The reminding device can give a prompt tone to remind a car owner of locking the car door when a car owner leaves the car without locking the car door, thus, car theft or loss of belongings in the car is avoided.
Description
Technical field
The utility model relates to a kind of automobile alarm set, relates in particular to a kind of car non-locking door alarm set.
Background technology
The switch of existing automobile normal operation key or remote controller control Door Lock.Although the car owner has shut car door sometimes when leaving automobile, can forget to lock door, and existing automobile does not remind the car owner to note the device of car non-locking door, thereby cause damage to property in vehicle thefts or the car.
China Patent Publication No. CN201626349U, open day on November 10th, 2010, the name of utility model is called a kind of door contact interrupter annunciator, this application case discloses a kind of door contact interrupter annunciator, it comprises automobile power source, relay, the car light interface, front car light, rear car light, two metallic contacts, the low pressure time-delay switch, two metallic contacts are close to respectively and are installed on car door and the door frame, the trigger end of described relay, one end directly is electrically connected with a metallic contact, the other end is electrically connected with another metallic contact by automobile power source, the switch terminals of described relay and be parallel with the car light interface on the normal beginning, described low pressure time-delay switch is installed on the car door, and join with Chang Kaiduan and the normal-closed end of relay, described car light interface is respectively by wire and front car light, rear car light joins.Its weak point is, this annunciator can only be lighted front car light and rear car light when car door is not shut, and forgets that the car owner when locking door, this annunciator can't the warning reminding car owner be noted the car non-locking door.
The utility model content
The purpose of this utility model is to overcome to forget when the car owner leaves automobile sometimes and lock door, cause the technical matters of damage to property in vehicle thefts or the car, a kind of car non-locking door alarm set is provided, it is forgotten when locking door the car owner, can send prompt tone, remind car owner's car non-locking door.
In order to address the above problem, the utility model is achieved by the following technical solutions:
A kind of car non-locking door alarm set of the present utility model, comprise central processing unit, micro-switch, automobile door lock state detection module, prompting module and power module, described central processing unit links to each other with power module with micro-switch, automobile door lock state detection module, prompting module respectively, described micro-switch is arranged in the lockhole of ignition lock, and described automobile door lock state detection module is arranged in the automobile door lock.
In the technical program, power module is the power supply of car non-locking door alarm set.After the car owner extracted car key in the lockhole of ignition lock, the micro-switch in the lockhole disconnected, and sends start pulse signal to central processing unit.Central processing unit is processed the start pulse signal that receives, and the startup internal timer begins timing.The automobile door lock state detection module detects the status information of automobile door lock, and sends it to central processing unit.When the internal timer timing reached predefined time upper limit value, central processing unit was judged the state of automobile door lock.
If automobile door lock is not locked, central processing unit starts prompting module work, and prompting module is sent prompt tone, and reminding driver is locked car door; If automobile door lock is locked, the central processing unit controls prompting module is not worked, the internal timer zero clearing.
As preferably, described automobile door lock state detection module is the position transduser of inspection vehicle lock core linkage board location status.When automobile door lock was in release or lockup state, when namely the vehicle door lock linkage board was positioned at unlocked position or lock position, position transduser sent different electric signal to central processing unit.
As preferably, described prompting module comprises speech chip and loud speaker, and described central processing unit links to each other with speech chip respectively with loud speaker.When automobile door lock was not locked within the default time, central processing unit transmitted control signal to speech chip, and the speech chip control loudspeaker sends voice reminder sound, and reminding driver is locked car door.
As preferably, described a kind of car non-locking door alarm set also comprises key groups, and described key groups links to each other with central processing unit, and is arranged on the vehicle console.The car owner can arrange by key groups the time upper limit value of the internal timer timing of central processing unit.
As preferably, described central processing unit is car body controller BCM.
The beneficial effects of the utility model are: forget and can send prompt tone when locking door when the car owner leaves automobile, remind car owner's car non-locking door, avoid damage to property in vehicle thefts or the car.
Description of drawings
Fig. 1 is that a kind of circuit theory of the present utility model connects block diagram.
Among the figure: 1, central processing unit, 2, micro-switch, 3, the automobile door lock state detection module, 4, prompting module, 5, power module, 6, speech chip, 7, loud speaker, 8, key groups.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of car non-locking door alarm set of present embodiment, as shown in Figure 1, comprise central processing unit 1, micro-switch 2, automobile door lock state detection module 3, prompting module 4, power module 5 and key groups 8, prompting module 4 comprises speech chip 6 and loud speaker 7, central processing unit 1 respectively with micro-switch 2, automobile door lock state detection module 3, speech chip 6, power module 5 and key groups 8, speech chip 6 also links to each other with loud speaker 7.Micro-switch 2 is installed in the lockhole of ignition lock, and key groups 8 is installed on the vehicle console, and central processing unit 1 is car body controller BCM.
Automobile door lock state detection module 3 is the position transduser of inspection vehicle lock core linkage board location status, and is installed in the automobile door lock.When automobile door lock was in release or lockup state, when namely the vehicle door lock linkage board was positioned at unlocked position or lock position, position transduser sent different electric signal to central processing unit 1.
