Detailed ways

The utility model will be further described in detail below in conjunction with the embodiments and accompanying drawings, but the implementation of the utility model is not limited thereto.

Example 1

Figure 1 is a structural block diagram of a digital repeater indoor coverage system using a mixed network of super five types of lines. The system includes a near-end device and at least one remote device; wherein the near-end device is provided with at least one network port and at least one Optical ports, each remote device has at least two network ports for cascading. After multiple far-end devices are cascaded, they are connected to the near-end devices through Category 5e cables or optical fibers. As shown in Figure 1, several remote devices are cascaded and connected to the near-end device; the near-end device and the remote device form a star structure, and a plurality of remote chain structure.

When the short-distance transmission between the near-end device and the far-end device does not exceed 100 meters, it is preferable to connect the near-end device and the far-end device through a super five-type cable; if it is a long-distance transmission, the near-end The end device preferably transmits the data signal to the remote device through an optical fiber. Since the clock synchronization will gradually deteriorate with the cascaded levels, the number of cascaded remote devices should be controlled within a reasonable range to prevent system stability from being damaged.

Example 2

Fig. 2 is the structural block diagram of the indoor coverage system of the digital repeater station using the super five-category hybrid network, the system includes a near-end device, at least one remote device, and at least one routing relay end; wherein the near-end device is equipped with At least one network port and at least one optical port, each routing relay end includes at least two optical ports or network ports for cascading, at least one network port for connecting remote devices, each remote device is set There is at least one network port for connecting to the routing relay end or the near-end device, and multiple routing relay ends are cascaded to connect to the near-end device. As shown in Figure 2, the routing relay end and the next routing relay end are cascaded and connected to the near-end device, and several remote devices are respectively connected to the routing relay end; the remote device can also be directly connected to the near-end device . It can be seen that in this embodiment, the near-end device and the routing relay end form a star structure, and multiple routing relay ends are cascaded to form a chain structure, thereby forming a mixed network of optical fiber and super five lines way, can achieve the purpose of long-distance transmission.

The function of the routing relay end in this embodiment is to forward the signal and monitoring data packets sent by the near-end device through the optical fiber or super-five lines to each remote device or to the next route when going down. Relay end; when uplink, combine the signals received by each remote device with the monitoring data packet, send it to the near-end device, and forward the data packet sent by the next routing relay end upwards.

Compared with Embodiment 1, this embodiment has more routing relay terminals, which are most suitable for transmission at a distance of 100 meters; for applications that require long-distance transmission, an optical port for long-distance transmission must be added to the remote device. Therefore, Embodiment 1 is suitable for applications with a smaller system, and this embodiment is more suitable for applications with a larger system. However, in this embodiment, there may be a situation where the remote device and the routing relay end access different network ports of the near-end device at the same time, and any access identification technology for the remote device and the routing relay end needs to be considered.

In the networking mode of this embodiment, the near-end device is used as the master station in the monitoring topology, the routing relay end is used as the slave station, and the remote device is used as the slave machine. It is worth considering that the near-end device and the remote device or the routing relay end The communication port between the master station and the slave station must consider the compatibility of the communication between the master station and the slave station, and the communication port between the routing relay terminal and the remote device must consider the compatibility of the slave station and the slave station communication; When accessing the routing relay end or remote device, it can identify whether the routing relay end or the remote device according to the data protocol. If the arbitrary access identification between the remote device and the routing relay is not considered, when some network ports of the local device are directly connected to the remote device, and other network ports are connected to the routing relay, port inequalities will occur. occurs, causing the system to fail to operate normally.

As shown in Figure 3, in order to make the near-end device automatically recognize that the remote device is still the routing relay end, so as to solve the problem of port asymmetry, the slave FPGA of the remote device at the access end or the slave station at the next routing intermediate end can The FPGA transmits a type word to the routing relay end. After the type word is sent to the routing relay end, it is unpacked by the Ethernet unpacking module and is compared with the type of other ports in the relay end FPGA of the routing relay end. Words form a routing table, and the routing table can exist in the routing relay end and the near-end device, and the routing table indicates whether each port of the routing relay end or the near-end device corresponds to the routing relay end or the remote device.

The following only uses the routing relay end to describe, and the near-end device is similar to this. The monitoring system of the routing relay end reads the corresponding register in the relay end FPGA of the routing relay end through the APP program to query the routing table, and can identify whether the corresponding port is the next routing relay end or a remote device. When the monitoring system at the routing relay end sends data packets to the port, by querying the routing table, you can choose to send data packets through the slave interface, slave receive channel and slave send channel, or through the slave station interface, slave station receive channel and slave station The station transmission channel is sent. If the receiving end is a remote device, the monitoring data packet will be read directly by the slave monitoring system after unpacking. If the receiving end is the next routing relay end, the slave of the next routing relay end will The station monitoring system forwards the monitoring data packet to the address corresponding to the remote device or the routing relay end, and the target machine reads it. The relay end monitoring system in the routing relay end forwards the next received routing relay end monitoring data packet to the near-end device through the interface of the main station, the sending channel of the main station and the receiving channel of the main station. The monitoring data packet of the end device is combined with the data packet of the remote device on other ports, and then sent to the near-end device through the interface of the main station, the sending channel of the master station and the receiving channel of the master station, and then the FPGA of the master station of the near-end device unpacks it and then sends it to the near-end device. The monitoring data packet is read by the monitoring system of the master station of the near-end device.
