Problems solved by technology
[0007] To sum up, the current fire door control products are still in the primary stage, and the functions are not perfect. Overcurrent or short circuit will seriously cause the paralysis of the entire fire protection system, posing a huge hidden danger to fire prevention and control
There is no one product that can take into account all the problems. The current products are only far-fetched to meet the fire regulations. The biggest problem is the low reliability.

The invention discloses a full-automatic fireproof door closer. The full-automatic fireproof door closer is characterized by mainly comprising an MPC (Model Predictive Control) fire protection controller (1), a fireproof door closer machine set (2), a rotary arm (3) and a related cable, wherein the MPC fire protection controller is connected with a smoke detector, an alarm switch and the fireproof door closer machine set through different interfaces; the fireproof door closer machine set (2) is fixed to an upper door frame (4) of a fireproof door (5) during installation; one end of the rotary arm (3) is connected with the fireproof door closer machine set (2) and controlled by the fireproof door closer machine set (2); and the other end of the rotary arm (3) is fixed to the fireproof door (5). During the operation, the fireproof door can be automatically closed after an alarm signal is received and also automatically opened after an alarm-free signal is received.
Description
technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to a fully automatic fire-proof door closer. Background technique [0002] The main function of today's building fire evacuation passage fire doors is to isolate the fire and escape when a fire alarm occurs. The fire door is opened towards the fire exit, and has an automatic recovery function. People can easily run to the fire exit from the residential area or commercial area, and the door will automatically close to prevent the entry of smoke and fire, and win more survival opportunities for escapees. . The daily management of fire doors and the emergency control in case of fire have become problems that must be solved. At present, the main technologies are as follows: [0003] 1. Electromagnetic door stopper: This device uses the electromagnetic principle. It is a new product developed and produced in recent years. It is composed of an electromagnet composed of ...
