Description

Technical Field

[0001] The invention belongs to the technical field of emergency escape systems, and in particular relates to an intelligent window-breaking escape system based on a single-chip microcomputer. Background Art

[0002] In emergency situations, such as fires, traffic accidents or natural disasters, people need to escape from dangerous areas quickly. However, in some cases, such as when a vehicle falls into water, a tram catches fire or a collision causes difficulty in rescue, the available escape methods may be limited. Traditional escape methods, such as using a safety hammer to break a window, have problems such as complex operation, high force requirements, and long time consumption. In emergency situations, people are often unable to escape quickly and effectively due to psychological factors such as tension and panic. At this time, an escape system that can automatically break windows is particularly important. It can provide a life channel for trapped people at a critical moment.

[0003] In view of this, an intelligent window-breaking escape system based on a single-chip microcomputer is proposed. Summary of the invention

[0004] In order to solve the problems of traditional escape methods such as using a safety hammer to break a window, which have complex operations, high force requirements, and long time consumption, and in an emergency, people are often unable to escape quickly and effectively due to psychological factors such as tension and panic, the basic concept of the technical solution adopted by the present invention is:

[0005] An intelligent window-breaking escape system based on a single-chip microcomputer comprises a mode switching module, a monitoring module, a directional window-breaking module, a single-chip microcomputer and a peripheral circuit module, wherein the mode switching module comprises a manual window-breaking control module, a temperature sensor module, a water pressure sensor module and a vibration sensor module, wherein the mode switching module is composed of four modes: a manual window-breaking mode controlled by a double safety insurance button, a fire window-breaking mode monitored by a temperature sensor, a water-falling window-breaking mode monitored by a water pressure sensor and an impact deformation window-breaking mode monitored by a vibration sensor, wherein the monitoring module is an oxygen content monitoring module, wherein the directional window-breaking module is composed of a circular bore tube, a motor bore-pressing device, a pop-up device, a window-breaking structure and a stress sensor, wherein the window-breaking structure uses diamond as an effective material for directional window-breaking, wherein the directional window-breaking module is popped out from the circular bore tube by a program-controlled manner, and wherein the directional window-breaking module determines whether a secondary knock is required by a stress sensor to ensure the reliability of the directional window-breaking operation.

[0006] As a preferred implementation of the present invention, the manual window breaking control module is jointly confirmed to be effective by two buttons to prevent the risk of accidental touch.

[0007] As a preferred embodiment of the present invention, the temperature sensor module sets a certain threshold value so that the window breaking takes effect immediately when a car explosion occurs.

[0008] As a preferred embodiment of the present invention, the water pressure sensor module sets a certain threshold value so that the window breaking takes effect immediately after the car falls into water and the water pressure reaches a certain value.

[0009] As a preferred embodiment of the present invention, the vibration sensor module monitors the stress threshold and breaks the window immediately when a car accident causes collision deformation.

[0010] As a preferred embodiment of the present invention, the oxygen content monitoring module can assist in enhancing the reminder of the risk of suffocation caused by air conditioning in a confined space in the vehicle.

[0011] As a preferred embodiment of the present invention, the motor chamber pressing device and the ejecting device are driven by a single chip microcomputer. The stress sensor determines whether to perform a secondary knocking task by monitoring the stress size after the knocking is performed. If a secondary knocking is performed, a signal is sent back to the single chip microcomputer. The single chip microcomputer drives the motor chamber pressing device to drag the diamond window breaking structure back to the initial position.

[0012] As a preferred embodiment of the present invention, the peripheral circuit module is powered by an independent power supply to prevent the risk of vehicle short circuit or other power supply failure. The power supply adopts a ternary lithium battery and is combined with a solar circuit board to achieve green circulating power supply.

[0013] As a preferred embodiment of the present invention, the manual window breaking control module, temperature sensor module, water pressure sensor module, vibration sensor module and oxygen content monitoring module are transmitted to the single-chip microcomputer through the SPI transmission bus for judgment, and the window breaking state of the directional window breaking module is started.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention solves the problem of difficulty in escaping a car in special scenarios such as collision, falling into water and fire. By realizing the self-monitoring function of the vehicle status, the intelligent directional window breaking function can be completed. When necessary, the directional window breaking can also be manually controlled to increase the chance of escape in special risk scenarios.

[0016] The present invention monitors the threshold information of accidental injuries of concern by means of multi-sensor fusion, and then utilizes the SPI bus to transmit the monitored signal to the single-chip microcomputer for analysis. If a sensor obstacle occurs, the window breaking task can also be performed manually. In the process of executing the intelligent directional window breaking task, the single-chip microcomputer sends a pop-up command, the diamond device pops up and hits the car window, and then monitors the threshold of the pressure sensor on the diamond device. If it exceeds a certain threshold, the window is not broken successfully, and the single-chip microcomputer needs to start the chamber pressing operation. After the stepper motor runs, the diamond window breaking device is dragged back to the initial position, and the secondary window breaking task is performed until the window breaking is successfully completed, so as to ensure the smooth execution of the window breaking task.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0022] like Figure 1 to Figure 2 Shown

[0023] An intelligent window-breaking escape system based on a single-chip microcomputer includes a mode switching module, a monitoring module, a directional window-breaking module, a single-chip microcomputer and a peripheral circuit module. The mode switching module includes a manual window-breaking control module, a temperature sensor module, a water pressure sensor module and a vibration sensor module. The mode switching module consists of four modes: a manual window-breaking mode controlled by a double safety insurance button, a fire window-breaking mode monitored by a temperature sensor, a water-falling window-breaking mode monitored by a water pressure sensor and an impact deformation window-breaking mode monitored by a vibration sensor. The monitoring module is an oxygen content monitoring module. The directional window-breaking module consists of a circular bore tube, a motor-pressurized bore device, a pop-up device, a window-breaking structure and a stress sensor. The window-breaking structure uses diamond as an effective material for directional window-breaking. The directional window-breaking module pops up from the circular bore tube through a program-controlled manner. The directional window-breaking module determines whether a second knock is required through a stress sensor to ensure the reliability of the directional window-breaking operation. The motor-pressurized bore device and the pop-up device The device is driven by a single-chip microcomputer. The stress sensor determines whether to perform a secondary knocking task by monitoring the stress size after the knocking is performed. If a secondary knocking is performed, a signal is sent back to the single-chip microcomputer. The single-chip microcomputer drives the motor to press the chamber device to drag the diamond window breaking structure back to the initial position. The manual window breaking control module, temperature sensor module, water pressure sensor module, vibration sensor module and oxygen content monitoring module are transmitted to the single-chip microcomputer through the SPI transmission bus for judgment, and the directional window breaking module starts the window breaking state. During the execution of the intelligent directional window breaking task, the single-chip microcomputer sends a pop-up command, the diamond device pops up and hits the car window, and then monitors the threshold of the pressure sensor on the diamond device. If it exceeds a certain threshold, the window is not broken successfully, and the single-chip microcomputer needs to start the pressing operation. After the stepper motor runs, it drags the diamond window breaking device back to the initial position to perform the secondary window breaking task until the window breaking is successfully completed to ensure the smooth execution of the window breaking task.

[0024] In a specific implementation, the manual window breaking control module is jointly determined by two buttons to prevent the risk of accidental touch. The temperature sensor module sets a certain threshold value, and the window breaking takes effect immediately when the car explodes; the water pressure sensor module sets a certain threshold value, and the window breaking takes effect immediately after the car falls into the water and the water pressure reaches a certain value; the vibration sensor module monitors the stress threshold value, and the window breaking takes effect immediately when the car accident causes collision deformation; the oxygen content monitoring module can assist in raising the suffocation risk reminder caused by the air conditioner in the confined space in the car. The threshold information of the accidental injury of concern is monitored by multi-sensor fusion, and the monitored signal is transmitted to the single-chip microcomputer for analysis by using the SPI bus. If there is a sensor obstacle, the window breaking task can also be performed manually.

[0025] Furthermore, the peripheral circuit module is powered by an independent power supply to prevent the risk of vehicle short circuit or other power supply failure. The power supply adopts a ternary lithium battery and is combined with a solar circuit board. The intelligent window-breaking escape system is placed in the lower left corner of each window, at a certain distance from the window so as not to affect the lifting of the window. The power supply adopts a solar panel embedded in the frame of the window joint to power the ternary lithium battery, which can realize green circulating power supply.

[0026] The implementation principle of an intelligent window-breaking escape system based on a single-chip microcomputer in this embodiment is as follows:

[0027] During specific use, the intelligent window breaking escape system is placed in the lower left corner of each car window, at a certain distance from the car window so as not to affect the lifting of the car window. The power supply uses a solar panel embedded in the frame at the connection of the car window to power the ternary lithium battery, and then monitors the threshold information of the accidental injury of concern through multi-sensor fusion, and then uses the SPI bus to transmit the monitored signal to the single-chip microcomputer for analysis. If there is a sensor obstacle, the window breaking task can also be performed manually. During the execution of the intelligent directional window breaking task, the single-chip microcomputer sends a pop-up command, the diamond device pops up and hits the car window, and then monitors the threshold of the pressure sensor on the diamond device. If it exceeds a certain threshold, the window is not broken successfully, and the single-chip microcomputer needs to start the chamber compression operation. After the stepper motor runs, the diamond window breaking device is dragged back to the initial position to perform the secondary window breaking task until the window breaking is successfully completed to ensure the smooth execution of the window breaking task.
