Description

  The present invention relates to a product improper loading prevention support system, and in particular, in a product distribution system in which a fluid product (for example, cement powder) is loaded while being metered together with a transport vehicle, and then left as it is after loading. The present invention relates to a product illegal loading prevention support system that can prevent unauthorized loading of products.

  Conventionally, when a product such as cement is loaded on a transportation vehicle, a vehicle weighing instrument is provided, and after weighing the tare weight of the entering transportation vehicle with the vehicle weighing instrument, the product corresponding to the transportation vehicle is A method is known in which loading is carried out while measuring and the difference from the previously measured tare weight is shipped as a net loading amount (see, for example, Patent Document 1).

  In addition, in such a device that measures the entire transported vehicle, a means for detecting whether or not the vehicle is placed on the vehicle weighing instrument is required prior to weighing, and as a means for detecting the vehicle, There are a method in which a non-contact ID card is read by a vehicle detector arranged on the side, a method in which a photoelectric tube is arranged on both sides of a vehicle measuring instrument through which the vehicle passes, and the vehicle is detected by blocking the photoelectric tube.

  By the way, in the vehicle detection means using the non-contact ID card, when the vehicle A on the vehicle measuring instrument is replaced with another vehicle B while the non-contact ID card is detected by the vehicle detection means, It cannot be recognized that the vehicle has been replaced. On the other hand, even in the case of a vehicle detection means using a phototube, if the vehicle A on the vehicle measuring instrument is replaced with another vehicle B while the light from the phototube is blocked by hand or the like, the vehicle is replaced. Has the disadvantage of not recognizing that it has been performed.

Therefore, in an unmanned product shipping site, etc., a person with malicious intent can not recognize the vehicle by the sensor, and replaces the empty subsequent vehicle B while the previous vehicle A is loading the product. If it is determined that the machine has loaded the product on the same vehicle A, the subsequent vehicle B will continue to load the product. However, what is actually recorded on the slip is only the difference between the maximum weight measured by the vehicle weighing instrument and the tare weight of the vehicle (net loading amount). It will be taken out.

To provide a stem.

  FIG. 1 is a schematic configuration diagram of a product unauthorized loading prevention support system shown as an embodiment of the present invention, and FIG. 2 is a control circuit block diagram of the product unauthorized loading prevention support system. In this embodiment, the case where a fluid product such as cement is shipped will be described as an example. However, the present invention is not necessarily limited to these fluid products.

  1 and 2, the product improper loading prevention support system corresponds to a position where the fluid product is loaded on the transport vehicle 10 (hereinafter, this position is referred to as “shipping position”), and the product loading device 11 and the vehicle. A measuring instrument 12 and a terminal post 13 are arranged. Further, a control device 14 serving as a host server for managing product shipment is provided at a location away from the shipping position. The vehicle measuring device 12 and the terminal post 13 are connected to the control device 14 via an intranet, the Internet, RS232C, RS422, or the like provided in the company. In addition, the control apparatus 14 may be arrange | positioned in the shipping position.

  On the other hand, the transport vehicle 10 that uses the product improper loading prevention support system has a non-contact type ID tag 15 in which vehicle identification information for each transport vehicle 10 is recorded. The ID tag 15 here is a data carrier generally called an IC tag, and an IC circuit having an antenna, a transmission / reception unit, and a memory is built in the tag. The ID tag 15 is carried by the driver and placed at a predetermined position of the terminal post 13 when receiving the product loading. The terminal post 13 recognizes the information, and the terminal post 13 is loaded after the loading. Necessary information can be written from the side.

  The feature of the ID tag 15 is that information can be exchanged in both directions, and it can be written as well as read. Also, it has a large memory capacity, and can store information of several kilobytes to several hundred kilobytes compared to character information of about 20 digits when, for example, a bar code or magnetic stripe is used. . Furthermore, it has good environmental resistance, and there is no problem even if oil or mud adheres. Further, it is more transmissive, and even if a substance other than metal exists between the ID tag and the antenna unit, it can be transmitted and communicated.

  The product loading device 11 is configured to be able to load a fluid product onto the transport vehicle 10 that has entered the shipping position. The vehicle measuring instrument 12 is provided at the shipping position provided on the travel path of the transport vehicle 10 and below the loading port 11 a of the product loading device 11. In this state, the transport vehicle 10 is weighed and the measured value can be output.

  The terminal post 13 includes a vehicle identifier 16, a display unit 17, a voice generation unit 18, a notification unit 19, a slip issuing unit 23, and a CPU 30 that controls the operation of the terminal post 13. When the operator places the ID tag 15 of the transport vehicle 10 into a predetermined position such as by inserting the ID tag 15 into the terminal post 13, the vehicle identifier 16 stores the ID information recorded in the memory of the ID tag 15. It has ID information / reading / writing means 16a for reading the information and outputting the information to the control device 14 and receiving the information from the control device 14 on the ID tag 15. The ID tag 15 stores information from the ID information / read / write means 16a in a memory.

  The display means 17 is a liquid crystal display device and digitally displays various information. The voice generation means 18 has a speaker and guides various information by voice. The informing means 19 has a function of displaying outside or notifying the outside by sound or the like when an abnormality occurs in the system. The slip issuing means 23 issues a shipping slip 24 to the transport vehicle 10 that has finished the product loading operation. The CPU 30 is connected to the vehicle identifier 16, the display unit 17, the utterance unit 18, and the notification unit 19, and controls various operations of the terminal post 13.

  The control device 14 includes a control circuit 20, a storage unit 21, an abnormality detection unit 22, and the like. The control circuit 20 is an arithmetic circuit (CPU) and controls the entire system according to a procedure programmed in advance in the storage unit 21. In addition to the above-described program for operating the control circuit 20, the storage means 21 also stores ID information and shipping information for each transport vehicle. The abnormality detection means 22 determines whether or not unauthorized shipping is performed in the transport vehicle 10 and outputs the information to the control circuit 20. In this abnormality detection means 22, a check weighing model value is prepared in advance. The check weighing model value is created based on the concept shown in FIGS. 3 and 4, for example.

  3 and 4 are flowcharts showing a concept for determining whether or not the shipment is normally performed by the control device 14, and FIG. 3 shows an illegal operation from the time when the transport vehicle 10 enters the shipping position until the time of shipment. FIG. 4 is a flowchart showing an example of a case where fraud is performed in the middle of loading. 3 and 4, (a) shows the movement of the transport vehicle 10 with respect to the vehicle meter 12, and (b) shows the measured value output from the vehicle meter 12 according to the position of the transport vehicle 10. Is shown in time series.

First, the transition of the shipping state shown in FIG. 3, that is, from the entry to the exit of the delivery position of the transport vehicle 10 to the exit, is accompanied by a change in the measurement value output by the vehicle measuring instrument 12 when processed normally. A description will be given in the order of (a) to (e).
(A) When the transport vehicle 10 enters the shipping position and the front wheels of the transport vehicle 10 are placed on the vehicle meter 12, the measured value gradually increases from zero.
(B) When both the front wheels and the rear wheels of the transport vehicle 10 are mounted on the vehicle measuring instrument 12, the initial weight of the transport vehicle 10, that is, the tare weight is measured.
(C) When product loading from the product loading device 11 to the transport vehicle 10 is started, the measured value of the vehicle measuring instrument 12 starts to gradually increase.
(D) The value obtained by subtracting the tare weight from the measured value of the vehicle weighing instrument 12 (that is, the measured value−the tare weight) is the value of the maximum load capacity (that is, the total weight−the tare weight) regulated for each transport vehicle 10. Then, the product loading by the product loading device 11 is completed, and the loading is stopped by the product loading device 11. Accordingly, the actual vehicle weighing value at this time is a value obtained by subtracting the tare weight from the total weight regulated for each transport vehicle 10.
(E) When the loading of the product is completed, the transport vehicle 10 starts moving in the direction of leaving the vehicle measuring instrument 12, and the front wheel of the transport vehicle 10 descends from the vehicle measuring instrument 12 to the ground, the measured value decreases. If the rear wheel gets down to the ground, the measured value becomes zero.

  That is, it can be seen that the measured value during normal shipment processing does not drop in the middle, and draws a line that continues to increase until loading is completed. Note that the amount of change in this curve also varies depending on the tare weight and maximum load capacity of the transport vehicle 10 and the loading speed of the product loading device 11. Therefore, if a reference table (hereinafter referred to as “check weighing model value”) in which the type of the transport vehicle 10 (tare weight or maximum load capacity) and the check weighing model value for each loading speed are recorded is prepared in advance. Using this weighing model value for checking, unauthorized monitoring becomes possible.

FIG. 4 is a transition of the shipping state when the transport vehicle 10 that has entered the shipping position tries to cheat in the middle of product loading. A description will be given in the order of (a) to (g) regarding the change in the measured value output by the vehicle measuring instrument 12 when this fraud is attempted.
(A) When the transport vehicle 10 enters the shipping position and the front wheels of the transport vehicle 10 are placed on the vehicle meter 12, the measured value gradually increases from zero.
(B) When both the front wheels and the rear wheels of the transport vehicle 10 are mounted on the vehicle measuring instrument 12, the initial weight of the transport vehicle 10, that is, the tare weight is measured.
(C) When product loading from the product loading device 11 to the transport vehicle 10 is started, the measured value of the vehicle measuring instrument 12 starts to gradually increase.
(F) When the value obtained by subtracting the tare weight from the measured value of the vehicle measuring instrument 12 becomes the value of the maximum loading amount regulated for each transport vehicle 10, the product loading by the product loading device 11 is completed. However, if a person with malicious intent performs the following work, for example, it is possible to make a fraud in the past.

  That is, in the case of management using an ID tag, the vehicle weighing device is kept in a state where the tag is set at the recognition position, and in the case of management using a phototube, the phototube is kept closed with a hand or the like. Before the value obtained by subtracting the tare weight from the measured value of 12 becomes the value of the maximum loading capacity, the transport vehicle A10 that is currently loading the product advances slightly and removes the front wheel from the top of the vehicle measuring instrument 12, When the front wheel of the empty transport vehicle B10 is placed so as to be replaced, the measured value of the vehicle measuring instrument 12 is once lowered. However, when the value obtained by subtracting the tare weight from the measured value does not reach the maximum load capacity, the next measurement is continued. The transport vehicle B10 can be loaded until the vehicle weighing instrument 12 obtains the same value as the maximum load capacity. However, as described above, when the loading process is normally performed, it is impossible to think that the measured value falls during loading. Therefore, it is the basic concept of the present invention to determine that the empty transport vehicle B10 has been illegally replaced when the measured value is lowered during loading, and when it is determined to be illegal, the product is loaded. Loading from the device 11 to the transport vehicle 10 is stopped.

  FIG. 5 shows an example of a processing procedure for preventing illegal loading of products using the concept of determining unauthorized loading of products based on the measured values from the vehicle measuring instrument 12 described in FIGS. 3 and 4. It is a flowchart. The operation in the product improper loading prevention support system having the configuration shown in FIGS. 1 to 4 will be described using the flowchart shown in FIG.

  First, the control circuit 20 monitors the measured value from the vehicle measuring instrument 12 and checks whether the weight has increased (step S1). Then, when the transport vehicle 10 enters the shipping position and is placed on the vehicle measuring instrument 12, and when the weight of the transport vehicle 10 is added to the vehicle measuring instrument 12 and becomes heavy, it is determined from the measured value that the transport vehicle 10 has entered. The product shipping process is started (step S2).

  Subsequently, when the operator of the transport vehicle 10 sets the ID tag 15 at a predetermined position of the terminal post 13 (step S3), the ID information of the ID tag 15 is read by the ID information / read / write means 16a, and the ID Information is input to the control circuit 20. The control circuit 20 identifies the transport vehicle 10 from the ID information (step S4), and then reads the check weighing model value corresponding to the transport vehicle 10 from the measured value of the vehicle weighing instrument 12 (step S5). This check weighing model value is a model value that is compared with the measurement value output from the vehicle weighing device 12 when the product is loaded by the product loading device 11, and the measurement value is abnormal based on this check weighing model value. It is determined whether or not there has been a simple movement (change).

  Next, when an operator such as a driver presses a measurement button (not shown) provided on the terminal post 13, the control circuit 20 temporarily stores the tare weight at that time (the weight of the vehicle when empty) (step S6). ).

  Further, when the operator sets the loading port 11a of the product loading device 11 in the transporting vehicle 10 and presses a loading button (not shown), the control circuit 20 can know from the weighing model value for checking. The maximum loading amount of the vehicle 10 is determined as the loading amount, and the loading operation is started. With this loading, the measured value from the vehicle measuring instrument 12 gradually increases (steps S7, S8, S9).

  The control circuit 20 sends the measured value from the vehicle measuring instrument 12 to the abnormality detecting means 22 as needed. The abnormality detection means 22 compares the check weighing model value with the measurement value from the vehicle weighing instrument 12, and determines that the normal loading process is performed when the difference is within the allowable error range. In the normal loading process, the check weighing model value is temporarily fetched, and the loading process based on the check weighing model value is performed until the maximum loading amount is reached (steps S10 and S11).

  Further, during loading, loading is performed while checking by the abnormality detection means 22. Then, the measured value is compared with the tare weight (step S12), and if it is determined that the fixed weight (maximum loading amount) based on the check weighing model value has been reached, the control circuit 20 controls the valve of the product loading device 11. To close the product loading (step S13).

  When the operator removes the loading port 11a of the product loading device 11 from the transport vehicle 10 and presses a weighing button (not shown), the control circuit 20 obtains from the vehicle weighing instrument 12 instead of the check weighing model value. The loaded amount is measured using the actual measured value to be sent to the storage means 21. Although the product loading operation is performed as described above, an illegal loading operation can be prevented by using the check weighing model value. That is, in the check weighing model value, if the transport vehicle 10 is identified and the tare weight (vehicle weight before loading) is known, the maximum load capacity of the transport vehicle 10 is also determined, and thus the remaining amount is entered. I understand that. Therefore, only the remaining amount is loaded, and when loading is completed, the actual measured value is compared with the check weighing model value, and if the difference is within the allowable range, it can be determined that the loading is normal, and conversely the allowable range is set. If it is far off, it can be determined that an illegal work has been performed.

  Here, assuming that the difference between the actual measurement value and the check measurement model value is within the allowable range, the slip issuing means 23 of the terminal post 13 issues the shipping slip 24 with the information from the control means 20. At the same time, the ID information / read / write means 16a of the terminal post 13 writes necessary information into the ID tag 15 based on the information (step S14).

  When the issuance of the slip and the writing of necessary information to the ID tag 15 are completed, the control circuit 20 clears the check weighing model value (step S15). The worker receives the slip and the ID tag 15 and leaves the vehicle. Thereby, the operation at the time of normal processing ends.

  Next, in the process of step S10, the difference between the check measurement model value and the actual measurement value is within the allowable error range in the comparison between the check measurement model value by the abnormality detection means 22 and the actual measurement value of the vehicle measuring instrument. If the actual measured value is significantly lower than the check weighing model value, the control circuit 20 performs an illegal loading process such as replacing the empty transport vehicle B10 in the middle of loading. Is immediately started, the valve of the product loading device 11 is immediately closed, and the product loading is finished (step S17). Further, if necessary, the notifying means 19 notifies the injustice, the utterance means 18 gives a voice warning, and the display means 17 also displays it.

  Further, the control circuit 20 calculates the amount loaded so far from the check weighing model value, stores it, and terminates the process when the vehicle is left (steps S18 and S19).

  Therefore, according to the product illegal loading prevention support system according to the present embodiment configured as described above, when unauthorized loading is performed in the product loading device 11, the unauthorized operation is automatically detected and loaded. Since it can be canceled, unauthorized operation during product loading can be reliably prevented. Further, since an IC tag is used as the ID tag 15, a large amount of information can be recorded, and more information can be handled using the ID tag.
