淺談數字對講機較模擬對講機的優點

無線電對講機在設計技術方面，可分為模擬通信技術的模擬對講機（也就是我們常見的傳統對講機）以及採用數碼技術進行設計的數字對講機。模擬對講機是將儲存的信號調製到對講機傳輸頻率上，而數字對講機則是將語音信息數字化，以數字編碼形式傳播，也就是對講機傳輸頻率上的全部調製為數字。數字對講機具有語音抗干攏能力強、語音清晰、保密性高、信道佔有帶寬更窄、傳輸數據能力更強等顯著優點。

一、傳統的模擬對講機是將語音、信令、信號以連續波方式調製到對講機載頻上並經過放大等優化處理的一種通訊模式，具有技術成熟、系統完善、成本相對低等優點。

二、數字對講機是將語音信號數字化，以特定的數字編碼方式和特定的基帶調製形式，並採用數碼訊號處理器進行優化的數據化通訊模式。

首先，可以更好地利用頻譜資源。與蜂窩數碼技術相似，數字對講機可以在一條指定的信道上裝載更多用戶，提高頻譜利用率，這是一種解決頻率擁擠的方案。

其次，提高通話質量。由於數字通信技術擁有系統內錯誤校正功能，和模擬對講機相比，可以在一個範圍更廣泛的信號環境中，實現更好的語音音頻質量，其接收到的音頻噪音會更少些，聲音也更清晰。

第三，提高、改進語音和數據集成，改變控制信號隨通訊距離增加而降低的弱點。與類似集成模擬的語音及數據系統相比，數字對講機可以提供更好的數據處理及界面功能，從而使更多的數據應用可以被集成到用一個雙向無線通信基站結構中，對語音和數據服務集成更完善，更方便。

隨着無線電通信技術的發展，人們對無線通信質量要求的提高以及頻譜資源的日益缺乏，數字對講機必將有巨大的市場需求。目前，在國內的數字對講機的需求也在不斷增加。

對講機的使用應注意

每當開機時應檢查使用的信道是否正確，以免造成不必要的失誤。

使用對講機通話時，應保持對講機垂直，話筒離口部3-5厘米。

使用對講時應避免高溫、潮濕、可燃氣體等環境遠離加油加氣站。

使用對講機時，動作要輕，不要用手提對講機的天線部位，這樣很可能造成天線的損壞，影響通話。

發射時耗電量大，接聽時耗電量小，守候時要省電。

充電時，第一次充電最好超過8小時，否則影響日後的充電效率以及電池的壽命。

使用過程式中不要進行多次的開關機動作，同時把音量調節節到適合你聽覺的位置。

只能使用廠家原配或認可的天線，未經認可或經改裝的天線可能會損壞對講機或違反信息產業無線電管理委員會的規定。

對講機無線不能擰下使用，否則在發射時容易損壞其功率管。

不要使用損壞的天線，在發射時，如果損壞的天線接觸到皮膚，可能引起輕微的灼傷。

電池須用廠家原裝電池或認可的電池，且在充電時應在5-40攝氏度的環境中進行，如果超過此溫度範圍，電池的使用壽命將受到影響，同時也有可能充不滿額定容量。

避免電磁干擾或電磁兼容引起的問題，請在貼有“關閉對講機”標識的場合關閉對講機。例如醫院、機場、加油站等場所。

對講機長期使用後，按鍵控制旋鈕和機殼很容易變髒，請從對講機上取下控制旋鈕，並用中性洗劑和濕布清潔機殼。使用例如除污劑、酒精、噴霧劑等化學藥品都可能造成對講機表面和外殼的損壞。

對講機如何調頻？

人常說，兩人說話不在一個頻道上，來形容兩人各說各的，無法溝通。想要流暢溝通，自然需要調到一個頻道上。

對講機的頻率相同自然是能夠順利溝通的前提，剛了解對講機的人可能會以為只要是相同品牌就能通話，還有人會誤解不是一個品牌的對講機，就不能實現通話了，這些都是不怎麼了解對講機時會出現的誤解。

所以說只要是兩個人的對講機可以調到同樣頻率上就能實現通話了，當然對講機也有分類的，手持對講機（手台）分為專業對講機和業餘對講機，兩種調頻的方式也是不同的。

頻率怎麼調

業餘對講機相對於專業對講機來說自然簡單的多，只需要旋轉對講機上的旋鈕就可以調頻了，這些頻道都是出廠設置好了，操作簡單，一般人都能使用。

專業對講機就需要連接電腦進行調頻，通過數據線、驅動、軟件來讀寫對講機頻率

人常說，兩人說話不在一個頻道上，來形容兩人各說各的，無法溝通。想要流暢溝通，自然需要調到一個頻道上。

當兩個對講機頻率不同時，如何寫頻：

1、用數據線連接電腦和對講機，電腦上安裝KPG87D寫頻軟件；

2、打開寫頻軟件，按住Alt鍵彈出窗口，用方向鍵控制左右，按住回車鍵確認；

3、讀取數據，獲取頻點數據；

4、挑選需要的數據，讀取出來，直接覆蓋到另一部對講機上，即可實現通話了。返回搜狐，查看更多

防爆對講機

隨著時間的推移，對講機漸漸發展成為一個產業，很多人認為手機可以取代對講機，但是使用過對講機的人都知道，對講機集群調度是非常方便快捷的，溝通效率高，而且在一些易燃易爆的場合，使用防爆對講機是十分安全的。

防爆對講機

是指可以工作在爆炸性氣體環境的對講機。防爆對講機並非指自身能抵抗爆炸的對講機，而是指可以在爆炸性氣體環境下工作的對講機。適用於環境惡劣、存在危險可燃氣體或粉塵的環境如石化、煤礦、化工、火電、食品加工等行業。

如何選對講機

第一步、本質安全型電氣設備按本安電路使用場所和安全程度分為 ia和ib兩個等級：

ia等級：在正常工作、一個故障和二個故障時均不能點燃爆炸性混合物的電氣設備。

Ib等級：在正常工作和一個故障時不能點燃爆炸性混合物的電氣設備。

第二步、設備類別

I類：煤礦井下用電氣設備   II類：工廠用電氣設備

第三步、設備級別

級別： II類電氣設備，按其適用於爆炸性氣體混合物最大試驗間隙或最小點燃電流比分為A、B、C三級， A級最低，C級最高

第四步、電氣設備的允許最高表面溫度

溫度組別   允許最高表面溫度

T1             450

T2             300 

T3             200

T4             135

IP是Ingress Protection的縮寫，IP等級是針對電氣設備外殼對異物侵入的防護等級，來源是國際電工委員會的標準IEC60529，這個標准在2004年也被採用為美國國家標準。

國內相關測試依據為 GB 4208-2008/IEC 60529-2001《外殼防護等級（IP代碼）》標準要求，對各類產品的外殼防護等級進行合格評定性判定試驗；最高檢測等級IP68。常規產品檢測等級包括：IP23、IP44、IP54、IP55、IP65、IP66、IP67、IP68等級。

Quick Facts About Family Radio Service

FRS:

Family Radio Service, Approved since 1996

Frequencies:

462.56-467.71 MHz, Channels 1-7 are shared with GMRS

Uses the UHF band

Range:

FRS manufacturers generally claim an effective range of 3 km (2 miles), but actual performance varies widely on environment.

Family Radio Service (FRS) is used by family, friends and associates to communicate within a neighborhood and while on group outings and has a communications range of less than one mile.

Licensing:

License documents are neither needed nor issued. You are provided authority to operate a FRS unit in places where the FCC regulates radio communications as long as you use only an unmodified FCC certified FRS unit. An FCC certified FRS unit has an identifying label placed on it by the manufacturer. There is no age or citizenship requirement.

Operations:

You may operate your FRS unit within the territorial limits of the fifty United States, the District of Columbia, and the Caribbean and Pacific Insular areas ("U.S."). You may also operate your FRS unit on or over any other area of the world, except within the territorial limits of areas where radio- communications are regulated by another agency of the U.S. or within the territorial limits of any foreign government.

FRS/GMRS Dual Service Radios:

FRS radios must use only permanently-attached antennas. This limitation intentionally restricts the range of communications, and promotes sharing of the available channels.

Some manufacturers have received approval to market radios that are certified for use in both the Family Radio Service (FRS) and the General Mobile Radio Service (GMRS). Other manufacturers have received approval of their radios under the GMRS rules, but market them as FRS/GMRS radios on the basis that:

Some channels are authorized to both services, or

A user of the radio may communicate with stations in the other service.

Radios marketed as "FRS/GMRS" or "dual-service radios" are available from many manufacturers and many retail or discount stores. The manual that comes with the radio, or the label placed on it by the manufacturer, should indicate the service the unit is certified for.

If you operate a radio that has been approved exclusively under the rules that apply to FRS, you are not required to have a license. FRS radios have a maximum power of ½ watt (500 milliwatt) effective radiated power and integral (non-detachable) antennas. If you operate a radio under the rules that apply to GMRS, you must have a GMRS license. GMRS radios generally transmit at higher power levels (1 to 5 watts is typical) and may have detachable antennas.

無線電之聲，對講機電池如何保養？

對講機的原裝電池是廠家經過無數次的精心設計和製造的，目的是為您的對講機提供最佳的性能。以下是深圳即時通科技有限公司總結的一些對講機電池保養經驗可以幫助您避免錯誤的方法使用可充電池，同時增強對講機電池的性能並延長對講機電池的使用壽命。

溫馨提示一：.對講機新的電池在使用前請一定先充電一夜。這種被稱謂「初始化」的方法可以保證電池達到最大的儲電量。

1）鎳鉻電池（NickelCadmium)或鎳氫電池（NickeMetalHydride)首次充電14-16小時。

2）鋰離子電池和鋰聚合物電池（Lithiumlon/polymer):首次充電時指示燈變綠後再多充1-2小時。

溫馨提示二：對講機電池未經過初始化的新電池，請在乾燥通風、溫度涼爽的地方保存。這樣可以避免對講機電池電量和可充電次數的減少。儲存的時間不要超過一下最長時間：

1)鎳鉻電池（NickelCadmium)電池：最長24個月。

2）鎳氫電池（NickeMetalHydride）電池：最長18個月。

3）鋰離子電池和鋰聚合物電池（Lithiumlon/polymer)電池:最長18個月。

溫馨提示三：儲存已經使用過的對講機電池，請先放電50%，並儲存在涼爽、乾燥處。這項提示適用於需要停止使用電池的時間少於30天。

溫馨提示四：每次使用已經停止使用2個月以上的對講機電池，都要先完全放電再完全充電。

1）鎳鉻電池（NickelCadmium)或鎳氫電池（NickeMetalHydride)充電14-16小時。

2）鋰離子電池和鋰聚合物電池（Lithiumlon/polymer):首次充電時指示燈變綠後再多充1-2小時。

溫馨提示五：每次使用快速充電器充電時，在充電指示燈變綠後請在多充1-2小時。

溫馨提示六：每次正常充電完成後，請將對講機電池從充電器中取出，繼續過度充電會縮短對講機電池的使用壽命。因此，不要將充電器當做對講機的底座而使用。

溫馨提示七：只在對講機電池需要充電是進行充電。不要對未完全放電的電池充電，當準備長時間使用對講機時，應攜帶一塊備用電池。這是對需要長時間使用對講機的用戶最有效的解決方案。

溫馨提示八：不要講已經完全充電的對講機電池放入充電器中"額外補充",這樣會使對講機的電池使用壽命嚴重縮短。

溫馨提示九：對講機電池在充電前，先將電池穩定在室溫22度左右。在4度以下或40度以上進行充電，會減短對講機電池的使用壽命。

溫馨提示十：給新的對講機電池充電時，一定要測定進程完成後才能從充電器中取出。對講機充電器指示燈在變成綠色的狀態下才能取出電池。

What is a Network Radio?

Network Radios are a relatively new type of 2-way PTT (Push To Talk) Radio Communications Equipment that make use of existing electronic components, RF modules, touch screens and sub assemblies mass manufactured for the mobile telephone industry. These parts are used to create many styles of handheld, portable and 'in car' devices that feature built in PTT buttons and/or external plug in microphones with a PTT switch.

 Most currently available Network Radios use the Android Operating System allowing easy installation and use of many Android Applications including 2-way simplex communications APPs such as Zello PTT that provides users with easy to operate Global simplex communications. Most network radios can also be used with Bluetooth headsets, speaker mics, headsets, media buttons, keyboards, mice and other peripherals.

 There are growing numbers of unlicensed radio enthusiasts, licensed amateur radio operators and business users making good use of network radio equipment to communicate around the world.

  Although You will hear some people stating that network radios are 'not real radio' or 'not using RF' they are indeed mistaken.

It is correct to state that Network Radios are 'not HAM radios' as they do not operate on frequencies allocated for licensed amateur operation and fall outside the scope of Amateur Radio licensing but they are real radio communications devices that do use RF.

Network radios are effectively classed as 'license exempt radio communications equipment' The end user does not require a license to operate these devices on mobile networks or WiFi connections as the bands of radio spectrum used for mobile network communications are licensed by the network infrastructure owners/network operators and WiFi connections use licence exempt 'ISM band' frequencies.
