產(chǎn)品介紹
RS-485通訊電纜在一般場合采用雙絞線就可以,但在要求比較高的環(huán)境下可以采用帶屏蔽層的雙絞電纜。在使用RS485通訊時,對于特定的傳輸線路,主機(召測設(shè)備)到儀表的485口間的電纜長度與數(shù)據(jù)信號傳輸?shù)牟ㄌ芈食煞幢龋贿@個長度主要受信號的失真以及噪聲的影響所影響。理論上RS485的傳輸距離能達到1200米,但實際應(yīng)用中傳輸距離要小于1200米,具體長度受周圍的環(huán)境影響。
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.comhttp://m.zscmsdcq.com
在低速、短距離、無干擾的場合可以采用普通的雙絞線,反之,在高速、長線傳輸時,則必須采用阻抗匹配(一般為120Ω)的RS485專用電纜(STP-120Ω(for RS485 & CAN) one pair 18 AWG),而在干擾惡劣的環(huán)境下還應(yīng)采用鎧裝型雙絞屏蔽電纜(ASTP-120Ω(for RS485 & CAN) one pair 18 AWG)。在使用RS485接口時,對于特定的傳輸線路,從RS485接口到負載其數(shù)據(jù)信號傳輸所允許的最大電纜長度與信號傳輸?shù)牟ㄌ芈食煞幢,這個長度數(shù)據(jù)主要是受信號失真及噪聲等影響所影響。理論上,通信速率在100Kpbs及以下時,RS485的最長傳輸距離可達1200米,但在實際應(yīng)用中傳輸?shù)木嚯x也因芯片及電纜的傳輸特性而所差異。在傳輸過程中可以采用增加中繼的方法對信號進行放大,最多可以加八個中繼,也就是說理論上RS485的最大傳輸距離可以達到9.6公理。如果真需要長距離傳輸,可以采用光纖為傳播介質(zhì),收發(fā)兩端各加一個光電轉(zhuǎn)換器,多模光纖的傳輸距離是5~10公里,而采用單模光纖可達50公里的傳播距離。
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-http://m.zscmsdcq.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.
