Abstract
The utility model relates to an annunciator used for anti-theft warning, in particular to an opening annunciator of a vehicle. As a mechanical structure is adopted to be interlocked with a delay unit, which means that the delay unit is opened as long as a key is inserted into an electronic switch key, and the delay unit begins timing; if the electronic switch key is not authenticated and opened in a preset time, the delay unit then considers the unlocking behavior to be abnormal unlocking, thereby sending a warning signal to the annunciator; then the annunciator amplifies the sound for warning. The annunciator of the vehicle has diversified functions, and has the capacity of judging whether a vehicle door is normally unlocked or not, thereby being capable of selectively implementing accurate warning.
Description
Technical field
The utility model relates to a kind of antitheft annunciator of warning that is used for, particularly a kind of automobile door opening annunciator.
Background technology
Existingly be used for vehicle-borne alarm against theft, major part is people or the object with the infrared detector detection door outside, in case open this type of detector, as long as the people is arranged near reporting to the police.Obviously, under a lot of situations, this class alarm is judged too simple.Therefore, how judge whether the pilferage behavior is taking place vehicle, and to report to the police be the problem that we need solve in complex situations.For example, the general pilferage occurs in, and has only vehicle to be under the static situation, and is to remove to touch car door, lock with key or picklock that various forgeries are duplicated and so on.
In view of the above problems, the utility model relates to a kind of automobile door opening annunciator.It has technical characterictic as mentioned below, to solve existing problem.
The utility model content
In order to solve the problems of the technologies described above, the utility model provide a kind of simple in structure, fast judge whether the automobile door opening annunciator of reporting to the police.
A kind of automobile door opening annunciator of the present utility model is characterized in that, comprising:
Tachogen, signal amplifier, relay, detector, annunciator;
Described tachogen is connected with described signal amplifier, and described signal venting is connected with described relay, and described relay is connected with described detector, and described detector is connected with described annunciator.
Above-mentioned automobile door opening annunciator is characterized in that, also comprises: with described annunciator bonded assembly delay unit.
Above-mentioned automobile door opening annunciator is characterized in that, also is provided with and described delay unit bonded assembly electronic switch lock.
At first, tachogen is used to judge whether vehicle remains static, if static, begin to send Vehicular status signal, after the signal amplifier processing, be sent to relay, the closed detector that starts of relay switch, detector is an infrared detector, whether probe vehicles has the people in front of the door, if the people is arranged then send a signal to annunciator, is used to activate annunciator but does not report to the police, if the no one does not then activate annunciator.
Owing to adopt the interlock of physical construction and delay unit, as long as be that electronic switch lock has the key insertion promptly to open delay unit, delay unit carries out timing, if in the time of setting, also electronic switch lock is not authenticated and opens, delay unit thinks that then the behavior of unblanking is improper unblanking, thereby send alerting signal to annunciator, the annunciator warning that amplifies.
Description of drawings
Fig. 1 is the structural representation of automobile door opening annunciator.
The specific embodiment
According to claim of the present utility model and the disclosed content of utility model content, embodiment specific as follows is described for the technical solution of the utility model:
Referring to shown in Figure 1, a kind of automobile door opening annunciator of the present utility model is characterized in that, comprising:
Tachogen, signal amplifier, relay, detector, annunciator;
Described tachogen is connected with described signal amplifier, and described signal venting is connected with described relay, and described relay is connected with described detector, and described detector is connected with described annunciator.
Above-mentioned automobile door opening annunciator is characterized in that, also comprises: with described annunciator bonded assembly delay unit.
Above-mentioned automobile door opening annunciator is characterized in that, also is provided with and described delay unit bonded assembly electronic switch lock.
Whether tachogen is used to test wheel and rotates, and promptly is to judge whether vehicle is static, sends Vehicular status signal when rotating speed is zero and handles the back to relay via signal amplifier.
The closed detector that starts of relay switch, detector is a TX982 type microwave detector, whether probe vehicles has the people in front of the door, if the people is arranged then send a signal to annunciator, is used to activate annunciator but does not report to the police, if the no one does not then activate annunciator.
Electronic switch lock is to be chosen in common door lock, and installs micro-switch additional by transforming in lock core, touches micro-switch as long as key inserts lockhole, can activate delay unit.
Delay unit comprises circuit such as 555 o'clock integrated circuit, RC circuit, relay, and relay K control next stage annunciator is arranged.The time of delay unit can be thought setting.Adjusting the value of R or C can make amendment to delay time.
Annunciator comprises the chip of voice series integrated circuit, and inside has comprised audio-frequency power amplifier and electro-acoustic transducing device.
At first, tachogen is used to judge whether vehicle remains static, if static, begin to send Vehicular status signal, after the signal amplifier processing, be sent to relay, the closed detector that starts of relay switch, detector is an infrared detector, whether probe vehicles has the people in front of the door, if the people is arranged then send a signal to annunciator, is used to activate annunciator but does not report to the police, if the no one does not then activate annunciator.
Owing to adopt the interlock of physical construction and delay unit, as long as be that electronic switch lock has the key insertion promptly to open delay unit, delay unit carries out timing, if in the time of setting, also electronic switch lock is not authenticated and opens, delay unit thinks that then the behavior of unblanking is improper unblanking, thereby send alerting signal to annunciator, the annunciator warning that amplifies.The utility model functional diversities has and judges whether car door is the ability of normally unblanking, thereby can optionally carry out accurate warning.
The foregoing description only is giving an example of the optional embodiment of the utility model, and its related feature only is used for explanation and sets forth the technical solution of the utility model, and is not used in qualification protection domain of the present utility model.
