為讓本發明之上述內容能更明顯易懂,下文特舉較佳實施例,並配合所附圖式,作詳細說明如下:In order to make the above-mentioned contents of the present invention more comprehensible, the preferred embodiments are described below, and the detailed description is as follows:
請參照第1圖,其繪示依照本發明第一實施例之多電腦切換系統(Keyboard-Video-Mouse Switch,KVM Switch)100之示意圖,多電腦切換系統100用以透過至少一電腦操作台(Console)CS操作數台電腦PC1~PCN。電腦操作台CS包括一鍵盤、一螢幕及一滑鼠。多電腦切換系統100包括一切換單元110、一控制單元120及至少一感測單元130。在本實施例中係以數個電腦PC1~PCN、一個電腦操作台CS及一個感測單元130為例作說明。切換單元110與電腦操作台CS及數台電腦PC1~PCN相連接,用以切換電腦操作台CS與數台電腦PC1~PCN之間之資料流,使電腦操作台CS得以控制數台電腦PC1~PCN之一。控制單元120與切換單元110連接,用以控制切換單元110。舉例來說,當切換單元110切換電腦操作台CS與其中之一電腦PC2形成通訊時,使用者即可藉由電腦操作台CS操作此台電腦PC2。其中操作之動作包含輸入資料及輸出資料。Referring to FIG. 1 , a schematic diagram of a Keyboard-Video-Mouse Switch (KVM Switch) 100 according to a first embodiment of the present invention is shown. The multi-computer switching system 100 is configured to transmit at least one computer console ( Console) CS operates several computers PC1~PCN. The computer console CS includes a keyboard, a screen and a mouse. The KVM switching system 100 includes a switching unit 110, a control unit 120, and at least one sensing unit 130. In this embodiment, a plurality of computers PC1~PCN, a computer console CS and a sensing unit 130 are taken as an example for description. The switching unit 110 is connected to the computer console CS and the plurality of computers PC1~PCN for switching the data flow between the computer console CS and the plurality of computers PC1~PCN, so that the computer console CS can control several computers PC1~ One of the PCN. The control unit 120 is connected to the switching unit 110 for controlling the switching unit 110. For example, when the switching unit 110 switches the computer console CS to form communication with one of the computers PC2, the user can operate the computer PC2 by the computer console CS. The action of the operation includes input data and output data.
感測單元130與控制單元120形成通訊,用以感測一預定範圍之內是否存在一物體,並據以輸出一感測訊號S10。其中,控制單元120根據感測訊號S10控制切換單元110,於電腦操作台CS登入或登出一管理介面。管理介面係由多電腦切換系統100所提供。當使用者登入管理介面後,始可操作多電腦切換系統100。當使用者登出管理介面時,則無法操作多電腦切換系統100。一般而言,使用者在登入管理介面時,需要輸入帳號名稱及帳號密碼;使用者在登出管理介面時,則需要觸發一登出選項。The sensing unit 130 forms a communication with the control unit 120 to sense whether an object exists within a predetermined range, and accordingly outputs a sensing signal S10. The control unit 120 controls the switching unit 110 according to the sensing signal S10, and logs in or logs out of a management interface on the computer console CS. The management interface is provided by the KVM switching system 100. The multi-computer switching system 100 can be operated after the user logs in to the management interface. When the user logs out of the management interface, the KVM switching system 100 cannot be operated. In general, when logging in to the management interface, the user needs to enter the account name and account password. When the user logs out of the management interface, the user needs to trigger a logout option.
請參照第2圖,其繪示依照本發明第一實施例之多電腦切換系統100之控制流程圖。首先,在步驟0102中,以感測單元130感測預定範圍之內是否存在物體,並據以輸出感測訊號S。Please refer to FIG. 2, which shows a control flow chart of the KVM switching system 100 according to the first embodiment of the present invention. First, in step 0102, the sensing unit 130 senses whether an object exists within a predetermined range, and accordingly outputs a sensing signal S.
接著,在步驟0104中,控制單元120接收感測訊號S10,並判斷感測訊號S10之內容代表「預定範圍存在物體」之狀態或「預定範圍不存在物體」之狀態。若感測訊號S10代表「預定範圍內存在物體」之狀態,則進入步驟0106;若感測訊號S10代表「預定範圍內不存在物體」之狀態,則進入步驟0108。Next, in step 0104, the control unit 120 receives the sensing signal S10, and determines that the content of the sensing signal S10 represents the state of "predetermined range existing object" or the state of "predetermined range non-existing object". If the sensing signal S10 represents the state of "the object exists within the predetermined range", the process proceeds to step 0106; if the sensing signal S10 represents the state of "the object does not exist within the predetermined range", the process proceeds to step 0108.
在步驟0106中,控制單元120控制切換單元110,於電腦操作台CS登入管理介面。In step 0106, the control unit 120 controls the switching unit 110 to log in to the management interface at the computer console CS.
在步驟0108中,控制單元120控制切換單元110,於電腦操作台CS登出管理介面。In step 0108, the control unit 120 controls the switching unit 110 to log out of the management interface at the computer console CS.
其中,電腦操作台CS與多電腦切換系統100係可整合於同一機台內,例如是LCD KVM。電腦操作台CS與多電腦切換系統100亦可分別獨立設置。感測單元130係可設置於使用者在操作電腦操作台CS時可能的活動範圍。例如感測單元130可直接安裝於電腦操作台CS之螢幕上,或者感測單元130亦可設置於電腦操作台CS之螢幕的附近,以感測在預定範圍內是否存在使用者。如此,即可得知使用者是否離開電腦操作台CS。The computer console CS and the multi-computer switching system 100 can be integrated in the same machine, such as an LCD KVM. The computer console CS and the multi-computer switching system 100 can also be independently set. The sensing unit 130 can be disposed in a range of possible activities when the user operates the computer console CS. For example, the sensing unit 130 can be directly mounted on the screen of the computer console CS, or the sensing unit 130 can also be disposed in the vicinity of the screen of the computer console CS to sense whether there is a user within a predetermined range. In this way, it is known whether the user leaves the computer console CS.
感測單元130之感測訊號S10係可以無線傳輸方式或有線傳輸方式傳遞至控制單元120。在本實施例中,感測單元130與控制單元120係以有線傳輸方式連接。如第1圖所示,感測單元130進一步包括一第一連接埠131。控制單元120進一步包括一第二連接埠121。第一連接埠131及第二連接埠121係以一傳輸線L連接,感測訊號S10係經由第一連接埠131、傳輸線L及第二連接埠121傳遞至控制單元120。The sensing signal S10 of the sensing unit 130 can be transmitted to the control unit 120 in a wireless transmission manner or a wired transmission manner. In this embodiment, the sensing unit 130 and the control unit 120 are connected in a wired transmission manner. As shown in FIG. 1 , the sensing unit 130 further includes a first connection port 131 . The control unit 120 further includes a second port 121. The first port 131 and the second port 121 are connected by a transmission line L, and the sensing signal S10 is transmitted to the control unit 120 via the first port 131, the transmission line L and the second port 121.
當使用者走近感測單元130之預定範圍時,控制單元120透過感測訊號S10之內容即可得知使用者走近了電腦操作台CS之螢幕,並隨即控制切換單元110,於電腦操作台CS自動地登入管理介面。如此一來,使用者不需特地輸入帳號名稱及帳號密碼,即可在走近電腦操作台CS的同時,立即登入管理介面。反之,當使用者離開感測單元130之預定範圍時,控制單元120透過感測訊號S10之內容即可得知使用者離開了電腦操作台CS之螢幕,並隨即控制切換單元110,於電腦操作台CS自動地登出管理介面。如此一來,使用者不需特地點選某一登出選項,即可在離開電腦操作台CS時,立即自動地登出管理介面。When the user approaches the predetermined range of the sensing unit 130, the control unit 120 can know that the user approaches the screen of the computer console CS through the content of the sensing signal S10, and then controls the switching unit 110 to operate the computer. The station CS automatically logs into the management interface. In this way, the user can log in to the management interface immediately after approaching the computer console CS without having to specifically enter the account name and account password. On the other hand, when the user leaves the predetermined range of the sensing unit 130, the control unit 120 can know that the user has left the screen of the computer console CS through the content of the sensing signal S10, and then controls the switching unit 110 to operate the computer. The station CS automatically logs out of the management interface. In this way, the user can automatically log out of the management interface immediately when leaving the computer console CS without having to select a certain logout option.
另外,在某些安全度要求較高的多電腦切換系統100中,控制單元120的控制方式具又較高地安全度考量。例如在感測訊號S10代表預定範圍之內存在物體之狀態下,控制單元120仍於電腦操作台CS要求使用者輸入帳號名稱及帳號密碼。而僅在感測訊號S10代表預定範圍之內不存在物體之狀態下,控制單元120於電腦操作台CS自動地登出管理介面。In addition, in some of the KVM switching systems 100 where the security requirements are high, the control mode of the control unit 120 has a high degree of security considerations. For example, in a state where the sensing signal S10 represents an object within a predetermined range, the control unit 120 still asks the user to input an account name and an account password at the computer console CS. The control unit 120 automatically logs out of the management interface on the computer console CS only in a state where the sensing signal S10 represents that there is no object within the predetermined range.
請參照第3圖,其繪示依照本發明第二實施例之多電腦切換系統200之示意圖。本實施例之多電腦切換系統200與第一實施例之多電腦切換系統100不同之處在於:感測單元230與控制單元220係以一無線傳輸方式連接,其餘相同之處不再重述。Please refer to FIG. 3, which illustrates a schematic diagram of a multi-computer switching system 200 in accordance with a second embodiment of the present invention. The multi-computer switching system 200 of the present embodiment is different from the multi-computer switching system 100 of the first embodiment in that the sensing unit 230 and the control unit 220 are connected in a wireless transmission manner, and the rest are not repeated.
如第3圖所示,感測單元230進一步包括一第一無線傳輸模組231,控制單元220進一步包括一第二無線傳輸模組221,感測訊號S20係經由第一無線傳輸模組231及第二無線傳輸模組221傳遞至控制單元220。當電腦操作台CS與控制單元220距離遙遠時,透過無線傳輸方式連接感測單元230與控制單元220可省去了冗長且雜亂的傳輸線。或者感測單元230亦可依據使用者之活動範圍設置於牆壁或桌面,相當地方便。As shown in FIG. 3, the sensing unit 230 further includes a first wireless transmission module 231. The control unit 220 further includes a second wireless transmission module 221, and the sensing signal S20 is transmitted through the first wireless transmission module 231. The second wireless transmission module 221 is delivered to the control unit 220. When the computer console CS and the control unit 220 are far away, connecting the sensing unit 230 and the control unit 220 by wireless transmission can save a long and messy transmission line. Alternatively, the sensing unit 230 can be disposed on a wall or a desktop according to the range of motion of the user, which is quite convenient.
請參照第4圖,其繪示依照本發明第三實施例之多電腦切換系統300之示意圖。本實施例之多電腦切換系統300與第一實施例之多電腦切換系統100不同之處在於:本實施例之多電腦切換系統300進一步包括一計時單元340,其餘相同之處不再重述。Please refer to FIG. 4, which is a schematic diagram of a multi-computer switching system 300 according to a third embodiment of the present invention. The multi-computer switching system 300 of the present embodiment is different from the multi-computer switching system 100 of the first embodiment in that the multi-computer switching system 300 of the present embodiment further includes a timing unit 340, and the rest of the same is not repeated.
計時單元340與控制單元120形成通訊,用以計算感測訊號S10持續為同一狀態之一累計時間T。其中控制單元120進一步根據累計時間T控制切換單元110,於電腦操作台CS登入或登出管理介面。The timing unit 340 forms a communication with the control unit 120 for calculating the accumulated time T of the sensing signal S10 being one of the same states. The control unit 120 further controls the switching unit 110 according to the accumulated time T, and logs in or logs out of the management interface at the computer console CS.
請參照第5圖,其繪示依照本發明第三實施例之多電腦切換系統300之控制流程圖。首先,在步驟0302中,以感測單元130感測預定範圍之內是否存在物體,並據以輸出感測訊號S10,其中該感測訊號S10具有代表「預定範圍存在物體」之第一狀態及代表「預定範圍不存在物體」之第二狀態。Referring to FIG. 5, a control flow chart of the KVM switching system 300 according to the third embodiment of the present invention is shown. First, in step 0302, the sensing unit 130 senses whether an object exists within a predetermined range, and accordingly outputs a sensing signal S10, wherein the sensing signal S10 has a first state representing a "predetermined range of existing objects" and Represents the second state of "the object does not exist in the predetermined range."
接著,在步驟0304中,計時單元340計算感測訊號S10持續為同一狀態之累計時間T,且當該感測訊號S10之狀態改變時,歸零該累計時間T。Next, in step 0304, the timing unit 340 calculates the cumulative time T that the sensing signal S10 continues to be in the same state, and when the state of the sensing signal S10 changes, the accumulated time T is zeroed.
然後,在步驟0306中,控制單元120判斷累計時間T是否大於預定時間(例如是5秒鐘)。若累計時間T大於預定時間,則執行步驟0308;若累計時間T不大於預定時間,則回至步驟0302。Then, in step 0306, the control unit 120 determines whether the accumulated time T is greater than a predetermined time (for example, 5 seconds). If the accumulated time T is greater than the predetermined time, step 0308 is performed; if the accumulated time T is not greater than the predetermined time, then return to step 0302.
在步驟0308中,控制單元120判斷感測訊號S10之內容代表「預定範圍存在物體」之狀態或「預定範圍不存在物體」之狀態。若感測訊號S10代表「預定範圍內存在物體」之狀態,則進入步驟0310;若感測訊號S10代表「預定範圍內不存在物體」之狀態,則進入步驟0312。In step 0308, the control unit 120 determines that the content of the sensing signal S10 represents the state of the "predetermined range existing object" or the state of "predetermined range non-existing object". If the sensing signal S10 represents the state of "the object exists within the predetermined range", the process proceeds to step 0310; if the sensing signal S10 represents the state of "the object does not exist within the predetermined range", the process proceeds to step 0312.
在步驟0310中,控制單元120控制切換單元110,於電腦操作台CS登入管理介面。In step 0310, the control unit 120 controls the switching unit 110 to log in to the management interface at the computer console CS.
在步驟0312中,控制單元120控制切換單元110,於電腦操作台CS登出管理介面。In step 0312, the control unit 120 controls the switching unit 110 to log out of the management interface at the computer console CS.
請參照第6圖,其繪示感測訊號S10之狀態的時序表及管理介面登入或登出之狀態的時序表。在本實施例中,預定時間係以5秒為例。在第4-5秒之間,感測訊號S10代表預定範圍內不存在物體之狀態,但其累計時間T僅有1秒鐘。因此,第4-5秒之間表示可能只是使用者不小心偏離了預定範圍,並非使用者離開電腦操作台CS。於是,控制單元120並未在第5秒執行登出之動作。Please refer to FIG. 6 , which shows a timing chart of the state of the sensing signal S10 and a timing chart of the state of the login or logout of the management interface. In the present embodiment, the predetermined time is exemplified by 5 seconds. Between the 4th and 5th seconds, the sensing signal S10 represents the state in which no object exists within the predetermined range, but the accumulated time T is only 1 second. Therefore, the indication between the 4th and 5th seconds may be that the user accidentally deviates from the predetermined range, and the user does not leave the computer console CS. Thus, the control unit 120 does not perform the logout action in the 5th second.
在第17-40秒之間,感測訊號S10代表預定範圍內不存在物體之狀態,其累計時間T在第22秒時已超過預定時間(5秒)。因此,第17-22秒之間表示使用者的確離開了電腦操作台CS。於是,控制單元120在第22秒之後執行登出之動作。Between the 17th and 40th seconds, the sensing signal S10 represents a state in which no object exists within a predetermined range, and the accumulated time T has exceeded the predetermined time (5 seconds) at the 22nd second. Therefore, between 17 and 22 seconds, the user does leave the computer console CS. Thus, the control unit 120 performs the logout action after the 22nd second.
在第40-42秒之間,感測訊號S10代表預定範圍內存在物體之狀態,但其累計時間T僅有2秒鐘。因此,第40-42秒之間表示可能只是某一物體經過了預定範圍,並非使用者準備操作電腦操作台CS。於是,控制單元120並未在第42秒執行登入之動作。Between the 40th and 42nd second, the sensing signal S10 represents the state of the object within the predetermined range, but the accumulated time T is only 2 seconds. Therefore, between 40 and 42 seconds, it is indicated that only an object has passed the predetermined range, and the user is not ready to operate the computer console CS. Thus, the control unit 120 does not perform the login action at the 42nd second.
在第50-60秒之間,感測訊號S10代表預定範圍內存在物體之狀態,其累計時間T在第55秒時已超過預定時間(5秒)。因此,第50-60秒之間表示使用者的確準備操作電腦操作台CS。於是,控制單元120在第55秒之後執行登入之動作。Between the 50th and 60th second, the sensing signal S10 represents the state of the object within the predetermined range, and the accumulated time T has exceeded the predetermined time (5 seconds) at the 55th second. Therefore, between 50 and 60 seconds means that the user is indeed ready to operate the computer console CS. Thus, the control unit 120 performs the login action after the 55th second.
如此一來,控制單元120透過感測訊號S10及累計時間T兩者之資料,即可更準確地判斷使用者是否確實離開了電腦操作台CS或準備操作電腦操作台CS,而避免了誤判的窘境。In this way, the control unit 120 can more accurately determine whether the user has actually left the computer console CS or is ready to operate the computer console CS by using the data of the sensing signal S10 and the accumulated time T, thereby avoiding misjudgment. Dilemma.
當然在某些安全度要求較高的多電腦切換系統300中,控制單元120具有較高安全度的考量。例如在感測訊號S10代表預定範圍之內存在物體之狀態下,控制單元120仍於電腦操作台CS要求使用者輸入帳號名稱及帳號密碼。而僅在感測訊號S10代表預定範圍之內不存在物體,且累計時間T大於預定時間之狀態下,控制單元120才自動地執行登出之動作。Of course, in some KVM switching systems 300 where the security requirements are high, the control unit 120 has a high security consideration. For example, in a state where the sensing signal S10 represents an object within a predetermined range, the control unit 120 still asks the user to input an account name and an account password at the computer console CS. The control unit 120 automatically performs the logout action only when the sensing signal S10 represents that there is no object within the predetermined range and the accumulated time T is greater than the predetermined time.
請參照第7圖,其繪示依照本發明第四實施例之多電腦切換系統400之示意圖。本實施例之多電腦切換系統400與第一實施例之多電腦切換系統100不同之處在於:本實施例之多電腦切換系統400係以數個電腦PC1~PCN、數個電腦操作台CS1~CSN及數個感測單元430(1)~430(N)為例作說明,其餘相同之處不再重述。Please refer to FIG. 7, which is a schematic diagram of a multi-computer switching system 400 according to a fourth embodiment of the present invention. The multi-computer switching system 400 of the present embodiment is different from the multi-computer switching system 100 of the first embodiment in that the multi-computer switching system 400 of the embodiment is a plurality of computers PC1~PCN and a plurality of computer operating stations CS1~ The CSN and the plurality of sensing units 430(1) to 430(N) are taken as an example for description, and the rest of the similarities are not repeated.

The control unit 120 controls the switching unit 110 to log in or log out of the management interface at the corresponding station CS1~CSN according to the received sensing signals S41~S4N. The control unit 120 processes the received sensing signals S41~S4N separately, and controls the corresponding computer operating stations CS1~CSN respectively. Each computer operating station CS1~CSN can be designed to operate independently without interfering with each other.
請參照第8圖,其繪示依照本發明第五實施例之多電腦切換系統500之示意圖。本實施例之多電腦切換系統500與第一實施例之多電腦切換系統100不同之處在於:本實施例之多電腦切換系統500進一步包括訊號轉換單元550及訊號轉換單元560(1)~560(N),其餘相同之處不再重述。Please refer to FIG. 8 , which is a schematic diagram of a multi-computer switching system 500 according to a fifth embodiment of the present invention. The multi-computer switching system 500 of the present embodiment is different from the multi-computer switching system 100 of the first embodiment in that the multi-computer switching system 500 of the embodiment further includes a signal conversion unit 550 and a signal conversion unit 560(1)-560. (N), the rest of the same points are not repeated.
訊號轉換單元550係與電腦操作台CS、感測單元130、控制單元120及切換單元110電性連接。訊號轉換單元550用以分別轉換電腦操作台CS之訊號C(例如是滑鼠訊號、鍵盤訊號及螢幕訊號)及感測訊號S10為第一差動訊號N1及第二差動訊號N2,並分別傳遞至切換單元110及控制單元120。反之,訊號轉換單元550亦可轉換第一差動訊號N1為電腦操作台CS之訊號C,並傳遞至電腦操作台CS。The signal conversion unit 550 is electrically connected to the computer console CS, the sensing unit 130, the control unit 120, and the switching unit 110. The signal conversion unit 550 is configured to respectively convert the signal C (such as the mouse signal, the keyboard signal and the screen signal) of the computer console CS and the sensing signal S10 into the first differential signal N1 and the second differential signal N2, respectively. Transfer to the switching unit 110 and the control unit 120. On the other hand, the signal conversion unit 550 can also convert the first differential signal N1 to the signal C of the computer console CS and transmit it to the computer console CS.
訊號轉換單元560(1)~560(N)係分別與電腦PC1~PCN及切換單元110電性連接。訊號轉換單元560(1)~560(N)用以轉換電腦PC1~PCN之訊號P1~PN為第三差動訊號N3(1)~N3(N),並傳遞至切換單元110。反之,訊號轉換單元560(1)~560(N)亦可轉換第三差動訊號N3(1)~N3(N)為電腦PC1~PCN之訊號P1~PN,並傳遞至電腦PC1~PCN。The signal conversion units 560(1) to 560(N) are electrically connected to the computers PC1 to PCN and the switching unit 110, respectively. The signal conversion units 560(1) to 560(N) are used to convert the signals P1~PN of the computers PC1~PCN into the third differential signals N3(1)~N3(N), and transmit them to the switching unit 110. On the contrary, the signal conversion units 560(1) to 560(N) can also convert the third differential signals N3(1) to N3(N) to the signals P1~PN of the PC1~PCN and transmit them to the computers PC1~PCN.
因此原本之電腦操作台CS之訊號C(含滑鼠訊號、鍵盤訊號、螢幕訊號)及感測訊號S10需要四條傳輸線進行傳輸,而經由訊號轉換單元550使用訊號混合編碼技術將該等訊號轉換為第一差動訊號N1及第二差動訊號N2,則僅需一條傳輸線即可進行傳輸。不僅減少了線材,更減少了傳輸線之插頭數量,相當地方便使用。Therefore, the signal C of the original computer console CS (including the mouse signal, the keyboard signal, the screen signal) and the sensing signal S10 need four transmission lines for transmission, and the signal conversion unit 550 converts the signals into signals by using the signal mixing coding technology. The first differential signal N1 and the second differential signal N2 are transmitted by only one transmission line. Not only the wire is reduced, but also the number of plugs of the transmission line is reduced, which is quite convenient to use.

The second signal conversion unit 680 is connected to the first signal conversion unit 670, the control unit 120, and the switching unit 110. After receiving the differential signal N, the second signal conversion unit 680 converts the differential signal N into the signal C and the sensing signal S of the computer station CS, and transmits the signal to the switching unit 110 and the control unit 120, respectively. On the contrary, the second signal conversion unit 680 is the differential signal N of the computer console CS outputted by the switchable switching unit 110, and the first signal conversion unit 680 receives the differential signal N and converts the differential signal N into a computer. The signal C of the console CS is transmitted to the computer console CS.
此外,在第二訊號轉換單元680轉換訊號的同時,更放大訊號的強度或針對傳輸路徑之衰減進行補償,以使訊號可傳遞的更遠。In addition, while the second signal conversion unit 680 converts the signal, the intensity of the signal is amplified or compensated for the attenuation of the transmission path, so that the signal can be transmitted further.

The video switching system 1000 is configured to display a plurality of video sources DS1 DSDSN through at least one screen D. The video switching system 1000 includes a switching unit 1010, a control unit 1020, and at least one sensing unit 1030. In this embodiment, the video switching system 1000 is described by taking one screen D, a plurality of video sources DS1 to DSN, and one sensing unit 1030 as an example.

The control unit 1020 is connected to the switching unit 1010. The control unit 1020 is configured to control the switching unit 1010.
感測單元1030與控制單元1020形成通訊。感測單元1030用以感測一預定範圍之內是否存在一物體,並據以輸出一感測訊號S100。其中,控制單元1020根據感測訊號S100控制切換單元1010,於螢幕D顯示視訊源DS1~DSN之一。The sensing unit 1030 forms a communication with the control unit 1020. The sensing unit 1030 is configured to sense whether an object exists within a predetermined range, and accordingly output a sensing signal S100. The control unit 1020 controls the switching unit 1010 according to the sensing signal S100, and displays one of the video sources DS1 DSDSN on the screen D.
請參照第17圖,其繪示依照本發明第十實施例之視訊切換系統1000之控制流程圖。首先,在步驟1002中,以感測單元1030感測預定範圍之內是否存在物體,並據以輸出感測訊號S100。Referring to FIG. 17, a control flow chart of a video switching system 1000 according to a tenth embodiment of the present invention is shown. First, in step 1002, the sensing unit 1030 senses whether an object exists within a predetermined range, and accordingly outputs a sensing signal S100.
接著,在步驟1004中,控制單元1020接收感測訊號S100,並判斷感測訊號S100之內容代表「預定範圍存在物體」之狀態或「預定範圍不存在物體」之狀態。若感測訊號S100代表「預定範圍內存在物體」之狀態,則進入步驟1006;若感測訊號S100代表「預定範圍內不存在物體」之狀態,則進入步驟1008。Next, in step 1004, the control unit 1020 receives the sensing signal S100, and determines that the content of the sensing signal S100 represents the state of "predetermined range existing object" or the state of "predetermined range does not exist object". If the sensing signal S100 represents the state of "the object exists within the predetermined range", the process proceeds to step 1006; if the sensing signal S100 represents the state of "the object does not exist within the predetermined range", the process proceeds to step 1008.
在步驟1006中,控制單元1020控制切換單元1010,於螢幕D顯示一種視訊源(例如是視訊源DS1)。In step 1006, the control unit 1020 controls the switching unit 1010 to display a video source (for example, the video source DS1) on the screen D.
在步驟1008中,控制單元1020控制切換單元1010,於螢幕D顯示另一種視訊源(例如是視訊源DS2)。In step 1008, the control unit 1020 controls the switching unit 1010 to display another video source (for example, the video source DS2) on the screen D.
舉例來說,當本實施例之視訊切換系統1000應用於賣場時,感測單元1030係可設置於賣場入口處。在「預定範圍內不存在物體」之狀態下,控制單元1020控制切換單元1010於螢幕D播放「賣場形象廣告」之訊息。在「預定範圍存在物體」之狀態下,控制單元1020控制切換單元1010於螢幕D播放「歡迎光臨」之訊息。如此一來,螢幕D既可播放「賣場形象廣告」之訊息,在顧客進門時,亦可播放「歡迎光臨」之訊息。For example, when the video switching system 1000 of the embodiment is applied to a store, the sensing unit 1030 can be disposed at the entrance of the store. In a state where "the object does not exist in the predetermined range", the control unit 1020 controls the switching unit 1010 to play the "store image advertisement" message on the screen D. In a state where "the object exists in the predetermined range", the control unit 1020 controls the switching unit 1010 to play the message "Welcome" on the screen D. In this way, the screen D can play the message of "store image advertisement", and the message "Welcome" can also be played when the customer enters the door.

The multi-computer switching system 1100 of the present embodiment is different from the multi-computer switching system 1000 of the tenth embodiment in that the video switching system 1100 of the embodiment is a screen D, a plurality of video sources DS1~DSN, and a plurality of senses. The measuring units 1130(1)~1130(N) are taken as an example for description, and the rest of the similarities are not repeated.
各感測單元1130(1)~1130(N)對應數個視訊源DS1~DSN其中之一。控制單元1020接收其中之一感測單元1130(1)~1130(N)所產生之感測訊號S111~S11N後,控制切換單元1010於螢幕D顯示對應之視訊源DS1~DSN。Each of the sensing units 1130(1)~1130(N) corresponds to one of the plurality of video sources DS1~DSN. After the control unit 1020 receives the sensing signals S111~S11N generated by one of the sensing units 1130(1)~1130(N), the control switching unit 1010 displays the corresponding video sources DS1~DSN on the screen D.
舉例來說,當本實施例之視訊切換系統1100應用於賣場時,各個感測單元1130(1)~1130(N)係可設置於各種商品陳列處。當對應於各個商品之感測訊號S111~S11N皆代表「預定範圍內不存在物體」之狀態時,控制單元1020控制切換單元1010於螢幕D播放「各種商品連續廣告」之訊息。當對應於A商品之感測訊號S111代表「預定範圍內存在物體」之狀態時,控制單元1020控制切換單元1010於螢幕D播放「A商品廣告」之訊息。如此一來,螢幕D既可播放「各種商品連續廣告」之訊息,在顧客接近某一商品時,亦可在螢幕D播放「此商品廣告」之訊息。For example, when the video switching system 1100 of the embodiment is applied to a store, each of the sensing units 1130(1) to 1130(N) can be disposed at various merchandise displays. When the sensing signals S111 to S11N corresponding to the respective products represent the state of "there is no object in the predetermined range", the control unit 1020 controls the switching unit 1010 to play the message of "various commercial continuous advertisements" on the screen D. When the sensing signal S111 corresponding to the A product represents the state of "the object exists within the predetermined range", the control unit 1020 controls the switching unit 1010 to play the message "A product advertisement" on the screen D. In this way, the screen D can play the message of "continuous advertisement of various commodities", and when the customer approaches a certain product, the message "this product advertisement" can also be played on the screen D.
請參照第19圖,其繪示依照本發明第十二實施例之視訊切換系統1200之示意圖。本實施例之多電腦切換系統1200與第十實施例之多電腦切換系統1000不同之處在於:本實施例之視訊切換系統1200係以數個螢幕D1~DN、數個視訊源DS1~DSN及數個感測單元1230(1)~1230(N)為例作說明,其餘相同之處不再重述。Referring to FIG. 19, a schematic diagram of a video switching system 1200 in accordance with a twelfth embodiment of the present invention is shown. The multi-computer switching system 1200 of the present embodiment is different from the multi-computer switching system 1000 of the tenth embodiment in that the video switching system 1200 of the embodiment has a plurality of screens D1 to DN, a plurality of video sources DS1 to DSN, and A plurality of sensing units 1230(1) to 1230(N) are illustrated as examples, and the rest of the similarities are not repeated.
各感測單元1230(1)~1230(N)係對應於其中之一螢幕D1~DN,並設置於對應之螢幕D1~DN的附近。控制單元1020係根據感測單元1230(1)~1230(N)產生之感測訊號S121~S12N,控制切換單元1010於對應之螢幕D1~DN顯示視訊源DS1~DSN之一。Each of the sensing units 1230(1) to 1230(N) corresponds to one of the screens D1 to DN, and is disposed in the vicinity of the corresponding screens D1 to DN. The control unit 1020 controls the switching unit 1010 to display one of the video sources DS1 DSDSN according to the sensing signals S121 S S12N generated by the sensing units 1230(1) to 1230(N).
舉例來說,當本實施例之視訊切換系統1200應用於賣場時,各個感測單元1230(1)~1230(N)及對應之螢幕D1~DN係可設置於各種商品陳列處。當對應於A商品之感測訊號S121代表「預定範圍內不存在物體」之狀態時,控制單元1020控制切換單元1010於對應螢幕D1不播放任何訊息。當對應於A商品之感測訊號S121代表「預定範圍內存在物體」之狀態時,控制單元1020控制切換單元1010於對應A商品之螢幕D1播放「A商品廣告」之訊息。如此一來,各個螢幕D1~DN平時不播放訊息,僅在使用者接近對應之商品時,在螢幕D1、D2、或DN才播放「此商品廣告」之訊息。For example, when the video switching system 1200 of the embodiment is applied to a store, each of the sensing units 1230(1) to 1230(N) and the corresponding screens D1 to DN can be disposed at various merchandise displays. When the sensing signal S121 corresponding to the A product represents the state of "the object does not exist within the predetermined range", the control unit 1020 controls the switching unit 1010 not to play any message on the corresponding screen D1. When the sensing signal S121 corresponding to the A product represents the state of "the object exists within the predetermined range", the control unit 1020 controls the switching unit 1010 to play the message "A product advertisement" on the screen D1 corresponding to the A product. In this way, each screen D1~DN does not play a message at all times, and only the message of "this product advertisement" is played on the screen D1, D2, or DN when the user approaches the corresponding item.
