The invention relates to the technical field of communication acquisition, and discloses an intelligent communication acquisition device with power supply control based on STM32, which includes an air conveying plate, a groove is opened on the top surface of the air conveying plate, and an elastic pad A is fixedly connected in the groove, and the elastic pad The top surface of A is fixedly connected with a pedal, and the top surface of the air transmission plate is fixedly connected with a fixed cylinder. Through the setting of the pedal, when the user steps on the pedal when passing through the equipment, the power supply mechanism is automatically activated to supply power to the body temperature detection mechanism, and then in use After the operator leaves the pedal, the body temperature detection mechanism will be automatically powered off, so as to achieve the benefits of saving electricity by starting the body temperature detection mechanism at an appropriate time. In addition, the operation of the device does not require additional power mechanisms and power sources, further saving energy and reducing The benefits of the complexity of the system also avoid the problem that the temperature accumulation caused by the continuous opening of the body temperature detection mechanism affects the service life.

A data capture terminal for, and a method of, automatically capturing data from targets located within a range of working distances from the terminal, employ a controller for automatically controlling a set of focal parameters of an imaging assembly, for storing one of the focal parameters of the imaging assembly upon a successful data capture from a first target, and for automatically selecting a subset of the focal parameters determined from the stored focal parameter to capture data from a second target. The subset is smaller than the set of the focal parameters and corresponds to a restricted zone within the range of working distances to enhance data capture performance of the terminal.
