The invention discloses a smart home energy management optimization method in an Internet of Things environment. According to the method, the Internet of Things technology is utilized, intelligent identification and classified management are carried out on equipment, multiple energy management strategies are preset, and a user can conveniently and autonomously adjust; energy data is monitored in real time through a sensor and an intelligent electric meter, an energy consumption rule is mined by using a big data analysis technology, and a demand trend is predicted; constructing an intelligent energy dispatching center, and formulating a dynamic energy distribution scheme by using an optimization algorithm; a mobile phone application and an intelligent control panel are developed, and a user is supported to check data, control equipment and carry out personalized customization; and meanwhile, equipment firmware upgrading and remote management are realized. According to the invention, energy consumption can be reduced, cost can be controlled, equipment collaboration and energy distribution efficiency can be improved, user experience can be enhanced, system maintenance and upgrading are facilitated, and intelligent household energy management is more efficient, intelligent and flexible so as to adapt to diversified household requirements.

The invention discloses an intelligent advertisement design system based on big data, which relates to the technical field of data analysis, and comprises an acquisition module, a processing module, an analysis module and a design module, and is characterized in that associated materials are matched, a material group is obtained, the first duration of a first video is counted, a first ratio is calculated, a scoring model is constructed, a second duration is set, and a first operation is executed. And screening the key frame, setting a timestamp, setting a picture parameter and a sound parameter, and generating an advertisement fragment. According to the automatic advertisement design process, manual operation is reduced, time and resources are saved, related materials are matched according to product names, the attraction of advertisements is improved, the rhythm and duration of the advertisements are optimized, the watching experience of audiences is improved, a scoring model is constructed, advertisement design is more scientific and objective, key frames are intelligently screened, and the advertisement design efficiency is improved. And the picture parameters and the sound parameters are set according to the timestamps, so that different playing environments and audience requirements are met.

A road construction concrete pouring device includes a traction trolley, the traction trolley is equipped with a concrete pump, the traction trolley is provided with a pouring system, the pouring system includes a connecting mechanism, a pouring pipeline mechanism, a guide rail mechanism and a reciprocating drive mechanism, the connecting mechanism includes a rotating shaft, the pouring pipeline mechanism includes an outer sleeve and a telescopic tube, the outer sleeve is fixed to the rotating shaft, the telescopic tube is processed with a pouring tube, the guide rail mechanism includes a first longitudinal guide rail, the traction trolley is connected to the first longitudinal guide rail through a bracket, and the reciprocating drive mechanism is installed between the traction trolley and the bracket; by utilizing the technical solution of the invention, the concrete can be automatically swung during the concrete pouring process to achieve a large range of pouring, and the poured concrete is reciprocated along the width direction of the roadbed with uniformity, which reduces the time of manual paving work in the later stage and saves construction period.

The utility model relates to water protecting cylinder pile mounting equipment technical field, especially water full protecting cylinder cast-in-place pile guiding and positioning pile sinking system. Its technical scheme includes steel protecting cylinder and many auxiliary piles, still includes the guide frame in the auxiliary pile top, the top of auxiliary pile all movably sets up the steel hoop assembly of supporting guide frame, total station, places on the one end upper surface of guide frame, opens a plurality of positioning holes on guide frame. The utility model discloses the cooperation of auxiliary pile, steel hoop assembly, guide frame, total station and other structures, uses water full protecting cylinder cast-in-place pile guiding and positioning pile sinking system, through steel hoop assembly and forms the operation surface by fixing guide frame on auxiliary pile, total station positioning, vibration hammer pile sinking. Without setting up steel platform, solve the problem that the sporadic pile construction cost is high, and the construction period is long, also break through the space limit, guarantee the construction development, be favorable to construction deployment, construction period and scheme comparison and selection.
