The following are detailed descriptions.

[0089] Embodiment 1

[0090] See also Figure 1 , Figure 1 : is a schematic diagram of the structure of an active safety control system based on panoramic monitoring disclosed in an embodiment of the present invention. Figure 1 The described active safety control system based on panoramic monitoring can be applied to engineering machinery, and can also be applied to the control system corresponding to the engineering machinery, which is not limited in the embodiments of the present invention; further, the system can be applied to the operation scene of the engineering machinery, which is not limited in the embodiments of the present invention. Figure 1 As shown, the active safety control system based on panoramic monitoring may 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 to monitor the 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 the preset monitoring conditions; the active safety monitoring area includes a first area and a second area;

[0092] The panoramic monitoring module 101 is also used to detect whether the security monitoring result meets the preset security control condition; when it is detected that the security monitoring result meets the security control condition, an alarm message corresponding to the security monitoring result is sent to the main controller 102;

[0093] The main controller 102 is used to control the target module corresponding to the alarm information to perform the 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] Among them, optionally, the first area can be a deceleration area, and the second area can be a stop area, which is not limited in the embodiment of the present invention; further, the active safety monitoring area can be centered on the engineering machinery, and the area with the first length as the radius is the deceleration area, and the area with the second length as the radius is the stop area, and the first length is greater than the second length, which is not limited in the embodiment of the present invention; for example, please refer to Figure 3 , Figure 3 is a schematic diagram of the range of an active safety monitoring area disclosed in an embodiment of the present invention, wherein Figure 3 As shown, located Figure 3 The center is a construction machinery, and the first area is a deceleration area, and the second area is a stop area, which is not limited in the embodiment of the present invention.

[0095] Optionally, the panoramic monitoring module 101 may send the alarm information to the main controller 102 via a CAN (Controller Area Network) channel, which is not limited in the embodiment of the present invention.

[0096] It can be seen that the system described in the embodiment of the present invention can monitor the active safety monitoring area corresponding to the engineering machinery through the panoramic monitoring module to obtain a safety monitoring result when it is detected that the panoramic monitoring module meets the preset monitoring conditions. If it is detected that the safety monitoring result meets the preset safety control conditions, the main controller sends a corresponding alarm message, and then the main controller controls the target module corresponding to the alarm message to perform an alarm braking operation, so as to realize intelligent completion of active safety control when a safety risk is detected. There is no need for the driver to manually judge the safety situation of the driving environment or manually perform braking operations on the entire machine. While improving the accuracy and efficiency of risk detection in the operating environment of the engineering machinery, the timeliness and accuracy of the active safety control of the engineering machinery can be improved, thereby reducing the risk of safety accidents occurring during the operation of the engineering machinery, which is beneficial to improving the operating safety of the engineering machinery.

[0097] In an optional embodiment, the display 103 is used to detect whether there is a restriction release command triggered by the driver corresponding to the engineering 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 further configured to determine that the panoramic monitoring module 101 satisfies a preset monitoring condition when the command detection result indicates that there is no restriction release command triggered by the driver corresponding to the engineering machinery;

[0099] The main controller 102 is also used to determine whether the pilot switch module 105 is in a locked state when the command detection result is used to indicate that there is a restriction release command triggered by the driver corresponding to the engineering machinery; when it is determined that the pilot switch module 105 is in a locked state, the safety restriction function of the panoramic monitoring module 101 is released and it is determined that the panoramic monitoring module 101 does not meet the pre-set monitoring conditions.

[0100] Among them, optionally, the display 103 can be provided with a restriction release switch (such as a restriction release button), and the driver can trigger the restriction release instruction by triggering the restriction release switch; the display 103 can also be provided with a touch screen, and the driver can trigger the restriction release instruction by triggering the visual interface displayed on the touch screen, which is not limited to the embodiment of the present invention.

[0101] Among them, the safety restriction function of the panoramic monitoring module 101 can be used to start the active safety control process. Optionally, the panoramic monitoring module 101 can turn on the safety restriction function by default, so that the active safety control process can be executed in time, which is not limited in the embodiment of the present invention.

[0102] Among them, 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 embodiment of the present invention; further optionally, the pilot cut-off valve switch can be manually controlled by the driver, which is not limited in the embodiment of the present invention.

[0103] It can be seen that this optional embodiment can detect through the display whether there is a restriction release instruction triggered by the driver. If the restriction release instruction does not exist, it is determined that the panoramic monitoring module meets the preset monitoring conditions, that is, the active safety control function can be turned on to monitor the active safety monitoring area. If the restriction release instruction exists, it is necessary to further determine whether the pilot switch module is in a locked state. If so, it is determined that the panoramic monitoring module does not meet the monitoring conditions, that is, the active safety control function is not turned on. The accuracy of the judgment on whether the panoramic monitoring module meets the monitoring conditions can be improved, which is conducive to the realization of intelligent judgment on the conditions for starting the active safety control function, and the improvement of the start-up judgment accuracy and the start-up flexibility of the active safety control function of the construction machinery, which is conducive to improving the execution accuracy of the monitoring operation and alarm operation of the panoramic monitoring module, and is conducive to improving the operation safety of the construction machinery.

[0104] In this optional embodiment, optionally, as Figure 2 As shown, the panoramic monitoring module 101 may include a camera unit 1011 and an AVM (Around View Monitor, panoramic monitoring imaging system) host 1012, wherein:

[0105] The camera unit 1011 is used to monitor the active safety monitoring area corresponding to the engineering machinery, obtain safety monitoring results, and transmit the safety monitoring results to the AVM host 1012; the safety monitoring results include safety monitoring video data and / or safety monitoring image data;

[0106] The AVM host 1012 is used to transmit the security monitoring result to the display 103 so as to display the security monitoring result on the display 103.

[0107] Optionally, the camera unit 1011 may be a camera or a device with a camera function, which is not limited in the embodiment of the present invention.

[0108] It can be seen that this optional embodiment can also conveniently and comprehensively monitor the environment around the construction machinery through a panoramic monitoring module composed of a camera unit and an AVM host, so that comprehensive and real-time monitoring data can be provided to the driver on the display, which is beneficial to improving the convenience and comprehensiveness of the driver's observation of the surrounding environment of the construction machinery during operation, and is beneficial to improving the accuracy of judging whether the safety monitoring results meet the safety control conditions, thereby helping to improve the accuracy of active safety control of the construction machinery.

[0109] In this optional embodiment, the panoramic monitoring module 101 optionally detects whether the security monitoring result meets the preset security control condition in a specific manner, including:

[0110] The AVM host 1012 detects whether there is an external object in the active safety monitoring area corresponding to the construction machinery based on the safety monitoring results;

[0111] When the AVM host 1012 detects that there is an external object in the active safety monitoring area corresponding to the engineering machinery, it determines that the safety monitoring result meets the pre-set safety control condition;

[0112] When the AVM host 1012 detects that there is no external object in the active safety monitoring area corresponding to the construction machinery, it determines that the safety monitoring result does not meet the pre-set safety control conditions.

[0113] It can be seen that this optional embodiment can also determine whether there is an external object in the active safety monitoring area through the AVM host. If an external object is detected entering the active safety monitoring area, it is determined that the safety monitoring result meets the safety control conditions, 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 conditions. This can improve the detection accuracy of external objects entering the active safety monitoring area, thereby improving the accuracy of judging whether the safety monitoring results meet the safety control conditions, which in turn helps reduce the risk of safety accidents caused by collisions between construction machinery and external objects during operations.

[0114] Exemplarily, the external object may be a motor vehicle, a non-motor vehicle, a pedestrian, an animal, or other movable object, which is not limited in the embodiment of the present invention.

[0115] In this optional embodiment, the specific manner in which the panoramic monitoring module sends the alarm information corresponding to the security monitoring result to the main controller may include:

[0116] The AVM host determines the alarm information corresponding to the target area according to the target area where the external object is located, and sends the alarm information corresponding to the target area to the main controller; the target area is the first area or the second area.

[0117] It can be seen that this optional embodiment can also send different alarm information to the main controller through the AVM host according to the area where the external object is located, which can improve the accuracy of the alarm information, thereby facilitating the issuance of different warnings and the execution of different alarm braking operations for different distances between the external object and the construction machinery, and facilitating flexible warnings to the driver and the external object, and thereby improving the flexibility and accuracy of the active safety control of the construction machinery, which is beneficial to improving the operation safety of the construction machinery.

[0118] In an optional embodiment, the warning information may include first warning information corresponding to the first area or second warning information corresponding to the second area.

[0119] Among them, optionally, the first alarm information may include a combination of one or more of a first alarm level, a first alarm code, and a first alarm position, and the second alarm information may include a combination of one or more of a second alarm level, a second alarm code, and a second alarm position, which is not limited in the embodiment of the present invention.

[0120] The danger level corresponding to the first warning level is lower than the danger level corresponding to the second warning level.

[0121] Among them, exemplarily, the first alarm level can be a yellow alarm level, the first alarm code can be a yellow alarm code, the second alarm level can be a red alarm level, the second alarm code can be a red alarm code, and the first alarm position or the second alarm position can be used to indicate the location of the external object, which is not limited in the embodiments of the present invention.

[0122] It can be seen that this optional embodiment can also specifically divide different alarm levels and other specific alarm information contents for external objects entering different monitoring areas, which is beneficial for the driver and the main controller to obtain the alarm information more accurately, thereby facilitating the improvement of the alarm accuracy of the active safety control function, and further facilitating the improvement of the active safety control accuracy of the construction machinery.

[0123] In this optional embodiment, optionally, the specific manner in which the main controller 102 controls the target module corresponding to the warning information to perform the warning braking operation according to the received warning information may include:

[0124] 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; the internal alarm operation includes the warning visualization operation and the internal sound alarm operation for the alarm information; the external alarm operation includes the external sound and light alarm operation for the alarm information;

[0125] When the warning information includes the first warning information, the main controller 102 controls the engineering machine to perform a deceleration operation;

[0126] When the warning information includes the second warning information, the main controller 102 controls the pilot switch module 105 to perform a path disconnection operation to control the engineering machine to stop operating.

[0127] Among them, optionally, the warning visualization operation can be to display visual warning information (such as text warning information, graphic warning information) corresponding to the warning information on the display 103, and the internal sound warning operation can be to output the sound warning information corresponding to the warning information through the display 103 buzzer.

[0128] It can be seen that this optional embodiment can also control the display and the alarm module through the main controller to execute 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, so as to help the driver and the external object to be aware of the current safety risk situation in a timely manner, and help the external object to leave the corresponding operation influence range of the construction machinery in time, thereby reducing the risk of safety accidents occurring during the operation of the construction machinery; and when the alarm information includes the first alarm information, the construction machinery is controlled to decelerate, 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 taken when the external object enters different areas, and is conducive to improving the control accuracy of the operation operation of the construction machinery, and then is conducive to improving the accuracy of the active safety control of the construction machinery, and further reducing the risk of safety accidents occurring during the operation of the construction machinery.

[0129] In this optional embodiment, optionally, as Figure 2 As shown, the alarm module 103 may include an alarm 1041 and a 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 an internal alarm operation corresponding to the alarm information and control the alarm module 104 to perform an external alarm operation corresponding to the alarm information, which may 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 display 103 by buzzing;

[0132] The main controller 102 outputs high-level signals to the alarm 1041 and the warning light 1042 respectively, so as to control the alarm 1041 and the warning light 1042 to perform external sound and light alarm operations.

[0133] Among them, exemplarily, when the alarm information includes the first alarm information, the content represented by the visual alarm information and the sound alarm information can be: "Remind to pay attention to pedestrians, the whole 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: "Remind to pay attention to pedestrians, the pilot has been locked", which is not limited in the embodiment of the present invention.

[0134] It can be seen that this 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 by buzzing, which can improve the flexibility and comprehensiveness of the internal alarm method and effectively warn the driver of the safety risks; and, by transmitting a high level to the alarm and warning light through the main controller, it can improve the control efficiency of the alarm module, and improve the flexibility and comprehensiveness of the external alarm method, which can effectively warn external objects of the safety risks, which is conducive to the external objects leaving the corresponding operation influence range of the construction machinery in time.

[0135] In this optional embodiment, the specific manner in which the main controller 102 controls the engineering machinery to perform the deceleration operation may include:

[0136] The main controller 102 controls the engine power of the construction 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 construction machine to decrease 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 this optional embodiment can also control the power reduction of the engine of the engineering machinery or the reduction of the proportional valve current through the main controller to achieve the deceleration of the engineering machinery, 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.

[0140] In this optional embodiment, optionally, as Figure 2 As shown, the pilot switch module 105 includes a pilot cut-off relay 1051 , a pilot unlocking solenoid valve 1052 , and a pilot cut-off valve switch 1053 ;

[0141] The specific manner in which the main controller 102 controls the pilot switch module 105 to perform the path disconnection operation to control the engineering machinery to stop operation may 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; when the pilot cut-off relay 1051 is disconnected, the branch where the pilot unlocking solenoid valve 1052 is located is disconnected, so that the branch where 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 operating.

[0143] Specifically, the main controller 102 outputs a high-level signal to the pilot cut-off relay 1051, controls the pilot cut-off relay 1051 coil to be energized and the normally closed terminal to be disconnected, thereby cutting off the pilot unlocking solenoid valve 1052, that is, the pilot unlocking solenoid valve 1052 is not energized, so that the pilot cut-off valve switch 1053 cannot form a circuit regardless of whether it is in a horizontal state or a vertical state, disconnects the pilot oil circuit, and makes it impossible to control the entire construction machinery to continue operation, that is, controls the construction machinery to stop operating.

[0144] It can be seen that this 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, thereby making the pilot unlocking solenoid valve powerless, and further making it impossible for the pilot cut-off valve switch to form a circuit, resulting in the disconnection of the pilot oil circuit to control the construction machinery to stop operating. It can improve the control accuracy and reliability of controlling the construction machinery to stop operating in dangerous situations, thereby helping to reduce the risk of accidents caused by collisions between construction machinery and external objects and improving the operation safety of construction machinery.

[0145] In this optional embodiment, optionally, the main controller 102 is further used to detect whether the hand and foot pilot pressure signals corresponding to the engineering machinery are received during the process of controlling the pilot switch module 105 to perform the path disconnection operation to control the engineering machinery to stop the operation;

[0146] The main controller 102 is also used to continue to control the pilot switch module 105 to perform a path disconnection operation to control the engineering machinery to stop operating when it detects that the hand and foot pilot pressure signal corresponding to the engineering machinery is received.

[0147] Among them, optionally, the hand and foot lead pressure signals may include a hand lead pressure signal and a foot lead pressure signal, which is not limited in the embodiments of the present invention; wherein, the hand lead pressure signal may be a signal generated by the driver operating the handle of the engineering machinery, and exemplarily, the hand lead pressure signal may be used to indicate that the engineering machinery completes operations such as rotation, bucket arm, and upper arm movement, which is not limited in the embodiments of the present invention; the foot lead pressure signal may be a signal generated by the driver operating the foot pedal, and exemplarily, the foot lead pressure signal may be used to indicate that the engineering machinery completes the forward, backward, left, and right walking movements of the whole machine, which is not limited in the embodiments of the present invention.

[0148] Optionally, the main controller 102 is also used to re-trigger the panoramic monitoring module 101 to execute an operation to detect whether the safety monitoring results meet pre-set safety control conditions after controlling the pilot switch module 105 to perform a path disconnection operation to control the engineering machinery to stop operating when it detects that the hand and foot pilot pressure signals corresponding to the engineering machinery are not received.

[0149] It can be seen that this optional embodiment can also continue the above-mentioned stop operation if a hand and foot pilot pressure signal is detected when it is necessary to control the construction machinery to stop, so as to prevent the alarm signal from suddenly entering a yellow alarm or no alarm state during the red alarm vehicle stopping process, thereby causing sudden action of the whole machine. This can further improve the control accuracy and reliability of controlling the stop operation of construction machinery in dangerous situations, which is conducive to further improving the operation safety of construction machinery.

[0150] In the embodiment of the present invention, for example, the architecture of the active safety control system based on panoramic monitoring can be referred to Figure 4 , Figure 4 is a schematic diagram of the structure of another active safety control system based on panoramic monitoring disclosed in an embodiment of the present invention.

[0151] In the embodiment of the present invention, for example, the connection relationship between the components in the active safety control system based on panoramic monitoring can be referred to in Figure 5 , Figure 5 is a schematic diagram of the structure of another active safety control system based on panoramic monitoring disclosed in an embodiment of the present invention. Figure 5 As shown, the active safety control system based on panoramic monitoring includes a main controller, a display, an AVM host, a pilot cut-off relay, a pilot unlocking solenoid valve, a pilot cut-off valve switch, a warning light and an alarm, among which:

[0152] The first end of the main controller is electrically connected to the first end of the display; the second end of the main controller is electrically connected to the first end of the AVM host, and the third end of the main controller is used to receive the hand and foot electrical pilot signal (that is, the hand and foot pilot pressure signal); the fourth end of the main controller is used to receive the engine speed signal, wherein the engine speed signal can be used to determine whether the engine is started; the fourth end of the main controller is electrically connected to the first end of the warning light, the fifth end of the main controller is electrically connected to the first end of the alarm, and the second end of the warning light and the second end of the alarm are respectively used for grounding; the sixth end of the main controller is electrically connected to the pilot cut-off relay The first end is electrically connected, the second end of the pilot cut-off relay is used for grounding, the third end of the pilot cut-off relay is used for electrically connecting to a power supply (such as: DC24V), and the fourth end of the pilot cut-off relay is electrically connected to the first end of the pilot unlocking solenoid valve; the seventh end of the main controller (the normally open end in the pilot cut-off signal end) is electrically connected to the second end of the pilot unlocking solenoid valve and the first end of the pilot cut-off valve switch respectively, the eighth end of the main controller (the normally closed end in the pilot cut-off signal end) is electrically connected to the second end of the pilot cut-off valve switch, and the third end of the pilot cut-off valve switch and the fourth end of the pilot cut-off valve switch are both used for grounding.

[0153] In the embodiment of the present invention, for example, the logic control process of the active safety control system based on panoramic monitoring can be referred to Figure 6 , Figure 6 : is a schematic diagram of a logic control flow of an active safety control system based on panoramic monitoring disclosed in an embodiment of the present invention. The flow may include the following operations:

[0154] After the active safety control system is powered on, the AVM host starts to monitor pedestrians and uploads alarm information to the main controller when it detects that pedestrians enter the range of the active safety monitoring area; the main controller detects whether the display is triggered by the restriction release instruction of the switch of the safety restriction function of the AVM host; if there is a restriction release instruction, the active safety control system does not execute the active safety control function of the whole machine; if the restriction release instruction is not triggered, it further determines whether the engine is started and whether the pilot cut-off valve switch is in the unlocked state. If the engine is not started or the pilot cut-off valve switch is in the locked state, the active safety control system does not execute the active safety control function of the whole machine; if the engine is started and the pilot cut-off valve switch is in the unlocked state, it further determines whether it is within the range of the active safety monitoring area. A yellow alarm or a red alarm appears; if there is no alarm, the active safety control function of the whole machine will not be executed; if it is a yellow alarm, the whole machine will be controlled to perform a deceleration operation, and the display will be controlled to remind the driver to pay attention to pedestrians and the whole machine has decelerated, and the external sound and light alarm will be controlled; if it is a red alarm, the whole machine will be controlled to stop by controlling the pilot cut-off relay, and the display will be controlled to remind the driver to pay attention to pedestrians and the pilot has been locked, and the external sound and light alarm will be controlled; in the case of a red alarm, if a hand or foot pilot pressure signal is detected, the above-mentioned operation of controlling the whole machine to stop will continue to prevent the alarm signal from suddenly entering a yellow alarm or no alarm state during the red alarm vehicle stopping process, causing a sudden change in the whole machine; if no hand or foot pilot pressure signal is detected, the next round of logical judgment process can be re-executed.

[0155] Embodiment 2

[0156] See also Figure 7 , Figure 7 : is a flow chart of an active safety control method based on panoramic monitoring disclosed in an embodiment of the present invention. Figure 7 The described active safety control method based on panoramic monitoring 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 embodiments of the present invention; 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 is not limited by the embodiments of the present invention; further, the method can be applied to the operation scene of engineering machinery, which is not limited by the embodiments of the present invention. Figure 7 As shown, the active safety control method based on panoramic monitoring may include the following operations:

[0157] 201. When the main controller detects that the panoramic monitoring module meets the preset monitoring conditions, the panoramic monitoring module monitors the active safety monitoring area corresponding to the construction machinery to obtain the safety monitoring result.

[0158] In the embodiment of the present invention, the active safety monitoring area includes a first area and a second area.

[0159] 202. The panoramic monitoring module detects whether the security monitoring results meet the pre-set security control conditions.

[0160] 203. When it is detected that the security monitoring result meets the security control condition, the panoramic monitoring module sends an alarm message corresponding to the security monitoring result to the main controller.

[0161] 204. The main controller controls the target module corresponding to the alarm information to perform the alarm braking operation according to the received alarm information.

[0162] In the embodiment of the present invention, the target module includes at least one of a display, an alarm module and a pilot switch module.

[0163] It can be seen that the method described in the embodiment of the present invention can monitor the active safety monitoring area corresponding to the engineering machinery through the panoramic monitoring module to obtain a safety monitoring result when it is detected that the panoramic monitoring module meets the preset monitoring conditions. If it is detected that the safety monitoring result meets the preset safety control conditions, the main controller sends the corresponding alarm information, and then the main controller controls the target module corresponding to the alarm information to perform the alarm braking operation, so as to realize intelligent completion of active safety control when a safety risk is detected, without the need for the driver to manually judge the safety situation of the driving environment or manually perform the braking operation of the entire machine. It can improve the accuracy and efficiency of risk detection in the operating environment of the engineering machinery, and at the same time improve the timeliness and accuracy of the active safety control of the engineering machinery, thereby reducing the risk of safety accidents occurring during the operation of the engineering machinery, which is beneficial to improving the operating safety of the engineering machinery.

[0164] In an optional embodiment, the method may further include the following operations:

[0165] The display detects whether there is a restriction release command triggered by the driver corresponding to the engineering machinery, obtains the command detection result, and sends the command detection result to the main controller; the restriction release command is used to release the safety restriction function of the panoramic monitoring module;

[0166] When the command detection result indicates that there is no restriction release command triggered by the driver corresponding to the construction machinery, the main controller determines that the panoramic monitoring module meets the preset monitoring condition;

[0167] When the command detection result is used to indicate that there is a restriction release command triggered by the driver corresponding to the construction 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 a locked state, the safety restriction function of the panoramic monitoring module is released and it is determined that the panoramic monitoring module does not meet the pre-set monitoring conditions.

[0168] It can be seen that this optional embodiment can detect through the display whether there is a restriction release instruction triggered by the driver. If the restriction release instruction does not exist, it is determined that the panoramic monitoring module meets the preset monitoring conditions, that is, the active safety control function can be turned on to monitor the active safety monitoring area. If the restriction release instruction exists, it is necessary to further determine whether the pilot switch module is in a locked state. If so, it is determined that the panoramic monitoring module does not meet the monitoring conditions, that is, the active safety control function is not turned on. The accuracy of the judgment on whether the panoramic monitoring module meets the monitoring conditions can be improved, which is conducive to the realization of intelligent judgment on the conditions for starting the active safety control function, and the improvement of the start-up judgment accuracy and the start-up flexibility of the active safety control function of the construction machinery, which is conducive to improving the execution accuracy of the monitoring operation and alarm operation of the panoramic monitoring module, and is conducive to improving the operation safety of the construction machinery.

[0169] In this optional embodiment, optionally, the panoramic monitoring module includes a camera unit and an AVM host;

[0170] Among them, the panoramic monitoring module monitors the active safety monitoring area corresponding to the construction machinery and obtains the safety monitoring results, which may include the following operations:

[0171] The camera unit monitors the active safety monitoring area corresponding to the engineering machinery, obtains safety monitoring results, and transmits the safety monitoring results to the AVM host; the safety monitoring results include safety monitoring video data and / or safety monitoring image data;

[0172] The AVM host transmits the security monitoring result to the display so as to display the security monitoring result on the display;

[0173] The panoramic monitoring module detects whether the security monitoring results meet the pre-set security control conditions, which may include the following operations:

[0174] Based on the safety monitoring results, the AVM host detects whether there are external objects in the active safety monitoring area corresponding to the construction machinery;

[0175] When the AVM host detects that there is an external object in the active safety monitoring area corresponding to the construction machinery, it determines that the safety monitoring result meets the pre-set safety control conditions;

[0176] When the AVM host detects that there is no external object in the active safety monitoring area corresponding to the engineering machinery, it determines that the safety monitoring result does not meet the pre-set safety control conditions;

[0177] Optionally, the panoramic monitoring module sends alarm information corresponding to the security monitoring result to the main controller, which may include the following operations:

[0178] The AVM host determines the alarm information corresponding to the target area according to the target area where the external object is located, and sends the alarm information corresponding to the target area to the main controller; the target area is the first area or the second area.

[0179] It can be seen that this optional embodiment can also conveniently and comprehensively monitor the environment around the construction machinery through a panoramic monitoring module composed of a camera unit and an AVM host, so as to provide the driver with comprehensive and real-time monitoring data on the display, which is conducive to improving the convenience and comprehensiveness of the driver's observation of the surrounding environment of the construction machinery when the whole machine is operating, and is conducive to improving the accuracy of judging whether the safety monitoring results meet the safety control conditions, thereby helping to improve the accuracy of active safety control of the construction machinery; and, it is also possible to judge whether there is an external object in the active safety monitoring area through the AVM host. If an external object is detected to enter the active safety monitoring area, it is determined that the safety monitoring results meet the safety control conditions, that is, the active safety control function needs to be executed, otherwise it will be determined. Then, determining that the safety monitoring results do not meet the safety control conditions can improve the detection accuracy of external objects entering the active safety monitoring area, thereby improving the accuracy of judging whether the safety monitoring results meet the safety control conditions, which is beneficial to reducing the risk of safety accidents caused by collisions between construction machinery and external objects during operation; and, the AVM host can also send different alarm information to the main controller according to the area where the external object is located, which can improve the accuracy of determining the alarm information, thereby facilitating the issuance of different warnings and the execution of different alarm braking operations for different distances between the external object and the construction machinery, which is beneficial to flexibly alerting the driver and the external object, and thereby improving the flexibility and accuracy of the active safety control of the construction machinery, which is beneficial to improving the operation safety of the construction machinery.

[0180] In yet another optional embodiment, the warning information includes first warning information corresponding to the first area or second warning information corresponding to the second area;

[0181] Among them, 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 may include the following operations:

[0182] The main controller outputs the received alarm information to the display and the alarm module respectively, so as to control the display to execute the internal alarm operation corresponding to the alarm information and control the alarm module to execute the external alarm operation corresponding to the alarm information; the internal alarm operation includes the warning visualization operation and the internal sound alarm operation for the alarm information; the external alarm operation includes the external sound and light alarm operation for the alarm information;

[0183] When the warning information includes the first warning information, the main controller controls the engineering machinery to perform a deceleration operation;

[0184] When the warning information includes the second warning information, the main controller controls the pilot switch module to perform a path disconnection operation to control the engineering machinery to stop operating.

[0185] It can be seen that this optional embodiment can specifically divide different alarm levels and other specific alarm information contents for external objects entering different monitoring areas, which is beneficial for the driver and the main controller to obtain the alarm information more accurately, thereby improving the alarm accuracy of the active safety control function, and further improving the active safety control accuracy of the engineering machinery; and, it can also control the display and the alarm module through the main controller to execute 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 facilitating the driver and the external object to be able to know the current safety risk situation in time, and facilitating the external object to leave the corresponding operation influence range of the engineering machinery in time, reducing the risk of safety accidents occurring during the operation of the engineering machinery; and when the alarm information includes the first alarm information, the engineering machinery is controlled to decelerate, and when the alarm information includes the second alarm information, the engineering machinery is controlled to stop, which can improve the flexibility of the braking operation taken when the external object enters different areas, which is beneficial to improve the control accuracy of the operation operation of the engineering machinery, and further improve the accuracy of the active safety control of the engineering machinery, and further reduce the risk of safety accidents occurring during the operation of the engineering machinery.

[0186] In this optional embodiment, optionally, the main controller controls the engineering machinery to perform a deceleration operation, which may include the following operations:

[0187] The main controller controls the engine of the construction machinery to reduce the power to the determined target power; or,

[0188] The main controller controls the proportional valve current corresponding to the engine of the engineering machinery to be reduced to the determined target current.

[0189] It can be seen that this optional embodiment can also control the power reduction of the engine of the engineering machinery or the reduction of the proportional valve current through the main controller to achieve the deceleration of the engineering machinery, 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.

[0190] In this optional embodiment, optionally, the pilot switch module includes a pilot cut-off relay, a pilot unlocking solenoid valve, and a pilot cut-off valve switch;

[0191] The main controller controls the pilot switch module to perform a path disconnection operation to control the engineering machinery to stop operation, which may include the following operations:

[0192] The main controller outputs a high-level signal to the pilot cut-off relay to control the pilot cut-off relay to disconnect; when the pilot cut-off relay is disconnected, the branch where the pilot unlocking solenoid valve is located is disconnected, so that the branch where the pilot cut-off valve switch is located is disconnected, thereby disconnecting the pilot oil circuit of the construction machinery to control the construction machinery to stop operating.

[0193] It can be seen that this 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, thereby making the pilot unlocking solenoid valve powerless, and further making it impossible for the pilot cut-off valve switch to form a circuit, resulting in the disconnection of the pilot oil circuit to control the construction machinery to stop operating. It can improve the control accuracy and reliability of controlling the construction machinery to stop operating in dangerous situations, thereby helping to reduce the risk of accidents caused by collisions between construction machinery and external objects and improving the operation safety of construction machinery.

[0194] In this optional embodiment, optionally, in the process where the main controller controls the pilot switch module to perform the path disconnection operation to control the engineering machinery to stop operation, the method may further include the following operations:

[0195] The main controller detects whether it has received the hand and foot pilot pressure signals corresponding to the engineering machinery;

[0196] When it is detected that the hand and foot pilot pressure signals corresponding to the engineering machinery are received, the main controller continues to control the pilot switch module to perform the path disconnection operation to control the engineering machinery to stop operating;

[0197] When it is detected that the hand and foot pilot pressure signals corresponding to the engineering machinery are not received, the panoramic monitoring module is triggered to execute an operation of detecting whether the safety monitoring results meet the pre-set safety control conditions.

[0198] It can be seen that this optional embodiment can also continue the above-mentioned stop operation if a hand and foot pilot pressure signal is detected when it is necessary to control the construction machinery to stop, so as to prevent the alarm signal from suddenly entering a yellow alarm or no alarm state during the red alarm vehicle stopping process, thereby causing sudden action of the whole machine. This can further improve the control accuracy and reliability of controlling the stop operation of construction machinery in dangerous situations, which is conducive to further improving the operation safety of construction machinery.
