System functions: 1) tower operating condition test, display and recording functions, including the magnitude of the tower crane, height, from the weight / torque, rotational angle, wind speed and angle data, the data tower crane during operation can be recorded in the local monitor, and also can be stored at the remote server to meet the tower crane accident analysis and analysis of tower crane operation rules requirements; 2) tower crane regional security features can be set up to 20 different types of protected areas can be realized on power lines, schools, roads, houses, office buildings and other features of the area of ??protection, to ensure the tower crane safety of the premise, as far as possible to achieve maximum space tower crane operating area; 3) tower crane anti-collision function, the magnitude of the position of the tower crane, height position and rotational position detected in real time via wireless transmission network, while up to 32 tower crane same construction environment to form a wireless monitoring network, the operating status of the data can be different tower crane tower crane in Inter delivery. Each tower can be based on the data of the other tower crane and tower crane anti-collision calculations, achieve distance and altitude warning alarm, and the alarm on or off the unsafe operation of the power direction based on the calculated result of the anti-collision; 4) tower crane tilt monitoring function, by measuring the angle of inclination of the tower crane to analyze the security status of the tower crane, be alert when the tilt tower reaches a critical state, reminding tower crane caution; 5) tower wind speed monitoring function, process tower crane operation The ambient wind speed real-time monitoring, alert drivers for safe operation; 6) tower crane safety status of remote monitoring capabilities can remotely tower crane running real-time monitoring, remote management to meet the needs of the tower crane.
