The present invention discloses a method for selecting a real-time service data transmission path, comprising establishing an independent bearer control layer comprising more than one bearer network resource manager between a service control layer and a bearer network. The method further comprises: after a source bearer network resource manager which is connected to the service control layer receives a connection request for a real-time service, orderly selecting and determining, from the source bearer network resource manager towards a destination bearer network resource manager, an intra-domain route path for the real-time service in a management domain corresponding to each bearer network resource manager, and an inter-domain route path between adjacent management domains corresponding to adjacent bearer network resource managers. In addition, the present invention discloses six methods for selecting a real-time service data transmission path based on different strategies. The methods according to the present invention can increase success ratio of routing, and can obtain an optimal route in simple and flexible manners, thus can guarantee reasonable allocation of resources.

An Air food-passing robot comprises two transmission wheels arranged in a transmission track. One end of each transmission wheel is connected with a servo motor, and the other end is connected with a connecting rod through a servo motor rotation shaft. The connecting rods are in circuit connection with a microcontroller. A stepping motor rotation shaft is connected with a food-passing container through a lifting line. The food-passing method comprises the steps of: 1) a service plate containing food is put into the food-passing container, a table number is input, a digital tube displays the table number, and a liquid crystal displays the food name; 2) the microcontroller controls a stepping motor to work, and the stepping motor lifts the food-passing container; 3) the microcontroller controls the servo motors to work so as to drive the two wheels to move towards a target dining table; 4) after a magnetic field, a reed relay is closed, and when the value of a counter is equal to the table number, the two wheels arrives the part above the target dining table; 5) the stepping motor rotation shaft drives the food-passing container to decrease, and a food taking port is closed of the food is taken out; and 6) the food-passing container rises to the original height again, and servo motors return to the original positions. The food-passing robot is safe, highly-efficient, convenient to operate and intelligent.

The invention discloses a method for processing a main cable saddle of a suspension bridge. A side span (1) and a midspan (2) of the main cable saddle are respectively processed, then a bolt (3) is used to connect the side span and the midspan, and a joint surface of the side span (1) and the midspan (2) is provided with a positioning pin hole (6). The method guarantees the consistency of the size of a rope groove after the side span (1) and the midspan (2) are butted, has no alternate edges, high butting accuracy and small error, unifies processing reference, has low requirement on processing equipment, is more convenient for clamping and calibration of workpieces, is easy to guarantee processing accuracy, and improves processing efficiency.

The present invention discloses an e-commerce platform commodity transaction collective quotation management system. The system comprises a buyer's bid unit, a seller's quotation unit, a pricing unit, a matching unit, a data analysis unit and a payment unit; the buyer's bid unit is used for acquiring the quantity of commodities and corresponding bid information which are sent by a buyer through a client server; the seller's quotation unit is used for acquiring the quantity of commodities and corresponding quotation information which are sent by a seller through a manufacturer' server; the pricing unit calculates the priced prices of the commodities according to received valid buyer's bid and seller's quotation information and adopts the priced prices of the commodities as references for next price acquisition; the matching unit is used for performing matching to confirm the conclusion of a transaction according to the received valid buyer's bid and seller's quotation information; the data analysis unit confirms a transaction platform system and detects whether the quantity of the commodities satisfies specifications, whether a transfer unit price and a minimum price are within a specified range, whether a deposit bank is matched with a receiving account; and the payment unit is used for informing the buyer of a transaction price and then providing third-party payment platform services for the buyer, so that the transaction can be completed. With the system of the invention adopted, exchange efficiency is higher, and resource allocation is more reasonable.

The invention proposes a low-delay high-reliability resource allocation method based on deep reinforcement learning, and NR-V2X side chain resource allocation outside the coverage range of a base station is considered, wherein a vehicle schedules URLLC slice resources used by V2V users in a 5G network according to information observed by the vehicle and a Q network obtained in a training stage. In order to maximize the energy efficiency of V2V communication and ensure the reliability and time delay requirements of communication, a deep reinforcement learning architecture using centralized training and distributed execution is provided, and a model meeting the requirements is trained by means of a DDQN learning method. Modeling of targets and constraints in a resource allocation problem is converted into income design in deep reinforcement learning, the joint optimization problem of V2V user channel allocation and power selection can be effectively solved, and the performance is stable in optimization of a series of continuous action spaces.

A hydraulic fast forging unit adopting superposed oil supply of hydraulic pumps and high-pressure accumulators comprises a forging and pressing hammer, a main hydraulic cylinder, single-rod return stroke hydraulic cylinders, the main hydraulic pumps, the high-pressure accumulators, a medium-pressure accumulator, an oil tank and a valve control system. During the return stroke of the forging and pressing hammer, hydraulic oil in the single-rod return stroke hydraulic cylinders is supplied by the main hydraulic pumps, and stored oil in the main hydraulic cylinder is drained into the medium-pressure accumulator; during the idle-stroke fast dropping of the forging and pressing hammer, hydraulic oil in the main hydraulic cylinder is supplied by the medium-pressure accumulator independently, stored oil in the single-rod return stroke hydraulic cylinders is drained into the oil tank, and the main hydraulic pumps supply oil to the high-pressure accumulators; during rolling of the forging and pressing hammer, hydraulic oil in the main hydraulic cylinder is supplied by the main hydraulic pumps and the high-pressure accumulators in a superposed supply manner; during execution of the fast forging manner, hydraulic oil in the main hydraulic cylinder is supplied by the main hydraulic pumps and part of the high-pressure accumulators in a superposed supply manner, and during the fast return stroke, hydraulic oil of the single-rod hydraulic cylinder is supplied by the other part of the high-pressure accumulators; and control hydraulic oil of the valve control system is supplied by the high-pressure accumulators.
