Interphone device with positioning function

Abstract

The invention provides an interphone device with a global positioning function. The interphone device comprises a wireless transceiver module, a GPS (Global Positioning System) receiving module, a control processor, an audio processing module, a memory, an LCD (Liquid Crystal Display) screen, a key group and a power supply module, wherein a positioning execution program is established in the control processor and comprises at least one of three subprograms, namely a send-only positioning program, a receive-only position program and a transceiver position program; the positioning execution program is used for enabling the GPS receiving module to receive position information from a GPS satellite and enabling the wireless transceiver module to transmit the position information of the positioning execution program or receive position information of at least one member in a cluster; the control processor is used for further capturing at least one map corresponding to geographic coordinates within the duty range of the control processor, and is used for combining position information of all members and reflecting all the information on the map so as to generate a position point corresponding to each member and defining the position point of the control processor on the map to be displayed at the center of the LCD screen so as to form a cluster positioning system.

Description

technical field [0001] The present invention relates to a walkie-talkie device, in particular to a group that can transmit and receive location information of itself and the same group that has the same global positioning function enabled, and display the current location of each group member on the map of the LCD screen of the walkie-talkie carried by it GPS. Background technique [0002] Commonly used walkie-talkie (walkie-talkie, including Analogy / Digital Radio System) is mainly aimed at public security, enterprises and institutions and other professionals (such as police, fire, security, medical, rescue teams, etc.) to achieve one-to-one or one-to-many regional real-time communication devices, and generally can only transmit voice or short message information; , vehicles, etc.), with the help of the positioning system, it is very important to be able to know the location of the person using the above-mentioned equipment or the equipment itself, especially in search or r...

Problems solved by technology

[0003] As mentioned above, the walkie-talkie device with GPS function specially used by rescue groups can only provide its own location information to the dispatch center or the server of the communication system, which is not enough; because it can only send its own location information one-way, and It is impossible to take the initiative to understand the mutual positions of the team members at any time. Under such circumstances, it is impossible to achieve greater help for the entire group to perform rescue tasks.

Also, as mentioned above, the traditional walkie-talkie device using GPS system positioning is not suitable for positioning instructions in small areas or within the same building, because the position signals may overlap or be blocked by buildings and cannot be identified
