Communication signal monitoring system and method based on big data

The invention discloses a communication signal monitoring system and method based on big data, and the method comprises the steps: constructing a first model and a second model in a wireless network communication network composed of a plurality of wireless network transmitting terminals, obtaining the received signal strength alarm information of a receiving end device in the wireless network communication network, and transmitting the received signal strength alarm information to a server; comparing the received signal strength predicted value with the received signal strength measured value, judging whether the target equipment is subjected to co-frequency interference or not, calculating a first minimum coverage range of a wireless network transmitting terminal which affects the target equipment, judging whether the first minimum coverage range meets an adjustment requirement or not, further judging whether an alternative frequency band can be selected or not, and judging whether the target equipment is su
