Method for real-time direction finding of base station antenna ultrashort baseline GNSS double antenna
InactiveCN109613585AEliminate errorsGuaranteed reliabilitySatellite radio beaconingDouble differenceAmbiguity
The invention discloses a method for real-time direction finding of a base station antenna ultrashort baseline GNSS double antenna. The two-dimensional pose of a carrier can be determined by measuringa vector fixed on the carrier. The vector that reflects the two-dimensional pose of the carrier can be formed when the antennas of two receivers are mounted on a rigid carrier. And the heading angleof the carrier can be calculated by accurately determining the direction and distance of the two ends of the vector in space. According to the method for the real-time direction finding of the base station antenna ultrashort baseline GNSS double antenna, the common errors of the satellite and the receiver are eliminated by constructing a double difference model to perform a global solution on thebaseline vector. The problem of the frequent replacement of a reference star is avoided by firstly solving the single-difference ambiguity between fixed stations. The reliability of the baseline vector is ensured by using the EKF solution. The single epoch can be guaranteed to be solved, the real-time performance is effectively ensured, and in particular, various errors in the observation of the low-cost positioning module and the antenna in the absolute positioning are prevented from affecting the receiver antenna and making the high-precision position difficult to obtain.

Magnetic fixed medical sharps box and using method thereof
InactiveCN109533730ASave spaceAvoid frequent replacementSurgical furnitureRefuse receptaclesMagnetic tension forceMotor drive
The invention discloses a magnetic fixed medical sharps box and a using method thereof. The magnetic fixed medical sharps box comprises a collection box, a shearing mechanism and a control system, wherein an electromagnet group is arranged at the inner bottom of the collection box; the shearing mechanism comprises a rotating shaft, a cutter blade, a cutter head and a rotor motor; the cutter bladeand the cutter head are arranged on an opening of the top of the collection box; the rotor motor and the cutter blade are arranged on the rotating shaft; a metal plate is arranged on a cover of the collection box; a top electromagnet is arranged at the corresponding position of the top of the box; when a start button on the control system is pressed down, the electromagnet group is charged, a stepper motor drives a push rod to open the cover of the collection box, sharps are put in the box, a cutting-off button on the control system is pressed down, the rotor motor drives the cutter blade to cut off a flexible pipe, and the sharps are tightly absorbed at the bottom of the box under the action of the magnetic force of the electromagnet group. When the collection box is almost full of the sharps, the box cover can also be automatically locked and is prevented from falling out. The magnetic fixed medical sharps box avoids the accidental injury caused by the direct contact between medicalpersonnel and discarded sharps, and is convenient and safe to operate.

Large-caliber reflection mirror iterative precompensation grinding method based on grinding wheel wear prediction
ActiveCN107378687AExtended service lifeHigh precisionOptical surface grinding machinesTarget surfaceNumerical control
The invention relates to a large-caliber reflection mirror iterative precompensation grinding method, in particular to a large-caliber reflection mirror iterative precompensation grinding method based on grinding wheel wear prediction. In order to solve the problems that in the prior art, under the fixed nominal grinding depth, the target surface figure accuracy is achieved through repeated replacement of a grinding wheel for repeated grinding, consequently, the grinding wheel losses are serious, the surface figure accuracy is poor, and wear efficiency is low, the method comprises the steps of building a predication model of the grinding wheel grinding ratio G about the grinding parameter, secondly, building a radial size wear amount predication model at the grinding wheel wear point in the grinding process, thirdly, building a non-spherical-face surface-shape error predication model, fourthly, through the iterative precompensation method, calculating wear surface-shaped error values of all points on a non-spherical-face generatrix until the requirements are met and fifthly, recording nominal grinding depth final predication values of all contact points in the iterative process, and carrying out numerical control grinding machining programming and subsequent machining. The method is used for the technical field of grinding machining of an optical non-spherical-face reflection mirror.
