Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application belongs. The use of the terms "comprising" or "including" in the description and claims of this application is intended to indicate that an element or item listed before "comprising" or "includes" and its equivalents are covered by the element or item listed after "comprising" or "including," and does not exclude other elements or items.

It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
Fig. 1 is a block diagram of an electronic device according to the present application. The electronic device 10 comprises a processor 11 and an input means 12. In some embodiments, the processor 11 runs a first operating system and a second operating system, and the first operating system and the second operating system are different from each other, for example, the first operating system is a system with low real-time requirement, and the second operating system is a system with high real-time requirement. Or the first operating system has higher requirements on usability and user experience, and the second operating system has lower requirements on usability and user experience, and the like. In some embodiments, the first operating system and the second operating system provide a runtime environment for a foreground program and a background program, respectively.
An input device 12 is connected to the processor 11, the input device 12 having a plurality of keys for inputting key information. In some embodiments, the electronic device 10 is a teach pendant of a robotic control system, and the input device 12 is a physical key panel on the teach pendant, which may have tens of keys. The physical key panel is connected with the processor in an external mode through a peripheral circuit. In the application, the two operating systems share the input device, specifically, when the user presses a key, the key information is sent to the processor, and the first operating system and the second operating system receive the key information at the same time. The first operating system judges whether the key information contains first key information, if so, a first operation corresponding to the first key information is executed, the second operating system judges whether the key information contains second key information, and if so, a second operation corresponding to the second key information is executed.
In some embodiments, the electronic device includes a driver module that is responsible for converting the key information into keyboard input information for the first operating system. Namely, the driving module converts the key information into the keyboard input information of the external keyboard equipment of the first operating system, so that each application program under the first operating system can execute corresponding operation. Specifically, the electronic device further includes a configuration module, where the configuration module is responsible for configuring keyboard symbols corresponding to the keys of the input device, and for example, the physical keys of the input device may be dynamically mapped to the keyboard key combination information of the first operating system through a key character mapping table. The configuration module may configure the physical buttons as individual keyboard character information, but may also be configured as composite keyboard character information such as: ctrl + F1. Taking an example of an input device having 20 keys, the following key character mapping is designed.
The first operating system executes corresponding first operation based on the keyboard input information. For example, when the key No. 9 of the input device is pressed, the driving module maps it to "Ctrl + F9" keyboard information, and the first operating system performs a "LOCK SCREEN" LOCK operation based on the keyboard information.
In some embodiments, the first operating system is an Android system and the second operating system is a Linux system. In some embodiments, the Android system and the Linux system each have a file system to prevent interference conflicts.
In some embodiments, the Linux system includes a device file into which the key information of the input device can be written. And the second operating system reads the equipment file and executes a second operation when identifying that the data stream corresponding to the second key information is contained in the equipment file.
Specifically, the device file exists in a file system under the Linux system, but does not work under the Android system. Therefore, when the user presses the physical key corresponding to the second key information, the Android system receives key information similar to that of the common keyboard, and the data stream is written into the equipment file of the Linux system. In some embodiments, the key information is written into the device file in the form of a bitstream, each bit of the bitstream representing a pressed state of a corresponding key press or release. For example, when a bit of 1 indicates that the corresponding key is pressed, a bit of 0 indicates that the corresponding key is released. Of course, in other embodiments, 0 may represent the pressed state and 1 may represent the released state, and the application is not limited thereto. For the Linux system, the mode of using the device file is more convenient for background programs to use. The device file can be read when needed by the daemon. Preferably, the Linux system continuously reads the device file corresponding to the input device in real time, and obtains the latest key state data stream therefrom.
For example, 32 bits of data can be obtained for each reading by the Linux system, and each bit corresponds to one key state. For example, if the 3 rd bit is 1, it means that the 3 rd key (RUN) is pressed, and if it is 0, it means that the corresponding key is not pressed.
Some keys of the input device may represent robot movement commands. For example, keys 11-20 are motion keys for controlling the motion of the robot. Under this setting, bits 11-20 of the data stream correspond to key information of key No. 11-20. When the 11 th-20 th bit is data with 1, the data indicates that a corresponding action key is pressed, and the Linux system can immediately inform the operation and control action process to control the robot to execute corresponding movement. Such as: when the value of the 11 th bit is found to be 1, indicating that the first axis of the robot needs to move clockwise; a value of 1 for bit 14 indicates that the second axis of the robot needs to move counter-clockwise. The keys and corresponding commands of the input device can be preset according to requirements.
In some embodiments, the real-time performance of the first operation executed by the Android system is low, and the real-time performance of the second operation executed by the Linux system is high. For example, in some embodiments, the first operation is a user interface operation (e.g., a lock screen operation) and the second operation is a robot motion control operation.
In some embodiments, since the processor runs both operating systems simultaneously, in order to ensure exclusivity of the output device (e.g., display), only the user interface of the first operating system is reserved, while the user interface of the second operating system is removed.
The key information and the corresponding first operating system and second operating system instructions can be set according to requirements. In some embodiments, the first key information and the second key information are completely different, for example, keys No. 1-10 of the input device are the first key information and correspond to a user interface operation of an Android system; the No. 11-20 key is second key information and corresponds to the operation control operation of the robot of the Linux system. In some embodiments, the first key information may also at least partially overlap with the second key information, for example, the number 9 key of the input device may be used as both the first key information and the second key information, and may correspond to a user interface operation of the Android system, such as a screen locking operation, and may also correspond to a robot motion control operation of the Linux system, such as a shaft rotation operation.
According to the method, the double-operating-system and key sharing mechanism is realized on the electronic equipment, when a user presses a certain key of the input device, the Android system and the Linux system can receive and process key information respectively without mutual interference, so that the motion control operation can be directly processed in the background process of the Linux system, and the user interface operations such as screen locking and the like can be executed without winding around the background by directly monitoring the keyboard information in the UI (user interface) program of the foreground Android system, and therefore both the real-time performance and the UI experience of the system are considered.
FIG. 2 is a flow chart illustrating steps of one embodiment of a method of operating an electronic device of the present application.
The operation method of the electronic equipment comprises the following steps:
s1, running a first operating system and a second operating system on the processor;
s2, the first operating system and the second operating system simultaneously receive the key information from the input device;
s3, determining whether the key information includes the first key information, if yes, executing step S4; and determining whether the key information includes second key information, if yes, executing step S5;
s4, the first operation system executes the first operation corresponding to the first key information;
s5, the second operating system performs a second operation corresponding to the second key information.
In some embodiments, the step of the first operating system performing the first operation corresponding to the first key information at step S4 further includes:
s41, converting the first key information into first keyboard input information;
and S42, executing corresponding first operation based on the first keyboard input information.
Specifically, the physical keys of the input device can be dynamically mapped to the keyboard key combination information of the first operating system through the key character mapping table. For example, the 9-number key is mapped to "Ctrl + F9" keyboard information. Then when the key No. 9 of the input device is pressed, the driving module maps it to the "Ctrl + F9" keyboard information, based on which the first operating system performs the "LOCK SCREEN" LOCK operation.
In some embodiments, the first operating system is an Android system and the second operating system is a Linux system. The step of determining whether the key information includes the second key information in step S3 further includes:
s31, writing the key information into the equipment file of the Linux system;
s32, identifying whether the device file contains the data stream corresponding to the second key information, if yes, executing step S5.
Specifically, the Linux system includes a device file into which key information of the input apparatus can be written. And the second operating system reads the equipment file and executes a second operation when identifying that the data stream corresponding to the second key information is contained in the equipment file. Since the device file exists in the file system under the Linux system, but does not work under the Android system, when the user presses the physical key corresponding to the second key information, the Android system receives key information similar to a common keyboard, and the data stream is written into the device file of the Linux system.
In some embodiments, the key information is written into the device file in S32 in a bitstream, where each bit of the bitstream represents a pressed state of the corresponding key. For example, when a bit of 1 indicates that the corresponding key is pressed, a bit of 0 indicates that the corresponding key is released. Of course, in other embodiments, 0 may represent the pressed state and 1 may represent the released state, and the application is not limited thereto. For the Linux system, the mode of using the device file is more convenient for background programs to use. The device file can be read when needed by the daemon. Preferably, the Linux system continuously reads the device file corresponding to the input device in real time, and obtains the latest key state data stream therefrom.
For example, 32 bits of data can be obtained for each reading by the Linux system, and each bit corresponds to one key state. For example, if the 3 rd bit is 1, it means that the 3 rd key (RUN) is pressed, and if it is 0, it means that the corresponding key is not pressed.
Some keys of the input device may represent robot movement commands. For example, keys 11-20 are motion keys for controlling the motion of the robot. Under this setting, bits 11-20 of the data stream correspond to key information of key No. 11-20. When the 11 th-20 th bit is data with 1, the data indicates that a corresponding action key is pressed, and the Linux system can immediately inform the operation and control action process to control the robot to execute corresponding movement. Such as: when the value of the 11 th bit is found to be 1, indicating that the first axis of the robot needs to move clockwise (Joint 1 +); a value of 1 for bit 14 indicates that the second axis of the robot needs to move counter-clockwise (Joint 2-). The keys and corresponding commands of the input device can be preset according to requirements.
In some embodiments, the real-time performance of the first operation executed by the Android system is low, and the real-time performance of the second operation executed by the Linux system is high. For example, in some embodiments, the first operation is a user interface operation (e.g., a lock screen operation) and the second operation is a robot motion control operation.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
