Abstract
An intelligent alarm digital distribution frame comprises a distribution frame body with a transmitting-receiving terminal, wherein an alarm unit is arranged on the distribution frame body, and comprises a sampling and fault analysis circuit and an alarm output circuit, the input end of the sampling and fault analysis circuit is connected with the transmitting-receiving terminal, and the output end of the sampling and fault analysis circuit is connected with the input end of the alarm output circuit. When a transmission level monitored by the sampling and fault analysis circuit is identical with a preset normal value after comparison, namely the difference value is zero, the alarm output circuit does not output alarms, or the alarms are outputted by the alarm output circuit when the transmission level monitored by the sampling and fault analysis circuit is larger than the preset normal value. The intelligent alarm digital distribution frame has the advantages that a tandem double-end device can be intelligently monitored, the fault end can be automatically indicated, the nature of faults can be confirmed, the possibility of fast searching the faults is achieved, the time and labor are saved, and the network management monitoring staff is reduced.
Description
Technical field:
The utility model relates to a kind of transmission junction terminal that uses, specifically a kind of intelligent alarm digital distribution frame in communications.
Background technology:
Digital distribution frame be make digital communication equipment digital code stream connect into as a whole, but speed from the input of the signal of 2Mb/s-155Mb/s, output all terminating on digital distribution frame, for distribution, wire jumper, switching, dilatation are provided convenience.Along with number of users is on the increase, network demand is rapid growth thereupon also, and the digital distribution frame end is difficult in time find as breaking down.Present traditional distributing frame when fault takes place, can only pass through network management monitoring with nowhere to turn to alert and Presentation Function, needs many personnel, many office points per user to investigate in a large number, time-consuming, effort, the direct and indirect loss that has caused country and users.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides and a kind ofly saves time, laborsaving and can find out rapidly the fault end not, the intelligent alarm digital distribution frame of character.
The purpose of this utility model is achieved in that it comprises and has the distribution support body of receiving and dispatching terminal, it is characterized in that: on this distribution support body, be provided with Alarm Unit, this Alarm Unit is made of sampling and accident analysis circuit and alarm output circuit, sampling links to each other with the transmitting-receiving terminal with the input of accident analysis circuit, and sampling links to each other with the input of alarm output circuit with the output of accident analysis circuit.The transmission level that arrives with the accident analysis circuit monitoring when sampling with set normal value when more consistent, when promptly difference be " 0 ", alarm output circuit and export with nowhere to turn to the police; When sampling and accident analysis circuit monitoring to transmission level time alarm output circuit just has alarm output greater than setting normal value.
The utility model has the advantages that and can realize intelligent monitoring the two-end device of tandem, automatically the indication fault end not, determine nature of trouble, for find out rapidly fault provide may, save time, laborsaving, reduce the network management monitoring personnel.
Below in conjunction with accompanying drawing the utility model is done with explanation.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the Alarm Unit zoomed-in view;
Fig. 3 is the utility model circuit block diagram;
Fig. 4 is the utility model circuit theory diagrams.
Embodiment:
By accompanying drawing as can be known, the utility model comprises distribution support body 1 and is located to have on this distribution support body 1 receives and dispatches terminal R1, T1, R2, the Alarm Unit 2 of T2 and alarm indicator LED, this Alarm Unit 2 is provided with sampling and accident analysis circuit and alarm output circuit, wherein sampling is adopted the 89C51 single board computer with the accident analysis circuit, the input P1.3 of this single board computer, the P1.4 pin respectively with transmitting-receiving terminal R1, T1, R2, T2 links to each other, output P0.5, the P0.4 pin respectively with by diode D1, D3, resistance R 1-R5, capacitor C 1, voltage-stabiliser tube D2, triode G1, G2 and by diode D4, D6 resistance R 6-R8, capacitor C 2, voltage-stabiliser tube D5, the switching circuit input that triode G3 constitutes links to each other, two switching circuits constitute the alarm output circuit with the buzzer FQ indicator light LED that is located at its output, and buzzer FQ is located on the distribution support body 1.The transmission level that monitors when single board computer with set normal value when more consistent, promptly difference be that " 0 " (the circuit normal level is 2.1v) represents to be forward voltage between triode G1 base stage and the emitter normally, so conducting.Collector voltage is 0V after the G1 conducting, and forces the base stage of triode G2 and the voltage between the emitter near 0V, and triode G2 is instead ended partially, and collector electrode is not alarmed output.When single board computer monitors difference when being negative value (circuit level is greater than 2.1V), triode G3 base stage and the conducting of emitter positively biased, collector electrode outputting alarm.Failure mode is as follows:
1, makes a start and open circuit: triode G2 outputting alarm (because of G1 ends, G2 or conducting) greater than the 0.7V forward voltage;
2, the short circuit of making a start: the G2 outputting alarm disconnects test cord alarm constant (illustrate with the b end and have nothing to do);
3, receiving end opens circuit: triode G3 outputting alarm (G3 or the conducting greater than the 0.7V forward voltage);
4, receiving end short circuit: triode G3 outputting alarm disconnects test cord alarm constant (illustrating with the b end irrelevant).
Test cord is for connecting the U-shaped connector (not shown) of a R1 of termination receiving end and b end emission terminal T2.
By alarm output (acousto-optic) and the operation of cooperation test cord, can diagnose location of fault, character accurately and rapidly.
Claims (2)
