Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a transportation management system equipped with a display device that manages transportation information such as the type and weight of objects loaded onto a transportation vehicle, and displays an abnormality when the maximum loading capacity is exceeded or instructs directions. .

[Conventional technology]

Systems that measure the weight of objects carried by transport vehicles and manage the measured weight, type of object, and other transportation information have relied on humans. For example, in the field of construction and civil engineering, when construction is being carried out by multiple cooperative companies,
In order to manage the output of each cooperating business entity, an acceptance inspector known as a "mambotori" measures only the number of times a transport vehicle passes through a hopper, and aggregates and collects the data.
is managing. In addition, to measure the amount of soil to be transported, a loading weight meter with a scale structure called a can-can is buried and installed on the transport road, and the weight of the transport vehicle with the soil to be transported is measured. A configuration is known in which the weight of the cargo being measured (transported soil volume) is measured by subtracting the weight value of the transport vehicle when the cargo is empty. Information processing of transportation information, including soil volume data, relied on humans. Therefore, for example, in the vehicle management system disclosed in Japanese Patent Application Laid-Open No. 58-48187, transmitters are installed on the roadside at multiple points along the route of the vehicle to emit point numbers and other necessary information. It has a configuration that includes a receiver that receives information such as a point number from a transmitter, a clock that outputs the time when reception is received, and a storage device that stores information such as the time and point number from this clock. Are known. However, in the above configuration, the transmitter
Since data such as point numbers and weight measured by an axle load meter are only output unilaterally, the operation of each vehicle can only be managed. Therefore, the operator must judge the operating status by himself while looking at the input data, which is a troublesome task. In addition, weight scales are used to measure weight, but these cannot be easily moved and are used at work sites where the route of travel changes depending on the progress of the work. There is also the disadvantage that the weighing scale must be moved frequently.

[Example] Below, an example in which the transportation management system of the present invention is applied to a transportation management system for managing the weight of transported objects (transported soil) of a dump truck 10, which is an example of the transport body 1, will be described with reference to FIGS. This will be explained based on FIG. This transportation weight management system includes a transportation information setting device 2 mounted on a dump truck 10, a road control means 3 installed on the transportation road, and a transportation weight measuring device 4 that can be controlled by the road control device 3.
It consists of an abnormality display device 6 and a central management device 5 provided at a management center or the like at the work site. In this embodiment, the transportation information setting device 2 mounted on the dump truck 10 includes an on-vehicle setting device 20, a cargo indicator light 21 connected to the on-vehicle setting device 20, and an on-vehicle antenna installed on the vehicle. It consists of a combination with a transmitter/receiver 22 having 23. That is, the on-vehicle setting device 20
When the operator operates a switch, the type of the transported object S is displayed on the transported object indicator light 21 by lighting a combination of color-coded lamps. Additionally, transportation information is set in the transceiver 22 at the same time. This transport information includes identification data of the transport vehicle such as the vehicle number of the dump truck, affiliation data such as the corporate entity number, and loading side data such as the vehicle number of the loading machine (for example, shovel loader) for the material to be transported. , transport object attribute data such as the type of the transport object S, and other information necessary for transport management. In addition, when the dump truck 10 takes over and transports the object S from the loading machine 15 such as a shovel loader, the loading machine 15 as described above
The information No. 5 also serves as transportation information, but in this case, it is preferable that the loading machine 15 also be provided with a transportation information setting device 2' similar to that of the dump truck 10. In this case, the transportation information setting device 2' provided in the loading machine 15 includes an on-vehicle setting device 20', a transported object indicator light 21'a connected to this, and a vehicle number indicator light 2.
1'b, the operator of the loading machine 15 operates a switch on the on-vehicle setting device 20', and the type of the transported object S and the vehicle number are displayed in the above-mentioned object indicator light 2.
1'a and the vehicle number indicator light 21'b are illuminated. Therefore, the operator of the dump truck 10 receiving the cargo S from the loading machine 15 should visually check the cargo indicator light 21'a and vehicle number indicator light 21'b of the loading machine 15. The type of the transported object S and the vehicle number of the loading machine 15 are entered into the on-vehicle setting device 20 of the dump truck 10, and the above information is displayed by lighting on the transported object indicator light 21 on the dump truck 10, and at the same time, the transmitter/receiver Set to 22. On the other hand, this allows the operator of the loading machine 15 to check whether there are any incorrect settings on the dump truck 10 side, and also allows workers at the dump truck unloading area to Since the type of S can be visually confirmed, it is possible to
If there are various types of cargo, there is no risk of accidentally unloading the cargo to a different location. Next, the transportation information set in the transceiver 22 from the on-board setting device 20 of the dump truck 10 is
The signal is transmitted from the transceiver 22 to the road control device 3 via the on-vehicle antenna 23 by electromagnetic induction communication or the like. In the case of this embodiment, the road control device 3 is attached to a ball 31 installed on the transportation road, and includes a control means (not shown), a transmitting/receiving means, a clock means, and an external data recording means (storage section). It has The conveyance information can be transmitted and received to and from the conveyance information setting device 2 and the conveyed object weight measuring device 4 via the roadside antenna 32 provided on the tip side of the ball 31. Therefore, the road control device 3 uses the road antenna 32
A transportation information setting device 2 (transceiver 2
2) Communicating and inputting the transportation information set in step 2). Further, by the clock function of the clock means of the road control device 3, the passing time of the dump truck 10 is recorded as transportation information. A plurality of such road control devices 3 are installed at appropriate locations on the transportation route, and the road control device 3 installed at the measurement corner is further connected to the control device 40 of the transported object weight measuring device 4 installed nearby. A detection signal is given to measure the weight of the transported object. Here, the transported object weight measuring device 4 is a loading weight meter called a so-called can-can (which is buried in the transportation route and measures the weight of the transported object 1 together with the transported object S, and measures the weight of the transported object in an empty state recorded in advance). A device that measures the weight of the transported object S by subtracting the weight) In other words, it is a device that can measure the weight of the transported object S, and automatically measures the weight of the transported object based on the detection signal from the road control device 3. It is fine as long as it has a configuration that performs
In this embodiment, a device that measures the volume and weight by image processing is used as the transported object weight measuring device 4. Carrying object weight measurement device 4 using this image processing
is a measurement corner set at an appropriate location on the transportation path, and includes a background panel 41 installed in parallel on one side of the transportation path to cover up the background, and a TV installed at a position opposite to the background panel 41. camera 42;
An image processing device 43 inputs the image recorded by the TV camera 42 (optical image, the same applies hereinafter) and extracts only an image representing the external shape of the transported object S portion, and It is comprised of a volume and weight measuring device 44 that measures the volume and weight of the transported object S based on the base. That is, the background panel 41 is used to make the rear background uniform when the image input means inputs an image of the dump truck 10 with the transported goods S piled up on the vessel V. The case consists of a large white rectangular plate. Therefore, the dump truck 10 being transported is stopped in front of this background panel 41. The TV camera 42 is an example of the image input means of the present invention, and records an image centered on the portion of the cargo S piled up on the vessel V of the dump truck 10 stopped in front of the background panel 41. The conveyed object weight measuring device 4 may be operated manually, but is configured to automatically control a TV camera 42, an image processing device 43, and a volume and weight measuring device 44 by a controller 40. In the case of this embodiment, the transmitter/receiver 22 of the transportation information setting device 2 mounted on the dump truck 10 is transmitted to the road control device 3 installed on the road near the measurement corner.
When a predetermined signal is input to the road control device 3, a detection command signal for starting volume and weight measurement is output to the controller 40. Note that the road control device 3 may be one that receives the detection command signal transmitted from a central control device 5 provided at a central control center or the like at the site. Next, the image Ia recorded by the TV camera 42 (hereinafter referred to as the original image) is input to an image processing device 43 as an image processing means. This image processing device 43 converts an optical image into an electrical signal, performs measurement and analysis using image processing technology, and reads the image (original image).
This is a device that performs arithmetic processing to extract an image (hereinafter referred to as a processed image) Ib of only the transported object portion based on the image, and there are two types of processing means as shown in FIGS. 3 and 4. That is, it is roughly divided into subtraction (difference) processing means 43A and identification element extraction means 43B. The first subtraction (difference) processing means 43A is, for example, a TV image processor (TVIP) (product name: manufactured by Nippon Avionics Co., Ltd.) or an image frame memory.
Using an image processing device such as the IM series (product name: Ikegami Tsushinki Co., Ltd.), from the original image Ia input by the TV camera 42, images of the same vehicle (model) stored in advance by the recording means are obtained. Image of empty Bethel V on dump truck 10 (hereinafter referred to as
A method for converting the original image Ia and the comparison image Is into electrical signals by calling the comparison image (Is), erasing the common part, that is, the part overlapped as images, and extracting the remaining part, The processed image Ib of this remaining portion is output to the volume and weight measuring device 44. The second identification element extraction means 43B uses, for example, an image processing device such as an automatic visual inspection device (trade name: manufactured by Ikegami Tsushinki Co., Ltd.). The device uses a CCD camera combined with a wavelength spectroscopic filter instead of a normal TV camera 42 to record the target area, measures the reflection characteristics of the target area for each wavelength, and processes the resulting image. This is a method in which a specific wavelength is input to the device 43 and detected, and the external shape of the detected portion is extracted as a processed image, and this method has been put to practical use, such as in the selection of damage to the peel of mandarin oranges. Using this device, it is possible to directly extract an image of the external appearance of the transported object S by setting the wavelength of the transported object S color as a detection target. In this automatic visual inspection device, the color, that is, the reflection characteristic of a specific wavelength is used to detect the shape of the transported object S, but the identification elements are, in short, Any physical characteristic that can extract and identify S may be used, and it may also be a physical characteristic that extracts the processed image Ib based on, for example, a specific temperature or a specific density. Therefore, if the transported object S has a specific temperature, it can be detected by infrared rays, and if it has a specific density, it can be detected by the reflection rate or transmittance of a signal or radio wave. Next, in the case of the present invention, the volume and weight of the processed image Ib are measured based on its size and shape, so it must always be extracted at the same ratio. In addition, in the case of the subtraction (difference) processing method, it is further necessary to record the original image Ia so that the contour shapes of the common portion of the original image Ia and the reference image Is match. For this purpose, for example, the TV camera 2 and the transported soil S
By stopping the dump truck 10 so as to always maintain a constant distance from the vehicle and by always setting the height of the vessel V at a constant position, it is possible to record an image in which the common part is at a constant position at a constant distance. . However, instead of manual operation like this,
A normalization correction means 421 may be provided. This normalization correction means 421 () moves or rotates the TV camera 42 forward and backward, up and down, left and right, with reference to the objects S piled up on the Bethel V, and adjusts the photographing distance (focus) to the subject; A configuration in which control is performed so that the common part (Betssel V in this embodiment) is at a constant position on the recorded screen. () Original image Ia recorded by TV camera 42
By enlarging or reducing the image, or by correcting the distortion, a reference image (a mark with a predetermined color and shape provided at a predetermined position on a dump truck, etc.) or a common part of a comparison image (a shape of a certain part of a dump truck, etc.) is created. The same shooting ratio (same shooting distance) is used, and if the position of the comparison image on the recording screen is misaligned with the common part, the images themselves are moved based on the common part and are overlapped perfectly. Modify the image as shown below to obtain image Ia′ under the same recording conditions. Based on the image Ia' under the same recording conditions obtained in this manner, subtraction processing is performed with the comparison image Is, or extraction processing is directly performed based on a specific color or brightness to obtain a processed image Ib. () In the case of using the identification element extraction means 43B, in addition to the above, the volume and weight are directly measured by the volume and weight measuring device 4 based on the unmodified original image Ia, and the obtained measurement location is A configuration in which a measurement value under the same conditions is obtained by correcting and calculating based on the difference between the original image and a reference value (corresponding to a common portion of the reference image or comparison image). etc. In this embodiment, since the image is inputted from the side of the dump truck 10 using one TV camera 42, the image of the contour shape of the transported object S, that is, the processed image Ib is obtained as a flat two-dimensional image. Will be recorded. The following methods can be used to measure the volume or weight of the transported object S based on this two-dimensional image. () The volume is calculated by dividing the two-dimensional image vertically or horizontally and integrating the area of each. This provisional volume is based on the assumption that the transported soil is piled up under the same conditions in the three-dimensional direction. Then, from this temporary volume, the temporary center of gravity corresponding position calculation means 442 calculates the temporary center of gravity corresponding position. Based on the provisional center of gravity corresponding position calculated in this way, the loading form determining means 444 creates a categorized three-dimensional loading form pattern stored in advance in the recording means of the volume and weight measuring device 44. A loading pattern having the same or most similar tentative center of gravity position is determined from among them, and the three-dimensional shape of the two-dimensional processed image is estimated. Based on this estimated three-dimensional loading pattern, the volume calculating means 447 corrects the provisional volume value and calculates the volume of the transported object S. In addition, if the volume value measured experimentally or the weight value for each type and condition of each soil to be transported is entered as data in the loading pattern, the volume value or weight value corresponding to the selected loading pattern , it is easy to just call up the weight value. () In addition to the TV camera 42 that records the two-dimensional original image Ia, an auxiliary camera is used to photograph the three-dimensional shape of the transported soil by changing the shooting angle.
Dimensional direction (in this example, the upper surface in the width direction of the transported soil)
The loading state of the transported soil S is captured (correction means 443 using an auxiliary camera). Thereby, the loading shape measuring means 445 corrects the loading shape in the width direction to measure the three-dimensional loading shape, and the volume calculating means 447 calculates the volume. () Instead of the above method, the three-dimensional measurement means 446 synthesizes images of the transported object S from different angles using two (or more than one) TV cameras with different recording angles to create a three-dimensional image. It goes without saying that the captured volume calculation means 447 may measure the volume value. Incidentally, the volume of the portion stored in the vessel V that does not appear as an image is equal to the volume of the vessel V, so by adding up that part, the volume of all the objects S to be transported can be calculated. The weight is calculated by inputting the type (density) data, porosity data, and weather condition (in the case of rain, etc.) data of the transported object S to the weight calculation means 449 to the volume value thus measured. In this embodiment, the above parameters are input by the operator of the dump truck 10 to the on-vehicle setting device 20 of the transportation information setting device 2 mounted on the dump truck 10, and are inputted to the transmitter/receiver as described above. 22 to the road control device 3, relayed through the road control device 3, and input to the controller 40 of the transported object weight measuring device 4. Then, the weight calculation data is given to the weight calculation means 449 via the controller 40, and the weight is measured. A checking means 448 may be provided to check whether the volume value (or weight value) calculated in this way is correct. That is, when the volume and weight of the transported object S are estimated based on the working conditions of the transporter 1, for example, the transporter 1
is the motor scraper 12, the above-mentioned checking means 448 includes the following work information:
Enter the blade angle, width, and digging distance data, and measure the estimated excavated soil volume based on this data. Next, the checking means 448 determines whether or not the calculated transported soil volume value is included within a predetermined tolerance range of the measured estimated excavated soil volume, and if it is included, it is determined to be the correct weight, and if it is not included. If so, it is determined as an error and a predetermined signal is output. In the case of an error, it is preferable to perform the measurement again based on the above-mentioned signal or to use another measurement method to prevent measurement errors. The device 4 for measuring the weight of a transported object through image processing captures the external shape, such as when the transported object S is piled up in the transported object loading container of the transporter 1 and at least a portion of it rises from the transported object loading container. Therefore, the carrier 1 is not limited to construction machinery, transport vehicles, etc., and the type of the transported object S is not limited in any way, and can be applied to anything. Further, in the above embodiment, the image processing device 43 and the volume and weight measuring device 44 are constructed as separate bodies, but it goes without saying that one device having both functions may be used. Further, in this embodiment, a plurality of TV cameras 42, which are an example of an image input device, are installed at appropriate locations on the transportation route to form a plurality of measurement corners, and these plurality of TV cameras 42 are operated by camera switching. It is connected to the image processing device 43 via the device 45 (of course, it does not need to be provided in all road control devices 3). Therefore, when the dump truck 10 stops at the nearest measurement corner during transportation and exchanges transportation information with the road control device 3, a control signal is sent from the road control device 3 to the camera switch 45, A TV camera 42 that can be controlled by the control device 3 is enabled to record images, and this TV camera 42 is used to input images. In this way, when the device 4 for measuring the weight of a transported object using image processing is used, it is not necessary to install the device 4 fixedly on the transport path, and it can be easily moved.
A plurality of TVs are installed at appropriate intervals on the transportation path, and the camera switch 45 is used to
Only the camera 42 can be driven, making it possible to measure the weight of the transported object S regardless of location. Therefore, the face that moves as the work progresses,
Depending on the transportation route to be changed, the transported object S is placed at a suitable position.
Since the weight of the transported object S can be measured, there is no need to change the transport route or take a long detour to measure the weight of the transported object S. In this way, data on the volume and weight of the transported object S measured by the transported object weight measuring device 4 are transmitted from the transported object weight measuring device 4 to the road control device 3. As a result, the road control device 3 receives the vehicle number of the dump truck, the company to which it belongs, the type of the transported object S, the vehicle number of the shovel loader that received the load, the time when the dump truck passed the road control device, and the weight of the transported object. Transportation information such as the weight (net weight) of the transported object measured by the measuring device is input. Next, the road control device 3 is provided with an abnormality determination means in its control section, and the road control device 3
An anomaly display device 6 is connected to the anomaly display device 6 so that an anomaly can be displayed externally. The abnormality determination means provided in this road control device 3 determines whether the weight value measured by the transported object weight measuring device 4 is within the range of the maximum loading capacity corresponding to the model number of the dump truck 10 that is the object of measurement. If it is determined that it is outside the range, an abnormality signal is output to the abnormality display device 6,
Notify the operator of the abnormality. Further, the type data of the transported object S obtained through communication from the transport information setting device 2 is determined and stored in advance for the transported object that should pass through the transport route where the road control device 3 is installed. If it is determined that the transported object S is of a different type, the abnormality display device 6 can similarly display an abnormality display to that effect. In this embodiment, the abnormality display device 6 is configured to activate the road control device 3 when the checking means 448 used by the transported object weight measuring device 4 determines that the weight of the transported object S is inaccurate. The configuration is such that a predetermined abnormality is displayed via the As a result, the weight of the transported object is re-measured by the device 4 for measuring the weight of the transported object through an appropriate means, and the transport route of the dump truck 10 is changed. In this way, the transportation information input to the roadside control device 3 is transmitted via wired or wireless communication means to the central management device 5 installed at a management center at the work site, or sent to a memory body (memory pack). The above-mentioned data is stored in the central control unit 5, and the memory body is transferred manually and input into the central management unit 5. In this way, transportation information is transmitted from each road control device 3 to the central control device 5 consisting of a microcomputer.
are accumulated in This accumulated transportation information is processed using the information processing means of the central management device 5 to perform integrated transportation management. Here, the configuration for inputting the transportation information to the central management device 5 is not limited to the above embodiment; for example, the measured value data of the weight of the transported object is immediately sent from the transported object weight measurement device 4 to the central management device 5. , it may be configured to be integrated with other transportation information sent from the road control device 3 within the central management device 5. Alternatively, if the on-road control device 3 and the transported object weight measurement device 4 are integrated devices having the functions of the respective devices, the transportation information is sent from the integrated device to the central management device 5. It turns out. Based on the transportation information collected in the central management device 5 in this way, information processing is performed and transportation management is performed. Next, as shown in FIG. 5 as a transportation management system, a configuration is added that allows the operator to instruct transportation management or operation management based on the transportation information processed by the central management device 5 via the road control device 3. Good too. That is, the road control device 3 is located near the road control device 3.
A destination indicating display device 7 is provided which can be controlled by. When the central management device 5 determines the destination (unloading place) according to the type of the transported object S, the route order is sent to each road control device 3, and the road control device 3 and the corresponding unloading location or route information are stored. Then, by communicating with the transportation information setting device 2 of the dump truck 10 passing through the road control device 3, the information on the transported object S loaded on the dump truck 10 is determined.
Once the type of transport route is known, it is possible to determine whether or not the transport route is correct as a transport route according to the type, and if the transport route is incorrect, operation management such as displaying the correct route can also be performed. With such destination instructions, the central management device 5
The operation of each dump truck 10 can be controlled according to the operation status ascertained by the operator.

【Effect of the invention】

This invention takes advantage of the fact that the carrier stops when communicating with a road control device, sets the stopping position in front of a background panel, and inputs the entire image image using an image input device such as a TV camera. , it is possible to extract an image of only the transported object and accurately calculate its weight. In addition, for weight measurement, all that is needed is an image input means such as a TV camera and a background panel, so it is inexpensive and can be placed on each road control device, and the transport route of the transport object is It can be easily moved if changes are made. Then, the road control device inputs transportation information from the transportation information setting device of the transportation object, and also sends a control signal to the transportation object weight measurement device to measure the weight of the transportation object.
Based on this, if the transport weight of the transporter exceeds the maximum load weight, an abnormality is displayed externally, allowing the operator to operate with an appropriate load, resulting in excellent safety. Also, based on the information processed by the central management device,
Since destination instructions can be given to the operator of each dump truck from an overall perspective via the road control device, operational efficiency can be improved.
