Rapid Deployment Of Emergency Monitoring System Of Dangerous Chemicalgas Based On WSN

With the rapid development of economy and society, environmental pollution accidents occurred frequently, especially the risk of abruptness of dangerous chemical gas caused serious damage to people's property and the ecological environment. Therefore, in order to reduce the risk of harm and loss caused by the gas accidents, the State Environmental Protection and other relevant departments are studying countermeasures for achieving the emergency response to the accidents.At the present time, in the risk of sudden gas pollution incidents, although many monitoring equipments meet the emergency small, portable, etc., but they are independent and relatively dispersed, have no function of setting up wireless network, could not send the collection of data to the scene command post and remote monitoring & management platform and environmental protection departments and other emergency services can not share the accident information, and thus be difficult to implement emergency response among the different departments. So this paper proposes a risk for rapid deployment of emergency monitoring system of dangerous chemical gas based on wireless sensor networks. The thesis work and the results are as follows:1. This paper discussed risk for rapid deployment of emergency monitoring system of dangerous chemical gas based on WSN, respectively, proposed the corresponding design of each of the three components of the system: WSN node, GPRS transmit module and the monitoring & management platform.2. The paper adopted the TI CC2530 RF chip to design WSN node, respectively, completed the coordinator node and the mobile terminal node in human-computer interaction, data acquisition and communication interface, the antenna module and other aspects of hardware design .The nodes connected to monitoring equipment could be quickly deployed to the accident scene and built up a wireless sensor network to realize the scene of the accident data collection and transmission.3. For the purpose of long-distance wireless transmission GPRS transmit module was designed in this paper, using the STC Series MCU and MC37I module completed the hardware design, and through the transplant of uIP protocol stack, completed the TCP communication.4. The monitoring and management platform was developed in the paper, network communications was implemented, and the accident scene data could be displayed real-time to the browser for browsing. Meanwhile, the platform used Web Services technology to achieve scene of the accident data and other information for sharing, so it could enhance the emergency response between environmental protection departments and other departments.
