Description

  The present invention relates to a display control apparatus for a renewal elevator in which each display in an existing elevator system is changed to a digital dot matrix display.

  As is well known, in an elevator control apparatus, as with general electronic control equipment, with the advancement of semiconductor technology, a large number of microcomputers have been adopted, and improvement in performance and miniaturization are achieved.

  When this microcomputer began to be used in elevators, it was used only in the main control unit housed in the elevator's machine room, and the display signal from the main control unit to the display on the hall control panel in the elevator hall on each floor In addition, the hall call buttons were controlled, and the display signals and the car call buttons for the car display on the car control panel provided in the elevator car were controlled.

  However, with the advancement of semiconductor technology, a microcomputer is also introduced into the car control board and the hall control board, so that communication between the main controller and the hall control board and between the main controller and the car control board is possible. As a result, the number of wires in the hoistway and the number of wires in the tail cord have been reduced.

  As shown in FIGS. 11 (a) and 11 (c), the car position display method in the conventional car control panel or hall control panel is generally arranged next to the LED lighting position by shifting the lighting position of the dot LED. A method of indicating numbers of car positions with acrylic or the like, that is, a dot LED lighting type display 1 has been adopted. Further, as shown in FIG. 13, a method of displaying the floor of an elevator with 16 digits of LED 2 digits using 16 to 23 display signals, that is, a 16 segment LED lighting display 2 has been mainstream.

  However, by incorporating a microcomputer in each hall control panel or car control panel, as shown in FIG. 15, in recent years, LEDs are arranged in a dot matrix and the corresponding LEDs are turned on to display the elevator floor. The method, that is, the digital dot matrix LED display 3 has become mainstream.

  FIG. 10 shows a configuration diagram of an existing elevator system in which a microcomputer is introduced only in the main controller and a dot LED lighting type display is adopted for each display.

  A hoisting machine 8 that is rotated by an electric motor 7 is installed in a machine room 6 above the hoistway 5 in which the elevator car 4 moves up and down, and the car 4 and the counterweight 9 are attached to both ends of the hoisting machine 8. The main rope 10 is hung. The electric motor 7 is rotationally controlled by a drive circuit 12 using an alternating current supplied from an alternating current power supply 11. In the machine room 6, in addition to the hoisting machine 8, a main control panel 15 containing a main control device 13 and an input / output circuit 14 in which a microcomputer is incorporated is installed.

  A car control panel 16 is mounted in the car 4. The car control panel 16 has the dot LED lighting display 1 shown in FIG. 11A and the car call button shown in FIG. 17 is provided. In this example, as shown in FIG. 11 (a), since the service floor of this elevator is the 1st to 4th floor, in the dot LED lighting display 1, a total of 6 including the destinations of the upper and lower cars 4 are included. Each LED 18 is covered with an acrylic cover on which a number representing a car position is written.

  Accordingly, the dot LED lighting display 1 is controlled to be lighted by the six signal lines 19 from the main controller 13 via the input / output circuit 14. In the car call button 17, four push buttons 20 on the first to fourth floors are provided as shown in FIG. 11 (b), and the main control device is connected to the four signal lines 21 via the input / output circuit 14.

The lighting is controlled by six signal lines 25 through 14. In the hall call button 24, two upper and lower push buttons 20 are provided, and a hall call signal is sent to the main controller 13 through the input / output circuit 14 through the two signal lines 26.

  As the main controller 13, an 8-bit to 32-bit CPU is generally used. The input / output circuit 14 is a circuit necessary for communicating signals from the main control device 13 to the outside. The input / output circuit 14 converts a DC5V parallel display signal from the main control device 13 into a DC24V parallel display signal. The signal is transmitted to the dot LED lighting type indicators 1 and 23 via the signal lines 19 and 25. Also, the DC 24V car call and hall call signals input via the signal lines 21 and 26 are converted into DC 5V call signals and sent to the main controller 13.

  In general, the main control device 13 can only calculate a DC5V control signal, whereas in the external environment of the main control device 13 such as the hoistway 5 and the tail cord, when signals are communicated with the DC5V control signal, motor inverter noise, etc. There is a risk of causing malfunction due to noise environment.

Further, the hall control board 22 on each floor is provided with a digital dot matrix LED display 3, a hall transmission control unit 30, and a hall call button 24.

  The main transmission control unit 28 in the main control panel 15 corresponds to the digital dot matrix LED display 3 of the car control panel 16 and the digital dot matrix LED display 3 of each hall control panel 22 output from the main control device 13. The parallel display signal is converted into a serial display signal and transmitted to the car transmission control unit 29 and the landing transmission control unit 30 via the serial signal lines 31 and 32, respectively.

  The car transmission control unit 29 converts the serial display signal input via the serial signal line 31 into a parallel display signal, and controls the display of the digital dot matrix LED display 3 with the parallel display signal. Further, as shown in FIG. 15, the car transmission control unit 29 converts the parallel car call signal input from the car call button 17 into a serial car call signal and converts the parallel car call signal to the main transmission control unit via the serial signal line 31. 28.

  Each hall transmission control unit 30 converts the serial display signal input via the serial signal line 32 into a parallel display signal, and controls the display of the digital dot matrix LED display 3 with the parallel display signal. Further, each hall transmission control unit 30 converts the parallel hall call signal input from the hall call button 24 into a serial hall call signal and transmits the serial hall call signal to the main transmission control unit 28 via the serial signal line 32.
