Development of gateway for industrial controllers

摘要

Internet of Things(IoT) finds a wide application in the field of industry. Nowadays, the controllers and devices in the industrial fields are controlled by application installed in the Operating Systems(OS). The limitation of the existing system is that, the application used to monitor and control the systems cannot be used if the current OS is upgraded. Hence software maintenance is quite difficult. In this scenario, introduction of IoT will be a better solution. The development of gateway is a web server based module for remote monitoring of industrial controllers through a standard web browser in any computer connected to the network. The gateway is built around LPC1857 which is an ARM Cortex M3 based microcontroller. The system has multiple communication interfaces like RS485, CAN and Ethernet. It acquires data from the field and serve as a web page to any computer in the network.
