The utility model relates to a simple support of tomato field cultivation, including support pole, install the protective sleeve of support pole outer end, install the butt joint cover of support pole one end and install the snap ring of butt joint cover outer end, the outer end fixed of support pole has the clamping bar, the protective sleeve is used for protecting the pole body bottom and is not easy to rot and corrode, the outside of snap ring is equipped with the connecting frame, is equipped with the link plate on the connecting frame, the link plate is used for helping pole body between interconnect. The utility model discloses through the protective sleeve of support pole bottom sleeve setting inserts ground, effectively blocks the direct contact of soil and moisture and support pole, isolates soil and moisture, reduces the erosion of microorganism to pole body, reduces the possibility of decay, prolongs the service life of support pole, secondly, the protective sleeve can provide additional support for support pole, prevents the loosening or inclination of support pole, ensures the firm of support, reduces the risk of plant damage, guarantees the stable cultivation growth of plant.

This utility model discloses a railing device, relating to the field of railing technology. The device includes a post, a crossbar, and a wooden wedge-shaped locking strip. The post has a rectangular groove on its side; the crossbar has an insertion part at its end, with a wedge-shaped groove at its top; the locking strip has a right-angled trapezoidal cross-section and achieves mechanical self-locking by inserting its inclined surface downwards into the wedge-shaped groove. When the locking strip is inserted, its inclined surface presses against the inner wall of the wedge-shaped groove, forcing the insertion part to expand inwards and press against the inner wall of the rectangular groove, forming a horizontal compressive force; simultaneously, the top of the locking strip presses against the upper edge of the rectangular groove, resisting vertical pull-out force. This device uses an all-wood structure, eliminating the risk of corrosion from metal nails and extending its service life; at the same time, the wedge-shaped self-locking structure provides strong resistance to pull-out and impact, preventing loosening, and is suitable for outdoor scenarios such as parks and boardwalks.

The utility model discloses a strawberry fruit and leaf isolation frame which comprises two vertical rods and two transverse rods connected with the two vertical rods, the whole strawberry fruit and leaf isolation frame is in a # shape, the distance between the two vertical rods is 20-30 cm, each vertical rod comprises an upper section, a middle section and a lower section which are connected, the length of each upper section is 10-20 cm, the length of each middle section is 25-35 cm, and each lower section is an insertion section used for being inserted into soil and is 15-20 cm in length. The two cross rods comprise an upper cross rod and a lower cross rod and are connected to the middle section of the vertical rod, the distance between the lower cross rod and the top end of the lower section of the vertical rod is 5-8 cm, and the distance between the upper cross rod and the lower cross rod is 10-15 cm; an insect sticking plate mounting position is arranged on the upper section of the vertical rod; one end of each tying rope is tied to the transverse rod, and the other end of each tying rope is used for tying strawberry bearing branches. The fruit tree supporting frame can support fruit bearing branches, enables ripe fruits to be kept dry, and avoids decay, deterioration and insect damage.

The invention discloses a micro light emitting diode dynamic control system, control method and control device based on a multi-core heterogeneous chip. A task management and light field analysis unit TMU writes an analyzed light field descriptor set into an on-chip shared memory and sends a doorbell signal to a neural mimicry computing cluster NPU; a neural mimicry computing cluster NPU receives the light field descriptor from a task management and light field analysis unit TMU, reads historical data from a distributed shared memory, writes a processing result into the distributed shared memory, and triggers a high-precision driving computing cluster HPU and a distributed pixel driving network DPS; the high-precision driving calculation cluster HPU receives the instruction and the data, reads accurate parameters from the distributed shared memory and issues a final driving micro instruction to the distributed pixel driving network DPS; and the distributed pixel driving network DPS is used for receiving microinstructions and local parameters from the high-precision driving calculation cluster HPU. And inherent contradictions among power consumption, bandwidth, service life and display quality are solved.

The application discloses a theaflavins carbon quantum dots preservative film with monitoring and antibacterial effects, and a preparation method and application thereof, relates to the field of novel functional nanomaterials, and comprises a polyvinyl alcohol nanofiber matrix, theaflavins-based carbon quantum dots, citric acid and graphite phase carbon nitride dispersed in the matrix; the theaflavins-based carbon quantum dots are in-situ embedded in the polyvinyl alcohol nanofiber through electrospinning and are cross-linked and fixed in the polyvinyl alcohol nanofiber through thermal esterification to form a three-dimensional cross-linked network structure. The prepared carbon quantum dots form a heterojunction with graphite phase carbon nitride through an electrostatic field domain, and the antibacterial efficiency is synergistically enhanced, the photo-thermal performance is significantly better than that of tea polyphenol carbon quantum dots, and active oxygen can be generated. The application of the preservative film in fruit preservation has the dual effects of fruit freshness indication based on fluorescence quenching and antibacterial preservation, and the fruit storage period can be prolonged by 100% at room temperature.
