As Figure 1 shown, the machine control device includes a host computer, an overcurrent protection unit, a signal acquisition unit, and a control unit. The signal acquisition unit is connected between the host computer and the machine. The machine includes a semiconductor manufacturing machine, and the machine is generally provided with a human-machine interface. The video signal acquired by the signal acquisition unit is the video signal of the machine human-machine interface. The machine human-machine interface is usually used to display and set various parameters reflecting the working state of the machine. Therefore, the working state of the machine can be obtained through the video signal acquired by the signal acquisition unit. In this embodiment, the signal acquisition unit adopts an IP KVM (multi-computer switcher), and the IP KVM can non-invasively acquire the video signal of the machine, avoiding affecting the normal operation of the machine. Non-invasive means that no software or hardware addition or deletion operations are required.

[0051] Specifically, in this embodiment, the host computer adopts a Mini PC. The host computer is externally provided with multiple types of interfaces, including two Thunderbolt4 interfaces, 2 Type A USB3.2 interfaces, 2 Type A USB2.0 interfaces, two HDMI2.0b interfaces, a PCIE interface, and an Ethernet interface with a transmission speed of 2.5 Gbps. In this embodiment, a first Ethernet interface and a second Ethernet interface with a transmission speed of 1000 Mbps are expanded through the PCIE interface. The first Ethernet interface is Figure 2The shown Ethernet Interface1, the second Ethernet interface, namely Figure 2 the shown Ethernet Interface2. The host computer is connected to the IP KVM through the first Ethernet interface to receive video signals. The second Ethernet interface is used as an external expansion interface for the machine control device to adapt to different application requirements. The first Ethernet interface and the second Ethernet interface are connected to the PCIE interface through an FPC (Flexible Printed Circuit Board). The first Ethernet interface and the second Ethernet interface can be RJ45 interfaces. Figure 3 The figure shows a schematic diagram of the connection between the RJ45 interface and the FPC. The connection form of the RJ45 interface to the PCIE interface through the FPC is consistent with the prior art.

[0052] The external interfaces of the IP KVM include an HDMI OUT interface, two USB interfaces for control, an HDMI IN interface for video signal access, a DB9 interface for debugging, and an RJ45 interface. The RJ45 interface is connected to the above-mentioned first Ethernet interface. The overcurrent protection unit and the control unit are both adaptively connected to the host computer. The specific implementation manners and connection forms of the overcurrent protection unit and the control unit can refer to the following description.

[0053] Further, the overcurrent protection unit includes switching devices Q5, Q6, resistors R46, R47, R48, R49, R50, R51, and capacitor C98, where

[0067] Specifically, Figure 2 Relay1 in Fig. represents the first output sub-unit. The first output sub-unit is used to control the IPKVM to switch between the remote control mode and the local control mode. Figure 7 Fig. shows a schematic diagram of an embodiment of the first output sub-unit, as Figure 7As shown, the first pin of relay K1 is connected to the IP KVM, i.e., the signal acquisition unit, and the third pin of relay K1 is connected to the output terminal of the buck unit to access the 5V operating voltage. The zener diode ZD3 is used to clamp the voltage across the coil of relay K1. The single-chip microcomputer controls the gate voltage of NMOS transistor Q1 through GPIO5 pin to control the conduction state of NMOS transistor Q1, and controls the energization state of relay K1 by controlling the conduction state of NMOS transistor Q1, so as to control the working mode of the IP KVM.

[0071] Specifically, the second output sub-unit is used to externally provide a normally open relay output signal and a normally closed relay output signal. Figure 2 Relay2 in it represents the second output sub-unit. Figure 8 The figure shows a schematic diagram of an embodiment of the second output sub-unit, as Figure 8 As shown, the first pin of relay K2 is connected to the output terminal of the buck unit to access the 5V operating voltage.
