X'inhuma r-raġunijiet għall-falliment tal-hard disk tal-kompjuter industrijali? Hemm żewġ raġunijiet ewlenin għall-falliment tal-kompjuter industrijali fl-ambjent normali, li huma prinċipalment maqsuma fil-problemi ta 'kwalità tad-disk innifsu u l-problemi kkawżati mill-ambjent tax-xogħol.
1. Il-kwalità tad-disk innifsu;
Dan mhux faċli li ssir distinzjoni. Biss meta tagħmel l-ewwel is-sistema ta 'kontroll, tista' tixtri prodotti tad-ditta b'reputazzjoni tajba, jew tista 'tuża softwer bħal Scandisk u Norton Disk Doctor biex tivverifika d-dehra tad-difetti tad-disk. Jekk nistgħu nbassru l-kwalità u s-saħħa tal-hard drives, dan jagħtina ħin biex nagħżlu l-hard drives u nappoġġjaw dejta importanti. L-istaff tekniku tagħna skopra softwer imsejjaħ Drive Health fuq l-Internet, li jista 'jiċċekkja l-ħajja tas-servizz tal-hard disk u jgħin lill-ħbieb biex ikunu jafu l-istatus tas-saħħa tal-hard disk minn qabel.
L-ostakli kkawżati miż-żewġ ambjenti tax-xogħol huma aktar komuni fl-aspetti li ġejjin:
1. The industrial computer has a long working time. Due to the necessity of normal manufacturing, the industrial control system of some manufacturers takes a long time to work, which brings great training to the industrial computer control system. According to Microsoft's operating system operating time report, Microsoft claims that its operating system after Windows 2000 can support long-term work, but from the perspective of actual operation, after the operating time spans over a week, the disk will be in the process of huge data exchange. A large number of data fragments are accumulated, which can easily become disk logical bad sectors, read and write failures, and slow system operation and startup. Therefore, the industrial computer can restart the industrial computer and defragment the disk on time under the conditions allowed by the manufacturing, so as to reduce the disk failure caused by the long-term work. The restart time can be determined according to the amount of data processed by the industrial computer and the manufacturing environment. It is not rigid and requires readers to try it out step by step. Judging from the author's actual experience, restarting and rectifying the industrial computer once a standard month (30 days) can reduce the chance of disk failure.
2. The temperature inside the industrial computer is too high. In an environment that requires a long period of high temperature operation, the components of the computer are prone to aging, and the frequency of hard disk failure is also higher. This requires the manufacturer's automation system guards to pay close attention to the chassis temperature during normal inspections, although the temperature of the industrial computer is kept between 10-30 degrees Celsius, too high and too low temperatures are not suitable for hard disks. Guard, if the case temperature reaches 30 degrees Celsius, the temperature of the hard drive inside will reach 40 degrees or higher. We can briefly DIR our industrial computer to achieve the effect of lowering the ambient temperature. 1. Replace the high-power CPU and hard disk fan (the hard disk fan should be kept unchanged, it should not be installed on the hard disk firmware frame to prevent the hard disk from being touched due to the fan rolling) to accelerate heat dissipation; Electric fans to increase air convection; 3. Install a small axial fan on the cabinet where the industrial computer is arranged; 4. Install air conditioners in the control room to lower the space temperature.
3. The ambient humidity is not suitable. The industrial computer is mainly composed of integrated circuits of many electronic components, and its insulation performance has a great relationship with the environmental humidity. If the humidity is too large, it will easily become a short circuit of the circuit board and destroy it; if the humidity is too small, it will easily generate static electricity, and it will also break down one-sided electronic components. Therefore, if the humidity is too large or too small, the city will bring potential threats to the industrial computer. On the subject of electrostatic protection, we must have good instrument grounding on our industrial computer. It is worth affirming that, the difference between the grounding of the industrial computer and the lightning protection grounding in civil construction, the grounding site should be three meters away from the control room, and the ∮20 galvanized angle steel should be used as the vertical and crisp ground at 1700 mm under the outdoor floor. The number of grounding resistance is less than 1 ohm (try the shaker when backfilling), and then use 40404 galvanized flat steel and the grounding body to be reliably welded (each welding point should also be carefully rust-proof), and then assign it to the equipment Connect the 25mm copper cable to the system ground terminal and the address of the industrial computer. This can effectively reduce the risk of static electricity.
4. Terremoti kbar jinħassu. Bosta manifatturi jeħtieġu li l-mutur jipproduċi tkaxkir, mess u movimenti oħra ta 'spostament fiżiku, li mhux biss iġibu ħsejjes enormi, iżda wkoll il-mess miġjub mill-operazzjoni mekkanika se jġib ostakli kbar għad-diska, drajv ottiku u floppy drive tal-kompjuter industrijali . It-teknoloġija tal-manifattura tad-disk qed issir dejjem ogħla, u l-veloċità attwali laħqet 7200 dawra kull sekonda jew saħansitra ogħla. Fl-iskambju ta' data-skala kbira fis-sistema ta' kontroll awtomatiku, id-diska ta'-ħin twil, b'veloċità għolja-faċilment attivata mid-diska, u tikkawża li l-ħila tal-qari u tal-kitba tad-diska tonqos , il-pożizzjoni tar-ras hija bil-mod, u anke d-diska hija bil-ħsara; b'hekk jitnaqqas l-ambjent tal-kompjuter industrijali. Ix-xokk huwa tajjeb għall-protezzjoni tad-disk. Nistgħu nippruvaw nagħmlu l-almu tagħna biex inżommu l-kompjuter industrijali 'l bogħod mis-sit tax-xogħol b'sors kbir ta' terremot waqt l-ippjanar tal-inġinerija; jekk l-indirizz tax-xogħol ma jistax jinbidel, nistgħu wkoll inqiegħdu sponoż u oġġetti li jtaffi taħt il-kabinett tal-kontroll industrijali u l-kaxxa biex inaqqsu t-tmiss ir-riskji maħluqa.
5. Hemm ħafna partiċelli li jittieħdu man-nifs fl-atmosfera. Ħafna mill-materja prima ta 'ħafna manifatturi jeħtieġ li jiġu pproċessati b'materjali tat-trab. Barra minn hekk, l-atmosfera esterna hija attiva ħafna u hemm ħafna ramel u trab. Ammont kbir ta 'trab li jwaħħal huwa faċilment akkumulat fil-kompjuter industrijali, li jikkawża li t-temperatura ġewwa l-kompjuter industrijali tkun għolja wisq, li tirriżulta f'ħsara tal-hardware. . Dan it-tip ta 'ambjent iseħħ l-aktar madwar fannijiet tat-tkessiħ bħal CPU, provvista ta' enerġija, hard disk, u karta grafika. F'postijiet b'akkumulazzjoni ħafifa ta 'trab, fl-ambjent permess mill-produzzjoni normali, huwa possibbli li jonfoħ it-trab fil-ħin. F'postijiet fejn l-akkumulazzjoni tat-trab hija relattivament għolja, il-garża tal-filtru tat-trab tista 'tiġi installata fiż-żona tal-ventilazzjoni tax-chassis tal-kontroll industrijali u mnaddfa skont l-iskeda.
6. Il-vultaġġ tal-provvista tal-enerġija jvarja ħafna u huwa suxxettibbli għal qtugħ tal-enerġija. Bl-iżvilupp mgħaġġel tal-industrija u l-ħajja, id-domanda għall-elettriku qed tiżdied ukoll jum b'jum. F'ħafna oqsma, iseħħ l-ambjent ta 'provvista ta' enerġija insuffiċjenti, vultaġġ instabbli u qtugħ ta 'enerġija faċli. Vultaġġ mhux stabbli u nuqqas ta 'enerġija f'daqqa jikkawżaw li s-sistema terġa' tibda ta 'spiss, u l-fajls tas-sistema jintilfu faċilment u ma jistgħux jinbdew b'mod normali; ir-ras manjetika li qed twettaq l-operazzjonijiet ta 'qari u kitba tista' kultant issir il-projbizzjoni tar-ritorn tar-ras minħabba n-nuqqas ta 'enerġija, li tikkawża l-falliment tad-diska tal-kompjuter industrijali. . Għalhekk, il-konsolidazzjoni tal-provvista ta 'enerġija fl-ambjent tax-xogħol tal-kompjuter industrijali hija relatata ma' jekk ix-xogħol tal-kompjuter industrijali huwiex normali jew le. Nistgħu nużaw provvista ta 'enerġija regolata u provvista ta' enerġija mingħajr interruzzjoni UPS għall-protezzjoni. L-għażla dettaljata tat-tagħmir tiddependi fuq id-daqs tal-qawwa tat-tagħbija u t-tul tax-xogħol.
