For the convenience of understanding, an automobile alarm system provided by the embodiment of the application is described below with reference to the accompanying drawings.
Referring to fig. 1, an architecture diagram of an alarm system for a vehicle is shown, the system 100 comprising: signal acquisition device 102, signal processing device 104 and signal execution device 106. The various components of the system 100 are described in detail below.
The signal acquisition device 102 is used for acquiring automobile state signals and in-automobile living body signals.
The automobile state signal comprises an automobile door lock closing signal and an engine stop signal, and the in-automobile living body signal comprises at least one of a pressure sensor signal and an infrared living body detection signal.
The Sensor (Sensor/Transducer) is a kind of detecting device, which can sense the measured information and convert the sensed information into electric signal or other information in required form according to a certain rule for output, so as to meet the requirements of information transmission, processing, storage, display, record and control.
In some possible implementations, to save development costs, the signal acquisition device 102 acquires the door lock close signal and the engine stop signal from the instrumentation system of the automobile.
The signal acquisition device 102 acquires an infrared living body detection signal from the sensor when the light beam is interrupted.
Acquiring in-vehicle living body signals may include acquiring static living body signals and/or acquiring dynamic living body signals.
In which a static living body signal can be transmitted by a Pressure Transducer (Pressure Transducer). Optionally, pressure sensor can install on just passenger seat and back row passenger seat, and when someone sat or when moving on the car seat, pressure type sensor atress consequently can be according to certain law with the pressure conversion that receives for the signal of telecommunication send for the singlechip. The main working principle of the pressure sensor is as follows:
wherein R is resistance, rho is resistivity of the metal conductor, S is cross-sectional area of the conductor, and L is length of the conductor.
Dynamic human detection is confirmed by a photo electric Beam Detector (photechoelestic Beam Detector); the accuracy of obtaining the signal of whether a person is in the vehicle can be ensured through dynamic human body detection and static human body detection.
In order to detect whether there is a dynamic living body in the vehicle, a Beam-blocking sensor (Photoelectric Beam Detector) may be used. The beam interruption type sensor has the main advantages that the transmitting power can be automatically adjusted according to the environment condition, so that the change of the surrounding environment can be sensed, and the full self-adaption to the environment is completely realized; meanwhile, artificial intelligence fuzzy recognition is adopted, so that the error rate is low. Specifically, when a living object is in the protective area in the vehicle, the invisible infrared ray light speed can be intercepted, and the light beam intercepting type sensor can receive the intercepted invisible infrared ray light beam and process the light beam into an intercepting electric signal to send the single chip microcomputer.
The in-vehicle living body signal acquisition unit can acquire one of a static living body signal and a dynamic living body signal, and can also acquire the static living body signal and the dynamic living body signal at the same time.
The signal processing device 104 is used for identifying whether a living body is locked in the automobile or not according to the automobile state signal and the automobile living body signal.
Specifically, when the signal received by the signal processing device 104 indicates that the engine of the automobile stops rotating, the doors and windows of the automobile are closed, and the in-automobile living body signal indicates that a living body is present in the automobile, the signal processing device 104 determines that the living body is locked in the automobile.
Optionally, when a signal of a living body in the vehicle is acquired, a signal of a static living body and a signal of a dynamic living body are acquired at the same time, and as long as one signal represents that the living body exists in the vehicle, the living body is considered to exist in the vehicle.
Optionally, when the in-vehicle living body signal is acquired, a static living body signal and a dynamic living body signal are acquired simultaneously, and when the two signals simultaneously represent that the in-vehicle living body exists, the in-vehicle living body is considered to exist.
Preferably, the signal processing device 104 may be a single chip microcomputer. The Single-Chip Microcomputer is an integrated circuit Chip, which is a small and perfect Microcomputer system formed by integrating the functions of a central processing unit CPU with data processing capacity, a random access memory RAM, a read-only memory ROM, various I/O ports, interrupt systems, timers/counters and the like (possibly comprising circuits such as a display driving circuit, a pulse width modulation circuit, an analog multiplexer, an A/D converter and the like) on a silicon Chip by adopting a large-scale integrated circuit technology, and is widely applied to the field of industrial control.
Specifically, a single chip with 28 pins can be selected, as shown in fig. 2, an MSP430G2553 chip is selected, the single chip has a 16KB flash memory, a 512BSRAM, a 10-bit ADC, a comparator, a UART/SPI/12C, and a 16MHz MCU with a counter, and the corresponding pins are shown in fig. 3, and the single chip can be programmed according to a pin design.
Of course, a 51-chip microcomputer, an STC-chip microcomputer, a freescale-chip microcomputer, an AVR-chip microcomputer, etc. may also be selected, and the application is not limited herein.
In some possible implementations, the signal acquisition device 102 is instructed to stop acquisition when it is identified that no living body is locked in the automobile for N consecutive times according to the automobile state signal and the in-automobile living body signal. For example, when the signal acquisition device 102 detects that the engine stops rotating and the door has been locked, and both the static human body detection signal and the dynamic human body detection signal are 0, the signal processing device 104 determines that no one is locked in the automobile, the system starts a continuous detection program every 2 minutes, and the system stops when the obtained signal still indicates that no one is present during the third detection; the alarm signal is executed when there is no person in reality. Wherein, the number of continuous identification times and the system interval time can be set by a technician or a user.
The signal execution means 106 is used for giving an alarm when the signal processing means 104 recognizes that a living body is locked in the automobile.
In some possible implementations, the signal executing device 106 may be composed of a GSM short message system and a sound alarm system.
Wherein the signal executing device 106 can communicate with the signal processing device 104 through wireless communication. Specifically, when the signal processing device 104 obtains the electrical signal and detects that someone is in the automobile, the signal processing device 104 sends an electrical signal AT command to the GSM module through the serial port to perform communication.
Specifically, the GSM short message system executes the short message alarm function, and when the signal processing device 104 analyzes and processes the signal and finds that a living object is locked in the automobile, the signal executing device 106 sends a short message to the driver through the GSM short message function module of the system, and informs the driver that a living object is locked in the automobile, so that the driver returns to the automobile for rescue.
When the signal processing device 104 analyzes and processes the signal and finds that the signal is that a living object is locked in the automobile, the signal executing device 106 sends the signal through an automobile horn connected in the system, so that the horn sounds to attract the attention of people around the automobile and achieve the purpose of rescue. Optionally, in order to save cost, an automobile horn may be used.
In some possible implementations, the signal executing device 106 includes an audible alarm, and/or a sending device, and specifically, when the signal executing device 106 receives a signal that the living body is locked in the automobile and sent by the signal processing device 104, the signal executing device 106 alarms through the audible alarm; and/or sending an alarm message to the specified object for alarming.
In other possible implementations, when the signal execution device 106 receives a signal that the living body is locked in the automobile and is sent by the signal processing device 104, the signal execution device 106 alarms through the whistle of the automobile; and/or sending an alarm message to the specified object through the mobile communication module.
Wherein, can make audible alarm connect the car horn system of whistling through designing drive circuit, drive circuit shows as figure 4, when the signal of telecommunication that signal processing device 104 obtained detects someone in the car, sends the buzzing signal of telecommunication for drive circuit, and the buzzing signal of telecommunication is through triode, MOSFET metal oxide semiconductor field effect transistor with signal of telecommunication current amplification, through drive circuit, drives the car and whistles the horn and send alarm signal.
Therefore, when the automobile engine stops rotating and the automobile door is locked, whether people or pets exist in the whole automobile space can be automatically detected, if people or pets remain on the automobile, the automobile safety alarm system sends out an alarm signal, and the alarm signal can attract the attention of people around the automobile so as to achieve the purpose of rescue; and a danger signal is sent to the driver through a short message function module of GSM wireless communication, so that the driver returns to rescue.
