In May 1988, Yan Bing transferred from the army to Jiaxing Armed Police Hospital, where he was responsible for the maintenance of the hospital's electronic equipment and network communication devices.
Because of his excellent hardware maintenance skills, the Pinghu Municipal Public Security Bureau, which was short of talent in this area, recruited him in 2000, so Yan Bing came to Pinghu. "Electronic and electrical equipment is updated quickly, so I have to pay attention to improving my technical level every day so that I can solve all kinds of 'difficult problems' in a timely manner." As Yan Bing said, because the Public Security Bureau of monitoring equipment hardware and network equipment, etc. is not only quite a lot, but also very complicated, so the first few years, he almost every day to spend half a day to read the electronic information newspaper, through repeated practice operation to improve their business level, to ensure that every day can be in the shortest possible time to solve the problem, to ensure that the public security of electronic communication and network smooth. His name is Yan Bing, 38 years old, Pinghu City Public Security Bureau employees.
Yan Bing's striking is that he tinkered with a "home power plant" - solar power generation device, he installed 16 solar panels on the roof of his home, through the absorption of solar power, the use of battery boosting, inverter conversion to AC power, the highest output power up to 800 watts. In addition to the air conditioner and refrigerator, the rest of the house, such as fans, computers, stereos, televisions, lights, etc., are all self-generated power supply.
Yan Bing said, if the battery is full of electricity, even if the power outage for two weeks or half a month of rainy weather, the home of the basic life of electricity can still meet. Because these two "even" are almost impossible to happen, so his family does not lack of electricity throughout the year. Since the set of solar power generation device, the Yan family never worry about electricity, but rather for the excess power and worry - in order to extend the service life of the battery in winter, had to light up several lights 24 hours a day to make the discharge process. Yan Bing on the solar power generation device research began in the early 1990s, when he lived in Pinghu suburb of Danghu District, due to power supply constraints, often be pulled to limit power, life is very inconvenient. Yan Bing put his sights on solar power: if the family also engage in such a set of devices, not to save money and worry? But he soon found that the market to buy ready-made solar power equipment, the price is very expensive, to recover the cost of an unknown to the monkey years and months. Yan Bing has been a soldier, in the army to engage in communications maintenance, on the electrical aspects of the love, suffering from the lack of electricity, he began to peck and grind homemade power generation equipment.
With the help of friends, Yan Bing in Shandong, Gansu, Beijing, Xinjiang and other places to collect solar power generation equipment parts, whether it is broken monocrystalline silicon panels, or scrapped batteries, he was a baby general procurement back, and then according to the usual learning to repair and assembly, turning waste into treasure. Six months later, the solar power generation device was successfully developed, Yan Bing installed 2 groups of 4 panels at home, happy to enjoy the sun to provide the "free electricity meal". After moving into a new home in June 2003, Yan's house area of 178 square meters, household appliances are also complete, the original power generation device has been unable to meet the demand, he began to consider "expanding the scale". In order to achieve the best power generation results, he flipped through a bunch of self-subscribed electronic magazines "charge", but also often with the roadside solar-powered street lamps "entangled", and finally ten years ago on the basis of the prototype of the assembly of a set of homemade power generation device improved version, including 8 groups of 16 solar panels and an inverter with an output power of 800W.
Of course, the homemade generator is also a risky move, if the safety measures are not in place will bring "disaster" to the family. Yan Bing knows this well and has taken careful safety measures. In order to prevent "cross-power supply", he installed a completely disconnectable bidirectional gate knife at the connection of two sets of lines for solar power supply and net power supply; in order to avoid overheating of circuits in case of accidents, he installed a thermostat in the attic distribution room, and the inverter will automatically jump off when the temperature reaches 75℃. In addition, he also purchased three portable fire extinguishers in case of accidents. The comment given by the power expert on the site survey is: absolutely safe. East China in recent years, often "power shortage", last year, the peak season when Yan Bing's Star Island Sunshine District to pull the power limit twice a week, the residents can not stand the pain of the heat, they have to run to the outdoor cool, dark at night had to light candles for lighting. Yan Bing's family is leisurely and steady sitting in a fishing boat, indoor living room 500W lighting so that his home at night is as bright as day, electric fans tirelessly clamor to send the wind. His son's classmates heard of such a good thing, after school all ran to his home "cool".
The solar power generation device put into use, the economic benefits are very obvious. The other residents of the Sunshine District, the monthly power supply fees are in one hundred and sixty-seven yuan, he received a notice of payment on the amount of money shown on the level has remained stable at about 30 yuan. And he spent the cost is not high: the same area of a battery plate, the market price of 500 yuan, he only used thirty or forty dollars to get it done; the same specifications of the inverter sold on the market to 1,500 yuan, he only spent less than 300 yuan; the whole set of equipment investment is only more than 3,000 yuan. Yan Bing's invention alarmed Jiaxing, Pinghu two levels of power sector experts, they joked that if everyone like Yan Bing, the country in addition to a few large power plants, small power plants have to close down. With this invention, Yan family gradually lively. Previously crowded, is the son of his classmates over the "cool", neighbors to see rare; now more people, more Department of the visit to learn. Some keen on solar energy development of the same people have come to ask for advice, Jiangsu Wujiang, Hangzhou Fuyang, Huzhou, Haining and other places of the manufacturers come to learn from the experience. There are even a class of "talent scout" door to door, promising to pay a lot of money, want to ask him to go out. In this regard, Yan Bing always smiled and shook his head: business exchanges on the discussion is possible, but I want to leave my favorite public security team can not do.
Yan Bing has an idea, the city is now engaged in street monitoring construction, but the cost is huge, Pinghu this year, the installation of 33 probes, only the point of deployment, the electricity spent 330,000 yuan, the future will have to pay the electricity bill. He is considering how to engage in solar power generation device instead, this move if successful, can save hundreds of thousands of dollars for the unit, and an investment in a lifetime benefit, the future also do not have to spend money on electricity.
