Description

Telephone set with automatic alarm language

The utility model relates to a kind of telephone set, and refering in particular to is a kind of language telephone set with automatic warning function.

Continuous development along with domestic and international language set or circuit, the language alarm telephone set is also in continuous generation, but owing to its structural reason, in use bring some problems: cause language to lose as phone circuit outage or telephone exchange user circuit load increases and cause telecommunication department to ban use of, and the multi-functional alarm call that has has automatic answer function, in use causes the alarm signal confusion.

The purpose of this utility model is to overcome the deficiency of prior art and a kind of automatic warning language telephone set simple in structure, easy to use is provided.

The utility model is to adopt following proposal to realize: receive external information by transducer and trigger the bistable state delay circuit, by bistable state delay circuit triggering governor circuit and then by governor circuit control language combiner circuit, signaling circuit, phone hook switch circuit and delay circuit work in 30 seconds, make language combiner circuit dialogue machine send sound, the signaling circuit is to default designated telephone signaling, the hook switch circuit is connected phone automatically, and telephone set is then reported to the police with linguistic form to the appointed place automatically.

Below in conjunction with accompanying drawing the utility model is elaborated:

Accompanying drawing 1 is the utility model electricity functional-block diagram

Accompanying drawing 2,3,4,5 is the utility model electrical schematic diagram:

Referring to accompanying drawing 1, the utility model is by transducer 1, bistable state delay circuit 2, governor circuit 3, language combiner circuit 4, signaling circuit 5, phone hook switch circuit 6, delay circuit 7 constituted in 30 seconds, and the output of described transducer 1 links to each other with the input of bistable state delay circuit 2, and the output of bistable state delay circuit 2 links to each other with the input of governor circuit 3, governor circuit 3 is by relay control language combiner circuit 4, signaling circuit 5, the operating state of phone hook switch circuit 6 and 30 seconds delay circuits 7, the output of language combiner circuit 4 send sound to phone.

Referring to accompanying drawing 2,3,4,5, transducer 1 can be by fire, coal gas in the utility model, heavy patient's first aid, and transducers such as antitheft knob are formed; Bistable state delay circuit 2 is by ic chip, triode BG3, and diode D1, D2, variable resistor W0, relay A always stops knob K and forms; Governor circuit 3 is by relay J, W, Y, relay A(7), (8), A(4), (5) normal opened contact, A(1), (3) normally closed contact forms; 30 seconds delay circuits 7 are by resistance R 12, capacitor C 9, triode BG ₁BG2, relay C, diode D ₃, Y(1), (2) normal opened contact forms; Language combiner circuit 4 is by memory SRAM, processor CPU, microphone MIC, and capacitor C 1-C7, resistance R 1-R8, R11, RF, triode BG4, BG5, push switch K1-K3, recording display led relay J (10) (11) normal opened contact is formed; Phone hook switch circuit 6 is by relay J (1), and (2) normal opened contact is formed; Signaling circuit 5 is by the urgent storage key N1 of phone, N2, and relay J (4), (5), and C(4), (5) normal opened contact, C(1), (2) normally closed contact is formed.

Language in the utility model in the language combiner circuit 4 can be according to the typing in advance of user's needs, when needing typing, only need press the K2 key, record indicator LED is bright, then the warning language of required typing can be sent in the processor CPU by transmitter MIC, deposits in after treatment among the memory SRAM; Urgent storage key N1 in the signaling circuit 5, N2 is stored in two interior telephone numbers of telephone set in advance for the user.

Operation principle of the present utility model is summarized as follows:

After transducer Q receives external information, connect bistable state delay circuit 2, make relay A adhesive, its normal opened contact A(4) (5), A(7) (8) closed normally closed contact A(1) (3) disconnect, connect governor circuit 3, make the relay J adhesive, relay W adhesive self-insurance, at this moment, relay J, the normal opened contact J(1 of W) (2), J(4) (5), J(10) (11), W(4) (5), W(1) (3) closure, connect phone hook switch circuit B, N1 key in the signaling circuit 5 and the K1 key in the language combiner circuit 4, be stored in the automatic signaling of telephone number in the N1 key, because of the K1 key of language circuit 4 by relay normally open contact J(10) (11) connect, so sound-compound-circuit 4 is by triode BG5, C1, dialogue machine P send words, to specifying phone to send the warning language of depositing record in advance, after 42 seconds, bistable state delay circuit 2 makes relay A, J discharges 3 seconds, instant normal opened contact A(4) (5), A(7) (8), J(10) (11), J(1) (2), J(4) (5) disconnect again, relay A normally closed contact A(1) (3) are closed again, make the K1 key of language combiner circuit 4, phone hook switch circuit 6, the N1 key in the signaling circuit 5 disconnects; Because of relay A(1) (3) junction closure, relay Y adhesive, its normal opened contact Y(1) (2) closure, thus 30 seconds delay circuits connected, make relay C adhesive, its normal opened contact C(4) (5) closure, normally closed contact C(1) (2) disconnect, and make the N2 keyed jointing in the signaling circuit 5 logical, because of after bistable state delay circuit 2 makes relay A discharge for 3 seconds, adhesive again, system repeats said process, makes the K1 key of language circuit 4, and phone hook switch circuit 6 all is switched on work, N2 key in the signaling circuit 5, the telephone number of storing begins signaling, and the like, systemic circulation is to the telephone call of appointment, always stop button K up to there being the people to disconnect, system just quits work.

The model of ic chip is NE555 in the utility model, and the model of memory SRAM is 62256, and the model of processor CPU is YYH402.

In sum, the utlity model has simple in structure, dependable performance, the advantage such as easy to use is suitable for the important places such as family, school, office, hospital, factories and miness and uses.
