Grid Division

WSN (wireless sensor network) is a perfect tool of temperature monitoring in coal goaf. Based on the three-zone theory of goaf, the GtmWSN model is proposed, and its dynamic features are analyzed. Accordingly, a data transmission scheme, named DTDGD, is worked out. Firstly, sink nodes conduct dynamic grid division on the GtmWSN according to virtual semicircle. Secondly, each node will confirm to which grid it belongs based on grid number. Finally, data will be delivered to sink nodes with greedy forward and hole avoidance. Simulation results and field data showed that the GtmWSN and DTDGD satisfied the lifetime need of goaf temperature monitoring.

Software And Hardware

To realize the design of mobile 4G gateway of ZigBee wireless sensor network (WSN), a scheme of wireless remote monitoring based on ZigBee and general packet radio service (GPRS) WSN gateway system is proposed. The scheme combines the advantages of short distance, low power consumption, low cost and long distance popular communication of ZigBee technology, and uses the system architecture of ZigBee + GPRS + Android. On this hardware platform, the transplantation of Android system and the development of related hardware device drivers are designed and implemented, so as to build the software platform of the system. Based on the software and hardware platform of the system, the related applications are designed and realized according to the function requirements of the system, and the software and hardware platform and the application program are tested and analyzed. The test results show that the system runs steadily and has good performance. To sum up, the hardware platform has the advantages of low energy consumption, high performance and scalability.

The Cost

ZigBee technology is widely used in wireless sensor networks with the advantages of low power, low cost, convenient networking, etc. Design of ZigBee-based wireless sensor network nodes have become a demand. The nodes are generally placed in some occasions where the power supply inconvenient and require battery-powered, so the low-power of the nodes is an important indicator. The node chose CC2530 as the hardware core and transplanted Z-Stack protocol stack. It collected different data through different sensors and used ZigBee technology for wireless communication. This article describes the process of node hardware design, and reduces the power consumption of the node with choosing low-power devices, reducing the operating frequency and other methods. Low-power node saves the cost and increases the life of the nodes and the network. So it is good for increasing the continuity and stability of the network.
