Along with the growth requirement of electric intelligent, the application of microcomputer excitation in power station is more and more extensive, and microcomputer excitation system is mostly use high-performance microprocessor to be core, with high integrated chip group for main control chip, and arithmetic speed develop rapidly.Early than nineteen sixty-five, Moore's Law is just pointed out: the number of circuit integrated in integrated circuit (IC) chip, just doubles every 18 months.The renewal of the technology of visible integrated circuit and upgrading are changes with rapid changepl. never-ending changes and improvements, and excitation product producer in the market replaces a whole set of excitation product often, also the good product that does of some compatibility, be that whole regulator is upgraded (namely unifying from the bus board of regulator to adjustable plate to change), realize the update of excitation product.Meanwhile, national grid proposes intelligentized requirement to excitation system, and this is just to many old power stations, and uses the power station of low side microcomputer excitation system to propose mandatory order, and upgrade the requirement that is also inevitable.And these the traditional update modes above mentioned, need the scope of replacing large, the working time is longer, also will drop into a large amount of technician to carry out work simultaneously, has both taken time and effort, again cost gold, brings extra economic loss to user.For the unit of a more switching regulator; need technician about two to three; about one week of subsistence level consuming time; for the unit of a 10000KW; the loss of shutting down a week is about 500,000 yuan; personnel's wage expense and cost of products are about 50,000 yuan, then user is to the cost accounting about 550,000 yuan of the more capable update of field regulator.
Existing all buses do not support double governor structure, current two or multi-regulator control system, the control to same control object all can only be realized by the switch unit installing multi-regulator passage in bus outside additional, the system combined like this, one is very huge and complicated, and reliability is difficult to improve; Two is that high, the difficulty of cost safeguarded wants large; Three is the upgradings being unfavorable for system, and the cost of upgrading is high, the cycle is long, does not catch up with the speed of development of electronic technology and the needs of practice use.
Summary of the invention
For the problems referred to above, patent of the present invention provides the bus type array mode (can be arbitrarily made with: " microcomputer+microcomputer ", " microcomputer+simulation ", " simulate+simulate " mode) of a kind of microcomputer and simulated dual passages regulate device and implementation method of upgrading, enormously simplify system architecture, support binary channels field regulator structure, reduce the cost of upgrading.
Technical scheme of the present invention: the bus-organization of a kind of microcomputer and simulated dual passages regulate device and implementation method of upgrading, is characterized in that, comprise the following steps:
1) main control chip is arranged on adjustable plate, the peripheral interface of unified definition bus and adjustable plate;
2) analog board and the unification of microcomputer plate are connected on bus board by DIN connector;
3) switch unit of mimic control panel and computer control board and signal shutoff unit are all designed on bus board, control to switch by software and hardware and shutoff performs switching and the signal shutoff that chip realizes analog board and microcomputer plate;
4) analog board and microcomputer plate is selected to carry out combination in any or upgrading, to realize combination or the upgrading of microcomputer and simulated dual passages regulate device as required respectively.
Described DIN connector can realize the plug of analog board or microcomputer plate.
Described switching and shutoff perform chip and adopt STC2052 chip.
Technique effect of the present invention: not only support that two microcomputer based regulator passage also supports microcomputer to add simulation, simulation adds simulated dual regulator channel structure.The combination of regulator and upgrading are designed in plate one-level, adopts self-defined bus formula board plug structure, realize the compatibility of dissimilar, different class excitation con-trol plate, exchange and upgrade function first.Enormously simplify system architecture, it is synchronous that energy maintenance and microprocessor upgrade, maintenance cost is low, solve the weak point of existing hyperchannel regulator preferably, in actual use, the technical interface of energy specification microcomputer excitation regulator, accelerates research and development process, reduces R&D costs in this invention, the cost renovating and upgrade of user can be reduced again, the stability popularized, improve a power supply quality and electric system accelerating microcomputer excitation is had great significance.
