[Previous technology] In recent years, a network wake-up mechanism has been developed, so that users can wake up the computer system on the other end through a remote terminal server. The network interface card (NIC) used by this computer system must have the ability to wake up the remote terminal server for the computer system to have the above functions. Generally speaking, there are two types of power used in computer systems, one is core power ′ and the other is SUSpend power. When the AC power plug of the computer system is plugged into AC power, although the computer system's power switch has not been turned on, backup power has been provided to the computer system. In addition, after the computer system is turned on, when the computer system detects that some devices are in a non-use state, it can be set to a suspend state, and the supply of core power to these devices is stopped, and only the standby power is provided. In order to achieve the function of saving power. ^ When the electrical system is turned on, the Basic Input / Output System (BIOS) will execute ACPI (Advanced Configuration and Power Interface) routines to perform complete power management of the electrical 1228358 brain system. After powering on, the operating system can turn off peripherals that are not in use, or put the system into hibernation. After the user presses the keyboard or moves the mouse, the AcP] [program can automatically make the computer system get the core power supply again. The steps mentioned above to make the computer system get the core power supply again can also be accomplished by using the Wake-on-LAN method. By enabling the remote terminal of the network system to send a Wake-up packet to the network interface card, when the network interface card receives the Wake-up packet, it then sends a signal, namely a Power Management Event (PME) To the south bridge chip in the computer system to wake up the computer system. Furthermore, when the South Bridge chip in the computer system is set to a state that can receive the power management events transmitted by the network interface card, it must be performed after the basic input / output system executes the Acp ^ sequence of the boot process. That is, the user must press the power switch of the computer system. After the computer system is turned on and enters the boot material, the setting of the Nanqiao Daily Film can be completed. And ^ During the setting process, the large current of the core power must be used, which is not available from the backup power supply. Therefore, in the traditional method, when the computer system is not turned on, the Southbridge chip cannot respond to the power management events transmitted by the 罔 ^ ^ 罔 road interface card, that is, 々 十 ^ The system cannot be awakened through the network at this time. In other words, it is said that if the computer system has never been turned on, the computer system is a function.疋 Will not be able to be awakened by the network, and when the computer completes the booting action and has completed the computer system 1228358 has been set to accept the network, shouting Xiuzhuangzhuang can wake up from the etiquette, if the computer is normal at this time Shutdown, for example, when the machine is shut down or its AC power supply is improperly disconnected, will cause the electrical equipment and system to fail to respond to the above-mentioned power management events. At this time, although the backup power in the computer system still exists: the computer is awakened by the remote terminal's network wake-up packet. Traditionally, the user can only reset the computer system by manually pressing the computer's power switch, and then re-suppress the south bridge chip, so that the computer system can have the Wake-on-LAN function again. '[Summary of the Invention] As mentioned above, when a computer system is applied to a server system, since the feeder system [often multiple computer systems are installed on a rack, so if one of the computers is When a system crash occurs, it is more difficult for the user to reset the computer system of the crash. In view of this, the object of the present invention is to provide a Wake-on-LAN device. When a networked computer system is awakened by a network, a programmable control device is used to reset the computer system. Another object of the present invention is to provide a wake-on-network method. When a computer system crashes, it is determined whether the power can be reset by the wake-on-network according to the system system state data obtained by the monitored computer system. Moonwise system. Another object of the present invention is to provide a network wake-up method. This method can respond differently to different states of a computer system. To improve 1228358, it is clear that the Wake-up method cannot wake up a computer system that has crashed. , Systemic issues. The purpose of this month is to provide a programmable control device. 'This programmable control device uses its handshake agreement with the computer system to confirm whether the computer system is in a normal state. When the computer system is not in a normal state, In this state, the programmable control device can be used to reset the computer system. According to the above object of the present invention, a wake-on-network device is provided, which includes a programmable control device, a computer system, and an interface device. When the interface device receives a Wake-on-LAN packet, it sends a power management event signal to the programmable control device and the computer system respectively. If the computer system is in a normal state, such as a sleep state and a running state, when it receives the power management event signal, the computer in the sleeping state will start and resume to the running state, and the computer system in the running state will Continue to operate without being affected by this power management event signal. If the computer system is in an abnormal shutdown state, such as when it is down or its power supply has been improperly disconnected, then when the computer system receives this power management event signal, the Japanese watchman, its southbridge chip cannot make this power management event signal. Relative response. ^ The programmable control device of the present invention includes a receiving module, a handshake p,, X, and a reset module, wherein the receiving module is used to receive a power management event signal from the interface. The control logic of this programmable control device is that its handshake module uses a handshake protocol to communicate with the computer system to determine whether the computer system is in a normal state or an abnormal shutdown state. When this programmable! 228358 type control device receives the power management event signal, if the computer system is in a normal state at this time, the programmable control device will not reset the computer system. If the computer system is at this time In the abnormal shutdown state, the programmable control device resets the computer system using its reset module. According to a preferred embodiment of the present invention, the interface device is a network interface card. In addition, the programmable control device is a baseboard management controller (BMC) chip, usually an 8051 chip directly configured in the motherboard of the computer system, which is responsible for monitoring the system status of the entire computer system , And generate a system status data. Moreover, the computer system in this embodiment uses a south bridge chip to receive the aforementioned power control signal. When the handshake module finds that the computer system is in an abnormal shutdown state through the handshake protocol, and then cooperates with the system status data, it can be determined whether the system status of the computer system is suitable for resetting by using the network wake-up packet. . The programmable control device is configured to send a first

In this embodiment, the above-mentioned handshake protocol completes a signal by a register, and the computer and a second signal, both of which are alternately written into the temporary memory and the first signal has an opposite logical level. The logic level of the data has been maintained with the first message, that is, it has not been changed by the computer system to the second. It can be known that the computer system is in a different state at this time. It can be known from the above that the network wake-up device of the present invention is The operable logic set in the 1228358-type control device can enable a central control program or a server manager located at a remote terminal to directly use a network wake-up packet to reset a computer system in an abnormal shutdown state. In addition, with the monitoring module in the programmable control device, you can confirm whether the hardware equipment of the computer system has any problems before the above steps of resetting the computer system, in addition to avoid resetting the computer with problems in the hardware equipment The system causes greater losses, and it also eliminates the difficulty of resetting one of the multiple computers installed in the frame. [Embodiment] The following uses two embodiments to explain the network wake-up device of the present invention, wherein the normal state of the computer system is defined as including the operating state and the sleep state, and the sleep state includes the soft shutdown mode in the operation of the computer system ( softoffmode) and suspend mode. In addition, the abnormal shutdown state of a computer system is defined as including a down state or a state where its power supply is improperly powered off. Fig. 1 is a schematic diagram showing a preferred embodiment of the present invention, and Fig. 2 is a flowchart of the preferred embodiment in Fig. 1. Please refer to Figs. 1 and 2 for the following description. First, the remote terminal of the 'network system sends a Wake-on-LAN packet to the network interface card 104 (step 202). When the network interface card ι04 receives this Wake-on-LAN packet, a signal, namely a power management event (PME), is sent to the programmable control device 10 1228358 102a and the computer system 1 respectively. 6 (step 204). In this embodiment, the computer system 106 receives a power management event signal from the network interface card 04 using a south bridge chip (not shown). According to different states of the computer system 106, the present invention makes different corresponding steps (step 206). When the computer system 106 is in the running state and the day guard, the south bridge chip ignores the power management event signal, and the computer system 106 will continue to maintain the normal running state (step 212). When the computer system 106 is in the sleep state, the south bridge chip will wake up the computer system 106 after receiving the power management event signal, so that the computer system [% is activated and restored to the operating state (step 214). When the computer system is in an abnormal shutdown state, for example, when the computer system is shut down or its power supply is improperly powered off, after receiving this power management event signal, its south bridge chip cannot make a relative response to this power management event signal. Response (step 216). The programmable control device 102a in the present invention includes a receiving module 112 ', a handshaking module 114, and a reset module 116. The receiving module, and 11 2 are used to receive the above-mentioned electrical event messages from the network interface card}. The handshake module 14 will use a handshake protocol to communicate with the computer system 106 to determine whether the computer system 10 is in a normal state or an abnormal shutdown state. Regarding the master & 7 丨 上 t ^ ^ The handshake agreement will be described in detail later. Figure 3 is a flow chart showing the control logic of the programmable control device of the present invention. Dang Shibu Ke * # 』The private control device 102a receives power When managing the 1228358 event signal (step 302), if the computer system 10 is judged to be in a normal state by the handshake module 1 μ (step 304), the programmable control device 102a will not reset this. Computer system 106 (step 312). If this system is determined by the handshake module i 14 to be in an abnormal shutdown state (step 304), the programmable control device 102a will use it The reset module 116 resets the computer system 106 (step 314). FIG. 4 is a schematic diagram showing a preferred embodiment of the handshake protocol. In this embodiment, the handshake protocol is implemented by a register 4〇2. Programmable parameterized control device 102a is set to send Sending a first signal has a high logic level 1 and the electronic shame system 106 is set to send a second signal with a low "edit level 0", which are alternately written into the register 402. Therefore, when the logic level of the data stored in the register 402 is always the same as the logic level of the first signal (high logic level 1), it is not changed by the computer system 106 as expected. When the logic level (low level level 0) of the second signal is the same, it can be known that the computer system and the coffee system are in an abnormal shutdown state at this time. _ Figure 5 shows another preferred implementation of the present invention. Figure 6 is a schematic diagram of the preferred embodiment in Figure 5. Please refer to the following description, ..., Figures 5 and 6. The following examples are mainly used to explain this How to use it in a server system with multiple computers. When multiple computers are installed on a rack, and one of the computer systems is Ikuta Machine, the use of the invention can help The user judges and resets this crashed computer system. 12 j228358 The programmable control device 1 2b in Figure 5 has a monitoring module more than the controllable control device 1 2 2 in Figure 1. 1 22 and a data output terminal 1 24. In this embodiment, a baseboard management controller (Base A board management controller (BMC) chip is used as the programmable control device 102b in the present invention. The substrate management controller chip is usually an 8051 chip directly disposed on the mainboard of the computer system 106. The 8015 chip itself That is, it has a microprocessor, memory, and input / output ports' and is powered by suspend power. The baseboard management controller chip will collect information about system health and system status of the computer system 106. Corrective actions can be performed immediately when a serious event occurs. Usually, the system health monitoring function of the baseboard management controller chip is implemented in conjunction with multiple digital sensors, which can monitor different system voltages, temperatures, and fan speeds. The substrate management controller chip uses an active polling method to find out whether there is a sensor out of range among the plurality of sensors connected to it. And 'for the monitoring work to be effective', the substrate management controller chip can Configure according to different thresholds. For example, when the BMC wafer detects a certain When the temperature of a sensor exceeds a certain warning threshold, the speed of the fan corresponding to the position of the sensor will be increased. Furthermore, if the effect of the corrective action is not enough, the temperature exceeding a certain warning gate will Exceeds another emergency threshold, at this time the baseboard management controller chip will cut off the system power, record the event process and send a remote terminal 13 1228358 warning through the network. First, programmable control can be used to set up Zhilin to use its monitoring module i22, The system status data of the computer system 106 is transmitted to the remote terminal through the data output 缟 U4 (step 60): The brain system iG6 is in an abnormal shutdown state and is located at the second inspection of the remote terminal, such as central control The program or server manager can judge the status data to determine whether to reset the computer system 106 (step ^ 4). ',' Respectively discuss how to determine whether the computer system can be reset. If the system status data of the computer system 106 indicates that the computer system has a hardware failure, such as the failure of its cooling fan cannot effectively help the heat dissipation, or the voltage value of any line is incorrect, you must For further inspection and repair of the hardware equipment, the computer system 106 cannot be rashly reset (step 622). On the other hand, if there is no problem with the hardware of the computer system i 〇6, it is only caused by a certain noise (noise) to cause it to crash, or its power is improperly cut off. , But did not cause any harm to its hardware equipment, at this time, a wake-up packet can be sent to the network interface card 104 to reset the computer system 106 (step 612). ) Similarly, when the network interface card 104 receives the Wake-up packet, it sends a power management event signal to the programmable control device 102b and the computer system 1G6 (step 614). However, since the computer system 106 is already in an abnormal shutdown state, the power supply event signal transmitted directly from the network interface card 104 will not have any effect on the computer system. The programmable control device 10b of the present invention has used its handshake module 114 to confirm that the computer system 106 is in an abnormal shutdown state. Therefore, when the receiving module 112 of the programmable control device 102b receives the power management event signal from the network interface card 104, the programmable control device 102b uses its reset module 116 to reset this. Computer system 106 (step 616).
