Abstract
Provided is a digital universal meter based on an Ethernet interface, comprising a digital universal meter body, with a measuring circuit inside the digital universal meter body being connected with a central processor. The portable digital universal meter is characterized in that: an Ethernet module is arranged inside the digital universal meter body for connecting with the central processor; the Ethernet module is connected with a computer installed with communication software or with the computer network via an RJ45 netting twine; the digital universal meter is internally provided with the Ethernet module for connecting with the central processor, with the RJ45 netting twine being used for connecting the Ethernet module with a computer or with a computer network; the central processor continuously sends the data collected by a front measuring circuit to the Ethernet module and then the data is transmitted upon the computer via the RJ45 netting twine; and the communication software installed upon the computer is in charge of decoding, analyzing and displaying the received data. Compared with the prior art, the utility model features flexible and simple wiring, convenient expansion, no limit on node, long transmission distance, high reliability, and low later maintenance cost.
Description
Technical field
The utility model relates to a kind of digital multimeter, particularly a kind of portable digital multimeter based on Ethernet interface.
Background technology
Digital multimeter is popularized, and has the irreplaceable advantage of many simulated pointer formula multimeters.The modern digital multimeter can link to each other with personal computer; Be main mainly with infrared ray, RS-232, RS-485 or USB interface; Through these modes; Computing machine can write down reading when measuring; Perhaps slave unit uploads to one group of result in the computing machine, but these transmission mode shortcomings are that bus efficiency is low, the real-time of system is poor, reliability communication is low, later maintenance cost is high, the network engineering debugging is complicated, transmission range node undesirable, that unibus can articulate is few, it is dumb etc. to use, and can't meet the demands than higher monitoring field at ask for something.
The utility model content
For solving the defective of existing digital multimeter communication interface, the utility model aims to provide a kind of portable digital multimeter based on Ethernet interface.
The technical scheme that the utility model addresses the above problem employing is: a kind of portable digital multimeter based on Ethernet interface; Contain the digital multimeter body; The intrinsic metering circuit of multimeter is connected with central processing unit; It is characterized in that: in the digital multimeter body, be provided with the ethernet module that is connected with central processing unit, ethernet module is connected with computer or computer network through the RJ45 netting twine.
Adopt technique scheme, be connected with central processing unit, connect ethernet module and computer or computer network through the RJ45 netting twine then through ethernet module is installed in the digital multimeter body; The data that central processing unit collects the front end metering circuit constantly send to ethernet module after the RJ45 netting twine is transferred on the computer, by the bitcom on the computer data decode that receives are analyzed to show.
Compared to prior art, it is lower that the utility model wiring is simple flexibly, expansion is convenient, no node is counted restriction, long transmission distance, reliability height and later maintenance cost.
Description of drawings
Fig. 1 is the syndeton synoptic diagram of the utility model.
Accompanying drawing is designated among the figure: 10. digital multimeter body; 11. metering circuit; 12 central processing units; 20. ethernet module; 30.RJ45 netting twine; 40. computer.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As
Fig. 1Shown a kind of portable digital multimeter based on Ethernet interface includes digital multimeter body 10 and the computer 40 that bitcom is installed; Metering circuit 11 in the digital multimeter body 10 is connected with central processing unit 12; In digital multimeter body 10, also be provided with the ethernet module 20 that is connected with central processing unit 12; Computer 40 is equipped with the bitcom that adopts ICP/IP protocol; Bitcom can be on computer 40 monitoring display in real time and write down the job information of digital multimeter body 10; And can carry out long-range setting to the parameter of digital multimeter body 10, and ethernet module 20 is connected through RJ45 netting twine 30 with computer 40, and ethernet module 20 and the data transmission that is equipped with between the computer 40 of bitcom adopt ICP/IP protocol.Direct integrated ethernet modules of using with communication 20 in the digital multimeter body 10 carry out data communication with the central processing unit 12 of inside, can independently name change IP address and port numbers to digital multimeter body 10; The gear that can show and write down multimeter on the computer of bitcom in real time is installed; The value of reading, the time of record, and can be to the measurement gear of digital multimeter 10 bodies through computation; Parameters such as range are carried out long-range setting; The signal of the collection of metering circuit 11 sends to and exports ethernet module 20 to after central processing unit 12 is handled, and is transferred on the computer 40 through RJ45 netting twine 30, by the bitcom on the computer 40 data decode that receives is analyzed to show.
If need on a computer, monitor simultaneously to digital multimeter body 10; Also can RJ45 netting twine 30 be connected to equipment such as hub or router and set up into LAN; Each digital multimeter body 10 configuration independent IP address and port numbers utilizes the bitcom on the computer 40 that it is monitored simultaneously.
The foregoing description only supplies to explain the usefulness of the utility model; Those skilled in the art; Under the situation of spirit that does not break away from the utility model and scope, can also make various conversion or variation, therefore; All technical schemes that are equal to also should belong to the category of the utility model, are limited each claim.
