Design And Implementation Of Remote Data Acquisition And Transmission Based On Distributed System

Remote data acquisition and transmission system is used for real timemonitoring for coal mining equipment work state, and transmitting thecollected data the the production scheduling center, which change thesituation that the drivers report orally to dispatching center and thedispatchers is not sure for the equipment. when equipment is not work,maintenance personnels can’t fully understand and diagnose fault on theground, and they have to check the status excavator field, and then therelevant maintenance personnels replace parts, which extends themaintenance time, reduces the maintenance efficiency and influences theproduction efficiency. The system transfers the equipment operatingstatus, technical parameters and fault information remotely to thecontrol center. Thus,the dispatcher can master the working status of theequipment by monitoring system, and maintenance personnel can analyze themalfunction remotely, which can make maintenance decision quickly, andwhich improve the work efficiency of the equipment.The system can provide the data for equipment maintenance personnelby the installation of data acquisition terminal on the device, using theexisting transmission network transmit the collected data to the databaseserver, and access on the Web server to realize the data display indispatching center PC terminal. System uses the distributed technology,network communication technology, software engineering technology andelectronic design technology, realize the remote data acquisition.Thesystem can realize data acquisition of intelligent monitoring instrument,compatible with a variety of monitoring instrument of communicationprotocol, and make the monitoring and acquisition point deployed flexibly.The increase or decrease of acquisition point will not affect theexisting system. The monitoring process is independent of equipment, andit is stability and from the effects of other factors. The system follows RS485standards, industrial Ethernet standards.Also,it uses theindependent TCP/IP protocol,and applies the mature distributedtechnology, which can establish data collection and transmission systemof high security, strong compatibility, high transmission efficiency forthe enterprise.The system can display the working state, technical parameters andfault information of equipment through the Agent data acquisition, whichprovides accurate data for maintenance personnel, reduces recovery timewhen the equipment is failure, improves production efficiency for theenterprise, and also verifies the availability of the system.
