But the arithmetic speed that the prior art is utilized the C8051F041 chip has seemed that along with the reliability of Power System Intelligent protection and electrical network develops fast some does not catch up with the needs of present power transformer; 128 * 64 liquid crystal display wherein is less than normal a bit in addition can't show a complete SOE incident; relatively inconvenience of the feasible operation of 2 * 2 keyboard, and autgmentability occasion that can't satisfy some special speed requirement on the low side a bit.
The utility model content
The utility model provides a kind of non electrical quantity microcomputer control device at the prior art above shortcomings, realizes the non electrical quantity protection of transformer, and the computing frequency reaches 4MHz, can respond the fault that power transformer has non electrical quantity to cause fast; Have 5043 chips and can power down preserve the SOE incident; Adopted the keyboard of the full Chinese demonstration of 320 * 240 liquid crystal and 3 * 2 to make operation simpler; Have 8 output relays and can effectively improve stability; Can expand the collection of analog quantity in addition, the utility model adopts the back of the body to insert formula can change mainboard flexibly, reduces the whole table apparatus that causes when certain plate is damaged and all will scrap.
The utility model is achieved through the following technical solutions, the utility model comprises: mainboard, dsp board, power supply, LCD panel and bus board, wherein: bus board is connected with LCD panel, mainboard is connected with dsp board, mainboard links to each other with bus board respectively with power supply, mainboard is connected with bus board, and LCD panel is connected with bus board.
Described mainboard is provided with RS485 controller, relay output interface, non electrical quantity collector and photoelectric isolating circuit.
Described dsp board is provided with TMS320LF2407 chip, 5043 chips and extended menory.
Described mainboard specifically is connected by European slot with bus board.
Described bus board specifically is connected by the 20pin terminal with LCD panel.
Described mainboard specifically is connected by needle-inserted with dsp board.
