Description

  The present invention relates to an elevator operating device and an operating method in which the operation of an elevator is suppressed to the minimum necessary energy consumption.

Conventional elevator operation methods have been devised to respond quickly and reasonably to user needs. However, now that energy conservation has become an issue all over the world due to the impact of global warming in recent years, there is a voice that energy conservation should be given priority over convenience. However, since the use of elevators is closely related to daily life, no matter how much energy is saved, it cannot be completely stopped, and the saving operation with the minimum necessary consumption is performed and this saving operation is agreed by many users. It is hoped that this will be continued for a long time.
The current elevator pays attention to the convenience of the user. For example, the elevator comes as soon as the user makes a landing call. There is also a method of starting dumping after a predetermined time on the departure floor to prevent dumpling operation, that is, operating by dispersing elevators and preventing so-called long wait of users. These rational driving methods that prevent waste are pursuing user convenience, but they are not necessarily pursuing energy conservation.

Japanese Patent Laid-Open No. 9-227033 JP 2005-200217 A

  With the above driving method, elevators can respond quickly and reasonably to meet the needs of users, but energy saving has become a global issue due to the effects of global warming. Should. However, since the use of elevators has an impact on daily life, no matter how much energy saving, it cannot be completely stopped. Therefore, it is desired that the saving operation with the minimum necessary consumption is performed and the saving operation is obtained from many users and is continued for a long time.

  The present invention has been made to solve the above-described problems. The user's usage time is investigated in advance, and the number of users waiting at the landing becomes the number of people who balance the weight of the car and the weight of the balance. By allocating elevators, the power consumption of the elevator is reduced to the minimum necessary, and the reservation user can use the reservation-free user to get to the landing so that this saving operation can be continued with the approval of the user. It is intended to provide an elevator operating device and an operating method which are adapted to respond immediately when left behind.

  The elevator operating device according to the present invention includes an elevator car, a weighing device for weighing a user in the car, a counterweight connected to the crane via a car hoist, and a hoisting machine. This is an elevator driving device that is equipped with a motor to drive, and reduces the required energy consumption from the relationship between the number of users and the energy consumption, and performs the saving operation. The personal computer that can input the elevator usage information such as floor, boarding floor, desired time, etc., connected to the personal computer via LAN, etc., and the server that counts the elevator usage information entered by the personal computer, and the operation of the elevator At the same time, it is connected to the server and reads the summary table that summarizes the elevator usage request information. It is obtained by an elevator control panel for computing the that operation plan.

  In addition, when the total weight of the car and the balance weight is unbalanced, the elevator control panel will be the least energy to carry the user in a single operation or the user will be divided into multiple operations to carry the minimum energy. The operation plan is determined after calculating whether or not.

  The elevator operation method according to the present invention includes a step of inputting elevator use request information such as the number of passengers, destination floor, boarding floor, desired time, etc. by a personal computer provided in the building, and input by the personal computer. A step of totaling the elevator use request information by the server, and a total table summarizing the elevator use request information is read, and an operation plan for minimum energy consumption in a predetermined time zone is calculated, and further predetermined. In order to be able to return to the departure floor by the final time of the time zone, the number of operations and the departure time in that time zone are determined, and the estimated elevator boarding time for each elevator use desired information is provided.

  Also, using a personal computer provided in the building, a step of inputting elevator usage desired information such as the number of passengers, destination floor, boarding floor, desired time, etc., and elevator usage desired information entered by the personal computer are tabulated by the server. Steps, reading the tabulation table that summarizes the elevator usage request information, calculating the operation plan that will be the minimum energy consumption within a predetermined time zone, and manually operating the landing button without making a PC reservation And a step of sending a message for requesting cooperation in energy-saving operation, and a step of sending a message indicating that if a leftover occurs due to manual call registration of the landing button, a message is sent back immediately to carry out the leftover corresponding operation.

  According to the present invention, since the number of users waiting in the hall after the user's usage time is investigated in advance and the weight of the car and the weight is balanced, the elevators are dispatched. As a result, it is possible to reduce the cost of the vehicle to the minimum necessary, and to immediately respond to the case where the reservation user is left at the landing due to the use of the non-reserved user, so that the saving operation can be obtained from the user and can be continued.

There are “strict” and “free” categories in the “use conditions” column. In the case of “strict”, when adjusting the “estimated boarding time” with respect to the desired time, advance adjustment is possible, but it cannot be delayed. is there. In the case of “free”, it is possible to move forward or backward. In addition, if the usage floor is a short section such as the first floor based on the contents of the “departure floor” and the “destination floor”, it is treated as usage regardless of time as in the above-mentioned “freedom”. This usage information is automatically deleted when a predetermined time elapses.

FIG. 6 shows a summary table of the elevator usage information. The tabulation table is updated each time the elevator usage information is newly input.
The total items are “number of people in the up direction on each floor” and “number of people in the down direction” expressed at 10-minute intervals. The “capacity” is 15 people, the “stop floor” is 1st to 8th floors, and the “operation time from the 1st or 8th floor” is predetermined. The space between the first floor is 10 seconds, but the breakdown is 5 seconds and door opening / closing time is 5 seconds.
The first row from the left is the elevator hall floor name. Similarly, the second and eighth rows are the operation time from the 1st and 8th floors of the up operation and down operation, respectively (about 10 seconds for the 1st floor, total 70 seconds) ). The numbers 10 to 50 in the second line from the top are 10-minute time zone (between 0 and 10 minutes), 20-minute time zone (between 10 and 20 minutes), and 30-minute time zone (20 to 30 minutes). ), 40-minute time zone (between 30 and 40 minutes), and 50-minute time zone (between 40 and 50 minutes). The For example, the number of up persons in the 10-minute time zone indicates that 4 people are used from the first floor, 2 people from the 2nd floor are 6 people in total, and 3 people on the 3rd floor are 4 people down.

  FIG. 7 is a diagram showing a specific elevator usage table. Capacity (capacity) = 15 persons and 1000 kg (1 person≈65 kg), car weight (Mo) = 550 kg, car total weight = 550 kg + number of passengers (n) * 65kg, weight weight = 1000kg, average running time = 5sec, balance number = 7 people (1000kg * 0.45 / 65), speed (V) = 150m / min (2.5m / sec), unbalance speed = 5 seconds * 9.8≈20V.

By the way, the relationship between the number of users (n) in the elevator car 6 and the amount of power consumption (W) can be expressed by the following equation (1). However, equipment efficiency and fixed loss are ignored.
Consumable energy W = Kinetic energy + Unbalance energy (1) Equation Kinetic energy is the energy that the total weight of the car including the user in FIG. For AC elevator, a * 2 since the acceleration does not regenerative operation, deceleration both 1/2 * (M + m ) * V 2 occurs. Here, M is the total car weight, m is the counterweight weight, and V is the speed.
The unbalance energy is energy generated by the attractive force applied to the weight difference between the total weight of the car and the counterweight 8.
The relationship between the number of users (n) and the energy consumption (W) under the conditions shown in FIG. 6 is theoretically expressed by the following equations (2) to (5).
・ Up operation when the total car weight M is lighter than the counterweight m (NLU) 0 <n <7
W = 1/2 * (M + m) * V ² * 2-1 / 2 * (M−m) * (20V) ²
= -80843.75 * n + 572187.5 (2) Formula: Up operation when the total weight M of the car is heavier than the weight m of the balance (FLU) 7 <n <15
W = 1/2 * (M + m) * V ² * 2 + 1/2 * (M−m) * (20V) ²
= 81656.25 * n−552812.5 (3) Formula: Down operation (NLD) when the total weight M of the car is lighter than the balance weight m 0 <n <7
W = 1/2 * (M + m) * V ² * 2 + 1/2 * (M−m) * (20V) ²
= -80843.75 * n + 572187.5 (4) Formula · Down operation (FLD) 7 <n <15 when the total car weight M is heavier than the counterweight m
W = 1/2 * (M + m) * V ² * 2-1 / 2 * (M−m) * (20V) ²
= 81656.25 * n−552812.5 (5) In the case of an AC elevator, since regenerative operation is not performed, kinetic energy will be 1/2 * (M + m) * V ² for both acceleration and deceleration. * 2 It becomes.
From the above formula, the relationship between the number of users (n) and the energy consumption (W) can be expressed as a graph as shown in FIG. 8 and a numerical table as shown in FIG. Also, in the case of up driving from the above numerical contents, if there are 11 or more simultaneous users, it is more energy saving to use 5 people and 6 people instead of carrying 11 people at a time as shown below. When the number of driving users is 11 or more, it is necessary to calculate all possible driving methods and select the driving plan that saves the most energy.
・ Energy consumption 345 (KN ・ m) for up operation of 11 people
・ (Consumed energy for 5 people driving up) + (Consumed energy for 6 people driving up) = 255 (KN · m)
・ (Energy consumption for up operation of 4 people) + (Energy consumption of up operation of 7 people) = 268 (KN · m)
Since fixed losses such as device efficiency and air resistance are ignored, there are some differences from the actual situation.
Similarly, in the case of down operation, when there are 12 or more people, it is energy saving to use 6 people and 6 people separately.
Further, FIG. 10 shows the slopes of the up and down graphs of FIG. 8 in an extreme manner. In the case of up, the slope of 7 or more is larger than 7 or less, and in the case of down, the opposite is true. When the operation is divided into two or more times as described above, the energy consumption differs depending on the distribution method.
For example, if the energy consumption 590 (KN · m) of 14 up driving is divided into 6 + 8 people, it becomes 187 (KN · m), and if it is divided into 5 + 9 people, it becomes 431 (KN · m), saving energy. It becomes.

Next, the operation of the elevator operating device will be described with reference to FIG.
FIG. 11 is an elevator operation flow showing an operation method for the control panel 4 that has read the tabulation table in the server 1 to operate with the minimum electric power. A driving method will be described along this line.
First, when the start time of the 10 minute time zone (0:00) is reached, the operation plan for the 10 minute time zone is started (step S1). Looking at the 10-minute time zone of the summary table in FIG. 6, the number of people using up operation is less than 11 people on all floors, and one operation is the minimum energy consumption, but in the case of down operation the 5th floor Since the number of users from 12 is 12, what type of driving will be the minimum energy consumption is organized in detail in the usage information (not shown) of 12 people and confirmed by a detailed table as shown in FIG.
The detailed table of FIG. 12 subdivides the usage in the 10-minute time zone from the corresponding usage information (not shown) into, for example, 2-minute intervals, and the energy consumption for one operation = 2408 (KN · m), down 5th floor Dividing 12 people into 4 minutes, which is considered to be an effective distribution for minimum energy, and comparing consumption energy = 11208 (KN · m) when driving twice, choosing to carry 10 minutes at once, 2 Give a margin of minutes (considering that the plan will change due to recalculation at the time of departure, which will be described later), so that it will return to the first floor by 8:00 seconds, two minutes before the last time of the time zone, It is planned to leave the first floor 140 seconds before 8 minutes 00 seconds, and the estimated boarding time for each elevator usage information is notified (step S2).
When the scheduled departure time (5 minutes 40 seconds) is reached, the updated elevator usage information and tabulation table will be reviewed, and if all the elevator usage information can be carried in one operation as planned (step S3), the platform for each elevator usage information The call is automatically registered and the elevator is started (step S4). Here, if elevator usage information is added and there are more than the maximum number of users, or if multiple operations result in minimum energy consumption, consider the number of operations, distribution of usage that results in minimum energy consumption, etc. The departure time and the arrival time of each elevator usage information floor are recalculated, the estimated boarding time for each elevator usage information is re-contacted, the hall call of each elevator usage information is automatically registered, and the elevator departs ( Step S5).

  Next, looking at the 20-minute time zone in FIG. 6, there are 11 or more people in up operation and 12 or more people in down operation, so FIG. 13 created based on the corresponding elevator use information (FIG. 4) When organized in the detailed table, if it is divided into 4 minutes or 6 minutes, as shown in FIG. 13, energy consumption is lower in twice operation than in one operation, so it is planned to divide in 4 minutes.

In addition, as shown in FIG. 5, the user in the 30-minute time zone has “free” as the “use condition”, and the use floor is the first or second floor, and the use time is not as desired. Well, looking at the time zone in the 40 minutes range in FIG. 6, the up operation exceeds the capacity of 15, so it is necessary to operate twice in the 40 minute time zone. We do not carry out and carry on to the 40 minutes range.
Similarly, in the 40-minute time zone, as shown in the detailed table of FIG. 14, it can be seen that the two-time operation divided by 6 minutes is the minimum energy consumption.

Embodiment 2. FIG.
FIG. 15 is a flowchart for explaining the operation of the elevator operating apparatus according to Embodiment 2 of the present invention.
A case where a person inside the building or an outside person manually operates the hall button 5 without presenting a use request (without making a reservation on the personal computer 3) will be described with reference to FIG.
If a person in the building or an outside person manually operates the landing button 5 without presenting a use request (without making a reservation on the personal computer 3) in step S11 of FIG. 15, a cooperation request for energy-saving operation by reservation system The difference between the number of people in the car 6 measured by the scale device 7 and the total number of people is confirmed and recorded (step S12). When you come to the manually registered floor and the scale device 7 detects an overload and left unloading (step S13), it sends you a message 2 to return immediately and perform a corresponding unloading operation, and all calls are gone. At that time, it reverses immediately and performs an unsupported operation (step S14). This aims to ensure continuity through consideration for people left behind at the landing in response to a request for cooperation in energy-saving operation. In addition, even if it comes to the floor registered manually by step S13, if the scale apparatus 7 does not detect overload, it will drive | operate as planned (step S15).
Even if there is no manual call registration in step S11, when the balance device 7 detects an overload and leaves an unloading (step S16), the message 1 and the message 2 are sent, and all calls are also lost. At that time, it is immediately reversed and the remaining operation is performed (step S17).
In the case of a multi-car (multi-vehicle management operation), for example, in a situation such as a 20-minute or 40-minute time zone, if two vehicles are operated in cooperation, the energy saving and the waiting time of passengers will be reduced. Get better.
