The invention discloses an adjacent well detection method based on the theory of interaction between wellbore and elastic wave. It includes the following steps: firstly, the orthogonal dipole sound source and receiver pointing to x and y in the instrument coordinate system x-y are placed in the exploratory well, and the excitation x and y points to the sound source to radiate elastic waves to the formation outside the well; and y-directed receivers respectively collect four-component signals (xx, xy, yx, yy); taking the angle φ relative to the instrument’s x-axis or a fixed direction as a variable, the four-component out-of-well signals are used to form a synthesis of φ-directed transmission and reception Signal XX, change the value of φ to get the angle φ when XX reaches the maximum amplitude 0 ; If the measured external signal is elastic longitudinal wave, φ 0 is the azimuth of the target well; if the signal is an elastic shear wave whose polarization direction is perpendicular to the well, then φ 0 +90° is the azimuth of the target well; for the maximum amplitude signal XX(φ 0 ) imaging to determine the distance between the target well and the exploratory well. The invention can obtain the distance and orientation information of adjacent wells near the drilling well, and provide important data for well cluster anti-collision and safe production in oilfield exploitation.

The invention relates to the technical field of information and discloses a data collection method and system for a product production line, and a server. The method comprises the steps of obtaining identifiers of a plurality of products on a production line; associating the identifier of each of the products with production line basic information corresponding to each product; and when the identifier of at least one of the products is not obtained, associating the non-obtained identifier of the at least one product with the production line basic information corresponding to the at least one product according to the obtained identifiers of the products and the production line basic information corresponding to the products. According to the method, the system and the server, the identifiers of the products on the production line can be effectively collected; for the products of which the identifiers are not obtained, the products do not need to be separated from the production line and the identifiers are accurately obtained through the products of which the identifiers are obtained; and data collection of all the products of the production line is realized, so that a large amount of time, manpower and equipment costs are reduced and the data collection efficiency of the production line is greatly improved.

The invention relates to an experimental platform for dynamically simulating groundwater. The experimental platform comprises a dynamic simulation device, an aeration device, a simulated rainfall device and a center controlled computer. The experimental platform disclosed by the invention forms a typical underground hydrogeological unit model, by on-line monitoring the dynamic simulation device, a process that a pollutant enters into a ground aquifer from an earth surface can be simulated, and the process that the pollutant in the groundwater aquifer migrates and transforms from a recharge area and a runoff area to a discharge area can be simulated, so that the simulation and reappearing of a hydro-dynamical field and a hydrochemistry field can be all-dimensionally realized, the transportation process of a drug in aeration zone soil and in the aquifer can be clearly observed, and deeply analyzing the solute transportation, the migration and the transformation rule of the drug in the aeration zone soil and in the aquifer is convenient. According to the invention, the component, the structure and the operating principle of an original physical simulation device are changed, and an organic combination of the aeration zone and the saturated zone is realized, so that the experimental platform not only can meet the requirement of an unsaturated seepage simulation in the aeration zone soil, but also has a two dimensional or multi-dimensional flow simulation capability, and can enable a 'real' field hydrogeological condition to be reappeared in a laboratory.

The invention discloses a mobile vehicle-based data acquisition method in a smart city edge network. The method comprises: enabling sensor nodes to acquire hop counts of vehicles; evaluating the transmission overhead from the alternative cluster heads to the vehicle according to the transmission distance to the vehicle and the residual energy, and selecting the alternative cluster head with the minimum overhead as a cluster head node; according to the transmission distance from each candidate father node to the vehicle and the minimum node energy in the path, evaluating the transmission overhead from the source node to the vehicle through each candidate father node, and selecting the candidate father node with the minimum overhead as the father node of the candidate father node; for the source node with the hop count of 1 and the non-cluster head, taking the cluster head node as a father node; and enabling each sensor node to send the cached data and the received data to the father node, and finally sending the cached data and the received data to the vehicle through the cluster head. According to the method, the cluster head and the father node are selected by considering the transmission distance and the residual energy factor, so that an energy cavity phenomenon caused by premature death can be avoided, and data acquisition is effectively completed.
