Abstract
A digital multimeter based on a Bluetooth interface comprises a digital multimeter main body; a measurement circuit in the digital multimeter main body is connected with a central processing unit; a Bluetooth module connected with the central processing unit is arranged in the digital multimeter main body, and is matched with and in wireless data connection with a Bluetooth module built-in an intelligent mobile phone, and data communication is carried out through corresponding client software of the intelligent mobile phone; and the data acquired by the measurement circuit at the front end is sent to the Bluetooth module by the central processing unit constantly and then is wirelessly transmitted to the intelligent mobile phone for the communication software on the mobile phone to decode, analyze, and display the received data. The digital multimeter adopts wireless communication, is not limited by a transmission line, has long stable transmission distance and high data security, supports main-stream intelligent mobile phone operating systems, and is qualified for data measurement under various harsh environments.
Description
Technical field
The utility model relates to digital multimeter, particularly a kind of digital multimeter based on blue tooth interface.
Background technology
The communication modes of existing digital multimeter is to link to each other with personal computer mostly, is main with infrared ray, RS-232, RS-485 or USB interface etc. mainly, and through these modes, computing machine can show when measuring and the record reading in real time.But,, carry inconvenience because the personal computer volume is bigger; Some scopes of activities are narrow be difficult near or proemial measurement target; Then be difficult to control if will use above-mentioned traditional communication modes to carry out the remote measurement monitoring, nowadays smart mobile phone is very universal, and Bluetooth technology is quite ripe; If wireless remote shows the measurement data of the multimeter good method of can yet be regarded as on mobile phone, but existing multimeter does not all have embedded with bluetooth interface or matched handset bitcom.
The utility model content
For solving existing digital multimeter defective, the utility model aims to provide a kind of digital multimeter based on blue tooth interface; Blue tooth interface module and mobile phone peripheral hardware through being embedded in multi-platform mobile communication software carry out wireless telecommunications, realize the digital multimeter remote monitoring, promptly implement to measure and digital display reading real time record.
For reaching above-mentioned purpose; The utility model provides a kind of digital multimeter based on blue tooth 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 bluetooth module that is connected with central processing unit, the bluetooth module pairing that this module and smart mobile phone are built-in is also set up wireless data and is connected.
The client software that the smart mobile phone of the utility model is installed is supported ios, android and windows phone operating system platform; Bluetooth module and the built-in bluetooth module of smart mobile phone that central processing unit connects carry out data communication through correspondent customer terminal software; The smart mobile phone client software of the utility model can not only show and write down the screen message of multimeter in real time; Can also be to the gear of multimeter, parameters such as range are carried out long-range setting.
Adopt technique scheme, be connected with central processing unit through bluetooth module is installed in the digital multimeter body, then through the wireless pairing connection of intelligent of bluetooth module mobile phone; The data that central processing unit collects the front end metering circuit are wirelessly transmitted on the smart mobile phone after constantly sending to bluetooth module, by the bitcom on the mobile phone data decode that receives are analyzed to show.
Compared to prior art, the utility model adopts radio communication, do not receive transmission line to impede, transmit that stabilizing distance is far away, data security is high, supports the main flow operation system of smart phone, can be competent at the DATA REASONING work under the various severe rugged environments.
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. bluetooth module; 30. smart mobile phone.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As
Fig. 1Shown is a kind of based on the digital multimeter with blue tooth interface, includes digital multimeter body 10 and the smart mobile phone 30 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 bluetooth module 20 that is connected with central processing unit 12; The signal of the collection of metering circuit 11 sends to and exports bluetooth module 20 to after central processing unit 12 is handled, through setting up wireless connections with smart mobile phone 30 built-in bluetooth module pairings; The utility model smart mobile phone 30 client softwares are supported mainstream operation system ios, android and windows phone; Through the time of the real-time gear that shows and write down digital multimeter body 10 in back that the data that receive are decoded, the value of reading, record; And can be to the measurement gear of digital multimeter body 10, parameters such as range are carried out long-range setting.
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.
