Description

The intelligent computer controller

The utility model relates to a kind of intelligent computer controller, belongs to a kind of micro computer automaton.

Along with the development and progress of epoch new science and technology, people are thirsting for the automatic machinery people and are helping people's management and operation routine matter.As: the automatic demonstration of temperature, the mensuration of gasoline quality and quantity, fluid drive, the automatic detection of automatic driving and internal fault all can realize intelligent computer control.It is former that what mostly adopt is the control mode of mechanical type and general electronic type, to alleviate heavy manually-operated, enhance productivity, guarantee product quality, but these devices are often existing following weak point in varying degrees: volume is big, and control reliability is poor automatically, the little precision of range of control is low, the cost of manufacture height, maintenance load is big, lack of wisdom.

The purpose of this utility model just is to provide a kind of intelligent computer controller with multiple automatic control function, and can set control standard edit routine arbitrarily according to user's specific (special) requirements and realize Based Intelligent Control.

For achieving the above object, the utility model can be realized by following scheme: its composition is connected and composed by wire harness by central data treatment circuit, display circuit, data acquisition circuit, performance element control circuit and power circuit: the central data treatment circuit is to be made of single-chip microcomputer U1, crystal oscillator C4 and peripheral cell; Data acquisition circuit is to be connected to form by divider U5 and physical quantity probe interface XS1, XS2, XS3 and thin film switch keyboard interface XS4; Display circuit is to promote display T1, T2 by code translator U2 and bus driver U7 to carry out the physical quantity demonstration; The performance element control circuit is to be made of bidirectional triode thyristor T4-T9 and actuator interface S1-S6 that reverse driven U4 reaches by reverse driven U4 control.

The utility model has the advantages that: volume is little, and cost is low, and is easy to install and use, intuitive display, and automatic control accuracy height, control reliability is strong, and is with high content of technology and have intelligent.

The drawing explanation:

Accompanying drawing is the utility model electrical schematic diagram.

Now in conjunction with a specific embodiment the utility model is described in further detail: the intelligent computer controller is by central data treatment circuit (1), display circuit (5), data acquisition circuit (2), performance element control circuit (4) and power circuit (3) connect and compose by power lead and wire harness, central data treatment circuit (1) is by the single-chip microcomputer U1 of 18 pins (Z86E03AH DIP18), crystal oscillator C4 and peripheral cell constitute, at 15 of single-chip microcomputer U1,16 pins are to being connected to capacitor C 6 between the ground respectively, C5, at 15 pins of single-chip microcomputer U1 to being in series with crystal oscillator C4 and resistance R 11 between the power supply successively, at 18 pins to being parallel with resistance R 2 and capacitor C 3 between the ground; Data acquisition circuit (2) is to select 13,14,15,12 pins of a divider U5 (4051 type) to be connected successively with 1,2,3,4 pins of thin film switch keyboard interface XS4 by eight, select being wired to of a divider U5 and thin film switch keyboard interface XS4 to be connected to resistance R 6, R7, R8, R9 between the power supply successively eight, the end and eight of physical quantity probe interface XS1, XS2, XS3 selects 5,2,4 pins among the divider U5 to be connected successively, and the other end is connected with power supply; Display circuit (5) is to promote 47 n segment display n T1, T2 by code translator U2 (74C154) and bus driver U7 (74LS244) to carry out the digital demonstration of physical quantity; Performance element control circuit (4) is by reverse driven U4 (74LS366); bidirectional triode thyristor T4-T9 (3CTS) and actuator interface S1-S6 constitute; bidirectional triode thyristor T4-T9 and actuator interface S1-S6 are together in series and two terminate on the AC power; on ac input circuit, be in series with a quick protective resistance U3 (470 class); protection controlled electric appliance when external voltage is too high, 3 of the control utmost point of bidirectional triode thyristor T4-T9 and reverse driven U4; 5; 7; 9; 11; 13 pins be connected by single-chip microcomputer U1 instruction control reverse driven U4 make its be output as high voltage from but the bidirectional triode thyristor conducting reaches the purpose of control apparatus work.Power circuit (3) is made up of 220V alternating current input power supplying interface XS5, power transformer T3, full-bridge rectifier B1, three terminal regulator U6 (7805 type), voltage stabilizing diode Z1 and filter capacitor C2, C8, and output 5V DC voltage is for each integrated circuit work.Full-bridge rectifier B1 be parallel with filter capacitor C7, C11 and divider resistance R1, R3 by ground between three terminal regulator U6 links to each other, the junction output dc voltage by divider resistance R1, R3 selects a divider U5 to use for eight.Be used for freezer as the utility model and carry out Based Intelligent Control.The physical quantity detecting element is inserted freezer sample and insert among physical quantity probe interface XS1, XS2, the XS3, keyboard is connected on the thin film switch keyboard interface XS4, and the compressor power in the freezer is connected on actuator interface S1-S6 two ends.The divider U5 that the data of freezer enter in the data acquisition circuit (2) measures collection to the physical quantity that will measure, then the data of gathering are delivered to the temperature that central data treatment circuit (1) carries out data operation, analysis and shows freezer by display circuit (5), then by the conducting of the reverse driven U4 in the performance element control circuit (4) control bidirectional triode thyristor T4-T9 with end, reach opening and closing of control refrigeration motor.Change the temperature parameter of freezer as needs, can import new instruction, and select a divider U5 through eight, keyboard action information is sent to central data treatment circuit (1) handle, thereby realize the change of working status parameter by keyboard.
