System and method for monitoring interlocking multiple escalators

Abstract

The invention provides a system and method for monitoring interlocking multiple escalators. According to the system, an output end of a control module is connected with a first interlocking relay anda second interlocking relay; a first input end of the control module is respectively connected with a first end of a first normally closed contact and a first end of a second normally closed contact;a second end of the first normally closed contact of one escalator is connected with a first end of the first normally closed contact of an adjacent escalator along the first direction; a second end of the first normally closed contact of the last escalator along the first direction is connected with a signal source through a first normally open contact; the second end of the second normally closed contact of one escalator is connected with the first end of the second normally closed contact of the adjacent escalator along the second direction; and the second end of the second normally closedcontact of the last escalator along the second direction is connected with the signal source through a second normally open contact. By means of the system and the method, when the escalator carryingpassengers into an intermediate connecting platform fails and stops, the escalator taking the passengers away from the intermediate connecting platform continues to operate to evacuate the passengers.

Description

technical field [0001] The invention belongs to the technical field of escalators, and in particular relates to a monitoring and interlocking system and method for multiple escalators. Background technique [0002] Escalators are typical equipment for transporting passengers in public places. Because their efficiency in transporting passengers per unit time is much higher than that of vertical elevators, escalators have been widely used in shopping malls, airports, high-speed rail stations, subways, hotels and other places. use. On some floors with relatively high building distances and relatively long spans, such as subway stations, high-speed rail stations, large shopping mall complexes, etc., it may be necessary to install two or more escalators arranged consecutively. [0003] Under the existing technology, the safety circuits of two consecutively arranged escalators are usually connected in series. Through the emergency stop device installed at the height of the handra...

AI Technical Summary

Problems solved by technology

[0005] The above prior art has the following defects: after the safety circuit of any escalator is disconnected, multiple escalators arranged in succession stop at the same time, and passengers cannot be guided as quickly as possible, especially passengers with a lot of luggage, who walk on the escalator at a slower speed. This will cause traffic congestion, and there are no other exits on the connecting platform between the two escalators, which may cause safety accidents, especially for high-speed rail stations and subway stations where there are a large number of passengers and carry a lot of luggage. , but also the key safety hazards
