WINDOW BREAKING SYSTEM IN AN EMERGENCY
BACKGROUND
Technical Field
The present invention relates to passive safety technologies, and in particular, to a 5 window breaking system in an emergency.
Related Art
In February 18, 2003, a fire broke out at Central Road Station of the subway in Taegu Korea, and 198 people were killed, 146 injured, and 298 missing. The subway fire in Taegu Korea sounded an alarm for the world. As a symbolic project of a modem metropolis, a subway system is both an underground project and a public gathering place. Because of the limited space and dense population of the subway, once a disastrous accident such as a fire, a collision, a rollover, drowning, or a terrorist attack happens, huge casualties and economic losses may be caused. Therefore, the safety problem of the subway is extremely important.
Once an unexpected accident happens in a vehicle, how to quickly escape from the vehicle in a relatively enclosed space seems particularly important. If measures are not taken in time, or necessary self-rescue measures are not taken, the life and property security of the driver and the passengers may be threatened.
At present, a relatively popular emergency means used in a subway, a train, and a high-speed train is, for example, providing a firefighting device and a manual window breaking hammer in the train. However, the use of the firefighting device and the manual window breaking hammer needs some skills, and even people with the skills may be at a loss in a panic. For example, when an emergency such as a fire/poison gas incident happens in a train/subway/urban rail system, many passengers cannot use a window breaking hammer in a correct way to break windows, and windows of the train are solid (for example, double-glazing glass) and cannot be easily broken by using the manual window breaking hammer. The emergency handling skills of people in different carriages may vary, the glass-breaking of some carriages costs too much time, and escape chances are missed.
Based on the foregoing phenomenon, an automatic window breaking technology in a train is still available in the industry and market, and so far, there is no related product or technical solution to resolve the problem. The inventor, Mr. Tong Yang, researches and designs a suitable technical means to resolve the problem, based on his previous invention (application NO. 201410812556.0 entitled AUTOMATIC WINDOW EXPLOSION SYSTEM AND TRANSPORTATION MEANS WITH THE SYSTEM) and with respect to the running characteristics of a train.

DETAILED DESCRIPTION
The following describes the present invention in detail with reference to the accompanying drawings and in combination with embodiments. It should be noted that, without conflicts, the embodiments in the present invention and features in the embodiments may be combined with each other.
The present invention provides a window breaking system in an emergency, which may be applied to a train and fire safety of a common building. An existing controller (for example, a vehicle control unit) and an explosive window breaker (execution component) are used to automatically break a window in an emergency (a fire, a vehicle rollover, or other particular situations), and increase escape chances for passengers.
Further, a train is used as an example to describe the window breaking system of the present invention. As shown in FIG. 1, in this embodiment, the window breaking system may be used to break train window glass in an emergency. In a first embodiment of the present invention, the window breaking system is applied to a train with at least two carriages, for example, in carriages. The window breaking system includes a central control unit 110, a window breaker control unit (WBCU) 120 of a first carriage, a WBCU 122 of a second carriage, and a WBCU 124 of an nth carriage that are connected by using a field bus 130, where n is an integer greater than 1.
Further, referring to FIG. 2, the central control unit 110 receives information of the WBCU of each carriage by using a field bus interface, where the information includes but is not limited to information about a detection signal, a warning light, and a buzzer, and sends a warning and control signal when the vehicle is out of control. The central control unit 110 includes an algorithm control and drive circuit 112, configured to receive information from the WBCUs of the first to the nth carriages, and send a warning and control signal. Further, the central control unit 110 further includes a display, configured to display various information, and the display may be one or more of a liquid crystal display, an electronic dashboard, or buzzers and indicators that respectively indicate different carriages.
The formations and working principles of the WBCUs of the first to the nth carriages are the same. Therefore, FIG. 2 only shows functional modules of the WBCU 120 of the first carriage. The WBCU 120 of the first carriage includes a window breaker control unit 1201 and a detection unit 1202. The detection unit 1202 includes a temperature sensor 1204, a smoke sensor 1206, and a photographing apparatus 1208. The window breaker control unit 1201 includes an electrical initiation window breaker 1203, and the electrical initiation window breaker 1203 may be a window breaking switch.
The central control unit 110 controls the WBCU of each carriage by using the field bus 130 in the train, to avoid any unnecessary and unexpected window breaking action.
The central control unit 110 is further connected to a manual control switch ill disposed in a central control room of the train, and may be started by a train driver by pressing a single button in the central control room, so as to break all glass of the entire train in an emergency. The system must be controlled by the train driver in a centralized manner, to avoid any unexpected or unnecessary window breaking action.
The central control unit 110 receives a signal from the detection unit 1204 of the WBCU of each carriage. That is, the central control unit 110 monitors, in a centralized manner, the smoke concentration and temperature of each carriage, and/or field images collected by the photographing apparatus 1206, and the WBCU of each carriage cyclically sends temperature, smoke, and photographing information to the central control unit 110. The central control unit 110 processes the information from each carriage, detects which carriage's window needs to be broken, and sends a window breaking request to a glass breaker control unit 1201 of the corresponding carriage, and a corresponding electrical initiation window breaker 1203 executes a window breaking action according to the received request.
In a second embodiment, the train may further automatically break a window below a limited speed, to avoid secondary damage caused by window breaking when the vehicle is at a high speed.
Specifically, as shown in FIG. 3 and FIG. 4, the window breaking system includes a central control unit 210, a WBCU 220 of a first carriage, a WBCU 222 of a second carriage, and a WBCU 224 of an nth carriage that are connected by using a field bus 230. Different from the first embodiment, the window breaking system further includes an engine control unit 240 and a brake control unit 250 that are connected to the field bus 230.
Further, referring to FIG. 2, the central control unit 210 receives information of the WBCU of each carriage by using a field bus interface, where the information includes but is not limited to information about a detection signal, a warning light, and a buzzer, and sends a warning and control signal when the vehicle is out of control. The central control unit 210 includes an algorithm control and drive circuit 212, configured to receive information from the WBCUs of the first to the nth carriages, and send a warning and control signal. Further, the central control unit 210 further includes a display, configured to display various information, and the display may be a liquid crystal display, an electronic dashboard, or buzzers and indicators that respectively indicate different carriages.
The formations and working principles of the WBCUs of the first to the nth carriages are the same. Therefore, FIG. 4 only shows functional modules of the WBCU 220 of the first carriage. The WBCU 220 of the first carriage includes a window breaker control unit 2201 and a detection unit 2202. The detection unit 2202 includes a temperature sensor 2204, a smoke sensor 2206, and a photographing apparatus 2208. In this embodiment, the detection unit 2202 further includes an acceleration sensor 2210. The window breaker control unit 2201 includes an electrical initiation window breaker 2203, and the electrical initiation window breaker 2203 may be a window breaking switch.
The central control unit 210 controls the WBCU of each carriage by using the field bus 230 in the train, to avoid any unnecessary and unexpected window breaking action.
The central control unit 210 is further connected to a manual control switch 211 disposed in a central control room of the train, and may be started by a train driver by pressing a single button in the central control room, so as to break all glass of the entire train in an emergency. The system must be controlled by the train driver in a centralized manner, to avoid any unexpected or unnecessary window breaking action.
The central control unit 210 receives a signal from the detection unit 2204 of the WBCU of each carriage. That is, the central control unit 210 monitors, in a centralized manner, the smoke concentration and temperature of each carriage, and/or field images collected by the photographing apparatus 2206, and the WBCU of each carriage cyclically sends temperature, smoke, and photographing information to the central control unit 210. The central control unit 210 processes the information from each carriage, detects which carriage's window needs to be broken, and sends a window breaking request to a glass breaker control unit 2201 of the corresponding carriage, and a corresponding electrical initiation window breaker 2203 executes a window breaking action according to the received request.
Further, the window breaking system shown in FIG. 2 further includes a speed detection apparatus 242 connected to the engine control unit 240. A combination of the speed detection apparatus 242 and the engine control unit 240, for example, may be referred to as a dynamical system, so as to control the window breaking system to be linked with a train speed. The speed detection apparatus 242 is one or more of various speed sensors, for example, a wheel speed sensor. The speed detection apparatus 242 regularly detects the train speed when the central control unit 210 determines that a window needs to be broken by explosion, and data detected by the speed detection apparatus 242 is sent to the central control unit 210 by using the engine control unit 240. If the detected train speed is greater than a particular value, for example, 10 km/h or 20 km/h, the central control unit 210 sends an instruction to the brake control unit 250 to start braking to reduce the train speed, and the central control unit 210 does not send an explosion execution instruction to a glass breaker control unit 2201 of a carriage whose window needs to be exploded until the speed detection apparatus 242 detects that the train speed is less than the particular value.
In addition, when operating the manual control switch 211, a driver may not consider a determining result of the central control unit 210, and directly control working of the glass breaker control unit 2201 by using the manual control switch 211. That is, the window breaking system of the present invention includes two working modes: an automatic mode and a manual mode. In the automatic mode, the algorithm control and drive circuit 212 of the central control unit 210 determines, according to the received acceleration, temperature, smoke, and/or photographing signal from the detection unit 2202, whether an explosion condition is met, without a need of operating the manual control switch 211, or in the automatic mode, the manual control switch 211 may be omitted. In the manual mode, the driver determines whether an explosion condition is met and directly operates the manual control switch 211. This mode is a second-choice mode used as a supplement of the automatic mode. The driver may start, according to a situation and when a window needs to be broken by explosion, the manual control switch 211 to execute an explosion action.
When generating and executing a window breaking instruction, the central control unit
210 detects train speed information sent by the engine control unit 240 on a train carriage network. When the train speed is less than a preset limited train speed (for example, 10 km/h), the window breaking instruction may be executed. When the train speed is greater than a preset limited train speed (for example, 10 km/h), the central control unit 210 sends an instruction to stop the engine, and start the brake control unit 250. Meanwhile, the window breaking instruction is locked, and the train speed is detected at an interval, such as every 100 ms. When the train speed is less than the limited train speed, window breaking is executed.
In a preferred embodiment, the electrical initiation window breaker 2203 of each carriage includes multiple glass explosion devices (not shown in the figure), and the multiple glass explosion devices are installed at different positions on a same piece of window glass, or the multiple glass explosion devices are respectively installed on different pieces of window glass.
It may be understood that the window breaking system of the present invention may be applied to both a conventional train and a subway. The present invention may also be applied to a fire safety system of a building, especially a modem building with a large quantity of glass walls, so as to provide more escape paths when a disaster happens. When the window breaking system of the present invention is applied to fire safety of a building, the carriage may be understood as different units of the building, such as a room, or a unit with particular space.
The foregoing descriptions are merely preferable embodiments of the present invention, and are not intended to limit the present invention. For a person skilled in the art, various modifications and variations may be made to the present invention. Any modification, equivalent replacement, and improvement made without departing from the spirit and principle of the present invention shall fall within the protection scope of the present invention.
