BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for efficiently serving a call registration in two independent elevators, in particular, when a call registration occurs for two elevators at the same time, a passenger call flicker change table is used to The present invention relates to an operation control method of an elevator so as to be suitable for indicating whether the elevator can be serviced quickly.

When a plurality of elevators are operated, the hall calling configuration of the elevator is configured as two independent hall calling methods as shown in the first diagram or two parallel hall calling methods as shown in the second diagram.

3 is an operation control block diagram of a general elevator composed of two independent hall calling methods. As shown in FIG. 3, the central control unit 11 collectively controls the operation of the elevator in response to a call registered on the call registration unit 15. And a memory 12 in which various operation control programs and calling registrations are stored, an input device 13 for registering a calling according to a button selected on the calling registration unit 15, and to indicate that the calling is registered. An output device 14 for turning on a lamp corresponding to the button selected on the call register 15, and a call register 15 installed on the hoistway of each floor of the elevator to accept the call registration selected by the passenger and to display that the call is selected. The operation of the conventional elevator configured as described above will be described with reference to FIGS. 4 and 5 as follows.

When the passenger presses the up or down button provided on the call register 15 at the hall side, the corresponding button signal is transmitted to the central controller 11 through the input device 13 and the memory 12. Accordingly, the central control unit 11 recognizes which hall button is pressed based on the button signal, and then lights a lamp corresponding to the button pressed on the call register 15 through the output device 14. Let's go.

The above description will be described in more detail with reference to the task flow chart of FIG. 5, which is a routine for checking whether a call is registered at a certain period (for example, 40MS). Check and register the check result in the rising or falling calling area of the memory 12 as shown in (a) of FIG. 5, and the lamp output signal in the corresponding rising or falling lamp output area as shown in (b) of FIG. By storing the operation of the elevator is called.

However, in such a conventional operation control device, when the time is tight as in an apartment in the time zone, the upper button of the elevator is considered to be close to move to the reference floor. When there is a lot of floor calls, the passengers will be able to service other elevators faster, so the passengers press the call button of the other elevators. Even if the service is serviced by another elevator on the floor, another elevator serviced again on the serviced floor, there was a defect that the operating efficiency of the elevator is lowered.

In order to solve such a defect, the present invention calculates the desired number of calls using the hole call flicker change table, and based on the result, it is possible to flicker the hall lamp of the corresponding floor by grasping which unit can quickly service. The invention is described in detail with reference to the accompanying drawings.

6 is a control block diagram of an elevator to which the operation control method of the present invention is applied, and as shown in FIG. 6, a central control device 11 which controls the operation of the elevator collectively in response to a call registered on the call register 15. In order to indicate that the memory 12 stores various operation control programs and calling registrations, the input device 13 for registering the callings according to a button selected on the calling registration unit 15, and the callings are registered. An output device 14 for turning on the lamp corresponding to the button selected on (15), a call register 15 installed on the hoistway of each floor of the elevator to accept the call registration selected by the passenger, and to display that the call is selected; It is composed of the input control device 16 for setting a time zone that uses a lot of elevators such as when going to work or going to work. The operation and effects of the present invention will be described in detail with reference to FIGS. 7 to 10 as follows.

When the passenger presses the up or down button provided on the call register 15 at the hall side, the corresponding button signal is transmitted to the central controller 11 through the input device 13 and the memory 12. Accordingly, the central control unit 11 recognizes which hall button is pressed based on the button signal, and then lights the lamp corresponding to the button pressed on the call register 15 through the output device 14. do.

By the way, if the input control device 16 does not set the time of using the elevator relatively much, such as the time of going to work or the time of leaving work, the lamp corresponding to the pressed call registration switch is turned on as in the prior art, and if it is set, the service is called sooner. The call registration lamp on the elevator side can be displayed blinking so that the passenger can recognize it, and the process thereof will be described in more detail with reference to FIG. 10.

The task flow cycle is assumed to be 40MS, and it is determined whether the rising call or the falling call is registered in hardware and stored in the rising or falling area of the memory 12 (S1-S4), and input through a switch or various input devices. It is checked whether a predetermined time (for example, time to leave and leave the office) is set in the controller 16, and if it is not set, the operation is controlled to service the call registration as in the normal method.

However, if the predetermined time is set in the input / output control device 16 as a result of the above confirmation, it corresponds to the floor set arbitrarily (for example, 2nd floor-top floor-3rd floor) (S6, S7), and the current elevator position is that floor. Make sure you are above (S8).

The floor on which the elevator is located is called the sync floor, and when the floor corresponding to K is smaller than the sync floor, the K floor is subtracted from the sync floor and placed in K1 (the number of floors that can be serviced from the elevator location to the K floor) (S9). Below, the number of falling calls to the K floor is set to K2 (S10), and K1 / K2 is calculated to find K3. (S11)

If the obtained K3 is greater than a certain value Q (assuming 3) (S12), if it is not large, that is, if the number of calls is 1/3 or more, the hollamp is not flickered; In the case of less than 1/3 of the calling, the calling lamp of the floor is flickered.

After that, to ensure that the lamp on the registered floor continues to be set, it is checked whether the button on the K floor is set (S13), and if it is set, the count value (COUNT) is reset (S14). Increase the count value (COUNT) by one (S15), check if the predetermined count bit (Bit 3) is set (S16), and if it is not set, reset the corresponding lamp output on the K-floor and set the K value if it is set. After increasing by one (S19), the process returns to the seventh step S7.

In other words, the number of hall descending calls from the synchronous layer to an arbitrary K layer is calculated to enable flicker by the FIG. 9 hole call flicker change table, and the call is registered to confirm that the lamp is continuously set. If it is not, the counter is incremented so that the corresponding lamp output flickers for the corresponding K layer every certain period (eg 320MS).

As described above, when the input control apparatus is set, the serviceable floor number K and the hole descending floor number K2 from any K floor to the sync floor are calculated, and FIG. 9 shows the hole call flicker changing table. By flickering the hall down ramp, passengers will be able to identify which units are available for faster service.

As described in detail above, in the system in which two elevators are operated alone, the elevator can provide convenience to passengers by indicating which elevator can service faster through a button lamp on the hall side. There is an effect that can improve the operating efficiency.
