The device manager can compose or implement the logical control of a particular device by orchestrating or pulling the control logic instructions 410, 420, 430.

舉例而言,外部設備200_1、200_2~200_N可例如包括冷卻水、冰機、水泵以及水塔。設備管理者可設計監控冷卻水、冰機、水泵以及水塔的監控程序。因此,在圖2中,控制邏輯指令411~415用來表示冷卻水的水溫監控程式。在控制邏輯指令411中,設備管理者可選擇監控冷卻水回水溫。在控制邏輯指令412中,設備管理者可選擇特定運算功能,例如相加或相減。在控制邏輯指令413中,設備管理者可選擇監控冷卻水出水溫。在控制邏輯指令414中,設備管理者可選擇特定條件功能,例如大於或小於。在控制邏輯指令415中,設備管理者可選擇溫度的門檻值為3℃。也就是說,當處理裝置110執行控制邏輯指令410時,嵌入式系統100可監控冷卻水的回水溫與下水溫,並且判斷冷卻水的回水溫與下水溫的溫差是否低於3℃,以進一步決定是否執行控制邏輯指令420、430。For example, the external devices 200_1, 200_2 200 200_N may include, for example, cooling water, an ice machine, a water pump, and a water tower. Equipment managers can design monitoring programs that monitor cooling water, ice machines, pumps, and water towers. Therefore, in Fig. 2, control logic instructions 411 to 415 are used to indicate the water temperature monitoring program of the cooling water. In control logic instruction 411, the equipment manager may choose to monitor the cooling water return water temperature. In control logic instructions 412, the device manager can select specific operational functions, such as addition or subtraction. In control logic instruction 413, the equipment manager may choose to monitor the cooling water outlet temperature. In control logic instructions 414, the device manager can select a particular conditional function, such as greater or lesser. In control logic instruction 415, the device manager can select a temperature threshold of 3 °C. That is, when the processing device 110 executes the control logic instruction 410, the embedded system 100 can monitor the return water temperature and the water temperature of the cooling water, and determine whether the temperature difference between the return water temperature and the water temperature of the cooling water is lower than 3 ° C. To further determine whether to execute control logic instructions 420, 430.

在圖2中,控制邏輯指令421~423用以表示冰機以及水塔的控制程式。當處理裝置110判斷冷卻水的回水溫與下水溫的溫差低於3℃時,處理裝置110執行控制邏輯指令420。在控制邏輯指令421中,設備管理者可選擇控制冰機來冷卻水泵,並且操作冰機以比例微積分(Proportion Integration Differentiation, PID)的調節方式來加載冰機至58赫茲(Hz),以冷卻水泵。在控制邏輯指令422中,設備管理者可設定延遲1000毫秒(ms)的時間。在控制邏輯指令423中,設備管理者可設定以PID的調節方式來加載水塔至58赫茲(Hz)。也就是說,當處理裝置110執行控制邏輯指令420時,處理裝置110可經由連接埠130來輸出控制訊號至冰機以及水塔,以控制冰機以及水塔的負載。In Figure 2, control logic instructions 421-423 are used to represent the control program for the ice machine and the water tower.

在圖2中,控制邏輯指令430包括組合多個控制邏輯指令431~433來表示冰機以及水塔的控制程式。當處理裝置110判斷冷卻水的回水溫與下水溫的溫差未低於3℃時,處理裝置110執行控制邏輯指令430。在控制邏輯指令431中,設備管理者可選擇控制冰機來冷卻水泵,並且操作冰機以比例微積分(Proportion Integration Differentiation, PID)的調節方式來減載冰機至46赫茲(Hz)。在控制邏輯指令432中,設備管理者可設定延遲2500毫秒(ms)的時間。在控制邏輯指令433中,設備管理者可設定以PID的調節方式來減載水塔至46赫茲(Hz)。也就是說,當處理裝置110執行控制邏輯指令430時,處理裝置110可經由連接埠130來輸出控制訊號至冰機以及水塔,以控制冰機以及水塔的負載。In FIG. 2, control logic instructions 430 include control programs that combine a plurality of control logic instructions 431-433 to represent the ice machine and the water tower. When the processing device 110 determines that the temperature difference between the return water temperature of the cooling water and the sewage temperature is not lower than 3 ° C, the processing device 110 executes the control logic command 430. In control logic instruction 431, the equipment manager may choose to control the ice machine to cool the water pump, and operate the ice machine to reduce the load of the ice machine to 46 Hz by a Proportion Integration Differentiation (PID) adjustment. In control logic instruction 432, the device manager can set a time delay of 2500 milliseconds (ms). In control logic instruction 433, the device manager can set the PID to be de-loaded to 46 Hertz (Hz). That is, when the processing device 110 executes the control logic command 430, the processing device 110 can output a control signal to the ice machine and the water tower via the port 130 to control the load of the ice machine and the water tower.

因此,當設備管理者將嵌入式系統100連接至外部設備200_1、200_2~200_N後,設備管理者即可透過視覺化操作控制邏輯模組121來快速地編輯外部設備200_1、200_2~200_N的控制邏輯,而有效控制外部設備200_1、200_2~200_N。也就是說,本實施例的嵌入式系統100可提供便捷的監控系統架設優點。Therefore, after the device manager connects the embedded system 100 to the external devices 200_1, 200_2~200_N, the device manager can quickly edit the control logic of the external devices 200_1, 200_2~200_N through the visual operation control logic module 121.
