Description

[0001] Remote management system for tunnel [0002]

The present invention relates to a remote tunnel management system. More specifically, the present invention relates to a remote tunnel management system that efficiently monitors and manages the operation state of each of traffic equipments installed in a tunnel remotely and outputs an emergency broadcast in response to traffic conditions in a tunnel, To a remote tunnel management system capable of enhancing the audibility of an emergency broadcast.

As the transportation infrastructure is expanded and the electronic device technology is developed, a variety of traffic equipments such as speakers, electric signboards, CCTV cameras, signal systems and detection sensors are installed all over the roads.

As the number of vehicles increases and the roads expand, the number of tunnels for connecting roads, railways, and waterways has also increased. Such tunnels can be easily connected without bypassing the difficult roads, Thereby saving time and enhancing mobility and convenience of the vehicle.

However, since the tunnels are characterized by the fact that the four sides are closed except for the entrance road and the entrance road, the visibility of the driver is remarkably lower than that of the open road, so that the traffic accident frequently occurs. In addition, The fire suppression and lifesaving are difficult, and the toxic gas is not discharged to the outside, so that it is likely to be an accident.

Especially in recent years, Intelligent Transport System (ITS) has been introduced to analyze traffic situation in real time by sensing various kinds of information on roads and processing traffic information on the basis of it. As a result, ITS is also equipped with a variety of traffic equipments such as an emergency broadcasting speaker, an electric signboard, various sensors, a camera, an air conditioner, LED, and the like in a tunnel, an entrance road and an entrance road.

Such a traffic equipment has trouble due to various causes such as computation throughput, driving time, communication load and environmental conditions. Such a failure not only prevents the function of the corresponding equipment from being performed, but also leads to a traffic accident, How quickly it responds is a very important issue that can be directly linked to a safety accident.

However, in the past, when a fault occurs in any one of the tunnel traffic equipments, a worker having a knowledge of the equipment visits the site directly to recover the fault, but in general, Failures caused by transient loads are the most important part, and failures due to such temporary loads have characteristics that can be restored by rebooting (resetting) the relevant equipment.

Therefore, even if a worker visits the site in the event of a failure, the trouble is often restored only by rebooting the corresponding equipment. Therefore, labor and time are wasted, the efficiency of equipment inspection and operation is poor, Given the nature of the traffic equipment, there is a structural limit to delaying the time to deal with the obstacle.

On the other hand, since the tunnel has a higher incidence of traffic accidents than ordinary roads, it also leads to large-scale casualties and high mortality rates in the event of an accident, so information on emergency situations such as traffic accidents and congestion in tunnels is displayed to drivers in the tunnel Various studies have been made on a tunnel broadcasting system for preventing a traffic accident in a tunnel in advance.

A tunnel internal emergency broadcasting system (hereinafter referred to as " prior art ") for outputting an emergency broadcast is disclosed in Korean Patent No. 10-1178879 (entitled " Upon receipt of the FM signal including the broadcast signal, the emergency broadcast signal of the received FM signal is changed to an audible frequency boundary band and outputted to the outside so that the driver can quickly recognize the emergency situation.

However, since the tunnel has a feature that the inner space is sealed, when the emergency broadcast is output from the inside of the tunnel, the output sound wave is reflected on the inner wall of the tunnel, and the time difference of the sound wave and the original sound is generated, There are structural limitations in that the phenomenon is excessively made and the audibility is very poor. Especially, in case of the driver of the vehicle, even if the emergency broadcasting is outputted in the tunnel due to the vehicle noise, the emergency broadcasting can not be heard accurately.

That is, as described above, the conventional art does not consider the tunnel structure forming the closed space at all, and since a plurality of speakers are installed in the tunnel, the time difference with the original sound and the interference phenomenon of the sound waves excessively increase, Even if an emergency broadcast is outputted, the vehicle driver has a structural limitation that it can not correctly listen to the emergency broadcast, and the inherent function of outputting the emergency broadcast is lost due to the limit.

At this time, a plurality of loudspeakers are installed in the inside of the tunnel to output emergency broadcasts. These loudspeakers are installed in a small number in comparison with the length of the inside of the tunnel, or when the spacing between adjacent loudspeakers is excessively spaced, On the contrary, when an excessively large number of speakers are installed, the audibility is deteriorated due to echo of the sound wave. That is, even if emergency broadcasts are output from the speakers of the same quantity and position, the audibility varies depending on various requirements such as the vehicle occupancy rate in the tunnel, the number of vehicles (N), and the vehicle speed.

However, the prior art does not consider the characteristics of broadcasting in the tunnel at all, so that emergency broadcasts are outputted simultaneously from all the speakers when an emergency broadcast is generated, so that the information is not efficiently transmitted due to the low audibility.

Also, in the conventional art, since output is performed in all of the speakers during emergency broadcasting, the equipment is frequently broken down, checked and replaced frequently, which increases the operating cost.

As a method for solving the problem of low audibility due to the echo in the tunnel, a system has been studied in which an emergency broadcast is transmitted through a wireless communication network to a portable terminal (smart phone, etc.) of a driver of a vehicle, It is necessary to separately establish a wireless communication network that can be supported by the portable terminal in the tunnel and to install the application separately in the portable terminal in order to output the broadcast received by the portable terminal, .

In other words, it is possible to efficiently monitor and manage the tunnel traffic equipments 1) remotely and at the same time, 2) to cope with the obstacles in case of traffic equipment failure, and 3) There is an urgent need for a tunnel management system capable of outputting data.

4 is an exemplary view for explaining the loudspeakers of the present invention.

As shown in FIG. 4, the speakers 53 are spaced apart from each other on the inner wall of the tunnel 20. At this time, the installation interval of the speakers 53 may vary depending on the road environment, the average occupancy rate, etc., but is preferably about 50 m.

The speaker 53 outputs the emergency broadcasting according to the control of the connected IOT equipment 4. When the IOT equipment 4 receives the emergency broadcasting sound data from the controller 3, And outputs the received emergency broadcasting sound data.

At this time, the emergency broadcast includes accident information, road freezing information, slip information, congestion information, and the like.

The configuration of such a speaker is not limited to this, and it is of course possible to further include basic configurations of a normal speaker.

In addition, according to the control of the controller 3 during the emergency broadcast output, only the speakers selected according to traffic conditions in the current tunnel output emergency broadcasts, thereby maximizing the audibility.

The cameras 54 are installed so as to be spaced apart from each other in the tunnel to perform imaging, and transmit the acquired images to the controller 3.

At this time, the images photographed by the cameras 54 are analyzed by the controller 3 and used for generating traffic information in the tunnel.

The pollution degree sensor 57 is installed inside the tunnel 20 to detect air pollution degree, and transmits the detected pollution degree information to the controller 3.

That is, the controller 3 compares the pollution degree received from the pollution degree sensor 57 with a predetermined threshold value. If the pollution degree exceeds the threshold value, the controller 3 determines that ventilation is necessary and drives the ventilation device 55, 55), the ventilation devices 55 are rotated and driven according to the wind direction information detected by the wind direction / wind speed sensor 56, so that ventilation efficiency can be improved and ventilation can be performed quickly.

1 and 2, the communication network 10 provides a data movement path between the controller 3, the control center server 7, and the administrator terminal 9, and more specifically, a wide area network (WAN) Communication network, wired communication network, LTE, and the like.

The local area network 11 provides a data movement path between the IOT equipment 4 and the controller 3. More specifically, the local area network 11 includes a wired communication network such as an RS232C cable and a LAN cable, a Zig- (Blue-tooth), Wi-Fi (Wi-Fi), and the like.

The IOT devices 4 are connected to the traffic equipments 5-1, ..., and 5-N, respectively, and control power supply to the connected traffic equipments.

Also, the IOT equipment 4 is connected to the controller 3 and the local area network 11 to form a network with each other. At this time, the network can be implemented as a master-slave system in which the controller 3 is set as a master and the IOT equipment 4 is set as a slave, thereby improving the processing efficiency.

In addition, the IOT equipment (4) is manufactured in a module form so that connection and interworking with the traffic equipment (5) can be performed easily.

Also, the IOT equipment 4 detects the consumption current by disposing a current sensor at a relay output that supplies power to the connected traffic equipment 5.

The IOT equipment 4 also detects input / output data of the connected field equipment.

The IOT equipment 4 performs a known ping-test (hereinafter referred to as a first ping test) every predetermined period (T) according to the control of the controller 3, .

The IOT equipment 4 also transmits the detected power data, input / output data, and first ping-data to the controller 3 via the local area network 10.

When the IOT equipment 4 receives the reset command data from the controller 3, the IOT equipment 4 resets the corresponding traffic equipment and itself.

The controller 3 manages and controls the IOT equipment 4.

The controller 3 also analyzes the loop signal received from the first loop detector 51 and the second loop detector 52 and detects the quantity N of the vehicles passing through the tunnel 20.

The controller 3 also analyzes the photographed image transmitted from the cameras 54 to detect vehicle occupancy rate, vehicle speed, congestion rate, and accident occurrence information. At this time, the accident occurrence information indicates whether or not a traffic accident occurred.

The controller 3 also generates traffic information in the tunnel including the detected vehicle quantity N, occupancy rate, vehicle speed, congestion ratio, accident occurrence information, etc., and transmits the generated traffic information in the tunnel to the control center server 7 Lt; / RTI >

The controller 3 is also connected to the control center server 7 via the communication network 10 and receives the emergency broadcast sound data from the control center server 7. [

The controller 3 is connected to the IOT equipment 4 of the speakers 53 of the traffic equipments 5 by the local area network 11 and the emergency broadcast sound data received from the control center server 7 is transmitted to the speaker 53. [ And transmits the received emergency broadcasting sound data to the IOT equipment 4 so as to be outputted through the IOT equipment 4.

At this time, when the controller 3 receives the emergency broadcasting sound data from the control center server 7, the controller 3 outputs the emergency broadcasting sound data, which is a speaker for outputting the emergency broadcasting among the speakers 53 on the basis of the traffic information in the tunnel, And transmits the emergency broadcasting sound data to the speakers 53 determined as the output objects, thereby maximizing the audibility in response to the current traffic situation in the tunnel.

For example, if the occupancy rate of the traveling vehicle in the tunnel is less than 10%, the controller 3 determines that the number of the output targets is a few, so that the emergency broadcasting is outputted only in a small number of speakers. If the occupancy rate of the traveling vehicle in the tunnel is 70% It is possible to configure the output destination to be a plurality of output destinations and to output emergency broadcasts from a plurality of speakers. The output destination determination method and technique of the controller 3 will be described later in detail with reference to FIGS. 6 to 8 .

The controller 3 periodically receives power data, input / output data, and first ping-data from each IOT equipment 4, analyzes and processes the received data, and determines the power state, the communication state, the input / And generates operation state information.

In addition, the controller 3 analyzes the generated operation state information using a predetermined failure detection algorithm to determine whether or not the failure has occurred. For example, the failure detection algorithm may be configured to detect a failure according to whether or not the power state, the communication state, and the input / output states are compared with each of the predetermined thresholds and out of the threshold, The determination method is not limited thereto, and various methods and techniques can be applied.

Further, the controller 3 performs a second ping-test for detecting its own communication state every predetermined period (T).

At this time, the controller 3 analyzes the first ping-data (by the first ping-test) received from the IOT equipment 4 and, if a communication failure of the corresponding IOT equipment is detected, (2) by analyzing the second ping-data by the second ping-test to detect a communication failure, it is possible not only to check the communication state of the controller 3 itself by resetting itself, The communication status can be doubly checked.

In addition, the controller 3 transmits the generated operation state information to the control center server 7, and if it is determined that a failure has been detected, it transmits 'failure occurrence confirmation data' to the control center server 7 indicating that a failure has occurred .

The controller 3 also sends reset command data to the IOT equipment 4 to reset (reboot) the corresponding IOT equipment 4 and the traffic equipment 5 if it is determined that a fault has occurred in the particular IOT equipment 4, And judges whether the fault has been solved or the fault is continued through the operation state information of the rebooted IOT equipment.

At this time, if it is determined that the failure is continued, the controller 3 transmits the failure persistence confirmation data to the control center server 7.

The controller 3 also compares the pollution degree measurement value p received from the pollution degree sensor 57 with a predetermined threshold value and if the pollution degree measurement value P is below the threshold value it is not necessary to drive the ventilation device 55 And judges that the ventilation device 55 needs to be driven if the pollution degree measurement value P exceeds the threshold value.

When it is determined that the ventilation device 55 needs to be driven, the controller 3 also uses the wind direction / wind speed data received from the wind direction / wind speed sensors 56 to determine the arrangement of the wind direction generated in the ventilation device 55 And if the two directions coincide, transmits the drive control data to the IOT equipment 4 of the ventilator 55. If the two directions do not coincide, the ventilator 55 transmits the drive control data to the IOT equipment 4, And transmits driving control data when the rotation of the ventilator 55 is completed.

At this time, the IOT equipment 4 of the ventilator 55 drives the rotating blades of the ventilator 55 if it receives the driving control data from the controller 3, and if it receives the rotation control data, And controls the pivoting means so that when the ventilator 55 is viewed in a plan view, it is rotated 180 degrees from the current direction.

That is, according to the present invention, the air inside the tunnel can be efficiently and quickly ventilated by generating the wind force after rotating the ventilator 55 according to whether the wind direction inside the tunnel is '+ X' or '-X'.

The control center server 7 is a server of the control center that manages and controls the controller 3 and monitors the operation status of each IOT equipment 4 transmitted from the controller 3. [

That is, the control center server 7 processes the operation state information received from the controller 3 and displays it on a display device such as a monitor, thereby enabling monitoring by the administrator.

In addition, the control center server 7 analyzes the operation state information received from the controller 3 to re-determine whether or not a fault has occurred. In the present invention, the controller 3 and the control center server 7 double- do.

If it is determined that a failure has occurred, the control center server 7 transmits 'failure occurrence confirmation data' indicating that a failure has occurred to the controller 3. At this time, when the controller 3 receives the failure occurrence confirmation data from the control center server, the controller 3 compares whether or not it has determined that a failure has occurred itself before the critical range from the point of time of transmission, and if the failure occurs in itself between the reception time and the critical range If it is determined that the failure has not occurred, a reset operation (reboot) is performed.

That is, when it is assumed that the control center server 7 and the controller 3 operate normally, the same determination result as to whether or not a fault has occurred is detected from the same operation state information. However, when the controller 3 detects a fault It is determined that a failure has occurred only in the control center server 7.
