In the figures 1, 2 and 3, after the anti-theft door is installed on the anti-theft door and the anti-theft door is closed, the button of the inching type normally closed contact microswitch of the detection circuit 8 is contacted with the door frame of the anti-theft door 3, and the contact inside the inching type normally closed contact microswitch of the detection circuit 8 is in an open state. In the cipher mechanism 11: because when the six power switches of the cipher mechanism 11 are arranged in the plastic shell 2, the three inching type normally open contact power switches and the three inching type normally closed contact power switches are arranged in a cross way according to the requirement, the sequence of the three inching type normally open contact power switches and the three inching type normally closed contact power switches arranged in the plastic shell 2 is not consistent, so each set has different ciphers; because the power input ends of the three inching normally-open contact power switches and the three inching normally-closed contact power switches are connected with the positive electrode of the battery in the mobile phone mainboard 1 through the conducting wire, the power output ends of the three inching normally-open contact power switches and the three inching normally-closed contact power switches are connected with the positive power input end of the second delay circuit 10, and the control power input end of the second delay circuit 10 is connected through the conducting wire, the six power switches of the cipher mechanism 11 have the same appearance, and the buttons of the six power switches are all in an upward state, actually, at the moment, the power output by the battery in the mobile phone mainboard 1 is in a connection state through the power output ends of the three inching normally-closed contact power switches, the positive power input end of the second delay circuit 10 and the control power input end of the second delay circuit 10; the output power of the positive power output end of the second time delay circuit 10 enters the positive power input end of the incoming prompting circuit 3, the first positive power input end of the trigger circuit 4, the positive power input end of the prompting circuit 13 and the positive power input end of the first time delay circuit 9; under the action of the first time delay circuit 9, after 20 seconds, the detection circuit 8 is in a power-on standby state, so that the false alarm of the detection circuit 8 is prevented when a user opens the password mechanism 11 to enable the detection circuit 8 to be in a fortification state and open a security door to go out; when the owner returns home, opens the security door, after the detection circuit 8 gives an alarm, the battery in the mobile phone mainboard 1 needs to be closed, the battery is input to the positive power input end of the second delay circuit 10 through the password mechanism 11, the power of the power input end is controlled by the second delay circuit 10, the three inching type normally closed contact power switch buttons of the password mechanism 11 are pressed, and therefore the power output by the battery in the mobile phone mainboard 1 does not enter the positive power input end of the second delay circuit 10 and the power input end is controlled by the second delay circuit 10; if a thief enters a house, after the detection circuit 8 is electrified to alarm, the thief does not know the password of the password mechanism 11, that is to say, does not know which buttons of the six power switches of the password mechanism 11 should be pressed down, as long as one button of the three inching type normally closed contact power switch buttons of the password mechanism 11 is not pressed down, that is to say, when the internal contacts of one inching type normally closed contact power switch are in the on state, as long as one button of the three inching type normally open contact power switch buttons of the password mechanism 11 is pressed down, that is to say, when the internal contacts of one inching type normally open contact power switch are in the on state, the anode power input end of the second delay circuit 10, the control power input end of the second delay circuit 10 and the power input end of the subsequent detection circuit 8 are all in the electrified state, and the detection circuit 8 can continue to be electrified to alarm.
In fig. 1, 2 and 3, in each use, if the owner needs to go out of the home, the owner needs to press down three jog type normally closed contact power switch buttons of the password mechanism 11 to temporarily turn off the battery in the mobile phone motherboard 1 and input the battery to the positive power input end of the second delay circuit 10 through the password mechanism 11, and the power of the power input end is controlled by the second delay circuit 10, so as to prevent false alarm of the detection circuit 8 when the door is opened, and then the six jog type normally closed contact power switch buttons of the password mechanism 11 are turned on upwards again, so that the battery in the mobile phone motherboard 1 is input to the positive power input end of the second delay circuit 10 through the password mechanism 11, and the power input end is controlled by the second delay circuit 10, and then the output power of the positive power output end of the second delay circuit 10 enters the positive power input end of the mobile phone motherboard 1, the positive power input end of the visitor prompt circuit 3, the first positive power input end of the trigger circuit 4, the positive power input end of the prompt circuit 13, and the positive power input end of the first delay circuit 9; under the effect of first delay circuit 9, after interval 20 seconds, detection circuit 8 can be in the standby state that gets electricity, has prevented that owner from opening 11 password mechanism and making detection circuit 8 set up defences, open the burglary-resisting door when going out, and detection circuit 8 false alarm. After the positive power supply output end of the second time delay circuit 10 outputs power supply to enter the positive power supply input end of the incoming prompt circuit 3 and the first positive power supply input end of the trigger circuit 4, when a guest presses a power supply switch of the incoming prompt circuit 3, a loudspeaker of the incoming prompt circuit 3 sends out 30 seconds of music to remind a host of visiting the guest, and the host opens the door to welcome the guest; meanwhile, the power output end of the visitor prompting circuit 3 charges the second positive power input end of the trigger circuit 4, after 30 seconds, when no one is at home to open the door, the loudspeaker of the visitor prompting circuit 3 does not sound, and then the visitor presses the power switch of the visitor prompting circuit 3 again, the loudspeaker of the visitor prompting circuit 3 sends out happy music again, and at the same time, after 15 seconds, the trigger circuit 4 outputs positive power to enter the positive power input end of the starting circuit 5, so that the starting circuit 5 is powered on to work, and then the starting circuit 5 enables the mobile phone mainboard 1 to be in a starting state. After the mobile phone mainboard 1 is started, the control circuit 6 enables the loudspeaker of the visitor prompting circuit 3 to stop making sound, and after the mobile phone mainboard 1 is started for 20 seconds, the dialing circuit 7 is powered on to work; after the dialing circuit 7 is powered on to work, the dialing circuit 7 can dial a host telephone number prestored under the key of the number key 1 in the mobile phone mainboard 1, at the moment, a visitor can communicate with the host through the mobile phone mainboard 1, and the host and the visitor can respectively master the movement of each other. After the dialing circuit 7 dials for 90 seconds, under the action of the second delay circuit 10, the mobile phone mainboard 1, the visitor prompting circuit 3, the trigger circuit 4, the starting circuit 5, the control circuit 6, the dialing circuit 7, the detection circuit 8, the first delay circuit 9, the prompting circuit 13 and the second delay circuit 10 are all returned to the initial state to prepare for next visitor use, only the visitor prompting circuit 3 and the first delay circuit 9 are in a static standby state, and all the rest circuits and the mobile phone mainboard 1 lose power, so that the defects that the rest circuits and the mobile phone mainboard 1 are powered on all the time to cause overlarge power consumption and inconvenient charging is caused to a user frequently. The front part of the plastic shell 2 is provided with a hole 2-4 from top to bottom and the lower end of the middle part of the back of the plastic shell 2 is provided with a hole 2-8, so that the sound emitted by the loudspeaker of the visitor prompt circuit 3 can be heard by the personnel outside the security door and in the room. When no person is at home, a thief opens the security door 3 to enter the home through an illegal means, and at the moment when the security door leaves the door frame, when the touch type normally closed contact microswitch front end button of the detection circuit 8 leaves the door frame, the start circuit 5 enables the mobile phone mainboard 1 to start through the actions of other related circuits of the detection circuit 8, then the dialing circuit 7 dials through the phone beside the owner, if the owner cannot speak a echo after receiving the phone, the owner represents an express visitor at home, and at the moment, the owner can arrive at home as soon as possible or inform a police and a material pipe to arrive at the site in time, catch the thief, and reduce the loss of the owner; after the owner returns home, the power supply for outputting the battery in the mobile phone mainboard 1 to a subsequent circuit is turned off through the password mechanism 11, and false alarm after the owner enters home can be prevented. In the cue circuit 13: before the alarm clock mechanism is used, the mobile phone mainboard is set to work after 24 hours through the alarm clock function of the mobile phone mainboard 1, and after the anti-theft door is closed, when the buttons of six power switches of the password mechanism 11 are all upward, namely the positive electrode of a power supply output by a battery of the mobile phone mainboard 1 enters the positive electrode power supply input end of the mobile phone mainboard 1, the alarm clock of the mobile phone mainboard 1 enters a timing state; when the timing of the mobile phone mainboard 1 reaches 24 hours, the alarm clock function of the mobile phone mainboard 1 can enable one light-emitting diode on the keyboard of the mobile phone mainboard 1 to emit light, under the action of an internal circuit of the prompting circuit 13, an audio output end of the prompting circuit 13 can output an audio signal to enter a loudspeaker of the visitor prompting circuit 3, so that the loudspeaker always sends out ' the possibility that the old at home may have an accident and please inform a hostage management pipe in time ' of a distress sound ', and after a property patrol worker outside the antitheft door or a neighbor passing through a corridor hears the distress sound, the old at home, a police and the hostage management pipe can be informed to the old at home to apply a rescue hand to the old in time; in practical use, when the old man normally opens the security door once a day, because before the security door is opened to prevent false alarm of the security door opening detection circuit 8, the power supply of the battery in the mobile phone motherboard 1, which is input to the positive power input end of the second delay circuit 10 through the password mechanism 11, and the power supply of the power input end controlled by the second delay circuit 10, needs to be temporarily closed, after the relevant power switch of the password mechanism is correctly operated, the battery in the mobile phone motherboard 1 is no longer input to the positive power input end of the second delay circuit 10, the power input end controlled by the second delay circuit 10, and the power input end of the mobile phone motherboard 1 through the password mechanism 11, the power input end of the mobile phone motherboard 1 is in a power-off state, and under the self function of the mobile phone motherboard 1, the alarm clock of the mobile phone motherboard 1 stops timing; when the old man operates the button of the power switch related to the password mechanism 11, and the button is in an upward state, the positive pole of the battery in the mobile phone mainboard 1 is input to the positive power input end of the second delay circuit 10 through the password mechanism 11, the power input end is controlled by the second delay circuit 10 and the power input end of the mobile phone mainboard 1, the power input end of the mobile phone mainboard 1 is in a power-on state again, under the self function of the mobile phone mainboard 1, the alarm clock of the mobile phone mainboard 1 restarts to count for the next 24 hours, namely, after the anti-theft door is opened every time, the alarm clock of the mobile phone mainboard 1 counts for 24 hours again, and the alarm clock works after the next 24 hours are counted; therefore, if the solitary old people normally open the door once in 24 hours, the prompting circuit 13 can not output the audio signal to inform the property patrol personnel or the neighbors passing through the corridor, and if the door is not opened after 24 hours, the prompting circuit 13 can output the audio signal to inform the property patrol personnel or the neighbors passing through the corridor to rescue, so that accidents caused by the accidental nobody rescue of the solitary old people are prevented; in practical use, if the timing alarm function of the prompt circuit 13 is not needed (for example, a child does not need the function when at home, and a user needs to go out of a door for a long time and does not need the function when no person is at home), the power switch of the prompt circuit 13 is turned off, so that the power output by the battery of the mobile phone mainboard 1 cannot enter the power input end of the prompt circuit 13, and the prompt circuit 13 cannot work even when the alarm clock of the mobile phone mainboard 1 times for 24 hours; if the prompting circuit 13 is turned on, after 24 hours, the prompting circuit 13 enables a loudspeaker of the visitor prompting circuit 3 to sound, and when the old people living alone at home are in a normal state, the old people turn off a power switch of the prompting circuit 13. In practical use, after the power-on circuit 5 works, the signal output from the anode of the light-emitting diode on the keyboard of the mobile phone mainboard 1 to the signal input end of the prompting circuit 13 is automatically cut off, so that visitors are prevented from visiting, the dialing circuit 7 works when the power is on, and the prompting circuit 13 works by mistake when the light-emitting diode on the keyboard of the mobile phone mainboard 1 lights when the mobile phone mainboard 1 dials. The invention enriches the functions of a common doorbell, not only has the functions of prompting visitors and automatically communicating the visitors with a host in a remote way, but also has the anti-theft function and the capability of monitoring the safety of the elderly living alone at home; under the normal use condition, only need half a year to charge once, prevented often to charge the inconvenience that brings for the user. In practical use, after the movable cover 4 is installed, the screw heads of the four screws can be damaged by using a tool, so that the situation that after a thief enters a house, the four screws are detached by using a screwdriver in a short time, and further, related circuits in the plastic shell are damaged, and the plastic shell cannot be normally used is avoided.

Fig. 4, in the dialing circuit and the mobile phone motherboard A4: after the dialing circuit is powered on to work, a direct current power supply output by a battery G in a mobile phone mainboard A4 charges an electrolytic capacitor C5 through a resistor R9, when the dialing circuit starts, a pin 2 of a time-base integrated circuit A5 is at a low potential, the time-base integrated circuit A5 sets a pin 3 thereof to output a high level under the action of a peripheral element resistor R7 and a silicon switch diode VD5 thereof, after 15 seconds, the upper end potential of the electrolytic capacitor C5 (the potential of a pin 6 of the instant base integrated circuit A5) rises to two thirds of a power supply voltage value, the time-base integrated circuit A5 is reset, the pin 3 stops outputting the high level and outputs a low level, the output low level enters an anode power supply input end of a relay K6 through PNP triode VT6 power amplification and phase inversion, and then the relay K6 is powered on to pull the power supply input end and a normally open contact end to be closed; then, the direct current power supply output by the battery G in the mobile phone mainboard A4 charges the electrolytic capacitor C6 from the closed control power supply input end and the normally open contact end of the relay K6 through the resistor R11, when the charging is started, the pin 2 of the time base integrated circuit A6 is at a low potential, the pin 3 of the time base integrated circuit A6 is set under the action of the peripheral element resistor R10 and the silicon switch diode VD6 thereof to output a high level, the output high level enters the negative power supply input end of the relay K7 through the NPN triode VT7 through power amplification and phase inversion, then, the relay K7 is electrified to attract the control power supply input end and the normally open contact end thereof to be closed, after 2 seconds, the upper end potential of the electrolytic capacitor C6 (the pin 6 potential of the instant base integrated circuit A6) is increased to two thirds of the power supply voltage value, the time base integrated circuit A6 is reset, the pin 3 of the relay A6 stops outputting the high level, and then, the relay K7 is electrified to stop attracting the control power supply input end and the normally open contact end thereof; because two power contacts under the number key 1 of the mobile phone mainboard A4 are respectively connected with the control power input end and the normally open contact end of the relay K7 through leads, the relay K7 is electrified to close the control power input end and the normally open contact end within 2 seconds, and under the action of the dialing function of the single key of the mobile phone mainboard A4, the mobile phone mainboard A4 can dial the phone number of a host pre-stored on the number key 1 of the number key of the mobile phone mainboard A4, so that visitors can communicate with the host within one-half minute to master the movement of each other; because the sound that its inside speaker was sent is surreptitious when mobile phone motherboard A4 that adopts worked, and the visitor suggestion circuit's speaker B no longer sounded this moment, and the visitor is apart from the burglary-resisting door closely, so, the visitor can be clear hear the sound that owner sent through mobile phone motherboard A4 speaker when mobile phone motherboard A4 talks. In the second delay circuit: when a relay K1 of the trigger circuit is electrified to attract a control power input end and a normally open contact end of the trigger circuit to be closed and a starting circuit is electrified to work, a power supply output by a battery G in a mobile phone mainboard A4 can charge an electrolytic capacitor C8 through a resistor R14, after about 157 seconds of charging, when the voltage of two ends of the electrolytic capacitor C8 reaches a power supply voltage value, a Darlington tube composed of NPN triodes VT9 and VT10 is sequentially conducted, and low level output by collectors VT9 and VT10 enters a negative power input end of the relay K10, so that the relay K10 is electrified to attract a control power input end and a normally closed contact end of the relay K10 to be disconnected, and as the positive power input end of the mobile phone mainboard A4, a visitor prompting circuit positive power input end, a first positive power input end of the trigger circuit, the first delay circuit positive power input end and the normally closed contact end are connected through a lead, the relay K10 is electrified to attract the control power input end and the normally closed end to be disconnected, and the negative power input end of the mobile phone mainboard A4, the visitor prompting circuit positive power input end, the visitor positive power input end, the triggering circuit positive power input end, the normally closed end and the normally closed end of the first delay circuit can stop working; the power supply output by the battery G in the mobile phone mainboard A4 does not charge the electrolytic capacitor C8 any more through the resistor R14, the voltage charged on the electrolytic capacitor C8 can continuously maintain the conduction of the NPN triodes VT9 and VT10, the relay K10 is continuously electrified and attracted, and after about 10 seconds, when the voltage charged on the electrolytic capacitor C8 can not continuously maintain the conduction of the NPN triodes VT9 and VT10, the relay K10 loses power and stops attracting the control power supply input end thereof and is communicated with the normally closed contact end, so that the mobile phone mainboard A4 positive power supply input end, the visitor prompt circuit positive power supply input end, the trigger circuit first positive power supply input end and the first delay circuit positive power supply input end are in the electrified state again, and the next visitor presses the doorbell to inform the owner or make preparations for communication through the mobile phone mainboard A4. Through the effect of the second delay circuit, the mobile phone mainboard A4, the incoming prompting circuit, the trigger circuit, the starting circuit, the control circuit, the dialing circuit, the detection circuit, the prompting circuit, the first delay circuit and the second delay circuit are all returned to the initial state, preparation is made for next incoming use, only the incoming prompting circuit, the first delay circuit are in a static standby state, and all the other circuits and the mobile phone mainboard A4 are powered off, so that the defects that the power consumption is too large and inconvenience is brought to a user due to the fact that all the other circuits and the mobile phone mainboard A4 are powered on all the time when the mobile phone is frequently charged are avoided. In the detection circuit: when the mobile phone is in use, after a power supply output by a battery G in a mobile phone mainboard A4 enters a power supply input end of the detection circuit through the password mechanism and the first delay circuit, the detection circuit is in a standby state; when the anti-theft door is closed at ordinary times, a button of the inching type normally closed contact microswitch SK is in contact with the left side of the anti-theft door frame, an internal contact of the inching type normally closed contact microswitch SK is in a disconnected state, and the one-way silicon controlled rectifier VS2 is not triggered; when a thief opens the anti-theft door, the inching type normally closed contact microswitch SK button and the left side of the anti-theft door frame are separated by a certain distance, so that two contacts in the inching type normally closed contact microswitch SK are connected, a power supply output by a battery G in a mobile phone mainboard A4 triggers a control electrode of a one-way silicon controlled rectifier VS2 through a resistor R16, the one-way silicon controlled rectifier VS2 is triggered and connected, and then a relay K8 is electrified to pull in a control power supply input end and a normally open contact end of the relay to be closed; because the normally open contact end of the relay K8 is connected with the positive power input end of the starting circuit through a wire, the starting circuit can start the mobile phone mainboard A4, then, under the action of the control circuit and the dialing circuit, the mobile phone mainboard A4 can dial the owner telephone number pre-stored in the number key 1 of the number key of the mobile phone mainboard A4, the owner can communicate with the mobile phone mainboard A4 through a nearby telephone without response and represent a dead person at home, and the owner can catch or scare away a thief by timely returning to home and informing a police or a material pipe, so that property loss is reduced to the lowest limit; after a relay K8 of the detection circuit controls the power input end and the normally open contact end to be communicated, the power-on circuit is powered on to work, the second delay circuit is powered on to work, under the action of the second delay circuit, the dialing circuit enables a mobile phone mainboard A4 to dial to inform an owner of 1 minute and a half of the alarm, and then the mobile phone mainboard A4, the visitor coming prompt circuit, the trigger circuit, the power-on circuit, the control circuit, the dialing circuit, the detection circuit, the prompt circuit, the first delay circuit and the second delay circuit return to the initial state; after the owner returns home, the power supply which outputs the password mechanism to the second delay circuit is disconnected, when the detection circuit is fortified again, the owner turns on the power switches S1, S2 and S4 of the password mechanism, and then the detection circuit is in a fortification state under the action of the first delay circuit.
Fig. 4, the cue circuit: when a visitor presses the power switch SB of the visitor prompting circuit again, the starting circuit is powered on to work, or a thief opens the security door and the owner returns home to open the security door, after the starting circuit is powered on to work, the mobile phone mainboard A4 is powered on and then dials through the dialing circuit to inform the owner, a relay K13 of the starting circuit can be powered on to attract the control power input end and the normally closed contact end of the relay to be disconnected, therefore, the positive power supply of the light emitting diode VL2 on the keyboard of the mobile phone mainboard A4 cannot enter one end of the resistor R17 through the silicon rectifier diode VD7, and the one-way silicon controlled rectifier VS3 is not triggered; before the alarm clock is used, the alarm clock of the mobile phone works after the mobile phone mainboard A4 is set to be 24 hours through the alarm clock function of the mobile phone mainboard A4; after the anti-theft door is closed, when the buttons of the six power switches of the password mechanism are all upward, namely the positive electrode of the power output by the battery of the mobile phone mainboard A4 enters the positive electrode power input end of the mobile phone mainboard A4, the alarm clock of the mobile phone mainboard A4 enters a timing state; when the timing of the mobile phone mainboard A4 reaches 24 hours, the alarm clock of the mobile phone mainboard A4 sounds, namely, the mobile phone loudspeaker sounds, meanwhile, the light emitting diode VL2 on the keyboard of the mobile phone mainboard A4 can be powered to emit light, the power output by the anode of the light emitting diode VL2 is rectified by the silicon rectifier diode VD7 and then triggers the one-way silicon controlled rectifier VS3 to be conducted by the resistor R17, then the relay K12 is powered to attract the control power input end and the normally open contact end to be closed, because the anode power input end of the solid recording integrated circuit A7 is input by the normally open contact end of the relay K12, at the moment, the solid recording integrated circuit A7 can work as an electric worker, audio signals are output from the two ends of the loudspeaker B of the visitor prompting circuit from the 2 feet and the 3 feet of the electric worker, the loudspeaker B always sends out' the accident possibly happens in the home, the help sound of informing the host pipe in time, and after the help sound of the patrolmen outside the security gate or neighbors passing through the corridor, the old can be informed to hear the family, and the old can timely apply the help to the hands. In practical use, when the old man normally opens the security door once a day, because the power supply input to the positive power input end of the second delay circuit and the control power input end of the second delay circuit needs to be temporarily turned off in order to prevent false alarm of the detection circuit for opening the security door, after the relevant power switch of the password mechanism is operated correctly, the power supply output by the battery G in the mobile phone mainboard A4 is not input to the positive power input end of the second delay circuit, the control power input end of the second delay circuit and the power input end of the mobile phone mainboard A4 through the password mechanism any more, under the self-function of the mobile phone mainboard A4, the mobile phone mainboard A4 restarts the next 24-hour timing, that is, after each time of opening the security door, the alarm clock timing time of the mobile phone mainboard A4 is reset and is reset, and the alarm clock can work after the next 24-hour timing arrives; therefore, if the solitary old people normally open the door once in 24 hours, the prompting circuit can not output the audio signal to inform the property patrol personnel or the neighbors passing through the corridor to rescue, and if the doors are not opened after 24 hours, the prompting circuit can output the audio signal to inform the property patrol personnel or the neighbors passing through the corridor to rescue, so that accidents caused by the nobody rescue of the solitary old people are prevented; in actual use, if the timing alarm function of the prompting circuit is not needed, the power switch SK of the prompting circuit is turned off, so that a power supply output by a battery G of the mobile phone mainboard A4 cannot enter the prompting circuit, and the prompting circuit cannot work even after the 24-hour timing time of the alarm clock of the mobile phone mainboard A4 is up; if the prompting circuit is turned on, after 24 hours, the prompting circuit enables a loudspeaker B of the incoming prompting circuit to sound, and when the old people living alone at home are in a normal state, the old people turn off a power switch SK of the prompting circuit. In practical use, after the power-on circuit works each time, the relay K13 can disconnect the anode of the light-emitting diode VL2 on the keyboard of the mobile phone mainboard and the anode of the silicon rectifier diode VD7 of the prompting circuit, so that a visitor is prevented from visiting, the dialing circuit works when the power is on, and the prompting circuit works mistakenly after the light-emitting diode VL2 on the keyboard of the mobile phone mainboard A4 emits light when the mobile phone mainboard A4 dials. When the alarm clock is used for the first time, after a prompting circuit works when power is supplied, namely the set time of the alarm clock is up, a user needs to record a required language into a solid recording integrated circuit A7 (the time of the alarm clock is set to be before the alarm clock is set to be ready for recording for the first time, the alarm clock is powered to work after several minutes, the time of the alarm clock is set to work after sound is recorded), before recording, an upper cover of a plastic shell is opened, the user presses down a jog power switch SD with hands to open the jog power switch SD, then the mouth of the jog power switch is aligned to a loudspeaker B of the guest prompting circuit to record a voice, the voice is 'possible accidents of the old at home, and the old at home can inform a pipe in time', then, an audio signal is stored into the solid recording integrated circuit A7, and the jog power switch SD is closed after the audio signal is recorded into the solid recording integrated circuit A7; when the inching switch SD is turned on for recording, the light emitting diode VL1 emits light, so as to prompt a user that the solid recording integrated circuit A7 is recording. In practical use, when the battery G in the mobile phone motherboard A4 needs to be charged without electricity, the battery G in the mobile phone motherboard A4 can be charged only by plugging a mobile phone charger plug matched with the mobile phone motherboard A4 into the power socket XZ, and only one half-year charging is needed in general use. Through the above, when the invention is used, after a visitor presses the power switch SB of the visitor prompting circuit, the loudspeaker B of the visitor prompting circuit can give out a melody sound to prompt the owner to visit; when no one opens the door at home, the visitor presses the power switch SB again, and under the action of the trigger circuit, the starting circuit, the control circuit and the dialing circuit, the mobile phone mainboard A4 enables the visitor to communicate with the owner automatically and master the movement of the visitor and the owner; when a thief enters a house and wants to steal, under the action of the detection circuit, the starting circuit, the control circuit and the dialing circuit, the mobile phone mainboard A4 can dial the phone around the owner to inform the owner that the thief enters the house, and the countermeasure is taken in time to reduce the loss; when the old people at home do not open the door for 24 hours, the prompting circuit can make the B sound of the passenger prompting circuit inform corridor passing people to pay attention, the old people at home are likely to have accidents, and the old people are timely informed of family members or a material pipe to take rescue measures. The invention only consumes 6mA of electric energy in one day when in static standby state, and only needs to be charged once in half a year when in use, thereby preventing inconvenience brought to users by frequent charging. It should be noted that the present invention is not limited to the above-mentioned embodiments, and any modification, equivalent replacement, or improvement made within the scope of the present invention should be included in the protection scope of the present invention.
