The invention provides a method for determining the total mass of a solid waste heap, which comprises the following steps: dividing the solid waste heap into n rectangular cylinders, measuring the storage volume of each solid waste cylinder; measuring the highest cylinder The layered bulk density, and according to the measurement results, use neural network fitting to solve the bulk density of the nonlinear distribution of each layer, so as to calculate the average bulk density of each solid waste column; by measuring the heap density of each solid waste column The storage volume and the bulk density of the solid waste column are calculated to obtain the total mass of the solid waste to be identified. By adopting the technical scheme of the invention, the total mass of the solid waste pile can be measured simply, accurately and reliably, and fundamentally solve the long-standing problem that there is no positive direct measurement method for the total mass of the solid waste pile.

The invention relates to an anti-electromagnetic radiation textile simulating and testing instrument which is used for simulating and testing textile material. The technical proposal is as follows: a structure comprises a vector network analyzer and a flange coaxial device. The flange coaxial device is connected with an insertion loss or return loss test loop of the vector network analyzer. The middle part of the flange coaxial device is provided with a sample frame. The outer edge of the sample frame is provided with winding gaps with uniform intervals, wherein, the spaces of the winding gaps at the edge are same. The center of the sample frame is provided with a circular hole which is coaxial with a cavity in the flange coaxial device. Electromagnetic wires forming textile to be tested are wound at the winding gaps. The anti-electromagnetic radiation a textile simulating and testing instrument can simulate and test the textile with the electromagnetic wire array of different densities and provides reliable and exact data basis for designing anti-electromagnetic radiation textile satisfying the requirement further, and the anti-electromagnetic radiation textile simulating and testing instrument has simple structure and can test soft and hard plane material exactly.

The invention provides a position-based wireless checking system and a position-based wireless checking method. The checking system comprises a checking database, a checking data service module and a checking mobile client, wherein the checking database is used for storing checking commodity data and checking tabulate data; the checking data comprises commodity codes, checking quantity and commodity position codes; each commodity position code consists of a commodity storage body code, a storage body row code and a storage sequence number code; the checking data service module is used for providing summarizing, storage and inquiring service of the checking data; the checking mobile client is used for providing acquisition, modification and inquiring service of the checking data for clients. By adopting the system provided by the invention, goods checking and management can be realized by combining the owned mobile terminals of staff with the mobile client, so that the operating cost is low; checking information can be transmitted in a real-time manner by using the mobile terminal and wireless communication, so that the work efficiency is improved.
