Wherein, described data acquisition interface is serial data interface, described data reception module is the serial data receiver module, described host computer interface is USB interface, described data transmission module is the usb data transport module, described power transfer module is the direct supply modular converter, and described central control module is fpga chip.
Simultaneously, this is applied to also be provided with the first interface insulation blocking module in the described data acquisition interface in the data collection and analysis device in the digital control system, and the described first interface insulation blocking module is anti-surge protection circuit; Also be provided with the second interface insulation blocking module in the described host computer interface, this second interface insulation blocking module is anti-surge protection circuit.
Moreover, this is applied to also be embedded with power light on the shell in the data collection and analysis device in the digital control system, and described power light is connected with described power transfer module.
In the middle of reality was used, data collection and analysis device of the present invention was made up of shell, data acquisition board and supporting software.Software comprises that the USB of host computer drives and finish the software of data analysis and interactive function.Here only shell and hardware circuit part are elaborated.
Have power light, serial line interface and USB interface on the shell.Comprise DC-DC(DC-to-dc conversion on the data acquisition board) power transfer module, serial signal processing module, usb data transport module, interface insulation blocking module, power supply monitoring module.
(1) kernel control chip on the data acquisition board is a kind of programmable FPGA(field programmable gate array) chip, it is by programmed control hardware, realize serial data collection and conversion, and and usb data transmission chip communication, data are sent to analyzing and processing on the PC by usb protocol.The advantage of fpga chip is can executed in parallel, sends while gather.
(2) comprise a usb data transmission chip in the collector, be used for converting bus data to the USB bag, and communicate by letter bi-directional transfer of data with PC from equipment as USB.
