基于C++的IOT网关和平台1：github项目ctGateway

初级代码游戏的专栏介绍与文章目录-CSDN博客

我的github：codetoys，所有代码都将会位于ctfc库中。已经放入库中我会指出在库中的位置。

这些代码大部分以Linux为目标但部分代码是纯C++的，可以在任何平台上使用。

源码指引：github源码指引_初级代码游戏的博客-CSDN博客

这是一个开源项目，LGPL许可。github位置：https://github.com/codetoys/ctGateway.git

支持Modbus等常见协议，可以定制上报规则和语法，可以扩展协议支持。主要是经过了工厂环境考验，基本架构稳定性比较好，程序该考虑的通用问题都考虑到了。

什么意思呢，意思是各种现场BUG都遇到了，都做了预防，作为一个通用的基础架构是比较理想的。

网关程序基于C++和linux，只需要基本的linux环境，附加依赖的东西都可以自行编译，可以交叉编译为arm，整个程序包括依赖的库不到10M，可以在很小的设备上运行。CPU占用率都测过了，很低（有些设备散热不好，CPU占用率要严格控制）。

网关嘛，一般是个控制台程序，没啥好看。配套的管理工具大概是这样的（就像个专有的MQTT客户端）：

这个工具很方便，所有网关支持的指令都支持，还支持通过MQTT远程执行指令和文件传输（也就是原本用telnet和ftp实现的能力在这个网关和工具上用MQTT实现了）。大部分指令也支持批量操作。

文档是比较多的，而且还在补充中，目前的文档是这些（就是项目根目录下的index.html）：

ctGateway

introduction 介绍

The gateway program is implemented in C++,Use the UTF-8 character set. 
Support Modbus and transparent transmission, MQTT and MQTTS. 
Log files and data files are limited in size to ensure that there is no disk full failure. 
The data is saved instantly to ensure not lost data when power lost. 
The data sequence number and confirmation mechanism ensure that there is no data loss from the gateway to the platform. 
The storage capacity of the network is different depending on the amount of data, and the gateway supports data compression. 
This program has been tested in harsh production environments in large quantities， 
Performance, stability, reliability, and environmental adaptability have all been verified.

网关程序以C++实现，使用utf-8字符集。 
支持Modbus和透传，支持MQTT和MQTTS。 
日志文件和数据文件大小受限，确保不出现磁盘满故障。 
数据即时存盘，确保断电不丢失。 
数据序号和确认机制保证网关到平台不存在数据丢失。 
断网存储能力取决于数据量，网关支持数据压缩。 
这个程序已经经过了大批量恶劣生产环境的考验。 
性能、稳定性、可靠性、环境适应性均经过了验证。

Quick Guide 快速指南

1. Compile and run 编译和运行

Linux or Linux virtual machine, MQTT broker(server), [Developer Guide](https://codetoys.github.io/ctGateway/doc/en/ctGateway_DeveloperGuide.htm) 
Linux 或 Linux 虚拟机, MQTT 代理(服务器), [开发指南](https://codetoys.github.io/ctGateway/doc/zh/ctGateway_DeveloperGuide.htm)

2. North Config MQTT config 北向配置 MQTT配置
