The communication means 41 transmits the various data stored in the memory 42 in response to a call from the dangerous goods license reader 24. The battery 43 supplies power to the communication unit 41 and the memory 42.
[0037]
d) Next, the electronic license plate 3 will be described with reference to FIG.
The electronic license plate 3 is an electronic license plate that stores vehicle ID data for distinguishing vehicles, and transmits the vehicle ID data in response to a call signal from the outside (for example, a communication device installed on the road side). To do.
[0038]
In particular, the electronic license plate 3 according to the first embodiment functions as a communication unit when the vehicle management device 2 communicates with the outside, as will be described in detail later.

The communication circuit 21 is a circuit for communicating with the outside using the communication antenna 23.
[0040]
e) Next, the basic operation of the vehicle management apparatus 2 of the present embodiment will be described.
The ID data stored in the dangerous goods license 1 is read by the dangerous goods license reader 24 to determine whether or not the dangerous goods license 1 is appropriate. Here, that the dangerous goods license 1 is appropriate means that the ID data coincides with any of the ID data of the dangerous goods handler license holder recorded in the memory 13 of the vehicle management device 2 in advance.
[0041]
When the dangerous goods license 1 is not appropriate, the warning display lamp 35 of the vehicle management device 2 is turned on, and the external communication means (the electronic license plate 3, the communication satellite antenna 4b, the telephone antenna 4c), and the related organizations. Communication is performed and a command to stop the engine is issued to the ignition ECU 33.
[0042]
On the other hand, when the dangerous goods license 1 is appropriate, the warning display lamp 35 is not lit and communicated, and the engine can be started.
Also, when sensor signals sent from the sensors (tank pressure sensor 5, tank liquid level sensor 6, tank gas sensor 7, tank temperature sensor 8) to the dangerous goods license reader 2 are out of the normal range (that is, loaded dangerous goods) Is in an abnormal state), the warning display lamp 35 is turned on and communication with related organizations is performed.
[0043]
f) Next, processing performed by the vehicle management device 2 of the present embodiment will be described in detail based on the flowcharts of FIGS. 4 and 5.
In step 100, the sensor detects that the ignition key switch 32 of the vehicle is turned on, and sends the signal to the data processing circuit 10 through the in-vehicle sensor signal processing circuit 19.
[0044]
In step 110, the data processing circuit 10 is activated. At this time, a program stored in the memory of the data processing circuit 10 (a program for performing subsequent steps) is loaded into the RAM of the data processing circuit 10.
In step 120, other circuits connected to the data processing circuit 10 (for example, dangerous substance state management system (sensors 5 to 8, dangerous substance sensor signal processing circuit 15 for taking in and processing this sensor signal), vehicle Communication I / F with ECU and external communication means (I / F with 4a, 4b, 4c, 12, 16, 17) are activated.
[0045]
In step 130, it is determined whether or not a sensor signal indicating that the driver is in the seat is sent from the seat sensor 30 to the data processing circuit 10 (through the in-vehicle sensor signal processing circuit 19). Here, if an affirmative determination is made, the process proceeds to step 140, while if a negative determination is made, the process returns to step 130 again.
[0046]
In step 140, an instruction to insert the dangerous goods license 1 into the dangerous goods license reader 24 of the vehicle management device 2 is displayed on, for example, a display unit (not shown) provided on the dashboard.
In step 150, it is determined whether or not the dangerous goods license 1 is inserted in the dangerous goods license reader 24.
[0047]
That is, the data processing circuit 10 transmits a polling signal for the dangerous goods license 1 through the dangerous goods license reader 24 (the communication circuit 11 and the dangerous goods license antenna 18). At this time, if the dangerous goods license 1 is inserted in the dangerous goods license reader 24, the dangerous goods license 1 receives the polling signal and transmits a command in response thereto. The response command is received by the dangerous goods license antenna 18 and sent to the data processing circuit 10 through the communication circuit 11.
[0048]
On the other hand, when the dangerous goods license 1 is not inserted, a response command is not sent to the data processing circuit 10.
In other words, the presence or absence of the dangerous goods license 1 is determined based on whether or not a response command from the dangerous goods license 1 arrives at the data processing circuit 10 via the dangerous goods license reader 24. If NO, the process returns to step 105.
[0049]
In step 160, it is determined whether or not the ID data (driver ID data) stored in the dangerous goods license 1 matches the registered data. The driver ID data is a number or code that is assigned to identify each driver and is different for each driver.
[0050]
Specifically, a data transmission command is sent from the data processing circuit 10 to the dangerous goods license 1 through the communication circuit 11 and the dangerous goods license antenna 18. On the other hand, the ID data is transmitted from the dangerous goods license 1. The ID data is received by the dangerous goods license antenna 18 and sent to the data processing circuit 10 through the communication circuit 11. That is, the ID data is read by the dangerous goods license reader 24 by these processes.
[0051]
Then, the processing circuit 10 determines whether or not the sent ID data matches the ID data stored in the memory 13 (ID data of the dangerous goods handler license holder recorded in advance).
Here, if they match, it is determined that the appropriate dangerous goods license 1 is inserted, and the process proceeds to step 170. On the other hand, if they do not match, it is determined that the appropriate dangerous goods license 1 is not inserted. , Go to Step 260.
[0052]
At step 260 (because the ID data stored in the dangerous goods license 1 is different from that registered in the memory 13), the vehicle management device 2 issues a warning display.
In step 270, the dangerous article license 1 is not appropriate, and the position coordinates of the vehicle (obtained by the communication means described later) are transmitted to the outside by the communication means described later.
[0053]
In step 280, a signal for stopping the engine is sent to the engine ECU 33, the engine is stopped, and the present process is temporarily terminated.
On the other hand, if an affirmative determination is made in step 160, the contents of the dangerous goods license 1 (for example, ID number, owner name, etc.) are displayed on a monitor provided in the driver's seat in step 170.
[0054]
In step 180, the engine can be started (because the proper dangerous goods license 1 has been inserted into the vehicle management device 2 and no signal for prohibiting the engine starting is sent to the engine ECU 33).
In step 190, a signal from a sensor that detects a vehicle state (for example, vehicle drive system abnormality, overweight, vehicle water temperature, oil pressure (for example, brake oil pressure), battery voltage, various state values of dangerous goods) The signal is sent to the data processing circuit 10 through the signal processing circuit 19.
[0055]
In step 200, it is determined whether or not the vehicle state is normal based on a signal from a sensor that detects the vehicle state. Here, if it is determined to be normal, the process proceeds to step 210, and if it is determined to be abnormal, the process proceeds to step 290.
In step 290, the range of abnormality of the vehicle state is verified. That is, based on the signal from the sensor, it is checked how much the vehicle condition is abnormal.
[0056]
In step 300, the fact that the vehicle is abnormal is displayed on a monitor provided in the driver's seat according to the abnormal range.
In step 310, the abnormality of the vehicle and the position coordinates of the vehicle are transmitted to the outside by a communication means described later, and the process proceeds to step 210.
[0057]
On the other hand, if the determination in step 200 is affirmative or if the process proceeds from step 310, in step 210, sensors (tank pressure sensor 5, tank liquid level sensor 6, tank gas sensor) are used to detect the state of the loaded dangerous goods. 7 and the sensor signal from the tank temperature sensor 8) are sent to the data processing circuit 10 through the dangerous substance sensor signal processing circuit 15.
[0058]
In step 220, it is determined based on signals from the sensors 5 to 8 whether or not the state of the load (dangerous goods) is normal. Here, if it is determined to be normal, the process proceeds to step 230.
In step 320, the abnormal range test of the loaded dangerous goods is performed. That is, based on the sensor signal, it is checked how much the load (dangerous goods) is abnormal.
[0059]
In step 330, the fact that the loaded dangerous article is in an abnormal state is displayed on a monitor provided in the driver's seat according to the abnormal range.
In step 340, the state of the loaded dangerous article is abnormal and the vehicle position coordinates are transmitted to the outside by communication means described later, and the process proceeds to step 230.
[0060]
On the other hand, if the determination in step 220 is affirmative or if the process proceeds from step 340, the ID data stored in the dangerous goods license 1 is read again in step 230, and the ID data is registered in the memory 13. Check if it matches.
[0061]
The ID data of the dangerous goods license 1 is checked again here to check whether the dangerous goods license 1 is replaced or the dangerous goods license 1 is not changed. It is to do.
In step 240, based on the check in step 230, it is determined whether or not the dangerous goods license 1 is appropriate (only abnormal). If it is determined that it is appropriate, the process proceeds to step 250, and if it is determined that it is not appropriate, the process proceeds to step 350.
[0062]
In step 350 (because the ID data stored in the dangerous goods license 1 is different from that registered in the memory 13), the warning lamp 35 of the vehicle management device 2 is turned on.
In step 360, the dangerous article license 1 is not appropriate and the position coordinates of the vehicle are communicated to the outside by a method described later.
[0063]
In step 370, a signal for stopping the engine is sent to the engine ECU 33, the engine is stopped, and the process is temporarily terminated.
On the other hand, if an affirmative determination is made in step 240, it is determined in step 250 that the dangerous goods license 1 held by the driver, the state of the vehicle, and the state of the loaded dangerous goods are all normal. To communicate with the outside. Thereafter, the process returns to step 190.
[0064]
That is, steps 190 to 250 are periodically repeated, the dangerous goods license 1, the state of the vehicle, and the state of the loaded dangerous goods are periodically checked, and the result is transmitted to the outside.
f) Next, communication means between the vehicle and the outside in the steps 250, 270, 310, 340, and 360 will be described using the flowchart of FIG.
[0065]
When the communication process is started, in step 400, the position coordinates of the vehicle are determined based on the radio wave received by the GPS antenna 4a.
In step 410, it is determined whether DSRC communication is available for operating the electronic license plate 3. That is, it is determined whether the electronic license plate communication antenna 23 can detect a DSRC radio wave having a predetermined strength or more within a predetermined set time. If it can be detected, the process proceeds to step 450. If it cannot be detected, the process proceeds to step 420.
[0066]
In step 450, since the DSRC communication is possible, the data to be transmitted is transmitted from the electronic license plate antenna 23, and this process is temporarily terminated.
On the other hand, in step 420, it is determined whether or not the telephone can be used. That is, the determination is made based on the strength of the radio wave received by the telephone antenna 4c. Here, if it is determined that it can be used, the process proceeds to step 460, and if it is determined that it cannot be used, the process proceeds to step 430.
[0067]
In step 460, the data to be transmitted is transmitted from the telephone antenna 4c. After the transmission, this process is temporarily terminated.
On the other hand, in step 430, it is determined whether or not satellite communication can be used. That is, the determination is made based on whether or not the intensity of the radio wave entering the satellite communication antenna 4b is sufficiently strong. If it is determined that satellite communication is possible, the process proceeds to step 470. If it is determined that satellite communication is not possible, the process proceeds to step 440.
[0068]
In step 470, the data to be transmitted is transmitted from the satellite communication antenna 4b. It ends after transmission.
On the other hand, in step 440, it is recorded in the memory 13 that communication was impossible (because no communication means could be used).
[0069]
That is, the communication means in the first embodiment can perform communication by any one of communication using the electronic license plate 3, telephone, and satellite communication.
Regarding these communication means, the following can be said.
The contents transmitted by the communication means in the first embodiment are that the dangerous goods license 1 is not appropriate (steps 360 and 270), the vehicle state is abnormal (step 310), and the dangerous substance state is It may be abnormal (step 340), and dangerous goods license 1, vehicle, and dangerous goods are all normal (step 250).
[0070]
・ Communication using the electronic license plate 3 communicates with an antenna installed on the roadside. However, if the contents to be transmitted are recorded in the memory 22 of the electronic license plate 3, the emergency Sometimes it is possible to read from the electronic license plate 3 data concerning the state of the vehicle and the loaded dangerous goods with a data reader such as a handheld reader.
[0071]
The telephone is used to transmit whether or not the dangerous goods license 1 is appropriate in the urban area, the position coordinates of the vehicle, the state of the vehicle, and the state of the loaded dangerous goods.
-Satellite communication is used to transmit whether or not the dangerous goods license 1 is appropriate in a place where the telephone cannot be communicated, the position coordinates of the vehicle, the state of the vehicle, and the state of the loaded dangerous goods. Also, in a city area, when the communication cost of satellite communication is lower than that of a telephone, it can be used instead of a telephone.
[0072]
・ Communication partners include firefighting agencies, local governments, police agencies, and other organizations that need to be notified during transportation, and shippers and dangerous goods transporters who request transportation of dangerous goods.
-Components necessary for communication (for example, for example, to enable communication to the outside even if the driver is in a dangerous state (for example, the state of the dangerous goods loaded is dangerous) and the driver leaves the vehicle) Power is supplied to the communication circuits 12, 17, the data processing circuit 10, the electronic license plate 3, and the sensor signal processing circuit 15).
[0073]
g) With the above-described configuration, the vehicle management device 2 according to the first embodiment has the following effects.
If the vehicle management device 2 of the first embodiment is used, it is possible to prevent a person who does not have the proper dangerous goods license 1 from driving a vehicle loaded with dangerous goods. That is, even if a person who does not have the dangerous goods license 1 is equipped with the vehicle management apparatus 2 of the first embodiment and tries to drive a vehicle loaded with dangerous goods, warning display, engine operation stop, and notification to related organizations are made. Because it is done, you cannot drive.
[0074]
Therefore, by using the vehicle management device 2 of the first embodiment, the safety in transporting dangerous goods is improved.
Further, in the vehicle management device 2 according to the first embodiment, the state of the vehicle and the loaded dangerous goods can be detected by a sensor, and when these are abnormal, the abnormality can be displayed as a warning to the driver. Furthermore, the state of the vehicle and the loaded dangerous goods, and the position coordinates of the vehicle can be communicated to the related organizations by communication.
[0075]
For this reason, it is possible to detect abnormalities in the vehicle and the loaded dangerous goods at an early stage and to take measures to prevent an accident. Furthermore, since the position of the vehicle is also communicated to an external organization, it is useful for taking measures to prevent accidents and taking measures when an accident occurs.
(Example 2)
Next, Example 2 will be described.
[0076]
The configuration of the vehicle management device 52 of the second embodiment is the same as that of the vehicle management device 2 of the first embodiment, and the description of the same parts is omitted.
a) The operation of the vehicle management device 52 of the second embodiment is basically the same as the operation of the vehicle management device 2 of the first embodiment, but the engine operation is stopped even when the dangerous goods license 51 is not appropriate. It is characterized by not being.
[0077]
That is, as shown in the flowcharts of FIGS. 7 and 8, when it is determined in step 560 that the dangerous goods license 51 is not appropriate (for example, the driver ID data stored in the dangerous goods license 51 and the vehicle management device 52 in advance). In the case where the driver ID data stored in No. 1 does not match, warning display (step 660) and communication to the outside (step 670) are performed, but engine operation is not stopped. Thereafter, the routine proceeds to step 580, where the engine is started.
[0078]
Also, if it is determined in step 640 that the dangerous goods license 51 is abnormal, warning display (step 740) and communication to the outside (step 750) are performed, but engine operation is not stopped. Thereafter, the process proceeds to step 590.
Other processes are the same as those in the flowcharts of FIGS.
[0079]
b) The vehicle management device 52 of the second embodiment has the following effects.
In the vehicle management device 52 of the second embodiment, even a person who does not have the dangerous goods license 51 that stores ID data that matches the ID data stored in the vehicle management device 52 can start the engine of the vehicle. And drive the vehicle.
[0080]
Therefore, for example, even when a driver who is different from the plan (who has a dangerous goods handler license but whose ID data is not stored in the vehicle management device 52 of the vehicle) needs to drive the vehicle, Can drive.
As described above, even when a person who does not have ID data stored in the vehicle management device 52 in advance is driving, a person who does not have a dangerous goods handler license because warning display and communication to the outside are performed. Can deter driving vehicles loaded with dangerous goods.
[0081]
Needless to say, the present invention is not limited to the above-described embodiments, and can be implemented in various modes without departing from the scope of the present invention.
(1) For example, the following (1) to (3) can be considered as dangerous goods licenses.
(1) As shown in FIG. 9, there is a magnetic card in which ID data of a dangerous goods handler license holder is magnetically written. As a dangerous goods license reader corresponding to this, for example, there is a reader that reads information written by slitting the magnetic card.
[0082]
(2) For example, there is an IC card with a contact. As a corresponding dangerous goods license reader, for example, there is a reader that inserts the IC card with the contact and reads information from a contact point in contact with the contact.
(3) For example, there is a short distance reading type card. That is, as shown in FIG. 10, the power receiving circuit, the memory, and the communication means are included, and the ID data of the dangerous goods handler license holder is stored in the memory.
[0083]
When this short distance reading type card is brought close to a certain distance from the dangerous goods license reader, the power supply electric wave transmitted from the dangerous goods license reader is received by the power receiving circuit, and the power is recorded in the memory. ID data is transmitted from the communication means.
[0084]
(2) As a warning indication when the dangerous goods license is not appropriate, for example, (a) A communication function is provided to a “danger” mark or the like provided on the outside of the vehicle, and (b) the vehicle A red LED or the like provided outside may blink, and (c) the number plate may be lit (for example, red).
[0085]
(3) As a driver ID, in addition to a type for identifying individual drivers, for example, a type for identifying only whether or not a dangerous goods handler license is available may be used.
For example, the driver ID of a person with a dangerous goods handler license is 1 and the driver ID of a person without the license is 0. If the read driver ID is 0, for example, engine start is prohibited.
[0086]
According to this method, there is an advantage that it is not necessary to input a driver ID of a person who is qualified to drive the vehicle to the dangerous goods license reader.
(4) The vehicle that can use the vehicle management device of the present invention is not limited to a vehicle that uses an internal combustion engine as a power source, and can be used for an electric vehicle and a hybrid vehicle, for example. In that case, as a measure for suppressing the traveling of the vehicle, for example, there is a method of cutting the electric power supplied to the electric motor.
