Gate remote control system, tap 10,000 acres of fertile fields with your fingertips to drink full of water

🌾 The “hard life” of the old gate worker

“Shake the gate? That's a trick to delaminate the skin! "Master Li, an old gate worker in the Yellow River Irrigation Area, stretched out his calloused hand. He remembered rushing to irrigate on a winter night twenty years ago: wrapped in a torn padded jacket, he stepped on the frozen embankment with one foot deep and one foot shallow. With a semi-cold bun in his arms, he turned more than 30 gate handwheels one by one. His hands froze and he stuffed them into his arms to cover them, and if he didn't pay attention, he would slide into the biting water.

These scenes are engraved in the bones of the old water conservancy people：
– Time black hole: Three thousand acres of land release secondary water, busy from dark to dawn
– Safety hangs in the air: Those who broke their legs on the night patrol, and those who fell into the water without a roof, they have it every year.
– Water is more expensive than oil: Closing the gate slowly for half a beat, the white water overflowed the ridge of the field, and the old farmer squatted on the ground to wipe away tears.

The old secretary of Jingtai River in Gansu pinched his finger and calculated that the water leaking from the artificial control gate can fill 2,000 standard swimming pools a year.

Mobile phone has become a new knife

The change began with a group of ”obedient" iron guys. Beside the rice field in Sheyang, Jiangsu, technician Xiao Chen smiled and took out his mobile phone. With the flick of a finger on the screen, the steel gate a hundred meters away “clicked” and lifted, and the clear stream poured into the Yangtian singing happily.

“Look at this iron box! "Xiao Chen patted Tian Tou's control cabinet：
– Solar panelChasing the sun like a sunflower
– Electric push rodBecame the “iron arm” of the gate
– Water level probeMore sharp-eyed than the old style-automatically stop when the water is full

The Jingdian Irrigation Area of Gansu is more slippery. The engineer installed a “brain" on the gate: how much water comes upstream and how much water is required downstream, the system can figure it out by itself. Just like there is an invisible water plumber, the utilization rate of dry canals has suddenly increased by 1%, and the water saved in one year is enough to irrigate 30,000 mu of wheat fields!

🌟Four visible benefits

Save time and effort like a trick
“In the past, releasing water was like fighting, but now I drink tea and look at the screen. "Captain Liu of Linhai Farm has a comparison photo on his mobile phone: in the past, there were always three or four people shaking their handles by the gate, but now the wolfberry in his thermos cup is stretching.

Dripping water into gold, saving a lot of money
The smart gate has become a "stingy expert”-the channels in Huantai, Shandong, no longer run dripping, and the water saved can pour 400 more acres of orchards. Lao Zhang, the water plumber, patted the control box and said, "The water bills saved by this iron guy in two years are enough to install street lights in the village!“ ”

There is no shortage of security guards
The 22-hole gate of Tongji Weir in Zhejiang has been transformed into a ”good student". Xiao Wu, the duty officer, called up the monitoring: "Look! It is clear how high each door opens and how much to eat. If there is an abnormality, call the police immediately, and you don't have to climb the gate tremblingly anymore. ”

Drought and flood protection is emboldened
During the flood season last year, Fuhe, Jiangxi Province, called the police in the middle of the night. Lao Yang, who was on duty, was awakened by his mobile phone, opened the APP and tapped it three times, and the spillway 20 miles away was automatically raised. He recalled with a smile: "Then go back to sleep, and solve the danger by yourself! ”

The future is sprouting on the ridge of the field

The 5G gate of the Sheyang Test field can already "eat hundreds of meals”-solar energy and MAINS electricity can be switched at will. Jingtai River's new system learns to “watch the sky and eat": the rainstorm warning has not yet arrived, and the gate has been raised half a foot in advance.

Mobile phones have become new agricultural tools, The old masters are also catching up with the fashion. Ma Daye in the Yellow River Irrigation District had just learned to use the APP. He proudly showed the record of watering the ground: “My son said that this curve is more beautiful than the stock trend!" ”

When the morning light shines on the automatically closed floodgates, and when the data streams meet quietly in the clouds, thousands of years of farming are undergoing a gentle revolution. Those mud-stained sword blades lay quietly in the museum, and new hope was gurgling to a richer field at the touch of every fingertip.
