Research And Design Of Servo Control System To Shipborne Stabilized-platform

This article is mainly introduced the lamp light landing and system for the helicopter on a warship of the electromagnetic compatibility analysis and design of circuit and realizes. Mainly design three respects design software design and quantitative emulation to describe from the hardware.First of all, have explained the electromagnetic concept that interfered with and present domestic and international technological state, confront with each other electromagnetic to interfere with technology and want work that make introduce the brief one, and analyze in an all-round way in producing the electromagnetic key elements of various fields that interfere with. Propose designing the main point according to the analysis result, realize through the hardware, software circuit and artificial technology. Introduce the detailed one to the artificial software Protel99 of simulation of circuit in the article, propose the overall design of the artificial function of the system on this basis.In hardware design, adopt AT89C52 one-chip computer, utilize 24bitI/O 8255 four of chip at the same time, make system work necessary peripheral chip normally while being other, for example watchdog IC X25045,etc.. I/O chip receive lamps and lanterns of control panel, control order, code choose order and trouble measure trouble message that the board output, at the same time according to fail people order and state, judge, output lamps and lanterns touch off, urge signal, panel synchronous state point out, urge signal, alarm signal, reply signal of showing and chirp transliteration device urge the signal. Put way P1.6 in one-chip computer of location with software in software design, P1.7 in charge of foot set up initial value. Have adopted the corresponding measure in the software to the question that the one-chip computer is relatively prone to when interfered with too, if order redundant, software trap and watchdog technique etc..Finally, the lighting systems to help lower the electromagnetic compatibility for the quantitative analysis, the use of electronic circuit design simulation software Protel99. Use artificial package SIM99 of circuit of software this when the emulation. In the simulation, SIM99 used to map out the specific point of the circuit waveform is more complicated electromagnetic conditions circuits' Dimmer part of the wave through the analysis to determine transformer dimming, as well as silicon devices off the circuit of the impact.
