The invention belongs to the field of electronic detonator wire testing, and particularly relates to a multi-node load testing system based on 485 communication and relay application, which comprises an upper computer, the upper computer is in signal connection with a test host module; the test host module is connected with a plurality of communication wire switching modules through signals; the plurality of communication wire switching modules are sequentially connected in series; the communication wire switching module located at the tail end is connected with a plurality of module terminal testing devices through signals, and meanwhile the module terminal testing devices monitor bus commands to start timing monitoring of the detonation state of the module in a matched mode. After the test is completed, the test host obtains test data from the module terminal test equipment through 485, a test conclusion is output through analysis, the test environment of the test equipment is completely equivalent to a rea
