Disclosed are a non-to-the-home type device and method for detecting electric meter misconnection based on the PLC communication technology and using multiple frequencies. The detection device includes a master detection device and a slave detection device. The master detection device acquires address information of different electric meters at the outlet terminals of the electric meters by using RS485 communication. The modulation circuit modulates the communication address information of different electric meters into high-frequency carrier signals of different frequencies, and sends the high-frequency carrier signals to user sides by using the PLC communication technology. A line trap is provided between the modulation circuit and the electric meters. The slave detection device has a high-frequency carrier signal detection antenna. The user side detects the high-frequency carrier signal, demodulates the high-frequency carrier signal to obtain the high-frequency carrier signal frequency and the communication address information of the electric meter corresponding to user.
