A new distributed control system for conservation and maturation of bananas based on CAN and Internet networks

In the conservation and maturation systems of fruits it is very important to have faithful information about certain parameters that indicate the fruit state, and that allow to take the appropriate proofreaders actions in order to achieve an optimum controlled fruit maturation. In front of the rudimentary control systems that are being used at the present time, the Fault Tolerant Systems Group of the Polytechnic University of Valencia together with POLARIS TECHNOLOGY S.L company, have developed a new distributed control system based on CAN and Internet networks that allows a remote pursuit and control in real time of these processes. In each cold store, there are a strategically distributed set of sensors and actuators that are interconnected by means of a CAN network. One node centralizes the information, so that after its filtrate and storage is overturned on a backbone CAN network that interconnects all cold stores with a PC in charge of carrying out a second treatment and storage of the information and its diffusion to Internet. This system is completely operative and it has been already installed in different companies of several countries, obtaining very interesting results.
