Abstract: The critical information collection and transmission system of hoist brake system is designed based on computer communication technology and automatic control technology to remote monitor the operating state of hoist brake system real-timely and improve the operation safety of lifting equipment.The overall structure of collection and transmission system which have C8051 micro-controller to be core is elaborated. The method of micro-controller controlling collecting multi-channel data acquisition of key signal and completing GPRS wireless network communication and data transmission via the serial port,the collected data will be processed and stored in the remote data system.Signal collecting and sending synchronization have been achieved by using C8051 micro-controller,the hoist brake parameter could be captured accurately which provides accurate data for remote monitoring and fault diagnosis system.

Key words: Hoist Brake System, Micro-controller, Data Collecting, Remote Network
