[0016]
In the push button failure detection device for an elevator configured as described above, response lamp failure detection of the push button 1 is performed as described below. That is, when the push button 1 of FIG. 1 is pressed, the call detection relay 2 is energized by the circuit of + -1-2-2-3-, and the normally open contact 2a and the normally open contact 2b are closed. When the normally open contact 2a is closed, the ascending operation relay 4 is energized by the circuit + -2a-4-5--, and the normally open contact 4a and the normally open contact 4b are closed.
[0017]
As the normally open contact 4a is closed, the ascending operation relay 4 is self-held by the circuit + -4a-4-5--. Further, since the normally open contact 2b is closed, the call relay 6 is energized by the circuit of + -2b-6-4b-7-- by closing the normally open contact 4b, so that the normally open contact 6a is normally opened. The contact 6b, the normally open contact 6c, and the normally open contact 6d are closed. The call relay 6 is self-held by the circuit of + -6a-6-4b-7-- by closing the normally open contact 6a.
[0018]
Further, the response lamp 8 is energized and lit by the circuit of + -6b-8-- by closing the normally open contact 6b. When the normally open contact 6c is closed, the time relay 9 is energized by the circuit + -6c-9-- and the normally open contact 9a is closed. Since the normally open contact 6d is closed, the response lamp failure detection relay 10 is energized by the circuit of + -6d-9a-10-- by closing the normally open contact 9a, and the normally open contact 10a is closed. To do.
[0019]
When the normally open contact 10a is closed, the response lamp failure detection apparatus 11 is energized by the circuit + -10a-11--. In the electric circuit of FIG. 1 described above, the response lamp 8 is energized via the call detection relay 2, the ascending operation relay 4, and the call relay 6 when the push button 1 is pressed. However, when the response lamp 8 is out of light bulb or the like and is not lit, the push button 1 is continuously and repeatedly pressed by the passenger of the elevator.
[0020]
At this time, when the number of times the push button 1 is repeatedly pressed exceeds a predetermined number of times in a short time, the response lamp failure detection device 11 operates to detect a failure of the response light 8 of the push button 1. The failure detection center of the elevator reports the failure detection of the response light 8 of the response light failure detection device 11. In this way, the non-lighting of the response lamp 8 of the push button 1 can be known easily and early. Therefore, it is possible to quickly respond to the non-lighting of the response lamp 8, and the operation of the elevator can be easily returned to the normal state with a small number of steps.
[0021]
In the elevator push button failure detection apparatus configured as described above, the operation failure detection operation of the push button 1 by the push button malfunction detection device 12 will be described with reference to the flowchart shown in FIG. That is, in step 101, the recording of the number of times the push button malfunction detection device 12 is pressed is reset to 0 o'clock in the day, and the process proceeds to step 102. If the elevator is not suspended, the process proceeds to step 103.
[0022]
In step 103, if 12 o'clock of the day has not elapsed, the push button malfunction detection is terminated, and if 12 o'clock of the day has elapsed, the program proceeds to step 104 to sequentially verify the pushing operation of all the push buttons 1. After the operation of the apparatus according to FIG. Then, in step 105, the recording of the number of presses of the push button malfunction detecting device 12 for the specific push button 1 is checked, and the process proceeds to step 106.
[0023]
If the average value of the number of times of pressing of the specific push button 1 in FIG. 4 corresponding to the specific push button 1 tested in step 106 is larger than 20, the process proceeds to step 107, and if the average value of the number of times of pressing is less than 20, Proceed to step 108.
[0024]
If the recorded number of times of pressing per day is not 0 in step 107, the process returns to step 104 to enter the pressing operation verification of the next push button 1. If the number of times of pressing recorded per day is 0, the process proceeds to step 109. . If the recorded number of presses per day is not 0 in step 108, the process returns to step 104 to enter the press operation verification of the next push button 1. If the recorded number of presses per day is 0, the process proceeds to step 110. .
[0025]
If the number of presses recorded on the same day of the previous week is not 0 in step 110, the process returns to step 104 to enter the press operation test for the next push button 1, and if the number of presses recorded on the same day of the previous week is 0. Proceed to step 109. In step 109, the push button malfunction detection device 12 detects the malfunction of the push button 1, and the process returns to step 104 to start the next push button 1 press operation test.
[0026]
In step 109, if the operation failure pushbutton 1 detected today is notified, the process returns to step 104 and the next pushbutton 1 press operation test is entered. Further, if not notified of the malfunctioning pushbutton 1 detected today at step 111, the process proceeds to step 112, and the detected malfunctioning pushbutton 1 information is reported to the failure management center of the elevator.
[0027]
As described above, the number of detected pressings for today on the specific pushbutton 1 is extremely small compared to the actual number of presses on the same day of the previous week of the specific pushbutton 1 stored in the pushbutton malfunction detecting device 12. Occasionally, the push button malfunction detection device 12 operates to detect malfunction of the specific push button 1. Thereby, it is possible to know the malfunction of the push button 1 easily and early. Therefore, the malfunction of the push button 1 can be promptly dealt with, and the operation of the elevator can be returned to the normal state with a small number of operations.
[0028]
【The invention's effect】
As described above, the present invention provides the number of presses of a specific pushbutton pressed against each of a plurality of pushbuttons, a timing device, and a pushbutton that are provided on an elevator operating device and operate when pressed and the response lamp is lit. A response lamp failure detection device provided with a recording device for recording the number of presses to be recorded and activated when the number of presses of a specific push button exceeds a predetermined number of times in a predetermined short time in a timed device and detects a response lamp failure of the specific push button And a press count recording device for recording the number of presses of the specific push button pressed against each of the time limit device and the push button, so that the press count of the specific push button is set to a predetermined number of times over a predetermined long time in the time limit device. In contrast, there is provided a push button malfunction detection device that operates when it is insufficient and detects malfunction of a specific push button.
[0029]
As a result, when the response light of the push button is out of light bulb or the like and is not lit, the push button is continuously and repeatedly pressed by the passenger of the elevator. For this reason, when the number of times the push button is repeatedly pressed when the response light is not lit exceeds the predetermined number of times in a short time, the response light failure detection device operates to detect a failure of the response light of the push button. In addition, when the number of times the specific push button is pressed for a predetermined long time stored in the push button malfunction detecting device is too short of the predetermined number of times for a long time, the push button malfunction detecting device operates and the specific push button malfunctions. Is detected. As a result, it is possible to easily and quickly know the failure of the response light of the push button and the malfunction of the push button. Therefore, it is possible to quickly cope with a push button failure, and to restore the operation of the elevator to a normal state with a small number of operations, thereby facilitating a recovery operation in the event of a push button failure.
