  As a fourth-gen­er­a­tion light source based on the dif­frac­tion-lim­ited stor­age ring, Hefei Ad­vanced Light Fa­cil­ity (HALF) has higher re­quire­ments for mag­nets align­ment in ac­cu­racy, ef­fi­ciency, and re­li­a­bil­ity. In this paper, the Ref­er­ence Net­work of Align­ment (RNA) sys­tem is pro­posed to im­prove the mag­netic axis align­ment ac­cu­racy on the ra­dial di­rec­tion of the beam­line. Herein, we mainly in­tro­duce the con­cept de­sign and the the­o­ret­i­cal analy­sis of the RNA sys­tem, which cen­ter on the novel fu­sion method of sen­sors. A sim­u­la­tion re­sult shows that it is cred­i­ble to as­sume the RNA sys­tem can achieve an align­ment in­stal­la­tion ac­cu­racy of 20 µm and a dis­place­ment mon­i­tor­ing ac­cu­racy of 10 µm.
