礦用本安型瞬變電磁儀

ꄴ上一個(gè)：瞬變電磁儀

ꄲ下一個(gè)： CHB-2000型放炮網(wǎng)絡(luò)全電阻測(cè)試儀

礦用本安型瞬變電磁儀是結(jié)合數(shù)年瞬變電磁法勘探研究，在地面勘探瞬變電磁儀向礦井新型瞬變電磁儀轉(zhuǎn)型，主要用于煤礦掘進(jìn)頭前方及巷道側(cè)幫、煤層頂、底板和工作面內(nèi)富水區(qū)域的探測(cè)。嵌入式操作平臺(tái)、 10.4 寸真彩液晶屏,微弱信號(hào)采集，小功率激勵(lì)電流。儀器屬于本質(zhì)安全型防爆產(chǎn)品，可適合用于有瓦斯、煤塵的礦井環(huán)境。

本產(chǎn)品集發(fā)射接收功能于一體，主要特點(diǎn)如下：

●嵌入式主機(jī)：采用高性能、高主頻、低功耗，配套 10.4 寸真彩液晶顯示屏，形成了智能化、簡(jiǎn)單易用的人機(jī)界面。

●高速數(shù)字信號(hào)處理：采用高速 DSP 作為數(shù)據(jù)采集和預(yù)處理單元，實(shí)現(xiàn)了基于硬件的數(shù)字運(yùn)算邏輯，高效高速的對(duì)采集到的微弱信號(hào)進(jìn)行處理。

●激勵(lì)電路：采用最新高技術(shù)的電子器件，合理設(shè)計(jì)了驅(qū)動(dòng)電路，確保了小功率下電流的高效、關(guān)斷時(shí)間更短。

●自動(dòng)采集系統(tǒng)：按照實(shí)際需求建立好新工程后，只需按“采集”按鈕，就可以完成當(dāng)前點(diǎn)的采集工作。下一次啟動(dòng)銜接上一次采集。儀器還有自動(dòng)增加點(diǎn)號(hào)、線號(hào)功能。

●多種方式數(shù)據(jù)顯示：在采集過(guò)程中可以實(shí)時(shí)顯示當(dāng)前點(diǎn)的數(shù)據(jù)，經(jīng)疊加后的一次場(chǎng)電流波形，二次場(chǎng)的感應(yīng)電壓波形，實(shí)時(shí)觀察數(shù)據(jù)采集情況。在當(dāng)前采集完成后，可以查看每條測(cè)線、每個(gè)測(cè)點(diǎn)、每次觀測(cè)的一次場(chǎng)電流、二次場(chǎng)感應(yīng)電壓、歸一化電位差的任意有效時(shí)間段的波形，并且可以對(duì)歸一化電位差分別進(jìn)行時(shí)間軸對(duì)數(shù)化、電位差軸對(duì)數(shù)化的顯示。

●人工噪聲數(shù)據(jù)排除：當(dāng)用戶在查看數(shù)據(jù)時(shí)，若發(fā)現(xiàn)有明顯的噪聲數(shù)據(jù)，可以選擇該數(shù)據(jù)名稱，然后按 Delete 鍵，將噪聲數(shù)據(jù)刪除。刪除其對(duì)疊加的數(shù)據(jù)的影響。

●安全防爆：內(nèi)置有 7.2V 鎳氫電池電源，外殼采用全密封結(jié)構(gòu)，是屬于本質(zhì)安全型的防爆設(shè)備。

●防潮防塵：儀器殼體使用整體密封的防靜電材料，面板接插件具有防潮防塵功能，在整機(jī)組裝時(shí)采用硅橡膠密封為一整體，外殼防護(hù)等級(jí)達(dá)到 IP54，允許在有瓦斯、煤塵的礦井中使用。
