【摘要】：實(shí)驗(yàn)室設(shè)備管理是高等學(xué)校管理工作中不可分割的一部分，也是培養(yǎng)學(xué)生工程創(chuàng)新能力的重要途徑。高效的實(shí)驗(yàn)室管理水平可以充分挖掘?qū)嶒?yàn)資源的潛能，提高實(shí)驗(yàn)設(shè)備的使用率和運(yùn)行水平，同時(shí)需要減輕管理人員的勞動(dòng)強(qiáng)度。由于歷史和客觀的原因，現(xiàn)在實(shí)驗(yàn)室出現(xiàn)查詢設(shè)備信息復(fù)雜，設(shè)備信息共享的渠道不暢，資源利用率低等問題。 隨著人類社會(huì)步入信息時(shí)代，物聯(lián)網(wǎng)的概念逐漸被人們認(rèn)識，它將物理基礎(chǔ)設(shè)施和IT基礎(chǔ)設(shè)施整合為統(tǒng)一的基礎(chǔ)設(shè)施，最終形成物物相連的互聯(lián)網(wǎng)。射頻識別(RFID)技術(shù)是物聯(lián)網(wǎng)的關(guān)鍵技術(shù)之一，是以計(jì)算機(jī)和通信技術(shù)為基礎(chǔ)的自動(dòng)識別技術(shù)，可以對每個(gè)物品進(jìn)行標(biāo)識和識別，使得人們可以對大量的數(shù)據(jù)進(jìn)行及時(shí)、準(zhǔn)確的處理。 針對實(shí)驗(yàn)室管理上的現(xiàn)狀，本文結(jié)合物聯(lián)網(wǎng)的思想，設(shè)計(jì)了基于RFID技術(shù)的自動(dòng)控制實(shí)驗(yàn)室設(shè)備管理系統(tǒng)，，用于管理實(shí)驗(yàn)室內(nèi)的四個(gè)實(shí)驗(yàn)系統(tǒng)以及計(jì)算機(jī)等實(shí)驗(yàn)設(shè)備，可增加設(shè)備盤點(diǎn)速度，快捷方便地讀取設(shè)備信息和修改記錄設(shè)備狀態(tài)等，以便減輕管理人員的勞動(dòng)強(qiáng)度，增加實(shí)驗(yàn)室設(shè)備管理的信息化程度和管理效率。 本文從硬件和軟件兩方面完成了以RFID技術(shù)為基礎(chǔ)的自動(dòng)控制實(shí)驗(yàn)室設(shè)備管理系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)。 首先根據(jù)應(yīng)用背景，從系統(tǒng)的功能需求和性能指標(biāo)分析入手，確定了系統(tǒng)頻率，設(shè)計(jì)了讀寫器通信協(xié)議、數(shù)據(jù)編碼方式和后端系統(tǒng)功能，并對常用的防碰撞算法進(jìn)行了分析和選擇，得出系統(tǒng)的總體設(shè)計(jì)方案。而且對貝葉斯估計(jì)算法進(jìn)行了適合實(shí)際使用的改進(jìn)，從橫向和縱向上對貝葉斯算法與其他常用算法進(jìn)行了比較。 然后選擇nRF24L01作為射頻收發(fā)器，完成了讀寫器和電子標(biāo)簽的硬件電路設(shè)計(jì)與調(diào)試。電子標(biāo)簽與設(shè)備一一對應(yīng)，電子標(biāo)簽附在設(shè)備上，存儲(chǔ)設(shè)備的相關(guān)信息。通過讀寫器對電子標(biāo)簽進(jìn)行識別和讀寫操作，實(shí)現(xiàn)對實(shí)驗(yàn)設(shè)備的盤點(diǎn)和對其動(dòng)態(tài)屬性的修改等功能。 在軟件上，在設(shè)計(jì)的讀寫器通信協(xié)議和系統(tǒng)硬件電路基礎(chǔ)上，以狀態(tài)機(jī)的方式實(shí)現(xiàn)了標(biāo)簽的響應(yīng)過程，對讀寫器的各個(gè)功能�？爝M(jìn)行了開發(fā)，并且實(shí)現(xiàn)了讀寫器和電子標(biāo)簽的硬件驅(qū)動(dòng)程序。 根據(jù)設(shè)計(jì)要求，使用Visual C++設(shè)計(jì)了上位機(jī)操作界面，對信息進(jìn)行綜合處理，控制讀寫器工作并操作訪問SQL Server2000數(shù)據(jù)庫，數(shù)據(jù)庫用于存儲(chǔ)設(shè)備的詳細(xì)信息。 最后，對系統(tǒng)的軟硬件進(jìn)行了測試，分析并解決了系統(tǒng)運(yùn)行中出現(xiàn)的問題，基本達(dá)到了系統(tǒng)的設(shè)計(jì)要求。
[Abstract]:Laboratory equipment management is an integral part of university management and an important way to cultivate students' engineering innovation ability. Efficient laboratory management can fully tap the potential of experimental resources, improve the utilization rate and operation level of experimental equipment, and at the same time, reduce the labor intensity of managers. Due to historical and objective reasons, there are some problems in the laboratory, such as the complexity of querying equipment information, the poor channel of equipment information sharing and the low utilization rate of resources. With the human society stepping into the information age, the concept of the Internet of things has been gradually recognized by people. It integrates physical infrastructure and IT infrastructure into a unified infrastructure, and finally forms a connected Internet. Radio frequency identification (RFID) technology is one of the key technologies in the Internet of things. It is an automatic identification technology based on computer and communication technology. Accurate handling. In view of the current situation of laboratory management, this paper designs an automatic control laboratory equipment management system based on RFID technology, which is used to manage four laboratory systems and computer and other experimental equipment, combined with the idea of the Internet of things. It can increase the speed of equipment inventory, read equipment information quickly and conveniently, modify the state of recording equipment and so on, so as to reduce the labor intensity of managers and increase the information level and management efficiency of laboratory equipment management. In this paper, the design and implementation of an automatic control laboratory equipment management system based on RFID technology is completed in both hardware and software. Firstly, according to the application background, the frequency of the system is determined, the communication protocol of reader, the data encoding method and the function of back-end system are designed, based on the analysis of the function requirement and performance index of the system. The common anti-collision algorithm is analyzed and selected, and the overall design scheme of the system is obtained. Moreover, the Bayesian estimation algorithm is improved and compared with other commonly used algorithms both horizontally and longitudinally. Then we select nRF24L01 as RF transceiver to design and debug the hardware circuit of reader and tag. The electronic label corresponds to the device, which is attached to the device and stores information about the device. The electronic tag is recognized and read and written by the reader, and the inventory of the experimental equipment and the modification of its dynamic properties are realized. In software, on the basis of the communication protocol of reader and the hardware circuit of the system, the response process of label is realized by state machine, and the function modules of the reader are developed quickly. And realized the reader and the electronic tag hardware driver. According to the design requirements, the upper computer operation interface is designed with Visual C, the information is processed synthetically, the reader is controlled and the SQL Server 2000 database is operated and accessed. The database is used to store the detailed information of the device. Finally, the software and hardware of the system are tested, and the problems in the system operation are analyzed and solved, and the design requirements of the system are basically achieved.
