High-recognition safe type centrifugal fan intelligent control system

Abstract

The invention discloses a high-recognition safe type centrifugal fan intelligent control system. The high-recognition safe type centrifugal fan intelligent control system comprises a centrifugal fan, a frequency converter connected with the centrifugal fan, a programmable controller connected with the frequency converter, a display and control touch screen, a temperature monitoring structure, a pressure monitoring structure and a remote alarm structure, wherein the display and control touch screen, the temperature monitoring structure, the pressure monitoring structure and the remote alarm structure are connected to the programmable controller. A power supply is further connected to the programmable controller and the frequency converter at the same time. The remote alarm structure comprises a signal emitter connected to the programmable controller, a signal receiving circuit connected with the signal emitter through a wireless network, a remote alarm connected to the signal receiving circuit, and a storage battery connected with the remote alarm and supplying power to the remote alarm. By means of the high-recognition safe type centrifugal fan intelligent control system, the system use safety is greatly improved, the product energy consumption is lowered, products are simplified, and meanwhile the use effect of the products is improved.

Description

technical field [0001] The invention belongs to the field of centrifugal fan use safety, and specifically refers to an intelligent control system for a centrifugal fan with high recognition safety. Background technique [0002] In recent years, programmable logic controllers have been widely used due to their many excellent features, and have become standard equipment for industrial control in industrially advanced countries. It is specially designed for industrial control, integrating electrical, instrumentation and control, and is an ideal control device for realizing mechatronics. [0003] Conventional centrifugal blowers, referred to as centrifugal fans, mostly use traditional relay control circuits in their control systems, and a large number of intermediate relays and time relays are used in traditional blower relay control circuits. Failure and accidents are prone to occur due to poor contacts. Due to the extensive use of traditional relays, the control system is bl...

AI Technical Summary

Problems solved by technology

In a relatively harsh and dangerous gas environment, the safety factor is low, and it is likely to cause sudden accidents due to ignition of the traditional contactor contacts during operation

[0006] However, the traditional centrifugal fan cannot realize remote alarm, and the staff cannot know whether there is a problem when the product is running, so that it cannot solve the problem when the product is used immediately, which greatly increases the risk of product use.
