Abstract
The utility model discloses a digital multimeter based on the wifi wireless transmission, comprising a digital multimeter body; a measuring circuit in the digital multimeter body is connected with a central processor, a wifi module connected with the central processor is further arranged in the digital multimeter body, the wifi module is in network connection with a computer equipped with a communication software through a wireless router externally placed outside the digital multimeter body to perform the wireless communication. Compared with the prior art, the digital multimeter does not need to be wired, and is flexible and simple in structure, convenience in expansion, far in transmission distance, free from limitation of node number, high in reliability and relatively low in maintenance cost at later period.
Description
Technical field
The utility model relates to a kind of digital multimeter, particularly a kind of digital multimeter based on the wifi wireless transmission.
Background technology
Digital multimeter 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; Pass through communication interface; Computing machine can write down reading when digital multimeter is measured; Perhaps from digital multimeter equipment a group number-reading data upload to computing machine, but the shortcoming of these transmission modes is bus efficiencies real-time low, system reliability poor, communication is low, the cost of later maintenance 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 existing problem of above-mentioned existing digital multimeter communication interface, the utility model aims to provide a kind of digital multimeter based on the wifi wireless transmission.
The utility model is to address the above problem the technical scheme that is adopted to be: a kind of digital multimeter based on the wifi wireless transmission; Contain the digital multimeter body; The intrinsic metering circuit of digital multimeter is connected with central processing unit; It is characterized in that: in the digital multimeter body, also be provided with the wifi module that is connected with central processing unit, the wifi module is set up network and is connected and carries out radio communication through being placed on this external wireless router of digital multimeter and computer.
Data transmission in the utility model between intrinsic wifi module of multimeter and the computer adopts ICP/IP protocol; The employed computer of the utility model is equipped with bitcom; Can not only receive the measurement data of multimeter; Can also be to the measurement gear of multimeter, parameters such as range are carried out long-range setting.
Adopt technique scheme, be connected with central processing unit, carry out radio communication after setting up network and be connected through wireless router and the computer that bitcom is installed then through the wifi module is installed in the digital multimeter body; The data that central processing unit collects the front end metering circuit constantly send to the wifi module after wireless router is transferred on the computer, by the bitcom on the computer data decode that receives are analyzed to show.
Compared to prior art, the utility model does not need wiring, and flexibly simple, expansion convenience, long transmission distance, no node number limit, reliability height and later maintenance cost are lower.
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.wifi module; 30. wireless router; 40. computer.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As
Fig. 1Shown a kind of digital multimeter based on the wifi wireless transmission 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 wifi 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, wifi module 20 is set up wireless connections with computer 40 through wireless router 30, the data transmission employing ICP/IP protocol between wifi module 20 and the computer 40 that bitcom is installed.Direct integrated wifi modules of using with communication 20 in the digital multimeter body 10 are carried out wireless 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 wifi module 20 to after central processing unit 12 is handled, and is wirelessly transmitted on the computer 40 through wireless router 30, by the bitcom on the computer 40 data decode that receives is analyzed to show.
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, also can 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.
