Brief description of the drawings
Accompanying drawing is used for providing a further understanding of the present invention, and a part for constitution instruction, with
Embodiments of the invention are used to explain the present invention together, are not construed as limiting the invention.In accompanying drawing
In:
Fig. 1 is schematic structural view of the invention;
In figure:1- acquisition controls mainboard module, 2- acquisition control slave plate modules.
Embodiment
Returned as shown in figure 1, the buoy modularization acquisition system based on CAN is attempted by CAN
Lu Shang, CAN loop two are terminated with terminal resistance, acquisition system include respectively with CAN simultaneously
The acquisition control mainboard module 1 and acquisition control slave plate module 2 connect, acquisition control mainboard module
1 and acquisition control slave plate module 2 on be provided with pre-power supply module and communication interface modules, gather
The output signal Acquisition Circuit of gathered data sensor, output are provided with control slave plate module 2
The sensing data that some signals of signal acquisition circuit are obtained by slave collection terminal passes through CAN communication
Interface is transferred on the acquisition control mainboard module 1 in CAN.Buoy modularization of the present invention
Acquisition system data acquisition is used based on embedded technology, CAN technology, utilizes CAN
Realize and the function of acquisition control mainboard module 1 and acquisition control slave plate module 2 division data are adopted
Collection processing, have it is distributed, can intelligent expansion, maintainable strong, real-time, low-power consumption, height
The characteristics of reliability.
It is provided with what is do not lost after the various arrange parameters of storage power off on acquisition control mainboard module 1
EEROM and the RTC clock with the time on guarantee buoy and the time consistency of bank station receiving terminal.
Above-mentioned acquisition control mainboard module 1 has the USB master that can be operated to the file in USB flash disk
Control functional module, above-mentioned acquisition control mainboard module 1 collection Wave Data, GPS location and with
Bank station communication data transmits.
To improve interference free performance, ensure reliability, pre-power supply module is insulating power supply module.For
The influence of earth potential difference and wire coupled interference is effectively reduced, communication interface modules is isolation communication module.
Acquisition control mainboard module 1 and acquisition control slave plate module 2 are STM32 processors, STM32
Processor uses Cortex-M3 kernels as control core.STM32 series based on aim at require high-performance,
The ARM Cortex-M3 kernels that low cost, the Embedded Application of low-power consumption specially design.It is enhanced
STM32F103 series clock frequencies reach 72MHz, are performance highest products in like product.Adopt
The input and output of integrated digital amount, analog input interface, CAN in collection control main frame plate module 1,232
Communication interface, EEROM and USB interface.
