It is embedding in daily life, logistic storage, commerce and trade, industrial and agricultural production activity due to the development of computer technology
Embedded system with its cost is low, small volume, real-time operation, flexible configuration the features such as, obtained increasingly extensive application, and commonly
The multi-job operation of computer is different, and most of embedded systems are all designed to perform a kind of fixed operation, realize a kind of
The function of setting, the embedded system component as built in washing machine are the control operations designed for washing machine, and can not
The control operation of air-conditioning is directly used in, the embedded system component built in oscillograph can not be directly used in projecting apparatus.
Embedded system component generally comprises control unit and execution unit two parts, its existing system structure composed one
As be made up of control unit and execution unit, wherein,
Control unit is the core of embedded system component, completes the work such as identification, control, interaction, management.In existing design
In, it is hard that control unit generally comprises processor MPU, memory, human-computer interaction device, communication and EBI, expansion interface etc.
Part, the software such as bootstrap, operating system, driver built in unit.Externally, by communication and EBI with it is outside other
Equipment calculates part exchange information, and for the control unit comprising human-computer interaction device, operation or manager can pass through man-machine friendship
Mutual equipment input order, parameter, control performs associative operation, and obtains operation execution information by display device；Internally, control
Unit realizes the identification and control to execution unit by expansion interface.
Execution unit is the concrete operations part of embedded system component, under the control of the control unit, specific to perform, be complete
Into corresponding operation.According to the different requirements that performs, execution unit can be designed possess different functions.Such as carry multi-channel A/
D, the execution unit of D/A functions, the execution unit of analog matrix switch is realized, realizes what signal occurred, and decayed, and amplifying, converting
Execution unit, realizes execution unit of Electromechanical Control etc., and different execution units needs different drivers.
Control unit and execution unit are connected with each other by the expansion interface of control unit, and expansion interface is used to realize both
In the connection of signal, control, I/O, power supply etc..
Control unit and execution unit can be designed on one piece of PCB, connected by PCB layout, turn into one it is proprietary
The embedded system component of function（Such as the control unit and execution unit of washing machine）；Control unit and execution unit can also divide
It is not different parts, is connected with each other by forms such as cable, connectors, is combined into an embedded system component（As beaten
The control unit of print machine is arranged at computer terminal, and execution unit is arranged at printer side）.Different execution units needs different
Driver or system software.
It is different parts for control and execution unit, the embedded system being combined each other by cable, connector etc.
System component, under the expansion interface for possessing same specification and definition, control unit can connect different execution units, realize not
Same application requirement.
The software workflow of existing embedded system component is generally：It is electric on embedded system component, it is first carried out controlling
Unit self-test processed, then perform bootstrap and complete real time operating system guiding, into real time operating system, identify holding for access
Row unit, load and execution unit driver, corresponding operating is performed according to the task of setting.In the course of the work, it is embedded
Formula system component can receive to come from live operator or remote control by communication and EBI or human-computer interaction device
Information, order and the parameter at end, and feed back implementation procedure and result.
Then, there is following technical problem in the prior art workflow：
（1）When supporting or connect new execution unit, journey is driven in installation or upgrade-system software is difficult.Due to due to execution unit reality
Existing function difference, each execution unit are required for supporting different driver, in existing implementation, when control unit needs
When connecting, control, driving new execution unit, generally by forms such as network, external memorizers, by new driver
It is installed in control unit system software, or system software is upgraded, becomes and support that the system of new execution unit is soft
Part.The initial initiation of this working method is since computer WINDOWS systems.
But different with conventional computer, many embedded systems are built in device interior, due to system design, installation limitation,
The reasons such as equipment safety, site environment, tend not to connect network or external memory storage, new driver installation is carried out to it
Or upgrade-system software becomes abnormal difficult and complicated, it is often necessary to professional equipment and layman can hardly be carried out, it is no
Then easily the problem of unexpected is brought to cause equipment fault, this make it that the equipment user of built-in embedded system is difficult voluntarily right
Equipment carries out upgrade maintenance, or the execution unit that connection is new.
（2）Safety issue.Journey or upgrade-system software are either driven by network or external memory storage installation, all needed
Reserve custom interface and need corresponding carrier, system is constantly among risk, it is wrong that these risks include installation
Program code, network, virus attack and artificial disturbance etc. by mistake, the stability of this equipment operation to built-in embedded system and
Security causes great hidden danger, and these hidden danger are difficult to find.
If by general standard interfaces such as USB, journey or upgrade-system are driven to install using USB storage, because USB is deposited
The versatility of reservoir, it may access plurality of devices, and its security and contaminated possibility can not all ensure.Such as can be with
The wireless router of remote control, once break through software upgrading interface, it is possible to remote software unconsciously is being carried out to it
Upgrading, so as to cause LAN out of control or information leakage, there is great potential safety hazard.
（3）It is the design of different parts respectively for control unit and execution unit, for continually changing user scene
Demand, new execution unit can be released constantly, and its corresponding driver or system software need to carry out airworthiness compliance, including
Whether meet the control requirement of new execution unit itself, and to announced execution unit control whether to produce it is unpredictable
Influence.
Elapse over time, the execution unit issued listing and used is increasing, and its is soft when new execution unit is released
Part checking workload constantly increases, and it verifies that insufficient risk also increasingly increases.Moreover, because embedded system is most
Complex environment is worked in, these complicated site environments can not be completely reproduced up in laboratory, be caused for soft under complex environment
Part checking can hardly be carried out, the superposition of above-mentioned unfavorable factor so that the work of the equipment of built-in embedded system is uncertain
Also more and more uncontrolled, application risk is constantly cumulative over time.
（4）Limited by cost, power consumption, volume etc., embedded system its control unit internal memory space in sale
It has been fixed that, although leaving certain space surplus in design, as new execution unit is constantly released, it is necessary to constantly install
The new journey or upgrading new system software, its limited space of driving can not meet the needs of this is almost limitless, and this strongly limits user
Using state-of-the-art technology and software upgrading, but if design reserves excessive storage space initial stage and causes cost too high again or power consumption
It is excessive, limit the application of embedded system.
（5）For that can be identified after ensureing new execution unit Access Control unit and normal work, built in embedded system
Real time operating system requirement can support hardware identification, drive journey installation etc. technical protocol, this requires that system possesses higher performance,
More complicated operating system, bigger technical difficulty is also brought to design on hardware and software, cause embedded system material and
Design cost is higher, is unfavorable for marketing.
（6）To meet the different application demand in scene, in same control unit, it may be necessary to carry different real-time
Operating system, to support different execution units, because operating system is built in control unit memory, connecting these needs not
During the execution unit of biconditional operation system, it is required for that whole system software is carried out to replace renewal back and forth, this, which significantly limit, is
The convenience of system application.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of reliability is higher, program code in the absence of setup error,
Network, virus attack and artificial disturbance equivalent risk, the embedded system structure and its method of work of high security；Meanwhile energy
Enough solve when control unit needs to connect, control or drive new execution unit, upgrade maintenance hardly possible is voluntarily carried out to equipment
Problem；It can solve the problem that due to new execution unit increase and cause the embedded system device work for being built-in with control unit unstable
Calmly, the problem of risk is constantly cumulative；It can solve the problem that the insertion due to being built-in with control unit caused by the increasing of execution unit
