Description

Self-driving control method of elevator

The present invention relates to an elevator, and more particularly, to a self-controlling operation method of an elevator capable of evacuating passengers in an elevator and making an emergency operation by using a self-generator in a building during a power failure.

The elevator used as a means of passenger transportation in a building is also important for its speed, but stability is very important because it is directly related to the passenger's life. Therefore, when an emergency such as a power failure occurs, it is necessary to operate the elevator safely and efficiently.

1 is a view showing a conventional elevator driving system. The elevator operating system in the building may be operated by several elevators according to the number of floors or the number of floors of the building, but in the drawings will be described limited to four elevators for convenience of description. As shown in the drawings, a conventional elevator operating system includes a first unit 1, a second unit 2, a third unit 3, and a fourth unit 4 elevators, and a machine room for operating the elevators ( 5) and a monitoring panel 11 for monitoring the state of the elevator.

In the machine room 11, the self-generator 6 which operates an elevator, the 1st unit control panel 7, the 2nd unit control panel 8, the 3rd unit control panel 9, and the 4th unit control panel which control each elevator ( 10), the monitoring panel 11, the first unit self-initiation and continuation switch (15), the second unit self-initiation and the like to control each elevator to the evacuation floor and emergency operation during self-control control operation And the first switch, which selects manual operation and automatic operation during the continuous switch 14, the third foot presser foot return and the continuous switch 13, the fourth foot presser foot return and the continuous switch 12, and the self-control control operation. It consists of a wig manual and automatic switch 19, the second and second foot wig manual and automatic switch 18, the third and the third foot wig manual and automatic switch 17, the fourth and fourth foot wig manual and automatic switch 16 .

The self-initiating and continuing switches 12, 13, 14, and 15 are three-stage switches in which the home operation switch is a contact point, the continuous operation switch is b contact point, and the normal operation switch is c contact point. (16, 17, 18, 19) are two-stage switches with an automatic switch at contact a and a manual switch at contact b.

Hereinafter, with reference to Figures 1 and 2 will be described in detail the conventional elevator self-driving control operation.

As shown in the figure, when the power failure occurs during normal operation, all the elevators 1, 2, 3, 4 stop. At this time, when the self-power generation is not made by the self-generator, the elevators 1, 2, 3, and 4 remain in a stopped state, but when self-power is generated, the self-foot control operation starts.

In the case of the manual operation method in which the manual operation switch (contact point b) is operated in the manual and automatic switches 16, 17, 18, and 19, the autonomous foot corresponding to each elevator (1, 2, 3, 4) and The return operation switch (contact point a) is operated by the continuous switches 12, 13, 14, and 15 to select any one of the four elevators 1, 2, 3, and 4 to return to the evacuation floor. . When the selected elevator stops on the evacuation floor, the elevator door is opened to evacuate the passengers and the lights in the elevator are turned off. After 15 seconds have elapsed, the door remains closed for a certain period of time, and then the door is opened again in the above standby state by operating the open button for the passenger who has not got off. Then, when the next elevator arrives at the evacuation floor, the above process is repeated to safely evacuate the passengers to the evacuation floor.

At this time, if the elevator (1, 2, 3, 4) is an automatic operation method in which the automatic operation switch (contact a) is operated, regardless of the self-resulting and the continuous switch (12, 13, 14, 15) in a predetermined order After the elevators 1, 2, 3, and 4 return to the evacuation floor one by one, the passengers are evacuated safely by repeating the same procedure as in the manual driving method.

After that, in the case of manual operation mode, operate the continuous operation switch (contact point b) of the autonomous foot return and the continuation switch (16, 17, 18, 19), and select any one elevator for emergency operation. Stop the running elevator once and switch all the elevators to normal operation. In addition, in the case of the automatic operation method, the predetermined elevator makes emergency operation regardless of the self-initiation and the continuous switches 16, 17, 18, and 19.

However, in the conventional elevator operating system as described above, when the power is out of power, any one elevator is returned to the evacuation floor to evacuate the passengers, and the same operation is repeated for the other elevators in order to finally return to the evacuation floor. Since it takes a long time to return the passengers of the elevator to the evacuation floor, there is a problem that anxiety increases. Moreover, since all the elevators are returned to the evacuation floor and the emergency operation is performed by self-balancing, the time required for the emergency operation becomes long, so that efficient operation becomes difficult.

Accordingly, the present invention is to solve the above problems and to provide a self-controlling driving method of the elevator that can solve the anxiety of the passengers by evacuating the passengers in advance by first operating each elevator from the emergency stop floor to the lowest floor during power failure. For the purpose of

Another object of the present invention is to evacuate the passengers to the bottom floor and return the elevator located at the furthest distance from the evacuation floor to the evacuation floor while performing the calling service, and the returned elevator performs emergency operation for the passenger. It is to provide a self-controlling operation method of the elevator that can reduce the service time and efficient operation.

In order to achieve the above object, the elevator self-foot control operation method according to the present invention after the self-power generation by the self-generator in case of power failure to operate a plurality of elevators in turn by operating a return operation switch of the self-resulting and continuing switch Evacuating the passengers to the lowest floor of each elevator, driving to the evacuation floor while calling the elevator farthest from the evacuation floor, and emergencyly operating the elevator returned to the evacuation floor. do.

An elevator that arrives at the evacuation floor and disengages passengers during the call service, opens the door again after a certain time after the door is closed, and completely unloads the passenger who failed to get off. When the power supply is restored, all the elevators are operated normally again after the elevators which have been in emergency operation have stopped.

If the elevator is in manual operation mode, evacuate passengers to the lowest floor by operating each elevator by operating the self-resulting and continual switches installed in the monitoring station.In case of elevator automatic operation mode, elevators are automatically entered in a predetermined order. Evacuate passengers to the floor.

In this case, only four elevators will be described for convenience of description as described in the conventional elevator self-control control operation method.

As shown in the figure, when a power failure occurs during normal normal operation of the elevators 1, 2, 3, 4, all the elevators 1, 2, 3, 4, 5 are stopped. Elevators 1, 2, 3, and 4 remain stationary when self-power generation is not performed by the self-generator 6 installed in the machine room 5, but when self-power generation occurs, the self-foot control operation starts. do.

If the manual switch (b contact) of the self-passing manual and automatic switches 16, 17, 18, and 19 in the control panel 11 is operated manually, the self-corresponding person corresponding to each elevator (1, 2, 3, 4) By operating the return operation switch (contact a) of the foot return and continue switches 12, 13, 14, and 15, the elevators 1, 2, 3, and 4 are operated in turn to the nearest floor, which is the nearest floor, and then stopped. Then, open the doors of the elevators 1, 2, 3, 4, evacuate all the passengers, turn off the lights of the elevators, close the doors, and open the door again after 15 seconds in case the passengers do not get off. This state is maintained for a certain period of time.

If the auto switch (contact point b) of the self-automatic and manual switches 12, 13, 14, and 15 is operated, the elevators 1, 2, 3, and 4 are autonomous and the continuous switch 12, Irrespective of the return operation switch (a contact) of 13, 14, and 15), the passengers are evacuated to the top floor one by one in a predetermined order automatically.

Then, in the manual operation mode, the self-resulting of the elevator 12 located farthest from the evacuation floor and the continuous operation switch (contact point b) of the continuation switch 14 are operated so that the above-mentioned elevator 2 Return to the evacuation floor with a calling service. At this time, when the elevator 2 of the uppermost floor becomes inoperable, the elevator 3 of the uppermost floor of the elevators 1, 3, and 4 except for the elevator 2 is operated to return to the evacuation floor. When the return to the evacuation floor is completed, the above-mentioned elevator (2) is made an emergency operation again, when the power is returned, once the elevator (2) is stopped, the self-resulting and continuing switches (12, 13, 14, Operate the normal operation switch (contact point c) of 15) to switch all elevators (1, 2, 3, 4) to normal operation.

In addition, in case of automatic driving method, the elevator located at the longest distance to the evacuation floor is automatically selected regardless of self-involving and continuous switches (12, 13, 14, 15) and returns to the evacuation floor after the call service. Emergency operation.

Since the elevator self-control driving method according to the present invention evacuates each elevator to the nearest floor as described above, passengers are compared to the conventional self-control driving method in which all elevators operate to return to the evacuation floor. The time spent in an elevator during a power outage is shortened. Thus, the anxiety of the passengers is greatly reduced. In addition, since the passengers who boarded each elevator were evacuated to the lowest floor of each elevator, the elevator that operates the longest distance from the evacuation floor was returned to the evacuation floor while performing the calling service, thus enabling efficient operation of the elevator. .
