Example Embodiment

[0016] The amplitude sensor is connected to the tower crane trolley motor, and the angle sensor is connected to the tower crane rotation transmission gear through an encoder.

[0017] The liquid crystal display adopts an industrial-grade 10.4-inch 800×600 pixel 65K color TFT color super large liquid crystal display.

[0018] The ZIGBEE module adopts the ZICM2410 communication module with a working frequency of 2.4 GHz, which has strong anti-interference ability.

[0019] The microprocessor module is electrically connected to the key input module and the sound alarm module, and is connected to the liquid crystal display and the ZIGBEE module through the RS232 module.

[0020] After the signals detected by the amplitude sensor and the angle sensor are filtered, isolated and amplified by the signal conditioning module, the analog signal quantity is input to the A / D pin of the microprocessor module.

[0021] The microprocessor module performs A / D conversion on the collected sensor values ​​...

Abstract

The invention relates to a technology of remote monitoring of tower crane security, in particular to a method and device for preventing collision in the tower crane cluster operation. The anti-collision device disclosed by the invention consists of a microprocessor module, an amplitude sensor, an angular sensor, a signal conditioning module, a keystroke input module, a voice alarm module, an RS232 module, a liquid crystal display and a ZIGBEE module; before the tower crane is subjected to anti-collision judgment, the microprocessor module acquires the tower crane information through the amplitude sensor and the angular sensor, and acquires the anti-collision information through the ZIGBEE module, and then omni-directional safety monitoring aiming at anti-collision in the tower crane cluster operation can be realized through the judgment of three given judging methods, thus collision accidents are effectively avoided.

Description

technical field [0001] The invention relates to a technology for remotely monitoring the safety of tower cranes, in particular to an anti-collision method and device for tower crane cluster operations. Background technique [0002] The existing tower crane safety monitoring can only realize the collection of signals such as load, wind speed, angle, amplitude, height, etc., and does not have the anti-collision function of tower crane cluster operation. Although two integrated tower crane cluster operations have appeared on the market in recent years The monitoring device with anti-collision function, but because of its single anti-collision judgment method, it is only based on whether there is a trolley entering the intersection area formed by the rotation of the booms of the two tower cranes to judge whether it is necessary to issue an alarm, and ignores the In other cases, the boom and the trolley may collide, so it is impossible to realize real and effective safety protect...
