Detailed Description
The core of the invention is to provide a dual-system device, on one hand, different functions corresponding to two processors can be completed, and data interaction can be carried out between a first processor and a second processor, so that the use range is enlarged, and the functions which can be realized are increased; on the other hand, the two processors are powered by two different power supply modules, when one power supply module is out of power, the other power supply module and the corresponding processor can continue to work, and the use by a user is facilitated.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a dual-system device provided in the present invention, including:
the first power supply module 1 is connected with the first processor 3 and used for supplying power to the first processor 3;
the second power supply module 2 is connected with the second processor 4 and is used for supplying power to the second processor 4;
the first processor 3, which is connected with the second processor 4 and is different from the second processor 4, is used for receiving a second instruction, executing an operation corresponding to the second instruction and sending a first instruction to the second processor 4;
the second processor 4 is configured to receive the first instruction, execute an operation corresponding to the first instruction, and send the second instruction to the first processor 3.
Considering that when only one processor is provided, the intelligent terminal where the processor is located has fewer functions, and when the power supply module of the processor is out of power, the intelligent terminal cannot work, the use of the user is affected,
in order to solve the above problems, the present application provides two power modules and two processors, where the first power module 1 supplies power to the first processor 3, the second power module 2 supplies power to the second processor 4, and the first processor 3 and the second processor 4 may perform data interaction, that is, the first processor 3 may send a first instruction to the second processor 4, the second processor 4 executes an operation corresponding to the first instruction, the second processor 4 may send a second instruction to the first processor 3, and the first processor 3 executes an operation corresponding to the second instruction. In addition, the first processor 3 and the second processor 4 have different functions, so that the use range is enlarged, the functions which can be realized are increased, and the first processor and the second processor are respectively supplied with power by different power supply modules, so that the cruising ability of the dual-system device is improved.
Specifically, assuming that the first processor 3 can implement the first type of function, the second processor 4 can implement the second type of function, the first processor 3 is powered by the first power module 1, and the second processor 4 is powered by the second power module 2, when both the first power module 1 and the second power module 2 are powered, the apparatus can implement the first type of function and the second type of function. If the energy consumption of the function that can be realized by the first processor 3 is large and the energy consumption of the function that can be realized by the second processor 4 is small, when the first power module 1 is not powered (i.e., the first processor 3 does not work) and the second power module 2 is powered, the first type of function cannot be realized, but the second processor 4 can still realize the second type of function. In practice, some basic functions may be provided in the second processor 4, so that when the first power supply module 1 is dead, a user can use the device to implement some basic functions.
The intelligent terminal with dual systems includes: smart watches, smart school badges, watch cards, electronic student certificates, etc., hereinafter, description will be given taking a smart school badge with a dual system as an example. The first processor 3 is assumed to be a processor based on an android operating system and has the functions of video call, voice call, online watching and learning video, electronic map and the like; the second processor 4 is assumed to be a single-chip processor and has the functions of card-swiping consumption, sign-in, online answering and the like. When the first power supply module 1 and the second power supply module 2 are powered on, the intelligent school sign can complete all functions of a processor based on an android operating system and a single chip processor; however, because the processor based on the android operating system has relatively large energy consumption, when the processor based on the android operating system does not work (namely, the first power module 1 is out of power), the single chip processor can still execute the corresponding function of the single chip processor, so that a series of basic functions of card swiping consumption, class attendance or online answering and the like of students in schools can be realized, and the teaching arrangement is prevented from being influenced.
In summary, the dual-system apparatus provided in the present application, on one hand, can complete different functions corresponding to the two processors, and the first processor 3 and the second processor 4 can perform data interaction, thereby increasing the application range and increasing the functions that can be realized; on the other hand, the two processors are powered by two different power supply modules, when one power supply module is out of power, the other power supply module and the corresponding processor can continue to work, and the use by a user is facilitated.
