A control system for a peripheral device, and more particularly to a control system for implementing multi-person operation in a single machine.

With the rapid increase in computer performance, computers can run at least one virtual machine (Virtual Machine). The hardware resources of each virtual machine can also be set by the user. And each virtual machine can run its own separate operating system. For example, a computer has a virtual machine A and a virtual machine B.

Please refer to Figure 2, which is a schematic diagram of the new control flow. The control flow of the present invention includes the following steps: Step S210: The main control computer is electrically connected to the first peripheral device; Step S220: the main control computer network is connected to the bridge device, and the bridge device is electrically connected to the second peripheral device; Step S230: Generating at least one virtual machine in the host computer and running the virtual operating system on the virtual machine; Step S240: The virtual machine program monitors the network transmission of the virtual machine, and forwards the virtual network interface of the virtual machine to the first network interface. Step S250: the first operation command is sent or received by the main control computer to the first peripheral device. The response message returned by the first peripheral device; step S260: the virtual machine converts the received second operation command into the first network packet; and step S270: the virtual machine interfaces with the first network through the virtual network interface The second peripheral device sends the first network packet with the second operation command; step S280: the second peripheral device executes the second operation command, and outputs a response message to the bridge device; step S290: the bridge device according to the number of connection channels The response message is segmented, and the result of each segment is converted and output as a plurality of second network packets; and step S300: the second network packet is sent to the virtual machine.

The main control computer 110 is connected to the bridge device, and the bridge device 120 is electrically connected to the second peripheral device 140. The user A can operate the first peripheral device 130 through the physical control interface 113. The first peripheral device 130 may also return a response message to the host computer 110 after completing the operation, as shown in FIG. 3A.

At least one virtual machine 300 is generated in the master computer 110, and a respective virtual operating system 310 is run on each virtual machine 300. The virtual machine program 153 dispatches hardware resources to the virtual machine 300 according to the settings of the user. Please refer to Figure 3B, which is a schematic diagram of the new virtual machine list. For example, the virtual machine program 153 monitors the network transmission of each virtual machine 300 and calls the first network interface 114 to the host computer 110 and each virtual machine 300 in a timely manner. The virtual machine 300 includes at least a virtual operating system 310, a virtual network interface 320, and a virtual control interface 330.

After the virtual machine 300 is booted, the virtual machine 300 loads the virtual operating system 310. The virtual operating system 310 will run the intermediaries 152 in conjunction. The mediation program 152 can be a standalone application or can be built into the virtual operating system 310. The mediator 152 is used by the virtual network interface 320 and the first network interface 114 to detect the presence of the bridge device 120. After the bridge device 120 receives the device search command, the bridge device 120 returns the corresponding identification resource. News. The serial port type of the information recording bridge device 120, the number of serial ports, the type of the second peripheral device 140, or the model number of the bridge device 120 are identified.

At the same time, the intermediation program 152 is used to establish an address space and a plurality of connection channels according to the identification information. The size of the address space is determined according to the type of the second peripheral device 140. The number of connection channels may be determined according to the second peripheral device 140, or may be preset to a fixed number. The address space is used to simulate the memory space of the second peripheral device 140 when the virtual machine 300 is connected. The intermediation program 152 is used to simulate the transmission mode of the bus bar between the second peripheral device 140 and the host computer 110 through the address space and the plurality of connection channels.

The user B can log in to the virtual machine 300 through the terminal device 160 and operate the related hardware of the virtual operating system 310. User B can see the presence of the second peripheral device 140 from the virtual operating system 310, as shown in FIG. 4A. In Fig. 4A, the solid line represents the connection of the physical line, and the dotted line represents the connection of the virtual line. When the user B issues a second operation command (or operation data) to the second peripheral device 140 through the virtual machine 300, the mediation program 152 performs segmentation processing on the operation command, as shown in FIG. 4B, which is Schematic diagram of the transmission process of the second operation command of the present invention.

In the present invention, the mediation program 152 performs segmentation processing of the network packet on the operation command according to the number of connection channels. The mediator 152 therefore outputs the same number of segmentation results as the wire channel. The mediator 152 further obtains each corresponding data offset (offset) based on the segmented operation command. Since the order in which each data offset is transmitted is controlled, it can be ensured that both the transmitting and receiving parties (virtual machine 300 and second peripheral device 140) can confirm the order of reception. This method can be implemented in a hardware manner, and the speed of hardware processing is more efficient than the speed of software layer analysis.

In order to facilitate the description of the segmented operation command (or manipulation data), each part of the division is defined as a sliced partition block. The mediator 152 converts the sliced partition block and the corresponding data offset into the first network packet sequentially through the connection channel, and sends the first network packet to the bridge device 120.

The bridging device 120 reassembles the first network packet and obtains a corresponding second Operational commands. The bridge device 120 transmits a second operational command to the second peripheral device 140. After the second peripheral device 140 executes the second operation command, the second peripheral device 140 returns a corresponding response message to the bridge device 120. The bridging device 120 converts the response message into a plurality of second network packets according to the aforementioned segmentation process. The bridging device 120 transmits the second network packet to the corresponding virtual machine 300.

The control system provided by the present invention for realizing multi-person operation in a single machine can reduce the installation cost and maintenance cost of the computer, and can provide multiple users to operate the respective peripheral devices on the same computer. Different users can operate the associated virtual operating system 310 or control the second peripheral device 140 to which the respective virtual operating system 310 belongs.
