資料科學家都跟你說：「把資料傳上來，我們就能幫你鍊成黃金!」? 但是當你在身處工廠中，看著加工的機械、奮力工作的工人們時，是否想到一個根本的問題? 資料到底要怎麼得到呢? 為何參加很多雲端應用的研討會都只教你怎麼「處理資料」、「分析資料」，但是就是不跟你說怎麼「得到資料」。 本演講將說明建立一個工廠監控系統時，您如何使用Python語言和冷冰冰的機器對話，藉由工業通訊協定、Sensor來完成工廠資訊的收集。 8 | 9 | ## 大網： 10 | 11 | - 工廠監控 12 | - 工業4.0 13 | - Modbus 14 | - Modbus套件 15 | - PLC 16 | - Power Meter 17 | - MQTT 18 | - Web API
