Description
Technical field
The utility model relates to Industry Control, WIFI wireless transmission applied technical field, especially a kind of place remote WIFI radio transmitting device based on PLC.
Background technology
At present, without the PLC industrial control system of data display function, system operation situation can not real time inspection; When needs are checked, need external equipment and carry out wired connection, wasting time and energy; With the PLC industrial control system of Presentation Function, data check that mode is single; Traditional industry display screen, at some Special field bad environments, restricted lifetime, and cost is high; When operational monitoring personnel need in place remote Monitoring Data time, on-the-spot service data cannot be obtained in time.
Utility model content
The operation present situation of existing equipment is difficult to meet fast-developing scientific-technical progress demand, in order to solve above-mentioned Problems existing, the utility model proposes a kind of place remote WIFI radio transmitting device based on PLC, by the free PORT COM (RS-485/RS-232) of PLC, with regulation protocol form by the conventional operation data upload of system to this device, carry out Data Analysis by the MCU that this device is built-in and be forwarded to built-in WIFI module.Meanwhile, the AP (wireless access points) through being provided with at the scene realizes the networking transport of data, and this remote data is backed up to the server arranged.System guardian only need by installing corresponding APP on the handheld terminal of networking, the service data of system can be realized to be presented at handheld terminal in real time, the long-range real-time running state checking system equipment, achieves the remote informationization monitoring of conventional P LC control system.
For realizing this technical purpose, the technical solution adopted in the utility model is: a kind of place remote WIFI radio transmitting device based on PLC, comprises MCU module, WIFI module and power module; Described MCU module connects the free PORT COM of PLC by RS-485 or RS-232 bus, and WIFI module connects MCU module by UART; Described MCU module is all connected with power module with WIFI module; The WIFI signal that described WIFI module is launched by the external antenna be connected with WIFI module and on-the-spot AP wireless connections.
As further technical scheme of the present utility model: described MCU module is the MCU module being provided with two UART ports; Described power module is outside DC24V power supply.
Compared with prior art, the utility model has following beneficial effect: should based on the place remote WIFI radio transmitting device of PLC, WIFI Radio Transmission Technology is introduced industrial control field, realize the strange land teletransmission of equipment operating data, greatly improve scientific and technological content and the monitoring means of traditional industry control system;
APP Application and Development, realizes the patrolled function of handheld terminal;
Multiple terminals can being realized check whenever and wherever possible, without the need to only relying on on-the-spot display device, saving the operating cost of display device.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 is overall system architecture schematic diagram;
Wherein: 1.MCU module; 2.WIFI module; 3. power module; 4. on-the-spot AP.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Figure of description 1, in the utility model embodiment, a kind of place remote WIFI radio transmitting device based on PLC, comprises MCU module 1, WIFI module 2 and power module 3; Described MCU module 1 connects the free PORT COM of PLC by RS-485 or RS-232 bus, and WIFI module 2 connects MCU module 1 by UART; Described MCU module 1 is all connected with power module 3 with WIFI module 2; The WIFI signal that described WIFI module 2 is launched by connected external antenna and on-the-spot AP4 wireless connections.
As further technical scheme of the present utility model: described MCU module 1 is for being provided with the MCU module of two UART ports.Described power module 3 is outside DC24V power supply.
Action principle of the present utility model is: with the MCU of 2 UART ports for core, and a road realizes the data communication with PLC, and a road realizes the data transmission of WIFI module; Adopt DC24V to power (customizable), the scene that is beneficial to is consistent, without the need to arranging power supply in addition with PLC; APP adopts Android platform, increases income easy-to-use; Based on WiFi technology, break the limitation of traditional data monitoring, can " whenever and wherever possible " realize.
WIFI radio transmitting device is powered by outside DC24V, from the Free of PLC with RS-485/RS232 according to certain protocol requirement, realize plc data collection to device interior, realize Data Analysis through MCU and be transmitted to built-in WIFI sending module, and with the form of WIFI wireless transmission by AP on-the-spot for data in situ access, ensure that the networking path of field data.
See Fig. 2, the transmission data of on-the-spot PLC access on-the-spot AP through WIFI module, after Internet Transmission, back up to the server end of long-range setting, by installing APP on handheld terminal, and the form of access services device realizes monitoring at any time the wireless strange land of on-the-spot PLC system service data.
To those skilled in the art, but the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
