Description

Computer shutdown safety buffer device

technical field

The invention relates to a computer shutdown safety buffer device. When the computer is touched by any factor, the external user power switching switch, the computer will not immediately stop supplying power, and the pressing signal of the external user power switching switch will notify the computer shutdown safety buffer The device is used to store the files in use, and at the same time execute the safe shutdown process sequentially. After the safe shutdown process is completed, the shutdown safety buffer device controls the computer to shut down to stop the power supply.

Background technique

At present, when the computer processing operation is being executed, many operating system programs and application programs must be temporarily stored in some volatile memory registers in order to obtain fast calculation processing. Careful children), the data temporarily stored in the volatile memory for processing will disappear or even damage the user’s application program and cause damage to the operating system due to lack of subsequent power supply. Slight damage may be able to It is repaired by the operating system through the inspection action of security repair, but similar damages will cause the computer to crash for too many times, so it cannot be turned on again, and the system must be reinstalled to solve it, which causes inconvenience in use.

If the operating system can be reinstalled, it will only cause inconvenience and waste of time. However, if the software developed by the user or important files in the operation, the permanent loss of data due to improper shutdown, the cost can be large or small. A safe computer system must take into account the losses caused by these accidents. Present computer control switch, usually all is that a button is pressed once to start and shut down the computer. For booting, any pressing will not cause damage to the system. However, if the switch is pressed suddenly during use, the user's files may be damaged, hard work will go to waste, and the system may be damaged and cannot be turned on normally.

In view of this, the inventor researched and innovated a computer shutdown safety buffer device. When the computer is touched by any factor, the computer will not stop supplying power immediately. At the same time, the safe shutdown process is executed sequentially. After the process is executed, the shutdown safety buffer device controls the computer to actually shut down and stop the power supply.

Currently, if the shutdown is caused by a power outage, it can be solved by installing an uninterruptible power system (UPS). When the uninterruptible power system (UPS) detects a power outage, it will send out a warning signal to notify the user, and quickly perform the correct shutdown process to save the data of the application program and perform the system shutdown operation safely. On the one hand, it provides enough time for the user to perform the above operation with the electric energy stored by itself. However, if the power switch of the host computer is accidentally touched and the power supply disappears, the system cannot be normally shut down, resulting in system damage and loss of user application data. Although the chance of the power switch of the host computer being accidentally touched is quite small in general, it should be avoided if it can be avoided. On the other hand, if there is an information computer product, if there is no suitable display device for the user to judge the current system operation execution status of the hardware during use, the user will not dare to turn off the computer rashly, thereby causing trouble. In order to solve the accidents and puzzles listed above, there is currently no relevant device that can be handled conveniently. Therefore, the present invention proposes the architecture concept of a computer shutdown safety buffer device for the application of related computer products.

Detailed ways

Please refer to shown in Fig. 1, between the computer motherboard 11 of computer 1 and the power switch 12 operated by the external user, a shutdown signal input line 21 is used to connect with a shutdown safety buffer chip 2; wherein the computer motherboard 11 is connected to the shutdown safety The buffer chips 2 are connected by a power-off instruction signal line 22 and a power-off inquiry signal line 23; an internal power switch 3 is provided between the computer 1 and the power connector 13, which are respectively connected by wires 31 and 32, and the wires 31 are reused. Another wire 33 is connected with the shutdown safety buffer chip 2; the selector 4 controlled by the internal power supply switch is provided between the shutdown safety buffer chip 2 and the internal power switch 3; it is connected by power control output lines 41, 42 respectively; The board 11 and the selector 4 are connected by another power control output line 14 . The power connector 13 is externally connected to a power cord 15, which can directly provide the required power, or be connected to an uninterruptible power supply system 5; Use the presence or absence of this power supply as the second signal input of the computer shutdown safety buffer device (the first signal input is the power switch on the computer host), if after comparison, it is found that the external power supply is interrupted for some reason, thus activating the uninterruptible power supply. For the standby power supply system of system 5, the computer shutdown safety buffer device outputs a shutdown signal, requiring the system to perform a safe shutdown action to protect the safety of the computer system.

As shown in Figure 2, the working process of the computer shutdown safety buffer device of the present invention is as follows:

When the user presses the switch, two situations can occur:

1. Form a boot

At this time, the shutdown safety buffer device can generate a signal to the computer mainboard, and check whether the hardware is already starting from the judgment of the signal.

Second, the formation of shutdown

1. At this time, the shutdown safety buffer device can generate a signal to the computer motherboard, and check whether the hardware is starting up from the judgment of the signal; if it is already starting up, then:

2. The shutdown safety buffer device outputs a shutdown indication signal to the computer motherboard controller through a signal connection connected to the computer motherboard (take the Windows operating system as an example, obtain the start-shutdown signal), and the computer motherboard controller responds accordingly Generate an inquiry signal response to the shutdown safety buffer device;

This inquiry signal is the same as the shutdown signal prompted by the general operating system. If there is a display screen, the user can decide whether to really shut down or cancel the shutdown action by interacting with the screen prompt when the system prompts to shut down, because sometimes it is The power push switch is triggered by a malfunction, and the user does not really want to shut down the machine to end the work. At this time, the user can be given the opportunity to decide whether to shut down or not. On the other hand, if the user does not respond within the set time (such as a few seconds) when the prompt signal appears, the shutdown safety buffer device will directly issue a shutdown command for the user, and then:

3. The shutdown safety buffer device then responds to the computer motherboard controller shutdown confirmation signal, and then:

4. Control devices such as the computer motherboard CPU check whether there is currently an executing user application program. If any of these applications are still running, then:

5. The computer motherboard controller generates an instruction for file storage to the shutdown safety buffer device, and then:

6. Shut down the safety buffer device and then respond to the computer motherboard controller file storage confirmation signal, then:

7. The computer mainboard controller performs the storage of the user application program file and the correct closing procedure of the application program; after completion:

8. The main board controller of the computer then closes the system operation software, which includes the safe unmounting of peripheral hardware (un-mount), the closing of the system program and other related actions, after completion; then:

9. Turn off the power supply, complete the safe shutdown procedure in case of accidents, ensure the use of data and ensure the security of the system.

The program planning of the above-mentioned action flow can be as follows (please refer to the attachment, the attachment shows the computer program structure of the shutdown safety buffer device of the present invention):

If, input signal 1 is generated by pressing the power switch on the main system (If, input signal 1, generated by pushing the power switch on the main system);

If, the motherboard is powered off, there is no signal feedback from the motherboard (If, MB power off, signal feedback from motherboard);

Then, power on, connect the power supply (Then, power on, connects the power source);

Otherwise, the motherboard is turned on, and the motherboard provides a signal (Else, MB power on, signal provided form motherboard);

Then, start the shutdown process (Then, shutdown process is triggered);

The motherboard requires a shutdown action (Shutdown action request was provided by motherboard).

Example 1. "Yes", accept the request, and the user proposes (Case 1. "Yes" to accept the request, provided from user);

Save the user file;

Shutdown the OS system.

Example 2. "No", reject the request, the user proposes (Case 2. "NO" to reject the request, provided from user);

Return to the normal using condition.

Case 3. "Delays" a few seconds, such as 10 seconds (Case 3. "Delays" a few seconds, 10seconds, for example);

Same process as case 1, random condition (Same process as case 1, default condition);

Otherwise, input signal 2, generated by abnormal shutdown power supply (Else, input signal 2, generated by power source abnormal shutdown);

Then, shut down (Then, power off);

The same process steps as example 1 (Same action procedure as case 1).

When the computer shutdown safety buffer device of the present invention is connected to an uninterruptible power supply system 5, it is used. When the power supply used is suddenly interrupted, if there is no protection of the uninterruptible power supply system 5, its situation is the same as pressing the power switch of the computer, which will cause damage to the user files and operating system files. Although the uninterruptible power system 5 has the function of protecting the computer system, it is not for the purpose of providing long-term operating power. Generally, if there is a power interruption, the only action of the user is to perform a safe shutdown instead of relying on the uninterruptible power system. 5. The power provided continues to work (generally commercially available UPS products, the power supply time is about five minutes or more). The reason why the uninterruptible power system 5 has different power specification products at present is that one purpose is to supply computer system clusters with large power consumption; If a computer system can combine the design of the computer shutdown safety buffer device with the uninterruptible power supply system 5, then when the external power supply is interrupted, the computer shutdown safety buffer device can immediately and automatically perform a safe shutdown process without waiting for an instruction from the user. Quick and effective. If it is used in a stand-alone desktop personal computer or a portable mobile computer, the operating system is generally relatively simple, and there is usually only one user at the same time. If it is used for this purpose, the backup power of the uninterruptible power system 5 only needs to be sufficient for the system for 3 minutes. (less than five minutes) or so will do. At this time, the backup power of the uninterruptible power system 5 can be minimized. Compared with the current uninterruptible power system 5 with higher power in the market, its price can also be economical.

The shutdown safety buffer device of the present invention is connected with the hardware of the original motherboard as follows, as shown in Figure 1:

1. When the computer is connected to an external power supply, the computer shutdown safety buffer chip 2 (Power OffSafety Buffer Chip, POSBC) is supplied with power at the same time, but the computer motherboard 11 (Motherboard, MB) has not yet been connected to the power supply for activation.

2. When the user decides to start the machine, press the internal power switch 12 to start the machine. At this time, the power-off safety buffer chip 2 (POSBC) receives an input signal, and then the power-off safety buffer chip 2 (POSBC) is connected through the wiring, that is, the machine is turned off. The indication signal line 22 outputs a signal to the computer motherboard 11 to compare the execution status of the host computer system. If it is shown that the host computer was not powered on before, the power-off security buffer chip 2 (POSBC) sends two signals in sequence:

a. Control the selector 4 and the power switch 3 through the internal power switching switch, so that the external power supply can be connected with the computer main board 11 (MB), so that the main board can obtain power supply.

b. Send a signal to the main board (so the main board has received power at this time, and the controller can accept the signal) to activate the main board, so that the operating system starts to operate. Then the user can continue to use the information computer equipment normally.

Three, when the user decides to shut down (or because of carelessness), then press the user's internal power switch 12 to shut down. If the system in the past, there is no shutdown safety buffer chip 2 (POSBC) protection, the computer motherboard 11 The power supply is directly lost, data is lost, and the operating system is damaged.

Under the protection of the shutdown security buffer chip (POSBC), the process description is as follows:

1. The power-off security buffer chip (POSBC) communicates with the motherboard controller according to the shutdown instructions and executes various actions accordingly.

2. When the operating system running on the main board completes the safety process, the operating system outputs a signal indicating that the safety shutdown is complete, and at the same time outputs a signal to turn off the power supply to control the internal switch selector to disconnect the power supply.

4. Utilizing the chip architecture of the shutdown safety buffer device of the present invention, the designer can refer to the I/O design drawings of each main board to lead the required signal out and connect to the shutdown safety buffer chip (POSBC). Therefore, as long as the shutdown safety buffer chip (POSBC) If the number and connection shape of the signal pins of ) can be matched with the motherboard, it can be designed independently without changing the design of the motherboard. In the future, users can purchase this power-off security buffer chip (POSBC) and install it Based on the existing system to obtain the guarantee of shutdown safety buffer. Of course, the concept of the present invention can also be integrated into the design of the function of the power-off safety buffer device (POSBC) when the main board is designed, so that the main board is already equipped with the function of this power-off safety buffer, so it is not necessary to add additional Independent external safety off buffer device (POSBC).

The computer shutdown safety buffer device of the present invention, when the computer is touched by any factor, the external user power switching switch, the computer will not stop supplying power immediately, and the pressing signal of the external user power switching switch will notify the computer shutdown safety buffer chip to perform The storage action of the file in use is executed simultaneously with a safe shutdown process. After the safe shutdown process is completed, the shutdown safety buffer chip controls the shutdown of the computer to stop the power supply.

The computer shutdown safety buffer device of the present invention, the number and connection shape of the signal pins of the shutdown safety buffer device can be matched with the motherboard, and the product with the computer shutdown safety buffer device can be assembled without changing the design of the motherboard. Then the existing computer users can install the shutdown safety buffer device in the existing computer system to obtain the protection of the shutdown safety buffer.

The computer shutdown safety buffer device of the present invention can integrate the function of the computer shutdown safety buffer device in the manufacture of the motherboard, so that the motherboard can have the computer shutdown safety buffer function, and there is no need to add an independent shutdown safety buffer device to the computer. system.

The computer shutdown safety buffer device of the present invention, which is matched with the uninterruptible power system 5, can immediately perform the function of normal shutdown, and the function of the uninterruptible power system 5 is the same as that of the current commercially available ones, but it can be supplied to a stand-alone computer system in about five minutes with special specifications (Typically about two minutes to five minutes); when the computer shutdown safety buffer device is used together with the uninterruptible power supply system 5, because it can immediately perform the normal shutdown function and shut down in the shortest time, it is particularly emphasized that all Uninterruptible power system with this low power characteristic.
