Abstract


With advances in technology, economic development, the indoor positioning systems are currently in constant development stage. People on the positioning and navigation increasing demand, particularly in complex indoor environments, often need to determine the mobile terminal or the holder of the indoor location information. This paper studied the S-ID is a combination of indoor positioning systems using infrared and ultrasonic technology, through infrared ultrasonic distance measurement principle to achieve trilateral positioning. This technique reduces the single and separate use of ultrasound technology shortcomings of using infrared technology, improves the positioning accuracy of the positioning range expanded. Logistics Laboratory is to achieve product out of storage, storage, distribution, transportation and other third-party professional logistics process simulation, build a logistics center has become the core of the supply chain experimental teaching platform. This paper describes the characteristics of university laboratories and logistics functions, including logistics laboratory hardware and software system configuration and implementation features. Then introduced indoor positioning systems, and S-ID positioning system hardware structure, the realization principle and measurement principles were studied, highlighting the S-ID system positioning features. The system then focuses on the application of the basic logistics laboratory work processes to achieve positioning and communication systems and monitoring application of the principle out of storage, distribution and other process. Laboratory reference time signal receiver on infrared transmission interval, the moving object is positioned carrying the infrared transmitter signal is received after emitting an ultrasonic wave outward, when the ceiling receiver has three or more of the receiver When the ultrasonic signal is received, the position of the moving object can be measured. Final analysis of S-ID positioning system results in the logistics laboratory applications and system performance, the system has the advantage that the prospect S-ID systems and potential applications. Studies and experiments show that, S-ID System in Logistics Laboratory in nicely simulates the GPS navigation system. Laboratory system to track the whole process of the entire logistics operations, enabling managers through the computer to complete all the processes and improve operational efficiency. Therefore, S-ID system in the logistics laboratory applications more worthy of our study, it is worth digging its potential functions. By studying Logistics Laboratory S-ID system applications to discover practical problems and shortcomings of the system in the practical application of theoretical basis.
