Abstract
The utility model discloses an anti-lost and anti-theft alarm, which comprises a coding transmitting circuit and a receiving alarm circuit for decoding. The utility model is characterized in that the anti-lost and anti-theft alarm is composed of a cipher emitter which is put together with a portable object and a portable receiving decoding alarm; the cipher emitter is composed of a machine casing and the coding transmitting circuit which is arranged in the machine casing; a switch and an indicator light are arranged on the machine casing; the receiving decoding alarm is composed of the machine casing and the receiving alarm circuit for decoding which is arranged in the machine casing; the switch is arranged on the machine casing. The utility model has the advantage that operation is convenient and portable objects can be prevented from being stolen lost.
Description
The utility model relates to a kind of alarm, specifically its anti-mistake burglar alarm of being made up of two parts that separate.
Alarm is extensively used, and various alarms respectively have its features and applications, but general alarm is to design for antitheft.Do not see have openly for alarm technology that is not only antitheft but also anti-loss at present.
It is a kind of easy to use that the purpose of this utility model is to provide, and can prevent that carry-on object is stolen, can prevent the anti-mistake burglar alarm that carry-on object is lost again.
To achieve these goals, the utility model adopts following technical scheme: a kind of anti-mistake burglar alarm, comprise encoding transmitting circuit and receive the decoding warning circuit, it is characterized in that: it is made up of the password transmitter that is placed in carry-on object and two parts of reception decoding alarm of carrying, the password transmitter is made up of a casing and the encoding transmitting circuit that is located in the casing, casing is provided with a switch and pilot lamp, receive the decoding alarm and be made up of a casing and the reception decoding warning circuit that is located in the casing, casing is provided with a switch.
Good effect of the present utility model is: the password transmitter is placed in carry-on object, receiving the decoding alarm carries, when leaving owner, the object that the password transmitter is housed surpasses the distance of setting, the reception decoding alarm of carrying sends chimes of doom, reaches the anti-antitheft purpose of losing.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is a preferred embodiment password of a utility model transmitter surface structure synoptic diagram;
Fig. 2 is a preferred embodiment encoding transmitting circuit of a utility model schematic diagram;
Fig. 3 is that preferred embodiment of the utility model receives decoding alarm surface structure synoptic diagram;
Fig. 4 is that preferred embodiment of the utility model receives decoding warning circuit schematic diagram;
The utility model is made up of two parts, and the password transmitter 10 of parts for being placed in carry-on object, another parts are the reception decoding alarm of carrying 20.
At first see also Fig. 1, shown in Figure 2, password transmitter 10 is made up of a casing 11 and the encoding transmitting circuit 15,16 that is located in the casing, and casing is provided with a power switch 12 (K1), a pilot lamp 13 and a hanging hole 14.Coding circuit 15 is connected to form through lead by 12 switches (S1 to S12) and 12 universaling coder U1 (its model is PT2262), and its function is to inject prefabricated sign indicating number.Radiating circuit 16 is connected to form through lead by emitting antenna L, coil L1, triode Q1 and resistance, electric capacity, and coding circuit exports transistor base in the radiating circuit to, realizes that the 300M higher-order of oscillation transmits.
See also Fig. 3, shown in Figure 4 again, receive decoding alarm 20 and be made up of a casing 21 and the reception decoding warning circuit 24,25,26 that is located in the casing, casing is provided with a power switch 22 (K2) and a hanging hole 23.Receiving circuit 24 is made up of high frequency receiving circuit and amplification and rectification circuit, high frequency receiving circuit triode Q2 collector output audio signal is to amplification and rectification circuit triode Q3 base stage, this triode Q3 collector exports decoding circuit 25 to, and this decoding circuit 25 is connected to form through lead by 12 switches (S13 to S24) and 12 universal decoder U2 (its model is PT2272).Decoding circuit exports warning circuit 26 to, and warning circuit mainly is made up of four Si Mite phase inverter U3C, U3F, U3E, U3D and loudspeaker Y 1 polyphone, and the model of four Si Mite phase inverters is 4584, and its function is formed memory, vibration promotes to report to the police.
Encoding transmitting circuit that the utility model relates to and reception decoding warning circuit have multiple version, so do not describe in detail.
When the utility model uses, the password transmitter is placed in the carry-on object, connect the power switch on the casing, pilot lamp begins flicker, and expression password transmitter is started working, receiving the decoding alarm carries, connect the power switch on the casing, should send " tick, tick " sound, expression is started working, after receiving the coded transmitter signal, " tick, tick " sound stops.When the object that coded transmitter is housed surpasses setpoint distance as more than 3.5 meters the time from owner, receive the decoding alarm send chimes of doom until two machines distance less than alarm distance.
