Description

Elevator Passenger Restriction System {SYSTEM FOR LIMITING ELEVATOR PASSENGERS}

Embodiments of the present invention relate to an elevator occupant limiting system for limiting the occupants of an emergency elevator for efficient evacuation in the event of a disaster such as a fire.

As the number of high-rise buildings increases recently, descending from high floors to the ground in an emergency situation requires a lot of physical strength from evacuees and takes a lot of time, so it may be difficult to evacuate. In particular, in the case of people with reduced mobility, such as the disabled, the elderly, and patients, it is impossible to evacuate through the stairs in some cases, so they cannot rely on the evacuation for the stairs.

Accordingly, in the case of the latest high-rise buildings, evacuation is made through emergency elevators, and one or more of the elevators in high-rise buildings are designated as mandatory evacuation elevators.

Priority is given to persons with reduced mobility, such as the disabled, the elderly, and patients, when boarding emergency elevators for evacuation. However, due to the characteristics of the elevator, there is a limit weight for maximum boarding, but it is difficult to immediately know when the maximum boarding is possible because it can be confirmed through a warning sound only when the limit weight is exceeded. When boarding is performed at once, such as during evacuation, even if the last occupant gets off the vehicle due to exceeding the weight limit, it is common for re-boarding to continue in case the emergency elevator is operated, resulting in a delay. If such a delay is repeated, the evacuation by the emergency elevator is not efficiently performed, and the risk level increases because it is not possible to escape from the emergency situation.

Therefore, the need for a plan to efficiently operate the emergency elevator is emerging.

Matters described in this background art section are prepared to enhance understanding of the background of the invention, and may include matters that are not prior art already known to those skilled in the art to which this technique belongs.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The detailed descriptions that follow are provided to provide a comprehensive understanding of the methods, devices and/or systems described herein. However, this is only an example and disclosed embodiments are not limited thereto.

In describing the embodiments, if it is determined that a detailed description of related known technologies may unnecessarily obscure the gist of the disclosed embodiments, the detailed description will be omitted. In addition, terms to be described later are terms defined in consideration of functions in the disclosed embodiments, which may vary according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout this specification. Terminology used in the detailed description is only for describing the embodiments and should in no way be limiting. Unless expressly used otherwise, singular forms of expression include plural forms. In this description, expressions such as "comprising" or "comprising" are intended to indicate any characteristic, number, step, operation, element, portion or combination thereof, one or more other than those described. It should not be construed to exclude the existence or possibility of any other feature, number, step, operation, element, part or combination thereof.

FIG. 1 is a cross-sectional view showing a state in which a maximum number of passengers are boarded in the elevator 110, and FIG. 2 is a cross-sectional view showing a state in which a wheelchair and a passenger are boarded in the elevator 110.

1 and 2, the evacuation elevator 110 is necessary for efficient evacuation of personnel when evacuation using the boarding stairs is restricted in an emergency such as a fire. In particular, in the case of high-rise buildings, at least one elevator must be used as an evacuation elevator. Due to the nature of the elevator, the number and weight of passengers who can board the elevator for evacuation are limited, but it is difficult to determine whether or not the maximum number of passengers is the limited number of passengers and weight. For this reason, although the manager may restrict boarding of passengers in front of the elevator door 120, even in the case of the manager, it is difficult to accurately determine this while passengers repeatedly get on and off in an uncertain situation (for example, in an elevator with a limit weight of 500 kg). In the case where an adult with a total weight of 450 kg is on board, it is not clear whether an adult can board and getting on and off repeatedly.) Elevator operation may be delayed, which may prevent efficient evacuation

In addition, as shown in FIG. 2, when the wheelchair 20 used by the patient, the disabled, the elderly, etc. is boarded in the elevator 110, it is more difficult to determine the number of people and weight that can be boarded, so that general passengers other than the wheelchair 20 ( It is difficult to know how many people can board 10).

FIG. 3 is a diagram showing blocking facilities of an elevator passenger limiting system according to an embodiment of the present invention, and FIG. 4 is a schematic diagram showing the configuration of an elevator passenger limiting system according to an embodiment of the present invention.

3 and 4, the elevator passenger restriction system includes a weight sensing unit 130 for detecting the total weight of the current passengers 10 in the elevator 110, the number of passengers currently in the elevator 110, and a space condition. It may include a photographing unit 140 for photographing and a control unit 170 for determining whether final boarding is possible based on the total weight of current passengers, the number of current passengers, and the free space condition. Here, the photographing unit 140 may be a CCTV.

Also, a display unit 150 capable of displaying the total weight of current passengers and the number of current passengers may be included around the elevator door 120 . Through this, the total weight of the passengers currently in the elevator 110 and the current number of passengers can be known to people waiting to board.

The control unit 170 may estimate the number of possible passengers through the total weight of the current passengers and the current free space in the elevator, and determine whether the current state is the maximum number of passengers that can board the elevator 110 through this. For example, if the total weight of the current passengers is 490 kg in the elevator 110 with a limit weight of 500 kg, it is impossible to board the passengers except for infants. However, if the total weight of the current passengers is 430 kg, since one person weighing less than 70 kg can board, this is displayed on the display unit 150 and the person waiting for boarding with a weight of less than 70 kg can board. can induce

In this way, the emergency elevator 110 is operated efficiently by preventing the operating time of the elevator 110 from being delayed due to repeated boarding and disembarking of passengers due to uncertain whether or not they can board the elevator even though the maximum number of people who can board the elevator 110 is boarded. can be made

And, as shown in FIG. 3, when it is determined that boarding is no longer possible after the final boarding, a blocking facility is further installed to restrict boarding of passengers waiting to board the elevator 110 through a blocking facility. It can be. The blocking facility is a blocking wall 200 disposed in front of the elevator door 120 to block entry of the elevator 110 and a blocking door formed on a part of the blocking wall 200 to be opened and closed and closed when final boarding is performed. (210). In addition, the blocking door driver 160 connected to the control unit 170 operates the blocking door 210 to close the blocking door 210 when the control unit 170 determines that further boarding is to be blocked because the final boarding has been completed. can drive

Although not shown in the drawing, the blocking door 210 is used for boarding of general passengers 10, and a door for passing a wheelchair 20 or a bed used by patients, the disabled, and the elderly may be installed separately. The corresponding door may be opened prior to the blocking door 210 so that boarding of the patient, the disabled, and the elderly may take precedence over general passengers 10 .

Although representative embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications are possible to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention should not be limited to the described embodiments and should not be defined, and should be defined by not only the claims to be described later, but also those equivalent to these claims.
