Take the Tower Crane control room“ Please ”To the ground
（Newspaper reporter Guo Jun）February 28，Shaanxi Construction Machinery Co., Ltd., affiliated to Shaanxi Coal Group, Gaoling District, Xi'an City（Hereinafter referred to as Shaanxi Construction Machinery Co., Ltd）Industrial Park Tower Crane Delivery Square，The 50-meter-tall Tower Crane stretches out its long boom.，Lifting material back and forth。“After the Spring Festival，Our company started work early.，Tower crane shipments have also become busier.。”Tower crane driver Zhou Xianchun said.。
It is different from ordinary construction sites.，The tower crane driver is not sitting in the cab.，Instead, he sat in the room and operated the tower crane remotely.。
“I used to stay on the tower crane for half a day.，I dare not even drink water.，I'm afraid of going to the bathroom.。And sitting tens of meters high.，Especially for us female tower crane drivers.，The psychological pressure is particularly great.。”Zhou Xianchun said，“Since the tower crane uses the remote intelligent operating system,，I don't have to climb to work anymore.。”
Shaanxi Construction Machinery Co., Ltd. is the largest construction machinery leasing service provider in China.，It has more than 20,000 sets of rental equipment including tower crane equipment.。
“For enterprises，Intelligent tower crane will not only greatly improve work efficiency，But also can reduce that construction cost.。”Men Xinyan, vice president of Shaanxi Construction Machinery Research Institute, said.，“Nowadays，Increasing concentration of equipment leasing services for domestic engineering projects，Who uses intelligent equipment early?、Who uses it quickly?、Who uses it well?，Who has the advantage?。”
2020，Shaanxi Construction Machinery Co., Ltd. Construction Machinery Research Institute set up a special team，Research and development of intelligent tower crane remote operation platform。
Liu Difang, chief engineer of Shaanxi Construction Machinery Co., Ltd.“Three steps”Strategy：The first step is to ask the tower crane driver to come down from the tower crane.；Step two，Invite the tower crane driver into the office.；Step three，Invite the tower crane driver to drink coffee.。
Men Xinyan said with a smile.：“Simply put，The three steps are to realize the automation of tower crane respectively.、One person, multiple mechanization and unmanned。”
Men Xinyan still remembers，The R & D team had a heated dispute in the first collective discussion.。
“About the viewing angle of the viewfinder camera，A ball camera has been proposed.，Perform zoom tracking。It has been proposed to mount a camera on the variable amplitude trolley for vertical camera tracking.。”Men Xinyan said，“After site investigation and safety practicability evaluation，Finally, we conducted two sets of experiments.，Decided to use the car to zoom vertically.，Thoroughly solve the problem of blind area of vision。”
It is even more pleasing that，Just as R & D is entering a critical phase，In the core urban areas and key areas of Xi'an，5GSignal to achieve continuous coverage。
“We installed six panoramic HD cameras and one zoom camera that can dynamically track the location of the hook on the construction site.，With the help of 5GTransmission speed in milliseconds，It can transmit real-time pictures and data to the curved screen of the platform.，Provide the operator with an immersive operation experience。”Men Xinyan said。
The drivers reflected，Usually open the tower crane，The scene depends on the eyes.，Height、Empirical estimation of distance，Errors often occur.。Now the working environment is more comfortable.，The point is“Be able to hear and see clearly”，Low psychological pressure，And is more beneficial to stable operation.。
“It has been realized to invite the tower crane driver to the ground.，Currently we are working on the construction site 3.DModeling and optimal path planning，Strive to achieve one person to control multiple machines。”Men Xinyan said。
To enhance the innovation ability of enterprises，Last year, Shaanxi continued to implement the policy of incremental reward and subsidy for R & D investment of manufacturing enterprises.，411 manufacturing enterprises were rewarded.，Drive the increment of R & D investment 27.9.9 billion yuan。
