Exchange device, described monitoring device includes local side monitoring collection, remote monitoring collection and connects both monitoring interfaces, described
Monitoring interface and alarm equipment are connected to master control cpu, and described circuit switching equipment connects user interface and master control cpu.
Further improvement as technique scheme:
Described circuit switching equipment is relay, and during power down, relay is in normally off.
Described alarm equipment is buzzer or alarm or alarm lamp.
Described user interface is in series with the first resistance.
By using technique scheme, circuit one is set and 2 two Channel Synchronous of circuit receive and transmit data,
During arbitrary line failure power down, it is possible to allow unspoiled circuit continue no-delay working on free of discontinuities；Monitoring is set
Protection system, the data received according to circuit, the signal being used for monitoring local side and far-end in real time receives situation, is determining this
When any one party does not access signal in ground end or far-end, feed back to monitoring interface the most in time, effectively play bidirectional protective
Effect, monitoring interface selects output " 0 " signal or " 1 " or composite signal to master control cpu, master control cpu according to feedback result
The duty of the output control alarm equipment according to monitoring interface feedback, so that staff passes through alarm equipment with regard to energy
Enough convenient and swift signals knowing local side and far-end accurately receive situation, thus allow staff understand line work state
Good maintenance in time；Arrange circuit switching equipment master control cpu obtain signal receive situation feedback after, control circuit switching equipment
Quickly selecting to access from circuit one or circuit two, master control cpu automatic control circuit switches, it is not necessary to artificially switch, from
And reach undamaged protection E1 circuit.
Accompanying drawing explanation
Fig. 1 is the structure chart one of this utility model E1 line non-loss protector embodiment；
Fig. 2 is the structure chart two of this utility model E1 line non-loss protector embodiment；
Fig. 3 is the structure chart three of this utility model E1 line non-loss protector embodiment.
Detailed description of the invention
Referring to figs. 1 through Fig. 2, this utility model E1 line non-loss protector embodiment is described further.
A kind of E1 line non-loss protector, as in figure 2 it is shown, include master control cpu, transmitting terminal, user interface and transmission line
Road, described transmission line includes circuit one and the circuit two being connected to master control cpu, and described circuit one is additionally coupled to user and connects
Mouthful, described master control cpu is also associated with monitor protective system, and described monitor protective system includes for monitoring local side and far-end letter
Number receive state monitoring device, according to signal receive status alert alarm equipment and according to network on off operating mode switch line
The circuit switching equipment on road, described monitoring device includes local side monitoring collection, remote monitoring collection and connects both prisons
Control interface, described monitoring interface and alarm equipment are connected to master control cpu, described circuit switching equipment connection user interface and master
Control cpu.
By using technique scheme, circuit one is set and 2 two Channel Synchronous of circuit receive and transmit data,
During arbitrary line failure power down, it is possible to automatically switch to circuit one and continue no-delay working on free of discontinuities；Prison is set
Control protection system is used for the signal of monitoring local side and far-end in real time and receives situation, in collecting local side or far-end arbitrarily
When one side does not access signal, feeding back to monitoring interface the most in time, effectively play bidirectional protective effect, monitoring interface is according to anti-
Feedback result selects the knot that output " 0 " signal or " 1 " or composite signal are fed back according to monitoring interface to master control cpu, master control cpu
Fruit controls the duty of alarm equipment, so that staff just can conveniently know this locality by alarm equipment
The signal of end and far-end receives situation, thus line work state is well overhauled in time to allow staff understand；Circuit switching is set
Equipment, after master control cpu obtains the feedback that signal receives situation, controls circuit switching equipment quickly from circuit one or circuit
Selecting in two to access, master control cpu automatic control circuit switches, it is not necessary to artificially switches, thus reaches undamaged protection E1 line
Road.
Preferably, described circuit switching equipment is having a double meaning relay, the normally closed joint connecting wire road one of this relay, power down
Time relay be in normally off.Described alarm equipment is buzzer or alarm or alarm lamp.Lead to when circuit breaks down
Cross visual manner or audible means to remind staff to arouse attention.
It is illustrated in figure 1 the E1 line transmission flow process of simplification, wherein Data Stream Processing, framer framing and transmission data
End is all current prior art；Feature of the present utility model is workflow mode as shown in Figure 3, the portion that dotted line is framed
It is divided into master control cpu, circuit one and circuit two simultaneous transmission of signals, and by the feedback of status of circuit one and circuit two to master control cpu,
The most any one line channel in reception side, user interface place is received.
In order to allow the judgement signal that staff can be simple and clear receive state, all arrange specially for circuit one and circuit two
Local alarm equipment and remote alarm equipment.
Circuit one, the local side of circuit two and far-end are defeated under normal circumstances all has signal to receive, then is sent to monitoring and connects
Mouth is all " 0 " signal, and owing to all alarm equipments need two alarm code, all alarm equipments of circuit one and circuit two are not
Work；
When circuit one this locality does not has signal to receive, complete " 1 " signal of monitoring interface output, circuit one local alarm, master control
Cpu controls the work of corresponding alarm equipment；
There is a signal circuit one this locality, but far-end without receiving time, monitoring interface output " 0 " and the alternating signal of " 1 ", circuit
One remote alarm, so that master control cpu sends " 0 " and the alternating signal of " 1 " to alarm equipment, corresponding alarm equipment flashes
Work；
When circuit two this locality does not has signal to receive, complete " 1 " signal of monitoring interface output, circuit two local alarm, master control
Cpu controls the work of corresponding alarm equipment；
There is a signal circuit two this locality, but far-end without receiving time, monitoring interface output " 0 " and the alternating signal of " 1 ", circuit
Two remote alarms, so that master control cpu sends " 0 " and the alternating signal of " 1 " to alarm equipment, corresponding alarm equipment flashes
Work.
In order to protect user interface, connect the first resistance R preferably to described user interface.It is 75 that this resistance R can match
Europe or 120 Europe.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, without departing from the some improvement under this utility model principle premise and
