Abstract
The present invention aims at solving the problem of available telecommunication cable failure monitoring method, which is not convenient and fast. The technological scheme is that each cable to be monitored has one pair of idle telephone lines, and the idle lines are connected to the signal input ends of telecommunication line failure range finder, whose signal output ends output signal to computer via interface circuit, city telephone network and modem. The present invention is convenient, accurate and fast and can realize unattended optical terminal machine room.
Description
The present invention relates to telecommunication cable, especially a kind of telecommunication cable failure monitoring method.
Since China's telecommunication system self-operating, network cable takes place because of reasons such as stolen, barbarous construction often cause local communicating interrupt accident.This class accident is also brought many difficulties to circuit repairing and line security protection simultaneously in case appearance will cause great economic loss to country and user.Because the time that accident takes place is often uncertain, there are not distance and anchor point accurately yet, the line maintenance personnel normally declare according to user's fault and judge which row cable is damaged, and will seek the last definite damage section of ability along the line along impaired this row cable, and the public security career personnel think that captured at jobsite pilferage molecule is extremely difficult especially.Existing communication fault stadimeter, as the patent No. is the telephone cable burglar alarm measuring equipment of ZL95219402.3, can only measure line length and alignment numbering between stolen point and the stadimeter, because of line cord is not linearly extended usually, even how accurately used fault localization instrument spacing, the user can not know the actual residing geographic position of stolen point at once, in addition, existing stadimeter can not well adapt to present municipal telecommunication network, stadimeter is in case after reporting to the police, the stadimeter scene must have the people to manage in person, because municipal telecommunication network is huge, wants comprehensively telecommunication network to be realized that monitoring must need great amount of manpower, material resources.
The object of the present invention is to provide a kind of telecommunication cable failure monitoring method of comprehensively, accurately and fast telecommunication cable being realized failure monitoring.
Technical solution of the present invention: in each is monitored the cable of alignment, be equipped with a pair of phone ceases to be busy, the phone ceases to be busy is connected the signal input part of interrogating the line fault stadimeter, and signal interface circuit, telephone wire, the modulator-demodular unit exported from the signal output part of communication fault stadimeter arrive computing machine.
Advantage of the present invention: 1, convenience, user of service of the present invention is the public security officer especially, need not can use this cover surveillance through Special Training.2, accuracy, because the present invention selects computing machine for use, when programming, carried out the consideration of multiple situation for the signal that imports into, therefore, can determine the on-site roughly figure of title and trouble spot in the definite place of fault origination point more exactly, can eliminate effectively and lie about, report by mistake phenomenon.3, rapidity, because scene, front end supervisory system unit of the present invention need not the people, signal enters terminal by municipal telephone network, the staff can launch an attack rapidly behind the acquired information from the related printer of computing machine.4, multichannel, front end supervisory system unit to monitored columns without limits, and is very suitable.5, long-distance is crossed over optical cable, the supervisory system unit is put can be realized crossing over and no worker monitor in the fiber optic room.
Xu Shu embodiment in conjunction with the accompanying drawings.
Fig. 1 is a block diagram of the present invention.
Fig. 2 is azimuth discrimination circuit theory diagrams of the present invention.
During enforcement, the phone ceases to be busy of drawing in all cables that is monitored alignment is pooled cable.Each phone ceases to be busy 1 in the cable is connected the signal input part BB ' of news line fault stadimeter respectively through an azimuth discrimination circuit 2.It is that light emitting diode D, phototriode T constitute that azimuth discrimination circuit 2 is made of photoelectricity multichannel isolator, when not breaking down, have electric current to pass through in the phone ceases to be busy, then diode D is luminous, thereby make phototriode T conducting, azimuth discrimination circuit signal output terminals A has electric signal output.When the cable that is monitored alignment breaks down, then there is not electric current to pass through in its corresponding phone ceases to be busy 1, corresponding diode D is not luminous, and phototriode T disconnects, and the signal output part A of azimuth discrimination circuit does not have electric signal output.
When being monitored the alignment cable and breaking down, corresponding phone ceases to be busy 1 imports disconnection signal into the signal input part BB ' of communication fault stadimeter, the signal output part connection interface circuit of communication fault stadimeter, interface circuit is selected analog-digital conversion ic 74LS245 for use, simultaneously, the signal output part A of azimuth discrimination circuit imports bearing signal into interface circuit, it is the telephone cable burglar alarm measuring equipment of ZL95219402.3 that its communication fault stadimeter is selected the patent No. for use, but needs to remove alarm, display circuit, on-off circuit and the power supply of this equipment.Signal comes out after the computing machine of the Surveillance center of modulator-demodular unit, telephone wire, modulator-demodular unit arrival each supervisory system units shared at a distance from interface circuit.After computing machine is handled signal,, comprise the geographical figure of geographic position name and corresponding trouble spot of trouble spot etc., use for the operator on duty by the printer prints information that is out of order.
In actual use, a cover supervisory system unit can be set in each satellite exchange or fiber optic room, the signal of exporting from each supervisory system unit all passes in the computing machine of Surveillance center by municipal telephone network.
