Definitions
- the present invention relates to an elevator in which a car moves up and down in a hoistway, and is particularly suitable for an elevator equipped with a safe position sensor that detects the position of the car (landing detection) and the door zone.

- Patent Document 1 simply detects the door zone with a single sensor and prevents malfunction due to external light. Therefore, it is difficult to increase the number of sensors as a sensor for detecting the door zone and re-flooring for correcting a minute level difference. For this purpose, the number of sensors has to be increased.
- An object of the present invention is to solve the above-mentioned problems of the prior art, and in particular, to improve safety and reliability by making it possible to detect a door zone even if the position detection sensor itself fails.
- Another object of the present invention is to simplify the system configuration even when the multi-functionality, safety and reliability are improved, and to increase the redundancy of the entire system including erroneous detection.
- another object is to eliminate a failure or a false detection due to a rope being caught on the sensor itself or the like during an earthquake.
- the present invention is to achieve at least one of the above objects.
- the present invention provides an elevator with a safety position sensor that detects a door zone indicating a region where a passenger can get on and off when the position of the car reaches a lift position where the car and landing door can be opened and closed.

- the car 100 is moved when the sheave 103 is driven by the electric motor 105.
- Electric power for driving is supplied to the electric motor 105 by the power converter 107.
- a pulse generator 106 such as an encoder is attached to the electric motor 105, and the system controller 108 counts the pulses generated by the rotation of the electric motor, whereby the speed of the driving electric motor 105 and the moving direction of the hoistway of the car 100 are counted. The equivalent position, distance moved, etc. are calculated.

- the position detection sensor can be a photoelectric, magnetic (use of magnet, high frequency magnetic field, etc.) or electrostatic capacitance non-contact detection sensor.
- the reflection type photoelectric detection sensor that detects light does not cause the ropes to be caught on the sensor itself or the detected plate 1 at the time of an earthquake, etc., and has high directivity and can detect the detected plate with high accuracy. This is desirable. However, since infrared light or the like is used, there is a risk of erroneous detection due to ambient light such as sunlight, dust, or water droplets.

Although 100 is in the door zone, it can be determined that it is displaced upward. At this time, if the car 100 moves slightly downward, on the other hand, the signal 3S is turned off and the logical operation is 10, so that it can be determined that the signal is shifted downward.

- the output OFF state (d) of only the position detection sensor 3 occurs when the car 100 moves by the minute step detection length M shown in FIG. Therefore, when the OFF state of the position detection sensor 3 is detected, the system controller 108 gives a command to move the car 100 by the minute step detection length M, and floor alignment control is performed again.

Further, even if one of the position detection sensors 3 and 4 fails and is turned OFF, the signal 5S is turned ON, and at least the door zone can be detected. Further, it can be determined by the logical operation unit 5 or the system controller 108 that one of the failure has occurred based on the logical AND output signals of the position detection sensors 3 and 4.

- the position detection sensors 2, 3 and 4 are not detecting anything, and are all in the OFF state.
- the signal 5S taking the OR output as the logical operation of 3S and 4S is also ON, and the detection of the door zone is duplicated and the redundancy is increased.
- the state (c) is entered, and the output of each signal is all ON. Also, from the state (c), if the passenger gets on and off at once and the elevator car moves slightly due to the expansion and contraction of the rope, and there is a small step between the car 100 and the floor 115, the process proceeds to (d).

It can be determined that there is a gap. On the other hand, if the car 100 moves slightly downward, it can be determined that the signal 3S is turned OFF and the ON signal 4S is shifted downward.
- the output OFF state (d) of only the position detection sensor 3 occurs when the car 100 moves by the minute step detection length M shown in FIG. Therefore, when the OFF state of the position detection sensor 3 is detected, the system controller 108 gives a command to move the car 100 by the minute step detection length M, and floor alignment control is performed again.
- the shape of the plate 1 to be detected is such that the output signal 5S of the logic unit 5 is the same as that of the output signal 2S of the position detection sensor 2 with respect to all positions of the hoistway. Since the interval between the position detection sensors 2 and 3 and 4 is determined, it is possible to make the door zone detection function and the re-flooring function compatible with each other, and the door zone can be detected even if any of the position detection sensors fails. Therefore, the redundancy of the entire system including erroneous detection can be increased. In addition, since the position detection sensors and their detected plate portions are arranged in two rows in the horizontal direction of the hoistway, it is possible to store compactly despite the increased redundancy, and in a limited and narrow installation space.
