BRIEF DESCRIPTION OF THE DRAWINGS The system block diagram of the elevator which is Embodiment 1 of this invention, and FIG. 2 is a flowchart explaining the operation | movement of the elevator control apparatus which is Embodiment 1 of this invention.

In FIG. 1, 1 is an elevator control panel, and the elevator control panel 1 performs the operation management of an elevator, speed control, etc. collectively.

In the first embodiment, the elevator control panel 1 includes the getting off means 11 before the tank drainage operation, the ground fault information 12, the destination button information 13, the water level detection information 14, the display / information means 15 and The traveling command means 16 to the layer immediately before the lowermost layer 5 is provided.

In addition, 2 is a car operating part (operating panel), 3 is a destination button, and 4 is a door opening / closing button.

As described above, the discharging means 11 before the tank drainage operation is performed in order to prevent the passengers from being trapped during the tank drainage operation, when the lowermost floor 5 is the irregular floor. The information is obtained and the up run is commanded as follows.

That is, when the water in the drain tank (not shown) reaches a predetermined level and performs the drainage operation in the drain tank, the passenger car is stopped by stopping the car on the floor just before the lowermost floor 5.

Thereafter, it is considered that a passenger who travels to the lowest floor 5 to start the tank drainage operation but fails to get off.

For this reason, only when any button of the car operating part 2 was operated by the passenger who failed to get off before the tank drainage operation started, the car which stopped on the lowermost floor 5 again has the closest stop floor. Command up run toward.

After the up-traveling starts, the information of the traffic floor information 12 and the destination button information 13 is obtained, and if the destination button operation floor is not the traffic floor, normal car call registration is performed, and the destination button operation floor is the traffic floor. The rear display and notification means 15 is instructed to output "No call registration to the operation floor." And the car call registration is performed on the floor which is not the nearest illegal floor.

In the meantime, when the vehicle is traveling while giving a notice and display of the refusal to ride, and the destination button 3 is newly operated, when the destination button 3 is completed again in response to the final car call, the door is opened at the floor. It closes and issues a run command to the lowest floor 5, the car is stopped to the lowest floor 5, and the water in a drain tank is drained.

If the destination button 3 is not operated within a predetermined time after the start of the up run, the vehicle stops at the closest stop floor (normally, the stop floor just before the lowest floor), and closes the door after a predetermined time. The driving to the lowermost floor 5 is instructed, the car is stopped at the lowermost floor 5, and the water in the drain tank is drained.

Next, the operation of draining the water in the drain tank will be described based on the flowchart of FIG. 2.

In FIG. 2, when the car operating part (operation panel) is operated before draining the water in a drain tank in the lowest floor which is a tank drainage layer, the following operation | movement is performed in order to lower a passenger.

Step S1: During the cooler operation, the tank drainage layer (lowest floor) is operated as an unclear floor (normal operation mode).

Step S2: When the water level in the tank is a predetermined level, for example, 80% is detected, the flow advances to step S3. Otherwise, normal operation is continued (step S1).

Step S3: Stop the operation of the cooler and prohibit the response to the platform call. (Tank drain operation mode)

Step S4: If the door is completely closed in response to the final car call, proceed to step S5, and if there is a car call registration to be answered, go to step S3.

Step S5: Drive toward the floor immediately preceding the lowermost floor and stop.

Step S6: It is determined whether any button of the car operating part (operating panel) 2 has been operated until the car starts traveling toward the lower floor from the floor immediately preceding the lower floor, and if not, proceeds to step S7. If there is operation of any button of the car operating part (operation panel) 2, it progresses to step S10.

Step S7: Run toward the lowest floor of the tank drainage layer, and determine in step S8 until the tank drainage operation starts.

Step S8: It is determined whether any button of the car operating part (operation panel) 2 has been operated until the car performs the tank drainage operation, and if it is not operated, the process proceeds to step S9, and if there is an operation of any one button of the operation panel. Proceed to step S14.

Step S9: Drain the water in the tank.

Step S10: If the destination button is operated, the flow advances to step S11, and if not, the flow returns to step S6.

Step S14: If the destination button is operated, the flow advances to step S11, and if not, the flow goes to step S5.

Step S11: It is determined whether the operation of the destination button is the wrong floor, and if not, the flow advances to step S12.

Step S12: The car call registration of the operation floor is performed as usual.

Step S13: Since the car call registration is impossible on the illegal floor, the car call registration is performed on the floor (stop floor) which is not the nearest illegal floor, and the car call registration is notified to the operation floor.

Step S15: Answer only the registered car call and proceed to step S7 after the response is completed.

Next, the modification of Embodiment 1 is demonstrated.

In this case, in order to get off the remaining passengers in the car, the nearest floor or the destination button 3 was directed to the operated floor. However, in this modified example, the car is once the highest floor while the boarding is notified and displayed. The vehicle may then travel on the lowermost floor, and then stop on the floor immediately preceding the lowermost floor, and then travel on the lower floor 5.

In this way, passengers who remain in the car while getting on and off can finally operate the destination button 3 of the intended floor, so that all the passengers can get off at the intended floor, so that they can be prevented from being trapped more reliably. have.
