Brief description of the drawings
Fig. 1 is the hardware circuit schematic diagram of the present invention.
Fig. 2 is the automatic running program flow chart of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, biological tissue dehydrator intelligence control system hardware by 89C51 single-chip microcomputers, 2864 EEPROM,
27512EPROM, 6264SRAM, ADC0809, MGLS240128T LCD MODULE, input through keyboard circuit and Phototube Coupling electricity
Road etc. forms.
Main control singlechip selects in atmel corp's AT89C51 series monolithics that structure is most compact, volume is minimum
AT89C2051, external 1 2864 is used as program storage, then selects 1 27512 and 1 6264 to be used to deposit debugging routine and fortune
The intermediate data and end product of line program.Liquid crystal display is from built-in T6963C control type MGLS240128T liquid crystal display modes
Block, two kinds of display modes of figure and text are supported, there is 8 bit data bus, 10 control lines and a power line, during connection, single-chip microcomputer
Using data/address bus and control signal, directly using I/O equipment access stencil control liquid crystal display.
According to the functional requirement of system, row decoding is entered using 74LS138 decoders to high 3 of address bus, selects I/O
Mouthful.Input port includes 4 level electrode reading, civil power, the big motor upper limit, big motor lower limit input signals.Level electrode is read at any time
Whether normal detect water level in cylinder；In the case where there is city's electric signal, after big electric motor starting, test battery voltage, which is worked as, is less than threshold value
Storage battery is charged during 25 V.When not having city's electric signal, system is switched to storage battery work, when battery voltage is less than threshold value 23V, then
Battery power is cut off to ensure storage battery not overdischarge；Cylinder position signal is read according to big motor bound, believed when there is big motor lower limit
Number when, send out small machine enabling signal.
Delivery outlet includes battery cell discharge, storage battery charging, heating, Switch for electric fan, water level motor are write, small machine pulse 6 is defeated
Go out signal.Aoxidized to be anti-than level electrode, with software assurance in 1S, 1 subpulse only is sent out to the mouth；To ensure tissue dewatering effect
Fruit, small machine are designed to turn, stop 1min, while when the difference between wax cylinder temperature and preset temperature reaches specified threshold, control
System is heated to be 1min intervals and performed.To improve system rejection to disturbance, prevent program from entering endless loop, we use 14 binary systems
Serial counter 4060 constitutes " house dog ".In normal work, the removing pulse signal cycle that assigns into cyclic program
Property eliminate house dog, WatchDog Timer will not overflow, when system, which is interfered, makes program " run fly ", WatchDog Timer
It cannot in time eliminate and overflow, produce AT89C2051 reset signals, restart system.In addition, in a program, we
RAM is divided into two parts：Run memory and backup of memory.Backup of memory is further divided into 2 areas, when depositing data, by it
Be stored in 3 and be relatively distant from scattered region, establish dual Backup Data.It is interfered in CPU and causes program " disorderly
Fly " when,, also can be immediately using standby after system reset even if the initial data preserved in RAM, mark, variable etc. are destroyed
Part RAM carries out self-test and recovery, ensure that the normal operation of system.
Such as Fig. 2, Control System Software is designed using modular construction and subroutine nesting, by main program, subprogram and in
Disconnected service routine composition.System design is made up of 11 modules, i.e., LOCO modules, main program module, interrupt service module, be automatic
Run module, detection module, programming module, continuously logging modle, operation module, rising module, thermal module, checking module.
Detection：Display detection picture.Temperature signal is taken, is 0 displays temperature short circuit sensor, FFH displays temperature sensors
Open circuit.Power supply voltage signal is taken, overvoltage is shown more than 30V, is shown less than 23V under-voltage.Water level signal is similarly.Start big motor,
If can detect, highest and minimum limit switch display location switch are normal.Major function is each needed for detection tissue dewatering
Whether controlled quentity controlled variable is normal.
Programming：Display programming picture, by being set to the upper and lower judgement of key assignments into certain set program, then judge key assignments,
Left-right key control cursor is moved left and right, and upper and lower key logarithm value is added and subtracted, and determination key then accesses data while returns to main menu.
Because the liquid crystal display is only able to display 7 style of writing words 1 time, when being modified to 5 cylinder, screen can roll.At this moment, last is first copied
OK, then wiped, be further filled with next line, last whole screen is shown.Major function is to allow needs of the user according to tissue dewatering
The time control of preset 4 sets of programs.
Continuous operation：Start big motor, machine is continuously run, and can be stopped in any cylinder position, when detecting that cylinder position signal is
When 12 cylinders, limit signal are the upper limits, continuous operation is eventually.
Rise：Display rises picture.Start big motor, when position switch signal is highest order and cylinder position signal is 12 cylinders
When, stop than big motor.When judging that key assignments is to determine, the parameters in programming are taken to turn automatic running.For when machine is any
During position, hanging basket is risen；In 12 cylinder, hanging basket is taken away;When operating personnel inspect periodically to machine, start big motor.
Whole programs compile debugging under Keil C51 environment and passed through.A function, its reference are called in wherein all displays
The instruction system of T6963 C LCD MODULEs is write.
