Device and method for intelligently metering and monitoring blending process for mixing plant

Abstract

The invention discloses a device and a method for intelligently metering and monitoring a blending process for a mixing plant, belonging to the technical field of the transportation and construction industries. The device comprises at least two storage bins, a weighing sensor, a monitoring instrument, a PLC (Programmable Logic Controller), a GPRS (General Packet Radio Service) and a terminal computer, wherein a discharging door of each storage bin is connected with the monitoring instrument by a signal wire; the weighing sensor is arranged below the storage bin; the weighing sensor is connected with the monitoring instrument by two signal wires; the monitoring instrument is connected with the PLC by an RS 485 bus, wherein the monitoring instrument internally comprises a setting unit, a signal receiving unit, a signal converting unit, a data computing unit and a data display unit; and the PLC is connected with the terminal computer by the GPRS. According to the invention, a monitoring staff can acquire the relevant data even without arriving at the scene, and actual unloading amount of the material can be timely checked, so that the working staff can effectively monitor in real time, and much manpower and many material resources can be saved.

Description

technical field [0001] The invention belongs to the technical field of transportation and construction industries, and in particular relates to an intelligent metering and monitoring device and method for mixing equipment batching process. Background technique [0002] Today, with the development of data and intelligence, the requirements for the measurement of mixing equipment ingredients in engineering are getting higher and higher. The original signal collection-signal conversion-data integration mode has many disadvantages: the collection process and the signal conversion process are not supervised. If it is in place, there may be artificial modification of the information, resulting in the final uploaded data not being true enough, and such falsified facts are difficult to be discovered; moreover, the accuracy of the data collection by the equipment is not high enough, and it is difficult to achieve the accuracy of the data.

[0002] Today, with the development of data and intelligence, the requirements for the measurement of mixing equipment ingredients in engineering are getting higher and higher. The original signal collection-signal conversion-data integration mode has many disadvantages: the collection process and the signal conversion process are not supervised. In place, there may be artificial modification of information, resulting in the final uploaded data not being true enough, and this fact of falsification is still difficult to be discovered; moreover, the accuracy of data collection by equipment is not high enough, and it is difficult to achieve data accuracy
