Development System Based on a Programmable Logic Controller PLC-OMRON to Safety Doors State Control of the Shaft-Sinking Process

This paper analyses the real-time software structure of a development system based on OMRON Programmable Logic Controller PLC designed to control the safety doors of the dynamic shaft-sinking process. The rock excavation and loading process into the front, directly depends on the good functionality of the shaft platform safety doors. Digital equipment for the shaft platform doors position control allows automatic and safe control in real-time of the hoist for the shaft-sinking process. The very difficult tasks of real-time control can be achieved only with a computerised automatic equipment based on microprocessors and microcontrollers. This new equipment was conceived by logical identification and synthesis of command functions using the KARNAUGH diagram method. The materialisation of logical functions is realised in programmable logic through a development system based on OMRON-PLC, type CPM2A, equipped with the adapter type MAD 11. Using the programming tool CX-Programmer of Omron Company, designated for the creation, testing and maintenance of software for PLCs, real-time ladder programs were created for the safety doors state control. This software was tested in laboratory conditions and will be implemented on a pilot installation.
