Indoor distribution system, automatic switching method of indoor distribution system and storage medium

The invention provides an indoor distribution system, an automatic switching method of the indoor distribution system and a storage medium. The indoor distribution system comprises a baseband processing unit which is used for receiving baseband signaling and/or baseband data of a core network, processing the baseband signaling and/or the baseband data, converting the baseband signaling and/or the baseband data into optical signals and outputting the optical signals to a convergence unit; the convergence unit is used for distributing the optical signals to a first radio remote unit, and the first radio remote unit is further connected with a second radio remote unit; the first radio remote unit is used for receiving the first optical signal distributed by the convergence unit; a first radio frequency signal is transmitted according to the first optical signal; and under the condition that the working state of the first radio remote unit meets the unit switching condition, the first radio remote unit receives a
