【Abstract】 The device with global positioning system (GPS) localization and communication with monitor and control center on construction machinery is a key equipment for construction machinery group management. According to the working particularity of the construction machinery, a dual-mode wireless network with global system for mobile communication (GSM) and wireless local area network (WLAN) is design ed. Using the embed ded computer as a hardware platform, a data acquisition card of GPS data and the important data of construction machinery is developed. Using embedded Linux sy stem as a software platform, a communication software is developed which can fre ely select GSM network or WLAN based on the network condition. With the above ne tworks, software and hardware, the key work of data transferring from single con struction machinery to the monitor and control center is implemented.更多还原
