Figure 2 is a configuration of the position reporting terminal 2 used in the present invention, such as a synthetic resin material, the radio call transmission unit (pagers) having a minimum function with excellent reception rate inside the case through which radio waves can pass through; By combining the city phone 6 which can transmit data while communicating wirelessly with a nearby city phone base station, a small location reporting terminal 2 which can be secretly installed in the vehicle can be configured to check the position of the vehicle.

In the present invention, the wireless pager 4 having a unique identification number only needs to receive a positioning call signal, and the city phone 6 also has only the city number base station and the alarm code data necessary for the location confirmation of the vehicle. ), So that unnecessary call functions (audio functions), display functions, alarm functions, text service functions, vibration functions, selection functions, audio functions, etc. are removed, and the city phone 8 receives control signals from the wireless call receiving unit. Maintain the standby state until the power consumption and volume can be reduced.

That is, in the case of the city phone 6 constituting a part of the location reporting terminal 2 of the present invention, since it is a means for transmitting data such as a vehicle number and an alarm code wirelessly by request (calling), not by a voice call purpose, a minimum need is required. Functions such as a wireless link setting unit for transmitting and receiving data by establishing a wireless link with the city phone base station 8, a storage device for storing a vehicle number and an alarm code, and various data (vehicle number and alarm code) as a radio wave Unnecessary functions other than the local oscillator and the modulator can be removed to reduce power consumption and volume. Also, if a call signal (positioning signal) is not input to the position reporting terminal 2, the standby state is performed with minimal power. To reduce power consumption.

In addition, a storage device having a data input unit is connected to one end of the position reporting terminal 2 so that the vehicle number and the alarm code can be stored, and the storage device can freely write or erase data (which can be modified) and is nonvolatile. Use a semiconductor memory having a.

In the above, the alarm code is for identifying the call code or the alarm code in the city phone base station 8, and when the alarm code is sent, the city phone base station 8 recognizes the alarm state for positioning rather than the call state and signals the signal. To deal with.

Using the data input unit, the alarm code and the location report terminal 2 can be stored by inputting the vehicle number of the vehicle installed.

In the present invention, the power source for operating the location reporting terminal 2 may be used by introducing the power of the vehicle, but because it is likely to be detected by criminals, but to use its own battery, so that it can be replaced periodically, the battery uses a small By greatly reducing the volume of the location reporting terminal (2), the installation is easy to stand out.

When the radio link is established between the city phone 6 and the city phone base station 8, the vehicle number and the alarm code data stored in the storage device of the location reporting terminal 2 are transmitted to the city phone base station 8, and the data is completed. Is disconnected, and at the same time as the disconnection of the radio link, the city phone base station 8 attempts to connect with the city phone base station management apparatus 10, and when the connection is established, the I phone owns the city phone base station 8 itself in addition to the vehicle number and alarm code data. The D is transmitted together, and the city phone base station management apparatus 10 transmits the vehicle number, the alarm code, and the position information (order) according to the city phone base station I and D to the management server (SEVER) 18.

Therefore, the management server 18 can quickly determine the current position of the vehicle (movement position and stop position of the vehicle), thereby finding the stolen vehicle early, and blocking the use early for crimes. .

The location of the stolen vehicle can be determined by inquiring an address according to the city phone base station I.D using a database built on the management server 18 itself or a database built on the city phone base station management apparatus 10.

In the present invention, the wireless call receiving unit for receiving the call signal has excellent reception rate since the existing pagers with excellent reception rate are applied, and the city phone 6 which transmits the vehicle number and the alarm code has a dot structure on the element of the city. In addition to being associated with numerous city phone base stations 8 scattered, the radius of communication is very narrow around 150m, so that the current and moving positions of vehicles can be checked and tracked in the form of dots. When the call signal for tracking is periodically transmitted, the location report signal is periodically transmitted from the location reporting terminal 2 mounted on the vehicle, so that the moving position of the stolen vehicle can be continuously and continuously detected, so that the user can quickly and easily take action.

In the present invention, the management server 18 and the general subscriber telephone may be linked to each other to provide a stolen vehicle positioning service for a general telephone (or wireless telephone) subscriber.

The object to which the location reporting terminal of the present invention can be applied is not only a vehicle but also an object that can be moved arbitrarily or arbitrarily, for example, Miana, a probation officer, a mentally or physically inconvenient person, an animal, valuables, or a location of various objects. It may be used for tracking or identifying a movement route, and its effect may be identified as well.

As described above, the present invention can quickly identify the current location of the stolen vehicle so as to prevent a criminal from being caught by using a location reporting terminal composed of a pager and a city phone (CT-phone) having excellent reception rate. The vehicle is prevented from being used for the purpose of crime or the like.
