Description
Technical field
This utility model relates to leaking cable monitoring technical field, particularly relates to a kind of leakage cable monitoring system.
Background technology
Leakage cable is the abbreviation (Leaky Coaxial Cable) of leakage coaxial cable, be referred to as the most again leaky cable or
Leaky cable, its structure is basically identical with common coaxial cable, by inner wire, dielectric with have periodically outside slotted eye
Conductor three part forms.Electromagnetic wave passes through slotted eye outwardly radiated electromagnetic wave, extraneous electricity while longitudinally transmitting in leakage cable
By slotted eye, magnetic field also can sense that Lou cable is internal and is sent to receiving terminal.Leaky cable collection signal transmits, launches and reception etc.
Function, in one, has the dual function of coaxial cable and antenna simultaneously, is particularly well-suited to cover highway, railway tunnel, city
The region that the radio signal propagations such as subway are limited, leaky cable coordinates repeater or repeater simultaneously, is the weak interval of wireless signal
The effective means that signal covers.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of leakage cable monitoring system, with solve of the prior art not
Foot.
In order to achieve the above object, the purpose of this utility model is achieved through the following technical solutions:
One leakage cable monitoring system is provided, for the duty of in real time monitoring leakage cable, near including Surveillance center, repeater
Terminal, repeater, monitoring main frame, two power splitters, monitor up from machine, monitor descending from machine, from machine antenna and load, described prison
Control center, described repeater near-end machine, described repeater and described monitoring main frame are sequentially connected with, and described monitoring main frame is by described
Two power splitters connect by the cable that leaks hunting, described by the other end of the cable that leaks hunting by described monitoring up from machine or described monitoring descending from
Machine connects described from machine antenna or described load, and described monitoring main frame is provided with power-sensing circuit and voltage comparator.
In technique scheme, described repeater is repeater remote termination.
In technique scheme, described Surveillance center is provided with auto-alarming module and autopolling module.
Compared with the prior art, the beneficial effects of the utility model are:
Realize automatic monitor for continuously and fast monitored leakage cable is abnormal, the duty of leakage cable can be exported continuously, letter
Source output is stable, and the transmission impact on signal is preferably minimized.
Accompanying drawing explanation
The accompanying drawing constituting a part of the present utility model is further appreciated by of the present utility model for providing, and this practicality is new
The schematic description and description of type is used for explaining this utility model, is not intended that improper restriction of the present utility model.?
In accompanying drawing:
Fig. 1 shows the structural schematic block diagram of this utility model leakage cable monitoring system.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
It should be noted that in the case of not conflicting, the embodiment in this utility model and the feature in embodiment can
To be mutually combined.
With reference to shown in Fig. 1, this utility model leakage cable monitoring system, for the duty of the cable of monitoring leakage in real time, including prison
Control center 1, repeater near-end machine 2, repeater 3, monitoring main frame 4, two power splitter 5, monitor up from machine 6, monitor descending from machine
7, from machine antenna and load, Surveillance center 1, repeater near-end machine 2, repeater 3 and monitoring main frame 4 are sequentially connected with, and monitor main frame 4
The cable 0 that leaked hunting is connected by two power splitters 5, up from machine 6 or monitor descending from machine 7 by monitoring by the other end of the cable 0 that leaks hunting
Connecting from machine antenna or load, monitoring main frame 4 is provided with power-sensing circuit 41 and voltage comparator 42.
In the technical program, repeater 3 is repeater remote termination, and Surveillance center 1 is provided with auto-alarming module 11 with automatic
Poller module 12.
After obtaining loss inquiry signal, repeater remote termination send a querying command and arrived by RS232 Serial Port Line
Monitoring main frame 4, inquiry data are modulated on the fsk signal of carrier frequency and are sent to monitor through the cable 0 that leaked hunting up by monitoring main frame 4
Descending feeding back from machine from machine 7 from machine 6 or monitor, monitoring main frame 4 receives after machine feedback signal through power-sensing circuit
41 detect incoming level, then compare this incoming level and from the transmitting power number launched from machine by voltage comparator 42
Value is compared, and draws loss value, is shown to Surveillance center 1 by fiber-optic transfer.
From above-described embodiment it can be seen that advantage of the present utility model is:
Realize automatic monitor for continuously and fast monitored leakage cable is abnormal, the duty of leakage cable can be exported continuously, letter
Source output is stable, and the transmission impact on signal is preferably minimized.
Above specific embodiment of the utility model is described in detail, but this utility model has been not restricted to above
The specific embodiment described, it is intended only as example.To those skilled in the art, any equivalent modifications and replacement are the most all
Among category of the present utility model.Therefore, done under without departing from spirit and scope of the present utility model impartial conversion
And amendment, all should contain in the range of this utility model.
