Universal data acquisition system

Abstract

The invention provides a universal data acquisition system. The system comprises a data acquisition device and a upper computer, wherein the data acquisition device comprises a microprocessor, a reusable data acquisition channel, a memory expansion module and an interface module; the microprocessor is connected with the reusable data acquisition channel, the memory expansion module and the interface module respectively; the reusable data acquisition channel is defined with different communication protocols, corresponding communication protocols are selected according to the requirement of practical tests, and different output signals with the same output signal type are transmitted through the same data acquisition channel by using the selected communication protocol; and the data acquisition device is communicated with the upper computer through the interface module. Therefore, the universal data acquisition system has the advantages that sensors with consistent function and same output signal type can reuse the same data acquisition channel, and the safety performance of elevators, pumps, air compressors, ventilators and other mineral machinery and electrical equipment can be tested by using the same data acquisition system regarding different test requirements.

Description

technical field [0001] The invention relates to the field of measurement and control, in particular to a general data acquisition system used for testing the safety performance of mine electromechanical equipment. Background technique [0002] At present, the safety test system of mining electromechanical equipment is developed for specific mining electromechanical equipment. For example, for mine main drainage system, water pump safety performance tester can be used for testing; for mine hoisting system, hoist can be used Safety performance tester and wire rope flaw detector and other equipment for testing. [0003] According to the provisions of the "Coal Mine Safety Regulations", there are many identical or similar test items in the safety performance test system of different mining electromechanical equipment such as hoists and fans, and conventional monitoring devices with similar performance are used in existing monitoring devices. Therefore, resources are wasted, and...
