By the way, in a middle-to-low-rise building such as a shopping center where each floor is designed to have a large floor space, the inside of the building is divided into multiple compartments arranged horizontally for fire protection, and multiple elevators for general use are installed in these multiple compartments. It is often provided.
In such a building, there are many sections that are not affected by the fire when the fire breaks out, so building users can evacuate by effectively utilizing the general elevators that exist in these sections that are not affected by the fire. It is desirable that

In view of this situation, the main object of the present invention is to efficiently and safely evacuate building users in the event of a fire by effectively utilizing a general-purpose elevator existing in a section of the building that is not affected by the fire. The object is to provide an elevator control device capable of

A first characteristic configuration of the present invention is an elevator control device that controls a plurality of general-use elevators that are divided into a plurality of horizontally arranged fireproof sections in a building, and that are provided in the plurality of sections,
The plurality of compartments are partitioned so that the general elevator is installed in each of the plurality of compartments,
An operation control unit that controls the operation of the plurality of general elevators, and an information acquisition unit that acquires fire information indicating the fire situation in the building,
Based on the fire information acquired by the information acquisition unit, the operation control unit sets out-of-operation zones including a fire zone in which a fire is occurring and adjacent zones adjacent to the fire zone among the plurality of zones. and suspending the operation of the general elevator existing in the out-of-operation section so as to suspend the operation of both the general elevator existing in the fire compartment and the general elevator existing in the adjacent compartment. , executing a fire control operation control that permits the operation of the general elevator existing in the continuous operation section other than the suspension section;
The operation control unit updates the setting of the out-of-operation section based on the fire information acquired by the information acquisition unit during execution of the fire control operation control, and additionally sets the The point is that the operation of the general elevator existing in the operation suspension section is suspended.

According to this configuration, when a fire occurs, the operation control unit executes fire control operation control, and based on the fire information acquired by the information acquisition unit, includes the fire section affected by the fire. A section is set as an out-of-operation section, operation of general elevators existing in the out-of-operation section is suspended, and general-use elevators existing in a continuous operation section, which is a section other than the out-of-operation section that is not affected by the fire. can be allowed to drive Therefore, when a fire breaks out, building users can evacuate using a safe general-use elevator that exists in a section that continues to operate and is not affected by the fire.

Moreover, the operation control unit updates the setting of the out of operation section based on the fire information acquired by the information acquisition unit during the execution of the fire control operation control, and the operation out of operation section additionally set by the update. Since the operation of the elevator for general use is suspended, the operation of the elevator for general use can be suspended at any time by expanding the operation suspension section at any time in response to the expansion of the fire with the passage of time. Therefore, it is possible to appropriately select a general elevator that can be used by building users for evacuation, while maintaining a situation in which building users can evacuate using the general elevator for as long as possible.

In particular, as described above, in the fire control operation control, the operation control unit sequentially updates the operation suspension section based on the fire information. At that point, the section will be set to an outage section. Therefore, it is possible to operate the general elevators in the continuous operation section with the adjacent section (the section where the fire has not occurred yet) always positioned on the outer edge of the continuous operation section, and the building users can operate the general elevators. Therefore, it is possible to suppress a large decrease in the use safety of the general-use elevator due to sudden fire in the continuous operation section in which the general-use elevator is being used for evacuation.

In a second characteristic configuration of the present invention, the fire control operation control executes evacuation floor landing processing for stopping the operation of the plurality of general elevators in the building and landing the elevator cages on the evacuation floor. After that, the operation of the general elevator existing in the operation suspension section is maintained in a stopped state and suspended, and the operation of the general elevator existing in the operation continuing section is restored and permitted. It is in.

According to this configuration, in the fire control operation control, the operation control unit first stops the operation of not only the general elevators existing in the operation suspension section but also the general elevators existing in the operation continuing section. Evacuation floor landing processing for landing the elevator cars on the evacuation floor is executed. Then, the operation of the general elevators existing in the operation suspension section is maintained in a stopped state and suspended, and the operation of the general elevators existing in the operation continuing section is restored and permitted.

Therefore, at the early stage of the fire when the initial fire information was acquired, not only the building users using the general elevators in the out-of-operation section but also the buildings using the general-use elevators in the Users can quickly evacuate to the evacuation floor, and even if there is an error in the initial fire information (fire location, etc.), they are actually affected by the fire, such as being trapped in the elevator cage. It is possible to avoid delays in evacuating building users who are using the general elevator of the section.
