Remote control method for tower crane

Abstract

The invention provides a remote control method and system for a tower crane. The remote control method is characterized in that a tower crane controller is arranged and used for acquiring whole machine working data of the tower crane and communicating with a wireless local area network; a wireless data acquisition device is arranged and comprises a wireless local area network module, a video module, a storage module and a display module; the wireless local area network module is used for communicating with the wireless local area network and sending out a command according to the acquired data; the video module is used for acquiring videos, and the acquired videos are processed through the wireless data acquisition device; the storage module is used for storing the data; and the display module is used for displaying a curve drawn according to the received wireless transmission data and video images. The remote control method and system for the tower crane have the beneficial effects that the data can be received in a wireless manner within a certain range; and through a data acquisition and debugging device with videos, the wireless data and real images can reappear synchronously, and technical experts in a factory can analyze the tower crane work more conveniently and intuitively.

Description

technical field [0001] The invention relates to tower crane remote control technology, in particular to a tower crane remote control method and system. Background technique [0002] At present, the controllers used by various manufacturers on tower cranes collect the working data of tower cranes in the following ways as the basis for debugging and service: one is the wireless wide area network communication method represented by GPRS and 3G. Data collection is carried out through the mobile network base station and the server. Due to the limitation of data flow, the data upload cycle is relatively long; the other is the field bus method represented by CAN bus. By reserving the test interface on the tower crane, data storage and reading can be performed by connecting the CAN bus adapter and data acquisition module; [0003] The disadvantage is that for GPRS and 3G communication methods, it is easily affected by geographical location, delay, data discontinuity and other facto...

AI Technical Summary

Problems solved by technology

[0003] The disadvantage is that for GPRS and 3G communication methods, it is easily affected by geographical location, delay, data discontinuity and other factors, so the data it collects cannot reflect the working status of the tower crane in real time

Its data monitoring is only suitable for detecting the alarm status rather than the working status; for the CAN bus communication mode, it needs to be equipped with a bus adapter, and the components need to be disassembled on the tower crane, so the work needs to be suspended for detection at the construction site, which affects the actual use of users; Under actual working conditions, the curve transformation cannot follow certain rules, so the machine parameters (pressure, flow, speed, etc.) alone cannot accurately reflect the actual operation situation, so it is difficult to match the actual data without image comparison
