Description

Method, device and equipment for prolonging service life of battery of low-power-consumption Internet of things equipment

Technical Field

The invention belongs to the technical field of Internet of things, and particularly relates to a method and a device for prolonging the service life of a battery of low-power-consumption Internet of things equipment, the low-power-consumption Internet of things equipment and a computer-readable storage medium.

Background

With the continuous development and progress of the technology of the internet of things, the application of the technology of the internet of things is more and more extensive.

At present, when the low-power consumption internet of things equipment is used, most of the low-power consumption internet of things equipment is in a dormant state, namely a low-power consumption state, so that the power consumption is reduced as much as possible, and the service life of a battery of the equipment is prolonged. When the low-power-consumption Internet of things equipment is used, the low-power-consumption Internet of things equipment needs to be awakened periodically to communicate with the gateway, so that the equipment needs to realize a timing function during dormancy so as to be awakened to work within a specified period of time. The wakeup period can be specifically set by the gateway, the set period time is in hours, and the maximum timing time of the timer of the low-power consumption internet of things device is 255 seconds each time, so that the software of the low-power consumption internet of things device needs to realize an accumulated timing function, for example, when the wakeup period time is 5 minutes, the software needs to count up 1 time 255 seconds and 1 time 45 seconds to meet the timing requirement of 5 minutes.

When the time is 255 seconds, the low-power-consumption Internet of things equipment is awakened from the sleep state, the remaining time is calculated, the remaining time is set in the timer for timing again, and then the Internet of things equipment enters the sleep state. The re-timing of this wake-up is relatively power consuming and takes a certain amount of time. However, the process of calculating the remaining time in the current wake-up state generally includes hardware initialization, software initialization, and judging whether the wake-up is slow 255 seconds during the software initialization, and if so, calculating the remaining time, setting a timer, and then entering into sleep. Thus, the calculation time for calculating the remaining timing during the sleep period is slightly longer, the longer the time is, the more the consumed electric power is, the faster the battery product consumes, and the service life is short.

Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

In order to explain the technical means of the present invention, the following description will be given by way of specific examples.

Example one

The technical scheme provided by the embodiment of the invention is particularly applied to low-power-consumption wireless Internet of things sensor equipment, and the equipment can support one or more of wireless protocols such as WIFI, Zigbee, NB-loT, eMTC, Z-wave, LoRa, SigFox, RF (radio frequency) and Bluetooth. The low-power-consumption wireless equipment can be specifically installed on the intelligent door and used for detecting whether a person approaches the intelligent door; of course, the method may also be specifically applied to other application scenarios, and is not limited herein.

The technical solutions provided by the embodiments of the present invention are described in detail below.

Referring to fig. 1, a schematic flow chart of a method for prolonging a service life of a battery of a low-power consumption internet of things device provided in an embodiment of the present invention is shown, where the method includes the following steps:

step S101, receiving a timing wake-up signal, and entering a wake-up state according to the timing wake-up signal.

And step S102, hardware initialization is carried out, and whether the timing wake-up signal is a 255-second timing wake-up signal or not is judged in the hardware initialization stage.

It can be understood that, the hardware initialization stage determines whether the reason for the timed wakeup is the timed wakeup of 255 seconds, and if so, the hardware initialization stage enters the sleep state after quickly calculating the remaining time. According to the technical scheme provided by the embodiment of the invention, when the awakening reason is 255 seconds, the battery can enter the dormant state without software initialization, so that the time consumption is short, and the service life of the battery is prolonged.

And step S103, when the timing wake-up signal is the 255-second timing wake-up signal, calculating the remaining timing time according to the preset timing time, setting the timing time of the timer according to the remaining timing time, and then entering a sleep state.

Specifically, when the reason for timed awakening is determined to be 255 seconds of timed awakening, the remaining time is calculated according to the preset cycle time and awakening times, and then the timed awakening time of the timer is set based on the calculated remaining time, and then the timer enters the sleep state.

For example, the preset time is 5 minutes, and when the device wakes up with 255 seconds after the timer expires, the device subtracts the time between 5 minutes and 255 seconds to calculate the remaining time to be 45 seconds, and then enters the sleep state after setting the remaining time of the timer to be 45 seconds.

When the reason for timing awakening is judged not to be awakening after 255 seconds of timing awakening, software initialization can be carried out to enter a sleep state.

Optionally, after the hardware initialization is performed and it is determined in the hardware initialization stage whether the timed wake-up signal is a 255 second timed wake-up signal, the method further includes:

and step S104, when the timing wake-up signal is not the 255-second timing wake-up signal, performing software initialization, and entering a sleep state after the software initialization.

Before entering the hibernation state, it may be determined whether the current conditions of the device satisfy the conditions for entering the hibernation state, and if so, hibernation. Therefore, in some embodiments of the present invention, after the performing the software initialization, the method may further include: judging whether the current condition meets the condition of entering a dormant state or not; when the current condition meets the condition of entering the dormant state, executing the step of entering the dormant state; and when the current condition does not meet the condition of entering the dormant state, continuing to execute the software initialization operation.

It will be appreciated that if the software initialization operation of the current device has been completed, the entry into the sleep state is eligible, and conversely, if not, the entry into the sleep state is ineligible.

In this embodiment, it is determined whether the current wake-up reason is wake-up for 255 seconds at the hardware initialization stage, and if so, the remaining time is calculated, the remaining time of the device timer is reset, and then the device timer enters the sleep state. Therefore, the sleep state can be quickly entered without a software initialization stage in the prior art, the work of the equipment initialization stage is reduced, the consumed time is short, the power consumption is low, and the service life of the battery is prolonged.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
