28.4 Conclusion
1. Using the guard sensor can effectively block the noise from outside the guard
sensor, so that the on-line acoustic emission detection problem under the noise
interference can be solved by using the guard sensor;
2. The coverage of the guard sensor is the same as that of the main sensor. Therefore,
the number of guard sensors should be the same as the number of the main sensors;
3. When using guard sensors for on-line acoustic emission detection, it is not
recommended to use regional positioning method for conclusion evaluation.
