Abstract Nowadays the development of Internet of Things (IoT) technology has witnessed great changes in the world. As it has often been mentioned, IoT Environment Monitoring Technologies and IOT Smart Home Technologies have been gradually accepted by people and have good prospects for development. Now we can research a networking based intelligent platform to monitor our forest environmental factors in time with the new IoT technology based on ZIGBEE protocol. ZIGBEE based networking technologies has the advantages of low power dissipation, low data rate and high-capacity transportation, which makes it more suitable for the design of the node of forest environmental factors collection platform. So, we are going to discuss a kind of IoT forest environment factors collection platform based on ZIGBEE protocol.

Mine Accident

China’s present communication systems in coal mine can not effectively transfer information. Hence, rescue efforts are hard to be carried out in case of coal mine accident. To deal with this problem, a method of mine wireless communication system with low-power dissipation based on Zigbee wireless technology is presented. The paper at first introduces the characteristics and structure of ZigBee protocol, then introduced wireless communication networking mode of ZigBee device in coal mine underground, and gave principle of personnel position of coal mine underground and its realizing process.

Processing Circuit

At present, sub-micro-Newton (sub-μN) micro-force in micro-assembly and micro-manipulation is not able to be measured reliably. The piezoelectric micro-force sensors offer a lot of advantages for MEMS applications such as low power dissipation, high sensitivity, and easily integrated with piezoelectric micro-actuators. In spite of many advantages above, the research efforts are relatively limited compared to piezoresistive micro-force sensors. In this paper, Sensitive component is polyvinylidene fluoride (PVDF) and the research object is micro-force sensor based on PVDF film. Moreover, the model of micro-force and sensor’s output voltage is built up, signal processing circuit is designed, and a novel calibration method of micro-force sensor is designed to reliably measure force in the range of sub-μN. The experimental results show the PVDF sensor is designed in this paper with sub-μN resolution.

In this paper, the design of a Finite Impulse Response (FIR) filter based on the residue number system (RNS) is presented. We chose to implement it in the (RNS), because the RNS offers high speed and low power dissipation. This architecture is based on the single RNS multiplier-accumulator (MAC) unit. The three moduli set {2n+1,2n,2n-1}, which avoids 2n+1 modulus, is used to design FIR filter. A numerical example illustrates the principles of residue encoding, residue arithmetic, and residue decoding for FIR filters.
