Abstract

The utility model relates to a multifunctional alarm device which not only can implement audible alarm on-site, but also can implement sound automatic alarm by utilizing telephone lines. The utility model is composed of a sensor (1), an alarm and processing system (2), a number input and processing system (3), a power amplifying system (4) and a monitoring system (5). The number input and processing system which can conveniently input telephone numbers comprises a single-chip microcomputer, a software system of the single-chip microcomputer, a number memory, buttons J1 and a J2, a switch K1, etc. The utility model has the advantages of complete function, simple structure, good reliability and low cost, and is suitable for use of theft protection, theft and alarm of financial departments, shops and houses.

Description

Multifunction alarm device

The utility model relate to a kind of not only can on-the-spot audible alarm but also can utilize the telephone line news to ring the multifunctional warning device of reporting to the police automatically, belong to telephone communicating technology field.

In the prior art, the device that utilizes telephone line to report to the police automatically is of a great variety, mostly being single news rings or audible alarm, as " the telephone line autoalarm " of CN2202382Y patent disclosure by trigger element, control module, voice unit and interface unit are formed, interface unit links to each other with the local network subscribers feeder by a normally opened contact, telephone set links to each other with the local network subscribers feeder by a normally closed contact, but telephone number or beeper number are set can only be write input with the calculating machine burning or imported with loaded down with trivial details numeric keypad by manufacturer, use inconvenience, and silent warning function, the circuit structure complexity, element is various, damages easily.

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can be provided with at any time, changes telephone number, multiple functional, simple in structure warning device.

The utility model is made up of sensor 1, warning and disposal system 2, number imput process system 3, power amplification system 4, monitoring system 5, it is characterized in that: sensor 1 taking alarm and disposal system 2; Warning and disposal system 2 also connect number imput process system 3 and power amplification system 4 respectively; Number imput process system 3 also joins with monitoring system 5 and telephone line respectively; Monitoring system 5 is connected telephone wire and power amplification system 4.Warning and disposal system 2 cooperate certain software systems to handle by single-chip microcomputer.Number processing unit 3 comprises that single-chip microcomputer and software systems, number memory and at least two buttons, an element such as switch replace numeric keypad commonly used, finish the input of 0-9 numeral.The single-chip microcomputer that is provided with in the number imput process system 3, the one output terminal is connected single-chip microcomputer with a triode at least with telephone line, and the control alarm outwards dials; Also have an output terminal with a triode single-chip microcomputer and foldback circuit to be connected at least, the feedback or the transmission information of control alerting signal are gone power amplifier, monitoring system.Sensor can be that radar probe or people's body heat are released probe or infrared remote control or temperature sensor etc.This alarm disconnects with telephone wire under the situation of waiting for, and when alerting signal took place, sensor 1 was delivered to signal on warning and the disposal system 2, and promptly trigger control circuit repeat circuit closure is connected alarm and telephone wire.This alarm also is provided with uninterrupted power source, can use as usual during power failure.

The utility model is owing to adopt advanced single-chip microcomputer and memory chip, and simple in structure, volume is little, and performance is strong, good reliability, and cost is low, suitable financial department, shop, the usefulness of dwelling house anti-theft fireproof warning.

Fig. 1 is the utility model functional-block diagram.

Fig. 2 is the utility model one embodiment alarm processing system, number disposal system circuit diagram.

The utility model is described in further detail below in conjunction with drawings and Examples:

Referring to Fig. 1, Fig. 2, the K1 that closes a switch, hummer H sends sound equipment, just can begin to Enter Number.If input digit " 5 ", then with J2 by 5 times, whenever click piezo H and just ring, press 5 times after, press J1 more once, H sends different acoustic, shows that a numeral is imported to finish, so analogize, after the input of all numbers finishes, disconnection K1.Can import tens sets of numbers, long preservation is in number memory IC3 chip.Under the situation of waiting for, this alarm and telephone wire disconnect.When alert news takes place, transducing signal input IC1, trigger control circuit repeat circuit J0 connects alarm and telephone wire immediately; IC1 is transferred to power amplifier unit 4 with signal on the one hand by the software systems of inside simultaneously, sends different alarm sounds and carries out onsite alarming; Give signal of IC2 on the other hand, successively the telephone number of being deposited is sent through triode Q3 by number disposal system 3, the telephone wire feedback signal enters the IC2 judgment processing through universal amplifier A1, if ring-back tone is then waited for, behind the other side's off-hook, IC2 is about to the Q2 switch opens, and monitoring system just can pass field condition to the other side; If busy tone, IC2 is on-hook then, and after waiting several seconds, off-hook, judgement, generating words number are removed up to onsite alarming again.A1, A2 are the general AC amplifier of being made up of LM3241/4, and Q1, Q2 are high countervoltage triode.IC2, IC1 are PIC system single-chip microcomputer, and IC3 is the 24LC series memory.
