Abstract

The invention discloses a TST2811 valve signal control analyzer. The TST2811 valve signal control analyzer comprises a current-to-pneumatic (I/P) converter and a controllable constant-current source. A controllable bridge circuit, a strain sensor, a program-controlled signal amplifier and an analogue filter are connected in sequence; a direct-current to direct-current (DC-DC) power supply, an integrated electronics piezo electric (IEPE) sensor signal, a program-controlled signal amplifier and an analogue filter are connected in sequence; two series branches are connected in parallel with a 16-bit analogue-to-digital converter; the 16-bit analogue-to-digital converter, a digital signal processor (DSP), a universal asynchronous receiver/transmitter-to-universal serial bus and computer valve signal test and analysis software are connected in series in sequence; and simultaneously, the two program-controlled signal amplifiers, the controllable bridge circuit, the DC-DC power supply and the 16-bit analogue-to-digital converter are connected in parallel with a singlechip. By the TST2811 valve signal control analyzer, a valve fault can be discovered in time; a large amount of maintenance time is saved; manpower and materials are reduced; and the waste of energy resources is reduced.

Description

technical field [0001] The invention relates to a TST2811 valve signal control analyzer. Background technique [0002] The rapid development of industry in today's world is moving towards automation. The focus of industrial development is energy, chemical industry, steel, transportation, and construction. The application of fluids such as water, gas, and oil is closely related to industrial development. The application of fluids in industry is inseparable from the pipe network system. The net must have valves. To realize the industrial automation management of the pipe network system, it is inseparable from the valve, the actuator in the pipe network system. In order to make the valve more stable and reliable during operation, it is necessary to test and study various parameters of the valve during factory inspection. [0003] The early concept of valve maintenance was to keep the valve working for as long as possible, and if a fault was found, shut down the plant and imm...
