The 77-year-old "old expert" Hua Jiading has successfully designed the first domestic radio and audio conferencing dispatching switchboard, and was also hired as a national device quality appraisal reviewer. Before retiring, he worked as an engineer in a well-known electronic instrument company in China. After retiring, 10 years ago, he found that the lighting system resources of large and medium-sized enterprises were very wasteful. At the same time, the country began to vigorously promote energy-saving products, and he decided to invest in the “public lighting energy-saving reform implementation plan and product compositionâ€. In research and development.
The public lighting energy-saving reform implementation plan and component products that have been authorized by the national patent have been developed and designed since 2000, and have been modified and template tested until the prototype is made. The centralized control system is the core technology of this technical solution, which can automatically set the lighting time and convert the lighting working state. Illumination can be freely selected according to three modes of operation: remote control, automatic and manual. Both the line and the luminaire can be freely converted to illumination over different time periods. For example, taking the group unit as an example, between 6pm and 10pm, the connected lamps are brilliant lighting, that is, all the lights are bright; between 10pm and 12pm, the connected lamps are automatically turned into bright lighting, that is, half of the lights are bright; After 12 o'clock in the night, it will automatically turn into energy-saving lighting. When people turn on the light, the delay will be turned off in 1 minute. After dawn, the full lighting line will be automatically turned off, saving a lot of power and electricity. The operation has both controllability and can be optionally used in three operation methods: manual operation, infrared control, and program control, which is conducive to energy saving.
The centralized control system mainly adopts the centralized control, three-wire transmission, and terminal transformation technology schemes to change the power supply mode of the outdoor public lighting line transmission and access lamps, so that the connected lines and lighting fixtures can be in the state of brilliant illumination, bright illumination and energy-saving illumination. Arbitrary conversion, breaking the traditional pattern of lighting lines and lighting only exists in one way of lighting. The technical solution includes a lighting energy-saving control system, a remote-controlled public lighting energy-saving converter, a hand-controlled public lighting energy-saving converter, a touch-type energy-saving switch with a long-term function, and an acousto-optic-controlled energy-saving switch with a long-term function. 6 technical achievements such as the infrared inductive energy-saving switch with long-term function. The energy-saving facilities that are currently widely used on a public lighting line with only a single lighting working state, that is, the "on" and "off" states, are improved to have energy-saving facilities that are controllable and have two convertible lighting working states. .
Hua Jiading said that the technical solution is an energy-saving method after the general update of energy-saving lamps. After many times of scale test, after installing the energy-saving system, compared with traditional public lighting, the effect of saving electricity and saving is obvious. For example, at a commercial electricity price of 1.2 yuan / KW / daily electricity consumption with 12 hours / annual power saving section count, public lighting uses 500 incandescent lamps, about 165,000 KW energy savings, electricity costs 192,500 yuan; The use of 500 energy-saving lamps will save energy of 80,000 KW and electricity costs of 95,000 yuan. If the country is promoted, according to the test, the annual electricity and energy consumption is twice that of traditional lighting facilities.
In addition to saving energy and electricity costs, the technical solution is put into application to improve the safety value of energy-saving lighting lines, installing energy-saving lighting lines and energy-saving lamps used in communities, streets, buildings, and changing from energy-saving lighting state to long-lighting in the event of an emergency. Lighting status, to ensure community social security and the safety of people's lives. According to the old expert, "According to my calculation, using this patent, a company with 250 street lamps will save about half of the street lamp electricity costs every year, and the one-time investment costs can be fully recovered in the same year." The experiment proves that the same line It is feasible to freely convert two kinds of lighting working conditions on the road, and also accelerate the development and popularization of street lights intelligently. According to the report statistics, street lamps in the world consume a lot of energy, and lighting accounts for 6% of total greenhouse gas emissions. To this end, various industrial countries have invested a lot of manpower and financial resources to study the technology and application of intelligent street lamps.
It is reported that so far, there is no institution in the country to explore, develop and develop outdoor lighting similar technology products including intelligent street lamps. More details into the patent world network to understand.
postscript:
<br> <br> imminent reform of public lighting street lamps consume energy in 2009 alone, the Los Angeles spent $ 15 million on the street, the 11.01 million tons of carbon emissions. In order to achieve the carbon balance index, many countries, especially some developed countries and regions, are now thinking of ways to make street lighting more intelligent and more effective, and invest a lot of manpower and financial resources to study the technology and application of intelligent street lamps. According to authoritative media reports, it is expected to popularize intelligent street lamps in Copenhagen soon.
In Denmark, the newly developed intelligent street lamp scheme has the same effect as China's “public lighting energy conservation reform implementation plan and component productsâ€, but it is slightly insufficient in terms of function, use and use method. For example, the energy-saving lighting line of the community can be full-length in the event of an emergency, and the function of switching to the energy-saving state at any time is what they do not have; in the line transmission operation, the technical solutions of remote control and second-line transmission are compared with the public. The lighting energy-saving reform implementation plan and the three-wire transmission and terminal control of the constituent products have resulted in them being unable to freely change different lighting working states on one line at the same time.
The implementation plan and composition of public lighting energy-saving reforms have been developed since 2000. After several years of continuous research and repeated demonstrations, technical indicators have reached the international advanced level. At present, the maturity of the technical solution has been sampled, and through the small test, it can be said that the first step has been taken on the road of industrialization development.
At home and abroad, the inventor Hua Jiading first proposed the same transmission line, there may be two methods of conveying the working state of illumination. Experiments show that this method is not only feasible, but also accelerates the development and popularization of street lights. Because the technical scheme reforms the operation mode of public lighting facilities, the transmission line is upgraded from the currently used single lighting working state, that is, the "on" and "off" states to the simultaneous existence of two freely convertible lighting working states. , that is, energy-saving lighting and long-light lighting status. It has achieved the purpose of scientifically distributing electric energy, fully utilizing sufficient light energy, ensuring social security and eliminating electric energy waste. It can greatly promote the construction and development of low-carbon economy and energy reduction.
Impression flowers Ka Ting: sunset red as fire science and technology writing life <br> <br> eighth in last year's China International Invention Exhibition, you would not imagine, 77-year-old expert can spend Ka Ting "ringleader, The second place and the flower-seeking are all under the hood! However, the old man has really created a miracle. With excellent technical strength, we won one gold, silver and bronze medals. Among them, the electrical control box update series technology took the silver award, with a voice alarm function, the anti-theft suitcase took back the bronze medal. After retirement, the old expert Huajia is determined to be a veteran new warrior in his own invented career. He has invested in research and development and has a passion for work. It can be said that almost all of my leisure time was given to the invention.
Samples have been available, and the small series of electrical control box update series (200910024492.7) and the suitcase with voice alarm function and anti-theft (patent number ZL201220410640.6) are very promising. The technical achievements of the electrical control box update series can improve the safety of transmission and reduce labor risks through infrared control and control of the process. It can be installed in different places to achieve office automation. In terms of work flexibility, it can serve both the first line and the advanced equipment.
With a voice alarm function, the anti-theft suitcase is a masterpiece of old experts paying attention to the lives of the people. In the past few years, he discovered the phenomenon of theft in the market. He felt that he should develop the technology by considering the invention for the safety of people's property. The characteristics of the old experts' research and development are innovations. It is also very obvious in this technology. For example, the technology has functions such as voice call, sound and light alarm, anti-theft and anti-theft. In the past, similar technology products are rare. The old expert said that the original anti-theft and anti-theft functions have not changed. When you are stolen, you can directly call the voice alarm function of “grabbing the thiefâ€, especially for the female users to show the alarm effect. Don’t underestimate this. Small ideas, it may give the violent implementers a sense of sorrow and panic!
The sunset is red and the fire is written, and science and technology writes about life. This is the portrayal of the life of the old experts. I hope he will go all the way!
