Specific implementation mode

To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below In conjunction with specific implementation mode, the utility model is expanded on further.

As shown in Figures 1 to 8, it is a kind of based on phone control switch remote rebooting device, including crust of the device 2 and Step-down rectifying circuit 3, relay circuit 4, single chip circuit 5 and the safety certification being arranged on 2 internal circuit board of crust of the device Circuit 6, the step-down rectifying circuit 3 and socket 1 are electrically connected, the relay circuit 4 and single chip circuit 5 respectively with drop Voltage rectifier 3 connect, step-down rectifying circuit 3 by with external AC 220 V voltage receptacle 1 be connected as single chip circuit 5 and 4 direct current supply of relay circuit, the single chip circuit 5 is connect with relay circuit 4 and safety certification circuit 6 respectively, described The outside of crust of the device 2 is equipped with interchanger 8 and fixed telephone device 7, and the fixed telephone device 7 connects with safety certification circuit 6 It connects, the interchanger 8 is connect with relay circuit 4.

It is worth noting that, the alternating current that the socket 1 is 220 volts.

In addition, the interchanger 8 is electrically connected with socket 1.

If Fig. 2 is ring detecting circuit, when phone called, telephone exchange sends out ringing signal, and bell signal is The sine wave of (25 ± 3) Hz, voltage effective value about 90V, ring repetition period are 5s, wherein 1s rings, the gaps 4s, due to ring Signal voltage is relatively high, is depressured through Capacitor apart when input and after full-bridge rectification, is input to the input terminal of optocoupler 4N35, to So that optocoupler output is obtained low level signal, the detection of ringing signal and jingle bell are counted to microcontroller.

If Fig. 3 is circuit for answering schematic diagram, the SPC telephone exchange of telecommunication bureau is according to electricity to the response of phone off-hook Words line loop electric current becomes larger, and when interchanger detects that loop current becomes about 30mA, is considered as telephone set off-hook, When user's off-hook (answering the call), the load of about 200 Ω is connected in telephone set by hook switch, entire phone line loop is made to flow through about The electric current of 30mA, interchanger just stops ringing-current transmission after detecting the electric current, and line voltage distribution is become to the direct current of 10V, Complete closing of the circuit work.When microcontroller sends out off hook signal (high level), Q3 transistors conducting, to driving power Pipe Q2 is also switched on, and fictitious load resistance R24 generates the electric current of about 30mA by access telephone wire both ends, to complete simulation off-hook Function；At the end of remote setting operates, on-hook signal (low level) is sent out by microcontroller, to make Q3 and Q2 end, phone Line loop current vanishes, the programme-controlled exchange of telecommunication bureau complete the cut-out work of telephone line.

Such as the DTMF decoding circuit schematic diagrams that Fig. 5 is the utility model, DTMF touch-tone signal decoding circuits are current The widely applied circuit in the equipment such as push-button phone, programme-controlled exchange.DTMF transmitters are used for the dual-audio of telephone key-press number Signal is sent, and realizes voice-frequency dialing.Touch-tone signal is one group to be believed by the combination that high-frequency signal and low frequency signal are formed by stacking Number, the frequency correspondence of the button and touch-tone signal that are used in telephone set generally uses MITEI companies as listed by Fig. 4 Decoding devices of the MT8870 of production as dtmf signal.MT8870 has the function of that circuit is simple, strong, low in energy consumption, the operation is stable The advantages that reliable, when the touch-tone signal sent on telephone wire is sent to the 2nd foot (IN-) of MT8870 through C3 and R25, double-tone Multifrequency pulse first through the dialing tone filter inside MT8870, filters out dial tone signal, then premenstrual to put big rear feeding Dual-audio filter is separated double-audio signal by high and low audio signal, then through high and low pass filter and range detector After make a gift to someone output decoding circuit, after digital operation, its data-out port (the 11st~14 foot) export corresponding two System binary-coded decimal.Data output end D1~D4 of MT8870 is connected to P1.O~P1.3 feet of P1 mouthfuls of microcontroller, and microcontroller is through Pl mouthfuls The corresponding button number of low 4 identification.A, B, C, D key in Fig. 4 is often used as redialing, recording playback, the functions such as hands-free use.It uses It should be noted that the binary system binary-coded decimal of MT8870 outputs is not 0000 for 0 number key when decoding data (D1~D4), but 1010.In addition, the output of * and # keys are respectively 1011 and 1100.When MT8870 obtains effective touch-tone signal and is decoded into After work(, the level of the 15th foot is got higher by low, notice microcontroller can fetch the high level according to, the 15th foot be delayed one section when Between after can be automatically restored to low level.And the voice signal etc. of invalid double-audio signal or telephone line noise, people be will not Cause the data of MT8870 decoded.

If Fig. 6 is microcontroller governor circuit figure, microcontroller has 6 kinds of clocks using the STC89C52 series of macrocrystalline company Operational mode improves 1 times than common single-chip microcomputer speed, and the EEPROM of interior band can be used for the storage and modification of code data.Its Middle Pl.O~P1.3 feet are used for the reading of double-audible frequency device output data；P1.5 feet are used to simulate the control behaviour of off-hook or on-hook Make；P1.7, P3.O, P3.1, P3.3, P3.6, P2.6 foot connect LED indication luminous tube；9th foot connects reset circuit；P3.4 feet The 15th foot of double-audible frequency device is connect, for testing whether there are double-audible frequency data to complete output；P2.O-P2.5 feet are for controlling Button processed；Power switch of the foot of P2.7, P0.5~0.7 for electric appliance controls.

If Fig. 7 is relay drive circuit figure, Switch control is carried out the switch control of AC power using relay, driven Dynamic circuit low-power transistor 9013, the direct current small package relay of relay 5V, parallel diode is used on control coil In elimination inverse peak voltage.

If Fig. 8 is power circuit diagram, power circuit needs to provide two groups of voltages, and SCM system uses 5V power supplys, voice Chip and double-audible frequency chip use 3V power supplys, and circuit of three-terminal voltage-stabilizing integrated LM7805 and LM317, periphery are used in design Circuit is simple, and performance is stablized.

Based on switch remote above-mentioned, that this kind is controlled based on the switch remote rebooting device that phone controls based on phone Step-down rectifying circuit 3 in rebooting device with external AC 220 V voltage receptacle 1 by being connected as single chip circuit 5 and relay 4 direct current supply of device circuit, when staff is dialed with arbitrary communication apparatus and restarts dress based on the switch remote that phone controls When setting the number of fixed telephone device 7 of connection, incoming telephone signal can be sent to the peace in crust of the device 2 by fixed telephone device 7 Full authentication circuit 6 sends electric signal to single chip circuit 5 after the confirmation of safety circuit 6 is errorless, passes through monolithic electromechanics The analysis authentication on road 5 can send the incoming telephone signal to monolithic after safety certification circuit 6 confirms that incoming telephone signal is correct Electromechanical road 5 then needs to continue input execution password, and the execution password of input translates into electric signal and sends microcontroller to again Circuit 5, safety certification circuit 6 can reaffirm whether electric signal password is correct at this time, and certification electric signal is fed back to monolithic Electromechanical road 5 after confirming that electric signal password is errorless, will send out drive by the analysis authentication of single chip circuit 5 to relay circuit 4 Dynamic electric signal, relay circuit 4 will be disconnected first and is closed afterwards, that is, complete the remote reboot of interchanger 8.
