Control method and device, cashier system, electronic equipment and computer readable medium

Abstract

The embodiment of the invention discloses a control method and device, a cashier system, electronic equipment and a computer readable medium. The method includes: outputting a first control signal including a plurality of stages; controlling the driving circuit to generate different equivalent voltages through the first control signals of all the stages in sequence, so that an equipment starting component in the driving circuit drives target equipment to be started when the equivalent voltages are matched with the target equipment; and in response to detecting that the target device is turnedon, turning off the first control signal. According to the embodiment, the target equipment can be automatically started under the condition that a user does not know the driving voltage, the drivingtype, the equipment model and other related information of the target equipment, automatic adaptation of the driving voltage and intelligent starting of the equipment are achieved, and the equipment starting convenience is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and specifically relate to a control method, device, cash register system, electronic equipment, and computer-readable media. Background technique [0002] The same electronic device usually needs to be adapted to different driving voltages due to different brands and models. Taking the cash drawer as an example, the driving voltage of the cash drawer is 9V, 12V, 24V, etc., but the cash register terminal (such as cash register, receipt printer) usually can only be adapted to a cash drawer with a single voltage, so when replacing the cash drawer , or when using the cash drawer for the first time, it is necessary to set the drive voltage of the cash drawer in the cash register terminal, or set the cash drawer model, drive type and other information so that the cash drawer terminal can detect the drive voltage of the cash drawer. [0003] However, this method requires ...

Problems solved by technology

[0003] However, this method requires the user to be familiar with the device parameters. If the device parameters are set incorrectly, the driving voltage will be too low to drive the device to turn on or the driving voltage will be too high to affect the service life of the device.

Since the user needs to manually adapt the accurate driving voltage to start the device, it is not convenient to start the device
