AI Technical Summary

Technical Problem

It is difficult for existing fan control devices to effectively switch the speed of firefighters and ordinary fans in normal production and fire emergency situations, resulting in waste of energy or poor fan effect in emergencies, affecting the safety of the production site.

Method used

Design a fire-fighting dual-speed fan control device, including a control housing and an integrated circuit, using components such as microprocessor, communication module, relay control output circuit, alarm output circuit and indicator light, and realizes by receiving remote control signals and manual control buttons. The fan is remote and manual start-stop, and the fan speed is controlled by different voltage values. Interlock circuits and voltage clamp protection circuits are set to ensure speed switching.

Benefits of technology

It realizes flexible speed control of the fan in different situations, avoids energy waste, ensures effective fan operation in fire emergencies, improves the safety of the production site and the multi-functional remote control effect of dual fans.

Abstract

This invention discloses a fire-fighting dual-speed fan control device. The device includes a control housing and a control integrated circuit. The control integrated circuit, housed within the control housing, receives control signals from a remote control terminal and the control device to control both the fire-fighting fan and a regular fan. This invention achieves different speeds for the fire-fighting and regular fans under different conditions by connecting different voltage values ​​(fire-fighting voltage and regular voltage) to the input terminals. The control panel of the dual-speed fan control device includes control buttons for selecting the operating status of the two fans and indicator lights displaying their operating status, enabling one device to control the operation of the two fans at different speeds. Simultaneously, by providing a control signal input terminal connected to a remote control terminal, remote control of the two fans at different speeds can be achieved by receiving remote control signals sent from the remote control terminal.
