As shown in Figure 2, the specific implementation step is as follows:
A. at the unit type of certain type, create a model device Driver Library (the DLL form, as:
LNS513CanZongXianBK.dll, LNSAgilent34980A.dll, LNSSidaTemperature.dll), that all model device Driver Libraries have is unified, fixing interface definition:
1) device initialize interface: int LNSServiceInit (const char
*PRumXML).
Function declaration: according to the running configuration file of input parameter pRumXML sensing, the parsing operation configuration file, obtain the operational factor configuration information, characteristics according to model device, foundation is with the physical link (as: TCP/IP type, GPIB type, LXI type, USB type, RS232/485 type) of devices communicating, numerical value with the parameter configuration item, communication format protocol requirement with reference to equipment, send to entity device by communication link, finish device initialize work, equipment is in the ready duty of response instruction.
Input parameter: equipment operational factor configuration, as CAN1_RUN.XML, CAN2_RUN.XML comprises the parameter configuration item of equipment essential information.
The CAN1_RUN.XML content:
The CAN2_RUN.XML content:
Rreturn value: digital 0=success, non-0 represents the initialization failure, and each non-0 numeral identifies a kind of initialization failure cause, convenient location mistake.
2) equipment withdraws from interface: int LNSInstanceQuit (const char
*PEquipCode)
Function declaration: the equipment monitor of input parameter pEquipCode sign withdraws from the control running example, disconnects the physical link with entity device, and the resource that the releasing arrangement example takies is as internal memory, thread, semaphore, SOCKET handle etc.
Input parameter: pEquipCode, the equipment code name, sign belongs to the device instance of equipment code name.Rreturn value: digital 0=success, non-0 representative equipment withdraws from failure, and each non-0 numeral identifies a kind of equipment and withdraws from reason, convenient location mistake.
3) signalling arrangement withdraws from interface: int LNSServiceQuit ()

Rreturn value: digital 0=success, non-0 representative equipment withdraws from failure, and each non-0 numeral identifies a kind of equipment and withdraws from reason, convenient location mistake.
B. according to monitor, the demand of control, select the equipment that needs, configuration device to start.For example: certain test needs 2 CAN bus integrated circuit boards, an Agilent34980A collecting device, a SidaTemperature incubator equipment.One＜servers〉equipment of node identification, start configuration item file config.xml, form is as follows:
C. the equipment operation management module is opened startup configuration item file config.xml, one＜servers〉equipment of node identification.Scanning＜servers〉node, according to node＜EQUIP_TYPE 〉, load corresponding device drives storehouse (DLL form), node＜ServerConfig〉as input parameter, invocation facility Driver Library unified interface LNSServiceInit, finish device initialize work, make equipment be in program control commanded response ready state.Scan round＜servers〉node, finish the initial work of other equipment successively.
(4) device directive scheduler module
The device directive scheduler module, receive the program control instruction of equipment of all user's inputs, and the program control instruction of equipment of reception and the instruction in the program control instruction list of equipment are mated, if the match is successful, then plan the execution sequencing of the program control instruction of equipment, and trigger equipment instruction execution module; Otherwise, send instruction it fails to match information to the user;
Be example with certain model C AN bus integrated circuit board, the implementation procedure of declarative instruction scheduler module.
1) the program control instruction of this equipment has three kinds of authorities: the highest control authority, and control authority monitors authority, execution priority is: the highest control authority〉control authority〉the supervision authority;
2) the highest control authority can only license to a user, and control authority and supervision authority can license to a plurality of users;
3) instruction of same level authority, time priority, what arrive first carries out earlier;
4) have not interruptibility of atom during this equipment execution command, that is: the instruction of carrying out can not be interrupted, must be complete after, could select the highest instruction of next bar priority of execution;
5) instruction scheduling inside modules apparatus for establishing instruction priority query during the program control instruction of user input device, needs identifying user authority and coded instructions.For example: in certain test, this equipment has four user U0, U1, and U2, U3, U0 has the highest control authority, the U1 limit that is possessed of control power, U2 and U3 have the supervision authority.Suppose U0, U1, U3, U2 initiates calling coded instructions SendDataPackage (transmission packet) simultaneously, then putting in order of device directive priority is SendDataPackage(U0), SendDataPackage(U1), SendDataPackage(U3), SendDataPackage(U2); Carrying out SendDataPackage(U0) in the process, user U1 initiates coded instructions SetFrameSpace(is arranged frame period) call, then putting in order of device directive priority becomes SendDataPackage (U1), SetFrameSpace (U1), SendDataPackage(U3), SendDataPackage(U2); Execute SendDataPackage(U0) after, select to carry out SendDataPackage (U1), be SetFrameSpace (U1) then, next be SendDataPackage(U3), be SendDataPackage(U2 at last).
6) for the program control instruction calls of each Client-initiated equipment, at first can check coded instructions, the instruction in the matching instruction tabulation formation just can be adjusted device directive priority query and be put in order according to User Priority.Unmatched calling sends instruction it fails to match information to the user immediately, finishes the program control instruction calls flow process of primary equipment.
(5) device directive execution module
The device directive execution module, the corresponding input parameter value of the program control instruction of the equipment of all user's inputs is carried out verification, if verification is passed through, then according to the desired instruction input parameter of the control protocol of equipment form itself, the corresponding input parameter of the program control instruction of equipment is encoded and send to relevant device; Waiting facilities link order execution result, and execution result is sent to device parameter decoding management module; If verification is not by then sending error message to the user.
As shown in Figure 3, the specific implementation step is as follows:
1) the corresponding input parameter value of the program control instruction of extraction equipment checks the effective range of each input parameter value respectively
2) according to the control protocol institute requirement of equipment itself, with the input parameter value, convert correct formatted data to according to protocol requirement;
3) with formatted data, by the devices communicating link, send to entity device;
4) wait for entity device execution, link order execution result;
5) execution result is sent to device parameter decoding management module, finishes the execution of once command.
Be example with certain model C AN bus integrated circuit board, from the design of its facility information describing module about program control instruction list, the corresponding input parameter of the program control instruction of equipment, single parameter can abstractly be (parameter code name/parameter value/parameter type), for example instruct SetTCDataPackage (the temperature control data block is set), four parameters that relate to use the form of (circuit/1/ integer) (close/85/ integer) (model/1/ integer) (open/25/ integer) represent.And the data layout requirement of this model C AN bus board card control agreement is as follows:
CAN bus integrated circuit board for program control this model of energy need convert the form of four parameters (circuit/1/ integer) (close/85/ integer) (model/1/ integer) (open/25/ integer) to 080100000501550119AA.
Another model C AN bus integrated circuit board, the data layout of its control protocol require: K1=xxx; K2=xxx; K3=xxx; K4=xxx; Kx=xxx, the CAN bus integrated circuit board for program control this model of energy need convert the form of four parameters (circuit/1/ integer) (close/85/ integer) (model/1/ integer) (open/25/ integer) to circuit=1; Close=85; Model=1; Open=25.
In the same way, we describe (parameter code name/parameter value/parameter type) to this Unified Form that is designed to, and according to the different switching requirement, convert the process of concrete format protocol to, are called the instruction coding.Only need the unified IO interface of definition, code conversion method is encapsulated, with the form organization and management of dynamic base (DLL), the coding dynamic base that then can form seriation also claims to instruct code database.
Coding dynamic base IO interface definition: int COMMAND_CONVERT (const char
*PFormatInput, char
*PConvertResult);
Function declaration: the input data with the Unified Form description convert concrete format protocol to.
Input parameter: pFormatInput, the formatted data of satisfied (parameter code name/parameter value/parameter type)
Output parameter: pConvertResult meets the director data of concrete format protocol
Rreturn value: digital 0=success, non-0 represents convert failed, and each non-0 numeral identifies a kind of convert failed reason, convenient location mistake.
(6) device parameter decoding management module
Device parameter decoding management module to the execution result that the receives processing of decoding, is back to the user with equipment execution command situation.
Entity device receives program control instruction, carry out action, the processing of program control instruction agreement, with the output protocol form of execution result with equipment, turn back to the instruction execution module, execution result comprises two parts information, and whether a part characterizes program control instruction and run succeeded, after another part belongs to program control instruction execution, the data result that produces, the data result that the user needs.At the program control instruction that does not have data result, the instruction execution module only needs the form with rreturn value, and the sign implementation status gets final product, and does not need invocation facility parameter decoding administration module.Program control instruction SetBaud (baud rate is set) as certain model C AN bus integrated circuit board does not just have data result.At the program control instruction that data result is arranged, need be back to the user with a kind of unified format.
Be example with certain model C AN bus integrated circuit board, from the design of its facility information describing module about parameter list, its parameter value can adopt Unified Form to describe (parameter code name/parameter value/parameter type).And the data layout requirement of this model C AN bus board card control agreement is as follows:
Then its 21 parameters output as a result form be: 0801000016C8C8C8C8C8C8C8C864646464646464641B1B1B1B1BFC, its user can not directly use (collection be former code data, need carry out quantification treatment, multiply by scale-up factor, obtain the parameter result).
Another model C AN bus integrated circuit board, its parameter output protocol form is: V1; V2; V3; V4; Vx, its 21 parameter outputs form as a result are 20.0; 20.0; 20.0; 20.0; 20.0; 20.0; 20.0; 20.0; 10.0; 10.0; 10.0; 10.0; 10.0; 10.0; 10.0; 10.0; 27.0; 27.0; 27.0; 27.0; 27.0, though be direct result, use inconvenient.
In the same way, we become this output consequence devised Unified Form to describe (parameter code name/parameter value/parameter type), at various concrete format agreements, according to the different disposal requirement, are processed into the process that Unified Form is described, and are called the device parameter decoding.Only need the unified IO interface of definition, the parametric solution code method is encapsulated, with the form organization and management of dynamic base (DLL), then can form the parameter decoding dynamic base of seriation.
Parameter decoding dynamic base IO interface definition: int PARAM_DEAL (const char
*PInput, char
*PFormatResult);
Function declaration: the input data with the Unified Form description convert concrete format protocol to.
Input parameter: pInput, various concrete format agreements
Output parameter: pFormatResult, the formatted data of satisfied (parameter code name/parameter value/parameter type)
Rreturn value: digital 0=success, non-0 representation parameter decoding failure, each non-0 numeral identifies a kind of parameter decoding failure cause, convenient location mistake.
Handle through decoding, then two kinds of different protocol formats can be unified output, are user-friendly to.Unified output result: TA7/20.0/ floating type; The TA8/20.0/ floating type; The TA9/20.0/ floating type; The TA10.0/20.0/ floating type; The TA11/20.0/ floating type; The TA12/20.0/ floating type; The TA13/20.0/ floating type; The TA14/20.0/ floating type; The TA15/20.0/ floating type; The TA16/20.0/ integer; The TY3/10.0/ floating type; The TR6/10.0/ floating type; The TR7/10.0/ floating type; The TR13/10.0/ floating type; The TR14/10.0/ floating type; The TR15/10.0/ floating type; The TR16/10.0/ floating type; The TR36/27.0/ floating type; The TR37/27.0/ floating type; The TR38/27.0/ floating type; The TR39/27.0/ floating type.
