Remote monitoring device for mountain cracks

Abstract

The invention discloses a remote monitoring device for mountain cracks. The device consists of a sensor node and a monitoring host. The device uses a GSM network to perform information transmission, adopts a cyclic working mode from working to stopping to monitor the mountain cracks, and meanwhile adopts digital filter and curve fitting algorithm to improve the precision of data acquisition; therefore, the device can implement high-precision and long-distance mountain crack monitoring, and greatly prolongs the working time.

Description

technical field [0001] The invention relates to the technical field of mountain crack monitoring, in particular to a high-precision, remote and energy-saving mountain crack monitoring device. Background technique [0002] The monitoring of mountain cracks is a commonly used geological disaster monitoring method. The key point of the monitoring of mountain cracks is the opening and closing of the crack itself, that is, the deformation of the crack. Its biggest characteristics are: first, the deformation of the crack is slow, and some changes only after several hours or even days; second, the monitoring conditions are poor. There is no mains access; third, on-site monitoring is more dangerous; fourth, the monitoring center is far away from the disaster site, and wired monitoring is limited. [0003] The current monitoring method mainly includes 1. Periodic measurement on the artificial site, that is, installing two positioning piles on both sides of the crack to be monitored ...

2. GPS monitoring technology, that is, by installing GPS equipment on the monitored point and obtaining the position coordinates to reflect the change of the crack. This method is generally only used for large-scale fixed-point measurement, and the cost is high, and it is less affected by the covering around the monitoring point. Big

In addition, for the crack monitoring of a monitored mountain, several key monitoring points are often selected, and the measured displacement information is required to be as accurate as possible. However, the general simple measurement methods such as infrared measurement cannot meet the accuracy requirements of actual monitoring.

[0004] At present, several deficiencies in the monitoring of mountain cracks are mainly concentrated in: 1. The degree of automation is not high, and manual on-site monitoring is not only dangerous, but also time-consuming and laborious.

2. The measurement accuracy is not high enough to meet the needs of analysis and decision-making

3. The energy consumption of the data acquisition node is high, and it generally needs to be equipped with a large-capacity battery or use a high-priced solar power supply scheme
