Description

INFORMATION DISPLAYING METHOD, DEVICE, AND SYSTEM BACKGROUND Technical Field
The present invention relates to the field of information processing technologies, and in particular, to an information displaying method, device, and system.
Related Art
With rapid development of the information age, people increasingly depend on various visualized devices to obtain information. Usually, related information of a system is displayed on a user interface presented by a device, so as to facilitate a user to perform determining and operations on an operating status of the system according to the obtained information.
An industrial system is used as an example below. Usually, at least one controlling room (controlling room) may exist in an industry, and is used for monitoring operating of the industrial system. Usually, multiple monitors are disposed in the controlling room, and different monitors achieve different functions. For one of the monitors, usually, various information may need to be displayed on the monitor. The information includes but is not limited to: a data curve used for monitoring a tendency of a parameter value, device status information, diagnosis information, and the like.
FIG. 1 shows a user interface of a monitor in a controlling room in an electric power plant (used as an example of an industrial system) . The user interface is used for monitoring an operating status of a steam turbine in the electric power plant, and shows main information such as elements of the steam turbine, and temperatures and pressures of some elements. A user may learn a whole operating status of the steam turbine by observing the main information of this part. In addition, the user interface also shows assistance information such as a data curve 101, device status information 102, an element logic diagram 103, and guidance information 104, for assisting determining the operating status of the steam turbine.
At present, when an operator performs monitoring, the operator may move the assistance information to an edge or a blank area of the user interface, to not affect observation of the whole operating status of the steam turbine. However, the assistance information may still occupy a particular part of the user interface, and may cause displaying incompleteness of the main information on the user interface.
SUMMARY
The present invention provides an information displaying method, device, and system, so that a user can clearly and completely view various information on a user interface.
According to a first aspect, an information displaying system is provided. The information displaying system is configured to display related information of a system (for example, an industrial system) .
The information displaying system may include a main device and at least one auxiliary device.
The main device displays, on a user interface of the main device, at least one component of the system and related information of a first part in the at least one component； detects a first input operation on the user interface of the main device, where the first input operation is used for instructing to display the related information of the first part on a first auxiliary device of the at least one auxiliary device； and after the first input operation is detected, stops displaying the related information of the first part on the user interface of the main device, and sends the related information of the first part to the first auxiliary device.
The first auxiliary device receives the related information of the first part from the main device, and displays the related information of the first part on a user interface of the first auxiliary device.
According to a second aspect, an information displaying method is provided. The method may be performed by the information displaying system provided in the first aspect.
In the first aspect and the second aspect, part of information is transferred to a user  interface of an auxiliary device for displaying, so that information displaying of a main device is not affected, and the information of a system is displayed more clearly and more complete.
With reference to the information displaying system provided in the first aspect and/or the information displaying method provided in the second aspect, in a possible implementation manner,
after sending the related information of the first part to the first auxiliary device, the main device sends the updated related information of the first part to the first auxiliary device； the first auxiliary device receives the updated related information of the first part from the main device, and displays the updated related information of the first part on the user interface of the first auxiliary device.
In this way, the related information of the first part displayed on the first auxiliary device may be updated in real time, and a user may view the related information of the first part on the first auxiliary device in real time.
With reference to any aspect or any possible implementation manner, in a possible implementation manner,
after displaying the related information of the first part on the user interface of the first auxiliary device, the first auxiliary device detects a second input operation on the user interface of the first auxiliary device, where the second input operation is used for instructing to display the related information of the first part on the main device； after the second input operation is detected, the first auxiliary device stops displaying the related information of the first part on the user interface of the first auxiliary device, and sends a first instruction message to the main device, where the first instruction message is used for instructing the main device to re-display the related information of the first part on the user interface of the main device； after receiving the first instruction message from the first auxiliary device, the main device re-displays the related information of the first part on the user interface of the main device.
In this way, a user may perform an operation on the first auxiliary device. The related  information of the first part is re-displayed on the main device, and a displaying manner is more flexible. For example, when the user no longer focuses on the related information of the first part but focuses on related information of another part, the related information of the another part may be displayed on the user interface of the first auxiliary device, so that displayed information of the first auxiliary device is adjusted.
With reference to any aspect or any possible implementation manner, in a possible implementation manner,
after displaying the related information of the first part on the user interface of the first auxiliary device, the first auxiliary device detects a third input operation on the user interface of the first auxiliary device, where the third input operation is used for instructing to display the related information of the first part on a second auxiliary device； after the third input operation is detected, the first auxiliary device stops displaying the related information of the first part on the user interface of the first auxiliary device, and sends a second instruction message to the main device, where the second instruction message is used for instructing the main device to display the related information of the first part on a user interface of the second auxiliary device； after receiving the second instruction message, the main device stops sending the related information of the first part to the first auxiliary device, and sends the related information of the first part to the second auxiliary device； the second auxiliary device displays the received related information of the first part on the user interface of the second auxiliary device.
In this way, the related information of the first part may be switched to display on different devices. A user may choose a suitable device according to different information, and an operation is more flexible.
With reference to any aspect or any possible implementation manner, when the main device detects the first input operation, multiple optional implementation manners may be as follows:
the main device detects the following operations inputted by a user: choosing the related information of the first part on the user interface of the main device, and dragging  the chosen related information of the first part at a speed faster than a preset first speed； or
the main device detects the following operations inputted by a user: choosing the related information of the first part on the user interface of the main device, dragging the chosen related information of the first part at a speed faster than a preset first speed, and choosing the first auxiliary device in a device list that is on the user interface of the main device, where the device list is expanded in response to the input operation of dragging the chosen related information of the first part at a speed faster than a preset first speed； or
the main device detects the following operations inputted by a user: choosing the related information of the first part on the user interface of the main device, and moving the chosen related information of the first part to a first icon displayed on the user interface of the main device； or
the main device detects the following operations inputted by a user: choosing the related information of the first part on the user interface of the main device, moving the chosen related information of the first part to a first icon displayed on the user interface of the main device, and choosing the first auxiliary device in a device list that is on the user interface of the main device, where the device list is expanded in response to the operation of moving the chosen related information of the first part to a first icon.
For the former two input detection manners, a user may perform an displaying switching operation conveniently and simply. The user merely needs to choose information to be operated and quickly drag the information to be operated.
For the latter two input detection manners, the intention of a displaying switching operation of a user may be accurately recognized by using a first icon, so as to implement displaying switching accurately.
For the second and the fourth input detection manners, an auxiliary device may be chosen, and a user may choose a suitable auxiliary device according to different information, so that implementation is more flexible, and the user experience is better.
For the latter two input detection manners, the main device may display the first icon outside a display area of the at least one component on the user interface of the main  device.
In this way, displaying of the first icon may not affect displaying of other information on the user interface of the main device.
Similarly, when the first auxiliary device detects the second input operation, multiple optional implementation manners may be as follows:
the first auxiliary device may detect the following operations inputted by a user: choosing the related information of the first part on the user interface of the first auxiliary device, and dragging the related information of the first part at a speed faster than a preset second speed； or
the first auxiliary device may detect the following operations inputted by a user: choosing the related information of the first part on the user interface of the first auxiliary device, and moving the chosen related information of the first part to a third icon displayed on the user interface of the first auxiliary device.
For the latter input detection manner, the first auxiliary device may display the third icon outside a display area of the related information of the first part on the user interface of the first auxiliary device. In this way, displaying of the third icon may not affect displaying of other information on the user interface of the main device.
According to a third aspect, an embodiment of the present invention provides an information displaying device. The information displaying device is configured to display related information of a system. The information displaying device may be the main device or the auxiliary device provided in the first aspect or the second aspect, and may include: an information displaying module, configured to implement the information displaying； an input operation detection module, configured to implement the input operation detection； and an information transceiver module, configured to implement the information receiving and transmitting.
According to a fourth aspect, an embodiment of the present invention provides an information displaying device. The information displaying device is configured to display related information of a system. The information displaying device may be the main device  or the auxiliary device provided in the first aspect or the second aspect, and may include: at least one processor； and at least one memory, coupled to the at least one processor, and storing a machine instruction, where when the machine instruction is called by the at least one processor, the foregoing information displaying method is implemented.
According to a fifth aspect, an embodiment of the present invention provides a machine readable medium, where the machine readable medium stores a machine instruction, and when the machine instruction is called by at least one processor, the at least one processor is enabled to perform the foregoing information displaying method.

DETAILED DESCRIPTION
As described above, usually, an operating status of a system may be observed by using a user interface. However, when information displayed on a user interface is relatively much, the information may be displayed incompletely and may be mutually interfered. 
An embodiment of the present invention provides an information displaying method, apparatus, and system, so as to display various information of a system on a user interface clearly and completely, and the information are not mutually interfered.
At least one component of a system may be displayed on a user interface of a main device, and related information, for example, the foregoing data curve, the device status information, or the element logic diagram, of a first part in the at least one component may be displayed on the user interface of the main device. If a first input operation (the first input operation is used for instructing to display the related information of the first part on an auxiliary device) of a user on the user interface of the main device is detected, the related information of the first part is stopped being displayed on the user interface of the main device, and the related information of the first part is sent to the auxiliary device.
Part of information is transferred to a user interface of an auxiliary device for displaying, so that information displaying of a main device is not affected, and the information of a system is displayed more clearly and more complete.
In addition, after the related information of the first part is displayed on a user interface of an auxiliary device, if a second input operation (the second input operation is used for instructing to re-display the related information of the first part on the main device) of the user on the user interface of the auxiliary device is detected, the related information of the first part is stopped being displayed on the user interface of the auxiliary device, and a first instruction message (the first instruction message is used for instructing the main device to re-display the related information of the first part on the user interface of the main device) is sent to the main device. After receiving the instruction message, the main device re-displays the related information of the first part on the user interface of the main device.
In addition, after the related information of the first part is displayed on a user interface of an auxiliary device, if a third input operation (the third input operation is used for instructing to display the related information of the first part on another auxiliary device) of the user on the user interface of the auxiliary device is detected, the related information of the first part is stopped being displayed on the user interface of the auxiliary device, and a second instruction message (the second instruction message is used for instructing the main device to display the related information of the first part on a user interface of the another auxiliary device) is sent to the main device. After receiving the instruction message, the main device sends the related information of the first part to the another auxiliary device, and no longer sends the related information of the first part to the initial auxiliary device.
Further, the first input operation, the second input operation, and the third input operation may be choosing the related information of the first part and dragging the related information of the first part at a relatively quick speed, or choosing the related information of the first part and moving the related information of the first part to an icon displayed on the current user interface.
This embodiment of the present invention is described in detail below with reference to the accompanying drawings.
FIG. 2 is a schematic structural diagram of an information displaying system according to an embodiment of the present invention. As shown in FIG. 2, the information displaying system 100 includes: a main device 10 and at least one auxiliary device 20 (if at least two auxiliary devices 20 exist, it is referred to as "a first auxiliary device 20, a second auxiliary device 20, …" ； if only one auxiliary device 20 exists, it is referred to as "a first auxiliary device 20" ) .
The main device 10 is configured to: display, on a user interface of the main device 10, at least one component of a system to be monitored and related information of a first part in the at least one component； detect a first input operation on the user interface of the main device 10, where the first input operation is used for instructing to display the related information of the first part on a first auxiliary device 20； and after the first input operation is detected, stop displaying the related information of the first part on the user interface of the main device 10, and send the related information of the first part to the first auxiliary device 20.
The first auxiliary device 20 is configured to: receive the related information of the first part from the main device 10, and display the received related information of the first part on a user interface of the first auxiliary device 20.
The main device 10 and the auxiliary device 20 are both devices having a displaying apparatus, and can display the user interfaces. A user may perform an input operation on the user interface, for example, a screen-touch operation, or an operation on the user interface by using a mouse. The auxiliary device 20 may be a mobile phone, a tablet computer, or may be a portable electronic device such as a watch or a band.
The main device 10 and the auxiliary device 20 may perform information transmission in a wireless manner. If at least two auxiliary devices 20 exist, the auxiliary devices 20 may perform information transmission in a wireless manner. A usable wireless communications technology includes but is not limited to: various short-distance wireless communications technologies, for example, Bluetooth, NFC (Near Field Communication) , WiFi (Wireless Fidelity) and Zigbee, as long as the wireless communication between devices can be implemented. The devices also perform information transmission in a wired manner. For  example, communication is performed by using a cable connected between the devices.
The system to be monitored may be the foregoing industrial system, or may be an agricultural system, a medical system, or a communications system. The systems each include at least one component. The component may be an element, or may be a subsystem. Still using the electric power plant in FIG. 1 as an example, a component of the industrial system may be a steam turbine, or may be a condenser in the steam turbine, or may be a circulating water system in the steam turbine.
The user interface of the main device 10 displays at least one part of the system to be monitored. When the user clicks a button or an icon on the user interface, related information of a part corresponding to the button or the icon may be displayed. For distinguishing, a system component whose related information is displayed is referred to as "the first part" .
The related information of the first part may include but is not limited to the assistance information such as the data curve 101, the device status information 102, the element logic diagram 103, and the guidance information 104. The assistance information may be presented in a pop-up window form.
The data curve 101 may be used for displaying a change of a parameter.
Still using the foregoing electric power plant as an example, usually, a main subsystem, for example, a system diagram of a main power generator, of the electric power plant may be displayed on a monitor. When observing the subsystem, an operator also needs to monitor multiple key parameters, for example, a steam water temperature, a pressure, or a speed, of the subsystem. An abnormal change of a value of a key parameter may be represented by using a data curve 101 of the key parameter. The operator may quickly realize a problem and adopt a corresponding countermeasure by observing the data curve 101. By means of this embodiment of the present invention, the data curve 101 may be transferred from a user interface of a monitor (an example of the main device 10) to a mobile phone (an example of the first auxiliary device 20) . In this way, the operator may observe the change of the value of the key parameter without affecting an operation on the  user interface of the monitor. In addition, if the monitor and the mobile phone transmit information in a wireless manner, and the mobile phone may be carried around, the operator can perform monitoring incessantly even if leaving a controlling room.
The device status information 102 may be used for indicating a status of a device.
Still using the foregoing electric power plant as an example, if the operator wants to check a device, for example, a status of a valve, or a temperature of a boiler, the operator may click a button of the device on the user interface of the monitor, that is, a pop-up window may be presented on the user interface, and the pop-up window displays status information of the device. Because of a limitation of space of the user interface, the pop-up window may cover displayed information. By means of this embodiment of the present invention, the pop-up window may be transferred to an assistant mobile device (an example of the auxiliary device 20) for displaying.
The element logic diagram 103 may be used for indicating a logic relationship connection between elements and an internal logic connectivity of each element. By analyzing the element logic diagram 103, the user may find an internal association between the elements, and may directly locate a fault problem and perform a corresponding disconnection/connection switching operation.
The guidance information 104 may be used for giving, when an alarm occurs, detailed description information of the alarm.
Still using the foregoing electric power plant as an example, when an alarm occurs, the operator may need to search for detailed description information of the alarm for fault diagnosis. By means of this embodiment of the present invention, the detailed description information of the alarm may be displayed on the mobile device rather than being displayed on the monitor. In this way, the operator may perform a fault diagnosis operation on the user interface of the monitor while referring to the detailed description information of the alarm on a user interface of the mobile device.
An information displaying method provided in an embodiment of the present invention is described below with reference to FIG. 3. A main device 10 and an auxiliary device 20 in  the method may respectively be the main device 10 and the auxiliary device 20 in the information displaying system 100 shown in FIG. 1. As shown in FIG. 3, the method may include the following steps.
S301: A main device 10 establishes a connection with a first auxiliary device 20.
The main device 10 communicates with the first auxiliary device 20 in a wireless manner. The main device 10 may establish the connection with the first auxiliary device 20 in the following manner: The main device 10 pre-records a list of optional auxiliary devices 20. As shown in FIG. 4, a user interface of the main device 10 may display a second icon 42. A user clicks the second icon 42, and the main device 10 expands a device list, where the list lists the pre-recorded optional auxiliary devices 20. The user chooses one of the auxiliary devices 20 as a the first auxiliary device 20. The main device 10 sends a connection establishment request 44 to the chosen first auxiliary device 20. After receiving the connection establishment request, as shown in FIG. 4, the first auxiliary device 20 may display a prompt button 43 on a user interface of the first auxiliary device 20, to prompt the user whether to agree to establish the connection with the main device 10. If the user clicks the button 43 to determine that the connection may be established with the main device 10, the first auxiliary device 20 returns a connection establishment response 45 in response to the connection establishment request 44. After the main device 10 receives the connection establishment response 45, the connection between the main device 10 and the first auxiliary device 20 are successfully established.
Description is performed below by using an example in which the main device 10 communicates with the first auxiliary device 20 by using a WiFi technology, and the first auxiliary device 20 is a mobile terminal. The main device 10 may run a server application. The first auxiliary device 20 may run a client application. The main device 10 and the first auxiliary device 20 may be connected to a same wireless local area network.
If the server application and the client application are both a desktop application, a socket technology may be used to establish the connection between the main device 10 and the auxiliary device 20 and perform information transmission between the main device 10 and the auxiliary device 20. In this case, the server application and the client application  may be both a native application (native application) . If the server application and the client application are both an application based on web, a web socket technology may be used to establish the connection and perform information transmission. In this case, the server application and the client application may be both a web application .
When the user enables the client application on the first auxiliary device 20, the first auxiliary device 20 may notify the main device 10 that a first auxiliary device 20 exists and may establish the connection with the main device 10. After receiving the notification, the main device 10 may send the connection establishment request 44 to the first auxiliary device 20. After receiving the connection establishment request 44, the first auxiliary device 20 prompts the user whether to allow establishing the connection with the main device 10 (for example, prompting the user whether to allow the connection by using the prompt button 43) . If the user determines that the connection may be established with the main device 10, the first auxiliary device 20 sends the connection establishment request 45 to the main device 10. After the main device 10 receives the first auxiliary device 20, the main device 10 and the first auxiliary device 20 may establish a two-way communication channel, and further transmit information.
In the foregoing process, the main device 10 sends the connection establishment request to the first auxiliary device 20. Certainly, the first auxiliary device 20 may send a connection establishment request to the main device 10, and the main device 10 prompts the user whether to allow a connection with the first auxiliary device 20. If the user determines that the connection may be established with the first auxiliary device 20. A connection establishment process is performed.
If at least two auxiliary devices 20 are connected to the main device 10 simultaneously, a server program running on the main device 10 may distinguish the auxiliary devices 20 according to an IP (Internet Protocol) addresses of the auxiliary devices 20. Mutual recognition may be performed according to the IP addresses between the main device 10 and the auxiliary device 20 and between the auxiliary devices 20.
S302: The main device 10 displays, on a user interface of the main device 10, at least one component of a system to be monitored, as shown in FIG. 5A.
S303: The main device 10 displays, on the user interface of the main device 10, related information of a first part in the at least one component.
Specifically, when a user chooses a first part on the user interface, and determines to display related information (using the data curve 101 as an example herein) of the first part, the main device 10 displays the data curve 101 on the user interface of the main device 10. A display location of the data curve 101 may be near the right side or lower side of the first part, and a specific location may be determined by the main device 10. The data curve 101 may cover a part of the system to be monitored that is displayed on the user interface, as shown in FIG. 5B.
For steps S301 to S303, step S301 may be performed after step S302 and step S303, or may be performed before the two steps.
S304: The main device 10 detects a first input operation on the user interface of the main device 10, where the first input operation is used for instructing to display the data curve 101 on the first auxiliary device 20.
S305: After the first input operation is detected, the main device 10 stops displaying the data curve 101 on the user interface of the main device 10.
S306: After the first input operation is detected, the main device 10 sends the data curve 101 to the first auxiliary device 20.
The first input operation may be implemented in multiple optional manners.
Manner 1
The main device 10 is only connected to one auxiliary device 20, that is, the first auxiliary device 20.
As shown in FIG. 5C, a user may choose the data curve 101 on the user interface of the main device 10 and drag the data curve 101 at a speed faster than a preset first speed.
Manner 2
The main device 10 is only connected to one auxiliary device 20, that is, the first auxiliary device 20.
As shown in FIG. 5D, a user may choose the data curve 101 on the user interface of the main device 10 and move the data curve 101 to a first icon 41. Optionally, the first icon 41 may be a same icon as the second icon 42.
Manner 3
The main device 10 is connected to at least two auxiliary devices 20.
As shown in FIG. 5E, a user may choose the data curve 101 on the user interface of the main device 10 and drag the data curve 101 at a speed faster than a preset first speed.
The main device 10 expands a device list 46 in response to the input operation of the user, where the device list 46 lists all auxiliary devices 20 connected to the main device 10. The user may choose the first auxiliary device 20 from the device list 46.
Manner 4
The main device 10 is connected to at least two auxiliary devices 20.
As shown in FIG. 5F, a user may choose the data curve 101 on the user interface of the main device 10 and move the data curve 101 to a first icon 41. Optionally, the first icon 41 may be a same icon as the second icon 42.
The main device 10 expands a device list 46 in response to the input operation of the user, where the device list 46 lists all auxiliary devices 20 connected to the main device 10. The user may choose the first auxiliary device 20 from the device list 46.
Manner 5
The main device 10 is connected to at least two auxiliary devices 20. When being connected to an auxiliary device 20 each time, the main device 10 displays a first icon 41 corresponding to the auxiliary device 20 on the user interface of the main device 10. That is, for each auxiliary device 20 connected to the main device 10, a first icon 41 corresponding to the auxiliary device 20 exists on the user interface of the main device 10. Optionally, identification information such as a name, for example, DEV A and DEV B shown in FIG 5G, of the corresponding auxiliary device 20 is displayed beside each first icon 41.
As shown in FIG. 5G, a user may choose the data curve 101 on the user interface of the  main device 10 and move the data curve 101 to a first icon 41. The data curve 101 may be transferred to a user interface of an auxiliary device 20 corresponding to the first icon 41 for displaying.
Optionally, the first icon 41 and the second icon 42 may be displayed outside a display area of the at least one component on the user interface of the main device 10.
S307: The first auxiliary device 20 displays the received data curve 101 on a user interface of the first auxiliary device 20, as shown in FIG. 6A.
Optionally, as shown in FIG. 2, the data curve 101 may be transferred to a first auxiliary device 20 for displaying, and the device status information 102 and the element logic diagram 103 may be transferred to another auxiliary device 20 for displaying, for example, being transferred to a second auxiliary device 20 for displaying. The device status information 102 may be transferred to the second auxiliary device 20 for displaying first, and then the element logic diagram 103 is transferred to the second auxiliary device 20 for displaying.
Optionally, after step S307, the method may further include the following steps.
S308: The main device 10 sends the updated data curve 101 to the first auxiliary device 20.
The data curve 101 may change in real time with operating of the system to be monitored. Therefore, the main device 10 may update the data curve 101, and send the updated data curve 101 to the first auxiliary device 20. In this way, the first auxiliary device 20 may display the data curve 101 that is updated in real time.
S309: The first auxiliary device 20 displays the received updated data curve 101, as shown in FIG. 6B.
Optionally, the user may perform an operation such as zooming in, zooming out, or dragging on the first part displayed on the auxiliary device 20. In addition, the user interface of the auxiliary device 20 may be classified into the following two manners according to whether a user can perform an operation such as control processing on the first part on the user interface of the auxiliary device 20.
Manner 1
Only the related information of the first part is displayed, and an operation of control processing that is inputted by the user on the user interface of the auxiliary device 20 and that is performed for the first part is not received. For example, the first part is a valve of a steam turbine, and the operation of control processing may be closing the valve of the steam turbine.
Manner 2
Not only the related information of the first part is displayed, but also an operation of control processing that is inputted by the user on the user interface of the auxiliary device 20 and that is performed for the first part is received.
For Manner 1, if the user wants to perform the operation of control processing on the first part, the user may transfer the related information of the first part back to the user interface of the main device 10 for displaying, and further perform the operation of control processing on the user interface of the main device 10.
For Manner 2, the user may directly perform the operation on the user interface of the auxiliary device 20. The auxiliary device 20 sends, to the main device 10, information about the operation of control processing that is performed by the user. The main device 10 processes the information about the operation of control processing. Information about a processing result may be sent to the auxiliary device 20, and may be displayed on the user interface of the auxiliary device 20, or may be displayed on the user interface of the main device 10.
The following focuses on related steps of Manner 1 for description.
After step S307, the method may further include the following steps.
S310: The first auxiliary device 20 detects a second input operation on the user interface of the first auxiliary device 20, where the second input operation is used for instructing to display the related information of the first part on the main device 10.
The second input operation may be implemented in multiple optional manners.
Manner 1
As shown in FIG. 7A, a user may choose the data curve 101 on the user interface of the first auxiliary device 20 and drag the data curve 101 at a speed faster than a preset second speed.
Manner 2
As shown in FIG. 7B, the user interface on the first auxiliary device 20 may display a third icon 47. A user may choose the data curve 101 on the user interface of the first auxiliary device 20 and move the data curve 101 to the third icon 47.
Optionally, the third icon 47 is located outside a display area of the data curve 101 on the user interface of the first auxiliary device 20.
S311: After the second input operation is detected, the first auxiliary device 20 stops displaying the data curve 101 on the user interface of the first auxiliary device 20.
S312: After the second input operation is detected, the first auxiliary device 20 sends a first instruction message to the main device 10, where the first instruction message is used for instructing the main device 10 to re-display the data curve 101 on the user interface of the main device 10.
S313: After receiving the first instruction message from the first auxiliary device 20, the main device 10 re-displays the data curve 101 on the user interface of the main device 10.
In the manner, the related information of the first part may be switched to display between the main device 10 and the auxiliary device 20. Optionally, the related information of the first part may be switched from one auxiliary device 20 to another auxiliary device 20 for displaying.
For the optional solution, after establishing a connection with each auxiliary device 20, the main device 10 may record a list of connected auxiliary devices 20, and sends the list of the connected auxiliary devices 20 to each auxiliary device 20. In this way, each auxiliary device 20 may know not only the main device 10 connected to the auxiliary device 20 itself  but also the auxiliary devices 20 connected to the main device 10.
Still using the foregoing scenario as an example, the data curve 101 is transferred by the main device 10 to the user interface of the first auxiliary device 20 for displaying. The first auxiliary device 20 detects a third input operation on the user interface of the first auxiliary device 10, where the third input operation is used for instructing to display the data curve 101 on a second auxiliary device (20) . After the third input operation inputted by a user is detected, he first auxiliary device 20 stops displaying the data curve 101 on the user interface of the first auxiliary device (20) , and sends a second instruction message to the main device (10) , where the second instruction message is used for instructing the main device (10) to display the data curve 101 on a user interface of the second auxiliary device (20) . After receiving the second instruction message, the main device 10 stops sending the data curve 101 to the first auxiliary device (20) , and sends the data curve 101 to the second auxiliary device (20) . After receiving the data curve 101, the second auxiliary device 20 displays the data curve 101 on the user interface of the second auxiliary device 20.
The third input operation may also be implemented in multiple optional manners.
Manner 1
As shown in FIG. 8A, a user may choose the data curve 101 on the user interface of the main device 10 and drag the data curve 101 at a speed faster than a preset third speed.
The main device 10 expands a device list 46 in response to the input operation of the user, where the device list 46 lists all auxiliary devices 20 (in addition to the first auxiliary device 20) connected to the main device 10. The user may choose the second auxiliary device 20 from the device list 46.
Manner 2
As shown in FIG. 8B, the user interface of the first auxiliary device 20 displays multiple fourth icons 48, where one fourth icon 48 corresponds to the main device 10, and the remaining fourth icons respectively correspond to other auxiliary devices 20 connected to the main device 10 other than the first auxiliary device 20. Optionally, identification information such as a name of a corresponding device is displayed beside each fourth icon  48, for example, MD (representing the main device 10) , DEV B (representing the second auxiliary device 20) , and DEV C (representing a third auxiliary device 20) in FIG. 8B.
A user may choose the data curve 101 on the user interface of the first auxiliary device 20, and move the data curve 101 to a fourth icon 48, for example, moving the data curve 101 to a fourth icon 48 corresponding to the second auxiliary device 20. The data curve 101 may be transferred to the user interface of the second auxiliary device 20 for displaying.
In FIG. 8C, the main device 10 is connected to three auxiliary devices 20. Each device displays fourth icons 48 of the other devices and corresponding device names. Identification is performed between the main device 10 and the auxiliary devices 20 by using an IP address. In the device names, MD represents the main device 10, DEV A represents the first auxiliary device 20, DEV B represents the second auxiliary device 20, DEV C represents a third auxiliary device 20.
