Design Of The Platform Of IoT For Water Resources Monitoring

China is rich in water resources, but because of its large population, per capitawater resource is lower than the global average. Furthermore, the frequent occurring offloods and droughts and the more and more seriously of water pollution in our country,leads to the shortage of water resources. Water monitoring is an import foundation meanto resolve the shortage of water resources undoubtedly. The current water resourcesmonitoring technology is given priority to with the remote automatic monitoring, and ismoving to the direction of the intelligent and networked development. The rise andapplication of the Internet of Things (IoT) technology can greatly improve the watermonitoring technology. IoT can not only blend in different applications, but also build aplatform for a field to provide services for different applications and realize the sharingof resources.This paper designs a platform of IoT for water resources monitoring, divides theplatform into perception layer, network layer and application layer, and realizes thesoftware and hardware systems of the perception later and application layer. In theperception layer of the platform, designs and realizes a gateway of IoT and theprototype system of ZigBee wireless sensor network. The gateway of IoT which usesS3C2410as the microprocessor and uses Linux as the embedded system can transfer themonitoring data of water resources. The gateway uses Ethernet and GPRS network totransfer the monitoring data, uses the RS485interface and ModBus protocol to collectmonitoring data of the intelligent monitoring instrument, uses the RS232interface tocollect data of ZigBee network. The prototype system of ZigBee wireless sensornetwork which was used to collect the data of water resources uses a hardware platformwhich uses CC2430as the core, uses Z-Stack as the ZigBee protocol stack. Based onthe hardware platform and ZigBee protocol stack, designs the software of ZigBee nodesand realizes the temperature acquisition. In the network layer of the platform, uses thecommonality network to transfer water resources data. In the application layer of theplatform, designs and realizes the remote automatic system on water resources, thesystem of data querying and the application system interface for redevelopment of theplatform.In the lab environment, tests the platform. With the test, the basic function of theplatform has been realized. The platform is a common platform for water resourcesmonitoring. On the basis of the realization of the remote automatic monitoring of waterresources, the platform can support intelligent monitoring instruments which use theRS485interface as the interface for outputting data and use the ModBus protocol as the protocol for transferring data connected to network, and it also can support watermonitoring data transmission terminals which comply with the data transmissionprotocols of the ministry of water resources. The platform can provide interface servicesfor the third-party of applications and a data querying platform of water resources datafor users. The platform has a good scalability and ability of redevelopment.
