Embodiment Construction

[0027] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0028] In the absence of a real display device, the present invention provides access to the upper layer Android system through a virtual display device method in the kernel, and when realizing a specific display driver under the framebuffer driver framework of the Linux system, simulates the display device entity by using the memory space The way to meet the access operation of the Android system to the display device, the present invention can solve the problem that the Android system cannot run normally under the condition that the router does not have a display device.

[0029] In a preferred embodiment, the present invention uses a specific memory space as a display device resource by implementing a special display device driver, writes various data parameters of the device into the storage area, and co...

Abstract

The invention relates to a method for realizing virtual display equipment in Android routers. The method comprises the following steps: (1) setting a memory area in an Android router to store related parameters of virtual display equipment; (2) registering the virtual display equipment and a drive of the virtual display equipment in the Android router; and (3) modifying an operation for the virtual display equipment in the drive of the virtual display equipment into an operation for the related parameters, stored in the memory area, of the virtual display equipment. By adopting the method for realizing the virtual display equipment in the Android router, the routers without display equipment also can operate the Android systems, and frame image data can be normally generated on the virtual display equipment, so that the time and power consumption are saved, and expandability is provided to the equipment in the aspect of display.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to network communication equipment, and specifically to a method for realizing a virtual display device in an Android router. Background technique [0002] The network is an indispensable tool for modern people's life, and the gateway device plays a vital role in it. With the development of the Internet of Things, smart homes and smart homes have become the future development direction. As the network manager of all smart devices, the intelligence of gateway devices has become an inevitable trend. In terms of operating systems, the Android system is popular in the mobile terminal equipment market due to its powerful functions, openness, and high customization, and has also become the choice of many non-mobile terminal smart devices. [0003] Due to cost reasons, gateway devices generally do not have display devices, but for smart devices, a convenient operation inter...
