[0031] Figure 3 is a flow chart of a control method for engineering machinery provided by an embodiment of the present invention. The control method can be applied to a communication module of a vehicle-mounted terminal. Figure 3 , the control method may include the following steps:

[0032] Step S110: After the connection with the mobile terminal is successful, the control signal of the mobile terminal for controlling the target engineering machinery is obtained at a preset frequency, and the operation data, working condition data and environmental data of the target engineering machinery are obtained at the same time.

[0033] In a preferred embodiment of the present invention, after acquiring the control signal of the mobile terminal controlling the target engineering machinery, the control method may further include: decrypting the control signal encrypted by the mobile terminal using a preset secret key and a decryption method.

[0034] Please refer to Figure 4 For example, an embodiment of the present invention controls construction machinery (for example, cranes, etc.) through a mobile terminal (for example, a mobile device). In a preferred embodiment, a control program or control software (for example, an APP) can be configured on the mobile device to simulate mechanical controls and control the construction machinery to perform corresponding operations. By way of example, a communication connection can be established between the mobile device APP and the communication module (for example, a WIFI module) on the vehicle-mounted terminal. For example, a local area network is established through a socket mechanism to achieve data communication between the mobile device APP and the WIFI module, and permission verification is performed. After the verification is passed, a communication scenario is established (that is, the connection with the mobile terminal is successful), and a one-time symmetric encryption key and encryption algorithm are obtained, and the control signal is encrypted and transmitted through symmetric encryption.

[0035] Continuing with the above example, when the target engineering machinery starts to run, the operating data, working condition data and environmental data of the target engineering machinery can be obtained in real time through its configured controller, engine and sensor. After successfully connecting to the mobile terminal, the mobile terminal can continuously send instructions to the WIFI module to indicate "no action operation" at a preset frequency (for example, a frequency of 200ms / time). The operating performance of the target engineering machinery controlled by this instruction is, for example: 1) If there is currently an operation (or action), stop the operation (or action); if there is no operation (or action), continue to maintain. When the control signal sent by the operator to control the target engineering machinery through the mobile terminal is obtained, the control information can be decrypted to obtain the decrypted control signal; further, the WIFI module obtains the operating data, working condition data and environmental data of the target engineering machinery in real time.

[0036] Further preferably, for the mobile terminal (preferably equipped with a touch screen key control module), the control method of the touch screen key control module can be configured accordingly according to the actions of the target engineering machinery to perform various operations; the operator's operation on the configured touch screen key control module is obtained, and based on the operation, a corresponding control signal is generated.

[0037] By way of example, the control method of the control button or control switch of the construction machinery can be simulated on the touch screen key control module. For example, when controlling the crane to rotate left, the operator can swipe the screen continuously to the left at the simulated control of the touch screen key control module; according to the operation event, the corresponding control information is generated, and the control signal is continuously sent at a preset frequency.

[0038] Step S120: judging whether the control signal will cause dangerous control by using the acquired operation data, working condition data and environmental data of the target engineering machinery.

[0039] Preferably, step S120 may include: predicting the operation to be performed by the target engineering machinery at the next moment through the acquired operation data, working condition data and environmental data of the target engineering machinery; when the control signal can achieve the predicted operation, determining that the control signal will not cause dangerous control; and otherwise, determining that the control signal will cause dangerous control.

[0040] Following the above example, when the operator operates the touch screen key control module, an operation error may occur, causing the control signal to cause dangerous control; or in the process of sending the control signal, the control signal error may occur due to the weak network signal; or in the operation of the engineering machinery, an emergency may cause danger, and the operator does not perform the corresponding control in time, causing the engineering machinery to be dangerous. In this regard, the WIFI module can predict the operation to be performed by the target engineering machinery at the next moment through the acquired operation data, working condition data and environmental data of the target engineering machinery; when the control signal can achieve the predicted operation, it is determined that the control signal will not cause dangerous control; otherwise, it is determined that the control signal will cause dangerous control. For example, in the process of controlling the crane to move forward, the acquired control signal instructs the crane to move to the left, and through the operation data, working condition data and environmental data of the crane, it is predicted that the crane should continue to move forward at the next moment, and at this time it is determined that the current control signal causes dangerous control.

[0041] Step S130: When the control signal will not cause dangerous control, the target engineering machine is controlled to perform corresponding operations through the control signal.

[0042] Please refer to Figure 4 , following the above example, the operator sets the control signal as "engine speed 1000, slewing speed 80%, slewing direction left, action type slewing combination instruction" through the mobile device APP. After the WIFI module obtains the encrypted control signal and determines that the changed control signal will not cause dangerous control, the WiFi module can decrypt the control signal and convert it into a CAN signal, and transmit the corresponding parameters to the crane controller (i.e., local controller) through the CAN bus. The crane controller transmits the operation indicated by the control signal to, for example, the slewing action controller and the engine controller.

[0043] Step S140: When the control signal may cause dangerous control, the control signal is corrected, and the target engineering machine is controlled to perform corresponding operations through the corrected control signal.

[0044] Please refer to Figure 4 , following the above example, the operator sets the control signal through the mobile device APP to "engine speed is 1000, slewing speed is 80%, slewing direction is left, and action type is slewing combination instruction". The WIFI module obtains the encrypted control signal. If it is determined that the control signal will cause dangerous control based on the acquired operating data, working condition data and environmental data of the target engineering machinery (for example, there are obstacles on the left, etc.), the WIFI module can correct the control signal, for example, to control the crane to perform a no-action operation. The WiFi module can convert the corrected control signal into a CAN signal, and transmit the corresponding parameters to the crane controller through the CAN bus. The crane controller operates according to the control signal.

[0045] Preferably, after step S130 or S140, the control method may further include: encrypting the status information of the target engineering machinery performing the operation by using a preset key and encryption method; and sending the encrypted status information to the mobile terminal.

[0046] Continuing with the above example, when the control signal will not cause dangerous control, the engine controller obtains the status information of the target engineering machinery executing the operation, that is, the engine speed and the current rotation angle of the current vehicle; the status information is transmitted to the local controller through the CAN bus, and the local controller transmits the parameters to the mobile device APP through the WIFI module in the same encryption method. The mobile device APP decrypts the data into the corresponding parameter value and displays it on the interface; after the mobile device determines that the real-time changing rotation angle value reaches the expected value, it stops operating the APP. When the control signal will cause dangerous control, the operation control indicated by the corrected control signal is sent to the mobile device APP to notify the operator to solve it.

[0047] In a preferred embodiment of the present invention, the control method may further include: when the control signal is not received for more than a first preset time, controlling the target engineering machinery to perform a no-action operation; and when the control signal is not received for more than a second preset time, controlling the target engineering machinery to perform an emergency stop operation.

[0048] To illustrate by way of example, in the process of controlling construction machinery through the mobile device APP-WIFI module, if the network anomaly causes the signal to be intermittent, the WIFI module can judge based on the interval between the control signals. For example, if the next control signal is not received after a first preset time (for example, 400ms), the WIFI module can send a control signal indicating "no action operation" to the construction machinery. Until the next control signal sent by the mobile device APP is received or the preset time (for example, 30s) is continuously sent. If the control signal is not received after a second preset time (for example, 800ms), the emergency stop operation of the device will be triggered, and all actions will be stopped.

[0049] Accordingly, the communication module of the vehicle-mounted section of the embodiment of the present invention, after successfully connecting with the mobile terminal, obtains the control signal of the mobile terminal to control the target engineering machinery at a preset frequency, and obtains the operation data, working condition data and environmental data of the target engineering machinery at the same time; through the operation data, working condition data and environmental data of the target engineering machinery obtained, it is judged whether the control signal will cause dangerous control; when the control signal will not cause dangerous control, the target engineering machinery is controlled to perform corresponding operations through the control signal; and when the control signal will cause dangerous control, the control signal is corrected, and the target engineering machinery is controlled to perform corresponding operations through the corrected control signal. For engineering machinery and new energy engineering machinery, the control method based on the architecture of mobile device APP-WIFI module-vehicle-mounted controller of the embodiment of the present invention is more convenient to use, with a longer transmission distance, faster speed and more stable system; in terms of control function expansion, the upgrade and iteration speed is fast; based on the communication module, the control signal of the mobile terminal is corrected and corrected, which can improve the safety of engineering machinery and new energy engineering machinery; further, the interactive rule of continuously sending signals is used to effectively avoid the problem of equipment action being unable to stop due to untimely instruction sending. The embodiment of the present invention utilizes a mobile device APP to ensure that wireless remote control communication is both safe and efficient through a dynamically encrypted communication method.

[0050] Figure 5 is a flow chart of another control method for engineering machinery provided by an embodiment of the present invention. The control method is applied to a mobile terminal, and the mobile terminal is equipped with a touch screen key control module. Figure 5 , the control method may include the following steps:

[0051] Step S210: According to the actions of the target engineering machinery to perform various operations, the control mode of the touch screen key control module is correspondingly configured.

[0052] In a preferred embodiment of the present invention, when the control mode of the corresponding configuration of the touch screen key control module is a long press mode, the control method may further include: when a long press event is detected and the long press event lasts for a preset time, generating the corresponding control signal; and when a release event is detected, the touch screen key control module returns to an initial state.

[0053] Please refer to Figure 4 , by way of example, the embodiment of the present invention controls construction machinery (e.g., cranes, etc.) through a mobile terminal (e.g., a mobile device). In a preferred embodiment, a control program or control software (e.g., an APP) can be configured on the mobile device to simulate a mechanical control to control the construction machinery to perform corresponding operations. Operations involving control actions must be perceptible, not prone to accidental touches, and can clearly distinguish between long presses and taps. This allows the operator to have a clear understanding of the instructions he or she has issued, avoiding safety accidents caused by accidental touches or mis-issued instructions. In the configuration of the touch screen key control module, it is preferred to use a sliding form to trigger, which can avoid accidental touches caused by rain, putting it in a pocket, etc. When sliding starts, it can be accompanied by the vibration of the mobile device itself, so that it can be well sensed whether the operation has started. At the same time, the sliding button requires the operator's finger to be pressed on the screen to continue to take effect. Once released, the simulated button will automatically return to its original position, and combined with continuous vibration, the operator can clearly know whether it is currently in a "long press" state.

[0054] Step S220: According to the restrictions on the target engineering machinery to perform various operations, the control restrictions of the touch screen key control module are configured accordingly.

[0055] By way of example, the control signal can be restricted on the mobile terminal by configuring the APP touch screen key control module (multiple simulated buttons, simulated keys or simulated control areas, etc.) to reduce dangerous control. For example, when the operator drags the rotary button and gradually slides it to the "left", the corresponding percentage value is obtained by comparing the amount of the button shifted to the "left" with the total amount that can be shifted; if the value does not exceed the preset threshold (for example, 10%), the operation is considered to be an erroneous operation and will be ignored; when the value exceeds "10%", the next step is entered.

[0056] Step S230: After the communication module of the vehicle-mounted end is successfully connected, the operator's operation on the configured touch screen key control module is obtained, and a corresponding control signal is generated according to the operation.

[0057] Following the above example, after successfully connecting to the communication module (e.g., WIFI module) on the vehicle side, the mobile terminal can continuously send instructions to the WIFI module at a preset frequency (e.g., a frequency of 200ms / time) to indicate "no action operation". The operation performance of the target engineering machinery controlled by this instruction is, for example: 1) If there is currently an operation (or action), stop the operation (or action); if there is no operation (or action), continue to maintain. When the operator drags the rotary button, for example, and gradually slides to the "left" direction, if the operator drags the rotary button to a position of, for example, 80% offset at this time, the APP will generate a corresponding control signal for the current state "rotation speed is 80%, rotation direction is left, and action type is rotation".

[0058] Preferably, after step S230, the control method may further include: encrypting the control signal by using a preset key and encryption method.

[0059] Step S240: sending the control signal at a preset frequency to control the target engineering machine to perform corresponding operations.

[0060] Continuing with the above example, the APP can continuously send the control signal to the WIFI module at a preset frequency (for example, a frequency of 200ms / time); if the operator stops operating on the APP (for example, releasing his finger), the analog button will automatically return to the default state. At this time, the continuously sent control signal is restored to the "no action operation" instruction; if the operator encounters an abnormal signal during the operation, the APP will detect the current signal, for example, after it is lower than a preset higher packet loss rate value, for example, a prompt box will pop up on the touch screen key control module of the APP, saying "The current network environment is poor. To ensure the safety of equipment and personnel, please do not proceed"; at the same time, the action button will be forced to return to the default state and start sending the "no action operation" instruction.

[0061] Following the above example, when the operator operates the touch screen key control module, an operation error may occur, causing the control signal to cause dangerous control; or in the process of sending the control signal, the control signal error may occur due to the weak network signal; or in the operation of the engineering machinery, an emergency may cause danger, and the operator does not perform the corresponding control in time, causing the engineering machinery to be dangerous. In this regard, the WIFI module can predict the operation to be performed by the target engineering machinery at the next moment through the acquired operation data, working condition data and environmental data of the target engineering machinery; when the control signal can achieve the predicted operation, it is determined that the control signal will not cause dangerous control; otherwise, it is determined that the control signal will cause dangerous control. For example, in the process of controlling the crane to move forward, the acquired control signal instructs the crane to move to the left, and through the operation data, working condition data and environmental data of the crane, it is predicted that the crane should continue to move forward at the next moment, and at this time it is determined that the current control signal causes dangerous control.

[0062] Preferably, after step S240, the control method may further include: obtaining encrypted status information of the target engineering machinery performing corresponding operations; decrypting the status information using a preset key and decryption method; and adaptively adjusting the touch screen key control module according to the decrypted status information.

[0063] Continuing with the above example, when the control signal will not cause dangerous control, the engine controller obtains the status information of the target engineering machinery executing the operation, that is, the engine speed and the current rotation angle of the current vehicle; the status information is transmitted to the local controller through the CAN bus, and the local controller transmits the parameters to the mobile device APP through the WIFI module in the same encryption method. The mobile device APP decrypts the data into the corresponding parameter value and displays it on the interface; after the mobile device determines that the real-time changing rotation angle value reaches the expected value, it stops operating the APP. When the control signal will cause dangerous control, the operation control indicated by the corrected control signal is sent to the mobile device APP to notify the operator to solve it.

[0064] Accordingly, the embodiment of the present invention is based on the touch screen key control module configured by the mobile terminal, and according to the actions of the target engineering machinery to perform various operations, the control mode of the touch screen key control module is configured accordingly; according to the restrictions on the target engineering machinery to perform various operations, the control restrictions of the touch screen key control module are configured accordingly; and after the communication module of the vehicle-mounted terminal is successfully connected, the operator's operation on the configured touch screen key control module is obtained, and according to the operation, a corresponding control signal is generated; and the control signal is sent at a preset frequency to control the target engineering machinery to perform the corresponding operation. The embodiment of the present invention configures the interactive design for the mobile terminal (mobile device APP), makes up for the shortcomings of virtual buttons such as "no perception", "easy to touch by mistake" and "long press is unfriendly", breaks the limitation that the remote control can only use physical buttons and physical remote controls for operation, and redefines the auxiliary operation control remote control of engineering machinery. In the configuration of the mobile device APP, the advantages and advantages of the virtual remote control software itself are further magnified from the aspects of convenience, reusability, reliability and performance. Furthermore, the virtual remote control replaces the physical remote control to bring a more humane and efficient user experience for engineering machinery to obtain auxiliary operation control operations.
