在传统的光纤分配网(ODN)中,施工人员采用纸质工单进行施工,施工效率和正确率低,光纤设备资源浪费严重。为了解决此类问题,设计并实现了一种ODN远程施工系统。论文首先介绍了该系统的设计方案以及工作原理,然后介绍了系统的硬件设计与软件开发实现。论文重点阐述了系统硬件中蓝牙通信模块和单片机控制器的设计与开发,以及系统软件中服务器工单子系统和移动施工客户端程序的设计与实现。使用该系统时,施工人员利用移动施工客户端通过网络以Web Service方式从工单子系统获得施工命令,然后通过蓝牙通信模块将施工命令转发给施工设备上单片机控制器,从而实现对光缆交接箱的施工控制。实际测试结果表明,使用该系统得到的电子施工结果正确,可以有效提升运营商对于ODN资源的管理效率。 相似文献

This study tried to control and monitor computerized numerical controller (CNC) machines anywhere and anytime for machine
(mobile) to machine (M2M) application in wired and wireless environment of upcoming ubiquitous manufacturing systems (u-Manufacturing).
With a personal digital assistant (PDA) phone, the machine status and machining data of CNC machines can be monitored in wired
and wireless environments, including the environments of IMT2000 and Wireless LAN. Moreover, CNC machines can be controlled
anywhere and anytime.
The concept of the anywhere-anytime controlling and monitoring of a manufacturing system was implemented for u-Manufacturing
in this study. In this concept, the communication between the CNC controller and the PDA phone was successfully performed
anywhere and anytime for the real-time monitoring and control of CNC machines. In addition, the interface between the CNC
controller and the developed application module was implemented by object linking and embedding for process control (OPC)
and shared CNC memory.
For communication, the design of a server content module within the target CNC was based on a TCP/IP. Furthermore, the client
content module within the PDA phone was designed with the aid of embedded c++ programming for mobile communication. For the
interface, the monitoring data, such as the machine status, the machine running state, the name of the numerical control (NC)
program, the alarm and the position of the stage axes, were acquired in real time from real machines with the aid of the OPC
method and by sharing the CNC memory. The control data, such as the start, hold, emergency stop, reserved start and reserved
stop, were also applied to the CNC domain of the real machine.
CNC machines can therefore be controlled and monitored in real time, anywhere and anytime. Moreover, prompt notification from
CNC machines to mobile phones, including cellular phones and PDA phones, can be automatically realized in emergencies. 相似文献
