Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the invention without making creative efforts, fall within the scope of the invention; any equivalent substitution or simple modification of any module of the invention is within the scope of the invention.
As shown in fig. 1, the emergency (people are trapped) working principle is that when 1. the temperature detection module detects that the trend temperature reaches a specific value or 2 the oxygen concentration and the carbon monoxide detection integrated module detects that the trend oxygen concentration or the trend carbon monoxide concentration reaches a specific value, (one of the three modules can) sends an electric signal to the 5 central controller module, the 5 central controller module controls the 3 microwave induction module to start an alarm program (the program is gradually increased and is not independently operated) after the 3 microwave induction module detects that an object in the vehicle reaches a specific movement time within a first movement time, and the program is that: 5, the central controller module controls 7 speakers in the vehicle to give out prompt tones to prompt people in the vehicle that the temperature, oxygen concentration or carbon monoxide concentration are not suitable for the people to stay for a long time, and if the trend temperature, trend oxygen concentration or trend carbon monoxide concentration causing the alarm reason reaches a specific value after a specific time, a program is started: 5 speaker sends warning sound suggestion car around 7 outer cars of central controller module control crowd, the positional information who simultaneously controls 6 wireless communication module and combine 4 locators to collect sends the SMS for mobile terminal or intelligent household electrical appliances who bind, APP information, dial the phone, APP video conversation etc, the suggestion is in danger for someone in the car, the terminal accessible SMS that binds, the phone, APP replies receives the information, also can look over video information in the car and 7 car interior speaker pacify personnel of accessible through APP, and decide whether to interrupt follow-up procedure, if 6 wireless communication module do not receive the reply and 5 central controller module receive the trend temperature that leads to the signal of warning reason after the specific time, when trend oxygen concentration or trend carbon monoxide concentration reach specific numerical value, start-up procedure third in the car: 5, the central controller module sends the position information transmitted by the locator combined with the locator 4 to terminal customer service personnel and police service personnel; if the step 5, the central controller module receives a door opening signal of the microwave induction module 3 or a door opening signal detected by the ZigBee door sensor gateway system 8, the central controller module 5 in a specific time receives a signal of trend temperature reduction, trend oxygen concentration increase or trend carbon monoxide concentration reduction, an alarm program is stopped, the user is prevented from continuing to give an alarm after being detained by children, if the specific time later, the central processor 5 detects that the trend temperature reaches a specific value through the temperature detection module 1 for analyzing the reason of alarm, the oxygen concentration and carbon monoxide concentration detection integration module 2 detects that the trend oxygen concentration increases to a specific value or the trend carbon monoxide concentration reaches a specific value, and the central controller 5 controls the microwave induction module 3 to start the related central controller according to the detected value after the specific time later reaches a specific movement time after the object in the vehicle is detected by the microwave induction module for the first time And the second step, the third step, alarming.
The working principle of the ordinary (using the automobile after high-temperature weather) is that when a temperature detection module 1 in the automobile detects that the trend temperature reaches a specific value, an electric signal can be sent to a central controller module 5, the central controller module 5 controls a microwave induction module 3 to not detect that an object in the automobile moves until the central controller module 5 receives a door opening signal of the microwave induction module 3, a door opening signal is detected by an 8ZigBee door sensor gateway system, and the central controller module 5 does not start an alarm program when receiving a signal that the trend temperature is reduced, the trend oxygen concentration is increased or the trend carbon monoxide concentration is reduced within a specific time. If the [0019] condition appears after a specific time, the situation that a person mistakenly enters the automobile in the midway is judged to be trapped, and then the automobile is treated according to the [0019] principle.
The invention does not need a professional technician to connect the device with a vehicle body, solves the construction problem, and has the principle that whether the environment in the vehicle threatens the safety of people or not is judged by means of three sensors of temperature, oxygen concentration and carbon monoxide concentration, an accurate application scene is provided for subsequent work, a microwave detection distance is set at the same time, a microwave detection area is regulated to be an inner space below a vehicle window by adjusting the angle of a microwave detector, a metal shell is arranged below 99 percent of the vehicle window in the current market, microwaves cannot penetrate through the lower part of the vehicle window, so that the interference of objects outside the vehicle is avoided, the detection accuracy is ensured, whether movable objects exist in the vehicle or not is judged by utilizing the penetrability of the microwaves to non-metal objects and the Doppler effect, the alarm is given after the object in the vehicle reaches a specific moving time after the object in the vehicle is firstly moved, the false alarm is avoided, and meanwhile, reflected wave signals of the microwaves or signals detected by a ZigBee door And judging the opening and closing of the vehicle door, and determining to start or not to start an alarm program by judging the rising or falling of the received signals of the trend temperature, the trend oxygen concentration or the trend carbon monoxide concentration in a specific time by the central controller module.
The above description is only for the preferred embodiment of the present invention and is not intended to be limiting in any way, and any variations and modifications of the above embodiments or combinations of optional parts based on the technical spirit of the present invention are within the technical scope of the present invention.
