Intelligent control system and method for complex ground beam field rail intersection Technical Field The invention relates to the technical field of foundation engineering, in particular to an intelligent control system and method for crossing a track of a complex ground beam field. Background In the production operation process of the bridge precast beam field, the travelling crane and the transportation Liang Tuoche are two types of core transportation equipment which respectively run by depending on an independently arranged track system. The travelling crane generally moves longitudinally and transversely along the high-altitude track and is responsible for hoisting, shifting and stacking the beam body, and the carriage Liang Tuoche horizontally transports the beam body along the ground track to realize the circulation among working procedures. Because the beam field operation area has limited space and compact layout of each functional area, the running rail and the trailer rail often have plane or vertical intersection, and a device passing conflict point is formed. The cross running of the travelling crane and the trailer in the existing beam field mostly adopts a manual dispatching or simple mechanical limiting mode. However, the prior art has the following problems: the manual dispatching efficiency is low, and the passing conflict is easily caused by human errors, so that the bridge production progress is influenced. The simple mechanical limit needs manual operation to switch the track, and cannot adapt to the high-frequency cross operation requirement under complex terrain. The lack of accurate in-place monitoring and safety locking mechanisms is insufficient in operation safety, and equipment collision risks are easily caused. The traditional power supply mode is easy to generate unstable power supply during cross operation, and continuous operation of equipment is affected. In summary, the existing traditional cross traffic control mode relying on manual scheduling and simple mechanical limiting has obvious defects in the aspects of efficiency, safety, automation degree and operation stability.
