High performance embedded system generally comprises man-machine interactive system, arithmetic processing system and control (comprising signals collecting) system three parts.The application high speed microprocessor of general high performance system carries out calculation process as core and connects mutual and control peripheral components, microcontroller with in addition both can be directly actuated mode (being that a microcontroller works in system in theory) wherein, also can be indirect mode, microcontroller by other microprocessor controls another both.In front a kind of mode, microprocessor is directly connected with peripherals, and equipment is controlled peripheral hardware by microcontroller hardware operation, and code is all in the program of microprocessor.In the second way, need to design the program of peripheral microcontroller and the logic connected mode of each processor controller, microprocessor is responsible for providing control signal, microcontroller concrete operations peripherals.
In such scheme, generally can complete design task, but all there is obvious shortcoming: first kind of way consumption is compared with resources such as the GPIO mouth of multimicroprocessor, system times, and microprocessor work is easily interfered.Simultaneity factor circuit design is very complicated, and system power dissipation is very large.Second way design is complicated, and a lot of programs need to be understood the use of each peripheral microcontroller and need to be familiar with each peripheral hardware, and simultaneously such design logic is very complicated, easily occurs mistake.
Summary of the invention
The object of the present invention is to provide a kind of control interactive system relay and control card, this control card can with the high performance embedded system interface of main flow, by development library and primary system program, carry out unitized overall development, jointly realize systemic-function, thereby make up the defect of high-performance processor on system is controlled or reduce the complicacy of multilevel system.
To achieve these goals, technical scheme of the present invention is as follows.
A kind of control interactive system relay and control card, use USB (universal serial bus) and high performance embedded system primary processor and microprocessor communication, the program that the program code of equipment is fixedly accepted higher level's microprocessor signals and made a response, equipment is furnished with a development library that includes serial port drive information and control signal message.Like this, when exploitation microcontroller relative program, main microprocessor program and this equipment card program can be used as to an integral body develops.
Described control signal is the fixing packet of form, carries following information: the address (or title) of the explanation of action type, the register that will control, the operation instructions of wanting this register to carry out, operate fixedly beginning and the trailer field of relevant operand, message to this.Wherein, being illustrated as of described action type read a certain register data and by the universal serial bus value of beaming back or revise the value of a certain register.The described operation instructions that register is carried out comprise read, write, compare, revise a part wherein one or more.The operand that described operation is relevant is to want the data that write or want cumulative data.
The said equipment workflow is: during high-performance microprocessor program development, use the development library of this coordinative composition of equipments, development library provides the method for using serial bus interface to send packet, and required information and the method for generated data bag; When high-performance microprocessor program is controlled this equipment in work to needs, first the packet that calling data bag generation method and Information generation need to send, after packet generates, use method that serial bus interface sends packet by Packet Generation to this equipment, this equipment is analyzed its correctness after receiving packet, for correct under normal circumstances this equipment of packet, the requirement according in packet is carried out to work, after having worked, return to as requested settling signal or the required data of higher level's high-performance microcontroller.
In above-mentioned control card, primary processor is ARM7, ARM9, ARM11, ARM Cortex-A, ARM Cortex-R Series of MCU, and wherein ARM Cortex-R series processors adopts its high-performance part; Microprocessor is any one microcontroller in ARM, AVR, 80C51, STM8 kernel.
This beneficial effect of the invention is:
(1) the separated exploitation of hardware driving layer and the exploitation of software algorithm layer of embedded system, can Speeding up development speed, make embedded device system level clearer and more definite, more easily design is a kind of new method that shortens the construction cycle, reduces development difficulty of bringing to large-scale, complex embedded system design field.
(2) only need be on high-performance microprocessor coding, but can use the resource on high-performance microprocessor and this equipment simultaneously, in the situation that not increasing system development complexity, can, in conjunction with strong, the resourceful advantage of microprocessor controls ability on high-performance microprocessor fast operation and this equipment, make entire system can evade high-performance microprocessor in conventional scheme simultaneously and drive bottom hardware easily to occur disturbing and unsettled problem.The large-scale embedded system of design can provide better serviceability in fields such as commercial unit, national defense applications, scientific research instrument like this.
(3) use the mode of serial bus communication to work, host computer can be not only the embedded system of being furnished with high-performance microprocessor, can be also general computer system, and a system can be equipped with a plurality of equipment and not change original software configuration.That such change makes is large-scale, complex embedded system can allow stronger data-handling capacity and control ability, also make embedded system development more towards programmed algorithm, and less control bottom, thereby increased development mode, made more technician can enter the work of embedded development field.
Accompanying drawing explanation
Fig. 1 is the implementation process functional block diagram of control card in the embodiment of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described, to better understand the present invention.
Embodiment
Specifically take and use the technical program to complete apparatus for production line control system as example.The design objective of system is to use an overhead control embedded system to control a plurality of electromechanical equipments and signal detection apparatus on a production line, system according to workman's operation open, stop, the basic operation such as reset, operating room's system judges according to the signal of signal detection apparatus monitoring, thereby control electromechanical equipment work, completes production.
A kind of control interactive system relay and control card, system hardware forms: (1) using the master system that high speed microprocessor is core: use Samsung ARM116430 microprocessor as central processing unit, processor drives signal by serial ports (USART serial ports 1,2,3,4) output drive signal, this part is equipped with VGA and drives chip on VGA display, to show output, connects USB keyboard input by usb bus.(2) take the driving chip that STM32F103ZET6 microcontroller is each equipment.
