JPH0863698A - Tracking method for cash transporting trunk - Google Patents

Abstract

PURPOSE: To trace a cash transporting trunk at the time when the cash transporting trunk is stolen by providing the cash transporting trunk with a small-sized transmitter and receiving the radio wave transmitted from the transmitter to obtain information related to the position of the trunk. CONSTITUTION: An extra space is provided in a cash trunk 1 independently of the cash enclosing space, and a small-sized transmitter 2 is set on the wall of this extra space. An antenna 3 may be provided in the trunk 1 or the metal fittings on the outside surface of the trunk 1 may function as the antenna. A radio wave 4 is transmitted from this trunk 1, and the existence position of the trunk 1 is specified based on the radio wave 4. The radio wave 4 is transmitted from beginning to end or carriage or the trunk 1. This transmitted radio wave 4 is received by a patrol car. The patrol car can trace the trunk 1 by the transmission direction of the radio wave 4, and the existence position of the trunk 1 is approximately specified. The radio wave may be transmitted through a satellite for communication for the purpose of preventing jamming due to buildings or the like.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for tracking a cash transport trunk, and when the cash transport trunk is stolen, the position of the trunk is specified so that the case can be quickly resolved. .

[0002]

2. Description of the Related Art When a trunk containing a large amount of cash or important documents is stolen, there is no way to trace it except by the testimonies of the escaped criminals and witnesses regarding the vehicle, and the criminal investigation is too late. There is an inconvenience.

[0003]

SUMMARY OF THE INVENTION In view of the above situation, it is an object of the present invention to provide a method for tracking a cash transport trunk when the cash transport trunk is stolen.

[0004]

In order to achieve the above object, a method of tracking a cash transport trunk according to the present invention is provided with a small transmitter on the cash transport trunk, and receives a radio wave transmitted from the transmitter, Based on the received signal, information about the position of the trunk is obtained.

The invention of claim 2 is characterized in that a small receiver is provided in the cash transport trunk, and the position of the trunk is specified by radio waves received from a plurality of GPS orbiting satellites.

According to a third aspect of the present invention, a small transmitter is provided in the cash transport trunk, and the radio waves transmitted from the transmitter are received by a plurality of distributed sign posts to identify the position of the trunk. It is characterized by doing.

[0007]

With the above-mentioned structure, radio waves are transmitted from the cash transport trunk in the present invention.

[0008]

Embodiments of the present invention will be described below. FIG. 1 shows a schematic diagram of a cash transport trunk (1) which is the object of the tracked object in this embodiment. Inside the trunk (1), a surplus space is provided in addition to the cash enclosed space, and the small transmitter (2) is installed on the wall of the surplus space. The antenna (3) may be provided inside the trunk (1) in the same manner as the small-sized transmitter (2) by providing a dedicated extra space in addition to the cash enclosed space and the installation space for the small-sized transmitter (2). However, as shown in the figure, the metal fitting on the outer surface of the trunk may also have the antenna function. As described above, as the metal fitting, a handle or a belt (particularly, the metal fitting) may be used in addition to the key as illustrated.

In the present invention, under the structure of such a trunk (1), a radio wave (4) is transmitted from this trunk (1), and the position where the trunk (1) exists is based on this radio wave (4). Although it is intended to be identified, the following measures will be taken when a theft occurs.

First, the transmission of the radio wave (4) is started from the beginning of transportation of the trunk (1) and is transmitted until the end of transportation. It is not enough to make a call when an incident occurs. The electric wave (4) transmitted from this trunk (1) is transmitted to the police car as shown in FIG.
Received at (5), depending on the direction of transmission of radio waves (4), a police car
(5) can be traced, and the approximate location of the trunk (1) can be specified. In addition, in order to prevent an obstacle to the radio wave (4) due to a building or the like, the signal may be transmitted via a satellite for communication.

As shown in FIG. 3, the trunk (1) is also provided with a small transmitter (2) and a small receiver (6), and a GPS receiver is provided.
(Global Positioning System
If the orbiting satellites (7) with 6 orbits in the m) system are used, a plurality of radio waves (4) are received from the plurality of satellites (7) and the propagation delay time of each radio wave (4) Information police car
Send to (5), convert to distance information here, trunk (1)
The actual position of can be specified. At present, by using this GPS method, it is possible to detect the position of the detected object with an error of about 10 m.

Further, as shown in FIG. 4, a plurality of sign posts (8) are arranged in a distributed manner, and the radio waves (4) from the trunk (1) are received by each sign post (8), and this sign (8) is received. In the center post (9) that aggregates the posts (8) ..., the propagation delay time of each radio wave (4) is converted into distance information and the trunk
You may use the distributed receiving system which specifies the position of (1).
The position information of the trunk (1) is transmitted from the center post (9) to the police car (5).

The key of the trunk (1) is the trunk
(1) After locking, it is desirable to send it separately. This is because there is a fear that the transmitter (2) in the trunk (1) may be removed or destroyed if the key is robbed.

[0014]

As described above, according to the present invention,
Even if the trunk containing a large amount of cash is stolen, it can be traced by generating radio waves from the trunk, which can greatly contribute to quick resolution of the case.
