摘要
设计了一种基于MPI的电加热强对流罩式光亮退火炉控制系统。针对传统的继电器控制系统的控制线路复杂、调试维修成本高等问题,提出了在监控上位机和SIEMENS S7-300的从站、智能温控仪表之间采用9.6K的MPI通讯网络连接,实现了自动控制设备间信息高速稳定的传递。该控制系统在现场的实际应用表明,它对保证产品质量具有积极的意义,能取得较好的结果。
A control system of bell-type luminous annealing furnace based on MPI （ MultiPoint Interface ）is designed. The furnace is heated by electricity,and the convection is strong in the furnace. Aim at traditional electric relay＇s disadvantages such as complex circuits,high costs of maintenance and so on,a method is presented. Namely,MPI network with the rate of 9.6K is used among the HMI（Human Machine Interface ）,secondary stations of SIEMENS S7-300 and intelligent temperature-controlled instruments,and the information between automatic control devices can be transmitted with high rate stably. By the application of the control system in the worksite,it is turned out that the system can guarantee the quality of products ,and the result is satisfactory.
