为解决串行设备的网络化控制问题,必须以某种方式实现串行通信与网络通信的协议转换。新兴的设备服务器技术在串口设备和网络之间架起了桥梁,能方便的实现两者的协议转换。针对某型号电视发射机的远程控制项目,引入设备服务器作为网关,编程实现了基于Web的远程控制系统开发,描述了系统的总体结构、软件架构以及安全机制等问题。实践证明,该方案以极小的代价即可实现串行设备的远程控制,且简单、安全。
In order to solve the problem of networked control of serial devices, the protocol conversion of serial communication and network communication must be implemented in some way. Emerging device server technology in the serial port between the device and the network bridge, can easily achieve the conversion between the two protocols. Aiming at the remote control project of a certain type of TV transmitter, the device server is introduced as a gateway, and the development of a web-based remote control system is programmed. The overall structure, software architecture and security mechanism of the system are described. Practice has proved that the program at a very small price to achieve remote control of serial devices, and simple and safe.
