Electromechanical device abnormal alarm stop control system and control method

Abstract

The invention discloses an electromechanical device abnormal alarm stop control system and a control method. The system comprises a UPS (Uninterrupted Power Supply), a Hall switch, an RC filter and acomparator, wherein the input end of the UPS is connected with the power grid; the output end of the UPS is connected with a switching power supply; the power input end of the Hall switch is connectedwith the output end of the switching power supply; the Hall switch is used for detecting the operating speed of a stirring rod on an electromechanical device; the input end of the RC filter receivesan output signal of the Hall switch; the RC filter comprises a capacitor and a resistor; the resistor is a potentiometer with an adjustable resistance value; a speed knob is arranged on the potentiometer; the rotating shaft of the speed knob is connected with the rotating shaft of the potentiometer; the power input end of the comparator is connected with the output end of the switching power supply; the inverting input end of the comparator is connected with the output end of the RC filter; the in-phase input end of the comparator is connected with a reference power supply; and the output endof the comparator is connected with the power end of a first alarm device. According to the system disclosed by the invention, the condition that the cost is greatly lost due to abnormal stop of the electromechanical device is avoided.

Description

technical field [0001] The invention relates to an electromechanical system, in particular to an alarm control system and control method for abnormal stop of stirring equipment based on electromechanical integration, belonging to the field of mechanical engineering. Background technique [0002] Mixer electromechanical equipment is widely used in drilling or oil drilling construction, in order to maintain the uniformity of drilling fluid and suspend solid particles, and conduct continuous and reliable drilling mud solid control system for drilling fluid. It is mainly used for stirring and mixing of drilling fluid to prevent the solid phase particles of drilling fluid from depositing in its tank circulation system, so that the performance of circulating drilling fluid is stable and the mixing is uniform. The existing electromechanical equipment is not equipped with an abnormal stop alarm system. In order to minimize losses, the present invention proposes an abnormal stop alar...

AI Technical Summary

Problems solved by technology

The existing electromechanical equipment is not equipped with an abnormal stop alarm system. In order to minimize losses, the present invention proposes an abnormal stop alarm control system and control method for electromechanical equipment, which can issue an alarm when the electromechanical equipment stops abnormally. After the shutdown, the mud solid phase particles are deposited around the lower blades, which can reduce the resistance moment of the sediments to the blades when starting, so as to avoid starting overload and burning out the motor, which is of great significance
