Description
Technical field
The invention belongs to field bus device administrative skill field, relate to a kind of field bus device method for managing and monitoring.
Background technology
From the eighties in 20th century, fieldbus is strong because of its reliability, communication is quick, compatible wide, cost is low etc., and a series of advantages are able to extensive use in industrial automatic control.Increasingly automated, the digitlization of producing in addition, living, the intelligent development that also promotes field bus control system and field bus device, various device management system and field bus device are of a great variety at present, can satisfy the needs of various industries.But also there are some very important problems in present most of equipment management systems.
Along with the development of fieldbus, there have been many companies according to the requirement in market to develop separately equipment management system at present, and obtained a large amount of application, reaction is good.Wherein more representational have following two kinds: the process device manager SIMATIC PDM of Siemens Company and the AMS intelligent device management system of Ai Mosheng company.These two kinds of equipment management systems have represented respectively the implementation of two kinds of equipment management systems, comprise wherein the module composition and the information interaction of field apparatus and equipment management system, the two all is mutually different.Different just because of its mechanism, so that the application of two kind equipment management systems also differs widely.
1) Simatic PDM system
Simatic PDM is the equipment management system that a cover develops for the Profibus field bus system.This cover system be one be used for to field apparatus and automation component show, the general utility tool of test run, diagnosis and maintenance.Its distinguishing feature is exactly: integration, its purpose of design is tried hard to exactly with field devices integration.In this cover system, allow to realize integrated by multiple method; DD by the device fabrication merchant; By agreement PROFIBUS PA-Profile V3.0; By the HCF(HART communication foundation) catalogue realize the integrated of equipment.
The management work of this complete equipment management system of PDM mainly realizes by equipment itself.The functions such as the parametrization of equipment, diagnosis, realization optimization all are that the form with functional block realizes in equipment, and the information such as messaging parameter, device parameter, argument structure and device action of equipment all offer the system integration user of equipment by the EDD file simultaneously.PDM has a top-heavy system configuration.It is very high to the requirement of equipment manufacturers, needs equipment manufacturers just to consider the management work such as maintenance to equipment, optimization in production equipment and realizes in equipment with the form of functional block.
Realize that at client layer which kind of field bus protocol the theoretical method of integration of equipments does not require based on equipment, therefore uses the PDM system of this theoretical method very extensive at usability by using the EDD file.But also just because of this theoretical method, PDM has a strict requirement to equipment, and namely field apparatus must provide the EDD file, and for the field apparatus of not supporting EDD, this cover management system is inapplicable; Simultaneously because the groundwork of this devices in system management all is form by functional block realizes in equipment, require very high to the device fabrication merchant, the function that therefore can realize is fairly simple, limited, and the increase that the user of equipment also basically can not be extra is to the management function of field apparatus.So from the angle of equipment control, the practical function of its equipment control is very limited.
Except requiring too high to device fabrication producer, can't be general with all devices outside, PDM diagnoses mainly for equipment and adds up, and for the field management aspect function of this specific industry of power plant a little less than, can't when need to safeguarding, equipment fault appearance or equipment provide corresponding maintenance guidance, can not automatically generate maintenance or maintenance work ticket, the failure diagnosis of equipment can not be dissolved in the middle of the industrial flow of whole power plant industry.In addition, PDM does not preserve fully to the historical data of whole field bus device, although PDM can generate alarm log, and preserve with the CSV form, but when PDM computer break down and when restarting, when reopening PDM, historical data before will be lost.
2) AMS equipment management system
The AMS of Ai Mosheng is a system in combination, has comprised AMS facility information platform, AMS intelligent device management system, AMS mechanical equipment state management system, AMS performance detecting system and AMS real-time optimization system.Integrated application by above-mentioned five systems can realize the functions such as the management of intelligence instrument valve arrangement, capability of engineering equipment monitoring, process device Performance Detection and system protection.
Wherein, the AMS equipment management system is from the angle of the system integration, user's requirement modularize further consisted of independently management system and with its unified being integrated on the information platform.The advantage of this system is: the parameter information of all field apparatuss all is embodied in the unified interface; When carrying out a certain function, the user can travel through all field apparatuss.
In addition, AMS integrates data acquisition, data analysis, therefore will carry out " connection " with equipment by DCS system or direct line.At present, AMS can only utilize software and hardware and the wiring of the DCS system of a few companies such as Ai Mosheng, communicate with devices communicating, and during for most applications, just must be connected on simultaneously on the equipment by multiplexer and DCS system, so just cause equipment to add more complicated, had a strong impact on the autgmentability of system.
Summing up above two kinds of equipment management systems commonly used can find out, the equipment management system of main flow has several defectives at present:
1. high to equipment requirement.Most of equipment management systems all require equipment that the EDD file of facility information file such as PDM, the DD file of AMS must be able to be provided.Therefore, system requires equipment must be able to generate, provide corresponding facility information file during operation, must improve like this requirement to equipment, in case equipment can't provide message file, then management system can't be brought this equipment into management area, has reduced versatility.
2. autgmentability is poor.Therefore most of equipment management systems all will communicate with equipment, must utilize software and hardware and wiring and equipment connection, and the cost of the whole equipment management system that must increase like this and complexity also will inevitably have influence on original DCS system.
3. too tight with the DCS system, coupled.Present equipment management system basically all be " embedded " in the DCS system, be easy to the operation of DCS is impacted, and also strengthened the difficulty of management system installment and debugging.This is to some application scenarios such as this high-risk of thermoelectricity, high emergent industry, and " embedding " equipment management system in the DCS system more or less can increase the potential safety hazard of control system.
4. all be the system of " heavyweight ".Present equipment management system all is powerful and scale also " powerful " basically, and the function of a lot of systems repeats with the function of DCS, more than occurring on the function and not smart situation.
