Abstract
The utility model relates to an interphone with a Big Dipper positioning function. The interphone comprises an interphone circuit arranged in a machine case, wherein a base band processing module in the circuit is respectively connected with a confidentiality module, an interface circuit, a power supply and charging circuit, a microphone, a Big Dipper receiving module, a press key, a display screen and a loudspeaker, an ultra-short wave antenna is connected with the confidentiality module through a signal channel module, a Big Dipper antenna is connected with the Big Dipper receiving module, an external interface is connected with the interface circuit, and a battery is connected with the power supply and charging circuit. The interphone has the characteristics that the position information of each terminal can be transmitted to command terminals in real time, the position distribution and the proceeding conditions of each terminal in a site can be intuitively displayed through software, the commands are fast issued, and the dispatching and commanding efficiency is greatly improved. The voice data of each terminal can be encrypted, the confidentiality is good, the application environment is diversified, and the mutual talkback of various terminals and transmission of the terminal position information to the command terminal can be realized in a region with a range being about 5km.
Description
Technical field
The utility model relates to a kind of intercom with Big Dipper positioning function.
Background technology
At present terminal use's locating and displaying is mainly contained two kinds of methods; A kind of AGPS technology that is mobile phone passes through cellular network can be located; Positioning accuracy is within tens meters; Second kind is that mobile phone or the cluster intercom that is built-in with GPS utilizes the mobile phone cellular network that user's locating information is sent to the manager, and positioning accuracy is in ten meters.At present still not with the big-dipper satellite position application in the cluster intercom, and the technology that these are military just, alert usefulness, fire-fighting, frontier defense etc. need be used.
Summary of the invention
In view of the present situation and the development need of prior art, the utility model provides a kind of intercom with Big Dipper positioning function.Through increase Big Dipper locating module on intercom, and pass through the positional information that the ultrashort wave digital transmission module transmits the Big Dipper, make intercom possess the function that the Big Dipper is located and terminal location information is uploaded.
The utility model is for realizing above-mentioned purpose; The technical scheme of being taked is: a kind of intercom with Big Dipper positioning function; It is characterized in that: comprise the intercom circuit that is arranged in the casing; Its circuit is connected to: baseband processing module is connected with security module, interface circuit, power supply and charging circuit, microphone, Big Dipper receiver module, button, display screen, loud speaker respectively, and ultrashort wave antenna is connected with security module through channel module, and Big Dipper antenna is connected with Big Dipper receiver module; External interface is connected with interface circuit, and battery is connected with power supply and charging.
The characteristics of the utility model are: through using this terminal; In the intercommunication conversation of having satisfied real time communication; Each location information of terminals of transmission that can be real-time is to commanding the terminal; Show each terminal position distribution, situation of advancing at the scene intuitively through software, fast it is assigned instruction, significantly improved the efficient of dispatch control.Can encrypt each terminal speech data, good confidentiality, suitable environment is various.
Under some environment such as airport, goods yard, frontier defense, on-the-spot operation, rescue command, commander's station needs and can keep the intercommunication conversation with each terminal, obtains information, issues an order in real time, and need monitor the position at each terminal constantly.In order to satisfy this demand, designed this terminal, enable in 5 kilometers left and right sides scope area, the mutual intercommunication at each terminal, and to commander's end transmission terminal positional information.
Description of drawings
Fig. 1 connects block diagram for the utility model circuit.
Embodiment
As shown in Figure 1; A kind of intercom with Big Dipper positioning function comprises the intercom circuit that is arranged in the casing, and its circuit is connected to: baseband processing module is connected with security module, interface circuit, power supply and charging circuit, microphone, Big Dipper receiver module, button, display screen, loud speaker respectively; Ultrashort wave antenna is connected with security module through channel module; Big Dipper antenna is connected with Big Dipper receiver module, and external interface is connected with interface circuit, and battery is connected with power supply and charging.
Adopt 118-137MHz wave band ultrashort wave intercom module; Can satisfy in the 5KM scope; Speech talkback between each terminal room, each terminal and commander's station needs, and can increase the speech security function, makes it can be applied in the environment that information security is had relatively high expectations and uses down.The terminal positional information that Big Dipper receiver module receives is handled through baseband processing module, passes mode through ultrashort wave number, is sent to the commander terminal.
Adopt Big Dipper receiver module to receive the locating information of big-dipper satellite, obtain the exact position that the terminal belongs to, and send it to ultrashort wave digital transmission module, be sent to the commander terminal.Positioning accuracy can reach 20 ~ 100 meter 1 σ, can be promoted to 1 meter 1 σ behind the increase Local Area Augmentation System.
