Real-time detection control system based on HFC network equipment and detection control method thereof

Abstract

The invention provides a real-time detection control system based on HFC network equipment and a detection control method thereof, wherein the real-time detection control system comprises a real-timecontrol detection device, a network management server and a client, wherein the real-time control detection device is used for detecting and controlling the HFC network equipment in real time; the network management server complete control management at an upper layer; the real-time control detection device partially adopts the corresponding detection control method based on DSP and PGA technologies to carry out fully digital signal transmission, and when terminal equipment in an HFC network completes register on the real-time control detection device, the real-time control detection device can process the inquiry of the network management server on the own working state of a front end, can also receive and process orders, i.e. various GET, SET, and the like which are distributed from theupper-layer network management server and remotely control managed equipment. Compared with the traditional technology, the invention well solves the problems of frequency drift and error rate in thewhole detection control process so that the real-time detection control system can be operated in a high-temperature severe environment, and can still ensure the accurate detection control even if a larger noise signal exists in the network.

[0002] The current HFC (Hybrid Fiber Coaxial Network) network management system generally adopts the network architecture of the network management server and terminal equipment, and with the popularization of this technology, the existing HFC network often has a huge capacity, which is built in The devices on the HFC network are scattered and distributed, which makes it difficult for the network management server to manage the devices on the network. In addition, most of the original transmissions on the HFC network are analog signals, and the signals are easily affected during the transmission process. Interference and attenuation, so it is often necessary to rely on a protocol converter as an intermediate transfer station between the equipment terminal and the network management server, and the usual protocol converter can only play the role of data transmission. With the continuous increase of HFC network capacity , the network often needs to set up various network devices of different standards and standards, because the previous protocol converter itself does not have the function of real-time detection of HFC network device terminals, let alone save the real-time status of each network device terminal, once the network The capacity of the equipment is large to a certain extent

Massive data will inevitably be generated. First, the ability of the network to transmit data is limited. Second, it is difficult for the network management server to process massive data in real time.

The current network management system is difficult to manage stably and reliably. More and more HFC network equipment needs to be managed. However, the market lacks an effective detection and control system that meets real-time requirements, and it is still not suitable for large-capacity HFC network equipment. Without a reasonable and effective testing and management method, it can no longer meet the needs of social progress
