Drawings
The invention is described in detail below with reference to specific embodiments and the attached drawing figures, wherein:
FIG. 1 is a schematic flow chart of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and examples. It should be understood that the following specific examples are only for illustrating the present invention and are not to be construed as limiting the present invention.
As shown in fig. 1, the present invention provides a method for preventing a unit from failing to work after a memory is abnormal, which includes the following steps:
s10: backing up the key parameters in a first storage used for storing the key parameters when the unit runs to at least one second storage in a unit network according to a preset rule;
s20: after the unit is powered on, if the key parameters of the first storage fails to be acquired, calling the key parameters backed up in any one second storage to complete the start of the unit.
Specifically, before the key parameter backup is carried out, the backup rules of the key parameters are preset, when the unit runs and any one of the preset rules appears, the key parameters are backed up, and by adopting the mode, the situation that the system resources of the unit are excessively occupied due to unnecessary repeated backup is avoided while the normal backup of the key parameters is ensured.
The specific backup process is as follows: when any one of the preset rules appears during the running of the unit, the control unit in charge of the key parameter backup starts the key parameter backup, backups the key parameters in the first storage in which the key parameters are stored to at least one second storage in the unit network, and completes the backup of the key parameters. If any rule in the preset rules does not appear during the operation of the unit, the control unit responsible for the backup of the key parameters does not perform backup operation on the key parameters in the first storage, so that the consumption of system resources is reduced.
After the unit is powered on, the control unit responsible for key parameter backup firstly calls the key parameters stored in the first memory, and if the calling of the key parameters in the first memory fails, the control unit continuously calls the key parameters backed up in any one of the second memories to complete the starting of the unit. The starting of the unit is completed by acquiring the key parameters backed up in the second memory under the condition that the first memory is abnormal, so that the problem that the first memory cannot work when the first memory is abnormal due to the erasing service life of the first memory or the severe installation environment is solved. The experience degree of the user on the product is improved.
By adopting the technical scheme, the key parameters of the unit are backed up through the preset backup rule, when the unit cannot be started due to the loss of the key parameters in the first storage, the unit is started by calling the backed-up key parameters, the problem that the unit cannot work due to the abnormity of the first storage is solved, the maintenance cost of the unit is reduced, and the product experience of a user is improved.
In an embodiment of the present application, the backing up the key parameter according to a preset rule includes: and when the unit is powered on for the first time, backing up the key parameters in the first storage, and/or when the key parameters change, backing up the key parameters in the first storage.
Specifically, when the unit is powered on for the first time, installation and debugging personnel can debug the unit equipment, and the debugging process comprises inputting a power-on password of the unit, setting related operation parameters and the like. After the steps are completed, the key parameters in the first storage used for storing the key parameters in the unit are immediately backed up, and the problem that the key parameter calling fails due to the backup delay is avoided. And/or when the key parameters change, backing up the key parameters in the first storage to ensure that the backed-up key parameters are always in the latest state, thereby ensuring the validity of the key parameters.

When the capacity of the device is less than or equal to the capacity required to be occupied by the key parameter, the device is judged not to meet the condition for storing the key parameter, namely the device cannot store the key parameter, and the device does not have any action and does not feed back any information at the same time.
By adopting the technical scheme, the equipment in the unit network calculates the storage capacity of the equipment after receiving the broadcast information sent by the control unit responsible for storing the key parameters, and only when the storage capacity of the equipment is larger than the capacity occupied by the key parameters, the key parameters are stored, so that the integrity of the backed-up key parameters is ensured.
