Analog quantity automatic check system based on safety instrument

Abstract

The invention provides an analog quantity automatic check system based on a safety instrument. The system comprises a master control computer, a digital module, a programmable resistor, a dielectric withstand voltage tester, an oscilloscope, a programmable direct-current power source, a programmable digital multimeter, a signal generator, a signal conditioning box and a clamp. The master control computer, the digital module, the programmable resistor, the dielectric withstand voltage tester, the oscilloscope, the programmable direct-current power source, the programmable digital multimeter and the signal generator are all connected with the signal conditioning box, and the signal conditioning box is connected with the clamp through a flexible cable. A modularized structure is adopted for the analog quantity automatic check system based on the safety instrument, so that the system is convenient to detach, the measurement range can be expanded, and the system can adapt to different occasions; the check standards are objective and unified, and real-time data acquisition, processing, display and record playback can be achieved; uncontrollable human factors are reduced, and the production quality is guaranteed more reliably due to automation.

Description

technical field [0001] The invention relates to an inspection system, in particular to an analog quantity automatic inspection system based on a safety instrument. Background technique [0002] With the continuous development of automation technology, the accuracy of safety instrument performance testing and the real-time performance of information transmission have been greatly improved, the labor intensity of labor has been reduced, the normal operation of safety instruments has been effectively guaranteed, and safety equipment has been largely avoided. Accidents happen. At the same time, the application of safety automation technology, such as safety detection and monitoring system, safety control system, safety bus, distributed operation and other technologies, provides further safety guarantee for the production process. Safety instruments used in automatic control systems, coal mine production, and oil and gas industries maintain the stable and safe operation of the e...

Problems solved by technology

[0004] (1) Inspection is time-consuming and inefficient;

[0005] (2) The inspectors' long-term inspection will cause eye fatigue, which may make the judgment standards inconsistent;

[0006] (3) The inspection results are determined by individual inspectors based on their own experience, which lacks objectivity
