Specific embodiment
Feature of the present utility model and principle are described in detail below in conjunction with accompanying drawing 1-4, illustrated embodiment is only used for
The utility model is explained, not protection domain of the present utility model is limited with this.
With reference to Fig. 1, Fig. 2, axle identifying system is used in car load dynamic weight calculation, and the system contains basic weighing platform 5, axle identification sensor
1, axle identification carrier 2, axle identification controller 3, the output end of the signal of axle identification sensor 1 is known with the axle of axle identification controller 3
Other device signal input part connection, is made up of, the axle vertical with direction of traffic per axle identifier all the way four axle identification sensors 1
Identifier carrier 2 is per the axle identification sensor 1 of side two and is unified into signal all the way.
Contain processor, channel acquisition circuit, display driver circuit, button drive circuit, power supply in axle identification controller 3
Change-over circuit, RAM memory circuit, eeprom memory circuit, FLASH memory circuit, the signal of axle identification sensor 1 it is defeated
Go out end be connected with the axle identification signal input part in channel acquisition circuit, axle in channel acquisition circuit recognize signal output part and
The serial data mouth connection of processor, 7 cun of LCD displays are connected with the display interface of processor by display driver circuit, are pressed
Keyboard film is connected by button drive circuit with the keyboard interface of processor, RAM memory circuit, eeprom memory circuit and
FLASH memory circuit is connected with the storage mouth of processor, and power-switching circuit is processor, channel acquisition circuit, shows and drive
