Sixteen Line Computer Recording Instrument Design And Implementation

Computer recording instrument is a versatile instrument, with corresponding resistive sensor can measure and record, rally, pressure, torque, displacement, the amplitude of changes in parameters such as. Is widely applied to our second artillery missile tests, mainly used to record and print the measured signal curve, simulated flight rudder deviation curve, output curve and other needs to record the signal characteristics.This paper uses embedded computer PC104as control core technology, development as a universal instrument, both for a type of new missile real time recording and printing the measured signal curve, simulated flight rudder deviation curve, output curve, can also be used for other types of missile test curve depicts the work.This paper introduces the structure of the apparatus, hardware and software design; and the interference source, interference of transmission channel, sensitive components such as a few problems in the electronic product solutions and preventive measures are studied and presented their solutions; focus on the design of the amplifying and isolating circuit, and the circuit and the detailed test and application, was conducted for the complete machine matching inspection, assembly welding quality inspection, checking circuit, insulation resistance inspection, insulating strength check of performance parameters such as check test and electric stress screening test and environmental test, in order to verify the stability and reliability of the equipment.This paper also introduces sixteen line recording instrument of computer application, and how to enhance the products anti-jamming ability, is the main interference source, interference of transmission channel, sensitive components and so on several aspects in the electronic product solutions and preventive measures are studied and presented their solutions. At the same time, this article also in detail on sixteen line computer recording instrument reliability indices were calculated, to establish a system reliability model, ratio calculated unit reliability numerically, and the results are analyzed.
