The invention discloses a quality monitoring method, device and system based on electronic product learning. The method includes the steps of when a user uses an electronic product to watch a teaching file, obtaining the brain wave information and eye activity information of the user, conducting a confluence analysis on the brain wave information and the eye activity information to determine the user's real-time learning state; marking the real-time learning state on a corresponding playing position in the teaching file. In this way, by conducting the confluence analysis on the user's brain wave information and the information of the eye activities to determine that the user's real-time learning state is marked on the corresponding playing position in the teaching file, the learning state of the user can be monitored and marked, more convenience is provided for user's reviewing and learning in the later period, and the user's learning quality is improved.

The invention discloses a TD-LTE (Time Division Long Term Evolution) network quality monitoring system, comprising an operation maintenance center and a monitoring terminal. The operation maintenance center and the monitoring terminal are in signal connection through a TD-LTE mobile communication network. The system performs the following steps that the operation maintenance center issues a test task to a fixed monitoring terminal through the mobile communication network or a mobile monitoring terminal automatically obtains the test task; the monitoring terminal monitors current network signal quality according to the test task and reports monitored network signal quality parameters and test results to the operation maintenance center through the TD-LTE mobile communication network; and the operation maintenance center carries out statistics and trend analysis, thereby evaluating the network signal quality of a location where the monitoring terminal is at.

The invention discloses a water sample collector, and relates to the technical field of environmental water quality monitoring, and aims to solve the problem of energy wasting. The water sample collector is characterized by comprising a floating frame, a collecting tank and a connecting rope, the collecting tank is of a structure only with an opening in the upper end face, and an opening-closing structure is arranged at the opening in the upper end of the collecting tank; the opening and closing structure comprises a cover body fixed at the opening end of the collecting tank, the cover body is provided with an opening, the cover body is hinged with a turning cover which is embedded to seal the opening, a traction rope is arranged between the movable end of the upper surface of the turning cover and the floating frame, and the length of the traction rope is smaller than the releasing length of the connecting rope. According to the water sample collector disclosed by the invention, the energy consumption is effectively reduced, and the hidden danger of flow exchange between a water sample and upper-layer liquid is eliminated.

The invention discloses a multipoint electric energy quality monitoring system for a transformer substation. Based on a plurality of electric energy quality parameter acquisition nodes and transformerstation working condition acquisition nodes, electric energy quality parameters and transformer station working condition parameters are autonomously acquired. the electric energy quality parametersand the transformer substation working condition parameters are uploaded, processed and identified through the monitoring terminal to obtain an electric energy quality event identification result anda transformer substation working condition evaluation result; and a corresponding maintenance strategy is obtained and output according to the power quality event identification result and the transformer substation working condition evaluation result. The curve graph is generated according to the preset drawing rule, and the display screen is controlled to display the curve graph, so that visualexpression and accurate classification and identification of the power quality events are realized, evaluation of the working condition of the transformer substation is realized, a maintenance strategy can be automatically provided, and stable operation of the transformer substation and power quality of the transformer substation are guaranteed.

The invention discloses an urban-rural sharing model of agricultural resources based on network big data and a use method thereof. The model comprises: a city resident information storage module, which establishes a consumption unit and collects and stores the information of the residents in the unit to generate demand data; a farmer household information storage module, which establishes a supplyunit, collects and stores the farmer household information in the unit to generate supply data; a selection module, wherein the consumption unit and the supply unit select each other or match the demand data and the supply data to generate the supply chain information; a quality monitoring module that performs quality inspection on the vegetables supplied by the supply unit and judges whether thevegetables supplied by the supply unit are qualified or unqualified; a settlement unit that performs bi-directional settlement based on the quality inspection result and the case where the supply unit receives the supplied vegetables. The invention not only avoids the economic loss of the peasant households by establishing a supply chain between the urban residents and the peasant households, butalso enables the urban residents to eat the assured green vegetables by detecting whether the vegetables are qualified or not.
