According to above deficiency, the utility model provides that a kind of structure is simple, strong interference immunity and the high-speed and large-capacity data acquisition storage system of stable performance.
For achieving the above object, the utility model high-speed and large-capacity data acquisition storage system, main contents are: comprise input power, on board supply DC/DC, status indicator lamp, microcontroller, host computer, CPLD, simulating signal amount, parallel A/D converter, data buffer FIFO, level conversion/bus switch and storer FLASH, it is characterized in that, described on board supply DC/DC is connected with input power and microcontroller respectively, described status indicator lamp is all connected with microcontroller with CPLD, described host computer, data buffer FIFO is connected with microcontroller with level conversion/bus switch, described parallel A/D converter respectively with CPLD, simulating signal amount is connected with data buffer FIFO, described data buffer FIFO is connected with level conversion/bus switch, described level conversion/bus switch is connected with storer FLASH.
As preferably, described host computer is mutual with microcontroller by USB or bluetooth etc.
As preferably, described microcontroller is dsp controller.
The utility model beneficial effect is: structure is simple, strong interference immunity and stable performance, applied widely, not by harsh environmental effects.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals:
1-input power, 2-on board supply DC/DC, 3-status indicator lamp, 4-microcontroller, 5-host computer, 6-CPLD, 7-simulating signal amount, 8-walks abreast A/D converter, 9-data buffer FIFO, 10-level conversion/bus switch, 11-storer FLASH.
Embodiment
Below in conjunction with drawings and Examples, the utility model embodiment is described:
These system main contents are: comprise input power 1, on board supply DC/DC 2, status indicator lamp 3, microcontroller 4, host computer 5, CPLD 6, simulating signal amount 7, parallel A/D converter 8, data buffer FIFO 9, level conversion/bus switch 10 and storer FLASH 11, it is characterized in that, described on board supply DC/DC 2 is connected with input power 1 and microcontroller 4 respectively, described status indicator lamp 3 is all connected with microcontroller 4 with CPLD 6, described host computer 5, data buffer FIFO 9 is connected with microcontroller 4 with level conversion/bus switch 10, described parallel A/D converter 8 respectively with CPLD 6, simulating signal amount 7 is connected with data buffer FIFO 9, described data buffer FIFO 9 is connected with level conversion/bus switch 10, described level conversion/bus switch 10 is connected with storer FLASH 11.
Described host computer 5 is mutual with microcontroller 4 by USB or bluetooth etc.
In this system when by the number of accepting and believing by A/D converter 8 Collect conversion after, first be transported in data buffer FIFO 9, the level translator of data bus is closed again by microcontroller 4, abdicate storer FLASH 11 data bus, realize writing after sense data in storer FLASH 11 from FIFO 9 simultaneously; When needs during sense data, now make the output terminal of FIFO 9 invalid and are high-impedance state, after sense data, utilize USB interface to send to host computer 5 by microcontroller 4 from storer FLASH 11 from storer FLASH 11.
By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
