Abstract
A new design of hardware and software required for networking a computer controlled radiation monitoring system is presented. This radiation monitoring system comprises a network of area radiation monitors connected to a central computer via an interface module. The monitors are employed for area dose-rate measurement and controlled via the network. For increasing the distance between monitors and central control and reducing the transmission error, a kind of bus networking which is controlled by the interface module is used. The interface module is specially designed for network control and acts as an bus master. With this interface, there is no need to Ethernet cards in each dose monitor. Communication between the monitors and bus master is carried out by two transmission lines to send and receive, using RS485 standard to benefit by a low cost and simple hardware. In this communication platform, a special protocol is used to reduce the transmission error. This kind of networking is an optimum solution for distributed monitoring systems.
