Description of the Prior Art
Referring to Fig. 1, there is shown a block diagram of a conventional group management control apparatus for elevators.
As shown in this drawing, the conventional group management control apparatus comprises a plurality of hall call buttons 21-4n disposed in each of the elevators. Each of the hall call buttons 21-2n is disposed every floor to output a hall call signal when it is pushed by the user.
The conventional group management control apparatus also comprises a plurality of control boards il-ln, each of which controls a running state of a corresponding one of the elevators and outputs information regarding the running state of the corresponding elevator through a serial data transmission line.
Also, the conventional group management control apparatus comprises a group management control section 10 for outputting a control signal to a selected one of the control boards 11-in through the serial data transmission line in response to the hall call signal from a pushed one of the hall call buttons 21-2n and based on the elevator running state information from the control boards 11-1n, to operate the optimum elevator in which a waiting time of the user is shortest.
The operation of the conventional group management control apparatus with the above-mentioned construction will hereinafter be described.
First, when the user pushes one of the hall call buttons 21-2n disposed on a floor on which he is present, the hall call signal from the pushed hall call button is applied to the group management control section 10. In response to the hall call signal from the pushed hall call button, the group management control section 10 outputs the control signal through the serial data transmission line to one of the 1st to nth elevator control boards 11-ln corresponding to the optimum elevator in which the waiting time of the user is shortest.
This is performed on the basis of a pre-stored hall call allocation algorithm which is carried out based on the elevator running state information which are supplied from the 1st to nth elevator control boards 11-in to the group management control section 10 through the serial data transmission line.
The elevator running state information from the 1st to nth elevator control boards ll-ln may include, for example, an elevator position, an elevator direction, a door state, a cage weight, a car call and etc.. Based on such elevator running state information from the 1st to nth elevator control boards ll-ln and in response to the hall call signal from the pushed hall call button, the group management control section 10 outputs the control signal through the serial data transmission line to one of the 1st to nth elevator control boards 11-ln corresponding to the optimum elevator in which the waiting time of the user is shortest. Then, in response to the control signal from the group management control section 10, the corresponding control board operates the corresponding elevator to run to the floor in which the hall call signal is venerated.
However, the conventional group management control apparatus has a disadvantage in that the elevator running state information supplied to the group management control section can not ssrntheticalls be discriminated in a machine room since they are not supplied to the machine room. Also,
t is impossible to initialize the control signal from the group management control section in response to the hall call signal in an elevator test running. Further, in the case where an engineer intends to test a performance of a program for the control of the running states of the elevators, he must analyze and estimate the elevator running state information by hand for a long time in the field, with a difficulty.

When the user pushes one of the hall call buttons 71-7n disposed on a floor on which he is present, the hall call signal from the pushed hall call button is applied to the group management control section 50. In response to the hall call signal from the pushed hall call button, the group management control section 50 outputs the control signal through the serial data transmission line to one of the 1st to nth elevator control boards 61-6n corresponding to the optimum elevator in which the waiting time of the user is shortest, on the basis of a pre-stored hall call allocation algorithm which is carried out based on the elevator running state information which are supplied from the 1st to nth elevator control boards 61-6n to the group management control section 50 through the serial data transmission line.
For example, the elevator running state information from the 1st to nth elevator control boards 61-6n may include an elevator position, an elevator direction, a door state, a cage weight, a car call and etc.. Based on such elevator running state information from the 1st to nth elevator control boards 61-ôn and in response to the hail call signal from the pushed hall call button, the group management control section 50 outputs the control signal through the serial data transmission line to one of the 1st to nth elevator control boards 61-6n correspond in to the optimum elevator in which the waiting time of the user is shortest.Then, in response to the control signal from the group management control section 50, the corresponding control board operates the corresponding elevator to run to the floor in which the hall call signal is generated.
On the other hand, transferred to the group management diagnostic section 80 are the elevator running state information from the 1st to nth elevator control boards 61-6n and the control signal from the group management control section 50.
Namely, the communication unit 81 outputs the request signal to the group management control section 50 to request the group management control section 50 to transfer the control signal from the group management control section DO and the elevator running state information from the control boards 61-6n thereto for the predetermined time period. As a result, the communication unit 81 receives the control signal and the elevator running state information which are transferred by the group management control section 50 for the predetermined time period in response to the request signal.
The control signal and the elevator running state information received by the communication unit 81 are iispi.l-ed on the screen b the display processing circuit 82 under the control of the control unit 85.
The elevator running state information collector 83 acts under the control of the control unit 85 to instruct the communication unit 81 to receive the elevator running state information from the control boards 61-6n for the predetermined time period.
The elevator running performance analyzer 84 acts under the control of the control unit 85 to analyze the elevator running state information which are received by the communication unit 81 under the instruction of the elevator running state information collector 83. The analyzed result is converted into data to be displayed on the screen by the display processing circuit 82. As a result, the converted data is displayed on the screen.
Fig. 4 is a flowchart illustrating the operation of the group management control apparatus in Fig. 2 in accordance with the present invention. Upon powering the group management control apparatus, the control unit 85 initializes the components in the group management diagnostic section 80.
Then, the current time and menus are displayed on the screen by the display processing circuit 82 in the group management diagnostic section 80 and one of the displayed menus selected by the user is processed bv sub-programs. For example, in the case where the user intends to monitor test running stales of the elevators, a sub-program of collecting the elevator running state information, a sub-program of analyzing the performances of the eLevators on the basis of the collected elevator running state information, a sub program of displaying the analyzed result, and etc. are performed. These sub-programs are repeatedly performed until completion.
As apparent from the above description, according to the present invention, the control signal regarding the selected one of the 1st to nth elevator control boards and the elevator running state information from the 1st to nth elevator control boards are transferred to the group management diagnostic section by the group management control section. Therefore, the running states of the elevators can synthetically be discriminated in the machine room. Also, it is possible to initialize the control signal from the group management control section in response to the hall call signal in the elevator test running. Further, the performance of the program for the control of the running states of the elevators can readily be tested.
