Abstract
Description
本發明是有關於一種網路系統，且特別是有關於一種電子電路系統。 The present invention relates to a network system, and particularly relates to an electronic circuit system.
在智能電子系統中，需要對各個終端元件(如電子裝置或電子模組)定義標識符(ID)，以便於對各個終端元件進行管理，亦即自各個終端元件接收資訊或對各個終端元件傳達指令。然而，傳統的標識符由數根微控制器(MCU)的通用輸入/輸出(GPIO)接腳來定義，亦即藉由拉高或拉低微控制器的輸入來定義各個終端元件的終端標識符，此種方式所定義的標識符稱為靜態標識符。 In an intelligent electronic system, it is necessary to define an identifier (ID) for each terminal element (such as an electronic device or electronic module) to facilitate the management of each terminal element, that is, to receive information from each terminal element or communicate to each terminal element instruction. However, the traditional identifier is defined by the general-purpose input/output (GPIO) pins of several microcontrollers (MCU), that is, the terminal identifier of each terminal element is defined by pulling up or pulling down the input of the microcontroller. The identifier defined in this way is called a static identifier.
如果在各個終端元件上依照通用輸入/輸出接腳來定義且印上相對應的標識符，會造成工廠端在生產及管理各個終端元件及進行組裝時會複雜化。並且，如果定義後的終端元件擺放位置出錯，更會對未來各個終端元件進行售後維修時，造成困擾。 If each terminal element is defined in accordance with the universal input/output pins and the corresponding identifier is printed, it will complicate the production, management and assembly of each terminal element on the factory side. In addition, if the position of the defined terminal components is wrong, it will cause troubles during the after-sales maintenance of each terminal component in the future.

The first circuit board has a first controller for providing an initial identifier identification signal. These second circuit boards are connected in series with the first circuit board, and each second circuit board has a second controller and an identifier adjustment block.

FIG. 1 is a system schematic diagram of an electronic circuit system according to an embodiment of the present invention. Please refer to FIG. 1, in this embodiment, the
第一電路板PCB0(亦即電源管理板)具有第一控制器CTL0，用以提供初始標識符識別訊號SID0，其中第一電路板PCB0(亦即第一控制器CTL0)的位置標識符ID固定為0X01。第二電路板PCB1~PCB8個別具有第二控制器CTL1~CTL8、多個電池模組BT1~BT8及多個標識符調整區塊(例如多個標識符調整電路CR1~CR8)，其中第一控制器CTL0及第二控制器CTL1~CTL8會透過匯流排相互耦接。 The first circuit board PCB0 (namely the power management board) has a first controller CTL0 for providing the initial identifier identification signal SID0, wherein the position identifier ID of the first circuit board PCB0 (namely the first controller CTL0) is fixed It is 0X01. The second circuit boards PCB1~PCB8 each have a second controller CTL1~CTL8, a plurality of battery modules BT1~BT8, and a plurality of identifier adjustment blocks (for example, a plurality of identifier adjustment circuits CR1~CR8), of which the first control The controller CTL0 and the second controller CTL1~CTL8 are coupled to each other through the bus.
第二電路板PCB1的標識符調整電路CR1於接收初始標識符識別訊號SID0後調整初始標識符識別訊號SID0的脈波寬度以提供經調整標識符識別訊號SID1，並且第二控制器CTL1接收初始標識符識別訊號SID0以決定第二電路板PCB1的位置標識符 ID(亦即0X02)。第二電路板PCB2的標識符調整電路CR2於接收經調整標識符識別訊號SID1後調整經調整標識符識別訊號SID1的脈波寬度以提供另一經調整標識符識別訊號SID2，並且第二控制器CTL2接收經調整標識符識別訊號SID1以決定第二電路板PCB2的位置標識符ID(亦即0X03)。依據上述，透過不同的脈波寬度的調整標識符識別訊號SID2~SID7，第二控制器CTL3~CTL8個別接收經調整標識符識別訊號SID2~SID7以個別決定第二電路板PCB3~PCB8的位置標識符ID為0X04~0X09。並且，標識符調整電路CR8於接收經調整標識符識別訊號SID7後調整經調整標識符識別訊號SID7的脈波寬度以提供另一經調整標識符識別訊號SID8。 The identifier adjustment circuit CR1 of the second circuit board PCB1 adjusts the pulse width of the initial identifier identification signal SID0 after receiving the initial identifier identification signal SID0 to provide the adjusted identifier identification signal SID1, and the second controller CTL1 receives the initial identification Symbol identification signal SID0 to determine the position identifier of the second circuit board PCB1 ID (ie 0X02). The identifier adjustment circuit CR2 of the second circuit board PCB2 adjusts the pulse width of the adjusted identifier identification signal SID1 after receiving the adjusted identifier identification signal SID1 to provide another adjusted identifier identification signal SID2, and the second controller CTL2 The adjusted identifier identification signal SID1 is received to determine the position identifier ID (ie, 0X03) of the second circuit board PCB2. According to the above, through different pulse width adjustment identifier identification signals SID2~SID7, the second controller CTL3~CTL8 receives the adjusted identifier identification signals SID2~SID7 to individually determine the position identification of the second circuit board PCB3~PCB8 The character ID is 0X04~0X09. Moreover, the identifier adjustment circuit CR8 adjusts the pulse width of the adjusted identifier identification signal SID7 after receiving the adjusted identifier identification signal SID7 to provide another adjusted identifier identification signal SID8.
換言之，第二電路板(如PCB1~PCB8)的標識符調整區塊於接收初始標識符識別訊號SID0或經調整標識符識別訊號(如SID1~SID8)後調整初始標識符識別訊號SID0或經調整標識符識別訊號(如SID1~SID8)的脈波寬度以提供另一經調整標識符識別訊號(如SID1~SID8)，並且各第二電路板(如PCB1~PCB8)的第二控制器(如CTL1~CTL8)接收初始標識符識別訊號SID0或經調整標識符識別訊號(如SID1~SID8)以決定各第二電路板(如PCB1~PCB8)的位置標識符ID。藉此，由於第二電路板(如PCB1~PCB8)是透過不同脈波寬度的標識符識別訊號(如SID0~SID8)且具有同樣的脈寬調整能力的相同電路結構，因此可降低第二電路板的設計及製作成本，並且可提高配置的適應性。 In other words, the identifier adjustment block of the second circuit board (such as PCB1~PCB8) adjusts the initial identifier identification signal SID0 or is adjusted after receiving the initial identifier identification signal SID0 or the adjusted identifier identification signal (such as SID1~SID8) The pulse width of the identifier identification signal (such as SID1~SID8) is used to provide another adjusted identifier identification signal (such as SID1~SID8), and the second controller (such as CTL1) of each second circuit board (such as PCB1~PCB8) ~CTL8) Receive the initial identifier identification signal SID0 or the adjusted identifier identification signal (such as SID1~SID8) to determine the position identifier ID of each second circuit board (such as PCB1~PCB8). As a result, since the second circuit board (such as PCB1~PCB8) uses identifiers with different pulse widths (such as SID0~SID8) to identify signals (such as SID0~SID8) and has the same circuit structure with the same pulse width adjustment capability, the second circuit can be reduced The design and production cost of the board, and can improve the adaptability of the configuration.
在本發明實施例中，第二電路板PCB1~PCB8的第二控制器CTL1~CTL8個別檢測電池模組BT1~BT8，並且個別依據所檢測的結果透過匯流排(例如控制器區域網路(Controller Area Network，CAN)匯流排)回報狀態資訊IST至第一電路板PCB0的第一控制器CTL0，其中狀態資訊IST包含各個第二電路板PCB1~PCB8的位置標識符ID，並且第一電路基於狀態資訊IST中的位置標識符ID判斷狀態資訊IST所對應的第二電路板(如PCB1~PCB8)。並且，第一控制器CTL0可透過各個第二電路板PCB1~PCB8的位置標識符ID對各個第二電路板PCB1~PCB8發送請求或命令。 In the embodiment of the present invention, the second controllers CTL1 to CTL8 of the second circuit boards PCB1 to PCB8 individually detect the battery modules BT1 to BT8, and individually based on the detected results through a bus (such as a controller area network (Controller Area Network) Area Network, CAN) bus) report status information IST to the first controller CTL0 of the first circuit board PCB0, where the status information IST includes the location identifier ID of each second circuit board PCB1~PCB8, and the first circuit is based on the status The location identifier ID in the information IST determines the second circuit board (such as PCB1~PCB8) corresponding to the status information IST. In addition, the first controller CTL0 can send requests or commands to each of the second circuit boards PCB1 to PCB8 through the position identifier ID of each of the second circuit boards PCB1 to PCB8.
在本發明實施例中，第二控制器CTL1~CTL8所傳送的狀態資訊IST包含各個第二電路板PCB1~PCB8的電池模組BT1~BT8的電池電壓、電池溫度及電池電流中的至少其一。 In the embodiment of the present invention, the status information IST transmitted by the second controllers CTL1~CTL8 includes at least one of the battery voltage, battery temperature, and battery current of the battery modules BT1~BT8 of each second circuit board PCB1~PCB8 .
在本發明實施例中，初始標識符識別訊號SID0的脈波寬度為最小脈波寬度，並且第二電路板PCB1~PCB8的標識符調整電路CR1~CR8依時序調大初始標識符識別訊號SID0或經調整標識符識別訊號(如SID1~SID8)的脈波寬度以提供另一經調整標識符識別訊號(如SID1~SID8)。 In the embodiment of the present invention, the pulse width of the initial identifier identification signal SID0 is the minimum pulse width, and the identifier adjustment circuits CR1 to CR8 of the second circuit boards PCB1 to PCB8 increase the initial identifier identification signal SID0 or The pulse width of the identifier identification signal (such as SID1~SID8) is adjusted to provide another adjusted identifier identification signal (such as SID1~SID8).
在本發明另一實施例中，初始標識符識別訊號SID0的脈波寬度為最大脈波寬度，並且第二電路板PCB1~PCB8的標識符調整電路CR1~CR8依時序調小初始標識符識別訊號SID0或經調整標識符識別訊號(如SID1~SID8)的脈波寬度以提供另一經調整 標識符識別訊號(如SID1~SID8)。 In another embodiment of the present invention, the pulse width of the initial identifier identification signal SID0 is the maximum pulse width, and the identifier adjustment circuits CR1 to CR8 of the second circuit boards PCB1 to PCB8 decrease the initial identifier identification signal according to the timing sequence. SID0 or the pulse width of the adjusted identifier identification signal (such as SID1~SID8) to provide another adjusted Identifier identification signal (such as SID1~SID8).
圖2為依據本發明一實施例的第二控制器的標識符判定示意圖。請參照圖1及圖2，在本實施例中，第二控制器CTL1~CTL8內建多個脈波寬度的臨界值Th1~Th9，其定義多個脈波寬度區間。第二控制器CTL1~CTL8基於脈波寬度的臨界值Th1~Th9比較初始標識符識別訊號SID0或經調整標識符識別訊號SID1~SID8的脈波寬度，並且依據比較結果判斷初始標識符識別訊號SID0或經調整標識符識別訊號SID1~SID8所落在的脈波寬度區間，其中初始標識符識別訊號SID0或經調整標識符識別訊號SID1~SID8的脈波寬度會位於不同的脈波寬度區間，因此第二控制器CTL1~CTL8基於不同的脈波寬度區間決定不同的位置標識符ID。 FIG. 2 is a schematic diagram of the identifier determination of the second controller according to an embodiment of the present invention. 1 and 2, in this embodiment, the second controllers CTL1 to CTL8 have built-in multiple thresholds Th1 to Th9 of pulse width, which define multiple pulse width intervals. The second controller CTL1~CTL8 compares the pulse width of the initial identifier identification signal SID0 or the adjusted identifier identification signal SID1~SID8 based on the threshold value Th1~Th9 of the pulse width, and judges the initial identifier identification signal SID0 according to the comparison result Or the pulse width interval where the adjusted identifier identification signals SID1~SID8 fall, where the pulse width of the initial identifier identification signal SID0 or the adjusted identifier identification signals SID1~SID8 will be in different pulse width intervals, so The second controllers CTL1 to CTL8 determine different location identifier IDs based on different pulse width intervals.
舉例來說，假設初始標識符識別訊號SID0及經調整標識符識別訊號SID1~SID8的脈波寬度的工作週期個別約為5%、15%、25%、35%、45%、55%、65%及75%，則脈波寬度臨界值Th1~Th9可以設定為10%、20%、30%、40%、50%、60%、70%、80%及90%的工作週期。透過比較初始標識符識別訊號SID0及經調整標識符識別訊號SID1~SID8的脈波寬度與脈波寬度臨界值Th1~Th9，可以決定出各個第二電路板PCB1~PCB8的位置標識符ID。 For example, suppose that the duty cycles of the pulse widths of the initial identifier identification signal SID0 and the adjusted identifier identification signals SID1~SID8 are respectively about 5%, 15%, 25%, 35%, 45%, 55%, 65 % And 75%, the pulse width threshold Th1~Th9 can be set to 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90% duty cycle. By comparing the pulse width of the initial identifier identification signal SID0 and the adjusted identifier identification signal SID1~SID8 and the pulse width threshold Th1~Th9, the position identifier ID of each second circuit board PCB1~PCB8 can be determined.
再舉例來說，假設初始標識符識別訊號SID0及經調整標識符識別訊號SID1~SID8的脈波寬度的工作週期個別約為95%、85%、75%、65%、55%、45%、35%及25%，則脈波寬度臨界值 Th1~Th9可以設定為90%、80%、70%、60%、50%、40%、30%、20%及10%的工作週期。透過比較初始標識符識別訊號SID0及經調整標識符識別訊號SID1~SID8的脈波寬度與脈波寬度臨界值Th1~Th9，同樣可以決定出各個第二電路板PCB1~PCB8的位置標識符ID。 For another example, suppose that the duty cycles of the pulse widths of the initial identifier identification signal SID0 and the adjusted identifier identification signals SID1~SID8 are respectively about 95%, 85%, 75%, 65%, 55%, 45%, 35% and 25%, the critical value of pulse width Th1~Th9 can be set to 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20% and 10% duty cycle. By comparing the pulse width of the initial identifier identification signal SID0 and the adjusted identifier identification signal SID1~SID8 and the pulse width threshold Th1~Th9, the position identifier ID of each second circuit board PCB1~PCB8 can also be determined.
圖3為依據本發明另一實施例的電子電路系統的系統示意圖。請參照圖1及圖3，電子電路系統200大致相同於電子電路系統100，其不同之處在於第二電路板PCB1a~PCB8a。第二電路板PCB1a~PCB8a的第二控制器CTL1a~CTL8a為個別整合第二控制器CTL1~CTL8及標識符調整電路CR1~CR8的功能，亦即標識符調整電路CR1~CR8的功能是透過第二控制器CTL1a~CTL8a所執行的韌體來實現。

The two controllers individually receive adjusted and individually determined different location identifiers. Thereby, the design and manufacturing cost of the second circuit board can be reduced, and the adaptability of the configuration can be improved.
