BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transportation vehicle load collapse monitoring system and method, and more particularly, to a transportation vehicle load collapse monitoring system and method thereof in which a driver and a management center can easily know the transportation vehicle transportation collapse.
[0002]
[Prior art]
A conventional load collapse monitoring system for a transport vehicle monitors a load collapse state during traveling and performs an operation so as not to cause a load collapse empirically depending on the loading state of the load. As described in Japanese Patent Publication No. 100773, in order for the driver to know the change in the state of the load at the driver's seat in real time, the load collapse state during the traveling of the load loaded on the loading platform is constantly monitored, and the load collapse In order to be able to alert you by issuing an alarm when the condition exceeds the allowable limit, the output from the vehicle speed sensor, the output from the steering angle sensor, and the output from the gravity sensor are taken in while driving and the load weight and A technology has been developed that can calculate the degree of possibility of cargo collapse and vehicle rollover based on the vehicle speed with respect to the steering angle, and output an alarm when the degree exceeds a predetermined level. That. Various other techniques for preventing the collapse of the load of the transportation vehicle have been developed.
[0003]
However, the above-described technology requires various types of sensors, and maintenance thereof is not easy.
[0004]
In addition, as mentioned above, it is also important to acquire various data on the transport vehicle to prevent the load from collapsing. However, when a cargo collapse occurs, it can be detected quickly to detect the collapse of the cargo. It is also important to have a technology that minimizes the damage and impacts that occur when a problem occurs. However, the conventional technology that detects the collapse of the load quickly and minimizes the damage and impact when the collapse of the load occurs is configured using a sensor that is relatively easy to maintain, and the generated collapse is automatically detected. There was no system that could quickly detect and notify the driver and minimize the damage and impact when the cargo collapsed due to the driver's quick response.
[0005]
For this reason, the load collapse of the loading platform usually occurs when the vehicle is moving, but it is difficult for the driving driver to grasp the status of the moving loading platform, so in most cases the load collapse In many cases, the transport vehicle keeps moving in a state where the cargo collapse has occurred, and in such a case, a great deal of damage usually occurs.

[0021]
Next, the operation of the sensors 103a to 103d shown in FIG. 1 will be described.
[0022]
FIG. 2 is an explanatory diagram showing the relationship between the load in the loading platform of the transport vehicle shown in FIG. 1 and sensors.
[0023]
As shown in FIG. 2, the sensors 103 a to 103 d in FIG. 1 include infrared transmission devices 201 a to 201 d that transmit infrared rays, and infrared reception devices 202 a to 202 d that receive infrared rays output from the infrared transmission devices 201 a to 201 d, respectively. Consists of That is, the sensors 103a to 103d are configured by operating the infrared transmitters 201a to 201d and the infrared receivers 202a to 202d in pairs. For example, the sensor 103a operates as a pair of an infrared transmitter 201a and an infrared receiver 202a.
[0024]
The infrared transmitters 201a to 201d are arranged and attached to one side surface of the loading platform 206, and the infrared reception devices 202a to 202d are opposed to the infrared transmission devices 201a to 201d on the other side surface of the loading platform 206, respectively. Placed and attached. If there is no load 203 between the infrared receiving devices 202a to 202d and the infrared transmitting devices 201a to 201d, the infrared receiving devices 202a to 202d are always in a state of receiving infrared signals from the infrared transmitting devices 201a to 201d.
[0025]
In the state where the load 203 is loaded on the loading platform and the loading operation is completed, when the sensors 103a to 103d are operated with the in-vehicle terminal in an operating state, the infrared ray transmitting devices 201a to 201d are in a loaded state of the load 203. In some cases, the transmitted infrared rays are blocked, and in some cases, the transmitted infrared rays are not blocked and are received by the corresponding infrared receivers.
[0026]
The control unit 102 sequentially checks the reception state of each infrared signal in the infrared receivers 202a to 202d at predetermined time intervals, and continues whether or not a change has occurred in the state of the load 203 at the completion of loading. And check.
[0027]
The control unit 102 continuously checks the reception state of each infrared signal of the infrared receiving devices 202a to 202d at predetermined time intervals continuously thereafter to determine whether or not a change in the state of the load 203 has occurred. Investigate.
[0028]
That is, the control unit 102 grasps the loading state of the entire loading platform at the time of completion of loading in a state where the loading to the loading platform is completed, continuously checks the loading status at a predetermined time interval, and It is possible to grasp the collapse of the load by detecting the change in the load state caused by the collapse of the load that occurs during the movement.
[0029]
Thus, the control part 102 can grasp | ascertain the state of the load of the whole cargo bed based on the information which shows the receiving state of the infrared signal read from the sensors 103a-103d.
[0030]
Next, the operation of the present invention will be described with reference to FIG.
[0031]
FIG. 3 is a flowchart showing an example of the operation in the cargo collapse monitoring system for a transportation vehicle according to the present embodiment.
[0032]
The operation when the load 203 is loaded on the loading platform 206 of the transport vehicle 100a and the in-vehicle terminal 105a is activated as shown in FIG. 2 will be described.
[0033]
In FIG. 2, after the load 203 is loaded on the loading platform 206 of the transport vehicle 100a, the in-vehicle terminal 105a is activated by starting the engine of the transport vehicle 100a by the driver, and the display indicating that the in-vehicle terminal 105a is activated. Is performed on the display operation unit 106 (S1).
[0034]
Further, the control unit 102 of the in-vehicle terminal 105a notifies the management center 120 of the activation of the in-vehicle terminal 105a via the network 110, and activates the sensors 103a to 103d of the loading platform 206 (S2).
[0035]
When the sensors 103a to 103d are activated under the control of the control unit 102, the external line transmission devices 201a to 201d of the sensors 103a to 103d transmit infrared rays, respectively.
[0036]
In the state of the load shown in FIG. 2, the infrared rays transmitted from the infrared transmission device 201d are blocked by the load 203 and are not received by the infrared reception device 202d of the sensor 103d, and the infrared rays are received by the other infrared reception devices 202a to 202c. The
[0037]
The control unit 102 checks the reception status of each infrared ray in the infrared receiving devices 202a to 202d, grasps that the load 203 of the loading platform 206 is in the state shown in FIG. 2, and performs the above-described operation in the sensors 103a to 103d. It is determined that there is a load 203 between the infrared transmitting device 201d and the infrared receiving device 202d based on the information on whether or not infrared rays can be received, and the state of the load when the loading operation is completed is grasped. Then, the display operation unit 106 displays on the display operation unit 106 that the load 203 of the loading platform 206 is in the state shown in FIG. 2 (S3).
[0038]
The driver can see the state of the load on the loading platform 206 displayed on the display operation unit 106 and know what state the load is loaded when the loading operation is completed. It is possible to grasp the state of the cargo.
[0039]
Moreover, the control part 102 notifies the management center 120 via the network 110 of the load status information which shows the status of the load when the loading operation is completed (S4).
[0040]
Also in the management center 120, the administrator can grasp the state of the load on the loading platform 206 of the transport vehicle 100a by information displayed on the load collapse monitoring unit 122 by a report from the transport vehicle 100a. Information indicating the loading state inside the loading platform 206 of the transport vehicle 100a, which is reported to the management center and displayed on the load collapse monitoring unit 122, is stored from the load collapse monitoring unit 122 into the database unit 123 (S5).
[0041]
After the loading operation is completed and the in-vehicle terminal 105a is started by starting the engine, the control unit 102 starts the transport vehicle 100a toward the transport destination, arrives at the transport destination, stops the engine, and stops the in-vehicle terminal. Until the operation of 105a is stopped, the infrared reception status by the sensors 103a to 103d of the loading platform 206 is continuously checked periodically at predetermined time intervals, and whether or not the load collapse of the load by the control unit 102 has occurred. The operation of monitoring is continued (S6).
[0042]
That is, the control unit 102 of the in-vehicle terminal 105a determines whether or not there has been a change in the infrared reception state of each of the infrared receivers 202a to 202d of the sensors 103a to 103d in the loading platform 206, that is, has received infrared rays until then. Regularly check whether there is a change from the state to the state where infrared rays are not received, or the change from the state where infrared rays were not received until then to the state where infrared rays are received. The operation of determining whether or not the collapse of the load of 100a has occurred is continued.
[0043]
If the control unit 102 of the in-vehicle terminal 105a detects that the cargo collapse has occurred during the movement of the transport vehicle 100a, the control unit 102 indicates to the display operation unit 106 that the cargo collapse has occurred. And the speaker 104 is activated to notify the driver of the transport vehicle 100a with an alarm sound (S7).
[0044]
Further, the control unit 102 notifies the management center 120 that the cargo collapse has occurred via the network 110 (S8).
[0045]
On the other hand, when the control unit 124 of the management center 120 receives a report indicating that the load collapse has occurred from the transport vehicle 100a, the control unit 124 displays the report on the load collapse monitoring unit 122, and returns to the load platform of the transport vehicle 100a. The in-vehicle terminal 105a of the transport vehicle 100a is notified to the in-vehicle terminal 105a of the transport vehicle 100a via the network 110 that the notification indicating that it has occurred (S9). (S10).
[0046]
As described above, in the transport vehicle 100a, the driver who has received a report about the occurrence of the cargo collapse from the speaker 104 of the in-vehicle terminal 105a with the alarm sound controlled by the control unit 102 knows the occurrence of the cargo collapse. The load collapse status of the load is determined based on the information displayed on the display operation unit 106 indicating the collapse of the load output from the control unit 102 and the information indicating the operation state of the sensors 103a to 103d of the loading platform 206. When the driver who knows the above has taken measures against the load collapse, and when the driver inputs information from the display operation unit 106, the control unit 102 also notifies the management center 120 of the input information. (S11).
[0047]
The driver input information notified to the management center 120 is displayed on the cargo collapse monitoring unit 122 and stored in the database unit 123 from the cargo collapse monitoring unit 122 (S12).
[0048]
The above-mentioned load collapse information notified to the management center 120 is stored in the database unit 123 and converted into a database, thereby analyzing the cause of the load collapse occurring in the load of the transport vehicle and improving the method of loading the load. Or it is used for grasping the worker of the load with much load collapse.
[0049]
In the above description, the case where a sensor using infrared rays is used to detect the occurrence of cargo collapse has been described, but the sensor of the cargo bed may be detected using a sensor using laser or ultrasonic waves. At this time, in the case of the laser, as in the case of the infrared ray, the presence or absence of the load is detected by whether or not the load blocks the signal by constantly transmitting and receiving signals by the transmission unit and the reception unit.
[0050]
In the case of ultrasonic waves, it consists of an ultrasonic transmitter and an ultrasonic receiver. The reflected wave of the ultrasonic wave transmitted by the ultrasonic transmitter is received by the ultrasonic receiver, and the difference in the time required from transmission to reception is received. Measure the distance to the reflection point of the ultrasonic wave and grasp the presence or absence of the load.
[0051]
In the above description, when notifying the driver of the information on cargo collapse, the speaker is notified of the alarm with an alarm sound. However, the driver uses the synthesized sound stored in advance in the in-vehicle terminal to send the driver to the driver. You may make it report with a synthetic sound.
[0052]
Also, in the above explanation, when the management center receives a report from the transport vehicle indicating that the cargo collapse has occurred, it returns that it has received a report indicating that the cargo collapse has occurred at the platform of the transport vehicle. It was explained that it was notified to the in-vehicle terminal of the transport vehicle via the network and that it was notified to the driver by the in-vehicle terminal, but the management center received a report indicating that the cargo collapsed and received the notification When there is an instruction from the manager in charge of the transportation center who has learned that the collapse of the transport vehicle has occurred to the driver of the transport vehicle in which the collapse of the cargo has occurred, input from the load collapse monitoring unit 122 This instruction information may be transmitted to the in-vehicle terminal by the control unit 124 of the management center.
[0053]
As described above, when the driver grasps the collapse of the load while the transport vehicle is moving, it is possible to take a quick response and minimize the damage caused by the collapse of the load. In addition, by grasping information on cargo collapse at the management center and creating a database, the above information can be used for business improvement such as reviewing the loading method.
[0054]
As described above, the load sensor detects the load collapse in response to the load collapse that occurs while the transport vehicle is moving, and informs the driver in operation via the monitoring center of the load collapse. Action can be taken.
[0055]
【The invention's effect】
As described above, the transportation vehicle load collapse monitoring system and method thereof according to the present invention include a vehicle mounted terminal and a sensor mounted in the loading platform on the transportation vehicle, and the vehicle mounted terminal monitors the load collapse of the load by the sensor.
