MCS-96 based on speed detection indicator

Speed. Automatically switch the appropriate test methods. Even if a large speed range, because of the automatic time switch testing methods. Therefore, the instantaneous speed can be dynamically displayed in real time, and maintain a fairly high accuracy. 3 System block diagram system block diagram shown in Figure 4. After the pulse sensor output signal to the jitter and interference rejection, by the HSI. 1-channel input 8798 microcontroller. To ensure accurate counting. Monitor access to data from the serial port, serial port is set to mode 0. Flash memory is used to store a maximum speed of traffic and some special parameters for vehicle maintenance and failure analysis. 8798 contains its own internal watchdog circuit functions. P4, P1 for the address bus, doubles as a data bus, access to flash memory. TXD =: {Gen suck RXD8798 shaping circuit BU HSI. I a P. U Figure 44 block diagram of the software process consists of 4 modules: test module, operation module, display module and storage module. Test module contains several interrupt handlers. Operation module calculated according to the type of speed testing methods. The module includes numeric conversion routines and arithmetic routines. Dynamic scanning display speed display module, the decimal point can float, if the display uses three shows range from 0.01 to 999, shown in Figure 5. Figure 5 shows part of the program given below is as follows: aIRG0007HLIMPSTARTPROClg ~ A ~ TIONII ~ TRUMENTATION,[link widoczny dla zalogowanych], Voi. 25, No. 7, J word. ,[link widoczny dla zalogowanych], 20O4 products, intelligent process control instrument Pan Jianbin drying.

If a reasonable expansion of the system, but also other parts of the car to detect and control,[link widoczny dla zalogowanych], such as car air-conditioning, fuel systems, engines and even cars, domestic cars can have better performance, to digital forward.
