Self-networking tower crane monitoring system based on ZigBee technique

Abstract

The invention discloses a self-networking tower crane monitoring system based on a ZigBee technique. The self-networking tower crane monitoring system comprises a tower crane monitoring instrument and a monitoring platform which are arranged in corresponding tower crane cabs, wherein the tower crane monitoring instrument collects signals of a tower crane and transmits the signals to the monitoring platform. The self-networking tower crane monitoring system is characterized in that the tower crane monitoring instrument comprises a ZigBee module, a main control unit, an information collection unit and an information collection unit, wherein the information collection unit collects relevant signals and transmits the signals processed by an information processing unit to the main control unit, the main control unit processes the signals and transmits the processed signals to the ZigBee module, and the ZigBee module receives data from the main control unit, selects a routing path after packing the data and transmits the packaged data according to a standard protocol. According to the self-networking tower crane monitoring system based on the ZigBee technique, the communication distance can be up to above 1000 meters, the penetrating strength is strong, and the communication is normally carried out when being obstructed by buildings.

Description

technical field [0001] The invention relates to the field of tower crane safety monitoring, in particular to a tower crane monitoring system based on an ad hoc network of ZigBee technology, which provides tower crane operators with a system for real-time monitoring of the operating states of multiple tower cranes working simultaneously. Background technique [0002] In recent years, the research on the safety monitoring system of tower cranes has continued to deepen, various research reports and products have emerged, and some products have also applied for related national patents. Most of the products use PLC to realize the electrical control of the tower crane, and use the text display to display the main parameters in the operation process of the tower crane online in numerical form. When the measured value exceeds the set value, it will automatically alarm and cut off the corresponding control circuit. In addition, it is proposed that the upper computer can communicate ...

AI Technical Summary

Problems solved by technology

[0006]2. Communication characteristics, the penetration ability of GPRS signal is insufficient, and the anti-interference is weak. It is difficult to guarantee the signal in the complex environment of the construction site with many high-rise buildings in big cities and serious electrical interference. The intensity of the communication will lead to a temporary interruption of communication, and it will take time to reconnect.

If an accident occurs at this time, the consequences will be disastrous

[0007]3. Cost problem, the price of GPRS module is basically around 1500, which is very expensive
