Background technology
Article such as personal effects such as handbag, mobile phone are easy to lose owing to do not note.This has brought inconvenience to life.Though a kind of alarm that uses in travelling was once arranged, it is by a transmitter and a receiver, transmitter constantly sends signal, receiver constantly receives the signal of transmitter, when surpassing communication distance owing to variable in distance, receiver does not receive signal can send alerting signal immediately, reaches the purpose of keeping an eye on article.Because this alarm aims at the travelling design, not high on power consumption requires, as long as can work continuously 1 to 2 day, just can reach the properties of product requirement, but powered battery is adopted in long-term work, the consumer just can't accept.Its two, the said goods does not reach one by one corresponding, when a plurality of people use simultaneously, as long as an operate as normal even handbag exceeds distance, can not produce warning yet.Its three, audible alarm can influence its people, especially when wrong report, the noise pollution environment.
Summary of the invention
The purpose of this invention is to provide a kind of interactive alarming device, it also can use for a long time using small-capacity cells particularly during button cell.
A kind of interactive alarming device that second purpose of the present invention provides, its supporting a pair of reception, the use between the dispensing device can not influence third-party use.
The 3rd purpose of the present invention is the influence that reduces when a kind of interactive alarming device that provides is reported to the police environment.
The object of the present invention is achieved like this, designs a kind of interactive alarming device, and it comprises a wireless launcher, and a radio receiver is characterized in that: wireless launcher is used for the wireless signal that timed sending has coding; One radio receiver, it comprises that nothing connects receiving circuit, control circuit, warning circuit, control circuit is used for regularly opening does not have the receiving circuit work that connects, when when opening wireless receiving circuit work, detect the coded message that wireless launcher sends at certain distance, when not receiving coded message or coded message and supporting coding when inconsistent, provide alerting signal by alarm.
Described alerting signal is the vibration signal that Vib. provides.
Described alerting signal is optional information of voice prompt.
Described timed sending and time of reception were 1 to 10 seconds.
Described certain distance is 0.1-3m.
Described wireless launcher is by a high-frequency tube, a switching tube, one timing controller is formed, high-frequency tube and the surperficial device of sound constitute the high frequency power transmitter of shaking, the emitter of high-frequency tube is electrically connected with the collector of switching tube, the emitter of switching tube be electrically connected, base stage is electrically connected with the control end of timing controller.
Described radio receiver comprises antenna circuit, the low noise pre-amplification circuit, mixing inspection frequency circuit, amplify comparator circuit and timing control circuit, antenna circuit is made up of capacitor C 1 and inductance L 1 and antenna, capacitor C 1 and inductance L 1 in parallel the electrical connection, enter low noise pre-amplification circuit input end with antenna contacts after by capacitor C 2, mixing inspection frequency circuit is arranged between low noise pre-amplification circuit and amplification comparator circuit, the output of mixing inspection frequency circuit is electrically connected with the amplification comparator circuit, amplify comparator circuit output and be electrically connected with the control circuit test side, control circuit is connected with warning device by triode.
The output terminal of described LM 358 negative terminals and comparer is electrically connected with the I/O mouth of single-chip microcomputer 2, and an I/O mouth is used to control its work, and another is used to detect coded signal.
When described single-chip microcomputer 2 detects the coded signal that sends less than wireless launcher, need after repeatedly confirming, to drive eccentric motor work.
Described alarm 6 can be a voice sound, and as " article of running you well are seen in attention ", " band is your article well " voice sound has many groups, and output can be selected.
Because wireless launcher of the present invention and radio receiver adopt timed sending and reception, regularly dutycycle can reach more than 500, its electric current is about 4ma when radiating circuit is worked, electric current has only several UA when not working, so average working current has only about 10UA, and the button cell of 100ma also can be worked more than 1 year.And receiving circuit adopts timing working equally.Receiving circuit is reported to the police and is adopted voice or vibration, can not influence its people's life when reporting to the police like this.By encoding one to one, can not report by mistake so on the one hand, but multichannel is worked simultaneously on the other hand, can not influence each other between wireless launcher and the radio receiver.
