Embodiment 1

[0036] Please refer to shown in Fig. 1, the recording device of hoisting machine running state of the present invention is arranged in a sealed box body, and this box body has the performance of high temperature resistance, high pressure resistance, corrosion resistance, and is powered by external power supply, comprises:

[0037] The data acquisition unit is externally connected to the industrial computer and the programmable logic controller (PLC) installed on the hoisting machinery through the network hub (HUB), and collects the operation of the hoisting machinery through the industrial computer and the programmable logic controller (PLC). The signal is converted into a data signal. The collected signal includes the wind speed signal, the motor signal (including the current, voltage, and speed of the motor) of the main mechanism of the hoisting machinery such as walking, lifting, turning, and luffing, the driver, the brake, and the important limit. More than 120 important pa...

Embodiment 2

[0041] See also shown in Fig. 2, the specific steps of the method for recording hoisting machine running state of the present invention are:

[0042] Start the recording device first, use the data acquisition unit of the device to collect the operating status signal of the hoisting machinery, and convert it into a data signal, and the data acquisition unit communicates with the industrial computer installed on the hoisting machinery through the network hub (HUB) respectively. It is connected with the programmable logic controller (PLC), and collects the operation signal of the hoisting machinery through the industrial computer and the programmable logic controller (PLC) and converts it into a data signal. The collected signal includes the wind speed signal, the walking and lifting of the hoisting machinery The signal of the motor (including the current, voltage, and speed of the motor) of the main mechanism such as , slewing, and luffing, more than 120 important parameter signa...

It starts with data processing unit analyzing the data signal and coordinating relevant component, completing the data processing, with data storage unit timely storing and updating data.

Description

technical field [0001] The invention relates to operation monitoring and accident records of large hoisting machinery, in particular to a device and method for recording the operating state of the hoisting machinery. Background technique [0002] Entering the 21st century, with the accelerated process of global economic integration, water transportation has shown a steady development trend, and the construction of wharves and ports is in a period of rapid development. As a new force in port construction, large-scale hoisting machinery is also growing steadily and rapidly. Hoisting machinery belongs to special equipment, and once an accident occurs, it will cause heavy personal casualties and serious economic losses. In response to this situation, many port companies have actively adopted specialized and modern production processes and equipped with complete sets of defense equipment, which has reduced the probability of accidents to a certain extent. However, for some unavo...
