[accompanying drawing explanation]
Fig. 1 is automobile electronic modular of the present invention exploitation hardware platform block diagram.
[embodiment]
Below in conjunction with accompanying drawing, the present invention is described in further detail:
See Fig. 1, a kind of automobile electronic modular exploitation hardware platform, be one based on the modularized hardware development environment under Infineon XC2000 family chip (complete series is compatible).Comprise the multiple functional module group for automobile electronic modular hardware development and middle control central module, described multiple functional module group is connected by standard interface with middle control central module; Described functional module group be furnished be suitable for Vehicular system protection, coupling, debug circuit, docked in hot plug mode by standard interface between described functional module group; Described multiple functional module group comprise CAN, SPI communication module, serial communication module, ADC module, driver module, IO input/output module and power module.By being furnished with the peripheral resource circuit of standard, each module is organically integrated into variable platform compounds instrument.Thus realize under a platform according to project and actual needs, change hardware configuration flexibly, be aided with software, with in the shortest time meet exploitation checking demand.Such design can reduce the number of times repeatedly verified to a great extent, reduces error rate, improves development efficiency.
On Resourse Distribute: all functions of middle control central module are all furnished with standardized program, developer can quick calling standard program function, does upper layer application exploitation.Modular function library can cutting flexibly, can reduce system resource overhead.Middle control central module is provided with the interface that two-way freely can configure communication mode, baud rate, data lattice etc., and the circuit in CAN is furnished with signal conversion transceiver, protection circuit, traffic load pilot lamp.Different baud rate can be distributed so simultaneously, be enough in exploitation CAN webmaster application to facilitate.
Middle control central module arranges two-way SPI communication interface, and SPI communication module is reserved standard 4 line communication interface externally, and leaves in automotive electronics hardware design and commonly use SOP-8 and encapsulate and periphery configure circuit.Can verify the equipment that multiple SPI communicates like this, because SPI inherently can time-sharing operation, even if so a road SPI also can meet many equipment use, multichannel design is in order to verification system more comprehensively and provides resource reservation.
Middle control central module arranges two-way serial communication interface, and serial communication module has the various configurations such as RS232, RS485 optional, meets various communication standard and uses.Serial communication module two road port, one group can be realized like this and receive data, send out data for one group, because serial communication can not communicate by group communication looped network simultaneously, so the design of two-way serial communication just can internal system by one receive one with other system between form serial ports looped network, send and receive messages in the mode of token.
Middle control central module arranges 8 road analog acquisition interfaces, and ADC module for automotive electronics general purpose transducer signal, has the functions such as signal filtering, conditioning, protection by peripheral circuit.Each ADC module only for a road signal transacting, each other without interruption, can simultaneously for the analog input signal that maximum 8 tunnels are dissimilar.
Middle control central module arranges 6 road PWM adjustable interfaces, and driver module configuration automotive electronics high frequency, big current metal-oxide-semiconductor do secondary drive, and can feed back size of current when driving load.6 roads drive and can be used alone, drived control topworks, also can cascade use.Driving circuit uses PWM, and type of drive is flexible.The design that 6 roads drive also can meet user demand in driving at the motor of complexity.
Middle control central module arranges 16 road IO IO interface.IO input/output module is done with isolation processing by photoelectric isolated chip to outside input, outside input is played a protective role while completing level conversion, prevents external disturbance influential system.IO input/output module has single channel, two-way, four tunnels optional, can use by independent assortment.And the standard interface of the above-mentioned all modules of this platform all can be used as input/output port and uses, as its certain module in project is asked does not need whole use, and all can use when input and output are not enough.CAN communication before, SPI communicates, serial communication, and ADC and the port in driving can be multiplexed with IO input and output.First abundant IO port can meet the processing demands of various types of signal amount to the full extent, and at the beginning of exploitation, various I/O port secondly just can be utilized to export as feedback, this is significant for the software development on hardware.
Power module has comparatively wide operating voltage range, is 10-60V, and this wide-range power modulation can meet vehicle from 12V to 24V, the even demand of 48V system comprehensively.Power module driving force is 3A, can meet this platform and normally use at full capacity time, can ensure all peripheral modules simultaneously connecting system time can steady operation, do not limit by power supply.And having stronger anti-interference, protecting against shock ability, has short circuit overload protection.
Each functional module is furnished with driver and the interface interchange function of its correspondence, separate between each driver of modules and interface interchange function.According to actual items needs, first each module spliced can be connected into the hardware platform that project needs, add ready-made driver module when bottom layer driving configures, complete the bottom configuration effort of platform.The interface function in middle layer being added in project procedure when calling each module drive simultaneously, if need when doing upper layer application can call each functions of modules flexibly by interface function, or changing each module work pattern.Also analog acquisition amount or control port output level can be read by interface function.During for new projects or hardware change, bottom layer driving, middle layer function interface all can not change, reduce development amount and cycle, only need hardware increases and decreases several groups of modules, the corresponding program of the corresponding increase and decrease of bottom layer driving, upper layer application makes corresponding adjustment.
The principle of the invention is: the thinking of global design in the design of original automotive electronics broken the whole up into parts, and a complete hardware environment is split as multiple standard module, separate between module, is coordinated to work between each module by main control module.The mode of being docked by each module interface of standardization and primary module realizes communicating between master control with each module, and then co-ordination.An integral platform is become again from independent individual one by one.First must according to the actual demand of automotive electronics by CAN, SPI communication module, serial communication module, ADC changes peripheral module, IO input/output module, and drive circuit module and power module design separately, externally carry out signal transacting and protected working, internally can free communication, and can plug flexibly, independent assortment.Mutually can not interfere because of profile when changing peripheral module simultaneously.
Above content is in conjunction with concrete preferred implementation further description made for the present invention; can not assert that the specific embodiment of the present invention is only limitted to this; for general technical staff of the technical field of the invention; under the prerequisite of not isolating the present invention's design; some simple deduction or replace can also be made, all should be considered as belonging to the present invention by submitted to claims determination scope of patent protection.
