GPRS/CDMA based automatic safe monitoring system for tower crane

Abstract

The invention relates to a tower crane monitoring system, in particular to an automatic tower crane monitoring system based on GPRS / CDMA, which comprises a tower crane side function control console (1) and a control room side control console (3), wherein the tower crane side function control console (1) is wirelessly connected with the control room side control console (3) via a GPRS / CDMA wireless network (2). The invention has the advantages of reducing the possibility of security incidents in the operation of the tower crane, improving the operation safety of the operation of the tower crane, and fulfilling requirements of users on the operation of the tower crane; in addition, the operation of the tower crane is safer, more stable and more effective.

Description

technical field [0001] The invention relates to a tower crane safety monitoring system, in particular to a GPRS / CDMA-based tower crane automatic safety monitoring system. Background technique [0002] At present, the tower crane monitoring system mainly adopts the operation mode for stand-alone work, and only monitors the operating status of a single tower crane. It is under the multi-machine working mode, that is, there are multiple tower cranes working at the same time or in time-sharing on an infrastructure construction site, which requires multiple tower cranes to be able to monitor their operating status in real time. Moreover, in order to To better grasp and control this information, it is also required to have the functions of network connection between multiple tower cranes and network connection between multiple tower cranes and the host computer. Therefore, tower crane monitoring only for stand-alone It is difficult for the system to adapt to this new change. [...

[0002] At present, the tower crane monitoring system mainly adopts the operation mode for stand-alone work, and only monitors the operating status of a single tower crane. It is under the multi-machine working mode, that is, there are multiple tower cranes working at the same time or in time-sharing on an infrastructure construction site, which requires multiple tower cranes to be able to monitor their operating status in real time. Moreover, in order to To better grasp and control these information, it is also required to have the functions of network connection between multiple tower cranes and network connection between multiple tower cranes and the host computer. Therefore, tower crane monitoring only for stand-alone The system has difficulty adapting to this new change

[0003] At the same time, some existing tower crane monitoring systems try to use some simple networking methods to enable information exchange between tower cranes, for example, using point-to-point data transmission stations to form a ring network, etc., but the actual construction site The working conditions are different, for example, the conditions of the construction site are different, the interference conditions are different, the wireless environment in the air is different, the shock pulse influence of various instruments and equipment on site is different, and the nature is different. different situations etc.

Due to the large changes in the communication environment, this puts forward higher reliability and security requirements for the actual wireless network on site. The on-site wireless network has disadvantages such as difficulty in network connection, high probability of disconnection, and unstable communication, which seriously affects the normal operation of the networked tower crane monitoring system and limits the effectiveness of the monitoring system
