Embodiment 1

[0072] image 3 It is a flow chart of the first embodiment of the price tag power control method of the present invention. A price tag power control method, the method comprising:

[0073] S1. Within a preset detection period, the delivery success rate of the uplink signaling of the electronic price tag is obtained through statistics.

[0074] S2. If the delivery success rate is higher than the first preset value, reduce the uplink power of the electronic price tag according to the preset first amplitude in the next detection cycle, if the delivery is successful rate is lower than a second preset value, then increase the uplink power according to a preset second amplitude in the next detection cycle, wherein the first preset value is greater than the second preset value, The first magnitude is less than the second magnitude.

[0075] S3. Repeat the step of reducing or increasing the uplink power until the delivery achievement power in one detection period running with the c...

Embodiment 2

[0088] Figure 4 It is a flow chart of the second embodiment of the price tag power control method of the present invention. Based on the above embodiment, before the statistics of the delivery success rate of the uplink signaling of the electronic price tag are obtained within the preset detection period, it includes:

[0089] S01. When the electronic price tag is powered on, read its built-in uplink power information and power adjustment information.

[0090] S02. Determine the initial uplink power according to the uplink power information, determine the detection start point and cycle duration of the detection cycle according to the power adjustment information, and read the first preset value, The first amplitude, the second preset value, and the second amplitude.

[0091]Optionally, in this embodiment, when the electronic price tag is powered on, its built-in uplink power information and power adjustment information are read, wherein the uplink power information may be p...

Embodiment 3

[0095] Figure 5 It is a flow chart of the third embodiment of the price tag power control method of the present invention. Based on the above embodiment, the statistically obtained delivery success rate of the uplink signaling of the electronic price tag within the preset detection period includes:

[0096] S11. Preset statistics within the detection period.

[0097] S12. When the accumulative delivery times of the uplink signaling reaches the statistical number within the detection period, count the success rate of delivery of the uplink signaling to the corresponding base station.

[0098] Optionally, in this embodiment, according to certain preset conditions, the success rate of delivery of the uplink signaling of the electronic price tag is counted periodically or quantitatively. Wherein, the preset condition may be the detection cycle set in this embodiment, that is, the delivery success rate of the uplink signaling of the electronic price tag is counted within a certai...

Abstract

The invention discloses a price tag power control method and device and a computer readable storage medium, and the method comprises the steps: carrying out the statistics of a delivery success rate of an uplink signal of an electronic price tag in a preset detection period, and if the delivery success rate is higher than a first preset value, reducing the uplink power of the electronic price tag according to a preset first amplitude in the next detection period, if the delivery success rate is lower than a second preset value, increasing the uplink power according to a preset second amplitude in the next detection period, wherein the first preset value is larger than the second preset value, and the first amplitude is smaller than the second amplitude. An efficient price tag power consumption dynamic regulation and control scheme is realized, so that the price tag can regulate and control the current uplink power in a self-adaptive manner, and the price tag power consumption can be effectively reduced while the communication effect is ensured.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method, device and computer-readable storage medium for controlling power of a price tag. Background technique [0002] In the existing technology, with the rise of concepts such as smart retail, smart supermarkets, and unmanned stores, the application of electronic price tags has become increasingly widespread in recent years. People also see electronic price tags in more and more scenes in their daily life. An electronic price tag is a smart terminal device used to display commodity information. It usually consists of control components, communication components, storage components and display components. Electronic price tags usually also require supporting base station equipment. The base station is a management device that can manage multiple price tags at the same time. It stores the information of the managed price tags and the information of the correspond...
