Abstract
At present, in many large supermarkets, the trolley management mainly rely on manual, which increases management costs and the burden of work, therefore, the supermarket trolley positioning system is proposed to solve this problem. The positioning system takes full advantage of ZigBee technology’s low power consumption, low cost and ad hoc network, the node module is embedded into the supermarket trolley and positioned by positioning engine, using PC interface developed by VB6.0 to display its real-time position. Field experiments show that its positioning accuracy is less than 3m, The staffs easily know the location of trolleys when they sit in the monitor room. It can reduce the costs and the burden of work.
