【摘要】：煤炭對(duì)于當(dāng)今中國(guó)社會(huì)來(lái)說(shuō)是重要的生產(chǎn)要素之一,煤機(jī)的自動(dòng)化水平直接關(guān)系著煤礦的生產(chǎn)效率和生產(chǎn)安全。礦用機(jī)械中的掘進(jìn)機(jī)之類的旋轉(zhuǎn)型機(jī)械,在工作過(guò)程中很容易受到煤層的各種撞擊,進(jìn)而會(huì)導(dǎo)致礦用煤機(jī)出現(xiàn)機(jī)械系統(tǒng)的故障,其故障往往表現(xiàn)為異常的振動(dòng)和溫度變化,因此對(duì)于煤機(jī)在工作過(guò)程中的振動(dòng)和溫度狀態(tài)進(jìn)行監(jiān)測(cè)就非常重要了。而傳統(tǒng)的煤機(jī)監(jiān)測(cè)方式一般為有線測(cè)量,但是有線的測(cè)量方式由于跟旋所導(dǎo)致線路纏繞等問(wèn)題不能廣泛實(shí)施,無(wú)線傳感(WSN)技術(shù)能夠有效地解決監(jiān)測(cè)設(shè)備跟旋難題。但是在無(wú)線傳感設(shè)備中基本都是由電池來(lái)負(fù)責(zé)提供能量,電池的電量又給無(wú)線設(shè)備的持續(xù)工作能力帶來(lái)了限制,對(duì)于已經(jīng)安裝到煤機(jī)中的無(wú)線傳感設(shè)備的電池進(jìn)行更換和充電更是成本巨大。因此對(duì)于具有自供電功能的無(wú)線傳感器終端設(shè)備的關(guān)鍵技術(shù)進(jìn)行研究具有很大的現(xiàn)實(shí)意義。本文以研究在線監(jiān)測(cè)采煤機(jī)械工作狀態(tài)的設(shè)備所需關(guān)鍵技術(shù)為目的,在調(diào)研了所需自供電及無(wú)線傳感技術(shù)要求的基礎(chǔ)上,完成了系統(tǒng)樣機(jī)的設(shè)計(jì)。首先,我們針對(duì)發(fā)電器件設(shè)計(jì)了專用的能源管理電路;而后,我們采用Spartan 6 FPGA芯片作為核心控制模塊;采用了數(shù)字式溫度傳感器DS18B20設(shè)計(jì)溫度傳感模塊,在-20℃~80℃范圍內(nèi)的測(cè)量精度可以達(dá)到±0.5℃;基于數(shù)字式加速度傳感器ADXL345設(shè)計(jì)振動(dòng)傳感模塊,其最高采樣率能夠達(dá)到3.2KHz;無(wú)線通信模塊采用藍(lán)牙芯片CC2540完成低功耗、小范圍的傳感數(shù)據(jù)傳輸。通過(guò)動(dòng)態(tài)功耗管理技術(shù)完成系統(tǒng)運(yùn)行邏輯的設(shè)計(jì),基于ISE平臺(tái)完成程序編寫和調(diào)試。最后通過(guò)一系列的實(shí)驗(yàn)驗(yàn)證了系統(tǒng)方案中所設(shè)計(jì)的功能,整體功耗不足一百毫瓦,能夠保障20米范圍的有效數(shù)據(jù)傳輸距離,基本實(shí)現(xiàn)了預(yù)期的設(shè)計(jì)目標(biāo)。
[Abstract]:Coal is one of the important factors of production in today's Chinese society. The automation level of coal machine is directly related to the production efficiency and production safety of the coal mine. The rotary machine such as the driving machine in the mining machinery is easily impacted by various kinds of coal seam impact in the working process, which will lead to the mechanical system of coal mining machine. Fault, the fault often shows abnormal vibration and temperature change, so it is very important to monitor the vibration and temperature state of the coal machine during the working process. And the traditional coal machine monitoring mode is usually wired, but the cable measurement method can not be widely carried out because of the winding caused by the winding. Sensing (WSN) technology can effectively solve the problem of monitoring equipment heel. But in the wireless sensor equipment, the battery is basically responsible for providing energy. The battery's power is also limited to the continuous working capacity of the wireless device. It is more cost to replace and charge the battery for the wireless sensor equipment installed in the coal machine. Therefore, it is of great practical significance to study the key technology of the wireless sensor terminal equipment with self power supply function. This paper aims at the key technology needed to study the equipment for on-line monitoring of the working state of the mining machinery. On the basis of investigating the requirements of the required self power supply and wireless transmission technology, the system sample has been completed. First, we design a special energy management circuit for the power generation device; then we use Spartan 6 FPGA chip as the core control module; the digital temperature sensor DS18B20 is used to design the temperature sensing module, and the measurement precision can reach to 0.5 degrees C in the range of ~80 centigrade at -20 C; based on the digital acceleration transmission. Sensor ADXL345 design vibration sensing module, its maximum sampling rate can reach 3.2KHz; wireless communication module uses Bluetooth chip CC2540 to complete low power, small range sensing data transmission. Through dynamic power management technology to complete system operation logic design, based on the ISE platform completed program writing and debugging. Finally, through a series of real. The function designed in the system scheme is verified. The overall power consumption is less than one hundred milliwatts, and the effective data transmission distance of the 20 meter range can be guaranteed, and the expected design goal is basically realized.
