The utility model discloses a crane data acquisition unit based on GPRS (general packet radio service) communication. The crane data acquisition unit comprises a microcomputer processor, a power supply module, an isolation communication module, a memory module for storing the acquired crane work state data, and a GPRS wireless communication module for being communicated with a GPRS wireless network, wherein the isolation communication module, the memory module and the GPRS wireless communication module are respectively connected with the corresponding interfaces of the microcomputer processor; and the microcomputer processor acquires the work state data of the crane through the isolation communication module, and stores the acquired data in the memory module in a specific data format so as to transmit the data to a remote terminal through the GPRS wireless communication module. The crane data acquisition unit provided by the utility model can realize reliable wireless transmission of the work state data of crane equipment through a public GPRS network at a lower cost, thereby providing convenience for further storage and analysis of the acquired crane work state data.
