【摘要】：木材加工行業(yè)是國(guó)民經(jīng)濟(jì)重要的組成部分，近年來(lái)，隨著人們物質(zhì)生活水平的不斷提高，木材加工行業(yè)得到了快速發(fā)展，而木材干燥技術(shù)作為其關(guān)鍵技術(shù)，，直接影響木制品的質(zhì)量和使用壽命。由于我國(guó)的木材干燥工業(yè)起步比較晚，干燥設(shè)備和技術(shù)距離國(guó)外同行先進(jìn)水平仍有不小差距。本課題的研究目的就是建立一個(gè)木材干燥分布式控制系統(tǒng)，對(duì)木材干燥過(guò)程中溫度、濕度、含水率等關(guān)鍵參數(shù)周期性的進(jìn)行采集，根據(jù)采集到的數(shù)據(jù)，按照一定的木材干燥基準(zhǔn)，通過(guò)對(duì)加熱、噴淋、風(fēng)門(mén)等的控制，對(duì)木材干燥過(guò)程加以相應(yīng)的控制，提高木材干燥的自動(dòng)化程度，提高其生產(chǎn)水平和生產(chǎn)效率，這對(duì)于我國(guó)木材干燥技術(shù)的發(fā)展能起到一定的推動(dòng)作用。最后經(jīng)過(guò)模擬仿真和實(shí)物運(yùn)行調(diào)試，表明系統(tǒng)可以穩(wěn)定可靠的對(duì)木材干燥過(guò)程進(jìn)行有效的控制，基本上達(dá)到了預(yù)定的設(shè)計(jì)目標(biāo)。
[Abstract]:Wood processing industry is an important part of the national economy. In recent years, with the continuous improvement of people's material living standards, the wood processing industry has been developed rapidly, and wood drying technology as its key technology. Directly affect the quality and service life of wood products. Due to the late start of wood drying industry in China, there is still a big gap between drying equipment and technology and the advanced level of foreign counterparts. The purpose of this paper is to establish a distributed control system for wood drying, which collects temperature, humidity, moisture content and other key parameters periodically, according to the collected data. According to a certain wood drying standard, through the control of heating, spray, air door and so on, the wood drying process is controlled accordingly, the automation degree of wood drying is improved, and its production level and production efficiency are improved. This can play a certain role in promoting the development of wood drying technology in China. Finally, through simulation and physical operation and debugging, it is shown that the system can control the wood drying process stably and reliably, and basically achieve the predetermined design objectives.
