Bolt stress monitor based on zigbee technology and its application method

Abstract

The invention provides a bolt stress monitor based on ZigBee technology and a method of use thereof, including a vibrating wire bolt collector, a ZigBee wireless transmitting module and a monitoring instrument, and the ZigBee wireless transmitting module is fixed on the vibrating wire bolt collecting instrument , and the ZigBee wireless transmitter module is connected to the vibrating wire sensor on the vibrating wire bolt acquisition instrument, which is used to wirelessly transmit the stress data collected by the vibrating wire sensor to the monitor. ZigBee is designed for extremely low power consumption and can be fully charged Power supply. In theory, a single battery can be used for more than 2 years. ZigBee can usually reach a distance of 30-50 meters indoors, and even 400 meters in open areas outdoors. In order to solve the problem that the existing bolt stress and strain collection method needs a lot of manpower, material resources and financial resources, and the connection line is easily damaged, resulting in the failure of monitoring. The invention belongs to the field of mine safety monitoring.

Description

technical field [0001] The invention relates to a bolt stress monitoring device, which belongs to the field of mine safety monitoring. Background technique [0002] The safe and effective development of deep energy and mineral resources is a major issue related to the sustainable development of the national economy and the security of the national energy strategy. With the continuous increase of mining depth, various disasters are increasing, such as mine rock burst and large deformation of soft rock, which pose a huge threat to safe and efficient mining, and bolt support is necessary for deep mining, so the research on bolt The stress in the rock mass can better provide technical support for safe and efficient deep mining. [0003] At present, there are vibrating wire bolt stress monitors for the collection of bolt stress and strain. The installation process of the vibrating wire bolt stress monitor is relatively complicated. It is necessary to drill a hole first and inser...
