Description

Technical Field

[0001] This application relates to the field of power construction equipment technology, and in particular to a distributed all-electric tension machine collaborative control system and method based on a peer-to-peer network. Background Technology

[0002] In the tensioning construction of multi-split conductors for high-voltage transmission lines, multiple tensioning machines are typically used in coordinated operation. An all-electric tensioning machine is a specialized engineering machine driven by a motor, used to apply precise and adjustable tension to conductors, cables, optical fibers, or ropes during installation, ensuring they remain suspended during the laying process and preventing friction with the ground or obstacles. It represents an electrified and intelligent upgrade of the traditional hydraulic tensioning machine.

[0003] However, current overhead line construction methods mostly involve single-machine operation or centralized control of multiple tension machines via a single "central control console." As described in CN114740821B, a "remote centralized control system for synchronous operation of multiple tension machines and traction machines" was proposed. This system relies on a single "central control console" to uniformly command multiple devices. While this approach achieves centralized control, the "central control console" itself becomes a single point of failure risk. If the "central control console" fails, all equipment in the system will be paralyzed. Furthermore, this "central control console" setup requires operators to operate from a designated location, thus lacking flexibility. Summary of the Invention

[0004] The purpose of this application is to provide a distributed all-electric tension machine collaborative control system and method based on a peer-to-peer network, which can realize the decentralization of the system, that is, the global monitoring and operation of the system can be performed on any device, which is of great significance for improving the reliability, flexibility and safety of collaborative operation of multiple tension machines.

[0005] To achieve the above objectives, this application provides the following solution.

[0006] In a first aspect, this application provides a distributed all-electric tension machine collaborative control system based on a peer-to-peer network. The distributed all-electric tension machine collaborative control system includes multiple all-electric tension machines; all all-electric tension machines are connected via a communication network and automatically form a peer-to-peer network when powered on; each of the all-electric tension machines is equipped with a local operation panel, a main controller, and a communication interface; the local operation panel is used by the operator to trigger collaborative operation commands for all all-electric tension machines on the current all-electric tension machine, and to receive and display the operating status data of the remaining all-electric tension machines; the main controller is used to broadcast the collaborative operation commands to the remaining all-electric tension machines via the communication network and to synchronize all all-electric tension machines.

[0007] Secondly, this application also provides a control method for the distributed all-electric tension machine collaborative control system based on a peer-to-peer network as described in the first aspect. The distributed all-electric tension machine collaborative control method based on a peer-to-peer network includes: when all all-electric tension machines are powered on, they are automatically discovered and connected to form a peer-to-peer network using a communication network; the operating status data of all all-electric tension machines are broadcast to the peer-to-peer network according to a preset communication protocol; when an operator presses a collaborative operation button on the local operation panel of any all-electric tension machine, the current all-electric tension machine will generate a collaborative operation instruction with a timestamp, and broadcast the collaborative operation instruction to the remaining all-electric tension machines through the communication network; after all all-electric tension machines are synchronously updated according to the collaborative operation instruction, the updated operating status data of all all-electric tension machines are transmitted back to the peer-to-peer network in real time.

[0008] Based on the specific embodiments provided in this application, the following technical effects are disclosed.

[0009] This application automatically searches for and connects all devices (i.e., all-electric tensioners) via a communication network after they are powered on, thus forming a peer-to-peer network. This eliminates the independent "central control console" found in traditional control modes. Through peer-to-peer network interconnection, each all-electric tensioner can act as the "central control console" for all devices. Simultaneously, operators can perform global monitoring and collaborative operation of all devices from any location and from any networked all-electric tensioner. Therefore, this application achieves decentralized, highly flexible, and highly reliable multi-machine collaborative control, significantly improving the efficiency and safety of multi-split conductor construction.

[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] The purpose of this application is to provide a distributed all-electric tension machine collaborative control system and method based on a peer-to-peer network, which can realize the decentralization of the system, that is, the global monitoring and operation of the system can be performed on any device, which is of great significance for improving the reliability, flexibility and safety of collaborative operation of multiple all-electric tension machines.

[0015] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] In one exemplary embodiment, a distributed all-electric tension machine cooperative control system based on a peer-to-peer network is provided, such as... Figure 1 As shown, the distributed all-electric tension machine collaborative control system based on a peer-to-peer network includes multiple all-electric tension machines.

[0017] Specifically, all fully electric tension machines are connected via a communication network and automatically form a peer-to-peer network when the equipment is powered on; each fully electric tension machine is equipped with a local operation panel, a main controller, and a communication interface.

[0018] Each fully electric tension machine has a local control panel equipped with a display interface and multiple buttons. These buttons are categorized by function, such as start, stop, tension adjustment knob, and emergency brake. When pressed by the operator, these buttons trigger the main controller to generate corresponding commands, such as start, stop, tension adjustment, and emergency brake commands. Furthermore, the operator can input the target tension value on the local control panel's display interface.

[0019] Furthermore, the local control panel is also used by the operator to trigger collaborative operation commands for all fully electric tension machines on the current fully electric tension machine, and to receive and display the operating status data of the remaining fully electric tension machines; the main controller is used to broadcast the collaborative operation commands to the remaining fully electric tension machines through the communication network and to synchronize all fully electric tension machines.

[0020] In one preferred embodiment, the local control panel is also used by the operator to set a uniform target tension value for all all-electric tension machines on the current all-electric tension machine; the main controller is used to broadcast the target tension value to the remaining all-electric tension machines through the communication network, and all all-electric tension machines adjust their tension according to the target tension value.

[0021] As another preferred implementation, the local control panel is also used by the operator to trigger an emergency braking command when a hazard is detected; the main controller is used to broadcast the emergency braking command to the remaining all-electric tension machines via the communication network, and all all-electric tension machines will stop synchronously.

[0022] In another exemplary embodiment, a distributed all-electric tension machine cooperative control method based on a peer-to-peer network is also provided, such as... Figure 2 As shown, the distributed all-electric tension machine cooperative control method based on a peer-to-peer network is as follows.

[0023] Step S1: After all the fully electric tensioners are powered on, they are automatically discovered and connected to form a peer-to-peer network using the communication network.

[0024] In this embodiment, the communication network can be a CAN bus, an industrial Ethernet, or a wireless local area network.

[0025] Step S2: Broadcast the operating status data of all all-electric tensioners to the peer network according to the preset communication protocol.

[0026] In this embodiment, the operating status data mainly includes tension value, speed, battery level, and fault information.

[0027] Step S3: When the operator presses the collaborative operation button on the local operation panel of any all-electric tension machine, the current all-electric tension machine will generate a collaborative operation instruction with a timestamp and broadcast the collaborative operation instruction to the remaining all-electric tension machines through the communication network.

[0028] In one preferred embodiment, when an operator presses the start or stop button on the local control panel of any fully electric tension machine, the main controller of the current fully electric tension machine will generate a start or stop command with a timestamp and broadcast it to the remaining fully electric tension machines through the communication network. All fully electric tension machines will then perform start or stop actions according to the corresponding command.

[0029] As another preferred implementation, when the operator inputs or sets a uniform target tension value for all all-electric tension machines on the local operation panel of any all-electric tension machine or through the tension adjustment knob, the main controller of the current all-electric tension machine broadcasts the target tension value to the remaining all-electric tension machines through the communication network, and all all-electric tension machines adjust their tension according to the target tension value.

[0030] Step S4: After all the all-electric tensioners have been synchronously updated according to the collaborative operation instructions, the updated operating status data of all the all-electric tensioners is transmitted back to the peer network in real time.

[0031] Based on the above steps, the method of this embodiment can be divided into several parts: system networking, global monitoring, coordinated start-up and shutdown, tension coordination, emergency response, and status feedback. Each part is detailed below.

[0032] System networking: After all the fully electric tensioners are powered on, they are automatically discovered and connected through the communication network to form a peer-to-peer network.

[0033] Global monitoring: All all-electric tension machines periodically broadcast their operating status data (tension value, speed, battery level, fault alarm, etc.) to the peer network according to a preset communication protocol; the operator on any all-electric tension machine can receive and display the status data from all other all-electric tension machines in the peer network through the local operation panel, thereby realizing real-time global monitoring.

[0034] Coordinated Start-Stop: When an operator presses the "Start" or "Stop" button on the local control panel of any fully electric tension machine, the main controller of that machine generates a timestamped control command and broadcasts it to all other fully electric tension machines via the communication network; the main controllers of all fully electric tension machines that receive the command immediately execute the corresponding start or stop action to ensure synchronous response.

[0035] Tension coordination: The operator sets a uniform target tension value on any fully electric tension machine, and this value is broadcast to all fully electric tension machines, which then adjust their output tension synchronously.

[0036] Emergency Response: When the operator of any fully electric tension machine issues an "emergency stop" command, the command is broadcast to all fully electric tension machines, and all fully electric tension machines immediately perform emergency braking.

[0037] Status feedback: All fully electric tensioners transmit their operating status back to the peer network in real time for monitoring by other devices.

[0038] In summary, this application has the following main advantages.

[0039] (1) Decentralization: This application eliminates the independent "master control unit" or "central control console", and all devices are equal in status.

[0040] (2) Global monitoring: Operators can monitor the operating status of other all-electric tension machines in real time on any networked all-electric tension machine.

[0041] (3) Collaborative operation: Operators can perform unified start-up, shutdown, tension adjustment and other collaborative operations on all equipment on any networked all-electric tension machine.

[0042] (4) High reliability: There is no single point of failure, and the failure of any device will not cause the entire system to be paralyzed.

[0043] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
