Abstract

The utility model relates to an intelligent alarm for a main distributing frame, comprising a telephone subscriber collecting point of the main distributing frame and a CPU control system. In order to overcome the defect in the prior art that over-voltage and over-current failures occurring on the distributing frame can not be immediately informed to operators on duty, so the operators on duty have to be on duty at site at any time, in the utility model, a failure predication signal acquisition circuit is connected with the CPU control system which is provided with an output terminal sending alarm signals to a public network. The utility model has the advantages of timely and simplified detection, high automatization, simple structure and favorable safety performance.

Description

The main frame intelligent alarm device
The utility model relates to a kind of main frame, particularly a kind of warning device of always joining frame.
Main frame is in the post and telecommunications, a kind of terminals frame that is connected between machine room and the telephone subscriber's (comprising plain old telephone, mobile phone, beep-pager etc.).Its effect except that the telephone subscriber with machine room is connected, also to play the protective effect of overvoltage, overcurrent etc.At present, overvoltage, overcurrent protector action are adopted in overvoltage, the overcurrent protection aspect main frame both at home and abroad usually; Shield to always joining frame to circuit, the equipment of machine room, simultaneously, warning device sends sound, visual alarm, notifies on-the-spot operator on duty that main frame is keeped in repair.When this distributing frame was reported to the police, a certain row (claiming row) that acoustic alarm can only demonstrate distributing frame was broken down, and the maintenance personal need find a certain faulty line in hundred thousands of telephone subscriber lines of this columns, report to the police by light usually and search.The problem that it exists is:
1, need machine room to have the people on duty in 24 hours, one has fault to take place, and must go processing at once, otherwise can be subjected to telephone subscriber's complaint, if untimely processing also can be burnt main frame.
2, present, more and more along with city, town's telephone customer, distributing frame also needs to get more and more, and more and more disperses, and its placement location is by becoming decentralized by cell arrangements in the concentrated of machine room in the past.If it is obviously unrealistic at every place main frame an operator on duty to be set, therefore, can not be in time, accurately, cause the complaint of telephone customer and burning of equipment easilier.So,, press for the unattended problem of main frame that solves at present along with the development of post and telecommunications.
The purpose of this utility model is to design a kind of main frame intelligent alarm device, and it can unattended operation, when distributing frame generation overvoltage, during over current fault, can report to the police automatically, notifies the maintenance personal immediately and informs that fault for information about.
The purpose of this utility model is achieved in that a kind of main frame intelligent alarm device, comprise main frame telephone subscriber collection point and system control cpu, it is characterized in that also having the fault judgement signal acquisition circuit, described fault judgement signal acquisition circuit output links to each other with system control cpu, and system control cpu has the output that sends alarm signal to public network.
The utility model employing fault judgement signal acquisition circuit is at first gathered overvoltage, the over current fault signal on the distributing frame, detects in time and detects and oversimplify; System control cpu is analyzed acquired signal and automatic output port through being connected with public network, reports to the police by public network, and the automaticity height, simple in structure, the safety guarantee performance is good, and is applied widely.
Below in conjunction with accompanying drawing the utility model most preferred embodiment is elaborated:
Fig. 1: the theory diagram of the utility model most preferred embodiment;
Fig. 2: the fault judgement signal acquisition circuit of the utility model most preferred embodiment and cpu system circuit theory diagrams.
As shown in Figure 1, the output of the fault judgement signal acquisition circuit B of main frame intelligent alarm device 1 is connected with system control cpu A, and system control cpu A has the output a that sends alarm signal to public network.The input b of fault judgement signal acquisition circuit B and main frame c circuit are connected, charged online detection (be main frame intelligent alarm device 1 when the charged work of main frame C, be connected charged detection with telephone subscriber collection point c on it).As shown in Figure 2, fault judgement signal acquisition circuit B by input b be optical coupler chip M 1,3,5 or 7 pin respectively on footpath resistance R 1, R2, R3, R4 and the main frame C different telephone subscriber collection point c be connected to form, photoelectricity coupling chip M model is TLP521, and telephone subscriber collection point c can be the telephone subscriber line of row, a module (parts in the row) or a binding post of main frame.The output a that sends alarm signal to public network of system control cpu A connects system control cpu by 1,4 pin of 485 interface circuit communication chip N, and 6,7 pin are that signal sends output and constitutes.
During operate as normal, the online detection main frame of fault judgement signal acquisition circuit B (also can be other any distributing frame); When overvoltage takes place main frame C, during over current fault, the input b of fault judgement signal acquisition circuit B is the input 1 of photoelectrical coupler chip M, 3,5 or 7 pin input overvoltage, over-current signal, be transferred to system control cpu A by output, system control cpu A analysis and judgement, after determining to break down, by output a is 1 of 485 interface circuit communication chip N, the input of 4 pin, signal sends output 6, the output of 7 pin, send alarm signal to public network, notifying the operator on duty in time to show up fixes a breakdown, and can accurately inform fault type, unattended operation is realized in the position; Can help the operator on duty to obtain very easily or write down various required information, make it safeguard distributing frame more accurately and quickly.
