BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test and evaluation device for an elevator, and more particularly to a group control device for an elevator that facilitates testing and evaluation work of a group control panel of an elevator.

Since elevators are industrial facilities that transport people, various tests must be conducted to ensure safety.In particular, elevator group control panels must be responsible for transporting complex detection personnel. After the evaluation, the feedback correction is performed and performance evaluation is performed again and again.

After this process, the actual number of modifications must be made in the operation process, and the group control panel is optimized as the test or performance evaluation is performed frequently.

Conventionally used elevator group drive control apparatus, as shown in Figure 1, the elevator group control panel 1 and each exhalation control panel 4 is a communication port (2) of the elevator group control panel (1) 1 to 1 by n to 1, and each exhalation control panel 4 is connected to an exhalation equivalent operation panel 5 which operates like an actual elevator by a control signal and a status signal line, A separate input / output terminal 3 is connected to the hall test operation panel 8 of each layer to receive a hall call button signal.

Also from each exhalation control panel 4, a car call input, a direction indication signal and a service allocation signal line of the corresponding floor are connected to the test operation panel 8.

Referring to the operation and problems of the conventional elevator device in detail as follows.

First, when a hall call occurs under a specific situation, a call to be serviced is assigned by a control algorithm in the elevator group control panel 1, and in order to produce a specific situation, the hall call switch 8-1 of the test control panel 8 is used. It must be operated several times.

For example, in FIG. 2, the elevator belonging to the elevator group control panel 1 that controls six units is located uphill on the fourth floor, the second on the first floor, and the third on the first floor. Descending from the floor… In the case of 7-hole call (up) (a), if the service assigned to test and performance analysis, connect the configuration of Fig. 1 and each of the exhalation control panel (4) and the exhalation equivalent operation panel (5) After confirming the normal operation and confirming the connection of the I / O terminal 3 of the elevator group control panel 1, press the 4th floor hall button of Unit 1 and the 8th floor button of Unit 3 to produce a specific situation. Make an ascending call on the seventh floor to visually check the operation and service results.

However, when the device is to test the elevator group control panel (1), the preliminary work is too much because it must be carried out after connecting a large amount of devices and electronic equipment to check the normal operation.

In addition, since the situation is created by operating the switch of the test control panel 8, it is necessary to proceed with a test and evaluation of performance different from the actual situation in which the elevator is operated depending on time and conditions, and thus the limited test and performance evaluation results can be expected. There is only a problem.

Accordingly, an object of the present invention is to solve the coupling according to the conventional elevator operation system as described above, to solve the inconvenience of pre-installing a large amount of test equipment and to create a situation of traffic flow similar to the actual operation situation and test and Therefore, to provide a new elevator group control method that can significantly improve the experiment and performance evaluation of the elevator group control panel.

3 is a block diagram of a simulator for an elevator apparatus according to the present invention. As shown in FIG. 3, a simulator operation control panel 11, N unit equivalent control panels 10, and a traffic flow generating device 12 are illustrated. Exhalation equivalent control panel 10 is coupled to the independent elevator group control panel 1, the traffic flow generating device 12 is configured to communicate with the elevator group control panel 1 through a separate communication port (13). In addition, the traffic flow generation device 12 comprises N traffic flow data files by filing data such as the number of Hall calls and car calls according to time by mode such as a work mode or a work mode. do.

The operation and effects of the elevator group control system of the present invention configured as described above are described in detail.

In FIG. 3, the operation control panel 11 of the elevator group control panel simulator is a collection of computer hardware and software, which monitors the operating state of the elevator group control panel 1 on the screen of a computer and prepares the result in a graph or various diagrams to make it hard. It also writes to disk and prints out as needed. That is, the operation state of each individual unit obtains the group control display state, the door open / closed state, and which floor of the building are operated from the exhalation dynamics control panel 10 and displays it graphically on the color monitor screen of the computer. . In addition, before the generated hall call is obtained from the elevator group control panel 1 and assigned, it can be marked at the position of (a) in FIG. 2 to observe which unit is being served. In addition, as a result of the service of Holbrum or Kaburum, it is possible to monitor which plane was stopped on which floor and how many passengers were boarded on the color monitor screen. To display all the movements of the actual screen as a result of the operation, since there is too much data, the minimum data for performance analysis is extracted and stored in the traffic flow generator 12 as N traffic flow data files. For example, the number of calls generated over time is not included in the analysis data record, and it is not included in the analysis data record, but it is a graph showing the movement of the elevator over time, the number of ascents of the elevator, the total number of passengers carried, the time of travel, The filed travel distance and the like in a tabular format is stored in the traffic flow generating device (12).

Therefore, at the start of the group control panel simulator, the operator inputs the control for selecting the traffic flow data of the traffic flow generator 12 through the keyboard of the simulator operation control panel 11 and initializes it.

When the test and performance evaluation are started, the corresponding traffic data file is read by the traffic flow generator 12 according to the simulation mode and the simulation time input through the keyboard or the like, and the traffic flow is generated to lift the elevator through the communication port 13 of the simulator. It transmits to the group control panel 1.

The received information is selected according to the algorithm and parameters of the elevator group control panel 1 and assigned to the equivalent control panel 10 of the corresponding unit through the communication ports 2 and 9 of the corresponding unit. That is, when a call is assigned to a call, a call corresponding to a call that is serviced by the serviced call is generated, which is immediately changed to a call after the call is served.

The equivalent Zeaban 10 of the assigned breathing service services the assigned call through a simulation such as the movement of the elevator and reports the status and result to the elevator group control panel 1 through the communication port 9 continuously, The simulation state of the equivalent control panel 10 itself is always sent to the state assigned to the operation control panel 1.

To simulate the test situation in FIG. 2, the traffic flow data should be the same as the situation in FIG. 2 a certain time before the seventh ascending call occurs, and the signal can be generated at the desired time.

Compared with the operation of the test control panel 8 of FIG. 1, a much more precise and accurate test is possible, and statistical analysis of the driving results recorded and stored in the operation control panel 11 of the simulator is performed to analyze the algorithms and parameters of the group control panel. It can be optimized by simulation.

Meanwhile, the control flow of the exhalation equivalent control panel 10 under the control of the elevator group control panel 1 will be described in detail based on the flowchart of FIG. 4.

First, a special operation is performed by receiving a command from the group control panel 1, and a special operation is performed. If there is a newly assigned hall call, the call is registered. Investigate this to perform a hall call service and generate a call for each new passenger. If the call is the closest call, perform a call service and then release the call.

However, if there is no calling, a standby operation for the reference floor is performed and the elapsed time is checked without calling, and when the time elapses for a predetermined time, power saving standby is entered.

5 is a control flow diagram for the traffic flow generating device 12. As shown in FIG. 5, the simulation time and mode are input, the traffic flow data file is selected according to the situation, and the traffic flow is selected based on the data of the selected file over time. Enter the manual data of the special situation test and send it to the elevator group control panel.

As described above, the present invention almost eliminates the preparation time by connecting only the simulator and the communication port without installing a large apparatus and electronic device for preparation when testing and evaluating the group control panel. As a result, the test and performance evaluation are almost the same as the actual situation, and the optimization process can be carried out immediately by modifying the traffic flow data or modifying the operating parameters of the group control panel by reflecting the simulation results. There is an effect that can significantly shorten the application time.
