Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] The basic idea of the wireless information interaction method and system between tower cranes with adjustable communication rate according to the present invention is as follows: firstly, design a wireless communication protocol that joins the network according to the tower crane overlapping situation, and establish wireless information interaction between overlapping tower cranes Network; then, the tower crane with the highest possibility of collision enjoys the highest communication rate, and the communication rate between tower cranes can be adjusted on demand. Finally, a set of wireless information interaction system between tower cranes is designed to adjust the communication rate on demand.
[0025] The wireless information interaction method between tower cranes that adjusts the communication rate on demand according t...

The invention discloses a wireless information exchange method and system between tower cranes for adjusting the communication rate on demand. The tower crane node is added to the network; the real-time rotation angle of the tower crane is compared with the critical angle of the free zone, buffer zone, and overlap zone to obtain the current area of the tower arm, and the communication priority is automatically adjusted according to the area attributes; according to the communication priority Automatically adjust the data sending online node list, so that the node with the highest priority enjoys the fastest data sending frequency, and timely send the dynamic data of the tower crane to the overlapping tower crane. The system includes an information detection device, a wireless radio frequency module, an information preprocessing device, and an embedded tablet computer, and the systems communicate according to a wireless information interaction protocol. The invention can adjust the data transmission frequency as needed, so that the tower crane node most likely to collide has the fastest data transmission speed, and provides parameters for the anti-collision decision in time.
Description
technical field [0001] The invention relates to a tower crane information interaction method and system, in particular to a wireless information interaction method between tower cranes whose communication rate is adjusted on demand and an adopted system, belonging to the field of wireless communication. Background technique [0002] In order to ensure the safe operation of the tower crane, it is required to install an electronic anti-collision system on the tower crane. The tower crane electronic anti-collision system needs to clarify the real-time position relationship between tower cranes through the communication between tower cranes. The wired method needs to lay communication cables. Due to the complex construction environment on site, it is inconvenient and costly to lay communication cables, and the laid cables are also easily damaged. The tower crane group working on a construction site has a limited distribution area. It is not only feasible to communicate the rea...
