Embodiment

[0037]The tower group consists of 6 tower cranes. The sub-agent of each tower crane uses the embedded Cortex-M3 platform to sample 5 status information of the tower crane (including rotation angle, amplitude, height, hoisting weight and wind speed). The data sampling frequency of the tower crane is 100 milliseconds, and the sub-Agent executes an anti-collision algorithm at a period of 200 milliseconds. Considering that the fastest speed of the tower crane is 270 degrees / minute (or 4 degrees / second), in order to ensure the real-time performance of the anti-collision algorithm, the communication frequency between sub-Agents is set to 250 milliseconds / time (that is, the information between all tower cranes The exchange frequency is 250 ms / time),

[0038] For the anti-collision algorithm between tower cranes, the wireless communication mode between tower cranes is set to: asynchronous transmission with a communication baud rate of 9600b / s, and each frame of data between tower cran...

Abstract

The invention discloses an anti-collision system control method based on a distribution multi-agent tower group. The method includes that step 1, a sub Agent is arranged on each tower crane of the tower group, and the sub Agents are subjected to networking; step 2, the distribution multi-agent tower group adopts a parallel working mode, the sub Agents achieve functions of a single crane, and information collection, function decision and output control of each tower crane are achieved through an information collecting module, a function decision module and an output control module respectively; step 3, time-sharing scheduling control among the sub Agents is achieved through communication protocols preset in communication modules of the sub Agents. By means of the anti-collision system control method, communication among the tower cranes of the tower group is smooth, anti-collision calculation real-time performance is good, the control process is reliable, and operation of each tower crane is safe and smooth.

Description

technical field [0001] The invention belongs to the technical field of tower group safety control, and is used for anti-collision control when multi-tower cranes work together, in particular to a control method based on a distributed multi-agent tower group anti-collision system. Background technique [0002] Tower cranes (also known as tower cranes) are the main means of transportation for building houses and bridges. The tower crane has a high center of gravity, a large lifting load, and a fast running speed. There are many risk factors in the work, especially in modern large-scale construction sites. In the case of multi-tower cranes working together, it is easier to Serious accidents such as collisions occur. [0003] The agent (Agent) first appeared in the field of artificial intelligence, and is an individual with the ability of perception, decision-making, interaction and control. Distributed multi-agent system (Multi-Agent System referred to as MAS) is a system com...
