In addition, the machine control microcomputers E1 to E are equipped with car call information necessary for control, car load change information at each floor, and control power elements consisting of various elevator safety limit switches, relays, and response lamps. EIOz~EIO, and the circuit PIA that inputs and outputs signals in parallel with the signal #! 5I01～
Connected via 5Ion.

The present invention will be explained in detail using FIG.

The microcomputer M1 has a built-in operation control program mainly for call assignment, and this operation control program takes in information necessary for control from the microcomputers E1 to En for controlling each machine and the hall call HC. Further, the operation control program performs call assignment using variable parameters. For example, this parameter includes the area priority parameter, which is a weighting coefficient that indicates the relationship between the waiting time in the call assignment evaluation function and the evaluation value of power consumption, the door opening/closing time control parameter, which determines the door opening/closing time, and the door opening/closing time control parameter, which determines the door opening/closing time. There are fullness prediction parameters for preventive control, stop probability parameters for accurately predicting the time required for an elevator to arrive at the floor where a hall call occurs, and service priority level parameters for preferentially servicing crowded floors.

These variable parameters are set by the microcontrollers E1 to E for each machine.
Calculated by inputting the information on the number of passengers getting on and off each floor on each floor obtained from n and the command PC of the setting device PD to the group management control simulation program built into the microcomputer M2, the elevator group management is optimized for the traffic volume in the building. It allows driving.

On the other hand, the microcomputer M2 mainly processes three functions: a function of collecting and accumulating the traffic volume in the building, a function of simulating group management control, and a function of displaying elevator service performance, traffic demand, etc.

First of all, the function of collecting and accumulating the traffic volume within a building is based on the essential traffic volume unique to each building, as the traffic volume within the building varies depending on the day and there are floors where events are held depending on the time of day. Because noise unique to that day is added to the traffic flow, it is necessary to remove this noise in order to learn the essential traffic volume. However, the problem of understanding the essential traffic volume specific to a building is difficult because the traffic volume of a building also has the problem that the essential traffic volume changes due to changes in the building over time, that is, structural changes and tenant changes. The problem cannot be solved simply by removing changes in traffic volume.

The present invention does not solve this problem but relates to a display device, so a detailed method will not be described. This section describes in detail the means for displaying statistics such as traffic flow conditions, variable parameters optimal for elevator operation, and elevator service performance.

Next, the function to simulate the first group management control is to calculate the average waiting time when driving is controlled based on the optimal variable parameters to achieve the target value input from the traffic volume and setting device PD, and each parameter. This function calculates service performance such as power consumption value and creates display data.

Furthermore, the function of displaying elevator service performance, traffic demand, etc. allows building managers and the like to understand the performance of the entire elevator system and the traffic situation. This situation can be displayed as required using the keyboard KEY and display DSP of device M3.

Next, the specific hardware configuration of each microcomputer will be shown, but these microcomputers can be easily configured as shown in FIGS. 2 to 4. MP, the center of the microcomputer

In FIG. 3, the setting device PD is a setting volume VR.
It is composed of an A/D converter that converts the analog output voltage of this VR into a digital value, and this output PC is
Loaded into RAM from A. Further, the SDA connected to the microcomputer M2 is for reception only, and only the reception line RX is connected thereto.

FIG. 4 is a hardware configuration diagram of the display device M3.

The serial communication processor ACIA is connected to the Mycosi M2, and has the function of receiving display data, that is, elevator service performance values and traffic data, and outputting a transfer request signal for the data necessary for display. . The microcontroller MPVI is used for communication-only processing, and has the function of transferring received data from the internal register of ACIA to Tx/RxBf, which is a RAM for temporary data storage, and interpreting display request signals input from the keyboard to display content. Function to inform display-only microcomputer MPV and Tx/RxB
There is a function to transfer the contents of f to Seg-Bf, which is a RAM for graphic registration. On the other hand, the microcomputer MPV is a display-only microcomputer that enables high-speed display. In addition, if most of the displayed figures or characters are predetermined, you can register only the basic figures in the Seg-BF of the figure registration RAM and rewrite only the changed parts via MPVI. can easily be displayed at high speed simply by transferring the contents of Seg-Bf to 5cQ-Bf of the display RAM.

A display device having such a system configuration is, for example, the graphic display device GR-340 made by Daini Seiko Kin.
There is a first prize.

Although this display device is a display device, it may also be a device that prints on paper, such as a line printer.

Next, a software configuration according to an embodiment of the present invention will be described. First, the overall software configuration will be explained with reference to FIG.

As shown in Fig. 5, the software can be roughly divided into an operation control program, a group management simulation program, and a display program, which are microcontrollers Ml, M2, and M2, respectively.
and is processed by the display-only microcomputer MPV.

The operation control program is a program that directly instructs and controls elevator group management control such as call assignment processing and elevator distributed standby processing.

Elevator control table SFI and hall call table SF including elevator position, direction, car call, etc. sent from the machine control program as input to this program
2. Elevator specification table 5F13 including number of managed elevators, etc. and optimal operation control parameter table 5F
The input data is 12th grade.

The group management simulation program inputs the in-building traffic volume learning table SF6 and the preset area priority parameter table SF7, and performs an elevator group management simulation for a predetermined period of time under the preset area priority parameters to calculate the average waiting time, This is a program that calculates the longevity rate, power consumption value, fullness prediction parameter, stop probability parameter, service priority level parameter, door opening/closing time control parameter, etc. The output results become display data.

The display program includes the building traffic data table SF4 which is the current traffic volume in the building, the building traffic learning table SF6 which is the learned essential traffic volume of the building, the simulation table SF9 which is the result of this simulation, and the building traffic volume data table SF4 which is the current traffic volume in the building. Target value table 5FIO set by administrator
1. This program takes as input an optimal operation control parameter table 5F12 that stores optimal operation control parameters, and a display control table 5F15 that selects and controls a display screen, and outputs a screen to the display table.

Figure 6 is a table configuration diagram of the current in-building traffic data table SF4, which is display data.The data is collected by floor, direction, number of people getting on, and number of people getting off, and the average is calculated directly from the actual elevator service status. It consists of statistics calculated by collecting data such as waiting time, average hall call duration, long retention rate (560 seconds), and number of distributed waiting times.

FIG. 7 is a configuration diagram of the in-building traffic learning table SF6, which is the essential traffic of the building, and has the same format structure as the traffic data in the in-building traffic data table SF4 shown in FIG.

FIG. 8 shows a simulation table SF9 that stores the output results of the group management simulation program, a target value table 5FIO that stores target values set by the building manager, and an optimal value determined from the simulation results and target values. It is a configuration diagram of an optimal operation control parameter table 5F12 that stores control parameters. Here, the current in-building traffic data table SF in Figure 6 is
4 and the simulation table SF9, the elevator service performance evaluation before and after execution of the group management control can be displayed, thereby making it possible to grasp the control situation.

FIG. 9 is a table configuration diagram of a display control table 5F15 that controls the screen displayed on the display device and a display table 5F17 that stores the contents to be actually displayed.

10 to 19 are examples of the flow of a display program and display screens. This program determines what to display according to the control information 5F15 input from the keyboard, registers the basic figure shown in FIG.
This is a program that transfers the contents of f to 5cQ-Bf for display.

FIG. 10 is a program flow for displaying the number of people getting on and off the elevator. The number of people getting on and off the elevator is based on the current number of people getting on and off the elevator in the building and the learned number of people getting on and off the elevator.

First, in step AIO, display control table 5F15
It is determined whether the display detection flag requests display of the number of people getting on and off the elevator. Step A20
Now, the basic screen for displaying the number of people getting on and off the elevator is transferred from the basic figure registration memory Seg-Bf in FIG. 4 to the display memory ScQ-Bf. In step A30,
It is determined whether the flag for the number of people getting on and off the elevator in the display control table 5F15 indicates the current building traffic volume or the learned traffic volume.

In step A40, if the data to be displayed in step A30 is the learned traffic volume, the data in the in-building traffic volume learning table SF6 is transferred to the display tables 5aQ-Bf. In step A50, if the content to be displayed in step A30 is the current number of people getting on and off the elevator, the data in the building traffic data table SF4 is transferred to the display table 5cfl-Bf. As a result, information requested from the keyboard can be displayed on the screen. For example, the first
As shown in Figure 1, if you display the number of people getting on and off the elevator, you can compare the number of people getting on and off the elevator on which floor and in which direction, or the number of people getting on and off the elevator, compared to the standard value drawn by the dotted line, or the characteristic of the entire building. You can clearly understand the movements.

FIG. 12 is a program for broadly classifying and displaying the elevator bank traffic volume. Moreover, FIG. 13 is an example of a display drawing.

The program flow shown in FIG. 12 will be explained.

In step BIO, it is determined whether the display detection flag of the display iiJ control table 5F15 requests display of elevator bank traffic. If not, the process ends, and if so, step B20 is processed.

Step B20 is a basic figure '1D memory Seg-B.
The basic figure of elevator bank traffic is transferred from f to display table 5cQ-Bf which is a display memory. In step B30, whether the elevator bank traffic flag in the 1-display control table requests information on the in-building traffic learning data or requests information on the elevator bank traffic of the current in-building traffic. is being determined. In step B40, if the learned traffic volume is requested, the learned traffic volume in the table SF4 is aggregated. In step B50, if the current traffic volume is requested in the determination in step B30, the current traffic volume in table SF4 is aggregated. Step B
60 is a process of transferring the aggregation processing results to the display table. The elevator bank traffic volume can now be displayed. On the other hand, in the example of the drawing in FIG. 13, the usage status of the elevator bank is generally congested, or
It is displayed so that you can easily tell if it is quiet. It also has the feature of being able to tell what type of traffic flow is common.

FIG. 14 is a program flow for displaying target values set by the building manager.

In step CIO, it is determined whether the display detection flag in the display control table requests display of the target value. In step C20, the basic figure for displaying the target value is stored in the basic figure registration memory Seg-Bf in FIG.
The display table (Se2/Bf
).

In step C30, it is determined whether the target value is the average waiting time or something else, and if it is the average waiting time,
In step C40, only the display range of the average waiting time is displayed in red. If it is determined in step C30 that the target value is not the average waiting time, it is determined in step C50 whether the target value is the long life rate, and if so, only the display range of the long life rate is displayed in red in step C60. If it is determined in step C50 that the target value is not the long life rate, the target value is understood to be the energy saving rate, so the range of the energy saving rate is displayed in red in step C70. In step C80, the contents of the target value table are transferred to the display table (ScI2.Bf).

The display of the target value is finished above, but if the target value is set to, for example, an average waiting time of 20 seconds based on the simulation data, both the longevity rate and the power consumption value can be uniquely determined. For this reason, it is possible to know the values between the target values for the longevity rate and power consumption value by displaying the simulation results, so it is important to note that, for example, it is possible to reduce the longevity rate and achieve energy-saving operation. It is the right thing to do.

FIG. 15 is an example of target value display.

In the display example of FIG. 15, since the long life rate is set as the target value, the range of the long life rate is displayed in a special color.

FIG. 16 is a program flow for displaying elevator system performance.

Elevator system performance can be displayed by displaying the performance of actual elevator operation, such as the average waiting time for the current building traffic, which is stored in the building traffic data table SF4, and a simulation table. There is a performance display that is calculated by simulation of the traffic volume that was memorized and learned during SFQ.

First, in step DIO, it is determined whether the display detection flag in the display control table requests display of elevator system performance. In step D20, the basic figure of elevator system performance is transferred from the basic figure registration memory Seg-Bf to the display table, which is a display memory.

In step D30, it is determined whether the displayed content is a simulation result display or a performance display as a result of actual elevator operation. if.

If performance display of the simulation results is requested, in step D40, the simulation table SF
Displaying elevator performance data during Q Table 5cQ-B
Transfer to f. If performance display as a result of actual elevator operation is requested in step D30, the elevator system performance data in the in-building traffic data table SF4 is transferred to the display table in step D50. FIG. 17 is an example of a display diagram of elevator system performance. The dashed circle indicates standard elevator performance. The solid line shows the performance of the elevator system. For example, the average elevator running time is two hours, which is greater than the standard value broken line.

This indicates that power consumption is large. The characteristic of the display diagram of FIG. 17 is that the performance balance of the entire elevator system can be seen at a glance.

FIG. 18 is a program flow for displaying control parameters. The control parameters include area priority parameters, fullness prediction parameters, and stop probability parameters.

If only the parameters were displayed on the car, the amount of displayed information would be extremely small, and its meaning would be unclear. Therefore, we devised a display method in which the effects of the control parameters can be understood by displaying the relationship between the control parameters and the average waiting time, longevity rate, and power consumption value in the same drawing as shown in FIG. 19.

The program shown in FIG. 18 will be explained.

In step E10, it is determined whether the display detection flag in the display control table requests display of control parameters. In step E20, a basic figure for displaying control parameters and Seg-Bf are selected and transferred to a display table which is a display memory. In step E30, the optimum operation control parameters for actually operating the elevator are displayed in the control parameters, or
Alternatively, it is determined whether to display the control parameters of the simulation results. If the simulation results are to be displayed, in step E40, the control parameters stored in the simulation table SFQ are transferred to the display tables ScQ and Bf.

If the optimum operation control parameters are to be displayed, the optimum operation control parameter table 5 is displayed in step E50.
The control parameters, average waiting time, long life rate, and power consumption value during F12 are transferred to the display table.

FIG. 19 is an example of a display drawing of control parameters. Here, the average waiting time direction mWT, long duration curve LT, and power consumption value curve DP with respect to changes in the area priority parameter are shown. By displaying in this manner, it is possible to grasp the change in power consumption value at the same time as the change in elevator performance with respect to the control parameter, so the effect of the control parameter can be immediately understood.

Although the area priority parameter is used in the display drawing example of FIG. 19, it is also possible to display other parameters on the horizontal axis and the service performance curve and power consumption value curve on the vertical axis.

A group management control device with a traffic collection function can improve elevator system performance by displaying not only the current in-building traffic volume and learned traffic volume, but also statistics such as elevator service performance and energy conservation. We have shown that a display device that displays the balance of performance can be easily realized by applying a commercially available display device.

In addition, the explanation has been given using a display device as an example of a display device, but similarly, the performance balance of an elevator system can be easily printed using a device that prints on paper, such as a commercially available line printer. .

By displaying a display diagram of the number of people getting on and off the elevator, elevator service performance, and power consumption values, as well as the target values set by the building manager, it is possible to detect defects in the group management control program and energy saving program. Also,
Bad results can be displayed.

Furthermore, by displaying the group management control parameters and the elevator service performance and power consumption values on the same drawing, it is possible to understand the effects of the control parameters.

According to this embodiment, by displaying not only the current traffic volume but also the learned traffic volume, which is the essential traffic volume of the building, on a diagram, it is possible to easily grasp the balance of the current elevator usage status.

By displaying the elevator service performance, power consumption value, etc. on the same drawing, the balance of elevator performance can be easily understood.

According to the present invention, the usage status of the elevator can be easily grasped by displaying the number of people getting on and off the elevator, etc., which is not available in conventional group management control devices.
