Set up for crane process characteristics and monitoring requirements

This unit is the recording part of the Crane Monitoring System , the system function is finally realized in this unit, according to the crane process characteristics and monitoring requirements, put forward the requirements of the next monitoring system:

(1) Real-time storage of the next acquisition unit transmission of the operation status and fault information.

(2) To achieve the archiving and other accident tracing functions.

(3) System self-calibration function, to ensure that their own reliable.

(4) Real-time display bridge machine operation status and fault information.

(5) The function of filtering and data conversion is realized.

(6) Logical control and system comprehensive configuration.

According to the above functional requirements and the interface problem of the next acquisition unit, the next scheme is set as the core of industrial computer. The host computer adopts V C + + to write the monitoring software with real-time ability. For the above design requirements, the upper record, data processing unit hardware to make the following optimization:

(l) Use passive cooling motherboard. That is, the motherboard does not have a mechanical fan, using heat sink heat.

(2) Screen fuselage integrated design, and select the touch screen.

(3) Internal discarded mechanical hard disk, using anti-vibration flash-type solid-state drive. Avoid the most sensitive parts inside the industrial computer.

(4) power supply person plus D C d C DC voltage regulator module.

Crane monitoring software has the ability to communicate with Siemens PL C via O PC, which records the operating parameters of cranes in real time. The reasons for choosing OPC technology:

(l) Versatility. At present, the mainstream industrial control manufacturers are supporting the technology.

(2) Its technology has hardware and software independence, suitable as a general product. To prepare crane safety monitoring and management system generalization.

(3) The technology is open, the software is based on its internal and transparent characteristics. For the crane safety monitoring and management system for real-time requirements is very high, the upper software using C 20 as the main programming software, it has the characteristics of the crane and data collected to analyze the detailed parameters of the crane, to make a targeted fatigue analysis, life evaluation, while improving and improving the design of cranes.

2.3.4 Video Capture Unit

Crane safety monitoring and management system requires video surveillance, considering that it and monitoring performance of the main system is not associated with a small, if combined with the monitoring system, it is very resource-intensive, and may lead to the overall monitoring system stability degradation, it is independent. Bridge erecting machine monitoring point standard requirements: the state of the hole, the state of the frame beam, the synchronous state of the beam car. It is aimed at the synchronous state monitoring of the transport beam car, the beam is up to 03 m, and the monitoring angle is less than one. There are two probes installed in the front of the bridge-erecting machine, the distance is not less than m, there may be interference phenomenon. This requires a high level of video capture, with a professional industrial camera and camcorder, and the ability to provide long -distance transmission.

3. Summary

Crane is an important tool and equipment to realize the mechanization and automation of production process in modern industrial production and hoisting and transportation, in order to monitor the operation state of hoisting machinery efficiently and quickly, to improve the handling efficiency, to reduce the time of failure, to improve production efficiency and to ensure the safe operation of cranes, both academically and engineering are of great significance. This paper has carried on the research to the general Crane Crane Safety monitoring and management system, and has made the design with the bridge Crane Safety monitoring and management system as an example.

This paper analyzes the structure features and functions of the system, combined with the development of modern monitoring system, through the comparison of communication methods, determines the communication mode between the host computer, the lower machine, the field equipment, and adopts the Siemens 5 7,130 0 PL C to monitor the bridge-erecting machine, using S T E P 7 software to complete the process Design, with C + ten development of the host computer monitoring software to complete the proposed requirements.
