So that the manner in which the features and techniques of the disclosed embodiments can be understood in more detail, a more particular description of the embodiments of the disclosure, briefly summarized below, may be had by reference to the appended drawings, which are not intended to be limiting of the embodiments of the disclosure. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may still be practiced without these details. In other instances, well-known structures and devices may be shown simplified in order to simplify the drawing. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 1 is a schematic structural diagram of a rack system of an ADAS device according to an embodiment of the present application. As shown in connection with fig. 1, a rack system of an ADAS device may include: the test bench 1, the power supply module 2, the control module 3, the communication module 4 and the detection module 5, the power supply module 2, the control module 3 and the communication module 4 are integrated on the test bench 1, and the power supply module 2 is electrically connected with the control module 3, the communication module 4 and the detection module 5.
The power supply module 2 is used for supplying power to the control module, the communication module and the detection module.
In the testing process of ADAS equipment, a primary vehicle battery is generally adopted for system power supply, but when a vehicle is flameout or the primary vehicle battery is in a power shortage state, the power supply to a rack system cannot be carried out, if the situation occurs in the ADAS testing process, the testing stability and efficiency of the ADAS can be affected due to unstable power supply in the testing process. Therefore, in this embodiment, by adding the power supply module to the ADAS rack system, the power supply module can continuously supply power to other modules in the rack system, so as to ensure the stability of the power supply, thereby improving the stability of ADAS debugging, testing and collection.
In an alternative embodiment, since the control module includes an ultrasonic controller, a domain controller, an industrial personal computer, and the like, and the ultrasonic controller, the domain controller, and the industrial personal computer in the control module need different voltages, the power supply module needs to be capable of providing different voltages at the same time in order to satisfy the normal operating voltages of all devices in the rack system.
Therefore, fig. 2 is a schematic diagram of a power supply module according to an embodiment of the application. As shown in fig. 2, the power supply module 2 includes a first battery 21, an inverter 22, a main deconcentrator 23 and a voltage stabilizing module 24, the control module 3 includes an ultrasonic controller 31, a domain controller 32 and an industrial personal computer 33, the first battery 21 is respectively connected with the inverter 22, the main deconcentrator 23, the ultrasonic controller 31 and the domain controller 32, the inverter 22 is connected with the industrial personal computer 33, the main deconcentrator 23 is connected with the detection module 5, and the main deconcentrator 23 is connected with the communication module 4 through the voltage stabilizing module 24.
The first battery 21 is a power source capable of supplying low-voltage power in this embodiment, supplies power to the ultrasonic controller 31 and the domain controller 32 by making electrical connection with the ultrasonic controller 31 and the domain controller 32, and is connected with an inverter, outputting a first voltage to the inverter so that the power supply module 2 can supply more types of voltage to meet the power supply demands of other devices in the rack system.
The inverter 22 is used for converting the first voltage of the first battery 21 into the second voltage to supply power to the industrial personal computer. The inverter 22 may convert the dc voltage to another dc voltage or ac voltage. In industrial control applications, the inverter can ensure that the electric energy of the battery is effectively utilized and provides a required stable power supply for the industrial control computer. The working principle of the inverter is that the input direct-current voltage is converted through a series of electronic devices such as thyristors, power field effect transistors and the like, and the required voltage and current are output. The inverter generally has functions of voltage conversion, current regulation, overload protection, etc., and can ensure stable output voltage and current and protect electronic devices from damage.
For example, in the embodiment of the application, a 220V inverter may be used, where the 220V inverter refers to a device capable of converting a voltage of a direct current power supply (such as a battery and a solar battery) into 220V alternating current to supply power to an industrial personal computer, where the industrial personal computer may include a lidar industrial personal computer and a video acquisition industrial personal computer, and the lidar industrial personal computer and the video acquisition industrial personal computer are arranged in a stacked manner, so that space can be saved. It should be noted that the type of the inverter mentioned above may be selected according to the voltage required by the corresponding device in the gantry system, which is not limited by the present application.
The main splitter 23 is used to split and output a single power signal of the first battery to a plurality of output ports. In this embodiment, since there are a plurality of devices requiring the first battery to supply power in the rack system, in order to ensure that each device or circuit obtains stable power supply, the main splitter may be used to effectively manage the power supply signals, ensuring that each output port obtains stable power supply. In general, a main splitter typically has a plurality of input ports and output ports, and a power signal from a first battery is distributed to each output port by an internal distribution structure. In this way, the power supply signal can be effectively distributed to a plurality of devices or circuits, and multiplexing output and output can be realized. Through the design of the main deconcentrator, the power distribution in the power system can be effectively managed, the power waste and overload condition are avoided, and the stability and reliability of power transmission are ensured. In this embodiment, the main splitter 23 may be specifically connected to the detection module 5 to supply power to the detection module 5, and connected to the communication module 4 through the voltage stabilizing module 24.
The voltage stabilizing module 24 is used for stabilizing the voltage of the output of the main deconcentrator and providing a stabilized output voltage. A voltage regulator module is an electronic device that is commonly used to stabilize an output voltage in a power supply system, ensuring that a stable output voltage is provided when an input voltage fluctuates or a load changes. By using the voltage stabilizing module 24 to stabilize the output voltage of the main deconcentrator, the connected equipment can be effectively protected from voltage fluctuation or unstable power supply, and normal operation and stability of the equipment can be ensured.
In this embodiment, power is continuously supplied through the power supply module 2, specifically, a 220V inverter is used to realize high-low voltage conversion, and a voltage stabilizing module is matched to ensure the stability of the direct current voltage. The stability of power supply in the rack system is ensured.
In an alternative embodiment, the foregoing description may use an on-board battery to power the gantry system, and the power module is used to provide stable power to the gantry system due to flameout and power loss of the on-board battery. Therefore, in order to further improve the use efficiency of the rack system, the vehicle-mounted battery and the first battery can be used together, and the vehicle-mounted battery is used for power supply in the process of running the vehicle and under the condition that the vehicle-mounted battery can be normally used. The system therefore also comprises a second battery 6 and an isolator 7, the second battery 6 being connected to the power supply module 2 via the isolator 7.
In this embodiment, the second battery is an in-vehicle battery. Fig. 3 is a link diagram of a dual battery isolator according to an embodiment of the present application. As shown in fig. 3, the first end of the separator 7 is connected to the positive electrode of the second battery 6, the second end of the separator 7 is connected to the positive electrode of the first battery 21, the first battery, the second battery, and the negative electrode of the separator are connected together and then grounded, and the first battery and the second battery are connected to the domain controller and the inverter, respectively. In this embodiment, the first battery and the second battery are connected to the circuit through an isolator to ensure that their respective circuits are independent of each other. When the second battery fails, the isolator is automatically switched to the first battery, so that the system can be ensured to continuously supply power, and the stable operation and service continuity of the system are ensured. In an alternative embodiment, the isolator 7 is further provided with an electric switch for temporarily disconnecting the power supply and supplying a specific device or group of devices with other power supplies. It should be noted that the second battery of the present application may also be used to charge the first battery, so as to ensure that the power of the first battery remains in a sufficient state, so as to continue to supply power to other devices in the rack system when the second battery is not in use.
In an alternative embodiment, a fuse protection circuit may also be connected in series between the first battery 6 and the isolator 7, and a pre-control switch may also be connected in series between the battery and the domain controller for controlling the switching of the domain controller circuit.
In summary, the rack system provided by the embodiment of the application can use the vehicle-mounted battery to supply power in the running process of the vehicle, when the vehicle is flameout or the battery is in a deficient state, the first battery is used for continuously supplying power, the 220V inverter is used for realizing high-low voltage conversion, the primary vehicle battery is protected by the isolator, and the voltage stabilizing module is matched for ensuring the stability of the direct current voltage, so that the stability of the power supply is ensured, and the stability of the rack system is further improved.
In an alternative embodiment, the inverter 21 needs to be switched manually, but in an actual operation process, a situation that the inverter is forgotten to be turned off after use often occurs, so that resource is wasted and a certain safety hazard exists. In view of this, the embodiment of the present application uses a relay instead of a manual switch of an inverter, so the system further includes a relay and a first switch, the first battery and the second battery are connected with the relay through the first switch, and the relay is connected with the inverter; the relay is used for controlling the starting and closing of the inverter. Fig. 4 is a schematic diagram of connection between a second battery and an inverter according to an embodiment of the present application, and, with reference to fig. 4, the second battery 6 is connected to the 12V relay 9 through the precontrolled switch 8, and the 12V relay 9 is connected to the 220V inverter. The starting and the closing of the inverter are controlled through the 12V relay, so that the inverter is prevented from being forgotten to be closed. It should be noted that, the setting of the relay is related to the voltage of the battery, and in the actual operation process, relays with different specifications can be selected according to the battery.
In an alternative embodiment, since a plurality of modules are integrated on the test bench, the modules have low voltage and high voltage in the running process, putting the low voltage equipment and the high voltage equipment together increases the risk of electrical accidents, and the high voltage power supply can generate a stronger electromagnetic field, when the high voltage circuit is close to the low voltage circuit, the low voltage circuit is interfered, the normal running of the low voltage circuit is influenced, and the stability of the test is influenced. Therefore, fig. 5 is a schematic view of area division of a test bench according to an embodiment of the application, and the test bench can be divided into a high-voltage area and a low-voltage area by combining with fig. 5, where the power supply module is located in the high-voltage area, and the control module and the communication module are located in the low-voltage area.
