The invention relates to a display device, a display system and a resolution adjustment method. The display device comprises a display screen, a distance sensor and an adjustment unit, wherein the distance sensor comprises a particle emitter for emitting a first particle beam to an observer and a particle receiver for receiving the first particle beam reflected by the observer; and according to the energy density of the emitted first particle beam and the energy density of the received first particle beam, the adjustment unit adjusts the resolution of the display screen. According to the technical scheme of the invention, the resolution of the display screen can be adjusted according to the observation distance between the observer and the display screen, and when the user observation distance is large, the resolution of the display screen can be reduced properly, and the power consumption amount of the display screen is reduced on the premise of ensuring user observation effects.

The invention discloses an automatic paper-cup ice cream filling machine belonging to food filling machinery. The automatic paper-cup ice cream filling machine comprises a rack, a power mechanism, a filling mechanism and a caterpillar mechanism, wherein the rack consists of a cross beam support, a first cross beam, a second cross beam and a group of cross beam supports; the power mechanism is arranged at one end of the rack; the filling mechanism is arranged at the other end of the rack; the caterpillar mechanism is arranged between the first cross beam and the second cross beam; a first horizontal folding edge is formed at the upper part of the first cross beam, a first vertical folding edge is formed on the first horizontal flange, a second horizontal folding edge is formed at the lower part of the first cross beam, a third horizontal folding edge is formed at the upper part of the second cross beam, a second vertical folding edge is formed on the third horizontal folding edge, and a fourth horizontal folding edge is formed at the lower part of the second cross beam; fixed flange seats are respectively fixed at the two ends of the group of cross beam supports; and the power mechanism comprises a motor, a reduction gearbox, a main transmission wheel, a cam, a pawl, a large sprocket shaft, a ratchet wheel disc, a first large sprocket, a second large sprocket and an inertia elimination device. The intensity of the cross beams is ensured, the safety is ensured, and the reliability of movement and pause of paper cups carried by the caterpillar mechanism is ensured.

The invention provides a secondary video data coding method. The method comprises following steps of: coding acquired video data in a first preset way so as to acquire first image data; coding the acquired image data in the YUV format in a second preset way so as to acquire second image data; and carrying out network transmission on the second image data. According to the invention, it is achieved that video resolution is unchanged and transmission error rate is reduced; video viewing effects are ensured; transmission cost is quite low; and high-quality requirements required for the monitoring are met.
