PROBLEM TO BE SOLVED: To make it possible to perform update from an old system to a new system at a low cost.SOLUTION: A building monitoring system according to an embodiment comprises: a local control system which accommodates a node to be a monitoring target as a subordinate, on the basis of an updatable communication protocol; and a server for acquiring information on the node by communicating with the local control system. The local control system comprises: a first protocol processing unit; a second protocol processing unit; a validity determination unit; a synthesis unit; and an interface unit. The first protocol processing unit processes a first protocol that is one before update. The second protocol processing unit processes a second protocol that is one after the update. The validity determination unit determines validity of data received from the node by using the first protocol and data received from the node by using the second protocol. The synthesis unit synthesizes data aggregate from the data received by using the first protocol and data received by using the second protocol. The interface unit transmits the data aggregate to the server. |
