Infrared anti-collision prompting apparatus of tower crane

Abstract

The invention provides an infrared anti-collision prompting apparatus of a tower crane. The apparatus comprises a pyroelectric infrared sensor, a signal processing system connected with the pyroelectric infrared sensor and an alarm device connected with the signal processing system, and the signal processing system comprises a signal emitter, an amplification circuit and a signal receiver. The apparatus has the following advantages: 1, the sensitivity is high by using infrared ray to induce a mobile object; and 2, the mobile object can be induced in tens of meters range in high altitude, and a signal is rapidly fed back to an operator within 1s.

Description

technical field [0001] The invention relates to an infrared anti-collision reminder device for a tower crane, which belongs to the technical field of high-altitude equipment. Background technique [0002] With the rapid development of economic construction, the number of large tower cranes widely used in various construction projects is increasing, and the layout density is increasing. In recent years, collisions between tower cranes, collisions between tower cranes and surrounding buildings, and other safety accidents have occurred frequently. [0003] At present, there is a lack of anti-collision reminder devices for tower cranes, and there are potential safety hazards in the working process, which cannot be automatically alarmed. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an infrared anti-collision reminder device for tower cranes. [0005] The tower crane infrared anti-collision...
