夜光精讲 Opentcs 框架与实际AGV方案（二）

夜光序言：

 

 

 

A little more persistence, a little more effort, and what seemed hopeless failure may turn to glorious success

再多一点点毅力，多付出一点点努力，看似无望的失败也会转化成辉煌的成功。

调度系统与机器人的通讯

任何系统与实体之间通讯都需要协议，调度系统与机器人的通讯通过Ｋｅｒｎｅｌ中的Ａｄａｐｔｅｒ实现，信息传输格式采用ＪＳ０Ｎ格式，数据交换的载体为Ｒｅｄｉｓ数据库。

 

调度系统通过Ｋｅｒｎｅｌ的Ａｄａｐｔｅｒ向Ｒｅｄｉｓ服务器发送运输订单信息，而该信息由客户的ＭＥＳ系统生成，通过通讯协议存放到Ｒｅｄｉｓ服务器中，供Ａｄａｐｔｅｒ从中取用，Ａｄａｐｔｅｒ获取到订单后会计算出该订单的静态路由，以及路由成本，从而选择最优路径，并为该车匹配，将携带路由命令的订单存放到Ｒｅｄｉｓ服务器，并从Ｒｅｄｉｓ服务器中取回移动机器人的状态信息，在客户端Ｖｉｅｗｅｒ上显示。

 

ＪＳ０Ｎ 格式样例：
