Embodiment 1

[0077] The invention provides a method for calculating the remaining battery power of a measuring instrument, such as figure 1 shown, including the following steps:

[0078] Step S0: dividing battery power level intervals;

[0079] Step S1: Obtain the interval average current, the remaining power when the upper-level power interval is converted to the current-level power interval, and the battery usage time of the current-level power interval;

[0080] Step S2: Obtain the remaining power C1 according to the interval average current, the remaining power when the upper-level power range is converted to the current-level power range, and the battery usage time of the current-level power range;

[0081] Step S3: judging whether the first electric power interval level change occurs according to the remaining electric quantity C1; if the first electric power interval level change occurs, then enter step S4, and if the first electric power interval level change does not occur, then ...

Embodiment 2

[0124] The difference from Embodiment 1 is that the method for calculating the remaining battery capacity of the meter also includes a step of evaluating the remaining battery life, and the step of evaluating the remaining battery life includes: obtaining the remaining power C1 and the average current of the upper-level power range, and according to the remaining power C1 Calculate the remaining service life of the battery by calculating the average current of the upper-level power range. It can be known that the remaining service life of the battery can be obtained by dividing the remaining power C1 by the average current of the upper power range. The remaining service life of the battery can reflect the instrument life of the meter and serve as the basis for the maintenance and replacement of the meter.

Embodiment 3

[0126] The difference from Embodiment 1 is that the method for calculating the remaining battery capacity of the meter also includes the step of evaluating the remaining service life of the battery, and the step of evaluating the remaining service life of the battery includes: obtaining the remaining power C2 and the average current of the upper-level power range, and according to the remaining power C2 and Calculate the average current of the upper power range to get the remaining service life of the battery. It can be known that the remaining service life of the battery can be obtained by dividing the remaining power C2 by the average current in the upper power range. The remaining service life of the battery can reflect the instrument life of the meter and serve as the basis for the maintenance and replacement of the meter.

Abstract

The invention aims to provide a method for calculating residual capacity of a metering instrument battery, thereby settling a technical problem of incapability of realizing low energy consumption andhigh precision in a prior-art solution. The method comprises the following steps of determining whether first capacity interval grade changing occurs according to the residual capacity C1; if yes, obtaining the current battery temperature and the current battery voltage; determining whether second capacity interval grade changing occurs according to the current battery temperature and the currentbattery voltage, and if yes, acquiring the residual capacity C2 according to the current battery temperature and the current battery voltage, and using the residual capacity C2 as the residual capacity in changing from an upper capacity interval to the current capacity interval; and repeating the steps after a preset time interval. The method according to the invention can realizes the following beneficial technical effects: reducing detecting frequency of a residual capacity detecting method, reducing energy consumption and improving precision of the residual capacity of the invention.

Description

technical field [0001] The invention relates to the field of instruments, in particular to a method for calculating the remaining battery power of a meter. Background technique [0002] Lithium primary batteries have the advantages of small size, large capacity, low self-discharge rate, and environmental protection. The rapid development of its application technology has gradually replaced traditional dry batteries and is widely used in metering instruments. With the widespread application of lithium primary batteries, people have put forward higher requirements for the safety and reliability of lithium primary batteries, and their application technical problems have gradually emerged. [0003] On the one hand, due to the long life cycle of lithium primary batteries, some will be applied for more than 5 years. Affected by the use environment, whether the actual service life can meet the design requirements is difficult to prove in the short term. [0004] On the other han...
