Research Of Alarm And Alarm In Advance System Based On Industrial Data

The process of industry production which utilizes a great number of equipments is very complex. How to keep watch on the state of the working and the trouble of the equipments so as to ensure the production regularly goes on becomes the first thing that the production unit concerns about. At the same time, the alarm system which uses single way of giving an alarm may easily make the operators neglect the existence of the alarm system. Therefore, researching of the fieldbus and related internet technology which can be used for the ensurance of security has large significance. This paper is focused on the design and implement of the alarm linkage system and study of the PROFIBUS, OPC, and TCP technology on the base of the situation of the transformer substation, heating, cooling, natural gas and air-conditioning systems of the power energy department of a cigarette factory. The alarm linkage system, which constructs the field control network via the fieldbus PROFIBUS-DP, gathers the alarm signals based on OPC, integrates the Broadcasting Public-Address Systems, Video Surveillance Systems and SMS Gateway System by TCP/IP, provides effective safety protection of industrial process through various ways of alarm such as audio and video.Because the alarm system may only reflect the device failure, it can't avoid the device accident. If we can descript and forecast the device development trend, then it can provide us scientific guide for equipment repairing. Therefore, the paper wants to do some research on the forecasting of the status of refrigeration unit by time series analysis. Firstly, it gives some concepts of the series models. Secondly, the industrial data are applied to the models .Finally, the result demonstrates that time series model which can be applied to the forecast of the status of the equipments can be a reference to the judgment of the status of the equipments.
