Description

The utility model relates to telemechanics, in particular, to systems of telealarm systems (TS) and can be used for remote monitoring and control of telecommunication equipment of broadband access networks.

Known TS systems contain a command and receiving device, as well as communication channels for transmitting TS commands, the command device containing a parameter sensor and a first transceiver, and the receiving device - a second transceiver and information display device (RU 2059293, 04/27/96, G 08 C 19 /12).

However, this system does not provide support for the SNMP (Simple Network Management Protocol) protocol adopted in international management systems.

The technical result of the utility model is to increase the functionality of the system through the use of SNMP protocol and FSK (Frequency Shifted Keying) modulation for reliable messaging.

The management system includes:

- N command devices (transponders embedded in telecommunication equipment (optical nodes, trunk and sub-bus amplifiers, etc.)). Transponders are used for remote monitoring and control of telecommunication equipment parameters (temperature, current consumption, current

pre-stage, terminal stage current, input optical power, output signal level, remote supply voltage, etc.);

- data transmission network based on fiber optic and distribution cable networks of broadband access;

- the head station (GS) as part of the receiving device of the management system, personal computer of the IBM series and information display device, designed as part of the management system for interrogating and collecting information from N command devices.

Thus, it is possible to remotely control (control and adjust) N command devices, knowing the location of each of them (the topology of network equipment placement), and using each i-th transponder to control K sensors (temperature, current consumption, pre-cascade current, terminal current cascade, input optical power, output signal level, remote supply voltage, etc.) and manage the parameters of individual blocks of telecommunication equipment.

The headend, as a rule, is installed in separate rooms and connected via an appropriate interface to a data transmission network (hybrid optical-coaxial networks), as well as through an RS-232 port to a personal computer with software that provides visual control over the quality of equipment operation (Fig. .1,4).

This goal is achieved in that in a system containing a command and receiving device, as well as communication channels for transmitting tele-signaling commands, the command device comprising a parameter sensor and a first transceiver, and the receiving device - a second transceiver and an information display device are additionally introduced into the command device K parameter sensors, a multiplexer, the inputs of which are connected to the outputs of the parameter sensors K, a single-crystal microcomputer, the first input of which is connected to the output of the multip lexor, RS-232 junction, the input of which is connected to the Note Book output, and the output - with the second input of the microcomputer, the associated address and data bus with random access memory, read-only memory, digital-to-analog converter, and an additional output port, a tonal frequency receiver whose output connected to the third input of the microcomputer, an inductor call detector, the output of which is connected to the fourth input of the microcomputer, the first block of electronic keys, the input of which is connected to the first output of the additional output port of the microcomputer, and the output is with control elements of telecommunication equipment blocks, the second block of electronic keys, the first input of which is connected to the second output of the additional output port of the microcomputer, and the first output is with the inputs of the inductor call detector and the receiver of tonal frequencies, the matching node output analog signals with hybrid optical coaxial

a network, the first input of which is connected to the third output of the additional output port of the microcomputer, and the output - with the first output of the second block of electronic keys, a low-pass filter, the input of which is connected to the output of the digital-to-analog converter, and the output - with the second input of the matching node of the output analog signals with a hybrid optical-coaxial network, a duplex transceiver, the first input / output of which is connected to the second input / output of the second block of electronic keys, and the output is loaded onto the communication channel of the hybrid optical-coaxial second network connected with the receiving device headend computer having an input connected to the output of the receiving device, and output - with the display unit.

Comparison with the prototype shows that the inventive device is characterized by the presence of new units and their connections between them. Thus, the claimed device meets the criterion of "novelty."

Comparison of the proposed solution with other technical solutions shows that the listed elements used in the blocks are known, however, their introduction in this connection with the other elements leads to the solution of a new task of environmental monitoring. This confirms the conformity of the technical solution to the criterion of "significant differences".

Figure 1 shows the general block diagram of the proposed management system, where on each i-th equipment III (total N) of a hybrid optical-coaxial network II a transponder is installed, which is connected to K sensors (temperature, current consumption, pre-cascade current, current terminal stage, input optical power, output signal level, remote supply voltage, etc.) and L control devices (ingress control, etc.), and its output is loaded on a hybrid optical-coaxial network II to transmit information to the head station I.

Moreover, each transponder (Fig. 2) contains: a multiplexer 1, a single-crystal microcomputer 3, a logic signal to RS-232 interface signal converter (2), an inductor call detector 8, a tone frequency successor 9, a ROM for storing speech and tone signals 4, promptly -memory storage device (RAM) 5, digital-to-analog converter 6, additional microcomputer output port 7, low-pass filter (LPF) 10, matching node for output analog signals with a hybrid optical-coaxial network 11, electronic key block 12, 14, duplex receiving front transceiver 13.

The management system works as follows.

The system has two algorithms:

1. Programming transponders.

2. Monitoring the parameters of telecommunication equipment.

The first operation algorithm allows you to:

A. Programming Spaced Transponders Using Headend I.

B. Programming transponders using portable Note Book.

Programming is carried out remotely via an optical-coaxial network from the headend or directly by connecting the Note Book to the transponder. Moreover, management teams include:

- Assignment of the transponder identification number (from 1 to N);

- blocking of individual transponder sensors (from 1 to K);

- recording the logical response levels (0 or 1) of individual transponder sensors (from 1 to K), (for example, a decrease in optical power below the permissible level, excess of the permissible temperature, etc.);

B. Setting transponder operating modes: removal or setting into control and parameter control mode.

Parameter control mode.

In this mode, upon request from the headend, transponders interrogate the status of the telecommunication equipment sensors and transmit the received information to the receiving device of the headend management system I. If sensors programmed to the logical level of operation are triggered, the transponder independently transmits information on the malfunction of other equipment of a hybrid optical-coaxial network. At the same time, a specific section of the optical-coaxial network and controlled equipment parameters appear on the display device, where the permissible norms are exceeded.

It is also connected to the input port of the microcomputer 3 and is a linear amplifier and an analog comparator. With it, the microcomputer receives information transmitted over the optical-coaxial network II.

RAM 5 is connected to the system bus and is a standard LSI INTEL 6264 family with a capacity of 8 kbytes.
