Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the implementations of the present invention, and not all implementations, and all other embodiments obtained by those skilled in the art without any inventive work are included in the scope of the present invention.
As shown in figure 1, a new forms of energy passenger train air conditioner panel that possesses remote upgrade function, including whole car gateway 1 and air conditioner controller 7, include MCU4, memory chip 3, outer CAN communication interface 5 and interior CAN communication interface 6 in the air conditioner panel 2, wherein, memory chip 3 and MCU4 communication connection, MCU4 is through outer CAN communication interface 5 and whole car gateway 1 communication connection, MCU4 is through interior CAN communication interface 6 and air conditioner controller 7 communication connection.
The MCU4 is in communication connection with the memory chip 3 through an SPI protocol or a USB protocol. The SPI protocol is an abbreviation of a Serial Peripheral Interface, is a high-speed, full-duplex and synchronous communication bus, only occupies four wires on pins of a chip, saves the pins of the chip, saves space on the layout of a PCB, provides convenience, and has the characteristics of simplicity and easiness in use.
The USB bus is used as a high-speed serial bus, has extremely high transmission speed and can meet the application environment requirement of high-speed data transmission, and has the advantages of simple power supply, convenient installation and configuration, simple and easy expansion port, diversified transmission modes and good compatibility.
The memory chip 3 is a Flash chip or an EEPROM chip.
And the outer CAN communication interface 5 is in communication connection with the whole vehicle network through an OTA protocol format.
The number of the air conditioner controllers 7 is at least one.
The inner CAN communication interface 6 is in communication connection with the air conditioner controller 7 through a CAN _ BOOT protocol format.
The MCU4 is electrically connected with the outer CAN communication interface 5 and the inner CAN communication interface 6 through CAN communication protocols.
The upgrading process of the new energy bus air conditioner panel with the remote upgrading function is as follows:
when the new energy passenger car air conditioner has the demand of long-range upgrading function, MCU4 passes through outer CAN communication interface 5 and whole car gateway 1 communication connection, whole car gateway 1 acquires the upgrade package file that needs to carry out the upgrading, and transmit the upgrade package file to air conditioner panel 2 through outer CAN communication interface 5 through OTA protocol format, MCU4 in air conditioner panel 2 writes the upgrade package file into memory chip 3 and saves, memory chip 3 is after the storage of upgrade package file is accomplished, air conditioner panel 2 communicates with whole car gateway 1 through outer CAN communication interface 5 once more, give the whole car instrument with air conditioner upgrading information forward through whole car gateway 1, whole car instrument reminds the customer to upgrade air conditioner software.
After the customer confirms the upgrade, the air-conditioning panel 2 backs up the existing software in the air-conditioning panel into the storage chip 3 through the MCU4, the storage chip 3 is partitioned, and the backup software before upgrade and the upgrade package file are stored in different partitions of the storage chip 3.
After the backup is finished, the MCU4 reads the upgrade package file from the storage chip 3 to finish the upgrade of the air conditioner panel 2, and after the upgrade of the air conditioner panel is finished, the MCU4 finishes the upgrade of the air conditioner controller 7 according to the format of the CAN _ BOOT protocol through the inner CAN communication interface 6.
