Note that after the data communication is started in this way, the confirmation of whether the
因此，流程可終止。通信裝置10可以此方式執行耦合偵測操作M1及耦合偵測操作M2。在耦合偵測操作M2中已偵測到通信裝置10及20透過光纖901及902彼此耦合之後，通信裝置10可開始資料通信操作M3。
Therefore, the flow can be terminated. The
如描述，在通信系統1中，首先，執行使用電信號之耦合偵測操作M1。耦合偵測操作M1涉及偵測通信裝置10及20透過電線911及912彼此耦合。因此，在通信系統1中，當通信裝置10及20未透過傳輸電纜90彼此耦合時，未開始使用光學信號之耦合偵測操作M2。因此，可降低人體曝露於光學信號之可能性。
As described, in the
又，在通信系統1中，可在使用電信號之耦合偵測操作M1之後執行使用光學信號之耦合偵測操作M2。因此，在通信系統1中，可偵測電線911及912連接而光纖901及902斷開之一情況。
Also, in the
再者，可在耦合偵測操作M2中使用脈衝信號，從而導致光學信號之平均能量減小。因此，在光學信號洩漏之一情況中，可抑制洩漏光學信號對人體之影響。 Furthermore, a pulsed signal may be used in the coupling detection operation M2, resulting in a reduction in the average energy of the optical signal. Therefore, in a case where the optical signal leaks, the influence of the leaked optical signal on the human body can be suppressed.
此外，在耦合偵測操作M2中已偵測到光纖901及902之連接之後，可開始使用光學信號之資料通信操作M3。因此，在(例如)光纖901及902斷開之一情況中，未開始使用光學信號之資料通信操作
M3。因此，可降低具有高平均能量之光學信號從光纖901及902洩漏之可能性。
In addition, after the connection of the
另外，在通信系統1中，可提供時間限制Tlim；在使用光學信號之耦合偵測操作M2未在時間限制Tlim內終止之一情況中，可停止傳輸光學信號，且可再次執行使用電信號之耦合偵測操作M1。因此，在通信系統1中，不存在光學信號之不必要連續傳輸。因此，可降低人體曝露於光學信號之可能性。
In addition, in the
再者，在通信系統1中，耦合信號接收器52可連續偵測耦合信號S81。因此，(例如)在傳輸電纜90從通信裝置10及20脫離之一情況中，或在傳輸電纜90斷開之一情況中，可停止傳輸光學信號。因此，可降低人體曝露於光學信號之可能性。
Furthermore, in the
(效應) (effect)
如上文描述，在實施例中，執行使用電信號之耦合偵測操作M1。因此，在通信裝置未透過傳輸電纜彼此耦合之一情況中，未開始使用光學信號之耦合偵測操作M2。因此，可降低人體曝露於光學信號之可能性。 As described above, in the embodiment, the coupling detection operation M1 using the electrical signal is performed. Therefore, in a case where the communication devices are not coupled to each other through the transmission cable, the coupling detection operation M2 using the optical signal is not started. Therefore, the possibility of human exposure to optical signals can be reduced.
在實施例中，可在使用電信號之耦合偵測操作Ml之後執行使用光學信號之耦合偵測操作M2。因此，可偵測電線連接而光纖斷開之一情況。 In an embodiment, the coupling detection operation M2 using the optical signal may be performed after the coupling detection operation M1 using the electrical signal. Therefore, a situation in which the wire is connected and the fiber is disconnected can be detected.
在實施例中，可在耦合偵測操作M2中使用脈衝信號，從而導致光學信號之平均能量減小。因此，在光學信號洩漏之一情況中，可抑制洩漏光學信號對人體之影響。 In an embodiment, a pulsed signal may be used in the coupling detection operation M2, resulting in a reduction in the average energy of the optical signal. Therefore, in a case where the optical signal leaks, the influence of the leaked optical signal on the human body can be suppressed.
在實施例中，可在耦合偵測操作M2之後開始資料通信操作M3。因此，在(例如)光纖斷開之一情況中，未開始使用光學信號之資料通信操作M3。因此，可降低具有高平均能量之光學信號從光纖洩漏之可能性。 In an embodiment, the data communication operation M3 may be started after the coupling detection operation M2. Thus, in the event of a fiber break, for example, the data communication operation M3 using the optical signal is not initiated. Therefore, the possibility of leakage of optical signals with high average energy from the optical fiber can be reduced.
再者，在通信系統1中，可提供一時間限制；在使用光學信號之耦合偵測操作M2未在時間限制內終止之一情況中，可停止傳輸光學信號。因此，不存在光學信號之不必要連續傳輸，從而導致人體曝露於光學信號之可能性降低。
Furthermore, in the
在實施例中，耦合信號接收器可連續偵測耦合信號。因此，(例如)在傳輸電纜從通信裝置脫離之一情況中，或在傳輸電纜斷開之一情況中，可停止傳輸光學信號。因此，可降低人體曝露於光學信號之可能性。 In an embodiment, the coupled signal receiver can continuously detect the coupled signal. Thus, for example, in a situation where the transmission cable is disconnected from the communication device, or in a situation where the transmission cable is disconnected, the transmission of optical signals can be stopped. Therefore, the possibility of human exposure to optical signals can be reduced.
在一個實例中，根據IEC 60825-2中定義之雷射安全性需求應用自動功率減少(APR)。在此，每當連接被判定為斷裂時執行(諸)通信裝置之(諸)傳輸器通道之適當APR。 In one example, automatic power reduction (APR) is applied according to the laser safety requirements defined in IEC 60825-2. Here, an appropriate APR of the transmitter channel(s) of the communication device(s) is performed whenever the connection is determined to be broken.
圖5為繪示一連接建立序列之一實例之一流程圖。可藉由任一或兩個通信裝置(針對該等通信裝置建立一連接)執行該序列。 FIG. 5 is a flow chart illustrating an example of a connection establishment sequence. The sequence may be performed by either or both communication devices for which a connection is established.
在一非連接(NC)狀態(502)中，通信裝置未連接，或至少判定為未連接。一旦製成一連接(504)，則連接建立序列起始，以一電連接建立(ECE)開始，接著一光學連接偵測(OCD)，然後係一建立及組態連接(ECC)。 In a non-connected (NC) state (502), the communication device is not connected, or at least determined not to be connected. Once a connection is made (504), the connection establishment sequence begins, starting with an electrical connection establishment (ECE), followed by an optical connection detection (OCD), and then an establishment and configuration connection (ECC).
使用通信裝置之間的一電連接(諸如先前描述之電線(圖1之911、912))判定ECE(506)。 ECE is determined (506) using an electrical connection between the communication devices, such as the wires previously described (911, 912 of Figure 1).
較佳地，經受連接建立序列之通信裝置將始終觀察且偵測電連接。舉例而言，耦合信號傳輸器透過電連接將一電壓位準提供至另一通信裝置，且耦合信號接收器透過電連接偵測來自另一通信裝置之一電壓位準。控制器經組態以相應地監測該等信號。 Preferably, a communication device undergoing a connection establishment sequence will always observe and detect electrical connections. For example, the coupled signal transmitter provides a voltage level to another communication device through the electrical connection, and the coupled signal receiver detects a voltage level from the other communication device through the electrical connection. The controller is configured to monitor these signals accordingly.
在一個實例中，在缺少一經確認之電連接或「ECE狀態」之情況中，應自通信裝置禁止所有光學輸出。 In one example, in the absence of a confirmed electrical connection or "ECE status", all optical outputs should be disabled from the communication device.
表1提供確認一ECE狀態所滿足之條件之一實例。 Table 1 provides an example of conditions that are met to confirm an ECE status.
一旦建立一ECE狀態，則繼續監測電連接。表2提供以下條件之一實例：當經偵測時導致不再存在一有效ECE狀態或一電連接失效(ECI)之一判定。 Once an ECE state is established, monitoring of the electrical connection continues. Table 2 provides an example of one of the following conditions: when detected, results in a determination that a valid ECE state no longer exists or an electrical connection failure (ECI).
若在任一點處存在一ECI(描繪為ECE「失敗」)，則必須重新建立一ECE以繼續序列。 If there is an ECI at any point (depicted as ECE "failed"), then an ECE must be re-established to continue the sequence.
從例示性持續時間瞭解，一連接階段(ECE)與一斷開階段(ECI)之間存在一時序差。具體而言，ECI中之持續時間短於ECE之持續時間，此促成安全性。又，電纜可係相對長的，故ECE中之臨限值(例如，>2.3V)較佳經配置以考慮從理想電壓之IR降。當在仍較低電壓(例如，<1.0V)處，其可指示電纜將斷裂從而使電阻變得更高之一條件。ECE及ECI之不同時序及臨限值促成安全性。 From the exemplary durations, there is a timing difference between a connect phase (ECE) and a disconnect phase (ECI). Specifically, the duration in ECI is shorter than that in ECE, which contributes to safety. Also, the cables can be relatively long, so the threshold values in the ECE (eg, >2.3V) are preferably configured to account for the IR drop from the ideal voltage. When at still lower voltages (eg, <1.0V), it can indicate a condition where the cable will break, making the resistance higher. Different timing and threshold values for ECE and ECI contribute to safety.
若一ECE經建立且保持為有效，則(該等)通信裝置可執行OCD(508)。OCD較佳涉及經由脈衝光學通信偵測一適當光學連接。 If an ECE is established and remains active, the communication device(s) may perform OCD (508). OCD preferably involves detecting an appropriate optical connection via pulsed optical communication.
圖7為繪示一連接建立序列之電連接偵測(ECE)及光學連接偵測(OCD)部分間的時序關係之一時序圖700。 7 is a timing diagram 700 illustrating the timing relationship between the electrical connection detection (ECE) and optical connection detection (OCD) portions of a connection establishment sequence.
時序圖繪示第一及第二裝置(裝置#1、裝置#2)之連接序列。在時序圖之頂部部分中繪示裝置#1之透視圖。裝置#1功率最初變為H，且此在裝置#2處偵測到，如藉由虛線箭頭指示。類似地，裝置#2功率變為H，且此在裝置#1處ECE期間被偵測到。在一最大值為2秒之有效及
進行中ECE條件內，序列前進至OCD。然而，如在裝置#1部分中指示，可發生一ECI偵測。如在時序圖中指示，此處繪示從H變為L之裝置#1偵測位準。一ECI可為一嚴重劣化電纜、一完全斷開電纜或類似物，且當滿足預定條件(例如，<1.0V)時被偵測到。
The timing diagram shows the connection sequence of the first and second devices (
此時，OCD可已開始(如繪示)，但無論如何，進行中之連接偵測序列在所表示之持續時間(例如，0.5msec)內終止，且序列在ECE處重新開始。首先，裝置#1功率變為L，此在裝置#2處被偵測到。在一時間段後，裝置#1及裝置#2功率兩者同步轉變至H，且正常連接偵測序列繼續，首先進行ECE，接著進行OCD。
At this point, the OCD may have started (as shown), but in any case, the ongoing connection detection sequence terminated within the indicated duration (eg, 0.5 msec), and the sequence restarted at the ECE. First,
OCD(508)中較佳存在四個步驟。通信裝置經組態以針對一有效光學連接之一偵測觀察各種脈衝之脈衝寬度、週期及持續時間。 There are preferably four steps in OCD (508). The communication device is configured to observe pulse widths, periods and durations of various pulses for a detection of an active optical connection.
步驟1： Step 1 :
在第一步驟中，通信裝置之(諸)傳輸通道輸出一第一脈衝信號。圖6A繪示脈衝信號600a之一實例，且下表3列出參數。
In the first step, the transmission channel(s) of the communication device output a first pulse signal. FIG. 6A shows an example of a
步驟1中之脈衝信號相當於先前描述之脈衝信號P11及/或P21。在傳輸側上，一光學傳輸器傳輸脈衝，且在接收側上，一光學接收器接收該等脈衝。通信裝置包含用於執行脈衝信號偵測之電路。如上文描述，此可涉及具有脈衝信號偵測器之一接收器單元，以及經組態以檢查脈衝之時序之一控制器。此OCD功能性可藉由經組態以代表一通信裝置執行脈衝信號偵測之一積體電路執行，其中該積體電路駐留於該通信裝置中。
The pulse signal in
當對於步驟1，通信裝置偵測到具有所定義特性之至少預定數目個連續脈衝時，OCD前進至步驟2。較佳地，具有所定義特性之至少五(5)個連續脈衝之偵測滿足步驟1。但脈衝之特性及脈衝數目可視時序約束等之需求而變化。
When, for
步驟2： Step 2 :
一旦偵測到步驟1之脈衝，則OCD前進至步驟2。步驟2涉及分別具有不同脈衝寬度之兩個脈衝信號。第一脈衝信號具有一第一脈衝寬度且第二脈衝信號具有不同於第一脈衝寬度之一第二脈衝寬度。最初，傳輸第一脈衝信號，接著傳輸第二脈衝信號。儘管該等脈衝信號具有不同脈衝寬度，但OCD之步驟2較佳經配置使得各自脈衝信號之偵測週期之持續時間係相同的。即，若用於偵測第一脈衝信號之持續時間為「T」，則用於偵測第二脈衝信號之持續時間亦為「T」，且用於步驟2之總持續時間為「2T」。
Once the pulse of
圖6B繪示脈衝信號600b之一實例，且下表4列出參數。
FIG. 6B shows an example of the
當對於步驟2之脈衝信號通信裝置偵測到分別具有所定義特性之至少預定數目個連續脈衝時，OCD前進至步驟3。較佳地，根據上文定義之特性，偵測第一脈衝信號之至少五(5)個連續脈衝及接著第二脈衝信號之至少五(5)個連續脈衝滿足步驟2。但同樣地，脈衝之特性及脈衝數目可變化。
When at least a predetermined number of consecutive pulses each having the defined characteristics are detected for the pulse signal communication device of
步驟3： Step 3 :
一旦偵測到步驟2之脈衝，則OCD前進至步驟3。步驟3涉及圖6C及下表5中闡述之具有一脈衝寬度之一脈衝信號。
Once the pulse of
自此等特性瞭解，步驟3之脈衝信號可與來自步驟2之第二脈衝信號(即，較長脈衝寬度)相同。 From these characteristics, the pulse signal of step 3 can be the same as the second pulse signal from step 2 (ie, the longer pulse width).
類似於步驟1，當對於步驟3通信裝置偵測到具有所定義特性之至少預定數目個連續脈衝時，OCD前進至步驟4。較佳地，具有所定義特性之至少五(5)個連續脈衝之偵測滿足步驟3。 Similar to step 1 , when for step 3 the communication device detects at least a predetermined number of consecutive pulses with the defined characteristics, the OCD proceeds to step 4 . Preferably, step 3 is satisfied by the detection of at least five (5) consecutive pulses with the defined characteristics.
步驟4： Step 4 :
若在步驟3中偵測對應裝置(在2msec內)，則系統前進至下一序列(ECC)。 If the corresponding device is detected in step 3 (within 2msec), the system proceeds to the next sequence (ECC).
當在通信裝置中之任何接收通道處偵測到步驟3中定義之任何連續脈衝或未偵測到脈衝時，裝置應停止步驟3信號之脈衝信號從其傳輸通道輸出且完成OCD。 When any continuous pulse as defined in step 3 or no pulse is detected at any receive channel in the communication device, the device shall stop the pulse signal output of step 3 signal from its transmit channel and complete the OCD.
若在一持續時間(例如，3msec)內觀察到任一脈衝且未偵測到任何連續步驟3特性脈衝，則裝置應停止步驟3脈衝之輸出且使其功率接腳小於ECI電壓(例如，<1.0V)達至少150ms，且接著施加大於ECE電壓(例如，>2.3V)以便重新起始ECE。此重新起始可嘗試至多2次。 If any pulse is observed for a duration (eg, 3msec) and no consecutive step 3 characteristic pulses are detected, the device should stop the output of step 3 pulses and keep its power pin less than the ECI voltage (eg, < 1.0V) for at least 150ms, and then apply a voltage greater than ECE (eg, >2.3V) to restart ECE. This restart can be attempted up to 2 times.
偵測連接序列可經配置以使用1msec，故其可花費2msec來執行Tx/Rx電通信。 The detection connection sequence can be configured to use 1 msec, so it can take 2 msec to perform Tx/Rx electrical communication.
一旦OCD結束，則ECC(510)確認用於傳輸/接收之單向通道，分配用於進一步通信之鏈路及配對且適應鏈路時序之一鎖定。一旦ECC 完成，則通信裝置準備進行資料通信。 Once the OCD is over, the ECC (510) confirms the unidirectional channel for transmission/reception, assigns the link and pairing for further communication and accommodates a lock on the timing of the link. Once ECC After completion, the communication device is ready for data communication.
如圖5及圖7中描繪，OCD或ECC之任何失敗可提示ECE處之程序之重新起始。一ECE失敗(ECI)提示如上文描述之ECE程序之重複。 As depicted in Figures 5 and 7, any failure of the OCD or ECC may prompt a restart of the procedure at the ECE. An ECE failure (ECI) indicates a repetition of the ECE procedure as described above.
