Embodiment Construction

[0034] The invention provides a concrete humidity control system, which has an aggregate delivery unit 1 , a powder delivery unit 2 , a humidity detection control unit 3 and a mixing station 4 . The installation of the humidity detection control unit is required to be safe and reliable. For example, it should be installed on a moisture-proof and electric-shock-proof distribution box shell to prevent metal shavings and wire ends from falling into the vent hole of the controller, so as not to cause product failure and misoperation.

[0035] The humidity detection control unit 3 of the present invention includes a data acquisition unit 5, a data processing unit 6 and a control unit 7, wherein the data acquisition unit 5, the data processing unit 6 and the control unit 7 are connected through an interface module.

[0036] As an embodiment of the present invention, wherein the data acquisition unit 5 includes an acquisition humidity probe 5a, a flow counting unit 5b, a software modi...

Abstract

The invention provides a concrete humidity control system and method. The device comprises an aggregate conveying unit, a powder conveying unit, a humidity detecting control unit and a stirring station, wherein the humidity detecting control unit comprises a data acquisition unit, a data processing unit and a control unit; the data acquisition unit, the data processing unit and the control unit communicate through an interface module; the data processing unit is used for performing digital processing on an analog signal acquired by the data acquisition unit; and a filter unit is used for performing low-pass filtering on a digital signal and is used for confirming moisture content of concrete in the stirring station in real time.

Description

technical field [0001] The invention relates to a humidity control system and method, in particular to a concrete humidity control system and method in a mixing station. Background technique [0002] In the construction industry, the use of concrete occupies a large proportion in engineering and plays a decisive role in structural safety, reliability and durability, so it is very important for the quality control of concrete. In concrete mixing, the moisture content in concrete has a direct impact on the strength development, shrinkage, creep, carbonation, freeze-thaw and other durability of concrete. Therefore, controlling the moisture content of concrete is a factor that cannot be ignored in concrete mixing. . [0003] At present, the concrete moisture content control in the industry is to install a humidity sensor in the mixing station through the water control system, measure the concrete humidity in the mixing station online and transmit the signal to the control syste...
