Abstract
Description
Technical Field
[0001] This application relates to the field of intelligent power distribution technology, and in particular to a power distribution system and its control method, control device and vehicle. Background Technology
[0002] During the use of a motorhome, the intelligent management of its water and electricity systems is crucial for the user. Generally speaking, a motorhome power system includes stages such as "power generation, energy storage, power transformation, power transmission, and power consumption," with each stage involving one or more electrical devices, and each electrical device having different control switches.
[0003] Therefore, each electrical device requires independent wiring, and users need to rely on a large number of connecting wires (such as power cords and communication lines) to build the energy system control. This wiring is complex, costly, and occupies a significant amount of vehicle interior space. Actual installation is cumbersome, and electrical safety cannot be guaranteed. Furthermore, each electrical device (such as a refrigerator, microwave oven, light, and water pump) requires independent control, and control switches may be distributed in different areas, making centralized control impossible.

[0032] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application.
[0033] This application provides a power distribution system that can be applied to vehicles, such as motorhomes, refrigerated trucks, or other vehicles with energy systems. Figure 1 As shown, the power distribution system 100 includes: Interactive device 10 is adapted to be connected to power distribution equipment 20 via a first communication link and is configured to receive user operation commands for implementing load control and output load control commands corresponding to the user operation commands. Power distribution equipment 20, including: Power port 21 is configured to receive input power from external power source 60; Several power distribution channel modules 22, each power distribution channel module 22 is connected to a power port 21 and at least one load 50 respectively; Control module 23 is configured to determine the corresponding power distribution control signal according to the load control command, so that power distribution channel module 22 adjusts the load 50 connected to the power distribution channel module 22 to the target working state in response to the power distribution control signal.
[0034] As a specific example, the interactive device 10 may include at least one of a display screen, a touch screen, and physical buttons, and can be installed in the living quarters of a motorhome, allowing users to operate the interactive device 10 when they need to control the water and electricity systems. In a preferred embodiment, the interactive device 10 is a touch screen, on which users can operate and access information such as device status displayed on the touch screen.
[0035] The first communication link may include a bus 30, which may include at least one of RS485, RS232, CAN, etc. In this case, the interactive device 10 itself has a communication module, which can be directly connected to the power distribution equipment 20 (e.g., a distribution box) through the bus 30, thereby realizing communication between the interactive device 10 and the power distribution equipment 20. Alternatively, the first communication link may include a wireless communication link and the bus 30. The wireless communication link may include at least one of Wi-Fi Direct and Bluetooth, and the bus 30 may include at least one of RS485, RS232, CAN, etc. In this case, the interactive device 10 can first connect to the local gateway 40 through the wireless communication link, and the local gateway 40 can then connect to the power distribution equipment 20 through the bus 30, thereby realizing communication between the interactive device 10 and the power distribution equipment 20. Therefore, the power distribution equipment 20 can be installed in a concealed location in the living compartment. Users do not need to directly operate the power distribution equipment 20; they can control the power distribution equipment 20 by operating the interactive device 10, thus avoiding the safety hazards caused by users coming into contact with the high-power electricity on the power distribution equipment 20.
[0036] As a specific example, the interactive device 10 is also suitable for connecting to a user terminal via a second communication link. The user terminal may include at least one of a mobile phone, tablet computer, and smartwatch. For example, the second communication link may include a wireless communication link, which may include at least one of Wi-Fi Direct and Bluetooth. In this case, the mobile phone can connect to the interactive device 10 via the wireless communication link to achieve local wireless control. Alternatively, the second communication link may include a data communication link and a bus 30. The bus 30 may include at least one of RS485, RS232, and CAN. In this case, the mobile phone can access a cloud server via the data communication link. The cloud server can connect to an in-vehicle 3G / 4G / 5G router, which can connect to a local gateway 40. The local gateway 40 can then connect to a display screen via the bus 30, thereby enabling the user to remotely and wirelessly control the power distribution equipment via the user terminal.
[0037] As a specific example, user operation instructions can be input directly by the user on the interactive device 10 (e.g., a touchscreen or physical button), or they can be input by the user through a user terminal (e.g., a mobile phone, tablet, or smartwatch) and obtained through the second communication link. After obtaining the user operation instruction, the interactive device 10 generates a corresponding load control instruction based on the user operation instruction and sends it to the power distribution equipment through the first communication link, thereby enabling the power distribution equipment to perform the corresponding load control.
[0038] As a specific example, the power port 21 of the power distribution equipment 20 may include at least one of a DC power input port and an AC power input port. Accordingly, the input power includes DC input power and AC input power. The DC power input port can be configured to receive DC input power, and the AC power input port can be configured to receive AC input power. The DC input power can come directly from an external power source 60, which may be the vehicle's battery system; alternatively, the vehicle's battery system can be connected to the DC power input port via a DC-DC converter, which converts the DC power output from the battery system with a first voltage value into DC power with a second voltage value and provides it to the DC power input port. The AC input power can come from an inverter, which can be connected to the vehicle's battery system and converts the DC power from the battery system into AC power and provides it to the AC power input port.
[0039] As a specific example, the DC power input port may include two terminals, BAT+ (red) and BAT- (black), for connecting the positive and negative terminals of the vehicle's battery system. The battery system can be a 12V or 48V rechargeable battery, supporting a maximum input current of 100A. The DC power input port may also be configured with a DC voltage detection circuit for detecting the DC input voltage. The DC voltage detection circuit can detect a voltage range of 0-60V with an accuracy of ±0.1V to meet the power metering requirements of the DC circuit. In practical applications, if the power distribution equipment 20 also communicates with the battery system, allowing it to obtain the DC input voltage both through communication and by sampling from the hardware DC voltage detection circuit, the DC input voltage obtained through communication is preferred as the reference. The DC power input port can also supply power to the system power supply of the power distribution equipment 20, providing a wide voltage range of 8-60V. Alternatively, the DC power input port may further include a reverse connection protection module to prevent damage to internal components caused by reverse connection of the positive and negative terminals of the input power supply.
[0040] As a specific example, the AC power input port may include three terminals: L, N, and E, for connecting to the output of the inverter and receiving the AC current output by the inverter. The input of the inverter is connected to the vehicle's battery system. As another specific example, the inverter may also have communication capabilities, enabling it to establish a communication connection with the power distribution equipment 20. The AC power input port may also be configured with an AC voltage detection circuit for detecting the AC input voltage (e.g., the accuracy of the AC input voltage can be set to retain one decimal place) to facilitate the calculation of the load power of each circuit. This function allows for the detection of the AC input voltage through hardware circuitry when the AC output voltage of the inverter cannot be obtained through the communication protocol level. In practical applications, if the power distribution equipment 20 can obtain the AC input voltage or the inverter's AC output voltage through communication, or through hardware sampling, the AC input voltage obtained through communication is preferred as the reference.
[0041] As a specific example, the power distribution equipment 20 also includes several power distribution channel modules 22. The input terminal of each power distribution channel module 22 is connected to the power port 21, and the output terminal is connected to the load 50, for controllably supplying the power input from the power port to the load 50. When the load 50 is a DC power load, the power distribution channel module 22 connected to the load is connected to the DC power input port; or, when the load 50 is an AC power load, the power distribution channel module 22 connected to the load is connected to the AC power input port.
[0042] As a specific example, the power distribution equipment 20 also includes a control module 23, which generates a corresponding power distribution control signal based on the received load control command. Optionally, one load control command can generate one or more power distribution control signals. The power distribution control signals are used to control the corresponding power distribution channel module 22. By changing the operating state of the power distribution channel module 22, the power distribution channel module 22 corresponding to the power distribution control signal adjusts the load 50 connected to the power distribution channel module to a target operating state in response to the power distribution control signal. The target operating state of the load 50 can include any one of the on / off state of the load 50 and the operating state of the load 50 under different operating parameters (power, brightness, etc.).
[0043] In this embodiment, a power distribution system including an interactive device and a power distribution device is provided. The power distribution device includes a power port, several power distribution channel modules, and a control module. The interactive device is adapted to connect to the power distribution device via a first communication link. The interactive device is configured to receive user operation commands for load control and output load control commands corresponding to the user operation commands. The control module is configured to determine the corresponding power distribution control signal based on the load control command, so that the power distribution channel modules adjust the loads connected to the power distribution channel modules to the target operating state in response to the power distribution control signal. The power distribution system achieves centralized and unified control of the target operating states of each load, reducing the connection lines required for independent control, lowering wiring costs and reducing the space occupied in the vehicle, simplifying installation, and improving electrical safety. Furthermore, the centralized and unified control of the target operating states of each load by the power distribution system achieves systematic intelligent control of all electrical equipment, improving the intelligence level of the energy system.
[0044] In an alternative implementation, such as Figure 2 As shown, the power distribution channel module 22 includes a controlled switch 221, which is configured to selectively open or close according to a power distribution control signal, thereby adjusting the operating state of at least one load 50 connected to the power distribution channel module 22.
[0045] As a specific example, the power distribution channel module 22 may include at least one of a DC output power distribution channel and an AC output power distribution channel. The DC output power distribution channel is used to distribute the DC input of the DC power input port to the DC load connected to the channel. As a specific example, two types of DC output power distribution channels can be provided: a high-load channel and a low-load channel, where the rated current of the high-load channel can be, for example, 20A, and the rated current of the low-load channel can be, for example, 10A. Figure 3 As shown, each DC output distribution channel can be connected to a fixed or non-fixed DC load 51. The large load channel can be connected to a DC load with a larger power requirement, and the small load channel can be connected to a DC load with a smaller power requirement.
[0046] As a specific example, each DC output power distribution channel may include at least one of a protection element unit 222 and a controlled switch 221. As another specific example, the protection element unit 222 may be a replaceable fuse, with each channel having its own independent protection element unit 222. The protection element unit 222 protects the load connected to that power distribution channel module from overcurrent surges. The controlled switch 221 may be a magnetically latched relay, which reduces system power consumption during conduction. The magnetically latched relay can selectively open or close according to the power distribution control signal output by the control module 23, thereby adjusting the operating state of the load 50 connected to that power distribution channel module.
[0047] The control module 23 also includes a memory that stores the switching states of the controlled switches 221 in each power distribution channel module 22. Upon receiving a load control command, the control module 23 can determine the corresponding power distribution control signal based on the load control command and the switching states of the controlled switches 221 stored in the memory. If the switching state of the controlled switch 221 indicated by the load control command is inconsistent with the switching state of the controlled switch 221 stored in the memory, the corresponding power distribution control signal is output to change the switching state of the controlled switch 221, and the switching state of the controlled switch 221 stored in the memory is updated accordingly. Conversely, if the switching state of the controlled switch 221 indicated by the load control command is consistent with the switching state of the controlled switch 221 stored in the memory, no power distribution control signal needs to be output, and the current switching state of the controlled switch 221 is maintained.
[0048] When power is restored after a system power outage, the magnetic latching relay remains in the OFF state by default, regardless of its state before the power outage. Controlling the on / off state of the magnetic latching relay controls the ON / OFF state of the DC load 51. As a specific example, each DC output power distribution channel may also include an LED indicator. The LED indicator can indicate the on / off state of the DC output power distribution channel. If the channel is on, the LED indicator can display green or be lit; if the channel is off, for example, if at least one of the following occurs: the magnetic latching relay is not conducting, or the fuse is not inserted or is damaged, the LED indicator can display red or be off.
[0049] As a specific example, such as Figure 4 As shown, each AC output power distribution channel may include at least one of a protection element unit 222 and a controlled switch 221. The AC output power distribution channel is used to distribute AC power to AC loads, which may be at least one of 120V and 220V AC loads 54. As a specific example, the protection element unit 222 may be an air switch, with each channel having an independent protection element unit 222, ensuring that damage to one power distribution channel module does not affect other channels. The controlled switch 221 may be a magnetically latched relay. The air switch can be selected based on the rated current of the AC load 54; for example, a 20A air switch is selected to support a 20A AC load. As a specific example, each AC output power distribution channel may also include an AC indicator light. The AC indicator light indicates the on / off status of the AC output power distribution channel.
[0050] As a specific example, load 50 may include at least one of a lighting load and a ventilation fan. The lighting load may include at least one of an awning light, an ambient light, a ceiling light, and a bedside lamp. Control module 23 controls the on / off state of the controlled switch 221 of the power distribution channel module 22 connected to the lighting load, thereby controlling the opening or closing of the lighting load. Control module 23 also controls the on / off state of the controlled switch 221 of the power distribution channel module 22 connected to the ventilation fan, thereby controlling the opening or closing of the ventilation fan. Furthermore, when controlling load 50, the user only needs to perform the corresponding operation on the interactive device 10, without having to control the lighting load and ventilation fan separately at different locations. This makes centralized and unified control of the load's operating status by the power distribution system possible, greatly improving the intelligence of the power distribution and the user experience in the RV.
[0051] In an optional embodiment, the power distribution channel module 22 includes a protection element unit 222 connected to the power port 21. The protection element unit 222 includes a protection element socket and a pluggable protection element coupled to each other. When a peak current occurs in the power distribution channel module 22, the pluggable protection element can melt and disconnect the power distribution channel module 22, thereby protecting the electrical safety of the load 50. Simultaneously, by using a pluggable protection element unit, user replacement and maintenance are convenient, improving the user experience. Each power distribution channel module 22 has an independent protection element unit 222, ensuring that damage to one circuit will not affect the normal operation of other circuits.
[0052] In an alternative implementation, such as Figure 5 As shown, at least one of the power distribution channel modules 22 is used to connect the lamp load 52, which includes a dimming unit 224. The control module 23 is also configured to determine the corresponding dimming control signal according to the load control command, so that the dimming unit 224 adjusts the power output to the lamp load according to the dimming control signal.
[0053] As a specific example, the dimming unit may include a controllable semiconductor switching device. The controllable semiconductor switching device may include at least one of the following: BJT (transistor), SCR (silicon controlled rectifier), GTO (gate turn-off thyristor), MOSFET (metal-oxide-semiconductor field-effect transistor), IGBT (insulated-gate bipolar transistor), MCT (MOS controlled thyristor), and SIT (static induction transistor).
[0054] As a specific example, the load control command can be generated by the user dragging a slider button on the interactive device 10 to a target position. The control module 23 can determine the corresponding dimming control signal based on the percentage corresponding to the target position of the slider, so that the dimming unit 224 adjusts the power output to the lamp load according to the dimming control signal, thereby adjusting the brightness and / or color of the lamp load.
[0055] As a specific example, for white LED lights (such as ceiling lights in RVs), users can drag the brightness slider button on the monitoring screen to generate user operation commands and send the corresponding brightness control commands to the power distribution equipment 20. Correspondingly, the control module 23 of the power distribution equipment 20 outputs a PWM dimming drive signal with a corresponding duty cycle to the dimming unit 224 according to the brightness control command. The dimming unit 224 can adjust the power output to the lamp load according to the PWM dimming drive signals with different duty cycles, thereby adjusting the brightness of the white LED light. Similarly, for RGB LED lights, they can be dimmed separately through three RGB dimming units to obtain ambient lights of different colors and brightness, thereby realizing centralized and unified control of the lamp load's operating status by the power distribution system and improving the level of intelligence.
[0056] In one optional implementation, the load control command includes a scenario mode trigger command, which is associated with at least one preset power distribution channel module 22; The control module 23 is configured to determine the corresponding power distribution control signal according to the scene mode trigger command, so that at least one preset power distribution channel module 22 responds to the power distribution control signal to adjust the load connected to the preset power distribution channel module 22 to the target working state.
[0057] In an optional embodiment, the scene mode triggering command includes an energy-saving mode triggering command. The control module 23 is further configured to determine a power distribution control signal corresponding to the energy-saving mode triggering command in response to the remaining available power of the external power supply 60 being lower than a preset power threshold, or in response to the voltage of the external power supply 60 being lower than a preset voltage threshold. This causes at least one preset power distribution channel module 22 corresponding to the energy-saving mode triggering command to adjust the load connected to the preset power distribution channel module 22 to the target operating state in response to the power distribution control signal.
[0058] As a specific example, the remaining available power of the external power supply 60 can be obtained from the voltage of the external power supply 60 sampled by the DC voltage detection circuit or AC voltage detection circuit configured on the power port 21. When the voltage is lower than a preset voltage threshold, it indicates that the remaining available power of the external power supply 60 is insufficient. Alternatively, the power distribution device 20 can directly communicate with the battery system (e.g., via CAN or RS485 bus) to obtain the remaining available power (SoC value) of the external power supply 60. Both the preset power threshold and the preset voltage threshold can be set according to actual needs.
[0059] As a specific example, the load control command could be an energy-saving mode trigger command. In this case, the control module can disable certain preset power distribution channel modules, preventing loads connected to these modules from consuming power. Users can configure which power distribution channel modules need to be disabled in energy-saving mode on the interactive device 10, providing greater user flexibility. For example, when the RV's battery system (the RV's domestic battery) has less than 20% remaining power, the system automatically triggers or the user manually triggers the energy-saving mode trigger command. In response to the received energy-saving mode trigger command, the power distribution device 20 automatically disconnects the circuits of power distribution channel modules connected to high-power appliances such as refrigerators, air conditioners, and induction cookers, ensuring that the remaining power supply meets the needs of necessary loads. Alternatively, as another optional implementation, the energy-saving mode trigger command is directly associated with the power distribution channel module connected to the 20A load. When the energy-saving mode is triggered, the power supply to the 20A load is automatically cut off, forcibly shutting off the power consumption of high-power loads.
[0060] The scene modes can also include at least one of an off-vehicle mode and an on-vehicle mode. The load control command can also be an off-vehicle mode trigger command. In this case, the control module can control the controlled switch in the power distribution channel module connected to the refrigerator to turn on, keeping the refrigerator in the open state and ensuring uninterrupted power supply. The load control command can also be an on-vehicle mode trigger command. In this case, the control module can control the controlled switch in the power distribution channel module connected to the ceiling light and bedroom light to turn on, forcibly turning on the ceiling light and bedroom light to maintain lighting inside the RV.
[0061] In this embodiment, the control module is configured to determine the corresponding power distribution control signal based on the scene mode trigger instruction, thereby adjusting the target working state of the load. This enables the power distribution system to centrally and uniformly control the working state of the load and correspond to a preset scene, such as an energy-saving mode scene. As a result, the working state of the load can be intelligently controlled according to the scene mode, thus improving the level of intelligence.
[0062] In an optional embodiment, the interactive device 10 is further configured to receive a scene mode configuration instruction, which is used to add a scene mode or configure a scene mode, each scene mode corresponding to the working state of at least one selected power distribution channel module 22 and the load connected to the power distribution channel module 22.
[0063] As a concrete example, users can formulate or modify load control strategies for each scene mode on the interactive device 10 (such as a touch screen), adjusting the working state of the load in each scene mode to achieve user-defined load control. For example, users can add at least one of a wake-up mode and a sleep mode. In the wake-up mode, at preset times, at least one of starting the rice cooker / coffee machine and turning on the bedroom light can be set. In this case, the control module controls the controlled switches in the power distribution channel module connected to the rice cooker and the bedroom light to turn on at the preset times.
[0064] In one alternative implementation, the load control command includes a timed switch control command, which is associated with at least one power distribution channel module 22; The control module 23 is configured to determine the corresponding power distribution control signal after a set delay period based on the timed switch control command, or the control module 23 is configured to determine the corresponding power distribution control signal based on the timed switch control command obtained after a set delay period, so that at least one power distribution channel module 22 adjusts the load connected to the preset power distribution channel module 22 to the target working state in response to the power distribution control signal.
[0065] As a concrete example, a user can set a timer for the power distribution channel module connected to the target load on the interactive device 10. The power distribution device 20 can then automatically switch on and off according to the set timer after receiving the switch control command. Alternatively, the local gateway or interactive device can periodically send switch control commands to the power distribution device 20 according to the set timer (the user can independently set the timed start or stop of the load), allowing the power distribution device 20 to respond immediately upon receiving the switch control command, thus achieving delayed control of the load's operating status. This function can meet the user's need to time the start or stop of specific loads, which is very helpful for RV living scenarios. For example, a user can set the timer to automatically turn on the coffee machine at 7:00 AM, so that the user can enjoy freshly made coffee after waking up.
[0066] In an alternative implementation, such as Figure 3 and Figure 4As shown, the power distribution channel module 22 also includes a power detection unit 223, which is configured to periodically detect the power parameters of the electrical energy supplied to the power distribution channel module 22. The power parameters include at least one of current, voltage, and power. The interactive device 10 is also configured to acquire and / or display power parameters.
[0067] As a specific example, the power detection unit 223 may include a current sensor (such as a coulomb meter). When the magnetic latching relay is turned on, the power detection unit 223 can collect load power parameters in real time (e.g., power accuracy can retain one decimal place, and voltage and current accuracy can be ±1%). Furthermore, since each power distribution channel module is equipped with a power detection unit, the load power parameters detected by the power detection unit can be displayed in real time through the interactive device 10, allowing users to easily view the energy consumption of each load. In RV living scenarios, the inconvenience of charging necessitates precise management of power usage. By displaying the current power parameters of each power distribution channel module and / or the power parameters within a preset time period in real time, users can accurately understand the current power consumption of each load in the RV and promptly shut down unnecessary loads to avoid energy waste.
[0068] In an optional embodiment, the control module 23 is further configured to determine a corresponding abnormal alarm signal based on the power parameters of the electrical energy supplied to the power distribution channel module 22, so that the interactive device 10 outputs a corresponding abnormal alarm prompt message in response to the abnormal alarm signal.
[0069] In an alternative embodiment, the control module 23 is further configured to perform at least one of the following operations: When the relationship between the power parameters and the preset power parameter thresholds meets the preset conditions, the corresponding abnormal alarm signal is determined. In response to the fact that the relationship between the power parameters and the preset power parameter thresholds meets the preset conditions and the working state of the load connected to the power distribution channel module meets the preset state, a corresponding abnormal alarm signal is determined. The corresponding abnormal alarm signal is determined based on the fact that the trend of the power parameter change curve over time conforms to the preset trend. When the duration for which the power parameter is greater than or equal to the preset power parameter threshold exceeds the preset duration, a corresponding abnormal alarm signal is determined.
[0070] In response to situations where the relationship between power parameters and preset power parameter thresholds meets preset conditions, a corresponding abnormal alarm signal is determined. In a specific example, this could be an overvoltage alarm signal triggered by a voltage greater than or equal to the maximum voltage threshold; an overcurrent alarm signal triggered by a current greater than or equal to the maximum current threshold; an undervoltage alarm signal triggered by a voltage less than or equal to the minimum voltage threshold; an undercurrent alarm signal triggered by a current less than or equal to the minimum current threshold; or an energy consumption alarm signal triggered by a power greater than or equal to the maximum power threshold. Therefore, the power distribution equipment 20 can automatically identify whether detected power parameters are abnormal and promptly issue an abnormal alarm signal when an abnormality occurs. The abnormal alarm signal can be issued through the interactive device 10 and / or the user terminal, allowing the user to promptly understand which load is experiencing an abnormal condition.
[0071] In a scenario where the relationship between power parameters and preset power parameter thresholds meets preset conditions, and the operating state of the load connected to the power distribution channel module meets preset conditions, in one specific example, when leakage current occurs in the circuit, even though the load is not running, the power detection unit can still detect the presence of current in the circuit. Therefore, an abnormal alarm signal should be issued to alert the user that an abnormality has occurred in the power distribution circuit. For another example, even though the power distribution channel module is in a conducting state, if the power detection unit does not detect current or power consumption in the circuit, it may indicate an abnormality in the load (the magnetic latching relay is open, but the load is not operating). Therefore, an abnormal alarm signal should be issued to alert the user that an abnormality has occurred in the power distribution circuit.
[0072] In a specific example, to address situations where the trend of power parameter changes over time conforms to a preset trend, the power distribution equipment 20 periodically stores the detected power parameters in its local memory. This establishes a power parameter-time curve, allowing the user to understand the operating status of the load over a period of time. Furthermore, when the load's operating status changes, the corresponding power parameter-time curve also changes. Therefore, the load's operating status can be determined based on the curve's trend characteristics. For example, if the refrigerator door is open, the refrigerator's current curve will remain at a high power level for an extended period; if the refrigerator door is closed, the current curve will fluctuate. Therefore, based on the current curve, it is possible to analyze whether there is an anomaly in the load and issue a corresponding anomaly alarm.
[0073] In response to situations where the duration for which power parameters are greater than or equal to a preset power parameter threshold exceeds a preset time, in one specific example, the power detection unit 223 of the power distribution equipment 20 periodically stores the detected power parameters in its local memory. When a power parameter is detected to be greater than or equal to the preset power parameter threshold, it is considered that the load is in operation. If the duration for which the detected power parameter is greater than or equal to the preset power parameter threshold exceeds the load's usual usage time (i.e., the preset time, which can be customized on the interactive device as needed), it indicates that the user may have forgotten to turn off the load. For example, a washing machine or microwave oven in a vehicle may be using electricity for an extended period, or the load may have been left on for a long time without being turned off in time, wasting electricity. Therefore, a corresponding abnormal alarm signal can be determined to remind the user to check the load in the corresponding power distribution channel and turn it off in time to avoid wasting limited electrical energy.
[0074] In this embodiment of the application, the power distribution equipment 20 is also configured with an abnormal alarm function. By configuring an abnormal monitoring and alarm strategy, after the control module of the power distribution equipment 20 determines that an abnormal event has occurred, the interactive device 10 or the user terminal outputs an abnormal alarm prompt message based on the abnormal alarm signal, so as to promptly remind the user of possible abnormal events, thereby improving the intelligence level and safety management of the entire power system.
[0075] In an alternative implementation, the control module 23 is further configured to determine the remaining power of the external power supply 60, and to determine the available duration based on the power parameters and the remaining power. Interactive device 10 is also configured to acquire and / or display available time.
[0076] For users, the remaining battery power information in the RV's battery system is crucial, allowing them to replenish power promptly when it's low. However, in certain scenarios, users may be more concerned with how long the remaining battery power can support their current usage, helping them determine if it meets their current electricity needs. Therefore, as a specific example, the control module can acquire the real-time power consumption of each channel and, based on the remaining available power of the external power source 60, determine the usable duration under the current power consumption, then inform the user through the interactive device 10 and / or the user terminal. Here, the external power source 60 can be a battery, and the determination of the usable duration includes the following two scenarios: If the battery in the energy system has no charging source, then the available time = remaining power (kWh) / current power consumption of all loads (kW).
[0077] If the battery in the energy system has a charging source (e.g., the possibility of solar panels or vehicle engine charging the battery), then the available time = remaining power (kWh) / (current power consumption of all loads (kW) - current battery charging power (kW)); where the current battery charging power can be obtained by the local gateway from the charger.
[0078] As a specific example, when the remaining battery power falls below a certain threshold, the system can automatically or allow the user to choose whether to switch to a low-energy mode. In low-energy mode, only necessary loads can be used, while unnecessary loads can be disabled. The definition of whether each load is necessary can be customized by the user through the interactive device 10, and the local gateway will store the configuration. For example, necessary loads may include at least one of ceiling lights, bedside lamps, water heating, and electric steps, while unnecessary loads may include at least one of awning lights, ambient lights, drain valves, fan heaters, and exhaust fans. After enabling low-energy mode, the controlled switch in the power distribution channel module connected to the unnecessary load is disconnected, and the operation interface button on the interactive device 10 corresponding to the unnecessary load is disabled. The controlled switch in the power distribution channel module connected to the necessary load can still be turned on under the control of the control module to maintain the user's necessary power needs, thereby realizing low-energy mode.
[0079] In an alternative implementation, such as Figure 7 As shown, the power distribution equipment 20 also includes: Several digital signal input ports 24 are configured to acquire operating signals of vehicle components 70, including at least one of vehicle ignition signal, door opening / closing signal and brake signal. Several digital signal output ports 25, each digital signal output port 25 is connected to the vehicle-mounted equipment drive mechanism 80; The control module 23 is also configured to determine the corresponding drive mechanism control signal based on the operating signal of the vehicle component 70, so that the digital signal output port 25 adjusts the on-board equipment drive mechanism 80 connected to the digital signal output port 25 to the target operating state in response to the drive mechanism control signal.
[0080] As a specific example, the power distribution device 20 is further provided with a digital signal input port 24, which can be connected to the OBD interface of the vehicle to read the ignition and brake signals of the vehicle through the CAN bus. In addition, a user can also install a door magnetic sensor at the door of the living compartment of the recreational vehicle to detect and output an opening / closing signal of the door and send the signal to the power distribution device 20. Based on the acquired working signal of the vehicle component 70, the power distribution device 20 can execute some linkage control strategies. For example, when the digital signal input port 24 receives an ignition signal of the vehicle, it indicates that the user may need to drive the vehicle, so the control module 23 outputs a driving mechanism control signal through the digital signal output port 25 to control, for example, an awning, an electric step, and electric support legs to be automatically retracted, so as to realize automatic control of the vehicle-mounted equipment driving mechanism 80. For another example, when a door opening signal is received, the control module 23 outputs a driving mechanism control signal through the digital signal output port 25 to control the electric step at the door to automatically extend down, so that the user can step on the step to get off the vehicle when opening the door. For still another example, when an engine rotation speed signal is received, if it is confirmed that the rotation speed of the engine exceeds a set threshold, it indicates that the vehicle may be in a driving state, and the power distribution device 20 can lock the control signals for the driving mechanisms of the awning, the electric step and the electric support legs, so that the awning, the electric step and the electric support legs cannot be opened while the vehicle is driving, thereby ensuring driving safety; in addition, the power distribution device 20 is further configured to send a signal to the interaction device 10, so that the operation buttons corresponding to the awning, the electric step and the electric support legs in the interaction device 10 are disabled, so as to prevent safety hazards caused by accidental triggering of such devices during driving. Certainly, an operation button for implementing "one-touch unfolding" is further disposed on the interaction device 10. After the vehicle is parked at a campsite, the user can trigger the operation button to send an unfolding signal. After receiving the unfolding signal, the power distribution device 20 outputs a control signal to unfold the awning, the electric step and / or the electric support legs, so as to realize parking and camping.
[0081] In an optional embodiment, the control module 23 further includes a memory, which is configured to store the working state of each power distribution channel module 22, where the working state includes a default working state and a real-time working state; The control module 23 is further configured to, in response to the power distribution device 20 being powered on again, determine a corresponding power distribution control signal according to the working state stored in the memory, so that the power distribution channel module 22 adjusts the working state of the power distribution channel module 22 to the default working state or the real-time working state in response to the power distribution control signal.
[0082] As a specific example, if the control module adjusts the operating state of the power distribution channel module to the real-time operating state, it means that upon power restoration, the previous operating state will be directly restored. This allows the power distribution system to support the memory and saving of power outage states, ensuring that the load's operating state before the power outage can be directly restored upon the next power restoration. If the control module adjusts the operating state of the power distribution channel module to the default operating state, it means that the load will remain in the default operating state after power restoration, preventing the load from being accidentally started after a power outage. Users can configure the operating state of each power distribution channel module after a power outage on the interactive device 10 or the user terminal, selecting either the default or real-time operating state depending on the nature of the load. For power distribution channel modules that have not been configured by the user, the initial setting is the default operating state.
[0083] In an alternative implementation, such as Figure 7 As shown, the power distribution equipment 20 also includes: Several analog signal input ports 26 are configured to acquire the detection signals of the liquid level sensor 90; The control module 23 is also configured to determine the corresponding power distribution control signal based on the detection signal of the liquid level sensor 90, so that the power distribution channel module adjusts the load connected to the power distribution channel module to the target operating state in response to the power distribution control signal. Alternatively, the control module may be configured to determine a corresponding abnormal alarm signal based on the detection signal from the level sensor, so that the interactive device responds to the abnormal alarm signal by outputting a corresponding abnormal alarm message.
[0084] As a specific example, the level sensor 90 detects the water level in the water tank in real time and sends the detected water level information to the power distribution equipment. If the level sensor 90 of the clean water tank detects that the water level is 0 or lower than the set value, the power distribution channel module 22 where the water pump 53 is located can no longer be turned on, and the control module 23 determines the power distribution control signal to shut down the water pump. In addition, if the level sensor detects that the water level in the clean water tank is lower than a certain threshold, or the water level in the black water tank or grey water tank is higher than a certain threshold, an abnormal alarm signal will be generated and sent to the interactive device 10 and / or the user terminal, causing the interactive device 10 and / or the user terminal to output an abnormal alarm message to remind the user to replenish or drain the water tank in time. Optionally, the power distribution equipment 20 is also connected to a temperature sensor 91 to obtain the temperature information inside and outside the RV, and a load linkage control strategy can also be configured based on this temperature information. For example, when the temperature is higher than the set value, the power distribution equipment 10 automatically starts the power distribution channel module connected to the air conditioner or fan to realize the temperature regulation inside the RV.
[0085] This application also provides a control method for a power distribution system, such as... Figure 1As shown, the power distribution system 100 includes an interaction device 10 and a power distribution device 20. The interaction device 10 is adapted to connect to the power distribution device 20 via a first communication link. The power distribution device 20 includes a plurality of power distribution channel modules 22. Each power distribution channel module 22 is configured to selectively supply input power to at least one load 50 connected to that power distribution channel module 22 according to a power distribution control signal. Figure 7 As shown, the method includes: Step S10: Receive user operation instructions for implementing load control; Step S20: Output the load control command corresponding to the user operation command; Step S30: Determine the corresponding power distribution control signal according to the load control command, so that the power distribution channel module 22 responds to the power distribution control signal to adjust the load 50 connected to the power distribution channel module 22 to the target working state.
[0086] As a specific example, in step S10, the interactive device receives a user operation command for implementing load control. In step S20, the interactive device generates and outputs a load control command corresponding to the received user operation command. In step S30, the power distribution equipment 20 further includes a control module 23. The control module 23 receives the load control command, determines the corresponding power distribution control signal based on the load control command, and outputs it to the power distribution channel module 22. The power distribution channel module 22 adjusts the load connected to it to the target operating state in response to the power distribution control signal. The specific steps of the power distribution channel module 22 adjusting the load connected to it to the target operating state in response to the power distribution control signal can be found in the descriptions of lamp loads and water pumps in the above embodiments, and will not be repeated here.
[0087] In this embodiment, the user operation command can be input directly by the user on the interactive device (such as a touch screen), or it can be input by the user through a user terminal (such as a mobile phone, tablet computer, or smartwatch) and obtained through the second communication link. The interactive device receives the user operation command for load control and outputs the corresponding load control command. The control module determines the corresponding power distribution control signal based on the load control command, so that the power distribution channel module responds to the power distribution control signal and adjusts the load connected to the power distribution channel module to the target operating state. This enables the power distribution system, including the interactive device and the power distribution equipment, to achieve centralized and unified control of the target operating state of each load, realizing systematic intelligent control of all electrical equipment and improving the intelligence level of the energy system.
