Technical field:
The present invention relates to electricity field, particularly relate to the expansion technique of functional module in embedded system, particularly a kind of embedded system function expanding module automatic identifying method.
Background technology:
The commonly used integrated mode of industrial technology system, the quick upgrading ability of its system requirements, the Quick Extended of systemic-function is particularly important.In prior art, it is internal that expansion module is arranged on embedded host (or instrument), delivers with embedded host (or instrument), and later maintenance is inconvenient；If expansion module needs specifying position to install when main frame (or instrument) outside extension, if wrongly installed, it be likely to occur unrepairable and damage, and the quantity of a certain functional module is required；User needs to be configured by button or alternate manner on main frame (or instrument), informs the type of modules that main frame (or instrument) is installed, uses inconvenience.
Summary of the invention:
It is an object of the invention to provide a kind of embedded system function expanding module automatic identifying method, the technical problem of embedded host expansion module inconvenient operation in described this embedded system function expanding module automatic identifying method prior art to be solved.
nullThis embedded system function expanding module automatic identifying method of the present invention，Including a process that expansion module and main frame (or instrument) are attached，Wherein，One the first single-chip microcomputer is set in main frame (or instrument)，One second singlechip is set in expansion module，The first described single-chip microcomputer and second singlechip each include communication interface，Described expansion module and main frame (or instrument) are attached during，The communication interface of the first single-chip microcomputer and the communication interface of second singlechip are connected，Main frame (or instrument) is utilized to send inquiry command by the first single-chip microcomputer to second singlechip timesharing，Second singlechip passes through the first single-chip microcomputer after receiving inquiry command and returns the description data of self to main frame (or instrument)，Described description data include the expansion module title at self place、Expansion module function and expansion module input/output information，The description data returned are processed by main frame (or instrument).
Further, corresponding expansion module need to carry out parameter arrange time, add in main frame (or instrument) and interface be set.
Further, utilize main frame (or instrument) periodically to carry out data communication to expansion module, send data or gather data.
The present invention compares with prior art, and its effect is positive and obvious.The present invention is by separately installed with main frame (or instrument) for expansion module, in main frame (or instrument) neutralizes expansion module, single-chip microcomputer is each set, the communication between single-chip microcomputer is utilized to realize main frame (or instrument) to expansion module function and the automatic identification of parameter, therefore its function can be identified when expansion module is installed at an arbitrary position, the later stage achieving expansion module installs, and facilitates the later stage function upgrading of client.
Accompanying drawing illustrates:

Detailed description of the invention:
Embodiment 1:
nullSuch as Fig. 1、Shown in Fig. 2 and Fig. 3，The embedded system function expanding module automatic identifying method of the present invention，Including a process that expansion module and main frame (or instrument) are attached，Wherein，One the first single-chip microcomputer is set in main frame (or instrument)，One second singlechip is set in expansion module，The first described single-chip microcomputer and second singlechip each include communication interface，Described expansion module and main frame (or instrument) are attached during，The communication interface of the first single-chip microcomputer and the communication interface of second singlechip are connected，Main frame (or instrument) is utilized to send inquiry command by the first single-chip microcomputer to second singlechip timesharing，Second singlechip passes through the first single-chip microcomputer after receiving inquiry command and returns the description data of self to main frame (or instrument)，Described description data include the expansion module title at self place、Expansion module function and expansion module input/output information，The description data returned are processed by main frame (or instrument).
Further, corresponding expansion module need to carry out parameter arrange time, add in main frame (or instrument) and interface be set.
Further, utilize main frame (or instrument) periodically to carry out data communication to expansion module, send data or gather data.
Concrete, as it is shown in figure 1, module 1 to module n is connected with the microcontroller of main frame (or instrument) by UART communication interface.The power supply of module is provided by main frame (or instrument).Main frame (or instrument) and expansion module can carry out the data interaction on software by communication interface.For the protection to module, when installing expansion module to main frame (or instrument), need to disconnect the accessory power supply of main frame (or instrument), module is installed afterwards, when main frame (or instrument) is initially powered, main frame (or instrument) is to the transmission inquiry command of module timesharing, the module receiving order returns the associated description of self to main frame (or instrument), including module name, functions of modules, the information such as module input and output, aft engine (or instrument) be handled differently by these module informations received, if respective modules needs to carry out parameter setting, main frame (or instrument) needs interpolation to arrange interface.Main frame (or instrument) periodically can carry out data communication to module, sends data or gathers data.
The relevant information of main frame (or instrument) inquiry module, if respective modules interface is without information answer within the time of regulation, then it is assumed that this module interface does not installs module, does not deals with.
Fig. 2 and Fig. 3 is the example that expansion module installs to main frame (or instrument), numbering 20 is main frame (or instrument), numbering 10,12,13,14 is expansion module, functional requirement according to main frame (or instrument), several module interface can be opened, in this example open 4,4 modules can be installed in main frame (or instrument) simultaneously, and order no requirement (NR), position no requirement (NR).
Below preferred embodiment to the invention is illustrated, but the present invention is not limited to embodiment, those of ordinary skill in the art also can make modification or the replacement of all equivalents on the premise of the invention spirit, and modification or the replacement of these equivalents are all contained in scope of the present application.
