The lack of mine belt conveyor fire early warning system of the original mainly manifested: Belt conveyor of coal mine special working environment is not conducive to fire warning system installation and repair detection; The roller at work does not stop rotating, Cause fire early warning system can not effectively monitor each idler roller. The author uses the DTS for belt conveyor used for reconstruction technical analysis. Specific technical reformation key issues include: Reasonable installation design makes the DTS system can be fully applied; In the roller for continuous temperature measurement of the flange joint attenuation data analysis Distributed temperature system ( DTS ) is a new high-tech products e reasons In the domestic fire warning system with application fields are currently not many .But it gradually expanded, From a single temperature detection, to the dam, tunnel fire warning. More applications are being developed as potential safety hazard in coal mines: very high places ,Need more advanced fire warning system , In the doctoral program foundation of State Education Ministry funded by Chongqing University in 1987 and the first in the country in the distributed optical fiber temperature measurement technology research, completed a feasibility study[1].Erdos Group Based on distributed optical fiber temperature monitoring system in coal mine belt conveyor fire warning system combining, obtained good results.

The cement market is increasingly competitive with the rise of imported cement, which of course must be answered by cement producers among competition. One of the main processes that should not be disturbed is the supply of limestone from quarry to the factory. The safety of people, processes and equipment are certainly necessity for the production process to run smoothly. The problem that can occur in limestone supply is a breakdown on the Overland Belt Conveyor (OLBC) which is caused by a broken roller and causes the belt to tear and potentially fire. For this reason, prevention efforts need to be done with an early warning mechanism to provide alerts to interested parties. Early warning system can be applied to the process because it can detect the beginning of heat so that fires can be prevented. Therefore, it is necessary to install a sensor using optical fiber called a linear heat detector (LHD) on OLBC. Installing the LHD system on OLBC can effectively detect an increase in roller temperature which then becomes an early warning for operators in the control room 24 hours a day to prevent incidents that cause harm to the company due to belt fires or torn belts.

In order to solve the shortcomings of the landslide monitoring technology method, a set of landslides monitoring and early warning system is designed. It can achieve real-time sensor data acquisition, remote transmission and query display. In addition, aiming at the harsh environment of landslide monitoring and the performance requirements of the monitoring system, an improved minimum hop routing protocol is proposed. It can reduce network energy consumption, enhance network robustness, and improve node layout and networking flexibility. In order to realize the remote transmission of data, GPRS wireless communication is used to transmit monitoring data. Combined with remote monitoring center, real-time data display, query, preservation and landslide warning and prediction are realized. The results show that the sensor data acquisition system is accurate, the system is stable, and the node network is flexible. Therefore, the monitoring system has a good use value.

Purpose Seepage of the dam is an important safety problem, which may cause internal erosion of the structure. In the field of seepage monitoring in civil engineering, the distributed optical fiber sensing technology based on the temperature tracing method has been paid more attention due to its unique advantages of high sensitivity, good stability and high resolution. The purpose of this paper is to make a review of the existing related research, so as to facilitate the later scholars to understand and further study more systematically. Design/methodology/approach In this paper, three kinds of commonly used distributed fiber temperature measurement technologies are introduced. Based on the working principle, monitoring system, theoretical analysis, experimental research and engineering application of the fiber seepage monitoring technology, the present situation of dam seepage monitoring based on distributed fiber is reviewed in detail and their advantages and disadvantages are compared. Findings The thermal monitoring technology of seepage measurement depends on the accuracy of optical fiber temperature measurement (including the accuracy of the system and the rationality of the discrimination method), the correct installation of optical fiber and the quantitative analysis of temperature data. The accuracy of the current monitoring system can basically meet the existing measurement requirements, but the correct installation of optical fiber and the calibration of temperature data need to be further studied for different discrimination methods, and this field has great research value. Originality/value At present, there are many applications and research studies of optical fiber sensing in the field of structural health monitoring, and there are also reviews of related aspects. However, there is little or no review only in the field of seepage monitoring. This paper summarizes the research and application of optical fiber sensing in the field of seepage monitoring. The possibility of the gradient method to find its new prospect with the development of monitoring systems and the improvement of temperature resolution is discussed. The idea of extending the seepage monitoring method based on distributed optical fiber thermal monitoring technology to other monitoring fields is also given in the paper.

Monitoring And Early Warning

According to the actual situation of large range road disasters in seasonal frozen area, the road safety can reflect by the slope stability, the subgrade stability, the bridge safety and the ice(snow) on the road.The objective of this paper is to present a new monitoring and early-warning system, which can be used on the large range road in seasonal frozen area. The system consists of four parts, which are slope monitoring system, subgrade monitoring system, bridge monitoring system and ice(snow) monitoring system. In this system, the small world theory is used to build an IPv6 p2p network structure and semi-structured data is used to store any type of early-warning data. In addition, a bridge in western Changchun City in Jilin Province was selected as the case study example. Monitoring and early-warning results show that the system is stable and efficient , also can improve the scalability and reduce the dependence on central server in IPv6 network.
