The Global Positioning System (GPS) is a radio positioning network based on space technology that can provide users with suitable receivers with information about location, speed, date, direction, altitude, and specific information quality. The Global Positioning System was developed by the U.S. Department of Defense. The space part of the system consists of a set of global positioning satellites orbiting the earth in a 12-hour non-synchronous orbit. Since it is currently open to the public, countless devices using GPS have been put into the commercial market.

The personal global positioning system can keep climbers from getting lost in complex terrain. The navigational global positioning system has been used for many years and is now being widely used on recreational and commercial ships.

As shown in Figure 2, according to the embodiment of the present creation, the process of transmitting location data from the location reporting phone to the communication system is disclosed. The process includes the following steps:

(1) Connect the radio frequency transceiver 20 to a communication system to communicate with the network;

(2) Activate the position acquisition control device 30, the data management unit 60, the data conversion device 70, and the baseband audio signal processing device 80 to encode the position data and/or identification signal into the baseband signal, and then modulate the radio frequency carrier to generate the encoded RF position signal;

(3) Start the radio frequency transceiver 20 to transmit the encoded radio frequency position signal to the communication system.

In step (1), the radio frequency transceiver 20 is located in the geographic area covered by a specific communication system, so the position reporting interphone can be connected to the specific communication system by activating the radio frequency transceiver 20. When the connection with the communication system is established, the radio frequency transceiver 20 can broadcast the user's voice information and broadcast the encoded radio frequency position signal (for example, including the position report of the interphone and/or the identification signal).

In step (2), according to an embodiment of the present creation, the position acquisition control device 30 is activated when the communication trigger circuit element 13 in the speaker-microphone device 10 is triggered. In one embodiment, the voice information input by the user through the speaker-microphone device 10 and a certain amount of location information (for example, GPS positioning data) are performed in the aforementioned manner (for example, attach, pre-attach, superimpose) Merge into a coded speech/location baseband signal. In one embodiment, the recognition signal is also combined into a voice/location/recognition baseband signal. One of the functions of the identification signal is to identify a specific microphone when multiple position reporting phones are connected to a communication system at the same time. The combination of voice, location and identification signals is accomplished by the data management unit 60, the data conversion device 70, and the baseband audio signal processing device 80, using well-known technologies. Then the encoded voice/location baseband signal (or voice/location/recognition baseband signal) is converted (that is, modulated with the carrier) into a radio frequency location signal.

In an embodiment, the position acquisition control device 30 (for example, a global positioning system controller) is configured to automatically start receiving the position signal in step (2) for a period of time. In one embodiment, the user sets the position acquisition control device 30 to receive the position signal every 10 minutes. In this embodiment, after the radio frequency position signal is encoded and converted, no matter whether the speaker-microphone device 10 receives the voice signal, the radio frequency transceiver 20 is ready to transmit the radio frequency position signal to the communication system.

In another embodiment, the location acquisition control device 30 is configured to be activated only when a request from the communication system is received. In this embodiment, the communication system sends a request signal to the position report speaker, which is received by the radio frequency transceiver 20. This signal is used to activate the position acquisition control device 30 to receive the position signal. Then the position signal is prepared and transmitted to the communication system. When the user cannot manually activate the location acquisition control device 30, the communication system can remotely activate the location acquisition control device 30 to track the location of the user. In one embodiment, the user activates a switch, such as pressing an activation button, to manually activate the position acquisition control device 30.

In one embodiment, the communication system includes a control center 40 and a processing center 50. The control center 40 includes a signal receiving device 41 and a signal decoding device 42. The signal receiving device 41 receives the position radio frequency signal broadcast by the radio frequency transceiver 20 and down-converts it to a baseband signal.

As described above, depending on the location of the processing center 50, a police officer carrying a location reporting intercom device will periodically report his location to the patrol car or the police station. If multiple police officers take enforcement actions at the same time within the coverage area of the local communication system, and each police officer carries a position reporting interphone, then the location of each police officer will be reported to the processing center 50 regularly. If one of the police officers (such as the on-site commander) needs to know the location of other police officers, the relevant information will be sent to the position reporting phone of that police officer. When the policeman receives the above-mentioned information, he can connect his position reporting phone to such as a monitor, personal digital assistant (PDA), notebook computer, or any other device that can display the above-mentioned information through the interface component 4. In one embodiment, a police officer connects his PDA to the interface element 4 to receive the content transmitted from his position reporting phone. To put it simply, a processing center 50 (such as a police station) can send location data of all units to all location reporting interphones within the coverage of its communication system. Each police officer can connect his position report talker to a computer, monitor, PDA, or other display device to display the position of all police officers within the relevant range. With this creation, many similar applications can also be expected, such as the application in battlefields, and the application in forest and building fire extinguishing.
