Problems solved by technology

[0003] The timely response and reasonable problem solving of retail cabinets in abnormal situations are particularly important. At present, after the equipment is powered off, the backup battery supplies power to the main equipment. Finally, the backup battery is exhausted and there is no power-off reminder, which increases the terminal shoppers’ stress. The risk of loss caused by abnormal orders brought about by long-term shopping

Embodiment 1

[0071] Such as figure 1 As shown, the present embodiment provides a method for prompting a power failure of a retail device. The retail device includes a backup battery. Based on the power failure of the retail device, the backup battery is started. The power failure prompt method includes the following steps:

[0072] Step S102, outputting prompt information based on the voltage of the backup battery being less than or equal to the first voltage threshold.

[0073] In this embodiment, the retail device is provided with a backup battery. When the retail device is normally powered by an external power supply of 220V, the backup battery does not work. The device supplies power, for example, the main device Android board, MCU (Microcontroller Unit, also known as single-chip microcomputer) board, speaker, camera, door lock sensor and so on.

[0074] In this embodiment, because the backup battery continuously supplies power to the equipment in the retail device, the voltage of the...

Embodiment 2

[0076] Such as figure 2 As shown, this embodiment provides a power-off reminder method for a retail device. In addition to the technical features of the above-mentioned embodiments, this embodiment further includes the following technical features:

[0077] Before outputting the prompt message based on the voltage of the backup battery being less than or equal to the first voltage threshold, the following steps are further included:

[0078] Step S202, monitoring the voltage of the backup battery.

[0079] In this embodiment, when the retail device is normally powered by the external power supply, the backup battery does not work. When the external power supply is disconnected and the retail device is powered off, the backup battery starts to supply power for the equipment in the retail device, because the backup battery is constantly Supply power to the equipment in the retail device, so the voltage of the backup battery will decrease. By monitoring the voltage of the backu...

Embodiment 3

[0082] Such as image 3 As shown, this embodiment provides a power-off reminder method for a retail device. In addition to the technical features of the above-mentioned embodiments, this embodiment further includes the following technical features:

[0083] The retail device also includes a loudspeaker, and the power failure prompting method also includes the following steps:

[0084] Step S302, based on the voltage of the backup battery being less than or equal to the first voltage threshold, turn on the speaker.

[0085] In this embodiment, when the retail device is powered off, the backup battery starts to supply power to the equipment in the retail device, and the voltage of the backup battery is monitored in real time. When the voltage of the backup battery is less than or equal to the first voltage threshold, the voltage drops When the first voltage threshold is reached, the speaker of the retail device is turned on.

[0086] In this embodiment, when the voltage of the...

Abstract

The invention provides a power failure prompting method and device, a retail device and a readable storage medium. The power failure prompting method comprises the step of outputting prompting information based on the fact that the voltage of the standby battery is smaller than or equal to a first voltage threshold. According to the technical scheme, when the voltage of the standby battery is smaller than or equal to the first voltage threshold value, the prompt information is output, an abnormal order of the retail device can be effectively avoided, the loss of consumers is reduced, and the consumption experience of the consumers is improved.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular, relates to a power-off prompting method and device, a retail device, and a readable storage medium. Background technique [0002] An epidemic has made the contactless unmanned vending model accepted by more and more people. Statistics show that smart retail terminals are more attractive than ordinary offline sales, and the number of goods sold has increased significantly. For investors, the use of smart retail terminals can replace manpower and reduce overall cost consumption, so it has become a very promising retail method. [0003] The timely response and reasonable problem solving of retail cabinets in abnormal situations are particularly important. At present, after the equipment is powered off, the backup battery supplies power to the main equipment. Finally, the backup battery is exhausted and there is no power-off reminder, which increases the terminal shop...
