The industrial geographical information system relates to the field of industrial production intelligent management and control and comprises a device acquisition control end, a spatio-temporal big data processing end and an industrial geographical information system platform end. Based on a spatial data unified management and analysis framework of the geographic information system, various sensors, monitoring devices and mobile devices in an industrial production environment are acquired to perceive real-time data, and the real-time data are cleaned, denoised, cached, distributed, stored and processed permanently. Various types of static spatial data are import and entered, a composite spatio-temporal object model is employed to make macroscopic and microscopic visualization, collaborative processing update, spatio-temporal analysis and linkage analysis of industrial production scenes and processes, and collaborative joint control of industrial production processes and devices are conducted based on the device acquisition control end.

A data loading and storage system includes a storage module, a buffering module, a control module, a plurality of data loading modules, a plurality of data storage modules and a multi-core processor array module. The data is continuously stored in a DDR, and the data computed by the multi-core processor may be arranged continuously or be arranged according to a certain rule. After DMA reads the data into the DATA_BUF module by a BURST mode, in order to support fast loading of the data into the multi-core processor array, the data loading modules (i.e., load modules) are designed. In order to quickly store the computed result of the multi-core processor array into the (DATA_BUF module according to a certain rule, the data storage modules (i.e., store module) are designed.

Design and construction method for improving an expansive soil embankment using phosphogypsum and microbes, including the following steps: (1) placinginto a culture medium to prepare a microbial solution, and mixing urea and calcium chloride with water to prepare a cementing fluid; (2) mixing and stirring a mixture, the microbial solution and water, adding the cementing solution well, and mixing the cementing fluid with water to prepare an improved mixture; and (3) leveling and compacting original ground, laying geomembranes, the improved mixture, and geogrids, laying a last layer of geomembrane on the top surface of the embankment after pavement of the embankment, and paving a roadbed. The design and construction method can meet construction requirements of highway embankment projects and roadbed projects of first-grade and other grades of roads, and consume solid waste phosphogypsum.

Disclosed are a multi-carrier superposition method and device. First, input carrier signals are superposed, and gain reduction processing is conducted during the superposition process, and then CFR processing and increase processing are conducted on the superposed carrier signals. Thus, under the circumstance of multi-carrier superposition, it can be effectively ensured that signals cannot overflow, and meanwhile the requirement for precision of a system during processing is met.
