Field real-time acquisition and storage device for operating parameters of hoisting mechanical system

Abstract

The invention relates to a field real-time acquisition and storage device for operating parameters of a hoisting mechanical system. The field real-time acquisition and storage device mainly solves the technical difficult point that a conventional crane lacks data in design, use management and state evaluation. The field real-time acquisition and storage device adopts the following technical scheme that: the field real-time acquisition and storage device for the operating parameters of the hoisting mechanical system comprises a data acquisition device for monitoring parameter information of hoisting machinery, a microprocessing unit, a power supply unit, a real-time clock unit, a data storage unit and a communication network interface unit; an output interface of the power supply unit is connected with the power supply input end of the microprocessing unit; an output interface of the real-time clock unit is connected with a clock input interface of the microprocessing unit; a signal of the data acquisition device for the parameter information of the hoisting machinery is subjected to analog digital conversion and accesses an input interface of the microprocessing unit; a data output interface of the microprocessing unit is connected with an input interface of the data storage unit; and an interface of the communication network interface unit is connected with a communication interface of the microprocessing unit.

technical field [0001] The invention relates to an on-site real-time acquisition and storage device for operating parameters of a hoisting machinery system, which belongs to an on-site real-time acquisition and storage device for operating parameters of hoisting machinery systems in various forms and models. The system parameters include two parts: basic parameters and operating parameters. technical background [0002] At present, my country requires that hoisting machinery must be equipped with over-limit safety protection devices such as lifting weight, lifting height and operating position. These safety protection devices mainly limit and control the lifting weight, lifting height and operating position. Monitor other parameters of the equipment.

Problems solved by technology

[0002] At present, my country requires that hoisting machinery must be equipped with over-limit safety protection devices such as lifting weight, lifting height and operating position. These safety protection devices mainly limit and control the lifting weight, lifting height and operating position. Monitor other parameters of the device

[0003] Moreover, most of the existing hoisting equipment in my country does not have the functions of real-time acquisition, recording and storage of multiple operating parameters, and it is impossible to extract real-time data and historical data of hoisting machinery on-site operation; there is no full-process tracking of in-service cranes

Driven by production efficiency and economic interests, the user may occasionally operate the crane unsafely, or remove the overload limiter intentionally because the safety protection device hinders actual use.

Then, in this period of time, the safe use of the crane cannot play an effective role, and accidents often occur, causing huge waste of property for the country and the people.

One of the reasons for this situation is the lack of a storage device for collecting and recording crane system parameters for a long time, and the historical data cannot be restored, so the occurrence of the above hidden dangers cannot be eliminated.

[0004] The current single-function safety device can only prevent overloading, and cannot record its actual operating parameters, resulting in insufficient data basis in the formulation of specifications, and often refers to the parameters of other countries to determine, such as determining the crane The load spectrum has two main data: the actual lifting load of each operation cycle and the number of operation cycles, because it cannot be automatically calculated from the actual operation, it can only be based on the total operation tonnage and operation time recorded manually, or refer to foreign countries Specifications, roughly estimated to determine the load state and utilization level of the crane, and then obtain the load spectrum

In addition, from the perspective of maintenance, due to the inability to provide accurate crane operation data to the maintenance department, the maintenance cycle is inaccurate, often resulting in over-maintenance and disrepair
