Abstract
The utility model relates to an anti-theft warning device for an audio cable, which comprises a protected audio cable, wherein the audio cable, a SPC (stored program control) exchange power supply and a relay form a closed loop I; and a normally-opened contact of the relay is arranged in a communication machine room, and the normally-opened contact of the relay, a power supply and an acousto-optic warning device form a closed loop II. In the anti-theft warning device adopting the technical scheme, a voltage relay and a protected cable are utilized to form a loop, and a power supply which is below 48V is provided by a SPC exchange; and when the cable is cut off for the first time, a normally-closed contact is triggered to be closed by the relay due to the loss of voltage actions, an electric bell gives an alarm, and an indicating lamp is lightened to remind an attendant that the cable is cut off. The anti-theft warning device is convenient to realize, the alarm can be given in time, and the audio cable is prevented from being stolen.
Description
Technical field
The utility model relates to a kind of voice-frequency cable burglar alarm, and being particularly useful for communications equipment room has under people's situation on duty the voice communication cable anti-theft alarm of approach remote districts.
Background technology
At present, power supply unit is multi-point and wide-ranging, contain office space, business hall, transformer station, dependents' district etc., some areas message capacity is less, it is higher to transform the optical fiber communication expense, many at present employing voice-frequency cables are realized voice communication, and these places often are located in isogonic distal part position, suburb, and voice-frequency cable is cut easily.
Summary of the invention
The purpose of this utility model finds that in time voice-frequency cable is stolen, reduces the voice-frequency cable burglar alarm of economic loss.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises protected voice-frequency cable, and described voice-frequency cable and programme-controlled exchange power supply, relay constitute the closed-loop path I; The normally opened contact of relay is arranged in the communications equipment room, and described relay normally open contact and power supply, acoustic-optic alarm constitute the closed-loop path II.
Described acoustic-optic alarm is made up of alarm bell that is connected in parallel and pilot lamp.
Adopt the utility model of technique scheme; utilize voltage relay, protected cable to constitute the loop; provide-the 48V power supply by programme-controlled exchange; when cable is cut off for the first time; relay triggers the normally closed contact closure because of losing the voltage action, and electric bell is reported to the police; pilot lamp is bright, thereby reminds operator on duty's cable to be cut off.The utility model is convenient to be realized, can in time report to the police, and prevents that voice-frequency cable from being stolen.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
Embodiment
When voice-frequency cable is stolen, must cut off twice at least, just can steal center section, between cutting off for twice certain hour is arranged, if can when being cut off for the first time, in time find, just can stop cable stolen, avoid bigger loss.
Based on above-mentioned principle, the utility model has adopted following technical scheme, and as shown in Figure 1, it comprises protected voice-frequency cable 1, and protected voice-frequency cable 1 constitutes closed-loop path I 5 with programme-controlled power supply U0, relay K V; The normally opened contact KV-1 of relay is arranged in the communications equipment room, and relay normally open contact KV-1 and power supply U1, acoustic-optic alarm constitute closed-loop path II 6.Above-mentioned acoustic-optic alarm is made up of alarm bell 3 that is connected in parallel and pilot lamp 4.
Need to prove, in the utility model the power supply of closed-loop path I 5 and closed-loop path II 6 all be selected from programme-controlled exchange in the machine room-the 48V power supply, protected voice-frequency cable 1 at the cable far-end with wire jumper 2 loopbacks.
Like this, when cable was cut off, closed-loop path I 5 triggered closed-loop path II 6 closures because of losing the voltage action, and alarm bell 3 is reported to the police, and pilot lamp 4 is bright, thereby reminds operator on duty's cable to be cut off.The utility model effectively utilizes existing resource, only increases voltage relay, alarm bell, pilot lamp and can realize the voice-frequency cable anti-theft alarm function.
