Description
Technical field
The present invention relates to a kind of industrial flow meter adjustment system, be specifically related to a kind of industrial flow meter adjustment system utilizing mobile phone to carry out wireless adjustment.
Background technology
Along with the development of economic technology, the means that flowmeter detects as a kind of Industry Control, are widely used.In actual use, in order to ensure result of use, flowmeter often needs adjustment.And general flowmeter is all just carry out adjustment when dispatching from the factory or installing.After installation, if in use need adjustment, flowmeter is then needed to remove adjustment, so obvious cumbersome, even if some specific calibration equipment can carry out adjusting and measuring on line by wire communication mode flow meter, if but under flowmeter is mounted in complex environment, such adjustment mode is also inconvenient.Therefore, need to provide a kind of flowmeter adjustment system, just can easily carry out adjustment by flow meter without the need to dismounting flowmeter.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of mobile phone adjustment system of industrial flow meter, coordinates pointer panel flow meter to carry out wireless adjustment by smart mobile phone, easy to use, reduces adjustment cost.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of mobile phone adjustment system of industrial flow meter, comprise flowmeter pointer panel, flowmeter internal circuit and mobile phone adjustment client, described flowmeter internal circuit is by Hall angular transducer, single-chip microcomputer, 24mA electric current loop module and GPRS module composition, the signal output part of described Hall angular transducer is connected to the signal input part of single-chip microcomputer, the control end of described single-chip microcomputer is connected to 24mA electric current loop module, described 24mA electric current loop model calling is to far-end computer, the output terminal of described single-chip microcomputer is connected to GPRS module, described GPRS module is connected with mobile phone adjustment client wireless.
In technique scheme, described mobile phone adjustment client is built-in with Android system, installs flowmeter adjustment software.
Principle of work of the present invention is: the pointer in described flowmeter pointer panel is along with the magnetic patch rotation in flowmeter, and the angle that magnetic patch rotates is determined by the size of flow, the actual size of pointer actual instruction flow.The angle that magnetic patch rotates is obtained by the Hall angular transducer in flowmeter electronics simultaneously, formation differential analog signal exports, single-chip microcomputer is converted to digital signal by the difference AD carried differential analog signal, and through algorithm process, drive 24mA electric current loop module output current to far-end computer according to digital signal, obtain digital stream value by computer sampling.The smart mobile phone of adjustment software is installed, coordinates the pointer instruction in pointer panel, at any time can by the GPRS module in flowmeter electronics, control single chip computer carries out parameter correction, ensures that the digital stream value that computing machine obtains accurately reflects actual flow.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. the present invention is by GPRS agreement, adopts smart mobile phone flow meter to carry out wireless adjustment, adjustment in the visual range that adjustment personnel can be installed at flowmeter, dismounting when avoiding flowmeter adjustment or communication connection, very easy to use.
2. the present invention only needs to install designated software on any a smart mobile phone and gets final product adjustment, does not need extra adjustment instrument, greatly reduces adjustment cost.
3. smart mobile phone adjustment software application friendly interface of the present invention, only need simple training, any one has the people of smart mobile phone use experience can grasp calibration procedures very soon, and generally all carries with due to smart mobile phone, and the adjustment of flowmeter can be carried out at any time.
