The invention discloses an automatic scoring system for martial art competitions and a scoring method thereof. The invention belongs to the field of martial art competition scoring. The invention discloses an automatic scoring system for martial art competitions and a scoring method thereof. Actual hitting force and the like are fed back into actual data through the sensor, and scoring is carriedout in cooperation with the scoring condition of a referee; scoring results are more accurate, errors are reduced, a contact force net and a bubble partition wall are distributed, the action range andstrength of the striking force are effectively recorded, the score can be judged more accurately according to the striking force of the pressure sensor, the accuracy of the scoring system for the martial art competition is effectively improved, and when being hit, the plurality of spherical force-reducing bubbles move to a certain extent to present a micro dynamic state, so that the action rangeof the force can be expanded, the absorption of the hitting force is realized, the local force of the hitting force acting on the body of the player is effectively reduced, the player is effectively protected from being easily injured, and the potential safety hazard is reduced.

The invention discloses a novel aluminum alloy cable bridge frame. The novel aluminum alloy cable bridge frame comprises a bridge frame body, a split supporting structure, a bridge cover, a first heatdissipation structure, a plate frame, reinforcing structures, a second heat dissipation structure and a moisture absorption and damp-proof structure. According to the novel aluminum alloy cable bridge frame, interior separation and indirect reinforcing support of a U-shaped groove plate are realized through the split supporting structure; while different cables can be placed in a classified mode,the interior of the U-shaped groove plate is reinforced; due to the arrangement of reinforcing ribs, the situation that the bending positions of side plates of the U-shaped groove plate are deformeddue to external force is effectively avoided; the overall pressing reinforcement on the side surfaces of the U-shaped groove plate is realized through the reinforcing structures; rapid heat dissipation cooling in the bridge frame body is ensured through the first heat dissipation structure and the second heat dissipation structure; meanwhile, dust filtering is also taken into consideration; and efficient moisture absorption drying of the interior can be realized through the moisture absorption and damp-proof structure, so that all-directional protection of a cable is realized, the maintenanceburden of personnel is reduced, and the service life of the cable is prolonged.

A multi-services IP bearer system having QoS assurance and the implementing method thereof, it includes at least : a switching function unit, which supports the resource scheduling and isolation, and support to match the specific service with the specific network resource and forward the specific service using the specific network resource; and resource control function unit, which controls and manages the resource scheduling of switching function unit, and downward-transfer the resource scheduling and the allocation rule as well as the mapping relation of the resource and the service to switching function unit. The logic networks loaded service by the bearer system are separated each other, QoS of various services is not affected from other services, and it can receive QoS feedback of the service network, schedule the resource in the IP bearer system, and improve the QoS assurance for services.

The invention provides a construction method of a high-speed railway asphalt graded broken stone foundation bed. The construction method comprises the following steps of construction preparation, spreading of permeable asphalt and/or adhesive asphalt, mixing of asphalt graded broken stone, transportation of the asphalt graded broken stone, paving of the asphalt graded broken stone, compaction of the asphalt graded broken stone and maintenance of the asphalt graded broken stone. The invention also provides the high-speed railway asphalt graded broken stone foundation bed prepared by the method.The asphalt graded broken stone foundation bed prepared through the construction method serves as a new high-speed railway subgrade structure form, subgrade filler can be saved, the subgrade bearingcapacity and the waterproof and drainage capacity are improved, the subgrade service life is prolonged, and the asphalt graded broken stone foundation bed has wide application prospects and remarkableeconomic and social benefits.

The present invention relates to a method, device and system for reducing a call drop rate in the field of the audio business field in the long-term evolution system. The method comprises: receiving a UE context releasing request sent or ERAB releasing indication information by an eUB, when the UE context releasing request sent or ERAB releasing indication information carries special identification, remaining the BGR bearing, and the special identification is used for indicating to remain the GBR bearing. Correspondingly, the present invention further discloses a method, device and system for reducing a call drop rate. The method, device and system for reducing the call drop rate can effectively reduce the call drop rate of the UE in the VoLTE business and improve the user experience.

The invention belongs to the field of frame wharfs, and particularly relates to a flexible connecting structure of an overhead vertical frame wharf and an overhead ramp wharf, which comprises a simple support plate, a bottom beam, a polyurea cushion layer, frame columns, a deflector rod, a rotating shaft B, a universal joint and a telescopic rod, a groove with an inverted trapezoidal cross section is formed in the top of the bottom beam; when a moderate earthquake or an intensity earthquake occurs, relatively large relative displacement is generated between the overhead vertical frame wharf and the overhead slope ramp wharf, and the simple support plate moves upwards along the inclined plane C or the inclined plane D of the bottom beam groove under the action of tension or pressure at the two ends; rigid connection between the overhead vertical type frame wharf and the overhead slope ramp wharf is automatically relieved, structural safety is guaranteed, and the purposes that in the three-level targets of earthquake fortification, middle earthquakes can be repaired, and large earthquakes do not fall down are achieved.

The invention discloses an inspection door opening and closing mechanism. The inspection door opening and closing mechanism comprises a cross beam, a rotating assembly, a hoisting arm, a hoisting assembly and an inspection door; and the rotating assembly is arranged on the cross beam, the hoisting arm is L-shaped, the upper end of the hoisting arm is a vertical part, the lower end of the hoistingarm is a horizontal part, the upper end of the hoisting arm is rotatably matched with the rotating assembly, the hoisting assembly is arranged at the lower end of the hoisting arm, and the inspectiondoor is matched with the hoisting assembly. According to the scheme, a fixed hoisting rotary structure is adopted, bearing of the weight of the inspection door is guaranteed through the bearing crossbeam and the rotating assembly, and meanwhile the rotating flexibility after bearing can be guaranteed; a sliding type pin shaft structure can be adopted at the joint of the inspection door opening and closing mechanism and the inspection door, displacement is carried out along with opening of the inspection door, and the function of pulling out the inspection door while rotating is achieved; andworkload and time for opening and closing are greatly reduced, and frequent observation and maintenance on site are facilitated.
