摘要: 農(nóng)業(yè)大棚專家在線解答系統(tǒng)是完成農(nóng)業(yè)現(xiàn)代化，解決農(nóng)業(yè)病害問題，全方面促進(jìn)農(nóng)業(yè)健康生長的一個(gè)基本系統(tǒng)。專家可以在農(nóng)業(yè)大棚專家解答系統(tǒng)中為廣大需要解決問題，需要咨詢問題的農(nóng)業(yè)朋友提供全面的解決方案，從大棚技術(shù)，大棚建設(shè)，大棚種植等多方面提供最新，最難，最權(quán)威的專家解答信息。農(nóng)業(yè)大棚專家解答系統(tǒng)，使用最新的網(wǎng)絡(luò)技術(shù)，提供實(shí)時(shí)發(fā)布功能，實(shí)時(shí)通過短信，郵件，在線平臺提供農(nóng)業(yè)大棚問題的解決方案。本文重點(diǎn)研究在linux下架構(gòu)apache服務(wù)器并通過web及數(shù)據(jù)庫完成農(nóng)業(yè)大棚專家在線解答系統(tǒng)。
論文首先分析了農(nóng)業(yè)大棚專家在線解答系統(tǒng)的研究現(xiàn)狀，分析比較了windows下架構(gòu)與Linux下服務(wù)器的不同，并確定選擇了在linux下使用php技術(shù)及mysql技術(shù)完成農(nóng)業(yè)大棚專家在線解答系統(tǒng)。然后使用jquery技術(shù)、ajax技術(shù)、可視化文本CKEditor編輯技術(shù)、phpmailer技術(shù)、XML-SITEMAP技術(shù)等關(guān)鍵技術(shù)進(jìn)行了研究。
論文對農(nóng)業(yè)大棚專家在線解答系統(tǒng)進(jìn)行了總的構(gòu)架概述，明確了設(shè)計(jì)目標(biāo)及設(shè)計(jì)規(guī)則，分析了農(nóng)業(yè)大棚專家在線解答系統(tǒng)需要完成的相關(guān)功能，給出了相關(guān)的技術(shù)方案，詳細(xì)的對農(nóng)業(yè)大棚專家在線解答系統(tǒng)進(jìn)行了技術(shù)開發(fā)及數(shù)據(jù)庫設(shè)計(jì)。
為此本文對于手機(jī)3G網(wǎng)絡(luò)，4G-LTE網(wǎng)絡(luò)對農(nóng)業(yè)大棚專家在線解答系統(tǒng)也進(jìn)行了優(yōu)化，使用了eAccelerator加速機(jī)制，緩存技術(shù)等。同時(shí)論文設(shè)計(jì)了農(nóng)業(yè)大棚專家在線解答系統(tǒng)的功能、登陸功能、郵件收到功能、文本編輯功能、投票功能等完成了信息實(shí)時(shí)與數(shù)據(jù)庫互通，農(nóng)業(yè)專家對農(nóng)民的問題解答，農(nóng)民對專家進(jìn)行提問等功能。

關(guān)鍵詞: 在線解答；農(nóng)業(yè)大棚數(shù)據(jù)庫；實(shí)時(shí)信息

The system of an agicultural expert replying

Abstract:The system of an agricultural expert replying is a basic system which realizes the modernization of agricultural， Solve the problem of agricultural disease， and promote agriculture growth health in all aspects. In this system， experts can help our peasants solve all kinds of agricultural problems and provide comprehensive solutions for them， which are the latest and the most difficult， And the most authoritative. These problems relate to greenhouse technology， construction of greenhouses， greenhouse planting and so on. The system of an agricultural expert replying， using the latest Internet technology ， provides real-time release functions， real time via SMS， email， online platform to provide agricultural greenhouses solution of the problem. It can solve many problems of the vast number of friends at the same time， It also provides the utility function of communicating online production.the system will put all problems together to form a library， for those friends who meet with the same problem， then they do not need to consult experts， They can get the content of the solution directly through the system. Agricultural modernization is the direction of the agricultural development， the system will be a category of the agricultural development products.
First，the paper analyzes the present research situation of The system of an agricultural expert replying， then analysis and compares the different between under Windows and Linux to construct sever. And choose to complete the system under Linux and using PHP and mysql technology. Then using the key technology such as jquery， ajax technology， visual text CKEditor editing techniques， phpmailer technology.
The mobile phone network is gradually popular. We optimized the system， using the start acceleration mechanisms technology， caching technology， etc.， The paper design the function of The system of an agricultural expert replying， the landing， receive emails， text editing functions and vote function to realize the real-time information exchanged with database， agricultural expert problem solving for farmers， farmers to ask experts， and other functions.

Keywords: online answer; Agricultural greenhouses database;real-time information
