Application And Research Of Communications Protocol Of Motive Object-Supervised System In Coal Mine Based On WPAN

It is important to safe and efficient supervision of Motive Object in Coal Mine security system ,it has the characteristics of discrete and real time .There is two type of fixture in Coal Mine which is fixed and motive, with the measure of wireless technology ,we can achieve the management of the motive equipment, mobile communication system in Coal Mine provides a feasible program for Motive Object-Supervision. The mobile communication system can resolve the Motive Object-Supervision with the leaky and inductive communication ,the frame and selection of framework and mode of communication is critical for safe and efficient Supervision.This dissertation studies the framework of the Supervision of Motive Object in Coal Mine with CAN and WPAN wireless technology, analyzes the characteristics of mobile communication system in Coal Mine, comparing other mobile communication system, educe the advantage of the mobile communication system using CAN and WPAN wireless technology.We put forward a new application model which use CAN and wireless network in whole, comparing the advantage and disadvantage of other communication mode, resolve the communication method from WPAN to CAN, Put the communication framework of CAN and WPAN into practice, Measuring the system off some function module by modeling design method, contrive the WMSRS BS and Short Distance Radio ,embedded software and hardware.Sorting the information and communication type in the system, devise the wireless node,transplant theIEEE802.15.4 and CAN protocol, empolder application module of conversion from IEEE802.15.4 to CAN protocol. Devise the location and supervise mode of this system ,routing method of the information in the system, resolve redundancy and collision.It is important to select framework of communication for supervision of Motive Object in Coal Mine ,the framework of communication which use CAN and wireless network in whole has the characteristics of higher security and precision ,the model is applied in the actual project and obtained good effect.
