The communication device 1 can be applied to communication among a plurality of control devices, for example, when the communication device 1 is applied to the field of industrial automation, the communication device 1 can be used for automatic control signal transmission between devices of two processes on an industrial automation pipeline. Taking an OLED glass production line as an example, the whole process may include the steps of paper picking and loading, separation, grinding, cleaning, inspection, packaging, and the like, the devices in each step are controlled by individually programmed control devices, and the communication device 1 may be used to complete the communication between different control devices, so as to realize the online control of the communication between different devices (for example, to realize the online control between the inspection device in the inspection step and the packaging device in the packaging step).
In some embodiments, as shown in fig. 1, the communication device 1 may be a relay, the switch controller 11 may be a relay coil, and the control switch 12 may be a normally open contact. The relay coil and the normally open contact are arranged oppositely, the first control device 2 is used for controlling the corresponding first device, and the second control device 4 is used for controlling the corresponding second device. When online control of the first device and the second device is required, a communication signal, which is substantially a voltage applied to the relay coil (which may be a level signal, for example), to energize the relay coil, may be output by the first control device 2 to the relay coil of the relay. The relay coil may be energized upon receipt of a communication signal to close the normally open contact.

When the paper taking and feeding device and the separating device are required to be controlled on line, the PLC of the paper taking and feeding device can output communication signals to the relay coil, and the relay coil is electrified to close the normally open contact. After the normally open contact is closed, the second power supply 5 can supply power to the PLC of the separation equipment to ensure that the PLC of the separation equipment works normally, so that the PLC of the separation equipment can control the separation equipment to work normally. By analogy, the PLC of the separating device controls the PLC of the grinding device to normally work through another relay, the PLC of the grinding device controls the PLC of the cleaning device to normally work through another relay, the cleaning device controls the PLC of the checking device to normally work through another relay, the checking device controls the PLC of the packaging device to normally work through another relay, and the packaging device controls the PLC of the paper taking and feeding device to normally work through another relay.
