摘要:
The present invention provides a temperature monitoring system for a passenger transport apparatus, a passenger transport apparatus having the same and a temperature monitoring method for a passenger transport apparatus, wherein the temperature monitoring system comprises: a temperature detection apparatus (28, 29); and a control apparatus (27) associated with the temperature detection apparatus (28, 29). When the temperature of at least one of a plurality of components is lower than a corresponding working temperature range, the control apparatus sends out a notification message and/or enables a heating apparatus to heat the component; when the temperature of at least one of the plurality of components reaches an early warning temperature range, the control apparatus sends out a notification message and/or enables a heat dissipation apparatus to dissipate heat for the component; and when the temperature of at least one of the plurality of components continues to rise and exceeds the corresponding working temperature range, the control apparatus sends out a notification message and/or enables the passenger transport apparatus to brake. The present invention is able to monitor a component running condition and predict a component service life, thereby taking a corresponding measure in advance.

A main drive shaft brake for a passenger conveyor includes a braking element, an actuator, and a counter-actuator. The actuator is de-energized to release the braking element and halt operation of the passenger conveyor during an abnormal or emergency condition. An energized counter-actuator permits release of the braking element but, when de-energized, inhibits release of the braking element by the actuator to prevent unintentional release of the braking element caused by, for example, an accidental loss of power to the actuator.

A conveyor system has a plurality of sensors coupled to a computer system, the computer system being programmed to check a number of safety functions greater than the number of sensors. A method of controlling the safety function of the conveyor comprises providing signals from a plurality of sensors disposed in relation to the conveyor to a computer system; operating the conveyor in a learn mode; during operation in the learn mode determining in the computer system the relationship between the sensor output signals and pre-stored logic in the computer system which describes the physical geometry of the possible conveyor types and permissible operating characteristics thereof and determining the relationship between the sensor output signals to establish the safety integrity of the sensors, and storing sensor signal patterns as a reference pattern; and subsequently operating the conveyor in a run mode in which safety functions are monitored; and during the run mode comparing in the computer system the pattern of sensor signals with the reference pattern and with the pre-stored logic so as to establish the safety integrity of the sensors, of the computer system and of the operation of the conveyor.

The present invention relates to the field of passenger conveyor technologies, and provides an engaging state detection system of a passenger conveyor and a detection method thereof. In the engaging state detection system and detection method, a depth sensing sensor (310 1 , 310 n ) is used to sense at least an engaging portion between a step (904) and a comb plate (903) of the passenger conveyor (900) to obtain depth maps, and the depth maps are analyzed by a processing apparatus (100) to detect whether an engaging state between the step (904) and the comb plate (903) is a normal state. The detection of the engaging state includes detection on whether comb teeth of the comb plate are broken, whether engaging teeth of the step are broken, and/or whether a foreign matter exists on an engaging line.

A people conveyor (2) comprises two landing areas (4, 6) located at two opposing ends of the people conveyor (2); a movable conveying element (8) extending between the two landing areas (4, 6) and configured for conveying passengers between the two landing areas (4, 6); a handrail (12) extending parallel to the conveying element between the two landing areas and configured for moving with the conveying element (8); a handrail exit/entry portion (19) located at one of the landing areas (4, 6) and configured for receiving a return portion of the handrail (12); and a safety switch assembly (31) provided at the handrail exit/entry portion (19) and configured for stopping the handrail (12) when activated. The safety switch assembly (31) comprises at least one sensor surface (27, 29) providing a touch sensor for detecting any part of a human body, in particular a finger, approaching and/or touching at least one of the at least one sensor surfaces (27, 29).

The present invention provides a moving handrail monitoring system for a passenger conveying device, a passenger conveying device, and a monitoring method thereof. The moving handrail monitoring system includes: an imaging sensor and/or a depth sensing sensor (210) configured to sense at least part of a moving handrail (110) of the passenger conveying device (100) to acquire a data frame; a processing device (200) configured to analyze and process the data frame to monitor whether a tension degree of the moving handrail is in a normal state, wherein the processing device (200) is configured to include: a target object recognition module configured to recognize, based on a sensed movement and/or position and/or color and/or shape, a moving handrail portion that serves as a target object from the data frame; an object feature extraction module configured to extract a tension degree feature of the moving handrail portion; and a judgment module configured to compare the extracted tension degree feature with a system preset interval, and judge whether a current tension degree of the moving handrail is normal.
