電視櫃改造無明線設備櫃

電視櫃通常放些什麼?

在早期電視都在看有線電視(第四台)為主的年代,大家的客廳電視下方電視櫃,總是會擺放各種設備如選台器、DVD 播放機、遊戲機、音響主機、擴大機等等…,除了每台設備都得要能被紅外線遙控(IR)之外,還得注意散熱避免設備熱當機,所以常常會看到各種電視櫃中間幾個格子開放式的設計。

早期的開放電視櫃

當這些設備都放入之後,電源線、信號線再怎麼整理都還是略嫌雜亂,而且開放式設計就會讓這些設備吃灰塵,有些會設計半透明的玻璃作為遮擋用,不過都關上之後對於散熱還是有一些影響。而我就是走眼不見為淨的路線,因此後來對於能藏的的設備我一律都把它們藏到看不到的地方像是電視正後方,如果有需要紅外線遙控時,再透過紅外線延伸器作為轉發訊號用,其餘無法藏的設備也只能放在一旁吃灰塵…。

直到終於有機會自己規劃客廳電視牆、電視櫃之後,選台器、DVD 播放機等設備早已不再需要,取而代之的是各種更方便的無線設備,能夠在這個時空背景下規劃電視櫃,算是替我這種不想看到雜亂線路的人幫了很大的忙…XD

全新規劃電視櫃安排

由於不想看到各種線路是最優先項目,因此規劃電視櫃時電視牆就直接可以與電視櫃連通,所有需要與電視連接的地方,都可以從後面走線來隱藏。

機櫃電視櫃安排

除此之外要放設備的地方也全部加上門板,但是保留下方開孔、以及蓋上後不要完全閉合保留散熱空間。

有散熱空間的電視櫃

再來是設備應該不會只用到一個櫃子,所以這些櫃子之間也要保留開孔來作為線路連通用。

清點進駐設備

接下來要放入各種設備,這些設備有些是陸續加上的,以目前撰文的時間點來看,設備會有:

  • UPS 不斷電系統
  • 中華電信數據機
  • 主要 Router (MikroTik hAP AC2)
  • 5 Port SwitchHub
  • NAS (DS218+) + 外接硬碟
  • DeskMini Windows 小電腦
  • Mac mini M2
  • GMKtec G3 Ubuntu 小電腦
  • Nintendo Switch 遊戲機
  • CC2652P ZigBee Gateway
  • 電話機

加一加其實還蠻多的,如果再加上散熱風扇、變壓器、延長線排插、還有一堆網路線,所以好好規劃這些設備的空間就變得非常重要。

設備空間準備

其實三格的空間也不是很充裕,所以要準備可以分隔成上下兩層增加空間的隔板,選用迷你的波浪架維持空氣流通散熱性,並墊高第一層的底板也是為了散熱。

波浪架分隔

接下來就在後方埋入線槽,雖然不太可能完美的把所有線都塞到線槽內,但有個線槽在還是能讓走線稍微整齊一些。

線槽

接下來就是電源的部份,因為 APC RS 1000G 體積蠻大的,預想是把所有設備的電源都經過 UPS 供電,所以放入 UPS 後就順便把後續延長線排插都從 UPS 分接出來,反正多半是一些弱電設備功率不會太高,這樣這一系列的設備都不用擔心短時間的跳電或停電。

最後散熱的部份直接透過預留的散熱孔,加上一進一出的風扇達到對流的效果,雖然不敢保證能有最好的對流效果,但是有總比沒有好…,反正真的太熱就開空調了…XD

輔助設備準備

為了能隨時監測這些櫃子內的溫度,也要裝上溫濕度監測的設備,避免風扇故障或其他原因造成溫度異常能發現,這要配合 Home Assistant 檢測紀錄,之後有空再另外分享。

溫濕度感應

為了讓機櫃裡面清楚且容易作業,當然必須加上燈光效果 XD;所以在門板上都安裝了門窗感應器,在機櫃只要打開的情況下,LED 燈就會自動點亮,以便確認內部設備狀態、走線方式等等,一樣得配合 Home Assistant 設備自動化。

打光 LED

因為設備眾多,我希望每一個設備都能精確的測量功耗,因此除了之前 全戶電力監測 之外,也會獨立把這些設備都加上單獨的電量檢測,可以知道每一台設備的實際功耗。

獨立電量監測

不同的主機

目前主機設備分別是一台 Windows(DeskMini i5-9500)、一台 Mac OS(Mac mini M2)、一台 Ubuntu(GMKtec G3),分別有不同的用途與場景,盡可能都選用體積小的設備,可以不用殼來提昇散熱效果的話就拔掉,反正蓋起來也都看不到。

主要設備

NAS 備份用

群暉的 NAS 主要用來備份用,既然是重要資料的備份,就中二的貼個「機密」貼紙…XD;外接硬碟就是要讀取一些其他冷儲存硬碟的時候方便抽換,都透過 NAS 來存取。

NAS

網路線規劃

其實一開始只用 Router 上的 5 Port,後來設備越來越多,只好又加一台 SwitchHub 作為擴充,線實在太多,就要把線頭的地方都要加上標籤方便辨識,然後也都自己做剛好的長短避免線路太亂。

線材標示

往電視的線

雖然電視後面跟機櫃是相通的,但電視內的 Google TV 就已經能播放各種來源,大概就只剩下遊戲機還是要接實體 HDMI 線路,目前也只有 Nintendo Switch,這個通道線路反而沒有想像中的多。

Nintendo Switch

電視 Sound Bar

音響的部份沒有太講究,只用了 2.1 的 MusicCast BAR 400,SoundBar 本體的部份直接跟電視合體,一樣不會有明線跑出來。

CC2652P Zigbee Gateway

最後這台 Zigbee 設備扮演了全室 IoT 設備的 Gateway,星形網路拓撲的特性,讓信號可以低功耗無死角,這台 Gateway 可以輕鬆連接上百個 Zigbee 設備,小小一台功能強大,直接反貼在上方。

目前的完工照

雖然還是有可能異動設備,不過目前應該可以符合大多數的情境,希望可以讓設備都順利的運作不要故障。

全部設備

關起來真是乾淨

這樣的規劃或許不是最好,應該也還有更完美的方案,不過如果有什麼建議或方案,也歡迎一起討論。
