The Design And Research Of A Low-power Network Control Mail System

E-commerce promotes the development of logistics warehousing,transportation and other related industries.There are many services based on Online to Offline platform,such as take-out food,clothing delivery.They are also need the support of logistics.Customers and delivery staffs' time and space is difficult to match,making the terminal distribution inefficient.The purpose of this thesis is to design a low-power network control mail system to solve this contradiction,reduce unnecessary waiting time,make it more efficient and brief.the research mainly includes:1.Analyze the requirements of the Network Control Mail System,design the system's work flow and hardware software scheme.2.Select MSP430 as the control core of the box,Si4432 for the box and gateway communication RF chip,complete the design of low-power circuit.3.Transplant and improve the embedded operating system ? C/OS-?,reduce the operating power consumption of the operating system,and reduce the wake-up time of the RF Soc module.Use the idea of DPM to design a low-power operating mode.4.Use the SSI framework to build the system server.System server communicate with gateway through the WebSocket technology.Complete the system's performance test and power consumption experiment.After the test,the system can run normally and maintain very low power consumption.Using 3 dry batteries power supply,it can work for about 900 days.
