Summary:The invention discloses a passive communication method, a passive communication system and node equipment, and relates to the field of wireless communication. On the premise of not changing software and hardware of an object end node and not increasing the complexity of the object end node, a message to be sent is simultaneously and parasitically modulated on environment electromagnetic waves with multiple frequencies by utilizing the characteristic that equivalent impedance of two circuit structures such as a short circuit structure and an open circuit structure is irrelevant to the frequency, so that multi-frequency concurrent redundant parasitic transmission is realized; the bit error rate of the passive communication technology is reduced, the reliability of the passive communication technology is improved, and the anti-interference capability and the environment adaptability of the passive communication technology are enhanced while the power consumption of the object end node is ensured to be at an extr
