Oil quality monitoring and control circuit of hydraulic equipment

Abstract

The invention discloses an oil quality monitoring control circuit of a hydraulic device. The oil quality monitoring control circuit of the hydraulic device comprises an interface terminal, a power supply circuit, an oil quality sensor, a CAN transmitting-receiving circuit, an LM3S2965 control chip, a Nixie tube displaying circuit, an isolation circuit, a relay circuit, a reset circuit, a clock circuit and a key circuit. The oil quality monitoring control circuit of the hydraulic device has the advantages that real-time monitoring is carried out and four parameter data, namely the temperature, the dynamic viscosity, the density and the dielectric constant, of hydraulic oil are analyzed, classified and sorted; secondly, displaying is carried out, the data are analyzed, classified and sorted and then converted into the corresponding display data and the display data are displayed through a Nixie tube; thirdly, output is protected, the sorted and classified data are compared with a protection value set through a key and calculated, and when the data are larger than the protection value, a switching value signal is output to remind or control the hydraulic device to stop. Compared with a traditional manual oil quality detection method, the device has the advantages of high efficiency, high real-time performance, high reliability, high stability, good compatibility, simple installation and the like.

Description

technical field [0001] The invention relates to an oil quality monitoring and control circuit for hydraulic equipment. Background technique [0002] In recent years, the rapid improvement of my country's industrial technology level has led to the improvement of the mechanization of the mining industry, especially the mining hydraulic equipment has been widely used. The traditional method of artificially detecting the oil quality in hydraulic equipment is very random, the judgment method is single, and the data is inaccurate. The loss of hydraulic equipment during long-term operation affects the quality of hydraulic oil. If the hydraulic oil is not replaced through monitoring in time, it may cause blockage of oil pipes, cause safety accidents, and threaten the personal safety of miners. Contents of the invention [0003] The purpose of the present invention is to provide an oil quality monitoring control circuit for hydraulic equipment. [0004] The technical solution of ...
