Flowmeter fault detection system

Abstract

The invention discloses a flowmeter fault detection system, which comprises a first control module, a second control module, a monitoring sampling module, an environment sampling module, a diagnosis pre-judgment module, a scheme sequencing module and a data optimization module. The diagnosis pre-judgment module is convenient for users and production plant engineers to check fault reasons and solutions through a mobile terminal, the engineers do not need to go to the site to guide debugging, the increase of labor cost and production halt cost caused by unavailable use on site is reduced, and the scheme sequencing module sorts the fault reasons and solutions of the flowmeter, a user can conveniently, quickly and precisely find a real solution, problems can be solved in an extremely short time, subsequent fault system optimization is facilitated, the data optimization module compares a user feedback book with a scheme given by the system to obtain the fault detection capability of the system, and meanwhile, an original database is supplemented according to data fed back by the user, and then the fault detection capability of the system is optimized.

Description

technical field [0001] The invention relates to the technical field of flowmeters, in particular to a flowmeter fault detection system. Background technique [0002] Flowmeter is one of the four process instruments of temperature, pressure, flow, and level, and is widely used in various industries and various process automation sites. Since the flowmeter is a field instrument, it must be applied in the field, and its performance is closely related to the field application environment. Therefore, in order to give full play to the performance of the flowmeter, the field environment and usage status must be considered. [0003] At present, the flowmeter has the functions of flow sensor sampling, signal output remote transmission display and flow sensor self-diagnosis. There is no monitoring and diagnosis of the environment and signal output monitoring and diagnosis functions. Therefore, when the general flowmeter is applied, it needs to go through several steps. The flowmeter...

Problems solved by technology

Due to human factors in the middle, it may lead to problems such as wrong installation method, wrong parameter setting, wrong wiring method, etc. Since the on-site personnel do not know much about the use of the flowmeter, it is difficult to solve the on-site problem by themselves, and it is necessary to contact the manufacturer to assign an engineer to the site Guided debugging, resulting in increased labor costs and increased production stoppage costs caused by unusable sites
