The utility model discloses a communication
protocol converter used for a generator excitation
system, comprising an STM32F407
chip, a CAN module, RS-485 modules, two paths of
Ethernet modules and a B code
time synchronization module, the CAN module is electrically connected with the STM32F407
chip, the CAN module is used for communicating with the generator excitation
system, the RS-485 modules are electrically connected with the STM32F407
chip, the RS-485 modules are used for being connected with an external device supporting an RS-485 protocol, and the two paths of
Ethernet modules are connected with the B code
time synchronization module. The two paths of
Ethernet modules are electrically connected with the STM32F407 chip, one path of Ethernet module is used for communicating with a generator excitation
system, the other path of Ethernet module is connected with an external device supporting an
MODBUS-TCP protocol, the B code
time synchronization module is electrically connected with the STM32F407 chip, and the STM32F407 chip is electrically connected with the STM32F407 chip. And the B code time synchronization module is used for ensuring the time consistency of the communication
protocol converter and the generator excitation system or the external equipment. The utility model has the advantages of being compatible with the generator excitation system and improving the communication efficiency of the generator excitation system and the external equipment.
