Note that R, S, and T represent three-phase AC power supplies, and + and-represent control power supplies. The time limit of the first timer 9 (the time from the start of timing to the count up) is a time obtained by adding a margin time to the time required for the step to move from the entrance to the exit of the passenger conveyor, for example, the floor height. In the case of an escalator of 3.5 to 4 meters, the time is set between 1 minute and 1 minute and 30 seconds, and the time of the second timer 10 (the time from the start of the time measurement until the count up) is set to the user The time required from the detection by the second detector 8 until the user moves and is detected by the first detector 7 is set to, for example, a time between 10 and 30 seconds. The time period is longer than the time period of the second timer 10. Then, the timing of the first timer 9 and the second timer 10 is set to zero (the counter is reset once every time a passenger is detected) while the passenger is being detected, so that the timer starts from the last passenger detection. Has become.
[0023]
Next, the operation of this embodiment will be described.
[0024]
In the following description, it is assumed that the operation is stopped when the operation is started, and the operation is controlled in conjunction with the detection signals of the first and second detectors 7 and 8.
[0025]
When the operation switch 13 is turned upward, the power is turned on (turned on), the detection signals of the first and second detectors 7 and 8 become valid, and the operation of the operation mode described below is started.
[0026]
When the customer appears and reaches around the entrance 1, the second detector 8 detects the person and outputs a customer detection signal. When the second detector 8 detects a person, the second timer 10 starts operating.
[0027]
Thereafter, when the passenger reaches the area surrounded by the handrail 2 of the entrance 1 and crosses the first detector 7, the first detector 7 detects the passenger and outputs a passenger detection signal. Based on this passenger detection signal, the first timer 9 starts operating when the first detector 7 detects a passenger.
[0028]
The first timer 9 and the second timer 10 operate independently, and the rotation speed of the drive motor 5 is determined by the operating states of these two timers. That is,
(1) Neither the second detector 8 nor the first detector 7 detects a user, the first timer 9 and the second timer 10 are both stopped, or the first detector 7 and the second detector 8 are Is detected, the drive motor 5 is stopped and the operation is stopped when the time limit of each timer has already expired.
[0029]
(2) The second detector 8 detects the customer and the second timer is executing time counting, and the first detector 7 does not detect the customer, the first timer 9 stops, or the first detection. When the device 7 detects a user, but the time limit of the first timer has already expired, the drive motor 5 is rotated at a low speed, and operation is performed at a low speed, for example, an arbitrary speed of 5 to 15 meters / minute.
[0030]
(3) When the first detector 7 detects a customer and the first timer 9 is executing timekeeping, the drive motor 5 is rotated at a preset normal rotation regardless of the operation of the second timer 10, Normal speed (high speed) For example, operation is performed at an arbitrary speed of 30 meters / minute or 30 to 40 meters / minute.
[0031]
For example, when the second detector 8 detects a passenger in the stop state, the second timer 10 starts counting time and low-speed operation. Thereafter, when the first detector 7 detects a user during low-speed operation, that is, before the time limit of the second timer 10 has elapsed, the first timer 9 starts counting time, and the number of rotations of the drive motor 5 is increased to increase the normal speed. Drive. On the other hand, when the time limit of the second timer 10 has elapsed without the second detector 8 and the first detector 7 detecting the user, the drive motor 5 stops rotating and stops operating.
[0032]
If the first timer 7 has expired without the first detector 7 and the second detector 8 detecting the passenger after the first detector 7 detects the passenger and starts normal operation, Since the second timer 10 has a shorter time limit than the first timer 9, it has expired and stopped, so the drive motor 5 stops rotating and stops operating.
[0033]
When the first detector 7 detects a customer and starts normal operation and then the second detector 8 detects another user, the normal operation is performed until the time limit of the first timer 9 elapses. To continue. When the time limit of the first timer 9 has elapsed and the time limit of the second timer 10 has not elapsed, the drive motor 5 decreases the rotation speed and performs low-speed operation.
[0034]
Further, when the second detector 8 on the exit side detects a person in a state where the rotation of the drive motor 5 is stopped, the buzzer 12 operates to notify the user of the reverse approach. When the first detector 7 detects a person, the buzzer 12 operates, and drives the step 2 and the handrail 4 in the direction from the entrance to the exit at a predetermined moving speed for a predetermined time.
[0035]
The rotation of the drive motor 5 is changed to a rotation speed according to the operating conditions of the first timer 9 and the second timer. For this reason, the constant speed variable control circuit 6B sends the frequency to the speed converter 6A at a predetermined acceleration (or deceleration) so that the frequency approaches a preset frequency from the frequency created earlier. By sending the changed command, the speed converter 6A generates a three-phase alternating current whose frequency is gradually changed. This is supplied to the drive motor 5 to change the rotation speed. When the frequency generated by the speed converter 6A reaches the frequency corresponding to the preset operation speed, the drive motor 5 is operated at the specified speed by the three-phase alternating current of the same frequency.
[0036]
When the operation switch 13 is moved downward, the power is turned off (turned off), the detection signals of the first and second detectors 7 and 8 become invalid, and the operation of the operation mode described above is terminated.
[0037]
According to the above embodiment, the following effects can be expected.
[0038]
When only the second detector 8 detects a person, since the detected person may not use the passenger conveyor, the vehicle stands by at a low speed for a fixed time, and the first detector 7 detects the person within the fixed time. In this case, the passenger can be regarded as a passenger who uses the passenger conveyor without fail, and the speed converter 6A can accelerate the vehicle to the rated speed by smooth acceleration to extend the operation time. On the other hand, if the first detector 7 does not detect a person during the standby operation at a low speed for a certain period of time, the person detected by the second detector 8 can be regarded as not a user of the passenger conveyor. Thus, it is possible to stop the passenger conveyor, reduce unnecessary operation time, improve operation efficiency, and reduce power consumption of the drive motor 5. If the second detector 8 on the exit side detects a person while the vehicle is stopped, both a person who has entered by mistake or a normal pedestrian can be considered. When the one detector 7 detects a person, it can be regarded as a person who has accidentally entered the vehicle. Therefore, by raising the buzzer 12 and alerting the user to the strength by driving for a certain period of time, it is expected that the user's safety and driving efficiency will improve. .
[0039]
Further, since the second detector 8 is installed on the floor plate near the lower part of the handrail curved portion, the complexity of wiring of the balustrade can be reduced. Further, maintenance of the second detector 8 is facilitated.
[0040]
In the above description, when the second detector 8 detects a person when the step 2 is stopped, an operation of starting the step 2 at a low speed is performed. If no person is detected, the operation of step 2 is continued at a low speed or a very low speed (a speed at which movement can be visually confirmed). If at least one of the detectors 7 and 8 detects a person, the step 2 can be driven at a predetermined normal speed (faster than the low speed). At this time, the set time of the first timer 9 operated by the detection of the first detector 7 and the set time of the second timer 10 operated by the detection of the second detector 8 can be different times.
[0041]
In the above description, the first timer 9 and the second timer 10 are provided outside the variable speed control circuit 6B, but they may be provided inside the variable speed control circuit 6B.
[0042]
In the above description, when the second detector 8 on the exit side detects a person, only the buzzer 12 operates, but the buzzer 12 is operated, and the step 2 and the handrail 4 are moved from the entrance 1 to the exit. , And the operation speed when the second detector 8 detects a person can be a high-speed operation.
[0043]
In the above description, the buzzer 12 is provided as a device for alerting passengers, the buzzer 12 is operated when a person enters from the exit side, and a warning is given to a person who has entered in a reverse direction. In addition, it is possible to provide a voice synthesizing device, a device for giving a visual warning by a lamp or a character display device, or a device for forcibly preventing entry by an automatic door.
[0044]
【The invention's effect】
As described in detail above, according to the present invention, since the second detector is installed on the floor plate near the lower part of the handrail, the wiring of the balustrade can be facilitated and the maintenance of the second detector can be facilitated. . In addition, we will accurately detect people who are likely to use it, and people who are certain to use it in the future, and if a person who is likely to use it is recognized as a person who will definitely use it, from the entrance to the exit If sufficient time is available, and if the prospective user is perceived as a person or mischief passing near the entrance of the passenger conveyor, shorten the driving time to improve driving efficiency and improve driving efficiency. It is possible to provide a passenger conveyor operating device that contributes to reducing the power consumption of the motor.
[0045]
In addition, it is possible to provide a passenger conveyor operating device that can provide two levels of alerting to a person who has accidentally entered the exit from the exit depending on the entry position, and contributes to ensuring safety and reducing unnecessary driving. .
