Abstract: The Access control systems are specialized process control systems used in industries, big corporate offices for applications like controlling the access of individuals to a building, elevator control, fire control, and intrusion detection among others [1]. The access control system consists of a centrally located host and a network of micro-controllers distributed over the area under control. The host has database for the complete system and monitors the alarms and status information of all the micro-controllers [2]. The micro-controller is a microprocessor based controller, having the firmware and configuration data to operate the devices like alarm, sensors and relay panels, readers for magnetic, bar-code, and proximity type badges. This dissertation is concerned with the protocol used for host to micro-controller and inter micro-controller communication. The dissertation work involved understanding of the existing protocol used in older version of the micro-controller called Micro/5, for the purpose of designing, implementing and testing of the protocol for a new micro-controller, Micro/6. As a result of this project work, a communication protocol has been designed, implemented and tested for inter-Micro/6 and Micro/6 - host communication. The protocol is used for asynchronous transfer of variable size packets. It facilitates reliable transport of messages. It supports three different media channels - serial line (based on RS-232), dial-up line(modern connection) and network (based on LAN/WAN). The protocol handles the media channel failures and switches to back-up media channel in event of failure in the working channel. The coulmunication protocol also provides for diagnostic information for system debugging and fault diagnosis [3]. The major challenge in this project has been in reverse engineering of the existing protocol, which does not have sufficient documentation for Micro/5 and in designing it for a completely new system (Micro/6) with a different hardware architecture and a new operating system, embedded Linux. The complete design, coding and testing of the protocol was carried out at GE- India Business Center at Hyderabad. Six Sigma standards were used throughout the development phases to track and meet the performance specifications [4].
