l Background
With the rapid development of the social economy and the telecommunications industry, telephones have become an indispensable communication method. However, as an instant communication tool, phone calls often lack the capability for retrospective review and analysis, which causes inconvenience for work review. This is especially critical in the transportation and railway industries, where accurate and reliable work records are essential.
The Railway Operations Center is the functional unit responsible for the daily management and operation of railway dispatch communications. It is mainly responsible for ensuring that railway dispatch commands are correctly issued and accurately implemented. The chief issue of command and dispatch is to ensure the integrity and reliability of communication system. Two-way radios serves as tools for transmitting and recording voice data have their performance, functionality, and stability directly impacting the safe operation of the railway.
