摘要： A safety monitoring device monitoring safety-related states in a passenger conveyor system has first and second double contact relays each controlled by a control voltage to switch first and second normally open contacts and a feedback contact synchronously between an open and closed relay states. First and second controllers each determine properties of the system correlated with safety-related states and in dependence generate the control voltages. The controllers and two double contact relays form first and second safety monitoring switch arrangements for monitoring first and second safety-related states and correspondingly switch first and second switching states within a safety monitoring chain of the system. The first arrangement includes the first contact of the first connected in series with the first contact of the second relay. The second arrangement includes the second contact of the first relay connected in parallel with the second contact of the second relay.

摘要： There is provided an auxiliary brake of a passenger conveyor that can be easily released. The auxiliary brake of the passenger conveyor includes: a braking wheel comprising a groove on one side face, the groove being depressed in a direction of a rotation axis and having a face parallel to the rotation axis on one end, and the braking wheel being provided so as to rotate synchronously with a main axis of a sprocket of the passenger conveyor; and a pole having a shape of a rod and provided being movable in the direction of the rotation axis of the braking wheel, the pole being displaced between a first position of coming into contact with any face of the groove and a second position of not coming into contact with any face of the groove.

摘要： There is provided a method of renewing a passenger conveyor that is capable of preventing the passenger conveyor from being unavailable for a long time period when the passenger conveyor is renewed in a stepped manner. The method of renewing a passenger conveyor includes a safety device update process of updating an existing safety device to a new safety device in the passenger conveyor, and a drive machine and control panel update process of, after the safety device update process, updating an existing drive machine of the passenger conveyor to a new drive machine and updating an existing control panel of the passenger conveyor to a new control panel.

摘要： A passenger moving installation includes a plurality of tread elements forming an endless conveyor belt, wherein the tread elements are at least partially covered by at least one element that limits a transportation height of a user set of the installation. A safety system is configured to detect a risk of collision between the user set and the covering element. A method of determining a risk of collision between a user set and at least one covering element in a passenger moving installation at least partially covered by the covering element, includes determining the height of the user set in a monitoring area via a safety system, comparing the height of the user set to the height of a safety threshold, and triggering an event in the safety system if the user height exceeds the safety threshold.

摘要： A monitoring system for a passenger conveyor including: at least one acceleration sensor provided on a movable component of the passenger conveyor, wherein the moveable component moves in a closed loop path (P) when the passenger conveyor is in use; a fault detection sensor associated with the or each acceleration sensor and configured to provide data indicative of a fault in the moveable. The monitoring system includes a controller configured to: receive data from the or each acceleration sensor; monitor a gravity vector (V) of the or each acceleration sensor; determine a direction of travel of the or each acceleration sensor; determine a current location of the or each acceleration sensor based on the monitored gravity vector (V) and the determined direction of travel; detect a fault from the data received from the or each fault detection sensor; identify a location of the detected fault.
