Equipment usage time recording method and device thereof

Abstract

The invention relates to the computer field, and discloses an equipment usage time recording method and a device thereof; the method comprises the following steps: updating data, representing equipment usage time and stored in a first, second and third storage space, according to an updating cycle when the equipment is in a running state; reading three sets of data stored in the storage spaces when the equipment is started; selecting the larger data from the two sets of data as the initial data of the equipment usage time, wherein difference value of the two sets doubles the update cycle, or selecting the largest data from the three sets of the data as the initial data of the equipment usage time; using the selected initial data to update the data in the first, second and third storage spaces. When data is inputted in the storage space, equipment shutdown or sudden power off will cause inputting data errors, thus causing the whole usage time recording failure; the novel method and device can solve said problems, and can effectively record the equipment usage time.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for recording equipment use time. Background technique [0002] In order to be able to conveniently inquire about the number of power on and off and the total usage time of the equipment returned to the factory, a functional module that stores the cumulative number of power on and off and the total usage time of the equipment after power failure is usually installed inside the equipment. However, since the equipment chassis is already highly integrated, adding this functional module will increase the volume of the equipment and the production cost, which has no practical promotion significance. [0003] For this reason, in the prior art, there is an improved way to use the underlying hardware to record the power on and off and the use time, such as adding a general backup power supply device. When the device is powered off, the internal backup power supply is automati...

Problems solved by technology

However, the peripheral circuit used in this method is relatively complicated, and it is necessary to increase the voltage comparison and interrupt output circuit, and also need to increase the large capacitance. Since the capacitance changes with the external environment, the stability is poor. When encountering a relatively harsh environment, such as At the bottom of the winter temperature, the capacity of the capacitor is weakened, which leads to the loss of device data due to failure to write completely
