Description
Technical field
The present invention relates to the technical fields that automotive safety uses, and are concretely related to a kind of caravan alarm system.
Background technique
Currently, the development of caravan is swifter and more violent, the trip tool that caravan is used to travel outgoing is more and more common, but outside
During out, antitheft, the safety of caravan and interior articles become caravan user increasingly focus of attention.In travelling process
In, caravan generally can all be parked in scenic spot or suburb, and during going out for an excursion, playing, car is easy to be stolen;Or it camps overnight in
In caravan, the safety of caravan is also worthy of consideration, caravan be can rest in the car overnight, the family that even has be with caravan
Room, so caravan security protection is extremely important.On existing caravan, there is a back door by the room of caravan car owner rest, this
Back door is easy to be pried open by National People's Congress's power, so that threatening interior personal safety as well as the property safety.
In the prior art in order to improve the safety of caravan, car alarm, automobile burglar are usually installed on caravan
The working principle of device is after generating gravity sensing after object is touched, and car alarm can just sound an alarm, therefore in reality
Daily life in, only when caravan has received certain damage, the alarm of car alarm can just sound, endanger at this time
Occur already, so this car alarm can not be taken precautions against in advance, can only could alarm after being damaged, there is centainly stagnant
Property afterwards cannot effectively guarantee the safety of caravan, be unable to satisfy the demand of the majority of consumers.
Summary of the invention
Therefore the present invention propose a kind of caravan alarm system, for solve current caravan be only collided just issue warn
Report, alarm issue not in time, cannot timely and effectively guarantee the problem of caravan safety.
The technical scheme of the present invention is realized as follows: a kind of caravan alarm system, including human body infrared induction module, letter
Cease processing module, power module and alarm output module;
Power module, for being human body infrared induction module, message processing module and alarm output module provide power supply;
Human body infrared induction module, the human body induction module is interior to be equipped with transmitting probe and receiving transducer, and transmitting probe is used
The object close to back door is detected in transmitting infrared ray, when having detected that object is close, returns to infrared signal to reception
Probe, receiving transducer export infrared signal to message processing module;The level detection angle of the transmitting probe and receiving transducer
It is 10 ° -20 °;
Message processing module for receiving infrared signal, and carries out processing to infrared signal and is converted to voltage value signal, will
Voltage value signal, which exports, gives alarm output module;
, when voltage value is greater than the set value, alarm signal occurs for alarm output module for receiving voltage value signal.
When caravan car owner is located at interior rest, system starts to initialize, and starts human body infrared induction module, information processing mould
Block and power module are furnished with infrared ray at the back door of caravan, when horizontal distance of the external staff close to caravan back door is 50CM-
When 60CM, the detection range of human body infrared induction module, the infrared signal that human body infrared induction module will test have been entered
It exports to message processing module.
The infrared signal received is converted to voltage value signal by message processing module, if the voltage value received reaches alert
When reporting the setting value of output module, the work of alarm output module is just triggered, to sound an alarm, reminds the personnel in caravan alert
It guards against, personnel and property in caravan is avoided to incur loss.
It further, further include caravan carriage and back door;The contact position at caravan carriage and back door is provided with the first groove, and first
The first cavity and the second cavity are equipped in groove, the first cavity is provided with aluminum sulfate solution, and the second cavity is provided with sodium bicarbonate
Solution, the first cavity bottom are provided with first outlet, and the second cavity bottom is provided with second outlet, first outlet and second outlet phase
The upper end of neighbour, first outlet and second outlet is equipped with baffle, is equipped with air bag below the first cavity and the second cavity, air bag is opened
Mouth is opposite with first outlet and second outlet, and the controller of control barrier switch is equipped in the first groove, and the one of controller
End is electrically connected with baffle, and the other end of controller is electrically connected with alarm output module;The second groove is provided in the doorframe at back door.
After controller receives voltage value signal, controller will control baffle movement, by first outlet and second outlet
It opens, then aluminum sulfate solution enters air bag from first outlet outflow, and sodium bicarbonate solution enters air bag from second outlet outflow,
Aluminum sulfate solution and the sodium bicarbonate solution hybrid reaction in air bag generate gas, expand entire air bag rapidly the first groove
It fills up, while being inserted into second groove at back door, so that all crack between a door and its frames at back door be blocked.
If there is nonnative personnel will poke air bag with tool insertion crack between a door and its frame by force to prize back door, due to having gas in air bag
And pressure is larger, can gush out a large amount of gas rapidly when nonnative personnel pokes air bag, the gas is harmless, can be right
Nonnative personnel plays the role of fright, guarantees the safety of property in caravan carriage.
Further, the level detection angle of the transmitting probe and receiving transducer is 15 °, and detection angle is small, more
It, can be to avoid erroneous judgement close to caravan.
Further, the human body infrared induction module includes IR remote controller and infrared-reflectance sensors;Infrared remote control
Device, for controlling opening or closing for infrared-reflectance sensors;Infrared-reflectance sensors, for emitting infrared ray and detecting whether
There is infrared signal return;The message processing module is processor platform;The power module is caravan power supply;The alarm is defeated
Module is alarm out.
Further, the output end of the power module is connected with message processing module, human body infrared induction module it is defeated
Outlet is connected with message processing module, and the output end of message processing module is connected with alarm output module.
Further, the setting value is greater than 1.35V.
Further, the infrared-reflectance sensors are mounted on the vertical range on caravan and apart from ground greater than 1M, can
It causes to judge by accident to prevent the animals such as cat and dog and some children from approaching.
Further, the infrared-reflectance sensors are mounted on the rearview mirror of caravan, infrared-reflectance sensors and caravan
Back door be located at the same side, infrared-reflectance sensors are mounted on rearview mirror, and the infrared line length of sending can achieve 5M, just
The later length of the rearview mirror of caravan is enumerated, whole detection is realized, improves the validity of detection.
By above disclosure, the invention has the benefit that by the way that human body infrared is arranged on caravan in the present invention
Induction module can remind car owner before caravan is damaged, to be taken precautions against ahead of time, can timely and effectively guarantee room
Vehicle safety.
Simultaneously because human body infrared induction module of the invention is equipped with transmitting probe and receiving transducer, compared to common human body
It can be realized simultaneously transmitting and reception for only one probe of infrared induction module, the detection of transmitting probe and receiving transducer
Angle is 10 ° -20 °, only when people close to caravan back door 50CM-60CM apart from when, alarm can just sound, and in this way may be used
To improve the detection validity of human body infrared induction module, the case where reporting by mistake generation is avoided while can preventing ahead of time.
