ActiveCN104793225ARealize the positioning functionSolve the problem of temporarily unable to locateSatellite radio beaconingVIT signalsElectronic map
The invention discloses a satellite navigation positioning method based on doppler velocity measurement under a transient and incomplete condition. The satellite navigation positioning method comprises the steps that normal positioning is conducted under the condition that satellite signals are complete, and related positioning information is stored; when the satellite signals are shielded, and the number of visible satellites is three, the satellite navigation positioning method under the incomplete condition is executed, an auxiliary equation is established according to the relation among doppler frequency offset, the receiver velocity and the satellite velocity, cutoff of first-order terms and linearization of a nonlinear system of equations are conducted through taylor expansion, and then the nonlinear system of equations is calculated through a least square method, so that the position and the velocity of a receiver are obtained; when the number of the visible satellites is recovered to be four or more, a positioning method under the complete condition is executed. The actual test result shows that the satellite navigation positioning method achieves the positioning result required by navigation in the transient and incomplete period of dozens of seconds, and therefore the effectiveness of the GNSS receiver is improved. The satellite navigation positioning method does not rely on additional sensors, does not require additional instruments and meters, does not require electronic map supporting, and is small in calculated amount and free of increase of the system cost.

Method for solving problem of solder resist photosensitive white oil pencil marks

InactiveCN109819599ANo need to increase wattageNo need to extend exposure timeNon-metallic protective coating applicationCooking & bakingScreen printing
The invention discloses a method for solving the problem of solder resist photosensitive white oil pencil marks. The method comprises the steps that a metal substrate is pretreated through sand blasting or volcanic ash; crude oil and printing ink are standardized by manufacturers: the viscosity is controlled to be 140-170 dga.s; the metal substrate is printed through a screen printing machine, andthe thickness of ink on the circuit surface is controlled to be 20-30 [mu]m; the metal substrate stands for 30 min at the corresponding position after being printed each time; the metal substrate ispre-baked for the first time at the temperature of 75 DEG C for 32 minutes; after the metal substrate is pre-baked for the first time, after the printing ink is cooled, pre-baking for the second timeis performed at the temperature of 80 DEG C for 13 minutes; and the exposure grade of a 21-grade exposure ruler is controlled to be 9-13. According to the invention, through the pre-baking mode afterprinting is optimized, the method solves the problem of high-reflectivity solder resist white oil pencil marks, and meanwhile, the ink hardness is improved, traces left on the surfaces of the processing inks are avoided, pencil marks cannot be generated in the subsequent processing process, the appearance requirements of users are met, the reflectivity of the ink is reserved, and the ink can be popularized and used in the industry.

Valve port device with sealing function for valve bag

InactiveCN112249497AMitigate leaksLow costBagsSacksPhysicsEngineering
The invention relates to a valve port device with a sealing function for a valve bag. More than one valve block is arranged in a valve barrel; one end of each valve block, which faces a feeding port of the valve barrel, is fixed on the inner wall of the valve barrel; and one end of each valve block, which faces a discharging port, is movably separated from the valve barrel. The valve port device provided by the invention is used on a paper, plastic or paper-plastic composite valve port bag and used for replacing an existing valve port, and the multiple valve blocks are arranged in the valve barrel, so that material leakage can be stopped multiple times and in multiple dimensions: materials in the bag are extruded in multiple directions from outside to inside to enable the valve barrel to be closed to achieve primary sealing, materials remaining in the valve barrel and materials extruded into the valve barrel can be intercepted by the secondary valve block to achieve secondary sealing,and a gap between the secondary valve block and the discharging port of the valve barrel is filled with the materials which can expand to further reduce a main channel of the valve port device to prevent the materials from leaking so as to achieve tertiary sealing. Due to the multi-layer and multi-dimensional sealing mode, material leakage is greatly relieved.

Excavator silting working condition detection system and detection method

The invention relates to an excavator, and provides a bogged-down condition detection system for the excavator to safely detect whether a bogged-down condition risk exists in a construction position of the excavator. When the excavator detects whether the bogged-down condition risk exists in the construction position, a bucket baseplate is flatly placed in the construction position to be detected,a boom cylinder is retracted to sink a bucket into the ground till the boom cylinder cannot be further retracted, a controller calculates an acting force onto the plane of the bucket baseplate from the ground and the sinking depth of the bucket according to a detected parameter value, the maximum ground pressure which can be borne by the construction position and the permitted sinking depth of the whole machine are compared in combination with area calculation of the plane of the bucket baseplate to judge whether the construction position can lead to a bogged-down condition of the whole machine, and a judgement result is displayed on a display. The bogged-down condition detection system can accurately judge whether the bogged-down condition of the whole machine can occur in the construction position or not under the condition of guaranteeing that the whole machine is away from a dangerous position, and a driver is reminded, so that the probability of an accident is effectively reduced.
