Description
Technical field
The utility model relates to electronic information technical field, is specifically related to a kind of isolator that can be carried out data transmission by WIFI.
Background technology
Isolator has the control loop of protection subordinate; Slacken the impact of neighbourhood noise on test circuit; Suppress common ground, frequency converter, solenoid valve and not clear pulse to the interference of equipment; Subordinate equipment is had to the function of pressure limiting, volume stream, be the loyalty protection of transmitter, instrument, frequency converter, solenoid valve PLC/DCS input and output and communication interface simultaneously.Its principle of work, first the signal of transmitter or instrument, by semiconductor devices modulating transformation, then carries out isolation conversion by light sensation or magnetic strength device, and then carry out demodulation and switch back to original signal before isolation, isolation processing is carried out to the power supply of signal after isolation simultaneously.Ensure the signal after conversion, power supply, between definitely independent.
The utilization of signal isolator in automated system is extensive and importance is pure, but its Installation and Debugging all need wiring, and installation and maintenance are all inconvenient.Now signal isolator commercially does not possess autonomous judgement, can not meet the requirement of cloud robotization.
Summary of the invention
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, the isolator that can be carried out data transmission by WIFI reasonable in design, easy to use, the difficult problem of wiring is solved by WIFI wireless transmission, and there is the ability judged voluntarily, achieve cloud robotization.
For achieving the above object, the technical solution adopted in the utility model is: it comprises CPU central processing module, power module, WIFI communication module, photoelectric isolation module, input signal processing module, output signal processing module, described power module respectively with WIFI communication module, CPU central processing module is connected with photoelectric isolation module, described input signal processing module is connected with photoelectric isolation module, photoelectric isolation module is connected with output signal processing module, output signal processing module is connected with CPU central processing module, CPU central processing module and WIFI communication model calling.
Principle of work of the present utility model: isolator is by input end received current or voltage signal, signal will carry out modulation treatment through input signal processing module to signal, for Phototube Coupling, output signal processing module is sent into by the signal after photoelectric isolation module, the original signal that output signal processing module will be returned the data demodulates after Phototube Coupling before isolation modulation, then exports original signal; Output signal processing module simultaneously and the original signal after demodulation is sent to CPU central processing module, signal is carried out a series of process such as A/D conversion and becomes digital signal by CPU central processing module, the digital signal handled well is sent to WIFI data acquisition module by WIFI communication module, and data are sent to cloud data server by WIFI data acquisition module again; Simultaneously whether isolator also the data value of Real-Time Monitoring collection can be in normal condition, once the data of data acquisition exceed set limit value, isolator will generate a warning automatically, and warning is sent to WIFI data acquisition module by the very first time, it can first be the generation seeing alert data that WIFI data acquisition module pushes data into cloud data server user again.
After adopting said structure, the utility model beneficial effect is: a kind of isolator that can be carried out data transmission by WIFI described in the utility model, the difficult problem of wiring is solved by WIFI wireless transmission, and there is the ability judged voluntarily, achieve cloud robotization, and it is simple to have structure, arrange rationally, the advantages such as cost of manufacture is low.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Referring to as shown in Figure 1, the technical scheme of this embodiment is: it comprises CPU central processing module 1, power module 2, WIFI communication module 3, photoelectric isolation module 4, input signal processing module 5, output signal processing module 6, described power module 2 respectively with WIFI communication module 3, CPU central processing module 1 is connected with photoelectric isolation module 4, described input signal processing module 5 is connected with photoelectric isolation module 4, photoelectric isolation module 4 is connected with output signal processing module 6, output signal processing module 6 is connected with CPU central processing module 1, CPU central processing module 1 is connected with WIFI communication module 3.
The principle of work of this embodiment: isolator is by input end received current or voltage signal, signal will carry out modulation treatment through input signal processing module 5 pairs of signals, for Phototube Coupling, output signal processing module 6 is sent into by the signal after photoelectric isolation module 4, the original signal that output signal processing module 6 will be returned the data demodulates after Phototube Coupling before isolation modulation, then exports original signal; Output signal processing module 6 simultaneously and the original signal after demodulation is sent to CPU central processing module 1, signal is carried out a series of process such as A/D conversion and becomes digital signal by CPU central processing module 1, the digital signal handled well is sent to WIFI data acquisition module 7, WIFI data acquisition module 7 and again data is sent to cloud data server by WIFI communication module 3; Simultaneously whether isolator also the data value of Real-Time Monitoring collection can be in normal condition, once the data of data acquisition exceed set limit value, isolator will generate a warning automatically, and warning is sent to WIFI data acquisition module 7, WIFI data acquisition module 7 by the very first time, and to push data into cloud data server user again can first be the generation seeing alert data.
After adopting said structure, this embodiment beneficial effect is a kind of isolator that can be carried out data transmission by WIFI described in this embodiment, the difficult problem of wiring is solved by WIFI wireless transmission, and there is the ability judged voluntarily, achieve cloud robotization, and it is simple to have structure, arrange rationally, the advantages such as cost of manufacture is low.
