Core-wall grave-mixed soil material backhoe blending remote action acquisition system and method

Abstract

The invention relates to a technology for monitoring the blending quality of gravel soil material in the core wall of a rockfill dam with a gravel soil core wall, and aims to solve the shortcomings of the current information collection method for the backhoe blending operation information of the rockfill dam core wall with a gravel soil core wall and the technology problem. The present invention relates to a backhoe blending remote action acquisition system and method for core wall mixed with gravel soil materials. The system includes a mobile station, a data center and a monitoring center; the specific steps are: 1), multi-source information collection and preliminary processing for backhoe blending operations ; 2), using data communication based on cellular mobile communication technology to transmit the collected data to the data center; 3), blending operation information integration, storage and alarm; 4), video synchronous playback and on-site management. The invention is mainly applied to the occasion of monitoring the quality of mixing gravel soil material in the core wall of a rockfill dam with a gravel soil core wall.

Description

technical field [0001] The invention relates to a technology for monitoring the blending quality of the core wall of a rockfill dam with a gravel soil core wall, in particular to a backhoe during the blending process of the core wall of a rockfill dam with a gravel soil core wall Blending action remote collection method. Specifically, it relates to a remote collection method for backhoe blending action of a core wall mixed with gravel and soil material by cellular mobile communication. Background technique [0002] In the filling construction of rockfill dams with gravel soil core walls, using backhoe excavators to mix gravel soil materials for core walls is an important means to control the quality of dam materials. Dig up, lift up to a height of 2 to 3 meters, and then sprinkle the dam material. Generally, the same dam material needs to be repeated for 3 series of actions. However, at the construction site, the operation of the backhoe excavator during the mixing process...

Problems solved by technology

A Chinese patent discloses a "real-time monitoring system for excavators" (patent application number: 201520694589.X), which allows operators in the cab to accurately observe the working status of the excavator, but cannot realize remote collection of the working status of the excavator ; Chinese patent discloses "a remote monitoring device for excavator working status" (patent application number: 200920298783.0), which consists of a processor, a wireless communication module, a host wireless communication module, a power conversion module, a battery, an angular velocity sensor and a wireless communication module Composition, it can transmit the angular velocity of the excavator's boom, stick, and bucket to the main engine in time, and the main engine can get the working status of the excavator after calculation and processing, and then send it to the monitoring center. However, this device is not fully applicable to many Simultaneous on-site operation, complex construction environment, and difficult communication conditions for the mixing of gravel-soil dam core wall with gravel soil core wall

[0004] In order to realize the remote monitoring of the core wall gravel-soil blending operation, the following key problems need to be overcome: 1. In the traditional blending operation, the collection, transmission, management and feedback of process data are ignored, which may cause the blending operation to fail to meet the construction quality requirements, and cannot record and trace the mixing process data, it is difficult to provide basis for quality evaluation and operation and maintenance; The data centers in the camps are far away, and they are all located in high mountains and valleys. It is difficult to transmit and integrate monitoring data, and it is difficult to realize remote collection of construction information; Affected by various factors in the field environment, it is difficult to meet business requirements, and it is difficult to integrate multiple sensors
