Description

  The present invention relates to a vehicle weighing method for measuring the mass of a vehicle such as a truck, and more particularly to a vehicle weighing method using an ETC (Electronic Toll Collection System) and a vehicle weighing system for implementing the method. .

  2. Description of the Related Art Conventionally, a vehicle weighing system that performs measurement of the mass of a vehicle loaded with a load using a punch card that can record information according to the position and number of punch holes has been widely used. In the case of such a vehicle weighing system, a punch card in which information necessary for weighing is recorded by punch holes is prepared for each vehicle, and the punch card is read by a reader to efficiently measure the vehicle. Can be done well.

  However, when a punch card is used, it is necessary for the crew of the vehicle to insert the punch card into the reader, and when the information needs to be rewritten, a new punch card must be prepared. Processing may be required.

Thus, a vehicle weighing system has been proposed that can automatically measure the mass of a vehicle using an RFID tag instead of a punch card (see, for example, Patent Document 1). When the RFID tag is used in this way, the receiver receives the information recorded on the RFID tag by wireless communication, so no special operation by the crew is necessary, and the information rewriting is performed with the punch card. There are advantages such as being easier.

A DSRC (Dedicated Short Range Communication) radio device 7 is connected via the interface box 11 so as to be communicable with the indicator 10.

  As shown in FIGS. 1 and 3, the truck scale 1 includes a platform 2 having a size capable of simultaneously mounting wheels 4 a, 4 b; 4 c, 4 d on both ends of each axle S 1, S 2 of the vehicle 4; Four load cells 3 a, 3 b, 3 c, 3 d provided at the lower four corners of the mounting table 2 are provided.

  In the present embodiment, a two-axis vehicle is illustrated as the vehicle 4, but the vehicle 4 may of course be a three-axis or more vehicle. In that case, the platform 2 needs to have a size that allows all of the wheels on both ends of each of the three or more axles to be loaded simultaneously.

  In the present embodiment, the track scale 1 includes four load cells 3a, 3b, 3c, and 3d. However, the number of load cells is arbitrary, and for example, six or eight load cells are included. It may be. Furthermore, although the load cell included in the track scale 1 in the present embodiment is an analog load cell, a digital load cell may be used. In the case of using a digital load cell, since the A / D converter is built in the load cell, the track scale 1 and the indicator 10 communicate digitally.

  As shown in FIG. 4, the mass signals of the load cells 3a, 3b, 3c and 3d are output to an A / D converter provided in the indicator 10 as will be described later.

  A loop coil 5 that functions as a sensor for detecting the passage of the vehicle 4 is embedded at a position immediately before the vehicle 4 enters the platform 2 of the track scale 1. As shown in FIG. 2, the loop coil 5 is connected to the indicator 10 so as to be communicable. When the vehicle 4 passes through the information of the loop coil 5, the indicator 10 can detect the change in inductance of the loop coil 5, and the indicator 10 indicates that the vehicle 4 is connected to the loop coil 5 according to the detection result. It is possible to determine whether or not the vehicle has passed above.

  In addition to the loop coil, for example, a photoelectric tube, an ultrasonic sensor, and Parkcentena (registered trademark) can be used as a sensor for detecting the passage of the vehicle 4.

  As described above, analog mass signals are output to the A / D converter 45 from the load cells 3a, 3b, 3c, and 3d of the track scale 1. In this case, the A / D converter 45 converts the analog mass signal into a digital mass signal, and outputs the digital mass signal to the CPU 41. In this case, the CPU 41 calculates the mass value of the vehicle 4 on the platform 2 of the track scale 1 based on the input mass signal.

  Note that mass signals are output from the load cells 3 a, 3 b, 3 c, 3 d of the track scale 1 at predetermined time intervals, and these mass signals are repeatedly output to the A / D converter 45. Then, the A / D converter 45 sequentially performs conversion into digital mass signals, and these digital mass signals are sequentially output to the CPU 41. As a result, the CPU 41 calculates the mass value of the vehicle 4 at predetermined time intervals.

  The communication I / F 46 is an interface used for communicating with an external device. The external devices here include the interface box 11 described above and the electronic mail receiving terminal 23 shown in FIG.

In the vehicle number field 44b, the vehicle number of the vehicle on which the ETC on-board unit is mounted is displayed in the axle number field 44c. Stores the number of axles of the vehicle. The total amount field 44d is obtained by measuring the total amount of the vehicle, the tare amount field 44e is the tare amount of the vehicle, and the net amount field 44f is obtained by subtracting the tare amount from the total amount of the vehicle. The measurement result of the net amount of the load is stored. In the present embodiment, the vehicle number, the number of axles, the total amount of the vehicle, the tare amount of the vehicle, and the net amount of the cargo, excluding WCN, are positioned as the vehicle attribute information in the vehicle information. By referring to the vehicle attribute information, it is possible to know the attribute of the vehicle, and therefore it is possible to identify one vehicle from a plurality of vehicle groups, that is, to specify the vehicle.

  The WCN, the vehicle number, the number of axles, and the tare amount of the vehicle are registered in the vehicle information DB 44 in advance. be registered.

  In the present embodiment, the tare amount of the vehicle is registered in advance in the vehicle information DB 44 as described above. However, it is not registered in advance as described above, and before performing the weighing operation described later, the vehicle 4 is weighed in a state where no load is loaded, and the weighing result is used as the tare amount of the vehicle 4 to obtain vehicle information. You may make it register in DB44.

(Operation example of vehicle weighing system)
Next, an operation example of the vehicle weighing system of the present embodiment configured as described above will be described with reference to a flowchart and the like.

[Outline of operation of vehicle weighing system]
First, an outline of the operation of the vehicle weighing system of the present embodiment will be described.

  FIG. 6 is a flowchart showing a schematic flow of the operation of the vehicle weighing system according to the embodiment of the present invention. As shown in the flowchart of FIG. 6, in the vehicle weighing system of the present embodiment, when the vehicle 4 to be weighed first enters the platform 2 of the track scale 1, it is determined that the vehicle 4 can enter. The vehicle approach process for informing the crew member of the vehicle is executed (S1001). After entering the vehicle or before entering the vehicle, the crew member performs an operation of inputting the measurement information necessary for weighing the vehicle in the vehicle 4 (S1002).

  Next, a vehicle entry confirmation process for confirming whether or not the vehicle 4 to be weighed has entered the platform 2 is executed (S1003). Then, based on WCN, the vehicle specific process which specifies the vehicle 4 to be measured is executed (S1004). Thereafter, a weighing process for the vehicle 4 is executed (S1005), and a weighing result output process for outputting the result of the weighing process to the crew is executed (S1006).

  Then, a toll collection process for collecting a toll determined according to the mass (the total amount of the vehicle or the mass of the load, etc.) is executed (S1007). Finally, it is confirmed that the vehicle 4 can be withdrawn from the platform 2. A vehicle exit process is performed to inform the crew member (S1008).

  In addition, each said process is omissible as needed. For example, if it is not necessary to collect charges, the charge collection process in step S1008 is omitted. Further, as will be described later, if the weighing information is stored in advance in the indicator 10, the in-vehicle operation in step S1002 is omitted.

  Moreover, it is also possible to change the order of each said process as needed, or to perform it simultaneously. For example, the order of the vehicle entry confirmation process in step S1003 and the vehicle identification process in step S1004 may be interchanged to identify the vehicle first, and then confirm the boarding of the vehicle. And vehicle boarding confirmation processing may be performed simultaneously. Further, the measurement result output process in step S1006 and the charge collection process in step S1007 may be executed simultaneously to output the measurement result and collect the charge.

[Detailed operation flow of vehicle weighing system]
Next, details of the operation of the vehicle weighing system of the present embodiment described above will be described.

<Vehicle approach processing>
FIG. 7 is a flowchart showing an example of the operation flow of the indicator, the DSRC radio device, and the ETC on-vehicle device included in the vehicle weighing system of the present embodiment, which accompany the vehicle approach processing. In addition, when this vehicle approach process is performed, it is assumed that the vehicle 4 is stopped immediately before the platform 2.

  First, the indicator 10 checks whether or not another vehicle is still on the platform 2 of the truck scale 1, and if it is determined that the vehicle 4 can enter the platform 2, the entry is made. Information indicating that entry is possible is transmitted to the DSRC radio device 7 (S11).

  When the DSRC wireless device 7 receives the accessible information transmitted from the indicator 10 (S21), the DSRC wireless device 7 transmits the received accessible information to the ETC on-vehicle device 6 by wireless communication (S22).

  When receiving the accessible information transmitted from the DSRC radio device 7 (S23), the ETC on-vehicle device 6 outputs a predetermined buzzer sound at the output device (S24). By this buzzer sound, a crew member of the vehicle 4 can know that the vehicle 4 can enter the platform 2.

  Note that the buzzer sound output from the ETC on-board device 6 does not notify the crew of the vehicle 4 that the vehicle 4 can enter the platform 2 but outputs from the ETC on-board device 6. This may be communicated by voice. In addition, it may be transmitted using the navigation system 21 connected to the ETC on-vehicle device 6. Hereinafter, an operation example when the navigation system 21 is used will be described.

  FIG. 8 is a flowchart showing an example of the operation flow of the indicator, the DSRC radio device, the ETC on-vehicle device, and the navigation system included in the vehicle weighing system of the present embodiment, which accompany the vehicle approach processing. Note that step S11 in the indicator 10, steps S21 and S22 in the DSRC radio device 7, and step S23 in the ETC on-vehicle device 6 are the same as those described above, and thus the same reference numerals are given and description thereof is omitted.

  When receiving the accessible information transmitted from the DSRC radio device 7 in step S23, the ETC on-vehicle device 6 transmits the received accessible information to the navigation system 21 (S25).

  When the navigation system 21 receives the accessible information transmitted from the ETC on-board device 6 (S31), the navigation system 21 displays the received accessible information on the display 21a (S32). As a result, the crew member of the vehicle 4 can know that the vehicle 4 can enter the platform 2.

  In the case of a conventional vehicle weighing system, a signal lamp controlled by an indicator is used to inform that the vehicle can enter the platform. In contrast, in the present embodiment, the vehicle 4 can be entered by the buzzer sound output from the ETC vehicle-mounted device 6 or the display on the display 21a of the navigation system 21. Can tell to the crew. This eliminates the need for special devices such as signal lights.

<In-vehicle operation>
As a result of the vehicle entry process, the crew member of the vehicle 4 who knows that the vehicle 4 can enter the platform 2 is necessary for weighing the vehicle using the input device of the ETC onboard unit 6. Enter the weighing information. Here, the weighing information includes the type of the load loaded on the vehicle, the name of the business operator who manages the vehicle, the maximum load amount described in the vehicle verification, and the like.

  The crew member causes the vehicle 4 to enter the platform 2 after completion of the in-vehicle operation. Note that the crew may enter the vehicle 2 before performing the in-vehicle operation and stop the vehicle 4 and then perform the in-vehicle operation.

  As described above, in the present embodiment, the vehicle crew is configured to input the measurement information to the ETC on-vehicle device, but the present invention is not limited to such an aspect. For example, the measurement information may be registered in advance in the vehicle information DB 44 together with the WCN, the vehicle number, and the number of axles. In that case, the in-vehicle operation is unnecessary.

<Vehicle boarding confirmation process>
FIG. 9 is a flowchart showing an example of the operation flow of the indicator provided in the vehicle weighing system of the present embodiment, which accompanies the vehicle boarding confirmation process.

  First, the indicator 10 detects the amount of change in inductance of the loop coil 5 by receiving the output signal from the loop coil 5 (S71). Then, the indicator 10 determines whether or not the vehicle 4 has passed over the loop coil 5 based on the amount of change (S72). If it is determined that the vehicle 4 has not passed (NO in S72), the indicator 10 returns to step S71. On the other hand, if it is determined that the vehicle 4 has passed (YES in S72), the indicator 10 recognizes that the vehicle 4 has entered the platform 2 of the track scale 1 and has been loaded onto the platform 2 ( S73).

  In this way, the indicator 10 that has confirmed that the vehicle 4 has entered the platform 2 performs the weighing process as will be described later.

  As described above, vehicle boarding confirmation may be performed by detecting the number of axles, instead of using a sensor such as a loop coil. The following is an example.

  FIG. 10 is a flowchart showing another example of the operation flow of the indicator provided in the vehicle weighing system of the present embodiment, which is associated with the vehicle boarding confirmation process.

  First, the indicator 10 acquires the number of axles of the vehicle to be measured from the vehicle information acquired as described above (S81). Hereinafter, the number of axles acquired in this way is referred to as “registered axle number”.

  Next, the indicator 10 executes an axle number detection process for detecting the number of axles of the vehicle 4 entering the platform 2 of the truck scale 1. In this axle number detection process, the indicator 10 determines whether or not the axle of the vehicle 4 has entered the platform 2 based on the change in the mass value of the vehicle 4 sequentially calculated by the CPU 41. More specifically, for example, the number of axles detection process is executed as follows.

  First, a value corresponding to the mass of the axle of the vehicle that can be measured (hereinafter referred to as “registered axle mass value”) is registered in advance in a register in the CPU 41 of the indicator 10. In addition, a lower limit value indicating a lower limit of mass that can be measured by the track scale 1 is registered in the other registers in the CPU 41 in advance. Then, each time the mass value is calculated, the CPU 41 compares the difference between the calculated mass value w and the lower limit value with the registered axle mass value. This comparison process is repeatedly executed until the difference between the mass value w and the lower limit value becomes larger than the registered axle mass value. Here, when the difference between the mass value w and the lower limit value becomes larger than the registered axle mass value, the CPU 41 determines that the axle of the vehicle 4 has entered the platform 2.

  The indicator 10 determines whether or not the detected number of axles (hereinafter referred to as “detected axle number”) matches the number of registered axles acquired in step S81 (S83). If it is determined that they do not match (NO in S83), the indicator 10 returns to step S82 and executes the axle number detection process.

  In this axle number detection process, the CPU 41 sets a predetermined threshold value for axle detection determination to a new lower limit value, and then, as described above, the difference between the mass value w and the lower limit value and the registered axle. By comparing with the mass value, the approach of the axle to the new platform 2 is determined. When the approach of the axle can be confirmed, the number of detected axles is incremented by one each time.

  The indicator 10 repeats steps S82 and S83 until the detected number of axles matches the number of registered axles. If it is determined that the number of detected axles coincides with the number of registered axles (YES in S83), the indicator 10 recognizes that the boarding of the vehicle 4 onto the platform 2 is completed (S84).

  By processing in this way, it is possible to check whether the vehicle has entered the vehicle based on the number of axles of the vehicle.

  The crew member of the vehicle 4 stops the vehicle 4 on the platform 2 when the vehicle 4 has been placed on the platform 2.

<Vehicle identification processing>
FIG. 11 is a flowchart showing an example of the operation flow of the indicator, the DSRC radio device, and the ETC on-vehicle device included in the vehicle weighing system of the present embodiment, which accompany the vehicle specifying process.

  First, the ETC vehicle-mounted device 6 transmits the WCN stored in the storage device and the measurement information input by the crew of the vehicle 4 to the DSRC radio device 7 by wireless communication (S41).

  When receiving the WCN and the measurement information transmitted from the ETC on-board device 6 (S51), the DSRC radio device 7 transmits the received WCN and measurement information to the indicator 10 (S52).

  When the indicator 10 receives the WCN and the measurement information transmitted from the DSRC radio device 7 (S61), it searches the vehicle information DB 44 using the received WCN as a key (S62). As a result of the search, the indicator 10 can acquire vehicle information including the WCN.

  Next, the indicator 10 specifies the vehicle to be measured using the vehicle number and the number of axles in the vehicle attribute information associated with the WCN in the acquired vehicle information (S63). And the indicator 10 produces | generates the measurement object information containing the vehicle attribute information which concerns on the specified vehicle, and the information for measurement received in step S61 (S64), and memorize | stores the produced | generated measurement object information in the memory 42. (S65).

  As described above, if the weighing information is registered in advance in the vehicle information DB 44, the indicator 10 determines that the weighing information and the vehicle attribute information included in the acquired vehicle information in step S64. What is necessary is just to produce | generate the measurement object information containing.

<Weighing process>
FIG. 12 is a flowchart showing an example of the operation flow of the indicator provided in the vehicle weighing system of the present embodiment, accompanying the weighing process.

  As a result of the vehicle boarding confirmation process described above, the indicator 10 that has recognized that the boarding of the vehicle 4 onto the platform 2 of the truck scale 1 has been completed is stopped based on the mass values sequentially calculated after the vehicle boarding confirmation process. The total amount of the vehicle 4 inside is acquired (S91). More specifically, for example, an average value of a plurality of mass values calculated from the end of vehicle boarding confirmation to a predetermined time is calculated, and the calculated average value is set as the total amount of the vehicle 4. Alternatively, the mass value at a specific point in time after completion of vehicle entry confirmation may be the total amount of the vehicle 4.

  Next, the indicator 10 reads the tare amount of the vehicle 4 from the vehicle information acquired as described above, and subtracts the tare amount of the read vehicle 4 from the total amount of the vehicle 4 acquired in step S91. Thus, the net amount of the load loaded on the vehicle 4 is acquired (S92).

  The indicator 10 updates the vehicle information by storing the total amount of the vehicle 4 acquired in step S91 and the net amount of the load acquired in step S92 in the total amount field and the net amount field in the vehicle information, respectively. (S93).

<Weighing result output processing>

  When the ETC in-vehicle device 6 receives the leaving information transmitted from the DSRC radio device 7 in step S211, the ETC on-vehicle device 6 transmits the received leaving information to the navigation system 21 (S213).

  When the navigation system 21 receives the leaving information transmitted from the ETC on-board device 6 (S221), the navigation system 21 displays the received leaving information on the display 21a (S222). As a result, the crew of the vehicle 4 can know that the vehicle 4 can be removed from the platform 2.

  As in the case of entering a vehicle, in the case of a conventional vehicle weighing system, a signal light controlled by an indicator is used to inform that the vehicle can be removed from the platform. On the other hand, in the present embodiment, the vehicle 4 can be removed from the platform 2 by the buzzer sound output from the ETC on-vehicle device 6 or the display on the display 21a of the navigation system 21. Can tell to the crew. This eliminates the need for special devices such as signal lights.

  In this embodiment, the indicator functioning as a vehicle weighing device and the DSRC radio are configured as separate devices. However, the present invention is not limited to such a form. The configuration may also serve as a DSRC radio.

  The vehicle weighing method and the vehicle weighing system according to the present invention can stably perform the weighing operation and can be configured at low cost.
