In order to achieve the above object, a kind of PLC wireless control system based on Bluetooth transmission of the utility model, it is characterized in that, comprise the serial line interface be bi-directionally connected successively, serial ports modular converter and the bluetooth module that are arranged on PLC side, wherein bluetooth module is SPP-C serial port adapter module; Also comprise mobile terminal and built Bluetooth module thereof.
Described serial ports modular converter is chip SN75716.
Described mobile terminal is the one in mobile phone, notebook computer, panel computer.
Described PLC is siemens PLC, and the serial line interface of PLC side, serial ports modular converter and bluetooth module, all by the power taking of PLC pin, do not need to connect external power source in addition.
The utility model achieves programmes and controlled in wireless to PLC on mobile terminals, and do not need serial port drive, cost is low, and cost performance is high, easy to carry.Program debug is simple, does not need repetition swapping process, reduces interface wearing and tearing.
Accompanying drawing explanation
Fig. 1 is the model calling figure of the utility model embodiment 1;
Fig. 2 is the circuit diagram of the utility model embodiment 1PLC side;
Fig. 3 is the level shifting circuit figure in the utility model embodiment 1.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1
As shown in Figure 1, PLC adopts siemens PLC, with its be connected be RS485 interface, serial ports modular converter SN75716 and bluetooth module SPP-C successively, be two-way communication each other.Mobile terminal side comprises built-in bluetooth module, and two bluetooth modules all include antenna.
Terminal sends data procedures:
Mobile terminal with Bluetooth function sends wireless data by built Bluetooth module antenna, as Fig. 2, received by the Bluetooth antenna of coupling SPP-C, data after process deliver to SN75716 by 1 human hair combing waste, No. 8 pins being sent to RS485 after SN75716 receives and processes send into PLC inside, the data completing a terminal and PLC are transmitted, and realize mobile terminal and programme by controlled in wireless PLC or to PLC.
Terminal receives data procedures:
PLC sends data to 3 pin of RS485, be transferred to SN75716 process afterwards, and the 1k resistance through connecting delivers to 2 pin of SPP-C, send to mobile terminal after bluetooth module process, complete the receiving course of data after the bluetooth module reception data that mobile terminal is built-in, data can show on the screen of the mobile terminal.
6 pin of RS485 provide 5V power supply for this module, and because bluetooth module is that 3.3V powers, so add the level shifting circuit as Fig. 3, level conversion is realized by AMS1117 chip.
Embodiment 2
PLC adopts Mitsubishi Fx2N, with its be connected be RS422 interface, serial ports modular converter SN75716 and bluetooth module SPP-C successively, be two-way communication each other.Mobile terminal side comprises built-in bluetooth module, and two bluetooth modules all include antenna.
Terminal sends data procedures:
Mobile terminal with Bluetooth function sends wireless data by built Bluetooth module antenna, received by the Bluetooth antenna of coupling SPP-C, data after process deliver to SN75716 by 1 human hair combing waste, after SN75716 receives and processes, be sent to RS422 then send into PLC inside, the data completing a terminal and PLC are transmitted, and realize mobile terminal and programme by controlled in wireless PLC or to PLC.
Terminal receives data procedures:
PLC sends data to RS422, be transferred to SN75716 process afterwards, then deliver to 2 pin of SPP-C, send to mobile terminal after treatment, complete the receiving course of data after the bluetooth module reception data that mobile terminal is built-in, data can show on the screen of the mobile terminal.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also comprises the technical scheme be made up of above technical characteristic combination in any.
