TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent construction, in particular to a high-voltage line under engineering machinery construction vehicle end control device, a control system and a control method. BACKGROUND

[0002] In the process of modernization, cranes and other large engineering machinery are widely used. When these engineering machinery work under high-voltage lines, the situation of accidentally touching live lines often occurs, causing line short circuit tripping, conductor damage, large area power outage, even vehicle damage and death, and great influence.

[0003] At present, it mainly depends on traditional periodic manual inspection. This method has many problems such as low efficiency, time-consuming and laborious, human negligence, and lax supervision, and cannot achieve the effect of timely prevention and on-site stop.

[0004] Patent CN201210510272.7 discloses a safety distance detection and early warning device and method for electric power construction equipment, which comprises a sensor part and a main control equipment part. The sensor part comprises a plurality of wireless ranging sensors, and the main control equipment part comprises a central processing module, a wireless data receiving module and an alarm module. The wireless data receiving module is connected with the wireless ranging sensor, and the central processing module is connected with the wireless data receiving module and the sound and light alarm module.

[0005] All devices of the scheme are installed on the electric power construction equipment (crane). The wireless ranging sensor is installed at the front of the boom, and the video camera is installed at the bottom of the boom. The wireless ranging sensor detects whether there is an obstacle in the preset safety range. If there is an obstacle, the central processing module is informed.

DETAILED DESCRIPTION

[0044] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0045] In the description of the present application, it should be understood that when one element is considered to be "connected" to another element, it can be directly connected to the other element or a middle element can exist at the same time.

[0046] The existing risk control scheme for construction under high-voltage lines only detects and alarms the spatial distance, and the user does not know the risk size of the current alarm prompt; in addition, the existing scheme does not automatically limit the action of the engineering machinery when the engineering machinery approaches or is less than the safe distance from the high-voltage transmission line, and when the risk occurs, if the operator does not realize and continues to operate the engineering machinery to move in the dangerous direction, it will also cause a safety accident to occur, and the degree of intelligence is not high. Based on this, the present application proposes a vehicle-mounted end control device for engineering machinery construction under high-voltage lines, a control system and a control method, which realizes risk grading prompt, adaptively intervenes in the action of the engineering machinery according to the risk level, and improves the safety, practicality and degree of intelligence. The technical solutions of the present application will be described in detail below in combination with specific embodiments.

[0047] Embodiment 1

[0048] As Figure 1As shown, the embodiment provides a high-voltage line under construction vehicle-mounted end control device of engineering machinery, including control module 1013, and wireless module 1019, risk indication module 1011, interface module 1015, power supply module 1017 connected with the control module 1013;

[0049] The wireless module 1019 is used for data interaction between the control module 1013 and the outside, and the data includes the risk level determined according to the distance between the construction engineering machinery and the high-voltage line;

[0050] The control module 1013 is used for sending the risk instruction of the corresponding level to the risk indication module 1011 according to the risk level transmitted by the wireless module 1019, and sending the engineering machinery action control instruction of the corresponding level to the engineering machinery through the interface module 1015;

[0051] The risk indication module 1011 is used for risk indication of the corresponding level according to the received risk instruction;

[0052] The interface module 1015 is used for data interaction with the engineering machinery;The interface module 1015 has the hardware interface of CAN communication and has the functions of CAN data sending and receiving, the interface module 1015 sends the data to be sent by the control module 1013, and provides the received CAN data to the control module 1013;

[0053] The power supply module 1017 is used for power supply processing and distribution of each module in the vehicle-mounted end control device, so that the power supply of different modules of the vehicle-mounted end control device can meet the working requirements in the working process;The power supply module 1017 can select a storage battery for power supply, or can select a power supply from the engineering machinery through the interface module 1015, and supply power to each module through the power supply module 1017.

[0054] The vehicle-mounted end control device 101 can be placed in the cab or operating room of the engineering machinery 102, and connected or disconnected with the CAN interface of the engineering machinery 102 through the interface module 1015 in a plug-and-play manner, which is simple and convenient to use. Since the vehicle-mounted end control device can be directly placed in the operating room, the complex modification and installation problems of the mechanical structure and power supply line of the engineering machinery are avoided. The engineering quantity is simplified, the product cost is reduced, and the practicability of the product is improved. According to the risk level determined according to the distance between the construction engineering machinery and the high-voltage line, adaptive alarm and control are performed, specifically, different levels of risk indication are performed for different risk levels, and different levels of action control intervention are performed on the engineering machinery for different risk levels, thereby effectively reducing the possibility of the engineering machinery colliding with the high-voltage line. Since it can automatically intervene to limit the action of the engineering machinery, when the risk occurs and the operator does not realize it and continues to operate the engineering machinery to move in the dangerous direction, the vehicle-mounted end control device will also automatically limit or even stop the action of the engineering machinery to avoid safety accidents, which has higher safety and practicability than simply prompting the operator of the danger.

[0055] In specific implementation, the number of risk levels is set according to actual needs, and three risk levels are set in the embodiment, and the risk levels include a first risk level, a second risk level and a third risk level determined in turn from large to small according to the distance. When the first risk level, the risk instruction sent by the control module 1013 is the first level risk instruction, the risk indication module 1011 indicates according to the indication mode defined by the first level risk instruction, the engineering machinery action control instruction sent by the control module 1013 is the first action control instruction, and the engineering machinery operates according to the action defined by the first action control instruction. When the second risk level, the risk instruction sent by the control module 1013 is the second level risk instruction, the risk indication module 1011 indicates according to the indication mode defined by the second level risk instruction, the engineering machinery action control instruction sent by the control module 1013 is the second action control instruction, and the engineering machinery operates according to the action defined by the second action control instruction. When the third risk level, the risk instruction sent by the control module 1013 is the third level risk instruction, the risk indication module 1011 indicates according to the indication mode defined by the third level risk instruction, the engineering machinery action control instruction sent by the control module 1013 is the third action control instruction, and the engineering machinery operates according to the action defined by the third action control instruction.

[0056] In this embodiment, the indication manners defined by the first-level risk instruction, the second-level risk instruction and the third-level risk instruction are respectively light flashing at three different frequencies; the actions defined by the first action control instruction, the second action control instruction and the third action control instruction are respectively no intervention, reducing engine speed and engine shutdown. It should be noted that the indication manners defined by the risk instructions can also be selected as sound and light alarm manners or other alarm manners, and the indication manners of different levels of risk instructions should be different. In other embodiments, the risk levels can also be divided into 4 levels, 5 levels, etc., and the actions defined by the action control instructions corresponding to the intermediate risk levels can be different degrees of engine speed, and the higher the risk level, the lower the limited engine speed.

[0057] Embodiment 2

[0058] As shown in Figure 1 , the embodiment provides a high-voltage off-line engineering machinery construction vehicle end control device, which is different from the embodiment 1 in that it further comprises a bridge module 105 connected with the interface module 1015, and the bridge module 105 is used for adapting the interface module 1015 of the vehicle end control device 101 to the interfaces of different types of engineering machinery 102.

[0059] Since the engines of different types of engineering machinery 102 are all equipped with CAN interfaces 1021, the CAN interfaces 1021 are connected with the vehicle control modules 1022 of the engineering machinery, and after adding the bridge module 105, it is not necessary to design and process complex mounting structures on the engineering machinery 102 or to modify the engineering machinery 102, and the vehicle end control device 101 is connected with the engines of different types and models of engineering machinery in a direct plug-in manner through the bridge module 105 to work, thereby improving the applicability.

[0060] Specifically, as shown in Figure 3 , it is a structural schematic diagram of the bridge module 105, one side of which is a CAN plug connector 1054 matched with the interface module 1015, and the other side connected with the CAN plug connector 1054 is a plurality of CAN plug connectors (a first plug connector 1051, a second CAN plug connector 1052, …, an n-th CAN plug connector 1053), wherein the plurality of CAN plug connectors (the first plug connector 1051, the second CAN plug connector 1052, …, the n-th CAN plug connector 1053) can be matched with the CAN interfaces 1021 of the engineering machinery 102 of different interface forms and different interface pin signal definitions respectively.

[0061] Preferably, the bridging module 105 has CAN high and CAN low pins for communication between the vehicle-mounted control device 101 and the engine of the construction machinery 102. The bridging module 105 also has positive and negative power pins for the vehicle-mounted control device 101 to obtain external power from the construction machinery 102.

[0062] Example 3

[0063] like Figure 1 As shown, this embodiment provides a vehicle-mounted control device for construction machinery under high voltage lines. The difference between this device and embodiment 1 or embodiment 2 is that it also includes a setting module 1014 and a display module 1012 connected to the control module 1013.

[0064] The setting module 1014 is used to set and modify the address information of the construction machinery;

[0065] The display module 1012 is used to display the address information of the construction machinery and the engine speed.

[0066] In practical implementation, after the vehicle-mounted control device 101 is connected to the construction machinery 102, the vehicle-mounted control device 101 receives power, and the operator operates the setting module 1014 to set the address information of the construction machinery (e.g., set to "6956"). After the setting is completed, the control module 1013 sends the construction machinery address information "6956" to the external central control device 103 through the wireless module 1019, realizing the matching between the vehicle-mounted control device 101 and the central control device 103.

[0067] Example 4

[0068] like Figure 1 As shown, this embodiment provides a vehicle-mounted control device for construction machinery under high-voltage lines. The difference between this device and any of embodiments 1 to 3 is that it further includes a power-off retention module 1018 connected to the power supply module 1017. During operation, the power supply module 1017 automatically monitors the power supply status in real time. When the power supply is normal, the power supply module 1017 supplies the received external power to the vehicle-mounted control device and also supplies power to the power-off retention module 1018 for energy storage. When a power supply abnormality is detected, the power-off retention module 1018 automatically supplies power to the power supply module 1017, thereby ensuring that the device can continue to receive normal power for a period of time when the external power supply is abnormal. During this period, the vehicle-mounted control device 101 automatically sends an external power supply abnormality message to the central control device 103 for abnormality handling.

[0069] Example 5

[0070] like Figure 1As shown, this embodiment provides a vehicle-mounted control device for construction machinery under high-voltage lines. The difference between this device and any of embodiments 1 to 4 is that it further includes a voice broadcast module 1016 connected to the control module 1013. This voice broadcast module 1016 plays different voice prompts based on different voice commands issued by the control module 1013. The voice prompts are set according to risk levels. Taking three risk levels as an example, at the first risk level, the control module 1013 issues a first-level voice command to the voice broadcast module 1016 to broadcast the first-risk-level voice prompt (e.g., "Operation is risky, please operate with caution"); at the second risk level, the control module 1013 issues a second-level voice command to the voice broadcast module 1016 to broadcast the second-risk-level voice prompt (e.g., "Operation is at risk of collision, please slow down"); at the third risk level, the control module 1013 issues a third-level voice command to the voice broadcast module 1016 to broadcast the third-risk-level voice prompt (e.g., "A collision is imminent, please stop operation immediately").

[0071] Of course, in other embodiments, a corresponding number of different voice entries can be set to provide reminders based on the actual number of risk levels. The specific content of the voice entries can be set according to actual needs, so as to distinguish the risk levels and provide risk warnings.

[0072] Example 6

[0073] like Figure 1 As shown, this embodiment provides a vehicle-mounted control device for construction machinery under high voltage lines. The difference between this device and any one of embodiments 1 to 5 is that it also includes an antenna 104 connected to the wireless module 1019, which is used to increase the power gain of the wireless module 1019 and thus increase the transmission distance of the data signal.

[0074] Example 7

[0075] like Figure 2 As shown, this embodiment provides a construction machinery control system for high-voltage power lines, including a central control device 103 and a vehicle-mounted control device 101 for construction machinery under high-voltage power lines as described in any one of embodiments 1 to 6.

[0076] The central control device 103 is used to determine the risk level based on the distance between the construction machinery and the high-voltage line, and then send the risk level to the vehicle-mounted control device 101.

[0077] In implementation, the central control device 103 is placed near the high-voltage line tower to determine the risk level according to the detected distance between the construction engineering machinery and the high-voltage line, and send it to the vehicle-mounted control device 101. At the same time, the vehicle-mounted control device 101 and the CAN interface 1021 of the engineering machinery 102 are connected in a plug-in manner, so that the vehicle-mounted control device 101 can be directly placed in the engineering machinery 102 operating room. In this way, it is no longer necessary to make complex modifications and installation work on the mechanical structure and power supply line of the engineering machinery 102, reducing the workload, cost and complexity, and improving the use convenience and practicality.

[0078] Based on the vehicle-mounted control device for engineering machinery construction under high-voltage line described in the above embodiment, the embodiment of the present application also provides a control method for engineering machinery construction under high-voltage line. In this embodiment, a crane is taken as an example to divide three risk levels, as shown in the figure, the control method comprises: Figure 4

[0079] (1) Connect the CAN plug-in connector on one side of the bridge module 105 with the vehicle-mounted control device 101, and connect the matching CAN plug-in connector on the other side with the CAN interface of the engineering machinery 102.

[0081] (3) The operator operates the vehicle-mounted control device 101 to set the engineering machinery address information, and the setting process and result are displayed in real time on the display module 1012.

[0082] (4) The control module 1013 of the vehicle-mounted control device 101 sends the address information to the wireless module 1019, and the wireless module 1019 sends the address information to the remote central control device 103.

[0083] (5) During the construction process of the engineering machinery 102, if the wireless module 1019 of the vehicle-mounted control device 101 receives the message BWT=tMSG[A] sent by the remote central control device 103, the wireless module 1019 sends the message to the control module 1013 of the vehicle-mounted control device 101. The control module 1013 controls the voice broadcast module 1016 to play the voice according to the content defined by vST[A] to inform the user of the current risk level, and controls the risk indication module 1011 to prompt the user according to the mode defined by bST[A]. At the same time, the control module 1013 sends the content instruction defined by eCMD[A] to the engineering machinery 102 through the interface module 1015 to change the operation mode of the engineering machinery.

[0084] ​(6) If the wireless module 1019 of the on-board control device 101 receives the message BWT = tMSG_p[A] sent by the remote central control device 103, the wireless module 1019 sends the message to the control module 1013 of the on-board control device 101. The control module 1013 controls the voice broadcast module 1016 to stop playing the voice defined by vST[A], and controls the risk indication module 1011 to stop prompting in the manner defined by bST[A]. At the same time, the control module 1013 stops sending the message defined by eCMD[A] to the construction machinery 102 through the interface module 1015.

[0085] (7) If the wireless module 1019 of the on-board control device 101 receives the message BWT = tMSG[B] sent by the remote central control device 103, the wireless module 1019 sends the message to the control module 1013 of the on-board control device 101. The control module 1013 controls the voice broadcast module 1016 to play the voice defined by vST[B] to inform the user of the current risk level, and controls the risk indication module 1011 to prompt the user in the manner defined by bST[B]. At the same time, the control module 1013 sends the content defined by eCMD[B] to the construction machinery 102 to change the operation mode of the construction machinery through the interface module 1015.

[0086] (8) If the wireless module 1019 of the on-board control device 101 receives the message BWT = tMSG_p[B] sent by the remote central control device 103, the wireless module 1019 sends the message to the control module 1013 of the on-board control device 101. The control module 1013 controls the voice broadcast module 1016 to stop playing the voice defined by vST[B], and controls the risk indication module 1011 to stop prompting in the manner defined by bST[B]. At the same time, the control module 1013 stops sending the message defined by eCMD[B] to the construction machinery 102 through the interface module 1015.

[0087] (9) If the wireless module 1019 of the on-board control device 101 receives the message BWT = tMSG[C] sent by the remote central control device 103, the wireless module 1019 sends the message to the control module 1013 of the on-board control device 101. The control module 1013 controls the voice broadcast module 1016 to play the voice defined by vST[C] to inform the user of the current risk level, and controls the risk indication module 1011 to prompt the user in the manner defined by bST[C]. At the same time, the control module 1013 sends the content defined by eCMD[C] to the construction machinery 102 to change the operation mode of the construction machinery through the interface module 1015.

[0088] (10) If the wireless module 1019 of the vehicle-mounted control device 101 receives the message BWT=tMSG_p[C] sent by the remote central control device 103, the wireless module 1019 sends the message to the control module 1013 of the vehicle-mounted control device 101. The control module 1013 controls the voice broadcast module 1016 to stop playing the voice defined by vST[C], and controls the risk indication module 1011 to stop prompting in the manner defined by bST[C]. At the same time, the control module 1013 stops sending the message defined by eCMD[C] to the engineering machinery 102 through the interface module 1015.

[0089] Wherein tMSG[A], tMSG[B], tMSG[C], tMSG_p[A], tMSG_p[B] and tMSG_p[C] represent different message contents respectively; vST[A], vST[B] and vST[C] define different voice broadcast contents respectively; bST[A], bST[B] and bST[C] define different risk prompting manners respectively; eCMD[A], eCMD[B] and eCMD[C] define different engineering machinery engine motion forms respectively.

[0090] In the foregoing embodiments, the control system messages BWT=tMSG[A], tMSG[B] and tMSG[C] correspond to risk levels from low to high respectively.

[0091] Wherein:

[0092] When the message BWT=tMSG[A], vST[A] defines that the system plays the voice "operation is risky, please operate carefully"; bST[A] defines that the risk indication module flashes in red at 1 Hz; and eCMD[A] defines that no influence is exerted on the engineering machinery engine.

[0093] When the message BWT=tMSG[B], vST[B] defines that the system plays the voice "operation is risky, please operate carefully"; bST[B] defines that the risk indication module flashes in red at 2 Hz; and eCMD[B] defines that a lower speed message is sent to the engineering machinery.

[0094] When the message BWT=tMSG[C], vST[C] defines that the system plays the voice "collision is about to occur, please stop operation immediately"; bST[C] defines that the risk indication module flashes in red at 3 Hz; and eCMD[C] defines that an engine shutdown message is sent to the engineering machinery.

[0095] In other embodiments, the messages BWT=tMSG[A], tMSG[B] and tMSG[C] can also correspond to risk levels from high to low. The number of levels can also be fewer or more.

[0096] The movement of the engineering machinery can be automatically controlled when the risk level increases, which can more effectively reduce the risk of the engineering machinery touching the high-voltage line than simply prompting the user.

[0097] The designed vehicle-mounted control device is connected to the CAN interface of the engineering machinery through the bridge module in a plug-in manner, so that the vehicle-mounted control device can be directly placed in the engineering machinery cab. In this way, the need for complex modification and installation of the mechanical structure and power supply line of the engineering machinery on site each time and for each engineering machinery near the high-voltage line is avoided, the installation workload, cost and complexity are reduced, and the use convenience and practicality of the system are improved.

[0098] The system can automatically control the change of the engine speed of the engineering machinery according to the risk level, so as to change the movement speed of the engineering machinery and reduce the risk of collision with the high-voltage line. When the risk is very high, the system automatically controls the engineering machinery engine to be turned off, so that the movement of the engineering machinery is stopped, thereby effectively reducing the possibility of the engineering machinery colliding with the high-voltage line, and the safety and practicality of the system are higher than simply prompting the operator.
