Description

[0001] SECONDARY ACCIDENT PREVENTION SYSTEM FOR HAZARDOUS MATERIAL TRANSPORTATION VEHICLES [0002]

More particularly, the present invention relates to a second accident prevention system for a vehicle, and more particularly, to a vehicle accident prevention system capable of promptly operating in the event of an accident, And a second accident prevention system of a dangerous goods transportation vehicle capable of generating data necessary for preparing countermeasures.

In recent years, with the expansion of roads, the opening and the increase of logistics, the rate of accidents of freight vehicles is increasing each year as the transportation industry is activated and the number of vehicles is increasing. In particular, accidents involving cargo vehicles carrying hazardous materials such as toxic materials, wastes, oil, and gas are secondarily damaging to the human body and ecosystem as well as massive physical damage.

In the past, techniques have been proposed that can manage the location, arrival, departure time, and traveling speed of a transportation vehicle by utilizing a GPS and its associated system. However, in the case of an accident, After receipt of the accident, it was determined that the types of dangerous materials, the amount of load, the amount of leakage, etc., were taken into consideration, and measures and measures were taken to prevent the spread of secondary damage.

Especially, there is a risk that other vehicles that do not recognize when a flammable or explosive dangerous goods transport vehicle is overturned or a fire occurs may lead to a series of accidents such as entering into an accident area or failing to evacuate people. No separate management has been done at all when passing through dangerous areas such as drugs and oil refineries or near gas stations.

In addition, when an accident occurs, the agency responsible for the accident area has its own response to the accident, so information exchange is not active. In addition, if the death of an accidental person or the loss of a car is not precisely understood There is a problem in that a comprehensive measure such as a recurrence of the same type of accident is not smoothly made.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a configuration of a secondary accident prevention system of a dangerous goods vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a conceptual diagram of the present invention. FIG. 2 is a block diagram illustrating a configuration and a connection relationship according to a first embodiment of the present invention. The present invention is basically installed in a dangerous goods vehicle 100 designated as a monitoring target So that individual communication with the remote control server 200 can be performed through the unique ID assigned to the vehicle.

In addition, the present invention basically allows a plurality of target vehicles 100 to be managed in real time, and the management server 200 includes a control room of a fire station where an immediate response can be made when an accident situation is detected, And to be placed in a government office that can respond. In addition, the present invention can be applied not only after completion of the production of the vehicle, but also in a dangerous goods transportation vehicle that is currently in operation as well as a new vehicle to be newly installed.

First, in the first embodiment of the present invention, the structure to be installed in the monitored vehicle 100 includes an impact detection unit 111, a rollover detection unit 112, a position measurement unit 113, A first communication unit 130, a fire evacuation unit 120, an alarm unit 140, and a first control unit 180 are provided.

The impact sensing unit 111 is a sensor that senses an impact applied to the vehicle 100 and can be implemented using an acceleration sensor capable of sensing a momentary change in force. In the event of a collision accident, So that it is preferable to be provided on the outer side of the vehicle. In addition, due to the nature of a dangerous goods transporting vehicle such as a tank lorry, the impact generated from one side may not be smoothly transmitted to the other due to the size of the vehicle and the link structure. Therefore, It is preferable that the bumper and the side surface of the motor are dispersedly installed.

The rollover detecting unit 112 is a tilt sensor for detecting the inclination of the vehicle, and can be realized through a gyroscope sensor capable of detecting a change in angle, thereby determining whether the vehicle is rolled over. Since the collision of a vehicle does not necessarily lead to the overturning of the vehicle, it is important to judge whether or not the vehicle is rolled up in order to prevent secondary accidents. Especially, in case of a dangerous vehicle, It is more likely to cause serious secondary damage such as additional human casualties, environmental pollution, etc. Therefore, it is necessary to take quick action and take countermeasures.

In this case, in the case of a large-sized tanker-carrying structure, the driving unit and the cargo loading unit are often linked by a link structure like a trailer. Secondary damage to the car overturn is high at the cargo loading unit side, Is preferably provided on the side of the cargo loading section.

In addition, the rollover detection unit 112 may be configured to use two or more sensors that respectively detect the tilt of the vehicle in the front-rear direction and the tilt of the vehicle in the lateral direction so as to enable accurate detection of the rollover type.

The position measuring unit 113 calculates the position and speed of the vehicle as a GPS receiver.

The first fire detection unit 114 is configured to detect a fire caused by an accident. In case of a material having explosive or flammable materials, if the fire does not evolve in a very short time, At the time of arrival, most of the cases can not be practically practiced.

The first fire detection unit 114 is composed of a plurality of sensors capable of detecting a fire, and is installed in an engine room, a fuel system, and a relatively vulnerable portion of the cargo loading unit. In this case, the sensor capable of detecting a fire can be a sensor capable of detecting a flame, a heat or a gas due to a fire. Preferably, a sensor capable of detecting heat or carbon monoxide or a combination of both can be used.

The fire evacuation unit 120 includes a fire extinguishing tank 121 in which a gas type fire extinguishing agent such as CO2 is compressed and injected and a plurality of nozzles 122 for spraying the fire extinguishing agent stored in the fire extinguishing tank 121 . At this time, the nozzle 122 is controlled to be opened and closed by a first control unit 180, which will be described later. Like the sensor installation place of the first fire sensing unit 114, the relatively weak portion of the engine room, the fuel system, So that the nozzles 122 installed in the part where the fire is detected can be individually opened.

The first communication unit 130 may be configured to transmit and receive data using a commercial mobile communication network as a wireless communication module. Data transmission and reception can be performed with the portable server 200, .

The alarm unit 140 is configured to output an alarm signal to the driver of the vehicle using a visual or audible signal, and may be configured through simple display means including a buzzer and a beacon. At this time, the alarm signal may be a signal generated from the boarding vehicle or a signal transmitted from the control server 200.

The first controller 180 receives the power and receives the shock detection unit 111, the rollover detection unit 112, the position measurement unit 113, the first fire detection unit 114, the fire evolution unit 120, The detection result of the impact detection unit 111, the rollover detection unit 112 and the first fire detection unit 114 is temporarily stored in the first communication unit 130 and the alarm unit 140, And a judgment unit 181 for judging the situation.

That is, the determination unit 181 determines that a collision accident occurs when an impact equal to or higher than a predetermined level is detected through the impact sensing unit 111. As described above, when a plurality of impact sensors are provided, Part is also judged and stored temporarily.

If the angle change detected by the rollover detection unit 112 is equal to or higher than the predetermined level, the determination unit 181 determines that the vehicle is overturned. The fire detection location is judged and stored temporarily to recognize a comprehensive accident situation.

In addition, the first controller 180 controls the fire evacuation unit 120 according to the determination result of the determination unit 181 to open the nozzle 122 installed at the position where the fire has occurred, In this case, the driver is notified of the accident situation through the alarm unit 140, and the operation status of the fire position and the fire evacuation unit 120 is monitored through the display unit provided in the alarm unit 140 .

In addition, the first control unit 180 transmits the calculation result of the position measuring unit 113 and the determination result of the determination unit 181 to the management server 200 through the first communication unit 130, The calculation result of the position measurement unit 113 and the determination result of the determination unit 181 are transmitted periodically or in real time even if there is no accident occurrence. This will allow the management organization to monitor the operation status of the dangerous goods transport vehicle.

At this time, the power supplied to the first control unit 180 is supplied through a separate power source unit P made of a lithium battery, and power is supplied together with charging through a power source generated from the vehicle, Power can be supplied through the power source unit P in a disconnected state.

The control server 200 is configured to collect signals transmitted from a plurality of monitored vehicles and to monitor them in real time at a management institution. The control server 200 includes a second communication unit 210, a database 220, 230, a level setting unit 240, an identification unit 250, and a second control unit 260.

The second communication unit 210 is the same wireless communication module as the first communication unit 130, and data transmission / reception can be performed through communication with each monitored vehicle.

The database 220 stores pre-inputted vehicle information, dangerous area information, and map information. At this time, the vehicle information includes information including the ID of the monitored vehicle, the affiliation of the vehicle, the vehicle's specification and the vehicle number, as well as the transportation material currently loaded, the loading amount, the departure place and the destination, The information from the shippers of the load is reported and stored beforehand. In addition, the dangerous area information includes information such as the location of a gasoline station or a gas filling station, as well as an area where a second major accident is likely to occur, such as a petroleum industrial complex or a chemical industrial complex. .

The monitoring unit 230 collects the position and speed information transmitted from the monitored vehicle and outputs the information together with the map information. In the organization where the control server 200 is located, the ID of the vehicle is displayed on the map It is preferable that output is performed so that vehicle information including the speed can be read.

The level setting unit 240 is configured to set the speed of the monitored vehicle and the alert level for entry into the operating area. The level setting unit 240 determines whether the speed of the monitored vehicle is overspeed, ), And the level at which an alarm will be triggered for conditions such as overspeed occurrence within the operating area.

The identification unit 250 identifies a monitored vehicle that is to be entered into an accident situation occurrence area. If an accident occurs in a monitored vehicle and the other vehicle is entered without being able to respond inevitably, it may be more likely to cause an accident. .

To this end, the identification unit 250 searches for vehicle information about another monitored vehicle and a nearby vehicle located in an area where an accident has occurred in the monitored vehicle, enters the accident occurrence area, or enters the service area The vehicle is identified in advance.

The second control unit 260 controls the second communication unit 210, the database 220, the monitoring unit 230, the level setting unit 240, and the identification unit 250. The level setting unit 240 to the target vehicle via the second communication unit 210 with respect to the monitored vehicle identified by the identification unit 250 or the monitored vehicle having the specified ID.

FIG. 3 is a block diagram illustrating a configuration and a connection relationship according to a second embodiment of the present invention. In the first embodiment of the present invention described above, an input unit 150, which is a configuration for relieving a driver when an accident occurs, A fire detection unit 115, a leak detection unit 116, and an oxygen supply unit 160 are added. In the following description, the same components as those in the first embodiment described above will not be described in detail.

The input unit 150 is configured to receive an accident situation from a driver, and is preferably constructed of a switch having a relatively simple structure for quick operation in emergency situations. This is because it is not possible to detect an accident through the impact detecting unit 111 or a situation where the overturning state is not determined through the rollover detecting unit 112, Unexpected danger may occur even under unusual circumstances that are not judged to be a fire, and when a normal accident judgment is not made due to mechanical or electronic error, So as to inform the control server 200 of the accident situation.

The second fire sensing part 115 is the same as the first fire sensing part 114 in that it is configured to detect the occurrence of a fire. However, the second fire sensing part 115 may include a first fire sensing part A fire in the driver's seat is detected separately from the driver's seat 114.

The leakage detection unit 116 is a sensor for detecting the leakage of the dangerous goods loaded on the monitoring target vehicle, and a sensor suitable for detecting dangerous materials normally loaded on the vehicle is applied. When a load is a liquid, a liquid detection sensor capable of detecting the load is used, and if the load is volatile or gas form, it can be implemented using a gas detector.

The oxygen supply unit 160 is installed in a driver's seat of a vehicle to supply oxygen to a driver in an emergency. The oxygen supply unit 160 may be configured to assist a driver in safely escaping when a load that may cause fatal breathing is leaked or a toxic gas is generated Or to protect the driver's life in situations where he or she is awaiting relief. At this time, it is possible to use a natural discharge system that releases oxygen to the inside of the driver's seat, or an oxygen mask connected to the oxygen tank is supplied in a stored state and oxygen can be opened. However, when oxygen is emitted into the driver's seat in the driver's seat, the damage caused by the fire can be increased. Therefore, when the spontaneous emission system is applied, a fire occurs in the driver's seat through the second fire sensing unit 115 It is necessary to configure it to operate in the confirmed state.

The first control unit 180 controls the oxygen supply unit 160 according to the detection result of the second fire sensing unit 115 and outputs information input through the input unit 150 and the second fire sensing unit 115 and the leakage detection unit 116 to the control server 200 through the first communication unit 130 so that the organization where the control server 200 is located is preferentially associated with the structure of the person's name Ensure that prompt action is taken against cargo leaks.

FIG. 4 is a schematic diagram showing a structure for detecting and evacuating fire and leakage, and shows a representative example of the arrangement of the impact detection unit 111, the first fire sensing unit 114, and the fire evacuation unit 120.

As shown in FIG. 4, the impact sensing unit 111 is installed near the front and rear bumpers of the vehicle and the side of the vehicle, respectively. The impact sensing unit 111 senses an impact, (111) can be provided.

In the case of the first fire detection unit 114, the engine room, particularly the fuel system, which is likely to cause fire in the event of an accident, will be the main installation position. In the cargo loading unit 114, The fire evacuation unit 120 may be selectively installed at a position where the first fire sensing unit 114 is likely to generate a fire, .

FIG. 5 is a block diagram illustrating a configuration and a connection relationship according to a third embodiment of the present invention. The flow sensing unit 170 is a constitution that can more accurately grasp the outflow situation of a hazardous material loaded on a vehicle and cope with it, A calculation unit 182 is added.

FIG. 6 is a conceptual diagram showing a flow sensing structure according to a third embodiment of the present invention. FIG. 6 (a) shows a state of a normal horizontal state, and FIG. 6 (b) shows a state of an inclined state. The flow sensing unit 170 has a floating body 171 which is positioned in the loading part and drifts in a vertical state on the surface of the load. By measuring a distance change with the upper side wall of the loading part, The degree of leakage can be roughly calculated, but the operation is performed after the determination of the occurrence of the accident is made through the determination unit 181. [

The floating body 171 is made of a material having chemical resistance and explosion resistance. The floating body 171 is basically made to float on the liquid surface at all times, and the center weight 172 is embedded in the lower part thereof. .

A distance measuring unit 173 measures the distance from the inner wall of the cargo carrying unit located on the upper side by applying a laser to the floating body 171 to measure the distance by receiving the reflected laser beam, And a third communication unit 174 for transmitting the calculation result of the distance measuring unit 173 to the first control unit 180. The third communication unit 174 may be connected to the first control unit 180 directly via a cable or the like, or may include a separate communication relay device for relaying data communication between the inside and outside of the loading unit. The calculation result of the first communication unit 173 may be transmitted to the first control unit 180 by wireless communication with the first communication unit 130. [

At this time, the first controller 180 controls the amount of the cargo loading amount based on the stored cargo loading amount, the size information of the cargo loading unit, the slope sensed through the rollover sensing unit 112, and the result transmitted through the flow rate sensing unit 170 And a flow rate calculating section 182 for calculating the change.

That is, the initial loading amount, the slope of the cargo loading portion measured through the rollover sensing portion 112, and the distance measured through the distance measuring portion 173 are set as initial values, Although it is difficult to calculate a substantially accurate leakage amount by calculating the variation value of the distance measured through the distance measuring unit 173, it is possible to roughly calculate the leakage speed including the leakage when the leakage of the load occurs, 1 communication unit 130 to the control server 200 so as to prompt a quick response through the determination of the leak rate and the leak rate.

In addition, it is necessary to shut off the fuel supply to the fuel system for rapid extinguishment in case of fire in the fuel system of the vehicle. And a fuel cutoff unit 190 installed in the fuel system of the vehicle and configured to shut off the fuel system according to the detection result of the first fire detection unit 114. The fuel cutoff unit 190 includes a fuel cut- A quick-closing valve that can be instantly closed by inputting or interrupting a driving signal while maintaining a normally open state can be used.

Since the first communication unit 130 and the first control unit 180 of the present invention are important components for propagating the situation through communication with the control server 200, smooth operation can not be guaranteed in case of damage, And it is preferable to be protected through a package which is durable and does not break even under fire or chemicals for a certain period of time.

It is to be understood that the invention is not limited to the disclosed embodiments, but is capable of many modifications and variations within the scope of the appended claims. It is self-evident.
