一、通信設備包括哪些

通信設備是用于工控環境的有線通訊設備和無線通訊設備，大致可分為有線通訊設備和無線通訊設備兩種。有線通訊設備主要解決工業現場的串口通訊，專業總線型的通訊，工業以太網的通訊以及各種通訊協議之間的轉換設備，包括電腦、 電視、電話、PCM、光端機、服務器、路由器、交換機、modem等設備；無線通訊設備是利用電磁波信號在自由空間中傳播進行信息交換的設備，有無線AP、無線網橋、無線網卡、無線避雷器、天線、衛星、無線電臺、無線電視（公交車或地鐵上）、無線局域網、移動電話（手機）、手機GPRS上網等設備。如果您需要購買通信設備，可以先來了解一下通信設備十大品牌。

二、通信設備的作用是什么

通(tong)(tong)(tong)信(xin)設備分為有線通(tong)(tong)(tong)信(xin)設備和無線通(tong)(tong)(tong)信(xin)設備，有多(duo)種(zhong)類型，不(bu)同種(zhong)類的(de)通(tong)(tong)(tong)信(xin)設備作(zuo)用會略有不(bu)同，一(yi)般總(zong)的(de)來說，其作(zuo)用是解決工(gong)業現場的(de)串口通(tong)(tong)(tong)訊、實現專(zhuan)業總(zong)線型的(de)通(tong)(tong)(tong)訊、工(gong)業以太網的(de)通(tong)(tong)(tong)訊以及各種(zhong)通(tong)(tong)(tong)訊協議之間的(de)轉換、傳輸(shu)數據等(deng)。

三、通信設備故障檢測方法有哪些

1、直接(jie)觀察(cha)法(fa)(fa)：直接(jie)觀察(cha)有(you)(you)不接(jie)電(dian)(dian)(dian)(dian)(dian)和(he)(he)接(jie)電(dian)(dian)(dian)(dian)(dian)兩(liang)種情況，首先(xian)應該進行不接(jie)電(dian)(dian)(dian)(dian)(dian)觀察(cha)，利用(yong)人的感覺器官檢(jian)(jian)(jian)(jian)(jian)(jian)查(cha)(cha)(cha)(cha)，確(que)認機(ji)內外各元器件(jian)(jian)無(wu)誤后(hou)，接(jie)電(dian)(dian)(dian)(dian)(dian)觀察(cha)，看機(ji)內有(you)(you)無(wu)冒煙、打火(huo)、異常(chang)聲響現(xian)象(xiang)，如有(you)(you)趕(gan)緊關機(ji)，還(huan)可(ke)輕(qing)輕(qing)敲擊機(ji)箱(xiang)、構件(jian)(jian)，看有(you)(you)無(wu)接(jie)觸不良，同(tong)時可(ke)用(yong)手觸摸懷疑的元器件(jian)(jian)，看是(shi)否(fou)有(you)(you)過熱現(xian)象(xiang)并根據(ju)元器件(jian)(jian)過熱程度(du)(du)以及溫度(du)(du)做出(chu)相應的判斷。2、測(ce)量(liang)法(fa)(fa)：常(chang)見的測(ce)量(liang)檢(jian)(jian)(jian)(jian)(jian)(jian)查(cha)(cha)(cha)(cha)方(fang)法(fa)(fa)有(you)(you)電(dian)(dian)(dian)(dian)(dian)壓(ya)檢(jian)(jian)(jian)(jian)(jian)(jian)查(cha)(cha)(cha)(cha)法(fa)(fa)、電(dian)(dian)(dian)(dian)(dian)阻檢(jian)(jian)(jian)(jian)(jian)(jian)查(cha)(cha)(cha)(cha)法(fa)(fa)和(he)(he)電(dian)(dian)(dian)(dian)(dian)流檢(jian)(jian)(jian)(jian)(jian)(jian)查(cha)(cha)(cha)(cha)法(fa)(fa)。電(dian)(dian)(dian)(dian)(dian)壓(ya)檢(jian)(jian)(jian)(jian)(jian)(jian)查(cha)(cha)(cha)(cha)法(fa)(fa)是(shi)通過測(ce)量(liang)元器件(jian)(jian)工作電(dian)(dian)(dian)(dian)(dian)壓(ya)并與正常(chang)值進行比較來判斷故(gu)(gu)(gu)障(zhang)；電(dian)(dian)(dian)(dian)(dian)阻檢(jian)(jian)(jian)(jian)(jian)(jian)查(cha)(cha)(cha)(cha)法(fa)(fa)是(shi)測(ce)量(liang)元器件(jian)(jian)對地或自身電(dian)(dian)(dian)(dian)(dian)阻值來判斷故(gu)(gu)(gu)障(zhang)的一(yi)種方(fang)法(fa)(fa)，它對檢(jian)(jian)(jian)(jian)(jian)(jian)修開路、短路故(gu)(gu)(gu)障(zhang)和(he)(he)確(que)定故(gu)(gu)(gu)障(zhang)元件(jian)(jian)有(you)(you)實效；電(dian)(dian)(dian)(dian)(dian)流檢(jian)(jian)(jian)(jian)(jian)(jian)查(cha)(cha)(cha)(cha)法(fa)(fa)是(shi)將電(dian)(dian)(dian)(dian)(dian)流表串入(ru)電(dian)(dian)(dian)(dian)(dian)路中測(ce)量(liang)工作電(dian)(dian)(dian)(dian)(dian)流。3、插(cha)拔(ba)法(fa)(fa)：通過將插(cha)件(jian)(jian)“插(cha)入(ru)”或“拔(ba)出(chu)”來尋找故(gu)(gu)(gu)障(zhang)。4、試探法(fa)(fa)：用(yong)正常(chang)的插(cha)件(jian)(jian)板或好的組(zu)件(jian)(jian)（大規模的集成電(dian)(dian)(dian)(dian)(dian)路）替(ti)換有(you)(you)故(gu)(gu)(gu)障(zhang)疑點的插(cha)件(jian)(jian)板或組(zu)件(jian)(jian)來試探故(gu)(gu)(gu)障(zhang)。5、其它檢(jian)(jian)(jian)(jian)(jian)(jian)修方(fang)法(fa)(fa)：包括隔離(li)法(fa)(fa)、比較法(fa)(fa)、升溫法(fa)(fa)等。6、綜合法(fa)(fa)：把(ba)以上方(fang)法(fa)(fa)統一(yi)考慮起來處理(li)故(gu)(gu)(gu)障(zhang)，處理(li)一(yi)些比較復雜的故(gu)(gu)(gu)障(zhang)，能及時、準確(que)地找出(chu)故(gu)(gu)(gu)障(zhang)原因并且排除它。

四、通信設備折舊年限是多少

通(tong)信(xin)設(she)備有一(yi)(yi)定(ding)的(de)折(zhe)(zhe)舊年(nian)(nian)限，根據規定(ding)，通(tong)信(xin)設(she)備折(zhe)(zhe)舊年(nian)(nian)限一(yi)(yi)般在5-10年(nian)(nian)，運營(ying)商(shang)會(hui)采取更(geng)激進的(de)折(zhe)(zhe)舊方(fang)式，所以(yi)，可(ke)能(neng)會(hui)更(geng)接近于５年(nian)(nian)。不過需要(yao)注意的(de)是，通(tong)信(xin)設(she)備有很多不同的(de)設(she)備，設(she)備類型不同，折(zhe)(zhe)舊年(nian)(nian)限也是有一(yi)(yi)定(ding)區別的(de)。
