Study Of Network-Based Monitoring Technology On NC Machining State

qFollowing with the development of the calculator network and communications to develop soon, the automation technique facing intelligence turn, information based and network turn. In high automation, height complicate, highly gather become turn of modern process, the controls appearance of the tool machine to carry on the monitor, can actually the real-time obtain the spot movement appearance of the equipments, and provide the thoroughly data to the governor, support to establish production homework plan. For guaranteeing the modern machine manufacturing system of process the safety of the equipments and the work piece automatically, avoid the important trouble, raise the rate of production and the tool machine utilization, the control process appearance information of the equipments to carry on monitoring seem to be very important. This text is based on the analytical foundation of the function model analysis and the system function requests that the first floor equipments circulate up, set up the number that a network turn controls to process the equipments movement appearance monitor system. This monitor system adopts the spot bus technique and configuration control technique to control to the process equipments appearance availably. The bus of the spot is an industry network developed in the last few years, it make the automatic control system and equipments into the information network as the business enterprise information network of first floor, thus carry out the business enterprise information to gather provided the viable foundation with comprehensive automation of business enterprise. The monitoring part of the system assurance the main work appearance on operate the front panel, adopt the long-distance data collects module piece to collect the appearance signal. The bus of PROFIBUS can complete to collect the module piece data information to deliver, make use of the PROFIBUS-RS232/485 bus bridge and the spot equipments data to collect the module piece to connect with each other, and pass the bus proper to go together with the card conjunction lace of honor supervision calculator. Choose the PC+ the PROFIBUS net card CP5611 as the decision the station. The lord station mainly uses for system that completes each station of system's install, the plait distance, parameter enactment, and on-line monitor, the data collect with saving etc. function. The system circulates software package COM PROFIBUS that the Siemens company provided in order to the bus and on-line equipments. Choose the I/O collect the module piece to do the DP from the station. The series of ADAM5000 is according to RS485 of distribute type data collect to the control system, provide various functions, be subjected to the computer long range control, pass a set of deliver on the network of RS485.Pass the I/O module piece, can control the number equipments link the PROFIBUS and on-line, thus carry out the collect of the equipments movement appearance. The place of honor machine passes to circulate software MCGS to carry on the processing to the equipments appearance information collected, complete the manifestation, reporting to enunciator, statistics to print the exportation with the statement etc. function. The window way can be clear to show various data information: The spare parts quantity in one hour, one day, one month, the tool machine supervise and control total time, tool machine of the system movement switch on each time, return at the same time with indicator of clear or dark to show the each switch quantity of appearance: The tool machine switch on, the tool machine shut down, the procedure circulate, procedure be over, the tool machine change the knife, procedure edit, the principal axis blows the scraps, the oil spirit lubrication.The real time database of MCGS is the core of the system circulates. Each part connects with the real time database as the uses area, carries on the data commutation. The data deliver to the database after...
