Description

Technical Field

[0001] The present invention relates to the technical field of generators, and in particular to a remote control method and system for a self-propelled generator device. Background Art

[0002] With the growing global demand for renewable energy and temporary power supply, generator sets, especially vehicle-mounted generator sets, are widely used in many fields such as field engineering, construction, and disaster emergency response. In these scenarios, generator sets not only need to provide stable power efficiently, but also must have the ability to adapt to complex environments. In addition, with the continuous advancement of technology, automation, remote monitoring and intelligent control have become the key directions for the development of generator set systems. The efficient operation, intelligent control and safety assurance of generator sets play a vital role in improving equipment availability, reducing manual intervention and reducing the risk of failure.

[0003] In the existing technology, although a variety of remote control technologies have been applied to the monitoring and management of generator sets, most existing control systems still have many problems. Traditional remote control technologies for generator sets usually rely on a single monitoring method, such as data transmission and status monitoring of the unit through traditional communication protocols, but these technologies cannot effectively cope with the rapid dispatch and safety management of equipment in complex environments or harsh conditions. For example, in the event of strong environmental interference (such as high temperature, excessive wind speed, etc.) and equipment failure, the traditional system has a slow response speed and cannot adjust the equipment operation strategy in real time, resulting in the equipment being unable to operate within a safe range, increasing the risk of failure.

[0004] In view of this, it is necessary to improve the remote control technology of the generator device in the prior art to solve the technical problem of slow response of its safety management. Summary of the invention

[0005] The purpose of the present invention is to provide a remote control method and system for a self-propelled generator device to solve the above technical problems.

[0006] To achieve this object, the present invention adopts the following technical solutions: A remote control method for a self-propelled generator device comprises the following steps: S1, when the main control unit is started, a virtual mirror system is synchronously generated, and the preset parameter model is loaded through the 5G-MEC edge computing node. The electronic control unit of each generator device executes the three-level self-test program and uploads the self-test data packet through the OPC UA protocol.

Among them, 5G-MEC edge (5G MobileEdge Computing, 5G mobile edge computing): edge computing technology in 5G networks, deploys computing resources at the edge of the network close to users to reduce latency and improve data processing efficiency.

[0024] S2, the environmental perception stage, builds a three-dimensional environmental model through a multi-spectral detection device, establishes a temperature field distribution map by combining infrared thermal imaging technology, calculates the optimal movement path using an improved path planning algorithm, and dynamically adjusts the energy consumption model based on environmental parameters.

[0027] The working principle of the present invention is as follows: first, the main control unit synchronously generates a virtual mirror system at startup, loads a preset parameter model in combination with the 5G-MEC edge computing node, and performs self-inspection on each generator device to ensure that the equipment is in a good state; then, in the environmental perception stage, an environmental model is constructed through multi-spectral detection and infrared thermal imaging technology, and an improved path planning algorithm is used to dynamically adjust the energy consumption model in combination with environmental parameters to optimize the driving path and energy efficiency; then, during the equipment deployment process, the lifting mechanism is adjusted through force feedback control to ensure that the equipment is smoothly detached, and the support mode is automatically switched according to the geological characteristics. In the operation control stage, a hierarchical communication network architecture and a dynamic load balancing algorithm are used to ensure the reasonable allocation of power generation tasks and the effective collaboration between various devices, thereby improving the overall operating efficiency; an efficient, safe and intelligent generator set control solution is provided.

[0028] In this embodiment, specifically, step S1 specifically includes the following steps: S11. When the main control unit starts, it calls the preset device digital twin model library and constructs a virtual mirror system locally through the distributed computing resources of the 5G-MEC edge computing node. The virtual mirror system includes a mechanical structure dynamics model, an electrical system simulation model, and a communication network topology model; the model accuracy reaches over 95%.

[0029] S12. Establish a dedicated transmission channel through 5G network slicing technology and download the latest parameter configuration file from the cloud server. The configuration file includes device operation historical data, environment adaptation parameters, and a fault feature library; the size of the configuration file is controlled within 10MB, and the transmission delay is less than 50ms.

[0030] S13. Each generator set electronic control unit starts a parallel self-check program and performs three-level detection: The first-level detection of the mechanical system includes collecting hydraulic pressure values (range 0 - 30MPa), vibration acceleration (threshold < 0.5g), and displacement sensor data; the second-level detection of the electrical system includes measuring insulation resistance (standard value > 10MΩ), winding temperature (threshold < 120°C), and output voltage volatility (< ±2%); the third-level detection of the communication system includes testing network delay (< 100ms), packet loss rate (< 0.1%), and signal strength (> -85dBm).

[0031] S14. The electronic control unit structurally encapsulates the self-check data according to the OPC UA information model. The data packet contains a timestamp, device ID, detection item code, and measured value, and uses the AES-256 encryption algorithm for data encryption, and uploads it to the main control unit through the 5G network. The single-transmission data volume is controlled within 1KB. OPC UA is an industrial communication protocol used to achieve secure and reliable data exchange between devices.

[0032] S15. After receiving the self-check data packet, the main control unit calls the virtual mirror system for real-time simulation calculation, compares and analyzes the measured value with the simulation prediction value, and calculates the deviation rate of each parameter. The deviation rate calculation formula is: Δ = (|measured value - predicted value| / range) × 100%.

[0033] S16. Based on the fuzzy comprehensive evaluation algorithm, perform weighted calculation on the detection results of the mechanical, electrical, and communication dimensions of the three-level detection. The weight coefficients are 0.4, 0.35, and 0.25 respectively to generate the device health index HHI. The value range of HHI is 0 - 1. When HHI > 0.8, it is determined to be in a healthy state; when 0.5 < HHI ≤ 0.8, it prompts an attention state; when HHI ≤ 0.5, it triggers an alarm.

[0034] S17, writes the health assessment results into the blockchain distributed ledger, uses smart contract technology to achieve tamper-proof storage of assessment data, and synchronizes the assessment results to the cloud digital twin platform through the 5G network for subsequent equipment performance optimization analysis.

[0035] In this embodiment, it is specifically explained that step S2 specifically includes the following steps: S21 uses a multispectral LiDAR sensor to scan the working environment, collect terrain elevation data, obstacle distribution information and surface features, with a scanning frequency of 10Hz, and build a three-dimensional point cloud map. Among them, the multispectral LiDAR sensor (Light Detection and Ranging) is a remote sensing technology that measures distance through laser pulses and is used to build a three-dimensional environmental model.

[0036] S22, the infrared thermal imaging module collects ambient temperature data in real time. The temperature measurement range is -20℃ to 300℃. It generates a temperature gradient field distribution map in combination with the thermal radiation model to identify high-temperature heat source areas and mark the danger level.

[0037] S23, using the improved A* path planning algorithm, combined with the three-dimensional point cloud map and temperature gradient field data, calculates the optimal moving path. The path planning objective function is: E = α·distance + β·slope + γ·thermal radiation attenuation coefficient, Among them, α, β, and γ are weight coefficients, which are 0.6, 0.3, and 0.1 respectively.

[0038] S24, dynamically adjust the energy consumption model based on environmental parameters, and calculate the mobile energy consumption in real time. The energy consumption calculation formula is: P = k1·v + k2·m·g·sinθ + k3·T, Where v is the moving speed, m is the mass of the device, θ is the slope angle, T is the ambient temperature, and k1, k2, and k3 are correction coefficients.

[0039] S25 uploads environmental perception data to the main control unit through the 5G network. The data packet contains three-dimensional map data, temperature field distribution map and path planning results. The compression algorithm is used to control the data packet size within 5MB, and the transmission delay is less than 100ms.

[0040] S26, the main control unit generates a movement instruction based on the environmental perception result, and sends it to the self-propelled mechanism 30 through the time-sensitive network. The control device moves along the planned path, and the dynamic adjustment range of the movement speed is 0.1m / s-1.5m / s to ensure a balance between safety and efficiency.

[0041] In this embodiment, it is specifically explained that step S3 specifically includes the following steps: S31, when the lifting mechanism 40 is started, the six-axis force sensor monitors the pressure distribution of the contact surface in real time to obtain mechanical parameters; the pressure measurement range is 0-50kN, and the acquisition frequency is 100Hz, to ensure the mechanical stability of the separation process; S32, a fuzzy PID controller is used to dynamically adjust the hydraulic output to control the movement speed of the lifting mechanism 40; the speed adjustment range is 0.05-0.2m / s, ensuring that the vibration acceleration during the separation process is ≤0.3g; wherein, the fuzzy PID controller (Proportional-Integral-Derivative) is a commonly used control algorithm used to adjust the output of the system to achieve the desired target value.

[0042] S33, scans the geological features of the landing area and measures the surface hardness parameters. The hardness measurement range is 0-100MPa, with an accuracy of ±1MPa, and can identify soft soil, hard ground or slope terrain.

[0043] S34, automatically switches the support mode according to the surface hardness parameters: rigid support pads are used in hard ground mode, extended support plates are used in soft soil mode, and adaptive leveling mechanism is enabled in slope terrain to ensure the stability of the device.

[0044] S35, uploads the mechanical parameters and surface hardness parameters to the main control unit through the 5G network. The main control unit monitors the separation process in real time. When abnormal mechanical parameters are detected, the emergency stop command is immediately triggered to ensure safe separation.

[0045] S36, after the separation is completed, the main control unit generates a deployment completion signal and uploads the deployment status data to the cloud digital twin platform through the OPC UA protocol for subsequent operation monitoring and optimization.

[0046] In this embodiment, it is specifically explained that step S4 specifically includes the following steps: S41, establish a two-layer communication network architecture: the first layer is the communication link between the main control unit and the generator set, using a time-sensitive network to transmit control instructions, with a transmission delay of less than 10ms and a packet loss rate of <0.01%; the second layer is the communication link between the generator sets, using LoRa self-organizing network technology, with a transmission distance of up to 5km and power consumption less than 100mW. LoRa (Long Range): a low-power wide area network communication technology.

[0047] S42, the main control unit allocates power generation tasks through a dynamic load balancing algorithm, and the task allocation formula is: P_alloc = (C_i·HHI_i) / (Σ(C_j·HHI_j))×P_total, Where C_i is the real-time capacity factor of the i-th generator set, HHI_i is the equipment health index of the i-th generator set, C_j is the real-time capacity factor of the j-th generator set, HHI_j is the equipment health index of the j-th generator set, and P_total is the total load demand.

[0048] For example: the rated capacity of a unit is 100kW. If the current maximum output power is 80kW due to ambient temperature or equipment aging, then its C_j = 0.8 (ratio form) or C_j = 80kW (absolute value form).

[0049] The numerator (C_i·HHI_i) represents the comprehensive weight of the real-time capacity (C_i) and health status (HHI_i) of the i-th unit. The larger the value, the higher the priority of the assigned task.

[0050] The denominator Σ(C_j·HHI_j) is the weighted sum of the real-time capacity and health status of all units (j=1,2,...,n). The function of the denominator is normalization to ensure that the total allocation ratio of all units is 100%.

[0051] S43, each generator set collects operating data in real time, including output voltage (range 0-400V, accuracy ±0.5V), output current (range 0-100A, accuracy ±0.1A) and frequency (range 50±0.2Hz), and uploads it to the main control unit through the OPC UA protocol.

[0052] S44, the main control unit performs real-time analysis of the operating data. When a parameter abnormality is detected, a three-level response strategy is triggered: local power reduction operation in case of yellow warning, isolation of the faulty unit and activation of the backup unit in case of orange warning, and execution of the emergency shutdown protocol in case of red warning.

[0053] S45 records operating data and fault events through blockchain technology, and uses smart contracts to achieve tamper-proof storage of data, ensuring the traceability of the operating process.

[0054] S46, the main control unit regularly generates operation reports, which include power generation efficiency, equipment health status and fault statistics, and are uploaded to the cloud platform through the 5G network for optimizing operation strategies and maintenance plans.
