^Stratification of building architecture
The IIL characteristics of elevators as IIA aircraft chests are increasing.In such high-rise buildings, elevators are designed to function as normal vertical traffic line elevators. 1 in the fire prevention area for emergency use.
: They are often installed.For this reason, it is no exaggeration to say that normal stairs are rarely used.

By the way, in the past, when a fire broke out, the elevator operation was immediately stopped, the nearest floor was stopped, and the passengers were removed from the elevator for 1 dollar.
4 = The best thing to do was to get down and evacuate using the Makatsune stairs.Then, it was best to extinguish the fire by using only the emergency elevators inside the fire prevention area. It was considered basic.

This is because the elevator is not sufficiently drip-proof and waterproof.
Reasons such as discharge from sprinklers and fire hydrants (therefore, there is a risk of their electrical control circuits failing), and the fire and heat resistance of the power in the elevator hoistway and machine room are not sufficient, etc. 6 = Depends.Also, even if these problems have been resolved, smoke and flames may enter through the end door that opens near the floor where the fire occurred, and there is a risk that the fire may spread to other floors. If the door opens on the floor where the fire occurred, there is a risk of suffocation or death due to burns to the east passenger of elevator C.Furthermore, due to a malfunction of the landing button on the floor where the fire occurred, the elevator is closed to the floor where the fire occurred (:). Due to reasons such as danger, etc. 2.

However, in the event of a fire, it cannot be expected that the people on that floor will immediately evacuate to C2, and most of them are in elevator halls that are used on a daily basis. (There is also a simulation result that says that two people are likely to concentrate, so it is difficult to say that disaster countermeasures are sufficient. Also, if the above fire occurs, it is necessary to evacuate within 5 minutes of the number of people on the floor C. It is also known that the above-mentioned 11 degrees are made up of 11 degrees.Therefore, it is a big issue whether to enforce the above evacuation during this period (=, for example, smooth C=・The present invention has been made in consideration of these circumstances, and its purpose is to effectively control elevator operation in the event of a fire and to ensure safety that can save lives. For this reason, we are pleased to provide the pipe operation system @V stem for the elevator.

The general idea of this fire is that it is effective to evacuate people who are in the fire for about 3 to 5 minutes from the time of the fire outbreak, and that it can be effective in a short period of time at the initial stage of a fire. Considering that there is almost no damage to the elevator, it is possible to stop the elevator only at the initial stage of the fire (4 = the floor where the fire occurred and evacuation #4) (double operation system - to rescue people on the floor where the fire occurred) (2) To ensure the effective continuous use of elevators and ensure safety,
The above-mentioned objectives have been effectively achieved. Hereinafter, an embodiment of the present invention will be described with reference to the - side. Figure 1 is a schematic diagram of the inside of an elevator hoistway.

Vt, when the above-mentioned 5 minutes have passed since the time of the fire detection, the timer circuit 10 outputs (2, therefore, the elevator 2 is prohibited from stopping for all pH 142 floors except for the evacuation floor. In other words, the operation is controlled after a predetermined time has elapsed. When the conditions are met, the elevator 1 will be controlled to evacuate to the evacuated floor and stop.In addition, by turning on the monitoring switch 110 where the above condition is written as Al1, the elevator 1 will be forced to add C knee (=
Thus, according to the operation control of the elevator 2 in the event of a fire outbreak as described above, at the beginning of the fire outbreak, the elevator 2 is activated and used to evacuate people, and then Since the elevator 1 is stopped, the above-mentioned evacuation can be carried out with good safety. Moreover, since the piston operation of the elevator 2 can be stopped depending on the fire situation and a general emergency evacuation can be performed, the efficiency of evacuation of people at the initial stage i can be improved. Therefore, the present invention is not limited to the above-mentioned embodiments, and is extremely effective in terms of safe operation of the elevator 2 and safety management of the building, such as making it possible to evacuate very smoothly. For example, switching the operation control mode at the initial stage of a fire outbreak may be performed not only with the passage of time as described above, but also in response to other danger detection signals. It may also be possible to simultaneously run all the elevators 2 in a group at the same time. It is also possible to install fire alarms only on floors and floors where fire is used.The present invention can be implemented in mkt form without departing from its gist. can·
