文档介绍:DISTRIBUTED TEMPERATURE CONTROL SYSTEM BASED ON MULTI-SENSOR DATA FUSION
Abstract:
Temperature control system has been widely used over the past decades. In this paper, a general architecture of distributed temperature control system is put forward based on multi-sensor data fusion and CAN bus. A new method of multi-sensor data fusion based on parameter estimation is proposed for the distributed temperature control system. The major feature of the system is its generality, which is suitable for many fields of large scale temperature control. Experiment shows that this system possesses higher accuracy, reliability, good real—time characteristic and wide application prospect
Keywords:
Distributed control system; CAN bus; intelligent CAN node; multi-sensor data fusion.
1. Introduction
Distributed temperature control system has been widely used in our daily life and production, including intelligent building, greenhouse, constant temperature workshop, large and medium granary, depot, and so on[1]. This kind of system should ensure that the environment temperature can be kept between two predefined limits. In the conventional temperature measurement systems we build work through RS-485 Bus using a single-chip metering system based on temperature sensors. With the aid of work, we can carry out centralized monitoring and controlling. However, when the monitoring area is much
