Based on 32 Tons Crane for Wireless Remote Control System Design

In this article, by using the main feature and principle of Nordic VLSI Company¿s nRF905 launch reception unit and PHILIPS Company¿s P89LPC932 Flash SCM, to achieve the high reliability of Crane wireless remote control. It has developed a vehicle of high-reliability wireless industrial remote control device. 50-200 meters from the remote control can be a reliable work. SCM P89LPC932 through the I/O port control of the nRF905 working state, frequency and transmitting power, and other parameters. And it can realize the diplex operation. This article has given the wireless communication receiving and dispatching software flow chart. As a result of the use of nRF905 launch unit, it can choose access, especially when there are many cranes around at the same time. The device is mainly design for the crane which the rotor resistance is series 5-6-governor. As for other types of Crane, the electrical resistance of the rotor speed string of programmed just a little software design changes to achieve the purpose of remote control. The design may be extended to other remote control devices.
