Abstract
The invention is a small signal line-based multifunctional terminal controller, used in motor vehicle control and industrial control technical range, belonging to the control field, comprising multifunctional control board, small signal transmission line L, and terminal signal decoder, where each soft-touch-nonstick functional key K on the multifunctional control board can generate a separate reference trigger pulse signal which is transmitted through the signal transmission line L to the terminal signal decoder so that the terminal signal decoders decodes the signal into a corresponding action voltage to the function of the functional key K to execute a corresponding action so as to implement load ON and OFF. And the signal transmission only needs a small signal line, saving large numbers of load switches and wires, and the number of functional keys K and terminal signal decoders can be increased at will on the signal line on demand. And it has simple structure, operating simplicity and flexibility and cost far lower than that of the existing CUP control mode.
Description
One technical field:
The invention discloses a kind of small signal-wire multifunction terminal controller, be applied to the device of motor vehicles and Industry Control, belong to field of electric control.
Two technical backgrounds:
Motor vehicles in the past and Industry Control mode have all adopted load switch directly to control topworks and load separately, its shortcoming is: it is oversize, too many to connect up, the size of load switch and lead all will be in the rated current scope, the installation and maintenance difficulty causes after the maintenance particularly that a large amount of leads coagulate disorderly, joint is many, stays potential faults, though CPU control is arranged now, the reference mark still with traditional approach control, can not arbitrarily increase CPU quantity, and cost an arm and a leg.
Three summary of the invention:
Small signal-wire multifunction terminal controller of the present invention, cost is low, and oneself power consumption is little, convenient and flexible operation.
Technical solution of the present invention is as follows: form small signal-wire multifunction terminal controller jointly by multifunctional control board K, signal transmssion line L, terminal signaling demoder.
Multifunctional control board K provides the reference trigger pulse signal to entire decoder, it is function key K that current-limiting resistance R and nonstick button are formed the coding trigger control circuit, current-limiting resistance R resistance is in different size among each function key K, produce different reference trigger pulse signals, produce separately independently reference trigger pulse signal when pressing the benchmark control voltage VD that any one function key K and demoder IC (1) pin send here, this pulse signal is delivered to terminal signaling demoder IC (12) pin through signal transmssion line L.
Terminal signaling demoder, IC have adopted a CMOS decoding device, and each control port can independently use, and has the zero clearing of resetting, latch function.The reference trigger pulse voltage that IC (12) pin receives the transmission of L line is triggered, IC (11) pin produces the moment synchronizing pulse simultaneously, this synchronizing pulse voltage swing, identify work order separately through the IC inner decoding, through the strong corresponding operation voltage of K function of output pin (2,3,4,5,6,7,8,9,10) output and function, carry out corresponding action, the through and off of control load.
Good effect of the present invention is: multifunctional control board K is connected with the terminal signaling demoder only needs a small signal-wire to transmit.The function key K of the identical function on the control panel and terminal decoder IC can increase arbitrarily on signal wire as required, have saved a large amount of on-load switches and lead.Reduced the generation of fault, and wiring is simple, convenient and flexible operation, cost is low.
Four description of drawings:
Fig. 1: be circuit structure schematic diagram of the present invention.
Fig. 2: be circuit theory diagrams of the present invention.
Five embodiments:
In Fig. 2, terminal decoder IC power supply has two groups, and one group provides a basic pulse control voltage VD, IC (1) pin, and another group provides decoder decode voltage VC (14) pin.
Energized moment, the circuit automatic clear resets, and each actuator is in closed condition, and load must not electricity, does not work.Touch the control voltage VD that self-resetting type function key K and IC (1) pin are sent here when pressing on the control panel any one, produce a reference trigger pulse voltage, deliver on IC (12) the pin trigger end through signal wire L, (12) pin obtains a trigger pip, trigger end (12) pin is triggered, IC (11) pin produces the moment synchronizing pulse simultaneously, the size of this pulse voltage is discerned decoding through IC inside, decode work order separately, latch, through output pin (2,3,4,5,6,7,8,9,10) output is with the switching signal control voltage of the corresponding function of function key K, and each output pin is all connecting an actuator, the state of opening of control load.Clicking on the panel same function key K again exports a trigger pulse again and goes out another switching signal through decoder decode, latch, output pin (2,3,4,5,6,7,8,9,10) stops output with the corresponding switching signal voltage of function key K, actuator is in cut-off state, and load must not worked by electricity.
Claims (4)
1, a kind of small signal-wire multifunction terminal controller is characterized in that: multi-functional control panel K, small-signal transmission line L and terminal decoder IC constitute multifunction terminal controller.This controller can increase the function key K and the terminal decoder of identical function, the Push And Release of control load as required arbitrarily on signal wire L.
2, through the described feature of claim (1): multi-functional control panel K is that strong K of function and current-limiting resistance R form the reference trigger pulse generator, current-limiting resistance R resistance is in different size, presses the strong K of any function and just can produce reference trigger pulse signal independently in different size separately.
