臺灣博碩士論文加值系統

本論文採用嵌入式系統中的序列通訊進行傳輸，針對現有販賣設備來改善管理問題1.詢問後台狀態預期補貨狀況2.後台參數修改以防人員設置錯誤3.用韌體更新方法定期維護販賣設備，而研製提出一套販賣設備管理與韌體更新系統，使管理人員能夠即時查閱及更改參數，在同時可管理多部販賣設備。
此系統以UART通訊格式的封包進行傳輸，在販賣設備運作期間，少數管理人員需要即時查詢或更改後臺參數，無法即時地解決每一台販賣設備的問題，也缺少網路集中管理查詢與更改的功能，並在長期執行程式時有產生錯誤狀況，無法得到適當處理。透過此論文提出的販賣設備管理與韌體更新系統，販賣設備能夠迅速得到集中管理，並立即更正錯誤參數，也可以對程式中產生的錯誤，以升級韌體版本方法解決問題。

This paper adopts serial communication in embedded system for transmission, and focuses on the existing vending equipments to improve the management problems: 1. asking the backend status to expect the replenishment status 2. backend parameter modification to prevent the personnel from setting errors 3. using the firmware updating method to maintain the vending equipments regularly, and develops and proposes the management and firmware update system for vending equipments, which enables the management personnel to check and change the parameter in real time, and to manage multiple vending equipments in the same time.
This system uses UART packets for transmission, and during the operation of vending equipment, the managers may need to query or change the parameters of the backend in real time. But they usually cannot solve the problems of each vending equipment in real time, beacuae they lack the function of centralized management of querying and changing equipments over the network, and they may generate errors that cannot be handled appropriately in the long-term implementation of the system. The management and firmware update system for vending equipments proposed in this paper allows centralized management of vending devices and immediate correction of erroneous parameters, as well as upgrading of firmware to address errors in the program.
