Embodiment 1

[0025] Such as figure 2 shown above figure 1 The hub 10 in includes: an infrared transmitting module 102, a processing module 104, and an infrared receiving module 106, wherein:

[0026] The infrared emitting module 102 is used to transmit an instruction to allow sending by using infrared rays, wherein the target address carried in the instruction to allow sending is the address of the first optical communication device that is currently allowed to forward data, so that only the first optical communication device responds to the permission Send instructions;

[0027] The infrared receiving module 106 is used to receive a data forwarding command in the form of infrared rays, wherein the data forwarding command is transmitted by the first optical communication device in response to the above-mentioned permission to send command when there is data to be forwarded, and the data forwarding command carries The target address is the second optical communication device;

[0028] T...

Embodiment 2

[0036] Such as Figure 5 As shown, in order to realize the transmission of the transmission permission instruction, the reception of the data forwarding instruction, and the forwarding data, the processing module 104 may include: a single-chip microcomputer 1042, an oscillator 1044, and a modulation and amplification circuit 1046, wherein:

[0037] The single-chip microcomputer 1042 is used to generate the permission to send instruction, and after the serialization of the generated permission to send instruction is input to the modulation amplifier circuit 1046; the data forwarding instruction received by the infrared receiving module 106 is demodulated and restored, and the data contained in the data forwarding instruction The data that needs to be forwarded and the target address (for example, the address of the second optical communication device) are serialized and input to the modulation amplifier circuit 1046; Instructions, instructing the infrared emitting module 102 to...

Embodiment 3

[0043] When the hub in Embodiments 1 and 2 above performs data communication with the optical communication device, the operation process performed by the hub is as follows: Figure 6 shown, including the following steps:

[0044] Step S602, using infrared rays to transmit an instruction to allow sending, wherein the target address carried in the instruction to allow sending is the address of the first optical communication device that is currently allowed to forward data, so that only the first optical communication device responds to the instruction to allow sending;

[0045] After the first optical communication device receives the permission to send instruction, it can judge that the permission to send instruction is sent to itself through the target address, and then, if there is data that needs to be forwarded, pass the data that needs to be forwarded through One or more data forwarding commands are transmitted to the hub in the form of infrared light.

[0046] Step S60...

Abstract

The invention discloses a concentrator, an optical communication device and a data communication method. The concentrator comprises an infrared emission module, a processing module and an infrared receiving module. The infrared emission module is used for emitting sending permission instructions through infrared rays, wherein a target address carried in the sending permission instructions is the address of first optical communication device being currently permitted to forward data so as to ensure that only the first optical communication device responds and is permitted to send the instructions, and each optical communication device is provided with an address; the infrared receiving module is used for receiving infrared-ray-form data forwarding instructions, and the data forwarding instructions are emitted aiming at the sending permission instructions under the condition that data need forwarding; and the processing module is used for modulating the data which are contained in the data forwarding instructions and need forwarding, and the data which are contained in the data forwarding instructions and need forwarding are emitted to a second optical communication device indicated in the target address in the data forwarding instructions through the infrared rays.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a hub (HUB), optical communication equipment, and a data communication method. Background technique [0002] Data communication technology combines computers with communication lines and equipment to realize the communication between people and computers, computers and computers, which not only greatly improves the utilization rate of each user's computer, but also greatly expands the application range of computers, and enables Each user realizes the sharing of computer software and hardware resources and data resources. The long-distance real-time control of computers and the long-distance collection of data can also be carried out by using data communication. [0003] Ethernet (Ethernet) is currently the most common communication protocol standard used in data communication. In an Ethernet network, routers, HUBs, switches, and PCs are connected with net...
