- 1.地址缩短，同时加密(更有利存取数据库之间的数据) 2.图片上传功能，使用了保密上传目录功能，就算被上传*而不知道实际路径，*就不起作用了，还有就是上传使用了会员积分上传，积分的数目由管理员在后台设置 3.图片使用了防盗链功能，外部连接图片也使用了简单的防盗功能，本地图片使用了流方式防盗链功能 4.增加了在线邮件发送功能，(该功能目前只应用两个地方，斑竹申请和举报贴吧，只要有会员提交了信息，系统会自动发提醒邮件给管理员，该功能可以在后台实现关闭或启用，要正常使用该功能，服务器必须安装jma

- 飞行控制系统方案。整个系统由传感器组、飞控计算机、任务管理计算机、舵机、表决电路等主要部件和电源、外总线、通信设备、地面站等辅助设备组成。无人机、起落架、发动机、任务设备、燃油系统、环控系统等是被监控对象。其中，关键传感器采用相似或者非相似三余度；飞控计算机采用“主备备”式三余度飞控机算机；舵机采用二余度电动舵机；表决逻辑由高可靠性单余度数字逻辑电路和双路开关实现。-Flight Control System program. The entire system is composed of s
QQQQQQQPLC
- 可编程控制器PLC的应用绝大部分都是通过编写梯形图的方式实现程序控制的，但对于智能低压开关系统来讲，其分、断的控制往往要求由主控操作室远程控制来完成。按传统的方法，主控室要对某一个开关柜进行操作，须先发一个控制命令，PLC接收到该控制命令后，再由PLC程序执行该命令，该段程序必须用梯形图或逻辑指令编程，当开关柜数目巨大或要求多路设备同时控制时，PLC的程序编写就比较复杂，尤其是采用脉冲型输出控制而不是用电平保持型控制时更是如此。因为开关柜的分、合控制须两路继电器输出分别控制“分闸”和“合闸”，而

并行通信和串行通信介绍
- 并行通信和串行通信是CPU与外部设备之间进行信息交换的基本方法。采用并行通信时，构成一个字符或数据的各位同时传送，每一位都占用一条通信线，另外还需要联络以保证和外围设备协调地工作，它具有较高的传输速度。但由于在长线上驱动和接收信号较困难，驱动和接收电路较复杂，因此并行通信的传输距离受到限制，这种通信方式多用于计算机内部，或者作为计算机与近距离外围设备传输信息用。,Parallel and serial communication is communication between the CPU
