Description
Technical field
The invention belongs to field bus device administrative skill field, relate to a kind of field bus device monitoring management system.
Background technology
From the eighties in 20th century, fieldbus because its reliability is strong, communication is quick, compatible wide, cost is low etc., and a series of advantages are able to widespread use in industrial automatic control.Increasingly automated, the digitizing 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 meet the needs of various industries.But also there are some very important problems in current most of equipment management systems.
Along with the development of fieldbus, You Duo company has developed equipment management system separately according to the requirement in market at present, and has obtained a large amount of application, and 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 module composition wherein and the information interaction of field apparatus and equipment management system, and the two is all mutually different.Just because of its mechanism difference, the application of two kind equipment management systems is also differed widely.
1) Simatic PDM system
Simatic PDM is a set of equipment management system developing for Profibus field bus system.This cover system be one for field apparatus and automation component are shown, 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 by field devices integration.In this cover system, allow to realize integrated by multiple method; By device fabrication business's DD; By agreement PROFIBUS PA-Profile V3.0; By 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 are all that the form with functional block realizes in equipment, and the information such as messaging parameter, device parameter, argument structure and the device action of equipment all offers the system integration user of equipment by EDD file simultaneously.PDM has a top-heavy system architecture.It is very high to the requirement of equipment manufacturers, needs equipment manufacturers in production equipment, just consider the management work such as maintenance, optimization to equipment and realize in equipment with the form of functional block.
By use EDD file realizes integration of equipments theoretical method at client layer to equipment based on the not requirement of which kind of field bus protocol, therefore use the PDM system of this theoretical method very extensive at usability.But also just because of this theoretical method, PDM has a strict requirement to equipment, and field apparatus must provide EDD file, for the field apparatus of not supporting EDD, this cover management system is inapplicable; Simultaneously because the groundwork of this devices in system management is all to realize in equipment by the form of functional block, require very high to device fabrication business, the function that therefore can realize is fairly simple, limited, and the management function of the increase that the user of equipment also substantially can not be extra to 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, cannot be general with all devices outside, PDM diagnoses mainly for equipment and adds up, and for the rig-site utilization management aspect function of this specific industry of power plant a little less than, cannot in the time that need to safeguarding, equipment failure appearance or equipment provide corresponding maintenance guidance, can not automatically generate maintenance or maintenance work ticket, the fault 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 completely to the historical data of whole field bus device, although PDM can generate alarm log, and preserve with CSV form, but when PDM computing machine when breaking down and restarting, in the time 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.Can realize the functions such as the management of intelligent instrument valve arrangement, capability of engineering equipment monitoring, process device Performance Detection and system protection by the integrated application of above-mentioned five systems.
Wherein, AMS equipment management system is from the angle of the system integration, and user's requirement modularize has further been formed independently to management system and unified to be integrated on an information platform.The advantage of this system is: the parameter information of all field apparatuss is all embodied in a unified interface; In the time carrying out a certain function, 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 equipment by traffic pilot and DCS system simultaneously, so just cause equipment to add more complicated, had a strong impact on the extendability of system.
Summing up above two kinds of conventional equipment management systems can find out, the equipment management system of main flow has several defects at present:
1. pair equipment requirement is high.Most of equipment management systems all require equipment must be able to provide facility information file as the EDD file of PDM, the DD file of AMS.Therefore, when system operation, require equipment must be able to generate, provide corresponding facility information file, must improve like this requirement to equipment, once equipment cannot provide message file, management system cannot be brought this equipment into management area, has reduced versatility.
2. extendability is poor.Most of equipment management systems all will communicate with equipment, therefore 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 complicacy also will inevitably have influence on original DCS system.
3. too tight with DCS system, coupled.Current equipment management system be all substantially " embedded " in DCS system, be easy to the operation of DCS to impact, and also strengthened the difficulty of management system installment and debugging.This is to some application scenarios high-risk as this in thermoelectricity, high emergent industry, and " embedding " equipment management system in DCS system more or less can increase the potential safety hazard of control system.
4. be all the system of " heavyweight ".Current equipment management system is all powerful and also " powerful " of scale substantially, and a lot of functions of system repeat with the function of DCS, more than occurring in function and not smart situation.
