The utility model relates to the technical field of greenhouses, in particular to a greenhouse film feeding device for a greenhouse. The device is arranged on the two sides of a greenhouse frame and comprises a film line pay-off frame, a film line take-up frame and a greenhouse film tensioning assembly, a greenhouse film line is arranged on the film line pay-off frame, the film line take-up frame is arranged at the position, corresponding to the film line pay-off frame, of the other side of the greenhouse frame, and the greenhouse film line is connected with the film line take-up frame after being wound around an arch frame of the greenhouse frame. The greenhouse film tensioning assembly is connected with the greenhouse film line, and the greenhouse film tensioning assembly is connected with a greenhouse film. The device is good in winding displacement accuracy and high in film feeding efficiency, an operator does not need to climb to a greenhouse frame, the construction safety is improved, the construction speed is increased, and the greenhouse construction efficiency is guaranteed. The utility model is mainly applied to the field of greenhouse film covering.

The invention relates to the technical field of bridge construction, in particular to a construction hanging basket operation risk real-time monitoring method and system. The method comprises the following steps: S1, deploying a monitoring system including sensing, transmission, data processing and early-warning brake layers; s2, early warning and braking threshold values are set; s3, the sensing layer collects parameters in real time in the walking process and transmits the parameters to the data processing layer through the transmission layer; s4, the processing layer preprocesses the data, calculates a displacement difference and a speed difference, and judges a balance state in combination with attitude parameters; and S5, executing continuous monitoring, primary early warning or secondary early warning and emergency braking according to a judgment result. In the system, a sensing layer comprises a high-precision laser displacement sensor, a tilt angle sensor and a stress monitoring module, a transmission layer adopts a'wired + wireless' mixed mode (delay is less than or equal to 0.5 s), a data processing layer comprises an edge computing terminal and a background monitoring center, and an early warning braking layer realizes graded prevention and control. According to the invention, automatic high-precision monitoring is realized, manual dependence is avoided, accurate early warning and braking are realized, overturning accidents are avoided, and construction safety and quality are improved.
