The invention relates to a module powered detection device based on a ubiquitous power Internet of things intelligent electric energy meter. The device comprises a circuit board, wherein the circuit board comprises a switching power supply, a first management chip module interface, a second management chip module interface and a control chip. The circuit board comprises a first power supply circuit and a second power supply circuit. An upper computer is connected with the control chip. The device has the advantages that management chip modules are fixed through utilization of the first management chip module interface and the second management chip module interface and; a PF signal and a CLK signal are transmitted to the first management chip module interface through utilization of the control chip, so the whole device can carry out a function test on the management chip modules; a synchronous signal and a management chip module plug-in and pull-out signal are transmitted to the secondmanagement chip module i
