Detailed Description
The technical means adopted by the invention to achieve the predetermined object of the invention are further described below with reference to the drawings and the preferred embodiments of the invention.
As shown in fig. 1, an embodiment of the present invention provides a computer failure recovery method, including the following steps:
step 101, monitoring a current value and a voltage value of a computer;
in this step, the monitored computer host power supply supplies power to the computer fault recovery device to get power, and a one-to-one configuration mode is adopted. The working state of the computer host is judged by monitoring the working current and voltage changes of the power supply of the computer host, including a normal working state and a dormant standby state. Dead halt state (program loop).
Step 102, when the current value reaches a current alarm value, controlling the computer to restart; when the computer is judged to be failed to restart, the restarting period is prolonged, the restarting mode is changed, and then the computer is controlled to restart; the restarting mode comprises power-off restarting and mechanical restarting; when the voltage value reaches the voltage alarm value, the power supply is cut off and an alarm signal is sent to a remote place through the remote transmission channel. When the voltage returns to normal, the power supply is automatically switched on to restart the computer.
In step 102, alarm values for the host current and voltage of the computer are preset. And judging whether the computer is in a fault state or not according to the alarm value. The fault state here refers to a sleep standby state, a dead halt state, or a voltage loss state.
The current of the host is usually higher than the normal current value in the dead halt state, so that the judgment is avoided by mistake, and the monitoring current value is usually higher than the normal current value for a certain time. The current in the sleep standby state is that the whole machine does not work, but the current is much smaller than that in the normal work to maintain the minimum system current of the machine. Therefore, here, a first threshold value and a second threshold value are preset, and the first threshold value is larger than the second threshold value. Here, the first threshold is a current threshold for normal operation, and the second threshold is a current threshold for standby operation. When the microprocessor monitors that the current value is greater than a first threshold value within preset time, the computer is judged to be in a halt state, and when the monitored current value is less than a second threshold value, the computer is judged to be in a dormant standby state. And when the monitored current value is larger than the first threshold value within the preset time or the monitored current value is smaller than the second threshold value, executing restart operation on the computer.
Since the normal operating current, the standby operating current and the dead halt state current of different devices are different, a normal operating current threshold (a first threshold) and a standby operating current threshold (a second threshold) need to be recorded when the system is used and deployed. In an optional embodiment of the present invention, the method for determining the first threshold and the second threshold is as follows:
after the equipment is put into use, a deployment process is started through a set port, wherein the set port can be accessed by a software interface or can be directly started by a physical key. When the equipment enters a deployment program, the equipment starts to record a current value and simultaneously sends out a prompt to remind the equipment connected by manual operation to enter a normal working state, the system continuously monitors and records the current, a data segment with stable current (the current is in an international unit system by taking a time axis as an abscissa, and the current has a fitting curve with the length not less than 20s and the included angle between the fitting curve and a horizontal line is not more than 5 degrees) is taken as a first reference threshold value C1, and the reference threshold value C1 is multiplied by an adjustment coefficient K1 to obtain a normal working current threshold value H1. The adjusting coefficient K1 is between 1.2-1.8, and is manually adjusted according to the current using state. The process of recording the standby working current is similar, an operator is reminded to enable the computer to enter a standby state, the current value is continuously monitored, the arithmetic mean value of a data segment with stable current (the current is abscissa time axis, the current is ordinate time axis, the included angle between a fitting curve with the length not less than 20s and a horizontal line is not more than 5 degrees) is taken as a reference threshold value C2, the reference threshold value C2 is multiplied by an adjusting coefficient K2, and the standby working current threshold value H2 is obtained. Wherein the adjusting coefficient K2 is between 0.8-1.3, and is manually selected and adjusted according to the current use state.
The restart mode includes a mechanical restart and a power-off restart. Wherein, the mechanical restart means that a mechanical device is used to impact (press) a computer reset key or a power key to start the computer. The mechanical restarting execution device is provided with a manual button which can press (operate) a computer reset key or a power supply key, and the power-off restarting refers to delayed power restoration restarting after a working power supply is cut off by a relay.
In this step, when determining whether the restart is successful, it is mainly determined whether the change dynamics of the operating current of the computer conforms to a normal operating mode, specifically including obtaining a current value after the restart, and determining that the restart fails when the current value fails to meet the current threshold of the startup control process, the startup state, and the operating state. If the process is restarted successfully, starting from the restart signal, in a restart period, a very low current point (start-up control process), current continuously rises and stabilizes the dynamic change process of a high power point (start-up state), and finally, a stable normal working current is obtained. And if the last stable normal working current is not monitored in the restart period, the restart failure is indicated.
And when the restart is determined to fail, prolonging the restart period, changing the restart mode, and executing the restart operation until the restart is successful. And when the restarting mode is changed every time, the restarting frequency is increased by 1, and the restarting period is prolonged once. When the restarting times are not more than the preset times, controlling the computer to automatically restart; and when the restart times are greater than the preset times, controlling the computer to power off. When the restarting mode is changed by prolonging the restarting period, the restarting parameters can be set and modified, and the restarting time is prolonged by 1.3-2.5 times each time.
Furthermore, the restart mode mainly refers to an automatic restart, and certainly, in an embodiment of the present invention, the restart mode further includes a manual restart, and the manual restart signal includes an in-place restart signal or a remote restart signal. Specifically, a manual control key may be provided in the control panel of the device for inputting a local restart signal, and/or a control terminal may be provided on the control panel of the device for receiving a remote restart signal. Manual restart of a computer by receiving a manual restart signal
The voltage abnormal state is a state in which the voltage circuit is abnormal and the voltage is lower than a predetermined value. When the abnormal voltage value is monitored, the computer is powered off and sends an alarm signal to a remote place through a remote transmission channel. When the voltage returns to normal, the power supply is automatically switched on to restart the computer.
For the case of voltage abnormality, it is simple and will not be described too much here. The following describes the processing procedure of current anomaly in the present invention in further detail with reference to specific embodiments, and the processing procedure mainly includes three procedures, namely, a running monitoring procedure, a restarting procedure, and a restarting judgment procedure.

step 303, delaying the system for a certain time T, and modifying the restarting parameters to prolong the restarting process (which can be set to 1.3-2.5 times);
step 304, a first counter + 1;
step 305, judging whether the count is greater than 3 (the number of times of automatic restart is allowed), if so, executing step 306, and if not, executing step 301 again by using the modified restart parameters;
and step 306, controlling the computer to power off and sending an alarm signal.
When the computer is controlled to automatically restart, the number of times of automatic restart of the computer is limited and the automatic restart mode is changed, specifically, first default is to be mechanical restart, the number of times of restart is increased by 1, and whether restart is successful is determined? If the computer is successfully recovered to normal. If the restart fails, the restart period is extended to be changed into power-off restart, the number of restarts is increased by 1, and whether the restart is successful is determined? If the computer is successfully recovered to normal. If the restart fails, extending the restart period again to be changed into mechanical restart, adding 1 to the restart frequency, and determining whether the restart is successful? If the computer is successfully recovered to normal, if the computer is failed, the number of restart times exceeds 3, the power supply of the computer is cut off, and an alarm signal is sent to a remote place through a remote transmission channel.
Referring to fig. 4, the restart judgment process includes the following steps:
step 401, judging whether the current is greater than a first current threshold value M1, if so, entering step 402, if not, ending the judgment process, outputting a restart failure judgment result, and if the shutdown process is greater than the first current threshold value M1 and meets a specified time, indicating that the shutdown process fails;
step 402, clearing and starting a first timer T1;
step 403, the first timer T1 judges that the judgment result is less than the set threshold, the step 404 is entered, if not, the judgment flow is ended, and the judgment result of the restart failure is output;
step 404, judging by a second current threshold M2, if the current is smaller than the set threshold, entering step 405, if the current is not smaller than the set threshold, ending the judgment process, and outputting a restart failure judgment result, where the second current threshold M2 is used to indicate whether an extremely low current point (shutdown) is experienced, and if the current is larger than the set threshold, indicating that no shutdown state exists, and outputting a restart failure result;
step 405, clearing and starting a second timer T2;
step 406, the second timer T2 determines that the current is greater than the set threshold, step 407 is performed, if the current is not greater than the set threshold, the determination process is terminated, and a determination result of the restart failure is output, when the current of the second current threshold M2 continuously rises and stabilizes the high power point (the startup process);

Based on the above, the computer fault recovery method provided by the embodiment of the invention can be used for rapidly starting the restart operation of the computer and monitoring whether the computer is restarted successfully or not to realize fault recovery by monitoring the current and the voltage of the computer when the computer fails due to abnormal current. When the voltage value is abnormal, the power supply is cut off and an alarm is given, and after the voltage is recovered to be normal, the power supply can be automatically switched on and the computer can be restarted. Therefore, the method and the device effectively solve the problem that the operation of the power system is influenced when the system fails, so that the computer can be self-repaired when the system fails, and the continuous operation of computer equipment is ensured.
The first threshold is an upper threshold during normal operation, and if the first threshold is higher than the upper threshold and lasts for a period of time, the computer is considered to be halted (for example, the CPU occupancy rate is 100%, and the system is in a continuous high load), and the second threshold is a lower threshold during normal operation, because the device has basic power consumption once being started, and when the device continues to be between the first threshold and the second threshold, the device can be considered to be operating normally. And (3) starting up control process: in the process of restarting the equipment, the instant moment of shutdown is inevitable, the power consumption of the system at the moment is lower than the second threshold value, and if the condition that the power consumption is lower than the second threshold value is not detected in the process of restarting the equipment, the restarting process is considered to be inevitable to be failed.
