Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cargo handling vehicle confirmation method and device for confirming cargo handling vehicles at an automatic cargo handling base such as an oil depot that handles vehicles such as tank lorries and tank wagons.

In general, tank trucks and tank wagons that transport petroleum, etc. have a fixed load for each vehicle.
For example, if it is A heavy oil, only A heavy oil is transported. This means that when transporting different oils,
This is because the inside of the tank must be cleaned from time to time. At cargo handling bases such as oil depots, the type of oil transport vehicle is confirmed before cargo handling is carried out. Here, a conventional method for confirming cargo handling vehicles at a cargo handling base will be described below.

First, if a vehicle enters or leaves one cargo handling base, for example,
If there are around 100 vehicles, prepare a serial number card with a serial number from 1 to 100 recorded (magnetic recording, etc.) for each vehicle. Further, the type and loading amount of transportation oil of each vehicle are stored in a storage device (memory) along with the serial number. When the driver of the vehicle inserts the serial number card into the reading device during cargo handling, the serial number read from the serial number card is compared with the data in the storage device, and the type corresponding to the cargo handling vehicle is determined. The corresponding amount of oil is supplied.

By the way, in the conventional cargo handling vehicle confirmation method described above, if the driver forgets the serial number card, the driver goes to a reception desk or the like and declares the serial number. Then, the operator at the reception desk inputs this serial number using an input device or the like, and only then is the data in the storage device and the serial number compared. Furthermore, when handling cargo on a vehicle that does not have a serial number, the same troublesome procedures as in the case described above are required.

As described above, the conventional cargo handling vehicle confirmation method requires a serial number card, and therefore has the disadvantage that if the driver forgets the serial number card, he or she must carry out extremely troublesome cargo handling procedures.

This invention was made in view of the above-mentioned circumstances, and does not require any serial number cards etc.
It is an object of the present invention to provide a method and device for confirming a cargo handling vehicle that can eliminate the need for on-site procedures by the driver.

In order to achieve the above object, the first invention includes a first step of determining whether or not there is an object in the detection area by setting the approach road of the vehicle to the cargo handling base as a detection area; In the first process, the first
a second process in which it is determined that a vehicle has passed if the object is detected for a predetermined period of time or longer; and after it is determined that a vehicle has passed in the second process, the detection of the object in the first process is intermittently a third step of determining that the vehicle is passing continuously if the object is detected and the time during which the object is not detected is less than or equal to a second predetermined time; A fourth step of photographing a unique number such as a vehicle number or serial number displayed on a vehicle corresponding to the timing at which passing or continuous passing is determined; and an image of the vehicle photographed in the fourth step. a fifth step of storing the video, a sixth step of reproducing the video stored in the fifth step, and a step corresponding to the unique number reproduced in the sixth step. and an eighth step of searching for the cargo handling data corresponding to the input unique number.

Further, in the second invention, a sensor is provided that sets a vehicle approach road to a cargo handling base as a detection area and outputs a detection signal when an object is present in the area, and the output of the detection signal is maintained for a first predetermined time or more. a vehicle determining means that determines that a vehicle has passed in a certain case; and a second period of time during which the detection signal is intermittently output and no detection signal is output after the vehicle determining means determines that a vehicle has passed in a certain case; a continuous passage detection means that determines that vehicles are passing continuously if the predetermined time of a video storage device for storing video information obtained by the photographing device; a driving device for driving the video storage device in response to vehicle detection timing of the vehicle determination device and the continuous passage detection device; a display device for displaying a reproduced image of a video stored in the means; an input device for inputting codes corresponding to the unique numbers displayed on the display device; and cargo handling data corresponding to each of the unique numbers. a storage device for storing the cargo handling data, a storage device for storing the cargo handling data corresponding to the unique number input from the input device, and a processing device for searching the cargo handling data corresponding to the unique number input from the input device. It is characterized by the following:

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. Note that this embodiment is an embodiment at a cargo handling base that handles tank wagons.

In this figure, reference numeral 1 denotes a storage device, which stores cargo handling data for each tank wagon (vehicle) and a unique number (serial number in this embodiment) that corresponds one-to-one with each wagon. Reference numeral 2 denotes an input device equipped with a keyboard 2a, through which an operator 15 inputs a unique number into the processing device 3 through key operations. When the processing device 3 receives the unique number from the input device 2, it searches for cargo handling data corresponding to this unique number, outputs this cargo handling data to a cargo handling control unit (not shown), etc., and also outputs the cargo handling data corresponding to the unique number. The freight car number to be displayed is displayed on the monitor display 4. On the other hand, 5a and 5b are a light emitting section and a light receiving section, respectively, and output signals thereof are supplied to input terminals of the vehicle detection section 6, respectively.
In this case, when the tank wagon 10 entering the cargo handling depot blocks the light 1 emitted from the light emitting section 5a, the vehicle detection section 6 supplies a detection signal _S1 to the recording control section 7. The recording detection 7 controls the recording of the freight car number of the tank freight car 10, and its configuration is shown in FIG. In this figure, 20 is a passage detection circuit, and the detection signal S ₁
is supplied for a predetermined time _T1 or longer, it is recognized that a tank wagon has passed and outputs signals _S3 to _S5 . this signal
_S3 to _S5 have the same waveform as the signal _S1 , but the first rise time is delayed by the signal _T1 with respect to the signal _S1 .
This time T ₁ is shorter than the time it takes for one tank freight car to pass the irradiation light l of the light emitting part 5a.If a person, etc. passes the irradiation light l, the detection signal _S1
It is designed to be turned off within _T1 , so that the signals _S3 to _S5 are not output, thereby preventing malfunction of the device. 21 is a camera power control section, and a signal
When S ₃ is supplied, it outputs a signal S ₂ that turns on the camera control unit 8 . 23 is a video start control section which, when supplied with the signal _S4 , outputs the signal STA (see FIG. 3) at the first rise of the signal _S4 . This signal STA is a recording start signal for the video recorder 11 shown in FIG. Therefore, the signal
When S ₃ and S ₄ are output, the camera control unit 8 shown in FIG.
The video is recorded on the video recorder 11. 22
is a timer, which supplies signal S ₆ to the camera power supply control unit 21 from the time when signal S ₅ (this signal has the same waveform as signal S ₁ as described above) is supplied, and also when S ₅ is turned OFF. If it does not turn OFF for a predetermined time _T2 or more even after the temperature rises, the signal _S6 continues to be output. Once the camera power control unit 21 is supplied with the signal S ₃ , it continues to output the signal S ₂ even if the signal S ₃ is turned off as long as the signal S ₆ is supplied. This means that when the vehicle 10 becomes a formation vehicle and passes the irradiation light 1, the signal S ₁ is turned OFF at each connected portion.
This is to keep the video camera 9 operating even when the vehicle is connected to the vehicle. Also, the timer 22 indicates that the signal _S5 is the time
When _T2 or more is OFF, the signal _S6 is stopped, the signal _S8 (see Fig. 3 D) is sent to the lamp drive circuit 25 and the buzzer drive circuit 26, and the signal _S9 (same signal as _S8 ) is sent to the video stop control section 24. supply to When the video stop control section 24 receives the signal _S9 , it outputs a signal STO (FIG. 3) which causes the video recorder 11 to stop recording. Reference numerals 30 and 31 are a system reset button and a buzzer reset button, respectively, and when each button is pressed, reset signals _R1 and _R2 are output, respectively.
Reference numeral 29 denotes a rewind start control section, which outputs a signal RWS (FIG. 3 H) for rewinding the video recorder ₁₁ when the reset signal R2 is supplied. 28 is a rewinding completion detection unit, which outputs a rewinding completion signal RWE (third
When the signal S10 is supplied from the video recorder 11, the signal _S10 is supplied to the lamp drive circuit 25. 27 is a counter reset control section, which outputs a reset signal.
When _R1 is supplied, a counter (not shown) of the video recorder 11 is reset. The buzzer drive circuit 26 drives the buzzer 13 when the signal _S8 is supplied, and when the reset signal _R2 is supplied, the buzzer drive circuit 26 drives the buzzer 13.
to stop. The lamp drive circuit 25 causes the lamp 14 to blink when the signal S ₈ is supplied, turns on the lamp 14 when the signal S ₁₀ is supplied, and turns off the lamp 14 when the reset signal R ₁ is supplied. light up Returning to FIG. 1, reference numeral 12 denotes a CRT (cathode ray tube) display for reproducing the recorded contents of the video recorder 11. The CRT display device, the operation panel of the video recorder 11, the buzzer 13, and the lamp 14 are provided near the operator 15.

Next, the operation of this embodiment having the above-described configuration will be explained with reference to FIGS. 1 to 3.

When the vehicles 10 approach a cargo handling terminal in a combination of three vehicles, for example, the signal _S1 has a waveform as shown in in of FIG. 3A. and the first rise time of signal S ₁
After time t ₁ , signals S ₃ to _{S 5} are output from _the passage detection circuit 20, and the signal STA is output from the video start control unit 23 as shown in FIG. 3, and the camera power control is performed. A signal S ₂ is output from the section 21 . As a result, recording of the vehicle 10 is started. Note that FIG. 3 shows the recording timing of the video recorder. Then, the signal _S1 is turned off at the vehicle connection portion, but the signal _S2 continues to be output as described above. Next, the third tank wagon 1
0 passes, the signal S ₁ turns OFF at t ₂ ,
When the time T ₂ has elapsed from this time t ₂ , the timer ₂₂ outputs the signal S ₈ ,
The signal S ₆ is stopped at the same time as the signal S ₉ is output. As a result, at time _t3 , the camera power control unit 21 stops the signal _S2 to stop the operation of the camera control unit 8, and the video stop control unit 24 outputs the signal STO as shown in FIG. 11 recording stops (see the same figure). Furthermore, at time _t3 , when the signal _S8 is output, the lamp drive circuit 25 blinks the lamp 14 (see section TF in Figure 3), and the buzzer drive circuit 26 drives the buzzer 13 (see Figure 3). reference). On the other hand, operator 15
When the lamp 14 flashes and the buzzer 13 sounds, the operator knows that recording of the tank wagon 10 has ended. Then, when the operator 15 presses the buzzer reset button 31, a reset signal _R2 is output as shown in FIG. 3B, and the buzzer 13 stops sounding.
(See Figure 3) Also, the rewind start control section 2
9, the signal RWS is outputted as shown in FIG. 3H, and rewinding of the video recorder 11 is started (see FIG. 3W). Here, FIG. 2Y shows the counter value in the video recorder 11, and the counter value becomes "A" at the end of recording (time _t3 ). When rewinding of the video recorder 11 is completed and the counter value becomes "0" at time _t4 , for example, a signal RWE (FIG. 3) indicating completion of rewinding is sent from the video recorder 11 to the rewinding completion detection unit 28. Supplied. As a result, the signal _S10 from the rewinding completion detection section 28 is sent to the lamp drive circuit 25.
The lamp 14 enters a blinking state.

Here, the operator 15 uses the video recorder 11
Operate the operation panel (not shown) of the tank wagon 1.
0 is reproduced on the CRT display device 12. Then, the freight car number of the tank freight car 10 is read from the playback screen. At this time, if the tank wagon 10 is moving quickly, the user operates the operation panel to set the playback screen to slow motion or stop motion and read the wagon number. Next, the serial number corresponding to the read freight car number is input using the input device 2. In this case, the input device 2 is the freight car number→
If it has a serial number conversion function, input the read freight car number as is. Next, the processing device 3 retrieves the cargo handling data corresponding to the supplied serial number and outputs it to the cargo handling control section, etc., and displays the freight car number corresponding to the serial number on the monitor display 4. At this time, operator 15
CRT display 12 and monitor display 4
By comparing the screens, you can know whether the input serial number (or freight car number) is good or bad.
Then, the operator 15 presses the system reset button 3.
When 0 is pressed, the reset signal R ₁ (see Figure 3, C) is output, and the lamp 14 is turned off (see Figure 3, R).
The timer 22 and passage detection circuit 20 are reset. Also, the counter reset control section 27 sends a signal.
CUR is output and the counter of the video recorder 11 is reset again. From then on, new tank wagons can be accepted immediately. Even if a tank wagon enters the tank before the system reset button 30 is pressed (see out in FIG. 3), the recording operation will not be performed all at once.

In the above embodiments, the case of shipping has been described, but it goes without saying that the same applies to the case of receiving goods.

As explained above, according to the present invention, a unique number such as a vehicle number is recorded, the recorded unique number is played back and displayed, and the unique number can be inputted based on this. Since the present invention is designed to identify the passing of other objects and to detect the continuous passing of vehicles, the following effects can be obtained.

It is possible to reliably input the unique number of a vehicle without stopping the vehicle as it enters the vehicle regardless of operator's operation.

The operator's monitoring effort at the time of vehicle entry is greatly reduced.

Since the operator can read and input the number from the reproduced image, there is no need for a vehicle number card or the like.

For the same reason as above, there is no need to stop by the reception desk even if you do not have a vehicle number card etc.
