This paper mainly talks about the design of a controlling and monitoring system of the robot arm based on FPGA. The robot arm has 6 DOFs (Degree of Freedom). Every joint was driven by a servo motor. These servo motors were located as the finger, the wrist, the three arms and a rotatable platform. The FPGA programs were completed using the Verilog HDL. We programmed a LabVIEW VI to function as a controlling center. The data between PC and FPGA were transported through a ZigBee wireless network which consisted of 2 XBee devices and a wireless camera. They were used to monitor the moving condition of the arms. The experimental results show that the robot arms move with no apparent delay controlled by the host computer. The real-time display of the arm’s status is realized by the upper computer.

Lighting Energy

PLC (programmable logic controller)-based street lighting energy-saving and remote monitoring system is designed to improve energy-saving technology and management level. The designed illumination economizer contains PLC-based controller unit and compensating transformer unit, which can realize closed-loop voltage control at the stage of voltage stabilization, and reduce the negative influence of power line voltage fluctuation upon lamp service life and visual luminance. On the basis of the illumination economizer, a GPRS-based street light remote monitoring and control system is designed with configuration software. The whole system has been operating reliably in Harbin, China for many years with an over 50% energy-saving rate, decreasing the illumination management cost and promoting the intelligent management level.

And Control

To realize the efficient and stable real-time monitoring and intelligent management of the urban public lighting, the remote monitoring system is developed. The system is composed of monitoring center and monitoring terminals, and realizes network connection via the advanced remote wireless communication technology GPRS. It uses TI Company’s MSP430 processor chip as the monitoring terminal controller, which integrates automatic control, data acquisition, communication and other technologies and has such functions as monitoring, remote control, anti-electricity theft, remote meter reading and communication. It’s proved by practice that the designed controller features reliable running, sound real-time performance and low cost, and has a broad and bright application prospect. The monitoring and management of public lighting is a typical sector and important part of the civil work. Due to the continuous development of urban construction and ever-enlarging lighting coverage, the traditional lighting management methods can not realize centralized monitoring, have poor real-time performance and cost lots of human and material resources; thus, can not satisfy the requirements of energy saving and efficiency improvement[1]. GPRS (General Packet Radio Service), the wireless packet exchange technology based on the second generation mobile communication system GSM, is very suitable for transmitting non-continuous, unexpected and small sets of street lamp monitoring data. Also, quick & easy log-on, real-time online, high-speed transmission, sound economical efficiency and many other advantages make GPRS become the first choice for remote measurement and control system[2]. Therefore, the development of GPRS-based public lighting remote monitoring system becomes a necessity. The designed monitoring system in this article is a typical distributed monitoring and data acquisition system integrating computer technologies, modern communication technologies and automatic control technologies. It conducts centralized monitoring and control on the cabinet transformer substations, transformer cabinets, control cabinets and other slave monitoring systems of the public lighting such as street lamps and landscape lamps of the city, to realize the real-time, remote monitoring and intelligent management of public lighting and ensure the efficient, all-weather running and on-demand, energy-saving lighting.
