Monitoring system based on unmanned aerial vehicle and wireless sensor network

Abstract

The invention discloses a monitoring system based on an unmanned aerial vehicle and a wireless sensor network. The monitoring system comprises an unmanned aerial vehicle device and an environment hazard detection device, wherein a first storage module, a first communication module, an image module and a sensor module of the environment hazard detection device are all in communication connection with a first processor module; a first power supply module is used for supplying direct-current power supply to the detection device; a fly control module, a GPS module, a second storage module and a second communication module of the unmanned aerial vehicle device are all in communication connection with a second processer module; a second power supply module is used for supplying power to an unmanned aerial vehicle; when the unmanned aerial vehicle device flies into the communication range of the environment hazard detection device, the first communication module and the second communication module are connected in a wireless communication mode. The purposes that the cost is lowered and limit of networks such as the 3G network, the 4G network and the satellite communication is avoided are achieved.

Description

technical field [0001] The invention relates to the field of field environmental disaster information detection, in particular to a monitoring system based on unmanned aerial vehicles and wireless sensor networks. Background technique [0002] Since ancient times, various natural disasters have been threatening human life and property safety. With the development of science and technology, many natural disasters cannot be blocked or eliminated. At the same time, prevention and early warning technology and environmental monitoring technology have also been greatly developed. Especially since the beginning of the 21st century, the development of information technology and the emergence of the Internet of Things have brought new opportunities for the advancement of prevention and early warning technology and environmental monitoring technology. [0003] The Internet of Things is an important part of the new generation of information technology. The core and foundation of the I...

Problems solved by technology

[0008] Advantages and disadvantages of this patented technology: This system has complete functions, but it needs to deploy a large number of relay nodes during use, which costs a lot; data is transmitted one by one by relay nodes, if a remote node fails, all data will be interrupted, and need Manually repair or replace nodes, a large number of relay nodes bring high maintenance costs

[0010] Advantages and disadvantages of this patented technology: This system only uses remote sensing to measure rainfall to determine whether debris flow occurs under this condition, but the early warning system has no other data monitoring other than rainfall, and does not have the ability to process massive data. Its prediction accuracy and reliability too low

[0013] Advantages and disadvantages of this patented technology: the system uses a field monitoring system based on long-distance wireless mesh network data transmission, which effectively solves the problem of long-distance data transmission, but the mesh nodes still need to be manually deployed in the field, and the deployment cost is relatively high. With the increase of time, there is a hidden danger of data interruption

[0016] Advantages and disadvantages of this patented technology: the system uses mobile communication network (3G) transmission, MMS, SMS signaling channel transmission, and relies heavily on telecom operators to transmit data. In addition to paying high communication fees, it is also limited by network operations The network bandwidth of the provider, more importantly, some remote areas may not have telecommunications network coverage

[0019] A variety of patented technologies for field environmental monitoring have their common disadvantages: data transmission depends on network operators, facing the dilemma of no signal coverage in some wild areas, rate limitations, or the need to deploy a large number of relay nodes, and a terminal node may be damaged. Facing the possibility of data interruption

[0020] However, most of the monitoring areas are located in inaccessible and remote areas, lacking the signal coverage of widely used communication means such as 3G and 4G. Therefore, how to transmit the data collected by WSN to the server has become a key problem. The usual solution is to establish a direct Putting stations or using satellite communications, the resulting disadvantages are high cost and need for approval
