The utility model provides a relay double break dynamic driving circuit with a frequency detection function, mainly solving the problems that the conventional driving circuit adopts a capacitance charge-discharge manner, and has factors of poor antijamming capability and the like, so that a hidden trouble can be produced to safe operation of a railway. The relay double break dynamic driving circuit has key points that the relay double break dynamic driving circuit takes a monostable trigger as a core component, a frequency range of a driving pulse can be identified, and only a driving signal within an allowable frequency range can drive a relay to act. The relay double break dynamic driving circuit disclosed by the utility model has the beneficial effects that double ends of a relay excitation coil are controlled at the same time, and frequency detection on a dynamic signal is realized by adopting a frequency discriminating circuit, and thus false operation of the relay can be guaranteed not to be caused at a non-working frequency, and antijamming capability is improved.
