Abstract

The invention relates to an intelligent monitor controller of a multi-mode air compressor, integrating a common monitor controller of the air compressor and a variable frequency speed regulation monitor controller of the air compressor. The monitor controller solves the problem that the traditional air compressor monitor controller has single working mode, is difficult to adapt to the conversion of the working modes of the air compressor and can not work normally. In the invention, when the air compressor adopts a loading and unloading mode to regulate air storing pressure, the monitor controller works under a common monitoring mode; when the air compressor adopts a mode of controlling the rotating speed of a motor in manner of variable frequency speed regulation to regulate the air storage pressure, the monitor controller works in a variable frequency speed regulation energy-saving monitoring mode; the monitor controller can be directly connected with the output signal lines of a temperature sensor and a pressure sensor, and a central control core adopts a DSP (Digital Signal Processor) chip and CAN (Controller Area Network) bus mode to communicate without a sensor transducer. The invention takes DSP as a control core, integrates the common monitor controller of the air compressor and the variable frequency speed regulation monitor controller of the air compressor, does not need an additional controller and has strong function, low cost, high integrity, high reliability, flexible control method and broad market prospect.

Description

technical field [0001] The invention relates to an air compressor detection and control integration device, in particular to a multi-mode air compressor intelligent monitor. Background technique [0002] As a kind of gas compression and transportation equipment, air compressors are widely used in various industries such as mines, roads, civil engineering, geology, building materials, light industry, textiles, and medical treatment. In order to ensure the safe and effective operation of the air compressor, the key operating parameters of the air compressor must be monitored online, mainly including: sensor status, exhaust pressure, exhaust temperature, exhaust volume, motor load, motor temperature and other parameters. During the monitoring process, once an abnormal situation is found, the monitor should automatically alarm or trip the machine. When the air compressor is running, good control of the exhaust pressure is the goal to pursue. For pressure control, there are mai...
