Webprocessors for Measuring, Control and Synchronization

摘要

The Internet protocol (TCP/IP and HTTP) allows us to exploit new type of devices and algorithms that are suitable for building large and small sensor and knowledge networks. Even more importantly the ease of communication will allow us to build truly dialog based networks which we see as the next generation networks and artificial intelligence. Networks have many components. One of the basic components is what we call webprocessors. We describe a recently developed device that we named CTRLV4 and its smaller version that we call Miniserver. CTRLV4 is a server that can be controlled by parameters send to it via the GET method. CTRLV4 that evolved from previous versions interfacing ordinary small computers (window based pc's). Because this device is of a small size and understands HTTP protocol it is suitable for building large Internet protocol based networks. These networks can be built either as sensor networks or networks that can control other devices. In this paper we review some other devices, similar to CTRLV4, suitable for building cost conscious units and networks. The cost is one of the main factors because this type of networks should be ubiquitous. We present main features of the CTRLV4 PIC18F452 based micro-controller and typical network applications. These applications are suitable as an instruction tool, research tool and engineering tool. The applications we will discuss are temperature and motion monitoring and synchronization of non-linear oscillators
