The vehicle speed sensor 51 can be provided as an option to the digital speed recorder 10 or as a separate device from the digital speed recorder 10. The engine revolutions sensor (not shown) has a rotating pulse wave for the engine rotation I/F 12B input. The external input I/F 13 is connected to an external device (not shown).

The sensor input I/F 14 is connected to a fuel gauge (fuel gauge) 28, and the input has a value indicating the amount of fuel measured by the fuel gauge 28. A fuel gauge (fuel gauge) 28 detects and displays the amount of fuel stored in the fuel tank tk, and includes a fuel sensor 28A and a fuel gauge 28B. Fuel sensor 28A uses a fuel sender unit. In the fuel gauge sensor unit, the resistance value of the printed resistor is changed by floating up and down in response to the height of the liquid surface. The current value flowing through the printing resistor detects the amount of fuel by the change in the height of the liquid surface. The fuel gauge sensor unit is constituted by a well-known unit such as the above-described floating or linear unit.

The fuel gauge 28B converts the analog signal indicating the amount of fuel output from the fuel sensor 28A into a digital value, indicates the amount of fuel by changing the pointer with respect to the scale, and outputs a representation to the CPU 11 via the sensor input I/F 14.

The external I/F 48 is connected to an external memory device (Storage Memory) 54. The external memory device 54 records the flight attendant data 55, the operation data 56, and the like.

The operation of the operation management system 5 having the above configuration is shown. Figure 2 is a diagram showing the suspicion of fuel theft. When the truck TR is out of the warehouse, it travels according to the scheduled route and stops on the way due to rest or the like. In the meantime, the value of the fuel gauge 28 is gradually reduced in accordance with the travel distance and the like. In the state where the flight attendant stops the engine and the truck TR does not travel, the value of the fuel gauge 28 does not normally change. If the value of the fuel gauge 28 changes in the direction of sudden decrease in the stop of the engine, fuel theft is suspected.

Fig. 3 is a flow chart showing the sequence of fuel measurement operations. This processing is performed by the CPU 11 of the digital speed recorder 10. When the digital speed recorder 10 is activated by the ignition switch being turned on or the like, the CPU 11 first determines whether or not the library button 22z has been pressed, and if the delivery button 22z has been pressed, it is determined that the operation is started (S1). Further, when it is already in the case of the outbound library, the CPU 11 determines in step S1 that the operation is started. Further, regarding the presence or absence of the delivery, it is also possible to determine whether or not the vehicle is actually traveling, without depending on whether or not the exit button is pressed.

After the vehicle is taken out of the warehouse, the CPU 11 waits until the vehicle stops (S2). The stop of the vehicle is determined based on the fact that the speed pulse is no longer output from the speed I/F 12A to the CPU 11. When the vehicle is stopped, for example, due to a rest or the like, the CPU 11 determines whether or not the stabilization time has elapsed after the vehicle is stopped (S3). The stabilization time is a time taken up from the state of the liquid level fluctuation of the fuel in the fuel tank tk immediately after the stop of the vehicle to a state of calmness, and the fuel sensor 28A inserted into the fuel tank tk outputs an appropriate value. It is determined by the time spent. The time taken until the liquid level of the fuel is stabilized varies depending on the amount of fuel, the type of the tank, the capacity of the tank, and the like. Generally, the larger the tank capacity, the longer the time until the height of the liquid level converges.

The CPU 11 discriminates whether or not the vehicle is traveling when the settling time has not elapsed (S4). When the vehicle has started to travel, the CPU 11 ends this action. On the other hand, when the vehicle is not traveling, the CPU 11 returns to the processing of step S3.

When the stabilization time elapses in step S3, the CPU 11 acquires the fuel data from the fuel gauge 28 via the sensor input I/F 14 (S5). At this time, the obtained fuel data is the data after the vehicle has stopped and the stabilization time has elapsed, and is referred to as the fuel data immediately after the stop.

Then, the CPU 11 again acquires the fuel data from the fuel gauge 28 via the sensor input I/F 14 (S6). At this time, the obtained fuel data is the data after the stabilization time, which is called the fuel data for comparison.

The CPU 11 calculates a value (change amount) obtained by subtracting the amount of the fuel data for comparison from the amount of the fuel data immediately after the stop, and determines whether the change in the fuel is large, that is, whether the amount of change in the fuel after the stop is the set value. Above (S7). This set value (threshold value) is used to identify whether it is a value of fuel theft, and can be set to an arbitrary value. For example, in the case where a small amount of fuel theft is foreseen, the set value is set to a value of 1.0 liter to 3.0 liter. On the other hand, when it is foreseen that a large amount of fuel is stolen, it is set to a value of 10 liters to 30 liters.

When the amount of change in fuel after the stop is less than the set value, the CPU 11 judges that it is not fuel theft, and determines whether or not the vehicle has started traveling (S8). When the vehicle has started to travel, the CPU 11 ends this action. On the other hand, when the vehicle is not traveling, the CPU 11 returns to the processing of step S6.

Further, when it is determined in step S7 that the amount of change in fuel after the stop is equal to or greater than the set value, the CPU 11 regards the case as a suspect of fuel theft, and includes information related to fuel theft including warning information (warning signal). Send to the office PC30 (S9). As information related to fuel theft, information such as date (time), location, vehicle number, and amount of fuel change can be cited. Then, the CPU 11 ends this action.

The data related to fuel theft is transmitted to the office PC 30 via the network 70, and is transmitted to the portable terminal 66 via the mobile communication network. In addition, information related to fuel theft can also be notified by mail. When the CPU 31 of the office PC 30 receives the information related to the fuel theft, the emergency information list screen GM (see FIG. 4) of the display unit 33 promptly displays a flag or message indicating that there is a suspect of vehicle theft. In addition, the same display as the office PC 30 can be performed in the portable terminal 66.

The manager of the firm saw the contents of the pop-up display and took the necessary measures for the relevant flight attendants. As a necessary measure, for example, an in-vehicle device such as a digital speed recorder generates an alarm sound, or displays a warning message to a flight attendant's portable terminal, and can also notify the police or the like.

FIG. 4 is a view showing an emergency information list screen GM displayed on the display unit 33. The emergency information list TL is displayed on the emergency information list screen GM. The emergency information list TL registers events in time series. For example, "2016 6/10 10:10:35 emergency", "2016 6/11 07:30:05 puncture", "2016 6/12 13:10:00 over idling time", etc. are registered. Further, the emergency information list screen GM displays a pop-up screen gp including warning information of "XXXX" suspected car theft. In addition, when the pop-up screen gp is displayed, the office PC 30 may issue a "X××× car theft suspect from the speaker 42 when the urgency is high according to the content related to the theft (crime) or the fuel charge (funding). The voice. Moreover, it is also possible to make it easier for the administrator to find out by changing the color in the emergency information list TL or by causing the color to be on and off instead of displaying the pop-up screen gp.

In addition, in the flowchart of FIG. 3, although it is judged whether or not there is fuel theft in the outbound warehouse, it is possible to judge whether or not fuel theft is present in the storage. That is, the CPU 11 can also perform the processing of steps S5 to S9 by omitting the processing of steps S1 to S4, and determine whether or not there is fuel theft in the storage.

In the digital speed recorder 10 of the present embodiment, the vehicle speed sensor 51 (speed detecting means) detects the speed of the vehicle. The fuel gauge 28 (fuel amount detecting means) detects the amount of fuel in the fuel tank tk of the vehicle. When the CPU 11 (transmission means) detects that the speed of the stop of the vehicle is detected and the amount of change in the detected fuel amount is equal to or greater than the threshold value, the communication unit 24 (transmission means) transmits a warning signal to the outside of the vehicle.

In this way, when the fuel is not drastically reduced, the data relating to the fuel theft can be transmitted from the digital speed recorder 10 to the office PC 30, and the intention of the fuel theft is transmitted to the manager of the office. . In particular, by measuring the change in the amount of fuel during the stop, it is possible to improve the accuracy of the determination of the occurrence of fuel theft. The reason for this is that factors such as the change in the amount of fuel caused by the driving conditions and the amount of fuel that cannot be extracted can be excluded. In this way, fuel theft caused by the flight attendant can be reliably found, and the accuracy of the fund management can be improved and the morality of the flight attendant can be improved.

Further, the CPU 11 detects whether or not the vehicle is in the delivery by accepting the pressing of the delivery button 22z (outbound detection unit). The CPU 11 (transmission means) transmits a warning to the office PC 30 (outside the vehicle) when detecting that the speed of the stop of the vehicle is detected and the amount of change in the detected fuel amount is equal to or greater than the threshold value and the vehicle is detected as being out of the warehouse. signal.

In this way, the flight attendant who has performed the fuel theft can be identified by the suspicion of fuel theft in the outbound warehouse. The manager of the firm can take direct action on the specific flight attendant. As a measure taken, for example, an in-vehicle device such as a digital speed recorder generates an alarm sound or displays a warning message to the flight attendant terminal 66, and can also notify the police or the like.

Further, the operation management system 5 (alarm system) is provided with a digital speed recorder 10 (vehicle device) and a office PC 30 (external device) capable of communicating with the digital speed recorder 10 via wireless communication. In the office PC 30, the communication unit 32 (warning receiving means) receives the warning signal from the digital speed recorder 10. The display unit 33 (warning means) presents a warning message indicating that the warning signal has been received.

By displaying the pop-up screen gp including the warning information of "XXXX" in the emergency information list screen GM, the manager of the office can quickly detect fuel theft.

Further, the communication unit 32 (warning information transmitting means) of the office PC 30 transmits the warning information to the preset portable terminal 66 via wireless communication. By transmitting the warning information to the portable terminal 66 held by the flight attendant or the administrator of the office, the flight attendant or the manager of the office can quickly detect that there is a warning message.

Further, the technical scope of the present invention is not limited to the above embodiment. The above embodiment can be accompanied by various modifications, improvements, and the like within the technical scope of the present invention.

For example, although the above embodiment has been described as being applied to a digital speed recorder as a vehicle-mounted device, the present invention can be applied to a dedicated device and a driving record as long as it can detect the stop of the vehicle and can measure the amount of fuel. A drive recorder, a meter device, and an ECU (Engine Control Unit) that performs various controls.
