【具体实施方式】请参图1所示,为本发明所提供的双热插拔IDE装置之控制电路框图。 [DETAILED DESCRIPTION Referring to Figure 1, a block diagram of a control circuit of the dual hot-swappable IDE device provided by the present invention. 该电路包括IDE控制器10、IDE连接器20、热插拔控制器30、第一、第二快速开关41、42及第一、第二IDE装置51、52,其中第一、第二IDE装置51、52可为IDE储存装置,例如IDE硬盘装置,在本实施例中,选取IDE硬盘装置为例作说明。 The circuit 10 includes, IDE connector 20, hot-swap controller 30, first, second fast switch 41 and the first and second IDE devices IDE controller 51, 52, wherein the first, second IDE devices 51 and 52 may be IDE storage device, such as IDE hard disk device, in the present embodiment, the selected IDE hard disk device as an example for illustration. 第一、第二IDE硬盘装置51、52分别与第一、第二快速开关41、42电性连接。 The first, second IDE hard disk devices 51 and 52 are respectively connected to the first, second fast switch 41 electrically. 电源供应器60通过第一、第二电源开关61、62分别对第一、第二IDE硬盘装置51、52供电。 Power supply 60 through the first and second power switches 61 and 62 of first and second IDE hard disk device 51, power supply. 本实施例中,各电路组件均采用低态触发,即对其施加低电平(如逻辑“0”)信号时动作,施加高电平(如逻辑“1”)信号时不动作。 When an operation signal according to the present embodiment, each of the circuit components are toggles low, i.e. low level is applied thereto (e.g., a logic "0"), applies a high level (e.g., logic "1") is not an operation signal.

IDE控制器10通过IDE线缆(未图示)将IDE总线信号(IDEBus Signal)传送至IDE连接器20,该IDE总线信号包含地址信号、数据信号及控制信号等。 IDE controller 10 (not shown) signals the IDE bus (IDEBus Signal) transmitted through a cable to the IDE IDE connector 20, the IDE bus signal comprises an address signal, data and control signals and the like. 从IDE连接器出来的IDE总线信号将分别传送至第一、第二快速开关41、42。 Out of the IDE connector IDE bus signals are respectively transmitted to the first and second switches 41, 42 quickly. 第一、第二快速开关41、42通过开启或关闭从而允许或阻止IDE总线信号传送至第一、第二IDE硬盘装置51、52。 First and second fast switch 41 by opening or closing to allow or block the signal transmitted to the first IDE bus, the secondary IDE hard disk device 51, 52. 该二快速开关41、42在非工作状况下均为关闭状态,且不同时开启,当其中一个开启,另一个则处关闭状态。 The two fast switches 41, 42 are in the non-closed state operating conditions, are not simultaneously turned on, when one is turned on, the other is closed.

在第一、第二IDE硬盘装置51、52均连接于电路的情况下,用户决定对哪一IDE硬盘装置进行存取将藉由IDE控制器10的控制实现。 In the first case, where the second IDE hard disk devices 51 and 52 are connected to the circuit, which the user decides to access the IDE disk apparatus implemented by the control of the IDE controller 10. 例如,若决定存取第一IDE硬盘装置51,IDE控制器10发出MON=0的控制信号,该控制信号通过IDE连接器20传送至热插拔控制器30。 For example, if the first IDE hard decision means 51 is accessed, IDE controller 10 issues a control signal MON = 0, the control signal transmitted through the IDE connectors 20 to 30 hot-swap controller. 热插拔控制器30则向第一电源开关61发出PowerON=0的控制信号,使第一电源开关61开启,电源供应器可对第一IDE硬盘装置51供电;热插拔控制器30同时向第一快速开关41发出SwitchON=0的控制信号,使第一快速开关41开启,从而IDE总线信号得以传送至第一IDE硬盘装置51。 Hot swap controller 30 a control signal is issued PowerON = 0 to the first power source switch 61, the first power switch 61 is turned on, the power supply can power the first IDE hard disk device 51; hot swap controller 30 simultaneously fast switch 41 issues a first control signal SwitchON = 0, the first switch 41 is turned on quickly, so that the IDE bus signal is transmitted to the first IDE hard disk device 51. 此时IDE控制器10未发出SON=0的控制信号,使得热插拔控制器30亦未发出SwitchON=0的控制信号至第二快速开关42,第二快速开关42依然保持关闭状态,IDE总线信号无法通过,是以不能对第二IDE硬盘装置52进行存取。 At this time, the IDE controller 10 does not emit the control signal SON = 0, so that the hot swap controller 30 nor the control signal sent SwitchON = 0 to the second fast switch 42, a second fast switch 42 remains closed, IDE bus signal can not pass through, can not be accessed is a second IDE hard drive device 52.

相应地,若决定对第二IDE硬盘装置52进行存取,则IDE控制器10向第二电源开关62发出PowerON=0的控制信号,使第二电源开关62开启,电源供应器可对第二IDE硬盘装置52供电;然后发出SON=0的控制信号,使第二快速开关42开启,IDE总线信号传送至第二IDE硬盘装置52。 Accordingly, if the second decision means 52 for accessing IDE hard drive, the IDE controller 10 sends a control signal PowerON = 0 to the second power switch 62, the second power switch 62 is turned on, the power supply may be on a second IDE hard drive power supply device 52; and then issue a control signal SON = 0, the second fast switch 42 is turned on, a signal is transmitted to a second IDE bus IDE hard disk drive 52. 此时第一快速开关41因无控制信号触发,处于关闭状态,故不能对第一IDE硬盘装置51存取。 At this time, the first switch 41 is fast because there is no control signal is triggered, in the off state, it can not access to the first IDE hard disk device 51.

进行热插拔操作时,第一、第二IDE硬盘装置51、52可将其状态信息通知予热插拔控制器30,即当其中之一IDE硬盘装置热拔出时,该IDE硬盘装置发送MPresent=1(或者Spresent=1)的信号至热插拔控制器30;当热插入一IDE硬盘装置时,所述IDE硬盘装置将发送MPresent=0(或者Spresent=0)的信号至热插拔控制器30。 When the hot-swap operation, the first, second IDE hard disk devices 51 and 52 can be hot-swap state information notification to the controller 30, i.e., when one of the IDE hard disk device wherein heat removed, the IDE hard disk device transmits MPresent = 1 (or Spresent = 1) hot-swap signal to the controller 30; signal when a hot-plug IDE hard disk apparatus, the IDE hard disk device transmits MPresent = 0 (or Spresent = 0) to the hot-swap The controller 30.

请参图2所示,为本发明所提供之热拔出一IDE装置之流程图,例如若将工作中的第一IDE硬盘装置51从电路中拔出,则首先执行步骤71,第一IDE硬盘装置51将发出MPresent=1的信号至热插拔控制器30。 Referring to FIG. 2, the present heat provided by means of a pull IDE flowchart invention, for example, if a first IDE hard work apparatus 51 is pulled out from the circuit, the first step 71, a first IDE hard disk device 51 will signal MPresent = 1 to the hot-swap controller 30. 接着执行步骤72,热插拔控制器30发送SwitchON=1的控制信号至第一快速开关41,第一快速开关41关闭,使得IDE总线信号无法继续传送至第一IDE硬盘装置51。 Then, step 72, the controller 30 sends a hot plug SwitchON = 1 control signal to the first fast switch 41, a first fast switch 41 is closed, so that the signals can not be passed on the IDE bus to the first IDE hard disk device 51. 再执行步骤73,热插拔控制器30发出PowerON=1的控制信号至第一电源开关61,第一电源开关61关闭,电源供应器60停止对第一IDE硬盘装置供电。 And then the step 73, hot swap controller 30 PowerON = 1 control signal to the first power source switch 61, a first power switch 61 is closed, the power supply 60 stops power supply to the first IDE hard disk device. 然后执行步骤74,热插拔控制器30发出MPresnet=1信号经由IDE连接器20传送至IDE控制器10,告知IDE控制器10不再发送IDE总线信号。 Then step 74, hot swap controller 30 MPresnet = 1 signal is transmitted via the IDE connector 20 to the IDE controller 10, the IDE controller 10 to inform the IDE bus signal is no longer sent. 热拔出第二IDE硬盘装置52的控制过程类似,此不赘述。 A second control process heat extraction IDE hard disk device 52 is, like not described herein.

请参第三图所示,系本发明所提供之热插入一IDE装置之流程图,例如若再将第一IDE硬盘装置51热插入电路中,则首先执行步骤81,第一IDE硬盘装置51将发出MPresent=0的信号至热插拔控制器30。 Referring to FIG. Third, the IDE flowchart of a system provided by means of thermal insert of the present invention, for example the IDE hard disk 51 if more heat the first circuit device is inserted, the first step 81, a first IDE hard disk device 51 MPresent = 0 will signal the controller 30 to the hot-swap. 接着执行步骤82,热插拔控制器30发出PowerON=0的控制信号至第一电源开关61,第一电源开关61开启,电源供应器60开始对第一IDE硬盘装置供电。 Then, step 82, hot swap controller 30 PowerON = 0 control signal to the first power source switch 61, a first power switch 61 is turned on, the power supply 60 begins to supply a first IDE hard disk device. 然后执行步骤83,热插拔控制器30发出MPresnet=0信号经由IDE连接器20传送至IDE控制器10,告知IDE控制器10开始发送IDE总线信号。 Then step 83, hot swap controller 30 MPresnet = 0 signal is transmitted via the IDE connector 20 to the IDE controller 10 to inform the IDE controller 10 transmits the start signal IDE bus. 热插拔控制器30此时可接受IDE控制器10所发送之MON=0的控制信号,来发送SwitchON=0的控制信号至第一快速开关41,第一快速开关41开启,使得IDE总线信号得以传送至第一IDE硬盘装置51。 At this time, the MON acceptable hot swap controller 30 IDE controller 10 transmits the control signal = 0, a control signal is transmitted SwitchON = 0 to the first fast switch 41, the first switch 41 is turned on quickly, so that the IDE bus signals It is transmitted to the first IDE hard disk device 51. 热插入第二IDE硬盘装置52的控制过程类似,此不赘述。 IDE hard disk inserted into the second thermal control means 52 is similar to the process is not mentioned here.
