Description of drawings
Fig. 1 is the structural representation of the utility model embodiment
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, this detection automobile key warning of not pulling out comprises key 1, anti-theft controller 4, vehicle door status detecting device 6 and the warning device 5 that has theftproof chip.Key 1 can be inserted in the key 2 of automobile ignition switch, and anti-theft controller 4 is provided with anti-theft antenna 3, and when key 1 was positioned at key 2, anti-theft antenna 3 can carry out communication by the low frequency radio frequency mode with the theftproof chip on the key 1.Vehicle door status detecting device 6 is connected with anti-theft controller 4, is used to detect the open and close state of car door.Warning device 5 is connected with anti-theft controller 4, and warning device 5 comprises two kinds of audible alarm unit and displaying alarms, and wherein audible alarm unit can be buzzer phone, and displaying alarm can be LCD display.
The warning that this detection automobile key does not pull out is when work, at first anti-theft controller 4 detects in the key 2 whether be inserted with key by anti-theft antenna 3, if key is arranged, then the key 1 of the band theftproof chip in anti-theft antenna 3 and the key 2 carries out the low frequency radio frequency communication and is connected, can make anti-theft controller 4 respond to the antitheft information that obtains in the key 1 by this connection, and anti-theft controller 4 also connects the key 1 of the antitheft authentication command of transmission to key 2 by this, connect by these communications, whether anti-theft controller 4 just can draw the key 1 of the interior band theftproof chip of key 2 by the antitheft algorithm of internal software effective, legal.
Meanwhile, anti-theft controller 4 detects the present state of car door by vehicle door status detecting device 6, if the state of car door for open and key 1 legal effectively, then anti-theft controller 4 control warning devices 5 are reported to the police, audible alarm unit sends alarm sound, displaying alarm sends alarm display, pulls up key when reminding navigating mate to get off.If do not have key in the key 2 or be illegal key through anti-theft controller 4 check keys 1, then warning device 5 can not reported to the police.
Because between anti-theft controller 4 and the key 1 is to carry out the legitimacy that encrypting and authenticating is judged key 1 by antitheft algorithm, so just can judge effectively the legitimacy of key 1, if being illegal key then can not reporting to the police of key interpolation, avoid the interference of illegal key, reduce the probability of flase alarm.
More than a kind ofly detected the warning that automobile key do not pull out and be described in detail what the utility model embodiment provided; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
