The tower crane side control console comprises an environmental monitoring unit, a hoisting information monitoring unit, a tower crane base monitoring unit, a carriage information monitoring unit, an information collection, isolation and sorting unit, a FPGA-based main control unit, a storage unit, an output control unit, an expandable key display unit and a wireless transmission unit; wherein the information collection, isolation and sorting unit is one-way connected with the FPGA-based main control unit; and the storage unit, the output control unit, the expandable key display unit and the wireless transmission unit are respectively both-way connected with the FPGA-based main control unit. The invention has the advantages of reducing security incidents during operation of the tower crane, improving the safety of the operation of the tower crane, and satisfying the control requirements of users on 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 an FPGA-based tower crane automatic safety monitoring system. Background technique [0002] The existing tower crane monitoring system mainly adopts single-chip computer, industrial computer, PLC, ARM as the main control unit of the monitoring system. The main control unit is the core component of the whole system, responsible for information fusion, processing, analysis, storage, transmission and other functions. Therefore, as the main control unit, it should first have a powerful data processing function. Secondly, because various information of the system comes from different sensor units, and in order to realize storage, output, keyboard, display and other functions, it must provide rich peripheral circuit interfaces. This puts forward more complex requirements on the main control unit, including processing speed and interface capability. As a single-chip microcompu...

Therefore, as the main control unit, it should first have a powerful data processing function. Secondly, because various information of the system comes from different sensor units, and in order to realize storage, output, keyboard, display and other functions, it must provide rich peripheral circuit interfaces. This puts forward more complex requirements on the main control unit, including processing speed and interface capabilities.

As a single-chip microcomputer, it is limited by its processing speed regardless of its processing capability and peripheral interface capability; PLC is a relatively commonly used device in industrial control, but its advantages are often reflected in the ability to directly control industrial equipment, and there is no processing capability. What are the advantages, and there are relatively few engineers who are familiar with PLC, and they are often automation professionals, which will limit the use of later maintenance; industrial computers and ARM are more expensive, mainly because of their operating systems, which are at a disadvantage in terms of cost control
