摘要

本論文使用微處理器單元 (MCU)和RS485，實現可監控各組電壓輸出狀態，不同時間週期開關機測試，AC電源斷電測試，溫度變化狀態並記錄，達成電源供應器燒機室之監控系統。
在這篇論文中，我們系統採用RS485通訊介面，加上Microchip PIC16F887 MCU當作控制處理器，並使用Altium Designer 6設計硬體電路，包含電源供應器的電壓偵測，PG偵測，PS週期時間開關機控制，AC週期時間開關機控制控制，蜂鳴器控制。韌體能支援在線更新功能，使得大批控制板韌體程式重新燒錄更加方便及快速。配合軟體LABVIEW和資料庫所建立的人機介面，讓操作員容易控制與操作，燒機測試狀態也能夠記錄下來供客戶備查。實施電源供應器燒機室之監控系統，可檢驗出不良的產品，進而使品質能夠提升。
此論文的貢獻包含三個部份：
1. 提供長時間全負載的測試環境。可以找出產品的錯誤及生產組裝上的問題。
2. 改善錯誤率及減少客戶送修機率，也可以減少研發和生產成本。
3. 彈性的測試規則設定可以符合戶的需求。使用此系統可以使品質提升，來提供更好的商品給我們的客戶及使用者。

This thesis uses micro controller unit (MCU) and RS485 to implement a monitor system for power supply burn-in room, which has the capability of monitoring the voltage sensor, temperature sensor, turn-on/off cycle test, AC shutdown test.
In this thesis, at first the system is based on RS485 communication interface and MICROCHIP PIC16F887 MCU, using Altium Designer 6 to design the prototype circuit and then using IC LTC1487 output drivers as the controlled for RS485, the design including a power supply output voltage sensor and PG detection, between PS and AC cycle test control. Then, the firmware supports the function of online update, making a large number of control boards to process more conveniently and faster. In addition, combine LABVIEW software and database created for GUI, it provide the operator easier to control and operate, and this test records could be saved and for customers to review. Finally, when the power supply burn-in room test monitor system is implemented, the fails in power supply could be filterable to enhance the product quality.
The contributions of this thesis include three parts:
1. It could find out of wrong components and problems in the mass production.
2. It could reduce the Return Management Application (RMA) to enhance the quality of products; also alleviate R & D and factory manufacture cost.
3. The flexible setting of the test rules could meet customers’ requirements. Therefore, a better quality of merchandise for our customers and users would be achieved.
