The past 20 years have been the rapid development of the real estate industry. From the early 7-story building to the current 100-meter-high building, if you want to ask what has contributed the most, it must be the tower crane.Tens of thousands of tall buildings rise from the ground, and every grain of sand and stone is transported to the upper floors by the powerful vertical transportation capacity of the tower crane. E07 CC1101 Kit However, while the tower crane is efficient, it also brings great risks.Tower cranes are heavy-duty equipment that operate at high altitudes, and there is a high probability of accidents. According to the survey, safety accidents caused by illegal operation and overloading of tower cranes accounted for 30% of the overall safety accidents on the construction site, which brought great risks to people.solutionWith the continuous development and progress of science and technology, it is very possible to have a system for remote visual monitoring of equipment status. The status of large equipment such as tower cranes should be monitored in real time to avoid accidents.The solution uses sensor technology to measure the displacement of the top of the tower crane to determine whether the tower crane has shifted its position; 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. Traditionally, the cables used to connect sensors are cables. The construction on the tower crane is difficult and the maintenance is very troublesome. Moreover, the interference problem during long-distance transmission is also known as a major problem. Through radio transmission technology, the data is transmitted through wireless data 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 realize remote monitoring functions without going to the site.
