Its principle of work is, telephone line joint A, B is connected with arbitrary telephone wire, diode D10 * 4, four diodes are formed bridge rectifier, because telephone line voltages has the branch of both positive and negative polarity, the user is when wiring, polarity is connect instead easily, whole circuit can not connect cisco unity malfunction on the contrary because of polarity if do not establish rectifier, the setting of bridge rectifier, can be concerned about the positive-negative polarity of circuitry lines joint, telephone line joint A, B inserts telephone wire in any case, bridge rectifier all can be output as reversing same positive-negative polarity, at ordinary times in the telephone wire voltage about 48V, but short-time pulse voltage can reach 100V, the setting of stabilivolt DW1 is in order to stablize the voltage of circuit, resistance R 53 is current-limiting resistances, controllable silicon SCR 2 provides switching voltage by 3 pin of IC 4 in the automaton alarm control circuit 12, in fact this power control circuit mainly is made up of three parts, the one, talked about IC 3 power control circuits with telecommunication circuit 11, the 2nd, for the IC in the dial-up circuit 10 7 provides power control circuit, the 3rd, for the IC6 in the time base circuit 14 provides power supply control.When simulation carry/aerotron Q20 in the on-hook circuit 9 is during because of saturation conduction, voltage in the circuitry lines provides operating voltage through aerotron Q20, resistance R 59, the IC 7 of LED 1 in dial-up circuit 10, the electric current that is provided can reach several milliamperes, when aerotron Q20 ends, the voltage that provides by telephone wire through resistance R 58, stabilivolt DW2, supply with IC 7 in the dial-up circuit 10 minimum keep electric current, under these two kinds of situations, because of the effect of stabilivolt DW2 is arranged, the UDD pin voltage of IC 7 all is no more than 5.6V.The conducting of aerotron Q20 and button AN3 press and the conducting situation of aerotron Q19 the same, three polar arm Q20 by and aerotron Q19 by and button AN3 do not have closed situation too.Monostable circuit is meant that the IC 6 in the time base circuit 14 provides the monostable power supply.The power supply of IC 6 also comes from two kinds of approach, a kind of approach is, as aerotron Q19, when the saturation conduction of Q20 or button AN3 are pressed, because of telephone line joint A, the voltage that B is 2 is by resistance R 82, diode D13, stabilivolt DW3, the UDD end of the IC 6 of controllable silicon SCR 1 in time base circuit 14 provides operating voltage, another kind of approach is, when 3 pin of the IC 4 in the automatic dialing control circuit 12 have high level to produce, trigger the control utmost point of controllable silicon SCR 2, make the moon of controllable silicon SCR 2, the anode conducting, the anode of voltage in the telephone line behind bridge rectifier is through resistance R 53, controllable silicon SCR 2, diode D11, positive pole to capacitor C 58, capacitor C 58 is in process of charging, can make capacitor C 58, the contact place of resistance R 55, produce a positive pulse in short-term, this pulse is extremely important, can make power control circuit produce following several situations, the one, process resistance R 55 provides the base current of short time from aerotron Q21, cause aerotron Q21 conducting at short notice, aerotron Q20 is saturated at short notice, like this, the voltage anode of telephone line after rectification, by aerotron Q21, resistance R 82, diode D13 is added in the anode of controllable silicon SCR 1, force controllable silicon SCR 2 conductings, for the UDD pin of the IC6 in the time base circuit 14 provides power supply.The 2nd, the positive pulse that capacitor C 58 and resistance R are 55 has triggered the control utmost point of controllable silicon SCR 1 through diode D12, resistance R 78, make the silicon control conducting, 14 pin (UDD) of the IC 6 in the time base circuit 14 have obtained working power, the 3rd, the positive pulse that capacitor C 58 and resistance R are 55 provides the base tension of moment to aerotron Q26 through the resistance R 89 in the time base circuit 14, make aerotron Q26 moment saturated, its collecting electrode transfers active potential to, triggered 1 pin in the IC 6 in the time base circuit 14, made its 5 pin output high level; Simultaneously, provide enough base currents by resistance R 55, R83, diode D14, resistance R 84 to aerotron Q24, make three polar arm Q24 saturated, the base stage of aerotron Q23 is pulled to active potential, aerotron Q23 ends, but controllable silicon SCR 1 this moment normal operation still, on the other hand, the high level of 5 pin of IC 6 output makes aerotron Q21, Q20 keep conducting state through resistance R 83, provide base current to aerotron Q21, until 5 pin of IC 6, till the output low level.5 pin of IC 6 are exported temporary stable state high level, by the 76 charging turn on process of the capacitor C in the dial-up circuit 10, make the saturated and conducting of aerotron Q27, be equivalent to click keypad KB redial key " R ", so, IC 7 in the dial-up circuit 10, with exporting of one one of the telephone number that presets from the TONE pin, serve telephone line through resistance R 85, aerotron Q25 after amplifying, forward warning command centre to through telephone office, after IC 6 had experienced a temporary stable state, 5 pin redirects were low level, and aerotron Q21, Q20 end.The 4th,, to this moment, as if circuit entered on hook, but actual conditions are not like this, because aerotron Q19 still is in conducting state, this moment aerotron Q21, Q20 by the conducting that does not influence telephone line, the HK pin in the IC 7 is still kept low level state, this moment, alarm circuit was put through, and traffic control center or taxicar command centre can utilize the receiver, transmitter and the warning command centre that send in words and the PAC circuit 11 to get in touch.Simultaneously the taxi driver's of distant place emergency alarm alarm sound comprises that recording sound all served telephone line, and command centre also can hear driver's alarm sound simultaneously.When 3 pin of the IC 4 in the automaton dialing alarm control circuit stop the output high level, aerotron Q19 loses base current and ends, aerotron Q20, Q21 end already, aerotron Q25 quits work, and causes controllable silicon SCR 1 to be ended because of the interruption of circuit, causes three polar arm Q23 to end, thereby cause aerotron Q26 to lose power supply again and quit work, no longer conducting of controllable silicon SCR 2, whole circuit quits work, and is in standby and keeps state.
Simulation is carried/on-hook circuit 9, belong to prior art, form by aerotron Q20, Q21, button AN3, resistance R 57, R63, its annexation as shown in Figure 3, one end of the base stage of aerotron Q21 and the resistance R of previous stage 55 joins, and the collecting electrode of aerotron Q25 joins in the common point of the end of the collecting electrode of aerotron Q20, button AN3, the emitter of aerotron Q19 and the dial-up circuit 10 of next stage.
Its principle of work is, Fig. 3, A among Fig. 5, in 2 access telephone wires of B, voltage in the telephone wire is about 48V at ordinary times, when aerotron Q21 conducting, for aerotron Q20 provides enough base currents, cause aerotron Q20 saturation conduction, at this moment, voltage on the telephone wire is reduced to about 12V through the dividing potential drop of resistance R 63, aerotron Q19 also plays the same function with aerotron Q20, both conductings all can make circuit produce the microphone that is equivalent to mention in the phone, therefore can be aerotron Q19, the conducting of Q20 is called simulation and carries machine, both differences are that aerotron Q20 is by aerotron Q21 triggering and conducting, and aerotron Q19 is by 3 pin triggering and conducting of the IC 4 of automaton dialing alarm control circuit 12.
