[0020] The intelligent control center in the spreader is connected to a remote terminal, which can be a computer or a mobile phone. The computer is connected to the intelligent control center through the Internet of Things and realizes remote operation. The mobile phone connects to the intelligent control center by scanning the QR code display on the spreader to realize remote operation.

[0021] In this sling, the pair of pressure sensor assemblies are symmetrically arranged on both sides of the fastening part, and the middle part of the balance bar has a balance adjustment slider. The pressure signal deviation value P transmitted by the pair of pressure sensor assemblies is ≥ 10%.

[0022] The operating principle of the hoist is as follows: balance is performed before use. For lifting lighter objects, two sets of pressure sensor components sense pressure and transmit it to the intelligent control center. When the deviation value P of the two sets of pressure is less than 5%, normal lifting operations can be performed; when the deviation value P of the two sets of pressure is greater than or equal to 5%, the balance adjustment slider needs to be activated until the deviation value P is less than 5%; the over-limit value is set remotely before lifting. Once the lifted object exceeds the limit, the intelligent control center will activate the alarm to alert the monitoring personnel. The lifting limit can be adjusted by scanning the QR code on the mobile phone to connect to the intelligent control system, or by remotely connecting to the intelligent control system through a computer. The set over-limit value can be 2%, 5% or 10%; during the lifting of heavy objects, the pressure sensor is subjected to pressure and outputs the corresponding analog quantity to transmit to the intelligent control center. The intelligent control center controls the data displayed on the pressure display screen according to the received signal. During the entire operation, the video acquisition system can collect and store the impact on the construction site, and the remote terminal can view recent construction videos.
