The invention discloses a current differential protection service 5G time service terminal performance monitoring and evaluation method, and relates to the field of 5G communication. According to the specific implementation scheme, the Beidou high-precision time probe device is connected to a network, a Beidou satellite signal is received through a Beidou receiver module, the received Beidou satellite signal is processed, and a high-precision time signal is output; the main processing module receives a high-precision time signal, a probe message of the 5G time service terminal and a time service signal of the 5G time service terminal, measures time deviation information, analyzes probe message data and calculates channel time delay information through a channel time delay calculation process; and based on the channel time delay information and the time deviation information, evaluating a bidirectional time delay asymmetry degree, and summarizing and processing the information. The time deviation of the 5G tim
