DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS.
[0012]
FIG. 1 is a block diagram showing a configuration of an operation information providing system in a bus according to an embodiment of the present invention. In FIG. 1, a bus 52 equipped with an in-vehicle device 1 that can transmit and receive in real time with the center device 2 does not need to install on-road equipment for transmitting and receiving with the bus and the center. When the vehicle passes through the center device 2, transmission information such as the vehicle number, system information, arrival or departure stop, arrival or departure time is transmitted to the center device 2 in real time.
[0013]
FIG. 2 is a block diagram showing the configuration of the in-vehicle device according to the embodiment of the present invention. In FIG. 2, the in-vehicle device 1 includes a main body unit 11 that performs data control, a GPS acquisition unit 12 that acquires position information from a GPS satellite (not shown), and a communication control unit 13 that controls communication with the center device 2. And a system number reading unit 14 that is connected to a tape guide device (not shown) and the like and reads a current system number set in advance before operation.
[0014]
The center device 2 includes a communication control unit 21 that controls communication with the in-vehicle device 1, a data control unit 22 that converts information transmitted from the in-vehicle device 1 into various information, and a database unit 23 that accumulates data. And an application processing unit 24 that performs display processing on various terminal devices.
[0015]
Furthermore, the center device 2 is connected to a network, for example, an Internet network 56 that can be connected to the Internet, and can perform data communication with the Internet terminal 31 such as a personal computer in a home or office via the Internet network 56. A mobile phone terminal 32, a stop terminal 33 installed at the stop, and an operation management terminal 34 for providing the current position information of the operation bus to the operation manager are connected.
[0016]
Next, the operation of the operation information providing system in the bus according to the embodiment of the present invention having the above configuration will be described. The GPS acquisition unit 12 of the in-vehicle device 1 acquires position information from a GPS satellite (not shown) at regular intervals. Based on the position information acquired by the GPS acquisition unit 12, the main body unit 11 that performs data control performs a process of determining arrival at the stop 51 and determination of departure from the stop 51.
[0017]
FIG. 3 is a processing flow of arrival / departure determination at a stop performed by the main body 11 that performs data control of the in-vehicle device 1. In FIG. 3, the main body unit 11 that performs data control of the in-vehicle device 1 periodically collects position information from the GPS acquisition unit 12, and determines arrival / departure states in a state having the collected position information ( Step 31). When it is determined in step 31 that the vehicle is in the arrival state, the stop number is extracted from the system information read by the system number reading unit 14 (step 32). Thereafter, arrival determination is performed (step 33).
[0018]
Here, the positional relationship between the position of the stop and the area for determining arrival and departure will be described with reference to FIG. In FIG. 4, B, C, D, and E indicate the positions of the four points in the square area for determining arrival and departure, and A indicates the stop position, and the four points of B, C, D, and E above. It is supposed to be located in the center.
[0019]
Each stop is given a stop number (number: NO), and as shown in FIG. 5, the stop position is defined by latitude and longitude information corresponding to the stop number, and further corresponding to the stop number. As shown in FIG. 4, the positions of the four points (B to E) in the rectangular area for determining arrival and departure are similarly defined by latitude and longitude information.
[0020]
Therefore, the arrival determination performed in step 33 of FIG. 3 is obtained by acquiring the latitude and longitude that define the arrival and departure determination areas from the table shown in FIG. 5 and collected by the GPS acquisition unit 12 (latitude and longitude). This is performed by comparing with the information and checking whether the area has been entered (see black circle in section C in FIG. 6). This arrival determination is carried out for all stops that stop based on the system information.
[0021]
If there is a stop that has entered by executing step 33 in FIG. 3, it is determined as arrival and the vehicle number, current system information, stop number determined as arrival, current time, etc. are shown in FIG. 1 is transmitted to the communication control unit 21 of the center device 2 of FIG. 1 (step 34), and the process is terminated with the current state as the departure determination state (step 35). If there is no stop that has entered the arrival / departure determination area, the processing is terminated as it is (step 33).
[0022]
On the other hand, if it is determined in step 31 that the vehicle is in the departure state, departure determination is performed (step 36). The departure determination performed in step 36 is performed by acquiring the latitude and longitude that define the arrival and departure determination areas of the stop determined for arrival from the table shown in FIG. 5 and collecting the current position (latitude and longitude) collected by the GPS acquisition unit 12. This is done by comparing with the information and checking whether it has come out of the area (see black triangle in section C in FIG. 6).
[0023]
When leaving the area, it is determined as departure (step 36), and then it is determined whether or not the corresponding stop is an arrival / departure stop where arrival and departure are performed simultaneously (step 37). Then, if it is determined that the corresponding stop is an arrival / departure stop that performs arrival and departure at the same time (see the black rectangle in the section G in FIG. 6), even if it is determined to be a departure (step 36), Without transmitting data such as the position to the center apparatus 2, the current state is set to the arrival determination state (step 39), and the process is terminated.
[0024]
If it is determined that the station is not an arrival / departure stop, the communication number of the vehicle number, the current system information, the stop number determined as departure, the current time, etc. are communicated by the communication control unit 13 in FIG. The information is transmitted to the control unit 21 (step 38), the current state is set as the arrival determination state (step 39), and the process is terminated. If the departure determination in step 36 does not leave the area, the process ends.
[0025]
FIG. 6 is an image diagram for explaining the relationship between arrival determination / departure determination / departure determination and section movement. The bus moves through each section from left to right, and in FIG. Going to go up. As shown in FIG. 4, each stop is provided with a stop determination area surrounded by a square. As a specific determination, in FIG. 6, arrival determination information in section C (illustrated by a black circle). It is shown that departure determination information (shown by a black triangle) is obtained at the time of leaving the section C. Moreover, in the section G, it is shown that it is an arrival / departure stop where arrival and departure are performed at the same time, and arrival determination information (shown in black rectangles) is obtained.
[0026]
By executing the processing flow shown above, the information transmitted from the in-vehicle device 1 mounted on the bus 52 is collected by the communication control unit 21 of the center device 2, and the collected information is immediately sent to the data control unit 22. Deliver. The data control unit 22 creates estimated arrival time information, approach display information, required time information between main stops, and stop information on which the last bus has passed from the transmission information of each bus 52. The operation flow of the creation process in the data control unit 22 is shown in FIG.
[0027]
In FIG. 7, the data control unit 22 first determines whether the transmission information (see step 34 and step 38 in FIG. 3) of the in-vehicle device 1 delivered from the communication control unit 21 is arrival information or departure information (step 41). When it is determined that the transmission information is arrival information, a vehicle number is extracted from the transmission information, and a section between the stops where the vehicle previously existed is acquired (step 42).
[0028]
If the end stop of the section and the stop of the transmission information match (step 43), the required time deducted from the time of arrival of the end point of the section from the time of departure from the start stop of the section of the vehicle is calculated. (Step 44).
[0029]
Based on the time required for these buses, the following equation (1) is calculated. That is,
(Time required for the section) = a * (Time required for the bus that passed one car before)
+ B * (the time required for the bus that passed recently) ...... (1)
However, a + b = 1; a and b are arbitrary coefficients. The above formula (1) calculates the weighted average of the time required for the latest two buses, and uses that value as the time required for each section. It is.
[0030]
The required time of the section between the buses calculated as described above is added to calculate the required time between the main buses (step 44).
[0031]
On the other hand, if the transmission information is departure determination information in step 41, the vehicle number, the system information, the stop determined to be departure, the departure time, the end bus setting information are acquired from the transmission information, and from those information, First, it is determined in which stop section the bus exists (step 46).
[0032]
Next, take the stops that are scheduled to stop in the future from the system information, and if the stop is a stop that provides the estimated arrival time, all the points from the section where the bus exists to the stop that calculates the estimated arrival time Pick up the section between the bus stops, add the time required for the section between the bus stops calculated as in equation (1) above, add the departure time to the value, and get to the corresponding bus stop The estimated arrival time is calculated (step 47).
[0033]
Furthermore, it is checked based on the table of FIG. 8 whether the section where the bus currently exists corresponds to the section before three, two before, and one before at all the stops displaying the approach. If one of them is met, access display information such as passing through the previous three stops, passing through the previous stop, passing through the previous stop is created for the stop (step 48).
[0034]
Next, if a stop bus has been set, a stop bus information creation process for picking up a stop that has been determined to be a departure and a stop that has passed up to that stop from the system information and ending the stop is performed (step 49).
[0035]
In addition, when the stop where the transmission information is determined to be arrival is an arrival / departure stop where the arrival and departure are performed at the same time (step 45), in addition to the processing for the information determined as arrival (steps 42 to 44) , Processing for the information determined as departure (steps 46 to 49), determination of existing section (step 46), estimated arrival time calculation (step 47), approach display information creation (step 48), end-of-car information ( Processing such as step 49) is also performed.
[0036]
Various information such as estimated arrival time information, approach display information, end bus information, required time information between main stops, and section information created by the data control unit 22 as described above are stored in the database unit 23.
[0037]
In the application processing unit 24, when there is a data request via the Internet network 56 from the Internet terminal 31, the mobile phone terminal 32, the stop terminal 33, and the operation management terminal 34, the relevant data is retrieved from the database unit 23, and the request is made. To the Internet terminal 31, the mobile phone terminal 32, the stop terminal 33, and the operation management terminal 34 through the Internet network 56. The Internet network 56 is merely an example, and can be realized even with other network networks.
[0038]
FIG. 9 shows a data display example displayed on the mobile phone terminal 32 connected to the Internet network 56 described above. In the data display example of FIG. 9, items are presented with black diamonds, and data examples that can be displayed for each item are shown. However, these are merely examples, and the display form is not only characters but also illustrations. Needless to say, it can be processed and transformed as if it were included.
[0039]
【The invention's effect】
As is clear from the above description, the present invention can provide a free arrival time information, approach display information, etc. by selecting a stop freely without installing conventional road facilities, and in real time. Since the estimated arrival time and the like are created using the passage information, it is possible to provide more accurate information even on a road where the road is heavily congested and the traffic situation changes with time.
In addition, the present invention provides a rectangular stop determination area for each stop in advance, can be set in detail according to traffic conditions, and is an arrival / departure stop where the corresponding stop simultaneously arrives and departs. Even if it exists, there exists an effect that arrival determination can be performed correctly.
[0040]
In addition, since information such as estimated arrival time and access indication information related to the stop is provided via the network, not only the stop but also a vehicle user can use an internet terminal such as a personal computer or a mobile phone terminal, etc. Since such information can be easily obtained, convenience for the vehicle user is remarkably increased.
[0041]
On the other hand, since the current passing position information of the vehicle can be provided to the operation manager, operation instructions such as avoiding dango driving can be easily performed, so that the vehicle can be operated more efficiently.
