In order to further improve the present invention, the setting module 10 can also set a distance value between the positioning device 1 and a specific communication device 3, when the AGPS module 13 of the positioning device 1 is positioned to the positioning device 1 and the specific When the distance of the communication device 3 exceeds the set distance value, the current position information is automatically reported to the specific communication device 3.

In addition, the user can also set a time interval through the setting module 10, so that the positioning device automatically returns the current position information to the communication device every time interval.

The positioning device 1 may further include a power detecting device 15 that sends a warning message to the communication device 3 when the power is detected to be too low to remind the user to charge in time.

2 is a flow chart showing the operation of the method for positioning using the positioning device of the present invention.

In step S20, the setting module 10 sets the format of the command message, and the format is as shown in FIG. 3. The command message generally includes five components: an identifier of the sender of the command message, a user ID of the sender, and a sender. The user password 33, the execution content 34, and the recipient's identification code 35. In the preferred embodiment, the identification code 31 of the sender of the command message can be set to "0935123456"; the user ID 32 of the sender is set to "SAM"; the user password 33 of the sender is set to "1234"; The content 34 is set to "Where are you"; the recipient ID 35 is set to "0935654321". If you do not need to change the format of the command message, you only need to set it once.

In step S21, the receiving module 12 receives the short message sent by the communication device 3 through the base station 4.

Step S22, it is identified whether the received short message conforms to the setting format as shown in FIG.

In step S23, when the receiving module 12 receives the command message conforming to the set format, the AGPS module 13 is turned on, and the current position of the positioning device 1 is positioned to obtain current position information. The specific working principle of the AGPS module 13 is as described above.

In step S24, the data returning module 14 reports the information of the current location of the positioning device 1 to the communication device 3 in the form of a short message.

In the step S22, when the received short message does not conform to the setting format, step S25 is performed to delete the received short message.

FIG. 3 is a schematic diagram showing the format of a command message of the present invention. The command message substantially includes five components: an identification code 31 of the sender of the command message, a user ID 32 of the sender, a user password 33 of the sender, an execution content 34, and an identifier 35 of the recipient.

The positioning device 1 has a simple structure, so that an electronic device having a very small volume can be built in some decorations or the like. After receiving the command message, the current location information of the positioning device 1 can be reported in time to facilitate the user to find the location of the person or item carrying the positioning device 1. The present invention therefore provides a simple and convenient way of tracing people/objects.
