Compared with the prior art, the invention has the advantages that through the damping system based on the house beam node, whether the damping unit needs to be adjusted or not is determined by comparing the pressure value of the received pressure sensor with the preset value, if the pressure value is lower than Pa1, the pressure value possibly comes from artificial jumping or falling of objects, the damping unit does not need to be started to damp within a controllable range, if the damping unit needs to be adjusted, the controller compares the distance of the second distance sensor received in real time with the distance detected by the third distance sensor, the thrust of the first electric push rod and/or the second electric push rod and/or the third electric push rod is determined according to the comparison result, and the magnitude relation between the real-time distance detected by the second distance sensor and the real-time distance detected by the third distance sensor is determined, the electric push rod needing to be adjusted is judged, the thrust of different electric push rods is determined according to the difference value, different thrust is determined through different difference value ranges, and the buffering effect of the electric push rod in the damping unit and the buffering cushion and the rubber ring arranged in the damping unit is adjusted, so that the system can achieve the maximum damping effect by using the minimum force, and the damping capacity and the damping efficiency of the system are improved.
Particularly, the system determines the electric push rod to be adjusted through the real-time distance between the third fixed block and the second wedge block transmitted by the second distance sensor arranged on the third fixed block and the real-time distance between the third fixed block and the first wedge block transmitted by the third distance sensor, if the real-time distance detected by the third distance sensor is smaller than the real-time distance detected by the second distance sensor, the first wedge block is extruded, the third electric push rod is started to generate acting force on the first wedge block, so that the pressure applied to the first wedge block is reduced, the distance between the third fixed block and the first wedge block returns to the initial distance, and meanwhile, the distance between the third fixed block and the second wedge block also gradually returns to the initial distance, and the damping efficiency and the damping effect are improved.
Especially, if the controller judges that the real-time distance between the third fixed block and the second wedge is smaller than the real-time distance between the third fixed block and the first wedge, the second wedge is extruded, the second electric push rod needs to be started to generate a reaction force on the second wedge, meanwhile, the first electric push rod is started to reduce the extrusion on the second wedge, and the first electric push rod and the second electric push rod are adjusted, so that the adjustment coefficient of the thrust on the first electric push rod and the second electric push rod is smaller, the excessive adjustment is avoided, and the adjustment efficiency and the shock absorption effect of the system are improved.
Especially, if the real-time distance between the third fixed block and the second wedge block is equal to the real-time distance between the third fixed block and the first wedge block, it indicates that the acting forces applied to the first wedge block and the second wedge block are equal, but at this time, under the condition that P > Pa2, the controller determines the thrust of the second electric push rod and the third electric push rod according to the difference between the distance of the first distance sensor and the initial distance, so as to synchronously weaken the acting forces applied to the first wedge block and the second wedge block, so that the system can weaken the vibration force applied to the system through the acting forces of the second electric push rod and the third electric push rod in a balanced state, and improve the damping capacity of the system.
