Problems solved by technology

[0002] In recent years, tower cranes have been widely used in the construction industry due to their high-efficiency vertical transportation capabilities. However, the following problems exist in the operation of construction tower cranes: Safety accidents caused by hoisting action, tower crane collision, structural fatigue instability and other reasons continue to occur; on the other hand, when tower crane operators perform hoisting operations, judging the position of hoisted heavy objects is only achieved by visual inspection, and there are operational blind spots
[0003] The above problems seriously threaten the health of construction workers and cause huge property losses. It is imperative to prevent and reduce tower crane safety production accidents.

Embodiment 1

[0042] see Figure 1~2 , In an embodiment of the present invention, a tower crane safety monitoring system is provided, the system includes a main control subsystem and a data acquisition subsystem, an operation subsystem, an information management subsystem, and an alarm subsystem communicated with it.

[0043] The data acquisition subsystem is used to collect the data information of tower crane operation, and transmit the data information to the main control subsystem, which is used to analyze and process the data information, and control the alarm subsystem.

[0044] The main control subsystem includes a controller and a PLC module connected thereto. The PLC module is used to receive control commands from the controller, convert the control commands of weak current signals into strong current signal commands, and send them to the alarm subsystem.

[0045] The data acquisition subsystem includes a camera, a radar detector, a wind speed sensor, an altitude sensor, an amplitud...

Embodiment 2

[0069] A monitoring method for a tower crane safety monitoring system, the method comprising the steps of:

[0070] Step 1: Preset the safety threshold in the main control subsystem, the data acquisition subsystem collects the data information of tower crane operation, and transmits the data information to the main control subsystem;

[0071] Step 2: The main control subsystem compares the collected data information with the preset threshold, and sends out an alarm signal and emergency braking information when the data information exceeds the preset safety threshold.

Embodiment 3

[0073] The weight sensor collects the load weight of the hook of the tower crane and transmits the weight information to the main control subsystem. The main control subsystem compares the weight information with the preset safety threshold. If the value of the weight information exceeds the preset safety threshold, on the one hand, The main control subsystem sends an alarm signal to the alarm subsystem, and the alarm subsystem in the cab sends out an alarm, prompting the driver to operate incorrectly and there are hidden dangers; on the other hand, the main control subsystem sends emergency braking information, and the tower crane stops working.

[0074] Compared with prior art, the beneficial effect of the present invention is:

[0075] 1. The tower crane safety monitoring system of the present invention, by arranging the main control subsystem and the data acquisition subsystem, the operation subsystem, the information management subsystem, the alarm subsystem connected with...
