Bridge system, device and control method for remote control sequence/parallel device

A control device, a system and a processing method thereof, and particularly relates to a bridge system, device and control method for a remote control sequence/parallel device.

With the rapid development of the Internet, many electronic devices have also joined the remote control function. For example, a player with audio and video functions can use the network to achieve the purpose of remote playback. Unreliable transmission characteristics for the network can be applied to image transmission or sound transmission. It is acceptable for the user to lose the video data of a small segment. But not all electronic devices are suitable for remote control. This is because there are uncertainties in the protocols and environments of network transmission. In other words, network packets can be left in the process of transmission. Therefore, remote electronic devices may receive incomplete control commands.

In the event of a packet loss, the remote electronic device may experience erroneous operation or continuous waiting behavior. The wrong operation of electronic equipment, small may cause the power consumption of the machine, and large may cause public security accidents. Especially for the serial port and the parallel port, the control interface requires a complete control command to drive correctly. Therefore, an incomplete control command is bound to cause erroneous control or damage to the electronic device of the aforementioned interface.

In addition, the mobile computer can achieve the purpose of being thin and light. The removable computer may be a mobile phone or a tablet. The developer of the development removes the type of external interface as much as possible. Therefore, a general mobile computer cannot control external peripheral devices through a wired manner. For example, a dot matrix printer with an RS-232 barcode scanner or a parallel serial port (Parallel Port). As mentioned above, the ports are not set in the mobile computer, and the driving mode of the port is not further defined in the operating system. Therefore, the removable computer cannot directly drive the peripheral device.

Please refer to FIG. 1 , which is a schematic diagram of the system architecture of the present invention. The bridge system of the remote control sequence/parallel device of the present invention includes a mobile device 110, a wireless network base station 120 (Access Point, AP for short), a bridge device 130, a target device 140, and an external device 150. The type of mobile device 110 can be, but is not limited to, a notebook, a tablet, or a mobile phone.

The mobile device 110 of the present invention has a processor 111, a storage unit 112, a display unit 113, and a first network transmission unit 114. The processor 111 is electrically connected to the storage unit 112, the display unit 113, and the first network transmission unit 114. The processor 111 transmits a manipulation command to the wireless network base station 120 through the first network transmission unit 114, or receives a response message from the wireless network base station 120.

The storage unit 112 stores the mediation program 115. The processor 111 will start running the mediator 115 after startup. In addition to the search for the bridging device 130, the sending of the manipulation command, or the receipt of the response message, the intermediation program 115 performs pre-processing for disassembling the aforementioned manipulation command. The mediator 115 can be a stand-alone application or can be built into the Operation System. The processor 111 dispatches the mediation program 115 according to the category information sent by the bridge device 130 for establishing an address space and a plurality of connection channels. The mediator 115 uses the address space and the plurality of connection channels to simulate the transmission mode of the bus bar between the target device 140 and the personal computer. The display unit 113 is configured to display an operation interface and related information of the mediation program 115 or other applications.

When the mobile device 110 issues a manipulation command (or related processing material) to the target device 140, the mediation program 115 performs segmentation processing on the manipulation command. The mediator 115 of the present invention segments the manipulation commands according to the number of connection channels. Therefore, the mediator 115 will output the same number of segmentation results as the wire channel. The mediator 115 further obtains each corresponding data offset (offset) according to the segmented manipulation command.

In order to facilitate the description of the segmented manipulation commands (or manipulation data), each part of the division is defined as a sliced partition. The mediator 115 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 wireless network base station 120.

In addition to being electrically connected to the target device 140 and the wireless network base station 120, the bridge device 130 can also selectively connect the external device 150. The wireless network base station 120 is configured to communicate network packets transmitted by the mobile device 110 and the bridge device 130. The wireless network base station 120 has a wireless network transmission unit 121 and a first network interface 122. When the wireless network base station 120 receives the network packet from the mobile device 110 through the wireless network transmission unit 121, the wireless network base station 120 sends the network packet to the bridge device through the first network interface 122. 130. If the wireless network base station 120 receives the network packet from the bridge device 130, the wireless network base station 120 transmits the network packet to the mobile device 110.

The bridging device 130 includes a second network interface 131, a third network interface 132, a heterogeneous device interface 133, and a processing unit 134. The processing unit 134 is electrically connected to the second network interface 131, the third network interface 132, and the heterogeneous device interface 133. The first network interface 122 is electrically connected to the second network interface 131. The second network interface 131 is configured to receive a network packet from a manipulation command of the mobile device 110 or to send a response message to the wireless network base station 120. The third network interface 132 is for connecting to the external device 150, and the external device 150 may be another bridge device 130 or a personal computer. The processing unit 134 determines that the incoming first network packet does not belong to the bridge device 130, and the processing unit 134 forwards the first network packet through the third network interface 132.

The heterogeneous device interface 133 is connected to the control port 141 of the target device 140. The type of the heterogeneous device interface 133 is a serial port or a parallel port. The type of control unit 141 corresponds to the heterogeneous device interface 133. The bridging device 130 of the present invention can have a single serial serial port or a parallel serial port, or a serial serial port and a parallel serial port can exist at the same time. The processing unit 134 combines the network packets carrying the manipulation commands and obtains manipulation commands.

The bridging device 130 receives the corresponding first network packet. The processing unit 134 determines whether the order of the received first network packet is correct according to the data offset sequence recorded in the connection channel. The processing unit 134 reassembles the first network packet according to the connection channel and the data offset. The processing unit 134 of the bridge device 130 drives the target device 140 to perform corresponding operations in accordance with the manipulation command.

In order to clearly illustrate the control of the target device 140, please refer to FIG. 2, which is an operation transmission method of the present invention, including the following steps: Step S211: electrically connecting the bridge device to the wireless network base station and Target device: Step S212: The mobile device runs a mediation program, and the mediation program searches for the bridge device in the network; Step S213: After the bridge device receives the device search command, the bridge device returns the identification information; Step S214: The mobile device receives the identification of the bridge device Information, used to set the address space and multiple connection channels; Step S215: The mobile device segments the manipulation commands according to the address space and the connection channels, and encapsulates each segmentation result into the first network. Packet S216: the mobile device sends the first network packet to the wireless network base station and the bridge device through the network; step S217: the bridge device reassembles according to the sequence of the connection channels of the first network packets to obtain Manipulating the command; step S218: the bridge device forwards the manipulation command to the target device; step S219: the target device performs the operation Controlling the command and outputting the response message to the bridge device; step S220: the bridge device segments the response message according to the number of connection channels, and encapsulates the result of each segment to output a plurality of second network packets; Step S221: Sending the second network packets to the mobile device; and step S222: the mobile devices combine according to the order of the second network packets, and obtain corresponding response messages.

First, after the mobile device 110 is booted, the mobile device 110 will begin executing the mediator 115. The broker 115 searches through the first network transmission unit 114 for the presence of the bridge device 130. For the local area network, the mediator 115 can ask whether it is broadcast through the network. There is a bridge device 130. For the Internet, the mediator 115 can communicate via a known IP Address. Please refer to FIG. 3A and FIG. 3B simultaneously, which are respectively schematic diagrams of the operation of the present invention.

When the bridge device 130 receives the device search command, the bridge device 130 returns corresponding identification information. The serial number of the information recording bridge device 130, the number of serial ports, the electronic device, or the model of the bridge device 130 are identified. After the mobile device 110 receives the identification information, the mobile device 110 can generate an address space and a plurality of connection channels according to the identification information.

The memory size of the address space is determined according to the type of the target device 140. The number of connection channels can be determined according to the target device 140, or preset to a fixed number. The address space is used to simulate the memory space of the target device 140 when it is connected to the mobile device 110. Because the target device 140 of the present invention is connected to the mobile device 110 through the network, it is required to generate a corresponding address space in the mobile device 110 to provide the mobile device 110 for address access.

When the mobile device 110 issues a manipulation command (or manipulation data) to the target device 140, the mediation program 115 performs segmentation processing on the manipulation command. The mediator 115 of the present invention segments the manipulation commands according to the number of connection channels. Therefore, the mediator 115 will output the same number of segmentation results as the wire channel. The mediator 115 further obtains each corresponding data offset (offset) according to the segmented manipulation command. Since the order in which each data offset is transmitted is controlled, it can be ensured that both parties (i.e., mobile device 110 and target device 140) can acknowledge the order of reception. The calculation of the data offset can be implemented in a hardware manner, and the speed of the hardware processing is more efficient than the speed of the software layer parsing.

Then, after the wireless network base station 120 receives the first network packet, the wireless network base station 120 sends the first network packet to the bridge device 130. The bridging device 130 decides to reassemble the first network packet or forward the first network packet to the external device 150 according to the content of the first network packet. The bridging device 130 combines the first network packets and obtains manipulation commands. The bridge device 130 drives the connected target device 140 in accordance with the manipulation command.

After the target device 140 performs related operations according to the manipulation command, the target device 140 generates a response message after the operation. Target device 140 transmits a response message to bridge device 130. The bridging device 130 performs the foregoing segmentation processing on the response message and obtains a plurality of second network packets. The bridging device 130 retransmits the second network packet to the wireless network base station 120, and The wireless network base station 120 transmits to the mobile device 110. After the mobile device 110 receives the second network packet, the mobile device 110 reassembles the second network packet and obtains a corresponding response message.

In addition to the aforementioned manipulation commands and data transmission, the present invention can perform the same segmentation and transmission processing for the interrupt request. The present invention can be used to transmit various interrupt requests (IRQs) through different connection channels. With the transmission method described above, the order in which the target device 140 receives the interrupt request can be ensured. Therefore, the target device 140 can perform corresponding processing according to the correct interrupt request.

The present invention provides a bridge system, device and control method for a remote control sequence/parallel device, so that a device that does not have a serial serial port or a parallel serial port can implement the operation of the corresponding device by using the present invention, and does not need to perform the bottom layer of the mobile device 110. The corresponding change.

While the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. The patent protection scope of the invention is subject to the definition of the scope of the patent application attached to the specification.
