Problems solved by technology
[0004] (1) The environment of the port is relatively harsh. The sensors of the acquisition system are vulnerable to high temperature, high humidity, high salinity and other environments. The sensors are prone to zero drift, loss of accuracy, or even damage
The acquisition system does not have a good detection method to detect abnormal data, and the collected bad data will affect the final fault diagnosis;
[0005] (2) The crane has a relatively large space and various systems, and the data acquisition systems of each subsystem often exist in isolation
The sensor data cannot be effectively combined with the working conditions and safety status of the crane, and the acquisition system cannot comprehensively summarize the crane data;
[0006] (3) The data acquisition system adopts a distributed architecture. Due to the long communication distance, it is difficult to ensure strict data synchronization
If the data cannot be effectively established under strict time tags, functions such as fault diagnosis and life prediction will be affected;
[0007] (4) There are many detection points in the crane equipment acquisition system, and it is necessary to ensure the detection and collection under all-weather operation conditions, and the amount of collected data will be very large
If the acquisition and processing module does not have a strict and effective data screening function, key data will often be submerged in massive data;
[0008] (5) There are many data acquisition system manufacturers, the external interface of the acquisition software is not uniform, and the lack of data sharing between the acquisition system and the acquisition system and the electrical system limits the comprehensive crane fault diagnosis

Embodiment Construction
[0037] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0038] The invention provides a tire crane distributed data acquisition system and method. The entire collection system of the tire crane is divided into three parts according to the location, which are the trolley platform collector, the power room collector and the electrical room collector. The trolley platform collector includes the detection of the driver's cab, trolley device and hoisting mechanism; the power house collector includes the detection of the power house and the power side cart device; the electrical room collector includes the electrical room, inclined ladder and electrical room side cart device detection. The collection systems are interconnected through the Ethernet industrial bus, and at the same time, the data of the electrical system on the crane is collected synchronously on demand. The electrical sy...

The invention discloses a distributed data collection system and method of a tyre crane. The system comprises a trolley platform collector, a power room collector and an electrical room collector. Thetrolley platform collector comprises a cab monitory point, a trolley device monitory point and a hoisting mechanism monitory point. The power room collector comprises a power room monitory point anda power side cart device monitory point. The electrical room collector comprises an inclined ladder monitory point, an electrical room monitory point, an electrical room side cart device monitory point and an OPC connector, and is connected with a centralized control center server through the OPC connector. The trolley platform collector, the power room collector and the electrical room collectorare in signal connection with an interchanger. The electrical room collector serves as a main collector, the power room collector and the electrical room collector serve as auxiliary collectors, dataof the monitory points are collected and sent to the main collector by the auxiliary collectors, and the main collector collects the data of all the auxiliary collectors.
Description
technical field [0001] The invention relates to crane equipment fault diagnosis and distributed data acquisition technology, more specifically, to a tire crane distributed data acquisition system and method. Background technique [0002] As the main material transportation tool, hoisting machinery has been frequently used in industrial production and infrastructure construction. Once an accident occurs, the economic loss will be heavy and the social impact will be bad. Due to the high manufacturing cost of hoisting machinery, the social impact after the accident is bad, and the economic loss is relatively large, so it is of great social significance to carry out preventive assessment in advance. Effective fault assessment of hoisting machinery plays an important role in promoting technological progress in hoisting and machinery manufacturing and improving the safety performance of large-scale hoisting devices, and will directly relate to the technological progress of the nat...
