Project Description：Hebei Kailuan Coal Mine is the largest coal mining enterprises. Mine hoisting equipment in coal mine safety and efficiency play an important role in production, both employees of the underground transport, or mention coal, cutting, transporting other mechanical equipment are inseparable from mine hoist system, you can say mine hoisting system of coal production throat, directly restricts the efficiency and level of coal production. Siemens PROFIBUS system openness, compatibility, integration of different vendors' products can be easily integrated into the control system, enables high-speed, high-precision hoist trajectory control.

Project proposals：　To enhance the use of PROFIBUS-DP PROFIBUS-DP network control system, consists of the following components:
(1) The system master station uses industrial control computer with PROFIBUS communication card. Communication card using Siemens CP5611 products.
(2) The system bus for communication using PROFIBUS-DP, the transfer rate IPC and all field devices and instrumentation to 1.5Mbps. Use of easy control of YFPB series protocol type PROFIBUS bus fiber optic repeaters, the transmission medium by the cable is converted to fiber-optic communications, completely shielding electromagnetic interference and the achievement of long-distance communication, and ensure that the system structure of the redundant ring network via high reliable operation ʱ??
(3) Distributed I / O using Siemens ET-200M From Slave and I / O modules, according to system needs to mount a standard signal module from the station. Such as: digital input modules, digital output modules, analog input modules, analog output modules.
(4) field instrumentation including ore bin level sensor, speed sensor, temperature sensor, etc., using conventional instruments connected to the I / O input from an analog station module.
(5) optical encoder for detecting the operating state of the hoist and hoist as process control.
(6) the implementation of components including fans of start and stop; hydraulic station start, stop and build pressure; transmission parts output mode, console the ordinary actuator is connected to the I / O switch stations and analog outputs from the module on.
