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.
