[0048] The master device 1 includes a first control module 11, and the slave device 2 includes a second control module 21;

[0049] The first control module 11 includes a first routing unit 111, and the second control module 21 includes a second routing unit 211;

[0054] Embodiment 2

[0055] This embodiment provides a master-slave control system, which is a further improvement on Embodiment 1.

[0056] In an implementable solution, as Figure 2 shown in the structural schematic diagram of the master-slave control system of this embodiment, the master device 1 further includes a first power-on / off button 12 electrically connected to the first control module 11;

[0057] The first power-on / off button 12 is used to turn on and / or turn off the master device 1 and send a first power-on / off signal to the first control module 11;

[0058] The first control module 11 is used to receive the first power-on / off signal to drive the master device 1 to perform power-on and power-off actions;

[0059] The first control module 11 is further used to send the first power-on / off signal to the second control module 21 to drive the slave device 2 to perform power-on and power-off actions.

[0060] Specifically, after the control board A is powered on, it starts to search for and connect to the control board B and enters the standby state. The first power on / off button is connected to the DI (Digital Input)-A terminal of the control board A of the main device. After pressing the first power on / off button, the control board A detects the first power on / off signal corresponding to the first power on / off button, so that the main device performs the power on / off action; in addition, the first power on / off signal is transmitted to the slave device through the connection line between the first routing unit and the second routing unit, so that the slave device performs the power on / off action. The first power on / off signal is the button signal corresponding to the first power on / off button, including the first power on signal and the first power off signal.

[0061] In this solution, by setting the first power on / off button electrically connected to the first control module, the first control module receives the first power on / off signal corresponding to the first power on / off button to drive the main device to perform the power on / off action and sends the first power on / off signal to the slave device, so that the slave device performs the power on / off action, that is, the main device can realize the one-key switching of the power on / off state of the entire master-slave control system (the main device and the slave device), improving the convenience of controlling the power on / off state of the master-slave control system.

[0062] In an implementable solution, the slave device 2 further includes a second power on / off button 22 electrically connected to the second control module 21;

[0063] The second power on / off button 22 is used to turn on and / or off the slave device 2 and send out the second power on / off signal to the second control module 21;

[0064] The second control module 21 is used to receive the second power on / off signal to drive the slave device 2 to perform the power on / off action;

[0066] Specifically, after the control board B is powered on, it starts to search for and connect to the control board A and enters the standby state. The second power on / off button is connected to the DI-B terminal of the control board B of the slave device. After pressing the second power on / off button, the control board B detects the second power on / off signal corresponding to the second power on / off button, so that the slave device performs the power on / off action; in addition, the second power on / off signal is transmitted to the main device through the connection line between the first routing unit and the second routing unit, so that the main device performs the power on / off action. The second power on / off signal is the button signal corresponding to the second power on / off button, including the second power on signal and the second power off signal.

[0067] In this solution, by setting a second power-on / off button electrically connected to the second control module, the second control module receives a second power-on / off signal corresponding to the second power-on / off button to drive the slave device to perform a power-on / off action and sends the second power-on / off signal to the master device so that the master device performs a power-on / off action. That is, at the slave device side, the on / off state of the entire master-slave control system can be switched with one key, improving the convenience of controlling the on / off state of the master-slave control system.

[0068] In an implementable solution, the master device 1 further includes a first switching power supply 13 electrically connected to the first control module 11;

[0070] The slave device 2 further includes a second switching power supply 23 electrically connected to the second control module 21;

[0071] The second switching power supply 23 is used to convert external alternating current into direct current to supply power to the slave device.

[0072] Specifically, the external alternating current can use an AC (Alternating Current) 220V power supply, which is respectively converted into direct current through the first switching power supply to supply power to each component inside the master device and through the second switching power supply to supply power to each component inside the slave device. The first control module is electrically connected to the first switching power supply, making the first control module in a constantly powered-on state; the second control module is electrically connected to the second switching power supply, making the second control module in a constantly powered-on state. When both the master device and the slave device are connected to an external power supply and the connection line between the master and slave devices is in good condition, information interaction will occur between control board A and control board B through the connection line.

[0073] In this solution, by setting a switching power supply to convert external alternating current into direct current, it is convenient for the power supply needs of the master device and the slave device, ensuring the power supply safety of the master device and the slave device.

[0077] Among them, the first switch module includes a relay.

[0078] Specifically, when the control board A is in the standby state and the first power-on / off button is pressed, the control board A detects the first power-on signal. At this time, the first switch module is controlled to close, and the host computer is powered on and starts up. The host computer and the control board A complete the connection, and the main device end enters the self-check process. In addition, the first power-on signal is transmitted to the slave device end through the connection line.

In addition, the first power-off signal is transmitted to the slave device end through the connection line. The control board A receives the second power-off signal transmitted by the slave device end through the connection line, and the control process is similar and will not be elaborated here.

[0080] In this solution, by setting the first power-on / off module, the automatic control of the power-on / off state of the host computer is realized, and the convenience of controlling the power-on / off state of the main device is improved.

[0081] In an implementable solution, the first routing unit 111 is further configured to set the third address information corresponding to the host computer 15, and communicate with the host computer 15 according to the third address information.

[0087] Among them, the second switch module includes a relay.

[0088] Specifically, when the control board B is in the standby state and the second power-on / off button is pressed, the control board B detects the second power-on signal. At this time, the second switch module is controlled to close to supply power to the industrial computer, and the industrial computer and the control board B complete the connection, and the slave device enters the self-check process; in addition, the second power-on signal is transmitted to the master device end through the connection line; the control board B receives the first power-on signal transmitted by the master device end through the connection line, and the control process is similar and will not be elaborated here.

[0095] Among them, the plurality of drivers 26 are cascaded, and communication connections are established between the driver 26 of the first stage and the industrial computer 25, and between the driver 26 of the previous stage and the driver 26 of the next stage;
