2. The PC end is complex in configuration and modification detection scheme, errors are prone to occur, one detection device needs to be configured with one computer, meanwhile, a large-screen display is matched, the cost is high, the modification detection scheme is long in time consumption, and the working efficiency is relatively low;

3. The technical specifications and the pattern specifications of the dual-mode communication units of the power grid company (national power grid and southern power grid) are different, the detection system can only detect the communication unit of a home appliance network company, and the flexibility and the replicability are poor;
