This invention relates to the field of traffic information engineering and control technology, and is a parallel dual-master redundancy switching system for track electronic actuators and its implementation method. The system includes a Series I track electronic actuator, a Series II track electronic actuator, and a wiring backplane. Both Series I and Series II track electronic actuators are plugged into the wiring backplane. By setting up a parallel dual-master redundancy switching system for Series I and Series II track electronic actuators, the track status information collected by both systems is the same when the two systems collect current, ensuring consistency. Moreover, the parallel dual-master redundancy switching system has the same matching impedance and consistent acquisition circuit parameters under different operating states such as dual-system and single-system (except when both systems are faulty), eliminating the problem of asynchronous states between the two systems after impedance matching, and reducing the influencing factors on the acquisition of track section status.

This invention relates to an ablation system, specifically to the field of ablation technology. The ablation system of this invention includes a cryoablation needle, which comprises an ablation needle body. The ablation needle body includes an inlet / outlet assembly. Through a moving mechanism or a matching cannula, the length of the ablation zone can be changed, allowing the same ablation needle body to accommodate ablation zones of various sizes. Therefore, the appropriate ablation zone size can be selected according to the size of the lesion. Thus, the cryoablation needle of this invention enables freezing and rewarming operations for lesions of various sizes, thereby reducing the number and types of cryoablation needles required and achieving cost reduction.
