Detailed Description
The technical solutions in the embodiments will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art without any inventive work based on the embodiments belong to the protection scope of the present invention.
Unless otherwise defined, technical or scientific terms used in the embodiments of the present application should have the ordinary meaning as understood by those having ordinary skill in the art. The use of "first," "second," and similar terms in the present embodiments does not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. "mounted," "connected," and "coupled" are to be construed broadly and may, for example, be fixedly coupled, detachably coupled, or integrally coupled; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. "Upper," "lower," "left," "right," "lateral," "vertical," and the like are used solely in relation to the orientation of the components in the figures, and these directional terms are relative terms that are used for descriptive and clarity purposes and that can vary accordingly depending on the orientation in which the components in the figures are placed.
As shown in fig. 1, the infrared thermal imaging image reading apparatus based on the android system in this embodiment includes a controller, where the controller is connected to a USB switching device, and one side of the USB switching device is connected to a USB1, a USB2, and a USB interface; the USB switching device is used for switching the USB1 and the USB2, and the USB1 and the USB2 cannot be opened at the same time and can be opened only by one. The USB switching device comprises a USB switching chip TS3USB221 RSER. The USB1 is connected to the first and second pins of the USB switch chip TS3USB221 RSER. The USB2 is connected to the third and fourth pins of the USB switch chip TS3USB221 RSER. The USB interface is connected to the fifth pin and the sixth pin of the USB switching chip TS3USB221 RSER. One end of the controller is connected to the ninth pin of the USB switching chip TS3USB221RSER through the USB _ SW end, and the USB _ SW end is grounded through a 1k omega resistor.
Two modes of operation: the USB interface is communicated with the USB 1; the USB interface is communicated with the USB 2.
USB interface: and a main USB interface.
USB1, USB 2: and a USB interface is separated.
USB switches the chip: the USB1 and the USB2 are not capable of being opened at the same time but only one, and are responsible for switching the USB1 and the USB 2.
A controller: the USB switching chip is controlled to switch between the USB1 and the USB 2.
