Low-power Design Roof Separation Monitoring System

Of coal resources in the country, our country has always been mine accidents, especially within the tunnel roof accident especially, roof separation monitoring is particularly important. Roof separation monitor is measuring internal and external bolting roadway roof separation value anchorage zone of the instrument. By monitoring the data, data analysis and processing, can grasp the real-time dynamic roof separation in order to take appropriate measures to avoid the occurrence of accidents.Based on the domestic roof separation monitoring system products and research conducted research and analysis designed to overcome shortage of these products, research and design came out of a low-power roof separation monitoring system. This system is based on ZigBee wireless sensor network technology, wireless sensors and wireless roof separation consisting of a low-power sub-station roof separation observing systems. The system can be used independently, can also join the underground automation network for a variety of applications roof separation observations provide a powerful tool. Wireless sensor networks using whole tree, make sure the narrow roadway data transmission, using local network structure, so that each node only the immediately adjacent and sub-node communication, to ensure that when one node fails communication open, while reducing power consumption. Separation instrument uses a segmented capacitive displacement sensor can be used independently, or as a wireless network nodes, when used independently, the separation instrument display using light-control technology to ensure low power consumption for battery-powered energy when. When used as full function devices of wireless network nodes, in addition to the separation apparatus with a sensor function, or with a router function, the data can be forwarded to the adjacent two wireless nodes. Sub-station with data storage, protocol conversion, historical data view, separation of space-related data analysis, time-dependent analysis functions. The system can be used independently as a management device, for recording, viewing data for each node can be used as a bridge to the separation of data into the automation network. Mine does not have Ethernet in the sub-station via the USB interface can also back up data to the U disk, U disk and then through data sharing.Implementation of the system low-power network-style roof separation observing system allows bolting roadway roof separation monitoring more timely, convenient, accurate and reliable field data and history of the mine roof management of production safety and reduce and strictly control the number of people into the wells, improve staff efficiency, reduce mine production costs, excluding roof safety accidents, significant social and economic benefits.
