The present invention belongs to the field of building construction technology, and in particular, relates to an integrated assembled composite floor with thermal insulation and sound insulation structure, including a floor body, the upper end of which is fixedly connected with a plurality of connectors distributed in a rectangular array, a hollow layer having a thermal insulation effect is provided inside the floor body, and ventilation steel pipes connected to the outside are embedded in the inner walls of both sides of the hollow layer; and an adjustment component is used to adjust the thermal insulation effect of the hollow layer according to the outside temperature. The present invention can adjust the ventilation rate of the ventilation steel pipe according to temperature changes by setting an adjustment component, thereby adjusting the thermal insulation effect by changing the air convection speed; by setting an adaptive sound insulation component, the electric field strength around the deformable sound absorbing member can be adjusted according to the sound pressure of the outside world, and the sound insulation effect can be adjusted by changing the deformation degree of the deformable sound absorbing member.

The invention belongs to the technical field of building construction, and particularly relates to a heat preservation and sound insulation structure integrated assembly type composite floor slab which comprises a floor slab body, the upper end of the floor slab body is fixedly connected with a plurality of rectangular connecting pieces distributed in an array mode, and a hollow layer playing a heat preservation and insulation effect is arranged in the floor slab body. Ventilation steel pipes communicating with the outside are embedded in the inner walls of the two sides of the hollow layer. The adjusting assembly is used for adjusting the heat preservation and insulation effect of the hollow layer according to the external temperature. By arranging the adjusting assembly, the ventilation rate of the ventilation steel pipe can be adjusted according to the temperature change, and therefore the heat preservation effect is adjusted according to the change of the air convection speed; by arranging the self-adaptive sound insulation assembly, the electric field intensity on the peripheral side of the deformation sound absorption part can be adjusted according to the external sound pressure condition, and the sound insulation effect is adjusted by changing the deformation degree of the deformation sound absorption part.

A system and method for real-time monitoring of the temperature at the outlet of a concrete mixture, the system includes a temperature sensing device arranged at a receiving hopper, the temperature sensing device is connected to a measurement and control unit, and the measurement and control unit is connected to a front-end host. The system also includes a discharge sensing device, the discharge sensing device is used to sense the phase current of the mixing motor, the discharge sensing device is connected to the front-end host; the front-end host is connected to a server. The system also includes a client, the client accesses the server, performs basic data setting and information query on the system; the server is used to store the basic data of the system and the data uploaded by the front-end host, and performs calculations, processing and display on the data. Through a system and method for real-time monitoring of the temperature at the outlet of a concrete mixture, the outlet temperature of the concrete mixture can be obtained in real time, data support can be provided to ensure that the outlet temperature is qualified, and it is convenient for the concrete mixing system to take temperature control measures in a timely manner. Compared with the existing methods, the monitoring method of the present invention is more convenient and has a higher monitoring frequency.
