[0049] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the drawings in the present application only serve the purpose of explanation and description and are not used to limit the scope of protection of the present application. In addition, it should be understood that the schematic drawings are not drawn in real proportion. The flowchart used in this application shows the operations implemented according to some embodiments of the present application. It should be understood that the operations of the flowchart can be implemented out of sequence, and the steps without logical context can be reversed in order or implemented simultaneously. In addition, those skilled in the art, under the guidance of the content of the present application, can add one or more other operations to the flowchart, or remove one or more operations from the flowchart.

[0050] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0051] In order to enable those skilled in the art to use the contents of this application, the following implementation is provided in combination with a specific application scenario of "turning the display screen on and off". For those skilled in the art, the general principles defined herein can be applied to other embodiments and application scenarios without departing from the spirit and scope of this application.

[0052] The following methods, devices, electronic devices or computer-readable storage media of the embodiments of the present application can be applied to any scenario where a display screen needs to be turned on and off. The embodiments of the present application are not limited to specific application scenarios. Any solution using the power management control system and method of the display screen provided by the embodiments of the present application is within the scope of protection of this application.

[0053] It is worth noting that before the present application was submitted, in the existing solutions, with the development of the industrial Internet, the digitization and intelligence of products have become important parameters for measuring product technical indicators, and a single display function can no longer meet the needs of users. This has put forward upgrade requirements for the display screen that originally realized a single human-computer interaction function. Among them, the existing technology can only remotely monitor mechanical equipment when the mechanical equipment is in use, which lacks flexibility.

[0054] In response to the above problems, the power management control system of the embodiment of the present application includes a display screen, a power control unit and a power supply, wherein the power control unit is used to start the time timer when it is detected that the display screen is turned off, and when the timer time of the time timer is reached, turn on the power and control the display screen to turn on, and after the display screen is turned on for a preset time, disconnect the power and control the display screen to turn off. Based on the above method, when the display screen is in the off state, the pre-buried time timer is started by the power control unit, and when the timer time is reached, the display screen is controlled to turn on, and the display screen can be turned off again in a specific scenario. The timed power-on time can be flexibly configured according to user needs, which is suitable for various usage scenarios. When the mechanical equipment is not in use, the user can still remotely understand the status of the mechanical equipment and realize remote monitoring of the mechanical equipment.

[0055] It should be noted that mechanical equipment includes but is not limited to excavators, forklifts, cranes, and hoists.

[0056] To facilitate the understanding of the present application, the technical solution provided by the present application is described in detail below in conjunction with specific embodiments.

[0057] See also Figure 1 , Figure 2 As shown, Figure 1 One of the structural schematic diagrams of a power management control system 100 for a display screen provided in an embodiment of the present application; Figure 2 FIG2 shows a second structural diagram of a power management control system 100 for a display screen provided in an embodiment of the present application. Figure 1 As shown, the power management control system 100 of the display screen provided in the embodiment of the present application includes a display screen 110, a power control unit 120 and a power supply 130, and the power control unit 120 is connected to the display screen 110 and the power supply 130 respectively.

[0058] The display screen 110 is a screen of the mechanical device, which is used to display various parameters of the mechanical device and realize human-computer interaction, that is, the user can operate the display screen 110, and the display screen 110 can give corresponding feedback to the user's operation. The power control unit 120 is a bridge between the display screen 110 and the power supply 130 of the display screen 110. The power control unit 120 can be used to turn on or off the power supply 130, thereby realizing the opening and closing of the display screen 110. The power supply 130 is a power supply 130 that provides electrical energy to the display screen 110.

[0059] It should be noted that the power control unit 120 can be a microcontroller, such as STM8, whose CPU core has 6 internal registers, through which data processing can be performed efficiently. The instruction set of STM8 supports 80 basic 20 addressing modes, and the 6 internal registers of the CPU have addressable addresses.

[0060] The power control unit 120 is used to start a time timer when it is detected that the display screen 110 is turned off, and when the timing of the timer is reached, turn on the power supply 130 and control the display screen 110 to turn on, and disconnect the power supply 130 and control the display screen 110 to turn off after the display screen 110 is turned on for a preset time.

[0061] In a specific implementation, usually, when the user is not using the mechanical device, the display screen 110 of the mechanical device will be turned off. If the mechanical device is not in use for a long time, it will be difficult for the user to remotely understand the state of the mechanical device and cannot remotely monitor the mechanical device. In this regard, the present application pre-sets a timer, and the power control unit 120 starts the time timer when detecting that the display screen 110 is turned off. In this way, when the timer is reached, the power supply 130 is turned on to control the display screen 110 to turn on. Here, the user can flexibly set the timer according to his actual needs, and can still allow the user to remotely understand the state of the mechanical device when the mechanical device is not in use, and realize remote monitoring of the mechanical device. Here, after each time the display screen 110 is started by the time timer and the power control unit 120, since the mechanical device is not in use at this time, the display screen 110 cannot be kept in the on state all the time, so the present application sets the corresponding display screen 110 on time in this case, that is, the preset duration, wherein the preset duration can be set according to actual needs. After the display screen 110 is turned on for the preset duration each time, the power supply 130 is disconnected and the display screen 110 is controlled to turn off.

[0062] It should be noted that when the smart screen is in the off state, the power control unit 120 starts the embedded timer, and the display screen 110 is powered on in the background when the timer is up, and the display screen 110 is powered off in a specific scenario. This function can flexibly configure the timer power-on time according to customer needs, which is suitable for various usage scenarios, allowing customers to understand the device dynamics in real time. The display screen 110 is provided with a timer trigger power-on function, and the user can flexibly configure the timer time, which is suitable for various application scenarios and easy to test.

[0063] In a possible implementation, Figure 2 As shown, the power management control system 100 of the display screen also includes a core processing unit 140, and the core processing unit 140 is connected to the power control unit 120; the core processing unit 140 is used to receive the scheduled power-on time input through the scheduled power-on function interface, and send the scheduled power-on instruction carrying the scheduled power-on time to the power control unit 120; the power control unit 120 is used to start the countdown function of the scheduled power-on after receiving the scheduled power-on instruction, and control the display screen 110 to turn on when the scheduled power-on time is reached.

[0064] In a specific implementation, when the display screen 110 of the mechanical equipment is in an on state, the user can interact with the display screen 110. Here, the display screen 110 provides a scheduled power-on function. The user can manually enter the scheduled power-on time on the scheduled power-on function interface displayed on the display screen 110, or determine the scheduled power-on time by selecting a time. The scheduled power-on time can be set according to the actual needs of the user. After receiving the scheduled power-on time set by the user, the core processing unit 140 sends a scheduled power-on instruction carrying the scheduled power-on time to the power control unit 120. After receiving the scheduled power-on instruction, the power control unit 120 starts the countdown function of the scheduled power-on, and controls the display screen 110 to turn on when the scheduled power-on time is reached. Here, the countdown function of the scheduled power-on is used for timing. For example, if the scheduled power-on time is 1 hour, the display screen 110 is turned on after the countdown of 1 hour.

[0065] It should be noted that the scheduled power-on function interface of the display screen 110 can also verify the identity of the user. Only users who have successfully passed the identity verification, that is, authorized users, can set the scheduled power-on time on the scheduled power-on function interface.

[0066] Here, when the display screen 110 is in the on state, an authorized user can input the scheduled power-on time through the scheduled power-on function interface on the display screen 110, so that the core processing unit 140 sends the scheduled power-on instruction to the power control unit 120 through the serial port. After the power control unit 120 receives the scheduled power-on instruction, the power control unit 120 parses the scheduled power-on instruction received by the serial port interrupt, and starts to turn on the scheduled power-on countdown function after parsing, and controls the display screen 110 to turn on when the scheduled power-on time is reached. In this way, the present application provides a scheduled power-on function for the display screen 110, and the user can specify that the display screen 110 be turned on at a certain time in the future, which provides a guarantee for remote control of mechanical equipment.

[0067] In a possible implementation, Figure 2 As shown, the power control unit 120 is used to send a shutdown instruction corresponding to the shutdown signal to the core processing unit 140 when a shutdown signal is detected; the core processing unit 140 is used to control the display screen 110 to turn off after receiving the shutdown instruction.

[0068] Here, the core processing unit 140 is a bridge between the power control unit 120 and the display screen 110. The core processing unit 140 can receive various instructions sent by the power control unit 120, analyze and process the instructions, and then send them to the display screen 110 so that the display screen 110 can take corresponding measures according to the instructions.

[0069] In a specific implementation, when the power control unit 120 detects a shutdown signal, that is, when the power control unit 120 detects a shutdown signal generated by the user operating the mechanical device, the shutdown command corresponding to the shutdown signal is first sent to the core processing unit 140. The core processing unit 140 parses the shutdown command to determine whether to respond to the shutdown command. For example, a normal shutdown will respond to the shutdown command. If it is an abnormal shutdown, an abnormal information will be prompted on the display screen 110, and after the user confirms the abnormality, the shutdown command will not be responded to. If the user confirms that it is not abnormal, the shutdown command will be responded to normally. Here, after the core processing unit 140 responds to the shutdown command, the power supply 130 is disconnected, and the display screen 110 is controlled to turn off. In this way, the risk of data loss caused by hardware forced power off can be avoided, and the information integrity of the mechanical equipment can be guaranteed.

[0070] In a possible implementation, Figure 1 As shown, the power control unit 120 is used to enable the countdown function of the scheduled power-on according to the following steps: after receiving the scheduled power-on instruction, the scheduled power-on instruction is parsed to obtain the scheduled power-on time, the countdown function of the scheduled power-on is enabled, and when the scheduled power-on time is reached, the display screen 110 is controlled to turn on.

[0071] In a specific implementation, after receiving the scheduled power-on instruction sent by the core processing unit 140, the power control unit 120 will parse the scheduled power-on instruction, and parse out the scheduled power-on time from the scheduled power-on instruction. At this time, the countdown function of the scheduled power-on is turned on. In this way, when the scheduled power-on time is reached, the display screen 110 can be controlled to turn on.

[0072] Here, when the display screen 110 is in the on state, an authorized user can input the scheduled power-on time through the scheduled power-on function interface on the display screen 110, so that the core processing unit 140 sends the scheduled power-on instruction to the power control unit 120 through the serial port. After the power control unit 120 receives the scheduled power-on instruction, the power control unit 120 parses the scheduled power-on instruction received by the serial port interrupt, and starts to turn on the scheduled power-on countdown function after parsing, and controls the display screen 110 to turn on when the scheduled power-on time is reached. In this way, the present application provides a scheduled power-on function for the display screen 110, and the user can specify that the display screen 110 be turned on at a certain time in the future, which provides a guarantee for remote control of mechanical equipment.

[0073] In a possible implementation, Figure 2 As shown, the power control unit 120 is used to send a power-on instruction corresponding to the power-on signal to the core processing unit 140 when a power-on signal is detected; the core processing unit 140 is used to control the display screen 110 to turn on after receiving the power-on instruction.

[0074] Here, the core processing unit 140 is a bridge between the power control unit 120 and the display screen 110. The core processing unit 140 can receive various instructions sent by the power control unit 120, analyze and process the instructions, and then send them to the display screen 110 so that the display screen 110 can take corresponding measures according to the instructions.

[0075] In a specific implementation, when the power control unit 120 detects a power-on signal, that is, when the power-on signal is detected by the user operating the mechanical device, the power-on instruction corresponding to the power-on signal is first sent to the core processing unit 140. The core processing unit 140 parses the power-on instruction to determine whether to respond to the power-on instruction. Here, after the core processing unit 140 responds to the power-on instruction, the power supply 130 is turned on, and the display screen 110 is controlled to turn on.

[0076] It should be noted that when patrolling to detect whether the device power 130 switch of the mechanical equipment is turned on, the power control unit 120 first turns on the display screen 110, and at the same time notifies the core processing unit 140 that this is power-on. The core processing unit 140 performs normal power-on application logic processing to control the display screen 110 to turn on.

[0077] Here, if the patrol detection switch is turned on, the power control unit 120 powers on the display screen 110 through the digital signal Do0, and at the same time notifies the core processing unit 140 to power on the switch through the analog signal Do1; if the power switch 130 is turned off, the timing patrol trigger time timer is started. When the timing time is greater than the maximum time set by the user, the display screen 110 enters the background operation, the power control unit 120 turns off the backlight of the display screen 110, turns off the LCD power supply 130, and powers on the core processing unit 140 through the digital signal Do0, controls the analog signal Do1 to notify that this is a trigger power-on, and starts the trigger shutdown countdown timing processing.

[0078] In a possible implementation, Figure 2 As shown, the power control unit 120 is also used to: detect whether the display screen 110 is positioned when the shutdown signal is detected; if so, directly send the shutdown instruction corresponding to the shutdown signal to the core processing unit 140; if not, when it is detected that the on-time of the display screen 110 reaches the set maximum on-time, send the shutdown instruction corresponding to the shutdown signal to the core processing unit 140.

[0079] In a specific implementation, when the power control unit 120 detects a shutdown signal from a user operating the mechanical device, it detects whether the display screen 110 is located at this time. Only when the display screen 110 is located can the user remotely know the location of the mechanical device. Here, when it is detected that the display screen 110 is located, the shutdown command corresponding to the shutdown signal is directly sent to the core processing unit 140, so that the core processing unit 140 can respond to the shutdown command in time and control the display screen 110 to turn off; when it is detected that the display screen 110 is not located, the shutdown may not be executed first, but when it is detected that the opening time of the display screen 110 reaches the set maximum opening time, the shutdown command corresponding to the shutdown signal is sent to the core processing unit 140. In this way, it can be guaranteed that there is sufficient time to locate the mechanical device so that the user can determine the location of the mechanical device.

[0080] It should be noted that in the present application, functions such as timed patrol triggering power-on, scheduled startup, and delayed power-off of the display screen 110 can be realized. Through the timed power-on function of the display screen 110, the user can flexibly configure the timing time, which is suitable for various application scenarios; through the scheduled startup function of the display screen 110, the user can specify that the display screen 110 will be powered on at a certain time in the future, providing technical support for the remote control of mechanical equipment; through the delayed power-off function of the display screen 110, the risk of data loss and system damage of the display screen 110 caused by forced power-off of the hardware can be avoided.

[0081] In the embodiment of the present application, the power management control system 100 of the display screen includes a display screen 110, a power control unit 120 and a power supply 130, wherein the power control unit 120 is used to start the time timer when detecting that the display screen 110 is turned off, and when the timer time of the time timer is reached, connect the power supply 130 and control the display screen 110 to turn on, and after the display screen 110 is turned on for a preset time, disconnect the power supply 130 and control the display screen 110 to turn off. Based on the above method, when the display screen 110 is in the off state, the pre-buried time timer is started by the power control unit 120, and when the timer time is reached, the display screen 110 is controlled to turn on, and the display screen 110 can also be turned off in a specific scenario. The timed power-on time can be flexibly configured according to user needs, which is suitable for various usage scenarios. When the mechanical equipment is not in use, the user can still remotely understand the status of the mechanical equipment and realize remote monitoring of the mechanical equipment.

[0082] Based on the same application concept, the embodiment of the present application also provides a power management control method corresponding to the power management control system of the display screen provided in the above embodiment. Since the principle of solving the problem by the method in the embodiment of the present application is similar to the power management control system of the display screen in the above embodiment of the present application, the implementation of the method can refer to the implementation of the method, and the repeated parts will not be repeated.

[0083] like Figure 3-Figure 5 As shown, Figure 3 A flow chart showing a power management control method for a display screen provided in an embodiment of the present application is shown; Figure 4 A flow chart showing another power management control method for a display screen provided in an embodiment of the present application is shown; Figure 5 A flow chart of another display screen power management control method provided in an embodiment of the present application is shown.

[0084] like Figure 3 As shown, a flow chart of a power management control method for a display screen is provided, and the power management control method for a display screen includes:

[0085] S301: When it is detected that the display screen is turned off, start timing, and when the timing time is reached, control the display screen to turn on.

[0086] S302: After the display screen is turned on for a preset time, controlling the display screen to turn off.

[0087] In a specific implementation, usually, when the user is not using the mechanical device, the display screen of the mechanical device will be turned off. If the mechanical device is not in use for a long time, it will be difficult for the user to remotely understand the status of the mechanical device and cannot remotely monitor the mechanical device. In this regard, the present application pre-sets a timer, and when the display screen is detected to be turned off, the time timer is turned on. In this way, when the timer is reached, the power is turned on to control the display screen to turn on. Here, the user can flexibly set the timing time according to his actual needs, and can still allow the user to remotely understand the status of the mechanical device when the mechanical device is not in use, and realize remote monitoring of the mechanical device. Here, after each time the timer and the control display screen are started, since the mechanical device is not in use at this time, the display screen cannot be kept in the on state all the time, so the present application sets the corresponding display screen on time in this case, that is, the preset duration, wherein the preset duration can be set according to actual needs. After the display screen is turned on for the preset duration each time, the power is disconnected and the display screen is controlled to turn off.

[0088] It should be noted that when the smart screen is in the off state, the embedded timer is started, and the display screen is powered on in the background when the timer is up, and the display screen is powered off in a specific scenario. This function can flexibly configure the timer power-on time according to customer needs, which is suitable for various usage scenarios, allowing customers to understand the dynamics of the device in real time. The display screen timer trigger power-on function is provided, and users can flexibly configure the timer time, which is suitable for various application scenarios and easy to test.

[0089] In a possible implementation, Figure 4 As shown, a flow chart of another power management control method for a display screen is provided, and the power management control method for the display screen includes:

[0090] S401: receiving a scheduled power-on time input through a scheduled power-on function interface, and sending a scheduled power-on instruction carrying the scheduled power-on time to the display screen.

[0091] S402: starting the countdown function of the scheduled power-on time, and controlling the display screen to turn on when the scheduled power-on time is reached.

[0092] In a specific implementation, when the display screen of the mechanical equipment is in the on state, the user can interact with the display screen. Here, the display screen provides a scheduled power-on function. The user can manually enter the scheduled power-on time through the scheduled power-on function interface displayed on the display screen, or determine the scheduled power-on time by selecting the time. The scheduled power-on time can be set according to the actual needs of the user. After receiving the scheduled power-on time set by the user, the countdown function of the scheduled power-on is turned on, and when the scheduled power-on time is reached, the display screen is controlled to turn on. Here, the countdown function of the scheduled power-on is used for timing. For example, if the scheduled power-on time is 1 hour, the display screen is turned on after the countdown of 1 hour.

[0093] It should be noted that the scheduled power-on function interface of the display screen can also verify the identity of the user. Only users who have successfully passed the identity verification, that is, authorized users, can set the scheduled power-on time on the scheduled power-on function interface.

[0094] Here, when the display screen is in the on state, authorized users can enter the scheduled power-on time through the scheduled power-on function interface on the display screen. In this way, after receiving the scheduled power-on instruction, the received scheduled power-on instruction is parsed, and the scheduled power-on countdown function is started after parsing, and when the scheduled power-on time is reached, the display screen is controlled to turn on. In this way, the present application provides a scheduled power-on function for the display screen, and the user can specify that the display screen will be turned on at a certain time in the future, which provides a guarantee for remote control of mechanical equipment.

[0095] In a possible implementation, when a shutdown signal is detected, a shutdown instruction corresponding to the shutdown signal is sent to the display screen, and the display screen is controlled to be turned off.

[0096] In a specific implementation, when a shutdown signal is detected, that is, when a shutdown signal generated by a user operating a mechanical device is detected, a shutdown command corresponding to the shutdown signal is first sent to the display, and the display parses the shutdown command to determine whether to respond to the shutdown command. For example, a normal shutdown will respond to the shutdown command. If it is an abnormal shutdown, an abnormal information will be prompted on the display screen, and after the user confirms the abnormality, the shutdown command will not be responded to. If the user confirms that it is not abnormal, the shutdown command will be responded to normally. Here, after responding to the shutdown command, the power supply is disconnected and the display screen is controlled to turn off. In this way, the risk of data loss caused by hardware forced power off can be avoided, and the information integrity of the mechanical equipment can be guaranteed.

[0097] In a possible implementation, when a power-on signal is detected, a power-on instruction corresponding to the power-on signal is sent to the display screen, and the display screen is controlled to turn on.

[0098] In a specific implementation, after the scheduled power-on instruction is sent, the scheduled power-on instruction will be parsed, and the scheduled power-on time will be parsed from the scheduled power-on instruction. At this time, the countdown function of the scheduled power-on is turned on, so that the display screen can be controlled to turn on when the scheduled power-on time is reached.

[0099] Here, when the display screen is in the on state, authorized users can enter the scheduled power-on time through the scheduled power-on function interface on the display screen. In this way, after receiving the scheduled power-on instruction, the received scheduled power-on instruction is parsed, and the scheduled power-on countdown function is started after parsing, and when the scheduled power-on time is reached, the display screen is controlled to turn on. In this way, the present application provides a scheduled power-on function for the display screen, and the user can specify that the display screen will be turned on at a certain time in the future, which provides a guarantee for remote control of mechanical equipment.

[0100] In a possible implementation, Figure 5 As shown, a flow chart of another power management control method for a display screen is provided, and the power management control method for the display screen includes:

[0101] S501: When the shutdown signal is detected, detecting whether the display screen is positioned.

[0102] S502: If yes, directly sending the shutdown instruction corresponding to the shutdown signal to the display screen.

[0103] S503: If not, when it is detected that the on time of the display screen reaches the set maximum on time, a shutdown instruction corresponding to the shutdown signal is sent to the display screen.

[0104] In a specific implementation, when a shutdown signal of a user operating a mechanical device is detected, it is detected whether the display screen is positioned at this time. Only when the display screen is positioned can the user remotely know the location of the mechanical device. Here, when it is detected that the display screen is positioned, the shutdown command corresponding to the shutdown signal is directly sent to the display screen to control the display screen to turn off. When it is detected that the display screen is not positioned, the shutdown may not be executed first. Instead, when it is detected that the display screen is turned on for a certain period of time, the shutdown command corresponding to the shutdown signal is sent. In this way, sufficient time can be guaranteed to locate the mechanical equipment so that the user can determine the location of the mechanical equipment.

[0105] In the embodiment of the present application, when it is detected that the display screen is turned off, the time timer is started, and when the timer time is reached, the power is turned on and the display screen is controlled to turn on, and after the display screen is turned on for a preset time, the power is disconnected and the display screen is controlled to turn off. Based on the above method, when the display screen is in the off state, the pre-buried time timer is started by the power control unit, and when the timer time is reached, the display screen is controlled to turn on, and the display screen can be turned off again in a specific scenario. The timed power-on time can be flexibly configured according to user needs, which is suitable for various usage scenarios. When the mechanical equipment is not in use, the user can still remotely understand the status of the mechanical equipment and realize remote monitoring of the mechanical equipment.
