Embedded production monitoring system and monitoring method for concrete batching plant

Abstract

The invention provides a concrete batching plant embedded production monitoring system and a monitoring method thereof. The system comprises an intelligent electric energy meter, an embedding monitoring module, a model switching switch, a host PC and a remote monitoring server, wherein the embedding monitoring module and the model switching switch are respectively arranged on a special-purpose circuit board in the intelligent electric energy meter; the embedding monitoring module comprises a single-chip microcomputer, an SD card, a real-time clock circuit, and an RS232 / RS485 interface conversion circuit; the single-chip microcomputer is in signal electric connection with the host PC and the intelligent electric energy meter through the RS232 / RS485 interface conversion circuit; the single-chip microcomputer is in electric connection with the model switching switch; and the host PC and the remote monitoring server are connected in communication through the Internet. The monitoring method is realized mainly by monitoring the working current and working time of a mixer. The advantages are as follows: the structure is simple, the use is convenient, the cost is quite low, the popularization is facilitated, and the monitoring method can be easily realized and is practical and effective, thus the concrete production quality can be ensured through monitoring.

Description

technical field [0001] The invention relates to the technical field of quality monitoring of concrete mixing plants, in particular to an embedded production monitoring system for real-time monitoring of the working time of mixers in concrete mixing plants and a monitoring method of the monitoring system. Background technique [0002] When concrete production enterprises process concrete, they usually need to put raw materials such as cement, water and aggregate into the mixer according to the designed ratio for mixing. Only when the raw materials are mixed in the mixer for the set mixing time can they be mixed uniformly. Concrete that can meet the design requirements in terms of strength, workability and performance. Generally, the set mixing time is the minimum mixing time required for this type of raw material and the proportioned concrete, also known as the minimum mixing time. If the mixing time of the raw materials in the mixer does not reach the corresponding minimum m...

Problems solved by technology

However, most of the common concrete quality monitoring systems at present have monitoring blind spots in the mixing time of concrete mixers: under the pressure of fierce market competition, some concrete manufacturers often shorten the mixing time of mixers in order to maximize efficiency and benefits. In order to produce more products and faster products, and artificially set and modify the mixing time of the mixer in the database of the concrete quality monitoring system to meet the standard requirements, so as to avoid the supervision and inspection of the concrete production supervision department
