[0032] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0033] First, the application scenarios of this disclosure are introduced. This application is applied in the scenario of power distribution control of vehicle equipment, wherein the vehicle may be equipped with optical communication. With the continuous development of vehicle technology, the demand for communication bandwidth, real-time performance, and reliability is constantly increasing. In order to meet the development needs of vehicle communication, optical communication is applied to vehicle communication networks.
[0034] Among related technologies, optical communication, a mature technology characterized by high bandwidth, high reliability, low latency, and low cost, can be introduced into vehicle communication as the backbone network. Devices using different protocols and dedicated lines, such as cameras, displays, and radars, can be unified using the optical communication network. This, combined with mature regional CANFD and Ethernet networks, forms a novel heterogeneous network architecture to meet the communication needs of vehicles. Applying optical communication to vehicle communication networks can significantly alleviate the problem of limited bandwidth within vehicles and reserve bandwidth space for future functional upgrades and expansions. However, while optical communication, as a mainstream and mature communication technology, does not have high power consumption requirements in scenarios such as data centers and broadband internet transmission, its application in vehicle communication networks necessitates strict power consumption control.
[0035] Optical communication can improve the communication efficiency of vehicular communication networks. However, optical communication equipment consumes a lot of power during operation, which leads to high power consumption in vehicles when using optical communication through vehicular communication networks.
[0036] To address the aforementioned problems, this disclosure provides a power distribution control system and a vehicle. The system includes: multiple optical terminal devices, a power distribution device, and an optical communication control and monitoring device. The power distribution device is electrically connected to both the multiple optical terminal devices and the optical communication control and monitoring device. The multiple optical terminal devices and the optical communication control and monitoring device are connected via a first optical distribution network. The optical communication control and monitoring device is used to control the power distribution device to distribute or disconnect power to at least one device based on at least one of the communication needs, network management status, and device status information of the multiple optical terminal devices. The at least one device includes at least one of the multiple optical terminal devices, the power distribution device, and the optical communication control and monitoring device. Through this technical solution, power can be distributed or disconnected to at least one device in the vehicle via the power distribution device based on at least one of the communication needs, network management status, and device status information of the optical terminal devices. This achieves highly efficient management of the power consumption of multiple devices in the vehicle, meeting the vehicle's requirements for low power consumption and high timeliness.
[0037] Figure 1 This is a block diagram illustrating a power distribution control system according to an exemplary embodiment. For example... Figure 1 As shown, the system may include: multiple optical terminal devices 110, a power distribution device 120, and an optical communication control and monitoring device 130; the power distribution device 120 is electrically connected to the multiple optical terminal devices 110 and the optical communication control and monitoring device 130 respectively; the multiple optical terminal devices 110 and the optical communication control and monitoring device 130 are connected through a first optical distribution network 140. The optical communication control and monitoring device 130 is used to control the power distribution device 120 to distribute or cut off power to at least one device based on at least one of the communication needs, network management status, and device status information of the plurality of optical terminal devices 110. The at least one device includes at least one of the plurality of optical terminal devices, the power distribution device, and the optical communication control and monitoring device.
[0038] For example, the optical communication control and monitoring device 130 can control the power distribution device 120 to distribute power to the plurality of optical terminal devices, the power distribution device, and the optical communication control and monitoring device; or, it can control the power distribution device to cut off power to the plurality of optical terminal devices, the power distribution device, and the optical communication control and monitoring device.
[0039] For example, the optical communication control and monitoring device 130 can power some of the multiple devices and power off the others. For instance, the optical communication control and monitoring device can power off the multiple optical terminal devices and power the power distribution device; or, the optical communication control and monitoring device can power both the multiple optical terminal devices and the power distribution device, without limitation.
[0040] In the technical solutions provided in this disclosure, the optical terminal device can be understood as a functional device in a vehicle that integrates an ONU (Optical Network Unit), such as at least one or more functional devices selected from the following: body controller, brake controller, power controller, intelligent driving controller, radar, camera, and screen. Alternatively, the optical network unit and the functional device can be set separately in the vehicle. In this case, the optical terminal device in the technical solutions provided in this disclosure can also be understood as the optical network unit. For example, a corresponding optical network unit can be set for each device in the vehicle that has signal interaction requirements.
[0041] Furthermore, the optical communication between the optical communication control and monitoring device and multiple optical terminal devices can employ XGS-PON (10-Gigabit-capable symmetric Passive Optical Network). XGS-PON is a passive optical access technology using a point-to-multipoint topology, consisting of an OLT (Optical Line Terminal) on the central office side, an ONU (Optical Network Unit) on the user side, and an ODN (Optical Distribution Network). That is, in the technical solution provided in this disclosure, the optical communication control and monitoring device may include an OLT communication module, and the optical terminal device is used to establish an optical communication connection with the OLT communication module under power distribution conditions. Figure 1 As shown, the optical communication control and monitoring device 130 may include an OLT (Optical Line Terminal) communication module 1201. The OLT communication module 1201 can be connected to a splitter via optical fiber, and the splitter connects to multiple optical terminal devices 110, thereby forming a first optical distribution network 140 for transmitting optical signals between the multiple optical terminal devices 110 and the OLT communication module 1201.
[0042] The following example illustrates how the optical communication control and monitoring device 130 can control the power distribution device 120 to power or de-power at least one device based on communication needs. For instance, the optical terminal device may include a camera and an ONU connected to the camera. When the device detects that a user has activated the camera, it determines that the camera has communication needs, and thus the optical communication control and monitoring device 130 can control the power distribution device 120 to power the optical terminal device.
[0043] The following example illustrates how the optical communication control and monitoring device 130 can control the power distribution device 120 to distribute or cut off power to at least one device based on the network management status.
[0044] For example, the network management state can include a sleep state and a switch to sleep state. The optical communication control and monitoring device can control the power distribution device to cut off power to one or more devices when their network management state is either sleep or switched to sleep. Since the device is in sleep mode, it can be confirmed that the device does not need to operate; cutting off power reduces power consumption and achieves power control. The switch to sleep state can refer to the device transitioning from a wake-up state to a sleep state.
[0045] For example, the network management state can include a wake-up state and a switch to wake-up state. The optical communication control and monitoring device can control the power distribution device to distribute power to the multiple optical terminal devices, the power distribution device, and the optical communication control and monitoring device when the network management state is in a wake-up state or a switch to wake-up state. Here, the switch to wake-up state can refer to the process of a device switching from a sleep state to a wake-up state.
[0046] For example, the aforementioned wake-up state may include a network-wide wake-up state and at least one local area network (LAN) wake-up state, wherein the at least one LAN wake-up state may include a first LAN wake-up state; when the network management state is the network-wide wake-up state or has switched to the network-wide wake-up state, the optical communication control and monitoring device controls the power distribution device to distribute power to the multiple optical terminal devices, the power distribution device, and the optical communication control and monitoring device; when the network management state is the first LAN wake-up state or has switched to the first LAN wake-up state, the optical communication control and monitoring device controls the power distribution device to distribute power to the devices corresponding to the first LAN wake-up state.
[0047] The "wake-up state of the whole network" can refer to all devices in the vehicle being in a wake-up state; the "wake-up state of the local area network" can refer to some devices in the vehicle being in a wake-up state.
[0048] The device corresponding to the first local area network wake-up state may include at least one optical terminal device, the power distribution device, the optical communication control and monitoring device, and the screen of the optical terminal device; or, the device corresponding to the first local area network wake-up state may include the power distribution device, the optical communication control and monitoring device, and the screen of the optical terminal device.
[0049] The optical communication control and monitoring device can, when the network management state is in the first LAN wake-up state, control the power distribution device to distribute power to at least one optical terminal device, the power distribution device, the optical communication control and monitoring device, and the screen of the optical terminal device; or, when the network management state is in the first LAN wake-up state, the optical communication control and monitoring device can control the power distribution device to distribute power to the power distribution device, the optical communication control and monitoring device, and the screen of the optical terminal device. In this way, power can be distributed to the corresponding devices according to the network management state, thereby achieving power consumption management of multiple devices.
[0050] The network management status of a vehicle can be managed by a network management state machine. Figure 2 Taking the diagram illustrating the relationship between network management states as an example, from... Figure 2 It can be seen that the network management state can include at least the sleep state, the whole network wake-up (or full network wake-up) state, the first local area network wake-up state, and the second local area network wake-up state; and the network management states can be switched between each other.
[0051] The first LAN wake-up state can be achieved by the LAN state machine controlling the power distribution device, optical communication control and monitoring device, and optical terminal equipment screen; the second LAN wake-up state can be achieved by the LAN state machine controlling the power distribution device, optical communication control and monitoring device, and optical terminal equipment camera. Each state machine can switch according to the jump conditions defined by the functional requirements.
[0052] In the technical solution provided by the embodiments of this disclosure, the optical communication control and monitoring device can always be in a power distribution state, thereby enabling timely control of other devices.
[0053] The optical communication control and monitoring device controls the power distribution device to distribute or disconnect power to at least one device by sending power distribution control commands to the power distribution device. For example, the power distribution control command can be an electrical signal. The power distribution control command can be transmitted via a CAN bus.
[0054] For example, the power distribution control command may include a power distribution command. The optical communication control and monitoring device may be used to send the power distribution command to the power distribution device when the network management state is in the network wake-up state or switched to the network wake-up state, so as to control the power distribution device to distribute power to at least one device.
[0055] For example, the power distribution control command may include a power-off command. The optical communication control and monitoring device can be used to send the power-off command to the power distribution device when the target device switches from the wake-up state to the sleep state, so as to control the power distribution device to cut off power to at least one device. In this way, the power distribution device can be controlled by the power distribution command and the power-off command respectively to realize the power distribution and power-off of the corresponding devices.
[0056] The aforementioned at least one device may include a first optical terminal device. When the power distribution device supplies power to the first optical terminal device, and the optical communication control and monitoring device detects a communication abnormality in the first optical terminal device, the optical communication control and monitoring device determines whether the first optical terminal device has a power supply failure or a communication failure based on the power supply feedback signal fed back by the power distribution device.
[0057] For example, the first optical terminal device can be a device with signal interaction requirements.
[0058] For example, the power supply feedback signal may include at least one of the power supply port status of the first optical terminal device and the power supply current of the first optical terminal device. This allows the fault type of the optical terminal device to be determined based on the power supply feedback signal in the event of a communication failure.
[0059] The optical communication control and monitoring device can determine that the first optical terminal device has a power supply failure when it detects both communication abnormalities and abnormal power supply feedback signals. Alternatively, the device can determine the fault type of the first optical terminal device by combining the communication status of other optical terminal devices in the vehicle, provided that the first optical terminal device has a communication abnormality and the power supply feedback signal is normal. These other optical terminal devices are those other than the first optical terminal device among the multiple optical terminal devices in the vehicle.
[0060] This optical communication control and monitoring device can determine that the first optical terminal device is experiencing a communication failure when the communication of other optical terminal devices is normal. Since the power supply feedback signal of the first optical terminal device is normal under these circumstances, and other optical terminal devices can communicate normally, it can be determined that the fault type of the first optical terminal device is a communication failure.
[0061] The optical communication control and monitoring device detects whether the first optical terminal device is experiencing communication abnormalities by monitoring burst data frames of the first optical terminal device.
[0062] If the optical communication control and monitoring device fails to receive burst data frames from the first optical terminal device more than a first threshold number of times, it confirms that the first terminal device is in communication abnormality. For example, the first threshold can be in the range of 2-8 times, such as 2, 3, 4, 6 or 8 times, etc., and is not limited here.
[0063] The optical communication control and monitoring device can also be configured to, in the event of a communication failure in the first optical terminal device, determine whether all of the multiple optical terminal devices have communication failures. If all of the multiple optical terminal devices have communication failures, the optical communication control and monitoring device switches to communicating with the multiple optical terminal devices through a second optical distribution network. Specifically, before determining whether all of the multiple optical terminal devices have communication failures, the optical communication control and monitoring device can first determine whether the first optical terminal device is a device with signal interaction requirements. That is, if the first optical terminal device is a device with signal interaction requirements, then the device determines whether all of the multiple optical terminal devices have communication failures; if the first optical terminal device is not a device with signal interaction requirements, then no further determination is needed.
[0064] If the first optical terminal device experiences a communication failure, possible causes include a communication function failure within the first optical terminal device itself (e.g., device damage) or a transmission failure of the optical signal in the first optical distribution network. In the above embodiment, if it is determined that not all optical terminal devices are experiencing communication failures, the communication function failure of the first optical terminal device itself can be further identified. If all optical terminal devices are experiencing communication failures, the optical communication control and monitoring device switches to communicating with the multiple optical terminal devices through the second optical distribution network. In this case, the cause of the failure can be further identified by assessing the communication recovery status of the multiple optical terminal devices.
[0065] For example, if communication of multiple optical terminal devices returns to normal after switching to the second optical distribution network, it can be determined that the communication failure of the first optical terminal device was caused by a transmission failure in the first optical distribution network. If multiple optical terminal devices still experience communication failures, it can be determined that both the first and second optical distribution networks have transmission failures, or that multiple optical terminal devices have communication function failures. If other first optical terminal devices have resumed normal communication, but the aforementioned first optical terminal device with a communication failure still experiences a failure, it can be ultimately determined that the first optical terminal device itself has a communication function failure.
[0066] Furthermore, after switching to the second optical distribution network, if the multiple optical terminal devices resume normal communication, the optical communication control and monitoring device switches to communicate with the multiple optical terminal devices through the first optical distribution network. Specifically, after the communication fault is resolved, the optical communication control and monitoring device switches to communicate with the multiple optical terminal devices through the first optical distribution network.
[0067] Figure 3 This is a block diagram illustrating an exemplary embodiment of an optical communication control and monitoring device. For example... Figure 3 As shown, the optical communication control and monitoring device may include a CAN communication module, an OLT communication module, a power distribution control module, a network management module, a data processing module, and a fault analysis module. The CAN communication module can communicate with the power distribution device and other modules via the CAN bus; the OLT communication module can communicate with various optical terminal devices via optical fiber and monitor optical communication faults in the optical terminal devices.
[0068] The power supply for multiple optical terminal devices is controlled by the power distribution control module. This network management module responds to the network management status of the entire vehicle. Based on inputs from the network management module and functional requirements, the power distribution control module sends power distribution control commands to the power distribution devices and receives power distribution status feedback from the devices. The fault analysis module performs fault diagnosis based on network management status, power distribution status, device status information, and optical communication status information.
[0069] The above technical solution enables the distribution or de-energization of power to at least one device in a vehicle based on at least one of the communication requirements, network management status, and device status information of the optical terminal equipment. This allows for efficient management of the power consumption of multiple devices in the vehicle, meeting the vehicle's requirements for low power consumption and high timeliness.
[0070] In some embodiments, the network management module of the optical communication control and monitoring device can generate a power distribution control command based on at least one of the communication requirements of the optical terminal device, the network management status, and the device status information, and send the power distribution control command to the power distribution control module; the power distribution control module can send the power distribution control command to the power distribution device through the CAN communication module; the power distribution device can distribute power to or disconnect power to the corresponding device according to the power distribution control command, thereby establishing or disconnecting optical communication between the device and the optical communication control and monitoring device.
[0071] In other embodiments, the network management module of the optical communication control and monitoring device can set its own network status according to its own functional requirements or in response to the network management status request of the vehicle ECU, and send network management messages through the CAN network. The power distribution control module of the optical communication control and monitoring device sends power distribution control command messages according to the power distribution requirements of the optical terminal equipment corresponding to the network management status of the network management module.
[0072] The OLT communication module can establish faults of each optical terminal device through the XGS-PON fault detection mechanism, including burst data and signal loss of optical terminal devices, interference warning transmission of optical terminal devices, and failure to start up optical terminal devices. The optical communication module transmits the detected fault information to the fault analysis module, which performs unified analysis and processing.
[0073] The above technical solution enables the distribution or de-energization of power to at least one device in a vehicle based on at least one of the communication requirements, network management status, and device status information of the optical terminal equipment. This allows for efficient management of the power consumption of multiple devices in the vehicle, meeting the vehicle's requirements for low power consumption and high timeliness.
[0074] The following example illustrates the workflow of the optical communication control and monitoring device in the power distribution control system, which controls the power distribution device to distribute or cut off power to at least one device based on network management status. Figure 4 As shown, the workflow may include the following steps.
[0075] S401, the optical communication control and monitoring device determines the network management status of multiple optical terminal devices.
[0076] The network management state includes a sleep state and / or switching to a sleep state, and also includes a wake-up state and / or switching to a wake-up state.
[0077] S402. When the network management state is in a wake-up state or has been switched to a wake-up state, the optical communication control and monitoring device determines the state type of the wake-up state.

[0082] The device corresponding to the first local area network wake-up state may include at least one optical terminal device, the power distribution device, the optical communication control and monitoring device, and the screen of the optical terminal device; or, the device corresponding to the first local area network wake-up state may include the power distribution device, the optical communication control and monitoring device, and the screen of the optical terminal device.
[0083] S405. The optical communication control and monitoring device determines whether the network management status of the multiple optical terminal devices is in a dormant state and / or switched to a dormant state.
[0084] If it is determined that the network management state is in a dormant state and / or has switched to a dormant state, execute S406; If it is determined that the network management state is not in a dormant state and / or has switched to a dormant state, return to S401.
[0085] S406, The optical communication control and monitoring device controls the power distribution device to cut off power to the multiple optical terminal devices, the power distribution device, and the optical communication control and monitoring device.
[0086] The above technical solution enables the distribution or de-energization of power to at least one device in a vehicle based on at least one of the communication requirements, network management status, and device status information of the optical terminal equipment. This allows for efficient management of the power consumption of multiple devices in the vehicle, meeting the vehicle's requirements for low power consumption and high timeliness.
[0087] The following example illustrates the workflow of the optical communication control and monitoring device in performing fault analysis on the first optical terminal device in the power distribution control system, where the power distribution device is at least one of the devices. Figure 5 As shown, the workflow may include the following steps.
[0088] S501, the optical communication control and monitoring device controls the power distribution device to distribute power to the first optical terminal device among multiple optical terminal devices.
