Tooth unit, first bluetooth unit and the second bluetooth unit are made of MCU, bluetooth module and associated peripheral circuits, MCU
Serial communication is used between bluetooth module.
The main control unit, GSMR voice data converting unit, GPS positioning unit, recording unit, between station units
It is connected using dual bus, the dual bus includes the main channel CAN and the spare channel CAN.
The GSMR voice data converting unit includes CMX7261 chip and STM32 series CPU, and the two passes through peripheral hardware
Interface connection, the two are connected by Peripheral Interface.
The main control unit includes the MCU of STM32 series.
The recording unit includes ARM Cortex-A8 microprocessor and operational amplifier circuit, is stored for data.
The station units are the locomotive station with tri- kinds of frequencies of 400MHz, 450MHz, 800MHz.
Compared with prior art, the utility model has the advantage that
(1) device Host end is by the way of backboard plate, while host side and human-computer interaction end use Bluetooth transmission, real
Wireless penetration communication is showed.The artificial assembling process of numerous transmission cables is eliminated, reduces cost of labor, while having matched day
The railway demand opened up increasingly.
(2) plant maintenance is easier to realize: the maintenance of wired communications links need to be along the inspection of line, when failure, generally
It is difficult to find out fault point in time, and bluetooth unit need to be only safeguarded using wireless data transmission mode, when failure then can be quick
Reason is found out, restores route and operates normally.
(3) Bluetooth technology can manage data and voice transmission simultaneously, meet the design requirement of this equipment.
(4) rate of breakdown as caused by single channel, master channel failure are effectively reduced using active and standby dual CAN bus channel
When, alternate channel can be switched in time, and equipment is kept to work normally.
Detailed description of the invention
Fig. 1 is the utility model locomotive wireless communication device systems block diagram.
