System and method capable of automatically closing fireproof door

Abstract

The invention discloses a system and method capable of automatically closing a fireproof door. The system comprises a remote monitoring system, a communication board, a relay, a motor, a door closing device, the fireproof door, a communication network and an electromagnet. The remote control system conducts control to generate instructions through the communication board according to monitored signals and sends the instructions to the relay, and the relay controls the power-on and power-off states of the motor according to the received instructions. When the fireproof door needs to be opened, the motor controls the door closing device to open the fireproof door, and the normal-open state of the fireproof door is kept through the electromagnet. When the fireproof door needs to be closed, the remote monitoring system sends the instructions, the relay is used for disconnecting a power source, the electromagnet is powered off, and the fireproof door is closed through the door closing device. By means of the system and method capable of automatically closing the fireproof door, cost can be reduced, and potential safety hazards in the prior art are eliminated. Even when the power source is interrupted or the communication network breaks down, the system can still close the fireproof door according to the related fire protection regulation, and therefore the purposes of isolating a fire alarm area and preventing fire and smoke are achieved.

Description

technical field [0001] The invention relates to the field of fire safety applications, in particular to a system and method for automatically closing a fire door. Background technique [0002] As an important facility for fire safety, the fire door is generally open and closed when a fire occurs, which plays an important role in isolating the fire area and preventing fire and smoke. Fire safety regulations point out that fire doors must be closed under any circumstances when a fire occurs. [0003] In the prior art, the fire door control system requires a special DC power supply system to control a solenoid valve to keep the fire door in a normally open state. When a fire occurs, the remote monitoring system sends an instruction to close the fire door. [0004] The working power supply of the solenoid valve is DC, so a DC power supply system is required, and the DC power supply needs battery support. Due to the limited power of the battery, each set of batteries can only pr...
