Abstract
The invention discloses a technical method and device for achieving industrial-control multichannel IO wireless transmission by infrared through an infrared transmitting and receiving communication technology. The device comprises multichannel IO, a master, a slave, an address arrangement, an infrared transmitter and an infrared receiver. A wide-input-voltage mechanism is adopted to supply power, each device can be selectively set to be a master or slave through setting the master and the slave, and IO wireless transmission communication is achieved only in case of when the two devices separately serve as the master and the slave and addresses are consistent. A master side periodically transmits a transmission ready signal; a slave side receives the ready signal from the master, returns a ready signal and gets ready for transmission; after both the master and the slave receive the ready signals, both-way communication is started. Communication between the master and the slave adopts infrared codes and has checking, so that the interference resistance of infrared communication to environments is greatly improved. The method and the device are simple and easy, the problem that infrared bijection sensors can only achieve a single IO wireless transmission function in the past is effectively solved, and the method and the device are applicable to multiple occasions such as intelligent factories, intelligent home and short-range wireless control.
Description
Technical field
The present invention realizes the industry control multichannel IO technical method being wirelessly transferred and device by infrared communication technology, divides according to law of international patent classification chart (InternationalPatentClassification is called for short IPC) and belongs to electric department, electrical communication technology branch。Belong to technical field of telecommunications。
Background technology
At present, main communication modes is divided into wired and wireless；
Wherein, infrared communication technology is a kind of non-contact communication technology, has capacity of resisting disturbance strong, and information transmission is reliable, and low in energy consumption, cost is low, radiationless, it is easy to the advantage such as realize and can be encoded, thus being widely adopted。But current infrared communication is mainly applied to the point-to-point communication of equipment。And the information transmission majority of the I/O contact point such as PLC is by wired in Industry Control, or corresponding one an of I O point is wirelessly transferred sensing。And during for requiring that multichannel IO job information transmits, it is necessary to expend multiple being wirelessly transferred and sense reception device。
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of industry control multichannel IO adopting infrared communication and are wirelessly transferred skill。
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions:
The present invention includes: multichannel IO input, multichannel IO output, slave and address setting, infrared transmitter, infrared remote receiver；Also include adopting the IO of wide input voltage mechanism to power and control chip power supply；Described slave and address are arranged, and can pass through to arrange slave and select device to be arranged to main frame or from machine, only when two device respectively main frames with from machine and address consistent when realize IO and be wirelessly transferred；Described host side periodically sends and prepares transmission signal；Described receive, from machine termination, the preparation transmission signal that main frame sends after, return and get out signal, and carry out signal transmission and prepare；It is ready to after signal to start periodically both-way communication when slave all receives；Between described slave, communication adopts infrared coding, from tape verifying, substantially increases the infrared communication capacity of resisting disturbance to external environment condition。
Accompanying drawing explanation
Fig. 1 is technical solution of the present invention schematic diagram；Fig. 2 is the device conceptual scheme of the technology of the present invention；
Wherein in Fig. 2: 1 is wide pressure input power module, and 2 is infrared transmission module, and 3 is infrared receiving module, and 4 arrange module for apparatus of the present invention slave, and 5 arrange module for address, and 6 is multichannel IO input module, and 7 is multichannel IO output module。
Detailed description of the invention
As seen from Figure 2: the present invention includes multichannel IO input 6, multichannel IO output 7, slave 4 and address arrange 5, infrared transmitter 2, infrared remote receiver 3；Also include adopting the IO of wide input voltage mechanism to power and control chip powers 1。
Then when one of them device being arranged to main frame and working out address, main control chip send address code and ready-to-receive signal, sent by infrared emission end, the successful return signal to be received such as。If not receiving from machine feedback signal in certain time, then main frame periodically sends address code and ready-to-receive signal, until receiving return signal, configuration state display lamp is connection status, and display lamp length is bright, enters communications status, transmitting IO and encode signal, decoding receives I/O state；
Another device is arranged to from machine, and establishment address consistent with main frame can receive signal, having error signal in order to avoid receiving, improving anti-interference。From machine after the ready signal receiving the address coupling that host side sends, returning and get out signal, apposition display lamp is connection status, and display lamp length is bright, enters communications status, and decoding receives I/O state, transmits IO and encodes signal；
During coding information, through verification, coding, Phototube Coupling, main control chip performing corresponding multichannel IO input, during decoded information, through verification, decoding, Phototube Coupling, main control chip performing corresponding multichannel IO output, thus realizing being wirelessly transferred of multichannel industry control IO。
