为解决传统 HART 仪表内数字信息不能被有效利用的问题，提出一种使用 WirelessHART 适配器对 HART 仪表进行升级的低成本方案。该适配器兼容有线 HART 协议和 WirelessHART 协议，其主要工作是获取 HART 仪表内的组态参数、过程参数、诊断以及校准等数字信息，并采用 Wire-lessHART 协议将获得的数据发送至 WirelessHART 网关，实现传统 HART 仪表和控制系统之间无线、双向数字通信。文中详细描述了该适配器的硬件设计原理和软件设计步骤，并给出开发原型的通信测试结果。

In order to solve the problem that digital information in traditional HART instruments couldn’t be used effectively, a low cost solution is presented to upgrade traditional instruments by using the Wire-lessHART adapter. The adapter is compatible with HART protocol and WirelessHART protocol, and its main job is to obtain digital information of configuration parameters, process parameters, diagnosis and cal-ibration in HART instruments, then the adapter using the WirelessHART protocol sends these data to WirelessHART gateway. The adapter can realize bi-directional wireless digital communication between tra-ditional HART instruments and control system. This paper describes the adapter’s hardware principle and software design procedure, and the testing results for prototype communication are given.
