Benefits of technology

This patented technology provides an improved way for safety during maintenance work inside buildings where there are many objects such as tools used while working within it. By having lights along the top surface of each floor instead of just below them, workers will see everything they shouldn't get hurt if someone tries their best guess wrong ways. Additionally, this design helps protect people who enter through doors without being detected because these signals indicate something like approaching too much weight. Overall, this innovative solution improves efficiency and reduces risk factors associated with building operations.

Problems solved by technology

This patents describes how we are constantly exposed to harm caused when an elevated object enters our hoistway through accidental mistakes during operation due to external factors like dirt particles falling onto the floor surface around them. These issues could lead to accidents with passengers inside the building being lifted off at high speeds without proper monitoring measures.

Abstract

The invention provides a lift shaft monitoring system and a monitoring method thereof. The lift shaft monitoring system comprises a lift shaft with a containing space, a lift car which does hoisting movement along the containing space of the lift shaft, a foreign matter detection system and a driving device for driving the lift car to move, wherein the foreign matter detection system comprises a light emitter, a light receiver and a controller; the light emitter covers a whole bottom wall of the lift car and emits longitudinal light for irradiating the light receiver; the light receiver is arranged at the bottom of the lift shaft and corresponds to the light emitter; the controller is connected with the light receiver and the driving device respectively. According to the lift shaft monitoring system and the monitoring method thereof, the foreign matter detection system is additionally arranged; when foreign matters appear in the lift shaft, the operation of the lift car can be stopped in time, so that on one hand, the lift car is protected from damages caused by the foreign matters; on the other hand, people and animals, who inadvertently stray into the lift shaft, are protected.
