It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

Fig. 1 is a schematic structural diagram of an apparatus for debugging an in-vehicle electronic device according to an embodiment of the present disclosure. As shown in fig. 1, the apparatus for commissioning a vehicle-mounted electronic device includes: a logging section 1, a first interface section 2, a voltage conversion section 3, an interface conversion section 4, and a second interface section 5. One end of the first interface part 2 is connected with an upper computer, and one end of the second interface part 5 is connected with the vehicle-mounted electronic equipment to be debugged. The other end of the first interface portion 2 is connected to the voltage conversion portion 3 and the interface conversion portion 4, respectively. The voltage conversion section 3 is connected to the logging section 1 and the interface conversion section 4, respectively. The logging section 1 and the interface conversion section 4 are connected. The other end of the second interface section 5 is connected to the logging section 1 and the interface conversion section 4, respectively.

Specifically, the upper computer sends a debugging instruction to the vehicle-mounted electronic device through the first interface part 2, the interface conversion part 4 and the second interface part 5. After the vehicle-mounted electronic equipment executes the debugging instruction, the vehicle-mounted electronic equipment sends a debugging result to the upper computer through the second interface part 5, the interface conversion part 4 and the first interface part 2. The log recording part 1 is used for recording the debugging result and/or the log recording part 1 can be used for recording the debugging instruction sent by the upper computer to the vehicle-mounted electronic equipment.

In this embodiment, the apparatus for debugging the in-vehicle electronic device shown in fig. 1 may be specifically a circuit. The circuit includes 5 parts, which are a logging part 1, a first interface part 2, a voltage conversion part 3, an interface conversion part 4, and a second interface part 5, respectively.

In the embodiment, the first interface part in the device for debugging the vehicle-mounted electronic equipment is connected with the upper computer, and the second interface part in the device is connected with the vehicle-mounted electronic equipment to be debugged, so that the upper computer can send a debugging instruction to the vehicle-mounted electronic equipment through the device, the vehicle-mounted electronic equipment can send a debugging result to the upper computer through the device, and the debugging result can also be recorded in the log recording part of the device. That is to say, the device for debugging on-vehicle electronic equipment not only has the function of switching, still has the function of logging, through with switching function and logging function integration in a circuit, has simplified the process of setting up of test environment greatly, has improved the efficiency of software testing to on-vehicle electronic equipment, has reduced the error rate in the test.

On the basis of the foregoing embodiment, optionally, the first interface portion includes a Universal Serial Bus (USB) socket interface, and the USB socket interface is connected to the upper computer; the second interface part comprises a USB plug interface, and the USB plug interface is connected with the vehicle-mounted electronic equipment. Or the first interface part comprises a USB plug interface, and the USB plug interface is connected with the upper computer; the second interface part comprises a USB socket interface, and the USB socket interface is connected with the vehicle-mounted electronic equipment. The USB socket interface is similar to an interface used for inserting a USB flash disk on a computer host, and the USB plug interface is similar to an interface of the USB flash disk.

For example, the first interface part 2 and the second interface part 5 may each comprise a Universal Serial Bus (USB) interface, e.g. a USB Type-C interface. Wherein, the USB interface of being connected with the host computer in the first interface portion 2 can select for use socket (Receptacle), and the USB interface of being connected with on-vehicle electronic equipment in the second interface portion 5 can select for use Plug (Plug), and wherein, on-vehicle electronic equipment specifically can be the car machine. That is, the first interface part 2 may include a USB Receptacle interface. The second interface part 5 may comprise a USB Plug interface. In other embodiments, the USB interface of the first interface portion 2 connected to the upper computer may be a Plug (Plug), and the USB interface of the second interface portion 5 connected to the in-vehicle electronic device may be a socket (recipient), for example, the first interface portion 2 may include a USB Plug interface, and the second interface portion 5 may include a USB recipient interface. That is to say, one of the first interface portion 2 and the second interface portion 5 can be used as a socket, and the other can be used as a plug, so that a debugging person or a testing person can be effectively prevented from connecting the first interface portion 2 and the second interface portion 5 in reverse, for example, the debugging person or the testing person is prevented from connecting the first interface portion 2 to a vehicle machine, and the second interface portion 5 is connected to an upper computer. Therefore, debugging personnel or testing personnel can connect the first interface part 2 to the upper computer and connect the second interface part 5 to the car machine, and fool-proofing is effectively achieved.

For example, when the first interface portion 2 includes a USB Receptacle interface and the second interface portion 5 includes a USB Plug interface, only one USB cable is needed to connect the first interface portion 2 and the upper computer, and the second interface portion 5 is directly connected to the car machine, so that the car machine can be debugged or tested.

In the present embodiment, the first interface part 2 and the second interface part 5 may include USB Type-C interfaces, respectively. The positive and negative line sequence of the USB Type-C interface is completely symmetrical, so that reverse connection or misconnection can be effectively prevented. In addition, the USB Type-C interface can integrate more signals in a smaller size, and optionally, the USB Receptacle interface can follow the USB2.0 interface sequence and protocol. In addition, according to the requirement of communication speed, the USB Receptacle interface can be adjusted to be a USB3.0 interface. The USB Plug interface may not follow the line order definition of the Type-C interface, but customize the signal based on the interface format.

Optionally, the interface conversion part includes: an interface conversion chip; the interface conversion chip is connected with the first interface part through a universal serial bus interface; the interface conversion chip is connected with the second interface part through a multi-path universal asynchronous receiving and transmitting transmitter interface.

As shown in fig. 2, the interface conversion portion 4 includes an interface conversion chip 41, the interface conversion chip 41 is connected to the first interface portion 2 through a USB interface, and the interface conversion chip 41 is connected to the second interface portion 5 through a Universal Asynchronous Receiver/Transmitter (UART). The interface conversion chip 41 may convert one USB interface into multiple UART interfaces. That is, the interface conversion chip 41 is connected to the first interface portion 2 through one USB interface, and the interface conversion chip 41 is connected to the second interface portion 5 through a multi UART interface.

Optionally, the vehicle-mounted electronic device includes a plurality of modules to be debugged; and each universal asynchronous receiving and transmitting transmitter interface in the multi-path universal asynchronous receiving and transmitting transmitter interfaces corresponds to one module to be debugged in the plurality of modules to be debugged.

For example, the vehicle-mounted electronic device may specifically be a vehicle machine, and the vehicle machine may include a plurality of modules, that is, when the vehicle machine is debugged, the plurality of modules of the vehicle machine may be specifically debugged respectively. The number of the UART interfaces converted by the interface conversion chip 41 may be the same as the number of the modules to be debugged of the vehicle device, that is, one UART interface converted by the interface conversion chip 41 may correspond to one module to be debugged of the vehicle device. Optionally, the interface conversion chip is configured to convert one USB interface into 3 UART interfaces for the universal asynchronous transceiver. For example, the car machine includes 3 modules to be debugged, and as shown in fig. 2, the 3-way UART interface is connected to the second interface portion 5. That is, the 3-way UART interface can be connected to the car machine through a USB Type-C interface.

Optionally, the interface conversion chip is configured to convert one USB interface into 6 UART interfaces for the universal asynchronous transceiver. For example, in some embodiments, if the car machine includes 6 modules to be debugged, the interface conversion chip 41 may be selected as a chip with a larger number of conversion paths, for example, expanded to 6 paths, according to the requirement.

The following is a schematic description of a 3-way UART interface. For example, the upper computer is connected to the interface conversion chip 41 through the USB2.0 of the first interface part 2, the interface conversion chip 41 converts the USB2.0 interface into a 3-way UART interface, and the 3-way UART interface is output to the second interface part 5.

For example, a Head Unit (HU) includes a Micro Controller Unit (MCU), a System On Chip (SOC), and a 5G module. As shown in fig. 2, the MCU, the SOC and the 5G module correspond to a UART interface respectively. Taking the MCU as an example, when the upper computer sends a debugging instruction for the MCU to the car machine through the first interface part 2, the debugging instruction reaches the interface conversion chip 41 through the USB2.0 interface between the first interface part 2 and the interface conversion chip 41, the interface conversion chip 41 can convert the debugging instruction from the USB2.0 format to the UART format, and transmit the debugging instruction to the second interface part 5 through the UART interface corresponding to the MCU, and further send the debugging instruction to the car machine through the second interface part 5. Similarly, the debugging instruction that is used for debugging 5G module that the host computer sent sends is sent for the car machine through the UART interface that 5G module corresponds, and the debugging instruction that is used for debugging SOC module that the host computer sent is sent for the car machine through the UART interface that SOC module corresponds. It can be understood that the debugging commands for the MCU, the SOC, and the 5G module sent by the upper computer to the vehicle machine through the first interface part 2 all reach the interface conversion chip 41 through the USB2.0 interface between the first interface part 2 and the interface conversion chip 41, however, the interface conversion chip 41 may transmit the debugging commands for the MCU to the second interface part 5 through the UART interface corresponding to the MCU, transmit the debugging commands for the SOC to the second interface part 5 through the UART interface corresponding to the SOC, and transmit the debugging commands for the 5G module to the second interface part 5 through the UART interface corresponding to the 5G. That is, the interface conversion chip 41 may forward the debugging instructions for the MCU, the SOC, and the 5G module to different UART interfaces respectively. Therefore, debugging instructions aiming at the MCU, the SOC and the 5G module are respectively sent to the vehicle machine through different UART interfaces. Similarly, the car machine can send the debugging results to the MCU, the SOC and the 5G module to the respective UART interfaces corresponding to the MCU, the SOC and the 5G module respectively, the interface conversion chip 41 forwards the debugging results on the different UART interfaces to the first interface part 2 through the USB2.0 interface, and further, the debugging results to the MCU, the SOC and the 5G module are fed back to the upper computer through the first interface part 2. That is, the interface conversion chip 41 can perform format conversion on data on the USB2.0 interface and data on the UART interface, and the interface conversion chip 41 can implement bidirectional data transmission.

Optionally, the logging part includes: the device comprises a plurality of log recording chips and a plurality of storage card seats, wherein each log recording chip is connected with one storage card seat; and each path of UART interface in the multi-path UART interfaces is connected with a log recording chip.

As shown in fig. 2, the Log recording part 1 includes 3 Log recording (Log Recorder) chips and 3 memory card sockets (Micro SD sockets). Wherein, 3 logging chips are respectively recorded as logging chip 0, logging chip 1 and logging chip 2. In the figure, 14 denotes the logging chip 0, 15 denotes the

logging chip

1, 16 denotes the logging chip 2. The 3 memory card sockets are respectively marked as a memory card socket 0, a memory card socket 1 and a memory card socket 2. Memory card socket 0 is denoted by 11, memory card socket 1 is denoted by 12, and memory card socket 2 is denoted by 13. Each logging chip is connected to a storage card socket, for example, the logging chip 0 is connected to the storage card socket 0, the logging chip 1 is connected to the storage card socket 1, and the logging chip 2 is connected to the storage card socket 2.

Taking the log recording chip 0 and the memory Card socket 0 as an example, the log recording chip 0 and the memory Card socket 0 are connected by a Serial Peripheral Interface (SPI) and a Card access detection (CD) line.

Optionally, a memory card is inserted into the memory card socket; the card access detection line comprises a switch, and the state of the switch changes when the storage card is inserted into the storage card socket; the log recording chip comprises a switch state detection circuit, and the switch state detection circuit is connected with the switch; and the debugging result of the vehicle-mounted electronic equipment is stored in the memory card through the serial peripheral interface when the switch state detection circuit detects that the state of the switch changes.

Specifically, a memory card (Micro SD) can be inserted into the memory card socket. The capacity of the memory card is not limited in this embodiment, and may be, for example, 2 to 32G. In this embodiment, a memory card can be inserted into each of the memory card socket 0, the memory card socket 1 and the memory card socket 2.

In addition, as shown in fig. 2, the 3-way UART interface is connected to 3 logging chips through a 3-way UART line. For example, when the car machine sends a debugging result of the MCU to the host computer, the debugging result may be transmitted to the logging chip 0 through the MCU _ RXD1/TXD1, and further, the logging chip 0 stores the debugging result in the memory card of the memory card socket 0. When the vehicle sends the debugging result of the SOC to the upper computer, the debugging result can be transmitted to the logging chip 1 through the SOC _ RXD2/TXD2, and further, the logging chip 1 stores the debugging result into the storage card on the storage card socket 1. When the car machine sends the debugging result of the 5G module to the upper computer, the debugging result can be transmitted to the logging chip 2 through the 5G _ RXD3/TXD3, and further, the logging chip 2 stores the debugging result in the memory card on the memory card socket 2. The debugging result may be recorded as LOG (LOG) data. It is to be understood that the log data is not limited to the debugging result, and may also include debugging instructions, for example.

Specifically, the vehicle-mounted electronic device transmits the debugging result to a log recording chip connected with the UART interface through the UART interface; and the log recording chip transmits the debugging result to a memory card through the SPI.

For example, the car machine transmits the debugging result of the MCU to the log recording chip 0 connected to the UART interface through the UART interface corresponding to the MCU, and the log recording chip 0 transmits the debugging result of the MCU to the memory card on the memory card socket 0 through the SPI.

Specifically, each CD line may include a switch, the state of which changes when the memory card is inserted into the memory card socket. Taking the CD line between the logging chip 0 and the storage card socket 0 as an example, when the storage card is inserted into the storage card socket 0, the on-off state of the CD line changes, for example, from the original off state to the on state, or from the original on state to the off state. When the state of the switch on the CD line changes, the CD line generates level jump.

In addition, the logging chip 0 includes a switch state detection circuit, the switch state detection circuit is connected to the switch on the CD line, and the switch state detection circuit can detect the state of the switch in real time or periodically. When the switch state detection circuit detects that the state of the switch changes, the logging chip 0 can store the debugging result of the MCU into the memory card on the memory card socket 0 through the SPI between the logging chip 0 and the memory card socket 0.

Similarly, the connection mode between the logging chip 1 and the memory card socket 1, the connection mode between the logging chip 2 and the memory card socket 2, and the storage logic of the debugging result received by the logging chip 1 or the logging chip 2 are all similar to these, and are not described herein again.

As shown in fig. 2, the interface conversion section 4 further includes: a first Transient Voltage Super (TVS) Array (Array)42 and a second Transient diode Array 43. The first transient diode array 42 is connected to the USB interface, and the second transient diode array 43 is connected to the multi-UART interface. The first transient diode array 42 and the second transient diode array 43 both support Electro-Static discharge (ESD) protection for the high-speed signal line, and prevent damage to the device during use.

Optionally, the voltage conversion part is configured to convert a first voltage provided by the upper computer into a second voltage, where the first voltage is greater than the second voltage; the second voltage is used for supplying power to the logging part and the interface conversion part.

As shown in fig. 2, the upper machine body may be a Personal Computer (PC). The upper computer can provide a voltage of VBUS _5V for the device for debugging the vehicle-mounted electronic equipment through the first interface part 2, and the voltage of VBUS _5V can supply power to the device in a board. The voltage conversion part 3 may convert VBUS _5V provided from the upper computer into VCC _3V3 voltage. Further, the VCC _3V3 voltage may supply power to the logging section 1 and the interface conversion section 4. VBUS _5V is denoted as the first voltage, and VCC _3V3 is denoted as the second voltage. VBUS _5V represents a voltage of 5V, and VCC _3V3 represents a voltage of 3.3V, that is, the first voltage is greater than the second voltage.

Optionally, the voltage converting part includes: linear voltage regulators or dc-to-dc switching power supplies. For example, the voltage conversion section 3 may be selected as a linear Regulator (LDO). The LDO has the advantages of simple peripheral circuit, small size and low cost. Alternatively, the voltage conversion part 3 may also select a dc-dc switching power supply (DCDC) with higher Current capability and higher efficiency according to the requirement.
