MATEC Web of Conferences, Jan 2016

In order to improve trainees’ operational quality of static test of guidance station of one antiaircraft missile, a static testing simulator is necessary to gain the goal. It is obvious that the key problem of developing the simulator is how to generate the static testing signals of the simulator. Aiming to solve the problem, at first, the paper adopts a standard called signal testing definition(STD), which is applied to describe simulating signals used for static testing simulation of guidance station of one antiaircraft missile; then those simulating signals for the static testing simulation are implemented based on the platform Labwindows/CVI, and D/A converters are employed for generating physical static testing signals, which are outputted through operational panels or interfaces of the static testing simulator. So the mentioned process could be helpful to realize the static testing simulator of guidance station of one antiaircraft missile.

In order to improve trainees’ operational quality of static test of the guidance station of one antiaircraft missile, a static testing simulator is necessary to gain the goal. It is obvious that the key problem of developing the simulator is how to generate the static testing signals of the simulator. The paper tries to solve the key problem to help develop the simulator. 2 Simulating requirements analysis The static test of the guidance station of one antiaircraft missile has a number of 320 plus test project, it is one of the equipment daily maintenance project in order to test whether working state of the equipment is normal, The method is to apply incentives in different testing points of the equipment, then to measure corresponding outputs to judge state of the equipment. Therefore, the realization of the static testing simulator or test simulating function is to produce the various all kinds of response signals of the equipment. According to the characteristics of the static testing training and requirements of the guidance station of one antiaircraft missile, analysis on simulation requirements would be on the following three facets for developing the static testing simulator of one antiaircraft missile. 2.1 Classification of simulating signals ( 1 ) Transient voltages and currents: the initial voltage and current for the equipment; ( 2 ) The DC voltages and currents: the stable voltage and current for the equipment; ( 3 ) AC voltages: output information, noise and other signals; ( 4 ) Controlled voltages: the equipment controlled voltage; ( 5 ) Resistance parameters: circuit’s resistance of the equipment, breakover resistance, etc. (6) Complex waveform signals: the rectangular wave with adjustable width or frequency modulation etc. controlled by the incentive voltage or power time, as well as various instruction outputting, signals such as pulse front and back edge etc.; (7) Sound and light signals: sound and light output when the equipment works; (8) The state signals: they are controlled by frequency, voltage, time, or other inventive signals, in other words, they are changing signals of controlled state or time; (9) Visual signals: focus changing, target, capture line, self-check lamp, etc. (10) Other signals: output signals of the signal generator without power, self-check signal of voltage stabilizer circuit, etc. 2.2 Analysis on signal relationship The static testing operation of the equipment is not only to achieve the simulation of various signals or parameters, but also to simulate logical function of the actual system, signal control relationship, etc., and analysis and identification on various incentives. ( 1 ) Relationship among the launching control program and the control instructions; MATEC Web of Conferences ( 2 ) Relationship among information signals, serial data and instructions; ( 3 ) Visual signals and detecting states; ( 4 ) Relationship between serial commands and instructions; ( 5 ) Control relationship among other signals. 2.3 Signal stability ( 1 ) AC voltage: 2.5% of the nominal value; ( 2 ) DC voltage: 2% of the nominal value; ( 3 ) DC current: 1.5% of the nominal value; ( 4 ) Frequency/time: 0.1% of the nominal value; ( 5 ) Insulating resistance: 1% of the nominal value; (6) Coefficient of instructions: 1% of the nominal value. 3 signal description and modeling One signal of static test of the guidance station of one antiaircraft missile is selected as an example, with which the method of signal modeling and generating in the paper is depicted in detail. The selected signal waveform is shown as Figure 1. 3.1 Signal simulating model based on signal testing definiti (...truncated)
