CC1101-based anti-overwinding alarm device with multiple parallel cranes

Abstract

The invention relates to a CC1101-based anti-overwinding alarm device with multiple parallel cranes, and relates to the field of crane safety. The CC1101-based anti-overwinding alarm device comprisesa transmitting terminal device and a receiving terminal device, the transmitting terminal device comprises a microcontroller module, a CC1101 wireless communication module, an overwinding detection module, a solar cell module and a power management module, and the receiving terminal device comprises a microcontroller module, a CC1101 wireless communication module, an overwinding processing and alarming module and a power supply management module. A receiving terminal is connected with an upper computer through a serial port and has a channel selection mode and a working mode. Compared with theprior art, the CC1101-based anti-overwinding alarm device has the advantages that multi-channel transmission is supported, the transmitting terminal device can automatically select a communication channel, the risk of collision due to the fact that multiple devices send signals at the same time is avoided, and the transmitting terminal device uses a solar power supply manner, so that the servicelife is prolonged, pollution is reduced, and the working efficiency is guaranteed.

Description

technical field [0001] The invention belongs to the field of crane safety, and in particular relates to a CC1101-based anti-rolling alarm device for multiple cranes in parallel. Background technique [0002] Cranes are very important means of transportation in construction units, and their safe and efficient operation is the guarantee for the safety of production and construction personnel. In order to avoid frequent crane accidents, the government has issued relevant national standard documents, such as "Safety Monitoring and Management System for Hoisting Machinery" GB / T28264-2017, which mentions one point: the need to strictly monitor the over-rolling of cranes. When the crane is performing heavy lifting operations, if it encounters an over-rolling situation, it is necessary to transmit the over-rolling information to the operating room in real time, so that the staff can deal with it in time to ensure the safe operation of the crane. [0003] In the early days of the cr...

Problems solved by technology

[0006] The present invention uses a frequency division method to solve the signal collision problem, and the maximum number of available channels is 256, and the receiving end equipment has a channel selection mode and a working mode

In the channel selection mode, the channel is selected by the operator through the host computer. At the same time, the receiver device will send a channel selection signal to the transmitter in the preset channel, and the transmitter receives this signal and uses it to select The corresponding channel effectively solves the problem of channel configuration of the transmitter equipment, saves manpower and improves work efficiency;
