Abstract
The utility model discloses a lock in car someone alarm system behind car, including car ECU, still include the system ECU who is connected with car ECU, set up temperature sensor, sound sensor and human infrared ray sensor at the vehicle interior, temperature sensor is connected with the ECU of system through processing circuit and analog to digital conversion circuit, and the sound sensor is connected through processing circuit and voice recognition process circuits and systems ECU, and human infrared ray sensor is connected with the ECU of system through processing circuit and analog to digital conversion circuit. Can be used for automated inspection vehicle status, car internal environment state and che nei whether someone, when the circumstances that unsuitable personnel stayed appearing in the car, alarm system in the automatic start car.
Description
Technical field
The utility model relates in a kind of car locking rear car people's warning.
Background technology
Have people's warning in existing car locking rear car, technical way is on child seat, install sensor or thermal imaging system (infrared ray) additional, for detecting on vehicle seat whether have people.Its major defect is: with high costs, and practicality is not strong, and limiting condition is too much, and reliability is poor, is not suitable for large-batch industrial application.
Utility model content
Technical problem to be solved in the utility model is, there is provided in a kind of car locking rear car and have people's warning, whether there is people for an automatic detection vehicle state, environment inside car state and Che Nei, when there is the situation that the personnel that are not suitable for stay in car, automatically starting in-vehicle alarm system.
The technical solution of the utility model is as follows:
People's warning is had in a kind of car locking rear car, comprise automobile ECU, automobile ECU is connecting automobile engine, motor central lock, auto horn switch and car emergency light switch respectively, characterized by further comprising the system ECU be connected with automobile ECU, be arranged on the temperature sensor of vehicle interior, sound transducer and human infrared sensor; Temperature sensor is connected with system ECU with analog to digital conversion circuit by signal processing circuit, sound transducer is connected with voice identifying processing Circuits and Systems ECU by signal processing circuit, and human infrared sensor is connected with system ECU with analog to digital conversion circuit by signal processing circuit.
It also comprises the wireless communication module be connected with system ECU.
Good effect of the present utility model is:
Vehicle-state is judged by detection car engine state and central controlled lock state, judge with or without personnel in car by human infrared sensor and voice identification sensor, detect vehicle interior temperature to judge whether to exceed human body preference temperature by temperature sensor.Comprehensively determine whether start alarm system, system does respective handling according to preset program by above several condition, judge whether to send alerting signal, start vehicle carried simultaneously and send alarm message to particular kind of relationship people.
Particularly in car locking rear car, leave over child, vehicle interior temperature is too high, and when likely causing the infringement to people, the utility model starts warning, is conducive to protection children by bus.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is further illustrated below in conjunction with drawings and Examples.
With reference to figure 1, the embodiment of native system comprises the system ECU1 as whole system electronic control unit, also comprises the temperature sensor 4, sound transducer 3 and the human infrared sensor 2 that are arranged on vehicle interior.Temperature sensor 4 is connected with system ECU1 with analog to digital conversion circuit by signal processing circuit, sound transducer 3 is connected with voice identifying processing Circuits and Systems ECU1 by signal processing circuit, and human infrared sensor 2 is connected with system ECU1 with analog to digital conversion circuit by signal processing circuit.
The embodiment of native system also comprises the automobile ECU 5 be connected with system ECU1, automobile ECU 5 connecting automobile engine is to obtain driving engine keying signal, automobile ECU 5 connects motor central lock to detect the keying signal of motor central lock and to control motor central lock and open and close, and automobile ECU 5 connects to be opened and the unlatching of car emergency lamp to control horn trumpet as the auto horn switch of automobile acoustic-optic alarm 6 and car emergency light switch.
The embodiment of native system also comprises the wireless communication module 7 be connected with system ECU1, and this wireless communication module 7 is with antenna.
Automobile ECU 5 obtains engine status signal, if driving engine is in operative condition, then judges have navigating mate to exist in car, does not touch alarm system.Automobile ECU 5 obtains motor central lock and to latch signal, if without latching signal, then thinks and has navigating mate to exist or temporaryly to leave, do not touch alarm system, if central controlled lock is in the state of latching, then think that vehicle is in driverless operation state, possess and start alarm system condition precedent.
System ECU1 is detected by human infrared sensor 2, if human body infrared characteristic signal detected, has then thought and has personnel to exist in car.System ECU1 detects aud. snl. by sound transducer 3, if any voice, then thinks and has personnel to exist in car.Infrared ray and voice identification are in parallel, and any one signal exists all thinks have people to exist in car.System ECU1 detects vehicle interior temperature by temperature sensor 4, if temperature is higher or lower than the human body preference temperature of setting, then thinks that occupant is in and is not suitable for the state of staying, meet native system condition.Comprehensive by above five information sensings, after meeting entry condition, delayed circuit start alarm system, object prevents misoperation (vehicle there will not be thermal gradient model formula to change in short-term), after the delay start time arrives, the audible and visual alarm of startup vehicle itself, is made a phone call by wireless communication module 7 and mobile communication network simultaneously or short-message sending notifies car owner, opening vehicle central controlled lock by sending out specific short message signal after car owner knows, reaching the object of rescue occupant.
Sound transducer 3 is a kind of voice identification sensors, belongs to the electronic sensor of sound recognition, by this sensor, experiences external sound, simultaneously by software process, identifies voice.
Human infrared sensor 2, for the electronic sensor of the specific IR wavelength of human body, by this sensor, identifies the presence or absence of occupant.
Temperature sensor 4, for inspection vehicle environment temperature, by the process of this sensor signal, can know that the whether suitable personnel of vehicle interior temperature stay.
Described motor central lock, for controlling door contact interrupter.
Delayed alarm circuit is a kind of illustrative circuitry, when meeting alarm conditions, postpones the misoperation that alarm can prevent the too high wrong report that causes of opening door of vehicle moment vehicle interior temperature and alternate manner.
