Ki rezon ki fè echèk disk la nan òdinatè endistriyèl la? Gen de rezon prensipal pou echèk nan òdinatè endistriyèl la nan anviwònman nòmal la, ki se sitou divize an pwoblèm yo bon jan kalite nan disk nan tèt li ak pwoblèm yo ki te koze pa anviwònman an k ap travay.
1. Bon jan kalite a nan disk la tèt li;
Sa pa fasil pou distenge. Se sèlman lè ou fè premye sistèm kontwòl la, ou ka achte pwodwi mak ak bon repitasyon, oswa ou ka itilize lojisyèl tankou Scandisk ak Norton Disk Doctor pou tcheke aparans nan domaj ki gen kapasite. Si nou ka predi bon jan kalite a ak sante nan kondui di, sa a pral ba nou tan yo chwazi kondui di ak fè bak done enpòtan. Anplwaye teknik nou an dekouvri yon lojisyèl ki rele Drive Health sou entènèt la, ki ka tcheke lavi sèvis disk la epi ede zanmi yo konnen estati sante disk la davans.
Obstak ki te koze pa de anviwònman travay yo pi komen nan aspè sa yo:
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. Gwo tranblemanntè yo santi. Anpil manifaktirè mande pou motè a pou pwodwi trennen, manyen ak lòt mouvman deplasman fizik, ki pa sèlman pote gwo bri, men tou, manyen la te pote pa operasyon an mekanik pral pote gwo obstak nan disk la, kondwi optik, ak kondwi diskèt nan òdinatè endistriyèl la. . Teknoloji manifakti disk la ap vin pi wo ak pi wo, e vitès aktyèl la te rive nan 7200 revolisyon pou chak segonn oswa menm pi wo. Nan echanj done gwo -echèl la nan sistèm kontwòl otomatik la, tan ki long, gwo-diskèt la fasil deklanche pa disk la, sa ki lakòz kapasite li ak ekri disk la diminye. , pwezante tèt la ralanti, e menm disk la domaje; konsa diminye anviwònman an nan òdinatè endistriyèl la. Chòk la bon pou pwoteje disk la. Nou ka eseye pi byen nou pou kenbe òdinatè endistriyèl la lwen sit travay la ak yon gwo sous tranbleman tè pandan planifikasyon jeni; si adrès travay la pa ka chanje, nou ka tou mete eponj ak kalaj objè anba kabinè kontwòl endistriyèl la ak bwat pou redwi manyen risk yo poze.
5. Gen anpil patikil inhalable nan atmosfè a. Pifò nan matyè premyè nan anpil manifaktirè yo bezwen trete ak materyèl poud. Anplis de sa, atmosfè ekstèn lan trè aktif e gen yon anpil nan sab ak pousyè tè. Yon gwo kantite pousyè kolan fasil akimile nan òdinatè endistriyèl la, ki lakòz tanperati a andedan òdinatè endistriyèl la twò wo, sa ki lakòz domaj pyès ki nan konpitè. . Kalite anviwònman sa a fèt sitou alantou fanatik refwadisman tankou CPU, ekipman pou pouvwa, ki gen kapasite difisil, ak kat grafik. Nan kote ki gen akimilasyon pousyè limyè, nan anviwònman an pèmèt pwodiksyon nòmal, li posib pou kònen pousyè sou tan. Nan kote akimilasyon pousyè relativman wo, twal gaz filtre pousyè ka enstale nan zòn vantilasyon chasi kontwòl endistriyèl la epi netwaye nan orè.
6. Voltaj ekipman pou pouvwa a varye anpil epi li gen tandans fè pann kouran. Avèk devlopman rapid nan endistri ak lavi, demann pou elektrisite ap ogmante tou jou pa jou. Nan anpil zòn, anviwònman an nan ekipman pou pouvwa ensifizan, vòltaj enstab ak pann kouran fasil rive. Vòltaj enstab ak echèk pouvwa toudenkou lakòz sistèm nan rekòmanse souvan, ak dosye sistèm yo fasil pèdi epi yo pa ka kòmanse nòmalman; tèt la mayetik ki ap fè operasyon yo li ak ekri ka detanzantan vin entèdiksyon an retounen tèt akòz echèk pouvwa a, ki pral lakòz echèk la ki gen kapasite nan òdinatè endistriyèl la. . Se poutèt sa, konsolidasyon an nan ekipman pou pouvwa a nan anviwònman an k ap travay nan òdinatè endistriyèl la gen rapò ak si travay la nan òdinatè endistriyèl la se nòmal oswa ou pa. Nou ka itilize ekipman pou pouvwa reglemante ak UPS san enteripsyon ekipman pou pwoteksyon. Seleksyon an detay ekipman depann sou gwosè a nan pouvwa a chaj ak dire a nan travay la.
