英文摘要 | The invention relates to a wireless Hart adapter terminal communication method for combination of an industrial wireless network WIA-PA and a wired Hart adapter terminal. According to the present invention, after being subjected to electrifying and access network, a wireless node actively and periodically inquires address information of a Hart instrument connected with the wireless node until the Hart instrument responses, and stores the address information of the Hart instrument; with active and periodic inquiry of the corresponding Hart command through the Hart adapter by the WIA-PA network wireless node, the corresponding response information of the Hart instruments of various manufacturers is received in the wireless node, and is transmitted to the wireless gateway through the WIA-PA network, wherein the Hart instruments are connected with the adapter and have various functions; and the wireless node is adopted to actively upload the Hart instrument information, the upload is performed once every 1 second, and the wireless gateway in the WIA-PA network stores and real-timely updates the instrument Hart information so as to ensure the real-time property of the instrument Hart information in the host computer configuration software. |
