具体实施方式 detailed description

[0019]请参见图1,本发明的电源供应系统100包括电源供应器110、多个电路单元120以及时序控制电路130。 [0019] Referring to FIG. 1, the power supply system 100 according to the present invention includes a power supply 110, a plurality of circuit unit 120 and a timing control circuit 130.

[0020]电源供应器110与外界电源相连接,该电源供应器110通常包括一个交流-直流转换器,用以将外界的市用交流电转换成直流电,用以为后续的电路单元120供电。 [0020] The power supply 110 is connected to the external power supply, the power supply 110 typically includes an AC - DC converter for converting the external AC power to DC city, a power supply 120 that the subsequent circuit unit. 该电源供应器110可进一步包括一个控制端111,该控制端111与时序控制电路130相连接并记录电路单元120异常状态的发生。 The power supply 110 may further include a control terminal 111, the control terminal 111 is connected to the timing control circuit 130 and record the occurrence of an abnormal state circuit unit 120.

[0021]所述多个电路单元120可以是内存、CPU、硬盘或主板的南桥或北桥电路等。 [0021] The circuit unit 120 may be a plurality of memory, CPU, hard disk, or the motherboard Northbridge or Southbridge circuits and the like.

[0022] 该时序控制电路130连接在电源供应器110和多个电路单元120之间,用于分别控制电源供应器110按次序为该多个电路单元120供电。 [0022] The timing control circuit 130 is connected between the power supply 110 and a plurality of circuit units 120, 110 for respectively controlling the power supply in sequence for a plurality of power supply circuits 120 units. 时序控制电路130包括时序控制器131及多个开关单元132,所述多个开关单元132串联在电源供应器110和该多个电路单元120的电连接线路之间,通过时序控制器131控制该多个开关单元132的开启和关闭,从而实现利用电源供应器110在按次序分别为该多个电路单元120供电的目的。 The timing control circuit 130 includes a timing controller 131 and a plurality of switching units 132, 132 of the plurality of switching units connected in series between the power supply line 110 and is electrically connected to the plurality of circuit unit 120 by the timing controller 131 controls the a plurality of switching the opening and closing unit 132, thereby realizing the power supply 110, respectively, using for this purpose a plurality of power supply circuits 120 units in sequence. 同时,当任意一个电路单元120有异常发生时,所述时序控制电路130将记录该异常状态的发生,并且关闭和锁定电源供应器110,使电源供应器110无法以正常方式再次启动。 Meanwhile, when there is any abnormal circuit unit 120, the timing control circuit 130 to record the occurrence of the abnormal state, and closed and locked the power supply 110, 110 so that the power supply can not be started again in a normal manner. 该时序控制器131具有一个存储单元133,当电路单元120正常工作时,该存储单元133存储第一数据“O”;当任意一个电路单元120有异常发生时,该存储单元133存储第二数据“I”。 The timing controller 131 has a storage unit 133, when the normal operation of the circuit unit 120, the data storage unit 133 stores a first "O"; when any one abnormal occurrence circuit unit 120, the second data storage unit 133 stores "I". 所述存储单元133以非易失性存储器的方式记录电路单元120异常状态的发生。 The storage unit 133 in the nonvolatile memory of the occurrence of an abnormal state recording circuit unit 120. 在整个电源供应系统100开启时,电源供应系统100首先为时序控制器131供电。 When the entire power supply system 100 is turned on, the power supply system 100 is a timing controller 131 is first powered. 然后该时序控制器131检测存储单元133的存储状态,若存储单元133存储第一数据“O”,该时序控制器131控制开关单元132为电路单元120供电;若存储单元133存储第二数据“I”,该时序控制器131关闭电源供应器110。 Then the timing controller 131 detects the storage state of the storage unit 133, if the data storage unit 133 stores a first "O", the timing controller 131 controls the switching unit 132 is a unit power supply circuit 120; if the second data storage unit 133 stores " I ", the timing controller 131 off the power supply 110. 即,当电路单元有异常状态发生并被存储单元133所记录后,即使关闭电源供应系统100内所有的电源,亦无法消除该存储单元133的存储状态,从而防止用户再次启动电源供应器110时,电源供应器110直接为电路单元120供电,使到已经发生故障的电路单元120发生更大的损害。 That is, when the abnormal condition occurs the circuit unit and the storage unit 133 records, even when power off all of the power supply system 100, will not be able to eliminate the storage state of the memory cell 133, thereby preventing the user again starts the power supply 110 , the power supply 110 directly to the power supply circuit unit 120, Shidao circuit has failed unit 120 greater damage to occur.

[0023]可见,在本发明的电源供应系统100中,当任意一个电路单元120发生故障后,用户不能通过正常开机的方式再次启动电源供应器110,以防止发生故障的电路单元120因再次通电而冒烟或者起火,从而影响该电源供应系统100的安全性能。 [0023] visible, 100 of the power supply system of the present invention, when any one of the circuit unit 120 fails, the user can not normally boot method again starts the power supply 110 to prevent the circuit failed unit 120 by energization again while smoke or fire, thus affecting the safety of the power supply system 100. 因此,在电路单元120发生故障后,用户需要将该电子产品送至维修处检修,直至维修工程师经检修无误后,由维修工程师清除存储单元133所存储的数据,从而使电子产品可继续正常使用。 Accordingly, the circuit unit 120 after the failure, the user needs to access the electronic product to a service until the service engineer after overhaul correct, clear data stored in the storage unit 133 by the service engineer, so that the electronic item continue using .

[0024] 所述电源供应系统100可进一步包括一个第二电源供应器140,如图2所示。 The [0024] power supply system 100 may further comprise a second power supply 140, as shown in FIG. 该第二电源供应器140可单独为时序控制电路130供电。 The second power supply 140 may be a separate power supply for the timing control circuit 130. 使得时序控制电路130可以保持对电源供应器110的锁定状态,从而实现使电源供应器110无法为后续的多个电路单元正常供电。 Such that the timing control circuit 130 may maintain the power supply 110 to the lock state, in order to achieve that the power supply 110 can not follow the normal power supply to a plurality of circuit units.

[0025]应该指出,上述实施方式仅为本发明的较佳实施方式,本领域技术人员还可在本发明精神内做其它变化。 [0025] It should be noted that the above-described embodiments are merely preferred embodiments of the invention, those skilled in the art may make other variations within the spirit of the present invention. 这些依据本发明精神所做的变化,都应包含在本发明所要求保护的范围之内。 These changes made according to the spirit of the present invention, the present invention is intended to be included within the scope of the claims.
