[通讯编程] MODBUS协议中文版

MODBUS协议支持传统的RS-232、RS-422、RS-485和以太网设备。许多工业设备,包括PLC,DCS,智能仪表等都在使用Modbus协议作为他们之间的通讯标准。 Modbus 协议是应用于电子控制器上的一种通用语言。通过此协议,控制器相互之间、控制器经由网络(例如以太网)和其它设备之间可以通信。Modbus 协议定义了一个控制器能认识使用的消息结构,而不管它们是经过何种网络进行通信的。它描述了一控制器请求访问其它设备的过程,如何回应来自其它设备的请求,以及怎样侦测错误并记录。它制定了消息域格局和内容的公共格式。
The MODBUS protocol supports traditional RS-232, RS-422, RS-485, and Ethernet devices. Many industrial devices, including PLC, DCS, and intelligent instruments, are using the Modbus protocol as a communication standard between them. The Modbus protocol is a common language applied to the electronic controller. Through this protocol, controllers can communicate between each other and the controller via a network (such as Ethernet) and other devices. The Modbus protocol defines a controller that recognizes the message structure used, regardless of what network they communicate. It describes how a controller requests access to other devices, how to respond to requests from other devices, and how to detect errors and record. It formulates the public format of the message domain pattern and content. (2018-03-22, C/C++, 998KB, 下载3次)

[通讯编程] Tringulationalgorithurcecode

逐点插入的Lawson算法是Lawson在1977年提出的,该算法思路简单,易于编程实现。基本原理为:首先建立一个大的三角形或多边形,把所有数据点包围起来,向其中插入一点,该点与包含它的三角形三个顶点相连,形成三个新的三角形,然后逐个对它们进行空外接圆检测,同时用Lawson设计的局部优化过程LOP进行优化,即通过交换对角线的方法来保证所形成的三角网为Delaunay三角网。
Point by point inserted Lawson at Lawson algorithm is put forward in 1977, thinking that the algorithm is simple, easy to program implementation.
