Embodiment

[0073] There are 2 tower cranes at a certain construction site, and each tower crane is equipped with an embedded tower crane monitoring AP, and an intelligent hoisting system is used to realize unmanned hoisting operations. The on-site wireless LORA LAN adopts the 1278A serial port LORA module produced by Shenzhen Lingchengxin Electronics Co., Ltd. (to achieve spread spectrum). The handheld tower crane wireless remote control AP and the embedded tower crane monitoring AP use the Cortex-M3 platform as the core and are independently designed; 433 wireless The communication is developed by LC4463 module; the software of the control system is independently developed.

[0074] The communication format between the embedded tower crane monitoring AP and the centralized scheduling AP is:

[0075] STX (start character) + terminal address (two digits) + command code (two digits) + data (n data) + LRC (validity code) + end character

[0076] Among them, the terminal address is to encod...

Abstract

The invention discloses a tower group smart accurate hoisting control method based on the Internet of Things. The method comprises the steps that (1) an ith tower crane wireless remote control Api applies a hoisting request for a centralized dispatcher AP; (2) the centralized dispatcher AP performs tower crane dispatching according to the hoisting application; (3) the tower crane wireless remote control Api starts the hoisting task; (4) an embedded tower crane monitor unit APk performs path planning and starts a smart cruise; (5) the embedded tower crane monitor unit APk starts a remote control mode and performs accurate positioning, and loading is conducted; (6) the embedded tower crane monitor unit APk starts the smart cruise state again; (7) after an executive tower crane k arrives at the target position, the tower crane wireless remote control Api remotely controls the executive tower crane k for accurate positioning again, and unloading is completed; and (8) the tower crane wireless remote control Api sends a hoisting ending command to the centralized dispatcher AP, the centralized dispatcher AP enables the executive tower crane k to be in an idle state, and so far, the wholehoisting process is completed. The method achieves smart control over hoisting of a tower group.

Description

technical field [0001] The invention belongs to the technical field of group tower hoisting monitoring, and relates to an intelligent and precise hoisting control method for group towers based on the Internet of Things. Background technique [0002] Tower cranes (referred to as tower cranes) are the main hoisting tools for building houses and bridges. High-rise buildings require higher and higher construction tower cranes. Tower crane drivers cannot see the loading and unloading conditions on the ground. The operation of tower crane drivers can only obey the ground command At this time, if the operation is too cautious, it will affect the work efficiency, and if it is too extensive, it may cause an accident. In this process, the tower crane driver needs to be highly concentrated, labor-intensive, and prone to fatigue, which is a major hidden danger of tower crane accidents; although the commander is sending out command signals as needed, he cannot be sure whether the tower c...
