(2) as shown in Figure 2, micro-kernel need offer the unified registration interface of each assembly, and the registration interface function that assembly uses micro-kernel to provide is finished the registration of assembly function at micro-kernel according to step (4).Each assembly that test instrumentation exists under the search system when starting, the registration function by calling each assembly with the assembly dynamic load in system.
(3) log-on message of assembly is wanted the function of this assembly of energy unique identification, so will comprise component Name in the log-on message, particularly, component Name can use as the SCPI of one of test instrumentation standard (Standard Command for Programmable Instruments, programmable instrument standard commands) and order; The log-on message of assembly also should comprise the position of realizing this assembly function, and function address normally is so also will comprise the function pointer that assembly function is realized in the log-on message; Other information also should comprise the parameter value relevant with concrete function, parameter type or the like, and these information are registered in command mapping table, parameter configuration table and three structures of metadata cache of micro-kernel.Deposit all SCPI orders in the command mapping table, parameter configuration table is deposited the parameter information that the SCPI order need be used, and metadata cache is deposited measurement result.
(4) as shown in Figure 3, master control need provide unified dispatch interface for each functional unit, with convenient each assembly of scheduling according to step (2) (3) (4).Mainly comprise three interfaces:
1. the command analysis interface of micro-kernel is responsible for the SCPI order that interpretive analysis user applying portion sends to micro-kernel, carries out the corresponding function of this order then.The command analysis interface is the core of micro-kernel, and the scheduling of each function, the inquiry of information all need to finish by this module.This interface mainly offers user's application module and uses.
Particularly, shown in inner each module of Fig. 3 micro-kernel, the work of command analysis interface is, when micro-kernel from user's application module receive SCPI order the time, micro-kernel at first makes an explanation to order, analyzes its legitimacy, in the command mapping table, search this order then, if order does not exist, return wrong status information, if there is the attribute of further judging order in order.If this order is to want the query argument setting, then search parameter configuration table, the parameter that inquires is directly fed back to user's applying portion by the command analysis interface; If this order will be inquired about measurement result, then search metadata cache, give user's applying portion with the measurement feedback that inquires; If this order will be carried out parameter modification, then revise parameter configuration table, calling function Executive Module then earlier; If this order need not revised parameter, then direct calling function Executive Module.
2. the parameter query interface of micro-kernel offers the current parameter configuration of each functional unit inquiry.When micro-kernel calls a certain function,, and then carry out concrete function at first by the current parameter configuration of parameter query interface inquiry.
By the function of command analysis interface as can be known, micro-kernel is at first revised parameter list calling function assembly then, and functional unit need pass through parameter query interface accessing parameter list, obtains the current parameter revised of needing, and is carrying out concrete modify feature then.
3. the data of micro-kernel report interface, are responsible for measurement result is stored in the metadata cache, and user's application module can go measurement result in the data query buffer memory by the command analysis interface then, show or pass to the Long-distance Control user.This interface mainly offers measures the assembly use.

(3) each of current instrument support measured in the initialization procedure of program start and successfully be registered in the system, when carrying out a concrete measurement, user's applying portion can initiate to measure sign on then, and this message is delivered to micro-kernel and handled.Micro-kernel is by the querying command mapping table, and the computing module of scheduling measurement assembly is measured calculating, and result of calculation is reported to data buffer area, and user's applying portion is shown on the interface as required or further reports Long-distance Control.
3, protocol stack control assembly design
(1) the protocol stack control assembly can be loaded in the system dynamically, for terminal provides testing protocol consistency.The protocol stack control assembly is divided into assemblies such as protocol stack parameter modification, calling control, and each assembly includes Registering modules and control module.Because the real-time of protocol stack is had relatively high expectations, there be (implementation method of protocol stack is not in this document discussion scope) in protocol stack with process independently, so protocol stack control is mainly finished by interprocess communication, the control module of protocol stack control assembly is finished concrete parameter modification or CCF by sending message to protocol stack and receiving feedback from protocol stack.
(2) registering functional uses the registration interface that micro-kernel provides, and protocol stack parameter modification and the information of calling out each function in the control are registered in the command mapping table and parameter configuration table of micro-kernel.
(3) the protocol stack control assembly also passes through to finish testing protocol consistency in the successfully adding system of registration interface in the initialization procedure of program start.Test platform to the concrete control flow of protocol stack is: at first, the user chooses required control on user's application module, comprise parameter modification, endpoint registration, calling etc., and user's application module sends corresponding message to micro-kernel; Then, micro-kernel is searched the log-on message of protocol stack in command mapping table and parameter configuration table, and then sends message to the protocol stack process; At last, micro-kernel receives the message feedback of protocol stack process, transmits and is reacted on user's application module.
4, system's control assembly is set
(1) system's control assembly can dynamic load in system, can be divided into assemblies such as radio frequency control, calibrating indicating instrument, meter information inquiry according to function.Assembly designs according to unified structure, comprises Registering modules and control module.
