Power supply control system and method, printing equipment and power supply control method thereof

Abstract

The invention discloses a power supply control system and method, printing equipment and a power supply control method thereof. The printing equipment comprises a first power supply circuit, a power module, a power management circuit, a main control circuit and a printing module. The first power supply circuit is connected with an external power supply module and supplies power to electric parts of the printing equipment; when the printing equipment is in a printing working mode, the power supply module serves as a second power supply circuit and supplies power to the power supply management circuit together with the first power supply circuit; and when the printing equipment is in a non-printing working mode, the power supply management circuit controls the first power supply circuit to charge the power supply module. According to the invention, the requirement of electric equipment such as a printer for high-peak current in a set working state can be met through a convenient interface, and a power adapter does not need to be configured. The cost of the whole machine is reduced, authentication of an adapter is not needed, the authentication cost is reduced, and installation and wiring are simplified.

Description

technical field [0001] The invention belongs to the technical field of printing equipment and relates to a printing equipment, in particular to a power supply control system and method, a printing equipment and a power supply control method thereof. Background technique [0002] At present, the 58mm and 80mm thermal printers currently on the market, due to the large power consumption during the printing process, are generally powered by the power adapter, which can provide a large peak current to ensure the stability of the printing process and the motor paper. sex. However, the cost of this solution is high, and the authentication requirements of the machine with the adapter are also higher. Moreover, since the power adapter and power cord are hung behind the machine, it will bring certain potential safety hazards, and the wiring is also messy. [0003] In view of this, there is an urgent need to design a new printer device in order to overcome at least some of the above-m...
