Technical field

The utility model relates to a kind of electronic warning equipment, is specifically related to a kind of distance perspective and answers alarm.

Background technology

Along with constant development of economy, the thing that people need handle is more and more, and whether these problems that in life, take place through regular meeting can let you feel to perplex very much: the computer package of tidying up morning, briefcase, and when going out, but forget and take away; Be added to morning evening, on bus, subway, mends morning when feeling, the people that encapsulates at one's side spirits away and carries away; Go out together with friend and to have a meal, smoothly bag is placed on the behind of oneself, the back of having a meal finds that the bag of oneself disappears; Make an appointment with what a client's interview with great difficulty, met with the client and just found because the documentation that the more hasty result that gos out is contained in the bag drops on office; When going on business, at the bus stop, when wait in the railway station, we are at oneself luggage on the stretch constantly, now a distance perspective of needs answer alarm be used to solve more than all puzzlements.

Summary of the invention

The purpose of the utility model is to the problems referred to above, provides a kind of article lost and the distance perspective that can report to the police automatically of can in the scope of setting, can preventing to answer alarm.

Technology that the utility model adopted is as follows: distance perspective answers alarm to answer main frame 14 and remote-control handle 15 to form by distance perspective,

Distance perspective answers main frame to be made up of an ADF7021 Transmit Receive Unit 1, a MC9S08QG8 chip controls unit 2, first led display unit 5, first input block 6, first power supply unit 3 and the first Charge Management unit 4; The one ADF7021 Transmit Receive Unit is connected with a MC9S08QG8 chip controls unit electric signal; The one MC9S08QG8 chip controls unit is connected with the first power supply unit electric signal; First power supply unit is connected with the first Charge Management unit electric signal; First led display unit is connected with a MC9S08QG8 chip controls unit electric signal, and first input block is connected with a MC9S08QG8 chip controls unit electric signal;

Remote-control handle is made up of the 2nd ADF7021 Transmit Receive Unit 7, the 2nd MC9S08QG8 chip controls unit 9, second led display unit 11, second input block 12, loudspeaker alarm unit 8, second source unit 10 and the second Charge Management unit 13; The 2nd ADF7021 Transmit Receive Unit is connected with the 2nd MC9S08QG8 chip controls unit electric signal; The 2nd MC9S08QG8 chip controls unit is connected with second source unit electric signal; The second source unit is connected with the second Charge Management unit electric signal; Second led display unit is connected with the 2nd MC9S08QG8 chip controls unit electric signal, and the loudspeaker alarm unit is connected with the 2nd MC9S08QG8 chip controls unit electric signal; Second input block is connected with the 2nd MC9S08QG8 chip controls unit electric signal;

The one ADF7021 Transmit Receive Unit is connected with the frequency range electric signal of the 2nd ADF7021 Transmit Receive Unit at 433.92MHz.

The utlity model has simple in structurely, volume is little, the advantage of the thing that makes things convenient for the user to seek to shift one's position easily.

Embodiment

Further specify according to Figure of description:

Distance perspective answers alarm to answer main frame 14 and remote-control handle 15 to form by distance perspective, and distance perspective answers main frame to be made up of an ADF7021 Transmit Receive Unit 1, a MC9S08QG8 chip controls unit 2, first led display unit 5, first input block 6, first power supply unit 3 and the first Charge Management unit 4; The one ADF7021 Transmit Receive Unit is connected with a MC9S08QG8 chip controls unit electric signal; The one MC9S08QG8 chip controls unit is connected with the first power supply unit electric signal; First power supply unit is connected with the first Charge Management unit electric signal; First led display unit is connected with a MC9S08QG8 chip controls unit electric signal, and first input block is connected with a MC9S08QG8 chip controls unit electric signal; Remote-control handle is made up of the 2nd ADF7021 Transmit Receive Unit 7, the 2nd MC9S08QG8 chip controls unit 9, second led display unit 11, second input block 12, loudspeaker alarm unit 8, second source unit 10 and the second Charge Management unit 13; The 2nd ADF7021 Transmit Receive Unit is connected with the 2nd MC9S08QG8 chip controls unit electric signal; The 2nd MC9S08QG8 chip controls unit is connected with second source unit electric signal; The second source unit is connected with the second Charge Management unit electric signal; Second led display unit is connected with the 2nd MC9S08QG8 chip controls unit electric signal, and the loudspeaker alarm unit is connected with the 2nd MC9S08QG8 chip controls unit electric signal; Second input block is connected with the 2nd MC9S08QG8 chip controls unit electric signal; The one ADF7021 Transmit Receive Unit is connected with the frequency range electric signal of the 2nd ADF7021 Transmit Receive Unit at 433.92MHz.Distance perspective answers main frame and remote-control handle to use the rechargeable battery power supply.

System starts working; Remote-control handle sends induced signal; Main frame receives induced signal and judges distance between the two, if the detected distance of main frame surpasses set distance, then can transmit an alarm command to handle; Hummer in the handle will send chimes of doom, reminds the position of owner's main frame and the distance between handle to surpass setting value.Distance perspective answers the distance of alarm equipment alarm to regulate.When not using, the power supply that toggle switch just can parting system.

After distance perspective answered the toggle switch of main frame and remote-control handle to be in the open site, system started working, remote-control handle intermittent (frequency be per second several times) send induced signal, include address code information in the induced signal.Distance perspective answers main frame to receive effectively (discernible address code) induced signal, and its inner RF receiving and transmission module detects, judges the intensity of induced signal, and with the signal intensity of setpoint distance to recently determining whether to satisfy the condition of sending alerting signal.If the intensity of the induced signal that receives is less than the signal intensity of setpoint distance, then distance perspective answers main frame to send alerting signal, if the intensity of the induced signal that receives greater than the signal intensity of setpoint distance, then distance perspective answers main frame not make a response.The acquiescence alarm distance of setting is 5 meters (promptly surpassing 5 meters will report to the police), can adjust alarm distance through toggle switch, because wireless signal can receive the influence of factors such as human body, so actual alarm distance has some change.
