Epidemic preventing and controlling system for detecting and searching people with abnormal temperatures

InactiveCN101999888APay attention to the epidemic situation in real timeEffective prevention and control informationDiagnostic recording/measuringSensorsScheduling instructionsComputer module
The invention discloses an epidemic preventing and controlling system for detecting and searching people with abnormal temperatures. The system comprises an information acquisition processing module, a communication processing module and a terminal processing module. The information acquisition processing module consists of an infrared detector, a camera and an information acquisition processor, wherein the infrared detector is used for acquiring face temperature information; the camera is used for acquiring face video information; and the information acquisition processor is used to perform motion target division and profile extraction on the face temperature information and the face video information so as to obtain information of people with abnormal temperatures. The communication processing module is used for transmitting the information of the people with the abnormal temperatures to the terminal processing module. The terminal processing module performs real-time dynamic searching of the people with abnormal temperatures in a monitored area and can send scheduling instruction information for giving an epidemic prompt and tracking people and the like. The system of the invention can monitor and recognize the people with abnormal temperatures in the monitored area and accordingly make a correct response and give good warning for coming epidemics, so that even epidemics outbreak, the people with abnormal temperatures can be found at first time and the epidemic preventing efficiency is improved as high as possible.

Prefabricated bearing platform suitable for large-diameter tubular column foundation of sea bridge and construction method thereof

The invention relates to a prefabricated bearing platform suitable for a large-diameter tubular column foundation of a sea bridge and a construction method of the prefabricated bearing platform. The prefabricated bearing platform is of a multi-box lattice type concrete structure, and a box chamber and the large-diameter tubular column foundation are uniform in arrangement. Movable steel bottom plates are arranged at positions, corresponding to tubular columns, of bottom plates, and connecting reinforcing steel ribs are arranged on the inner wall of the prefabricated bearing platform. The construction method includes the steps of prefabricating the bearing platform in a dry dock on the bank side, filling the dry dock with water after the bearing platform is prefabricated, enabling the prefabricated platform to float by itself, opening a lock when the water level inside the dock is flush with the water level of the sea surface, and dragging the prefabricated bearing platform to the position of a pier; filling the prefabricated bearing platform with water so that the prefabricated bearing platform can sink onto a temporary support, and erecting an operating platform on the top of the prefabricated bearing platform; taking down the movable steel plates, conducting tubular column sinking construction, pouring underwater bottom sealing concrete, pumping water, bonding the reinforcing steel ribs, pouring bearing platform concrete, and forming a complete bearing platform structure. According to the prefabricated bearing platform and the construction method, platform erecting expenses can be saved, materials are used completely, construction investment and time are saved, and the prefabricating bearing platform can bear force together with later period bearing platform concrete.

The invention relates to a method for building a municipal pipeline hydraulic model, relates to the technical field of municipal engineering information, and in particular relates to a method for building a pipeline hydraulic model. According to the method, the problem that the existing method for building the pipeline hydraulic model is long in computing time and difficult to estimate result error is solved. According to the method, a pipeline static database is built through obtaining the design information of a pipeline system; the number of minimal observation points is determined according to a pipeline flow equation and a pipeline energy equation; the node pressures and pipe section flow observation data under multiple working conditions are collected; the flow direction in each pipe section is determined and a directed graph which can represent the flow directions is obtained; then the resistance parameter of each pipe section is extracted, the directed graph is endowed with the values of the resistance parameters of the pipe sections, thus the building of the pipeline hydraulic model is completed and the reliability of the pipeline hydraulic model is verified until the pipeline hydraulic model meeting the requirement of pipeline analysis is obtained. The method is applicable to building the pipeline hydraulic model in the field of municipal engineering information technology.
