Software Design for Test & Diagnosis System of Universal Portable Infrared Thermal Imaging Equipment

Abstract

This paper analyzes the current status and problems of ensuring the maintenance of the thermal imaging infrared equipment and proposes a software design scheme, algorithm and programming for the test and diagnosis system of universal portable thermal imaging infrared equipment, which provides expert guidance for the detection of comprehensive performance indexes, through the use of fault location, diagnosis and instrument maintenance. Introduction Currently, although massive thermal infrared imaging equipment has been developed and used before, the development of the corresponding portable detection and diagnosis equipment still lags significantly behind, putting the maintenance of the equipment in an extremely concerning position, mainly shown by: (1) Traditional inspection of the comprehensive performance of thermal imaging infrared equipment can only be carried out by the manufacturer or repair facility; (2) Since it is impossible to disassemble the thermal infrared imaging subsystem equipped in the weapon systems and send it for performance index testing, a portable testing equipment on site is required. However, maintenance for such platform thermal imaging infrared systems in the army is still missing at present; (3) Traditional detecting instruments can only detect the performance indexes and cannot discover faults and give recommendations for diagnosis and maintenance, with particularly high requirements placed on the professional skill of the maintenance personnel. They can no longer meet the steadily increasing demands of the army on equipment usage and maintenance tasks. Therefore, there is an urgent need to develop a system capable of conducting timely, rapid and reliable performance testing and diagnosis of the portable thermal imaging infrared equipment. Such a system shall be able to detect on-site the comprehensive performance indexes of the equipment and provide the necessary information references for fault location, diagnosis and maintenance so as to provide a strong assurance of fully-functioning performance of the equipment in battle. The test & diagnosis system software is designed with the functions of testing performance indexes, circuit performance detection, fault diagnosis and maintenance guidance for the thermal infrared imager, as described below: (1) It is able to test the performance indexes of the thermal imaging infrared system, such as MRTD, NETD, MDTD, SNR and Non-Uniformity; (2) It is able to detect the single-sided board; (3) It can conduct intelligent fault diagnosis to the functional component level and locate common faults to the component level; (4) It provides repairing schemes in an intelligent manner and gives guidance for maintenance personnel to carry out troubleshooting. 2nd International Conference on Electrical and Electronic Engineering (EEE 2019) Copyright © 2019, the Authors.
