Abstract

The present invention provides a computer power backup system and device. When the computer system loses power, a Battery Backup Unit (BBU) provides the power and maintains the power supply for a period of time; meanwhile, a Power Management Control Center sends the warning message to the enterprise clients for prompting immediate processing. When the period of losing power is over-long and there is no engineer to recover the power, if the Power Management Control Center detects the insufficient power of battery, it saves the data in the storage equipment securely by itself and turns off the system. After the power is recovered, the Power Management Control Center turns on the computer system, and charges the battery of Battery Backup Unit (BBU). Thus, the completeness and safety of system data are ensured by using this operation mode.

Description

201044748 VI. Description of the Invention: [Technical Field] The present invention relates to a computer power backup system and device, which utilizes a battery backup unit, a DC-to-DC converter, and a power monitoring management center to make a computer system When power is lost, the battery backup unit provides power for short-term maintenance, and the power monitoring management center sends a warning or saves the data securely in the storage device to ensure the integrity and security of the system data. Ο 【Previous technology】 In the era of rapid development of technology, computer servers need not only respond to the market demand of high efficiency and high stability, but also how to save a large amount of data completely and safely. The design needs to constantly pursue the direction of innovation. The general use of computer servers is used to process huge amounts of data. 'The data can be distributed online at any time, and these data contain records of the confidential files, business transactions, etc. of major companies, if the company plays the life center of the enterprise. The role of the computer server, because of the instability of the power system, can not completely preserve the information, then 'that* will have a major impact on the enterprise and the employees themselves, and some will even face the loss of the competitive advantage of the industry. The crisis that led to the collapse of Yan. In order to avoid the above non-recoverable situation, in addition to the responsibility of large-scale data center processing, the computer server needs to have a backup mechanism, in order to maintain the basic availability of the 201044748 system in the event of a power outage. The introduction of the "continuous power system" has become an important industry trend. Generally, the external power system (UPS) is connected to prevent the computer system from being interrupted due to the failure of the power system, or even the data disappears or the storage device is damaged. However, if the power supply of the computer is damaged, The system will still face the same problem. Due to institutional restrictions, the commercial uninterruptible power system (UPS) is bulky and costly. Not all enterprises will adopt it. Especially for small and medium-sized enterprises, the invention is mainly to provide a backup system. The power-off system UPS will automatically switch battery backup when the utility power disappears or the power supply fails. The system of the present invention can be used alone as an electric power standby system, and can also be used with a general uninterruptible power system to achieve Extend the service time of the computer server. The system of the invention can be designed to be embedded in the system of the computer server, and can detect the status of the system, the power supply and the battery at any time through the built-in power monitoring and management center, and monitor when the system loses power, The management system will send a warning to the enterprise user, requesting the backup operation of the data. If the user does not deal with the standby power of the computer server before the battery is exhausted, it can also be used with the management software setting to issue a safe shutdown to the operating system. Instructions. When the system restores power, the Power Monitoring and Management Center will automatically charge the battery. Under such a working emergency state cycle, the company's information will be optimally and completely protected. 4 201044748 [Description] The architecture of the computer power backup system and device design of the present invention is mainly divided into three parts, namely, Battery Backup Unit (BBU), DC-DC converter DC-DC Converter and matching. Computer Power Monitoring and Management Center (P〇wer

Management Control). The main function of the battery backup unit BBU is to provide power from the battery when the system loses power, so that the system will not shut down immediately. When the system resumes power, it can automatically charge the battery, so that the system can maintain the efficiency of protecting data.

The main function of the DC-to-DC converter is to convert the power provided by the power supply PSU or the battery backup unit BBU to provide power for the system's main board. The working principle of the computer power backup system and device of the present invention, when the system loses power, the battery backup unit BBU provides power and holds the maintenance period for the monitoring management system to send a warning message to the customer for immediate processing. When the power is lost for too long and no engineering personnel do the elimination, the monitoring management system detects that the battery power is insufficient, and will safely save the data in the storage device and perform the shutdown operation of the system, waiting for the power recovery, monitoring The management system can start from the (four) system and charge the battery of _, using this mode of operation to achieve the integrity and security of the protection data. The computer power backup system and device of the invention can be used as a continuous power plant or a backup device. The modularization mode thereof has a system that can be lightly applied in various servers of 5 201044748, and can maintain the original of each system. In the functional design case, the computer power backup system and device module of the present invention are connected in series with the server system through the control line and the power line. When the system loses power, it can continue to maintain for a period of time and pass through the monitoring. The management program allows the system to safely store data in the storage device. While the negative material is fully protected, and because of the modularized space-saving advantages, the computer power backup system and device can be completely covered in the system and can be maintained. The work room is neat and beautiful.
