Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a load theft prevention device for an automobile that carries a load.
[0002]
[Prior art]
In general, in the case of an automobile that carries luggage such as a parcel delivery service or a truck service, the load is often stolen when the driver leaves the automobile for delivery, collection or rest of the luggage. If the driver performs the closing and locking of all doors when leaving the car, there is little risk of theft. However, when loading and unloading cargo frequently, it is very troublesome to close the door, insert the key, and lock each time. This is a factor that prevents all doors from being locked and theft of cargo.
[0003]
For this reason, recently, a system has been developed in which the door is automatically locked when the door is closed without performing operations such as inserting and removing a key, and the lock is released by a signal transmitter held by the driver.
[0004]
[Problems to be solved by the invention]
If this method is adopted, the driver only needs to close the door when leaving the car, and it is freed from the hassle of key operation, so all doors can be locked and the risk of cargo theft occurring Decrease significantly.
However, this method prevents theft of the load by an outsider, and is ineffective for theft of the load involving the insider, that is, the crew (including the driver).
[0005]
An object of the present invention is to provide a load theft prevention device that prevents theft of a load by an outside person and also makes it difficult for the crew to be involved in theft of the load.
[0006]
[Means for Solving the Problems]
In order to achieve this object, the cargo theft prevention device according to the invention of claim 1 includes an ID tag that records a crew member's ID (personal identification) number, and an ID tag that is installed at a predetermined position of an automobile and transmits radio waves to the ID tag. An antenna for receiving the number, a registration means for registering the ID number, a contrast means for comparing the ID number received by the antenna and the registered ID number, and automatically when all the doors of the vehicle are closed Locking means for locking all doors, unlocking means for unlocking at least one door of an automobile only when the ID number comparison by the comparison means matches, and door opening / closing signals for inputting opening / closing signals of all doors An input means, a clock unit, a GPS receiver for detecting the position of the automobile, and a recording device. When operating the automobile, at least an ID registered in the recording device No. and the the door of the loading space is open, and to record the time and location of the vehicle when the door of the loading space is open, it is characterized in.
[0007]
In this way, when all the doors of the car are closed, all the doors are automatically locked, and the doors will not open unless the ID tag number possessed by the crew member matches the ID number registered in the car. Therefore, it is possible to prevent the cargo from being stolen by outsiders.
The recording device records the ID number of the crew member (usually the driver) of the car, the opening of the luggage compartment door, and the time and position (location) at that time, so there was later theft. When it turns out, at that point the record can be contrasted with the actual package collection and delivery record. The crew is involved in theft if the luggage compartment door is opened at a location unrelated to the actual package collection destination or the luggage compartment door is not opened at the package delivery destination. It can be estimated that the possibility is high. Also, the fact that the time and position when opening the luggage compartment door with the crew of the car is recorded means that the crew should open the luggage compartment door at a place unrelated to the delivery destination of the luggage. Therefore, it has the effect of deterring crew members from being involved in theft.
[0008]
Next, the invention of claim 2 is the load anti-theft device as described above, wherein the recording device is composed of a memory card read / write device and a memory card. A memory card is inserted into the memory card, and at least the registered ID number, the opening of the luggage compartment door, the time when the luggage compartment door was opened, and the position of the car are recorded on the memory card. It is what I did.
In this way, when the car departs from the base (such as a truck terminal), the crew member has the ID tag and the memory card, and when returning, the ID tag and the memory card are collected and the memory card is recorded. By transferring it to the computer, it is possible to easily conduct later investigation and analysis.
[0009]
Next, the invention according to claim 3 further includes a wireless communication unit capable of transmitting data to the base station in the cargo theft prevention device as described above, and transmits data to be recorded in the recording device to the base station in real time. It is what you do.
If it does in this way, it will become possible to grasp the operation situation of the car in real time in a base station. In particular, if a display device that displays a map is installed at the base station and the position of the car is displayed on the map based on the position information sent from the car, the operation status of the car can be grasped. Becomes easier.
[0010]
According to a fourth aspect of the present invention, in the load antitheft device as described above, the vehicle further includes means for inputting at least one of a travel distance, a travel speed, and an engine speed of the automobile, Such data is recorded.
If it does in this way, it will become possible to grasp the operation situation of a car more correctly.
[0011]
Next, when the recording device comprises a memory card read / write device and a memory card, the invention of claim 5 is further provided with a display device for displaying a map, and the collection and delivery of the day is preliminarily stored on the memory card before departure. The destination is recorded, the recorded collection / delivery destination is read by a memory card read / write device, and displayed on the display device together with the map.
In this way, it is possible to operate while confirming the delivery destination and collection destination displayed on the display device in the car on the map, so that efficient collection and delivery operations can be performed, and even those who are not familiar with geography can collect and deliver Can be performed. In addition, since the collection and delivery destinations are set in advance, there is a function of preventing the crew from going to a place off the collection and delivery route, which is also effective in preventing the crew from being involved in theft.
[0012]
Next, the invention of claim 6 registers an ID tag in which an ID number of a crew member is recorded, an antenna that is installed at a predetermined position of an automobile and transmits an electric wave to the ID tag to receive the ID number, and the ID number is registered. Registering means for comparing the ID number received by the antenna with the registered ID number, locking means for automatically locking all the doors when all the doors of the automobile are closed, and the comparing means The unlocking means for unlocking at least one door of the automobile, the door opening / closing detection means for detecting the opening / closing signal of all the doors, the clock section, and the position of the automobile are detected only when the ID number comparison by A GPS receiver and a wireless communication unit that transmits data to the base station are provided in the automobile, and a recording device that records data transmitted from the automobile is provided in the base station, from the automobile to the base station. At least the registered ID number, the opening of the luggage compartment door, the time when the luggage compartment door was opened, and the data on the position of the vehicle are transmitted. .
In this way, it is possible to obtain the same effects as those of the first aspect of the invention without providing a recording device in the automobile.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0014]
Embodiment 1

Although not shown in the figure, the mode changeover switch can select either a registration mode for registering an ID number or an operation mode for preventing cargo theft.
[0015]
Further, the ID number of the ID tag 7 possessed by the driver (the individual number of the driver) is input to the control unit 3 through the ID antenna 9 and the transceiver 11. An IC chip in which an ID number is recorded is incorporated in the ID tag 7. When the ID tag 7 is supplied with electric power from the ID antenna 9 by radio waves, the ID tag 7 transmits the ID number recorded therein to the ID antenna 9. The transceiver 11 controls transmission / reception of radio waves between the ID tag 7 and the ID antenna 9.
[0016]
The control unit 3 includes registration means for registering the input ID number, and contrast means for comparing the registered ID number with the ID number input thereafter. In addition, the control unit 3 detects the lock signal generation means for generating a signal for locking all the doors when all the doors of the automobile are closed, and at least one door of the automobile only when the ID number comparison by the comparison means matches. Unlocking signal generating means for generating a signal for releasing the lock. Further, the control unit 3 includes door opening / closing signal input means for inputting opening / closing signals of all doors.
[0017]

Further, a memory card read / write device 19 is connected to the control unit 3 so that data can be written to a memory card 21 inserted in the device 19 and data recorded on the memory card 21 can be read. It has become.
[0018]
FIG. 2 shows the position of each part of the apparatus of FIG. 1 attached to the automobile (truck). The apparatus main body 1 is installed in the cab 23. There are two ID antennas 9 in this example, one is attached to the windshield of the cab 23 and the other is attached to the rear door of the luggage compartment 25. The GPS antenna 13 is attached on the roof of the luggage compartment 25 or the like. In FIG. 2, 27A and 27B are locking devices for the door of the cab 23, and 28 is a locking device for the door of the luggage compartment 27. The lock devices 27A, 27B, 28 are constituted by an electromagnetic drive device, a motor, a pneumatic cylinder, or the like.
[0019]
Next, the operation of this apparatus will be described with reference to FIGS. FIG. 3 is a flowchart of ID number registration, and FIG. 4 is a flowchart of theft prevention operation. The driver receives the car key, the ID tag 7 and the memory card 21 when starting the business of the day. An ID number of the driver is recorded on the ID tag 7. The ID tag 7 is preferably attached to the wrist like a wristwatch.
[0020]
The driver first opens the door of the automobile with the key, and turns on a power switch (not shown) of this apparatus in S01 of FIG. 3 (meaning of step 01, the same applies hereinafter). It is preferable that the power supply is automatically turned on when the key is inserted into the keyhole and turned to ACC. However, in order to simplify the explanation here, when the power switch is turned on, the work of the day is over and the power supply is turned on. It is assumed that the operation of this device is continued until the switch is turned off (if the power is automatically turned on by ACC, it is sufficient to operate a timer so that the power does not turn off when the key is removed midway. ).
[0021]
When the power is turned on, the control unit 3 confirms the state of the mode switch in S02. If the mode switch is in the operation mode, a signal requesting the driver to switch to the registration mode is issued in S03. When the mode change switch is in the registration mode, input of an ID number is awaited in S04. The ID number can be easily input by holding the ID tag 7 over the ID antenna 7. If no ID number is input, a signal requesting the driver to input the ID number is issued in S05. When the ID number is input, the control unit 3 registers the ID number in S06. If an ID number has already been registered, the ID number is registered after erasing it. When there are a plurality of crew members, a plurality of ID numbers can be registered.
[0022]
Next, the control unit 3 confirms whether or not the memory card 21 is inserted in the memory card read / write device 19 in S07. If the memory card 21 is not inserted, a signal requesting the driver to insert the memory card 21 is issued in S08. When the memory card 21 is inserted, the ID number is written to the memory card 21 in S09.
[0023]
Thereafter, the control unit 3 confirms the state of the mode switch again in S10, and when the mode switch is in the registration mode, issues a signal requesting the driver to switch to the operation mode in S11. When the mode changeover switch is in the operation mode, a signal for turning on the starter relay of the automobile is issued in S12. When the starter relay is turned on, the engine can be started by turning the key in S13. The starter relay on is a condition for starting the engine, and the engine cannot be started when the starter relay is off.
[0024]
In the above description, the mode switch is described as being manually switched. However, the mode switch is automatically switched after confirming whether or not the ID number is registered and writing the ID number to the memory card. You can also
[0025]
After the engine is started in S13, the process proceeds to the flowchart of FIG. When the engine is started, the control unit 3 confirms whether or not all the doors of the automobile are closed in S14. This confirmation is performed by taking the logical sum of the closing signals of the door opening / closing detection sensors installed in each door. When even one door is open, a signal is issued to request the driver to close the door in S15. When all the doors are closed, the control unit 3 issues a locking signal for locking all the doors in S16. This locks all doors. That is, in this apparatus, when all the doors are closed, all the doors are automatically locked. Therefore, the driver does not need to lock the door with the key.
[0026]
When leaving the base in this state, arriving at the destination and opening the door, the driver may hold the ID tag 7 over the ID antenna 9 in the vehicle. Then, the control unit 3 detects the ID tag in S17, inputs the ID number in S18, and collates the ID number input in S19 with the registered ID number. If the ID numbers do not match in this verification, the process returns to S17. When the ID numbers match, an unlock signal is issued in S20. When the unlock signal is issued, the door corresponding to the ID antenna 9 with the ID tag 7 held (in this case, the cab door) is unlocked, so that the door can be opened by hand.
[0027]
When the door is opened, a door opening signal is input from the door opening / closing sensor to the control unit 3 in S21. Then, in S22, the control unit 3 inputs the time at that time from the clock unit 17 and writes it in the memory card 21, and also inputs the position of the car at that time from the GPS receiver 15 and writes it in the memory card 21, A process of writing to the memory card 21 that the door is opened.
[0028]
When the driver is in the cab 23, the lock can be manually released without using the ID tag. In that case, since the door is opened without detecting the ID tag in S17, it is detected in S23 that the door is opened. When the door open signal is received in S23, the process proceeds to S22 and the above-described processing is performed. When the door open signal is not received (when the door is not opened), the process returns to S17.
[0029]
When the process of S22 is completed, the control unit 3 returns to S15 and issues a signal requesting the driver to close the door. When the driver gets out of the car and closes the doors, the doors are locked again through S14 and S16. Thereafter, when the driver opens the door of the luggage compartment in order to drop the luggage, the ID tag 7 may be held over the ID antenna 9 installed in the door of the luggage compartment. Then, the door of the luggage compartment 25 is unlocked through the processes of S17 to S20. When the door of the luggage compartment 25 is opened, the signal is input in S21, and the time, position, and opening of the luggage compartment door are written in the memory card in S22.
[0030]
After the luggage is unloaded, when the luggage compartment door is closed, all doors are locked again through S14 and S16. Thereafter, when the delivered luggage is delivered and the collected luggage is loaded, the door is unlocked by holding the ID tag over the ID antenna of the luggage room, the door is opened, and the luggage is loaded. At this time, the memory card also records the time, position, and opening of the luggage compartment door. Thereafter, when the luggage compartment door is closed, all the doors are locked as described above. Thereafter, when entering the cab, the door is unlocked by holding the ID tag over the ID antenna of the cab and the door is opened. Also at this time, the time, position, and the opening of the cab door are recorded on the memory card. When the cab door is closed, all the doors are locked as described above. In this state, head to the next destination.
[0031]
As described above, in this load theft prevention device, all doors are automatically locked when the opened door is closed, so there is no possibility that the load will be stolen unless the door is left open. When the door is open, a signal requesting that the door be closed is issued, so that it is almost impossible to forget to close the door.
[0032]
In addition, since the driver's ID number and the time and position when the door is opened are recorded in the memory card, if the memory card is collected and the recorded content is read out, for example, an operation record as shown in FIG. 5 is obtained. be able to. In addition, when reading the position information of the GPS receiver recorded on the memory card, it is preferable to read it by converting it into place name address information corresponding to the map information.
[0033]
If the operation record as shown in FIG. 5 is left, when it is later determined that the luggage is lost, the actual collection / delivery record of the luggage can be matched with the time and place when the door is opened. The crew is involved in theft if the luggage compartment door is opened at a location unrelated to the actual package collection destination or the luggage compartment door is not opened at the package delivery destination. It can be estimated that the possibility is high. Also, the fact that the time and position when opening the luggage compartment door with the crew of the car is recorded means that the crew should open the luggage compartment door at a place unrelated to the delivery destination of the luggage. Therefore, the crew is less likely to be involved in the theft, which is effective in preventing theft involving the crew.
