BACKGROUND OF THE INVENTION
The present invention relates to an elevator control method and control apparatus that perform two-car control.
[0002]
[Prior art]
In general, a two-car control device that controls two elevators selects the elevator car of the most suitable for handling the hall call from the two elevators when a hall call occurs on a certain floor. In response to the landing call generation floor.
[0003]
In a two-car control device, when selecting a car, if both cars are non-directional, one is non-directional, the other is directional, two are directional, and so on. The car is selected by applying a rule for each mode determined in advance, such as mode 1, mode 2, and mode 3, respectively.
[0004]
Here, the car selection method in the mode 2 will be described with reference to FIG. Assume that the 8th floor down hall call 22 is generated while the No. 1 machine 23 is moving up toward the car call 21 on the 7th floor and the No. 2 machine 24 is stopped in a non-directional direction on the 1st floor.
[0005]
There are a plurality of rules for each mode, priorities are set among these rules, and the corresponding machines are selected in order from the rule with the highest priority.
[0006]
The first rule in the case of mode 2 is “The call to the stop floor of the non-directional unit responds to the non-directional unit”. Therefore, it is first determined whether or not the first rule can be applied. In the situation shown in FIG. 6, there is no corresponding car. Next, the second rule is that the directional car responds within a certain floor in front of the directional car. Judge whether “Yes” is applicable.
[0007]
Here, if the fixed floor is normally the second floor, it does not apply to this second rule, so the third rule "Non-directional unit if it is within a fixed upper and lower floor of a non-directional unit" can be applied. To do. This fixed floor is also usually the second floor. Therefore, since it does not apply to the third rule, the fourth rule “the directional car if the arrival time of the directional car is within a predetermined time” is determined.
[0008]
This fixed time is determined according to the number of floors of the building, and is 10 seconds in the case of FIG. Here, if the estimated arrival time until Unit 1 arrives at the hall call on the 8th floor is calculated, it is 18 seconds. Therefore, the fourth rule does not apply to the situation of FIG. Then, the 5th rule "The other hall call is a non-direction number machine" is applied, and the No. 2 machine 24 will share. As a result, the No. 2 machine 24 that has stopped until then starts to rise toward the down hall call 22 on the eighth floor.
[0009]
However, in the situation of FIG. 6, before the No. 2 machine 24 arrives on the 8th floor, the No. 1 machine 23 arrives at the 7th floor and responds to the call and stops in a non-directional direction, resulting in the situation shown in FIG. In this case, if the waiting customer waiting at the landing on the 8th floor confirms the position of the car by looking at the indicator on the landing floor, the waiting car 23 is on the way as if it was rising toward the 8th floor. At this point, the car stops and becomes non-directional, and it seems that the car 24 of another car that is far away is going to the 8th floor, which makes it uncomfortable.
[0010]
There is also a control method in which the first machine 23 is directed to the 8th floor when the first machine 23 becomes non-directional, but if the response sharing is changed to the first machine 23, the second machine 24 goes to the 8th floor. Because it is already rising and has no other call, it will stop at the nearest floor when the response sharing is changed. If this happens, the rise of Unit 2 24 will be a wasteful operation, and it may be perceived by the user as a mysterious phenomenon that the elevator suddenly rises and stops without a call, leading to another claim.
[0011]
If the fixed time in the above-mentioned fifth rule is increased to 20 seconds, for example, and the response sharing of the directional car is increased, the first machine 23 responds to the down hall call 22 on the eighth floor in the case of FIG. Therefore, the claim in this case is resolved. However, this time only one vehicle moves well and the other one does not move very much, which may lead to a claim that it cannot be operated more efficiently.
[0012]
Therefore, let us consider a case where the fifth rule is changed so that it is assigned to units that are close in position. Due to this rule change, the first machine 23 responds in the situation of FIG. 6, so that the passengers waiting on the 8th floor will not be uncomfortable. Moreover, since there is not much difference in the predicted arrival time between the No. 1 machine 23 and the No. 2 machine 24, the waiting time hardly changes regardless of which No. machine is responded.
[0013]
However, consider the case where the above-mentioned modified fifth rule is applied to the control of a two-car elevator installed in a relatively high floor building as shown in FIG. The following inconveniences occur.
[0014]
In the situation where car calls 41 on the 9th and 11th floors are registered in Unit 1 43 and are rising on the 6th floor, and Unit 2 44 is stopped in a non-directional direction on the 2nd floor, the 15th floor down hall call Suppose that occurs. First, in the first rule in the case of mode 2, it is determined whether or not “call of the stop floor of a non-directional unit responds to a non-directional unit” is applicable, but since there is no corresponding unit, the second The rule determines that “the directional unit responds within a certain floor in front of the directional unit”.
[0015]
Here again, if the fixed floor is the second floor, this second rule is not applied, so it is next determined whether or not the third rule "Non-directional car if it is within a fixed floor above and below the non-directional car" can be applied. . If the fixed floor is the second floor as in the situation of FIG. 6, this third rule is not applicable. Then, next, it is determined whether or not the fourth rule “the directional car if the arrival time of the directional car is within a certain time” can be applied. This fixed time is determined according to the number of floors of the building, and is 20 seconds in the case of FIG.
[0016]
Here, calculating the estimated arrival time until Unit 1 43 arrives at the hall call on the 15th floor is 34 seconds, which does not apply to the fourth rule, so the fifth rule “positionally” Make a decision to share with the nearest unit. In this case, according to the changed rules, the first machine 43 located close to the 15th floor will go to the 15th floor, but since the car call 41 on the 9th and 11th floors is registered in the first machine 43, take time.
[0017]
In such a situation, a passenger waiting on the 15th floor sees that the car No. 2 on the 15th floor does not respond easily, but the other machine, Unit 2 44, has stopped moving at all. , I feel uncomfortable with the elevator that is not efficient and does not come easily.
[0018]
[Problems to be solved by the invention]
Thus, in the conventional two-car control elevator control system, when one platform stops in a non-directional direction and the other one operates in a directional direction, Even if the elevator of the unit on the floor close to the call is made to respond, or conversely, the elevator of the unit with a short estimated arrival time is responded, the number of floors of the building where the elevator is installed is inconvenient to the customer. There was a problem that sometimes gave a pleasant response.
[0019]
It is an object of the present invention to provide an elevator control method and a control device with good responsiveness that do not cause discomfort to passengers waiting at a landing, whether in a two-car system with a low floor or a two-car system with a high floor. Objective.
[0020]
[Means for Solving the Problems]
According to the first aspect of the present invention, two elevator cars that serve a plurality of floors are installed, and an elevator control that responds to the optimum one of the two cars to a common hall call generated from the hall When the number of stop floors of a building is less than a predetermined value when a new landing call occurs in a situation where one is stopped in a non-directional direction and the other is operating in a directed direction by applying the rules based on the travel distance, the landing call is response to car Unit travel distance shorter until occurrence floor, the when the stop number bed is larger than a predetermined value based on the travel time The car of the car with the shorter predicted traveling time until arrival at the landing call generation floor is responded.
[0021]
In the elevator control method according to the first aspect of the present invention, a rule for determining a response assignment machine when a landing call is newly generated in a situation where one is stopped in a non-directional direction and the other one is operating in a directed direction. Apply in descending order of priority. There are two rules: one based on the distance traveled by the elevator and the other based on the travel time. Depending on the number of floors in the building where the elevator is installed, if the number of stop floors is less than the specified value, the rule is based on the travel distance. by applying the rule, then the response of the car Unit travel distance shorter until landing call occurrence floor, apply rules stop floor number floor based on the travel time when more than a predetermined value, the landing Let the car in the car with the shorter estimated travel time to reach the call generation floor respond. As a result, it is possible to determine the optimum car and respond to the hall call, and to prevent the passenger who made the hall call from feeling uncomfortable.
[0022]
The invention of claim 2 has two elevator cars that serve a plurality of floors, and controls a single control unit that controls the elevators of each unit and a common hall call generated from the hall. An elevator control device having a two-car control unit that responds to the most suitable car among the cars, wherein the two-car control unit stops in one direction and the other one operates in a direction. If the number of stop floors of a building is less than the predetermined value when a new landing call occurs, apply the rule based on the travel distance, and the shorter the travel distance to the landing call generation floor is the response of Unit car, the stop floor number bed applies the rules based on the travel time when more than a predetermined value, the estimated travel time is shorter Unit until arriving at the landing call occurrence floor To respond to the basket .
[0023]
In the elevator control apparatus according to the second aspect of the present invention, the control method according to the first aspect of the invention is used, and the two-car control unit is stopped in one direction and the other one is operating in a direction. When a new hall call is generated at, the rules for determining the response assignment machine are applied in descending order of priority. There are two rules: one based on the distance traveled by the elevator and the other based on the travel time. Depending on the number of floors in the building where the elevator is installed, if the number of stop floors is less than the specified value, the rule is based on the travel distance. by applying the rule, then the response of the car Unit travel distance shorter until landing call occurrence floor, apply rules stop floor number floor based on the travel time when more than a predetermined value, the landing Let the car in the car with the shorter estimated travel time to reach the call generation floor respond. As a result, it is possible to determine the optimum car and respond to the hall call, and to prevent the passenger who made the hall call from feeling uncomfortable.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block configuration diagram of an elevator control device according to a first embodiment of the present invention. The elevator control devices 1a and 1b are parts that control the operation of the elevator, and are provided with two-car control units 2a and 2b and operation control units 3a and 3b, respectively. The elevator car 4a of the No. 1 elevator is connected to the elevator control device 1a, and the operation controller 3a controls the raising / lowering operation and the door opening / closing operation of the No. 1 car 4a. On the other hand, the car 4b of the No. 2 elevator is connected to the elevator control device 1b, and the operation controller 3b controls the raising / lowering operation and the door opening / closing operation of the No. 2 car 4b.
[0025]
The two-car control units 2a and 2b are connected to the two-car transmission line 10. Normally, the two-car control unit 2a of the first unit is the master two-car control unit, and the two-car control unit 2b of the second unit is the two slave units. It is determined as one control unit.
[0026]
The hall call registration devices 9a to 9n are arranged on each floor. The hall call signals of the hall call registration devices 9a to 9n are input to the two-car control unit 2a via the hall call input / output control units 7a to 7n and further via the operation control unit 3a of the first car. At the same time, the hall call signals of the hall call registration devices 9a to 9n are input to the 2-car control unit 2b via the hall call input / output control units 8a to 8n and further via the operation control unit 3b of the second car. The hall call signal input to the slave 2-car controller 2b is transmitted to the master 2-car controller 2a via the 2-car transmission path 10.
[0027]
The master 2-car control unit 2a combines the hall call signal received from the 2-car transmission path 10 and the hall call signal received by the own car 2 car control unit 2a to create a hall call registration signal. Then, the created hall call registration signal is transmitted to the slave 2-car control unit 2b via the 2-car transmission path 10, and the hall call is sent via the operation control unit 3a of the own machine and the hall call input / output control units 7a to 7n. The response lamps of the registration devices 9a to 9n are turned on. Similarly, the hall call registration signal transmitted to the slave two-car control unit 2b also receives the response lamps of the hall call registration devices 9a to 9n via the driving control unit 8a to 8n via the operation control unit 3b. Light up.
[0028]
There are cases where two landing call registration devices 9a to 9n are installed on one floor. In this case, either one of the landing call registration devices is connected to the landing call input / output control units 7a to 7n on the first unit. The other landing call registration device is connected to the landing call input / output control units 8a to 8n on the No. 2 side. The operation after the transmission to the hall call input / output control unit is the same as that when there is one hall call registration device 9a-9n on each floor described above.
[0029]
The master two-car control unit 2a determines which unit should respond to the created hall call registration signal, passes the result to the operation control unit 3a of the own unit, and transmits the two-car transmission path 10 To the two-car control unit 2b of the counterpart machine. Similarly, the slave two-car control unit 2b that has received the response sharing also passes the result to the operation control unit 3b of the own machine. The operation control units 3a and 3b that have received the response sharing control the cars 4a and 4b of their own machine based on the information, and send the response to the response sharing floor for a response.
[0030]
There are car call registration devices 5a and 5b in the cars 4a and 4b, and when the passenger presses a button on his / her destination floor, the car call signal is sent to the own car via the car call input / output control units 6a and 6b, respectively. Are input to the operation control units 3a and 3b to create a car call registration signal. Similar to the hall call response sharing command received from the two-car control units 2a, 2b, the operation control units 3a, 3b are based on the car call registration signal, and the car 4a, Responds to point 4b.
[0031]
Next, the operation of the normal two-car control units 2a and 2b will be described with reference to the flowchart of FIG. First, the master two-car control unit 2a detects whether a hall call is newly generated from the hall call registration signal (step S1). When it newly occurs, the directionality of each car is detected from the information of the operation control units 3a and 3b in FIG. 1 (step S2). The directionality of the slave machine is detected by the master two-car control unit 2 a via the two-car transmission path 10. The direction of the detected car is stored in a memory.
[0032]
Then, according to the directionality of the car, which one of the three modes corresponds is classified (step S3). Here, the case where both are non-directional is classified as mode 1, the case where one is non-directional, the case where the other is directional is mode 2, and the case where both are directional are classified as mode 3. Thereafter, the processing for each classified mode is performed (steps S4, S5, and S6).
[0033]
Next, the processing of the master two-car control unit 2a in mode 2 will be described with reference to the flowchart of FIG. The floor and direction of the newly generated hall call are detected (step S11). Next, the position of each car is detected (step S12). The car position of the slave machine is detected via the two-car transmission path 10. It is determined from the detected floor call generation floor and the position of the car and the direction data of each car previously stored in the memory whether or not the stop floor of the non-directional car and the floor call generation floor match (step S13). . If they match, the car responding to the hall call is determined as the non-directional car (step S14). If not, it is next determined whether the hall call generation floor is within the front X floor of the directional unit (step S15).
[0034]
The X floor is variable data depending on the specifications of the building, and here it is assumed to be the second floor. Therefore, in step S15, if it is within the X floor, that is, within the second floor, the process proceeds to step S16, and the number of the machine that responds to the hall call is determined as the directional car. On the other hand, in step S15, if it is a hall call ahead of the X floor, the process proceeds to step S17 to determine whether it is within the upper and lower X floors of the non-directional unit.
[0035]
The X floor here is also variable data according to the specifications of the building, and is assumed to be the second floor here. Therefore, if it is determined in step S17 that it is within the X floor, that is, within the second floor, the process proceeds to step S14, and the car that responds to the hall call is determined to be a non-directional car. On the other hand, if it is determined in step S17 that the hall call is ahead of the X floor, the process proceeds to step S18, and it is determined whether the number of stop floors of the building is smaller than the Y floor.
[0036]
The Y floor is data on the number of floors for distinguishing whether the building is a higher floor or not, and here it is assumed to be the 16th floor. Therefore, in step S18, in the case of a building smaller than the 16th floor (= Y), from the information of the position of each car and the floor call generation floor, the floor travel distance to respond to the hall call for each car Whether it exists is calculated (step S19). As a result, the car having the shorter mileage is determined as the answering machine for the hall call (step S20).
[0037]
On the other hand, in the case of a building larger than the 16th floor (= Y) in step S18, the travel time required to respond to the hall call for each car is predicted from the information on the position of each car and the floor on which the hall call is generated. (Step S21). The calculation method of travel time is a well-known technique, the position of the car, the arrival time to the landing call that the car is to share, the arrival time to the car call registered in the car, the door opening and closing time To all. As a result, the car having the shorter predicted travel time is determined as the answering machine for the hall call (step S22).
[0038]
In the same situation as the conventional example shown in FIG. 6, when the car that responds to the hall call generated in this way is determined, the car No. 1 as shown in FIG. To respond. That is, as shown in FIG. 6, when the first floor 23 is traveling on the fourth floor in the up direction and the second floor 24 is in the non-directional stop on the first floor, the eighth floor down hall call 22 is generated. Since the conditions of steps S13, S15, and S17 in step 3 are not applicable, the process proceeds to step S18. In step S18, the number of stop floors of the building is smaller than the 16th floor (= Y), so the process branches to YES, and the first unit 23 having the shorter travel distance is determined as the response car by the travel distance calculation in step S19. . As a result, the passenger waiting at the 8th floor landing responds that the first car 23 responds to the appearance, and the far second car responds with the car stopped just before as shown in FIG. You can prevent the discomfort that comes.
[0039]
In the situation as shown in FIG. 8, that is, when the No. 1 machine 43 is traveling in the up direction on the 6th floor and the No. 2 machine 44 is stopped in the non-directional direction on the 1st floor, the 15th floor down landing call 42 is generated. Since the conditions of S15 and S17 do not apply, the process proceeds to step S18, and since the number of stop floors of the building is 16 floors, the process proceeds to the travel time calculation of step S21, and the travel time is calculated.
[0040]
In this travel time calculation, for Car 1 No. 43, since the car call 41 is registered on the 9th and 11th floors, the arrival time from the 6th floor to the 9th floor, the door opening and closing time on the 9th floor, The arrival time up to the 11th floor, the door opening and closing time on the 11th floor, and the arrival times from the 11th floor to the 15th floor are added together to calculate the traveling time until the landing call 42 on the 18th floor down. On the other hand, the second unit 44 calculates the arrival time from the second floor to the 18th floor down. As a result, the second unit 44 having a short travel time is determined as the response unit.
[0041]
Therefore, as shown in FIG. 5, the second machine 44 can go to the 15th floor while the first car 43 is responding to the car call 41 on the way. As a result, as in the case of the conventional example shown in FIG. 8, the passenger waiting on the 15th floor does not respond easily to the 15th floor, but the other unit (Unit 2) stops without moving at all. It is possible to prevent the user from having the discomfort of staying.
[0042]
【The invention's effect】

[0043]
According to the elevator control apparatus of the second aspect of the present invention, the control method of the first aspect of the invention is used, and the two-car control unit is stopped in one direction and the other one operates in a direction. When a new hall call occurs, the rules for determining the response sharing units are applied in descending order of priority, and the number of stop floors is a predetermined value according to the number of floors in the building where the elevator is installed. by applying rules based on the distance traveled when less than, to respond cage Unit travel distance shorter until landing call occurrence floor, traveling when the stop number bed is larger than a predetermined value By applying time-based rules and responding to the car of the car with the shorter estimated travel time until arrival at the landing call generation floor, the optimal car is determined and responded to the landing call. Discomfort for customers who It can be so no.
