Remote Data Acquisition: Methods And Needs.Remote data acquisition system is used under many conditions. There are reasons why it should be employed. Similarly there are also ways for employing the Remote data acquisition system. It is very common to find that the information or data required flows from one end of the process plant to the other end of the process plant. There are also possibilities that the entire project of the process plant might spread over very large distances and areas. These two together necessitate the need to build a Remote data acquisition system to provide the information needed at the place where it is needed. What are the methods of Remote data acquisition? You can use any of the methods that are normally adopted by designers for such a data acquisition requirement. We can broadly look at the Remote data acquisition methods into two; one, the wired method and two, the wire less method. It is true both the methods are used extensively, but then the wire less is becoming more and more prominent because of the ease of usage and the comfort in operation and ease of maintenance. All these together move the hammer in favor of the wire less data acquisition methods. There are also advantages to the wired systems. They are more dependable and do not get disturbed by change in weather conditions. Similarly, they do not get hurt during standard and normal operations. There are possibilities that the data loss is noticeable in wire less operations. You may choose any of the methods that are used for Remote data acquisition depending upon your own specific choice and need. In the course of the normal working, it is quite common to find the need for Remote data acquisition to vary from the control room monitoring to some thing as important as management decisions. Today, with the wide spread of internet, the companies and their managements expect the need to monitor plants from their head quarters. There are companies that lay almost half way around the globe and the data is needed at the head quarters to take intelligent decisions. Remote data acquisition would refer to the large scale real time information capturing that collects the information and data and transfers it over wired networks for this purpose. There are also simpler and realistic reasons like monitoring in the control room. With a large reduction in man power in the offing in most of the companies, it is common to find the control room having data using Remote data acquisition all over the process plant. This information will help the company to find out whether everything is going through fine with the process. If there is any abnormality, then the control room can initiate action against to counter the cause. This would be another major reason for making use of the Remote data acquisition systems and modules in any of the process plants and their control systems. |
