Abstract

The invention relates to an embedded tower crane safety monitoring device which comprises an embedded controller, a wind speed sensor, an encoder for acquiring the rotation angle of a motor of a main shaft of a tower crane, a height sensor, an amplitude sensor and a weight sensor, wherein a liquid crystal display device, a keyboard, a memory and a control output module are connected on the embedded controller; the signal output end of the encoder and the wind speed sensor are connected with a CPLD logic device, the CPLD logic device is in series connection with the embedded controller, and the CPLD logic device is used for calculating the rotation angle, the wind speed and the wind direction of the main shaft of the tower crane; the height, the amplitude and the weight sensors are connected on the embedded controller through an analog channel; the embedded controller stores all the acquired parameter values in the memory, displays result information on the liquid crystal display device and compares with preset values, when the acquired information values are larger than the preset values, a signal of closing the tower crane is outputted through the control output module.

Description

technical field [0001] The invention relates to an embedded safety monitoring device, in particular to a tower crane safety monitoring device. Background technique [0002] At present, the monitoring instruments mainly used in some tower cranes are monitoring instruments that realize a single function, such as lifting moment limiter and lifting weight limiter. The response time is slow, so some emergency situations of the tower crane cannot be handled in real time. According to statistics, most of the safety accidents in tower cranes are due to the fact that the operators cannot accurately obtain the parameters of the current working state of the tower crane, which makes the tower crane overloaded. Contents of the invention [0003] In order to solve the safety problems existing in existing tower cranes and the problem that tower crane operators cannot know the current working state parameters of tower cranes at any time, the present invention provides an embedded tower c...
