SL-BUS Technology

IoT Applications Framework for Smart Devices

Introduction

India is an emerging economy with huge projected growth, the number of electrical/electronic appliances and consumers are growing rapidly leading increased demand for more power requirement. On the other hand, knowing the fact of having limited sources of power generation,conservation of energy is the best approach to solve this problem. Smart Lighting is a real need for India and SL-BUS Technology solution offers innovative, modular unique and affordable method to solve this problem smartly. SL-BUS Technology uses Marvell's IoT product and is designed to ensure energy efficiency, and include automated control and configuration (local as well as remotely through cloud infrastructure). Smart data driven algorithms leads to automated and manual controls that adds more value to the solution. Example- occupancy, usage history, etc. ensuring lower energy usage and high cost savings.

Technologies available and their competitive analysis

The Smart Lighting mainly emphasis on energy efficiency and technologies are evolving in all possible directions to support this objective that includes Photonics, Optics, Power, Energy, Control and Cost. We are going to focus on technologies useful for futuristic Smart Lighting Control Systems. Lighting control systems evolved for a specific need and the technologies are evolved around available options in that specific time eras. In the early days Analog (0-10V, AMC192, D54) mostly unidirectional protocols evolved for purely control use cases. Then Digital (DSI, DALI, DMX, KNX) evolved as digital transformation of older analog technologies and then further get evolved for data exchanges (bidirectional). These technologies are mainly evolved to provide more and more sophisticated control systems with events, actuators for control, status reporting and configuration. Mostly the communication backbone is wired connectivity for these technologies. In parallel Building Management Systems (BMS) evolved to manage bigger installations through centralized control using these lighting connectivity technologies. Further technological enhancement in the wireless domain added few more to the list (X10, Zigbee, Z-wave, Bluetooth, WiFi, LoRa, M-Bus and so on). Wireless offers flexibility to bring in more and more devices to the smart lighting control automation. Today, evolution of internet, smart phones and M2M communication added one more dimension to the control systems i.e. communication amongst devices over internet i.e IoT. Early Nest Thermostat, Brillo-Weave from Google, HomeKit from Apple are latest advancements to address the lighting control through internet using smart devices. Different silicon vendors (Marvell, TI, Broadcom, Mediatek, etc.) are geared up with their System on Chip products (SoCs) to enable with backbone connectivity solutions.

Challenges for Smart Lighting Control systems in India

There are several technologies available in the market to address Smart Lighting control needs. Architects, Lighting Experts and Product Companies are using them since last few decades (mostly importing). Overall market penetration is not that high because of factors like demand, cost, support, expertise, awareness, education and more important perfect fit for the requirements. Interoperability: This is another big challenge that is being faced in the smart lighting control products. There are several products available in the market but they work independently, few of them provide family of product that can interoperates but mostly follows proprietary protocols. There are certain products and technologies that interoperate across different vendors but are not affordable. Availability and affordability: Most of the products in this segment are imported and that adds higher lead time and cost to the end product, also the pre and post sale support model for such products is very limited and expensive. Lack of Local Manufacturing and Support: Mostly local lighting product companies are focused on the key product requirement and their development is mostly around it. Most of them are not equipped to adopt and develop advanced lighting control systems in their products due to lack of adequate support from technology providers.

University Programs (SL-BUS Technology Education)

Core objective is – To create a pool of developers to address growing market demands. We believe that in any technology evolves more rapidly when more and more number of brains works on it. Linux is the best example, we believe in open source philosophy. Sharing knowledge is the best way to achieve success and Educating people is the only way to achieve that. VADACTRO works with customers, installers, developers and students in all stages to take this technology to the new horizon. There is separate initiative VADACTRO Education (www.vdedu.vadactro.org.in ) through which this technology is planned to spread out into educational systems in the Universities. In fact VADACTRO has already started IoT-EvalKiT program for students that includes WiFi MCU board, Debugger, SDK and Documentation.
