1 Design and Construction of Microcontroller Based Wireless Remote Controlled Industrial Electrical Appliances Using ZigBee Technology 1,2 Lu Mai1, Min Zaw Oo2 Department of Electronic Engineering, Mandalay Technological University, Mandalay ABSTRACT Industrial automations which are mostly depend upon the power systems & which requires distance controlled and regulated systems. Wireless technology which meets to cost, speed and distance will always be a point of an interest for research. This research proposes microcontroller based wireless remote controlled for electric systems parameters like voltage and current using ZigBee technology. PIC16F877A controller is used in a predominant way because it is rich in peripherals and hence many devices can be interfaced at ease, it is also very cheap and can be easily assembled and programmed. The PIC controller controls the devices and sends the sensor values to the PC via ZigBee module. Although Bluetooth is better than ZigBee for transmission rate, ZigBee has lower power consumption. Hence, ZigBee is generally used for 24 hours monitoring of communication transmission systems. Its main feature is its use of the ZigBee protocol as the communication medium between the transmitter and receiver modules. It illustrates that the new ZigBee standard performs well industrial environments. Keywords Microcontroller; wireless control network; ZigBee. I. INTRODUCTION The goal of the paper is to achieve intelligent device control and secure environmental working conditions by interfacing various sensors and devices to the PIC16F877A microcontroller and ZigBee modules with the PIC controller for data transmission respectively. Wireless based industrial automation is a prime concern in our day-to-day life. Industrial automations depend on the power systems and which requires distance control and regulated systems. Wireless Control Networks (WCNs) have revolutionized the design of emerging embedded systems and triggered a new set of potential applications. In addition to building automation, environmental surveillance, or military operations Industrial automation is also expected to greatly benefit from WSNs in terms of faster installation and maintenance, cost savings, and easier plant reconfiguration. ZigBee is an emerging short-range, lowrate wireless network technology. ZigBee also presents some potentially interesting features for supporting large-scale ubiquitous computing applications, namely power-efficiency, timeliness and scalability. In managing the move to wireless, it is clear that common wireless protocols such as Wi-Fi and Bluetooth can be utilized on the factory floor. The challenge is to understand how to utilize wireless solutions, developed for IT applications, as replacements for wired systems in time-critical scenarios typical of factory floor domains. To date, most wireless systems in production systems are focused on applications that require polling frequencies on the order of seconds or longer. Standardization of technology again plays an important role for globalization of these profile developments. ZigBee due to its standardize operational and network management properties will be suitable wireless interface technique, ZigBee also have low data rates over a middle distance and AES encryption properties which are again guaranteed for required communication system. II. MICROCONTROLLER An Embedded system is a combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a specific function. Embedded systems are usually a part of larger, complex system. Dedicated applications, designed to execute specific activities, are implemented and embedded in systems. These embedded applications are required to collaborate with the other components of an enclosed system. Embedded application components 79

2 interact mostly with the non-human external environment. They continuously collect data from sensors or other computer components and process data within real-time constraints. Microcontrollers are "embedded" inside some other device (often a consumer product) so that they can control the features or actions of the product. Another name for a microcontroller, therefore, is "embedded controller." Microcontrollers are dedicated to one task and run one specific program. The program is stored in ROM and generally does not change. They are often low-power devices PIC Microcontroller There are a wide variety of microcontrollers available to implement various tasks, among them the 8051 and PIC are the mostly used. The 8051 is probably the most popular 8-bit microcontrollers ever. Many different I/O features are integrated around the 8051 core to create a microcontroller which needs only very little extra hardware to do most of the jobs. The main disadvantage of the standard 8051 core is that there's only one 16 bit pointer register available. Moving a block of data is a very tedious job which takes far too much data moving overhead. It also does not have an internal Analog to Digital Converter (ADC). PIC16F877A is an 8-bit microcontroller which has 40 pin DIP and is based on Harvard Architecture. PIC stands for Peripheral Interface Controller and F for flash memory. The PIC16F877A features 256 bytes of EEPROM data memory, selfprogramming, an LCD, 2 Comparators, 8 channels of 10-bit Analogue -to-digital converter, 2 capture/compare/pwm functions, the synchronous serial port can be configured as either 3-wire Serial Peripheral Interface for the 2-wire Inter-Integrated Circuit bus and a Universal Asynchronous Receiver Transmitter. All of these features make it ideal for more advanced level A/D applications in automotive, industrial, appliances and consumer applications. So we have utilized the MICROCHIP PIC16F877A microcontroller in the project. III. specification was finalized in December 2004, and products supporting the ZigBee standard are just now beginning to enter the market. ZigBee is designed as a low-cost, low power, low-data rate wireless mesh technology. The ZigBee specification identifies three kinds of devices that incorporate ZigBee radios, with all three found in a typical ZigBee Network Topology for ZigBee The ZigBee network layer (NWK) supports star, tree, and mesh topologies. In a star topology, the network is controlled by one single device called the ZigBee coordinator. The ZigBee coordinator is responsible for initiating and maintaining the devices on the network. All other devices, known as end devices, directly communicate with the ZigBee coordinator. In mesh and tree topologies, the ZigBee coordinator is responsible for starting the network and for choosing certain key network parameters, but the network may be extended through the use of ZigBee routers. In tree networks, routers move data and control messages through the network using a hierarchical routing strategy. Tree networks may employ beacon-oriented communication as described in the IEEE specification. Mesh networks allow full peer-to-peer communication. ZigBee routers in mesh networks do not currently emit regular IEEE beacons. This specification describes only intra-pan networks, that is, networks in which communications begin and terminate within the same network. ABOUT ZIGBEE Fig. 1.
