Description

Measurement resource control system and measurement resource control method

technical field

The present invention relates to a measurement resource control system and a measurement resource control method, in particular to a measurement resource control system running on a computer and used to manage multiple measuring instruments and multiple application programs and the measurement resource control method adopted therefor .

Background technique

In the fields of industrial engineering and scientific education, measuring and testing instruments are indispensable basic tools in experiments, manufacturing, testing, etc., such as oscilloscopes, multimeters, spectrum analyzers, and signal sources are commonly used general-purpose measuring instruments. With the continuous development of science and technology, measuring instruments are also transformed from analog measuring instruments to digital measuring instruments. Digital measuring instruments have many advantages that analog measuring instruments do not have, such as convenient storage, convenient data analysis and calculation, strong anti-interference and so on. In addition, the digital measuring instrument also has a unique advantage that it can be easily connected with a computer to form a measuring system, using the rich resources and powerful functions of the computer to control the measuring instrument and update the measurement results. for complex processing.

Due to the above-mentioned advantages, measurement systems composed of computers and measuring instruments have been extensively researched and developed. It is worth mentioning that due to the powerful data processing and display functions of computers, measuring instruments such as oscilloscopes only play the role of data acquisition in the measurement system, and their own data processing and display functions become a waste. Therefore, the measurement board was born. The measurement board is also regarded as a kind of measuring instrument. Unlike an oscilloscope, it only has the function of data acquisition, and it does not process or display data itself. When in use, the measurement board generally needs to be plugged into the IO interface of the computer. For example, the measurement board can pass through the VXI (VME extensions for Instrumentation) bus, PXI (PCI extensions for Instrumentation) bus, GPIB (General Purpose Interface Bus), And the serial port (serial port) or parallel port (parallel port) of the computer to connect with the computer.

According to the above introduction, please refer to FIG. 1 , the current measuring system 1 includes a computer 11 and at least one measuring instrument 12 , and each measuring instrument 12 is connected to the computer 11 through an interface 13 . The computer 11 may be a personal computer (PC), a server (server), or a client (client) connected to the server, etc., which has data calculation and processing functions. The measuring instrument 12 is a device with a data acquisition function, which may be a measuring instrument such as an oscilloscope, a multimeter, a spectrum analyzer, a signal source, a measuring board, or even a sensor. The interface 13 can be VXI bus, PXI bus, GPIB, serial port, parallel port, or LAN port, and the serial port includes USB interface, RS232 and so on.

Due to the diversity of the interfaces 13 , the computer 11 generally installs an interface driver 111 , such as a VISA driver, for shielding differences caused by different interfaces 13 . Based on the interface driver 111 , the computer 11 can communicate various commands to the measuring instrument 12 through the standardized SCPI command set 112 to perform corresponding operations. The SCPI command set 112 includes a plurality of SCPI commands. Different SCPI commands are used to perform different operations on the measuring instrument 12. The operations include controlling the measuring instrument 12, configuring the parameters of the measuring instrument 12, and reading from the measuring instrument 12. data etc.

There are many SCPI commands. In order to facilitate users to control different measuring instruments 12 and perform various calculations on measurement results, the computer 11 also includes at least one application program 14 . The application program 14 can be based on the interface driver program 111 and the SCPI command set 112, using programming language tools such as VC, VB, LabVIEW, etc., developed by developers, users themselves, or others, and used to control the computer 11 to measure the measuring instrument 12. Various operations and processing of measurement data, etc. For example, please refer to FIG. 2 . FIG. 2 shows a display interface 1490 applied to an application program of a spectrum analyzer disclosed in the prior art. The display interface 1490 has a plurality of input windows 1491, and the user can conveniently input various operations on the measuring instrument 12 through the input windows 1491, instead of directly sending SCPI commands to the measuring instrument 12; the display interface 1490 also has a waveform display window 1492 , used to display the measurement data acquired by the computer 11 from the measuring instrument 12 in the form of graphs.

Due to the variety of measuring instruments 12 , the specifications, parameters or functions of each measuring instrument 12 are different. Different application programs 14 generally need to be developed for different measuring instruments 12 . Please refer to FIG. 3 , for example, a power supply 121 whose model is DP1308A corresponds to an application program 141 ; a spectrum analyzer 122 whose model is DSA1030A corresponds to an application program 142 . In addition, even the same type of measuring instrument 12 may have different specifications, parameters, or functions due to different models and versions, so sometimes it is necessary to develop different application programs 14 .

In addition, for some special applications, multiple same or different measuring instruments 12 need to work together to achieve a certain measuring task. Therefore, multiple measuring instruments 123 can correspond to an application program 143, and the application program 143 requires Only when the multiple measuring instruments 123 work simultaneously can the measuring task be completed.

In addition, multiple application programs 144 can also be developed for one measuring instrument 124 to be used to realize different functions respectively; In the case of multiple measuring instruments 125 , the application program 145 can work independently with each measuring instrument 125 . For example, the application program 145 is compatible with both the spectrum analyzer 125 of model DSA1030A and the spectrum analyzer 125' of DSA1000A.

Referring to FIG. 4 , the computer 11 includes a CPU 114 , a memory 115 , a hard disk 116 and a bus 117 . The CPU 114 , the memory 115 , and the hard disk 116 are respectively connected to the bus 117 and communicate through the bus 117 . Application 14 is an executable program that is typically stored on hard disk 116 when not being executed. When called to run, after the user inputs an instruction to open the application program 14 through the operating system of the computer 11 , the application program 14 is loaded into the memory 115 and can be executed by the CPU 114 .

Please refer to FIG. 1 and FIG. 5 together. When the application program 14 is executed, the computer 11 executes the following steps in sequence under the control of the application program 14:

Step S1, instrument search step;

Although according to the foregoing, the measuring instrument 12 has been connected to the computer 11 through an interface 13, this connection only connects the measuring instrument 12 to the interface 13, and does not configure the measuring instrument 12, such as interface configuration, to obtain the measuring instrument. 12, the computer 11 cannot establish communication with the measuring instrument 12 at this time. Therefore, the instrument search step mainly completes the configuration of the measuring instrument 12 to obtain an original address corresponding to the measuring instrument 12 . It should be noted that even if the original address is obtained, the connection is only on a physical level, that is to say, the computer 11 can use the original address to communicate with the measuring instrument 12 . According to the above, since there are various correspondences between the application program 14 and the measuring instrument 12, completing the instrument search step does not mean that the application program 14 can control the computer 11 to operate and control the measuring instrument 12 Therefore, it is necessary to further identify the basic information of the connected measuring instrument 12 to determine whether the connected measuring instrument 12 matches the application program 14, or which measuring instrument 12 among the connected multiple measuring instruments 12 is compatible with the application program. Program 14 matches.

Step S2, instrument connection step;

Step S2 mainly completes the logical connection between the measuring instrument 12 and the computer 11, and establishes a communication channel between the measuring instrument 12 and the computer 11 at the application level. That is, the identification of the instrument model needs to be completed to ensure that the instrument is the measuring instrument 12 corresponding to the application program 14 , that is, to determine whether the subsequent instrument application steps can control the measuring instrument 12 .

The specific work of step S2 is: receive the original address, use the original address to send a command to the measuring instrument 12, query the basic information of the instrument, analyze the basic information of the instrument returned by the measuring instrument 12, and analyze the basic information of the instrument according to the basic information of the instrument. Manufacturer name, instrument model, instrument serial number, instrument version number, etc., determine whether the measuring instrument 12 is the measuring instrument 12 corresponding to the application program 14 according to the analyzed manufacturer name, instrument model, instrument serial number, instrument version number, etc.

Step S3, instrument application steps;

The work of step S3 includes: 1. Utilize the original address to control the computer 11 to communicate with the measuring instrument 12. The communication content includes receiving the measurement data of the measuring instrument 12, sending SCPI commands to the measuring instrument 12 to control the measuring instrument 12, etc.; 1. Provide a display interface, please refer to FIG. 2, for example, it is the display interface of the application program of the spectrum analyzer, the received measurement data is displayed in the form of curves through the waveform display window 1492, and user input is received through the input window 1491 and other modes command and convert it into a corresponding SCPI command and send it to the measuring instrument 12.

Please refer to Fig. 6, application program 14 comprises an instrument search module 147 for controlling computer 11 to realize step S1, an instrument connection module 148 for controlling computer 11 to realize step S2 and an instrument for controlling computer 11 to realize step S3 Application module 149.

A software (Measurement & Automation Explorer, MAX) released by National Instruments (NI) that can be used to verify the communication between the computer and the measuring instrument can also obtain the original address of the measuring instrument through step S1, but the software only generates the original address. There are no subsequent steps S2 and S3.

Agilent (Agilent) has also released a software (Agilent Connection Expert) that can be used to verify the communication between the computer and the measuring instrument. This software can also generate the original address and obtain the basic information of the instrument through steps S1 and S2. Only the original address and the basic information of the instrument are generated, and there is no subsequent step S3.

According to the previous introduction, it can be seen that with the continuous increase of the types and models of the measuring instruments 12 and the continuous increase of various application requirements, the application programs 14 are constantly being developed in large quantities, and the number increases significantly. This causes the following problems: a slight change in the model of the measuring instrument 12 may cause the application program 14 to be redeveloped, and the instrument search module 147, the instrument connection module 148 and the instrument application module 149 still need to be redeveloped when the application program 14 is developed, so that The development and maintenance process of the application program 14 is complex and costly.

detailed description

The first implementation manner of the measurement resource control system of the present invention is introduced below.

Please refer to FIG. 7 , the measurement resource control system 4 is applied in a measurement system 2 . The measurement system 2 includes a plurality of measurement resources 20 and a measurement resource control system 4 for managing and controlling the plurality of measurement resources 20 . The plurality of measurement resources 20 includes a plurality of measurement instruments 22 and a plurality of application resources. In this embodiment, the application resources are application programs 24 .

The measuring instrument 22 is a device with a data acquisition function, and may be a measuring instrument, such as an oscilloscope, a multimeter, a spectrum analyzer, a signal source, a measuring board, or even a sensor. The measurement resource control system 4 is realized by a computer and measurement resource control system software running on the computer. The computer may be a personal computer, a tablet computer, a server or a client connected to the server, and other devices with data calculation and processing functions. The measuring instrument 22 is connected to the measurement resource control system 4 through an interface, and the interface may be a VXI bus, a PXI bus, GPIB, a serial port, a parallel port, or a LAN port.

Please refer to FIG. 8 , in this embodiment, the computer 41 used by the measurement resource control system 4 includes a CPU 414 , a memory 415 , a storage 416 , a bus 417 , a display screen 418 and peripherals 419 . CPU414, memory 415, memory 416 are connected with bus 417 respectively, display screen 418 is connected with bus 417 through graphics card 419, peripheral hardware 419 is connected with bus 417 through various interfaces, CPU414, memory 415, memory 416, display screen 418 and external Set 419 to communicate via bus 417 . The memory 416 is composed of a hard disk, and of course it can also be a flash memory, an optical disk, a magnetic disk, and the like. Peripherals 419 include mouse, keyboard and so on.

Due to the variety of measuring instruments 22 , the specifications, parameters or functions of each measuring instrument 22 are different. Generally, different application programs 24 need to be developed for different measuring instruments 22 , that is, each measuring instrument 22 has its corresponding application program 24 . Please refer to FIG. 9 , for example, a power supply 221 whose model is DP1308A corresponds to an application program 241 ; a spectrum analyzer 222 whose model is DSA1030A corresponds to an application program 242 . In addition, even the same type of measuring instrument 22 may have different specifications, parameters, or functions due to different models and versions, so sometimes it is necessary to develop different application programs 24 .

In addition, for some special applications, multiple same or different measuring instruments 22 need to work together to achieve a certain measuring task. Therefore, multiple measuring instruments 223 can correspond to an application program 243, and the application program 243 requires Only when the multiple measuring instruments 223 work simultaneously can the measuring task be completed.

In addition, multiple application programs 244 can also be developed for one measuring instrument 224 to realize different functions respectively; for some measuring instruments 225, such as the same type but different types of measuring instruments, there can also be one application program 245 that can be compatible In the case of multiple measuring instruments 225, the application program 245 can work with each measuring instrument 225 independently. For example, the application program 245 is compatible with both the spectrum analyzer 225 of model DSA1030A and the spectrum analyzer 225' of DSA1000A.

The application program 24 is an executable program that is stored in the memory 416 of the computer 41 when not being executed. Referring to FIG. 10 , the application program 24 includes an instrument application module 249 . Since the application program 24 no longer includes an instrument search module and an instrument connection module, the computer 41 cannot be controlled to obtain the original address of the measuring instrument 22 only by executing the application program 24, but it is necessary to wait for the measurement resource control system 4 to deliver the original address to the application program 24, that is, the computer 41 cannot be controlled to establish communication with the measuring instrument 22 only by running the application program 24 . Therefore, the user cannot control the measuring instrument 22 by directly running the application program 24 .

The following describes how the measurement resource control system 4 manages and controls the measurement resources 20 .

Referring to FIG. 11, the measurement resource control system 4 performs the following steps:

Step S11, instrument resource management step: establish a connection with the measuring instrument, and generate an original address and an instrument identifier corresponding to the measuring instrument. Wherein, step S11 includes step S111 and step S112:

Step S111, instrument search step: generating the original address of the measuring instrument;

The work of step S111 includes completing the original search of instrument resources, that is, finding the measuring instrument 22 connected to the computer 41 and in the power-on state (also called online state), and obtaining an original address. Since the measuring instrument 22 can be connected to the computer 41 through different interfaces, the search method and the original address acquisition method are also different for different interfaces.

According to the use form of the interface, the search methods are divided into three categories: the first type: automatic search, the plug-and-play method triggers the search step, such as the USB-TMC interface; the second type: semi-automatic search, which needs to manually trigger the search step or configure the trigger Conditions to trigger the search step, such as LAN-VX-11 interface; the third type: manual search, the search is realized by inputting configuration data to connect the instrument, such as RS232 interface.

For automatic search, take the USB-TMC interface as an example, which is based on the Universal Serial Bus Test and Measurement Class Specification (USBTMC) and Universal Serial Bus Test and Measurement Class, Subclass USB488 Specification (USBTMC-USB488). After the measuring instrument 22 is connected to the computer 41, the operating system (such as Windows) will install the driver for it (Windows Vista and 7 will be automatically installed, and other versions need to be manually installed). After the driver installation is completed, the measurement resource control system 4 will be triggered by the action of connecting the measuring instrument 22 to the computer 41, and the measurement resource control system 4 will call the USB-TMC lookup function of VISA to obtain the address information of the USB-TMC interface, which is the original address.

For the semi-automatic search, take the LAN interface as an example to illustrate, it is based on the VX-11 protocol and the mDNS protocol to complete the search of the LAN interface instrument. Since there are two sets of protocols coexisting on the upper layer of the existing LAN interface (VX-11 and mDNS), there are two sets of search methods for it.

For the VX-11 interface instrument, the search method is to send a search message to the LAN, and accept the response of the message within a certain period of time. The IP of the response is regarded as the measuring instrument to be determined, and the IP of the response constitutes the original address. Referring to FIG. 12 , there is a “LAN” button 140 on the display interface of the measurement resource control system 4 , and the user triggers step S11 by clicking the “LAN” button 140 .

For devices with mDNS interface (meeting this protocol and VX-11 protocol), the mDNS interface instrument also supports the mDNS-based search method on the basis of the above-mentioned search method, that is, when the device that meets the mDNS protocol is connected to the network, the resource is measured The control system 4 will receive the connection request report of the device, and the measurement resource control system 4 obtains the resource information through the report, and the resource information constitutes the original address. The measurement resource control system 4 also includes a timing resource online status verification function. If an mDNS device is disconnected, the measurement resource control system 4 will automatically clear the measurement instrument 22 .

For the manual search, the GPIB interface is used as an example to illustrate that the search is completed based on the IEEE488.1 and IEEE488.2 protocols. Please refer to FIG. 13 , the user connects the instrument by inputting GPIB parameters in the window 150 , and the inputted parameters constitute the original address 151 .

For the manual search, the RS232 interface is used as an example to illustrate that the search is completed based on the EIA 232 standard. Referring to FIG. 14, the user connects the instrument by inputting RS232 parameters in window 160, and the input parameters constitute the original address.

Step S112, the instrument connection step: sending a command to the measuring instrument according to the original address, obtaining the basic instrument information of the measuring instrument, and generating the instrument identification according to the basic instrument information.

The measurement resource control system 4 connects the instrument according to the original address, and communicates with the instrument. The content of the communication is to send an SCPI command to the measuring instrument 22, that is, the "*IDN?" command. This command is a basic command in the SCPI standard. If you send an "*IDN?" is recorded. The basic information of the instrument will be obtained in the returned data of the "*IDN?" version number, etc., and use at least a part of the basic information of the instrument as the instrument identification of the measuring instrument 22.

For example: the original address generated in step S11 is: USB0::0x0400::0x09C4::DSA1A113600019::INSTR, and step S12 sends: "*IDN?" , get the basic information of the responding instrument: "XXXX, DSA1030A, DSA1A113600019, 00.01.03.01.01". By analyzing the basic information of the instrument, "manufacturer information: "XXXX", "model information: DSA1030A" and so on are obtained.

Please refer to FIG. 15 , in this embodiment, the measurement resource control system 4 uses the model information as the instrument identifier 220 of the measuring instrument 22 . For example, the original address in the above example is: USB0::0x0400::0x09C4::DSA1A113600019::INSTR and the instrument ID of the measuring instrument 22 is “DSA1030A”. For another example, the instrument identifier 220 of another measuring instrument is "DS1204B". In other implementation manners, the instrument identification may also include the manufacturer's name, instrument serial number, instrument version number, etc. in the basic information of the instrument, or may also include the original address.

Step S12, input step: select a selected measuring instrument from the measuring instruments through the instrument identification, and select a selected application resource from the application resources; wherein, step S12 includes steps S121-S124:

Step S121, an instrument list generating step: according to the instrument identification, generate an online instrument list corresponding to the instrument identification;
