Real Time Instrument communication and networking Design to support the replacement of legacy sensor with smart sensor.
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 4
Abstract
The need to acquire data real time is a priority in information technology system and process control industry. The acquisition of data via computer network, facilitate industrial process and enable easy measurement of industrial plant. However, it's important to have a data acquisition system that provides the flexibility to expand and change with the applications. The national instrument (NI) data acquisition systems are completely configured, so that we can choose the software, data acquisition (DAQ) devices, and signal conditioning that best fit the application needs. The priority of this paper is to replace the existing legacy sensors with a smart sensor and the integration of the smart sensor into industrial network architecture and implement a digital solution using any field bus standard protocol. The smart sensor is developed to address the problem of interfacing and communication protocol in our industries, such as; hardware interfacing wire and cable, Encoding and decoding of signal. But the foundation field bus is chosen as the industrial network solution that can provide transmission of additional device data alongside the measured value, such as status of the system and service information. More so, the foundation field bus is an industrial standard for distributed instrumentation and control (DICS) that enable digital communication within sensors and execute automatic control algorithms. The tree network topology is chosen for this design hence it can join multiple star topology into a bus that can connect Hub device to the network. The data or information obtained from the smart sensor is transmitted via the computer into a network where the information can be access by the manager or any authorise personnel. Indexterms: legacy sensors, smart sensor, network topology, foundation field bus, data acquisition, instrument communication
