Description

Technical Field

[0001] This invention relates to a remote-controlled cabin multi-power intelligent management system and method, belonging to the technical field of excavating machinery and equipment. Background Technology

[0002] Excavators, as important engineering machinery, play a vital role in emergency rescue. However, during emergency rescue operations, excavators may encounter situations such as landslides that endanger the operator's life. Remote control systems have emerged to address this need. The operator controls the excavator from a remote control cabin (in a safe area), keeping the operator away from dangerous environments such as landslides and collapses. The remote control cabin requires an external power source, primarily through three methods: AC mains power, a diesel generator, or a battery. Currently, power selection and switching are entirely manual, lacking automatic switching between different power circuits. Safety and reliability need further improvement. Furthermore, the unstable outdoor environment, with its potential for extreme temperatures, humidity levels, and vibrations, causes switching delays and limited environmental adaptability with current power supply systems. Summary of the Invention

[0003] The purpose of this invention is to provide a remote-controlled cabin multi-power intelligent management system and method. By real-time sensing and fusion analysis of the status and environmental parameters of multiple power circuits, it realizes intelligent switching and interlocking protection of power circuits, thereby improving the reliability, intelligence and adaptability of power switching in field emergency rescue scenarios.

[0004] To achieve the above objectives / to solve the above technical problems, the present invention is implemented using the following technical solution.

[0005] On one hand, the present invention provides a remote-controlled cabin multi-power intelligent management system, comprising:

[0006] The power supply box is used to connect to each power circuit and provide power input to the remote control cabin;

[0007] The power detection module is used to collect the status parameters of each power circuit and send them to the controller.

[0008] The environmental sensing module is used to collect environmental parameters around the remote control cabin and send them to the controller;

[0009] The controller is used to control the relays in the power supply box to select and switch power supply circuits based on the received status parameters and environmental parameters of each power supply circuit, combined with a preset switching strategy, while realizing electrical and program interlocking between different power supply circuits in the power supply circuit.

[0010] Furthermore, the power supply circuit includes: a mains power circuit, a diesel generator circuit, and a removable and replaceable battery.

[0011] The mains power circuit and the diesel generator circuit are respectively used to connect to the power supply box as the main power source to provide power input to the remote control cabin;

[0012] The battery is used to power the controller and as a backup power source when there is no external power supply.

[0013] Furthermore, it also includes a network module and a display. The network module is used to receive weather forecasts and warning information pushed from the cloud. The controller uses the weather forecasts and warning information as the basis for adjusting the preset switching strategy. The display is communicatively connected to the controller and is used to display the status of the management system.

[0014] Furthermore, the power detection module includes:

[0015] The mains voltage monitoring unit is used to detect the voltage stability of the mains circuit.

[0016] The diesel generator monitoring unit is used to detect the remaining fuel level and engine speed.

[0017] The battery SOC estimation unit is used to estimate the remaining battery capacity.

[0018] Furthermore, the environment perception module includes:

[0019] Temperature and humidity sensors are used to collect ambient temperature and humidity.

[0020] Vibration sensors are used to collect the intensity of environmental vibrations.

[0021] Secondly, the present invention provides a multi-power intelligent management method for a remote-controlled cabin, applied to the aforementioned multi-power intelligent management system for a remote-controlled cabin, comprising the following steps:

[0022] S1: After the system is powered on and initialized, the power circuit status parameters are collected in real time through the power detection module and the environmental parameters around the remote control cabin are collected through the environmental perception module.

[0023] S2: Determine the available power supply circuits based on the power supply circuit status parameters, and calculate the environmental risk coefficient in conjunction with environmental parameters;

[0024] S3: Based on the comparison between the environmental risk coefficient K and the preset threshold, execute the corresponding power supply strategy, specifically including:

[0025] When K ≤ the first threshold, the mains power circuit is used for power supply, the diesel generator circuit is in standby mode, and the battery is float charged.

[0026] When the first threshold < K ≤ the second threshold, the mains power circuit is used as the primary power source, and the diesel generator circuit is preheated for backup.

[0027] When K > the second threshold, the mains circuit is prohibited, the diesel generator circuit is started and its continuous running time is limited, and the battery discharge cut-off voltage is adjusted.

[0028] Wherein: the first threshold is 2.0, and the second threshold is 3.5.

[0029] Furthermore, during system power-on initialization, all external power supply circuits are disconnected, and cloud-based meteorological and vibration warning information is received during the operational phase to adjust strategies, specifically including:

[0030] Obtain weather forecasts and vibration warnings for the current work area through the network module;

[0031] If extreme weather information or vibration warning information is received, the controller will automatically adjust the current power supply strategy to high-risk mode, giving priority to the combination of battery and diesel generator power supply, and prohibiting the use of mains power circuit;

[0032] If no extreme weather information or vibration warning information is received, the power supply switch shall be performed in accordance with the strategy in step S3.

[0033] Furthermore, the formula for calculating the environmental risk coefficient is as follows:

[0034] K = αT + βH + γV;

[0035] Where: K is the environmental risk coefficient, T is the temperature, H is the humidity, V is the vibration warning information intensity, and α, β, and γ are adjustable weighting coefficients.

[0036] Furthermore, when only the diesel generator circuit and the battery are detected as available in the power supply circuit status parameters, the local maximum survival time strategy is adopted for power supply load allocation, and the maximum power supply duration is calculated as follows:

[0037] ;

[0038] in, For maximum power supply duration, This represents the remaining oil volume. For diesel generator power, Remaining battery capacity Power of electrical equipment This represents the maximum power supply duration; the two parts of the maximum power supply duration correspond to the duration of power supply from the diesel generator and the battery, respectively.

[0039] Furthermore, during the power supply process, the status of each circuit or environmental parameters is monitored in real time, and real-time circuit switching control is performed based on the parameters, specifically including:

[0040] Operational status monitoring: Real-time acquisition of diesel generator speed and synchronous monitoring of output voltage stability. If abnormal speed or excessive voltage fluctuation occurs, the system will immediately send feedback to the controller and trigger temporary load switching.

[0041] Fault warning and monitoring: The controller monitors the operating temperature and oil pressure of the diesel generator in real time. If any parameter exceeds the preset safety threshold, it is judged as a potential fault and the battery backup power is activated in advance to avoid sudden shutdown.

[0042] Vibration Trigger Switching: If the vibration intensity is detected to exceed the preset vibration warning threshold, a vibration warning is triggered, and the controller immediately cuts off the diesel generator power supply circuit, switching all loads to battery power supply; after the vibration intensity drops below the preset vibration recovery threshold, the controller automatically restores the diesel generator power supply or maintains the battery power supply based on the remaining fuel level and battery SOC status.

[0043] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention monitors the status of multiple power supply circuits such as mains power, diesel generator, and storage battery in real time, realizes automatic switching of power supply circuits and electrical and program dual interlocking, and avoids delays and errors caused by manual operation; The present invention collects environmental parameters such as temperature, humidity, and vibration in real time, and combines cloud-based meteorological and vibration early warning information to dynamically adjust the power supply strategy, which significantly improves the adaptability and safety of the system in harsh environments.

[0044] This invention employs an environmental risk coefficient to integrate multi-dimensional environmental data, enabling hierarchical control of the power supply strategy. This allows the system to maintain the optimal power supply mode under different risk levels. When only the diesel generator and battery remain, a maximum survival time strategy is adopted to rationally allocate the load and extend the power supply duration, thereby improving the remote control cabin's continuous operation capability under extreme conditions. Furthermore, through multiple protection mechanisms such as operational status monitoring, fault early warning monitoring, and vibration-triggered switching, closed-loop control of the power supply process and early intervention for faults are achieved, further enhancing the system's reliability and safety.

[0049] It should be noted that:

[0050] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations thereof. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0051] The term "and / or" simply describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0052] Example 1

[0053] like Figure 1 As shown, this embodiment provides a remote control cabin multi-power intelligent management system, including a power supply box, an anti-interference environment sensing module, a controller, a network module, and a display;

[0054] The power supply box is connected to the mains power circuit, diesel generator circuit, and battery circuit to provide power input to the remote control cabin.

[0055] The controller uses an STM32 series microcontroller to handle data processing and logical decision-making.

[0056] The anti-interference environment sensing module includes a power detection module and an environment sensing module;

[0057] The power detection module includes a mains voltage monitoring unit (detecting the voltage stability of the mains circuit), a diesel generator monitoring unit (detecting the remaining fuel and speed), and a battery SOC estimation unit (estimating the remaining battery charge).

[0058] The environmental sensing module includes a temperature and humidity sensor and a vibration sensor. The temperature and humidity sensor is used to collect ambient temperature and humidity; the vibration sensor is used to collect ambient vibration intensity.

[0059] The network module receives weather and vibration warning information from the cloud via 4G / 5G communication, and the display is used to show the system status in real time.

[0060] When the system is working, the controller controls the relays in the power supply box to select and switch the power supply circuit based on the status parameters of each circuit collected by the power supply detection module and the environmental parameters collected by the environmental perception module, combined with the preset switching strategy. It also realizes electrical interlocking and program interlocking between different power supply circuits to ensure that only one power supply is available to the remote control cabin at any time.

[0061] The electrical interlock is achieved through relay contacts connected in series, that is, the normally closed contacts of the mains circuit relay, generator circuit relay, and battery circuit relay are connected in series in each other's circuits to ensure that at any given time, only one circuit's relay coil is energized. The program interlock is achieved through logic judgment within the controller. Before outputting a control signal, the controller first reads the status of all power circuits and determines whether any other circuit is currently powered. Only when it is confirmed that no other circuit is currently powered will the controller output a closing command to the relay of the target circuit.

[0062] The battery serves as a backup power source, supplying power to the entire remote control cabin system when there is no mains power or external power source such as a diesel generator. At the same time, to ensure the continuous operation of the controller, the battery also provides uninterrupted low-voltage auxiliary power to the controller.

[0063] Example 2

[0064] like Figures 2 to 4 The embodiment shown is based on the system of embodiment 1, and provides a multi-power intelligent management method for a remote-controlled cabin, respectively corresponding to... Figure 2 , Figure 3 and Figure 4 The power supply modes shown specifically include:

[0065] like Figure 2 As shown, the power supply mode is a combination of mains power, diesel generator, and battery.

[0066] After the system is powered on and initialized, it first performs a self-test and obtains weather information and vibration warning information from the cloud.

[0067] If extreme weather and vibration warnings are received, the normal power supply judgment process will begin, as follows:

[0068] The system is based on real-time acquisition of power circuit status parameters and environmental parameters. The controller determines the available power circuits based on the power circuit status parameters and calculates the environmental risk coefficient K based on the environmental parameters. The expression for K is:

[0069] K = αT + βH + γV;

[0070] Where K is the environmental risk coefficient, T is the temperature, H is the humidity, V is the vibration warning information intensity, and α, β, and γ are adjustable weighting coefficients;

[0071] As shown in Table 1 below, the temperature and humidity need to be normalized, and the normalized values ​​are between 0 and 1.

[0072] The vibration warning information intensity V is a comprehensive value, which comes from: first, the real-time vibration acceleration peak value (unit: g) collected by the vibration sensor in the environmental perception module, which is normalized to obtain a value between 0 and 1; second, the early warning information of earthquakes, debris flows, landslides, etc. received through the network module.

[0073] Table 1: Temperature and Humidity Normalization Rules

[0074]

[0075] K represents the environmental risk coefficient design principle:

[0076] 1: Total matching threshold: α+β+γ≤3.5 (ensuring that the maximum value of K does not exceed the high-risk threshold);

[0077] 2. On-site adjustments can be made according to the environment without changing the logical rationality;

[0078] 3: α=0.8 (temperature weight) β=1.2 (humidity weight) γ=1.5 (vibration warning weight) Total weight sum: 0.8+1.2+1.5=3.5: K maximum value = 3.5, just triggering the high risk threshold.

[0079] The controller makes power supply strategy decisions based on the K value and a preset threshold:

[0080] When K≤2.0, the risk is low and the mains power supply is prioritized. The mains power supply is used to power the main load, while the battery is float-charged. The diesel generator remains in standby mode, and the system enters the mains power supply cycle, continuously monitoring the mains power status.

[0081] When 2.0 < K ≤ 3.5, it is judged as medium risk, and the mains power circuit is used as the primary power source, while the diesel generator circuit is preheated and kept as a backup.

[0082] When K > 3.5, a high-risk condition is identified, the use of the mains power circuit is prohibited, the diesel generator circuit is started and its continuous operation time is limited, and the battery discharge cutoff voltage is increased by 0.2V. If the original discharge cutoff voltage of the battery is 21.6V (corresponding to 2.7V for a single lithium battery cell), the increased voltage is 21.8V. This adjustment is achieved by the controller sending a command to the Battery Management System (BMS) to modify the discharge protection parameters set in the BMS, thereby reducing the depth of discharge of the battery in harsh environments and ensuring its lifespan and safety.

[0083] If an abnormality in the mains power supply is detected during the mains power supply process (such as voltage fluctuation exceeding the limit: mains voltage ≥180V for 3 seconds or power failure), the controller will immediately perform a switchover; firstly, the mains power relay will be disconnected, and the diesel generator relay will be quickly started and closed according to the status of the diesel generator (whether it has been preheated), so that the diesel generator can take over the power supply, while determining whether the battery can be charged.

[0084] If the controller detects that the mains voltage is fluctuating around 185V while the diesel generator circuit is in standby mode and the mains voltage is maintained as the primary power source, the controller will issue an early warning and increase the diesel generator speed to 1200rpm. If the mains voltage remains ≥180V for 3 seconds, the controller will immediately switch over and the diesel generator will take over the power supply.

[0085] If a vibration intensity exceeding a preset threshold (e.g., ≥5g, where g is the acceleration due to gravity) is detected during continuous operation of the diesel generator circuit, a vibration warning is triggered, and the controller immediately cuts off the diesel generator power supply circuit, instantly switching all loads to battery power.

[0086] Mains power restoration switching: During diesel generator or battery power supply, the controller continuously monitors the mains power status; once the mains power is detected to be restored to normal and stable, and the environmental risk factor is reduced, the system will prioritize switching back to mains power supply mode.

[0087] like Figure 3 As shown, the diesel generator and battery work together to provide power.

[0088] This mode is typically enabled when there is no mains power supply or when mains power is disabled by "high-risk mode".

[0089] When the system detects that only the diesel generator circuit and the battery are available, the local maximum survival time strategy is used for power load allocation. The maximum power supply duration is calculated using the following expression:

[0090] ;

[0091] in, For maximum power supply duration, This represents the remaining oil volume. For diesel generator power, Remaining battery capacity Power of electrical equipment This is the maximum power supply duration;

[0092] when When the SOC is greater than 30% and the SOC is greater than 60%, the power supply is shared equally by the diesel generator and the battery to balance the losses.

[0093] When 15% < When the fuel level is ≤30%, the battery will provide power to reduce diesel fuel consumption.

[0094] When SOC ≤ 30%, a diesel generator provides power, and a reserved battery is provided as an emergency power source.

[0095] During the diesel generator power supply process, if the controller detects that the operating status is normal and the voltage fluctuation is ≤5% and the ambient vibration intensity is ≤2g, then the diesel engine will continue to supply power alone.

[0096] If the controller detects an abnormal operating status and voltage fluctuation >5% or ambient vibration intensity ≥5g, it will trigger a temporary load switch, with the battery providing power independently.

[0097] like Figure 4 As shown, battery-only power supply mode

[0098] This mode is enabled when there is no mains power, the diesel generator is unavailable (e.g., due to malfunction or lack of fuel), or both are disabled.

[0099] When the controller detects that there is no available external power source (both AC power and diesel generator are unavailable) and the battery SOC is higher than its minimum discharge cutoff voltage threshold Z, the system enters the battery-only power supply mode.

[0100] The controller closes the battery relay, and the battery supplies power to the main load of the remote control cabin.

[0101] Power saving management: During battery power supply, the controller will estimate the remaining power supply time in real time and can send frequency reduction or shutdown commands to non-critical equipment (such as some displays, air conditioners, etc.) in the remote control cabin according to the preset power saving strategy to extend the power supply time of critical equipment.

[0102] The controller continuously monitors the battery's SOC. When it reaches the preset critical discharge cutoff voltage, the system issues a final warning and automatically disconnects the main load relay before the voltage drops below the safety threshold. It then maintains only the controller's own minimum power consumption operation to protect the battery from deep discharge damage and waits for the external power supply to be restored.

[0103] If an extreme weather or vibration warning is received, the controller will automatically adjust the power supply strategy to high-risk mode, prioritizing the use of a combination of battery and diesel generator power supply and prohibiting the use of mains power circuit; cloud-based warning information has the highest priority. Once an extreme weather or vibration warning is received, the system will be forced into high-risk mode until the warning is lifted; after the warning is lifted, the system will then execute the corresponding normal power supply strategy based on the real-time environmental risk coefficient K value.

[0104] This embodiment has the following functions:

[0105] Operational status monitoring: During power supply, the system monitors the status and environmental parameters of each circuit in real time: The diesel engine speed monitoring unit collects the diesel generator speed in real time (normal operating speed range is 1500-2000 rpm) and monitors the output voltage stability (allowable fluctuation range ±5%). If abnormal speed or excessive voltage fluctuation occurs, the system will immediately trigger temporary load switching.

[0106] Fault warning and monitoring: The controller monitors key parameters such as the operating temperature and oil pressure of the diesel generator in real time. If they exceed the safety threshold, it is judged as a potential fault and the battery backup power supply is activated in advance.

[0107] Vibration Trigger Switching: If the vibration sensor detects that the vibration intensity exceeds the preset vibration warning threshold (e.g., ≥5g), a vibration warning is triggered, and the controller immediately cuts off the diesel generator power supply circuit, switching all loads to battery power supply; after the vibration intensity drops to a safe range (e.g., ≤2g), the diesel generator power supply is automatically restored or the battery power supply is maintained based on the remaining fuel level and battery SOC status.

[0108] Through the aforementioned multiple monitoring and switching mechanisms, this embodiment enables the system to achieve intelligent management and highly reliable power supply for multiple power supply circuits.

However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the protection scope of the present invention.
