Method and system for wireless remote monitoring and control of a manufacturing execution system
First Claim
1. A method of remotely monitoring and controlling a manufacturing execution system comprising the steps of:
- providing a web server connected to the manufacturing execution system, the manufacturing execution system providing information to the web server and receiving control data from the web server;
providing a transcoding proxy connected to the web server;
receiving a request at the transcoding proxy from a wireless device, the request including wireless device data and request data, the wireless device data including information about the wireless device and the request data identifying information requested from the manufacturing execution system;
sending the request data from the transcoding proxy to the web server;
receiving a response from the web server at the transcoding proxy, the response including information responsive to the request data;
modifying the response at the transcoding proxy, based on the wireless device data, to a format compatible with the wireless device;
sending the modified response from the transcoding proxy to the wireless device;
sending a control command containing control data from the wireless device to the transcoding proxy;
relaying the control data from the transcoding proxy to the web server; and
forwarding the control data from the web server to the manufacturing execution system to control operation of the manufacturing execution system.

Abstract
A method of remotely monitoring and controlling a manufacturing facility through a manufacturing execution system (MES) uses wireless devices connected to a web server through a transcoding proxy. The wireless devices, such as portable digital assistants or cell phones, request information about the manufacturing process from the web server by requesting web pages containing the desired information. The web pages are modified by the transcoding proxy so that they may be correctly displayed on the screen of the wireless device. The MES can also be controlled by a wireless device. The wireless device passes control commands through the transcoding proxy to the web server, which sends them to the MES to control production in the manufacturing facility.
