摘要: | 隨著人類對自然環境的大量開發與利用,有越來越多異常的氣候變化發生,其中微氣候是最容易受到環境變化所影響,同時它也是直接控制著生態系統變化的來源之一。本文即是針對微氣候的變化情形,運用GSM-SMS無線通信機制與GPS定位技術,結合機電整合以及網際網路,研製出一套自動化微氣候觀測系統,有效的取代傳統以人力為主的量測方式。系統包含遠端平台與主控平台兩大部分,遠端平台以低功率16 bit RISC微處理器MSP430F449為其核心,用以整合資料與控制其他模組,收集包括溫度、溼度、風速等環境參數,並預留有其他擴充埠,可供將來其他感測模組連接之用。主控平台為接收、管理、儲存與展現遠端平台所回傳的資料。主控平台以LabVIEW 7.0作為GUI開發工具,結合GSM模組形成簡訊接收程式,用來接收所回傳之資料,並存入MySQL資料庫中,藉由Apache與PHP所建構的即時動態網頁,提供使用者能在任何地方皆可經由網路瀏覽得知遠端最新的微氣候資料。經戶外實測,遠端平台能在開放的環境下穩定操作,簡訊傳送時間平均花費26.5秒,GPS平均誤差距離9.64公尺,並可在不同換環境之下精確的量測其微氣候的差異。 With a large amount of development and utilization of natural environment by the mankind, there are more and more unusual climatic changes. Microclimate among them is most easily influenced by the environmental change. Besides, microclimate is also one of the sources controlling of ecosystem’s change. This research integrates GSM-SMS wireless communication mechanism, Global Positioning System (GPS), mechatronic technique, and internet to establish an automatic microclimate monitoring system. It is effective to replace the traditional method. The system is composed of a remote platform and a host control platform. A low power 16 bit RISC microcontroller MSP430F449 is adopted as core processor of the remote platform. MSP430F449 is utilized to integrate data, control other modules, and collect environmental parameters such as temperature, humidity, wind speed, etc. Moreover, some expansion ports are preserved for other sensors. The host control platform is responsible to receive, manage, store, and show the data from remote platform. LabVIEW 7.0 is adopted as a development tool for User Graphical Interface (GUI) of the host control platform, and integrated with GSM module to develop the SMS receiving program. SMS receiving program takes charge of receiving data and storing data in the MySQL database. The dynamic webpage is established by Apache and PHP. Dynamic webpage can show the latest and past microclimate data to user by internet in any place. According to the field test done outdoors, the remote platform can work steady on the environment of outside. The mean of SMS transmitting time is 26.5 s. The mean of GPS distance error is 9.64 m. The proposed system can accurately measure the different of microclimate. |
