OTO Catering App Real-time order logistics Tracking System Architecture Design (i)

1. Introduction . 1 1.1 Purpose

Whether it is Amoy point or hungry, as long as it is intended to do the takeaway app, I think there is no real-time map to show the location of the takeaway order information is not justified, because I think that the delivery of real-time logistics is very harsh. 11:00 the sale at 12:00 has not been sent to the user, are not forgiven.

Based on this I would like to design a map real-time display of the delivery Agent location information System.

2.1 Functional Requirements

The main functions of the system include:

1). After receiving the order, the Distributor app logs in and sends its location information to the server management.

2). The user client can view the real-time location information on the map after the order has been transferred to the distribution clerk.

3) The server receives the distribution Clerk location information and forwards it to the corresponding user client according to the delivery order information.

4) Other functions. After the user app submits the bill of lading to the Web server, the Web server pushes the message to the Order tracking server

3.1 Business Process Design

   

4.1 Interface Design

1) Store version

     

2) Distribution Clerk

  

5) Detailed design and implementation of each module

5.1 User app request geographic location

public class Myudpclient extends Udpclientbase {public myudpclient (byte[] uuid, int appid, String serveraddr, int serv

		Erport) throws Exception {super (UUID, AppID, serveraddr, ServerPort);
		} @Override public Boolean hasnetworkconnection () {return util.hasnetwork (onlineservice.this);
		} @Override public void Trysystemsleep () {tryreleasewakelock ();
			@Override public void onpushmessage (Message message) {if (message = = null) {return;
			} else if (message.getdata () = = NULL | | message.getdata (). Length = = 0) {return;
			} else if (message.getcmd () = =) {//0x10 general push Information} else if (message.getcmd () = =) {//0x11 group Push Information}
				else if (message.getcmd () = = +) {//0x20 custom push information String str = NULL;
				try{str = new String (Message.getdata (), 5,message.getcontentlength (), "UTF-8");
				}catch (Exception e) {str = Util.convert (Message.getdata (), 5,message.getcontentlength ());
}//converted to JSON string lbs real-time logistics chase,				Gson Gson = new Gson (); 
				Msgtype Msgtype = Gson.fromjson (str,new typetoken<msgtype> () {}.gettype ());
				if (Msgtype.equals ("Wuliu")) {//Distribution Agent address location} else if (Msgtype.equals ("Order")) {//Order confirmation}
				else {Notifyuser (32, "Custom push Information", "" "+str," receive custom push Information ");
		}} setpkgsinfo ();
 }
