀的排布和现场合理线路连接方式等进行了设计,设计的系统已经在西咸北环线中铁24局的兴平标段中使用了一年半的时间,达到了客户的要求,为推广应用积累了成功经验。
[Abstract]:Based on the mechanism that prefabricated beams need maintenance after manufacture, this paper puts forward a method to change the traditional manual maintenance work to intelligent automatic and remote monitoring. A remote control system for spray maintenance of beam yard is developed, which is composed of PLCU 3G network and configuration elements. It reduces the errors and unmonitored phenomena brought by the original manual maintenance, changes the operation parameters of the beam yard on line through the touch screen and PC monitoring center, and realizes the purpose of real-time monitoring the beam yard and recording the query afterwards. It provides a new way to improve the quality of precast beam. The overall design of the application system includes the hardware and software design of PC remote control monitor platform based on GSM network, the data fusion of many beam factories, the operation control of beam factory, the industrial touch screen control system, the multi-channel spray control system, and the field industrial wiring. Wireless data transmission module DTU and other system hardware networking and software design. PC remote monitoring PC is based on the force control Force/Control software development platform, software content includes: user operation authority setting, online display beam field operation status, setting parameters monitoring; The operation parameters of beam yard are saved by database SQL2000, and the spraying parameters of beam yard are monitored in real time at the same time, and the data of the whole maintenance process of each concrete bridge unit are refined to the data record of the whole maintenance process of each concrete bridge unit. It provides an important basis for the analysis of quality accident. In order to meet the mobile characteristics of road construction and facilitate the construction of network at any time when the site changes, the data exchange between the central control computer and the pre-beam factory is through the 3G network of DTU. The industrial touch screen is used to control the beam field. The operation state and parameters of the beam field are changed by RS232 bus and PLC connection. The touch screen is used to control the operation conveniently, and it has several serial data interfaces. At the same time, it is connected with PLC controller. According to the characteristics of large area of beam yard, the optimized wiring. PLC lower position machine mainly realizes the control of dozens of solenoid valves in the field from the aspects of saving wire and improving reliability. It can work reliably in the harsh environment. It can directly drive the work of electromagnetic water valve and water source high power pump, which have large current impact and are prone to circuit faults. Through its RS485 serial interface, it communicates with wireless data transmission module (DTU) and receives the instruction of remote host computer with DTU. Complete the data return operation. The advantage of the system is that the PLC operating program can work independently when the upper computer stops running. In this paper, the layout of the field control cabinet to the multiway water solenoid valve and the reasonable connection mode of the field line are designed. The designed system has been used in the Xingping section of Railway 24 of the West and North Ring Line for one and a half years. Has met the customer's request, has accumulated the successful experience for popularizes the application.
