Abstract：In order to better achieve data collection and transmission，a Linux based multi-protocol gateway system was designed.The gateway included hardware circuits and software，withthe AM335X microprocessoras thecontrol core，to achieve thecolection of analogand digital signals，and output digital signals.The gatewaystatuswais displayed on the touch screen，and the sensor collcted data was uploaded to the server through Ethernet or 4G network，anembedded Linux operating system was chosen forthe software platform of a multi-protocol gateway to achieve various functions of the gateway.Theresultsshowedthat thenetwork communication was normal，the measurement error of voltage signal acquisition was within 0.03% ，and the measurement error of current signal acquisition was within 0.06% ，which meets the accuracy requirements for multi-protocol gateway use and has good practical value.
