Design and Application of Double Redundancy System for Public Tide Discharging from Tobacco Leaf Silk
In order to reduce the problem of equipment shutdown caused by total drainage of tide in tobacco leaf silk making process,the reason of communication signal loss is analyzed from the communication between the main drain tide and the drying machine,The first is to alarm the tide discharge communication failure,The second is to design the redundant control function of electrical signal and network signal to start the total tide discharge,Thirdly,the redundant function of feedback signal and network signal in tide drainage operation is designed to avoid the shutdown of the drying machine due to the instantaneous loss of network signal,The double system redundancy control of program communication control and hard-connected signal line control is proposed and realized for the first time to achieve the purpose that the drying equipment can accurately and accurately control the tide removal equipment.The results show that:1)The normal operation rate of total tide discharge is 100％;2)The machine stop caused by the instantaneous loss of the feedback network signal of the general tide discharge operation is avoided;3)The equipment runs stably and solves the wrong shutdown caused by unqualified process index.
