Reference numeral 9 denotes a car navigation (navigation means) that sets a destination based on unlocked position information received by the wireless communication device 3 and searches for and displays a route to the destination. The vehicle speed sensor 11 measures the infrared sensor for detecting the presence of a person in the loading platform, and the door opening sensor 12 detects the opening state of the loading platform door.
FIG. 2 is a flowchart showing the operation of the security system according to the first embodiment of the present invention.
[0024]
Next, the operation will be described.
First, the center device 1 registers a destination for collecting and delivering packages (a location that permits unlocking of the loading platform key, including the location of customers and sales offices), the driver's name, and the vehicle number. Then, the unlock position information indicating the destination is transmitted via the communication satellite or the Internet communication network (step ST1).
The unlock position information indicates a peripheral area centered on the destination in consideration of an error of the position detection device 4. In general, the error generation range is several tens to several hundreds of meters.
[0025]
The wireless communication device 3 mounted on the truck 2 receives the unlock position information transmitted from the center device 1 (step ST2).
When the radio communication device 3 receives the unlock position information, the car navigation 9 sets a destination based on the unlock position information, searches for a route to the destination, and displays the route on the display. Displayed (step ST3).
[0026]
When the truck 2 starts traveling on the route toward the destination, the information processing device 6 sequentially compares the unlocked position information received by the wireless communication device 3 and the current position information output from the position detecting device 4. (Steps ST4 and ST5).
That is, it is determined whether or not the current position is included in the peripheral area indicated by the unlock position information.
[0027]
If the current position is not included in the peripheral area indicated by the unlocking position information, even if the unlocking operation device 5 is operated to unlock the key, it is output from the unlocking operation device 5. The unlock command is invalidated (steps ST6 and ST7).
On the other hand, when the current position is included in the peripheral area indicated by the unlock position information, the key unlock operation by the unlock operation device 5 is validated. Therefore, when unlocking of the key is operated by the unlocking operation device 5, an unlocking command output from the unlocking operation device 5 is output to the electronic locking device 8 via the external device control device 7 (step ST6, ST6). ST8).
[0028]
When receiving the unlocking instruction via the external device control device 7, the electronic locking device 8 unlocks the door key (step ST9).
[0029]
As apparent from the above, according to the first embodiment, the unlocking operation is performed only when the unlocked position information received by the wireless communication device 3 matches the current position information output from the position detecting device 4. Since the operation of the device 5 is configured to be effective, the door unlocking is permitted only at the destination. Therefore, there is an effect that it is possible to reliably prevent theft and falsification of the package being transported.
In addition, since it is not necessary for the center apparatus 1 and the radio | wireless communication apparatus 3 to implement radio | wireless communication in the destination, the collection and delivery of a luggage | load can be performed also in the underground parking lot where communication is impossible, for example. Moreover, since a password is not required, there is no problem that a password is known to a third party.
[0030]
Embodiment 2. FIG.
In the first embodiment, the operation of the unlocking operation device 5 is enabled only when the unlocked position information received by the wireless communication device 3 and the current position information output from the position detecting device 4 match. As shown in FIG. 3, when the center device 1 transmits unlocking time information indicating the time at which the key unlocking is permitted (step ST11), the wireless communication device 3 unlocks the unlocking time information. Is received (step ST12).
[0031]
Then, the information processing device 6 sequentially compares the unlock time information received by the wireless communication device 3 with the current time information output from the position detection device 4 (steps ST14 and ST15), and only when both match. You may make it validate operation of the unlocking operation apparatus 5. FIG.
In addition, when the unlocking time information is composed of a time to start unlocking permission and a time to end permission, it is determined whether or not the current time information is included in the unlocking time information.
[0032]
Embodiment 3 FIG.
In the first embodiment, in order to permit the unlocking of the key, the condition that the unlock position information matches the current position information is a condition. In the second embodiment, the condition that the unlock time information matches the current time information is a condition. However, you may make it a condition to make both coincidence.
As a result, the unlocking of the key is not permitted unless both the unlocking position and the unlocking time coincide with each other, so that it is possible to more reliably prevent theft or falsification of the package being transported.
[0033]
Embodiment 4 FIG.
In the first embodiment, etc., only when the unlocked position information received by the wireless communication device 3 matches the current position information output from the position detecting device 4, the operation of the unlocking operation device 5 is validated. As shown, the information processing device 6 transmits a warning message to the center device 1 when the key is unlocked even though the unlocking command output from the unlocking operation device 5 is invalidated. You may do it.
[0034]
That is, when the information processing device 6 invalidates the unlocking command output from the unlocking operation device 5, when the door opening sensor 12 detects the open state of the door of the loading platform, or from the unlocking operation device 5. When the unlocking command is not output, if the door opening sensor 12 detects the opening state of the loading platform door, the information processing device 6 constituting the warning means indicates a warning indicating abnormal door opening via the wireless communication device 3. A message is transmitted to the center apparatus 1.
As a result, there is an effect that the supervisor can recognize the possibility of the occurrence of the accident.
[0035]
Embodiment 5 FIG.
In the fourth embodiment, a warning message is transmitted to the center device 1 when the key is unlocked even though the information processing device 6 invalidates the unlock command output from the unlock operation device 5. Although what was shown was shown, you may make it transmit a warning message to the center apparatus 1, if a vehicle starts driving | running | working in the state in which the key is unlocked.
[0036]
That is, when the door opening sensor 12 detects the opening state of the loading platform door or when the electronic locking device 8 is unlocking the door key, the vehicle speed sensor 10 detects the traveling of the truck 2. Alternatively, when it is detected that the current position coordinates are outside the area where unlocking is permitted, the information processing device 6 constituting the warning means sends a warning message indicating the door opening travel via the wireless communication device 3 to the center device. 1 may be transmitted. Further, the warning message may be displayed on the display in the track 2 or a warning sound may be issued.
[0037]
In particular, when amusement equipment is transported, it is necessary to prevent people from getting into the vehicle during transportation in order to prevent tampering of the control device of the equipment. Therefore, after a door is normally opened at a specific destination, it is necessary to move the truck 2 to another place with the door opened to prevent a person from getting on the loading platform.
According to the fifth embodiment, since it can be recognized that the vehicle is traveling with the door of the loading platform opened, tampering of the amusement device can be prevented.
[0038]
Embodiment 6 FIG.
In the above-described fifth embodiment, when the vehicle starts running with the key unlocked, a warning message is transmitted to the center device 1. However, in a place other than the place where the key is allowed to be unlocked. When the truck 2 is stopped for a predetermined time or longer, a warning message may be transmitted to the center device 1.
[0039]
That is, when the information processing device 6 constituting the warning means does not detect the coincidence of the unlocked position information and the current position information, if the vehicle speed sensor 10 detects the stop of the truck 2 for a predetermined time or longer, the wireless communication A warning message indicating that the vehicle has stopped for a long time may be transmitted to the center device 1 via the device 3.
As a result, there is an effect that the supervisor can recognize the possibility of the occurrence of the accident.
[0040]
Embodiment 7 FIG.
In the above-described sixth embodiment, a case where a warning message is transmitted to the center apparatus 1 when the truck 2 has stopped for a predetermined time or longer in a place other than the place where the key is allowed to be unlocked is shown. A warning message may be transmitted to the center device 1 when it is detected that a person has entered the loading platform during the travel of the vehicle.
[0041]
In other words, when the vehicle speed sensor 10 detects the traveling of the truck 2, if the infrared sensor 11 detects that a person is present on the loading platform, the information processing device 6 constituting the warning means passes through the wireless communication device 3. Thus, a warning message indicating human detection is transmitted to the center apparatus 1.
As a result, there is an effect that the supervisor can recognize the possibility of falsification of the luggage.
[0042]
Embodiment 8 FIG.
In the second embodiment, only when the unlocking time information received by the wireless communication device 3 matches the current time information output from the position detecting device 4, the operation of the unlocking operation device 5 is validated. However, if the arrival time of the truck 2 is predicted to determine whether or not it can arrive by the scheduled time, and if it is determined that the arrival is difficult, a warning message is transmitted to the center device 1. It may be.
[0043]
That is, the information processing device 6 constituting the warning means is measured by the average moving speed obtained from the position information of the vehicle moved per unit time from the current position information output from the vehicle speed sensor 10 or the position detecting device 4. The arrival time of the track 2 is predicted from the average speed of the track 2, the current position information output from the position detection device 4, and the unlocked position information received by the wireless communication device 3.
Then, the information processing device 6 compares the predicted arrival time with the scheduled time to determine whether the arrival is possible by the scheduled time. When determining that the arrival is difficult, the information processing device 6 The warning message indicating arrival difficulty is transmitted to the center apparatus 1 through the center apparatus 1.
Thereby, there is an effect that the supervisor can recognize that the arrival is delayed in advance. Therefore, it is possible to take advance measures such as dispatching another truck if possible.
[0044]
In addition, although it is the start timing of the estimated arrival time calculated by the information processing device 6, in consideration of the distance from the departure place to the destination in advance, the detection time that can be handled in advance is calculated backward from the estimated arrival time, When the detection time comes, the calculation of the estimated arrival time is started.
[0045]
Embodiment 9 FIG.
In the first to eighth embodiments described above, the center device 1 transmits the unlocked position information indicating the registered destination, but the destination registration is often manually input. However, when there are many destinations, the load on the operator is great, so the operator inputs only the name of the area such as the city name into the center apparatus 1, and the center apparatus 1 stores the address book data (the area such as the city name). The area name is automatically converted into coordinate data using map data having a name.
[0046]
This greatly reduces the load compared to the case where the operator directly inputs the unlocking position information, but the error of the unlocking position information may increase (there may be no street address or street name in some areas). May be accompanied by large errors).
[0047]
Therefore, in the ninth embodiment, when the unlock position information is coordinate data automatically converted based on the address book data, the center device 1 is the coordinate data automatically converted into the unlock position information. Is transmitted with an identification flag indicating.
When the identification flag is added to the unlocking position information received by the wireless communication device 3, the information processing device 6 is an area where the key can be unlocked (centering on the destination shown in the first embodiment). (Peripheral area) is made wider than in the first to eighth embodiments.
As a result, even when the unlock position information has a large error, the key can be reliably unlocked at the destination.
[0048]
When the door key is unlocked, the information processing device 6 transmits current position information indicating the current position to the center device 1 via the wireless communication device 3.
When the center device 1 receives the current position information, the center device 1 replaces the current position information with the unlocked position information, and transmits the unlocked position information the next time the package is transported to the same destination. The identification flag is not added to the unlock position information.
[0049]
Embodiment 10 FIG.
Although not particularly mentioned in the first to ninth embodiments, recording of a recording device (not shown) for monitoring a suspicious person is normally started when the ACC power supply (accessory power supply) of the track 2 is turned on. To do.
However, in this case, since the recording state becomes long, the usage amount of the recording medium (recording tape) increases, and it takes a long time to search for a recording point when a problem occurs. In addition, there is a concern about the deterioration (lifetime) of the recording device and the recording medium.
[0050]
Therefore, in the tenth embodiment, when the sensor attached to the truck 2 detects an abnormality (for example, when the infrared sensor 11 detects the presence of a person in the loading platform, or when the door open sensor 12 is in the door open state) Or when a door breakage is detected), the recording device starts recording.
As a result, it is possible to record only during a period during which suspicious activity may be taking place. As a result, the amount of recording media used can be reduced, and the recording point at the time of the problem can be easily searched. Can do. In addition, the service life can be improved.
[0051]
Embodiment 11 FIG.
In Embodiment 10 described above, the recording apparatus starts recording when the sensor attached to the track 2 detects an abnormality. However, when the unlocking operation of the key by the unlocking operation apparatus 5 is performed, The recording device may start recording. As a result, it is possible to record only during a period during which suspicious activity may be taking place. As a result, the amount of recording media used can be reduced, and the recording point at the time of the problem can be easily searched. Can do. In addition, the service life can be improved.
[0052]
However, even if the recording device is turned on, the recording is not started immediately and the standby state is set for several seconds. Therefore, the suspicious behavior in the standby state may not be recorded.
Therefore, the information processing device 6 does not permit the unlocking of the key until the recording by the recording device actually starts. That is, the unlocking of the key is not permitted in the standby state.
Thereby, there exists an effect which can record a suspicious act reliably.
[0053]
