When the hall call control means 31 determines that the hall call can be registered, the hall call control means 31 generates response lamp information corresponding to the hall call registration information.

The response lamp information generated by the hall call control means 31 is transmitted to the corresponding hall information control means 10 via the common information transmission line 33a, the common information transmission conversion means 33, and the transmission line 7 for each car in order. At the same time, hall call registration information corresponding to the response lamp information is supplied to the allocation control means 32.

The hall information control means 10 which has received the response lamp information from the hall call control means 31 turns on and displays the response lamp 1b of the corresponding hall call registration button 1 as in the prior art.

On the other hand, the allocation control means 32, which has introduced the hall call registration information corresponding to the response lamp information, uses the conventional group information from the running state information of each car obtained through the single / group management transmission line 6. As in the case of the assignment by management, the most suitable car for the hall call is selected from the plurality (m) cars, and the assignment signal by the selection is transmitted via the single / group management transmission line 6 to the single control unit 5 of the car. Transmitted to

The single control unit 5 which has received the assignment signal from the assignment control means 32 is composed of a traveling control means 51 and a car-specific information control means 52, as in the prior art. The traveling control means 51 allocates the elevator car to the floor (destination floor).
, The travel direction and the travel distance of the elevator are calculated. The number-specific information control means 52 generates arrival forecast light information based on the calculation result, and transmits the information to the landing information control means 10 via the number-specific transmission line 7, so that the corresponding arrival forecast light 9 is lit and displayed. You.

As described above, the landing information control means 10
The hall call registration information, which is common information, is transmitted to the group management control unit 3 via the transmission line 7 for each unit, and from the corresponding single control unit 5 via the transmission line 7 for the same unit.
It is configured to receive the arrival forecast information that is the unit-specific information.

FIG. 2 shows a specific configuration of each common information transmission conversion means 33 of the group management control section 3. The landing information transmission control CPU 3 controls transmission on the side of the transmission line 7 for each car.
31; a common information transmission control CPU 332 for controlling transmission on the common information transmission line 33a side;
It is connected to the PUs 331 and 332 and includes a bidirectional RAM 333 accessible from both sides.

Each bidirectional RAM 333 provided for each machine
Is provided with a data table of landing information for each car, and FIGS. 3 to 5 show examples of simplified data tables.

That is, FIGS. 3 and 4 show the first machine and m
It shows the configuration of a data table relating to each landing information of a car, which includes arrival forecast light information (addresses A1 to An) of each stop floor (number of stop floors n) which is car-specific information and a call system which is common information. Response lamp information (addresses B1 to Bn) of each stop floor and call registration information (addresses C1 to Cn) for each call system, which is also common information, are configured corresponding to the respective addresses.

As described above, in the bidirectional RAM 333, one data table corresponding to the machine-specific transmission line 7 and different for each car is formed.

As shown in FIG. 5, the bidirectional RAM 333 stores the common information from the information on the unit-specific transmission line 7 shown in FIGS. 3 and 4 corresponding to the common information transmission line 33a. The data table relating to the information (response lamp information and call registration information) is stored in each address (a1 to an, b1 to
bn, c1 to cn, d1 to dn).

Here, the system classification of landing calls will be described. Conventionally, in group control of elevators, a plurality of cars are grouped on a certain floor,
Groups may place restrictions on service floors. Therefore, such grouping of hall calls is referred to as grouping of calls in elevator group management.

Next, the operation of the unit-specific information control means 52 of the single control unit 5 will be described with reference to the flowchart shown in FIG. The following description is based on the assumption that the single control unit 5 performs real-time processing as a master station for elevator control of the car.

That is, the information control means 52 for each machine of the main station.
Transmits a transmission command by a transmission address relating to the operation of the elevator of this unit, and a platform information control means 10 of each floor.
In order to output the data to the group management control unit 3 cyclically, the index I of the transmission address to be transmitted is initialized in step S1 as in the related art. Next, in step S2, the transmission address of the index I is transmitted to each hall information control unit 10 and the corresponding common information transmission conversion unit 33 of the group management control unit 3 via the transmission line 12 for each car.

On the other hand, the unit-specific information control means 52 of the single control unit 5 is transmitted from the group management control unit 3 via the single / group management transmission line 6 in the next step S3 as in the conventional case. It is separately determined whether or not the transmission address of the index I is the address of the own station, and if it is the transmission address of the own station, a call is made via the travel control means 6 and the single / group management transmission line 14 in step S4. Read the assignment signal,
In step S5, information on the arrival forecast light to the destination floor of the car is generated in accordance with the assigned signal, and the transmission line 1 for each car is generated.
2 to the corresponding landing information control means 8.

Next, at step S6, each unit information control means 52 determines whether or not the index I is the last index on the table, that is, the index for the last floor of the elevator on the data table, as in the prior art. Judge. The same applies to the case where the transmission address of the index I from the group management control device 3 is not the address of the own station in step S3.

If the index I of the transmission address is less than the final index, the unit-specific information control means 52 increments the index I of the transmission address (plus 1) in step S7, and performs step S2 and subsequent steps for the next transmission. repeat. If the index I reaches the final index in step S6, the process proceeds to step S6.
At step 8, the index I of the transmission address is initialized in order to return to the first address, and step S2 and subsequent steps are repeated.

As described above, the number-specific information control means 52 of each single control unit 5 operating as the main station transmits the information to the hall information control means 10 and the group management control unit 3 of each hall.
Outputs the transmission command signal cyclically.

Next, as described above, the common information transmission conversion means 33 of the group management control unit 3
Only common information is extracted from the data tables on each landing information side shown in FIG. 3 and FIG. 4, and a conversion process is performed to the data table on the common information transmission side shown in FIG. Will be described with reference to the flowcharts shown in FIGS.

FIG. 7 is a flowchart showing the operation of each landing information transmission control CPU 331 shown in FIG.

First, at step T1, the landing information transmission control CPU 331 sends a transmission command from the corresponding landing information transmission main station (the number-specific information control means 52 of the single control unit 5) via the number-specific transmission line 7. When the transmission address is received, in step T2, it is determined whether or not the transmission address is common information (response lamp information or call registration information). If not, the process proceeds to step T1 in preparation for reception of the next transmission address. Return.

In step T2, if the transmission address from the main station is the common information, in step T3, the landing information transmission control CPU 331 determines whether or not it is the transmission address of its own station. In step T4, the common information data (response lamp information) corresponding to the transmission address is read out from the bidirectional RAM 333.
At 5, the data (response ramp information) is transmitted to the corresponding hall information control means 10 via the number-specific transmission line 7,
The process returns to step T1 in preparation for receiving the next transmission address.

In step T3, the landing information transmission control CP
If U331 is not the transmission address addressed to the own station, the common information data (call registration information) is received in step T6, and in step T5, the data (call) is transmitted to the address of the bidirectional RAM 333 corresponding to the received transmission address. After writing the registration information), the process returns to step T1 in preparation for receiving the next transmission address.

As described above, the landing information transmission control CPU 3
Reference numeral 31 transfers and writes data from the landing information control means 10 to the bidirectional RAM 333 based on the transmission address from the car-specific information control means 52, depending on whether the transmission address is common information or whether it is the own station address. It has a function of processing or reading data from the bidirectional RAM 333 and transmitting the data to the corresponding landing information control means 10.

Next, the operation of the common information transmission control CPU 332 shown in FIG. 2 will be described with reference to FIG.

First, each common information transmission control CPU 332
Receives the address transmitted cyclically from the hall call control means 31 of the group management control unit 3 which is the master station of the common information transmission via the common information transmission line 33a in step U1. In step U2, the common information transmission control CPU 332 determines whether or not the received address is the transmission address of the own station.
At step U3, data (response ramp information) is received and introduced from the hall call control means 31 via the common information transmission line 13, and at step U4, whether the data (response ramp information) corresponds to the second system call information or not. Judge.

If it is determined in step U4 that the introduced data (response lamp information) corresponds to the second system call information, the data is transferred to the bidirectional RAM 333 for each system. The received data is written to the address of the bidirectional RAM 333 corresponding to the address obtained by subtracting the number of floors of the first system from the number of addresses of the common information, and the process returns to step U1 in preparation for receiving the next address.

If it is determined in step U4 that the data (response lamp information) does not correspond to the second system call information, the data is written to the address of the bidirectional RAM 333 corresponding to the received address in step U6. . When the writing operation to the bidirectional RAM 333 is completed in step U6, the process returns to step U1 to receive the next address from the hall call control means 31.

Next, in step U2, if the address of the landing call control means 31 as the main station is the transmission address of the own station, it is determined in step U7 whether or not the address is the second system call registration information. In the case of the second system call registration information, the data (call registration information) of the address obtained by subtracting the received address by the number of floors of the first system from the received address is read in step U8 in order to output the information separately for each system. .

After reading the data (call registration information) from the bidirectional RAM 333 in step U8,
If the transmission address addressed to the own station is not the second system call registration information in step 7, both of the bidirectional RAMs are executed in the next step U9.
The data (call registration information) read from 333 is supplied to the hall call control means 31 via the common information transmission line 33a, and the process returns to step U1 in preparation for receiving the next address.

As described above, the common information transmission control CPU 332
Receives data (response lamp information) via the common information transmission line 33a, transfers the data to the bidirectional RAM 333, writes the data (call registration information) from the bidirectional RAM 333, and reads the data (call registration information) from the bidirectional RAM 333 via the common information transmission line 33a. And a function of supplying the hall call control means 31.

As described above, each common information transmission conversion means 33 has two-way RAM 333 and two CPUs 33.
1, 332 have a common data area, and perform different transmission control to realize conversion processing of transmission data (unit-specific information and common information).

As described above, in the first embodiment of the present invention, the common information such as the hall call registration information and the response lamp information at each use floor and the information on each car such as the arrival forecast light are combined into one hall. Processed by the information control means 10, the single control unit 5 corresponding to the landing information control means 10 and the common information transmission conversion means 33 of the group management control unit 3 are connected by one unit-specific transmission line 7. .

Therefore, it is possible to reduce the number of hall information control means 10 installed corresponding to each floor, that is, the number of hall controllers and the number of transmission lines laid in the hoistway,
The configuration as a whole is simplified, and the installation work of the elevator and the like can be reduced.

(Second Embodiment) Next, an elevator group management apparatus according to a second embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIGS. That is, this second
The first embodiment shown in FIGS.
The difference from this embodiment is that if the single control unit 5 which is the master station of the transmission fails and the transmission command by the transmission address as the main station becomes impossible, the corresponding common information transmission conversion means 33 In particular, the difference is that the landing information transmission control CPU 331 detects this and substitutes for the failed single control unit 5 to play the role of transmission address transmission as a master station.

Therefore, if the group management control unit 3 detects a failure of the single control unit 5, the processing method of the landing information transmission control CPU 331 as the main station will be described in the first embodiment. This is different from the form described above.

That is, the landing information transmission control CPU 331 of the common information transmission conversion means 33 will be described with reference to the configuration shown in FIGS.
First, in step V1, an index I of a transmission address to be transmitted is initialized.

Next, at step V2, the unit-specific information control means 52 of the single control unit 5 detects whether or not transmission control by the index I of the transmission address is impossible as a master station.

Whether or not the unit-specific information control means 52 cannot perform transmission control as the master station is determined, for example, when the transmission address signal transmitted via the unit-specific transfer line 7 is interrupted for a predetermined time length. , The single control unit 5 can determine that a failure has occurred.

Therefore, the information control means 5 for each unit
When the landing information transmission control CPU 331 detects that the transmission control is impossible as the main station, the landing information transmission control CPU 331 becomes the transmission main station, and transmits the transmission address of the index I via the transmission line 7 for each machine in step V3.

Of course, if a failure of the single control unit 5 is not detected in step V2, the group management control unit 3 continues to function as a slave station for transmission, and the transmission from the main station for landing information transmission (ie, the single control unit 5). An address is received (step V4).

In any case, in the next step V5,
As in accordance with the flow shown in FIG. 7, the landing information transmission control CPU 331 determines whether or not the transmission address of the main station is the transmission address of the common information. The process returns to step V2 in preparation for reception or transmission of.

If it is determined in step V5 that the transmission address is the transmission address of the common information, it is determined in step V6 whether the transmission address is the transmission address of the own station.
In step V7, the corresponding data (response ramp information) is read from the bidirectional RAM 333, and in step V8, the corresponding landing information control means 10 is transmitted via the transmission line 7 for each car.
The response lamp information is transmitted to.

Next, in step V6, if it is not the transmission address of the own station, in step V9, data (call registration information) from the hall information control means 10 is received via the transmission line 7 for each car, and in step V10 Then, data is written to the address of the bidirectional RAM 333 corresponding to the received address.

Next, in step V11, according to the flow after step S6 shown in FIG. 6, it is determined whether or not the index I of the transmission address is the last index, that is, the index to the table corresponding to the last floor in the data table. If the index is not the final index, the index I of the transmission address is incremented in step V12, and steps V2 and thereafter are repeated for the next transmission.

In step V11, if the index I of the transmission address is the last index,
In step 13, the index I of the transmission address is initialized in order to return to the first transmission address, and the steps after step V2 are repeated.

According to the above processing, the common information transmission conversion means 33 of the group management control unit 3 performs the operation when the single control unit 5 which has been operated as the main station fails and the transmission command becomes impossible.
Immediately, the common information transmission conversion means 33 functions as a master station for data transmission controlling the transmission line 7 for each unit, instead of the single control unit 5 which has been the master station.

Therefore, according to the second embodiment,
In addition to the effects of the first embodiment, since the transmission control failure of the unit control unit 5 is detected and the common information transmission conversion unit 33 outputs the transmission command as the master station of the transmission instead, the provision of the unit It is possible to provide an elevator group management device that can continue normal elevator operation control even if the control unit 5 side fails.

(Third Embodiment) Next, a third embodiment of the elevator group management apparatus according to the present invention will be described with reference to FIG.
This will be described with reference to FIGS. The same components as those in the first embodiment shown in FIGS. 1 and 2 are denoted by the same reference numerals, and detailed description thereof will be omitted. In the third embodiment shown in FIG. 10, each single control unit 5 of each of two elevators (A and B, and C and D) is connected to one elevator.
The figure shows a case where data is transmitted by being connected to one unit-specific transmission line 7 (7i and 7j), but a plurality of single control units 5 connected to one unit-specific transmission line (7i or 7j) are shown. If so, the number is not limited to two and may be three or more.

Therefore, as shown in FIG. 10, the third embodiment is different from the first embodiment in that the landing information of two elevators is transmitted through one transmission line 7 for each car. The landing information control means 10 is configured to control the arrival forecasting lights 9 and 9 and the landing call registration buttons 1 and 1 for two units (A and B or a plurality of units of C and D).

In the third embodiment, since the information on the two elevators is transmitted on the same transmission line on the transmission line 7 for each car, the common information conversion means 33 of the group management control unit 3 also uses A, B The data tables of the signals transmitted through the landing information transmission lines 7i and 7j of the car Nos. And C and D have the structures shown in FIGS. 11 and 12, respectively.

In the common information conversion / transmission means 33, the data table of the signal transmitted on the common information transmission line 33a is, as described in the first and second embodiments, a data table of FIG. Although only the common information is included in the data in the data table and the description is omitted, each unit control unit 5 and group management control unit 3 function in the same manner as in the first and second embodiments.

(Fourth Embodiment) Next, a fourth embodiment of the elevator group management apparatus according to the present invention will be described with reference to FIG.
This will be described with reference to the configuration shown in FIG.

That is, in this embodiment, in FIG. 10, each unit information control means 52 of the plurality of single control units 5
Each has a function of detecting the presence or absence of an abnormality in the transmission command output for each of the units, and is configured such that the master station of the transmission control is determined by a predetermined rule.

In the following description, among the individual control units 5, the individual control units 5 corresponding to the units A and C operate as the master stations of the transmission lines for the respective units, and correspond to the units B and D. It is assumed that the single control unit 5 functions as a slave station.

In FIG. 13, at step W1, the unit-specific information control means 52 of the single control unit 5 of the master station initializes the index I of the transmission address to be transmitted, and the unit-specific information control means 52 of the slave station at step W2. It detects whether or not the transmission address is transmitted from the transmission main station. If it is determined that there is no transmission address from the master station, step W
When the length of time without a transmission address exceeds a predetermined time (for example, one second) in step 3, the master station determines that a failure such as transmission failure has occurred.

If the time length with no transmission address does not reach the predetermined time, the flow returns to step W2, and returns to the state where the transmission of the transmission address from the master station is continuously checked.

In step W3, when it is detected that the length of time in which there is no transmission address exceeds a predetermined time (time over), the slave station (other unit control unit 5) which has detected that time length determines that the master station of transmission is in operation. In step W4, a transmission address of index I is generated and transmitted to the hall information transmission line 7.

Accordingly, in the next step W5, the unit-specific information control means 52 of the other single control unit which has newly become the master station is provided.
(Unit B or D) determines whether the transmission address of index I is the transmission address of its own station, and if it is the transmission address of its own station, in step W6, the transmission line 7 between the single unit and the group management The call assignment signal transmitted from the group management controller 3 via the group management control unit 3 is read, and at step W7, arrival forecast light information is generated and transmitted to the corresponding hall information control means 10 via the hall information transmission line 7.

At step W2, the original master station (A
If the transmission of the transmission address from the No. C and the No. C is normal, if the received transmission address is the transmission address of the own station in step W8, the transmission of the single unit is performed in step W9.
The call assignment signal is read out from the inter-group management transmission line 7, and the generated arrival forecast light information is transmitted to the corresponding landing information control means 10 via the landing information transmission line 7 in step W10.

Next, after the arrival forecast light information is transmitted in step W7 and step W10, respectively, and when the address received in step W5 and step W8 is not the own station address, in step W11, the single control unit 5 It is determined whether or not the index I is the last index of the data table.
The index I of the 12 transmission addresses is incremented, and step W2 and subsequent steps are repeated for the next transmission.

If the index I is the last index in step W11, the index I of the transmission address is initialized in step 13 in order to return to the first transmission address, and the steps from step W2 are similarly repeated.

With the above processing method, the unit-specific information control means 52b of the single control unit 5 detects that any of the master stations has failed, and switches from the function as the slave station to the function as the master station until then. The transmission address of the transmission command is sequentially output, and the group management control of the elevator can be smoothly continued.

Here, it has been described that when the single control unit 5 as the main station fails, the other single control unit 5 becomes the main station. However, similar to the other embodiments, the same single unit transmission line is connected to the same unit transmission line. The common information transmission conversion means 33 of the connected group management control unit 3 may be configured to be switched as the main station.

Therefore, in the elevator group management apparatus of the present invention, the common information transmission conversion of the plurality of single control units 5 and the group management control unit 3 connected to the same transmission line 7 with the hall information control means 10 is performed. Any one of the means 33
Is operating as the master station of the transmission line, and if the master station fails, the common information transmission conversion means 33 of the other single control unit 5 or the group management control unit 3 can immediately operate as the master station. it can.

In this case, priority is given to which single control unit 5 or common information transmission conversion unit 33 of the group management control unit 3 operates as the master station. For example, the priority is set in descending order of priority. What is necessary is just to shorten the time length set in step W3. For example, assuming that the set time of the A unit is 1 second, the set time of the B unit is 3 seconds, and the set time of the common information transmission conversion unit 33 is 5 seconds, the unit-specific information control unit 5 of the A unit
2 becomes the main station of transmission preferentially, and if the transmission of the A-unit becomes abnormal, the FB unit becomes the main station after 3 seconds, and the corresponding common information transmission conversion unit 33 becomes the main station after 5 seconds, and continues the transmission control. can do.

As described above, in the elevator group management apparatus according to the present invention, transmission is performed in accordance with a specific rule from among the information control means for each of a plurality of units and the corresponding common information transmission conversion means of the group management control unit 1. Therefore, even if an abnormality occurs in some of the single control units 5, the control units are disconnected, and the single control unit 5 of the normal unit or the common information transmission / conversion means controls input / output of the hall call. , The control of car assignment to the normal car and the lighting control of the arrival forecast light can be executed without any trouble.

[0089]

As described above, according to the first aspect of the present invention, common information such as hall call registration information and car-specific information such as arrival forecast light information are transmitted and received by the same hall information control means, and the same information is transmitted. Since it is transmitted on the landing information transmission line,
This makes it possible to reduce the number of control means at the landing and the number of transmission lines in the hoistway, thereby reducing the burden of elevator installation work and the like.
