Embodiment Construction

[0032]

[0033] In this specification, the housing of the elevator on which passengers ride is called a "car". figure 1 It is a block diagram showing the configuration of an elevator system including the rope-shaped object detection device 2 of the present embodiment.

[0034] figure 1 The elevator control device 1 has a control unit 15, and the control unit 15 is constituted (implemented) by software (program) executable by a microcomputer. In addition, the elevator control device 1 is electrically connected to the rope-shaped object detection device 2, and can transmit and receive signals such as the detection result S2.

[0035] The control unit 15 of the elevator control device 1 performs door opening and closing control based on the detection result S2 from the rope-shaped object detection device 2 and execution control of a notification process using the notification processing unit 9 .

[0036] figure 1 The shown rope-shaped object detection device 2 has a first de...

Abstract

The invention provides a rope shaped object detecting apparatus an elevator system. The invention does not complicate a structure but can detect a rope shaped object with high precision. The first detecting unit of the rope shaped object detecting apparatus detects a rope shaped object based on the cutoff condition and time change of a plurality of light transmitting paths formed at the door sensor part. More technically, the first detecting unit detects blocks according to step ST12 and actuates ST14 afterwards. Under the condition when number L light path is blocked, the ST15 detecting time adds one. When in ST16, the detecting time NK is equal to or above the valve value M, the following step ST17 decides that a rope shaped object exists in an elevator.

Description

technical field [0001] The present invention relates to a rope-shaped object detection device which detects the presence of a rope-shaped object in a passenger space serving as an elevator entrance and exit, and an elevator system for controlling an elevator based on the detection result of the rope-shaped object detection device. Background technique [0002] At present, in order to prevent passengers from being caught by the elevator doors, most elevator systems are equipped with door sensors (photoelectric sensors) formed by vertically arranging a plurality of light-receiving elements and light-emitting elements on the left and right ends of the door. Such an elevator system is controlled by using the door sensor to form a plurality of horizontal light beams (light transmission paths) that are transmitted and received between a plurality of light-receiving terminals and light-emitting terminals across the boarding space as the elevator entrance and exit when the door is op...
