Abstract

PROBLEM TO BE SOLVED: To ensure the safety of passengers by passing through the nearest earthquake non-stop floor and stopping on any other floor than the earthquake non-stop floor when an elevator can stop within a prescribed period without stopping on the prescribed earthquake non-stop floor. SOLUTION: When a seismic detector C4 operates, a signal is inputted into the operation controller C1 for an elevator, and inputted into an elevator synchronous position detector C2 to compute the synchronous position of the present elevator, and the an elevator main motor C3 is controlled to start and stop the elevator. The following operation is carried out; this apparatus first discriminates whether or not the seismic detector operates, then discriminates whether or not the elevator is traveling. During traveling, the elevator stops on the nearest floor. On the other hand, during stopping, its door is closed, and operation stops. During traveling, the elevator stops on any floor other than the earthquake non-stop floor, the automatic door is closed, and operation stops. By setting the floor to which flame concentrates, such as a kitchen as the earthquake non-stop floor, it is possible to protect passengers in the elevator from a secondary disaster such as fire.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving device for an elevator having an earthquake sensing device for ensuring the safety of passengers of the elevator during an earthquake.

[0002]

2. Description of the Related Art Heretofore, in an elevator having a seismic sensing device, when an earthquake sensor operates, the elevator is generally stopped at a nearest stop floor.

[0003]

According to the prior art described above, in an elevator having a seismic sensing device, when the seismic sensor operates, the elevator is stopped at the nearest stop floor.
For this reason, the stopped floor also stops on a floor where it is difficult to evacuate easily to the outside or on a floor where a secondary disaster such as a fire is likely to occur, which may make passengers more dangerous.

[0004] It is an object of the present invention to provide an elevator operating device capable of ensuring passenger safety when an earthquake detector operates.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator having an earthquake sensing device that senses and operates a vibration of a building when an earthquake occurs. When the vehicle can be stopped within a predetermined time without stopping at the non-stop floor during an earthquake, it is achieved by passing through the nearest non-stop floor during an earthquake and stopping at a floor other than the non-stop floor during an earthquake.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a control block diagram of the present invention.
FIG. 2 is an operation flowchart of the elevator when the earthquake detector operates.

[0008] The earthquake sensing device of FIG.
Step setting is performed, and the elevator operation control device of FIG. 1C1 is a known microcomputer control device. When an earthquake occurs and the earthquake sensing device C4 operates, the signal is input to the elevator operation control device C1. Elevator operation control device C
Numeral 1 calculates the current synchronous position of the elevator based on the input from the elevator synchronous position detecting device C2, and controls the elevator main motor C3 to start and stop the elevator. The elevator operation control device C1 performs the following operation according to the flowchart of FIG. First, S1
In step 1, it is determined whether the earthquake sensing device “extra low” is operating.
If "extra low" is operating, the process proceeds to S12, and it is determined whether the earthquake sensor "low" is operating. If "low" is operating, the process proceeds to S17 to determine whether the vehicle is traveling by the elevator. If the vehicle is traveling, the process proceeds to S18 and stops at the nearest floor. It closes and the operation is suspended. If "low" is not operating, the process proceeds to S13 to determine whether the elevator is traveling. If the vehicle is traveling, the process proceeds to S14. If the nearest floor is a preset non-stop floor during an earthquake, the process proceeds to S1.
It is determined whether there is a floor other than the non-stop earthquake floor on the floor that can be stopped within 10 seconds by proceeding to 5, and if there is a floor other than the above-mentioned non-stop earthquake floor, proceed to S16 and pass through the non-stop earthquake floor, Stop on a floor other than the non-stop floor at the nearest earthquake. After stopping, S19
Then, the door is opened for 15 seconds, and the operation is stopped after the automatic door is closed. At this time, the non-stop floor at the time of the earthquake is set to a floor where fires such as a kitchen are concentrated, so that passengers of the elevator can be protected from a secondary disaster such as a fire.

As described above, according to the present invention, even if an earthquake occurs, if the vehicle can be driven to a floor other than the non-stop earthquake floor within a predetermined time, the vehicle passes through the non-stop floor during earthquake and other than the nearest non-stop floor during earthquake. By stopping on the floor, passenger safety can be ensured.

[0010]

As described above, according to the present invention, even when an earthquake occurs, the nearest floor is a predetermined non-stop floor during an earthquake, and a predetermined time is maintained even after passing through the above-mentioned non-stop floor during an earthquake. If it is possible to stop within, the passengers can be secured by passing through the non-stop floor at the time of the earthquake and stopping at the nearest floor except the non-stop floor at the time of the earthquake.
