Remote management scheme based on wireless communication

In the past 20 years, the real estate industry has experienced rapid development in the past 20 years. From the 7-story building in the early stage to the 100-meter-high building, if you want to ask what has contributed the most, it must be the tower crane.

From the level of ten thousand feet of high-rise buildings, every sand and stone are transported to the high-rise by the powerful vertical transportation capacity of the tower crane. However, while the tower crane is efficient, it also brings great risks.

Tower cranes are heavy-duty equipment and operate at high altitudes, so there is a high probability of accidents. According to the survey, the safety accidents caused by the illegal operation and overloading of tower cranes account for 30% of the overall safety accidents on the construction site, which brings great risks to people.

solution

With the continuous development and progress of science and technology, it is very possible to have a system for remote visual monitoring of equipment conditions. The status of large equipment such as tower cranes should be monitored in real time to avoid accidents.

The scheme uses sensor technology to measure the displacement of the top of the tower crane to determine whether the tower crane has a position offset; by measuring the wind speed, it is set to stop working when the wind speed exceeds a certain level; by measuring the tension value of the cable, Determine whether the cable is safe and whether the weight of the equipment exceeds the rated load.

The solution relies on radio transmission technology. The traditional cable connecting the sensor is a cable. It is difficult to construct on the tower crane, and the maintenance is very troublesome. Moreover, the problem of interference during long-distance transmission is also known as a major problem. For transmission, wireless transmission can be achieved without wiring in the middle. At the same time, through long-distance mobile communication technologies such as 4G or Ethernet, safety supervision departments such as construction site safety officers, tower crane rental companies, and construction units can also achieve remote monitoring functions without going to the site.

With the help of automation technology, the program runs automatically through programming, and sets the threshold. When the threshold is not exceeded, the equipment can work normally. When the threshold is exceeded, the equipment is automatically shut down and reported directly to the operator.

Solution advantage

1. Reminders can be made for driver violations to improve safety awareness.

2. For supervision units, remote monitoring can be achieved without going to the site.

3. For the tower crane owner, check the operation status of the equipment in real time, carry out maintenance in time, and prolong the service life.

4. Aiming at the regulatory department, remotely monitor the status and eliminate potential safety hazards.
