Based On The Fix, Grain Storage Automation And Control Systems Research And Applications

As a big agrtcultural country, the construction of grain depot in China is an important project. In recent years, China has increased its investment. In addition to building hundreds of reportorial grain and transfer depot of World bank successively, improving basic establishment and wiring were impoved, and stable material bases provided to their automatic control and integrate management. A grain depot is a system with a blend of network information technique, automatic control and integrate management based on the recent status of food supplies.This topic manufacture the transfer depot and PLC control system of Wushiji in Jiujiang. The head function of transfer depot is used to store and transfer food supplies, while the main task of its automatic system is used to attemper perfectly and offer original data information of food staff's in and out. The core craftwork flow is to store and transfer food supplies. According to the source and transporting destination the craftwork flow of transfer depot can be divided into four kinds, which are putting in depot, taking out from depot, turning the depot and transshipping.Design the operative monitoring control subsystem can offer logic control, catenation and inspectable to any subsystem,Exerting technology of information fasion can realize monitoring control to the conditions of electric machinery;using various information of sensors can get more credible measure results aviod confine of single sensor and reduce its influence of nondeterministic errors;planning harn humiture monitoring control subsystem can measure and note its temperature and humidity, Beesides, it can create alist automatically and put a seal on.And realize unwater, aeration and alarm control,utlizing FIX configuration procedure designs automatic constrol system of grain supply center,The proceduce is convenient in operation, simple in control.mireove, clear in interface and better worth in application...
