[Abstract]:As an important part of fully mechanized coal mining, the mine hoist is not only responsible for the task of transporting coal mining resources, but also a key channel for the intercommunication of personnel and materials inside and outside the mine. However, its poor working environment leads to the failure of working parts. It is very important to monitor the working condition of hoist in order to find the hidden trouble in time. At present, the remote monitoring research on the running condition of hoist is slow, and the actual monitoring effect brings about the improvement of the fault of hoist, which is difficult to match with the important position of hoist in coal mine safety production. It has a large depth of space. In this paper, the basic structure, working principle and operation failure of the hoist are analyzed in depth, and the specific requirements of the working process and safe operation of each system in the operation process of the hoist are analyzed in detail, and the relationship between the common faults is further analyzed. The collection parameters which can represent the running state of the hoist are selected. In view of the problem that the stability of network transmission leads to the limitation of data transmission ability and the limitation of region causes the managers to view inconvenient problems, according to the operating state characteristics of mine hoist under working conditions, This paper expounds the theoretical research and practical application significance of remote monitoring based on GPRS and Web, and puts forward the remote monitoring mode of hoist running status based on "Web issue of terminal collection and wireless transmission". By introducing GPRS network technology and Web page technology, a practical system of collecting and remote monitoring of hoist running state terminal is constructed. Based on C8051F single chip computer and GPRS, this paper designs the hardware and software of the monitoring system, extracts the running information of current, pressure and temperature as the system parameters, and completes the equipment selection and platform construction in the hardware part. The software part completes the development of GPRS data receiving software and Web remote monitoring platform and the design of database. Integrating the existing resources of the laboratory to build the hoist monitoring platform, the real-time data collection is packaged and sent to the network center through GPRS module according to the predetermined format, and the data is received by the development software and stored in the network center server. And the monitoring information is published through the Web. The remote monitoring platform is developed to receive, process and display the key operation information of hoist. Based on the combination of remote monitoring and modern communication technology, a basic remote monitoring system of hoist key operation information based on single chip microcomputer and wireless network is set up, and the experiments and system tests are carried out. The test results show that the system can meet the functional requirements of the remote monitoring system of hoist, and the system runs stably and reliably, achieves the preset goal, and has broad prospects and important practical significance for the application of entities in different fields.
