Abstract

The present invention provides a network redundant switch device and a method thereof, and particularly a switch device connected with at least one electric device. The switch device comprises at least one serial interface to receive and transmit signal to the electric device; an operation module for interpreting data transmitted by the serial interface or transmitting the packets from the network interface to the serial interface. The switch device could make at least two copies of the signal from the electric device to at least two computer hosts for receiving data, so as to prevent loss of important data due to network connection failure of single receiving host. In a preferred embodiment, the switch device employs an operation module to operate on the signal to be transmitted to the electric device using a predetermined algorithm to determine if the device has the authorization for transmitting to the electric device.

Case No. 90111卯fi V. Invention Description (2) Traditionally, personal computers or electronic devices do not have connections to other personal computers. The standard serial port RS_232, in addition to the mechanical structure must be considered. The data transmission parameters and properties of the computer and peripheral devices must also be considered. The latter is generally referred to as the communication protocol. The communication protocol "Baud Rate", the number of data bits "Data Bu", the stop bit "Stop Bit", and the transmission of the communication protocol, the computer can communicate with the electronic device interface. Interpretation. However, the method by which such a standard communication protocol cannot be transmitted over a general local area network is that it must be transmitted through a conversion device. Interfaces, in terms of compatibility, such as compatibility, the consistency of the 包括 type includes the transmission rate % of the parity bits and so on. The device serializes the interface message through the serial. The information is stored in the network or after the electronic data is agreed to receive the network material, through the interface of the serial communication of the electronic network main machine, the conversion device, and then the packet, the host network main network Received this agreement. The purpose of the machine or the device will be received by the standard serial interface according to the established network and then through the network. When the opportunity first transmits the information to the network packet, it will be transmitted to the connected party's circuit interface, which is listed by the quasi-string of the network media. The network host material is packaged into the road media. The packet deserialization interface can be disconnected on the network, and the interface receives the sub-signal, and the package is sent to the network to send the data network communication; when the conversion is original, it is transmitted into the electronic device or may be caused by It will cause the electricity from the personal computer to be interpreted as the original appropriate network communication medium for the packet to be connected to the electronic device agreement, the device through the network data, and then according to the information sent to the receiving device to the personal computer host device can not Transmission 1271483 Case No. 90111926 Revision of the month V. Invention description (3) Handing over the information to the receiving personal computer, resulting in the loss of the data. SUMMARY OF THE INVENTION The object of the present invention is to provide a network backup conversion device and a method thereof, which can effectively prevent the loss of important data caused by a failure of a network connection of a single receiving host. To achieve the above object, the present invention develops a conversion device for connecting one or more electronic devices including: one or more serial input/output interfaces for receiving serial signals from an electronic device or transmitting Signal to the electronic device; a computing module for interpreting the data transmitted from the serial interface, and then packaging the data into a network protocol packet for transmission to the network interface, or vice versa for interpreting the packet from the network interface And then converted to a serial communication protocol to be transmitted to the serial interface; one or more network interfaces for receiving network signals or transmitting signals to the network; and copying signals from the electronic device into two copies according to the above device or After two or more copies, it will be sent to the network to give two or more computer hosts or electronic devices to receive data. In a preferred embodiment, the conversion means passes the signal to be transmitted to the electronic device for calculation to obtain the authority for transmission to the electronic device, and then transmits the signal to the electronic device. BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be apparent from the following detailed description of the preferred embodiments illustrated in the claims Figure 2 is a diagram showing the principle calculation of a feasible embodiment of the arithmetic module of the present invention.
