Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

Such as Fig. 1-3, the embodiment of the present invention proposes a kind of computer system, including single machine processing system modules, storage mould Block, interface module and voting module；

The storage unit is set in the single machine processing system modules, sees a mouthful dog unit, Interface Expanding unit and data Transmission unit；There are three identical Main Processor Unit, three Main Processor Units are same for the single machine processing system modules setting Work is walked, the respective running that three mutual independent Main Processor Units prevent into them works electric independent of other Main Processor Units Stream and operating voltage are not influenced by other modules.Processor module inside the Main Processor Unit uses STM32F4 module.

Main Processor Unit is all made of commercial component, has the characteristics that high-performance, low cost, low-power consumption, in the present embodiment, As shown in Fig. 2, comprising prefetching, decoding and execute, and having hard floating number using the processor of high-performance three class pipeline mechanism Arithmetic element substantially increases floating point arithmetic rate, and system power frequency is up on 84MHz, in three processor synchronizing processes It would operate in 168MHz, can respond rapidly to and handle various operating conditions.

Memory module is the memory unit of computer system, is mainly used for:

(1) start-up parameter stores, and gapless can work on after guaranteeing system reboot, improves the company of system operation Continuous property, saves unnecessary runing time；

(2) data save and restore, and provide reliable data for fault recovery；Program source code saves, and is single machine generation Code area's failure carries out fault recovery and provides correct program code；

(3) program-controlled file storage guarantees that the outer component that carries is operated according to program, and completion overseas works；

(4) status of equipment stores, so that operator obtains equipment operation information.The storage region, which is that system is shared, deposits Storage area, the storage region of the memory module is system shared memory, read-only using non-volatile band electric erazable programmable Memory EEPROM, model CAT24M01, for the storage of telemetering amount, program storage and stand-by program storage.

The interface module is connect with the single machine processing system modules, and the interface module includes multiple serial line interfaces； It is the bridge of data input, output.It connects and says module and contain the serial line interface of mainstream, such as USART, SPI, I²C、CAN、SDIO Deng and parallel interface, such as FSMC, customized parallel port, most electronic equipment and sensor can be compatible with very well, make Star Service Computer system has more versatility；

System bus is between modules and the bridge of system external data interaction, the selection of bus and designs a calculating machine and is System design initial stage needs one of the important parameter considered.The wherein factors such as the baud rate of bus, transmission mode and compatibility are choosings Select the performance indicator of bus.

In view of the features such as computer is small in size, module is more, data interaction is frequent, can select with bus characteristics I²C, SN and CAN bus:

I²C bus uses both threads cable mouth DA/SCL, and wiring is simple, and transmission rate is up to 100Kbps, can be achieved in bus More holotypes facilitate computer system modules actively to initiate data interaction, and apply in serial total, line digital sensor Extensively, such as PCA9534 (I/O extended chip), HM5883 (Magnetic Sensor).

Spi bus is more using cable resource, and each equipment matches a chip selection signal line, has full-duplex operation, mostly main Mode, easy to operate, message transmission rate is up to 4Mbps, is a kind of high-speed communication bus, but there is also the flow controls that do not specify System, no acknowledgement mechanism are confirmed whether the shortcomings that receiving data.Using extensively on the less bus protocol of module, it is chiefly used in In universal serial bus digital sensor.

CAN bus, bus transfer rate is fast, and 0m length transmission distance can reach 1Mbps, it be based on ICP/IP protocol into The transmission of row data has retransmission mechanism, high reliablity, but CAN bus needs additional CAN controller, is carried out using the bus Data transmit more difficult carry out on-line debugging, using extensively, not being chiefly used in automotive electronics in universal serial bus digital sensor In equipment.

The voting module is connect with the single machine processing system modules, is used for system synchronization, data voting, fault detection With see a mouthful dog logical edit.It is directly related to the real-time and reliability of system.The voting module uses hardware description language Verilog is modeled, and is realized using programmable mouth array module.

The application use Cyclonelv series EP4CE6F17C8, with 6272 logic units, 180 pins and The resources such as 276480 RAM, external 50MHz clock configure FLASH and SDRAM, and the circuit for completing various complexity enough is set Meter.

System is synchronous: it is for eliminating between each isomorphism Main Processor Unit because of the factors such as clock delay and resource mutual exclusion institute Caused by asynchronous degree so that each isomorphism Main Processor Unit is maintained at a phase in operating status, duty cycle and tasks synchronization degree To consistent state.

Fault detection: voting inside modules also set up malfunction monitoring unit, for the ease of the stable of the system, improve The reliability of computer system, the application design error failure monitoring unit, following Fig. 3 design observation circuit, and circuit acquires R₅₉Both ends Voltage, due to R₅₉Resistance value very little be 0.005 Ω, the pressure difference very little at both ends, it is therefore desirable to amplify processing, herein by Difference amplifier exports after its pressure difference is amplified 25 times, obtains the current value on the road, realizes the measurement that voltage turns electric current Mode.

Data voting: by data voting, judge whether the current value monitored produces failure, maintain easily.

Further include energy supply control module, the energy supply control module for control respectively the single machine processing system modules, Power supply in the memory module and described voting this three of module；.

Finally, it should be noted that the foregoing is merely a prefered embodiment of the invention, it is merely to illustrate technical side of the invention Case is not intended to limit the scope of the present invention.It is any modification for being made all within the spirits and principles of the present invention, equivalent Replacement, improvement etc., are included within the scope of protection of the present invention.
