Abstract: By research the application of hydraulic support sensors in existing wireless mine pressure monitoring systems, it′s fowd that it always exists unstable data transmission and high sensor power consumption problems. This paper introduces a kind of coal mine hydraulic support pressure sensor based on wireless Mesh ADHoc network, to overcome the problems of unstable data transmission and high sensor power. It takes STM32L412 microcontroller as the core processor, regularly collects pressure data of hydraulic supports, process and stoves the pressure data, and controls the data transferred through the wireless Mesh network to the substation, the pressure data finally reach the ground system. The design combines Mesh module wakeup mechanism with STM32L412 microcontroller lowpower mode to ensure data transmission reliability while also considering the low power consumption of the sensor. After onsite practical application, the hydraulic support pressure sensor has achieved the design goals in terms of network data transmission and low power consumption in the coal mine underground environment, it is suitable for pressure collection and monitoring of hydraulic supports in coal mining face.
Key words : pressure sensor; wireless Mesh; Ad Hoc network; low power consumption

引言

我國(guó)煤礦自上世紀(jì)70年引入綜合機(jī)械化采煤技術(shù)(簡(jiǎn)稱(chēng)“綜采技術(shù)”)[1],,煤礦開(kāi)采效率顯著提高,為經(jīng)濟(jì)的高速發(fā)展提供了充足的能源供應(yīng),,同時(shí)經(jīng)過(guò)各煤礦科研院所,、煤礦企業(yè)單位50余年的不斷探索、創(chuàng)新應(yīng)用,、持續(xù)發(fā)展,,取得一系列矚目的成果,形成針對(duì)不同煤層條件下綜放開(kāi)采技術(shù)與成套裝備,,綜放開(kāi)采技術(shù)已經(jīng)成為我國(guó)開(kāi)采厚煤層的主要方法,,也是我國(guó)在世界煤炭開(kāi)采行業(yè)的標(biāo)志性技術(shù)[2]。綜采的主要裝備包括采煤機(jī),、液壓支架,、端頭支架、刮板輸送機(jī),、轉(zhuǎn)載機(jī),、破碎機(jī)、順槽膠帶輸送機(jī)等,。液壓支架是煤礦開(kāi)采工作中的重要設(shè)備[3],,起到支撐頂板,保護(hù)采煤機(jī),、刮板輸送機(jī)和采煤工作面工人安全作用,。液壓支架由金屬構(gòu)件和若干液壓元件組成,以高壓液體作為動(dòng)力,能實(shí)現(xiàn)支撐,、切頂、自移和推移刮板輸送機(jī)等功能,。液壓支架對(duì)煤礦綜采工作面的安全生產(chǎn)起著至關(guān)重要的作用,是采煤工作面實(shí)現(xiàn)高產(chǎn)高效的關(guān)鍵設(shè)備[4],,通過(guò)監(jiān)測(cè)液壓支架壓力變化規(guī)律分析,得到液壓支架工作初撐力,、末阻力[5],、安全閥開(kāi)啟率、頂板周期來(lái)壓[6],、推進(jìn)度等重要信息,,再對(duì)整個(gè)工作面液壓支架的壓力數(shù)據(jù)進(jìn)行分析,可得出整個(gè)采煤工作面的礦壓顯現(xiàn)規(guī)律,,液壓支架的工作狀態(tài)及礦壓顯現(xiàn)規(guī)律設(shè)定液壓支架的一個(gè)循環(huán)為從液壓支架的初撐力到末阻力的時(shí)間段[7],為煤礦安全提供技術(shù)保障。
