A method for parallel monitoring of base station power sources, the method comprising: connecting a plurality of base station power sources in parallel, and interconnecting a monitoring unit of each base station power source with monitoring units of other base station power sources and connecting the monitoring unit with a network management device; characterized by: configuring one monitoring unit as host and the other monitoring units as slaves; each monitoring unit monitoring and managing the base station power source to which the each monitoring unit belongs, and the slave monitoring units transmitting preliminary management results needed to be uniformed or synchronized by a system arbitration to the host monitoring unit to apply for arbitration; the host monitoring unit performing system arbitration on the preliminary management results reported by the slave monitoring units and a preliminary management result of the host monitoring unit to obtain an arbitration result, and transmitting the arbitration result to the slave monitoring units; and the host monitoring unit and the slave monitoring units performing reloading according to the arbitration result; wherein the preliminary management results needed to be uniformed or synchronized by the system arbitration comprise battery expected states, and the step of performing system arbitration according to the obtained preliminary management results comprises: taking the last battery expected state as the system arbitration result; or the preliminary management results needed to be uniformed or synchronized by the system arbitration comprise voltage values expected to be output by rectifiers, and the step of performing system arbitration according to the obtained preliminary management results comprises: determining the system arbitration result using a principle of "taking the minimum value from all data" for a charge voltage and using a principle of "taking the maximum value from all data" for a discharge voltage; or the preliminary management results needed to be uniformed or synchronized by the system arbitration comprise current values expected to be output by rectifiers; and the step of performing system arbitration according to the obtained preliminary management results comprises: determining the system arbitration result using a principle of current-equalize or proportional current-equalize. connecting a plurality of base station power sources in parallel, and interconnecting a monitoring unit of each base station power source with monitoring units of other base station power sources and connecting the monitoring unit with a network management device; configuring one monitoring unit as host and the other monitoring units as slaves; each monitoring unit monitoring and managing the base station power source to which the each monitoring unit belongs, and the slave monitoring units transmitting preliminary management results needed to be uniformed or synchronized by a system arbitration to the host monitoring unit to apply for arbitration; the host monitoring unit performing system arbitration on the preliminary management results reported by the slave monitoring units and a preliminary management result of the host monitoring unit to obtain an arbitration result, and transmitting the arbitration result to the slave monitoring units; and the host monitoring unit and the slave monitoring units performing reloading according to the arbitration result; wherein the preliminary management results needed to be uniformed or synchronized by the system arbitration comprise battery expected states, and the step of performing system arbitration according to the obtained preliminary management results comprises: taking the last battery expected state as the system arbitration result; or the preliminary management results needed to be uniformed or synchronized by the system arbitration comprise voltage values expected to be output by rectifiers, and the step of performing system arbitration according to the obtained preliminary management results comprises: determining the system arbitration result using a principle of "taking the minimum value from all data" for a charge voltage and using a principle of "taking the maximum value from all data" for a discharge voltage; or the preliminary management results needed to be uniformed or synchronized by the system arbitration comprise current values expected to be output by rectifiers; and the step of performing system arbitration according to the obtained preliminary management results comprises: determining the system arbitration result using a principle of current-equalize or proportional current-equalize.
