The Research And Design Of Customer Service Express Terminal System

At the present time, with the rapid development of the economy, the contribution rate of express delivery industry to world economic growth is more obvious. Express industry development space is extremely broad. A large number of express delivery companies enter the Chinese market, many domestic express enterprises will face increasing keen competition and its service has penetrated into people's daily life. At present, domestic consumers complained mostly about the delay of express, the defection of express and the quality of services, etc. To remedy this situation, the paper researches and designs express terminal services system, it achieves express automatic access and saves the time of a sure receipt, effectively improves service efficiency.The express mail service system will be placed in residential communities, universities these population cexters. It takes the shape of some small lockers and electronically controlled lock controls on and off. Only access to parts in the normal time, the system will switch the door. When express courier deposits express, the control system will capture and identify the bar code. After identifying the bar code number will be sent to the customer through the short message. Customer enters the correct bar code number will easily extract the express. By analyzing, the system structure is divided into bar code read and recognition, express box control and short message communication these three subsystems.The paper main work is to analyze and design the structure of terminal customer service system. The hardware system is mainly composed of Microcontroller which is the core processor hardware and together with other functional device. The main functional program module of the software will be design in order to meet the system main function.The paper accomplishes the main functional design of express terminal customer service system. The hardware of Bar code reading and recognition subsystem is designed to the circuits of basing on processor and CMOS image sensor. The paper uses image processing technology for the bar code on the threshold division, filtering, positioning, inspection of the image edge. The code identification takes the projection method for the statistical analysis to pixel, recognizes the bar code words information. The paper adopts electronically controlled lock to control open and close. Through procedures for the express searching work, it completes express access. Short message communications achieves in the way of GSM module. It would meet expected functional demands.
