Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information collecting system for improving bus and road environment,

The present invention relates to a method for collecting data for the purpose of improving the flow of public transportation and the convenience of passengers to improve the environment of bus users, The present invention relates to an environmental collection system and method for improving the bus and road environment.

Buses are a means of transportation for the purpose of transporting many people, and drivers are arranged for each bus. Buses in the city center stop at regular intervals and stop at regular intervals to get on or off the passengers.

Buses can accommodate as many as 300 passengers, making them one of the most important means of improving urban functioning, especially as a key means of transport for urban dwellers. The smooth operation of buses is essential to improve city functions and improve the mobility of urban people.

In order to operate the bus smoothly, it is necessary to secure the basic moving speed of the bus on the public road, such as the domestic road, and to adjust the dispatch interval so that the number of passengers to be used per bus is not exceeded There is a need.

Intermission

On the road, a prohibited area prohibiting the driving of the driving vehicle is set for the smooth progress of the vehicle, and the vehicle which is parked in the prohibited driving area is subject to the control.

In order to control a vehicle parked in the forbidden zone, evidence is required that the vehicle has been parked for more than a certain period of time in the prohibited parking zone. For this, a member of the police officer takes a picture of the vehicle and records it. At first, parking officers took pictures of illegally parked cars while moving directly. Recently, camera systems have been developed and installed to monitor the entire prohibited area according to the development of cameras and image processing technology.

In particular, FIG. 1 shows a driving-type intermission system for photographing a vehicle parked in a parked area using a camera mounted while the vehicle is traveling in the parked area. This method is advantageous in that it is easy to shoot the license plate, so that the license number recognition rate is high and the license plate of the vehicle located at the square is comparatively easily taken. Korean Utility Model Registration No. 416652 and the like are examples of the traveling type interception system.

1, there is shown a vehicle 10 that moves along a prohibited area x and a camera 11 is mounted on the vehicle 10. The camera 11 is mainly a vehicle 10) and uses a 'pan / tilt zoom camera' that can be pan tilted and zoomed.

The speedometer vehicle 10 moves along the prohibited area x and sets the zoom and pan / tilt angles of the camera 11 to photograph the license plate of the vehicle m. It is general that the pseudo range-prohibited area x is shaped into a rectangular area, so that the camera 11 installed on the vehicle 12 is also set to a fixed angle and a focal distance.

Alternatively, Korean Patent Registration No. 0970495 discloses a system in which a sensor is installed in a bus bay to notify a driver that an illegal driving license is entered when a vehicle is entered, rather than a bus, and an illegal driving car is photographed using a camera.

Collection of bus information

Information for understanding the bus usage environment may include passengers in real-time riding or getting off the bus, bus temperature, humidity and fine dust concentration. Conventionally, a bus system for collecting such bus environment information has not been developed or known. For example, it can not but be confirmed by using CCTV installed on a bus.

Items necessary for the operation of the management server 130 will be described below again.

Bus system

The bus system 110 is a device installed in a running bus 10 and connected to the management server 130 through a network 150. [ 2 and 3, the bus system 110 includes a sensor unit 111, a GPS receiver 113, a camera unit 115, a phased array sensor unit 117, and a controller 119.

The sensor unit 111 is installed in the bus 10 and measures temperature / humidity and fine dust concentration inside the bus and provides the measured temperature / humidity and fine dust concentration to the controller 119. The sensor unit 111 includes a temperature and humidity sensor 111a and a fine dust sensor 111b . The fine dust sensor 111b periodically measures the dust concentration in the bus and provides it to the controller 119. [

The GPS receiver 113 receives and processes the signals provided by the GPS satellites to generate current position information of the bus 10 and provides the current position information to the controller 119.

The camera unit 115 is provided inside the front windshield 10c of the bus 10 and photographs the vehicle that has been parked on the road ahead of the bus under the control of the controller 119 and provides the captured image to the controller 119. The camera unit 115 may be an IP camera capable of not only storing a certain amount of images with its own memory but also accessing an IP network. The image is transmitted to the first server 131 through the controller 119 even in the case of the IP camera.

The phased array sensor unit 117 includes at least one phased array sensor 117a and 117b provided on one side of a boarding gate 10a and a down gate 10b of the bus 10 or a boarding step of the gate thereof The boarding gate 10a and the getting-off gate 10b, or the passenger located on the boarding stairs of the gate.

The phased array sensors 117a and 117b radiate a beam of a plurality of channels (for example, 16 channels or 32 channels) forward along one virtual plane, then receive a beam reflected from an object ahead, (LIDAR) sensor, and the like. The phased array sensor unit 117 constitutes a passenger counter together with the passenger recognition unit 205 of the controller 119 described below and the passenger recognition unit 205 compares the measured value of the phased array sensor unit 117 Can be used to count the number of passengers boarding or departing at the boarding area. The method of installing the phased array sensor unit 117 and the like will be described below again.

The controller 119 controls the overall operation of the bus system 110 and includes a wireless communication interface 201, a constant distance intermittent portion 203, a passenger recognizing portion 205, and an information collecting portion 207 and operates with the power provided by the bus 10.

The wireless communication interface 201 wirelessly connects the bus system 110 to the management server 130 via the network 150. The wireless communication interface 201 provides the first server 131 or the second server 133 with various data or images generated by the intermittent intermittent portion 203 of the controller 119 or the information collection unit 207.

The parking lot intermittent portion 203 provides the first server 131 with the image of the vehicle photographed by the camera portion 115 while passing through the illegal parking intermittent area on the basis of the location information provided by the GPS receiver 113, Allow the process to proceed.

The parking lot intermittent speed control unit 203 checks the illegal parking intermittent area based on the location information provided by the GPS receiver 113 and controls the camera unit 115 to photograph the illegally parked vehicle within the illegal parking intermittent area, And transmits the photographed position and photographing time information to the first server 131 together with the photographed image.

According to the embodiment, the parking lot intermittent portion 203 allows the camera unit 115 to photograph continuously ahead even if the illegal parking space is not provided, and provides at least one image per second to the first server 131 Thus, an administrator or a bus user can grasp road conditions in real time.

The passenger recognizing section 205 constitutes a "passenger counter" together with the phased array sensor section 117 to count the number of passengers who are getting on or off the bus 10. The passenger counter based on the operation of the passenger recognition unit 205 will be described below again.

The information collecting unit 207 periodically collects the temperature / humidity and fine dust concentration in the bus 10 measured by the sensor unit 111 and the number of riding and getting off passengers counted by the passenger recognizing unit 205 2 server 133, as shown in FIG. At this time, the information collecting unit 207 may count the number of passengers getting on and off in the unit of the boarding place confirmed by the position information provided by the GPS receiver 113, and provide the counted number to the second server 133.

In the meantime, according to the embodiment, the diurnal control unit 203, the passenger recognition unit 205, and the information collection unit 207 are not implemented as one integrated controller 119 as shown in FIG. 3, have. For example, the camera unit 115 and the diagonal intermittent interceptor 203 may be implemented as a single module, and the phased array sensor unit 117 and the passenger recognition unit 205 may be implemented as a 'passenger counter' module . In this case, the information collecting unit 207 can integrally control the emergency stopping unit 203 and / or the passenger counter.

(Embodiment 1) Passenger counter 1

Referring to FIGS. 4A and 4B, the passenger counter recognizes a passenger who rides or departs using the phased array sensor unit 117. 4 (a) and 4 (b), the region indicated by the dot (Dot) represents the beam emitted from the phased array sensor.

The phased array sensor unit 117 includes at least one phased array sensor provided at one side of the boarding gate 10a and the down gate 10b of the bus 10 or the boarding step of the gate thereof, ) And the getting-off gate 10b, or a passenger passing through the boarding stairs of the gate.

2, 3, and 4 (a) are diagrams for explaining how the two first phased array sensors 117a and 117b are arranged in parallel to each other to irradiate a beam in the vertical direction toward the stairs of the boarding gate 10a and the down gate 10b, (10a) and the lowering gate (10b), respectively. Since the range that one phased array sensor can cover is limited according to the installation method, it is possible to install two or more phased array sensors to cover the entire gate on a somewhat wide gate like the down gate 10b.

The beams of the first phased array sensors 117a and 117b are emitted to a plurality of channels. For example, if a 32-channel rider sensor is used as the first phased array sensors 117a and 117b, 32 distance values are output for each of the first phased array sensors 117a and 117b. Therefore, the first phased array sensor 117a and 117b can cover a certain range and can measure the distance to an object in its coverage. The passenger recognizing unit 205 distinguishes the output state of the phased array sensor unit 117 from a normal state and an event state.

(1) Steady state (Noraml State): When there is no passenger boarding (or getting off) the boarding gate (or getting off gate), the beam reaches the stairs. The passenger recognizing unit 205 can determine the steady state by storing the distance value output from the phased array sensor unit 117 in advance in the steady state.

(2) Event state: As the passenger is getting on (or getting off) the beam of some channels arrives at the head or shoulder of the passenger, the measured value of the beam of some of the 32 channels becomes smaller, for example. Since the passengers are larger than a certain size, the distance values measured by the first phased array sensors 117a and 117b in the event state are reduced to a certain pattern in some channels. The passenger recognizing unit 205 recognizes the occurrence of the event by recognizing the change of the 'distance value-output pattern', and recognizes that the passenger is boarding or getting off.

Therefore, the passenger recognition section 205 should retain the output pattern of the phased array sensor in the steady state and at least one output pattern of the phased array sensor in the event state. On the other hand, the output pattern of the phased array sensor is not uniform according to various sizes of the passengers' size, such as the child and the adult, the boarding position in the stairs, Therefore, the passenger recognizing section 205 judges whether or not the passenger is a passenger using the change of the output pattern of the phased array sensor, not the measurement value of the individual beam of the phased array sensor.

The passenger recognizing unit 205 can distinguish a state where the passenger is neither in the normal state nor in the passenger's getting on or off state by separately distinguishing the event state.

It is difficult for the passenger counter in Fig. 4 (a) to judge whether the passenger is getting on or off. Considering that the boarding gate 10a of the city center bus 10 is mainly boarding and the getting-off gate 10b is usually getting off, the number of passengers on board the bus 10 is estimated There is no problem.

(Embodiment 2) Passenger counter 2

Unlike the first embodiment, the second embodiment of FIG. 4 (b) is proposed in order to distinguish between a passenger's getting in and out. Referring to FIG. 4B, the passenger counter can distinguish whether the passenger is getting on or off by using the first phased array sensor 117a and the second phased array sensor 117c arranged in parallel to one gate .

Therefore, it is preferable that the first phased array sensor 117a and the second phased array sensor 117c are arranged in a line along the passenger's boarding or departing direction. As a result, the beams emitted from the first phased array sensor 117a and the second phased array sensor 117c are outputted in two rows side by side across the riding or getting direction of the passenger as shown in FIG. 4 (b).

For example, FIG. 4B shows an example in which the first phased array sensor 117a is disposed on the inside of the bus and the second phased array sensor 117c is disposed on the gate side. However, it is preferable that the first phased array sensor 117a and the second phased array sensor 117c are disposed adjacent to each other such that different passengers are not recognized.

The passenger recognizing section 205 recognizes the passengers using the outputs of the first phased array sensor 117a and the second phased array sensor 117c and outputs the signals to the first phased array sensor 117a and the second phased array sensor 117c are the same as those of the first embodiment described above. However, if the first phased array sensor 117a recognizes the passenger first and the second phased array sensor 117c recognizes the passenger subsequently, as shown in FIG. 4B, If the first phoneme array sensor 117a recognizes the passenger first and then the first phased array sensor 117a recognizes the passenger, it is determined that the passenger is being recognized.

(Embodiment 3) Providing information

A bus environment information collection method using the bus system 110 will be described with reference to FIG.

<Information Generation and Server Transmission: S501, S503>

The information collecting unit 207 grasps the position of the bus stop on the basis of the position information provided by the GPS receiver 113 and calculates the number of the passengers or the number of passengers provided by the passenger recognizing unit 205 And collects the current number of bus passengers.

The information collecting unit 207 provides the number of passengers and the position information calculated by the second server 133 through the wireless communication interface 201. At this time, the information collection unit 207 also provides temperature / humidity information and fine dust concentration in the bus 10 collected through the sensor unit 111 to the second server 133.

&Lt; Information is displayed to the user: S505 >

The second server 133 provides the kiosk of the related website or the bus stop to the information required to be disclosed to the general citizen among the information collected and provided by the information collection unit 207, As shown in FIG. Accordingly, the bus user can check the number of passengers who have boarded the buses consecutively next to the bus stop, and select a bus to ride.
