[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Please see below. Figure 1 , Figure 1 This is a flowchart illustrating a control method for engineering machinery provided in an embodiment of this application.

[0048] Specific steps may include:

[0049] S101: If the power-on position of the one-button start switch is triggered, a power-on signal is continuously output to the human-machine interface device and all the engines.

[0050] This embodiment can be applied to a controller for construction machinery, which also includes a human-machine interface device, a one-button start switch, and at least two engines. The one-button start switch includes a stop position, a power-on position, and a start position. The controller processes signals and executes corresponding operations. The human-machine interface device allows users to input information. Through the one-button start switch, users can control any number of engines to complete power-on, start, and stop operations, simplifying the operation process.

[0051] When the one-button start switch is activated, it sends a signal to the controller, causing the controller to continuously output a power-on signal to the human-machine interface and all engines. Continuous power-on signal output means that the controller continuously supplies power to the human-machine interface and all engines, keeping them active and in standby mode.

[0052] Through the above operations, power can be supplied to the human-machine interface and all engines, putting them into standby mode. Specifically, upon receiving a power-on signal, the human-machine interface is activated and displays necessary information to prepare for receiving further user commands. Upon receiving a power-on signal, the control systems of all engines are activated, preparing for subsequent starting operations.

[0053] S102: Receive the first identification information input by the user using the human-computer interaction device;

[0054] When a user inputs first identification information via a human-machine interface (such as a touchscreen or control panel), the controller can record and recognize this information. The first identification information can be an identifier of the engine to be started (such as a serial number, name, or other unique identifier). The controller can determine which engines need to be started based on this first identification information. This approach allows users to accurately select the engines to be started, avoiding misoperation and improving control accuracy and efficiency. The human-machine interface provides an intuitive interface and feedback, ensuring users can make selections easily and accurately.

[0055] S103: Determine whether the start position of the one-button start switch has been triggered; if yes, proceed to S104; if no, end the process.

[0056] When the start position of the one-button start switch is triggered, the one-button start switch can send a corresponding signal to the controller. The controller can determine whether the start position of the one-button start switch has been triggered based on the received signal; if the start position of the one-button start switch has been triggered, the relevant operation in S104 is entered; if the start position of the one-button start switch has not been triggered, the operation in S103 can be entered again after a certain delay.

[0057] S104: Send a start signal to each of the first-class engines;

[0058] In this embodiment, the engine corresponding to the first identification information and currently not in the starting state is designated as the first type of engine. Each time the starting gear is triggered, a starting signal is sent to the first type of engine corresponding to the first identification information and currently not in the starting state.

[0059] After a single start signal is sent, the engine corresponding to the first identification information may directly enter the start state, or it may fail to start due to a malfunction. If the engine fails to start, the user can trigger the start position of the one-button start switch again. In this case, a start signal is only sent to the engine corresponding to the first identification information that is not currently in the start state. This method ensures that only the designated, unstarted engine receives the start signal, avoiding repeated starts and misoperations.

[0060] This embodiment provides a control method for construction machinery, which includes a controller, a human-machine interface device, a one-button start switch, and at least two engines. After the one-button start switch is activated, this embodiment continuously outputs a power-on signal to the human-machine interface device and all the engines, and uses the human-machine interface device to receive first identification information input by the user to determine the engines to be started. This embodiment designates engines corresponding to the first identification information and currently not in a running state as a first category of engines. After the one-button start switch is activated, this embodiment sends a start signal to each first category of engines to execute the corresponding engine start operation. Through the one-button start switch, this embodiment allows users to easily complete power-on, start, and stop operations without manually operating each engine individually, simplifying the operation process. In the above process, only the engines corresponding to the first identification information and currently not in a running state are sent start signals, instead of sending start signals to all engines corresponding to the first identification information, thus avoiding the repeated transmission of start signals. Therefore, this embodiment can reduce the operational complexity of construction machinery and improve control efficiency.

[0061] As a feasible implementation method, this embodiment can also control the engine to stop in the following way: receiving the second identification information input by the user using the human-machine interaction device; wherein, the second identification information is the identification of the engine to be stopped; determining whether the stop position of the one-button start switch is triggered; if so, stopping the output of the power-on signal to the second type of engine; wherein, the second type of engine is the engine corresponding to the second identification information and currently in the starting state.

[0062] When a user inputs second identification information via a human-machine interface (such as a touchscreen or control panel), the controller can record and recognize this information. The second identification information can be an identifier of the engine to be shut down (such as its serial number, name, or other unique identifier). The controller can determine which engines need to be shut down based on this second identification information. This approach allows users to accurately select the engines that need to be shut down, avoiding misoperation and improving the accuracy and efficiency of control.

[0063] This embodiment achieves engine shutdown by stopping the transmission of power-on signals. When the shutdown position of the one-button start switch is triggered, the controller stops outputting power-on signals to the engine corresponding to the second identification information and currently in the start state. This method cuts off the power supply to the second type of engine, causing it to stop operating. This method ensures that only the user-specified engine is shut down, improving operational accuracy and safety.

[0064] As for Figure 1In a further description of the corresponding embodiment, before stopping the output of the power-on signal to the second type of engine, it can be determined whether the operating parameters of the second type of engine are within a preset range; wherein, the operating parameters include the engine's coolant temperature and / or speed; if yes, then proceed to the step of stopping the output of the power-on signal to the second type of engine; if no, then perform the corresponding operation (such as reducing the speed or delaying) according to the operating parameters, so that the operating parameters of the second type of engine are within the preset range.

[0065] Through the above operations, the second type of engine can be shut down only after its operating parameters are within a preset range. If there are multiple second type engines, this embodiment can control the corresponding second type engine to shut down when its operating parameters are within the preset range.

[0066] As for Figure 1 As further described in the corresponding embodiment, if an emergency stop signal is received, the engine's operating parameters can be disregarded, and the power-on signal to all engines can be directly stopped.

[0067] As for Figure 1 As further described in the corresponding embodiment, the engine includes a starting motor and an electronic control unit (ECU). Accordingly, the operation of continuously outputting a power-on signal to all the engines in the above embodiment can be: continuously outputting a power-on signal to the ECU of all the engines; accordingly, the operation of sending a starting signal to each of the first type of engines in the above embodiment can be: sending a starting signal to the starting motor of each of the first type of engines.

[0068] A starting motor is an electric motor used to provide the necessary rotational torque when starting an internal combustion engine. The main function of the starting motor is to use electrical energy to drive the engine crankshaft to rotate during the initial stages of engine startup, enabling the engine to reach sufficient speed for starting.

[0069] As for Figure 1 As further described in the corresponding embodiment, the controller can receive engine status information transmitted by the electronic control unit and display the engine status information through a human-machine interaction device.

[0070] As for Figure 1In a further description of the corresponding embodiment, this embodiment can start all engines by default. If the first identification information input by the user is not received, and the start position of the one-button start switch is triggered, a start signal is sent to all engines. This embodiment can also shut down all engines by default. If the second identification information input by the user is not received, and the stop position of the one-button start switch is triggered, the power-on signal to all engines is stopped.

[0071] The process described in the above embodiments is illustrated below through examples in practical applications.

[0072] Currently, some excavators use large-tonnage dual engines. The start-stop control method for dual engines is as follows: two starter keys are used to control the start and stop of the two engines respectively. When starting, one engine must be started first, and then the other engine is started. The same applies when stopping. Furthermore, the requirement for delayed engine shutdown of large engines also requires manually slowing down the engine before controlling the starter key to stop it. This is inconvenient and carries the risk of engine damage due to misoperation.

[0073] To address the technical problems existing in the aforementioned related technologies, this embodiment provides a start-stop control system for a dual-engine excavator. This system can realize simultaneous start-stop of both engines with one button, or individual start-stop of any engine. At the same time, it can automatically reduce the speed to a reasonable range when stopping the machine, automatically determine the delay shutdown time, and realize automatic delay shutdown to avoid human error, protect the engine, and avoid excessive unnecessary waiting time for the operator.

[0074] Please see Figure 2 , Figure 2 This is a schematic diagram of a dual-engine excavator start-stop control system provided in an embodiment of this application. The diagram shows: a one-button start switch, an emergency stop switch, a controller, engine 1, engine 2, instruments, engine electronic control unit 1, and engine electronic control unit 2. The one-button start switch includes a stop position, a power-on position, and a start position. The controller may include an emergency stop signal interface, a power-on signal interface, a start signal interface, a bus 1 interface, a bus 2 interface, a power-on signal 1 interface, a power-on signal 2 interface, a power-on signal 3 interface, a start signal 1 interface, and a start signal 2 interface. Engine 1 includes a starter motor 1 and engine electronic control unit 1, and engine 2 includes a starter motor 2 and engine electronic control unit 2. Engine electronic control unit 1 includes a power-on signal interface and a bus 1 interface, engine electronic control unit 2 includes a power-on signal interface and a bus 2 interface, and the instruments include a power-on signal interface, a bus 1 interface, and a bus 2 interface.

[0075] When the one-button start switch is turned up to the high position, the controller receives a power-on signal. The controller outputs power-on signal 1 to engine control unit 1, power-on signal 2 to engine control unit 2, and power-on signal 3 to the instrument cluster. It also outputs start signal 1 to control starter motor 1 and starter signal 2 to control starter motor 2. The controller communicates with the instrument cluster and engine control unit 1 via bus 1 and bus 2. When the one-button start switch returns to the stop position, the controller receives no power. Power-on signal 1 stops outputting, engine control unit 1 stops operating, and engine 1 stops operating. Power-on signal 2 stops outputting, engine control unit 2 stops operating, and engine 2 stops operating. Power-on signal 3 stops outputting, and the instrument cluster stops operating. When an emergency stop signal is input, the controller immediately stops power-on signals 1 and 2, causing engines 1 and 2 to stop running.

[0076] Please see Figure 3 , Figure 3 This is a schematic diagram of an instrument panel interface provided in an embodiment of this application. Engine starting defaults to simultaneous start and stop of both engines. When single-engine start and stop are required, the user enters the engine start / stop selection interface of the instrument panel and selects the engine to be started or stopped. The instrument panel sends the current selection to the controller via bus 1 or 2. The controller controls the corresponding start signal and power-on signal to start and stop the corresponding engine. In the engine start / stop selection interface, the engine start options include engine 1 and engine 2, and the engine stop options also include engine 1 and engine 2.

[0077] Depending on the circumstances, this embodiment can divide engine starting into two modes: Mode 1: dual-start mode and Mode 2: single-start mode; and engine stopping into two modes: Mode 1: normal shutdown mode and Mode 2: emergency shutdown mode.

[0078] Please see Figure 4 , Figure 4The flowchart of a dual-start mode provided in this application embodiment is as follows: The one-button start switch is switched to the power-on position, the controller outputs power-on signals 1, 2, and 3, and the instrument cluster, electronic control unit 1, and electronic control unit 2 enter the working state. The one-button start switch is pressed to the start position, and the controller outputs start signals 1 and 2. If both engines 1 and 2 start successfully, the process ends. If neither engine 1 nor 2 starts successfully, the one-button start switch is pressed to the start position again to attempt to start. If engine 1 starts successfully but engine 2 fails to start, a message is displayed: "Engine 2 failed to start. Please press the start switch again." After pressing the one-button start switch to the start position again, the controller only outputs start signal 2, and this process repeats until engine 2 starts successfully. If engine 2 starts successfully but engine 1 fails to start, a message is displayed: "Engine 1 failed to start. Please press the start switch again." After pressing the one-button start switch to the start position again, the controller only outputs start signal 1, and this process repeats until engine 1 starts successfully.

[0079] Please see Figure 5 , Figure 5 The flowchart of a single-start mode provided in this application embodiment is as follows: the one-button start switch is switched to the power-on position, the controller outputs power-on signals 1, 2, and 3. After selecting the engine to be started on the instrument panel's engine start / stop interface, the instrument panel sends the selection result to the controller. The one-button start switch is pressed to the start position. At this time, the controller only outputs the start signal corresponding to the engine selected on the instrument panel interface. If the engine starts successfully, the process ends. If the start fails, the one-button start switch is pressed to the start position again, and this process is repeated until the start is successful.

[0080] Please see Figure 6 , Figure 6 The flowchart of a normal shutdown mode provided in this application embodiment is as follows: The one-button start switch is switched to the stop position. The controller reads the operating information of engines 1 and 2, such as engine water temperature and speed. If the current operating speed of engines 1 and 2 is higher than the idle speed, the controller sends a command to reduce the speed of engines 1 and 2 to the idle speed. If the speed of engines 1 and 2 is at idle speed; if the water temperature of engines 1 and 2 is higher than the preset value, the running state of engines 1 and 2 is maintained until the water temperature is lower than the preset value. Once the water temperature of engines 1 and 2 is lower than the preset value, the controller stops outputting power-on signals 1, 2, and 3, so that engines 1 and 2 and instruments all stop running.

[0081] In emergency stop mode, if the controller receives an emergency stop signal from the emergency stop switch while the engine is running, the controller will immediately stop the output of power-on signals 1 and 2 and stop the engine from running.

[0082] Please see Figure 7 , Figure 7This is a schematic diagram of another dual-engine excavator start-stop control system provided in an embodiment of this application. The diagram shows a battery pack, a one-button start switch S1, an emergency stop switch S2, a safety bar switch S3, a controller C (i.e., the whole machine controller), a start relay K1, a start relay K2, a starter motor MA, a starter motor MB, a display D, an engine electronic control unit A, an engine electronic control unit B, and a CAN (Controller Area Network) bus.

In engine control unit A, 410 represents the bus signal interface, 411 represents the power-on signal interface, 412 represents the power interface, and 413 represents the ground interface. In engine control unit B, 510 represents the bus signal interface, 511 represents the power-on signal interface, 512 represents the power interface, and 513 represents the ground interface. In this embodiment, by setting the engine to be started or stopped on the display, the function of starting and stopping one engine individually is achieved.

[0084] This application employs a novel control system that enables one-button start / stop, as well as individual start / stop of either engine. Simultaneously, it automatically reduces the engine speed to a reasonable range during shutdown, automatically determines the delay time for engine shutdown, and achieves automatic delayed shutdown to prevent human error, protect the engine, and avoid excessive unnecessary waiting time for the operator. The individual start / stop of the two engines can be achieved using an external switch instead of an instrument panel; this embodiment can also use preset time interval settings to achieve delayed shutdown.
