2. Description of the Related Art Conventional elevators have a structure in which one car is arranged in one hoistway, such as a hydraulic plunger (hydraulic elevator) or a roll-up type elevator for relatively small volume transportation. Except for this, most of them are cages and counterweights that are connected in a rope-like manner.

4 is provided and arranged, and the car for rotating the drive motor of the hoisting machine 5 in the machine room above the hoistway in the normal direction or in the reverse direction moves upward and downward in accordance with the rotational direction.

Has the advantage of being small. Furthermore, it is a system that has been established in terms of performance and safety by the technology that has been cultivated from the past.

[0005] In recent years, there are many cases where a plurality of elevators in a building are installed side by side as the building becomes taller and larger, and in that case, in order to improve the operation efficiency of the elevator and the service for the users of the elevator. Group control is performed so that an elevator that responds to a landing call on each floor can be reasonably and quickly assigned by using a small computer such as a microcomputer. In addition to these current systems, various new systems have been proposed to meet the demands of skyscrapers (for example, the magazine NIPPON STEEL MON).
Those described in THLY). One of them is an elevator that moves vertically and horizontally without using a rope. The running paths are installed vertically and horizontally in the building, and not only one car can move up and down, but also horizontal movement.

This system is different from the conventional elevator in which one car is installed in one hoistway, it is possible to run a plurality of cars in one hoistway, and passenger transportation can be carried out very efficiently. .

FIG. 32 is an example (illustration in the above-mentioned document) showing an operational image of a vertically and horizontally moving elevator. Install the secondary conductor 10 of the linear motor in each of the multiple cars 9,
Linear motor primary conductor (coil) 11 installed in the hoistway
A drive thrust is obtained by means of and, as a safety device, a brake 12 and a shock absorber 13 for alleviating impact due to mutual collision of cars, and a superconducting magnet 14 for connecting traveling are installed. Furthermore, a lifter 15 and a horizontal (horizontal) movable plate 16 for traveling (horizontal) are installed on the top floor, and a hydraulic jack 17 is also installed on the bottom floor, which makes it possible to travel multiple cars in one hoistway. .

The basic configuration showing the drive power supply method is a method of installing a control device in correspondence with the number of cars. This is a system in which the primary coil on the hoistway side is divided into a plurality of sections, and the connection between the primary coil and the control device of each car is switched for each section via a switcher as the car travels. A drive power supply method has already been proposed in Japanese Patent Laid-Open No. 4-260588.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in FIGS. In FIG. 2, 40l to 40m are hall call registration buttons installed in each hall of the building, and 42 is an operation management control unit.
41 and a hall call transmission line that connects the hall call registration buttons 40l to 40m, 43l to 43n are vertically and horizontally movable elevators having a single control unit, 44l to 44n are elevator positions and speeds,
Elevator information communication path for transmitting and receiving information about the elevator such as traveling direction, boarding load, closed section to the operation management control unit 41, for example, radio waves, 45 for buildings, 46 to 49 for the top floor and middle floor and The hoistway has a traverse path (horizontal path) on the lower floor, and 50 is a runway connecting with an elevator hangar for sheltering or supplementing depending on traffic conditions. When any of the hall call buttons 40l to 40m is pressed at the hall, a signal is input from the button to the operation management control unit 41 via the transmission path 42. The operation management control unit 41 determines the floor and direction of the registered hall call from the input signal, and comprehensively evaluates each elevator from the elevator information transmitted from each elevator 43l to 43n to find the optimum elevator. The hall call is assigned to 43i via the communication path 44i. As an evaluation index for assigning a hall call, the distance between the hall call floor and the elevator, the estimated arrival time until the hall call is answered, the degree of dispersion (congestion) of the entire elevator, and the like can be considered. Various other evaluation indexes and evaluation methods are conceivable, but the hall call allocation method will be omitted.

The elevator 43i, to which the hall call is assigned, travels on a predetermined route and responds to the hall call to let a waiting passenger get on at the hall. Then, in response to the car call registered by the passenger, the passengers are sequentially answered to the destination floor and the passenger is alighted at the destination floor. Further, the operation management control unit 41 determines whether or not there is a closed section of another elevator from the current position of the elevator to the next stop position based on the elevator information transmitted from the elevators 43l to 43n every predetermined time. If there is a closed section, the stop command is output to the elevator so as to change the next stop position of the elevator attempting to enter the section to a position before the section and stop at the position. The elevator that has received the above command brakes at that time and stops by the braking command from the single control unit.

Next, a series of flow from determination of change of the next stop position of the elevator to braking of the elevator will be described in detail with reference to FIG. The operation management control unit 41 receives elevator information such as a car call, position, speed, traveling direction, boarding load, and closed section of each elevator, and also an elevator information transmission / reception unit for transmitting information such as hall call allocation and stop command. 61x and an operation control unit 62 for allocating a hall call registered via the hall call transmission line 42 to an optimum elevator, and a next stop for determining whether the next stop position of the elevator needs to be changed based on the elevator information. The position changing unit 63 is included. The unit control units 60l to 60n transmit the blockage section calculation units 65l to 65n that calculate the blockage section of the elevator from the elevator position, the speed, and the traveling direction and other elevator information including the blockage section, and the operation management control unit 41. Elevator information transmission / reception units 61l to 61n that receive allocation calls and stop commands from the elevators, and next stop position setting units 64l to 64 that set the next stop position of the own elevator by the received allocation calls, stop commands, and car calls.
It consists of n. Although various means for outputting an instruction to stop the elevator can be considered, in the present embodiment, it is assumed that a dummy call is output in the same manner as an ordinary assigned call to control the traveling of the elevator.

Elevator information including the closed sections calculated by the closed section calculation units 65l to 65n is constantly transmitted from the elevator information transmission / reception units 61l to 61n of the elevators through the elevator information communication paths 44l to 44n. The elevator information transmitting / receiving unit 61x in the operation management control unit 41 receives the information and outputs the information to the next stop position changing unit 63 via the information path 51. In the next stop position changing unit 63, based on the elevator information, whether there is a closed section of another elevator from the current position of the elevator to the next stop position, that is, whether all elevators collide with each other is checked, If predicted, a dummy call is output from the elevator information transmission unit 61x to the elevator so as to stop the elevator before the closed section. When a dummy call is received by the elevator information transmission / reception unit 61i in the elevator single control unit 60i, the dummy call is output to the next stop position setting unit 64i via the information path 52i. When a dummy call is input, the next stop position setting unit 64i responds to the call and stops at the target position before the closed section.

Next, the concept of the closed section will be described with reference to FIGS. FIG. 1 is a conceptual diagram of the closed section, where the elevator 32n stopped at mF is the primary coil 31 of the linear motor.
This is the state immediately before the vehicle is energized to m, 31 (m + 1) and departs upward, and the elevator 32 (n-1) has started deceleration because the elevator 32n is stopped in the traveling direction. It is a thing. After that, in terms of the positional relationship between the two, the elevator 32n is the leading elevator, the elevator
32 (n-1) is called a subsequent elevator. Floor (m +
1) Subsequent elevator that was traveling with F as the destination floor
32 (n-1) is at least (m- in order to avoid a collision with the preceding elevator 32n stopped at the floor mF.
1) You must stop by F. The primary coil 31 so as to decelerate with respect to the succeeding elevator 32 (n-1)
(M-3) to 31 (m-1) are sequentially excited to generate (m-1) F
If you stop it, the collision will be avoided. This (m-1) F
When the elevator is stopped at the position of 31 (m-
The primary coil of 1) is excited and holds the position. At this time, the energized section of the primary coil 31m is called a closed section of the preceding elevator 32n, and is a section in which another elevator cannot enter to avoid a collision. However, the preceding elevator 32n is on the floor mF and the following elevator (n-
If 1) stops at floor (m-1) F and the two elevators are adjacent to each other and the primary coil 31m fails, the stopped state at floor mF cannot be maintained and the elevators collide. Therefore, safety can be improved by adding at least the section of the primary coil 31 (m-1) immediately before the energization section to the closed section. This is because even if the primary coil 31m fails, the collision can be avoided by exciting the primary coil 31 (m-1). Hereinafter, this section will be referred to as a safe section in the closed section. The larger this safety section, the smaller the possibility of collision. Furthermore, when trying to stop the trailing elevator 32 (n-1) that is running, it cannot be stopped immediately because it has a speed, and depending on the speed from the start to the stop of braking. Braking distance is required. If another elevator is present within this distance, it will collide, so in order to avoid the collision, it is necessary to set at least the braking distance as the closed section in the traveling elevator. Hereinafter, the position where the running elevator can start and stop braking is called the advancer position. Naturally, when the elevator is stopped, the advancer position is the stop position of the elevator, and it constantly changes depending on the speed. A feature of the advancer position is that the higher the speed, the longer it extends. Similarly, when the primary coil in the closed section is out of order, the braking distance becomes long,
Considering safety, a few sections are added to the braking distance to form a closed section. Similar to the above, the larger the safety section, the higher the safety. In other words, the elevator 32n trying to start traveling brakes immediately after departure and 31 (m +
It is possible to stop in 1), and if the safety section is one section, the closed section of the elevator 32n is 31 (m-1) to 31 (m +
2). Although FIG. 1 shows an example of a closed section of an elevator that is traveling in the vertical direction, it is roughly classified according to the traveling direction and state of the elevator (a) in a stopped state, (b) in the vertical traveling direction, (C) There are three cases of left and right lateral running. Considering the closed section with the safe section as one section, it becomes as follows. In a stopped state in which the elevator is moving in the vertical direction, the elevator travels from above and below, so the blocked section 81 of the stopped elevator is three sections including the stop section and the two sections above and below. In this state, the closed section 83 of the stopped elevator includes a stop section, two sections above and below, and three sections above and below the middle direction.
In the vertical traveling state, the blockage section 86 of the elevator is from one section behind the current elevator position to one section before the advisor position 85. In the lateral traveling state, the block section 89 of the elevator is the section from the current position to the section in front of the adviser position 88 in the upper, lower, middle and lower sections. As shown in the flowchart of FIG. 7, the closed section is uniquely determined by the traveling direction and state of the elevator. The concept of the closed section has been described above. Next, a method of changing the next stop position of the elevator depending on the closed section will be described with reference to FIGS. 5 to 6. Figure 5 shows a 4-shaft, 10-story building with traverse floors on 1, 5, and 10th floor, elevator 90 is stopped on 8th floor, and elevator 91 is on 7th floor.
FIG. 6 is a diagram showing a state in which the vehicle is traveling upward toward the vehicle. If this building is divided into shafts and floors, it will be 4 x 10
It is considered that the building consists of a total of 40 blocks (sections). Each of these blocks can correspond to the two-dimensional matrix 98 shown in FIG. Shaft is x-axis, floor is y
Assuming an axis, the elevator 91 located on the 2nd shaft 2F
The position of is represented by (2, 2). The two-dimensional matrix is used to represent the closed section. The number of sections that are not closed sections is 0, and the number of closed sections is 1 or more, and the number indicates the identification number of the elevator. That is, the section 1 is the block section of the NO1 elevator. The next stop position changing unit 63 clears the old block section data of each elevator in the two-dimensional matrix 98 to zero and also sets the new block section data which is one of the elevator information transmitted from each elevator to the two-dimensional matrix 98.
Are sequentially set to update the closed section data. For example,
The block section 92 of the elevator 90 has 2 shafts 7-9F.
Therefore, set 90 to (2,7) to (2,9),
Since the closed section 93 of the elevator 91 is 1 to 5F with two shafts, 91 is set to (2, 1) to (2, 5).
Therefore, the matrix data for 2 shafts is (2, 1)
~ (2, 5) = 91, (2, 6) ~ (2, 10) = 0,
(2,7) to (2,9) = 90. After setting the closed sections of all the elevators, it is checked whether there is a closed section of another elevator between the current position 2F and the next stop position 7F of the succeeding elevator 91, and if there is, the elevators collide with each other. 6 in front of the closed section 92 of the elevator 90 with respect to the subsequent elevator 91
The dummy call of 6F is output so as to stop at F. The elevator 91 receives the dummy call and stops at 6F to avoid a collision with the elevator 90.

Next, the flow of predicting an elevator collision from the closed section of each elevator, deciding the elevator to be stopped, and outputting a dummy call to stop before the closed section is shown in FIG. ~ It demonstrates using the flowchart of FIG. As shown in the flowchart of FIG. 8, the next stop position changing unit 63 updates the closed section data of all elevators at regular intervals, and then determines whether the next stop position of each elevator should be changed to avoid collision between elevators. To check. When it should be updated, the target elevator is extracted, a new stop position is calculated, and a dummy call is output to the elevator at a new next stop position.
As shown in the flowchart of FIG. 9, the closed block updating process sets the new closed block in the matrix 98 after clearing the old block block from the matrix data (x, y) for each elevator. This process is performed for all elevators (steps 1101 to 1104). Next, with regard to the check processing for changing the next stop position, a method of extracting the target elevator and calculating a new next stop position will be described based on the flowchart of FIG.

First, the current position of the elevator I (SS _I , F
S _I ) and the next stop position (SE _I , FE _I ) are extracted (step 1202), and the two-dimensional matrix data from the current position of the elevator I to the next stop position is not 0 and a number other than the elevator I is It is checked whether it exists (steps 1205-1206). If there is a number other than the elevator I other than 0, it is determined whether the elevator I has a vertical direction or a horizontal direction (step 1207). Next, the vertical direction is determined for those having vertical directionality (step 1208), and the lateral direction is determined for those having horizontal directionality (step 1211), and the vehicle is traveling upward. If so, a new next stop position is set to (SH, FL-1) (step 12
If the vehicle is traveling downward, the new next stop position is set to (SH, FL + 1) (step 1210). If the vehicle is traveling right, the new next stop position is set to (SF- 1,
FL) (step 1212), when traveling to the left, a new next stop position (SH + 1, FL) (step 1212)
13) The above target elevator extraction and new next stop position calculation are performed for all elevators.

As described in detail above, in the control device for the vertically and horizontally moving elevator according to the present embodiment, the blockage section of each elevator is calculated, and the blockage section of another elevator is calculated between the current elevator position and the next stop position. When the elevators collide with each other, that is, when the elevators are predicted to collide with each other, the elevators are stopped in front of the closed section, so that the collision can be avoided and the vehicle can be safely run vertically and horizontally.

Further, in this embodiment, the operation management control unit centrally manages whether or not a collision occurs, but each elevator inputs information of other elevators and the elevator itself manages collision avoidance. Therefore, the safety can be further improved.

In the present embodiment, the concept of a closed section that prohibits the entry of another elevator is used, and when there is a closed section of another elevator between the current position of the elevator and the next stop position, the block before the closed section is placed. The basic method of the control device for the vertically and horizontally moving elevator, which avoids collision between the elevators by stopping the elevator as a new next stop position, has been described. In describing the basic method, the case where both elevators are on the same straight line is taken as an example. It was also stated that the closed section is uniquely determined by the elevator status and direction of travel. Therefore, next, a specific method of calculating the closed section in each state after being uniquely determined will be described. Furthermore, when traveling so that the elevators cross each other, it is difficult to detect that there is a block section of another elevator between the current elevator position and the next stop position, unlike when both elevators are on a straight line. Therefore, a method of determining the closed section will be described so that the closed section can be reliably detected. Furthermore, the timing of updating the closed section will be described.

In this embodiment, the method of calculating the closed section of the elevator which is in a stopped state when trying to travel in the vertical direction or the horizontal direction is shown in the flowcharts of FIGS. 11 to 12.
This will be explained using 13. In FIG. 13, (a) shows a closed section 204 of the elevator 201 which is in a stopped state due to an upward travel, and is shown from a start position 202 to an end position 203, and (b) shows a downward travel. The closed section 208 of the elevator 205 that is in the stopped state is shown from the start position 206 to the end position 207, and (c) is the closed section of the elevator 211 that is in the stopped state and is scheduled to travel to the right.
214 is shown from the start position 212 to the end position 213, and (d) is shown from the start position 216 to the end position 217 of the closed section 218 of the elevator 215 which is in the stopped state due to the planned traveling to the left. Is. Also, FIG. 11 shows FIG.
FIG. 12 is a flowchart for obtaining the start position and the end position of the closed section at the time of the planned stop in the vertical direction shown in (a) and (b), and FIG. 12 is the horizontal direction shown in FIGS. 13 (c) and (d). 6 is a flowchart for obtaining a start position and an end position of a closed section at the time of planned stop. In the calculation of the closed section, the safety section SFB in the planned traveling direction, the safety section SBB in the rear and the side safe section SSB in the planned traveling direction are considered.

First, a method of calculating the start position and the end position of the closed section of the elevator I, which is in the stopped state due to the planned running in the vertical direction, will be described with reference to the flowchart of FIG. The current position (SS _I , FS _I ) of the elevator I is read (step 1401) and it is judged whether the elevator I is going to travel upward (step 1402). , FLS) is the current position (SS
_I , FS _I ) subtracted the rear safety section SBB (SS
_I , FS _I- SBB), and the end position (SHE, FL
E) is a safe section S in front of the current position (SS _I , FS _I )
FB is added (SS _I , FS _I + SFB) (step 1403). If it is planned to be in the downward direction, the start position (SHS, FLS) of the closed section is the current position (SS _I , FS _I ) plus the rear safe section SBB (SS _I , FS _I + SB).
B), and the end position (SHE, FLE) is the current position (SHE, FLE)
S _I , FS _I ) plus the safety section SFB ahead (S
S _I , FS _I- SFB) (step 1404). Finally, when the elevator I is located near the terminal floor, the y-coordinate values FLS, F of the start position or end position of the closed section
Since LE may exceed the highest floor or the lowest floor, FLS and FLE are corrected to the lowest floor or the highest floor at that time (step 1405).

In the calculation of the closed section, the safe section is considered as in the embodiment of the invention of claim 2. In FIG. 15, (a) shows the closed section 235 of the elevator 231 in the upward traveling state from the start position 233 to the end position 234, and 232 indicates the advancer position of the elevator 231. (B) is an elevator that is running downwards 236

It is a flowchart which calculates | requires the start position and end position of the block area | region at the time of a longitudinal running shown to (b).

A method of calculating the start position and the end position of the closed section of the elevator I that is running vertically will be described with reference to the flowchart of FIG. The current position (SS _I , FS _I ) and speed of elevator I are read (step 170
1), from the current position and speed, advancer position (A
PX, APY) is calculated (step 1702). X-coordinate APX of advancer position becomes x-coordinate SS _I of the current position for the elevator is the vertical travel. The calculation method is not directly related to the present invention, and therefore the description is omitted. Next, it is determined whether the elevator I is traveling in the upward direction (step 1703), and if it is scheduled in the upward direction, the start position (SHS, FLS) of the closed section is the current position (SS _I , FS _I ).
The rear safety section SBB is subtracted from (SS _I , FS _I −
SBB), and the end position (SHE, FLE) is the safety section SFB in front of the advancer position (SS _I , APY) (SS _I , APY + SFB) (step 1704). If the vehicle is traveling downward, the start position (SHS, FLS) of the closed section is the current position (SS _I , FS).
_I ) to the rear safety section SBB (SS _I , FS
_I + SBB) and the end position (SHE, FLE) is the advance safety section SFB subtracted from the advancer position (SS _I , APY) (SS _I , APY-SFB) (step 1705). When the last elevator I is located near the terminal floor, the y-coordinate values FLS, FLE of the start position or end position of the closed section may exceed the uppermost floor or the lowermost floor.

57 indicates the advancer position of elevator 256. Further, FIG. 16 is a flowchart for obtaining the start position and the end position of the closed section during the lateral traveling shown in FIGS. 17 (a) and 17 (b).

A method of calculating the start position and the end position of the closed section of the elevator I which is running laterally will be described with reference to the flowchart of FIG. The current position (SS _I , FS _I ) and speed of elevator I are read (step 190
1), from the current position and speed, advancer position (A
PX, APY) is calculated (step 1902). The y-coordinate APY of the advancer position is the y-coordinate FS _{I of the} current position because the elevator is traveling laterally. The calculation method is not directly related to the present invention, and therefore the description is omitted. Next, it is determined whether the elevator I is traveling to the right (step 1903), and if it is scheduled to move to the right, the start position (SHS, FLS) of the closed section is the current position (SS _I , FS _I ).
To the side safety zone SSB (SS _I , FS _I
+ SBB), and the end position (SHE, FLE) is the advanced safety section SFB from the advancer position (APXFS _I ) and the side safety section SSB is subtracted (A
PX + SFB, FS _I −SSB) (step 190)
Four). If the vehicle is traveling to the left, the start position (SHS, FLS) of the closed section is the safe position SSB on the side from the current position (SS _I , FS _I ) (SS _I , FS _I + SB)
B), and the end position (SHE, FLE) is a safe section S ahead of the advancer position (APX, FS _I ).
FB and side safety zone SSB were subtracted (APX-S
FB, FS _I- SSB) (step 1905). Finally, when the elevator I is located at the terminal floor or near the terminal hoistway, the values FLS, SHE, FLE of the x or y coordinates of the start position or the end position of the closed section are the top floor, the bottom floor or the leftmost hoistway. , The right-most hoistway may be exceeded, and then FLS, SHE, FLE are corrected to the lowest floor, the top floor or the leftmost hoistway, and the rightmost hoistway (step
1906).

As described in detail above, in the control device for the vertically and horizontally moving elevator according to the present embodiment, it is determined depending on in which direction the closed section of the elevator which is traveling in the lateral direction is planned to travel. Therefore, an accurate closed section can be calculated, and safe traveling can be performed without colliding with an elevator in a lateral traveling state.

Further, in the next embodiment, when the elevators travel so as to intersect each other, the elevator that first arrives at the position where the traveling routes of both elevators intersect is prioritized to determine the closed section of the elevators. ,
A method of determining the closed section will be described with reference to FIGS. FIG. 18 is a signal transmission block diagram of the control unit according to the present invention incorporated in the next stop changing unit 63 of the operation management control unit 41. The next stop position changing unit 63 is a core unit for changing the next stop position.
631, and the transverse prediction unit 632 that predicts to perform the transverse direction within a predetermined time, the transverse prediction unit 632, and the current position of the transverse elevator when the transverse prediction unit 632 predicts to perform transverse movement. To the position where the traverse movement ends, and the route crossing determination unit that determines whether the movement route from the current position of the vertical elevator to the next stop position intersects
633 and the route intersection determination unit 633, when it is determined that the travel routes of both elevators intersect each other, the time to reach the route intersection position of the advancer position is calculated, and the priority of the elevator that arrives first is given priority. Decision Department 634
Made of.

Since the basic part of the series of steps from the determination of the change of the next stop position of the elevator to the braking of the elevator has already been described in the above embodiment, the description thereof will be omitted. From the prediction of lateral movement that is directly related to, the priority of both elevators whose travel routes intersect is determined to be high and the priority of both elevators whose travel routes are intersected is determined to be high. The flow until setting the closed section of the elevator will be described with reference to the flowcharts of FIGS. 18 to 22.
The elevator information transmission / reception unit 61x in the operation management control unit 41 receives each elevator information that is constantly transmitted, and the elevator travel route, estimated departure time, elevator status, current position, speed, traveling direction, etc. are included in the information. Information path 51
It is input to the traverse prediction unit 632 via. Rise prediction unit 632
Then, based on the elevator information, it is predicted whether to move in the horizontal direction within a predetermined time (step 2501), and when it is predicted to move transversely (step 2502), the travel route of another elevator via the information path 51. It instructs the route intersection discriminating unit 633 so as to discriminate whether or not it may intersect with and outputs transverse elevator information. In response to the command, the route intersection determination unit 633 receives the elevator information of the transverse elevator and the elevator information of another elevator obtained from the elevator information transmission / reception unit 61X via the information path 51 from the current position of the transverse elevator to the position where the transverse movement is completed. It is determined whether or not the movement route of the above and the movement route of the other elevator from the current position to the next stop position intersect (step 25).
03). Then, when it is determined that the traveling route of the transverse elevator intersects with the traveling route of another elevator (step 2504), the route intersection determination unit 633 determines which elevator is to be preferentially traveled by using the information path 51. The priority determining unit 634 is instructed via the above, and information on the route crossing target elevator including the transverse elevator and the route crossing position are output. Upon receiving the command, the priority determination unit 634 calculates the time until the advancer position reaches the route intersection position from the elevator information of the route intersection target elevator input from the route intersection determination unit 633, and the route intersection position is first determined. Decide which elevator to reach (step
2505). Next, the priority determining unit 634 outputs the route crossing position at the same time as instructing the elevator to perform the calculation of the closed section again from the elevator information transmitting / receiving unit 61X via the information path 51 (step 2506). The elevator that has received the command and data at the elevator information transmission / reception unit 61i sets the route from the current position to the route crossing position as the closed segment in the closed segment calculation unit 65i, and again the elevator information in the operation management control unit 41. It transmits to the transmitter / receiver 61X. The above outlines the signal flow from the prediction of lateral movement to determining the priority of both elevators where the travel route intersects and setting the blocked section of the elevator with high priority.Next, , A specific example in which the movement paths of the elevators intersect with each other will be described in detail with reference to FIGS. FIG. 19 is an image diagram showing a case where the movement paths of elevators intersect with each other.
In a 4-shaft 10-story building with a traverse floor on the 10th floor,
The elevator 301 is traveling upward on the 3rd floor, and on the moving route 303, the 4th floor car call 304 and the 8FUP hall call 305
The elevator 302 is on the 1st floor.
The door is open, and the car is called on the second floor on the moving route 306. 307
And 3F car call 308 and 7F car call 309. In each elevator information received by the elevator information receiving unit 61X in the operation management control unit 41, the moving route of the elevator, estimated departure time, elevator state,
The traveling direction and the current position are as shown in FIG. 20, and the moving route 303 of the elevator 301 and the moving route 306 of the elevator 302 are, as shown in FIGS. It is expressed in a lined form. Index 1 indicates the elevator status, current position, and direction of travel, and index 2 indicates the next stop position and the estimated time and direction of departure from that position, and 3 and subsequent positions are positions that sequentially stop and the estimated time and direction of departure from that position. At the end of the index, there is a value (99, 99) indicating the end of the travel route.

First, the horizontal movement search method will be described with reference to FIGS.
This will be described with reference to the flowchart of. The travel route and the estimated departure time are read from the information table of each elevator shown in FIG. 20 (step 2602), the flag FLG is cleared, and the current position is set as back data (step 2602).
2603). The flag FLG is used to search for the start position and end position of the transverse line that satisfies the time condition. Flag FL
When G is 0, that is, when the traverse start position is searched (step 2605), it is checked if there is a change in the shaft number. If there is a change and the value is not 99 (step 2606), the previous At the stop position, in FIG. 20 (a), when the estimated time to depart from (1, 5) of index 3 is within the predetermined value DT _LMT (step 2607), when the time condition is satisfied, the position is traversed. Position and flag F
The LG is set to 1 (step 3608). Next, check if there is a change in the floor number, and if there is a change and the value is not 99 (step 2609), the previous stop position, (4) (3, 5) of index 4 in FIG. The end position is reached (step 2610). The traverse prediction unit 632 performs the above traverse movement search processing for all elevators (steps 2601 to 2613), and when there is an elevator scheduled for traverse movement that satisfies the time condition, the information path 51 is displayed.
The route crossing determination unit 633 is instructed to determine whether or not the route may intersect with the travel route of another elevator, and the transverse elevator information is output.

Next, the method for determining the intersection of the moving routes in the route intersection determining unit 633 will be described with reference to the flowcharts of FIGS. 21 to 24. FIG. 21 is the elevator shown in FIG.
Of the movement routes of 301 and the elevator 302, the movement route of the vertical traveling portion and the elevator number thereof are shown in a two-dimensional matrix, which is the data used for determining the intersection of the movement routes. First, for all elevators, search the travel route of the vertical traveling part, and enter the elevator number 2 in the part.
It is set in the dimension matrix (step 2701). Next, when there is a transverse moving elevator that satisfies the time condition (step 2703), the traverse start position and end position of the elevator are read (step 2704), and the elevator other than its own elevator is placed between the traverse start position and the end position. If a number exists, it is searched whether the number is 0, and if it exists, the position is saved (steps 2705 to 2708). Figure
At 21, the traverse start position 311 of the elevator 301 is (1, 5), the traverse end position 312 is (3, 5), and the elevator 302 other than the own elevator is present in the traverse section 313. Therefore, the route crossing position 314 is (3,
5), and the elevators to be crossed are elevators 302
Becomes The route intersection determination unit 633 performs the above-described route intersection determination process for all elevators (steps 2702 to
2709), instructing the priority determination unit 634 via the information path 51 to determine which elevator is to be preferentially traveled, and outputs the information of the route crossing target elevator including the transverse elevator and the route crossing position. .

Next, a method of determining the traveling priority of the route crossing target elevator in the priority determining unit 634 will be described with reference to the flowchart of FIG. First, check whether there is an elevator that has a moving route that intersects in the transverse section of the transverse elevator that satisfies the time condition (step
2802), if present, the elevator to be crossed is read (step 2803). Next, calculate the arrival time from the current position to the route crossing position for both elevators,
The elevator with the shortest arrival time is determined as the elevator with priority to travel (steps 2804 to 2807). The priority determination unit 634 performs the above processing for all elevators (steps 2801 to 2808), and commands the elevators with priority to travel to calculate the closed section again from the elevator information transmission / reception unit 61X via the information path 51. To do.

As described in detail above, in the braking device for a vertically and horizontally moving elevator according to this embodiment, it is predicted in advance that the elevators will meet each other and collide with each other, and the elevators arriving at the collision prediction position first will be given priority. Since the closed section of the elevator is set as a route to at least that position so that the elevator can travel, it is possible to avoid collision between the elevators at the meeting point and to perform safe traveling without unnecessary stop.

Furthermore, in the next embodiment, when traveling so that the elevators intersect each other, the priority of traveling is determined in the traveling direction of the elevators at the time of intersection, and the closed section of the elevator with high priority is determined. To do. Since the flow from the prediction of lateral movement excluding the determination of the priority elevator to the setting of one closed section of the elevator where the movement route intersects is the same as that in the above-mentioned embodiment, therefore, here, in the case of intersection, The priority determination method will be described with reference to the flowcharts of FIGS. 26 to 27. Figure 26
Is a priority table that determines the priority in the traveling direction of the elevator. First, it is checked whether or not there is an elevator having a moving route that intersects in the traverse section of the traverse elevator that satisfies the time condition (step 3002), and if it exists, the elevator to be intersected is read (step 3003). Next, the traveling direction at the time of the intersection of both elevators intersecting is read (step 3004), and the traveling priority is determined from the traveling direction priority table (step 3005). Then, the elevator having the higher priority is determined as the elevator having the traveling priority (steps 3006 to 3008). Priority determination unit
634 performs the above processing for all elevators (steps 3001 to 3009), and commands the elevator having priority to travel to execute the calculation of the closed section again from the elevator information transmitting / receiving unit 61X via the information path 51.

As described above in detail, in the control device for the vertically and horizontally moving elevator according to the present embodiment, it is predicted in advance that the elevators will meet each other and collide with each other in advance, and travel in the traveling direction when traveling at the collision prediction position. Since the priority is determined and the blockage section of the elevator with high priority is set as the route to at least that position, collision between elevators can be avoided and collisions can be avoided and safe and smooth driving can be achieved by providing traffic flow in a predetermined direction. .

Further, in the next embodiment, when traveling so that the elevators intersect with each other, the priority of traveling is determined by the shaft number where the elevators are located at the time of intersection, and the closed section of the elevator with high priority is determined. To do. Here is a diagram showing how to determine the priority when intersecting
This will be described with reference to the flowcharts of FIGS. FIG. 28 is a priority table in which priority is determined by the number of the shaft on which the elevator is located when intersecting. First, it is checked whether or not there is an elevator having a moving route that intersects in the transverse section of the transverse elevator that satisfies the time condition (step 3202), and if it exists, the elevator to be intersected is read (step 3203). Next, the traveling shaft at the time of intersection of both the intersecting elevators is read (step 3204), and the traveling priority is determined from the shaft priority table (step 3205). Then, the elevator having the higher priority is determined as the elevator having the traveling priority (steps 3206 to 3208). The priority determination unit 634 performs the above processing for all elevators (steps 3201 to 3209), and commands the elevators with priority to travel to calculate the closed section again from the elevator information transmission / reception unit 61X via the information path 51. To do.

As described above in detail, in the control device for the vertically and horizontally moving elevator of this embodiment, it is predicted in advance that the elevators will meet each other and collide with each other in advance, and the shaft number of the traveling position when traveling at the collision prediction position. In order to determine the priority of driving and to set the blocked section of the elevator with high priority as a route to at least that position, it is possible to avoid collision of elevators at the intersection of the elevators and to provide a traffic flow on a predetermined shaft for safe and smooth driving It will be possible.

In the present embodiment, when traveling so that the elevators cross each other, the closed section of the elevator having a high priority is reset as a route from the current position to the position where the moving route intersects by a predetermined priority condition. However,
When resetting, compare the areas of the closed section before resetting,
When the area becomes large, the safety can be further improved by permitting the resetting.

Now, the timing of updating the closed section will be described. In the above-described embodiment, the closed section is updated at predetermined time intervals, but other conditions are when the position of the elevator changes or when the elevator departs. A method of updating the closed section when the elevator position changes will be described with reference to the flowchart of FIG. The elevator information transmission / reception unit 61X in the operation management control unit 41 always receives the elevator information, and the information path 51 is followed by the next stop position change unit 63 at the current position P _{I of} each elevator.
After setting in the internal memory (step 3302), it is compared with the past position P _IB (step 3303), and if there is a change, the elevator information is updated via the information path 51 so as to update the closed section for the elevator I. A command is output from the transmitter / receiver 61X. Next, the past position data P _IB is updated (step 3305). The above processing is checked for all elevators (steps 3301 to 3306). here,
Although the operation management control unit 41 collectively determines whether to update the closed section, it is also possible to perform this determination by the unit control unit of each elevator.

As described above in detail, in the control device for the vertically and horizontally moving elevator according to the present embodiment, the closed sections of the elevators are updated appropriately, so that collisions between the elevators can be avoided and safe traveling can be performed.
