Method for automatic setting of wireless gateway register mapping table

Abstract

The method for automatically setting the wireless gateway register mapping table relates to the parameter setting technology of the gateway, in particular to the method for automatically setting the parameters of the wireless gateway used in the detection and monitoring system of the railway transport LNG container. The wireless gateway is connected to a computer that stores and sets the gateway information, sets the parameter storage area and the flag position in the wireless gateway, adds a parameter writing module in the computer, and adds a start-up inspection module in the wireless gateway. The method includes the following steps: A, computer reading Information, B, write the read information into the parameter storage area, C, set the flag, D, restart the wireless gateway, the wireless gateway judges the flag, if the flag is not set, go to step F, otherwise, execute step E, E. Read the information in the parameter storage area and write the information into the actual storage area of ​​the gateway parameters, clear the flag bit, F, execute the normal start-up procedure. Using this method can reduce the workload and avoid errors in the process.

Description

technical field [0001] The invention relates to a parameter setting technology of a gateway, in particular to a method for automatically setting parameters of a wireless gateway used in a detection and monitoring system of a railway transport LNG container. Background technique [0002] WirelessHART is the first open, interoperable wireless communication standard to address the process industry's critical need for reliable, robust and secure wireless communication in real-time plant applications. [0003] After voting by 29 countries, the WirelessHART communication specification (HART7.1) was officially approved by the International Electrotechnical Standards Committee (IEC) on September 19, 2008, and became a publicly available specification (IEC / PAS62591Ed.1). This standard is indeed the first industrial wireless communication technology in the world to obtain this level of international certification. [0004] The WirelessHART communication standard builds on existing fi...

Problems solved by technology

[0018] In "A Monitoring System for LNG Tanks During Railway Transportation", the information of LNG tanks has been stored in the computer of the monitoring center, and the information has included the information of wireless devices, that is to say, all the wireless devices configured with WirelessHART gateways The required information already exists in the computer connected to the gateway, but the existing technology does not support automatic configuration of the information to the gateway (automatic configuration of the wireless gateway register mapping table), and it is necessary to use special software to manually input one by one
