Abstract
The utility model belongs to the field of automotive electronic technology, and particularly relates to a dome lamp with a pyroelectric infrared sensor. The dome lamp with the pyroelectric infrared sensor comprises a dome lamp body, wherein the pyroelectric infrared sensor capable of converting infrared signals of human motion into electric signals and sending out the electric signals is arranged inside the dome lamp body, and the pyroelectric infrared sensor is connected with a control unit capable of receiving and processing the electric signals sent out by the pyroelectric infrared sensor and sending the electric signals to a vehicle controller. According to the dome lamp with the pyroelectric infrared sensor, the pyroelectric infrared sensor and the control unit are added to a traditional dome lamp; when an unauthorized person enters a vehicle, an alarming signal is generated to give an alarm, and therefore proceeding of an act of theft is effectively prevented. The dome lamp with the pyroelectric infrared sensor is simple in structure, safe, reliable, and convenient to implement. The anti-theft method of the vehicle is mainly used for preventing articles and parts in the vehicle from being stolen.
Description
Technical field
The utility model belongs to technical field of automotive electronics, is specifically related to a kind of ceiling light with pyroelectric infrared sensor.
Background technology
At present the vehicle anti-theft technology is mainly based on the engine anti-theft technology, and when not detecting the actv. electron key and exist, vehicle can not start, and the antitheft mode of this kind mainly is to prevent that vehicle is stolen.And existing ceiling light illumination equipment in the automobile, inside only comprises the basic structures such as power supply, bulb, switch, its function only is illumination.How the illumination equipment in the car and Vehicle Anti-Theft System are connected and prevent article in the car, part is stolen is present problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists in order to solve the above-mentioned background technology, and a kind of prevent article, the stolen ceiling light with pyroelectric infrared sensor of part in the car are provided.
The technical solution adopted in the utility model is: a kind of ceiling light with pyroelectric infrared sensor, comprise ceiling light, described ceiling light inside is provided with the pyroelectric infrared sensor that the infrared signal of human motion can be converted to electric signal and send electric signal, and described pyroelectric infrared sensor connects can receive the electric signal that pyroelectric infrared sensor sends and the control unit of this signal being processed and is sent to entire car controller.
Further, be provided with the optical system that the infrared ray of human body radiation can be focused in the rpyroelectric infrared detection unit in the described pyroelectric infrared sensor.
Further, described optical system is Fresnel Lenses.Optical system can focus on the infrared ray of human body radiation rpyroelectric infrared and survey in the unit, also produces simultaneously the highly sensitive district of infrared radiation and the blind area that alternately changes, the characteristic that constantly changes to adapt to pyroelectric infrared sensor requirement signal.
Further, described control unit comprise be connected with pyroelectric infrared sensor and with the electric signal of pyroelectric infrared sensor output amplify, amplifying circuit and the filter circuit of filtering, and to electric signal postpone, the signal processing circuit of comparison process and electric signal output is sent to the interface circuit of entire car controller.
Further, described interface circuit sends to entire car controller with electric signal with level signal or bus signals mode.Entire car controller drives warning performance element (such as loudspeaker, remote server) and realizes reporting to the police.
The ceiling light of the utility model band pyroelectric infrared sensor has increased pyroelectric infrared sensor and control unit in traditional ceiling light inside.After unwarranted people enters into vehicle interior, can the human body signal in the car be detected, then generate alerting signal.Alerting signal sends other control units in the car (such as entire car controller etc.) to level signal or bus signals mode, control unit drives warning performance element (such as loudspeaker, remote server) and realizes reporting to the police, and can effectively frighten proceeding of resistance larceny.
The utility model pyroelectric infrared sensor places ceiling light inner integrated with ceiling light, and good concealment is not conflicted with the existing styling design of vehicle; Pyroelectric infrared sensor is with low cost, can effectively control the cost of novel ceiling light.Simple in structure, safe and reliable, it is convenient to implement, and this vehicle anti-theft mode mainly is to prevent that article in the car, part are stolen.
Description of drawings
Fig. 1 is principle schematic of the present utility model.
The specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments, be convenient to be well understood to the utility model, but they do not consist of restriction to the present invention.
As shown in Figure 1, the utility model comprises ceiling light 1, and described ceiling light 1 inside is provided with pyroelectric infrared sensor 3 and control unit 5, and described pyroelectric infrared sensor 3 is connected with control unit 5.
Be provided with optical system 2 in the described pyroelectric infrared sensor 3, optical system 2 is Fresnel Lenses, the infrared ray of human body radiation can be focused on rpyroelectric infrared surveys in the unit, also produce simultaneously the highly sensitive district of infrared radiation and the blind area that alternately changes, the characteristic that constantly changes to adapt to pyroelectric infrared sensor requirement signal.
Pyroelectric infrared sensor 3 is the core devices in the utility model, and it can be converted to electric signal 4 to the motion infrared signal of human body and use for control unit 5.
Described control unit 5 comprises and is connected amplifying circuit and filter circuit and signal processing circuit and interface circuit with pyroelectric infrared sensor.The faint electric signal 4 that signal filtering and amplifying circuit are exported pyroelectric infrared sensor 3 amplifies, filtering is processed; Signal processing circuit is carried out delay, the comparison process of electric signal and is exported to interface circuit.
Described interface circuit sends to entire car controller with electric signal with level signal or bus signals mode.Entire car controller drives warning performance element (such as loudspeaker, remote server) and realizes reporting to the police.
The utility model realizes preventing that article, the stolen principle of part are in the car: by increasing pyroelectric infrared sensor 3 and control unit 5 in traditional ceiling light 1 inside, after the people of when existing (namely do not detect the actv. electron key) enters into vehicle interior without permission, the utility model can detect the human body signal in the car, then generates alerting signal.Alerting signal sends entire car controller 7 in the car to level signal or bus signals 6 modes, and entire car controller drives warning performance element (such as loudspeaker, remote server) and realizes reporting to the police, and can effectively frighten proceeding of resistance larceny.
The content that is not described in detail in this specification sheets belongs to the known prior art of this area professional and technical personnel.
