DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device, and more particularly to an elevator operation control device capable of displaying the execution state of a plurality of operations and the execution state of a sequence in each operation in real time.

[0002]

2. Description of the Related Art An elevator has more than 100 types of operations, such as a control operation performed when an earthquake or fire occurs, a parking operation in which a switch is operated to stop at a specific floor, and an inspection operation for maintenance and inspection. And these have a priority relationship with each other. These operations are selectively executed in accordance with the state of switches during operation of the actual machine, the state of passengers, and the like. However, during operation, only one operation is not necessarily selected and executed, and several operations are executed in parallel.

When performing maintenance or inspection of an elevator or when a trouble occurs, it is necessary to know which operation is being performed by the elevator and which sequence is being executed during the operation. Often happens.

Conventionally, to deal with such a problem,
A keyword of a representative operation is determined, a keyword of a higher priority among the operations being executed is displayed on a display device, and a lamp corresponding to the operation being executed is turned on.

[0005]

However, in the prior art, in a limited display area, the number of operations that can be displayed is small, and for an operation for which no keyword is prepared, whether the operation is being executed or not is determined. I couldn't judge. Further, in order to display the execution states of all the operations, it is necessary to prepare many display lamps, and there has been a problem that the equipment becomes large. Then, for an operation with a high priority, it is possible to grasp whether the operation is being executed or not, but it is not possible to grasp which state in the processing sequence the operation being executed is executing.

[0006] Further, for an operation that has not been executed, it cannot be determined whether the reason is that the operation is prohibited by another operation or the start condition is not satisfied. Was.

The present invention has been made to solve such a problem.

[0008]

According to a first aspect of the present invention, execution permission / prohibition is set for a plurality of elevator operations, and priority is set for each operation to determine which operation is being executed. An operation processing means for grasping and indicating the state of permission / prohibition of execution of each operation and information indicating the operation being executed by numerical data of bits corresponding to the number of operations, and storing numerical data by the operation processing means. Storage means, selection means for selecting desired data from the numerical data stored in the storage means, and display means for displaying information on the data selected by the selection means. Is what you do.

[0009] As a result, for a plurality of elevator operations, the status of permission / prohibition of execution of each operation and which operation is being executed can be displayed in real time. Extremely useful information can be provided to the operator.

A second invention sets permission / prohibition of execution for a plurality of operations of an elevator, sets a priority for each operation, grasps which operation is being executed, and determines which operation is being executed. Operation processing means for expressing information indicating the permission / prohibition state of execution and the operation being executed by numerical data of bits corresponding to the number of operations;
For each operation permitted to be executed by the operation processing means, a sequence processing means for controlling an operation sequence of the operation and converting the execution state of each sequence into numerical data; and a numerical data generated by the operation processing means and the sequence processing means. Storage means for storing, selection means for selecting desired data from the numerical data stored in the storage means, and display means for displaying information on the data selected by the selection means. It is a feature.

In this manner, for a plurality of elevator operations, the status of permission / prohibition of execution of each operation, which operation is being executed, and which sequence is being executed for each operation are displayed in real time. This makes it possible to provide the operator with extremely useful information in a timely manner when checking the operation of the actual machine or dealing with a trouble.

This elevator operation control device comprises an operation processing device 1, a sequence processing device 2, a status display control device 3, a storage device 4 and a display device 5, and a communication device 6 and a remote maintenance terminal device 7 as required. Is added.

Here, the operation processing device 1 processes 100 or more types of operations in the elevator, processes the priorities of the operations, etc., and determines whether or not each operation is being executed.
Alternatively, it is in control of permission or prohibition of the execution of the operation. In the embodiment of the present invention, a case in which eight types of operations are controlled as shown in FIG. 2 will be described.

Therefore, each operation will be briefly described with reference to FIG. 2 showing a list of operations in the elevator. First, the inspection operation operation OP1 is an inspection operation that is started by turning on the inspection switch manually, and causes the elevator to run at a low speed for inspection. The earthquake control operation operation OP2 is an operation that is started when the sensor of the earthquake detector is turned on. At this time, the elevator car in operation is landed on the nearest floor, and the operation is stopped thereafter. The fire control operation operation OP3 is an operation that is started when the sensor of the fire detector is turned on. At this time, the elevator car in operation is operated directly to a predetermined evacuation floor, and the operation is stopped thereafter. is there.

Attendant operation operation OP4
Is an operation in which a driver rides in a car of an elevator and controls opening / closing of doors and call answering by operation of the driver. The over-riding prevention operation OP5 is an operation in which when the load in the car exceeds 110% of the rated load, an alarm buzzer on the car is sounded to open the door. The full-capacity automatic passage operation OP6 is an operation in which, when the load in the car exceeds 80% of the rated load, the vehicle passes a hall call on a floor without a car call. The mischief call cancel operation OP7 is an operation for deleting all car calls when the load in the car is less than 150 kg and the number of car call registrations becomes five or more. Normal operation O
P8 is a normal operation.

Among the above eight types of operations,
The inspection operation operation OP1 has the highest priority, and the seismic control operation operation OP2, the fire control operation operation OP3, and the attendant operation operation OP
The priority decreases in the order of 4, and normal operation O
P8 has the lowest priority. However, the overriding prevention operation OP5, the automatic packed passage operation OP6, and the prank call cancellation operation OP7 have the property of operating in parallel with other operations.

Next, the sequence processing device 2 controls the operation sequence of the actual operation in response to the execution decision of the priority processing and the like by the operation processing device 1, for example, a fire control operation operation OP3.
In this case, the operation OP3 is divided into seven types of states as shown in FIG.

That is, fire control operation operation O
The operation sequence during the execution of P3 is changed to the state ST immediately after startup.
0, a state ST1 that is stopped in addition to the evacuation floor, a state ST2 that is traveling in the direction opposite to the evacuation floor, and a state ST that is traveling in the direction of the evacuation floor
3. A state ST4 immediately before stopping on the evacuation floor, a state ST5 stopping on the evacuation floor, and a state ST6 not being executed are classified into seven types, and quantified as shown for each state. I have.

The status display control device 3 is provided with the aforementioned 8
Various types of data are stored and stored from an operation processing device 1 that controls the priority switching of the types of operations and a sequence processing device 2 that controls an operation sequence of an actual operation in response to an execution decision by the operation processing device 1. This is supplied to the device 4.

The status display control device 3 is determined as a result of the priority processing by the operation processing device 1.
An execution operation data storage unit 31 that creates execution operation data D1 represented by 8-bit numerical data based on a list of running operations A as illustrated in FIG. Have. Similarly, as shown in FIG. 4, based on a list B of execution-permitted and execution-prohibited operations determined as a result of the priority processing by the operation processing device 1, it is represented by 8-bit numerical data. It has a prohibited operation data storage unit 32 that creates prohibited operation data D2 and stores it in the storage device 4. Furthermore, the status display control device 3 has an operation status data storage unit 33 that converts the execution status of each operation in the sequence processing unit 2 into 8-bit numerical data of 00h to FFh and stores the converted data in the storage device 4. ing.

The execution operation data D1, the prohibited operation data D2, and the operation status data D3 to D10 stored in the storage device 4 are stored.
Display content switching controller 34 for selecting a desired one from among display data to be displayed on display device 5, execution operation data D1 and prohibited operation data D stored in storage device 4.
2, and operation state data D3 to D10,
A trace data storage unit 3 that sequentially stores the trace unit data D0 in the storage device 4 for each processing cycle.
5 is also provided in the status display control device 3. The trace unit data D0 is useful when a trouble occurs or when an operation operation is confirmed. FIG. 5 shows an example of the structure of the trace unit data D0. In this embodiment, the data has a 10-byte (80-bit) structure. Also, the operation state data D3 to D1
0 represents data corresponding to the eight types of operations shown in FIG.

A remote maintenance terminal device 6 is provided to check the contents of the storage device 4 from a maintenance management company or the like located far away from the installation location of the elevator and to perform maintenance and management of the elevator. Are connected to the storage device 4 via the communication device 7.

The operation of the thus configured elevator operation control device of the present invention will be described.

Assume that the execution of an operation at a certain point is in the state shown in FIG. That is, in FIG.
With respect to the operations OP1 to OP8, the operations being executed are displayed in the list A, the attendant operation operation OP4 indicated by a circle and the automatic passage operation OP6 indicated by a circle are being executed, and the others indicated by a cross are indicated. Indicates that the operation has not been performed. The operations whose execution is permitted are shown in List B, and the operations marked with a circle indicate that the execution is permitted. It has become.

The execution operation data storage unit 31 and the prohibited operation data storage unit 32 store the sequence from the inspection operation operation OP1 to the normal operation operation OP8 shown in FIG. 4 from bit position 0 to bit position 7 of 8-bit numerical data. Correspondingly, they are converted into execution operation data D1 and prohibited operation data D2. Accordingly, in the example shown in FIG. 4, the execution operation data D1 is 1 bit in the list of operations A being executed, where "O" indicates bit on and "x" indicates bit off.
The hexadecimal number is 28h (bits 3 and 5 are 1 and the others are 0), and the prohibited operation data D2 is 01h in the list of operations B in which execution is permitted, assuming that a bit is off and a cross is bit on. (Bit 0 becomes 1), and these numerical values are stored in the storage device 4.

Each data stored in the storage device 4 can be switched by operating the display content switching controller 34. The display content switching controller 34 includes a mode switching switch MS and an index switching switch IS shown in FIG. have. The mode change switch MS includes an execution display mode P1 indicating an operation being executed, a prohibition display mode P2 indicating an operation whose execution is prohibited,
And a mode to be displayed is selected from the three status display modes P3 indicating the status of the operation being executed. The index changeover switch IS designates an 8-bit numerical index number to be output to the display device 5.

In the embodiment of the present invention, when displaying the operation data D1 being executed, the mode change switch MS may be set to the execution display mode P1, and the index change switch IS may be set to the index 0 (I0). When displaying the operation data D2 whose execution is prohibited, the mode change switch MS is set to the prohibition display mode P2, and the index change switch I is set.
S may be set to index 0 (I0).

To display the status data of each operation, the mode switch MS is set to the status display mode P3 and the index switch IS
Should be matched with the index number of the operation for which you want to display. In the present embodiment, as shown in FIG.
(I0), the seismic control operation OP2 is assigned an index 1 (I1), and so on, and the normal operation OP8 corresponds to the index 7 (I7).

On the other hand, the operation state data is 00h
FFh are represented by numerical values, and it is possible to grasp which state in the operation is being executed by this numerical value. The operation state data when the operation is not executed is unified with FFh, and the operation state data that can be taken during execution is from 00h to FFh. As an example of such state data, FIG. 3 shows the contents of data (numerical values) corresponding to each operation state in the fire control operation operation OP3. That is, in the fire control operation operation OP3, when the fire detector is turned on, the fire is activated, the elevator is immediately made to go directly to the evacuation floor, and after landing on the evacuation floor, the operation is suspended (when the fire detector is turned off, normal operation is performed). Returning to operation), this series of operation sequence is shown in FIG.
As shown in the figure, the state 00 (ST0) to the state FF (ST
6), and by checking the operation state data, it is possible to grasp in real time which state the fire control operation is executing.

By the way, the operation data D1 being executed or the operation data D whose execution is prohibited
2. An 8-segment display 51 used for digital display of numbers as shown in FIG. 7, for example, as a display means for the operation status data D3 to D10.
Is available. That is, the determined output data is shown in FIG.
As shown in FIG. 7, based on the correspondence between the ON bit position and the lighting segment, some of the eight segments of segment 0 (S0) to segment 7 (S7) of the display 51 shown in FIG. .

For example, when the operation list A (execution operation data D1) shown in FIG. 4 is selected for output, the bits 3 and 5 are turned on, so that the segments 3 (S3) and 5 ( S
5) lights up. List of prohibited operations B
When (prohibited operation data D2) is selected for output, only bit 0 is on, so segment 0 (S0) of the display 51 is turned on.

Then, each operation state data D3
To D10 are output to the display 51, the attendant operation state data D6 and the full automatic passage state data D8
Are FFh (because they have not been executed).
0) to segment 7 (S7) are all turned on, and the attendant operation state data D6 and the automatic full passage state data D8 are numerical values corresponding to the progress of the operation sequence, and the display 51 corresponds to the numerical values. The lit segment lights up.

Next, another embodiment of the present invention shown in FIG. 9 will be described.

FIG. 9 is obtained by adding a start condition satisfaction operation data storage unit 36 to the system diagram shown in FIG. Therefore, the same parts as those in FIG. 1 are denoted by the same reference numerals, and the description thereof will be omitted.

The operation processing device 1 determines which of the eight types of operations shown in FIG. 2 is to be executed. At this time, the operation processor 1 checks whether or not the start condition of each operation is satisfied. I do. Each of the eight types of operations has a start condition. For example, the check operation operation OP1 is "check switch ON", and the fire control operation operation OP3 is "fire sensor sensor ON". Therefore, since the operation is executed when the start condition of each operation is satisfied and not prohibited, the start condition satisfied operation data storage unit 36 stores the result of checking the start condition of each operation in the operation processing device 1 as: It is stored in the storage device 4 as 8-bit numerical data similar to the execution operation data.

An operation whose execution is inhibited while the activation condition is satisfied can be easily obtained by calculating the logical product of the activation condition satisfaction operation data and the prohibited operation data stored in the storage device 4. In order to display, in real time, one of the prohibition operations obtained by this method, for which the activation condition is satisfied, the display content switching controller 34 shown in FIG. so,
The index changeover switch IS sets the index 1 (I
What is necessary is just to assign the time of 1).

An operation in which the start condition is satisfied, not prohibited, and not executed (an abnormal state that cannot be considered normally) is an operation that satisfies the start condition stored in the storage device 4. It can be easily obtained by taking the logical AND of the data, the execution operation data, and the prohibited operation data. In order to display the operation data obtained by this method in real time, the mode change switch MS of the display content change controller 34 may be assigned to the execution display mode P1, and the index change switch IS may be assigned to the index 1 (I1). .

In this way, since the relationship between the execution or prohibition of the operation and the establishment of the start condition can be grasped, an abnormality in the execution state of the operation can be easily detected.

It is needless to say that the present invention is not limited to the above-described embodiment, but can be carried out in various modifications without departing from the scope of the invention. For example, in this embodiment, since there are eight types of operations, a prohibited operation can be confirmed at a time on the display 51 having eight segments as shown in FIG. That is, the index changeover switch IS required to display the prohibited operation
Has only one contact point, the index 1 (I1) to
Index 7 (I7) can be used as another display selection contact, but this is not an absolute requirement. For example, the number of operations may be eight or more, and the use of the display including eight segments shown in FIG. 7 is only an example.
