Abstract
Traditional shaft temperature and humidity detection system is wired mode, the transmission distance is limited. In order to overcome this shortcoming, this paper designed a detection system, which is based on ZigBee wireless sensor network and digital temperature-humidity sensor. In the system, the data’s acquisition and transmission of master-slave nodes is realized by the star network, and the data is displayed on the host computer through serial port. The system can realize multi-point detection and real-time monitoring.
Highlights
The function of the monitoring system mainly includes collection, master, alarming, information transmitting and host computer displayed
Sensor is the perception of the monitoring system, which can transform the information into electrical signals, and the system can collect, transmit and analyze these signals, which can indirectly reflect the state of the underground environment; The main system control to extract the information of sensor and transmit the data to the channel of communication, and need to determine whether the collected information is normal
On the PC will display the data received in real time
Summary
The function of the monitoring system mainly includes collection, master, alarming, information transmitting and host computer displayed. Sensor is the perception of the monitoring system, which can transform the information into electrical signals, and the system can collect, transmit and analyze these signals, which can indirectly reflect the state of the underground environment; The main system control to extract the information of sensor and transmit the data to the channel of communication, and need to determine whether the collected information is normal. The part of information transmitting is responsible for sending the collected data to the host computer smoothly and displayed on it. In order to monitor the state of the underground environment all the time. The host computer by judging the machine over the information of data, displays that the state of underground environment is normal or abnormal, the alarm will rang when the data exceed the normal range. Dohare(2015) uses the wireless Communication and Environment Monitoring in Underground Coal Mines.
