The system consists of a PC (Personal Computer) machine and data acquisition equipment, wherein the PC machine is provided with an application program of the virtual digital oscilloscope. The system is characterized in that the data acquisition equipment comprises an A/D (Analog/Digital) conversion module and an Ethernet transmission module, a data signal is converted into a digital signal through the data acquisition equipment, and the digital signal is transmitted to the PC machine through the Ethernet transmission module. In the utility model, with the adoption of the acquisition equipment by taking an embedded processor as the core, the system is provided with an open and transparent interface, and users can rewrite the program of the virtual digital oscilloscope according to the experimental requirement, so that the hardware cost is reduced; in addition, with the addition of an network interface, the oscilloscope can exchange information and orders in the local area network or the wide area network, so as to expand the application range of the virtual digital oscilloscope, be more beneficial for establishing a distributed network measuring system and realize the remote sharing of the data and devices, thereby serving the remote observation and control experiment.
Description
Technical field
The utility model relates to a kind of virtual Digital Oscilloscope system that has network transmission function, belongs to the virtual instrument field.
Background technology
In actual applications, when the equipment of electronics, measurement class used, experimental occasions needed unmanned or operated from a distance, measurement and monitoring; In some open laboratory, digital oscilloscope involves great expense, limited amount, and the user may damage instrument if do not understand method of operating.Therefore virtual Digital Oscilloscope has been arranged, the problems referred to above are solved.The most data collecting cards that use particular vendors to provide of present existing virtual Digital Oscilloscope.It comprises A/D modular converter and various communication interface modules in inside, because communication protocol is opaque, make the virtual oscilloscope application program be subjected to the restriction of capture card hardware, and the ratio of performance to price is unsatisfactory, is difficult in common lab and promotes.In addition, present most virtual instrument all is to adopt RS232 or USB as interface, along with development of internet technology, and the actual needs of remote collection and transmission, call virtual unit with networked transfer function.
Summary of the invention
In order to overcome the problems referred to above of existing virtual oscilloscope, the utility model provides a kind of network transmission function virtual Digital Oscilloscope that has, and utilizes flush bonding processor as collecting device, and realizes the remote capture and oscillographic the sharing of signal.
To achieve these goals, the utility model adopts following technical scheme:
Design a kind of network virtual digital oscilloscope, constitute by PC with virtual Digital Oscilloscope application program and data acquisition equipment, described data acquisition equipment comprises A/D modular converter and Ethernet transport module, data-signal is converted to digital signal through data acquisition equipment, and digital signal reaches PC by the Ethernet transport module.
Described data acquisition equipment adopts flush bonding processor STM32F107 and 10/100Mb ethernet transceiver DP83848 to constitute, and the integrated two ADC of STM32F107 are as described A/D modular converter; The 10/100MAC that STM32F107 is built-in cooperates described 10/100Mb ethernet transceiver DP83848 as described Ethernet transport module.
The utlity model has following advantage: at first, it is the collecting device of core that flush bonding processor is adopted in design, has open, transparent interface, the user can experimentally need rewrite the virtual oscilloscope program, both saved hardware cost, and made the user more deep understanding be arranged oscillographic principle of work.Secondly, this virtual Digital Oscilloscope has been added network interface, make oscillograph can on LAN (Local Area Network) or wide area network, carry out information and order exchange, the usable range of virtual oscilloscope has been expanded in this network service, more help to set up distributed network measure system, realize the long-range shared of data and instrument, thereby be remote measurement and control experiment service.

Embodiment
Describe a kind of embodiment of the present utility model in detail below in conjunction with accompanying drawing.
The system architecture diagram of network virtual digital oscilloscope is by shown in Figure 1 in the present embodiment.The PC that mainly comprises data acquisition equipment and the virtual oscilloscope application program has been installed.Data acquisition equipment adopts flush bonding processor STM32F107, it is the interconnected type series microprocessor of the STM32 that releases recently of STMicw Electronics, dominant frequency is 72MHz, has abundant peripheral hardware such as ram in slice, built-in 10/100MAC module, 12 A/D converters of 16 passages.Utilize its integrated two ADC realization signal double channel A/D collection.Simultaneously, it is built-in with 10/100MAC, adds 10/100Mb ethernet transceiver DP83848 in the processor outside, has realized the network interface of data acquisition equipment.
The virtual oscilloscope application program adopts the LabVIEW graphical programming language, utilize modular software design idea to write, the realization of each function is finished by a module, system software comprises five big basic modules such as data acquisition, waveform demonstration, parameter measurement, spectrum analysis, data storage and playback generally, also can be according to different experiments, add corresponding function, for example, can add filter function etc.This design makes that the function expansion of virtual oscilloscope is very simple and convenient.
Concrete network transmission process is by shown in Figure 2: data acquisition equipment is as server end, and the virtual oscilloscope application system of PC end is as client.Whether server is monitored at designated port has client-requested to connect, when the user end to server end sends connection request, after success connects, enter major cycle and send control word to embedded system parsing, execution data acquisition, then data are transferred to client again, close connection at last, finish data acquisition one time.
