| Abstract: | There exist many deficiencies in current monitoring systems,such as low accuracy,fixed sampling frequency,poor real-time and short transmission distance.The system in this paper integrated special stress-strain material,precisive constant current source,multi-resolution sampling and the CAN bus to overcome above deficiencies.The real-time dynamic monitoring of changes of crustal stress revealed their changing rule,and provided supports for the prevention and protection for these disasters as well.It will provide technical support for the safety of coal mine production. |
