“…Meanwhile, there are many mature studies [11]- [13] on power supply technology. Compared with the laser power supply [14] and the solar power supply [15], the induction power supply is more suitable for this situation. Energy is acquired by the coils of the transformer and the power supply can be continuously maintained to ensure uninterrupted operation of the equipment.…”

Current measurement is one of the most important work in online monitoring of the electric system. Self-powered and intelligence are key areas of the current measuring sensor. In this paper, a self-powered current measuring sensor realizing measurement and power supply synchronously was designed. The different functions of current transformer were integrated and the mathematical relationship between the line current and the CT secondary side output was deduced. The model for current measurement based on different signals before or after the rectifier bridge was constructed. The overall design of the current measuring equipment was given. Finally, the accuracy of different measuring models was verified by experiments and test results under load changes were analysed.

We propose decoupling energy and sensing planes in WSN. This decoupling represents a paradigm shift as it can alleviate the fundamental problem of energy depletion in WSN and can (in theory) offer a sensor network with infinite lifetime. We present energy transference as the mode of decoupling energy by allowing energy to move between energy-rich and energy-poor nodes. We present a first practical energy distribution architecture that allows us to decouple energy supply from sensing activities. Such a separation of responsibilities enables us to utilize abundant energy sources distant from the sensing location, allowing unrestricted lifetime and resolving unequal energy consumption in WSN. We demonstrate energy transfer for practical decoupling using low-cost and low-footprint, laser -power beaming that powers current WSN platforms at 100 m of range. We design and implement LAMP, a tiered architecture to manage energy supply to both mesh and clustered WSN deployments using an energy distribution protocol. We evaluate our system to show that, for an additional cost of $29 per mote, LAMP can support perpetual mesh functionality for up to 40 sensors or 120 nodes in clustered operation.

“…The deployment of WSN for real-time applications is hindered because of the limited energy backup of the sensor [5]. The energy backup can be enriched by attaching renewable energy sources with the sensor nodes, which improves the IAN lifetime [6]. The power consumed by the sensor node to establish the transmission may get changed based on the distance between the sensor node and base station.…”

Original scientific paperThe main function of industrial automation networks (IANs) is to monitor and control processes. In general, the sensor nodes utilize batteries as an energy source to control processes. The clustered IAN aims at maximizing the lifetime of the sensor node by improving the energy efficiency. The proposed system is targeted for utilization of the long distance wireless transmission radio modules where the energy distribution needs to be reduced to a greater extent. This paper presents the impact of adopting sleeping mechanisms in transmitting a physical variable from the industrial area to the base station where the controller is present. The number of transmissions that occurs due to the application of aggressive sleeping behaviour has been compared to the normal sleeping behavioural approach. The energy spent by the network for communication greatly depends on the number of transmissions. Hence, the network lifetime can be maximized by minimizing the energy spent for transmission. Keywords: energy efficiency; industrial automation; routers; sensors; WSN; ZigBee Maksimizacija duljine i trajanja klasterirane mreže industrijske automatizacijeIzvorni znanstveni članak Osnovna funkcija mreža industrijske automatizacije -IANs (Industrial Automation Networks) je nadzor i upravljanje procesima. Općenito, čvorovi senzora koriste baterije kao izvor energije za upravljanje procesima. Svrha je klasteriranog IAN-a maksimiziranje vijeka trajanja senzorskog čvora poboljšanjem energetske učinkovitosti. Predloženi je sustav namijenjen primjeni radio modula s bežičnim prijenosom na daljinu gdje se razvođenje energije treba znatno smanjiti. U radu se daje prikaz djelovanja primjene prikrivenih (spavajućih) mehanizama u prijenosu fizičke varijable iz industrujskog područja u baznu stanicu gdje postoji regulator. Broj prijenosa zbog primjene agresivnog prikrivenog ponašanja uspoređen je s pristupom uobičajenom prikrivenom ponašanju (sleeping behavioral approach). Energija koju troši komunikacijska mreža uvelike ovisi o broju prijenosa. Prema tome se vijek trajanja mreže može maksimalno produžiti minimiziranjem energije potrošene za prijenos.
