Description
Technical field
This utility model relates to crane peace keyholed back plate reason technical field, a kind of crane safety based on DP bus
The communication system of monitoring management.
Background technology
Along with the development of national economy, handling machinery is widely used in every profession and trade and field.In recent years, lifting
The security incident of machine takes place frequently, and crane safety becomes the important leverage in industrial production activities.Country's handling machinery matter
The departments such as amount Supervision Test Center put into effect the country of " GB/T28264-2012 " hoisting machinery security monitoring management system " " in recent years
Specification, and require large and medium-sized hoisting machinery popularization and application security monitoring management system (hereinafter referred to as safety supervision system).This system
Crane safety can be improved, conveniently review device history duty, meet the requirement analyzing fault.Therefore, compliant
In the range of crane be required to configure security monitoring management system, current domestic existence needs add-assembly or new clothes in a large number
The crane of safety supervision system.GB/T 28264-2012 requires that crane is equipped with the hardware such as signal gathering unit, signal processing unit
Facility, wherein information acquisition unit is used for reading information source data.The letters such as multiple instrument, sensor, encoder are had on crane
Number source device, these signal source equipments all have respective signaling interface and transmission means (including physical interface and logic interface),
Safety supervision system, in order to gather these signals, needs to be incorporated in safety supervision system host multi-form signaling interface.In order to realize
Above-mentioned functions, needs the signal gathering unit for safety supervision system configuration various ways, as claimed weighing and power of weighing instrument collection
Square signal, interface is usually 4～20mA analog quantitys or RS485 bus；Anemobiagraph gather wind velocity signal, interface be usually 4～
20mA analog quantity or RS485 bus；The lifting altitude signal that encoder gathers, interface is usually Profibus DP(and is called for short DP)
Bus or other fieldbus；The turning arm rack position signal that encoder or level sensor gather, interface is usually
DP bus or RS485 bus.The method of the safety supervision system host above-mentioned signal source of acquisition generally uses leads to lifting owner PLC
Letter, obtains signal number evidence from PLC or direct and each signal gathering unit communicates acquisition signal number evidence.
Due to the multiformity of above-mentioned signaling interface, no matter which kind of scheme, all there are the needs of signaling interface conversion, therefore
Need to configure the signal gathering unit of various ways.Communicate with lifting owner PLC as used, obtain signal number from PLC
According to, then need to configure PLC analog module, RS485 module etc..As used direct and each signal gathering unit to communicate, then
Need to configure PC RS485 interface card, DP interface card, analog quantity interface card etc..According to gb specification, due in PLC to be gathered
The part crane run signal in portion, safety supervision system generally uses and communicates with lifting owner PLC, obtains signal source from PLC
Data.
The safety supervision system of prior art also exists the problems such as signal accuracy is low, autgmentability is poor, is numeral in current industry
Changing instrument, if weighing or wind velocity signal is transmitted by analog quantity, then there is the situation of digital-to-analogue two times transfer.The original mould of sensor
Intend signal (some air velocity transducer primary signal is digital pulse signal) to be digitized in gauge internal, then by digital signal
Transfer analog signals to, be transferred to PLC by analog quantity interface, again analogue signal need to be translated into numeral letter by PLC
Number.Modulus-digital-to-analogue multiple conversions in the process, its signal accuracy necessarily reduces.Interface module is the most relatively costly, PLC mould
Analog quantity module, RS485 module etc. is above common analog I/O module.It addition, if desired increase new signal source, it is necessary to increase
New signal gathering unit, revises PLC hardware configuration, according to RS485 communication, then needs to reset master-salve station, autgmentability
Difference.
Utility model content
The purpose of this utility model is a kind of based on DP bus the crane peace designed for the deficiencies in the prior art
The communication system of full monitoring management, the signal using DP bus communication weighing instrument, anemobiagraph and photoelectric encoder to be gathered uses
DP bus communication accesses safety supervision system host, and the precision of signal transmission is high, facilitates new signal source equipment to access, and has structure letter
The advantage that list, favorable expandability and reliability are high, can be realized with a low cost security monitoring management system, improve crane control further
Level.
The purpose of this utility model is achieved in that the communication of a kind of crane safety monitoring management based on DP bus
System, including the crane safety monitoring being made up of safety supervision system host, PLC main frame, weighing instrument, anemobiagraph and photoelectric encoder
