Monitoring data collection system

The rapid development of microelectronics has enabled many similar measurements to be made with data collecting systems and then stored electronically. The raw data can then be downloaded to the data processing installation, where they can be plotted and evaluated at any time [1]. This applies particularly to monitoring measurements on pipelines for intensive measurements, see Section 3.7. Figure 3-1 shows an example of a computer-aided data storage system. 

The modern analytical laboratory employing instrumental chromatography uses a computer data collection system and associated software to acquire the data and display the chromatogram on the monitor. Parameters important for qualitative and quantitative analysis, including retention times and peak areas, are also measured and displayed. The software can also analyze the data to determine resolution, capacity factor, theoretical plates, and selectivity. 

A water quality analyzer may be as simple as a probe inserted into the water and connected to a conveniently located recorder or as complex as a data collection system with multiple sensors distributed in several locations and provided with wired or wireless connection to a centralized data-com-piling system. Trace concentrations of components are monitored in drinking, industrial, and ultrapure water. 

The Quality Assurance organization has no mandated role in the development of computer systems other than defining QA fnnctional reqnirements. Once the system has been validated, accepted, and installed, QA will be responsible for monitoring data collection until its reliability is confirmed in accordance with SOP, compliance of nser SOPs, training, and secnrity policies. Any performance problems shonld be commnnicated to the responsible management persotmel in a timely fashion. QA shonld monitor corrective actions and nnschednled downtime records. 

An automated data collection system (DCS) of approximately 6(XX) channels continuously records the readings of the various sensors on an hourly basis. The DCS scans and records the readings of temperature, humidity, pressure, MPBXs, strain gages, convergence monitors, and current and voltage for heater power. The measurements made by the DCS are referred to as passive monitoring. Other measurements such as ERT, neutron logging, GPR, acoustic emissions, REKA probe, and others are made periodically (every few weeks to few... 

Two other computer facilities are a data collection system which monitors remotely located data acquisition and experiment-control computers via asynchronous serial lines and the two Evans and Sutherland LDS-1 interactive graphics terminals. A PDP 10 included in the network configuration as an alternate file transport concentrator and auxiliary network development machine also performs the role of worker computer with the Evans and Sutherland display equipment. Other subnetworks have been designed for inclusion in the Octopus network to direct the on-line operation of LLL high-speed printer and microfilm recorder output facilities, to administer a second, expanded television monitor system providing 256 channels of video input for distribution to 512 additional monitors, and to control a CDC on-line tape library of 8.7 x 10 bits scheduled for delivery in 1975. The Computer Hardcopy Output Recording System (CHORS) concentrators are two Modcomp II computers, and TMDS-II will utilize two PDP 11/45s both subnetworks are to become operational during the... 

The platform should support automatic, semi-automatic and manual matching of data collection methods. For enterprises with comprehensive data acquisition conditions, support automatic monitoring system installed in workplaces, automatically obtain the relevant occupational hazard data, and real-time, reliable, convenient transmitted to the monitoring center, connect to the network server to receive and enter the occupational hazards regulatory information the database server of the system to achieve real-time monitoring of the occupational hazards source-to-multipoint (occupational hazard source monitoring points) state parameters (central station). With some data collection capabiUties but can not work on-site networked enterprise, support for portable mobile device to import data enterprises do not have the data acquisition conditions, you can use the manual entry of data collected system data. 

The original design for TIP includes neutron detector and collecting information, however in the market were available an automatic TIP with Gamma detector, using computerized automatic data collecting system, that makes faster the total core power range monitor calibration, and faster startups. This concept improves the capacity factor of the plant. 

Whenever possible, monitoring indicators should be derived from administrative data generated by the program, as this information has a comparatively low marginal cost. Such data are cheap whenever such records exist or can be readily modified. They are also more likely to be used by program personnel as they are familiar with the data collection system and with the procedures for transforming raw data into indicators. 

The remote data collection system allowed the tractor operations performed to be monitored in real time and in a remote position from the field work, demonstrating that the communication system adopted meets the requirements inherent to agricultural tractor operations. 

Put the activity monitors into the incubator and connect them to the data collection system. 

The monitoring software for every system will be different. However, all software is there to achieve one goal—it must gather data, ensure that it is correct, and then analyze and diagnose the data. Presentations must be in a convenient form and should be easily understood by plant operational personnel. All priorities must be to the data collection process. This process must not in any manner be hampered since it is the corner stone of the whole system. 

Although each of the commercially available computer-based vibration monitoring systems has unique features and formats, the information contained in this chapter is applicable to all of the systems. However, the manual provided by the vendor should be used in conjunction with this chapter to ensure proper use of the microprocessor-based data collection analyzer and the computer-based software. 

The exposure of sensors in a by-pass stream (which can be valved off), is an alternative way of collecting monitoring data although correlation is required between the main-stream and the by-pass The use of a side-stream taken either side of a choke in the main-stream can provide a useful monitoring point. Traps where product streams can be condensed can offer alternative sampling systems. 

The traditional arrangement of simple spherical glassware and Isomantles with full-power on-off controllers monitored by mercury thermometers, would still be widely recognised. So too would be the plug-shot piston pumps set up and monitored by use of measuring cylinders. Although tried and tested this hardware system requires constant attention by a skilled lab. technician to achieve control and reproducibility of even the first-order process parameters manual data collection is hardly feasible at better than 10-15 minute intervals. 

A simplification of the polarization resistance technique is the linear polarization technique in which it is assumed that the relationship between E and i is linear in a narrow range around E . Usually only two points ( , 0 are measured and B is assumed to have a constant value of about 20 mV. This approach is used in field tests and forms the basis of commercial corrosion rate monitors. Rp can also be determined as the dc limit of the electrochemical impedance. Mansfeld et al. used the linear polarization technique to determine Rp for mild steel sensors embedded in concrete exposed to a sewer environment for about 9 months. One sensor was periodically flushed with sewage in an attempt to remove the sulfuric acid produced by sulfur-oxidizing bacteria within a biofilm another sensor was used as a control. A data logging system collected Rp at 10-min intervals simultaneously for the two corrosion sensors and two pH electrodes placed at the concrete surface. Figure 2 shows the cumulative corrosion loss (Z INT) obtained by integration of the MRp time curves as ...
