Each block is controlled by a, different set of codes, with the results observed by the output, tags. Two complete revolutions move the thimble 0.050 inch, 3 revolutions 0.075 inch, and 4 revolutions 0.100 inch (1/10 inch). Then compress the legs nearly to the correct measurement and tighten up on the adjusting screw, checking and adjusting until one leg stands exactly in the center of the 1-inch graduation and the other leg in the exact center of the 4-inch graduation. The input modules SM, 1231 AI from slot 102A6 to 102A8 (see Fig. The surface of the part to be tested is then rubbed on the surface plate. The wheel is used when it is desired to find the speed, in feet per minute, at which the surface of a piece of work is moving. 183? This paper is practical design and implementation of open architecture ship control, alarm and monitoring system using Supervisory Control and Data Acquisition (SCADA) .Modern ships have an automatic system control which includes control, alarm and monitoring system that have access to all process control station and can monitor them. The use of chalk is also helpful when using dividers. One side of a steel rule is ordinarily graduated in 8ths and 16ths and the other side graduated in 32nds and 64ths, as shown in Fig. The sounding rod should be scrutinized carefully for water, and if its presence is detected, it may very well indicate that a leak has developed in the tank since the last measurement was taken. Before using a scriber it is advisable to examine the point, as it must be sharp and evenly ground. As the thimble is turned, each time a graduation on the thimble passes the revolution line on the barrel, the micrometer opens or closes 0.001 inch. The points. Then carefully examine the vernier scale, Fig. Give the measurements indicated by each of the 9 examples shown in Fig. high-priced materials are scarce. In summary, the following contributions are made: the technique serves two, purposes – both monitoring and fault diagnosis; it is capitally, cheap, yet a reliable technique; all the communication proceeds, alarm record list for future fault identification. The design method employs PLCs and SCADA-based system and adopts certain basic design requirements of alarm monitoring system presented in literary works. Also, always hold the frame stationary and adjust the tool by turning the thimble. © 2008-2020 ResearchGate GmbH. When it is necessary to measure the depth of a hole, a depth micrometer can be used, as shown in Fig. At the same time, configurations, for the handling of non-normalized floating point values were, was then added to the channel, and all tags including analog, and digital tags, with their appropriate data types were added, to the OPC server. The secret of checking clearances accurately is the ability to "feel" the tension on the blade when it is moved back and forth in the space that is being measured. The surface plate can also be used for testing machine and engine parts that are required to have fiat surfaces. Scriber.-A well-sharpened scriber is used to make clean and narrow lines on metal. 181, is sometimes used aboard ship. The width of the rectangular piece in Fig. From an electrical perspecti, appropriate to protect circuits in order to ensure safe operation, of the PLCs and field I/O devices. It is often helpful to measure from the 1-inch graduation, as demonstrated in the illustration, instead of. This limitation is peculiar to the voltage measure-, ments. Be sure that both the rod and micrometer head are thoroughly clean, and that the rod is screwed in the full distance. then withdrawn from the hole and the diameter of the ball end measured with a micrometer. The functional block diagram and the logical codes, behind the blocks are shown for the monitored voltages/current, (“power station“) in the codes of Fig. When working with the larger micrometers in cold weather, it is good practice to use a piece of cloth or waste between the hand and the frame, as the heat of the hand may expand the frame enough to cause a variation in the reading. The telescoping gage should. The various units of measurement are taken up in the mathematics lessons, and the student should be thoroughly familiar and able to work with such units. By placing the base of the protractor on a line, with the midpoint of the protractor where a second line intersects the first line, the angle between the two lines can be read directly from the instrument. 153. 172 a 1-inch micrometer is used because the material is less than 1 inch in thickness. screws are tight. it can be gripped in the middle, where it is knurled for that purpose. When the thimble of a micrometer has been turned sufficiently to uncover exactly 8 graduations on the revolution line of the barrel, what distance has the spindle moved? The monitoring system can record any alarm status and save it in hard disk or printer with time stamp. across the internet to other off-site bases. from Kelvin to degree celsius, from atm to Kpa, etc. Guard against rough usage that may cause nicks or scratches, as these reduce accuracy. To do this, a thin film of Prussian blue or some other color pigment is spread evenly over the surface plate. An example of this type of reading is shown in Fig. Finally, an example is presented to validate the effect and validity. This is followed first by a consideration of the factors which affect the behaviour of fuses, and then details are given of the type-testing and quality-assurance procedures that are employed to establish performance characteristics and ensure consistency in production. The proposed design technique, including fault diagnostic algorithm, have been subjected to real-time online testing at the shipyard, specifically ChangjiangWaterway Bureau, China (ship name-Ning Dao 501). denoting the number of threads per inch. The total reading of the indicator, for 1 minute, is therefore divided by 2, and the result is the speed of the surface of the work, in feet per minute. Although several design techniques have been proposed, all the proposed design methods employ sophisticated and expensive approaches in resolving alarm issues. In such a case, when the sounding rod is removed from the tank, small bubbles would be observed on the portion of the rod that extended into the water. Calipers.-Calipers are used for measuring diameters and distances or for comparing distances and sizes. Environment Modelling for Simulation-Based Pipeline Design in Engine Room, A Study on Minimum Weight Design of Horizontal Corrugated Bulkheads for Chemical Tankers, The Vital Role of Sensors in Aircraft Engine Monitoring and Control. The. 176, and the two different readings show that it is read like other micrometers, except that the numbers on the barrel increase toward the left instead of toward the right. The split-ball type of small-hole gage, Fig. be adjusted in the work until it exactly touches points directly across from each other, and is then locked by turning the stem. The shortfall of this design method is, that, it only performs monitoring purposes, and ignores basic, error detection algorithms. The set consists of four series of sizes, as follows: 2. 185. Computational Intelligence and Informatics (SACI ’09), At Timisoara, control and data acquisition SCADA systems, thesis, Naval postgraduate. 147, also a smaller solid square. It is recommended that the sounding rod, or other arrangement lowered into a sounding pipe, be made of brass or bronze rather than of iron or steel. It is used to enable a perfectly straight line of considerable length to be marked across a flat surface. Of those who have already experienced, most of them don’t have enough confidence to carry out the D’carb alone or are reluctant to take the responsibility without the assistance of a senior personnel. up communication mechanism in case of a network failure. When the straightedge rests evenly on both coupling halves in all four tests and the clearance between the coupling halves is equal in all measurements, the coupling is properly aligned. Then slip the correct tip over the end of the spindle and apply the tip to the rotating shaft. In the ullage method of measuring the depth of liquid in a tank, a cup-shaped weight is lowered until the weight comes into contact with the surface of the liquid. A number of small rule sections are provided as a set, with a long-handled holder. Fluid levels were monitored using pressure sensors, by taking, a continues pressure measurement from the bottom of the, tank or point where the sensor’s diaphragm is placed. This sec-, tion records the faults and interfaces them according to date, and time of the occurrence.
