System for monitoring safety of tower crane

Abstract

The invention relates to a safety technology for remotely monitoring a tower crane, in particular to a system for monitoring the safety of a tower crane. In the system, the output ends of an inclination angle sensor, an angle sensor, a height sensor, an amplitude sensor, a wind speed sensor and a weight sensor are electrically connected with the input end of a signal conditioning module respectively; the output end of the signal conditioning module is electrically connected with the input end of a micro processor; a storage module, a key input module, a voice alarm module and a control output module are electrically connected with the micro processor module; the micro processor module is further electrically connected with an RS232 module; and a global positioning system (GPS) module, a liquid crystal display, a general packet radio service (GPRS) module and a ZIGBEE module are electrically connected with the RS232 module respectively. In order to guarantee the signal processing instantaneity, the micro processor module adopts two micro processors for coordination and distribution of responsibilities; and the two micro processors exchange data with each other by using a system management bus (SMBus), so the high-instantaneity and all-round monitoring of the safety of the tower crane during running can be realized, and safety accidents can be avoided.

Description

technical field [0001] The invention relates to a technology for remotely monitoring the safety of tower cranes, in particular to a safety monitoring system for tower cranes. Background technique [0002] At present, the existing tower crane safety monitoring devices generally can only realize the collection of signals such as load, wind speed, angle, amplitude, height, etc., and do not have the function of tower inclination detection. Although there are remote monitoring functions or area collision avoidance devices on the market A tower crane safety monitoring device with multiple functions, but the function is single, so it cannot realize complete monitoring and safety protection for the tower crane. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages, provide a tower crane safety monitoring system, realize all-round safety monitoring, and avoid safety accidents. [0004] The present invention realizes multi-cha...
