DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle management system for a car carrier which manages vehicles loaded / unloaded on a car carrier such as a car carrier, and more particularly to a car carrier which can be collectively managed in an inboard office or the like. The present invention relates to a vehicle management device.

[0002]

2. Description of the Related Art Generally, a car carrier has 12 to 1 boats.
It has five layers of vehicle loading decks, and about 5,000 completed vehicles for export are loaded / unloaded.

[0003] By the way, in this kind of car carrier, the confirmation of the number of vehicles loaded on board and the confirmation of the number of vehicles unloaded from the inside of the ship can be performed both in Japan and overseas.
Conventionally, this is performed by visual confirmation of an operator.

[0004]

In the above-mentioned conventional vehicle management method, a worker for visual confirmation is always required, so that it is not easy to secure the number of workers and there is a possibility that counting errors may occur. There is a problem that the number of vehicles on board cannot be managed in real time. For this reason, it is not possible to confirm how many vehicles were loaded on which deck in the ship or how many vehicles were unloaded until the data visually checked by the workers on each deck immediately before departure.

[0005] If the number of vehicles scheduled and the actual number of vehicles measured before departure do not match, it is completely unknown what type of vehicle was loaded in which cargo compartment and the counting error occurred. It takes a lot of time to respond.

[0006] Further, it is usual that the driver is informed in advance in which cargo compartment the vehicle is to be loaded. However, if the instruction is incorrect or the driver misunderstands, the ceiling height is reduced. There is a possibility that a high vehicle may be loaded on a low deck, in which case a so-called top-down cargo accident may occur in which the head of the vehicle hits the ceiling of the deck.

SUMMARY OF THE INVENTION The present invention has been made in view of such a situation, and it is possible to accurately count the number of vehicles passing through a vehicle entrance and to manage the number of vehicles in real time, thereby preventing a loading error during cargo handling. It is an object of the present invention to provide a vehicle management device for a car carrier that can be used.

Another object of the present invention is to provide a car carrier management device capable of accurately counting only the number of vehicles to be measured even in the reverse case.

Another object of the present invention is to notify a driver of a vehicle of a danger when a vehicle having a height equal to or larger than the ceiling height of the deck is to be loaded, and to prevent the vehicle from crawling. Another object of the present invention is to provide a management system for a car ship that can be prevented.

Still another object of the present invention is to provide a management system for a car ship in which a magnetic sensor can be easily installed and a magnetic field change can be accurately detected for any type of vehicle. .

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 shows a vehicle management device for a car carrier according to an embodiment of the present invention.
A plurality of vehicle detecting means 3 installed at a vehicle entrance 2 such as a rampway, a slopeway or a passageway entrance of a cargo section; a vehicle counting means 4 for counting vehicles based on signals from these vehicle means 3; A display means 5 for displaying the result of counting by the vehicle counting means 4; the vehicle counting means 4 and the display means 5 are installed in, for example, an inboard office 6; By monitoring the vehicle, it is possible to collectively manage the vehicles during cargo handling.

As shown in FIG. 1, each of the vehicle detecting means 3 includes a vehicle detecting mechanism 7, a vehicle discriminating mechanism 8, and a mechanism 9 for preventing the vehicle from hitting. And moving objects other than the vehicle (such as workers and bicycles) are distinguished, the type and passing direction of the vehicle are detected by the vehicle detection mechanism 7, and the vehicle heading accident is detected by the heading prevention mechanism 9. It can be prevented beforehand.

That is, as shown in FIG. 2, the vehicle discriminating mechanism 8 includes, for example, two magnetic sensors 10a, which are arranged on the passage surface of the vehicle entrance 2 at intervals in the vehicle passing direction.
10b, so that the vehicle 11 can be distinguished from other moving objects based on a magnetic field change when the vehicle 11 passes through the vehicle entrance 2.

As shown in FIG. 2, the vehicle detection mechanism 7 includes an outer gate 12 and an inner gate 13 which are disposed on both sides of the vehicle entrance 2 with a space therebetween in the vehicle passing direction.
The two gates 12 and 13 are provided with a plurality of photoelectric sensors 1 at a vertical interval of, for example, 20 cm.
2a and 13a are provided respectively. In each of the gates 12, 13, the height of the vehicle 11 is detected based on the height of the photoelectric sensor 12a, 13a that has detected the vehicle 11, and the type of the vehicle 11 is determined from the height of the vehicle. And both gates 1
The passing direction of the vehicle 11 is detected depending on whether the photoelectric sensors 12a and 13a of the vehicles 2 and 13 detect the vehicle 11 first.

That is, the height of the vehicle 11 varies depending on its type, for example, a passenger car is less than 140 cm,
RV car less than 160cm, van wagon car 180cm
And less than 200 cm for trucks, less than 220 cm for large trucks and buses, and 220 cm or more for large construction machines. Therefore, based on which height position the photoelectric sensors 12 a and 13 a have detected the vehicle 11. By detecting the difference in the vehicle height dimension, the vehicle 11
Can be determined.

The photoelectric sensor 12a of the outer gate 12
If the vehicle 11 is detected first, and then the photoelectric sensor 13a of the inner gate 13 detects the vehicle 11,
2 is moving from the left end to the right end in FIG. 2, and conversely, the photoelectric sensor 13a of the inner gate 13 detects the vehicle 11 first, and then the photoelectric sensor 12a of the outer gate 12 detects the vehicle 11. In this case, the vehicle 11 is moving from the right end to the left end in FIG. Therefore, by using this difference, the passing direction of the vehicle 11 can be specified.

On the other hand, as shown in FIG. 3, the crawling prevention mechanism 9 includes a storage means 14 for storing the ceiling height of the deck,
Vehicle height signal from the vehicle detection mechanism 7 and storage means 14
And a comparing means 15 to which a ceiling height dimension signal from the apparatus is input. The comparing means 15 compares the two dimension signals to determine whether or not there is a risk of peaking. . Then, if the result of the determination is that there is a possibility that the level will reach a peak, a notification signal is output via the notification means 16.

As shown in FIG. 2, this notifying means 16
An alarm lamp 17 installed on the inside gate 13 is provided.
The driver of the vehicle 11 passing through is notified of the danger.

Next, the operation of the present embodiment will be described. When managing the vehicle 11, firstly, the vehicle detecting means 3 is installed at the vehicle entrance / exit portion 2 such as a ramp way of a car ship to manage the vehicle 11 and a slope way of each deck, and the ship interior office 6 Vehicle counting means and display means 5 are provided. Then, each vehicle detecting means 3 and the vehicle counting means 4 are electrically connected by a wired method or a wireless method.

In this state, loading or unloading of the vehicle 11 is performed. For example, when loading the vehicle 11, the number of vehicles 11 is counted by the following method.

That is, when the vehicle 11 to be loaded passes the ramp way, the vehicle detecting means 3 installed on the ramp way counts this vehicle 11. The vehicle 11 goes to a predetermined deck through the slope way. At this time, the vehicle detecting means 3 installed on the slope way counts the vehicle 11 as a loaded vehicle for each deck. This vehicle 11 further
The cargo is to be loaded in a predetermined cargo compartment through the passage entrance / exit. At this time, the vehicle detecting means 3 installed at the entrance / exit of each cargo compartment serves as a loading vehicle 11 for each cargo compartment. The vehicle 11 is counted.

That is, the total number of vehicles 11 loaded on the car carrier is counted by the vehicle detection means 3 installed on the ramp way, and the vehicles 11 are loaded on each deck by the vehicle detection means 3 installed on the slopeway. Vehicle 11
Is counted for each deck, and the vehicles 11 loaded on each cargo section in the deck are counted for each cargo section. Therefore, even if there is a missing vehicle 11, it is possible to easily know in real time which cargo compartment of which deck the missing vehicle 11 occurred.

Next, a specific counting method of the vehicle 11 in each vehicle detecting means will be described. Vehicle 1 shown in FIG.
When the vehicle 1 passes through the vehicle entrance 2, the outer gate 12
Of the photoelectric sensor 12a and the magnetic sensor 10a are both O
It becomes N and the entry of the vehicle 11 is confirmed.

When the vehicle 11 proceeds further along the vehicle entrance 2, not only the optical sensor 12a and the magnetic sensor 10a of the outer gate 12 but also the optical sensor 13a and the magnetic sensor 10b of the inner gate 13 are turned on. Thereby, the passing direction of the vehicle 11 is determined, and the vehicle 1
It is confirmed that the vehicle 1 is a vehicle other than the vehicle, such as a bicycle or a worker, and the vehicle 11 is determined by up to which height the photoelectric sensors 12a and 13a are turned on.
Is determined.

When the vehicle 11 further advances through the vehicle entrance 2, the outer gate 12 is kept in a state where the photoelectric sensor 13a and the magnetic sensor 10b of the inner gate 13 are kept ON.
The photoelectric sensor 12a and the magnetic sensor 10a are turned off, and the leaving of the vehicle 11 is confirmed.

When the vehicle 11 further advances through the vehicle entrance 2, the photoelectric sensor 13a and the magnetic sensor 10b of the inner gate 13 are also turned off, and the vehicle 11 is counted as a vehicle to be loaded.

If the height of the vehicle 11 counted by the vehicle detection means 3 exceeds the height of the ceiling of the deck, a crash may occur. Therefore, in the present embodiment, in such a case, the alarm lamp 17 is turned on to notify the driver of the vehicle 11. As a result, the vehicle 11 can be prevented from hitting the ceiling.

While the vehicle 11 is loaded, a vehicle different from the vehicle 11 to be loaded, for example, a work vehicle, may pass through the vehicle entrance 2, and in this case, the vehicles 11 to be loaded are also loaded. Will be counted.

However, since this kind of vehicle passes through the vehicle entrance 2 in the opposite direction before leaving the port and goes out of the boat, the vehicle entrance 2 is moved in the reverse direction from the counted number of vehicles. The number of vehicles that have passed is subtracted to obtain the final number of vehicles. Thus, the number of vehicles 11 to be loaded can always be accurately counted.

Thus, the number of vehicles 11 is counted by using two types of sensors which use different types of photoelectric sensors 12a, 13a of the gates 12, 13 and both magnetic sensors 10a, 10b. Therefore, only the vehicle 11 can be accurately counted, and the type of the vehicle 11 can be determined from the vehicle height dimension, so that the collective management of the vehicle 11 can be easily performed. The vehicle 1 passing through the vehicle entrance 2
1 can also detect the passing direction, so that the number of vehicles 11 to be loaded can be counted without error.

In the above embodiment, the vehicle 1
Although the case where the vehicle 1 is loaded has been described, the present invention can be similarly applied to the case where the loaded vehicle 11 is unloaded, and the same effect can be expected.

In the above embodiment, the magnetic sensors 10a and 10b and the photoelectric sensors 12a and 13a
Has been described at two locations with an interval in the vehicle passing direction, but may be provided at three or more locations. By increasing the number of installation locations, the type of the vehicle 11 can be more finely determined.

In the above embodiment, the case where a plurality of vehicle detecting means 3 are provided has been described. For example, when only the total number of the vehicles 11 is counted, one vehicle detecting means 3 is provided on the ramp way. If there are two ways, two units may be installed.
