The invention discloses an automatic computer power supply switching test system and method. The automatic computer power supply switching method includes S1, setting transmission periods of starting and shutdown signals through main units at a control end and transmitting the starting and shutdown signals to a signal control unit according to the transmission periods; S2, receiving the starting and shutdown signals transmitted by the main units of the control end through the signal control unit, converting the starting and shutdown signals into control signals and transmitting the control signals to a 220V power supply switching control circuit; S3, outputting 220V alternating current to main units to be tested by the 220V power supply switching control unit according to the control signals. By presetting testing periods, the starting and shutdown signals can be manually transmitted in real time or automatically transmitted at fixed time to the signal control unit, and the signal control unit correspondingly controls the 220V power supply switching control circuit to start power supply intermittently for the main unit to be tested after receiving the starting and shutdown signals of the main units of the control end. Besides, the automatic computer power supply switching test system and method can realize one-to-many power on-and-off test of the main units to be tested on a large scale, and labor cost is greatly saved. Leisure time can be sufficiently utilized, test period is greatly shortened, long-time multi-times testing is realized, and stability of products is improved.

The invention relates to the technical field of automobiles, in particular to a vehicle upgrading method, system and device based on a charging pile The vehicle upgrading method based on a charging pile comprises the steps that when the charging pile charges a vehicle, a charging pile system judges whether the vehicle meets a preset upgrading condition or not, and if the vehicle meets the preset upgrading condition, a software version of the vehicle is collected; whether the software version of the vehicle is inconsistent with a target software version of an OTA platform or not is judged, and if not, the charging pile system obtains a software upgrade package from the OTA platform; the charging pile system upgrades the vehicle according to the software upgrade package; and the vehicle is in wired connection with the charging pile, and the OTA platform is in wired connection with the charging pile. According to the method, the charging pile is in wired connection with the vehicle and the OTA system, so that the upgrading process is more stable, it can be ensured that the vehicle is in an unused state, and the idle time during charging is fully utilized.

The invention belongs to the technical field of aquaculture, and particularly relates to a method for river crab pond breeding and procambarus clarkii annual breeding. The method comprises the steps that firstly, a one-meter-high purse seine is arranged at 50-60 cm below the water surface of a pond, and a larval breeding area is formed; secondly, parent shrimp are put at the end of August or at the early September, wherein the weight of one parent shrimp is 40 g, and the female-male ratio is 3:1; thirdly, the shrimp and the crabs are fed with feed from the late September, and culturing is strengthened at the water temperature of 10 DEG C or above; fourthly, the postpartum parent shrimp are caught starting from November; fifthly, commercial river crabs are caught starting from the early November to the early January of the next year; sixthly, the shrimp and the crabs are fed with expanded sinking pellet feed at the end of the middle of March of the next year; seventhly, the commercial shrimp of 30 g or above are caught from the late April of the next year to the late August of the next year; eighthly, river crab larvae of 18 g are put in the middle of May, and fed with the expanded sinking pellet feed, the feeding amount is increased to 5% from 1.5%; ninthly, the commercial shrimp of 40 g are reserved to serve as the breeding parent at the late August, and the next round of larval shrimp breeding is started at the end of August or at the early September; tenthly, the river crabs start to be caught from the late October.

The invention relates to a human-aided electric power and manual-power double-power coordination interaction body-building tricycle. The human-aided electric power and manual-power double-power coordination interaction body-building tricycle is designed into a right three-wheeled vehicle; a front wheel of the right three-wheeled vehicle is a rotating wheel; pedals are arranged on the left side and the right side of the front wheel; and the pedals are used for controlling the direction. A rider can do body-building exercises with both hands during riding and can transmit the force to the wheels to help an electric wheel to advance. A manual driving wheel is arranged on the left side of the right three-wheeled vehicle. The driving force depends on forward-backward motions of two handles; by means of a lever principle, a semicircular arc chain track and a semicircular arc chain are driven to move forwards and backwards in a repeated manner; and a flywheel (one-way wheel) does work in one way. The other end of a half axle is tightened together with a wheel so that the wheel and the half axle synchronously rotate and the wheel and the electric wheel mutually drive the vehicle to advance. During body-building or riding, the rider sits in a wheel seat above a main frame and the handles are shifted forwards and backwards and separated and closed in a right-and-left direction; both legs and both feet step forwards and are drawn back backwards and the body moves forwards and backwards with the seat; and the head, neck and upper body bend forwards and backwards to do reciprocating motion so as to achieve a good body-building purpose.

The invention discloses a segmented junk recovery method for a solid-state storage device. The method comprises the steps of adding a cache which difficultly loses data after power failure and is specially used for recovering service junk and migrating effective data, and temporarily storing the effective data needed to be migrated by utilizing the cache in effective data migration of junk recovery operation; when erasure operation is performed, in a way of setting a marker for marking a plane or a die in which a target block subjected to block erasure operation is located, feeding back junk recovery operation completion to an upper layer and continuing to make a response to a coming request, namely, not making a response to the request by the plane or the die, thereby avoiding a time delay of the response caused by the fact that a write request allocates idle pages of the plane or the die; and at gap time when read and write requests come, writing back the effective data migrated to the cache which difficultly loses the data after power failure to the solid-state storage device. According to the method, the time delays of read and write responses caused by junk recovery can be effectively shortened without influencing the junk recovery efficiency.
