[0090] Please refer to Figure 1 , Figure 1 is a structure schematic view of an active safety control system based on panoramic monitoring disclosed by the embodiment of the application. Wherein, Figure 1 The active safety control system based on panoramic monitoring described can be applied to engineering machinery, and can also be applied to a control system corresponding to the engineering machinery, and the embodiment of the application does not make a limitation; further, the system can be applied to a working scene of the engineering machinery, and the embodiment of the application does not make a limitation. As shown in the figure, Figure 1 The active safety control system based on panoramic monitoring can include a panoramic monitoring module 101, a main controller 102, a display 103, an alarm module 104 and a pilot switch module 105, wherein,
[0091] The panoramic monitoring module 101 is used for monitoring an active safety monitoring area corresponding to the engineering machinery to obtain a safety monitoring result when the main controller 102 detects that the panoramic monitoring module 101 meets a pre-set monitoring condition; the active safety monitoring area includes a first area and a second area;
[0092] The panoramic monitoring module 101 is further used for detecting whether the safety monitoring result meets a pre-set safety control condition; when it is detected that the safety monitoring result meets the safety control condition, the panoramic monitoring module 101 sends alarm information corresponding to the safety monitoring result to the main controller 102;
[0093] The main controller 102 is used for controlling a target module corresponding to the alarm information to perform an alarm braking operation according to the received alarm information; the target module includes at least one of the display 103, the alarm module 104 and the pilot switch module 105.
[0094] Optionally, the first region can be a deceleration region, and the second region can be a stopping region; this embodiment of the invention does not impose limitations. Further, the active safety monitoring region can be a region centered on the construction machinery, with a first length as its radius, serving as the deceleration region, and a region with a second length as its radius, serving as the stopping region, where the first length is greater than the second length; this embodiment of the invention does not impose limitations. For an example, please refer to [link to example]. Figure 3 , Figure 3 This is a schematic diagram of the range of an active safety monitoring area disclosed in an embodiment of the present invention, wherein, as shown... Figure 3 As shown, located Figure 3 The center is a type of engineering machinery, and the first area is a deceleration area and the second area is a stopping area. This embodiment of the invention is not limited to this.
[0095] Optionally, the panoramic monitoring module 101 can send alarm information to the main controller 102 via the CAN (Controller Area Network) channel, which is not limited in this embodiment of the invention.
[0096] As can be seen, the system described in the embodiments of the present invention can monitor the active safety monitoring area corresponding to the construction machinery through the panoramic monitoring module when it detects that the panoramic monitoring module meets the preset monitoring conditions, and obtain the safety monitoring results. If the safety monitoring results meet the preset safety control conditions, the system sends the corresponding alarm information to the main controller, and then the main controller controls the target module corresponding to the alarm information to perform alarm braking operation. This achieves intelligent active safety control when a safety risk is detected, without requiring the driver to make a human judgment on the safety of the driving environment or to manually perform the braking operation of the entire machine. This can improve the accuracy and efficiency of risk detection in the working environment of construction machinery, while also improving the timeliness and accuracy of active safety control of construction machinery, thereby reducing the risk of safety accidents during the operation of construction machinery and thus improving the operational safety of construction machinery.
[0097] In an optional embodiment, the display 103 is used to detect whether there is a restriction release command triggered by the driver of the construction machinery, obtain the command detection result, and send the command detection result to the main controller 102; the restriction release command is used to release the safety restriction function of the panoramic monitoring module 101.
[0098] The main controller 102 is also used to determine that the panoramic monitoring module 101 meets the preset monitoring conditions when the instruction detection result indicates that there is no restriction release instruction triggered by the driver corresponding to the construction machinery.
[0099] The main controller 102 is further configured to determine whether the pilot switch module 105 is in a locked state when the instruction detection result indicates that there is a limit release instruction triggered by the driver of the engineering machine; and release the safety limit function of the panoramic monitoring module 101 and determine that the panoramic monitoring module 101 does not meet the preset monitoring condition when it is determined that the pilot switch module 105 is in the locked state.

[0102] Optionally, when the pilot switch module 105 includes a pilot cut-off valve switch, if the pilot cut-off valve switch is in a horizontal state, the pilot cut-off valve switch is in an unlocked state, and if the pilot cut-off valve switch is in a vertical state, the pilot cut-off valve switch is in a locked state, which is not limited in the embodiments of the present application; further optionally, the pilot cut-off valve switch can be controlled by the driver, which is not limited in the embodiments of the present application.
[0103] It can be seen that the optional embodiment can detect whether there is a limit release instruction triggered by the driver through the display, if there is no limit release instruction, it is determined that the panoramic monitoring module meets the preset monitoring condition, that is, the active safety control function can be started to monitor the active safety monitoring area, if there is the limit release instruction, it is further determined whether the pilot switch module is in the locked state, if yes, it is determined that the panoramic monitoring module does not meet the monitoring condition, that is, the active safety control function is not started, which can improve the accuracy of determining whether the panoramic monitoring module meets the monitoring condition, thereby facilitating the intelligent determination of the starting condition of the active safety control function, improving the starting accuracy and flexibility of the active safety control function of the engineering machine, and further facilitating the improvement of the execution accuracy of the monitoring operation and the alarm operation of the panoramic monitoring module, and further facilitating the improvement of the operation safety of the engineering machine.
[0104] In the optional embodiment, as shown in Figure 2 The panoramic monitoring module 101 can include a camera unit 1011 and an AVM (Around View Monitor) host 1012, wherein:
[0105] The camera unit 1011 is configured to monitor a corresponding active safety monitoring area of the engineering machinery, obtain a safety monitoring result, and transmit the safety monitoring result to the AVM host 1012. The safety monitoring result includes safety monitoring video data and / or safety monitoring image data.
[0106] The AVM host 1012 is configured to transmit the safety monitoring result to the display 103, so as to display the safety monitoring result on the display 103.

[0108] It can be seen that the optional embodiment can also realize monitoring of the environment around the engineering machinery through the panoramic monitoring module composed of the camera unit and the AVM host, so as to provide comprehensive and real-time monitoring data to the driver on the display, which is beneficial to improving the convenience and comprehensiveness of the driver in observing the environment around the engineering machinery during the operation of the engineering machinery, and is beneficial to improving the accuracy of judging whether the safety monitoring result meets the safety control condition, and thus is beneficial to improving the accuracy of the active safety control of the engineering machinery.
[0109] In the optional embodiment, the specific manner in which the panoramic monitoring module 101 detects whether the safety monitoring result meets the pre-set safety control condition includes:
[0110] The AVM host 1012 detects, according to the safety monitoring result, whether there is an external object in the active safety monitoring area of the engineering machinery.
[0111] The AVM host 1012 determines that the safety monitoring result meets the pre-set safety control condition when it is detected that there is an external object in the active safety monitoring area of the engineering machinery.
[0112] The AVM host 1012 determines that the safety monitoring result does not meet the pre-set safety control condition when it is detected that there is no external object in the active safety monitoring area of the engineering machinery.
[0113] It can be seen that the optional embodiment can also determine whether the external object is in the active safety monitoring area by the AVM host, and if it is detected that the external object enters the active safety monitoring area, it is determined that the safety monitoring result meets the safety control condition, that is, the active safety control function needs to be executed, otherwise, it is determined that the safety monitoring result does not meet the safety control condition, which can improve the detection accuracy of the external object entering the active safety monitoring area, thereby improving the judgment accuracy of whether the safety monitoring result meets the safety control condition, and further reducing the risk of collision between the engineering machinery and the external object during the operation process.
[0114] For example, the external object can be one of a motor vehicle, a non-motor vehicle, a pedestrian, and an animal, or other movable objects, and the embodiments of the present application are not limited thereto.

[0120] The danger level corresponding to the first alarm level is lower than the danger level corresponding to the second alarm level.
[0121] Among them, exemplary, the first alarm level can be yellow alarm level, the first alarm code can be yellow alarm code, the second alarm level can be red alarm level, the second alarm code can be red alarm code, and the first alarm position or the second alarm position can be used to represent the position of the external object, and the embodiments of the application are not limited.
[0122] It can be seen that the optional embodiment can further divide different alarm levels and other specific alarm information contents for the external object entering different monitoring areas, which is beneficial for the driver and the main controller to more accurately obtain the alarm information, thereby improving the alarm accuracy of the active safety control function, and further improving the active safety control accuracy of the engineering machinery.
[0123] In the optional embodiment, optionally, the main controller 102 controls the specific manner of the target module corresponding to the received alarm information to perform the alarm braking operation, which can include:
[0124] The main controller 102 outputs the received alarm information to the display 103 and the alarm module 104 respectively, to control the display 103 to perform internal alarm operation corresponding to the alarm information and control the alarm module 104 to perform external alarm operation corresponding to the alarm information; the internal alarm operation includes warning visualization operation and internal sound alarm operation for the alarm information; the external alarm operation includes external sound and light alarm operation for the alarm information;
[0125] When the alarm information includes the first alarm information, the main controller 102 controls the engineering machinery to perform the deceleration operation;
[0126] When the alarm information includes the second alarm information, the main controller 102 controls the pilot switch module 105 to perform the path disconnecting operation, to control the engineering machinery to stop operation.
[0127] Among them, optionally, the warning visualization operation can be to display the visualization alarm information (such as: text alarm information, graphical alarm information) corresponding to the alarm information on the display 103, and the internal sound alarm operation can be to output the sound alarm information corresponding to the alarm information through the buzzer of the display 103.
[0128] It can be seen that the optional embodiment can also control the display and the alarm module to perform the internal alarm operation and the external alarm operation corresponding to the alarm information through the main controller, can improve the alarm flexibility and comprehensiveness of the active safety control function, so as to facilitate the driver and the external object to know the current safety risk situation in time, facilitate the external object to leave the working influence range of the construction machinery in time, and reduce the risk of safety accidents of the construction machinery in the working process; and when the alarm information includes the first alarm information, the construction machinery is controlled to slow down, and when the alarm information includes the second alarm information, the construction machinery is controlled to stop, which can improve the flexibility of the braking operation when the external object enters different areas, is conducive to improving the control accuracy of the working operation of the construction machinery, and further improves the accuracy of the active safety control of the construction machinery, and further reduces the risk of safety accidents of the construction machinery in the working process.
[0129] In the optional embodiment, as shown in Figure 2 The alarm module 103 can include the alarm 1041 and the warning light 1042.
[0130] Optionally, the main controller 102 outputs the received alarm information to the display 103 and the alarm module 104 respectively, so as to control the display 103 to perform the internal alarm operation corresponding to the alarm information and control the alarm module 104 to perform the external alarm operation corresponding to the alarm information, which can include the following operations:
[0131] The main controller 102 transmits the alarm code to the display 103 through the CAN channel, so as to display the visual alarm information corresponding to the alarm code on the display 103 and output the sound alarm information through the buzzer of the display 103;
[0132] The main controller 102 outputs a high-level signal to the alarm 1041 and the warning light 1042 respectively, so as to control the alarm 1041 and the warning light 1042 to perform the external sound and light alarm operation.
[0133] For example, when the alarm information includes the first alarm information, the content represented by the visual alarm information and the sound alarm information can be "pay attention to pedestrians, the machine has slowed down"; when the alarm information includes the second alarm information, the content represented by the visual alarm information and the sound alarm information can be "pay attention to pedestrians, the pilot has been locked", and the embodiment of the present application is not limited.
[0134] It can be seen that the optional embodiment can also transmit the alarm code to the display through the main controller to control the display to visually display the alarm information and output the alarm information through the buzzer, which can improve the flexibility and comprehensiveness of the internal alarm mode, effectively warn the driver of the safety risk, transmit the high level to the alarm and the warning light through the main controller, improve the control efficiency of the alarm module, improve the flexibility and comprehensiveness of the external alarm mode, effectively warn the external object of the safety risk, and help the external object to leave the working range of the engineering machinery in time.
[0135] In the optional embodiment, the specific way in which the main controller 102 controls the engineering machinery to perform the deceleration operation can include:
[0136] The main controller 102 controls the power of the engine of the engineering machinery to be reduced to the determined target power; or
[0137] The main controller 102 controls the proportional valve current corresponding to the engine of the engineering machinery to be reduced to the determined target current.
[0138] The current power of the engine is lower than the target power, and the current proportional valve current of the engine is lower than the target current.
[0139] It can be seen that the optional embodiment can also control the power of the engine of the engineering machinery to be reduced or the proportional valve current to be reduced through the main controller to control the engineering machinery to decelerate, which can improve the control flexibility and accuracy of the engineering machinery, thereby helping to improve the active safety control accuracy of the engineering machinery.

[0141] The specific way in which the main controller 102 controls the pilot switch module 105 to perform the passage disconnection operation to control the engineering machinery to stop operation can include:
[0142] The main controller 102 outputs a high-level signal to the pilot cut-off relay 1051 to control the pilot cut-off relay 1051 to be disconnected; in the case where the pilot cut-off relay 1051 is disconnected, the branch in which the pilot unlocking electromagnetic valve 1052 is located is disconnected, so that the branch in which the pilot cut-off valve switch 1053 is located is disconnected, thereby disconnecting the pilot oil circuit of the engineering machinery to control the engineering machinery to stop operation.
[0143] In detail, the main controller 102 outputs a high level signal to the pilot cut-off relay 1051, controls the pilot cut-off relay 1051 to be attracted, and controls the normally closed end point to be disconnected, so as to cut off the pilot unlocking electromagnetic valve 1052, that is, the pilot unlocking electromagnetic valve 1052 is not powered, so that the pilot cut-off valve switch 1053 cannot form a loop in the horizontal state or the vertical state, the pilot oil circuit is disconnected, and the whole machine cannot be controlled to continue operation, that is, the operation of the engineering machinery is stopped.
[0144] It can be seen that the optional embodiment can also output a high level to the pilot cut-off relay through the main controller to disconnect the pilot cut-off relay, so that the pilot unlocking electromagnetic valve is not powered, and the pilot cut-off valve switch cannot form a loop, resulting in the pilot oil circuit being disconnected to control the engineering machinery to stop operation, which can improve the control accuracy and reliability of the engineering machinery to stop operation in dangerous situations, thereby reducing the risk of accidents caused by the collision between the engineering machinery and external objects, and improving the operation safety of the engineering machinery.
[0145] In the optional embodiment, optionally, the main controller 102 is also used for detecting whether the hand and foot pilot pressure signals of the engineering machinery are received during the process of controlling the pilot switch module 105 to perform the path disconnecting operation to control the engineering machinery to stop operation.
[0146] The main controller 102 is also used for continuing to control the pilot switch module 105 to perform the path disconnecting operation to control the engineering machinery to stop operation when it is detected that the hand and foot pilot pressure signals of the engineering machinery are received.
[0147] Optionally, the hand and foot pilot pressure signals can include a hand pilot pressure signal and a foot pilot pressure signal, which are not limited by the embodiments of the present application; the hand pilot pressure signal can be a signal generated by the handle of the driver operating the engineering machinery, and the hand pilot pressure signal can be used to represent the completion of the turning, boom, and upper arm operations of the engineering machinery, which are not limited by the embodiments of the present application; the foot pilot pressure signal can be a signal generated by the foot pedal of the driver operating the engineering machinery, and the foot pilot pressure signal can be used to represent the completion of the forward and backward walking operations of the engineering machinery, which are not limited by the embodiments of the present application.
[0148] Optionally, the main controller 102 is also used for retriggering the panoramic monitoring module 101 to perform the operation of detecting whether the safety monitoring result meets the pre-set safety control condition after controlling the pilot switch module 105 to perform the path disconnecting operation to control the engineering machinery to stop operation when it is detected that the hand and foot pilot pressure signals of the engineering machinery are not received.
[0149] It can be seen that the optional embodiment can also continue the above-mentioned stop operation if the hand and foot pilot pressure signals are detected in the case of needing to control the engineering machinery to stop, so as to prevent the sudden change of the whole machine caused by the sudden change of the alarm signal from the red alarm to the yellow alarm or no alarm state during the red alarm whole vehicle stop action, and further improve the control accuracy and reliability of the control of the engineering machinery to stop in dangerous situations, thereby further improving the operation safety of the engineering machinery.

[0156] Please refer to Figure 7 , Figure 7 is a flowchart of an active safety control method based on panoramic monitoring disclosed by the embodiment of the present application. Among them, Figure 7 The active safety control method based on panoramic monitoring described can be applied to an active safety control system based on panoramic monitoring; wherein the system can be applied to engineering machinery, and can also be applied to the control system corresponding to the engineering machinery, which is not limited by the embodiment of the present application; wherein, optionally, the active safety control system based on panoramic monitoring can include a panoramic monitoring module, a main controller, a display, an alarm module and a pilot switch module, which are not limited by the embodiment of the present application; further, the method can be applied to the working scene of the engineering machinery, which is not limited by the embodiment of the present application. As Figure 7 shown, the active safety control method based on panoramic monitoring can include the following operations:
[0157] 201、When the main controller detects that the panoramic monitoring module meets the pre-set monitoring condition, the panoramic monitoring module monitors the active safety monitoring area corresponding to the engineering machinery to obtain a safety monitoring result.
[0158] In the embodiment of the present application, the active safety monitoring area includes a first area and a second area.
[0159] 202. The panoramic monitoring module detects whether the safety monitoring result meets the pre-set safety control condition.
[0160] 203. When it is detected that the safety monitoring result meets the safety control condition, the panoramic monitoring module sends alarm information corresponding to the safety monitoring result to the main controller.
[0161] 204. The main controller controls the target module corresponding to the alarm information to perform an alarm braking operation according to the received alarm information.
[0162] In the embodiment of the present application, the target module includes at least one of a display, an alarm module, and a pilot switch module.

The method can improve the timeliness and accuracy of the active safety control of the engineering machinery while improving the risk detection accuracy and efficiency of the working environment of the engineering machinery, thereby reducing the risk of safety accidents of the engineering machinery in the working process, and further improving the working safety of the engineering machinery.
[0164] In an optional embodiment, the method can further include the following operations:
[0165] The display detects whether there is a limit release instruction triggered by the driver corresponding to the engineering machinery, obtains an instruction detection result, and sends the instruction detection result to the main controller; the limit release instruction is used to release the safety limit function of the panoramic monitoring module;
[0166] When the instruction detection result indicates that there is no limit release instruction triggered by the driver corresponding to the engineering machinery, the main controller determines that the panoramic monitoring module meets the pre-set monitoring condition;
[0167] When the instruction detection result indicates that there is a limit release instruction triggered by the driver corresponding to the engineering machinery, the main controller determines whether the pilot switch module is in a locked state; when it is determined that the pilot switch module is in the locked state, the safety limit function of the panoramic monitoring module is released and it is determined that the panoramic monitoring module does not meet the pre-set monitoring condition.
[0168] It can be seen that the optional embodiment can detect whether the driver triggers the limit release instruction through the display. If the limit release instruction does not exist, it is determined that the panoramic monitoring module meets the preset monitoring condition, that is, the active safety control function can be started to monitor the active safety monitoring area. If the limit release instruction exists, it is further determined whether the pilot switch module is in the locked state. If yes, it is determined that the panoramic monitoring module does not meet the monitoring condition, that is, the active safety control function is not started. The judgment accuracy of whether the panoramic monitoring module meets the monitoring condition can be improved, thereby facilitating the intelligent determination of the starting condition of the active safety control function, improving the starting judgment accuracy and starting flexibility of the active safety control function of the engineering machinery, and further facilitating the improvement of the execution accuracy of the monitoring operation and the alarm operation of the panoramic monitoring module, and further facilitating the improvement of the operation safety of the engineering machinery.

[0173] The panoramic monitoring module detects whether the safety monitoring result meets the pre-set safety control condition, which can include the following operations:
[0174] The AVM host detects whether there is an external object in the active safety monitoring area corresponding to the engineering machinery according to the safety monitoring result;
[0175] The AVM host determines that the safety monitoring result meets the pre-set safety control condition when it is detected that there is an external object in the active safety monitoring area corresponding to the engineering machinery;
[0176] The AVM host determines that the safety monitoring result does not meet the pre-set safety control condition when it is detected that there is no external object in the active safety monitoring area corresponding to the engineering machinery;
[0177] Optionally, the panoramic monitoring module sends alarm information corresponding to the safety monitoring result to the main controller, which can include the following operations:
[0178] The AVM host determines the alarm information corresponding to the target region according to the target region where the external object is located, and sends the alarm information corresponding to the target region to the main controller; the target region is the first region or the second region.
[0179] It can be seen that the optional embodiment can also realize monitoring of the environment around the engineering machinery conveniently and comprehensively through the panoramic monitoring module composed of the camera unit and the AVM host, so as to provide comprehensive and real-time monitoring data to the driver on the display, which is conducive to improving the convenience and comprehensiveness of the driver observing the surrounding environment of the engineering machinery during the operation of the engineering machinery, and is conducive to improving the judgment accuracy of whether the safety monitoring result meets the safety control condition, thereby improving the active safety control accuracy of the engineering machinery; and the AVM host can also judge whether there is an external object in the active safety monitoring region, if it is detected that an external object enters the active safety monitoring region, it is determined that the safety monitoring result meets the safety control condition, that is, the active safety control function needs to be executed, otherwise, it is determined that the safety monitoring result does not meet the safety control condition, which can improve the detection accuracy of the external object entering the active safety monitoring region, thereby improving the judgment accuracy of whether the safety monitoring result meets the safety control condition, and further reducing the risk of collision between the engineering machinery and the external object during the operation process, thereby reducing the risk of safety accidents; and the AVM host can also send different alarm information to the main controller according to the region where the external object is located, which can improve the determination accuracy of the alarm information, thereby facilitating the issuance of different warnings and the execution of different alarm braking operations according to different distances between the external object and the engineering machinery, and facilitating flexible warning of the driver and the external object, and further improving the flexibility and accuracy of the active safety control of the engineering machinery, thereby improving the operation safety of the engineering machinery.
[0180] In another optional embodiment, the alarm information includes first alarm information corresponding to the first region or second alarm information corresponding to the second region;
[0181] The main controller controls the target module corresponding to the alarm information to perform the alarm braking operation according to the received alarm information, which can include the following operations:

[0185] It can be seen that the optional embodiment can specifically divide different alarm levels and other specific alarm information contents for the external object entering different monitoring areas, which is beneficial for the driver and the main controller to more accurately obtain the alarm information, thereby improving the alarm accuracy of the active safety control function, and further improving the active safety control accuracy of the engineering machine. In addition, the main controller can control the display and the alarm module to perform the internal alarm operation and the external alarm operation corresponding to the alarm information, which can improve the alarm flexibility and comprehensiveness of the active safety control function, thereby benefiting the driver and the external object to timely obtain the current safety risk situation, benefiting the external object to timely leave the working influence range of the engineering machine, and reducing the risk of safety accidents of the engineering machine in the working process. When the alarm information includes the first alarm information, the engineering machine is controlled to slow down, and when the alarm information includes the second alarm information, the engineering machine is controlled to stop, which can improve the flexibility of the braking operation when the external object enters different areas, improve the control accuracy of the working operation of the engineering machine, and further improve the accuracy of the active safety control of the engineering machine, and further reduce the risk of safety accidents of the engineering machine in the working process.

[0193] It can be seen that the optional embodiment can also output a high level to the pilot cut-off relay by the main controller to disconnect the pilot cut-off relay, so that the pilot unlocking electromagnetic valve is not powered, and the pilot cut-off valve switch cannot form a loop, resulting in the pilot oil circuit being disconnected to control the engineering machinery to stop operating, which can improve the control accuracy and reliability of controlling the engineering machinery to stop operating in dangerous situations, thereby reducing the risk of accidents caused by the collision between the engineering machinery and external objects and improving the operation safety of the engineering machinery.
[0194] In the optional embodiment, optionally, during the process that the main controller controls the pilot switch module to perform the path disconnection operation to control the engineering machinery to stop operating, the method can further include the following operations:
[0195] The main controller detects whether the hand and foot pilot pressure signals corresponding to the engineering machinery are received;
