Internet of things

1¡¢ Application of water, electricity and gas meter system of Internet of things

When the "Internet of things" is only a concept in people's minds, 20000 residents in Huairou have enjoyed the convenient life brought by the Internet of things. Yesterday, the reporter personally experienced the intelligent meter reading function of the Internet of things in Huairou.

On the morning of April 27, at the home of a resident in building 3, Xingfu Dongyuan community, Huairou District, the hostess Jiao Guirong held the child in one hand and sent text messages with her mobile phone to "open the valve", "close the valve" and "recharge" the water meter at home. "You see, if I send a text message 'KF' to my water meter number, the water valve will open. If I send 'CX', I can check the water meter in a few seconds, know how much water is left, and recharge the water meter at any time." Jiao Guirong said that in the past, when it was time to copy the water meter every month, people had to stay at home and wait for the staff of the water supply company. Now it can be done by sending a text message anytime and anywhere.

It is understood that Jiao Guirong's home is the Internet of things water, electricity and gas meter system independently developed by Juying electronic enterprise. At present, 20000 households in Huairou District have replaced the system for free, which can allow "busy people" thousands of miles away to operate water and electricity in the housekeeper, and also facilitate the managers of gas or water companies to read meters remotely.

"As soon as you log in to the system, you can check the usage of each user." Peng mingshuang, the person in charge of the enterprise, said that in addition to the advantages of convenience, quickness and intelligence, the meter of the intelligent meter reading system will also form an information cloud of the collected user basic information. On this basis, cloud computing can provide information support for the government when making decisions on water saving, electricity and gas prices.

2¡¢ Heavily funded 9 Internet of things application projects

Some application projects closely related to life will also be included in the scope of funding, including Internet of things health management, air and water quality monitoring, community coverage Home smart home system, etc.

3¡¢ Gansu digital technology into greenhouse farmers send text messages to grow land

"The temperature exceeds the predetermined temperature." Li Shilong in Zhangma village, Xuebai Township, Minqin County, Gansu Province installed two digital greenhouses. After receiving this message, he replied to the message "open the air outlet." The air outlet of the greenhouse opens automatically. After a while, the temperature in the shed drops automatically.

Referring to the "mobile greenhouse housekeeper" dressed on the top of the greenhouse, Li Shilong explained that this sensor can sense and transmit various environmental indicators such as temperature, humidity and illumination in the greenhouse. As long as the predetermined temperature and humidity are exceeded, the sensor will automatically send a text message reminder to the shed owner's mobile phone. "Even if I'm out of town, I can control the greenhouse as long as I send a text message."

"This kind of greenhouse has many advantages." Li Shilong introduced that the "greenhouse housekeeper" can also realize the remote diagnosis of crop diseases. As long as the camera installed in the greenhouse is used to take photos of sick crops, and then the photos are transmitted to the national agricultural benefit information platform, domestic agricultural experts will consult and give treatment methods.

The Internet of things technology, which once "caught fire" at the Shanghai World Expo, has now entered farmers' homes.

Wang Shuping, a farmer in Neiguan village, neiguanying Town, Anding District, Dingxi City, Gansu Province, who has just returned from "talking about business" in Guangdong, has 30 vegetable greenhouses at home, which have been refitted into digital greenhouses by China Mobile Gansu company this year. "Now you can control the automatic lifting of the shed roller shutter by sending a text message, and you can also control the temperature, humidity and carbon dioxide content in the shed at any time."

Originally, Gansu Mobile 12582 information platform and agricultural science and technology experts in Gansu and Beijing established a "relationship network". Combined with the seasons of agricultural production and the needs of farmers, experts prepared information and sent it to farmers through this agricultural information and communication platform. Experts can directly serve farmers, and farmers can also directly "consult" with experts face to face.

It is reported that Gansu Mobile has also recruited more than 400 rural brokers in 14 cities, prefectures and townships in the province. For farmers who do not subscribe to 12582 SMS, the rural broker sends the supply information to the nongxintong platform. The platform matches the information nationwide to help farmers find the most appropriate sales and purchase information, and then these sales information is transmitted to farmers through rural brokers.

According to the analysis of insiders, allowing digital technology to enter the greenhouse and the countryside has not only changed the traditional farming method facing the Loess and back to the sky, ended the history of relying on heaven, but also changed the traditional way of thinking of farmers and led them into a new digital world.
