Embodiment

[0030] After the system is initialized, the compressed air intake pipe 1 on the air bag 3 is connected to the compressed air pipeline; the compressed air enters the air bag 3, and the air bag 3 is installed with a pressure sensor through the pressure sensor installation hole 2; The sensor is connected to the PLC analog channel through a shielded cable; the analog signal collected by the pressure signal is processed; based on the S7-400PLC pressure detection system, after the pressure sensor analog signal is processed, it is judged whether the compressed air is leaking in the PLC program; Whether the pressure signal is abnormal, if it is abnormal, the program will output an alarm signal to drive the alarm light on the electric cabinet to flash and the alarm bell will sound, and at the same time, the upper monitoring system will pop up an alarm message; if the system detects a compressed air leak, the equipment administrator will find it immediately and deal with it in time; The ...

Abstract

The invention discloses a dust collector compressed air leakage alarming method. The dust collector compressed air leakage alarming method comprises the following steps that S1, after system initialization, a PLC analog channel is accessed through a pressure sensor mounted on an air bag; S2, an analog signal collected by a pressure signal is processed; S3, whether the pressure signal is abnormal or not is judged in a PLC program, if yes, the program outputs an alarming signal to drive an alarming lamp on an electric cabinet to flash, the alarming bell sound is made for prompt, and meanwhile anupper monitoring system pops up alarming information; and S4, after the pressure of the air bag restores to be normal, alarming is lifted. By mounting the pressure sensor and introducing PLC and upper monitoring system control, the compressed air leakage in-time alarming function is achieved; good practicability, compatibility and universality are achieved, and the dust collector compressed air leakage alarming method is highly popularized in production practice of industrial enterprises adopting compressed air; and through actual application testing of workshops, the method is stable and reliable, and alarming is timely.

Description

technical field [0001] The invention belongs to the field of industrial automatic control, in particular to a compressed air leakage alarm method for a dust collector. Background technique [0002] Energy saving and consumption reduction is the eternal pursuit of many enterprises. The compressed air of the dust collector in the threshing and redrying workshop is often not found in time due to leakage, which leads to energy waste and does not meet the requirements of energy saving and consumption reduction. Originally, there was no effective control method for the above problems, and only manual inspection was used to check whether the compressed air leaked. A compressed air leakage alarm method for a dust collector realizes the automatic control of the compressed air leakage alarm by introducing the compressed air pressure into the PLC program to judge, and effectively avoids the situation of manual inspection missed detection and long-term air leakage.
