Operation principle:The call maintenance instrument, when work, L1, L2 are two p-wires:
One, the repair of ringing circuit
When duplex service switch is to S-1, J1 obtains electric actuation, and J1-2 closures (open by the normally closed points of J1-J2-1-duplex repair
Close 1-transformer 80V output ends) exchange 80V voltage D1 rectifications, C1, J1-2, C5, output about 90V voltages produce at the both ends L1, L2
Raw ringing signal is repaired as the ring of phone and is used, and in order to judge the size of ringing level signal in maintenance process, is being tieed up
The other end for repairing switch has sealed in the circuit being made of D4, R3 and gauge outfit to drive gauge outfit to show ringing level signal amplitude, such as
It is connected to phone then phone ring under hook state.Maintenance personal can judge the failure institute of ringing circuit by audio frequency voltmeter
;
Two, the repair of speaking circuit
When duplex opens service switch S-2, the 40V alternating voltages of power transformer output are through D2 halfwave rectifier and C2, R1, C3
L1, L2 both ends direct current 60V are sent by normally closed point J1-1, D3 rectifications of J1, J2 windings after " π " mode filter of composition and are used as phone
DC power supply, L1, L2 two be terminated with telephone set.Lifting Telephone handset, then phone internal resistance seals in circuit, and J2 obtains electric actuation,
J2-2, which is closed, connects music chip power, and music is sent by C4, J1-1, C5, D3, J2 winding to L2, there is graceful sound in receiver
It is happy, illustrate that speaking circuit is working properly.Receiver, which does not have music then to show that speaking circuit is faulty, when maintenance needs to repair.Then it hangs
Machine;
Three, voice-frequency dialing, pulse dialing repair
D5, D6 and C6, C7 constitute multiplication of voltage detecting circuit under pattern when duplex opens service switch S-2, lift tested
After the telephone handle repaiied, there will be corresponding level indicating against receiver blowing gauge outfit, when overhauling voice-frequency dialing, display screen 3
Show dual-tone dialing level, when overhauling pulse dialing, with pulse dialing, J2 sends out the interrupted actuation of coincidence pulse number
Sound, you can the pulse dialing circuit of phone is overhauled with sound, repair circuit plate 15 uses dual-audio post code IC
Seven sections of LED charactrons display driving integrated circuits of MC145436 and decoder CD4511 compositions, when overhauling dual-tone dialing,
Seven segment digital tubes show dialled number, very intuitively;The single chip CMOS double-audio signal (DTMF) of model MC145436
Receiver, it contains filter and decoder, and the double-audio signal that can meet one DTMF standards detected, and convert
At corresponding hexadecimal number switch capacitor filter has been used in the sequential control circuit and output circuit of MC145436
Technology so that the influence very little of power supply noise, and there is band resistance well to act on dialing tone;
Four, transformer exports
The 5V voltages of power transformer output provide power supply for music IC, while being also that charactron LED displays are driven
It is dynamic to provide power supply, and can access the on/off indicating circuit of R3, D9 composition.J2 coil windings flow through D2, D3 half-wave
Direct current after rectification is attracted, and J2-2 is closed, and J1 is released, and the both ends L1, L2 become the 40V DC voltages to be connected by J1-1, together
When music circuit connect, one routing C4 be sent into circuit, maintenance speaking circuit use, another way through D4, R2 be sent into audio frequency voltmeter
Make voice-frequency dialing instruction, R3, D9 are used as used in 5V power supply instructions.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, people in the art
Member can as needed make the present embodiment the modification of not creative contribution after reading this specification, but as long as at this
It is all protected by Patent Law in the right of invention.
