The vertical additional force could make the shaft lining in deep topsoil fracture. The force is caused by the bottom aquifer drainage settlement. In order to analyze the mechanical state of shaft, a shaft lining automatic monitoring system is built. The overall safety can be valuated by it. When monitoring data show that the shaft lining will be fractured, management measures can be timely taken to prevent more damage. In the process of ground grouting treatment to prevent shaft fracture, the monitoring data can be as the shaft lining stability and grouting parameters adjustment basis, to ensure safety and grouting reinforcement effect.

The shaft lining in deep topsoil will be lead to fracture by the vertical additional force, which is caused by the bottom aquifer drainage settlement. Through the establishment of the shaft lining automatic monitoring system, the mechanical state of shaft can be effectively analyzed and the overall safety can be valuated. When monitoring data show that the shaft lining will be fractured, the rocks, management measures can be timely taken to prevent more damage by a ruptured shaft. In the process of ground grouting treatment to prevent shaft fracture, the monitoring data can be as shaft lining stability and grouting parameter adjustment basis, to ensure safety and grouting reinforcement effect.

Monitoring Information

The technology for curing rapture and strain monitoring of coal mine shaft in special stratum is discussed in this paper. The mine shaft lining in the deep and thick overburden is put a vertical additional, which is caused by the draining consolidation settlement of bottom aquifer. When the force together with others forces is more than the ultimate strength of concrete lining, the shaft lining will be lead to fracture. In order to treat the broken shaft lining, the integrated management method of dense shaft circles, the grouting, and loop relieving-pressure grooves was taken. The monitoring information of the remote shaft lining strain automatic monitoring system can be used to predict and evaluate the safety state of the shaft lining. The suggested mechanism and technology are able to prevent and cure shaft lining rapture in other similar mine. The treatment attained to the ideal effect and the method has an important reference value for the prevention and curing of shaft lining rupture in the same strata.

As the urban subway leapfrogs in recent years, there are abound with close-spaced construction of metro tunnels. With the development of computer and software technology, virtual instrument will be widely developed in the testing field. The essay focuses on the usage of virtual instrument to develop a set of LabVIEW-based multi-sensor automatic monitoring system for the construction and protection of the adjacent metro tunnels. And with the comprehensive analysis of the monitoring data, the system can forecast the potential danger in a project. This monitoring system provides guidance for the adjacent construction and provides similar projects for reference.

The truck scale is more and more applied on the weighing system. To seek illegal profits, many kinds of truck scale cheating method is found in the weighing system. To monitoring the truck scale cheating method, the truck scale cheating automatic monitoring system based on the GPRS is brought out in this paper. The truck scale cheating automatic monitoring system is designed. The monitoring system includes three parts: the monitoring terminal, the GPRS transmission module and the upper monitoring system. The truck scale measurement data of the sensors are collected by the monitoring terminal and sent to the upper monitoring system through the GPRS module. The experimental system is established on the pneumatic conveying system and the experiment is carried out. The experimental results show that the automatic monitoring system can on-line monitor the truck scale cheating method and improves the security of the truck scale weighing system.

Automatic Monitoring System

Total phosphorus is an much important key water quality parameter . In view of the technical defects of existing detection methods and instruments for in situ monitoring total phosphorus, a new detection method based on ultrasonic assisted sample digestion and spectrum analysis was put forward in this paper, and the automatic monitoring system prototype based on such detection method had been developed. Aiming at wastewater treatment, the spot experiment had been carried out to contrast prototype with Chinas national standard analysis method for on line measuring total phosphorus in the water, and the results of the comparative experiment showed that the automatic monitoring instrument prototypes had good repeatability (10%) and high accuracy (±10%), which met the technical qualifications of Chinas environmental protection industry standards.
