Design And Implementation Of Logistics Self-Pickingup System Based On GMS

In recent years,E-commerce has been expanded and developed,causing express industry to increase rapidly;also,more and more merchant accessed express industry.The number of express parcels is increasing exponentially,resulting in that the problem of “Last-Mile” delivery which couriers can’t deliver and recipients can’t sign for parcels normally becomes prominent.However,as a new product,intelligent logistics self-pickup and delivery system greatly decreases the contradiction between couriers delivering and recipients signing in.At present,the most of operational logistics self-pickup and delivery system provide paid service in market,increasing the burden of couriers and recipients and harming to effectively solve the problem of “Last-Mile” delivery.From the point of social benefit of serving the public,this dissertation puts forward a low-cost production,low-power operation and free logistics self-pickup and delivery system based on GSM considering of production cost,reliable performance and composite purpose,in order to effectively solve the problem of “Last-Mile” delivery which iscouriers and recipients delivering and picking up express parcels and promote E-commerce and express industry to have benign development further.This dissertation elaborates on fundamental principles,design and implementation in detail,and puts forward the general scheme on the system hardware and software in strictaccordance with single-chip microcomputer system standards and by means of comprehensive design in function demand analysis,components choice,circuit structure and writing program.Meanwhile,various functions are realized with communication protocols and circuit modular design.On this basis,the various functions of modules are tested and the system appearance is designed.Finally,the shape of logistic self-pickup and delivery system is cabinet structure,electric control locks are used to command that when system cabinet doors open or close.Only if couriers deliver express parcels normally,the system will open and close cabinet doors.When couriers deliver express parcels,control system transmits the signals of delivering collected by irradiation infrared sensors to communication module,and the information of parcels is sent to recipients via mobile network.When picking up parcels,recipients input verification passwords and take parcels away easily.Meanwhile,system controller are networked to the monitoring computers of property management department through communication transmission protocols,and the monitoring computers can inquire of operational situation of the system,including whether parcels are in cabinets,how many parcels are in cabinets,whether parceled are overdue and so on.
