One, hardware is formed
1) A/D conversion acceleration signal is after charge amplifier amplifies, again through sending into 8098 ACH after the interface circuit conditioning
7Pin carries out the A/D analogue to digital conversion.8098 chips itself have one 10 A and D converters (ADC) and a sampling holder, so need not to select else the A/D chip.
2) the outer ROM expansion of sheet as the outer read-only memory (ROM) of sheet, is solidified with the Control Software of having finished with the EPROM2764 chip in 2764 chips, and 8098 by reading the content of 2764 chips, operating software, and processing data, call subroutine is realized the control to system.The address space of EPR0M2764 is 2000H～3FFH.2764 chips are electricallyalterablereadonlymemories of a kind of 8k * 8, and among the figure, 13 bit address line A12～A0 are used for address signal line in the sheet, 8 position datawire D7～D0.CF reads to allow signal wire (SW) to be connected with the reading signal lines RD of micro controller system, is used for control data to read.2764 speed are fast, maximum access time 200ns, and 2764 have static wait mode of operation, can reduce function.
3) the outer RAM expansion of sheet is not enough because of 8098 in-to-in ram spaces, behind the connection RAM6264, can constitute a system with larger data storage size, for the computing of program provides the space.6264 is the random access memory of the high integration of 8k * 8.A12～A0 is 13 bit address signal wire (SW)s among the figure, and addressing range is 8k, and D7～D0 is 8 bit data I/O, is connected with 8098 data bus; CE is the chip selection signal line, and signal is produced by address decoder 74L138.WE written allowance signal line with 8098 WR wire joint, is used for the write operation of memory, and OE is for reading to allow signal wire (SW), with 8098 RD wire joint, and the reading of memory.The space address of RAM6264 is 8000H～9FFFH.
4) P
3The reconstruction of mouth adopts 8255 chips to provide scale conversion to P in order to provide drive signal to four stepper motor drivers
3The mouth expansion.D7～D0 data bus and 8098P
3Mouth connects.CS is the chip selection signal line, and RD is the read output signal line, and WR is the write signal line.
Two, circuit working principle
1) P of 8098 micro controller systems
3, P
4EPROM2764 and RAM6264 provide address bus mouthful outside sheet, and P
3Mouth provides data bus again separately, because P
3Mouth is that a bite timesharing is dual-purpose, so be equipped with address latch (74LS373) between micro controller system and memory device;
2) because 2764 and 6264 addressing space is 8KB, so address bus is that 13 A12～A0), wherein A7～A0 is controlled by 74LS373;
3) 0098 micro controller system is to 2764,6265 and 8255 visit, and 74LSi38 provides chip selection signal with address decoder;
When 4) system moved, the CPU of 8098 micro controller systems can only visit whole programs of depositing control system in 2764,2764 in the mode of reading.When carrying out read operation and ale signal and turn to high level by low level, 74LS373 has just had the possibility of latch address, and when ALE became low level again, the address promptly was latched.During the RD=0, the program in 2764 appears on the data bus with the form of binary data.The RD signal is by 0 → 1 o'clock, and data are read by CPU;
5) 8098 micro controller systems adopt quartz crystal to drive oscillation frequency f
Osc=12MHz, period of state T=250ns.
Acceleration pick-up in the data trap with the acceleration signal that collects after the signal amplifier conditioning is amplified, import again in the A/D A and D converter in the central control unit through conversion, filtering, data processing, finally calculate the electric pulse control signal, and control signal sent to stepping motor in the actuating unit, be converted into corresponding angular, to making adjust bar play the effect of damping regulating control.
