Description

[0002] The low-voltage electrical switches of unmanned vehicles generally use multi-channel relays or MOS to control multiple loads and supply power to the loads. These technologies have some shortcomings, such as:

[0003] (1) Most of the above are open-loop controls without a complete closed-loop feedback system. If a short circuit or open circuit occurs, the vehicle control system cannot sense in real time whether the load status of each line is abnormal, which may cause danger.

[0004] (2) The above control method uses oscilloscopes, multimeters and other test instruments during vehicle power consumption testing. This may result in inaccurate testing during static testing. In addition, in some test conditions, such as when the vehicle is driving, it is not possible to use the above instruments to record the power consumption of each module.

[0005] (3) At the same time, the relay has a slow response speed, and there are also process differences, which lead to different action times. For modules with strict power-on timing requirements, this will also have an impact. Relays are large in size, have large leakage currents, are expensive, and will wear out after working for a long time, resulting in poor contact of the contacts.

[0006] (4) If the upper-level module IO is used for control, there are too many wiring harnesses in the vehicle, and unknown interference may be coupled in, causing malfunctions and dangerous situations.

[0040] See also Figure 1 , Figure 1 This is a schematic diagram provided by the embodiment of the present application, which will be combined with Figure 1 Provide explanation.

[0041] A feedback system, a target power source 2 supplies power to a plurality of loads 5 through at least one power supply circuit, each load 5 corresponds to a power supply circuit, and the feedback system comprises: at least one electronic switch 3, a signal collection module and a control module 4;

[0042] The number of the at least one electronic switch 3 matches the number of the at least one power supply circuit, and each of the at least one electronic switch 3 controls the on / off of a power supply circuit;

[0043] The signal collection end of the signal collection module is respectively connected to the signal feedback end of each of the multiple loads 5, the control end of the control module 4 is respectively connected to the signal input end of the at least one electronic switch 3, and the signal output end of the signal collection module is connected to the signal input end of the control module 4;

[0044] When working, the signal collection module collects the status information of each load 5 in real time, and transmits the status information to the control module 4. The control module 4 controls the opening and closing of the at least one electronic switch 3 based on the status information.

[0045] The feedback system is designed to achieve accurate power supply management and status monitoring of multiple loads 5 in unmanned vehicles or other equipment. The feedback system can be composed of:

[0046] Target power supply 2: Provides electrical energy and is the source of the power supply system.

[0047] Power supply circuit: a circuit channel connecting the target power supply 2 and the load 5. Each load 5 has a corresponding power supply circuit.

[0048] Electronic switch 3: used to control the on and off of the power supply circuit to achieve power supply management for the load 5. Each electronic switch 3 controls a power supply circuit to ensure independent control of each circuit.

[0049] Signal collection module: responsible for collecting the status information of each load 5 in real time. Such status information may include the current, voltage, temperature, working status, etc. of the load 5. The signal collection end of the signal collection module is connected to the signal feedback end of each load 5 to ensure that the real-time status of the load 5 can be obtained in real time.

[0050] Control module 4: As the core of the system, it receives the status information transmitted by the signal collection module and judges whether the working status of the load 5 is normal based on the information. Based on the judgment result, the control module 4 sends instructions to the electronic switch 3 to control its opening and closing, thereby realizing precise control of the power supply to the load 5.

[0051] During operation, the signal collection module continuously collects the status information of each load 5 in real time, and after processing, the information is transmitted to the control module 4 through the signal output terminal. After receiving the information, the control module 4 analyzes and judges. If it is found that the status of a load 5 is abnormal (such as current overload, voltage too high or too low, etc.), the control module 4 will immediately send a command to the corresponding electronic switch 3 to cut off the power supply circuit of the load 5 to prevent the fault from expanding.

[0052] At the same time, the control module 4 can also intelligently adjust the on / off state of the power supply circuit according to the working state of the load 5 to achieve efficient use of energy. For example, when the load 5 is in an idle state or a low power consumption mode, the control module 4 can cut off or reduce its power supply through the electronic switch 3 to save energy.

[0053] The advantage of this feedback system is that it can achieve precise control of the power supply circuit and real-time monitoring of the load 5 status. This not only improves the safety and stability of the power supply system, but also optimizes energy utilization, reduces equipment failure rate, and extends the service life of the equipment. In addition, the feedback system is also highly scalable and can adapt to power supply systems of different sizes and needs.

[0054] The feedback system provided in the embodiment of the present application can provide an effective solution for power management of unmanned vehicles or other equipment, thereby improving the overall performance and reliability of the equipment.

[0055] In some embodiments, the signal collection module includes a current collection module 6 and a voltage collection module 7, the signal feedback end of each load 5 in the plurality of loads 5 includes a current feedback end and a voltage feedback end, and the state information includes a current state and a voltage state;

[0056] The signal acquisition end of the current acquisition module 6 is respectively connected to the current feedback end of each load 5 in the multiple loads 5; the signal acquisition end of the voltage acquisition module 7 is respectively connected to the voltage feedback end of each load 5 in the multiple loads 5;

[0057] When working, the current acquisition module 6 acquires the current state and the voltage state of each load 5 in real time.

[0058] Here, the signal collection module in the feedback system is designed to include a current acquisition module 6 and a voltage acquisition module 7. These two modules are respectively responsible for collecting the current and voltage status information of the load 5, so as to fully understand the working status of the load 5 and provide a rich data basis for the control module 4, so as to more accurately control the opening and closing of the electronic switch 3.

[0059] Next, the current acquisition module 6 and the voltage acquisition module 7 will be explained respectively:

[0060] Current acquisition module 6: signal acquisition terminal: connected to the current feedback terminal of each load 5, responsible for real-time acquisition of current status information of the load 5.

[0061] Function: By monitoring the current size, fluctuation and other information, it can be determined whether the load 5 is in a normal working state, and whether there are abnormal conditions such as overload and short circuit.

[0062] Voltage acquisition module 7: signal acquisition terminal: connected to the voltage feedback terminal of each load 5, responsible for real-time acquisition of voltage status information of the load 5.

[0063] Function: By monitoring the stability and change of voltage, it can be determined whether the load 5 is supplied with stable power, and whether there are problems such as undervoltage and overvoltage.

[0064] Each load 5 is designed with a current feedback terminal and a voltage feedback terminal, and these two ports are respectively connected to the current acquisition module 6 and the voltage acquisition module 7 to ensure that the signal collection module can accurately obtain the current and voltage status information of the load 5.

[0065] When working, the current acquisition module 6 and the voltage acquisition module 7 will work simultaneously to collect the current state and voltage state of each load 5 in real time. After being processed, this information will be transmitted to the control module 4. Based on this state information, the control module 4 can comprehensively judge the working state of the load 5 and control the opening and closing of the electronic switch 3 as needed. In this way, the current and voltage state information can be collected simultaneously, and the working state of the load 5 can be understood more comprehensively. Based on the rich state information, the control module 4 can more accurately judge the working state of the load 5 and control the opening and closing of the electronic switch 3. Real-time monitoring of the current and voltage state can timely discover potential fault risks and prevent the occurrence of faults.

[0066] The above method provides strong data support for the feedback system, enabling the system to more accurately control the power supply circuit and improve the safety and stability of the power supply system.

[0067] In some embodiments, the control module 4 is a microcontroller, which is used to judge the status information of each load 5, and when the judgment result is abnormal, control the corresponding electronic switch 3 to disconnect to disconnect the power supply circuit where the abnormal load 5 is located.

[0068] In the feedback system, the control module 4 is responsible for making decisions based on the state information of the load 5 and controlling the opening and closing of the electronic switch 3. In this solution, the control module 4 is embodied as a microcontroller, which can be a small computer chip, usually used to control and monitor electronic equipment.

[0069] The main task of the microcontroller in the feedback system is to receive the load 5 status information from the signal collection module, including the current status and voltage status, etc. These status information reflect the working conditions of the load 5, such as whether it is overloaded, undervoltage or overvoltage, etc. The microcontroller has a built-in processing program that can analyze and judge these status information.

[0070] When the microcontroller determines that the status information of a load 5 is abnormal, such as the current exceeds the normal range or the voltage is unstable, it will respond quickly. The microcontroller sends a disconnection instruction to the corresponding electronic switch 3 through the control signal output terminal. After receiving the instruction, the electronic switch 3 will immediately disconnect the power supply circuit connected to the load 5, thereby cutting off the power supply of the abnormal load 5. This effectively protects the load 5 and the entire power supply system from damage. By disconnecting the power supply circuit of the abnormal load 5 in time, the fault can be prevented from expanding and potential losses can be reduced. At the same time, the rapid response capability of the microcontroller also ensures the safety and stability of the system.

[0071] The use of a microcontroller as the control module 4 has the following advantages: (1) Intelligent control: The microcontroller can autonomously analyze and judge the status information of the load 5, and control the opening and closing of the electronic switch 3 according to the judgment result, thus realizing intelligent control. (2) Fast response: The microcontroller has high-speed processing capability and can respond quickly to status information, disconnect the power supply circuit of the abnormal load 5 in time, and ensure the safety of the system. (3) Strong scalability: The microcontroller usually has a wealth of interfaces and functions, and can be easily connected and communicated with other modules, providing convenience for the expansion and upgrading of the system. Therefore, the use of a microcontroller as the control module 4 of the feedback system can realize accurate, fast and reliable power supply circuit control, and improve the safety and stability of the system.

[0072] In some embodiments, the feedback system further includes: an on-board controller 1 , wherein the on-board controller 1 is connected to the control module 4 , and the on-board controller 1 is used to receive the state information synchronized by the control module 4 , and control and schedule the control module 4 .

[0073] The introduction of the vehicle controller 1 adds new functions and levels to the entire system. As a higher-level control center, the vehicle controller 1 not only receives the load 5 status information synchronized from the control module 4, but also controls and schedules the control module 4. The vehicle controller 1 can make the entire feedback system more flexible, intelligent and efficient.

[0074] The vehicle controller 1 receives the state information of the load 5 synchronized from the control module 4 in real time through the connection with the control module 4. The state information includes the current state, voltage state, etc. of each load 5, reflecting the working state and performance of the load 5.

[0075] The vehicle-mounted controller 1 has the ability to dispatch the control module 4. It can send instructions to the control module 4 according to actual needs, adjust the parameter settings or working mode of the control module 4 to meet different power supply requirements.

[0076] As a higher-level control center, the vehicle controller 1 can comprehensively consider the operating status and performance of the entire power supply system and coordinate and optimize multiple control modules 4. Through reasonable scheduling and control, the goals of efficient use of energy, reduced energy consumption, and extended equipment life can be achieved.

[0077] In actual applications, the vehicle controller 1 will perform real-time scheduling and control of the control module 4 according to the status information of the load 5 and the needs of the system. For example, when a load 5 is abnormal, the vehicle controller 1 can receive an abnormal signal from the control module 4 and disconnect the power supply circuit of the load 5 through the control module 4. At the same time, the vehicle controller 1 can also adjust the power supply strategy of other loads 5 according to the overall operating status of the system to ensure the stability and safety of the power supply system.

[0078] In addition, the introduction of the on-board controller 1 also makes the entire feedback system easier to manage and maintain. The administrator or operator can monitor and manage the entire power supply system through the on-board controller 1, and realize functions such as remote control and fault diagnosis. This greatly improves the reliability and usability of the system. The addition of the on-board controller 1 makes the feedback system more intelligent and flexible, which can better meet the power supply needs of unmanned vehicles or other equipment, and improve the overall performance and reliability of the system.

[0079] In some embodiments, the feedback system further includes a conversion module, which is used to convert the voltage of the target power supply 2 into a target voltage adapted to each load 5 .

[0080] Adding a conversion module to the feedback system can ensure that the voltage of the target power supply 2 can adapt to the target voltage of each load 5. The main function of the conversion module is to convert the voltage of the target power supply 2 into the target voltage required by each load 5. This usually involves voltage up and down conversion to adapt to the operating voltage range of different loads 5. Through the conversion module, it can be ensured that each load 5 can obtain a stable and adaptive power supply, thereby improving the working efficiency and stability of the load 5.

[0081] The conversion module realizes voltage conversion through internal circuit design and electronic components according to the instructions of the control module 4 and the voltage requirements of the load 5. It may use a transformer, a switching power supply or other voltage conversion technology, customized and optimized according to the specific application scenario and the characteristics of the load 5. The conversion module is closely connected to the control module 4, and the control module 4 sends a corresponding control signal to the conversion module according to the status information and voltage requirements of the load 5. After receiving the signal, the conversion module adjusts the size and stability of the output voltage according to the preset algorithm and parameters to meet the requirements of the load 5.

[0082] In the embodiment of the present application, the conversion module can be a direct current-direct current converter, also known as a direct current chopper, which converts a fixed direct current voltage into a variable direct current voltage. The vehicle power supply is generally 12VDC or 24VDC, and there is also 48V, while the voltage of general vehicle electrical appliances is 5VDC, 12VDC or 24VDC, which are all direct current (DC). When it is necessary to power these electrical appliances, a DCDC converter is required. The function of the DCDC converter is to convert these different levels of voltage into the voltage level required by the electrical appliances.

[0083] In some embodiments, the load 5 includes at least one of a radar, a parking system, a camera, a vehicle controller 1 , and an LED.

[0084] In the feedback system, the load 5 refers to a device or component that needs power to perform its function. The load 5 may include at least one of a radar, a parking system, a camera, a vehicle controller 1, and an LED.

[0085] The feedback system collects the status information of these loads 5 in real time, and controls the on and off of the power supply circuit based on this information to ensure that each load 5 can obtain a stable and adaptive power supply. When a load 5 is abnormal, the feedback system can disconnect its power supply circuit in time to prevent the fault from expanding and protect the safety of the entire power supply system.

[0086] In addition, through the scheduling and control of the control module 4 by the on-board controller 1, the feedback system can also adjust the power supply strategy according to actual needs, optimize energy utilization, and improve the efficiency and reliability of the entire system.

[0087] In summary, radar, parking system, camera, vehicle controller 1, LED and other loads 5 play their respective roles in unmanned vehicles or other equipment, and the feedback system ensures that these loads 5 can work stably and efficiently by accurately controlling the power supply circuit and status monitoring.

[0088] In some embodiments, the vehicle controller 1 communicates via a vehicle communication bus 8. The vehicle communication bus 8 includes at least one of CAN, Ethernet, and RS485.

[0089] As a core component in the vehicle, the vehicle controller 1 is responsible for coordinating and managing the work of various systems. In order to ensure fast and accurate transmission of information, the vehicle controller 1 communicates through the vehicle communication bus 8. The vehicle communication bus 8 can build an efficient information transmission network inside the car, so that data and control instructions can be exchanged in real time between various modules.

[0090] Among them, CAN bus is a communication protocol widely used in the automotive field, which has the characteristics of high reliability, real-time performance and flexible network topology. CAN bus can effectively support distributed control and real-time control, so that the vehicle controller 1 can obtain the status information of each module in real time and respond quickly.

[0091] The Ethernet communication protocol is one of the core technologies of modern local area networks. It is simple, flexible and scalable. In vehicle communication systems, Ethernet can be used to achieve high-speed and stable data transmission, supporting multiple transmission rates and different types of Ethernet protocols. This enables the vehicle controller 1 to exchange data efficiently with other modules and realize complex control functions.

[0092] RS485 communication protocol has the characteristics of high speed, long distance and strong reliability, and is suitable for long-distance data transmission. In the vehicle communication system, RS485 can be used to connect modules that require long-distance communication to ensure reliable data transmission.

[0093] Therefore, the vehicle controller 1 communicates through the vehicle communication bus 8, and uses communication protocols such as CAN, Ethernet, and RS485 to achieve efficient and reliable information transmission between various modules in the vehicle. This communication method not only improves the overall performance of the vehicle, but also provides strong support for advanced technologies such as intelligent driving and vehicle networking.

[0096] First, this solution collects the current and voltage status of each load in real time through the signal collection module, providing the control module with rich status information. This enables the control module to more accurately judge the working status of the load and disconnect the corresponding electronic switch in time under abnormal conditions, thereby effectively preventing the expansion of faults and protecting the safety of the entire power supply system.

[0097] Secondly, the introduction of the on-board controller enhances the intelligence and flexibility of the system. Through the connection with the control module, the on-board controller can receive status information and dispatch the control module to coordinate and optimize the entire power supply system. This not only improves energy efficiency, but also enables the system to flexibly adjust the power supply strategy according to different needs to meet the diverse power supply needs of unmanned vehicles or other equipment.

[0098] In addition, the addition of the conversion module enables the system to adapt to the voltage requirements of different loads. By precisely controlling the size and stability of the output voltage, the conversion module ensures that each load can obtain a stable and adaptive power supply, thereby improving the load's operating efficiency and stability.

[0099] Finally, through the vehicle communication bus, the on-board controller can achieve efficient and reliable information transmission with other modules. The application of communication protocols such as CAN, Ethernet, and RS485 ensures the real-time and accuracy of data, providing a strong guarantee for the stable operation of the system.
