Fig. 2 is the structural representation of the management board that provides of the embodiment of the invention.
[embodiment]
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Core concept of the present invention is: through fpga chip is carried out hardware programming, thereby make it become a main control chip that is exclusively used in managing system of car parking at kernel of internal production of fpga chip with some peripheral logical circuits.
See also shown in Figure 2ly, the management board in the present embodiment in the managing system of car parking comprises:
Special-purpose fpga chip, the duty that is used to inquire about control panel is to control panel transceive data and instruction; All working data in the storage crowd; Be responsible for the management of communication in the crowd; Be responsible in the crowd and outside data sharing and renewal; Operation interface demonstration, mouse and keyboard are controlled; Card management and user management, operator's management etc.; In the time of in being applied to, also be used for being responsible for coordinating the work of whole long-distance transmissions as the management board of administrative center;
Power module comprises the power supply adaptor and the power-switching circuit of series connection, through power-switching circuit and fpga chip, in order to it is supplied power.
Wherein, The fpga chip of above-mentioned special use is made up of 51 super kernels and various functional interface, and functional interface comprises: remote RS485 communication interface, closely RS485 communication interface, IMAQ port, IC/ID card RS485 communication interface, digital video input/output interface, mouse interface, keyboard interface, equipment serial number are provided with port, system encryption chip interface, client encrypt chip interface, online programming interface, clock circuit interface, SDRAM chip interface, SD card and other I/O interfaces.
In addition, fpga chip can through remote RS485 communication interface realize between the crowd communication, through RS485 communication interface closely realize in the crowd communication, through IC/ID card RS485 communication interface and IC/ID card connection with the compatibility that realizes IC-card and ID card, be connected with the realization transmission of video signals with display screen, be connected with the SDRAM chip with realization information stores or the like through a plurality of SDRAM chip interfaces through the digital video input/output interface.In carrying out the crowd, closely during the RS485 communication, adopt 57600bps; When carrying out between the crowd remote RS485 communication, adopt 19200bps; The IMAQ port adopts the RS232 communication modes, and speed is 57600bps.
Because the interface of FPGA is many, applying flexible can be compared with the not general general controls chip of chip (like 51 series monolithics or ARM chip) that FPGA does.Managing system of car parking is irrealizable with 51 single-chip microcomputers; And on port and Video processing, also have some limitation with the ARM single-chip microcomputer, thereby the present invention adopts FPGA to realize, not only is easy to realize, perfect in shape and function; And have stronger stability and a compatibility (can compatible IC-card and ID card); And be not vulnerable to the invasion of virus, low in energy consumption, economy is environmental protection again.
When using fpga chip, just can realize the programming of software through using general C language as main control chip.In software implementing course, can use the C language to make a gui interface, realize patterned operation interface, operation is directly perceived.General other system all can need to use some general operating systems when realizing patterned interface, such as WINCE, LINUX etc., uses these operating systems higher to the requirement of the performance of main control chip and memory size, and the cost of system is just higher certainly.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
