Description

Robot Linked Elevator System {Robot Linked Elevator System}

The present invention relates to a robot-linked elevator system, and more specifically, to a robot-linked elevator system that enables the provision of high-quality robot services by calculating the expected arrival time of a robot that provides services by moving between floors through an elevator installed in a building and informing the customer of the expected arrival time.

In various buildings constructed for residential, business, or commercial purposes, elevators are installed to facilitate the smooth movement between floors of passengers entering and exiting the building. Typically, an elevator is composed of an elevator car that moves along a vertical shaft formed inside the building, a mechanical section including a motor section and a traction machine that generate power to raise and lower the elevator car, and a control section that performs control related to the operation of the elevator.

Recently, as the service of robots in buildings becomes more active, the need to use elevators to move robots between floors in buildings is increasing. For example, many service robots that move around buildings to perform tasks such as transporting items, cleaning, and guiding customers are being developed and put into practical use, and elevators are mainly used as a means of moving robots between floors that perform tasks on multiple floors.

As the robot market has grown rapidly in recent years, many service areas are being replaced by robots, and in particular, unmanned operation using robots is progressing rapidly in buildings that operate customer service businesses such as hotels and residences.

Meanwhile, 'time' is an important factor in determining service quality when providing customer service. Here, it is important to provide customers with quick service, but it is also very important to provide information about when the service will be provided. If customers do not know at all when the service will be provided, they may feel anxious and waste time unnecessarily waiting for the service that may not arrive.

In other words, in order to provide high-quality customer service, it is necessary to accurately determine when the service will be provided to the customer and inform the customer of this.

Accordingly, the present invention aims to provide a robot-linked elevator system that calculates the expected arrival time of a robot that will provide service to a customer and provides information about this to the customer when providing robot service upon the request of a customer in a building, thereby allowing the customer to enjoy more convenient and comfortable service.

The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

According to one aspect of the present invention for achieving the above object, a robot-linked elevator system can be provided, including: a robot that moves autonomously within a building and provides robot services to customers within the building; a robot system unit that controls and manages the operation of the robot; and an elevator system unit that controls and manages the operation of an elevator installed within the building and communicates with the robot; wherein the elevator system unit includes a group management unit that determines and allocates an optimal elevator among a plurality of elevators installed within the building in response to a call request from the robot; and a control unit that controls the operation of the elevator car; and characterized in that a robot designated to perform the robot service generated by the customer's request calculates and provides a time point at which the robot will provide the robot service to the customer as an 'expected arrival time'.

The above estimated time of arrival can be calculated by including a first time required for the designated robot to board the assigned elevator car from the departure floor; and a second time required for the elevator car boarded by the designated robot to arrive at the destination floor of the designated robot from its current location.

In calculating the first required time,

- If the designated robot arrives at the departure floor platform before the assigned elevator car, the time required for the assigned elevator car to move from its current location to the departure floor platform is calculated as the first required time.

- If the assigned elevator car arrives at the departure floor platform before the designated robot, the time required for the designated robot to move from its current location to the departure floor platform can be calculated as the first required time.

In calculating the second required time, the current position of the elevator car in which the designated robot is riding can be provided from a position detection device that detects the absolute position of the elevator car.

The above first required time and the above second required time can be calculated by considering traffic volume including stop schedule information that an elevator car in which the designated robot is scheduled to board or is boarding is scheduled to stop while moving from the current location to the departure floor or the destination floor.

The above stop schedule information may include the scheduled stop floor number of the elevator car on which the specified robot is scheduled to board or is currently boarding, the door opening/closing time required for stopping, the deceleration condition for stopping, and the acceleration condition for restarting after stopping.

The above estimated time of arrival may be calculated by further including a third time required for the designated robot to get off from the assigned elevator car at the destination floor and move to the customer's location.

The above first required time and the above second required time may be calculated by the military management unit, and the above third required time may be calculated by the robot system unit.

The above-mentioned expected arrival time can be calculated periodically at regular intervals and the updated information can be provided to customers using the robot service.

The above estimated time of arrival may be notified through a terminal held by a customer using the robot service or a display device installed in the room where the customer is located.

According to the present invention as described above, a customer who receives service within a building can know the expected arrival time of the service robot in advance, so there is an effect of receiving service more conveniently and comfortably.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description below.

Figure 1 is a schematic diagram of a robot-linked elevator system according to the present invention.

The purpose and technical configuration of the present invention and the detailed operation and effect thereof will be more clearly understood by the detailed description based on the drawings attached to the specification of the present invention.

The terminology used herein is only used to describe specific embodiments and is not intended to limit the present invention. For example, terms such as "consisting of" or "comprising" used herein should not be construed as necessarily including all of the various components or various steps described in the invention, but should be construed as not including some of the components or some of the steps, or may further include additional components or steps. In addition, the singular expression used herein includes the plural expression unless the context clearly indicates otherwise.

Hereinafter, the present invention will be described in detail by describing preferred embodiments of the present invention with reference to the attached drawings. The embodiments described below are provided so that those skilled in the art can easily understand the technical idea of the present invention, and should not be construed as limiting the present invention thereby, and it is obvious that the embodiments of the present invention can have various applications to those skilled in the art.

Figure 1 is a schematic diagram of a robot-linked elevator system according to the present invention. Referring to Figure 1, the robot-linked elevator system according to the present invention may be configured to include a robot system unit (10) that controls and manages the operation of a robot (Robot) that moves autonomously within a building; and an elevator system unit (20) that controls and manages the operation of an elevator installed within a building and communicates with the robot.

The robot system unit (10) and the elevator system unit (20) operate independently of each other and can communicate with each other to use the elevator when the robot needs to move between floors in a building.

The robot system unit (10) can control all robots that move autonomously within the building and communicate with each robot for this purpose. In addition, the robot system unit (10) can receive robot service requests occurring within the building and designate a robot to provide the corresponding service in response to the received request. Here, the term 'robot service' can mean a service performed by a robot and provided by the robot directly visiting the customer.

In the present invention, the robot may collectively refer to all autonomous mobile devices that can move autonomously within a building without human intervention. For example, the robot may be a service robot that carries and delivers items such as parcels within a building, or performs specific tasks such as cleaning or customer guidance, and may provide necessary services to customers within the building under the control of a robot system unit (10) built within the building.

The robot can recognize the space inside the building and move autonomously based on information collected using Lidar, proximity sensors, ultrasonic sensors, or cameras, and a simultaneous localization and mapping (SLAM) technique. In addition, the robot can store information about the internal/external structure of the building and the location of the elevator in the building through its own database, and can use the localization estimation technique to obtain the optimal distance and movement path from the current location estimated in real time to the elevator using an internal algorithm.

The robot can remotely request an elevator call. As described above, when a robot service request is received within a building, the robot system unit (10) designates a specific robot to provide the service among a number of robots operating within the building, and the designated robot can transmit a 'boarding request' signal to the elevator system unit (20) to call the elevator to move to the floor for which the service is requested (if different from the current floor).

The information included in the above 'boarding request' includes information on the departure floor where the robot is currently located and the final destination floor to which it is ultimately intended to move, and may further include information on the travel time required for the robot to arrive at the platform, the weight and volume of the robot, the purpose of using the elevator, etc. The travel time required for the robot to arrive at the platform can be calculated based on the robot's current location.

When a remote call from a robot is received, the group management department (21) of the elevator system department (20) described later determines and allocates the optimal elevator car to provide boarding service to the robot.

The elevator system unit (20) may be configured to include a group management unit (21) that performs group management of multiple elevators installed in a building; and a control unit (22) that performs control related to the operation of the elevators.

The group management unit (21) performs group control to operate multiple elevators installed in a building more efficiently. Basically, it can perform the function of determining and allocating the optimal elevator car for call requests entered through call buttons installed on each floor of the building, call requests entered through pre-registration of the passenger's destination floor in the destination selection system (DSS), and call requests entered remotely through an external system or other terminal.

For reference, a call that commands an elevator car assigned (allocated) to move to the floor where the passenger or robot is waiting in response to a call made by a passenger or robot on the platform to go to the destination floor is called a hall call, and a call that commands an elevator car that arrives in response to a hall call to move to the destination floor (destination floor) that the passenger or robot wants to go to is called a car call.

In addition, the military management department (21) determines and allocates the most efficient elevator car through correlation analysis of the traffic volume within the building and the location information of multiple available elevator cars and the robot in response to the robot's call request.

More specifically, the military management unit (21) detects status information on the space occupancy rate or boarding capacity occupied by passengers, robots, objects, etc. riding in each of the plurality of elevator cars operating in the building, extracts available elevator cars that the robot can ride based on information such as the weight and volume of the robot included in the boarding request information (call request information) received from the robot, and comprehensively considers the location and driving/door status information of the extracted available elevator cars, the hall call and car call information pre-registered in the corresponding elevator car, the location of the robot, etc. to allocate the optimal elevator car. Here, when considering the location of the robot, not only the floor location of the call request floor (departure floor) that the robot requested to ride, but also information on the time required for the robot to move from its current location to the platform can be considered.

Meanwhile, the robot-linked elevator system according to the present invention has a very important feature of providing guidance to a customer who will receive the robot service by providing information about the time at which the robot service will be provided (hereinafter referred to as “expected time of arrival”).

Specifically, the robot-linked elevator system according to the present invention can derive the 'expected arrival time' by adding the time expected to be taken for a robot to provide a service to board an assigned elevator car (hereinafter referred to as 'first required time') and the time expected to be taken for a robot boarding an assigned elevator car to arrive at a destination floor (hereinafter referred to as 'second required time'), and provide information about this to a customer.

Here, the first and second required times can be calculated by the military management unit (21), and the 'expected arrival time' information derived by adding the first and second required times can be provided to the robot and service users through the robot system unit (10).

Below, we will examine in more detail the calculation mechanism for the first and second required times by the military management department (21).

First, regarding the calculation of the first required time, the military management department (21) can calculate the expected time required from the current point in time until the robot providing the service boards the assigned elevator car at the departure floor as the first required time by referring to the elevator call request information generated by the robot, the location information of the elevator car, the pre-registered call information, the driving/door status information, etc.

Here, the expression "from the present time" is because, as described later, the military management unit (21) can continuously calculate and update the expected arrival time at regular time intervals. Therefore, the 'present time' above can mean the exact time at which the military management unit (21) calculates the 'expected arrival time' in real time. If it is after the robot has boarded the assigned elevator car, the first required time will be calculated as '0'.

Meanwhile, in calculating the first required time, the time at which the robot that called the elevator and the elevator car assigned to it arrive at the departure floor platform may be different from each other. That is, there may be a case where the robot arrives at the departure floor platform first and a case where the assigned elevator car arrives first, and therefore, in the present invention, the first required time may be calculated by dividing it into the following two cases.

First, if the robot is expected to arrive before the elevator car assigned to the departure floor platform, the military management unit (21) can calculate the time required for the assigned elevator car to arrive at the departure floor platform from its current location as the first required time.

On the other hand, if the assigned elevator car is expected to arrive at the departure platform before the robot, the group management unit (21) can calculate the time required for the robot to arrive at the departure platform from the current location as the first required time. At this time, the assigned elevator car that arrives at the platform first can be controlled to maintain the door open standby state at the platform. In addition, the current location of the robot can be estimated using the robot's self-location estimation technique as described above, and the first required time required for the robot to arrive at the departure platform from the current location can be calculated using this.

Next, regarding the calculation of the second required time, the military management department (21) can calculate the second required time as the expected time required for the elevator car to arrive at the destination floor where the robot wants to get off from the current location while the robot is on board by referring to the robot's call request information and the pre-registered call information of the elevator car allocated by the robot's call request.

The expression "from the current location" here is also because the military management department (21) can continuously calculate and update the expected arrival time at regular time intervals. In the case before the robot boards, the current location means the location of the elevator car when the elevator car arrives at the departure floor to service the hall call generated by the robot's call request, and the current location after the robot boards means the physical current location of the elevator car.

Meanwhile, the military management department (21) may consider the traffic volume (congestion situation) of the elevator car in calculating the first required time and the second required time.

More specifically, the military management unit (21) can calculate the first required time and the second required time by considering the 'stopping scheduled information' that the elevator car that the robot is scheduled to board or is currently boarding is scheduled to stop while moving from the current location to the departure floor or destination floor. At this time, the deceleration condition performed when the elevator car stops and the acceleration condition performed when starting again after the stop can be considered, and even the opening and closing time of the elevator door required when stopping can be considered in calculating the first required time and the second required time.

The total of the "elevator door opening/closing time required when stopping" above can be calculated as "the number of floors on which stops are scheduled in the middle × the elevator door opening/closing time on that floor," and the "elevator door opening/closing time" can mean the time required from the time the door of an elevator stopped on a specific floor opens until the door closes again after waiting in an open state for a predetermined period of time.

In addition, since the present invention is proposed to be applied to an elevator system in which robots can be used, an elevator car allocated by a call from a service robot in the present invention can be set to either a 'passenger car mode' in which the robot and a general passenger (human) are permitted to ride together, or a 'robot-only mode' in which only the robot can exclusively use the elevator.

Elevator cars set to the shared ride mode can be operated with two 'elevator door opening/closing times': a 'general opening/closing time' set to a short time of approximately several seconds for general passengers (humans) to get on and off, and a 'robot opening/closing time' set to a relatively long time of approximately several tens of seconds for robots to get on and off.

If a robot is scheduled to board or the elevator car that is currently boarding is set to the shared-route mode, the group management unit (21) can calculate the total of the "elevator door opening/closing time required when stopped" by adding the "number of floors scheduled to be serviced by a call from a general passenger (human) or a destination floor registration × general opening/closing time" and the "number of floors scheduled to be serviced by a call from a robot or a destination floor registration × robot opening/closing time." At this time, if there is a service floor where both a general passenger (human) and a robot are scheduled to board or disembark, duplication can be eliminated and the robot opening/closing time can be given priority.

On the other hand, an elevator car set to robot-only mode can be operated with the elevator door opening/closing time set to only one of the 'robot opening/closing times' described above. Therefore, when an elevator car that a robot is scheduled to board or is currently boarding is set to robot-only mode, the group management department (21) can calculate the total of the "elevator door opening/closing time required when stopped" as "the number of floors scheduled to be serviced (without distinction) × robot opening/closing time."

In addition, the military management department (21) may additionally include the time required for the robot to board the assigned elevator car at the departure floor and the time required for the robot to get off the elevator car at the destination floor in order to more closely predict the first required time and the second required time described above from the actual values.

More specifically, the first required time can be calculated by adding the 'robot opening/closing time' to the time expected to be taken from the present time until the assigned elevator car arrives at the departure floor platform or until the robot arrives at the departure floor platform (estimating that the robot will board within that time).

In addition, the military management department (21) can calculate the second required time by adding the 'robot opening/closing time' to the expected time required for the elevator car carrying the robot to arrive at the destination floor from the current location (estimating that the robot will disembark within that time).

In addition, the robot-linked elevator system according to the present invention can additionally add a third time required for moving from the robot's current location on the destination floor to the customer's location when calculating the 'expected time of arrival' for more accurate prediction. Here, the third time required can be calculated by the robot system unit (10) itself, and the robot system unit (10) can add the first and second times required and the third time required provided from the group management unit (21) to provide information to the customer as the 'expected time of arrival'.

In addition, the current position of the robot can be estimated by the robot using the self-position estimation technique as described above, and if the robot has not yet arrived at the destination floor (i.e., the robot is still located at the departure floor or is boarding the elevator car), the calculation of the third required time can be performed by using the platform position of the destination floor as the current position within the destination floor.

The robot-linked elevator system according to the present invention can periodically perform calculation of the 'expected arrival time' of the service robot at regular time units (e.g., 10 seconds) and transmit the calculated information to the customer periodically or upon request.

Accordingly, even if a new call or destination floor is input during a series of processes in which an elevator is allocated by a call from a service robot, the robot boards the allocated elevator, and moves to the destination floor, the present invention makes it possible to continuously update and provide information on the 'expected arrival time' of the service robot to the customer.

The 'estimated time of arrival' of the service robot calculated through the above mechanism can be guided through a terminal held by the customer who will receive the service or a display device installed in the room where the customer is located. In this case, guidance can also be provided through other devices such as a voice guidance device, but in order to provide continuously updated time information, a display device capable of visual display may be more preferably used, and when using a display device, it may be possible to express it in a way that the time remaining until the estimated time of arrival decreases.

Meanwhile, the control unit (22) controls the overall operation and behavior of the elevator, and can perform control to move the elevator car assigned by the military management unit (21) to the floor where the call was entered.

The control unit (22) may include a driving control unit that controls the driving operation of the elevator car, a door control unit that controls the opening and closing of an elevator door that stops at a specific floor for boarding and disembarking passengers and robots, etc.

The driving control unit can control the operation of raising and lowering an elevator car within a hoistway formed vertically inside a building, and can perform driving control of a winding machine motor and brake, etc., to start or stop the operation of the elevator car by a specific command signal.

The door control unit controls the overall opening and closing operation of the elevator doors, including the hall door installed on the platform side and the car door installed on the elevator car side, and can control the operation of the door motor for this purpose.

Below, the overall procedure from the occurrence of a request for robot service within a building to the completion of service provision to a customer receiving the robot service in a building to which the robot-linked elevator system according to the present invention is applied will be examined in detail in a sequential manner.

First, when a robot service request is received by a customer within the building, the robot system unit (10) specifies a robot among multiple robots within the building to perform the service.

The designated robot moves to the destination to perform the service. When the floor where the destination is located is different from the floor where the robot is currently located, the robot must use an elevator to move between floors. To do this, the robot can remotely call an elevator directly through the elevator system unit (20).

When an elevator call request by a robot is received, the group management department (21) of the elevator system department (20) determines and allocates the optimal elevator car to provide boarding service to the robot.

And, at the same time as the optimal elevator car is allocated, the robot-linked elevator system according to the present invention can calculate and provide information on the 'expected arrival time' of the service robot to the customer receiving the service.

Here, the 'estimated time of arrival' can be calculated by adding the first estimated time it is expected to take for the service robot to board the elevator car, the second estimated time it is expected to take for the robot boarding the assigned elevator car to arrive at the destination floor, and, if necessary, the sum of the third estimated time it is expected to take for the robot to get off the elevator car and arrive at the destination (customer's location) can also be considered.

Below, a method for calculating the 'estimated time of arrival' for each time point is specifically explained, using as examples the time point before the robot boards the assigned elevator car (time point 1), the time point while the robot is boarding the assigned elevator car (time point 2), and the time point after the robot gets off the elevator car at the destination floor (time point 3).

First, regarding the calculation of the expected arrival time at the first point in time, the group management unit (21) calculates the first required time based on whether the robot arrives at the departure floor platform first or the assigned elevator car arrives first. Then, the group management unit (21) sets the current location of the elevator car in which the robot boards the robot as the departure floor and calculates the time required to move to the destination floor as the second required time. The first point in time is a state in which the robot has not actually boarded the elevator car, but assuming that it has boarded, the expected time required to move from the departure floor to the destination floor is calculated. Similarly, the third required time can be calculated by assuming that the robot has gotten off at the destination floor. In this case, the robot system unit (10) can perform the calculation of the third required time by setting the location of the platform on the destination floor as the current location within the destination floor.

The robot system unit (10) can add up the first and second required times transmitted from the military management unit (21) and, if necessary, add up the third required time calculated by itself to generate final information indicating the 'expected arrival time' and provide this to the customer.

Next, regarding the calculation of the expected arrival time at the second point in time, since the second point in time is after the robot has boarded the assigned elevator car, the first required time is calculated as '0'. The military management unit (21) calculates in real time the time required for the elevator car in which the robot has boarded to arrive at the destination floor from the current location. Here, information on the current location of the elevator car can be provided from a position detection device (not shown) that detects the absolute location of the elevator car, and the second required time required to arrive at the destination floor can be calculated by considering the speed of the elevator car, acceleration/deceleration, and traffic volume of the elevator car. The third required time can be calculated in the same way as at the first point in time.

Lastly, regarding the calculation of the expected time of arrival at the third point in time, at the third point in time, both the first required time and the second required time will be calculated as '0', and only the third required time, which is expected to be required to move from the current location estimated through the robot's self-location estimation technique to the location of the service user, can be calculated and provided as the expected time of arrival.

If the calculation of the estimated time of arrival does not take into account the addition of a third time, it would be possible to provide a message to the service user such as "The service robot has arrived at the destination floor and is moving to the customer."

As described above, the robot-linked elevator system according to the present invention can provide information on the time at which the robot service will be provided, i.e., the 'expected time of arrival', to a customer who will receive the robot service, and thus has the effect of providing a more convenient and comfortable high-quality service to the customer using the robot service.

The robot-linked elevator system according to the present invention described above may include at least one processor implemented to execute computer-readable commands. In addition, the present invention may be implemented as computer-readable codes on a computer-readable recording medium. The computer-readable recording medium includes all kinds of recording devices that store data that can be read by a computer system, such as ROM, RAM, CD-ROM, magnetic tape, floppy disk, and optical data storage devices.

The present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should fall within the scope of the claims of the present invention.
