Escalator safety detection device and detection method

Abstract

The invention provides an escalator safety detection device which comprises a first eddy current transducer and a second eddy current transducer, wherein the first eddy current transducer and the second eddy current transducer are arranged at two sides of an escalator footstep, the first eddy current transducer and the second eddy current transducer are connected with a safety detection processor, and the first eddy current transducer and the second eddy current transducer are arranged in a staggered mode. An escalator safety detection method includes a first step of collecting escalator footstep running information through the first eddy current transducer and the second eddy current transducer, and transmitting the escalator footstep running information to the safety detection processor, wherein the first eddy current transducer and the second eddy current transducer are arranged at two sides of the escalator footstep; a second step of enabling the safety detection processor to process the escalator footstep running information, and making safety judgment according to a process result. According to the escalator safety detection device and the escalator safety detection method, the problems that stairs of the escalator are staggered, lost and sunk and the escalator is overspeed are judged through information detected by the two eddy current transducers, the structure is simple, required installation space is small, and detection precision is high.

Description

[0001] 【Technical Field】 [0002] The invention relates to the elevator field, in particular to a safety detection device and a detection method for escalators. [0003] 【Background technique】 [0004] Escalators are common in shopping malls, office buildings, large buildings and other places to provide convenience for people’s lives. At the same time, the safety of escalators is also worth paying attention to. Escalators need to be overhauled regularly, and some testing equipment is required to reflect their operating status at any time during operation. Due to the structure of escalators It is complicated, and there are gaps in some locations. It is easy for foreign objects to fall into serious safety threats. Sometimes, mechanical failures may cause problems such as misalignment of escalator steps, missing steps, step sinking, and escalator overspeed. To detect these problems, you need to have corresponding detection equipment. Traditionally, these detection devices are installe...

Problems solved by technology

[0004] Escalators are common in shopping malls, office buildings, large buildings and other places, which provide convenience for people's lives. At the same time, the safety of escalators is also worthy of attention. Escalators need regular maintenance, and some testing equipment is also required to reflect their operating status at any time during operation. Due to the structure of escalators Complex, and there are gaps in some positions, it is easy for foreign objects to fall into a serious threat to safety, and sometimes due to mechanical failures, escalator step misalignment, step missing, step sinking, escalator overspeed and other problems, to detect these problems need to have corresponding detection equipment, Traditionally, these detection devices are installed at different positions of the escalator, and a corresponding number of detection elements need to be installed, which requires more components and devices, a more complex structure, more installation space, and insufficient accuracy. The information can not immediately reflect the problem
