車輛的介紹 RS-485聯系電線通信電纜線在應該的場所通過雙絕緣線就能夠，但在想要有點高的環鏡下能夠通過帶屏蔽掉層的雙絞電線通信電纜線。在用到RS485聯系時，就對應的傳導各線路，主機電源（召測機器）到儀表板的485口間的電線通信電纜線總時長與信息4g信號燈傳導的波特率成正比；該總時長主要受4g信號燈的偏色并且躁聲的危害所危害。理論與實踐上RS485的傳導長差距能提升1200米，但到底應運中傳導長差距要乘以1200米，到底總時長受周圈的環鏡危害。 RS-485 communication cable in general occasion using twisted pair can be, but under the high requirement of environment can be using tape shielded twisted pair cables. When using RS485 communication, for specific transmission lines, the host (called measurement equipment) to the meter 485 ports between the length of cable and the data signal transmission baud rate inversely proportional; the length is mainly affected by the signal distortion and the influence of the noise influence. On the theory of RS485 and the transmission distance can reach 1200 meters, but the actual application in the transmission distance is less than 1200 meters, the length is influenced by the environment around. www.hejindianlan.com//www.anhdl.com 在低速行駛、短遠間距、無干涉的場所需利用傳統的雙銅絞合線，不然的話，在快速路、短線互傳時，則都要利用輸出阻抗適應(通常情況為120Ω)的RS485動用高壓低壓高壓電纜電線(STP-120Ω(for RS485 & CAN) one pair 18 AWG)，而在干涉極端的生活環境下還應利用鎧裝型雙絞攔截高壓低壓高壓電纜電線(ASTP-120Ω(for RS485 & CAN) one pair 18 AWG)。在動用RS485數據表格信息接口協議時，面對單一的互傳方式，從RS485數據表格信息接口協議到阻抗其數據表格信息移動的警報互傳所限制的較大高壓低壓高壓電纜電線尺寸與移動的警報互傳的波特率關系不大，這類尺寸數據表格信息重點是受移動的警報偏色及環境噪聲等關系所關系。的理論與實踐上，通信設備文件傳送數據率在100Kpbs及以內時，RS485的最長互傳遠間距能夠達到了1200米，但在具體用中互傳的遠間距也因電子器件及高壓低壓高壓電纜電線的互傳性狀而所不同之處。在互傳進程中需利用曾加中繼的策略對移動的警報去變成，比較多需加十個中繼，也說是說的理論與實踐上RS485的較大互傳遠間距需達到了9.6公理。如果真需長遠間距互傳，需利用網絡網絡金屬為宣傳有機溶劑，收發員兩端各加一些光電技術換算器，多模網絡網絡金屬的互傳遠間距是5~10多1公里，而利用單模網絡網絡金屬能夠達到了50多1公里的宣傳遠間距。 At low speed and short distance, without the interference of occasions can use ordinary twisted pair. On the contrary, in the high speed and long distance transmission, you must use impedance matching (generally 120 Ohm) RS485 special cable (STP-120 omega (for RS485 & can) one pair 18 AWG), and under the severe jamming environment should also use type sheathed shielded twisted pair cable (ASTP-//www.anhdl.com120 omega (for RS485 & can) one pair 18 AWG). When using the RS485 interface, for specific transmission lines, from RS485 interface to load the baud rate of the data signal transmission allows maximum cable length and signal www.hejindianlan.com transmission is inversely proportional to, the length of the data is mainly by signal distortion and noise influence the effect. In theory, the communication speed in 100Kpbs and below, the longest transmission distance of RS485 up to 1200 meters, but the actual application of the transmission distance is also due to the transmission characteristics of the chip and the difference between the cable. In the transmission process can be used to increase the relay method to amplify the signal, up to eight relay, that is, the theory of the maximum transmission distance of RS485 can achieve the 9.6 axiom. If you really need to long distance transmission, using optical fiber as the transmission medium, the sending and receiving ends of the photoelectric converters and multimode fiber transmission distance is 5 to 10 km, and a single mode fiber (up to 50 km of the propagation distance.
