Problems solved by technology

Nowadays, the control mechanism at the front end of the network management system can only observe the operation of the system through the PC. Once it is damaged, the operation of the system cannot be observed, and the existing control mechanism cannot intuitively judge whether the system is receiving or sending data.

Embodiment 1

[0017] like figure 1 Shown, the present invention comprises central processing unit CPU1, central processing unit CPU2, real-time clock chip, LCD display module, indicator light, expansion data input and output port, RAM, EPROM and modem, described central processing unit CPU1, real-time clock, LCD The display module, EPROM and the expansion data input and output ports are all connected to the central processing unit CPU2; the RAM is connected to the central processing unit CPU1 and the central processing unit CPU2; the expansion data input and output ports are also connected to a modem and a buzzer; The above indicators are connected to the expansion data input and output port and the modem at the same time.

[0018] The control terminal includes a communication unit composed of a central processing unit CPU2 and a PC, a central processing unit composed of a central processing unit CPU1, a storage unit, a real-time clock chip, an LCD display module, an indicator light, an ext...

Embodiment 2

[0021] The preferred specific structure of the present embodiment on the basis of Embodiment 1 is as follows: the LCD display module includes an LCD display, an LED input and output data status display and a receiving level display module, wherein the LCD display and the LED input and output data status display are all compatible with Receive level display module connection. The LCD display module provides an observation platform for the system. It can display the current working status of the system, and the input value of the keyboard can also provide an intuitive display for system query. In order to avoid hardware conflict, it needs to provide chip selection signal by the chip selection component. The ED input and output data status display shows whether the system is receiving or sending data. The receiving level display module visually displays the level value of the received signal.

[0022] The central processing unit CPU2 is also connected to the keyboard, and the ...

Abstract

The invention discloses an HFC network management system front end control mechanism allowing data receiving and transmitting to be easily judged. The HFC network management system front end control mechanism comprises a CPU1, a CPU2, a real-time clock chip, an LCD module, an indicator lamp, an extended data input and output port, an RAM, an EPROM and a modulator-demodulator. The CPU1, the real-time clock, the LCD module, the EPROM and the extended data input and output port are connected to the CPU2. The RAM is connected with the CPU1 and the CPU2. The indicator lamp is connected with the extended data input and output port and the modulator-demodulator. Based on the principle, multiple components are arranged and used for displaying and observing the running condition of a system, and the HFC network management system front end control mechanism guarantees that the running condition of the system can be observed at any time, is provided with the indicator lamp used for visually displaying whether the system receives or transmits signals, so that observation is more convenient.

Description

technical field [0001] The invention relates to the field of network management, in particular to a front-end control mechanism of an HFC network management system which is easy to judge data sending and receiving. Background technique [0002] The main purpose of HFC network management system is to control the impact of HFC network uplink channel noise on communication quality, collect and process the data of multiple user terminals, and control each terminal by issuing commands. It can provide the temperature, carrier level, signal level, noise, signal-to-noise ratio and other control and management of the user terminal. In terms of data transmission, according to the network construction, you can choose to transmit data through cable TV lines, telephone lines, or use HFC network and telephone lines to transmit data. At present, with the rapid development of my country's CATV industry, the traditional CATV network is gradually changing into a hybrid fiber-coaxial cable ne...
