Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
As it is shown in figure 1, this utility model online upgrading device, including the GPRS module 1 being connected and accessible the Internet
Computer 2.
Need to working environment special and can not the instrument and meter 3 with STM32 as core of field upgrade upgrade time,
GPRS module 1 is connected, as shown in Figure 2 with the instrument and meter 3 being somebody's turn to do with STM32 as core.GPRS module 1 with STM32 is
The serial ports of the instrument and meter 3 of core connects, as it is shown on figure 3, the serial ports of the instrument and meter 3 with STM32 as core sends pin TX
Receive pin RX with the serial ports of GPRS module 1 to connect, the serial ports of the instrument and meter 3 with STM32 as core receive pin RX with
The serial ports of GPRS module 2 sends pin TX and connects, the pin RESET_OUT(pin of the instrument and meter 3 with STM32 as core
RESET_OUT can be any one I/O port not used of STM32F103 series microprocessor, such as: PA0, PB1, PC2 etc.)
Connecting with the reset pin RESET of GPRS module 1, (serial ports of the instrument and meter 3 with STM32 as core receives pin RX and transmission
Pin TX can be that any pair serial ports of STM32F103 series microprocessor receives pin, as: STM32F103ZET6
USART1, PA9 are that serial ports sends pin, and PA10 is that serial ports receives pin；The USART3 of STM32F103VCT6, PB10 are serial ports
Sending pin, PB11 is that serial ports receives pin.The pin RESET_OUT of the instrument and meter 3 with STM32 as core can be
Any one I/O port of STM32F103 series microprocessor, the reset pin RESET Low level effective of GPRS module 1).
When the program of the instrument and meter 3 with STM32 as core needs to update, by the computer 2 of accessible the Internet
Sending upgrade command and program AKU, GPRS module 1 carries out data penetration transmission by wireless network, the instrument with STM32 as core
After instruments and meters 3 serial ports receives the upgrade command that GPRS module 1 serial ports transmits, the pending data such as system reset opening timing device
Receive；Now, if the computer 2 of accessible the Internet has program AKU to send over, GPRS module 1 passes through wireless network
Carry out data penetration transmission after, the serial ports of the instrument and meter 3 with STM32 as core starts to receive more new data and verifies storage；Number
After receiving and verify correctly, program AKU overlay device original code, thus realize the long-range renewal of program.For
Ensureing the reliability of number transmission, the built-in ICP/IP protocol of GPRS module 1 carries out the complete transparent transmission of data.
Transparent transmission mode completely namely realizes, by the Internet, the data transmit-receive that subscriber equipment is built with letter in server.Work
Process: after GPRS module 1 powers on, module actively connects with data center server according to the server address arranged and port,
Can send ID bag to server at once after in connection, ID bag can allow the ID of server identification current block；GPRS module sends
After ID bag, can transparent transmission arbitrary data between server and GPRS module 1, it is ensured that the correctness of data.
As shown in Figure 4, this utility model instrument and meter with STM32 as core based on IAP technology and GPRS module is remote
The bottom Bootloader design frame chart of journey online upgrading device.Instrument and meter 3 program with STM32 as core needs to update
Time, the computer 2 of accessible the Internet just sends upgrade command and program AKU, by GPRS module 1 to carry out data saturating
Passing, instrument and meter 3 serial ports with STM32 as core receives the pending data such as system reset opening timing device after upgrade command
Receive；If now the computer 2 of accessible the Internet has program AKU to send over, counted by the carrying out of GPRS module 1
After transparent transmission, the serial ports of the instrument and meter 3 with STM32 as core starts to receive more new data and verifies storage；Data receiver is complete
After finishing and verifying correctly, program AKU covers original code, thus realizes the long-range renewal of program；If data accept mistake
Losing or data check failure, the instrument and meter 3 with STM32 as core performs source code.
The main control chip of the instrument and meter 3 with STM32 as core is pre-installed this Bootloader, this Bootloader and is used many
Plant calibration technology, ensure the correctness of transmission data to greatest extent；Use bootloader mechanism, even if because of thunder bolt
(power-off, programming Flash is unsuccessfully etc.) causes after upgrade unsuccessfully, and program also can return to the state before upgrading, is unlikely to because of liter
Level failure, causes equipment to paralyse.
