Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] IoT batteries mainly use lithium-thionyl chloride batteries, which have the characteristics of stable power supply voltage. When the current is constant, the power supply voltage is very stable (such as figure 1 As shown), under the same discharge current, the voltage remains consistent, and the battery power cannot be converted by measuring the voltage. However, in the case of sudden large current, there is a certain voltage drop depending on the current, and this voltage drop has a certain relationship with the battery power; the voltage change is not only related to the current, but also ...

Abstract

The invention is suitable for the technical field of the Internet of Things, and provides an Internet of Things battery electric quantity measurement method, device, system and equipment and a storagemedium, and the method comprises the steps: obtaining the electric quantity parameter information of a to-be-measured Internet of Things battery, and the electric quantity parameter information comprising voltage information, current information, temperature information and continuous working time information; according to the electric quantity parameter information and a preset battery electricquantity measurement model, determining the residual electric quantity of the Internet of Things battery; wherein the preset battery electric quantity measurement model is generated by training a plurality of pre-collected battery discharge samples carrying electric quantity parameter information through a deep learning neural network. According to the method, the electric quantity influence factors are fully considered, the battery electric quantity measurement model established according to the deep neural network and a large amount of sample data is utilized, the accurate battery remainingelectric quantity value can be obtained directly through the battery electric quantity parameters in the using process, and the method can be suitable for a scene with sudden large current.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a battery power measurement method, device, system, equipment and storage medium of the Internet of Things. Background technique [0002] In the use of the Internet of Things, in order to better manage the terminal equipment of the Internet of Things, ensure the stable power supply of the terminal equipment, and ensure the normal operation of the equipment, it is necessary to frequently estimate the remaining power of the battery to avoid running out of power. [0003] The commonly used method for estimating the remaining power is to use the voltage estimation method. For example, if the battery is powered by a rechargeable battery, it can be estimated through the mapping relationship between the voltage and the battery current in the discharge curve of the rechargeable battery, and the current voltage value of the battery can be used to estimate the bat...
