At present, the problem is mainly solved by adding a UPS (uninterrupted power supply) to the front end of the server, namely an uninterrupted power supply system.
In a power supply system with a UPS, mains supply is firstly connected into the UPS, then the UPS transmits power to the server, and when the mains supply is abnormal, the UPS switches the power supply system of the server to a standby power supply state. However, the electric quantity of the UPS storage battery is limited, and the server can only be maintained to work for a period of time after the mains supply is powered off, and when the electric quantity of the UPS storage battery is exhausted, the server still has a possibility of losing important data due to abnormal shutdown of the power failure, which brings huge loss to users.
The patent with publication number CN101895414A discloses a method for power down protection of a server power down protection system, which is to set a power down detection device on a UPS, when detecting that a mains supply is powered down, the UPS sends power down information to the server through an RS232 interface, and the server switches to an emergency working state after receiving the power down information, that is, a working state for data storage and emergency task processing is performed, thereby realizing power down protection of the server. The device for detecting power failure is arranged on the UPS, so that the UPS and the server need to be provided with communication connection for the server to know the power failure information, and the cost of the server power failure protection system is increased.

Detailed Description
Fig. 1 shows a schematic diagram of a server performing power protection through a UPS, where a commercial power is connected to the server through the UPS, and when the commercial power fails, the UPS may use a backup power supply to supply power to the server. The server is also provided with a network port connected with network equipment, and the network equipment directly obtains the power from the commercial power without obtaining the power through the UPS. When the mains supply is powered off or the voltage is unstable, the UPS can temporarily switch the power supply of the server to the standby power supply, and the power supply of the network equipment is not protected by the UPS, so that the network equipment can be powered off when the mains supply is powered off, and the power failure of the network interface of the server connected with the network equipment is caused.
Whether the network port of the server is powered down or not can be obtained through the following steps:
(1) running a network port information checking command on a server, and outputting a checked result to a physical file;
(2) analyzing the obtained physical file, and extracting the power-on/power-off state information of the server network port;
(3) and comparing the extracted current power-on/power-off state information of the server with the last extracted power-on/power-off state information, and if the information is different, changing the power-on/power-off state of the network port of the server.
Based on the principle, the invention provides a server protection method and device based on internet access perception, which judges whether a power supply source of a server is a standby power supply or not by detecting whether the internet access is in a power-on state or a power-off state. When the power supply of the server is a standby power supply, the server is switched to an emergency working state, namely a working state for storing data and processing emergency data, so that the server is protected. The present invention will be described in detail with reference to the accompanying drawings.
The method comprises the following steps:
the invention provides a server protection method based on internet access perception, which comprises the following steps:
(1) after the server is powered on, detecting whether all the network ports of the server are in a continuous power-down state;
(2) and when the state of the network port of the server is detected to be a continuous power-down state, the server is switched to an emergency working state.
Compared with the prior art that the commercial power failure detection device is arranged on the UPS, the invention judges whether the server is switched to the emergency working state or not by detecting the power failure state of the server network port, the device for detecting the power failure of the server network port is arranged on the server, and the server can directly obtain the power failure information, thereby saving the link of data transmission and achieving the purpose of saving cost.
The flow chart of the method for detecting whether the server network port is in the power-down state is shown in fig. 2, and the method comprises the following steps:
(1) after the server is powered on, detecting a network port of the server; when detecting that all network ports of the server are in a power-off state, starting timing by a first timer;
(2) before the first time timer reaches a preset first time threshold value, when the state of any one of the network ports is detected to be changed into a power-on state, resetting the first timer;
(3) judging whether the timing of the first timer reaches a preset first time threshold value, and judging that the server network port is in a continuous power-down state when the timing of the first timer reaches the first time threshold value;
(4) when the network port of the server is in a continuous power-down state, the mains supply is powered down, and a power supply of the server is a standby power supply; at the moment, the server is switched to an emergency working state, the emergency task is processed, the data are stored, and meanwhile, the first timer is reset.
In this embodiment, the first timer is used to provide a basis for determining that the server network port is powered off continuously, so as to avoid erroneous determination, for example, when the server network port is in a power-off state temporarily due to some reason, if the first timer is not set, an error of power-off of the server network port is made, and stability of server operation is affected. As another embodiment, when the performance of the server port is very stable, the first timer may not be set, and when the server port is in a power-down state, the power-down of the server port is directly determined.
Because when the mains supply is unstable, the power supply of the server is also switched to the standby power supply, and when the mains supply is unstable, the server also needs to be switched to an emergency working state. Therefore, the present invention further provides a method for determining instability of mains supply, wherein a flowchart is shown in fig. 3, and the method comprises the following steps:
(1) starting a second counter of the first timer after the server is powered on;
(2) before the timing of the first timer reaches a preset first time threshold, when the network port of the server is changed from a power-off state to a power-on state, the count value of the second counter is increased by 1;
(3) when the timing of the first timer reaches a preset first time threshold value, the value of the second counter is cleared;
(4) when the count value of the second counter reaches a preset second digital threshold value, the commercial power supply is judged to be unstable, at the moment, the server is switched to an emergency working state, the emergency task is processed, the data are stored, and meanwhile, the second counter is reset.
In this embodiment, the first timer and the second counter are used to provide a basis for determining the instability of the mains supply. If the judgment on the stability of the mains supply is not set, because the power supply of the server is the standby power supply when the mains supply is unstable, under the condition that the mains supply is unstable for a long time, the server still loses data when the electric energy of the standby power supply is exhausted, and the loss is brought to users. Therefore, the scheme of the invention is more perfect by arranging the step of judging the stability of the mains supply.
