Description

Multifunction alarm device

The utility model belongs to a kind of alarm, is to the improvement of existing automatic alarm of beeper and transmission customizing messages device, is applicable to various places such as family, office, Ku Cang, bank.

The present alarm that occurs, kind is more, function is different, have central controlled, also have to work alone, wherein more advanced is the automatic call alerts device of beeper paging system, and this machine is use in parallel with phone, in advance the beeper number is deposited in the alarm, the alarm enabling signal is to control by being arranged on the series connected switches that family's door and window etc. locates, in case improper opening the door (window) situation occurs, switch just disconnects, enabling signal of input alarm, the beeper warning system is worked immediately, and the beeper carrier signal that receives the report for police service very soon uses more convenient, but also there is following shortcoming: 1, the control circuit complexity, the cost height is not easy to generally apply; 2, function singleness has only antitheft effect, and all can not report to the police to situations such as fire, gas concentration exceed standard, and this has just limited the automatic warning function of beeper paging system greatly.

The purpose of this utility model is that development is a kind of when the condition of a fire occurring, when robber feelings or gas concentration exceed standard, can specifying simple in structure, the multiple functional multifunction alarm device of beeper, telephone call from trend.

The utility model multifunction alarm device comprises the coding signaling circuit of being made up of ic chip, keyboard, triode and Resistor-Capacitor Unit; Warning circuit and the power supply formed by power amplifier, warning integrated package and loudspeaker; Coding is by the input end C11-C41 of keyboard through IC, R11-R41 sends into IC and stores, send out number is the coding that will store, send into local telephone by pulse signal through the complex pipe signaling circuit that the DP of IC end, triode Q01, Q04 form, it is characterized in that: adopted the sensitive Multifunction Sensor of infrared ray, coal gas and environment temperature, sent out number control circuit and power supply control switching circuit; Send out number control circuit by triode Q1, Q2 be serially connected in relay J 1, J2 and contact J1-1K thereof on Q1, the Q2 collector respectively, J1-2K, J2-1K forms; On the Q2 base stage, be connected to the delay circuit that R2, C1 form, when sensors A is come noble potential, make Q1 conducting, J1 adhesive, after J1-1K, J2-2K connect local telephone circuit and warning circuit respectively, when certain value is delayed time in the C1 charging, just conducting of Q2, the J2 adhesive, J2-1K connects signaling circuit; The power supply control switching circuit constitutes by resistance R 4, diode D1, relay J 3 and with anodal contact J3-1K, the J3-2K that links to each other of standby power supply E.

The utility model has following advantage than prior art:

The utility model has been owing to adopted Multifunction Sensor to infrared ray, coal gas and thermotonus sensitivity, so but a tractor serves several purposes to the condition of a fire, steal feelings and gas concentration and exceed standard and all can report to the police, has enlarged the usable range of existing beeper paging system; Coding sends out number control circuit and the power supply control switching circuit adopts electronic component and the combined circuit of relay, reasonable in design, circuit is simple, volume is little, cost is low, convenient and practical, promotional value is arranged.

Be described further below in conjunction with drawings and Examples:

Accompanying drawing is circuit theory diagrams of the present utility model.

IC among the figure adopts the UM91265 integrated package, the HK end is the test side of initialize switch K1, DP is for sending out number end, the storage of coding: earlier with initialize switch K1 closure, this moment, the HK end was electronegative potential, beeper or telephone number are by the C11-C41 of keyboard input IC, the R11-R41 end stores in IC, and input finishes, K1 disconnects, and HK is a noble potential.

The transmission of coding: when the robber, sensors A is accepted the infrared signal that human body discharges, output noble potential, triode Q1 conducting, relay J 1 adhesive on its collector, contact J1-1K connects local telephone, is ready, when the C1 of the charging timing circuit that constitutes as R2, C1 is charged to certain value, just conducting of Q2, J2 adhesive simultaneously, contact J2-1K just connects signaling circuit, and the R2C1 delay circuit can avoid J1, J2 adhesive simultaneously to produce misoperation; After J2-1K connects signaling circuit, the complex pipe signaling circuit output that beeper or telephone number are formed through the Pulse Dialing output terminal DP of IC, through triode Q01, Q04, DP end control complex pipe signaling circuit, break-make with control telephone line intermediate ring road electric current, be about to pulse signal and mail to telephone exchange, coded signal is delivered to beeper carrier or predetermined available phone machine by local telephone; Electronic lock B is a power control switch, and during without alarm, electronic lock B cuts off the electricity supply; The VDD of IC is a power supply, provides power supply by local telephone to VDD during sending out number, is powered to IC by this internal power supply during non-number, and R08, C01, D3 form simple mu balanced circuit.

The power supply control switching circuit, by resistance R 4, diode D1, relay J 3 and with the anodal contact J3-1K that links to each other of standby power supply E, J3-2K constitutes, a capacitor C 2 also on J3; During mains failure, J3 discharges, the J3-1K closure, and J3-2K disconnects, and connects standby power supply E, and because of the D1 buffer action, power supply E can not make J3 produce misoperation; After civil power is normal, the J3 adhesive, J3-1K disconnects, the J3-2K closure, mains-supplied, and charge to standby power supply E through R4, D1.

Among the figure, Q1, Q2 triode can be used 3DG12, and C1 is 100 μ F, and L+, L-are telephone line interface, and C is the power amplifier and the integrated package part of warning circuit; When using this alarm, pre-determine alarm temperature, generally will be higher than simultaneously 10 ℃ of room temperatures, the coal gas concentration that exceeds standard is carried out by national regulation, through to the condition of a fire, steal feelings and three sensing sensitivity test determinations of coal gas, it is sensitive reliable, easy to operate to report to the police.
