Problems solved by technology

Reduced reliability and shortened service life due to gear transmission wear
In addition, its cost is high, with a price of several thousand yuan, which is unacceptable in the market.
[0008] Anyone can operate the tower crane without RFID management, so many tower crane safety accidents in the past, a considerable part were caused by working without a license

Embodiment Construction

[0025] A tower crane safety management system of the present invention comprises: a server, a tower crane safety management platform, a GPS / GPRS communication module, a torque limiter host with RFID management function, and the torque limiter host is provided with an RFID sensing chip and an RFID sensor , the torque limiter host is respectively connected with: weight sensor, amplitude sensor, height sensor, rotation angle sensor, wind speed sensor through CAN bus, as figure 1 shown.

[0026] work process:

[0027] When the tower crane driver is working, he first uses the RFID card to open the torque limiter host through the RFID sensor, and the torque limiter host unlocks the tower crane to enter the working state. At this time, the tower crane driver can perform various work operations. When the tower crane driver is operating in various working conditions, each sensor is also continuously sending the detected signals to the torque limiter host, and the torque limiter host p...

Abstract

A tower crane safety management system comprises a tower crane safety management platform and a server. The server is connected to a moment limiter host through a GPS / GPRS communication module; the moment limiter host is provided with an RFID sensing chip and an RFID sensor; and the moment limiter host is respectively connected to a weight sensor, an amplitude sensor, a height sensor, a rotary angle sensor and a wind speed sensor through CAN bus. During working of the tower crane safety management system provided by the invention, each sensor sends collected information to the moment limiter host through the bus; the moment limiter host collects, analyzes and calculates the information, and then sends the information to a display for displaying; alarm information is sent to an alarm for alarming; control information is sent to a controller for control protection; and communication information is sent to the GPRS module, and enters into the tower crane safety management platform through Internet network.

Description

technical field [0001] The invention relates to a tower crane safety management system. Background technique [0002] At present, the tower crane safety management system products in the domestic market generally have the problems of low sensor detection accuracy, poor reliability, short service life and high cost, which makes users spend a lot of money, but cannot achieve the desired effect. [0003] At present, the amplitude / height sensor products on the market basically use multi-function mechanical limiter sensors. The data of the height of the hook and the travel range of the trolley can be judged by the resistance value of the device. The advantage is that the resistance value of the potentiometer will not be lost when the tower crane does not send power to the sensor, and the supply of goods in the market is sufficient; [0004] However, the multifunctional mechanical limiter sensor is a mechanical transmission contact to detect the height of the hook and the walkin...
