Abstract

The invention discloses a portable fault diagnosis tester applied to a petrochemical production device, comprising an instrument shell, a hardware mainboard, a CPU (Central Processing Unit), a memory, a hard disk, a power supply, a rechargeable battery, a minisize liquid crystal display, a display card, a minisize keyboard, various communication interfaces, a plugin multi-path AD/DA data collector and the like. The fault diagnosis tester can uninterruptedly collect on-site data all day long through simple system arrangement, and the sampling frequency can be set. The invention has small volume, light weight and convenient carrying, solves the bottleneck problem that the fault diagnosis technology is applied to a practical industrial field, has the advantage that the fault diagnosis testercan be used after a network cable is plugged especially for a petrochemical production device provided with a DCS system or a PLC (Programmable Logic Controller) or an intelligent instrument, therebythe invention is very convenient to use.

Description

technical field [0001] The invention belongs to the technical field of fault diagnosis, in particular to a portable fault diagnosis instrument applied to petrochemical production equipment. Background technique [0002] The petrochemical industry occupies a very important position in the national economy and is a pillar industry of the national industrial system. Because petrochemical production equipment is flammable, explosive, toxic, and high-temperature and high-pressure, if it fails, it will lead to serious consequences such as explosion, fire, and poisonous gas leakage. serious problems facing society. How to make these production devices run safely and normally, give enough strong early warning information before the failure occurs, and try to eliminate the hidden danger of failure in the bud, has become a research hotspot in the field of science and technology in recent years. [0003] Fault detection and diagnosis technology has been developed for decades, and man...
