Design And Implementation Of Wireless Receiving System On Amass Sensor Data

With the rapid development of communication technology, the wireless communication technology gradually holds the dominant position in the communication technology. It provides wireless transmission method for a large number of sensor data field, and then has two problems.The first one is how to realize the automatic transmission of sensor data in the field. The second one is how to scientifically and effectively manage the collection of massive data. A kind of wireless receiving system on amass sensor data is designed in the paper, it effectively solves the above problems, and realizes periodically gathering the amass sensor data, security transmission, receiving and storaging.Firstly, the paper analyzes the cycle of the business process on the observation data transmission, designes the system structural drawing and introduces the basic composition and function of the wireless receiving system.Secondly, it introduces the function of how to collect data, by arrangement and importing of the task table, it has achieved the nodes for monitoring to collect data regularly.Once again, the sub-centers for monitoring and the gathering nodes are connected with the bluetooth serial port mode, and it realizes the data transmission. In order to realize the safe transmission of data between the sub-centers for monitoring and the remote monitoring center, before the data is stored, the sub-centers for monitoring deals the important data with DES encryption technology, then the collected sensor datas are uploaded to the remote server via FTP, and decrypted in the server. The approach assures the data to transmit safely.Finally, to counter the problem of receiving huge data which is hard to manage, it adopts MongoDB database to store the data, and designs the scientific storaging solution for mass database. Due to the data stored with great redundancy, through the revolving door compression algorithm deals with the data, so it realizes efficiently storing the sensor data in the receiving module.The complete system has been applied to the actual of Institute of Chinese academy of sciences and the result is good.
