Abstract

The invention provides an anchor rod stress monitor based on ZigBee technology and an application method thereof. The anchor rod stress monitor comprises a vibration wire type anchor rod acquisition device, a ZigBee wireless transmission module and a monitor, wherein the ZigBee wireless transmission module is fixedly arranged on the vibration wire type anchor rod acquisition device and connected with a vibration wire type sensor on the vibration wire type anchor rod acquisition device and used for transmitting in a wireless manner the stress data acquired by the vibration wire type sensor. With the design of extremely low power consumption, ZigBee can be totally battery-powered, and one battery can theoretically serve for more than 2 years; the indoor action range of ZigBee generally can reach 30-50m and even 400m in an outdoor open field. The problems of existing anchor rod stress-strain acquisition way that much consumption of labor, material and financial resources is needed and the connection wire is easily damaged and consequently monitoring failure is caused are solved. 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...
