The performance measurement data acquisition method of CN1545259 compartment system comprises following treatment step: the first step: the initialization of principal and subordinate's processor; Second step: master processor begins collecting performance data also respectively to respectively sending acquisition from processor; The 3rd step: respectively send to master processor from processor collecting performance data and group bag; The 4th step: master processor backs up all sampled datas in this cycle, and will unify the buffer zone zero clearing, begins the measurement count of following one-period; The 5th the step: if master processor on report timer T3 overtime to the backstage, then master processor carries out sending to the backstage after the statistical computation to T3 all sampled datas in the cycle, forward to again second the step, otherwise directly forward to second the step.Improved stability, the reliability of data transmission of inlaid distribution system, reduced influence other business modules.
The monitoring and protecting of rotating machinery is based on sensor technology and technique of dynamic measurement; with the signal processing technology is the routine techniques developing stage of means; it is along with sensor technology; development of electronic technology, the collection and the processing that have solved multiple signals such as vibration, noise, power, temperature, electricity, magnetic, light substantially.And in engineering, obtained application.
Typical status monitoring mode is seen, mainly contains following several: (1 off-line periodic monitoring mode.The tester regularly to on-the-spot with the single-sensor of stipulating successively to each measuring point test, record, data processing is finished on the special purpose computer or on the instrument at portable embedded micro-processor.This is the mode that current import monitoring instrument generally adopts.Adopt this mode, test macro is simple, but needs the special messenger to operate; Owing to be the off-line periodic monitoring, handling failure in real time.(the monitoring mode of 2 online detections, off-line analysis.Also claim principal and subordinate's machine monitoring mode, a plurality of sensors of the installation on monitored equipment carry out the data acquisition and processing (DAP) of each measuring point by on-the-spot slave system, are analyzed by the professional on host computer system and judge.This modes that adopt in recent years on large rotating machinery more.Relative first kind of mode, this mode have been removed the trouble of replacing measuring point from, and can monitor in real time and report to the police.But data analysis and judge and can not handle in real time, and analysis and diagnosis need the professional to bear.The product of the 2nd kind of monitoring mode is mainly reflected in: the many employings of existing monitoring product 8 or 16 bit processors or PLC on the market; the PLC display and control unit of passage has been proposed to increase as Chinese patent 200520072551.5 rotating machinery on-line monitoring protective devices; every road signal is equipped with independently constant current output and live signal output TMD; comprise speed probe; current vortex sensor; displacement transducer; vibration transducer, and be provided with corresponding tach signal treatment circuit; axial displacement signal treatment circuit and corresponding A/D change-over circuit; vibration signal processing circuit and corresponding A/D change-over circuit; stroke signal treatment circuit and corresponding A/D change-over circuit.Speed probe connects the tach signal treatment circuit, treatment circuit connects the PLC input port through counting circuit, the output of current vortex sensor connects the axial displacement signal treatment circuit, comprise a differential amplifier in the axial displacement signal treatment circuit, sensor signal connects an input end of differential amplifier, the negative input end of differential amplifier circuit connects adjustable voltage division circuit, displacement transducer connects the stroke signal treatment circuit, and being provided with the screen displaying controller, the screen displaying controller is connected with the interface of PLC microprocessor.Because processor speed, performance, do not support reason such as operating system, the work of each monitoring channel of monitoring device can not unified management, analyzes and judges.Communicate by letter with RS485 though can carry out data acquisition, do not possess telecommunication, the function of data management.Can not support online trouble analysis system.Because processor performance is low, can not support graphic presentation equally, cause performance easy to operate good inadequately.
But the automatic on-line monitoring mode of rotating machinery is the duty of on-line monitoring slewing not only, carries out failure prediction in real time, and can carry out on-line data analysis and diagnosis by computing machine according to the data handling system storehouse of storing in advance.And judge.The operator of medium schooling can grasp using method.This mode technology is most advanced, does not need special tester, does not also need the professional to participate in analyzing and diagnosing.But the development work amount of software and hardware is very big.But be badly in need of function and reliability now, have very powerful monitoring and protecting system.
