初步实现了一个聊天界面，和一个心跳服务器。在线的用户的IP地址都会被心跳服务器收录。不同的在线用户又能通过心跳服务器获取在线用户IP列表。-Initial realization of a chat interface, and a heartbeat server. Online user' s IP address will be included heartbeat server. The online user can get through the heartbeat serve

现P2P的简单通信 包括心跳检测 掉线处理等功能-implement the communication between 2 peers-P2P communications is now a simple heartbeat dropped, including processing and other functions-implement the communication between 2 peers

带有心跳报文的程序 是模拟的 利用的是多线程 来进行模拟的 利用了定时器-Program with a simulated heartbeat packets using a multi-threaded to simulate the use of a timer

脉搏上位机程序，可以自动检测人的心跳并进行分析和画图显示。-Pulse PC program, can automatically detect human heartbeat and carries on the analysis and drawing display.
