Description of drawings
Fig. 1 is the utility model chassis registering instrument circuit structure principle schematic.
Embodiment
In the chassis registering instrument of the real-time collection vehicle chassis information that Fig. 1 describes, a real time clock circuit that links to each other with vehicle power is arranged, the optocoupler amplitude limit A/D converter that watchdog circuit is connected with the vehicle chassis sensor electrical.Real time clock circuit is made up of two crystal oscillators and capacitor, for single-chip microcomputer provides system clock and RTC clock; Watchdog circuit is made up of X5043S8I integrated circuit and resistance, electric capacity and diode; Optocoupler amplitude limit A/D converter is made up of MCP32-8 integrated circuit, TLP521 integrated circuit, resistance, electric capacity, diode etc., and it is the processing of digital signal that the isolation processing of realization paired pulses input signal reaches analog signal conversion.As CPU, SCM program adopts the C language through 32 high-performance single-chip microcomputers.PC end Control Software adopts VC++6.0 to write.32 high-performance single-chip microcomputers link to each other ferroelectric memory and Flash storer, working hours and the distance travelled record of ferroelectric memory store car every day, the data that preservation need on-the-fly modify.The duty and the sensor information of jumbo Flash memory storage vehicle chassis.The USB flash disk controller is realized the reading and writing data of USB flash disk, and communicates through continuous PC computing machine of USB connecting line and PC computer management software.Adopt the inner USB interface of 32 single-chip microcomputers, realize the related protocol and the device description of communicating by letter of PC computing machine and USB device and HID equipment class through programming.Registering instrument inserts computing machine as the moving HID equipment of a free drive, has solved the problem of registering instrument and computing machine usb communication.USB flash disk can adopt domestic mature technology to stablize the managing chip of CH376 as USB flash disk.Two independent the one CAN bus 1 connects the dress registering instrument through optical coupling isolation circuit respectively mutually with the 2nd CAN bus 2.32 Control Software parts that the high-performance single-chip microcomputer is held through PC; The actual motion state of control in real time and management current time vehicle; Accomplish the signals collecting of each sensor of vehicle chassis, the data of gathering sent to through the CAN bus adorn registering instrument; The result who gathers reflects the actual motion state of current time vehicle, and registering instrument adds up vehicle working time every day and distance travelled, and the result is saved in the storer.Through USB flash disk data download through mandate (binding).Managerial personnel can control and management accounts through the Control Software of PC end in real time.
The connection of USB system and the key of management are to prevent the illegal copies of chassis-date; The keeper is through binding USB flash disk to registering instrument; Thereby allow the chassis-date of USB flash disk Download History appearance, the keeper can irregularly change the password of oneself through the Control Software of PC end simultaneously; Because administrator password is related with the USB flash disk down operation, more flexibly the illegal copies of protected data.
In storer family, ferroelectric memory has does not have the read-write time-delay, and time data memory reaches the good characteristic in 10 years.
