Abstract

The present invention proposes a concrete slump monitoring device and method, wherein the concrete slump monitoring device includes: a current acquisition device, a PLC, and an industrial computer; Stir the current information of the host motor, and transmit the current information to the PLC; the industrial computer is used to receive the current information transmitted by the PLC, and compare the current information with the preset current threshold corresponding to the current number of target concrete plates, and determine according to the comparison result The slump state of the target concrete. The present invention can effectively determine the state of slump.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a concrete slump monitoring device and method. Background technique [0002] Due to the continuous advancement of my country's urbanization process, concrete equipment is more and more widely used in the construction of roads, bridges, urban construction and other projects, and the requirements for mixing stations are also increasing. Since aggregates are usually exposed to the outdoors during use, coupled with the influence of weather, the moisture content of aggregates cannot be guaranteed, which will affect the slump of concrete and ultimately affect the quality of concrete. [0003] At present, the way to control concrete slump is mainly based on the operator's experience. Inexperienced operators can only check whether the slump of the concrete is appropriate through the final shape of the discharged material. Such an operation is obviously inconsistent with today's high...
