But, at least with regard to present present situation, such signaling equipment is proved to be inefficient, considerable volume in view of distributing frame, fault must escape from into warning, because this people can not keep to whole day such distributing frame with all one's exertions, in he also must stay in the office as much as possible in addition so that can reply various phones and handle other business demand.

An object of the present invention is to overcome this defective.

For this reason; the present invention relates to be used for to be presented at a kind of equipment of the fault in the protection module of telephone distributing frame; each of these modules comprises a kind of fusible or disk; under the effect of the heat that discharges owing to overvoltage arrester is overheated; this fusible disk is by a kind of Mechatronic Systems contained in this module; at least make this overvoltage short out road of discharging, it is characterized in which comprises at least:

A device, this device is by because of described disk fusing the switch closure that is included in this module being locked, this device is used to establish the information about the existence of fault, promptly has at least one fault on the module in the residing orthogonal sets piece installing of this module or " column " at least; And

Data processing equipment is used for detecting periodically one by one all columns so that determine each existence in them or do not have the information of such fault, and so that therefore show at least first column of breaking down number.

By accompanying drawing, by reading the description of the following examples, will understand the present invention more, the present invention is not subjected to the restriction of this embodiment itself, and these accompanying drawings are:

Fig. 1 is a kind of view of simplifying very much of telephone exchange;

Fig. 2 is a kind of circuit diagram that is used to establish at the device of the fault of a column;

Fig. 3 is the block diagram according to a complete set of equipment of the present invention.

Referring now to these figure, and at first with reference to Fig. 1, telephone exchange 1 is the building of a telephone operator, and it comprises:

Telephone distributing frame 2, it is arranged in the big room 3 of the end of the people's who is responsible for maintenance and monitors office;

Unit automatic switch-board 4.

The front surface of distributing frame comprises the terminal box 5 that links to each other with different users' doublet cord 6; the every docking point that links to each other with each doublet cord of each terminal box links to each other with a module; this module is used for protection and stops overvoltage, each protection module to comprise a lightning arrester or " overvoltage arrester " at least at least.

Each terminal box forms the part of " unit " 7, and this unit comprises tens terminal boxes.

About ten of these unit are one group to be stacked on the vertical line 8, are called " column ", so each column 8 has a hundreds of module usually.

These columns 8 are placed on the whole distributing frame length abreast, and distributing frame can reach 30 meters, and is perhaps longer.

Each protection module comprises fusible disk, by structure, under the overheated effect of overvoltage arrester, in case the pressure that fusible disk is subjected to for a long time will melt, causes the contained various electronic switch closes of module in module.

With reference to Fig. 2, mark 9 is represented in these switches, and it is included in the protection module 10, and this module is inserted on the subscribers feeder I/O end of terminal box 5 for example (Fig. 1).

This switch 9 forms the part that fault is observed circuit, and this fault is observed circuit and is shown among Fig. 2, and is related to all protection modules of identical column.

Recall the further state of the fusing of described disk of term " fault " or " having fault " expression protection module, this fusing is to be brought out by the overheated of overvoltage arrester.

In this embodiment, observe circuit supply by the special-purpose D.C power supply (terminal 12,13) of one ± 48V for this, on terminal board 111, the plus end 12 of this D.C power supply joins with the ground of distributing frame here.Certainly, these magnitudes of voltage and polarity are only optional and be to list by way of example here.

When fusible disk melts, switch 9 closures, for this reason, so the electroluminescent diode 11 of module 10 is activated by its current-limiting resistance 14 and through the diode 15,16,17,18,19 that links to each other with power supply terminal 13, and it is directly polarized then.Electroluminescent diode 11 is luminous then, and this makes it to have fault (also with reference to Fig. 1) by display module 10.

Should be noted that in this observation circuit all protection modules 10 of identical column are parallel placements, are represented simplifiedly by wiring 20.

Meanwhile, direct current flows through three diodes 15,16,17 of a part that forms circuit 21, and this circuit is used to be presented on the unit 7 that terminal box 5 forms its parts (Fig. 1) and has one or more faults.

The pressure drop of each conducting diode 15,16,17 is about 0.6V, is about 1.8V at the voltage of 22,23 of the terminals of these three diodes.

In parallel with these three diodes, promptly between terminal 22 and 23, other electroluminescent diode 24 and its current-limiting resistance 25 of series connection with it are housed also.

The have an appointment work threshold sensitivity of 1.3V of this electroluminescent diode 24, and therefore it is also luminous, this just makes it can (Fig. 1) be presented to have a fault in the described unit 7 at least.

Here should be noted that also that all unit observation circuit 21 in the identical column are in parallel placements, schematically illustrate by wiring 26.

Meanwhile, an electric current directly flows through two diode in series 18 and 19, it makes between terminal 27 and 28 voltage that about 1.2V occurs, this voltage may make 29 conductings of NPN triode, and this NPN triode 29 is that common emitter is installed and makes its base stage polarization through shunt resistance 30 and 31.

A parasitic oscillation is set between the polarization terminals 27,28 of the base stage of triode 29 valuably suppresses electric capacity 32.

The collector load of triode 29 is that the coil 33 by the relay that includes two dry contacts 34 and 35 constitutes.

A fly-wheel diode 54 is set between the terminal of coil 33 usually, and the self-induction of coil 33 can not be ignored fully.

Triode 29 is in the saturated fact makes that flowing through electric current in coil 33 also makes two corresponding contacts 34 and 35 closures subsequently.

In electronics signaling unit 37 (Fig. 1 and 2), the closure of the contact 34 between the terminal 13 and 12, the lightning lamp (lighting lamp) 36 on the top that is positioned at above-mentioned column 8 is given in power supply.This lamp signals intuitively to be reported in and occurs one or more faults on this column 8.

Meanwhile, also provide a kind of sound-producing device 38 or buzzer in the same way, this makes becomes possibility for visual signaling 36 increases a kind of sounding signaling.

According to the present invention, the closure of contact 35 will make two terminals 39,40 of terminal board 111 link to each other, and this makes that going up acquired information through doublet cord 41 at microprocessor 42 (with reference to Fig. 3) becomes possibility.

According to Fig. 3, all columns of distributing frame are a shared microprocessor 42 such as column 8 for example, and with reference to Fig. 1, it is installed in the box 43, hangs on the ceiling 44 in distributing frame residing rooms 32.

Box 43 is flat and bears a two-sided indicating device 45, thereby on its every of two big surfaces, show identical information, this box 43 of giving an example also can be placed on the centre in room 3, and the institute in this room a bit can both discern this information like this.

Thereby, when switch 35 closures, when it inquires its corresponding ports, microprocessor 42 by link 41 receive about with above-mentioned electronic unit 37 corresponding described columns 8 on one or the information of multiple faults more appear.

Corresponding link 41a such as microprocessor 42 requests and electronics column fault display unit 37a, all columns of request distributing frame.

In operating process, microprocessor 42 with a kind of mode of the circulation continuous electronic unit 37 that inquiry is relevant with the continuous column of distributing frame 2 constantly one by one, 37a, or the like.

All distribute a number for each column, for example number 1 is to be positioned at the column that shows office's end.If a column comprises the protection module that there is fault at least one, then relevant with this column switch 35 is just closed.

Microprocessor detects the state of these switches 35 one by one, and it is derived enduringly:

The number that has first column of fault, this number shows on the first half 46 of the two-sided indicating device 45 that links to each other with this microprocessor 42 through a link 48;

And the number that has those columns of fault, and on the Lower Half 47 of this two-sided indicating device 45, show.

In addition, be placed on and also demonstrate this identical testing result in the screen 49 on observer's desk simultaneously, for example, this desk is integrated with his office and is linked to each other with microprocessor by service link 50.

Another link 51 links to each other microprocessor 42 valuably with microcomputer 52, wishes that utilizing data processing to manage these faults becomes possibility if this makes.

Also may be provided with one and disperse link 53, it can be a simple telephone wire, so that can manage fault by remote control.

On the two-sided indicating device 45 in being positioned over room 3, also on the desk of maintenance operator, demonstrate the number of first column that has fault and the number that has those columns of fault, help very much the operator to execute the task.

After having changed or having repaired the module of existing fault, two-sided indicating device 45 cuts out, then maintenance operator get back to him office up to next alarm.
