The existing wired monitoring systems for coal mine main-fan has some shortcomings such as complex working environment, bad flexibility and low reliability and so on. This paper developed a main-fan automatic monitoring system based on wireless sensor network with ZigBee technology, including monitoring host, sensor node, coordinator node and several data acquisition sensor. In order to meet requirements of coal mine environment monitoring signals, CC2430 is chosen as master control chip. The system achieved functions of automatic monitoring of coal mine main-fan supported by ZigBee technology, which is stable, low power consumption, and has practical value and bright development prospect.

The existing wired monitoring systems for edible fungus cultivation has some shortcomings such as complex wiring, unsatisfied function, low automatic level and so on. This paper developed a composite environment monitoring system for edible fungus cultivation based on wireless sensor network with ZigBee technology. Through a star wireless sensor network topology, this system acquired the temperature and humidity of cultivation environment, as well as the growing image of edible fungus. Meanwhile, according to the growing nature of edible fungus, a control strategy for cultivation environment was developed and integrated in the system. The proposed composite environment monitoring system provided a good solution for edible fungus cultivation industry.

Detection And Localization

The processes of development of hydrocarbon deposits are accompanied, as a rule, by an increase in the level of seismicity and, in particular, by the occurrence of technogenic earthquakes and other deformation phenomena associated with changes in the geodynamic regime. To monitor deformation and geodynamic processes, a seismic monitoring service should be organized. A similar monitoring system is also required for the analysis of aftershock and volcanic activity. Monitoring technology should be based on the use of reliable and fast methods of automatic detection and localization of seismic events of various scales. Traditional approaches to the detection and localization of earthquake epicenters and hypocenters are based on the analysis of data recorded by one or more single seismic stations. In that case, seismic event coordinates are estimated by means of signal extraction from noise and accurately measuring arrival times of a number of specific phases of the seismic signal at each recording point. Existing computational techniques have inherited this traditional approach. However, automatic procedures based on the ideology of manual processing turn out to be extremely laborious and ineffective due to the complexity of algorithms adequate to the actions of an experienced geophysicist-interpreter. The article contains a description of new approaches to the synthesis of automatic monitoring systems, which are based on the principles of emission tomography, use of spatial registration systems, energy analysis of wave fields and methods of converting real waveforms into low-frequency model signals (so-called filter masks/templates). The monitoring system was successfully tested in the process of detecting and locating the epicenters and hypocenters of 19 weak local earthquakes in Israel, as well as a quarry explosion.
