Application of Inter Control controller in electrical control system of roadheader

Requirements about controller of electrical control system were analyzed according to condition of roadheader working field. For low protection hierarchy and poor environment adaptability of traditional electrical control system of roadheader which took PLC as a core, an appropriative controller named Inter Control was taken as a core of electrical control system of roadheader on the basis of performance comparisons of existing appropriative controllers. Hardware composition of the electrical control was introduced in detail as well as design scheme of controller program. Inter Control controller has been successfully applied to an electrical control system of all-rock roadheader. The industrial test underground shows the electrical control system overcomes disadvantages of traditional ones based on PLC, and runs stably and reliably without any communication faults.
