An escalator monitoring system includes a data collection device disposed near parts of an escalator that need to be monitored for collecting data of the parts; a data transmittal device used to transmit data relevant to safe operation of the escalator; a local data processing device or cloud processors used to receive the data relevant to the safe operation of the escalator, to compare it against a threshold value stored therein and derived from the parts in normal operating conditions, and to respond to comparison result. The data collection device is a people traffic sensor for detecting the people traffic entering the escalator in a unit time, and an power sensor for detecting the power consumption in a unit time, a data transferring unit transfers the people traffic detected in a unit time and the power consumption detected in a unit time to the local data processing device or the cloud processors, the local data processing device or the cloud processors determines the running condition of the escalator according to the relation between the people traffic in a unit time and the power consumption in a unit time to determine whether or not an alarm signal needs to be sent.

The invention relates to an electronic safety device and a conveyor system comprising the same. The electronic safety device has a safety input for receiving a safety signal, the electronic safety device being configured to terminate its operation responsive to absence of the safety signal in the safety input. The electronic safety device comprises an operation-preventing circuit configured to detect an operational anomaly in the safety input, the operation-preventing circuit comprising a switch adapted to short the safety input when the operational anomaly is present in the safety input.

Provided are an abnormality detection system, an abnormality detection device, an abnormality detection method, a computer program, and a chain that enable detecting of an abnormality not only in a chain but also in equipment using the chain while distinguishing the location at which the abnormality occurs. The abnormality detecting system comprises a sensor unit comprising a sensor, to be fixed to a chain that is to be attached to equipment, and transmitting an output from the sensor, a detection section which detects an abnormality of the chain or the equipment based on the output, and a determining section which determines a location of the abnormality in the equipment, based on a position of a part fixed with the sensor unit in the equipment, the position changes in each time point with moving of the chain.

There is disclosed a display device making it possible to call effective attention in a use situation where unbalanced passenger load occurs between left and right lanes of a passenger conveyor. This display device includes a first display unit (7A) positioned on the left and a second display unit (7B) positioned on the right toward the passenger conveyor at a boarding (1), a control device (20) to control the first display unit (7A) and the second display unit (7B), and passenger detection means (8A, 8B) to detect passengers stepping on the passenger conveyor. The first display unit (7A) and the second display unit (7B) display images representing information to passengers. The passengers pass between the first display unit (7A) and the second display unit (7B) and step on the passenger conveyor. The control device (20) estimates a state of congestion and a state of passengers gathering on only one lane in the passenger conveyor, based on detection signals from the passenger detection means (8A, 8B), and sets an image to be displayed by the first display unit (7A) and an image to be displayed by the second display device (7B) independently, depending on the state of congestion and the state of passengers gathering on only one lane.
