Technical field
The present invention relates to the built-in type multiplex data fusion and reach control and intelligent set, be mainly used in the multi-channel serial port data are carried out fusion treatment and exchange control multichannel data.
Background technology
In the optical measuring device of target range, the data fusion control system is the data information exchange center of device interior, is responsible for timing coordination and data fusion exchange between Control System of Microcomputer and other system.Optical measuring device applied optics image-forming principle is gathered target information and is obtained the live image data.For satisfying equipment real-time follow-up precision, the processing frame frequency of servo-drive system and encoder system is all very high, generally all about 1KHz.But the frame frequency of realtime graphic register system is much lower, about 200Hz.Must guarantee the synchronism of these two kinds of information during the later stage precision analysis, otherwise data will lose actual using value.This just requires multichannel data to merge control system not just simply to interrupt or inquiry mode reception (or transmission) data; And will be benchmark (synchronizing signal that the terminal unification of time system provides) with the image recording system sampling instant; The received code device is at this time data constantly at this equipment angle-data gathered constantly and time system terminal; And then these information are mail to image recording system, promptly receive and send and want strict control timing.
Summary of the invention
The present invention is for solving in the optical measuring device of existing target range, and the frame frequency of multichannel data integration system and realtime graphic register system is asynchronous, causes images acquired and measurement data to be difficult to the problem of stores synchronized,, a kind of built-in type multiplex data fusion control system is provided.
Built-in type multiplex data fusion control system, this system comprises main control unit and auxiliary unit, said main control unit is made up of embedded controller, FPGA, EEPROM, display panel, serial ports expansion chip; Auxiliary unit is formed by driving buffer circuit and interface conversion circuit;
Serial data in the external system is the TTL signal through the interface conversion circuit of auxiliary unit with the RS422 conversion of signals; After driving the TTL signal, said driving buffer circuit is sent to the serial ports expansion chip of main control unit; Said serial ports expansion chip sends look-at-me and is sent to embedded controller through FPGA, and said embedded controller is realized reception and transmission to each road signal through the inquiry to look-at-me; The data line of embedded controller, address wire and control signal are sent to the serial ports expansion chip through FPGA; Said FPGA accomplishes the logic control to read-write, look-at-me, data line and the address wire of serial ports expansion chip; Said display panel is provided with each circuit-switched data parameter that embedded controller sends, and said EEPROM preserves the data parameters that is provided with in the display panel.
Principle of work of the present invention: the present invention is directed to target range optical measuring device images acquired and the real-time stores synchronized of measurement data, the sequential control of multi-channel serial port data and the requirement of information fusion, designed a kind of based on built-in type multiplex data fusion control system.Embedded controller of the present invention adopts arm processor; The built-in Watchdog counter PCLK of described arm processor is as the source clock; Its quantitative property is very high with the fineness of distinguishing the time interval; Utilize this characteristic can produce very precise time time-delay, can realize sequential control through programming.Under the man-to-man mode of serial ports, receive each system's data sent, give each system with data back again after processing is merged through arm processor, accomplish exchanges data.The transmitting-receiving sequential of each circuit-switched data, byte number, communication baud rate etc. are required different according to disparity items; System is designed under the prerequisite of not revising software, through the button in the display panel above-mentioned parameter is provided with; And the parameter that is provided with is kept in the EEPROM, operation is the setting when shutting down last time when guaranteeing start.FPGA accomplishes the logic control of read-write to the serial ports expansion chip, look-at-me, data line, address wire.And receive an outer synchronous signal and a second signal, in FPGA, generate the 200Hz synchronizing signal and pass to ARM and use as look-at-me.
Beneficial effect of the present invention: the present invention at first accomplishes the exchanges data between a plurality of subsystems of optical measuring device; Secondly, time sequence control wants strict control to receive data and the sequential relationship of sending data; At last, the various settings of each road information should have and under the condition that does not change software, carry out intelligent set; That the inventive method has is real-time, sequential is strict, simple and direct-viewing operation, low cost and other advantages, can be applicable to the target range optical measuring device.
