Information acquisition system based on Bluetooth Ad Hoc network

Abstract

The invention discloses an information acquisition system based on a Bluetooth Ad Hoc network, mainly solving the problem that the traditional data acquisition system does not have flexibility and expandability. The information acquisition system comprises a master information acquisition server (101), a master information acquisition node (102) and a slave information acquisition node (103), wherein the slave information acquisition node sends information data collected by an information acquisition module to the master information acquisition node by Bluetooth equipment; the master information acquisition node receives and collects the information data of the slave node and directly or indirectly sends the collected information data to the master information acquisition server by the Bluetooth equipment; and the master information acquisition server calculates, sorts and stores the collected information data sent from the master information acquisition node. The information acquisition system can perform multiple information acquisition methods, can adapt to varied information acquisition environments, effectively expand the information acquisition range and can be used for collecting information for medium and short distances.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a method for realizing information collection by using a Bluetooth ad hoc network, which can be used for information collection of short and medium-distance Bluetooth ad hoc networks. Background technique [0002] In today's information age, information data has been more and more valued by people, and information data collection has become the foundation of this information age. The traditional information collection method is to manually record data, and then carry out data statistics and sorting. This method of data collection is time-consuming and laborious, and the labor cost is high; there is also a method of directly transmitting the collected data to the main server through a wired network. The method of data collection, but the laying cost of the wired network and its poor flexibility have become the biggest disadvantage of this data collection method; in re...

The traditional information collection method is to manually record data, and then carry out data statistics and sorting. This method of data collection is time-consuming and laborious, and the labor cost is high; there is also a method of directly transmitting the collected data to the main server through a wired network. The method of data collection, but the laying cost of the wired network and its poor flexibility have become the biggest disadvantage of this data collection method; in recent years, there have been methods of data collection using wireless technology, such as WIFI or Bluetooth technology, the basics of these collection methods The idea is to connect the collection device with the recording device through a wireless method. When data collection is required, the collection device is placed within the wireless network range of the recording device, and the collection command is executed to collect data. Although this method can avoid manual recording in traditional data collection However, due to the limitation of wireless network communication distance, the collection process still requires full-time personnel to use professional equipment to the designated data collection location for data collection, which not only increases labor costs, but also Unable to realize real-time data collection
