The invention is an optical spectrum quantitative automatic analysis method, firstly determining an optical spectrum quantitative automatic analysis method of the four quantifying methods: non-normalization wavelength quantifying, normalization wavelength quantifying, area quantifying and speed quantifying and the quantitative parameters, then in the automatically ergodic circulating course, calculating light measurement the current values of the quantitative parameters, making linear fitting on the light measurement and measured quantity by using least squares method, recording all the quantitative parameters and corresponding related coefficients and finding the maximum related coefficient, and after the automatic ergodic course is finished, obtaining a 'related coefficient-quantitative parameter relation chart' and the suggested optimum quantitative parameter. It provides an automatic analysis method for the quantitative analysis result of optical spectrum, can evaluate quantitative measuring ability of the instrument for the special sample on given condition, gives the optimum quantitative analysis parameter and range and provides the reference for the users of spectral photometer and spectrograph.

The invention relates to a water seepage test device for building exterior walls for building supervision, comprising a detection frame and a water supply device installed on the detection frame. The detection frame includes installation rods, and a spray pipe is installed between the two installation rods. There are spray holes on the side near the wall.

The invention discloses a bridge life cycle management system based on big data processing, which belongs to the technical field of bridge management. The invention uses the setting of a seepage detection device so that when water seeps into the wooden bridge deck due to damage to the bridge deck, the sense seepage The expansion agent can spontaneously expand and trigger the signal sending button, so that the relevant staff can detect the damage of the bridge deck in time, and the image acquisition device combined with the processing and analysis system can complete the analysis and judgment of the type of bridge deck damage. In the prior art, manual regular detection, the present invention is not only efficient and timely, but also can analyze and judge whether the type of bridge deck damage is cracking on the surface of the bridge deck. If it is cracking on the surface of the bridge deck, the crack can be directly repaired and maintained. On the contrary, the staff can check the waterproof layer when the waterproof layer is known to be damaged, so that it is not easy to miss, which greatly improves the practicability.

The invention discloses a DSM automatic comparison system based on aerial photography measurement, which belongs to the technical field of aerial photography measurement. The elevation data of the two-phase aerial photos processed by the image processing module is extracted, the elevation conversion module is used to convert the elevation data of the two-phase aerial photos extracted by the elevation extraction module into a vector layer, and the layer overlay module is used for the two-phase aerial photos The vector layer of the photo is superimposed, and the comparison and labeling module is used to mark the area that has changed in the vector layer of the two-phase aerial photo. The time and manpower input for the comparison can more accurately detect the existence of illegal buildings. The comparison is more pertinent, and the effect of buildings with different areas can be screened by adjusting the value of each value.

The invention discloses a phytoplankton sorting and filtering device, which aims to solve the problem of inconvenient removal of impurities mixed in phytoplankton. The invention includes a frame, a rotating drum, and a sorting guide plate. The rotating drum is arranged horizontally. The sorting guide plate is placed under the rotating drum. There is a gap between the rotating drum and the sorting guide plate. There are several shearing grooves at intervals, and several rings of shearing knives are installed on the drum corresponding to the shearing grooves. One end of the shearing knife can be inserted into the shearing groove, and the other end is hinged on the drum. A cleaning mechanism is installed between the cylinders; a receiving trough is placed under the shearing trough; a filter trough is placed near the end of the sorting guide plate, and an inclined filter plate is installed on the upper part of the filter trough. The higher end of the plate is equipped with a cleaning pipe. The phytoplankton sorting and filtering device can automatically remove impurities mixed in the phytoplankton, and at the same time, cut the phytoplankton.

The invention discloses an intelligent harvester for a dwarf and close-planting fruit-bearing forest, and belongs to the technical field of agricultural machine.The intelligent harvester comprises a supporting assembly, a suction assembly and a separation assembly, the supporting assembly is located on the outermost side of the whole device, the suction assembly is arranged in the supporting assembly, and the separation assembly is arranged in the middle of the supporting assembly. The device is simple in structure and safe and convenient to use, the device sucks and collects jujubes knocked down on the ground by an external vibration falling device through negative pressure suction, omission is not prone to occurring, the device can filter and isolate impurities such as leaves, the harvested jujubes are not doped with the impurities, the device can obtain a transient non-suction state, the leaves can fall off conveniently, and the device is convenient to use. According to the device, the filter screen is arranged, leaves cannot block the filter screen, large and small jujubes are intermittently separated through the supporting strips, the jujubes and the small jujubes are separately stored, meanwhile, the phenomenon that the jujubes are stacked on the cambered-surface supporting plate is avoided through intermittent separation and storage operation, and the jujube separation effect cannot be affected by jujube stacking of the device.
