The invention provides a GNSS multimode single-frequency RTK cycle slip detection method and apparatus. The method comprises the following steps: communicating with a GPS satellite, a GLONASS satellite, a Galileo satellite and a Beidou satellite and obtaining corresponding data; according to a formula, carrying out calculation so as to obtain a residual error vector of a station epoch secondary difference carrier wave observation value of each satellite; according to the residual error vector, calculating an RMS value, and if the RMS value is greater than or equal to a threshold EPS, determining that a satellite generates a cycle slip; according to a formula (2), calculating a standard residual error V<->; comparing |error V<->| with u<alpha/2>, and carrying out corresponding operation; and fusing the determined cycle slip with a cycle slip detected by use of a Doppler integration method. The invention brings forward a novel method for detecting a cycle slip by combining a multimode station epoch secondary difference method and a Doppler integration method. The multimode station epoch secondary difference method detecting the cycle slip based on a residual error domain only sets one station epoch relative clock error parameter, such that even if a single system has only one satellite, effective utilization and cycle slip detection can still be realized.

Piston-chamber hydro-gravity engine

A piston-chamber hydro-gravity engine capable of converting the stagnant volume of the liquid matter of sea, lake, pond or artificially made hydro container, to a moving volume of liquid matter that flows back upon itself and in meanwhile exploits this motion as a working agent to produce mechanical kinetic power, capable of being used for mechanical production of kinetic work for hydro-electricity generation, or to be used multi-purposely for other energy needs that demand mechanical kinetic force sufficient to solve energy production problems worldwide forever beneficial to the economy and, friendly to the environment, consisting of particular accessories of mechanisms embodied in a single system of mutual successive co-operation by exploiting gravity, that is the hydro-container (7),; capable of creating the means of exploiting the gravity-hydro-static tension of squashing compression exist within the volume of liquid matter of the sea, lake, pond or artificially made containers, the cylinder-chamber (15) and piston-chamber (1) these convert the stagnant gravity- hydro-static tension of force into a fluctuating homo-acting and counter-acting to gravity hydro-gravity-moving-force of action, that compels the piston-chamber (1) to reciprocate, the hermetically sealed vessel crank-cam-shaft chamber (8) operating as a participator in creating the means of the system piston-chamber hydro-gravity engine's function and meanwhile participating in the embodiment system that converts the reciprocating motion of piston-chamber (1), to a rotating motion capable of being used multi-purposely,; where for the piston-chamber hydro-gravity engine to function it is necessary for the hydro-gravity force of action of conduits (19) to be less than the hydro-gravity force of action of piston-chamber (1), the area where conduits (19) adjusted hermetically fixed at the trunk of the cylinder-chamber (15) to be under the B.D.C. of piston-chamber (1).

Redundant and high-reliability partitioning method for embedded Linux system

The invention discloses a redundant and high-reliability partitioning method for an embedded Linux system and belongs to the field of computer systems. The method specifically comprises the following steps: (1) analyzing the structure and file constitution of the Linux system; (2) additionally installing a system disc based on a single system disc; (3) partitioning the system disc into four partitions; (4) detecting a starting system of the system disc by virtue of a GRUB (GRand Unified Bootloader) guiding method; (5) carrying out a self-repairing function on a dual-standby system disc; (6) starting the Linux system; and (7) carrying out high-reliability management on the dual-standby system disc. The redundant and high-reliability partitioning method has the beneficial effects that by providing a reliable and reasonable deployment method for the embedded Linux system, the reliability of the system during the operation is substantially increased; the frequency of IO (input and output) access to the system disc during the operation of the system is substantially decreased; by reasonably partitioning files of the Linux system and storing the files into different partitions, the interaction among the files is reduced; by utilizing two redundant backup system discs, the reliability of the system is greatly improved.
