Technical field: This technology belongs to the field of automation technology.
The research in this project has gradually deepened from electrical instruments to system integration. The developed products meet the practical requirements of electrical fires and the commercialized residual current electrical fire monitoring devices and systems have achieved the following technological innovation results:
Main technological innovation contents and characteristics:
1. The first IoT technology to apply multi-meter-in-one technology on smart grid terminals
It highly integrates the three major functions of fire monitoring, power distribution monitoring, and energy measurement into one technology, achieving the effect of integrating multiple meters and using multiple meters.
2. Innovative use of temperature sensing technology for intelligent residual current control
In the 0.4kV low-voltage distribution system, the generation of electrical fire hazards such as residual current and temperature in TN-C-S, TN-S and local TT systems is detected. The number of temperature and residual current monitoring channels can be flexibly configured to maximize the requirements of on-site installation.
It can realize signal acquisition of three-phase voltage, three-phase current, residual current and temperature, and can also convert the signal acquisition circuit of three-phase voltage or three-phase current into a signal acquisition circuit of business current or temperature to realize multi-loop fire monitoring., flexible function transformation. The device is small in size and simple in appearance. It still maintains a small size while realizing all functions, making it very convenient to install and view.
3. Develop dual communication technology for electrical fire devices
It can simultaneously realize online communication with the fire protection system and power monitoring system or other upper computers. Using field bus communication technology, the upper computer management software can always monitor the operation of the site and discover alarm information in a timely manner.
4. Self-developed electrical fire monitoring system
It has functions such as real-time data acquisition and processing, graphical interface display, event alarm and recording, setting and modification of fixed values, statistical reports and printing, etc., and can realize alarm, monitoring, control and management of protected electrical lines.
Through innovation, this project has obtained 9 authorized utility model patents, 4 appearance patents, accepted 1 invention patent (201110427791.2), 1 utility model patent, 4 software copyrights, 2 works registrations, participated in the drafting of 3 national standards, published 5 papers in core journals and 2 monographs.
The ARCM series products developed through industrial application of this technology are used in the temporary power distribution center for the opening/closing ceremonies of the 2010 Guangzhou Asian Games. The developed Acrel-6000 residual current fire monitoring system has been used in Kunming Changshui International Airport and Tianshui First Major projects such as the First People's Hospital, Shanghai Chenjia Town Binjiang Ecological International Community and other major projects have a strong influence and demonstration role, making the project products have a high reputation and reputation in the market. The brand image of Ankeri was quickly improved. In 2012, the annual output value was 26.94 million yuan and the profit was 5.21 million yuan, achieving significant economic benefits.
