[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution 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. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] See below Figure 1 , Figure 1 A flow chart of a control method for engineering machinery provided in an embodiment of the present application.

[0048] Specific steps may include:

[0049] S101: If the power-on position of the one-touch start switch is triggered, continuously outputting a power-on signal to the human-machine interaction device and all the engines;

[0050] Among them, this embodiment can be applied to a controller of an engineering machine, wherein the engineering machine also includes a human-machine interaction device, a one-button start switch and at least two engines, wherein the one-button start switch includes a stop gear, a power-on gear and a start gear. The controller is used to process signals and perform corresponding operations. The human-machine interaction device allows a user to input information. Through the one-button start switch, a user can control any number of engines to complete power-on, start and stop operations, thereby simplifying the operation process.

[0051] When the power-on position of the one-button start switch is triggered, the one-button start switch can send a corresponding signal to the controller so that the controller continuously outputs a power-on signal to the human-machine interaction device and all engines. The operation of continuously outputting a power-on signal means that the controller continuously supplies power to the human-machine interaction device and all engines to keep them activated and in standby state.

[0052] Through the above operation, the human-machine interaction device and all engines can be powered and enter the standby state. Specifically, after receiving the power-on signal, the human-machine interaction device is activated and displays necessary information to be ready to receive further instructions from the user. After receiving the power-on signal, the control systems of all engines are activated to prepare for subsequent starting operations.

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

[0054] When the user inputs the first identification information through the human-machine interaction device (such as a touch screen or a control panel), the controller can record and identify the first identification information. The first identification information can be the identification of the engine to be started (such as a number, name or other unique identifier). The controller can determine which engines need to be started based on the first identification information. Through the above scheme, the user can accurately select the engine to be started, avoid misoperation, and improve the accuracy and efficiency of control. The human-machine interaction device can provide an intuitive interface and feedback to ensure that the user can make a selection easily and accurately.

[0055] S103: Determine whether the start gear of the one-touch start switch is triggered; if so, enter S104; if not, end the process.

[0056] After the start gear 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 gear of the one-button start switch is triggered according to the signal reception; if the start gear of the one-button start switch is triggered, then enter the relevant operation of S104; if the start gear of the one-button start switch is not triggered, then enter the operation of S103 again after a certain delay.

[0057] S104: Sending a start signal to each first-category engine;

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

[0059] After sending the start signal once, the engine corresponding to the first identification information may directly enter the start state, or may fail to start due to a fault. If the engine fails to start, the user can trigger the start position of the one-button start switch again, and at this time, the start signal is only sent to the engine corresponding to the first identification information and not currently in the start state. In this way, it can be ensured that only the specified engine that has not yet started receives the start signal, avoiding repeated starts and misoperation.

[0060] The present embodiment provides a control method for an engineering machine, the engineering machine comprising a controller, a human-machine interaction device, a one-touch start switch and at least two engines. After the power-on position of the one-touch start switch is triggered, the present embodiment continuously outputs a power-on signal to the human-machine interaction device and all the engines, and uses the human-machine interaction device to receive the first identification information input by the user, so as to determine the engine to be started. The present embodiment regards the engine corresponding to the first identification information and not currently in the starting state as the first type of engine. After the starting position of the one-touch start switch is triggered, the present embodiment sends a start signal to each first type of engine, so as to perform the corresponding engine starting operation. The present embodiment uses the one-touch start switch, and the user can easily complete the power-on, start and stop operations without manually operating each engine one by one, thereby simplifying the operation steps. In the above process, the start signal is only sent to the engine corresponding to the first identification information and not currently in the starting state, instead of sending the start signal to all engines corresponding to the first identification information, so as to avoid the situation where the start signal is repeatedly sent. Therefore, the present embodiment can reduce the operation complexity of the engineering machine and improve the control efficiency.

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

[0062] When the user inputs the second identification information through the human-computer interaction device (such as a touch screen or a control panel), the controller can record and identify the second identification information. The second identification information can be the identification (such as a number, name or other unique identifier) ​​of the engine to be shut down. The controller can determine which engines need to be shut down according to the second identification information. Through the above scheme, the user can accurately select the engine that needs to be shut down, avoid misoperation, and improve the accuracy and efficiency of control.

[0063] In this embodiment, the engine can be stopped by stopping sending the power-on signal. When the stop position of the one-button start switch is triggered, the controller stops outputting the power-on signal to the engine corresponding to the second identification information and currently in the start state. In this way, the power supply of the second type of engine is cut off, so that it stops running. In this way, it can be ensured that only the engine specified by the user is stopped, thereby improving the accuracy and safety of the operation.

[0064] As for Figure 1Further introduction to the corresponding embodiment, before stopping outputting 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 coolant temperature and / or speed of the engine; if so, the step of stopping outputting the power-on signal to the second type of engine is entered; if not, corresponding operations (such as reducing the speed or delaying) are performed according to the operating parameters to ensure that the operating parameters of the second type of engine are within the preset range.

[0065] Through the above operation, the second type engine can be shut down after the operating parameters are within the preset range. If there are multiple second type engines, this embodiment can control the corresponding second type engine to shut down when the operating parameters of the second type engine 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 operating parameters of the engine may not be judged, but the output of power-on signals to all engines may be stopped directly.

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

[0068] Starting Motor (also known as starting motor or starter) 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 drive the engine crankshaft to rotate through electrical energy at the initial stage of engine starting, so that the engine reaches a sufficient speed to start.

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

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

[0071] The process described in the above embodiment is explained below through an embodiment in actual application.

[0072] At present, some excavators use large-tonnage twin engines. The start and stop control method adopted by the twin engines is: use two start key switches to control the start and stop of the two engines respectively. When starting, one engine must be started first, and then the other engine. The same is true when stopping. The demand for delayed shutdown of large engines also requires manual engine deceleration and then control of the start key switch to stop the operation, which is not only inconvenient but also has the risk of engine damage due to misoperation.

[0073] In response to the technical problems existing in the above-mentioned related technologies, the present embodiment provides a dual-engine excavator start-stop control system, which can realize the simultaneous start and stop of the dual engines with one button, and can also realize the independent start and stop of any engine. At the same time, it can automatically reduce the speed to a reasonable range when shutting down, determine the delayed shutdown time by itself, and realize automatic delayed shutdown, so as to avoid human error in operation to protect the engine and avoid the operator from waiting too much unnecessary time.

[0074] See also Figure 2 , Figure 2 A schematic diagram of the structure of a dual-engine excavator start-stop control system provided in an embodiment of the present application, showing: a one-button start switch, an emergency stop switch, a controller, an engine 1, an engine 2, an instrument, an engine electronic control unit 1, and an engine electronic control unit 2. The one-button start switch includes a stop gear, a power-on gear, and a start gear. 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. The engine 1 includes a starter motor 1 and an engine electronic control unit 1, and the engine 2 includes a starter motor 2 and an engine electronic control unit 2. The engine electronic control unit 1 includes a power-on signal interface and a bus 1 interface, the engine electronic control unit 2 includes a power-on signal interface and a bus 2 interface, and the instrument includes a power-on signal interface, a bus 1 interface, and a bus 2 interface.

[0075] When the one-button start switch is turned to the upper potential, the controller power-on signal input is energized, the controller outputs power-on signal 1 to the engine electronic control unit 1 to make the electronic control unit 1 enter the working state, outputs power-on signal 2 to the engine electronic control unit 2 to make the electronic control unit 2 enter the working state, outputs power-on signal 3 to the instrument to make the instrument enter the working state, outputs start signal 1 to control the starter motor 1 to start the engine 1, and outputs start signal 2 to control the starter motor 2 to start the engine 2. The controller is connected to the instrument and the engine electronic control unit 1 through bus 1 to communicate information; the controller is connected to the instrument and the engine electronic control unit 2 through bus 2 to communicate information. When the one-button start switch returns to the stop position, the controller power-on signal input is de-energized, the controller power-on signal 1 stops outputting, the engine electronic control unit 1 stops working, and the engine 1 stops working; the controller power-on signal 2 stops outputting, the engine electronic control unit 2 stops working, and the engine 2 stops working; the controller power-on signal 3 stops outputting, and the instrument stops working. When there is an emergency stop signal input, the controller immediately stops power-on signal 1 and power-on signal 2 to stop the engine 1 and the engine 2.

[0076] See also Figure 3 , Figure 3 A schematic diagram of an instrument interface provided in an embodiment of the present application. The default setting for engine start is dual-engine synchronous start and stop. When a single engine start and stop is required, enter the instrument's engine start and stop selection interface to select the engine to be started or stopped. The instrument sends the current selection to the controller via bus 1 or 2. The controller controls the corresponding selected start signal and power-on signal to start and stop the corresponding engine. In the engine start and stop selection interface, the engine start options include engine 1 and engine 2, and the engine stop options include engine 1 and engine 2.

[0077] According to different situations, this embodiment can divide the engine starting into two modes, mode one: dual-engine starting mode, mode two: single-engine starting mode; and divide the engine stopping into two modes, mode one: normal stop mode, mode two: emergency stop mode.

[0078] See also Figure 4 , Figure 4A flowchart of a dual-start mode provided in an embodiment of the present application, the process is as follows: the one-button start switch is switched to the power-on position, the controller outputs power-on signals 1, 2, 3, the instrument and the electronic control unit 1, the electronic control unit 2 enter the working state, press the one-button start switch to the start position, and the control output device starts the signal 1, 2. If both engine 1 and engine 2 start successfully, then the process ends. If both engine 1 and engine 2 fail to start successfully, press the one-button start switch to the start position again to start. If engine 1 starts successfully and engine 2 fails to start successfully, it will prompt: If engine 2 fails to start, please press the start switch again. After pressing the one-button start switch to the start position again, the controller only outputs the start signal 2, and repeats this until engine 2 starts successfully. If engine 2 starts successfully and engine 1 fails to start successfully, it will prompt: If engine 1 fails to start, please press the start switch again. After pressing the one-button start switch to the start position again, the controller only outputs the start signal 1, and repeats this until engine 1 starts successfully.

[0079] See also Figure 5 , Figure 5 A flow chart of a single-engine starting mode provided in an embodiment of the present application, the process of which is as follows: the one-button start switch is switched to the power-on position, the controller outputs power-on signals 1, 2, 3, after the engine to be started is selected on the instrument engine start / stop interface, the instrument sends the selection result to the controller, press the one-button start switch to the start position, at this time the controller only outputs the start signal corresponding to the engine selected on the instrument interface, if the engine starts successfully, it ends, if the start fails, press the one-button start switch again to the start position, and repeat this process until the start is successful.

[0080] See also Figure 6 , Figure 6 A flow chart of a normal shutdown mode provided in an embodiment of the present application, the process is as follows: the one-button start switch is switched to the stop gear, and the controller reads the operating information of engines 1 and 2, such as the water temperature and speed of the engines. If the current operating speed of engines 1 and 2 is higher than the idle speed, the controller sends an instruction to reduce the speed of engines 1 and 2 to the idle speed. If the speed of engines 1 and 2 is at the 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. When 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 to stop the operation of engines 1, 2 and the instrument.

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

[0084] This application adopts a new control system that can realize one-button start and stop, and can also realize the independent start and stop of any engine. At the same time, it can automatically reduce the speed to a reasonable range when shutting down, and automatically determine the delayed shutdown time to realize automatic delayed shutdown, avoiding human error to protect the engine and avoiding too much unnecessary waiting time for the operator. The independent start and stop of the above dual engines can use an external switch to replace the instrument interface; this embodiment can also use a preset time interval gear and other methods to realize delayed shutdown.
