焦炭塔操作仿真培训系统设计

Design of simulation training system for coke drum operation

为了避免焦化生产过程中人为原因造成的安全事故,设计了一套焦炭塔操作仿真培训系统.首先采用模块化的设计方法,每个装置都是一个单片机构成的仿真.在每个阀门模块上设置有三个按键用以模拟实际阀门的三个操作按钮,阀门模块上还设有一排发光二极管(LED)灯,在仿真过程中模拟阀门的开度,焦炭塔模块上也设有LED灯,用以模拟塔顶底盖的开度和塔内物料的百分比.各模块之间使用标准MODBUSRTU协议进行连接,共同组成焦化生产工艺流程.最后该装置与内操组态系统连接,完全模拟焦炭塔生产过程中的行为属性.因此操作员工可以在仿真系统上模拟延迟焦化的工艺流程,熟悉实际生产过程中的每一个步骤.通过实际使用,该系统能正确模拟焦炭塔的生产过程流程,方便操作工的培训.通过更改软件还可以让系统适应不同炼厂焦化操作工艺的需求.

To avoid the safety accidents caused by improper operations from the workers in coking process,a set of coke drum operation simulation training system was introduced.Firstly,the blockedbased design was adopted and every device was a kind of simulation made by a control ship for simulating the performance of the device.Three keys were set in each valve module to simulate the performance of three operation buttons of the real valve and there were a row of light emitting diode（LED）lights on the valve module to simulate the opening in simulation process.Some LED lights were also located in coke tower module to simulate the opening of the bottom cover at the tower top and the ratio of the tower materials.Further more,each control ship was connected by the MODBUS-RTU protocol to construct the coking process.Finally,the device was put in inner formation connection of the system and fully imitated the behaviors of the coke drum in process.Thus,manipulators can simulate the delayed coking process and control every step of the actual production process by the simulation system.Experiment results show that the process of coke drum is simulated correctly and the manipulations can be conducted by workers perfectly in practical use.Different coking process demands can be satisfied by the system with altering the software.
