Method and system for predicting remaining power of electronic lock

Abstract

The invention discloses a method and system for predicting the remaining power of an electronic lock. The system comprises a data acquisition module, an execution time calculation module, a current battery remaining power calculation module and a battery capacity comparison module which are sequentially connected. The method and system for predicting the remaining power of an electronic lock, obtain the current value of each power-consuming module and calculate the respective execution time of the power-consuming module so as to calculate the current remaining capacity of the battery, comparethe current remaining capacity with the normal capacity of the battery so as to clearly obtain the ratio of the remaining battery capacity, and give an alarm when the ratio is lower than a first preset alarm threshold. The method and system do not require a large amount of test data and can obtain the remaining battery power by using four current values and four execution times, and the method issimple and effective.

Description

technical field [0001] The invention relates to the field of electronic locks, in particular to a system and method for predicting the remaining power of an electronic lock. Background technique [0002] The lock manufacturing industry is one of the important industries of the national economy. The lock has a huge market capacity and increasing demand year by year, which drives the rapid development of the lock industry. In the past, mechanical locks needed a key to open, and if you forgot to bring the key, you would be "rejected". [0003] With the development of science and technology, electronic locks can bring users a more convenient way to open the door. However, the cost of electronic locks currently on the market is relatively high, and they are not used in many occasions, such as drawers, cabinets and other occasions that do not require high security levels. Moreover, at present, many electronic locks do not have the service life prediction and reminder function. O...

Problems solved by technology

However, the cost of electronic locks currently on the market is relatively high, and they are not used in many occasions, such as drawers, cabinets and other occasions that do not require high security levels.

Moreover, at present, many electronic locks do not have the service life prediction reminder function. Once the power is out, it will cause the trouble of not being able to open the lock.

Secondly, the use of high-end power management chips and power prediction technology will increase the cost of electronic locks, which is not conducive to the general consumer demand of the public
