Description

A kind of communication system of crane safety monitoring management based on DP bus
Technical field
The present invention relates to crane peace keyholed back plate reason technical field, the communication system of a kind of crane safety monitoring management based on DP bus.
Background technology
Along with the development of national economy, handling machinery is widely used in every profession and trade and field.In recent years, the security incident of crane takes place frequently, and crane safety becomes the important leverage in industrial production activities.The departments such as handling machinery Quality Supervision and Inspection Center of country put into effect the national regulation of " GB/T28264-2012 " hoisting machinery security monitoring management system " " in recent years, and require large and medium-sized hoisting machinery popularization and application security monitoring management system (hereinafter referred to as safety supervision system).This system can improve crane safety, conveniently reviews device history duty, meets the requirement analyzing fault.Therefore, the crane in the range of compliant is required to configure security monitoring management system, and current domestic existence needs add-assembly or the crane of new clothes safety supervision system in a large number.GB/T 28264-2012 requires that crane is equipped with the hardware facilities such as signal collection unit, signal processing unit, and wherein information collection unit is used for reading information source data.The signal source equipments such as multiple instrument, sensor, encoder are had on crane, 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, needing the signal gathering unit for safety supervision system configuration various ways, as claimed weighing and torque signals of weighing instrument collection, interface is usually 4~20mA analog quantitys or RS485 bus;The wind velocity signal that anemobiagraph gathers, interface is usually 4~20mA analog quantitys 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 and communicates with lifting owner PLC, 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, it is therefore desirable to the signal gathering unit of configuration various ways.Communicate with lifting owner PLC as used, obtain signal number evidence from PLC, 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, the part crane run signal within PLC to be gathered, safety supervision system generally uses and communicates with lifting owner PLC, obtains signal number evidence from PLC.
The safety supervision system of prior art also exists the problems such as signal accuracy is low, autgmentability is poor, is digital instrumentation in current industry, 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 analog (some air velocity transducer primary signal is digital pulse signal) of sensor is digitized in gauge internal, transfer digital signal to analog signals again, it is transferred to PLC by analog quantity interface, again analogue signal need to be translated into digital signal by PLC.Modulus-digital-to-analogue multiple conversions in the process, its signal accuracy necessarily reduces.Interface module is the most relatively costly, PLC analog module, and 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, revising PLC hardware configuration, according to RS485 communication, then need to reset master-salve station, autgmentability is poor.
Summary of the invention
It is an object of the invention to the communication system of a kind of based on DP bus the crane safety monitoring management designed for the deficiencies in the prior art, the signal using DP bus communication weighing instrument, anemobiagraph and photoelectric encoder to be gathered uses DP bus communication to access safety supervision system host, the precision of signal transmission is high, new signal source equipment is facilitated to access, there is the advantage that simple in construction, favorable expandability and reliability are high, security monitoring management system can be realized with a low cost, improve crane control level further.
The object of the present invention is achieved like this: the communication system of a kind of crane safety monitoring management based on DP bus, including the crane safety monitoring management system being made up of safety supervision system host, PLC main frame, weighing instrument, anemobiagraph and photoelectric encoder, it is characterized in that PLC main frame is accessed safety supervision system host by Ethernet through the network switch, weighing instrument and anemobiagraph are accessed PLC main frame by RS485 bus through DP bus conversion module, and photoelectric encoder and DP bus conversion module are connected with PLC main frame by DP bus communication.
The present invention compared with prior art has the advantage that precision is high and reliability is high of simple in construction, signal transmission, can be realized with a low cost security monitoring management system, favorable expandability, increases new signal source equipment and accesses conveniently, improves crane control level further.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Refering to accompanying drawing 1, the crane safety monitoring management system that the present invention is made up of safety supervision system host 1, PLC main frame 3, weighing instrument 5, anemobiagraph 6 and photoelectric encoder 7, described PLC main frame 3 is accessed safety supervision system host 1 by Ethernet through the network switch 2, weighing instrument 5 and anemobiagraph 6 are accessed PLC main frame 3 by RS485 bus through DP bus conversion module 4, and photoelectric encoder 7 and DP bus conversion module 4 is connected with PLC main frame 3 by DP bus communication;Described safety supervision system host 1 uses industrial computer-IPC-510MB/AIMB-
